DETAILED DESCRIPTION OF THE INVENTION

[0016] Illustrative examples are described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, like numerals in different drawings refer to the same or similar elements unless otherwise indicated. The embodiments described in the following illustrative examples do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application as set forth in the appended claims.

[0017] 1 illustrates a block diagram of a communication system provided in accordance with one exemplary embodiment of the present disclosure. The communication system may include an access network 12 and a user terminal 14.

[0018] The access network 12 includes several network devices 120. A network device may be a base station, which is a device located in an access network and providing wireless communication functions for user terminals (abbreviated as "terminals") 14. Base stations may include various types of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different radio access technologies, the name of a device providing base station functionality may differ. For example, in a Long Term Evolution (LTE) system, it is called an eNodeB or eNB, and in a 5G New Radio (NR) system, it is called a gNodeB or gNB. As communication technologies evolve, the term "base station" may change. For ease of explanation of the embodiments of the present disclosure, devices providing wireless communication functions for the user terminals 14 will be collectively referred to as network devices.

[0019] The user terminal 14 may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, each having wireless communication capabilities, as well as various forms of user devices, mobile stations (MS), terminal devices, etc. For ease of explanation, the above-mentioned devices are collectively referred to as a user terminal. The network device 120 and the user terminal 14 communicate with each other via a specific air interface technology, such as the Uu interface.

[0020] Illustratively, there are two types of communication scenarios between the network device 120 and the user terminal 14: uplink communication scenario and downlink communication scenario. Uplink communication refers to transmitting signals to the network device 120, and downlink communication refers to transmitting signals to the user terminal 14.

[0021] The technical solutions of the embodiments of the present disclosure include a Global System of Mobile Communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, an Advanced Long Term Evolution (LTE-A) system, a New Radio (NR) system, an evolution system of the NR system, an LTE-based access to Unlicensed spectrum (LTE-U) system, an NR-U system, a Universal Mobile Telecommunication System (UMTS), a Worldwide Interoperability for Microwave Access (WIM) system, a LTE-based access to Unlicensed spectrum (LTE-U) system, a NR-U system, a Universal Mobile Telecommunication System (UMTS), a LTE-based access to Unlicensed spectrum (LTE-U), a NR-U system, a UMTS ... The present invention may be applied to various communication systems such as WiMAX (Wireless Access) communication systems, Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next generation communication systems, or other communication systems.

[0022] Conventional communication systems typically support a limited number of connections, which are easily realized. However, with the development of communication technology, mobile communication systems now 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. The embodiments of the present application can also be applied to these communication systems.

[0023] 2 shows a flowchart 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 SRS resources, where the SRS resources include eight antenna ports;

[0024] Exemplarily, the terminal receives SRS resource configuration information sent by the 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 states that the number of SRS antenna ports is:

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 for the SRS.

number

number

[0027] Step 220: Map SRSs corresponding to at least two antenna port groups to physical resources corresponding to different transmission combs, and simultaneously transmit SRSs corresponding to 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 measuring uplink channel quality, the UE maps one SRS resource to the same physical resource (PR). For example, the physical resource refers to contiguous carrier resources in the frequency domain, and one physical resource block (PRB) corresponds to 12 contiguous carriers in the frequency domain and one slot in the time domain.

[0029] For example, the uplink channel may include at least one of a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH). The UE may map one SRS resource to a physical resource of the PUCCH and / or the PUSCH.

[0030] For example, the terminal maps one SRS resource to the same physical resource based on the configuration information, where the configuration information includes at least one parameter among the following parameters: Transmission comb parameter k TC ; Frequency domain offset parameter

number

number

number

[0031] The transmit comb parameter is used to indicate the comb structure in the frequency domain of the SRS resource, i.e., the SRS resource is not mapped onto consecutive subcarriers. The transmit comb parameter is denoted by comb, where comb=k. TC , k TC The value of is a positive integer, and there is a distance (k TC −1) subcarriers apart, i.e., the distance between adjacent resource elements (RE) in the SRS resource is (k TC-1) subcarriers are spaced apart. For example, if comb=8, adjacent RE resources in one SRS resource are spaced 7 subcarriers apart. 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 is a non-negative integer smaller than the transmit 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 the sequence cyclic shift. An antenna port is a logical transmission channel defined by a reference signal, and the antenna port is mapped to a physical antenna for signal transmission. The time domain position of the transmit comb is used to indicate which symbols the transmit comb occupies in a slot.

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

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

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

[0035] Illustratively, 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 and Antenna switching and and at least one of: a non-codebook;

[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] Exemplarily, 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, and the frequency domain offset value parameter of the second transmission comb 302 is 1. Adjacent subcarriers in each transmission comb are spaced one subcarrier apart. The subcarriers occupied by the first transmission comb 301 are subcarrier 0, subcarrier 2, subcarrier 4, subcarrier 6, and subcarrier 7. 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. 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] Illustratively, the maximum value of the cyclic shift parameter of the transmit comb corresponding to at least two antenna port groups is:

number

number

number

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

number

[0041] For example, 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 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.

number

number

[0045] In some other embodiments, the transmit comb parameter k TC is equal to 8 or 12, only one SRS resource can be mapped to one PRB, and therefore 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, which avoids the measurement result of uplink channel quality being unrepresentative due to a small number of RE resources.

[0046] In short, in the SRS transmission method 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 SRS resource configuration information, it 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 this method is used to support the realization of related functions when the terminal uses eight transmit antenna ports, for example, to support codebook-based channel quality detection when the terminal uses eight transmit antenna ports, or to support non-codebook-based channel quality detection when the terminal uses eight transmit antenna ports, or to support channel quality detection during antenna switching when the terminal uses eight transmit 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 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 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, transmit comb parameters k of the transmit combs corresponding to the 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.

[0050] Optionally, frequency domain offset value parameters of the transmit combs corresponding to the at least two antenna port groups.

number

number

[0051] Optionally, some or all of the frequency domain offset value parameters of the transmission comb are configured for the terminal by a network device. Illustratively, the terminal receives a first frequency domain offset value parameter of a transmission comb corresponding to a first antenna port group, where the first antenna port group is one of at least two antenna port groups, and calculates other frequency domain offset value parameters of transmission combs corresponding to other antenna port groups based on the first frequency domain offset value parameter, where the other antenna port groups are antenna port groups 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 the transmit combs corresponding to at least two antenna port groups.

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

number

number

[0054] Alternatively, the terminal may calculate the other frequency domain offset value parameters according to the principle of adjacent transmission combs, or according to the principle of uniform distribution, or according to the principle of maximum spacing, or according to other predefined principles. Exemplarily, the four types of determining principles for the other frequency domain offset value parameters are described below: 1) The principle of adjacent transmission combs.

[0055] Frequency domain offset parameters for each port corresponding to other transmission combs

number

number

number

[0056] Exemplarily, as shown in FIG. 3, the subcarriers corresponding to the first transmission comb 301 and the second transmission comb 302 are adjacent to each other.

[0057] 2) The principle of uniform distribution.

[0058] Frequency domain offset parameters for each port corresponding to other transmission combs

number

number

[0059] 3) The principle of maximum spacing.

[0060] The difference in frequency domain offset parameters between connected transmission combs is maximal. For example, k TC If = 4, the first frequency domain offset value parameter is 0 and the other frequency domain offset value parameter is 3, thus complying with the principle of maximum spacing between at least two transmission combs.

[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 to 11. Adjacent subcarriers on each transmission comb are spaced 7 subcarriers apart. 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. 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. For the six subcarriers corresponding to the two transmission combs, the spacing between the two corresponding subcarriers is six subcarriers, which conforms to the principle of maximum spacing between the two transmission combs.

[0062] 4) Other predefined principles.

[0063] Other predefined principles may determine the format of other frequency domain offset value 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 for 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 implemented 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.

[0066] There is a one-to-one correspondence between the antenna port groups and the transmit combs. Optionally, the time-domain positions of the transmit combs corresponding to at least two antenna port groups are different and adjacent.

[0067] Optionally, transmit comb parameters k of the transmit combs corresponding to the at least two antenna port groups. TC is the same.

[0068] Optionally, frequency domain offset value parameters of the transmit combs corresponding to the at least two antenna port groups.

number

number

[0069] For example, as shown in FIG. 8 , a seventh transmission comb 801 and an eighth transmission comb 802 are configured in the SRS resource, the transmission comb parameters of the seventh transmission comb 801 and the eighth transmission comb 802 are both 8, and the frequency domain offset value parameters of the seventh transmission comb 801 and the eighth transmission comb 802 are both 7. The seventh transmission comb 801 and the eighth transmission comb 802 are located on the same subcarrier, including subcarrier 7 in the first PRB and subcarrier 3 and subcarrier 11 in the second PRB. The seventh transmission comb 801 and the eighth transmission comb 802 are located at different time domain positions, with the seventh transmission comb 801 located on slot symbol 8 and symbol 9, and the eighth transmission comb 802 located on slot symbol 10 and symbol 11. The time domain positions of the seventh transmission comb 801 and the eighth transmission comb 802 are adjacent to each other.

[0070] Illustratively, the time-domain positions of at least two transmit combs can be located in the same slot or different slots, for example, the seventh transmit comb 801 and the eighth transmit 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 configured for the terminal by the network device. Illustratively, 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 configures 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, where 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, as shown in FIG.

[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 eight antenna ports with odd-numbered port numbers to obtain at least two first antenna port groups, and sequentially grouping eight antenna ports with even-numbered port numbers to obtain at least two second antenna port groups. As shown in FIG. 9 , after grouping the eight antenna ports in the frequency 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. Illustratively, the transmit comb parameter set for the SRS resource is 12, and the frequency domain offset value parameter of the transmit comb includes {5, 7, 9, 11}. Therefore, there are four transmit combs with the same transmit 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 predefined by a protocol, 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 SRS transmission method provided by this embodiment supports multiple port combinations to transmit SRS on multiple transmission combs.

[0079] FIG. 11 shows a flowchart of a method for receiving an SRS provided by one exemplary embodiment of the present disclosure, the method being applied to a network device of the communication system shown in FIG. 1 , the method including the following steps: Step 1010: Send configuration information of SRS resources, where the SRS resources include 8 antenna ports.

[0080] The network device configures and transmits SRS resource configuration information for the terminal.

[0081] When at least two transmission combs configured by the SRS resource configuration information are located in different frequency domain dimensions, the SRS resource configuration information is a time domain position of a transmit comb corresponding to at least two antenna port groups; One transmit comb parameter corresponding to at least two antenna port groups

number

[0082] When at least two transmission combs configured by the SRS resource configuration information are located in different time domain dimensions, the SRS resource configuration information at least two adjacent time domain positions of the transmit comb corresponding to at least two antenna port groups; One transmit comb parameter corresponding to at least two antenna port groups

number

[0083] When one cyclic shift parameter is configured for at least two antenna port groups, the cyclic shift parameter is used to determine the cyclic shift parameters of all antenna ports in the at least two antenna port groups, and when one cyclic shift parameter is configured for each antenna port group, the cyclic shift parameter corresponding to one antenna port group is used to determine the cyclic shift parameters of all antenna ports in the antenna port group.

[0084] Alternatively, the at least two antenna port groups are obtained by sequentially grouping the eight antenna ports according to their port numbers, or the at least two antenna port groups are obtained by grouping the eight antenna ports according to their port numbers into a group including ports with odd port numbers and a group including ports with even port numbers, or the at least two antenna port groups are obtained by grouping according to a combination scheme predefined by a protocol, or 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.

[0085] For example, the number of antenna ports of the SRS is

[0088] For example, the maximum number of cyclic shift parameters supported by the transmission comb parameters is 12;

number

[0089] Illustratively, the function of the SRS resource is one of codebook, antenna switching, and non-codebook.

[0090] Illustratively, the network device transmits SRS distribution information to the terminal through higher layer signaling.
