Because the target device can generate the pseudo-random sequence according to the resource corresponding to the transmission target data, that is, one resource corresponds to one pseudo-random sequence, and one pseudo-random sequence is used for generating the first sequence corresponding to one target data, in a scenario of multi-transceiver node or multi-antenna panel transmission, the target device can generate a plurality of pseudo-random sequences according to a plurality of determined resources (one resource is a resource corresponding to transmission of one target data) to generate the first sequence corresponding to each target data (one target data corresponds to one first sequence), so that a problem of interference among a plurality of target data in a scenario of multi-transceiver node or multi-antenna panel transmission can be avoided, and thus, the transmission performance of the target data can be improved.

Accordingly, the UE receives the indication information from the network side device.
Step 201b, the UE determines the resource according to the indication information.
In the embodiment of the present invention, because the UE may determine the resource corresponding to the target data transmitted by the target device according to the indication information received from the network side device, and then generate the pseudo-random sequence corresponding to the resource according to the resource, that is, one indication information corresponds to one resource, one resource corresponds to one pseudo-random sequence, and one pseudo-random sequence is used to generate the first sequence corresponding to one target data, in a scenario of multi-transmitting node or multi-antenna panel transmission, the UE may determine a plurality of resources according to the received plurality of indication information, and generate a plurality of pseudo-random sequences according to the plurality of resources to generate the first sequence corresponding to each target data (one target data corresponds to one first sequence), so that a problem of interference between a plurality of target data in a scenario of multi-transmitting node or multi-antenna panel transmission can be avoided, thereby, the transmission performance of the target data can be improved.

And step 202b, the target device generates a pseudo-random sequence according to the first numerical value.
It can be understood that, in the embodiment of the present invention, the target device may determine the target algorithm from the first algorithm to the eleventh algorithm according to the target data, and determine the first value (i.e., c) in the target algorithm according to the resource corresponding to the target data transmitted by the target device init ) And then according to c obtained init A pseudo-random sequence (i.e., the second pseudo-random sequence described in the above embodiment) is generated, and then a method of generating a pseudo-random sequence in the related art is used to generate a target pseudo-random sequence (i.e., c (×) described in the above embodiment).
In the embodiment of the invention, the target device can generate a first numerical value according to the resource corresponding to the target data transmitted by the target device and generate a pseudo-random sequence according to the first numerical value, i.e. a resource corresponds to a first value, a first value corresponds to a pseudo-random sequence, a pseudo-random sequence is used to generate a first sequence corresponding to a target data, therefore, in the scenario of multi-transmitting-receiving node or multi-antenna panel transmission, the target device may generate a plurality of first values according to the received plurality of resources, and generate a plurality of pseudo-random sequences according to the plurality of first values, the first sequence corresponding to each target data is generated (one target data corresponds to one first sequence), so that the problem that interference exists among a plurality of target data under a multi-receiving-and-transmitting node or multi-antenna panel transmission scene can be avoided, and the transmission performance of the target data can be improved.

In the embodiment of the present invention, the value set includes a plurality of values, and the plurality of values include a value of g.
Optionally, in this embodiment of the present invention, the predefined value set may be {0,1} or {0,1,2 }.
Step 202a 1', the target device determines a target algorithm according to the value set.
Exemplarily, when the indication information includes an identifier of a TB of the uplink traffic channel, if the value set is {0,1}, the target algorithm is the first algorithm or the third algorithm, and different values of g correspond to different TBs, for example, a value of g of 0 indicates TB0, and a value of g of 1 indicates TB 1; when the indication information includes an identifier of a control resource set of the downlink control channel, if a value range is {0,1,2}, the target algorithm is a sixth algorithm, and different values of g correspond to different control resource sets; when the indication information includes the identifier of the port set of the reference signal, if the value set is {0,1}, the target algorithm is a seventh algorithm, and if the value set is {0,1,2}, the target algorithm is an eighth algorithm, different values of g correspond to different port sets of the reference signal (for example, different values of g correspond to different port groups of DMRS, and different values of g correspond to different code division multiplexing groups of DMRS).
And step 202a 1' in which the target equipment adopts a target algorithm to generate a first numerical value according to the value of g.
It can be understood that, for a scenario of multi-transceiver node or multi-antenna panel transmission, after determining a target algorithm, the target device substitutes a value of each g of a plurality of g determined according to a plurality of resources into the target algorithm to obtain a plurality of first values, where one first value corresponds to one pseudorandom sequence.
Exemplarily, it is assumed that the target device is a network side device, the target data is a DMRS of a PDSCH, and a value set is {0,1 }. As shown in fig. 7, the network side device transmits DMRS1 of PDSCH and DMRS2 of PDSCH to the UE through two TRPs (e.g., TRP1 and TRP2), respectively; when the network side equipment transmits the DMRS1 of the PDSCH to the UE through the TRP1, the resource corresponding to the DMRS1 for transmitting the PDSCH, which is determined by the network side equipment, comprises a port group 1 of the DMRS1 for transmitting the PDSCH (namely, the identifier of the port group for transmitting the DMRS1 of the PDSCH is 1), and a code division multiplexing group 1 of the DMRS1 for the PDSCH (namely, the identifier of the code division multiplexing group for transmitting the DMRS1 of the PDSCH is 1), and the network side equipment determines the value of g to be 0 according to the identifier 1 of the port group 1 and the identifier 1 of the code division multiplexing group 1; when the network side equipment transmits the DMRS2 of the PDSCH to the UE through the TRP2, the resource corresponding to the DMRS2 for transmitting the PDSCH determined by the network side equipment comprises a port group 2 of the DMRS2 for transmitting the PDSCH (namely, the identifier of the port group for transmitting the DMRS2 of the PDSCH is 2), and a code division multiplexing group 2 of the DMRS2 for the PDSCH (namely, the identifier of the code division multiplexing group for transmitting the DMRS2 of the PDSCH is 2), and the network side equipment determines that the value of g is 1 according to the identifier 2 of the port group 2 and the identifier 2 of the code division multiplexing group 2. The network side device may determine the seventh algorithm as the target algorithm according to the value set {0,1}, that is, the target algorithm is
Figure BDA0001783361200000081
Then, the network side device substitutes the values 0 and 1 of g into the target algorithm respectively to obtain two different first values, that is, two different pseudo-random sequences can be obtained, so that different DMRS sequences (for example, DMRS sequence 1 and DMRS sequence 2) can be obtained.
Further exemplarily, it is assumed that the target device is a network side device, the target data is a PDCCH, and the value set is {0,1,2 }. As shown in fig. 8, the network side device passes three TRPs (e.g., TRP1,TRP2 and TRP3) transmitting PDCCH1, PDCCH2 and PDCCH3, respectively, to the UE; when the network side device sends a PDCCH1 to the UE through the TRP1, the resource corresponding to the PDCCH1 sent by the network side device includes a control resource set 1 for sending the PDCCH1 (that is, an identifier of the control resource set for sending the PDCCH1 is 1), and the network side device determines that a value of g is 0 according to the identifier 1 of the control resource set 1; when the network side device sends a PDCCH2 to the UE through the TRP2, the resource corresponding to the PDCCH2 sent by the network side device includes a control resource set 2 for sending the PDCCH2 (that is, the identifier of the control resource set for sending the PDCCH2 is 2), and the network side device determines that the value of g is 1 according to the identifier 2 of the control resource set 2; when the network side device sends the PDCCH3 to the UE through the TRP3, the resource corresponding to the PDCCH3 sent by the network side device includes the control resource set 3 sending the PDCCH3 (that is, the identifier of the control resource set sending the PDCCH3 is 3), and the network side device determines that the value of g is 2 according to the identifier 3 of the control resource set 3. The network side device may determine the sixth algorithm as the target algorithm according to the value set {0,1,2}, that is, the target algorithm is c init =(n RNTI ·2 16 +g·2 14 +n ID )mod2 31 (ii) a Then, the network side device substitutes values 0, 1, and 2 of g into the target algorithm, respectively, to obtain three different first values, that is, three different pseudo-random sequences can be obtained, so that scrambling sequences (for example, scrambling sequence 1 corresponding to PDCCH1, scrambling sequence 2 corresponding to PDCCH2, and scrambling sequence 3 corresponding to PDCCH3) corresponding to each PDCCH (i.e., PDCCH1, PDCCH2, and PDCCH3) can be obtained.
It should be noted that, in the embodiment of the present invention, multiple target data transmitted by a network side device through multiple transmitting and receiving nodes are the same type of data. Illustratively, the types of the target data transmitted by the network-side device through the multiple transmitting-receiving nodes are all traffic channel types, or all control channel types, or all reference signal types.

Step 402, the target device scrambles the control channel by using the pseudo-random sequence to generate a scrambling sequence corresponding to the control channel.
And 403, the target device generates a reference signal sequence corresponding to the reference signal according to the pseudo-random sequence.
The pseudo-random sequence in step 401, step 402, and step 403 is a pseudo-random sequence generated by using the pseudo-random sequence generation method provided in the embodiment of the present invention, that is, the second pseudo-random sequence in the embodiment.
It is to be understood that, in the embodiment of the present invention, the target device may obtain a target pseudorandom sequence (i.e., c (×) described in the above embodiment) according to the first pseudorandom sequence and the second pseudorandom sequence described in the above embodiment, and then scramble the traffic channel by using the target pseudorandom sequence to generate a first sequence corresponding to the traffic channel, that is, generate a scrambled sequence after scrambling the traffic channel. Alternatively, the target device may obtain a target pseudorandom sequence (i.e., c (×) described in the foregoing embodiment) according to the first pseudorandom sequence and the second pseudorandom sequence described in the foregoing embodiment, and then scramble the control channel by using the target pseudorandom sequence to generate a first sequence corresponding to the control channel, that is, generate a scrambled sequence after scrambling the control channel.

In the embodiment of the present invention, since the target device may scramble the traffic channel or the control channel using the pseudo-random sequence after generating the pseudo-random sequence (one pseudo-random sequence is used to generate the first sequence corresponding to one target data), or generate the reference signal sequence corresponding to the reference signal according to the pseudo-random sequence, in a scenario of multi-transmitting node or multi-antenna panel transmission, the target device may scramble the traffic channel or the control channel corresponding to the pseudo-random sequence using each of the generated plurality of pseudo-random sequences (scramble one traffic channel or one control channel using one pseudo-random sequence), or generate the reference signal sequence corresponding to the reference signal corresponding to the pseudo-random sequence according to each of the generated plurality of pseudo-random sequences (one pseudo-random sequence generates one reference signal sequence corresponding to one reference signal), therefore, the problem of interference among a plurality of target data under the transmission scene of a plurality of receiving and transmitting nodes or a plurality of antenna panels can be avoided, and the transmission performance of the target data can be improved.
