Description

Transmission parameter configuration method, device and computer readable storage medium
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a transmission parameter configuration method, an apparatus, and a computer-readable storage medium.
Background
The 5G NR standard introduces an uplink transmission mechanism of pre-Configured scheduling (transmission with Configured Grant). In configuring the scheduled uplink transmission, when the terminal wants to send data, the terminal can directly transmit on the preconfigured resource without sending a scheduling request to the base station and waiting for the authorization information of the base station. On the other hand, in order to improve the spectrum efficiency and the number of Access users, a new Non-Orthogonal Multiple Access (NOMA) technology has attracted much attention. When NoMA is combined with a pre-configured scheduling mechanism, two or more users may transmit on the same time-frequency resource. When the MA code words or DMRS of the users collide, the receiver can not demodulate correctly. Therefore, in order to avoid the occurrence of continuous MA codewords or DMRS collisions between users, an effective processing method is urgently needed to be proposed, so as to improve demodulation performance.

Specifically, the MA codeword or DMRS configuration may be configured according to a slot (slot), i.e., different slots may configure different MA codewords or DMRSs. In addition, in the pre-configured transmission, the user may transmit data in a repetitive (retransmission) manner, i.e., the user may repeatedly transmit the same data in several consecutive time slots. Since each transmission uses a different time slot in the repetition mode, the MA codeword or DMRS configuration may also be configured according to the second transmission in the repetition transmission, that is, each transmission in the repetition transmission uses a different MA codeword or DMRS. As shown in fig. 5, the number of times of the repeated transmission of the user is 4, the nth, nth +1, nth +2, and nth +3 slots are occupied respectively, and an MA codeword or a DMRS may be configured according to the slot information or the transmission of the number of times.
Specifically, the configuration information at least includes information of one first MA codeword or first DMRS port, where the first MA codeword or the first DMRS port may be a MA codeword or a DMRS of a reference slot, or may be a MA codeword or a DMRS transmitted for the first time in a repeated transmission.

wherein f1(k) represents a value determined according to the number of transmissions k; UE _ ID represents a terminal identity, and f2(UE _ ID) represents a value determined according to the UE _ ID; offset represents an offset value; a is a predefined or configured integer.
24. A method for configuring transmission parameters, the method comprising:
setting configuration information; the configuration information is multiple access MA code words related to a time domain or demodulation reference signal DMRS information;
and sending the configuration information for the terminal to determine the MA code word or DMRS information corresponding to the time domain resource according to the configuration information.
25. A transmission parameter configuration apparatus, comprising:
the receiving module is used for receiving the configuration information; the configuration information is multiple access MA code words related to a time domain or demodulation reference signal DMRS information;
and the determining module is used for determining the MA code word or the DMRS information corresponding to the time domain resource based on the configuration information.
26. A transmission parameter configuration apparatus, comprising:
the setting module is used for setting configuration information; the configuration information is multiple access MA code words related to a time domain or demodulation reference signal DMRS information;
and the sending module is used for sending the configuration information and determining the MA code word or the DMRS information corresponding to the time domain resource by the terminal according to the configuration information.
27. A transmission parameter configuration apparatus, comprising: a processor and a memory for storing a computer program capable of running on the processor,
wherein the processor is adapted to perform the steps of the method of any one of claims 1-23 or to perform the steps of the method of claim 24 when running the computer program.
28. A computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the steps of the method of any one of claims 1 to 23 or carries out the steps of the method of claim 24.
