Description

Method and related device for sending SSB

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and a related apparatus for sending a synchronization signal and a PBCH block SSB.

Background

In current communication systems, a user equipment searches for a Synchronization Signal Block (SSB) transmitted by a base station to perform cell search, synchronization, and measurement for accessing a network. In general, the base station transmits the SSB at a period of 20 ms. However, in a cell light, no-load scenario, the message broadcasting the SSB occupies too much channel resources (e.g., 8%). For this reason, the base station may also transmit the SSB at a period of 40/80/160 ms to reduce channel resources consumed by the base station.

However, in a scenario of a Stand Alone (SA), the user equipment needs to use an SSB measurement to assist Tracking Reference Signal (TRS) measurement, and if the base station lengthens a period of the SSB, a time bias anomaly may be generated, which may cause a call drop of the user equipment on the network or a new user equipment cannot enter the network.

The system architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

Please refer to fig. 1-1, which is a schematic diagram illustrating a structure of a communication system according to an embodiment of the present application. The embodiment of the present application provides a communication system 100, which includes a base station 110 and a user equipment 120.

The user device 120 may include any terminal device such as a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), a POS (Point of Sales), and a vehicle-mounted computer.

Taking a mobile phone as an example, fig. 1-2 are block diagrams illustrating a part of structures of a mobile phone related to a terminal provided in an embodiment of the present application. Referring to fig. 1-2, a handset includes: radio Frequency (RF) circuitry 1110, memory 1120, input unit 1130, display unit 1140, sensors 1150, audio circuitry 1160, wireless fidelity (WiFi) module 1170, processor 1180, and power supply 1190. Those skilled in the art will appreciate that the handset configuration shown in fig. 1-2 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

In some possible implementations, the base station 110 may be a gNB in a 5G radio access network (NG-RAN). As shown in fig. 1-3, the 5G network architecture includes a 5G access network (NG-RAN) and a 5G core network (5 GC), where the 5G radio access network includes two nodes: gNB and ng-eNB.

Wherein the gNB application provides the user equipment 120 with nodes of protocol terminals of a user plane and a control plane of the NR, and is connected to the 5GC via the NG interface. The NG-eNB applies a node of a protocol terminal providing a user plane and a control plane of the E-UTRA to the user equipment 120 and is connected to the 5GC via the NG interface. Therefore, the gNB is required for independent networking, and the ng-eNB is configured for a different core network in order to be downward compatible with the 4G network.

As shown in fig. 1 to 3, the network element related to the present application is a gNB, and the gNB relates to the functions of the 5G network as shown in fig. 1 to 4, and the specific contents of the functions are related to the prior art and are not described herein again.

In the current communication system, the user equipment 120 searches for the SSB transmitted by the base station 110 for cell search, synchronization, and measurement to access the network. In general, the base station 110 transmits the SSB at a period of 20 ms. However, in a cell light, no-load scenario, the message broadcasting the SSB occupies too much channel resources (e.g., 8%). For this reason, the base station 110 may also transmit the SSB at a period of 40/80/160 ms to reduce the channel resources consumed by the base station. For example, as shown in fig. 1-5, in a light-load and no-load cell scenario, the SSB period of the original 20 ms duration is extended to 160 ms. In the scenario of Stand Alone (SA), the ue 120 needs to use the SSB measurement to assist Tracking Reference Signal (TRS) measurement, and if the base station 110 lengthens the SSB period, a time bias anomaly may be generated, which may cause the ue 120 on the network to start dropping in the second 20 ms period, or a new ue 120 cannot enter the network.

The foregoing embodiment describes the communication system 100 provided by the present application, and next, a communication method performed based on the communication system 100 is described by

embodiments

1 and 2.

Examples 1,

Referring to fig. 2-1, a method for sending an SSB according to an embodiment of the present disclosure mainly includes the following steps:

201. the base station determines a full period, wherein the full period comprises N synchronous periods, and N is an integer greater than or equal to 2.

In this embodiment, the base station may set a full period, and send a full SSB once per full period. It should be noted that one full period includes N synchronization periods, where each synchronization period is one synchronization period. In some possible implementations, the duration of the synchronization period is 20 milliseconds, and the duration of the full number of periods may be 40/80/160 milliseconds.

For example, if the full period is 40 ms and the sync period is 20 ms, then one full period includes 2 (40 ms/20 ms) sync periods; if the full period is 80 ms and the sync period is 20 ms, then one full period comprises 4 (80 ms/20 ms) sync periods; if the full period is 160 ms and the sync period is 20 ms, then one full period includes 8 (160 ms/20 ms) sync periods.

Illustratively, as shown in fig. 2-2, the duration of the full-scale period is 80 ms and the duration of the synchronization period is 20 ms, so that the full-scale period includes 4 synchronization periods, respectively, which are 0/1/2/3 of the synchronization period.

202. The base station determines a first synchronization period, the first synchronization period being one of the N synchronization periods, the first synchronization period being for transmitting a full SSB on a first beam.

In this embodiment, after the base station determines the full amount period, the base station may determine, from the N synchronization periods, a first synchronization period corresponding to the first beam, where the first synchronization period is used to transmit the full amount SSB through the first beam. For example, as shown in fig. 2-2, the base station may randomly determine a synchronization period of 0 as the first synchronization period. In some possible implementations, the base station may also determine more than one synchronization period as the first synchronization period. For example, the base station determines a synchronization period of 0/1/2, or a synchronization period of 0/1/3, or a synchronization period of 0/2/3, or a synchronization period of 1/2/3, or a synchronization period of 0/1, or a synchronization period of 0/2, or a synchronization period of 0/3, or a synchronization period of 1/2, or a synchronization period of 1/3, or a synchronization period of 2/3 as the first synchronization period.

203. The base station determines a second synchronization period, which is one of the N synchronization periods, and the second synchronization period is used for transmitting the synchronization SSB in the first beam.

In some possible implementations, after the base station determines the first synchronization period, a second synchronization period for transmitting the synchronization SSB through the first beam may be further determined, where the second synchronization period is a synchronization period different from the first synchronization period among the N synchronization periods.

For example, as shown in fig. 2-2, the base station may randomly determine a synchronization period of 0 as the first synchronization period, and then the base station may further determine any 1 of 1/2/3 of the synchronization periods as the second synchronization period. In some possible implementations, the base station may determine two of the synchronization periods 1/2/3 as 2 synchronization periods, respectively, which is not limited herein. In some possible implementations, the base station may determine the synchronization periods 1/2/3 as 3 synchronization periods, respectively, which is not limited herein.

204. The base station transmits the full SSB through the first beam for a first synchronization period.

In the embodiment of the present application, after the base station determines the first synchronization period, the full SSB may be transmitted in the first synchronization period.

As shown in fig. 2-3, the full SSB is composed of three parts, namely, primary Synchronization Signals (PSS), secondary Synchronization Signals (SSS), and a Physical Broadcast Channel (PBCH). The full SSB occupies 4 Orthogonal Frequency Division Multiplexing (OFDM) symbols in the time domain, and occupies 240 subcarriers in the frequency domain, which are numbered 0 to 239. The PSS is located in the middle 127 subcarriers of symbol 0, the SSS is located in the middle 127 subcarriers of symbol 2, and different subcarriers are respectively located at two ends for protecting the PSS and the SSS. In addition, PBCH is located at symbol 1/3 and symbol 2, wherein symbol 1/3 occupies all subcarriers from 0 to 239, and symbol 2 occupies all subcarriers except subcarriers occupied by SSS and subcarriers protecting SSS.

Wherein, the PSS, SSS, PBCH occupy different symbols and occupy resources as shown in fig. 2-4: protocol 38.211Table 7.4.3.1-1. Where k and l denote the frequency domain index and the time domain index within the SSB, respectively, and Set 0 denotes that the RE of the portion in the protocol 38.211table 7.4.3.1-1 is assumed to be Set to 0 by the user equipment.

It should be noted that, because the PBCH carries the system broadcast message, the user equipment does not need to retrieve in each synchronization period, but only needs to retrieve in at least one synchronization period.

It should be noted that, in the fifth generation mobile communication technology (5 th generation mobile communication technology,5 g), a super-large-scale antenna array is introduced, wherein the number of the millimeter wave frequency band antennas may be as high as 256. The application of beamforming in 5G can make the signal energy more concentrated and enhance the coverage through beamforming, and reduce the interference between users and cells. Through the SSB beam scanning, a proper beam direction pair is established between the base station and the ue for subsequent access and data transmission and synchronization. In particular, SSB beam scanning may be transmitted via different beams at different times in a time division manner, as shown in fig. 2-5. In the SSB beam scanning process, the user equipment selects the beam with the largest signal strength as the initial beam direction, and performs subsequent processing. For example, as shown in fig. 2-6, user equipment 1 receives the greatest signal strength from beam 3, while user equipment 2 receives the greatest signal strength from beam 7.

When the wave with the maximum signal strength is searched, the ue transmits access information of a Physical Random Access Channel (PRACH) at a time associated with the index of the selected SSB. The base station can judge the direction of the terminal and establish an initial beam pair by analyzing the received access information of the PRACH.

205. The base station transmits the first synchronization SSB through the first beam during the second synchronization period.

In the embodiment of the present application, after the base station determines the second synchronization period, the synchronization SSB may be sent in the second synchronization period. Specifically, as shown in fig. 2-7, the base station transmits the full SSB through the first beam in synchronization period 0, and transmits the synchronization SSB through the first beam in synchronization period 1/2/3, for example, transmits the first synchronization SSB in synchronization period 1. It should be noted that, as shown in fig. 2-8, the synchronous SSB includes SSS and PSS, but not PBCH, compared to the full SSB.

In some possible implementations, the base station may transmit multiple beams simultaneously. In order to avoid that the full SSBs are simultaneously transmitted in different beams, which results in excessive resource occupation in the synchronization period, the full SSBs on different beams may be transmitted in different synchronization periods in the full period, respectively. Exemplarily, it can be realized by embodiment 2.

Examples 2,

Referring to fig. 3-1, a method for sending an SSB according to an embodiment of the present application mainly includes the following steps:

301. the base station determines a full period, wherein the full period comprises N synchronous periods, and N is an integer greater than or equal to 2.

Please refer to step 201, which is not described herein.

302. The base station determines a first beam in a first synchronization period that transmits a full amount of SSBs, the first synchronization period being one of the N synchronization periods.

For example, assuming that the existing system has a plurality of beams, for example, 4/8/16 beams, as shown in fig. 3-2, taking 4 beams as an example, which are beams 0/1/2/3, respectively, the base station determines beam 0 that transmits the entire amount of SSBs in synchronization period 0. In some possible implementations, the base station may randomly select from 4 beams, here, beam 0 is taken as an example. In this embodiment, after the base station determines that the beam 0 is the first beam for transmitting the full SSB in the first synchronization period, in order to avoid excessive resource occupation in the synchronization period due to the fact that the full SSB is simultaneously transmitted in different beams, the base station simultaneously determines that the beam 1/2/3 is the beam for transmitting the synchronization SSB in the first synchronization period.

303. The base station determines a second beam in the second synchronization period that transmits the full amount of SSBs.

In the embodiment of the present application, as shown in fig. 3-2, after the base station determines that beam 0 of the full SSB is transmitted in synchronization period 0, in the second synchronization period, the base station may select one beam from the remaining beams 1/2/3 as the second beam of synchronization period 1. In addition, in order to avoid simultaneously transmitting the full amount of SSBs in different beams, which results in excessive resource occupation in the synchronization period, the base station simultaneously determines that the beam 2/3 is the beam transmitting the synchronization SSB in the second synchronization period. Similarly, the base station can select one beam from the remaining beams 2/3 as the third beam of sync period 2, and finally the remaining beam 3 as the fourth beam of sync period 3.

304. The base station transmits the full SSB through the first beam for the first synchronization period and transmits the second synchronization SSB through the second beam for the first synchronization period.

In this embodiment, after determining that the first beam of the full SSB is sent in the first synchronization period, the base station may send the full SSB through the first beam in the first synchronization period, and send the second synchronization SSB through the second beam in the first synchronization period. For example, as shown in fig. 3-2, when the base station transmits the full amount of SSB through beam 0 in synchronization period 0, in order to avoid simultaneously transmitting the full amount of SSB in different beams, which would result in excessive resource occupation in the synchronization period, the base station simultaneously transmits the synchronization SSB (i.e., the second synchronization SSB) through beam 1/2/3 in synchronization period 0.

305. The base station transmits the first synchronization SSB through the first beam for a second synchronization period and transmits the full SSB through the second beam for the second synchronization period.

In this embodiment, after the base station determines that the second beam of the full SSB is transmitted in the second synchronization period, the full SSB may be transmitted through the second beam in the second synchronization period. For example, as shown in fig. 3-2, the base station transmits the full SSB through the second beam in synchronization period 1 and transmits the synchronization SSB through beams 0/2/3 in synchronization period 0/2/3.

Note that compared to the full SSB, the synchronous SSB includes SSS and PSS, but not PBCH.
