Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, device, terminal and base station for processing access transmission. Background Art

[0077] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0078] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present invention. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0079] In various embodiments of the present invention, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0080] Additionally, the terms "system" and "network" are often used interchangeably herein.

[0081] In the embodiments provided herein, it should be understood that "B corresponding to A" means that B is associated with A and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B based solely on A; B can also be determined based on A and / or other information.

[0082] It should be known that the motivation for designing the SSB to random access resource mapping is, first, to adapt the analog-digital hybrid array to ensure that the correct receive shaping vector is used to receive the PRACH (Physical Random Access Channel) msg1; second, to reduce the overhead of the msg2 control resource.

[0083] However, hybrid analog-digital arrays are commonly deployed in millimeter wave bands, while the mainstream deployment frequency bands are below 7 GHz, which is the centimeter wave band. In the centimeter wave band, antenna arrays are all digital, meaning that all dynamic shaping vectors are formed by digital channels (rather than analog phase shifters). In this case, the base station can completely receive the uplink signal and then perform receive beamforming. Therefore, the base station does not need to know which beam the terminal is on in advance, nor does it need to map different SSBs to different random access resources.

[0084] Regarding reducing the control resource overhead of MSG2, if the MSG2 control information requires independent control resources, it will indeed increase the control resource overhead. However, currently, a base station can configure a maximum of three CORESETs (Control Resource Sets) for a terminal. Channels that require the transmission of PDCCHs (Physical Downlink Control Channels) include: System Information Block (SIB) 1, Random Access Response (RAR), paging, and unicast PDSCH (Physical Downlink Shared Channel). Therefore, multiple channels sharing a single control resource set is unavoidable. In terms of signal properties, RAR is similar to SIB1 and paging: it is transmitted without knowing the terminal ID and has been a broadcast channel since 4G. Therefore, reusing the same control resource set for RAR, SIB1, and paging is a reasonable deployment, meaning that the same CORESET ID is simply allocated to all three channels. In this case, the full-cell scanning and sending of RAR does not increase the control resource overhead, and the data channel overhead of RAR is extremely small, only a few dozen bits. Under reasonable deployment, the full-cell broadcast of RAR does not cause a significant increase in overhead.

[0085] like Figure 1 As shown, a method for processing access transmission according to an embodiment of the present invention is applied to a terminal, including:

[0086] Step 101: Obtain configuration signaling for random access resources; wherein,

[0087] The configuration signaling is used to configure the correspondence between the synchronization signal block SSB and the random access resource, and the configuration signaling supports multiple SSBs corresponding to the same random access resource.

[0088] Here, as the configuration signaling for configuring the correspondence between SSB and random access resources, it can support multiple SSBs corresponding to the same random access resources. In this way, multiple SSBs can correspond to the same PRACH resource, instead of each SSB corresponding to a different PRACH resource, avoiding the problems of extended access delay and / or reduced access success probability.

[0089] In addition, according to at least one embodiment of the present invention, the same random access resources include: the same random access timing and the same random access sequence.

[0090] That is, when multiple SSBs correspond to the same random access resource, the random access resources corresponding to the multiple SSBs have the same random access occasion and the same random access sequence.

[0091] Of course, in this embodiment, the configuration signaling supports multiple SSBs corresponding to the same random access resource. It is not limited to the configuration signaling that can only configure multiple SSBs to correspond to the same random access resource. It can also configure other corresponding relationships between SSBs and random access resources. For example, the configuration signaling is implemented by the high layer through the parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB:

[0092]

[0093] The "ssb-perRACH-OccasionAndCB-PreamblesPerSSB" parameter applies when N is greater than or equal to 1. The first parameter is N, and the following enumerated values ​​contain possible values ​​for R. N represents the ratio of SSB to PRACH occasions, and R represents the number of sequences available in each PRACH occasion. For example, "oneEighthENUMERATED{n4,n8,n12,n16,n20,n24,n28,n32,n36,n40,n44,n48,n52,n56,n60,n64}" means N = 1 / 8, and R can be one of 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, or 64.

[0094] Of course, there may be other forms of configuring signaling, such as defining the value range of R and N, which are not listed here one by one.

[0095] In addition, according to at least one embodiment of the present invention, the configuration signaling is sent by a base station.

[0096] In addition, according to at least one embodiment of the present invention, after step 101, the method further includes:

[0097] According to the configuration signaling, random access preamble codes corresponding to multiple SSBs are sent on the first random access resource; wherein,

[0098] The first random access resource is the same random access resource corresponding to the multiple SSBs.

[0099] After obtaining the random access resource configuration signaling in step 101, the terminal using the method of the embodiment of the present invention can use the configuration signaling to send the random access preambles corresponding to multiple SSBs on the same random access resource corresponding to the multiple SSBs, i.e., the first random access resource. This allows different SSBs to be mapped to the same random access resource.

[0100] Of course, when N=1, the above steps are also applicable.

[0101] In addition, according to at least one embodiment of the present invention, the first random access resource is a random access resource that is in a first random access opportunity and corresponds to a first random access sequence.

[0102] That is, the first random access resource corresponds to the first random access opportunity and the first random access sequence. At this point, all PRACH resources are treated as a large resource pool and are no longer divided by SSB. When terminals are densely populated on a beam, all terminals share a large resource pool rather than small resource pools divided by SSBs, thereby reducing the probability of PRACH collisions. Furthermore, when terminals are densely populated on a beam, the high latency of its sub-resource pool will not cause high latency for most terminals in the cell.

[0103] In addition, according to at least one embodiment of the present invention, the first random access sequence is a random access sequence that is not allocated to non-contention access.

[0104] In addition, according to at least one embodiment of the present invention, the first random access opportunity is all valid random access opportunities in an SSB period.

[0105] Here, the valid random access opportunity is a random access occasion configured for uplink transmission. Of course, the first random access opportunity can also be a partially valid random access opportunity within an SSB period.

[0106] In this way, for N greater than 1, the terminal behavior is able to map N SS (Synchronization Signal) / PBCH (Physical Broadcast Channel) blocks to one valid prachoccasion, and in each valid prach occasion, the consecutive R contention-based preambles associated with the SS / PBCH block start from preamble index 0.

[0107] For example, Figure 2In the frame structure shown, each square represents a slot. With a 30k subcarrier spacing, a slot is 0.5 milliseconds long. If the SSB period is 20 milliseconds, a complete SSB period consists of forty slots. At the beginning of each SSB period, the base station transmits SSBs in the first four slots, two SSBs per slot, for a total of eight SSBs. Within a 20 millisecond SSB period, according to the 5 millisecond frame structure (DDDDDDDSUU), there are eight uplink slots (the background in the figure indicates the slots with diagonal lines). When N is greater than or equal to 1, the random access resources corresponding to the eight SSBs are configured using the same eight uplink slots. This means that terminals on the first beam can use all PRACH resources, terminals on the second beam can also use all PRACH resources, and so on, recursively, up to the eighth SSB. All terminals can then transmit the random access preamble on the first PRACH occasion, eliminating the need to wait, thereby reducing latency. Furthermore, since all terminals share a large PRACH resource pool, collision probability is not increased even when terminals are densely populated in a single beam.

[0108] In addition, according to at least one embodiment of the present invention, in the configuration signaling, corresponding to the case where the number of SSBs is greater than or equal to the number of first random access opportunities, the maximum value of R is the total number of random access sequences; wherein R is the number of first random access sequences at each random access opportunity.

[0109] Thus, when the number of SSBs is greater than or equal to the number of first random access opportunities, in this embodiment, the maximum value of R is determined to be the total number of random access sequences, where the total number of random access sequences is the number of all random access sequences configured in one random access opportunity.

[0110] To sum up, the method of the embodiment of the present invention configures the configuration signaling for configuring the correspondence between SSB and random access resources, and can support multiple SSBs corresponding to the same random access resources. In this way, multiple SSBs can correspond to the same PRACH resource, rather than each SSB corresponding to a different PRACH resource, thereby avoiding the problems of extended access delay and / or reduced access success probability.

[0111] like Figure 3 As shown, a method for processing access transmission according to an embodiment of the present invention is applied to a base station, including:

[0112] Step 301: Send random access resource configuration signaling; wherein,

[0113] The configuration signaling is used to configure the correspondence between the synchronization signal block SSB and the random access resource, and the configuration signaling supports multiple SSBs corresponding to the same random access resource.

[0114] The method of an embodiment of the present invention is applied to a base station. The base station can support multiple SSBs corresponding to the same random access resource by sending configuration signaling for configuring the correspondence between SSBs and random access resources. In this way, multiple SSBs can correspond to the same PRACH resource, rather than each SSB corresponding to a different PRACH resource, thereby avoiding the problems of extended access delay and / or reduced access success probability.

[0115] In addition, according to at least one embodiment of the present invention, the same random access resources include: the same random access timing and the same random access sequence.

[0116] In addition, according to at least one embodiment of the present invention, after sending the random access resource configuration signaling, the method further includes:

[0117] The receiving terminal sends a random access preamble corresponding to multiple SSBs on the first random access resource according to the configuration signaling; wherein,

[0118] The first random access resource is the same random access resource corresponding to the multiple SSBs.
