[0002]

In the future wireless communication systems, for example. 5G, the new radio (New Radio, NR) system, to support the working frequency range, and higher bandwidth in the higher operating frequency, using the beam (Beam) for data transmission, transmit gain can be obtained. For the synchronization signal (SS, synchronization signal) to the base station set transmits a synchronization signal burst cycle (e.g., SS burst set transmission cycle) to transmit to the synchronization signal block period (SS block), wherein each SS burst set comprises one or more SS burst, each SS burst comprising one or more SS block. Wherein each of the SS block may comprise a primary synchronization signal (Primary Synchronization Signal, PSS), a secondary synchronization signal (Secondary Synchronization Signal, SSS), and / or a physical broadcast channel (Physical Broadcast Channel, PBCH).

[0003]

The user equipment (user equipment, UE) during initial access to the network, the need for SS block uses a different beam transmitted by way of beam scanning (beam sweeping) is detected to obtain a downlink synchronization, by detecting the SS block to the UE confirm its position within the SS burst set, i.e. SS block index SS burst set in order to support the frame timing at the UE side.

[0004]

Further, UE only needs to detect a synchronization signal at the initial cell access achieved downlink synchronization, in order to support mobility, the UE will initial access cell (serving cell) poor signal quality in the neighbor cell search or cell of the present serving cell (Neighboring cell), and to synchronize the neighboring cell measures the reception quality of the signal, the beam quality to determine whether to perform cell handover or cell reselection. Further, if the neighboring cell carrier frequency carrier frequency different from the carrier frequency of the own cell, where the cell or present congestion, the network may schedule the UE to do inter-frequency measurement (inter-frequency). Even the signal quality of the radio access cell not present (such as the present cell is an LTE system, neighbor cell system is NR), the network may schedule the UE in the LTE work mode to measure signal quality of a neighboring cell NR , i.e. measuring different radio access (inter-RAT).

[0056]

FIG 1 is a future wireless communication network system schematic side device transmits a synchronization signal, as shown, the network side device, such as a base station transmits at least one SS block 1 is the fundamental period of the synchronizing signal to set the transmission cycle of a burst (e.g., SS burst set) shown in Figure 1, each set of synchronization signal transmission burst period may send the K SS block, wherein K is greater than or equal to 1, the frame length may be the same as a single system with other communication systems, such as 10ms, the set of bursts transmitted signal any numerical value, the length of the period may be pre-configured for such 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, etc. in the present embodiment, the number of K, single frame length system, the length of the transmission period set etc. burst signal no restrictions. In LTE, the synchronization signal is distributed transmission interval 5ms to transmit the PSS and SSS i.e. one pair intervals, but in the future wireless communication systems, such as NR, the block synchronization signal is a localized transmission, i.e. whether SS burst set What transmission cycle, it contains SS block in a time window or limit within a certain length of time (e.g., 5ms) sent, for example, shown in Figure 1, all the SS block in the SFN = after 5ms 0 transmission (SFN, system frame number, a system frame number) within a time window. Thus, unlike the LTE, the UE using the search 5ms can capture the synchronization signal for NR, SS block when the UE detects, since the UE can not determine the transmission time window of the specific location of the SS block, but to use SS burst set period search, i.e., in addition to sending SS block time window, the UE at other times SS burst set transmission period can not be detected SS block. Further, in addition to some cases, the network side will notify the UE measures specified outer cells, usually UE can not know which neighbor cell configuration information, such as information related to the SS. Further, the base station serving the neighbor cell is difficult to predict what the UE, UE needed by the neighboring cell search to detect a neighbor cell of the SS, and then obtain the neighboring cell synchronization information ID. Since future wireless communication systems, supports a variety of SS burst set transmission period, e.g. 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, etc., may be used with the cells neighboring the serving cell of a different SS burst set transmission period, since the UE can not know in advance information of the neighboring cell SS, i.e., the time window can not know the specific location of the transmitting SS Block, and therefore, when the UE detection of Block SS, only search by maximum SS burst set period, such as 160ms to search. This will cause an increase in the time of UE cell search and measurement, as well as increased UE power consumption, which led UE can not be completed quickly switch, even communication is interrupted.

[0057]

Typically, the network side configures a user equipment radio resource management (RRM, radio resource management) parameters associated with a set of measurements, for example, the parameter may be the start position of the measuring window, the window length of the measurement, the measuring window period, SS burst set period and the like, the type of measurement can be divided into intra-frequency measurement connected state (intra-frequency cONNECTED mode measurement), a connected state inter-frequency measurement (inter-frequency cONNECTED mode measurements), measuring an idle state (iDLE mode measurements), since the future the wireless communication system supports multiple SS burst set the transmission cycle, and therefore, needs to be designed to position the time window of the transmission SS block.

[0058]

To solve the above problems, the present embodiment proposes a method of transmitting a signal, the detection method and apparatus, a communication system, by the network side and the user side position Block SS transmits a predefined time window, or configured by the network side sending SS the position of the time window block, such that the UE performs the SS block detected within a time window of predetermined positions, thereby reducing the UE cell search and measurement time, reduce the complexity of the processing at the UE, the UE reduces power consumption, contributes to UE fast switching implemented to solve the existing problems.

[0059]

[0063]

Step 301, the time window within a predetermined position within the block sync signal transmission period on the user side transmits a synchronization signal blocks (SS block).

[0064]

Thus, for any transmission cycle sync blocks, a standard pre-defined position of the transmission time window SS block, i.e. the network side and the user side in advance knows where to send the synchronization signal block, so that the UE can time window the predetermined position in SS block for the detection, thereby reducing the UE cell search and measurement time, reduce the complexity of the UE-side processing and reduce the power consumption of the UE, accelerated cell switching, avoiding interruption of communication, to solve the existing problems.

[0065]

In the present embodiment, the block sync signal transmission period may be a set of burst synchronization signal (SS burst set) transmission cycle, or may be a predetermined time interval length. Wherein the one or more SS block constituting a set, to the transmission cycle or period of transmission time intervals.

[0066]

In the present embodiment, the synchronization signal block transmission period may be pre-configured by the network side, e.g., the length of the synchronizing signal block transmission period (SS burst set transmission period) may be predetermined to any value, such as 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, etc., in the system, NR, SS burst set to default transmission cycle 20ms.

[0067]

In the present embodiment, the time window represents a time range, all the SS block in the block sync signal transmission period can be transmitted in this time range. The range is less than equal to the synchronization signal block transmission period, or may be the same as the minimum block sync signal transmission period, e.g., the block sync signal transmission period is a transmission period SS burst set, for example, the transmission period may be 5ms, 10ms , 20ms, isochronous 40ms, 80ms or 160ms, the SS block may be transmitted all within a time window of a 5ms.

[0068]

[0069]

FIG 2 is a diagram showing a block configuration of the synchronization signal, as shown in FIG. 2, SS block may comprise a PSS / NR-PSS, 1 th SSS / NR-SSS, but can also comprise two PBCH / NR-PBCH symbol. The structure of the block synchronization signal is not limited to the configuration shown in FIG. 2, other configurations may be employed, such as other arrangements, it may further comprise a reference signal or the like, for example, according to NR-PSS, NR-PBCH, NR-SSS, NR-PBCH order, arranged in the SS block, the present embodiment is not limited thereto.

[0070]

In the present embodiment, in each transmission cycle sync blocks, the number of SS block actually transmitted can be determined, the determination is not limited in the way. Wherein, the maximum block number of the SS can determine the carrier frequency, e.g., when the carrier frequency is less than 3GHz, SS is the maximum number of block 4, the carrier frequency and less than or equal to 3GHz 6GHz, the maximum block number of SS 8, when the carrier frequency and less than or equal to 6GHz 52.6GHz, the maximum number of SS block 64.

[0071]

In the present embodiment, for a different transmission cycle sync blocks, you may be predefined each synchronization signal block transmission period (e.g. SS burst set transmission period) corresponding relationship and the corresponding predetermined position, and stored in a network side and user side, when determining a sync signal block transmission period, when within a time window of predetermined positions in the sync signal block transmission period of the user-side transmission SS block; user side may determine the time window of the predetermined positions based on the correspondence relationship, and in that SS block detecting a predetermined position within a time window. Wherein, when the user is previously known sync signal block transmission period, the user side according to the correspondence directly detect SS block within a time window of predetermined positions on should period, when the user side does not know the synchronization signal block transmission period, the user-side SS block according to the corresponding relation between the detected within a time window corresponding to a predetermined position of each possible period.

[0072]

In the present embodiment, the pre-defined time window position (predetermined position) within the block sync signal transmission period, wherein the predetermined location comprises a start position and end position of the time window in the transmission block period of the synchronizing signal.

[0073]

Wherein the predetermined position of the block sync signal transmission period of the same length may be the same or different; e.g., the predetermined position may be predefined or a plurality of time windows, when one block of the same sync signal transmission period length at the predetermined position same predetermined position, such that the UE SS block detected within a time window of the same predetermined location, whereby the UE is reduced and the cell search time measurement. When a plurality of the predetermined location, the network side may select a predetermined position or predetermined positions selected in accordance with the predetermined rule, and transmits the SS block within a time window of the predetermined location, the network side may send indication information to the UE notifies the UE side the use of which a predetermined position, or the UE side determines the network side select which one predetermined position in accordance with a predetermined rule, so that the UE SS block is detected within a time window of the predetermined position, or the UE side at all possible predetermined positions SS block were detected within the time window.

[0074]

Wherein, when the number of measurements related to the carrier frequency is more than one, each of the carrier frequencies can support a predetermined number of sync blocks signal transmission period, wherein the sync signal transmission period for one block of a carrier frequency, the transmission cycle of the synchronizing signal block the same predetermined position.

[0075]

Wherein, at a predetermined position-synchronization signal block transmission period of different lengths corresponding to, at least one common predetermined position; i.e. sync signal blocks of equal length transmission cycle transmits a predetermined position of the time window SS block alignment, synchronization of different lengths signal block transmission period, at least a predetermined position of a transmission time window SS block is aligned, and the predetermined position is predefined. For example, the common predetermined position may be determined according to the position of the transmission SS block maximum sync signal block transmission period of the time window, i.e., other synchronization signal block transmission cycle there is a time window of maximum sync signal block a transmission SS block transmission SS block aligned transmission time window period.

[0076]

Wherein, when the number of measurements related to the carrier frequency is more than one, each of the carrier frequencies can support a predetermined number of sync blocks signal transmission period, which may be supported for a carrier frequency synchronization signal blocks of different lengths of the transmission cycle, at least a common predetermined position; synchronizing signal blocks of different lengths i.e. the transmission cycle at least a predetermined position of a transmission time window SS block is aligned, and the predetermined position is predefined.

[0077]

Wherein, when the number of measurements related to the carrier frequency is more than one, each of the carrier frequencies can support a predetermined number of sync blocks signal transmission period, wherein the sync signal transmission period for blocks of different lengths may be supported by different carrier frequencies, at least a common predetermined location; i.e., different carrier frequencies of the transmission cycle of the synchronization signal blocks of different lengths in a predetermined position of at least one transmission time window SS block is aligned, and the predetermined position is predefined.

[0078]

For example, the predetermined position is a common SFN_cw, SFN_cw = x + Sp_m · n, wherein, x is the initial position of the block sync signal transmission period, x = 0,1, ... Sp_m-1, Sp_m = Max {SS_period_i / 10ms , i = 1, ..., N}, SS_period_i length of one or more carrier frequencies may support sync signal transmission period, N is the number of more than one carrier frequency can support transmission period, n is the index of the common predetermined position.

[0079]

In one embodiment, the block synchronization signal in the transmission period, the start position of the predetermined position is a start position of the block sync signal transmission period, or a sync signal from the block start position every transmission period of the time window length position, the end position of the predetermined position is a position spaced the length of the time window starting position, i.e., when the block sync signal transmission period is Nms, the length of the time window is Mms, the predetermined initial position the location may be Nms 0ms, Mms, 2Mms, 3Mms, ..., (L) Mms at the end position of the predetermined location may be the Nms Mms, 2Mms, 3Mms ..., (L + 1) Mms place. For example, when the block sync signal transmission period (e.g. SS burst set transmission cycle) is 20ms, the length of the time window is 5ms, i.e. half of the frame length, the start position of the predetermined positions may be 0,5ms, 10ms, 15ms, the end position of the predetermined positions may be 5ms, 10ms, 15ms, 20ms, the time that is a predetermined position of the window may be 0-5ms, 5ms-10ms, 10ms-15ms or 15ms-20ms. However, the present embodiment is not limited thereto, the start position of the predetermined position may be the length of the time window intervals of an arbitrary position in the transmission block period signal from the sync position, for example, the arbitrary position Pms, the starting position may be a predetermined position in Nms Pms, P + Mms, P + 2Mms, P + 3Mms the like, the end position of the predetermined positions may be Nms the P + Mms, P + 2Mms, P + 3Mms office and so on, not bore you with here.

[0080]

In one embodiment, the block synchronization signal in the transmission period, the predetermined position is a synchronization signal from the blocks of each frame or a forward position rearward position, for example, the first half frame or half frame of one frame, e.g. the frame may be a start frame, the frame may be other except for the starting frame.

[0081]

For example, the length of the time window is 5ms, the transmission period is longer than the length of the time window, i.e. 10ms, 20ms, 40ms, 80ms, 160ms when the predetermined position may be 10ms, 20ms, 40ms, 80ms, 160ms per the first half frame or half frame frames, i.e. transmission cycle is 10ms, the predetermined location may be a half-frame front half frame or after the transmission cycle is 20ms, the predetermined location may be four, it is located in each frame a first half-frame or half-frame, the transmission cycle is 40ms, the predetermined location may be 8, located half frame front half frame or each frame, the transmission cycle is 80ms, the predetermined location may be 16, which are located when the first half frame or half-frame of each frame, the transmission period is 160ms, the predetermined location may be 32, are located in the front half-frame of each frame or half frame after. A possible candidate position above a predetermined position, the predetermined position may be one or more of the candidate positions. Similarly, to the common position of the predetermined transmission period of the synchronization signal different blocks it may be located within one or more of said candidate positions.

[0082]

Wherein the transmission period is 10ms, 20ms, 40ms, 80ms, 160ms or time, which may be a predetermined position, i.e., the first half-frame start frame field 5ms-10ms 0ms-5ms or after, but in the present embodiment is not this way of limitation, the start position of the predetermined position may be spaced from the start frame Pms position, the end position of the position Pms + the length of the time window, i.e., P = 1, the predetermined location may be 1ms-6ms and the like, where not bore above purely as an example the starting frame of the predetermined position, the predetermined position of the other embodiment for frame start frame the same as the embodiment, will not be repeated here.

[0083]

Wherein, the same, the same as the predetermined position in the transmission period and the transmission period length of the time window.

[0084]

In the present embodiment, there is a system frame number (SFN, system frame number) deviation serving cell and neighboring cells, in order to make the cell transmission time window between the SS block alignment, the method may further comprise (as shown): the system frame number offset pre-defined according to the predetermined position, i.e., when the predetermined position previously defined, to consider this factor SFN deviation can be corrected (compensated) by which the deviation SFN predetermined position, in order to ensure inter-cell transmission of the SS block time window alignment.

[0085]
