Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, in particular to a signal sending and receiving method, network device and terminal. BACKGROUND

[0002] Distributed super large scale antenna system presents the significant characteristics of more antennas, wider geographical distribution, and deeper wisdom cooperation. Distributed super large scale antenna system is composed of a large number of distributed sites in different geographical locations to form a distributed cooperative cluster. The information such as interactive scheduling between the cooperative multi-sites is exchanged, and the process such as resource scheduling and joint data transmission is completed cooperatively. Through wisdom interaction and intelligent cooperation, on the one hand, interference is effectively eliminated, and signal reception quality is enhanced; on the other hand, coverage is effectively enhanced, and user boundary feeling is eliminated.

[0003] The workflow of the existing distributed system on the protocol is that after the terminal accesses the network, the quality of the adjacent cell or TRP (transmission and reception point) is measured, and the measurement result is reported to select the appropriate TRP for cooperative transmission. However, in the actual scene, a more static method is adopted, that is, the cooperative base station / RRU (radio frequency remote unit) is selected during deployment, and a cell configuration is directly performed for cooperative transmission.

[0004] In the high-capacity hotspot area, high-low frequency cooperative deployment can meet the capacity demand of the hotspot area as much as possible on the basis of ensuring coverage. The coverage range of the high-frequency site is small, but the capacity in a small range can be greatly improved, so distributed deployment in a certain range is also a typical demand and scene of high-frequency deployment.

[0005] In the distributed transmission in the high-low frequency cooperative network, the terminal needs to access the primary carrier of the primary cell, measure the quality of the adjacent cell or TRP and report it, and then the primary cell reconfigures to add a high-frequency secondary cell. The terminal first receives the SSB (synchronization signal) on the primary carrier of the secondary cell, completes the downlink time synchronization, reads the MIB (master information block) message, and then performs random access to complete the secondary cell addition and establish the RRC connection. Subsequently, based on the measurement result of the high-frequency band, the appropriate TRP is selected for cooperative transmission.

[0006] In the prior art, for the cooperative system, the SSB (synchronization signal block) sent by each TRP may have different cases, some SSBs correspond to cooperative cells, and some SSBs correspond to non-cooperative cells. Therefore, how to notify this SSB pattern and how to bind it with the physical random access channel PRACH resource need to be redesigned. SUMMARY

[0007] The application provides a signal sending and receiving method, a network device and a terminal, which are used for ensuring that a terminal correctly performs rate matching and ensuring that random access resource association is only related to a SSB of a cell; in a cooperative access system, resource waste is avoided, and random access latency is effectively reduced.

[0046] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0047] like Figure 1 As shown, the synchronization signals in the system are divided into two categories: one is ordinary non-cooperative synchronization signals, in which each TRP independently sends synchronization signals at the location of such synchronization signals; the other is cooperative synchronization signals, in which different TRPs can cooperate to send synchronization signals at the location of such synchronization signals, so that the terminal can measure the information of the cooperating cell during the synchronization phase, thereby starting cooperative transmission during the access phase, achieving reduced latency and improved access process speed or enhanced reliability.

[0048] Based on the above-described method of transmitting synchronization signals, embodiments of the present invention propose a configuration scheme for random access resources in this cooperative synchronization signal transmission system:

[0049] like Figure 2 As shown, in the current NR random access resource configuration, the network side first configures periodically occurring random access resources, and then performs association mapping on the configured random access resources according to the SSB pattern actually transmitted in the current cell as indicated in the system information, thereby determining the random access resource associated with each SSB so that the terminal can perform random access on its selected SSB.

[0050] But since this scheme is designed for non-cooperative system, where the actual transmitted SSB pattern is configured to inform the terminal which resource in this cell is periodically occupied by SSB, if directly applied to cooperative system, since the SSB sent by each TRP may be different, some SSB corresponds to cooperative cell, and some SSB corresponds to non-cooperative cell, how to inform this SSB pattern, how to bind with PRACH resource, need to be redesigned.

[0051] The actual transmitted SSB pattern (synchronization signal transmission pattern) of the cell is to inform the terminal of the periodically transmitted SSB (synchronization signal) in the current cell, so that the terminal can perform rate matching when receiving signals to avoid these periodically occupied resources.

[0052] In the cooperative system, according to this goal, the actual transmitted SSB pattern configured by the system should be considered from the perspective of the sending node, rather than from the perspective of the cell. Specifically, each SSB corresponds to the indication in the system message that all SSB positions sent by all TRPs that cooperatively send the SSB at this SSB position.

[0053] Specifically, as shown in Figure 3 For SSB1, only one TRP participates in sending at this position, according to the existing scheme, the system will only indicate the first four SSB positions as the actually transmitted SSB, i.e. 11110000, but in the cooperative system, this TRP will also send SSB corresponding to other cell IDs (cell positioning) at other positions, so these also need to be indicated, i.e. as shown in Figure 3 For SSB1, the actual indicated pattern should be 11111101.

[0054] For cooperative SSB4, the actual indicated pattern should be 11111111, and for cooperative SSB6, the actual indicated pattern is 11011010.

[0055] As can be seen, the SSB positions indicated by this SSB pattern cover multiple SSBs under different cell IDs. However, according to the current protocol configuration, the terminal will perform association mapping on the PRACH resource according to this SSB pattern. But under this indication method, it will cause the association period of PRACH to be very large, and the terminal will not send PRACH on the resource corresponding to other cell IDs, resulting in resource waste.

[0056] The system needs to reconfigure the SSB pattern actually used for PRACH resource association, or make a further indication on the existing SSB pattern, that is, the terminal needs to acquire another set of SSB resources for PRACH resource association.

[0057] As Figure 4 Embodiments of the present application provide a signal sending method applied to a network device, and the method comprises the following steps of:

[0058] 41: configuring a first synchronization signal and a second synchronization signal, the first synchronization signal being used for instructing a terminal to perform rate matching according to an indicated resource, and the second synchronization signal being used for instructing the terminal to perform PRACH resource association according to an indicated resource, the resource indicated by the second synchronization signal being a subset or a whole set of the resource indicated by the first synchronization signal.

[0059] Here, the configuring the first synchronization signal and the second synchronization signal can specifically include the following steps of:

[0060] For a first type of cell, a first synchronization signal is configured.

[0061] For a second type of cell, a first synchronization signal and a second synchronization signal are configured.

[0062] Optionally, the configuring the first synchronization signal comprises configuring a first synchronization signal transmission pattern, and the configuring the second synchronization signal comprises configuring a second synchronization signal transmission pattern.

[0063] As an implementation manner, for the first type of cell, a first synchronization signal transmission pattern can be configured to instruct the terminal to perform rate matching according to an indicated resource.

[0064] For the second type of cell, a first synchronization signal transmission pattern and a second synchronization signal transmission pattern are configured, the first synchronization signal transmission pattern being used for instructing the terminal to perform rate matching according to an indicated resource, and the second synchronization signal transmission pattern being used for instructing the terminal to perform PRACH resource association according to an indicated resource, the resource indicated by the second synchronization signal transmission pattern being a subset or a whole set of the resource indicated by the first synchronization signal transmission pattern.

[0065] In this embodiment of the present application, a base station configures two sets of SSB patterns, one set being used for rate matching and the other set being used for PRACH association. This ensures that the terminal correctly performs rate matching and also ensures that the random access resource association is only related to the SSB of the cell; in a cooperative access system, resource waste is avoided, and the random access delay is effectively reduced.

[0066] In an optional embodiment of the present application, the first type of cell corresponds to a first type of cell ID; and the second type of cell corresponds to a second type of cell ID.

[0067] In an optional embodiment of the present application, the first synchronization signal transmission pattern or the second synchronization signal transmission pattern is a transmission pattern of synchronization signals in a synchronization signal group.

[0068] In an optional embodiment of the present application, the second synchronization signal is indicated only for resources indicated by the first synchronization signal or is indicated only for resources indicated by a synchronization signal in a group.

[0069] As shown in Figure 3 , for each SSB, two sets of SSB patterns need to be indicated, one set is used for rate matching SSB position, and one set is used for PRACH resource configuration SSB position. For high frequency, the overhead is very large, such as 64+64 bits are needed to completely indicate the bitmap information. On this basis, some indication methods to reduce the overhead can be considered:

[0070] Method one: different configuration methods are used for cooperative cells and non-cooperative cells. In order to enable the terminal to distinguish between cooperative cells and non-cooperative cells during cell search, through the agreement of the protocol, the terminal can determine the possible positions of cooperative cells and non-cooperative SSBs when searching, so as to select different SSB sequences for detection. With this assumption, the SSB pattern of non-cooperative cells can be further described as follows:

[0071] For example, for SSB1 in Figure 3 , according to the agreement, the first four SSBs are non-cooperative SSBs. In this case, the SSB pattern indicated by the first four bits in the rate matching SSB pattern is actually the SSB that can be used for PRACH association. In this way, no additional SSB configuration is needed, thereby saving the overhead.

[0072] For cooperative cells, the SSB pattern used for PRACH association under the current cell ID still needs to be configured additionally.

[0073] In order to save the overhead, further indication can be considered only for the SSB corresponding to "1" indicated in the rate matching SSB pattern. For example, for SSB6 in Figure 3 , the rate matching SSB pattern is 11011010, and when indicating the SSB for PRACH, 00001 is indicated, reducing the number of bits by 3.

[0074] Method two: there are 64 SSB positions in high frequency in the system, if the above method is used, the reduction of the number of bits is still limited, therefore, a grouping indication method is used to control the overhead, such as equally dividing the 64 SSB positions into 8 groups, first using 8 bits to indicate whether there is SSB transmission in the 8 groups, and then using 8 bits to indicate the SSB transmission in the 8 positions in a group, in this way, only 8 bits or less bits are needed to indicate the SSB that can be used for PRACH association in a group.

[0075] The above embodiments of the application can ensure that the terminal correctly performs rate matching by indicating two sets of SSB patterns, and can ensure that the random access resource association is only related to the SSB of the current cell, thereby avoiding resource waste in the cooperative access system and effectively reducing the random access delay.

[0076] As shown in Figure 5 The embodiments of the application also provide a signal receiving method applied to a terminal, and the method comprises the following steps:

[0077] 51: The terminal performs rate matching according to the resource indicated by the first synchronization signal, and performs PRACH resource association according to the resource indicated by the second synchronization signal, wherein the resource indicated by the second synchronization signal is a subset or the whole set of the resource indicated by the first synchronization signal.

[0078] Here, the terminal performs rate matching according to the resource indicated by the first synchronization signal, and performs PRACH resource association according to the resource indicated by the second synchronization signal, and the specific process is as follows:

[0079] For the first type of cell, the terminal performs rate matching according to the resource indicated by the first synchronization signal.

[0080] For the second type of cell, the terminal performs rate matching according to the resource indicated by the first synchronization signal, and performs PRACH resource association according to the resource indicated by the second synchronization signal transmission pattern.

[0081] Optionally, for the first type of cell, the terminal performs rate matching according to the resource indicated by the first synchronization signal transmission pattern; and for the second type of cell, the terminal performs rate matching according to the resource indicated by the first synchronization signal transmission pattern, and performs PRACH resource association according to the resource indicated by the second synchronization signal transmission pattern.
