, Description:FIELD OF THE DISCLOSURE

The present subject matter generally relates to field of wireless communication. More particularly, but not exclusively, the present disclosure discloses a base station and method for scheduling one or more User Equipment (UE) in a wireless network.

BACKGROUND
In a wireless network, which may be a cellular and a non-cellular network such as Internet of Things (IoT) technologies, Machine to Machine (M2M) communication, or any other wireless technologies, there exist communication between base station (may also referred as remote server or Evolved Node B (eNodeB)) and one or more UE located in that wireless network. The communication involves a mechanism to transmit and receive data periodically by at least one of the one or more UE and the base station. The transmission and reception of the data is based on schedule allotted by the base station to each of the one or more UE.

In existing technology, the base station schedules at least one of UE in the wireless network covered by the base station based on request from the UE for scheduling Uplink (UL) channel. There are multiple mechanisms implemented for scheduling the one or more UE which may differ with respect to factors applicable for determining schedule or based on periodicity of the scheduling. Upon scheduling, the base station provides grant of UL scheduling to the corresponding UE based on which the data is transmitted and received. In some of existing mechanisms, the scheduling may be based on multiple parameters associated with the UE such as buffer size data, Channel Quality Indication (CQI), location data, timing advance data, periodicity data, channel allocation data and so on.

One of existing mechanisms for scheduling discloses resource scheduling a group of UE such as IoT or M2M devices in a network for a periodic duration persistently. The base station is configured to club traffic or data from the group of UE in an allocated Resource Block (RB). Other existing mechanisms disclose scheduling user devices on a wireless network based on first and second fading metric to one base station and to other base station respectively. Said mechanisms use the user device with larger first metric to be prioritized over other user devices.

With advancement in the technology, the base stations are configured to connect to the UE in one or more adverse conditions providing low data rate with very high energy efficiency. Adverse conditions may arise when a UE located in a basement or buried deep in soil or when location of a UE with respect to the base station changes continuously. In some of the networks, the number of UE connected to a single base station may be large. In such scenarios, there exists limitation of handling number of UE by the single base station to establish an efficient communication with each of the UE. Scheduling the UE in a given instance using one or more Resource Element (RE) of UL Resource Block (RB) is also a challenge to the base station. Also, scheduling of the UE with least amount of power consumption is needed in case of a network with battery driven UE such as IoT devices which may last over 5 to 10 years. There is also a need for an efficient scheduling mechanism which may handle interference from other base stations.

The information disclosed in this background of the disclosure section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

The present disclosure provides efficient method for scheduling one or more User Equipment (UE) by a base station in a wireless network even with large number of UE. An exemplary method of the present disclosure discloses to schedule the one or more UE with minimal power consumption. The method includes scanning of the one or more UE by radiating beam radially using a directional antenna unit associated with the base station in coverage area of the base station. At any instant of time, the one or more UE, which is scanned by the base station, communicates with the base station for the scheduling. The scanning includes three scans of the one or more UE for the scheduling and receiving data from the one or more UE which is scheduled. The base station, in first scan of the one or more UE, receives scheduling request from the one or more UE located in radial region of the beam. Upon receiving the scheduling request, the base station determines the schedule for data from the one or more UE based on one or more UE parameters. In second scan of the one or more UE, the base station transmits the determined schedule to the one or more UE. Based on the received schedule, the UE transmits data to the base station in third scan of the one or more UE.

Figure 1A and 1B illustrate embodiments of a system 100 for scheduling one or more UE 102…102.N (hereinafter collectively referred as one or more UE 102) in a wireless network in accordance with some embodiments of the present disclosure.

The system 100 for scheduling the one or more UE 102 comprises of a base station 101 and the one or more UE 102. The base station 101 further comprises a directional antenna unit 104, a processor 105, an I/O interface 106, modules 107 and a memory 108. In a non-limiting embodiment, the directional antenna unit 104 may not be a part of the base station 101, wherein the directional antenna unit 104 may be communicatively coupled to the base station 101 through external means for scheduling the one or more UE 102. The memory 108 in the base station 101 is communicatively coupled to the processor 105. The memory 108 stores processor executable instructions which on execution enable the base station 101 to schedule the one or more UE 102. The one or more UE 102 in the system 100 may be a device which is configured to transmit and receive data with the base station 101 and may be located under coverage region of the base station 101. In an embodiment, the one or more UE 102 may be devices relating to IoT which may include, but are not limited to, electric meters, water meters, industrial sensors, air pollution sensors, water pollution sensors and so on. In one embodiment, location of the one or more UE 102 may be one of constant and varying with respect to location of the base station 101 in the wireless network. The base station 101 communicates with the one or more UE 102 via the communication network 103. In one embodiment, the communication network 103 may be one of a cellular network and a non-cellular network. In a non-limiting embodiment, the base station 101 may use one of physical layer and Media Access Control (MAC) layer technology and any other technology known to a person skilled in the art to connect to the one or more UE 102.

For scheduling and obtaining the data from the one or more UE 102, the base station 101 performs scanning of the one or more UE 102. The scanning involves first scan, second scan and third scan of the one or more UE 102. The directional antenna unit 104 associated with the base station 101 rotates at a predetermined rate and radiates beam 109 at a predetermined angle radially along coverage area of the base station 101 for the scanning. The coverage area may be a circumferential area around the base station 101 within which the base station 101 may establish a communication with the one or more UE 102 in that coverage area. Each rotation of the directional antenna unit 104 may be considered as one cycle. In an embodiment, the directional antenna unit 104 may rotate for 360 degrees per cycle. The directional antenna unit 104 may be rotated either physically or electronically for the scanning. In a non-limiting embodiment, the directional antenna unit 104 may be a narrow-beamed antenna that may be created using an array antenna or physical antenna design. Here, each of the one or more UE 102 is aware of time instant of their scanning. In an embodiment, the one or more UE 102 may be in sleep mode and during each of the scanning, i.e., the first scan, second scan and the third scan, the one or more UE 102 may wake up from the sleep mode to communicate with the base station 101. By this, power consumption of the one or more UE 102 is reduced efficiently. After UE 102 wakes up to communicate with the base station at the approximate time of scan, the UE102 first synchronizes itself with the base station 101 to meet the scan cycle perfectly. In a non-limiting embodiment, the first scan, the second scan and the third scan may not happen in consecutive cycle of rotation of the directional antenna unit 104.

During the first scan of the base station 101, the one or more UE 102 located in a radial region of the beam 109 radiated by the directional antenna unit 104 transmits a scheduling request to the base station 101. In an embodiment, if the one or more UE 102 is in the sleep mode, the one or more UE 102 wake up from the sleep mode to transmit the scheduling request at the instant of scanning. Upon receiving the scheduling request, the base station 101 determines a schedule for the data for the one or more UE 102 based on one or more UE parameters associated with the one or more UE 102. The one or more UE parameters comprises at least one of location data, timing advance data, periodicity data, buffer size data, channel allocation data and Channel Quality Indication (CQI) associated with the each of the one or more UE 102. In a non-limiting embodiment, the one or more UE parameters may be any other parameters associated with the one or more UE 102 for determining the schedule for the data.

During the second scan of the one or more UE 102, the determined schedule for the data is transmitted to the corresponding the one or more UE 102 which are along the radial region of the beam 109. Even in the second scan, the one or more UE 102, if in sleep mode, may wake up from the sleep mode to receive the schedule at time when the one or more UE 102 is scanned in the second scan. In an embodiment, the determined schedule may be transmitted to the corresponding one or more UE 102 via a common control channel in the wireless network. In an embodiment, the schedule comprises grant of a resource element with RB in the wireless network to each of the one or more UE 102. The grant of the resource element may be based on the timing advance data associated with the corresponding one or more UE 102. In frequency domain, the schedule is also based on sub-carrier channel to be allocated to each of the one or more UE 102.

During the third scan, the one or more scheduled UE 102, located along the radial region of the beam 109, transmits the data to the base station 101 on the scheduled RB. In an embodiment, the data is transmitted by each of the one or more UE 102 in the allocated channel, which may be Physical Uplink Shared Channel (PUSCH), in the uplink using the RB allocated for said channel. In an embodiment, the data is transmitted from the one or more UE 102 in the wireless network to the base station 101 via traffic channel which may be Down Link Shared Channel (DL-SCH) or Uplink Shared Channel (UL-SCH). In another embodiment, the data is received via the traffic channel by the one or more UE in the wireless network from the base station.

Consider a wireless network as shown in Figure 1B, with the base station 101 and one or more UE 102.1-102.8. As shown in the figure, the one or more UE 102.1-102.8 may be any device which is configured to communicate with the base station 101. In an embodiment, the one or more UE 102.1-102.8 may be devices relating to IoT which may include, but are not limited to, electric meters, water meters, industrial sensors, air pollution sensors, water pollution sensors and so on., and the like. One or more illustrations of the one or more UE 102.1-102.8 is shown in Figure 1B. The location of the one or more UE 102.1-102.8 may be one of constant or varying with respect to the base station 101 at any instant of time. For scheduling the one or more UE 102.1-102.8, the base station 101 performs the scanning of the one or more UE as described previously. The directional antenna unit 104 associated with the base station 101 rotates mechanically or electronically at a predetermined rate and radiates the beam 109 of a predetermined angle along the radial region of the base station 101 as shown in the figure for the scanning. Consider, at an instant of time, UE 102.1 and UE 102.8 of the one or more UE 102.1-102.8 are located along the direction of the beam 109. Here, the one or more UE 102.1-102.8 are aware of time of scan of the corresponding one or more UE 102.1-102.8. Consider, the base station 101 rotates 360 degrees in each cycle of rotation.

Now, at first cycle of the rotation, there is a need for the UE 102.1 to communicate with the base station 101. Since the UE 102.1 is aware of the time of scan, the UE 102.1 wakes up from the sleep mode at the first scan of the directional antenna unit 104 i.e., at rough instant when the beam 109 is radiated towards the UE 102.1. Once the UE 102.1 wakes up from sleep mode and synchronizes fully with the base station 101, communication is enabled between the UE 102.1 and the base station 101 and the UE 102.1 transmits a scheduling request to the base station 101. The base station 101, upon receiving the scheduling request, determines the schedule for data from the UE 102.1 based on one or more parameters.

During second cycle of the rotation of the directional antenna unit 104, there is a need for the UE 102.8 to communicate with the base station 101. When the beam 109 is radiated along the radial direction of location of UE 102.1 and the UE 102.8, the UE 102.8 may wake up from the sleep mode and transmits the scheduling request to the base station 101. For the UE 102.8 this would be its first scan. Further, in the second cycle the determined schedule for the data from the base station 101, is transmitted to the UE 102.1. The second cycle would be at second scan for UE 102.1. Now, the schedule for data from the UE 102.8 is determined by the base station 101.
During the third cycle of the rotation of the directional antenna unit 104 which is the third scan for UE 102.1 and second scan for UE102.8, the determined schedule for the data from the base station 101 is transmitted to the UE 102.8 by the base station 101 and the data is received from the UE 102.1 by the base station 101 based on the schedule of the UE 102.1.

At fourth cycle of the rotation of the directional antenna unit 104, which is third scan of the UE 102.8, the UE 102.8 transmits the data to the base station 101 based on the schedule of the UE 102.8. Similarly, other one or more UE (which are 102.2-102.7) may also transmit the data to the base station 101 in the respective third scan upon the respective first scan and second scan.

In one embodiment, the first scan, the second scan and the third scan may not happen in consecutive cycle of rotation of the directional antenna unit 104. The first scan, the second scan and the third scan are used to determine the sequence of events of sending the scheduling request to the base station 101 by the one or more UE 102, receiving the schedule from the base station 101 and then transmitting the data based on the schedule.

In one embodiment, there may be one or more cycles of rotation of the directional antenna unit 104 without performing actions of the first scan, the second scan and the third scan on the one or more UE 102. This may be considered as free cycle rotation. The free cycle rotation may happen between the first scan, the second scan and the third scan. There may be one or more free cycle rotation the one or more UE 102 may encounter between the first scan, the second scan and the third scan.

Figure 2 illustrates a detailed block diagram of the base station 101 for scheduling the one or more UE 102 in the wireless network in accordance with some embodiments of the present disclosure.

In an embodiment, data in the memory 108 are processed by the modules 107 of the base station 101. In one embodiment, the modules 107 may be stored within the memory 108 (not shown in Figure). In an example, the modules 107, communicatively coupled to the processor 105, may also be coupled to the memory 108 and implemented as hardware. As used herein, the term module refers to an application specific integrated circuit (ASIC), an electronic circuit, a field-programmable gate arrays (FPGA), Programmable System-on-Chip (PSoC), a combinational logic circuit, and/or other suitable components that provide the described functionality. The said modules when configured with the functionality defined in the present disclosure will result in a novel hardware.

In one implementation, the modules 107 may include, for example, a scheduling request receiving module 201, a schedule determining module 202, a schedule transmitting module 203, a data obtaining module 204 and other modules 205 associated with the base station 101.

In one embodiment, the data in the memory 108 may include, for example, a scheduling request data 206 also referred as scheduling request 206, a schedule data 207 also referred as schedule 207, data 208 from one or more UE 102, one or more UE parameters 209, a predetermined rate 210, a predetermined angle 211, cycle of rotation 212 and other data 213 associated with the base station 101. In one embodiment, the scheduling request 206, the data 208 from one or more UE 102 and the one or more UE parameters 209 may be received by the base station 101 in real-time via I/O interface 106 for scheduling the one or more UE 102. In one embodiment, the schedule 207 may be transmitted by the base station 101 in real time via I/O interface 106 for scheduling the one or more UE 102.

The base station 101 performs the scanning of the one or more UE 102 for scheduling and receiving the data 208 from the scanned one or more UE 102. The directional antenna unit 104 associated with the base station 101 rotates at the predetermined rate 210 and radiates beam 109 at the predetermined angle 211 radially along the coverage area of the base station 101 for the scanning. The predetermined rate 210 may be rate at which the directional antenna unit 104 rotates, radiating the beam 109, for scanning. The predetermined angle 211 of the beam 109 may be area covered by the beam 109 at any instant of time during the scanning. In the embodiment, the predetermined angle 211 may be 60 degrees i.e., the radiated beam 109 covers 60 degrees of the coverage area of the base station 101 at any instant of time. Each rotation of the directional antenna unit 104 is considered as the cycle of rotation 212 which may be one of the first scan, the second scan and the third scan for any of the one or more UE 102. In an embodiment, the cycle 212, the predetermined rate 210 and the predetermined angle 211 is determined based at least one of the one or more UE parameters 209. The one or more UE parameters 209 may be one of the location data, the timing advance data, the periodicity data, the buffer size data, the channel allocation data and the CQI associated with the each of the one or more UE 102.

The location data of each of the one or more UE 102 provide location information of the corresponding UE with respect to the location of the base station 101. The timing advance data of each of the one or more UE 102 may be time taken by the data 208 to reach the base station 101 from the corresponding one or more UE 102. The periodicity data of each of the one or more UE 102 provides the time interval at which the corresponding UE transmits the data 208. The buffer size data of each of the one or more UE 102 and the CQI information provides time taken for receiving the data 208 from the corresponding one or more UE 102. The channel allocation data of each of the one or more UE 102 provides information of allocated channels for the corresponding one or more UE 102 in the wireless network. The CQI of each of the one more UE 102 provides information indicates a suitable downlink transmission data rate of the corresponding one or more UE 102 for the transmission from the base station 101. The one or more UE 102 are assumed to be time synced and frequency synced to the base station 101 and the base station 101 is aware of the one or more UE parameters 209 of each of the one or more UE 102 in the coverage area.

In an embodiment, the cycle 212, the predetermined rate 210 and the predetermined angle 211 are based on highest value of the timing advance data associated with the one or more of the UE 102. Any of the one or more UE 102 in cell edge of the coverage area of the base station 101 may have the highest value of the timing advance data. Farther away is said UE from the base station 101, highest is the timing advance data of that UE. For example, consider in Figure 1B, at first instant of time, UE 102.6 is having the worst time advance data amongst all the other one or more UE 102 under the coverage area of the base station 101. In this scenario, the timing advance data of the UE 102.6 is considered for the determining the cycle 212, the predetermined rate 210 and the predetermined angle 211. Consider, at second instant of time, UE 102.4, whose location may be varying with respect to the location of the base station 101, is having the worst timing advance data amongst all the other one or more UE under the coverage area of the base station 101. In this scenario, the timing advance data of the UE 102.4 is considered for the determining the cycle 212, the predetermined rate 210 and the predetermined angle 211. In an embodiment, the cycle 212, the predetermined rate 210 and the predetermined angle 211 may also depend on variations of the periodicity data associated with each of the one or more UE 102. In a scenario where the cycle 212, the predetermined rate 210 and the predetermined angle 211 vary due to the variations in the one or more UE parameters, a super cycle is established. Super cycle is the cycle of rotation of the directional antenna unit 104 which occurs due to the variations in the one or more UE parameters 209. Information indicating the occurrence of super cycle is specified in advance to each of the one or more UE 102 via a control channel in the wireless network. In an embodiment, the super cycle may not be applicable if the one or more UE 102 are at fixed location with respect to the base station 101.

During the first scan of the one or more UE 102, the scheduling request receiving module 201 of the base station 101 receives the scheduling request 206 from the one or more UE 102 located in the radial region of the beam 109 radiated by the directional antenna unit 104. In an embodiment, an uplink communication is established between the base station 101 and the one or more UE 102 through which the scheduling request 206 is received by the base station 101.

Upon receiving the scheduling request 206, the schedule determining module 202 of the base station 101 determines the schedule 207 for the data 208 for the one or more UE 102 based on one or more UE parameters 209 associated with the one or more UE 102.

During the second scan of the one or more UE 102, the schedule transmitting module 203 of the base station 101 transmits the schedule 207 to the corresponding one or more UE 102 located along the radial region of the beam 109. In an embodiment, a downlink communication is established between the base station 101 and the one or more UE 102 through which the schedule 207 is transmitted to the one or more UE 102. Upon receiving the schedule 207, the one or more UE 102 is aware of the allocated channel and the resource element for transmission of data 208 to the base station 101. The one or more UE 102 is also aware of the instant at which the respective UE is scanned. During the third scan, the data 208 obtaining module 204 of the base station 101 obtains the data 208 from the one or more UE 102 based on the received schedule 207. In an embodiment, an uplink communication is established between the base station 101 and the one or more UE 102 through which the data 208 is received by the base station 101.

In an embodiment of the present disclosure, the other modules 205 of the base station 101 may comprise a cycle determining module for determining the cycle of rotation 212, a predetermining rate determining module for determining the predetermined rate 210 and the predetermined angle determining module for determining the predetermined angle 211.

In an embodiment of the present disclosure, the other modules 205 of the base station 101 may comprise a synchronization module with clocking from Global Positioning System (GPS) or Synchronous Ethernet (SyncE)/Precision Time Protocol (PTP)/ Network Time Protocol (NTP) for establishing synchronization in the time domain and the frequency domain with the one or more UE 102.

In an embodiment of the present disclosure, the other modules 205 of the base station 101 may comprise Ethernet switching module for backhaul an external Remote Radio Head (RRH) for power amplification of RF signal.

In an embodiment of the present disclosure, the other modules 205 of the base station 101 may comprise one of motor and a beam former to enable rotation of the directional antenna unit 104.

In an embodiment of the present disclosure, the other modules 205 of the base station 101 may comprise interference reduction module which is configured to reduce interference occurring due to other base stations located nearby to the base station 101. The base station 101 coordinates with the other base stations through the interference reduction module by which at any instant of time either the base station 101 or one of the other base stations enables communication with the one or more UE 102. This coordination of the base stations in the wireless network reduces interference from the downlink channel. For example, the interference reduction module enables the one or more UE 102 to connect to the base station 101 with highest value of Signal to Noise Ratio (SINR). In a scenario where, a scheduling is sent to more than one base station, the base station 101 coordinates with each other and one of the base stations only determines the schedule 207 and transmits the schedule 207 to the one or more UE 102. Also, the interference reduction modules monitor at least one of the cycle 212, the predetermined rate 210 and the predetermined angle 211 to avoid slight time synchronization mismatch between the one or more UE 102 and the base station 101 and to reduce the interference from the downlink channel.

At block 301, the scheduling request receiving module 201 of the base station 101 receives the scheduling request 206 from the one or more UE located in the radial region of the beam 109 radiated by the directional antenna unit 104.

At block 302, the schedule determining module 202 of the base station 101 determines the schedule 207 for the data 208 for the one or more UE 102. The schedule 207 may be based on one or more UE parameters 209 associated with the one or more UE 102.

At block 303, the schedule transmitting module 203 of the base station 101 transmits the schedule 207 to the corresponding one or more UE 102 located along the radial region of the beam 109. Based on the schedule 207, the one or more UE 102 transmit the data 208 to the base station 101.

Further, during the second scan of the scanning of the UE 102, at step 406, the directional antenna unit 104 radiates the beam 109 radially towards the UE 102 and at step 407, the schedule 207, received from the base station 101 at step 405, is sent to the UE 102. During the third scan, at step 408, the directional antenna unit 104 radiates the beam 109 radially towards the UE 102 and at step 409 the data 208 is transmitted from the UE 102 based on the schedule 207 to the directional antenna unit 104. At step 410, the base station 101 receives the data 208 via the directional antenna unit 104.
