[0180] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0181] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0182] In the embodiments of the present disclosure, the terms "network" and "system" are often used interchangeably, but those skilled in the art will understand their meanings.

[0183] First, let’s introduce the following contents:

[0184] In the NR system, the sequence generation of SRS resources is related to cyclic shift.

[0185] The SRS sequence is generated as follows:

[0186] in, is the length of the SRS sequence, is a sequence generated based on δ, cyclic shift α and base sequence, is the number of OFDM symbols included in one SRS resource, δ=log2(K TC ), transmission comb number K TC ∈{2,4,8} is determined based on high-level parameter configuration, p i is the number of the antenna port of the SRS resource, α i is the antenna port p i The corresponding cyclic shift.

[0187] For SRS resources that include multiple antenna ports, there are currently two time domain resource mapping methods:

[0188] Mode 1: All SRS ports of the SRS resource are mapped to all OFDM symbols configured by the base station for the SRS resource;

[0189] Method 2: All SRS ports of the SRS resource are divided into two groups. These two groups of SRS ports are mapped to all OFDM symbols using TDM (time division multiplexing). That is, the two groups of SRS ports each occupy half of the OFDM symbols configured by the base station for the SRS resource, and the OFDM symbols occupied by the two groups of SRS ports do not overlap.

[0205] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

The reference signal transmission method includes the following steps:

[0208] Step 100, determining cyclic shifts used by multiple antenna ports of SRS resources respectively;

[0209] Optionally, the antenna port in each embodiment of the present disclosure mainly refers to the antenna port of the SRS, and can also be called an SRS port, an SRS antenna port, a port, etc.

[0210] Optionally, the terminal may determine the cyclic shifts used by the multiple antenna ports of the SRS resource respectively based on the relevant information of the cyclic shift configured by the network side device or predefined by the protocol;

[0211] Step 110: Send the SRS based on the cyclic shifts used by the multiple antenna ports respectively;

[0212] At least one first antenna port among the multiple antenna ports is mapped to a first time domain resource, at least one second antenna port among the multiple antenna ports is mapped to a second time domain resource, the first antenna port is different from the second antenna port, and the first time domain resource is different from the second time domain resource;

[0213] Specifically, when the terminal performs the cyclic shift used by the multiple antenna ports respectively and sends the SRS, for each antenna port, the terminal can determine the SRS sequence corresponding to each antenna port based on the cyclic shift corresponding to each antenna port, and based on the sequence, transmit the SRS resource to each antenna port (that is, transmit the sequence corresponding to each antenna port to the network device).

[0214] Specifically, when the terminal sends the SRS based on the cyclic shift used by the multiple antenna ports, for each antenna port, the terminal can determine the SRS sequence corresponding to each antenna port based on the cyclic shift corresponding to each antenna port, and transmit the SRS resource to each antenna port based on the sequence (i.e., transmit the sequence corresponding to each antenna port to the network device).

[0215] Specifically, the multiple antenna ports of the SRS resource include at least one first antenna port and at least one second antenna port; the first antenna port and the second antenna port are mapped to different time domain resources, so that the first antenna port and the second antenna port do not interfere with each other when using the same cyclic shift, so that one SRS resource can include more antenna ports, and the multiple antenna ports do not cause significant interference to each other.

[0216] Optionally, in an embodiment of the present disclosure, antenna ports mapped to the same time domain resources can be considered as one antenna port group, and antenna ports mapped to different time domain resources can be considered as belonging to different antenna port groups; that is, the first antenna port and the second antenna port belong to different antenna port groups.

[0217] When the number of antenna ports configured with SRS resources is M, it is assumed that the number of these M antenna ports is: p i =1000+i, i=0,...,M-1, use {x1,...,x m} means numbered x1,...,x m The antenna ports of a group are an antenna port group.

[0218] Optionally, each antenna port group includes the same number of antenna ports.

[0219] Optionally, the numbering of antenna ports in each antenna port group satisfies any one of the following conditions:

[0220] (a) The numbers (ie, indexes or IDs) of the antenna ports in an antenna port group are adjacent; that is, the numbers of the antenna ports in any antenna port group are adjacent.

[0221] (b) The antenna ports in the antenna port group are numbered at an interval of K (K is an integer greater than 1).

[0222] Optionally, K can be a multiple of 2 or 4;

[0223] For example, odd-numbered antenna ports are grouped together, and even-numbered antenna ports are grouped together.

[0224] Optionally, each antenna port group in the Z antenna port groups includes the same number of antenna ports.

[0225] Optionally, the number of antenna ports included in each antenna port group in the Z antenna port groups is different.

[0226] For example, the antenna port number is as well as The antenna ports of the SRS resource are mapped to the same OFDM symbol, where M is the number of antenna ports included in the SRS resource, C is a constant (e.g., C=1000), m is a constant (e.g., m=4, or 8, etc.) or a function of n (e.g., m=2n, or m=4n, etc.), and n is a constant or a number determined based on a parameter indicated by the base station (e.g., n=2, or 4).

Exemplarily, the Z antenna port groups may share the same cyclic shift set, where the number of cyclic shifts included in the cyclic shift set is equal to the number of antenna ports included in one antenna port group.

[0531] (b) The antenna ports in the antenna port group are numbered at an interval of K (K is an integer greater than 1).

[0532] Optionally, K can be a multiple of 2 or 4;
