For clarity and conciseness, in the specification are not all features of an actual implementation. However, it should be understood that many decisions must be made to the specific embodiments of the development of any such actual embodiment of the process in order to achieve the developer's specific goals, such as compliance with those restrictions related systems and services, and these restrictions may be subject to change with different embodiments.

[0030]

[0031]

[0032]
Figure 1 shows a block diagram of an apparatus 100 for wireless communication with the user equipment side according to one embodiment of the present disclosure according to the apparatus 100 includes: an information obtaining unit 101, configured to obtain the user equipment serving cell and / or phase neighbor cells for a cell-specific offset of dynamic radio resource management information, wherein the cell-specific transmission capacity dynamic offset corresponding to the relevant cell, transmission capability includes at least one multi-antenna transmission performance gain cell, load condition; measuring means 102, serving cell configured to measure and reference signals from neighboring cells; and a cell reselection / measurement reporting unit 103, is configured according to the connection state of the user equipment, and the cell-specific dynamic offset of the serving cell and neighboring cells the results of measurement report or a cell reselection. In the prior LTE system, since the user equipment reports the measurement values ​​for the cell switching, radio resource management operations only for the performance gain of multi-antenna transmission antenna port corresponding to a single channel, the base station cell is ignored, it may cause a user e.g. Since the device does not have access to multiple antenna transmission and greater performance gain better access to the actual performance of the cell due to multi-antenna transmission performance gain is small and the actual situation of poor cell performance.
[0033]
In the apparatus 100, the information acquisition unit 101 acquires the user equipment serving cell and / or cell-specific dynamic offset information for the neighboring cell radio resource management, and the cell reselection / measurement reporting unit 103 performing cell reselection or cell-specific information using the dynamic offset measurement report, it is possible to better determine the actual performance of the cell more accurately. Wherein the dynamic offset is a cell-specific cell-specific and may be dynamically changing, different cells typically have different dynamic offset value.
[0034]
Specifically, the information acquisition unit 101 may acquire a serving cell (own cell) both the cell-specific cell and the adjacent dynamic offset information can be acquired only either. For example, the measurement report is configured for cell handover event may be acquired only neighboring cells dedicated dynamic offset, which is considered to be present as the base station knows the nature of the particular circumstances of this cell performing radio resource management decisions; when cell reselection is performed, for example, the information acquisition unit 101 may acquire only a cell-specific dynamic offset of the cell, for example, a cell reselection / measurement unit 103 may report the measurement result of the cell to the present cell-specific dynamic offset and summed with cells with other measurements to determine a cell to be accessed, to avoid frequent cell reselection.
[0035]
Cell reselection / measurement reporting unit 103 is in a state such as radio resource control (RRC) connected state of the user equipment according to the connection to a cell based on measurements and specific dynamic offset measuring unit 102 performs a cell reselection or measurement reporting . For example, when the RRC connected state, the measurement reports, RRC and unconnected state (IDLE) performs a cell reselection.
[0036]
In one example, the measurement result of the measurement unit 102 comprises at least one associated measurement value (RSRQ) and the reference signal received power (RSRP) and Reference Signal Received Quality.
[0037]
For example, the cell reselection / measurement reporting unit 103 may be configured to rank the measured cells based on cell-specific information and the dynamic offset measurements, and determines a cell to be accessed based on the sorting result. By way of example, cell reselection / measurement reporting unit 103 may incorporate a proprietary dynamic offset information and measurement results of each cell to obtain a cell transmission performance of the cell, and the transmission performance of the best cell determined as the cell to be accessed. Alternatively, the cell reselection / measurement reporting unit 103 may transmit signaling and better performance can be guaranteed in the cell as a cell to be accessed is determined, this example applies to signaling, for example, some other control signaling PDCCH signaling is not after multiple-antenna processing gain and thus can not enjoy multi-antenna case, and therefore need to ask the user equipment receives the signaling quality reaches a certain level, for example, the measurement result itself may be required to reach a certain threshold value.
[0038]
For example, during cell reselection, the user equipment can be sorted based on the measured cell-specific dynamic offset information and measurement results acquired cell, and selects the best access to the cell transfer performance. It will be appreciated, may be further combined with the existing rule-based cell reselection in the cell reselection of the present invention on the idea, the present invention is not intended to be limiting.
[0039]
In one specific example, a user equipment to a serving cell and a reference signal is measured and the neighboring cell respectively to measure RSRP measured value Q MEAS, S and Q MEAS, n- , comprising a cell-specific offset based on the base station dynamically notified the cell reselection parameters for cell sorting according to the following formula:
[0040]
Rs’＝Qmeas,s+QHyst-Qoffsettemp+Qoffsetdyn,s (1)
[0041]
Rn’＝Qmeas,n-Qoffset-Qoffsettemp+Qoffsetdyn,n (2)
[0042]
Wherein, R S ' representative of the reference value R for the serving cell involved in cell sorting, R n-' representative of the reference value R for the neighboring cell involved in cell sorting, Q offsetdyn, S cell cell-specific services on behalf of dynamic offset, Q offsetdyn, n cell neighbor cell specific representatives dynamic offset, in addition, as specified in 3GPP TS36.331 and technical standards specified in TS 25.331, Q Hyst hysteresis value representative of the ranking criteria, Q offset based serving cell and neighbor cells is correspondingly intra-frequency or inter-frequency representing the frequency shift or offset between two specific OAM cell statically configured, Q offsettemp representative of the temporary offset value of each cell in common. The user equipment according to the reference value R calculated as described above, all the cells satisfy the S criterion to sort, select the best cell in the first row perform a cell reselection operation in some examples.
[0043]
In another alternative example, the user equipment first reference value R is calculated according to the guidelines in the existing standard R s and R n- , for example according to the following equation:
[0044]
Rs＝Qmeas,s+QHyst-Qoffsettemp (3)
[0045]
Rn＝Qmeas,n-Qoffset–Qoffsettemp (4)
[0046]
Wherein, the formula (3), and the same reference numerals represent the formula (1) and the same meaning as in (2) (4). Thereafter, the user equipment selected reference value R n- greater than the serving cell R S of the plurality of candidate neighbor cells, which then calculates R for a plurality of candidate adjacent cell n ' and cell sorting, in which R n' maximum value o as such a cell reselection target cell reselection to the best actual transmission performance. In this example, the user equipment without the use of a cell-specific offset of dynamic serving cell Q offsetdyn, S , and therefore the value may not be provided signaling consumption is reduced.
[0047]
Those skilled in the art according to the prior art and the above-described example other combinations may be devised or modified manner, for example, the user equipment receives only the base station Q offsetdyn, S and Q offsetdyn, n- difference as respective neighboring cells cell-specific dynamic offset , and in calculation of R & lt n-' used when Q offsetdyn S, and Q offsetdyn, n- difference, and with R & lt S to sort cells, the present invention does not enumerate herein.
[0048]
Wherein the information acquiring unit 101 may acquire the information through a cell-specific offset dynamic system information or history information recorded in the user equipment. Wherein, for example, acquires system information through a broadcast channel (e.g. the BCCH), the cell and the adjacent cell and the cell obtained from the history information, for example, when one of the access cell before the user equipment-specific dynamic offset information. Alternatively, the history information of the cell may be a cell-specific dynamic offset information each time the user access to a device when the recorded cell. A cell information acquisition unit 101, for example, cell-specific dynamic offset information when the user equipment is in the RRC idle system information or history information such as, for example, to perform adjacent cell reselection.
[0049]
In addition, further information acquisition unit 101 may acquire cell-specific dynamic serving cell and neighbor cell offset information received by the RRC signaling from the base station serving the cell. For example, the information acquisition unit 101 acquires neighboring cell to establish the ID and the corresponding dynamic offset information in the user equipment an RRC connection with a serving cell, e.g., obtain dynamic information in each cell unit SystemlnformationBlockType4 RRC message and / or the partial SystemInformationBlockType5 shift information. Using previously recorded in the RRC idle state dynamic neighbor cell information and the neighbor cell offset the acquired ID to determine the current neighbor cell measured dynamic offset information.
[0050]
Multi-antenna transmission performance gain above may include, for example, a cell gain precoding and / or beamforming gain. Further, in one example, a cell-specific dynamic offset is also related with the load cell, wherein the larger the load, the smaller the offset value.
[0051]

[0052]
The following exemplary apparatus for measurement reporting for a wireless communication device side of the user according to the present application will be described. Typically, the base station through higher layer signaling to the user equipment a radio resource management (RRM) measurement configuration, and make decisions based on radio resource management RRM measurements by the user equipment according to the configuration of this cell and adjacent cells, for example cell handover, bis connection starts or adjust, start carrier aggregation or a carrier composition adjustment.
[0053]
In the present embodiment, the information acquisition lower unit 101 where is arranged as a radio resource control (RRC) of the user equipment connection state is connected, acquires the measurement of the serving cell from the user equipment configuration information, wherein the measurement configuration information e.g. including dynamic offset, and report on the consideration of the dynamic offset measurement report event trigger configuration.
[0054]
Note that this report is the triggering event of this application takes into account the new definition of dynamic events factors offset will be described in detail later. In other words, the information acquisition unit 101 acquires (base station) from the serving cell contains information considered and the related dynamic measurement reports dynamic offset triggering the trigger event or the like arranged offset. For example, the above dynamic measurements with cell-specific offset information may include configuration information in the RRC signaling, may be included in a MeasObjectEUTRA specific (such as in CellsToAddMod) RRC signaling, and the information about the measurement reporting configuration may include, for example, in in measconfig IE.
[0055]
As one example, the cell reselection / measurement reporting unit 103 may include: a measurement report triggering module configured to at least cell-specific dynamic offset, measurements and measurement reporting configuration to trigger a measurement report. For example, the measurement report triggering module dedicated dynamic offset in a cell and a measurement result of one or more cells satisfies a measurement report when reporting configuration defined event, was added to the cell ID and the measurement report measurement report is triggered, e.g. so as to be switched to the neighboring cell base station to report the best transmission performance by the measurement report neighbor cells.
[0056]
As another example, the cell reselection / measurement reporting unit 103 may include: a measurement report generation module, configured to meet the dynamic offset cell specific consideration of the results of the measurement report triggering events of neighboring cells included in the measurement report. In this case, the user-side device determines the target cell is not performed, but the measurement result reported to the base station, for example, the target cell is selected by the base station to perform a cell handover, dual link, carrier aggregation management operations.
[0057]

[0058]
The following examples will be described for the cell reselection apparatus for a wireless communication device side of the user according to the present application. In this example, the user equipment is in the RRC idle state, for example, the information acquisition unit 101 may acquire cell-specific system information via a dynamic offset information or the history information as described above, the cell reselection / measurement reporting unit 103 may be based on the cell-specific measurement result information and the measured dynamic offset unit 102 determines the best transmission performance of the cell as a cell to be accessed, for example, be determined by cell sorting embodiment of the first embodiment.
[0059]
Further, in FIG. 2, the apparatus 200 of this embodiment includes, in addition to the components of the device 100 of FIG. 1, reference addition, it may further comprise: a mark indicating a sending unit 201, configured to, after completion of the cell reselection, cell reselection to a target cell transmits a device capability flag cell considered in determining dynamic offset. Thus, for example, the target cell may be preferentially disposed multiple antenna transmission scheme for the user equipment.
[0060]
For example, the ability to mark the transmission unit 201 may be configured to transmit the RRC signaling device capability flag. Another example capability flag transmission unit 201 may be configured to transmit signaling device capability flag in the random access request.
[0061]
When the above-described apparatus 100 and 200 by performing a cell reselection or measurement reporting the cell-specific information into account dynamic offset can accurately reflect the actual performance of a cell thereby facilitating a more accurate decision.
[0062]

[0063]
Figure 3 shows a block diagram of an apparatus 300 for a base station side radio communication according to one embodiment of the embodiment according to the present disclosure, the apparatus 300 comprises: instruction generation unit 301, it is configured to generate a serving cell including a base station and / or adjacent dynamic cell information indicating a cell-specific radio resource management for the offset, the base station for indicating user equipment, wherein the dynamic offset cell specific transmission capacity corresponding to the relevant cell, a cell comprising a multi-antenna transmission capacity transmission performance at least one of gain, load condition; and a radio resource management unit 302, configured to offset radio resource management device based on a user-specific dynamic cell.
[0064]
As described above, the performance gain of multi-antenna transmission may include a gain cell precoding and / or beamforming gain. Dynamic offset may also be cell-specific and related to the load cell, wherein the larger the load, the smaller the offset value. Wherein the cell performance gain of multi-antenna transmission according to the load cell and the corresponding cell operation state is dynamic, for example the performance of multi-antenna transmission multiple antenna deployment cell may vary with the number of current users and services.
[0065]
In the apparatus 300, the instruction generation unit 301 generates cell-specific information contains an indication of the dynamic offset, and the wireless resource management unit 302 based on the dynamic offset to radio resource management such as handover cells, the double connector, carrier aggregation and other operations.
[0066]
Shown in phantom in FIG. 3, the apparatus 300 may further include a communication unit 303, the user equipment is configured to send indication information to the base station, and receiving an access request or a measurement report from the user equipment.
[0067]
In one example, the instruction generation unit 301 included in the dynamic offset cell specific system information, and the communication unit 303 transmits the system information is cell-specific dynamic offset via a broadcast channel. For example, the SIB system information, the present cell may be increased dynamic offset term (q-OffsetDyn) in the SystemInformationBlockType3 cellReselectionInfoCommon, to increase the dynamic offset term co-frequency adjacent cells (q-OffsetDyn) in the IntraFreqNeighCellInfo SystemInformationBlockType4, the SystemInformationBlockType5 InterFreqNeighCellInfo increase in dynamic offset terms of inter-frequency neighbor cells (q-OffsetDyn). For example, when the user equipment is in RRC idle, cell reselection may be performed by an operation to receive the system information.
[0068]
In another example, for example, in the RRC connected state in the user equipment, the instruction generation unit 301 included in the dynamic offset cell specific RRC signaling, and the communication unit 303 transmits a cell specific dynamic offset via a data channel RRC signaling. As described above, the dynamic offset information may be included in a MeasObjectEUTRA (such as in CellsToAddMod) RRC signaling, in addition, may be included in the RRC system information block, specifically, for example, included in the above-described SystemInformationBlockType3, SystemInformationBlockType4, SystemInformationBlockType5 in.
[0069]
Further, the instruction generation unit 301 may also be a cell-specific dynamic offset and a measurement report on the consideration of cell specific triggering event report dynamic offset configuration includes the RRC signaling measurement configuration information to a user equipment a measurement report . I.e., RRC signaling transmitted in the measurement report further comprises means for configuration of the user equipment. As described above, the measurement reporting configuration information may include, for example, in the measconfig IE. Further, may also include a base station MeasConfig desired user device a list of the measured cells, each parameter measurement reporting events, and the like. When the user equipment in accordance with the measurement of the configuration of each cell the measurement is completed, it is determined whether the measurement result satisfies a respective reporting trigger event based on the event parameters, if satisfied then report the cell ID, to meet the report triggering event ID and / or specific measurements, etc .
[0070]
As an example, a radio resource management unit 302 determines that the measurement result reported from the user equipment contained in an adjacent cell, based on the neighboring cell measurement result and corresponding cell-specific dynamic offset, determining a target user for the access device district. In this example, access to the target cell is determined by the base station side. In addition, the radio resource management unit 302 based on the report may trigger event corresponding to the measurement result, determines a target cell as the handover target access device user cell, double cell or a connection target at least one polymeric carrier in the target cell. For example, consideration may be provided for switching a cell-specific dynamic offset, the dual connector, the new carrier aggregation reporting trigger event and assigns a unique ID.
[0071]
Note that, the report triggering events described herein are defined in consideration of the application of new cell-specific offset of dynamic events. For example, you can define new events A7 and A8, which, A7 includes two entry conditions:
[0072]
Mn+Ofn+Ocn+Odn-Hys>Mp+Ofp+Ocp+Ods+Off (5)
[0073]
Mn + Ofn + Ocn-Hys> a first threshold value (6)
[0074]
Cell wherein, Mn not consider neighbor cell measurement offset, frequency specific offset of the neighbor cell frequency Ofn, Ocn static neighbor cell specific offset assigned through OAM, the present invention is introduced Odn neighboring cells special dynamic offset, Hys hysteresis parameter for the event, Mp is not considered the primary cell measurement offset, frequency Ofp dedicated frequency offset, Ocp through static assignment main OAM cell specific offset Ods introduced into the cell of the present invention serving cell specific dynamic offset, Off is the offset parameter for the event, and the first threshold value, for example, may be provided in the measconfig. In other words, when the two cell A7 event condition is satisfied, may report the cell ID, the event ID A7 and / or measurement results. Wherein the condition (6), for example, to ensure that the neighbor cell without the multi-antenna signal processing can not enjoy multi-antenna transmission quality of the transmission performance gain.
[0075]
Further, in a preferred example of the present invention it is further based on the idea of ​​arranging a departure event A7 conditions:
[0076]
Mn+Ofn+Ocn+Odn-HysMs+Ocs+Ods+Off (9)
[0080]
Mn + Ocn-Hys> second threshold (10)
[0081]
Further, in a preferred example of the present invention it is further based on the idea of ​​arranging an event out of the condition A8:
[0082]
