Referring to fig. 2, fig. 2 is a flow chart of a signal transmission method according to an embodiment of the application. The signal transmission method may be performed by a terminal device. The signal transmission method comprises the following steps:
s101, the terminal equipment determines N1 reference signals with reference signal received power RSRP larger than a preset value from a plurality of reference signals, wherein N1 is an integer larger than or equal to 0. The reference signal may be a synchronization signal block (synchronization signal block, SSB) or a channel state information reference signal (channel state information reference signal, CSI-RS). Optionally, the reference signal is configured by the network side through higher layer signaling, and may be a downlink reference signal for associating Msg1 transmission.
S102, terminal equipment respectively sends random access messages on M repeated transmission resources, beams adopted for sending the random access messages on each repeated transmission resource are determined based on N1 beams associated with N1 reference signals, and M is an integer larger than 0.
Wherein the beam associated with the reference signal is a beam, such as a receiving beam, used by the terminal device to receive the reference signal. The preset value may be configured by the network device through higher layer signaling, or may be predefined.
In addition, the value of M is equal to the number of repeated transmissions of the random access message. Then, the terminal device may repeat the transmission of the random access message M times, each time the random access message is transmitted on one of the M repeated transmission resources. Wherein the repeated transmission resource may be a random access opportunity (random access channel occasion, RO). The terminal device repeatedly sends the random access message M times may correspond to a retransmission resource set H, where the retransmission resource set H includes M elements, for example, the retransmission resource set H is { H1, H2, …, HM }, where each element corresponds to one retransmission resource of the M retransmission resources.
In addition, the value of M and/or the repeated transmission resources used by the terminal device each time the terminal device sends a random access message may be indicated to the terminal device by higher layer signaling or dynamic signaling. For example, the higher layer signaling may be radio resource control (Radio Resource Control, RRC) signaling, and the dynamic signaling may be medium access control-element (medium access control-control element) information or downlink control information (downlink control information, DCI).
The determining manner of the beam used by the terminal device to transmit the random access message on the M repeated transmission resources and the correspondence (may also be referred to as a mapping relationship) between the determined beam and the M repeated transmission resources include, but are not limited to, those described in embodiments a to E.
Embodiment a, N1 is less than M:
the signal transmission method may further include: the terminal equipment randomly selects N2 reference signals except N1 reference signals from a plurality of reference signals, wherein the sum of N1 and N2 is equal to M; alternatively, M reference signals are randomly selected from among the plurality of reference signals. The wave beam adopted by each repeated transmission resource for sending the random access message is the wave beam corresponding to each repeated transmission resource in M wave beams; the M beams are beams associated with N1 reference signals and N2 reference signals, or beams associated with M reference signals.
For example, M is 3, M repeated transmission resources include repeated transmission resource 1, repeated transmission resource 2, and repeated transmission resource 3, and M beams include beam 1, beam 2, and beam 3. Wherein, the corresponding beam of the repeated transmission resource 1 in the M beams is the beam 1, the corresponding beam of the repeated transmission resource 2 in the M beams is the beam 2, and the corresponding beam of the repeated transmission resource 3 in the M beams is the beam 3. Then, the terminal device transmits the random access signal on the repeated transmission resource 1 by adopting the beam 1, transmits the random access signal on the repeated transmission resource 2 by adopting the beam 2, and transmits the random access signal on the repeated transmission resource 3 by adopting the beam 3.
Wherein, the M repeated transmission resources arranged according to the index size sequence are in one-to-one correspondence with the M wave beams arranged according to the index size sequence.
Alternatively, the M repeated transmission resources arranged in the order of the indexes from small to large correspond to the M beams arranged in the order of the indexes from large to small one by one. For example, in connection with fig. 3a, m is 3, and m repeated transmission resources are arranged in order of index from large to small: the method comprises the steps of repeatedly transmitting resource 1, repeatedly transmitting resource 2 and repeatedly transmitting resource 3, wherein M wave beams are arranged in the sequence from big to small according to indexes: beam 1, beam 2, and beam 3. Then, the repetition transmission resource 1 corresponds to the beam 1, the repetition transmission resource 2 corresponds to the beam 2, and the repetition transmission resource 3 corresponds to the beam 3.
Alternatively, the M repeated transmission resources arranged in the order of the indexes from large to small correspond one to the M beams arranged in the order of the indexes from large to small. For example, in connection with fig. 3b, m is 3, and m repeated transmission resources are arranged in order of index from large to small: the repeated transmission resource 3, the repeated transmission resource 2 and the repeated transmission resource 1, and the M wave beams are arranged in the order from the big index to the small index: beam 1, beam 2, and beam 3. Then, the repetition transmission resource 3 corresponds to the beam 1, the repetition transmission resource 2 corresponds to the beam 2, and the repetition transmission resource 1 corresponds to the beam 3.
Alternatively, the M beams may be arranged in order of index from large to small, and the M beams may be arranged in order of index from large to small of their associated reference signals.
Alternatively, the M repeated transmission resources may be arranged in order of the indexes from small to large, in order of the M repeated transmission resources from front to back in the time domain, or in order of the M repeated transmission resources from back to front in the time domain.
In embodiment B, N1 is less than M:
the signal transmission method may further include: the terminal equipment selects N3 reference signals from N1 reference signals, wherein N3 is a value smaller than or equal to N1 in the first set; the first set includes a plurality of values that are allowed to be selected for the number of retransmissions, and each of the plurality of values is an integer greater than or equal to 1. The wave beam adopted by each repeated transmission resource for sending the random access message is the corresponding wave beam in N3 wave beams associated with N3 reference signals; the N3 beams are in one-to-one correspondence with the M repeated transmission resources arranged in the order of the size of the index in a cyclic manner in the order of the size of the index. Alternatively, N3 may also be the largest one of the values in the first set that is less than or equal to N1.
For example, in connection with fig. 4a, m is equal to 8, N1 is equal to 3, and the first set includes a plurality of values: 2. 4, 6 and 8. It can be seen that N1 is smaller than M, then N3 may be equal to 2, and the terminal device may select 2 reference signals from the N1 reference signals having reference signal received powers (reference signal receiving power, RSRP) greater than the preset value. The beams associated with the 2 reference signals are arranged according to the order of the sizes of the indexes: beam 1 and beam 2, and 8 repeated transmission resources are arranged in the order of the index: repeating transmission resource 1, repeating transmission resource 2, repeating transmission resource 3, repeating transmission resource 4, repeating transmission resource 5, repeating transmission resource 6, repeating transmission resource 7, repeating transmission resource 8. Beam 1 and beam 2 are in one-to-one correspondence with the 8 repeated transmission resources arranged in a cyclic manner according to the arrangement, namely beam 1 corresponds to repeated transmission resource 1, and beam 2 corresponds to repeated transmission resource 2; cyclically, beam 1 again corresponds to repetition transmission resource 3, beam 2 again corresponds to repetition transmission resource 4, beam 1 also corresponds to repetition transmission resource 5, beam 6 also corresponds to repetition transmission resource 6, beam 1 also corresponds to repetition transmission resource 7, and beam 2 also corresponds to repetition transmission resource 8.
Optionally, the N3 beams correspond to the M repeated transmission resources arranged according to the order of the indexes in a cyclic manner, which may be: the N3 wave beams are in one-to-one correspondence with the M repeated transmission resources which are arranged in the order from the big index to the small index in a cyclic manner in the order from the big index to the small index; alternatively, the N3 beams may be in one-to-one correspondence with M repeated transmission resources arranged in the order of the indexes from the small to the large in a cyclic manner in the order of the indexes from the large to the small.
Alternatively, the first set may be configured by the network device to the terminal device, or may be predefined. The plurality of values in the first set may correspond to the same preset value, or each of the plurality of values may correspond to a respective preset value.
In embodiment C, N1 is less than M:
the beam used for transmitting the random access message on each repeated transmission resource is a corresponding beam in N1 beams associated with N1 reference signals.
The N1 beams are in one-to-one correspondence with M repeated transmission resources arranged in the order of the size of the index in a cyclic manner in the order of the size of the index. That is, the N1 beams arranged in the order of the size of the index may correspond one-to-one with the M repeated transmission resources arranged in the order of the size of the index in a policy of sequential mapping (sequential mapping).
For example, in connection with fig. 4b, m is equal to 8, N1 is equal to 3, and beams associated with N1 reference signals having RSRP greater than a preset value among the plurality of reference signals are arranged according to the order of the sizes of the indexes: the beam 1, beam 2, beam 3,8 repeated transmission resources are arranged according to the order of the size of the index: repeating transmission resource 1, repeating transmission resource 2, repeating transmission resource 3, repeating transmission resource 4, repeating transmission resource 5, repeating transmission resource 6, repeating transmission resource 7, repeating transmission resource 8. Beam 1, beam 2 and beam 3 are in one-to-one correspondence with the 8 repeated transmission resources arranged in a cyclic manner according to the arrangement, namely beam 1 corresponds to repeated transmission resource 1, beam 2 corresponds to repeated transmission resource 2, and beam 3 corresponds to repeated transmission resource 3; cyclically, beam 1 again corresponds to repetition transmission resource 4, beam 2 again corresponds to repetition transmission resource 5, beam 3 again corresponds to repetition transmission resource 6, beam 1 also corresponds to repetition transmission resource 7, and beam 2 also corresponds to repetition transmission resource 8.
In embodiment D, N1 is less than M, and the ratio of M to N1 is an integer:
the beam used for transmitting the random access message on each repeated transmission resource is a corresponding beam in N1 beams associated with N1 reference signals.
The N1 beams arranged according to the order of the index are in one-to-one correspondence with the M repeated transmission resources arranged according to the order of the index in such a manner that each beam is repeated X times in succession, X being equal to the ratio of M to N1. That is, the N1 beams arranged in the order of the size of the index may correspond one-to-one to the M repeated transmission resources arranged in the order of the size of the index according to a cyclic mapping (cyclic mapping) policy.
For example, in connection with fig. 5a, m is equal to 8, N1 is equal to 2, and N1 beams associated with N1 reference signals having RSRP greater than a preset value in the plurality of reference signals are arranged according to the order of the sizes of the indexes: beam 1, beam 2,8 repeated transmission resources are arranged in order of size of the index: repeating transmission resource 1, repeating transmission resource 2, repeating transmission resource 3, repeating transmission resource 4, repeating transmission resource 5, repeating transmission resource 6, repeating transmission resource 7, repeating transmission resource 8. The arranged beams 1 and 2 are in one-to-one correspondence with the arranged M repeated transmission resources in a manner that each beam is continuously repeated 4 (i.e., X) times, that is, the beam 1 corresponds to the arranged continuous repeated transmission resource 1, the repeated transmission resource 2, the repeated transmission resource 3 and the repeated transmission resource 4, and the beam 2 corresponds to the arranged continuous repeated transmission resource 5, the repeated transmission resource 6, the repeated transmission resource 7 and the repeated transmission resource 8.
Optionally, the N1 beams arranged according to the size order of the index are in a one-to-one correspondence with the M repeated transmission resources arranged according to the size order of the index in a manner that each beam is repeated for X times continuously, which may be: n1 wave beams which are arranged according to the sequence from the big index to the small index are in one-to-one correspondence with M repeated transmission resources which are arranged according to the sequence from the big index to the small index in a mode that each wave beam is continuously repeated for X times; alternatively, N1 beams arranged in the order of the index from large to small may be sequentially repeated X times each with M repeated transmission resources arranged in the order of the index from small to large.
Embodiment E, N1 is less than M, and the ratio of M to N1 is not an integer:
the beam used for transmitting the random access message on each repeated transmission resource is a corresponding beam in N1 beams associated with N1 reference signals.
N1 wave beams arranged according to the index size sequence are in one-to-one correspondence with M1 repeated transmission resources arranged according to the index size sequence in a mode that each wave beam is continuously repeated for X times, and X is equal to a value obtained by rounding down the ratio of M to N1; m1 is equal to the product of X and N1, and M1 repeated transmission resources are M1 repeated transmission resources with the smallest or largest index in the M repeated transmission resources.
The N4 beams arranged in the order of the index size are in one-to-one correspondence with the M2 repeated transmission resources arranged in the order of the index size in such a manner that each beam is repeated X times in succession. N4 is equal to the value rounded up by the ratio of M2 to X; the N4 beams are the lowest or largest indexed beam of the N1 beams; m2 is equal to the difference between M and M1; the M2 retransmission resources are retransmission resources other than the M1 retransmission resources among the M retransmission resources.

For example, in connection with fig. 5b, m is equal to 8, N1 is equal to 3, and N1 beams associated with N1 reference signals having RSRP greater than a preset value in the plurality of reference signals are arranged according to the order of the sizes of the indexes: the beam 1, beam 2, beam 3,8 repeated transmission resources are arranged according to the order of the size of the index: repeating transmission resource 1, repeating transmission resource 2, repeating transmission resource 3, repeating transmission resource 4, repeating transmission resource 5, repeating transmission resource 6, repeating transmission resource 7, repeating transmission resource 8. The arranged beams 1, 2 and 3 are in one-to-one correspondence with the first 6 (i.e. M1) repeated transmission resources arranged in a manner that each beam is continuously repeated 2 (i.e. X) times, that is, the beam 1 corresponds to the repeated transmission resource 1 and the repeated transmission resource 2 arranged continuously, the beam 2 corresponds to the repeated transmission resource 3 and the repeated transmission resource 4 arranged continuously, and the beam 3 corresponds to the repeated transmission resource 5 and the repeated transmission resource 6 arranged continuously. The first 1 (i.e., N4) beams correspond to 2 (i.e., M2) retransmission resources among the 8 retransmission resources except the above 6 retransmission resources, i.e., beam 1 also corresponds to the consecutive repetition transmission resource 7, repetition transmission resource 8.

Optionally, the N1 beams arranged in the order from the large index to the small index are sequentially repeated for X times, so that each beam corresponds to M1 repeated transmission resources arranged in the order from the small index to the large index one by one; the N4 beams arranged in the order of the index from large to small are sequentially repeated X times each with M2 repeated transmission resources arranged in the order of the index from small to large in one-to-one correspondence.
The above embodiments a to E are applicable to the case where the terminal device repeatedly transmits the random access message M times using different beams, and the terminal device determines the beam used for transmitting the random access message each time. The embodiments B to E may also be applied to, when the number of beams used for M times of sending the random access message is smaller than M, determining, by the terminal device, a correspondence between the beam used for M times of sending the random access message and M repeated transmission resources when there is one beam corresponding to a plurality of repeated transmission resources among the M repeated transmission resources.
In summary, in the signal transmission method, the terminal device determines N1 reference signals with RSRP greater than a preset value from a plurality of reference signals, where N1 is an integer greater than or equal to 0; the terminal device sends random access messages on M repeated transmission resources respectively, and the wave beam adopted by each repeated transmission resource for sending the random access messages is determined based on N1 wave beams associated with N1 reference signals. It can be seen that the terminal device may determine a beam to be used for transmitting the random access message on each repeated transmission resource based on beams associated with N1 reference signals having RSRP greater than a preset value among the plurality of reference signals. The signal transmission method can realize that the terminal equipment repeatedly sends the random access message for a plurality of times, thereby enhancing uplink coverage in the random access process and improving the success rate of the random access of the terminal equipment.
