The base station may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the name of a device having a base station function may be different, for example, in a Long Term Evolution (LTE) system, it is called eNodeB or eNB, and in a 5G NR (New Radio) system, it is called gNodeB or gNB. With the development of communication technology, the description of "base station" may change.

[0022] Generally, the number of connections supported by conventional communication systems is limited and easily realized, but with the development of communication technology, mobile communication systems support not only conventional communication but also, for example, device to device (D2D) communication, machine to machine (M2M) communication, machine type communication (MTC), vehicle to vehicle (V2V) communication, and vehicle to everything (V2X) systems, etc. The embodiments of the present application can also be applied to these communication systems.

[0023] 2 shows a flow chart of a method for transmitting an SRS provided by one exemplary embodiment of the present disclosure, which is applied to a terminal of the communication system shown in FIG. 1, and includes the following steps: Step 210, receiving configuration information of an SRS resource, where the SRS resource includes eight antenna ports.

[0024] Exemplarily, the terminal receives configuration information of an SRS resource sent by a network device, and the configuration information is used to configure one SRS resource for the terminal.

[0025] The configured SRS resource includes 8 antenna ports. That is, the configuration information of the SRS resource is as follows:

number

[0026] Alternatively, the configured SRS resource includes at least two antenna port groups (i.e., K antenna port groups) corresponding to eight antenna ports. That is, the configuration information of the SRS resource includes the number of antenna ports of the SRS.

number

number

[0027] Step 220: map SRSs corresponding to the at least two antenna port groups to physical resources corresponding to different transmission combs, and simultaneously transmit SRSs corresponding to the at least two antenna port groups, where the at least two antenna port groups are obtained by dividing based on eight antenna ports.

[0028] When the UE measures the uplink channel quality, it maps one SRS resource to the same physical resource (PR). Exemplarily, the physical resource refers to continuous carrier resources in the frequency domain, and one physical resource block (PRB) corresponds to 12 continuous carriers in the frequency domain and one slot in the time domain.

[0029] Exemplarily, the uplink channel includes at least one of a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH). The terminal can map one SRS resource to the physical resources of the PUCCH and / or the PUSCH.

[0030] Exemplarily, the terminal maps one SRS resource to the same physical resource according to configuration information, the configuration information including at least one parameter among the following parameters: Transmission comb parameter k TC ; Frequency domain offset parameter

[0031] The transmit comb parameters are used to indicate the comb structure in the frequency domain of the SRS resources, i.e., the SRS resources are not mapped onto consecutive subcarriers. The transmit comb parameters are denoted using comb, where comb=k TC , k TC The value of is a positive integer, and there is a (k TC −1) subcarriers apart, i.e., there is a (k −1) subcarrier interval between adjacent resource elements (RE) in the SRS resource. TC-1) subcarriers apart, for example, when comb=8, 7 subcarriers are spaced between adjacent RE resources in one SRS resource. The frequency domain offset value parameter refers to the offset value of the subcarrier occupied by the first RE resource in one SRS resource, and the frequency domain offset value parameter is a non-negative integer smaller than the transmission comb parameter. The SRS configuration bandwidth refers to the frequency bandwidth occupied by the SRS resource. The cyclic shift parameter refers to the number of bits of sequence cyclic shift. The antenna port is a logical transmission channel defined by a reference signal, and the antenna port is mapped to a physical antenna to transmit a signal. The time domain position of the transmission comb is used to indicate that the transmission comb refers to the symbol occupied in the slot.

[0032] Exemplarily, the above-mentioned configuration information may further include a length of the ZC sequence, and the length of the ZC sequence refers to the length of the ZC sequence. For example, the terminal generates eight SRS sequences based on at least one ZC sequence, and carries SRS of eight antenna ports through the eight SRS sequences.

[0033] Exemplarily, each antenna port group corresponds to one transmission comb, and the terminal maps the SRSs corresponding to at least two antenna port groups to physical resources corresponding to at least two transmission combs, and transmits the SRSs corresponding to the at least two antenna port groups simultaneously.

[0034] Exemplarily, the at least two antenna port groups can be mapped to antenna port groups on the same antenna panel or different antenna panels, i.e., the at least two antenna ports map to antenna port groups on M antenna panels, where M is a positive integer equal to or greater than 8. For example, a first antenna port group of the at least two antenna port groups maps to a first antenna panel, and a second antenna port group of the at least two antenna port groups maps to a second antenna panel.

[0035] Exemplarily, a terminal occupies N consecutive Orthogonal Frequency-Division Multiplexing (OFDM) symbols in one SRS resource, where N={1, 2, 4}.

[0036] For example, the functions of the above SRS resource are: A codebook, Antenna switching, and at least one of:

[0037] The terminal may perform codebook-based channel quality sensing, or may perform channel quality sensing when performing antenna switching, or may perform non-codebook-based channel quality sensing.

[0038] For example, the transmission comb parameter k TC The range of values ​​for is {2,4,8,12}. For example, k TCTaking =2 as an example, when the transmission comb parameter is equal to 2, the terminal maps two transmission combs to one PRB: a first transmission comb 301 and a second transmission comb 302, the frequency domain offset value parameter of the first transmission comb 301 is 0, the frequency domain offset value parameter of the second transmission comb 302 is 1, the adjacent subcarriers in each transmission comb are spaced apart by one subcarrier, and the subcarriers occupied by the first transmission comb 301 are subcarrier 0, subcarrier 2, subcarrier 4, subcarrier 6, subcarrier 7, subcarrier 8, subcarrier 9, subcarrier 10, subcarrier 11, subcarrier 12, subcarrier 13, subcarrier 14, subcarrier 15, subcarrier 16, subcarrier 17, subcarrier 18, subcarrier 19, subcarrier 20, subcarrier 21, subcarrier 22, subcarrier 23, subcarrier 24, subcarrier 25, subcarrier 26, subcarrier 27, subcarrier 28, subcarrier 29, subcarrier 30, subcarrier 31, subcarrier 32, subcarrier 33, subcarrier 34, subcarrier 35, subcarrier 36, subcarrier 37, subcarrier 38, subcarrier 39, subcarrier 40, subcarrier 41, subcarrier 42, subcarrier 43, subcarrier 44, subcarrier 45, subcarrier 46, subcarrier 47, subcarrier 48, subcarrier 49, subcarrier 41, subcarrier 42, subcar 3 include subcarriers 1, 3, 5, 7, 9, and 11, and the subcarriers occupied by the second transmit comb 302 include subcarrier 1, subcarrier 3, subcarrier 5, subcarrier 7, subcarrier 9, and subcarrier 11, and the first transmit comb 301 and the second transmit comb 302 are both located at symbol 10 of one slot, and four antenna ports, port 0, port 1, port 2, and port 3, are mapped to the first transmit comb 301, and four antenna ports, port 4, port 5, port 6, and port 7, are mapped to the second transmit comb 302. Exemplarily, each transmit comb resource of the two transmit combs in FIG. 3 can occupy one OFDM symbol.

[0039] Exemplarily, the maximum value of the cyclic shift parameter of the transmission comb corresponding to the at least two antenna port groups is:

number

number

[0040] Alternatively, the maximum number of cyclic shift parameters supported by the transmission comb parameters is 8;

number

[0041] Exemplarily, the maximum number of cyclic shift parameters supported by the transmission comb parameters is 12;

number

[0042] Exemplarily, the above-mentioned configuration information includes one cyclic shift parameter corresponding to at least two antenna port groups, and after receiving the configuration information, the terminal calculates cyclic shift parameters corresponding to all antenna ports in the at least two antenna port groups based on the configured cyclic shift parameter.

[0043] Alternatively, the above-mentioned configuration information includes one cyclic shift parameter corresponding to each antenna port group among the at least two antenna port groups, and after receiving the configuration information, the terminal calculates, for each antenna port group, cyclic shift parameters corresponding to all ports in the antenna port group according to the cyclic shift parameter set for the antenna port group.

[0045] In some other embodiments, the transmission comb parameter k TC is equal to 8 or 12, only one SRS resource can be mapped to one PRB, and thus the minimum bandwidth parameter corresponding to the SRS configured bandwidth is equal to or greater than the bandwidth of 6 PRBs, or the SRS configured bandwidth is a multiple of the 6 PRB bandwidth, or the minimum bandwidth parameter corresponding to the SRS configured bandwidth is equal to or greater than the bandwidth of 8 PRBs, or the SRS configured bandwidth is a multiple of the 8 PRB bandwidth. In this way, only multiple RE resources can be mapped to multiple PRBs, and the measurement result of uplink channel quality is avoided from being unrepresentative due to the small RE resource.

[0046] In short, in the method for transmitting SRS provided by this embodiment, the eight antenna ports of the SRS resources can be divided into at least two antenna port groups, and after the terminal receives the configuration information of the SRS resource, the terminal maps the SRS corresponding to the at least two antenna port groups to physical resources corresponding to different transmission combs, and simultaneously transmits the SRS corresponding to the at least two antenna port groups, and the method is used to support the realization of related functions when the terminal uses eight transmitting antenna ports, for example, used to support codebook-based channel quality detection when the terminal uses eight transmitting antenna ports, or used to support non-codebook-based channel quality detection when the terminal uses eight transmitting antenna ports, or used to support channel quality detection during antenna switching when the terminal uses eight transmitting antenna ports.

[0047] In some embodiments, at least two antenna port groups may be mapped to at least two transmit combs with different frequency domain offset parameters of the transmit combs, and as shown in FIG. 4, step 220 may be implemented by step 420 as follows: Step 420: map the SRSs corresponding to the at least two antenna port groups to physical resources corresponding to the at least two transmission combs in a frequency domain dimension, and simultaneously transmit the SRSs corresponding to the at least two antenna port groups.

[0048] The above-mentioned antenna port groups have a one-to-one correspondence with the transmission combs. Optionally, the time domain positions of the transmission combs corresponding to at least two antenna port groups are the same. For example, the first transmission comb 301 and the second transmission comb 302 in FIG. 3 are both located at slot symbol 10.

[0049] Optionally, a transmit comb parameter k of a transmit comb corresponding to at least two antenna port groups. TCFor example, the transmission comb parameters of the first transmission comb 301 and the second transmission comb 302 in FIG.

[0051] Optionally, some or all of the frequency domain offset value parameters of the above-mentioned transmission comb are set for the terminal by the network device. Illustratively, the terminal receives a first frequency domain offset value parameter of a transmission comb corresponding to a first antenna port group, the first antenna port group being one of at least two antenna port groups, and calculates another frequency domain offset value parameter of a transmission comb corresponding to another antenna port group based on the first frequency domain offset value parameter, the other antenna port group being an antenna port group other than the first antenna port group of the at least two antenna port groups.

[0052] Alternatively, the terminal receives frequency domain offset value parameters of a transmit comb corresponding to at least two antenna port groups.

[0053] That is, the network device may obtain a frequency domain offset value parameter of one transmission comb for the terminal.

number

[0054] Alternatively, the terminal calculates the other frequency domain offset parameter according to the principle of adjacent transmission combs, or calculates the other frequency domain offset parameter according to the principle of uniform distribution, or calculates the other frequency domain offset parameter according to the principle of maximum spacing, or calculates the other frequency domain offset parameter according to other predefined principles. Exemplarily, the determination principles of the above four kinds of other frequency domain offset parameters are described below: 1) The principle of adjacent transmission combs.

[0059] 3) Principle of maximum spacing.

[0060] The difference in frequency domain offset parameter between connected transmission combs is maximum. For example, k TC For .times. ...

[0061] For example, as shown in FIG. 6, the k th transmission combs 601 and 602 in the SRS resource TC= 8, the frequency domain offset value parameter of the fifth transmission comb 601 is 0, and the frequency domain offset value parameter of the sixth transmission comb 602 is 1, the fifth transmission comb 601 and the sixth transmission comb 602 each occupy four consecutive slot symbols 8-11, adjacent subcarriers in each transmission comb are spaced apart by 7 subcarriers, the subcarriers occupied by the fifth transmission comb 601 include subcarrier 0 and subcarrier 8 of the first PRB and subcarrier 4 of the second PRB, and the subcarriers occupied by the sixth transmission comb 602 include subcarrier 7 of the first PRB and subcarrier 3 and subcarrier 11 of the second PRB, and for the six subcarriers corresponding to the two transmission combs, the two corresponding subcarriers are spaced apart by 6 subcarriers, that is, the two transmission combs comply with the principle of maximum spacing.

[0062] 4) Other predefined principles.

[0063] Other predefined rules may determine the format of other frequency domain offset parameters depending on the protocol defined.

[0064] In short, the method for transmitting an SRS provided by this embodiment supports SRS transmission in multiple transmission combs of different frequency domain dimensions of multiple antenna port groups.

[0065] In some embodiments, at least two antenna port groups may be mapped to at least two transmit combs with the same frequency domain offset parameters of the transmit combs, and as shown in FIG. 7, step 220 may be realized by step 720 as follows: Step 720: map the SRSs corresponding to the at least two antenna port groups to physical resources corresponding to the at least two transmission combs in a time domain dimension, and simultaneously transmit the SRSs corresponding to the at least two antenna port groups.

[0070] Exemplarily, the time domain positions of at least two transmission combs may be located in the same slot or in different slots, for example, the seventh transmission comb 801 and the eighth transmission comb 802 in FIG.

[0071] Optionally, the frequency domain offset value parameters of the transmission combs corresponding to the at least two antenna port groups are set for the terminal by the network device. Exemplarily, the terminal receives one frequency domain offset value parameter of the transmission comb corresponding to the at least two antenna port groups; that is, the network device sets one frequency domain offset value parameter of the transmission comb for the terminal.

number

[0072] In short, the method for transmitting an SRS provided by this embodiment supports SRS transmission in multiple transmission combs of different time domain dimensions for multiple antenna port groups.

[0073] In some embodiments, the at least two antenna port groups are obtained by sequentially grouping the eight antenna ports according to port numbers, as shown in Figure 3, one antenna port group includes port 0, port 1, port 2, and port 3, and another antenna port group includes port 4, port 5, port 6, and port 7.

[0074] In some other embodiments, the at least two antenna port groups are obtained by grouping the eight antenna ports according to port number into a group including ports with odd port numbers and a group including ports with even port numbers, as shown in Figure 5, one antenna port group includes port 0, port 2, port 4, and port 6, and another antenna port group includes port 1, port 3, port 5, and port 7.

[0075] In some other embodiments, the at least two antenna port groups are obtained by sequentially grouping ports with odd port numbers among the eight antenna ports to obtain at least two first antenna port groups, and sequentially grouping ports with even port numbers among the eight antenna ports to obtain at least two second antenna port groups.

Illustratively, the transmission comb parameter set in the SRS resource is 12, and the frequency domain offset value parameter of the transmission comb includes {5, 7, 9, 11}, so there are four transmission combs with the same transmission comb structure.

[0076] As shown in FIG. 10, the ports with even port numbers among the eight antenna ports include port 0, port 2, port 4, and port 6; the ports with odd port numbers among the eight antenna ports include port 1, port 3, port 5, and port 7; after grouping the eight antenna ports in the time domain, one first antenna port group includes port 1 and port 3, another first antenna port group includes port 5 and port 7, one second antenna port group includes port 0 and port 2, and another second antenna port group includes port 4 and port 6.

[0077] In some other embodiments, the at least two antenna port groups are obtained by grouping according to a combination scheme predefined by a protocol, for example, port 0, port 1, port 6, and port 7 are one group of antenna port groups, and port 2, port 3, port 4, and port 5 are another group of antenna port groups predefined by a protocol.

[0078] In short, the method for transmitting an SRS provided by this embodiment supports multiple port combinations to transmit an SRS on multiple transmission combs.
