[0037] In related technologies, SRS resources include periodic SRS resources, semi-persistent SRS resources, and aperiodic SRS resources.

[0038] Terminal devices typically support multiple antenna switching transmission methods for SRS. For example, terminal devices may support one or more of the following six groups of antenna switching transmission methods for SRS:

[0039] Group 1: 1 Transmitting antenna, 2 Receiver antenna 1T2R and 2 Transmitting antenna, 4 Receiver antenna 2T4R;

[0040] The second group consists of 1T2R and 1 transmitting antenna, 4 receiving antennas, and 1T4R.

[0041] Group 3: 1T2R and the transmitting antenna equals the receiving antenna T=R;

[0042] Group 4: 1T4R and T=R;

[0043] Group 5: 1T2R, 1T4R, and T=R;

[0044] Group 6: 1T2R, 1T4R, and 2T4R.

[0045] In the above-mentioned antenna switching transmission methods for SRS, the letter T represents transmission, and the number before the letter T represents the number of transmitting antennas; the letter R represents reception, and the number immediately preceding the letter R represents the number of receiving antennas; T=R means that the number of transmitting antennas and the number of receiving antennas are equal.

[0046] The Chinese text preceding the antenna switching transmission methods used in SRS above is for explanatory purposes only. For example, "1 transmitting antenna 2 receiving antenna" before 1T2R is an explanation of 1T2R, and "2 transmitting antenna 4 receiving antenna" before 2T4R is an explanation of 2T4R; etc., and does not constitute a specific limitation.

[0047] Among the various antenna switching transmission methods supported by the terminal device for SRS, there is a minimum number of transmitting antennas, and there is also a minimum number of receiving antennas corresponding to the minimum number of transmitting antennas.

[0048] In related technologies, for different antenna switching transmission methods used for SRS, the network-side equipment configures different SRS resource sets for the terminal.

[0049] (1) For 1T2R antenna switching transmission mode:

[0050] The network-side device can configure a maximum of two SRS resource sets for the terminal, meaning the network-side device can configure 0, 1, or 2 SRS resource sets for the terminal.

[0051] When configuring two SRS resource sets for a terminal on the network side, the resource types of the two SRS resource sets need to be different.

[0052] Network-side devices can configure periodic SRS resource sets, semi-persistent SRS resource sets, and aperiodic SRS resource sets for terminals.

[0053] For example, network-side devices can configure the following for terminals:

[0054] 0 periodic SRS resource sets and 0 semi-persistent SRS resource sets;

[0055] 0 periodic SRS resource sets and 1 semi-persistent SRS resource set;

[0056] One periodic SRS resource set and zero semi-persistent SRS resource sets;

[0057] One periodic SRS resource set and one semi-persistent SRS resource set;

[0058] 0 periodic SRS resource sets and 0 aperiodic SRS resource sets;

[0059] 0 periodic SRS resource sets and 1 non-periodic SRS resource set;

[0060] One periodic SRS resource set and zero non-periodic SRS resource sets;

[0061] One periodic SRS resource set and one non-periodic SRS resource set;

[0062] 0 semi-persistent SRS resource sets and 0 aperiodic SRS resource sets;

[0063] 0 semi-persistent SRS resource sets and 1 aperiodic SRS resource set;

[0064] One semi-persistent SRS resource set and zero aperiodic SRS resource sets;

[0065] One semi-persistent SRS resource set and one aperiodic SRS resource set.

[0066] Each SRS resource set is associated with two SRS resources, and each SRS resource is associated with one SRS port.

[0067] (2) For the 2T4R antenna switching transmission method:

[0068] The network-side device can configure a maximum of two SRS resource sets for the terminal, meaning the network-side device can configure 0, 1, or 2 SRS resource sets for the terminal.

[0069] When configuring two SRS resource sets for a terminal on the network side, the resource types of the two SRS resource sets need to be different.

[0070] Network-side devices can configure periodic SRS resource sets, semi-persistent SRS resource sets, and aperiodic SRS resource sets for terminals.

[0071] For example, network-side devices can configure the following for terminals:

[0072] 0 periodic SRS resource sets and 0 semi-persistent SRS resource sets;

[0073] 0 periodic SRS resource sets and 1 semi-persistent SRS resource set;

[0074] One periodic SRS resource set and zero semi-persistent SRS resource sets;

[0075] One periodic SRS resource set and one semi-persistent SRS resource set;

[0076] 0 periodic SRS resource sets and 0 aperiodic SRS resource sets;

[0077] 0 periodic SRS resource sets and 1 non-periodic SRS resource set;

[0078] One periodic SRS resource set and zero non-periodic SRS resource sets;

[0079] One periodic SRS resource set and one non-periodic SRS resource set;

[0080] 0 semi-persistent SRS resource sets and 0 aperiodic SRS resource sets;

[0081] 0 semi-persistent SRS resource sets and 1 aperiodic SRS resource set;

[0082] One semi-persistent SRS resource set and zero aperiodic SRS resource sets;

[0083] One semi-persistent SRS resource set and one aperiodic SRS resource set.

[0084] Each SRS resource set is associated with two SRS resources, and each SRS resource is associated with one SRS port.

[0085] (3) For the antenna switching transmission mode of 1T4R:

[0086] 1. Network-side devices can configure periodic SRS resource sets and semi-persistent SRS resource sets for terminals. Network-side devices can configure 0 SRS resource sets or 1 SRS resource set for a terminal, that is, at most 1 periodic SRS resource set or at most 1 semi-persistent SRS resource set for a terminal.

[0087] Each SRS resource set is associated with 4 SRS resources, and each SRS resource is associated with 1 SRS port.

[0088] 2. Network-side devices can configure non-periodic SRS resource sets for terminals. Network-side devices can configure 0 or 2 SRS resource sets for terminals, that is, a maximum of 2 non-periodic SRS resource sets can be configured for terminals. The 2 SRS resource sets are associated with a total of 4 SRS resources, and each SRS resource is associated with 1 SRS port.

[0089] For example, network-side devices can configure the following for terminals:

[0090] 0 periodic SRS resource sets and 0 aperiodic SRS resource sets;

[0091] 0 semi-persistent SRS resource sets and 0 aperiodic SRS resource sets;

[0092] 0 periodic SRS resource sets and 2 non-periodic SRS resource sets;

[0093] 0 semi-persistent SRS resource sets and 2 aperiodic SRS resource sets;

[0094] One periodic SRS resource set and two non-periodic SRS resource sets;

[0095] One semi-persistent SRS resource set and two aperiodic SRS resource sets.

[0096] (4) Antenna switching transmission methods for 1T1R, 2T2R, and 4T4R:

[0097] The network-side device can configure a maximum of two SRS resource sets for the terminal, meaning the network-side device can configure 0, 1, or 2 SRS resource sets for the terminal.

[0098] When the network-side device configures two SRS resource sets for the terminal, the resource types of the two SRS resource sets can be the same.

[0099] Network-side devices can configure periodic SRS resource sets, semi-persistent SRS resource sets, and aperiodic SRS resource sets for terminals.

[0100] For example, network-side devices can configure the following for terminals:

[0101] 0-period SRS resource set;

[0102] One cycle of SRS resource set;

[0103] Two-period SRS resource sets;

[0104] 0 semi-persistent SRS resource sets;

[0105] One semi-persistent SRS resource set;

[0106] Two semi-persistent SRS resource sets;

[0107] 0 aperiodic SRS resource sets;

[0108] One aperiodic SRS resource set;

[0109] Two aperiodic SRS resource sets;

[0110] One periodic SRS resource set and one non-periodic SRS resource set;

[0111] One periodic SRS resource set and one semi-persistent SRS resource set;

[0112] One semi-persistent SRS resource set and one aperiodic SRS resource set.

[0113] The configuration enhancements for periodic SRS resource sets and semi-persistent SRS resource sets are as follows:

[0114] (1) Support for antenna switching capability A (that is, the capability to support a maximum of 1 cycle SRS resource set + 2 half-persistent SRS resource sets);

[0115] For all antenna switching transmission modes xTyR:

[0116] It supports configuring up to one periodic SRS resource set + two semi-persistent SRS resource sets;

[0117] For example, network-side devices can configure the following for terminals:

[0118] 0 periodic SRS resource sets + 0 semi-persistent SRS resource sets;

[0119] 0 periodic SRS resource sets + 1 semi-persistent SRS resource set;

[0120] 0 periodic SRS resource sets + 2 semi-persistent SRS resource sets;

[0121] One periodic SRS resource set + 0 semi-persistent SRS resource sets;

[0122] One periodic SRS resource set + one semi-persistent SRS resource set;

[0123] One periodic SRS resource set + two semi-persistent SRS resource sets.

[0124] For A, which does not support antenna switching capability;

[0125] For the antenna switching transmission mode xTyR, when y>4, it supports configuring a maximum of 1 periodic SRS resource set + 1 semi-persistent SRS resource set;

[0126] For antenna switching transmission mode xTyR, when y <= 4:

[0127] For 1T2R and 2T4R, a maximum of two SRS resource sets can be configured. The resource types of the two SRS resource sets need to be different, and non-periodic SRS resource sets need to be considered.

[0128] For 1T1R, 2T2R, and 4T4R, a maximum of two SRS resource sets can be configured, among which non-periodic SRS resource sets need to be considered.

[0129] For 1T4R, a maximum of one periodic SRS resource set or one semi-persistent SRS resource set can be configured, and non-periodic SRS resource sets are not considered.

[0130] (2) Supports antenna switching capability B, which means supports 1T4R configuration of 4 SRS resource sets and 1T2R / 2T4R configuration of 2 SRS resource sets.

[0131] For antenna switching transmission mode xTyR, this capability is not applicable when y>4;

[0132] For the antenna switching transmission mode xTyR, when y<4, it supports configuring 4 SRS resource sets for 1T4R and 2 SRS resource sets for 1T2R / 2T4R.

[0133] For option B, which does not support antenna switching capability,

[0134] For antenna switching transmission mode xTyR, this capability is not applicable when y>4;

[0135] For the antenna switching transmission mode xTyR, when y < 4, the configuration quantity is not increased, that is, the configuration is performed according to the Rel-15 rules.

[0136] For 1T2R and 2T4R, a maximum of two SRS resource sets can be configured. The resource types of the two SRS resource sets need to be different, and the impact of the number of periodic SRS resource sets and semi-persistent SRS resource sets needs to be considered.

[0137] For 1T1R, 2T2R, and 4T4R, a maximum of two SRS resource sets can be configured, where the impact of the number of periodic SRS resource sets and semi-persistent SRS resource sets needs to be considered.

[0138] For 1T4R, configure 0 or 2 aperiodic SRS resource sets, without considering the impact of the number of periodic SRS resource sets and semi-persistent SRS resource sets.

[0139] Currently, the terminal supports antenna switching capabilities A and B, and is subject to Rel-15 antenna switching configuration limitations. For antenna switching type xTyR, when y <= 4, antenna switching capability A only considers enhancing the capabilities of periodic and semi-persistent SRS, while antenna switching capability B only considers enhancing the capabilities of aperiodic SRS. When antenna switching capability A or B is not supported, the Rel-15 antenna switching configuration limitations are used, which simultaneously consider the number of periodic, semi-persistent, and aperiodic SRS resource sets. Therefore, when the terminal does not support antenna switching capability A or B, the network side and the terminal cannot obtain the configuration limitations for different SRS resource types based on existing protocols. If the understandings of the two sides are inconsistent, when the number of resources configured by the network side exceeds the number of resources understood by the terminal, the terminal cannot determine whether to continue transmitting the resources configured by the network side or ignore them as a configuration error.

[0140] The SRS resource configuration method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0141] This application provides an SRS resource configuration method, such as... Figure 2 As shown, it includes:

[0142] Step 101: The network-side device receives the antenna switching capabilities for SRS reported by the terminal;

[0143] Step 102: The network-side device determines the number of SRS resource sets configured for the terminal based on the antenna switching capability;

[0144] Step 103: The network-side device sends SRS configuration information to the terminal, wherein the SRS configuration information indicates the number of SRS resource sets.

[0145] In this embodiment, the network-side device determines the number of SRS resource sets configured by the terminal based on the antenna switching capabilities reported by the terminal. This ensures that the network-side device and the terminal have the same understanding of the antenna switching capabilities reported by the terminal, preventing the number of SRS resource sets configured by the network-side device from exceeding the antenna switching capabilities that the terminal can support, and ensuring that the configured SRS resources can be sent and received normally.

[0146] In some embodiments, the antenna switching capability includes at least one of a first antenna switching capability (i.e., antenna switching capability A) and a second antenna switching capability (i.e., antenna switching capability B). The first antenna switching capability supports at most N periodic SRS resource sets and at most M semi-persistent SRS resource sets, and the second antenna switching capability supports at most K aperiodic SRS resource sets. The number of SRS resource sets configured for the terminal by the network-side device based on the antenna switching capability includes at least one of the following:

[0147] When the terminal reports support for the first antenna switching capability, the number of periodic SRS resource sets configured by the terminal is determined according to the maximum number N of periodic SRS resource sets supported by the first antenna switching capability, where N is an integer.

[0148] When the terminal reports support for the first antenna switching capability, the number of semi-persistent SRS resource sets configured by the terminal is determined according to the maximum number M of the semi-persistent SRS resource sets supported by the first antenna switching capability, where M is an integer.

[0149] When the terminal reports support for the second antenna switching capability, the number of aperiodic SRS resource sets configured for the terminal is determined based on the maximum number K of aperiodic SRS resource sets supported by the second antenna switching capability, where K is an integer.

[0150] In this way, regardless of whether the terminal supports the first antenna switching capability, the second antenna switching capability, or both, the network-side device and the terminal can have the same understanding of the antenna switching capability reported by the terminal. This prevents the number of SRS resource sets configured by the network-side device from exceeding the antenna switching capability that the terminal can support, and ensures that the configured SRS resources can be sent and received normally.

[0151] In some embodiments, the first antenna switching capability supports up to one periodic SRS resource set and / or up to two half-persistent SRS resource sets; the second antenna switching capability supports four aperiodic SRS resource sets configured for antenna switching transmission mode with one transmit antenna and four receive antennas, two aperiodic SRS resource sets configured for antenna switching transmission mode with one transmit antenna and two receive antennas, and two aperiodic SRS resource sets configured for antenna switching transmission mode with two transmit antennas and four receive antennas.

[0152] In some embodiments, if the terminal reports support for the first antenna switching capability but not for the second antenna switching capability, then the configuration quantity limits for the periodic SRS resource set and the semi-persistent SRS resource set are obtained based on the first antenna switching capability, while the configuration quantity limit for the non-periodic SRS resource set is obtained based on the configuration quantity limit for the antenna switching resource set in Rel-15. The network-side device configures the SRS resource set for the terminal using any of the following first methods:

[0153] When the terminal supports antenna switching transmission mode with 1 transmitting antenna and 2 receiving antennas and / or antenna switching transmission mode with 2 transmitting antennas and 4 receiving antennas, the terminal is configured with at most 2 semi-persistent SRS resource sets, at most 1 periodic SRS resource set, and at most 1 aperiodic SRS resource set.

[0154] When the terminal supports antenna switching transmission mode with 1 transmitting antenna and 4 receiving antennas, the terminal is configured with up to 2 semi-persistent SRS resource sets, up to 1 periodic SRS resource set, and 0 or 2 aperiodic SRS resource sets.

[0155] When the terminal supports antenna switching transmission modes where the number of transmitting antennas is equal to the number of receiving antennas (including antenna switching transmission modes with 1 transmitting antenna and 1 receiving antenna, antenna switching transmission modes with 2 transmitting antennas and 2 receiving antennas, and / or antenna switching transmission modes with 4 transmitting antennas and 4 receiving antennas), the terminal is configured with at most 2 semi-persistent SRS resource sets, at most 2 periodic SRS resource sets, and at most 2 aperiodic SRS resource sets.

[0156] In this way, even if the terminal supports the first antenna switching capability but not the second antenna switching capability, the network-side device and the terminal can have the same understanding of the antenna switching capability reported by the terminal. This prevents the number of SRS resource sets configured by the network-side device from exceeding the antenna switching capability that the terminal can support, and ensures that the configured SRS resources can be sent and received normally.

[0157] In some embodiments, the terminal reports support for the first antenna switching capability but not for the second antenna switching capability. When using the first method, if the terminal supports antenna switching transmission mode with 1 transmitting antenna and 2 receiving antennas and / or antenna switching transmission mode with 2 transmitting antennas and 4 receiving antennas,

[0158] The network-side device configures two semi-persistent SRS resource sets for the terminal, and the network-side device configures up to four SRS resource sets for the terminal; or

[0159] The network-side device configures up to three SRS resource sets for the terminal; or

[0160] The network-side device configures up to four SRS resource sets for the terminal.

[0161] In a specific example, when the terminal supports antenna switching transmission modes with 1 transmitting antenna and 2 receiving antennas and / or 2 transmitting antennas and 4 receiving antennas, the network-side device supports configuring up to 3 SRS resource sets for the terminal. Besides being able to configure up to 2 semi-persistent SRS resource sets simultaneously, when configuring multiple SRS resource sets for the terminal, the resource types of the configured SRS resource sets must be different. The SRS resource sets configured by the network-side device for the terminal are selected from a first combination, which includes at least one of the following:

[0162] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0163] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0164] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 0 aperiodic SRS resource sets;

[0165] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 1 aperiodic SRS resource set;

[0166] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0167] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0168] One periodic SRS resource set, zero semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0169] One periodic SRS resource set, zero semi-persistent SRS resource sets, and one aperiodic SRS resource set;

[0170] One periodic SRS resource set, one semi-persistent SRS resource set, and zero aperiodic SRS resource sets;

[0171] One periodic SRS resource set, one semi-persistent SRS resource set, and one non-periodic SRS resource set;

[0172] One periodic SRS resource set, two semi-persistent SRS resource sets, and zero aperiodic SRS resource sets.

[0173] Specifically, when the terminal supports antenna switching transmission modes with 1 transmitting antenna and 2 receiving antennas and / or 2 transmitting antennas and 4 receiving antennas, the network-side device also supports configuring up to 4 SRS resource sets for the terminal. Besides being able to configure up to 2 semi-persistent SRS resource sets simultaneously, when configuring multiple SRS resource sets for the terminal, the resource types of the configured SRS resource sets must be different. Furthermore, configuring up to 4 SRS resource sets for the terminal is supported only when 2 semi-persistent SRS resource sets are configured simultaneously.

[0174] The SRS resource set configured by the network-side device for the terminal is selected from a first combination, which includes at least one of the following:

[0175] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0176] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0177] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 0 aperiodic SRS resource sets;

[0178] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 1 aperiodic SRS resource set;

[0179] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0180] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0181] One periodic SRS resource set, zero semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0182] One periodic SRS resource set, zero semi-persistent SRS resource sets, and one aperiodic SRS resource set;

[0183] One periodic SRS resource set, one semi-persistent SRS resource set, and zero aperiodic SRS resource sets;

[0184] One periodic SRS resource set, one semi-persistent SRS resource set, and one non-periodic SRS resource set;

[0185] One periodic SRS resource set, two semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0186] One periodic SRS resource set, two semi-persistent SRS resource sets, and one non-periodic SRS resource set.

[0187] In some embodiments, the terminal reports support for the first antenna switching capability but not for the second antenna switching capability. When using the first method, if the terminal supports an antenna switching transmission mode with 1 transmitting antenna and 4 receiving antennas, the network-side device supports configuring up to 5 SRS resource sets for the terminal.

[0188] The SRS resource set configured by the network-side device for the terminal is selected from a first combination, which includes at least one of the following:

[0189] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0190] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 2 aperiodic SRS resource sets;

[0191] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 0 aperiodic SRS resource sets;

[0192] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 2 aperiodic SRS resource sets;

[0193] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0196] One periodic SRS resource set, zero semi-persistent SRS resource sets, and two aperiodic SRS resource sets;

[0197] One periodic SRS resource set, one semi-persistent SRS resource set, and zero aperiodic SRS resource sets;

[0198] One periodic SRS resource set, one semi-persistent SRS resource set, and two aperiodic SRS resource sets;

[0199] One periodic SRS resource set, two semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0200] One periodic SRS resource set, two semi-persistent SRS resource sets, and two aperiodic SRS resource sets.

[0201] In some embodiments, the terminal reports support for the first antenna switching capability but not for the second antenna switching capability. When the first method is used,

[0202] In a specific example, when the terminal supports antenna switching transmission modes where the number of transmitting antennas is equal to the number of receiving antennas (including antenna switching transmission modes with 1 transmitting antenna and 1 receiving antenna, antenna switching transmission modes with 2 transmitting antennas and 2 receiving antennas, and / or antenna switching transmission modes with 4 transmitting antennas and 4 receiving antennas), the network-side device supports configuring a maximum of 3 SRS resource sets for the terminal; or, it only supports configuring a maximum of 3 SRS resource sets for the terminal when the network-side device has configured 2 semi-persistent SRS resource sets for the terminal; or, it only supports configuring a maximum of 3 SRS resource sets for the terminal when the network-side device has configured at least 1 semi-persistent SRS resource set for the terminal.

[0203] The SRS resource set configured by the network-side device for the terminal is selected from a first combination, which includes at least one of the following:

[0204] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0205] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0206] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 2 aperiodic SRS resource sets;

[0207] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 0 aperiodic SRS resource sets;

[0208] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 1 aperiodic SRS resource set;

[0209] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0210] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0211] One periodic SRS resource set, zero semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0212] One periodic SRS resource set, zero semi-persistent SRS resource sets, and one aperiodic SRS resource set;

[0213] One periodic SRS resource set, one semi-persistent SRS resource set, and zero aperiodic SRS resource sets;

[0214] One periodic SRS resource set, two semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0215] Two periodic SRS resource sets, zero semi-persistent SRS resource sets, and zero aperiodic SRS resource sets.

[0216] The network-side device supports configuring a maximum of three SRS resource sets for a terminal only when it has configured two semi-persistent SRS resource sets for the terminal. The SRS resource sets configured by the network-side device for the terminal are selected from a first combination, which includes at least one of the following:

[0217] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0218] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0219] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 2 aperiodic SRS resource sets;

[0220] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 0 aperiodic SRS resource sets;

[0221] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 1 aperiodic SRS resource set;

[0222] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 2 aperiodic SRS resource sets;

[0223] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0224] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0225] One periodic SRS resource set, zero semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0226] One periodic SRS resource set, zero semi-persistent SRS resource sets, and one aperiodic SRS resource set;

[0227] One periodic SRS resource set, one semi-persistent SRS resource set, and zero aperiodic SRS resource sets;

[0228] One periodic SRS resource set, one semi-persistent SRS resource set, and one non-periodic SRS resource set;

[0229] One periodic SRS resource set, two semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0230] Two periodic SRS resource sets, zero semi-persistent SRS resource sets, and zero aperiodic SRS resource sets.

[0231] In some embodiments, if the terminal reports that it does not support the first antenna switching capability but supports the second antenna switching capability, then the configuration quantity limit of the aperiodic SRS resource set is obtained based on the second antenna switching capability, while the configuration quantity limits of the periodic SRS resource set and the semi-persistent SRS resource set are obtained based on the configuration quantity limit of the antenna switching resource set in Rel-15. The network-side device configures the SRS resource set for the terminal using any of the following second methods:

[0232] When the terminal supports antenna switching transmission mode with 1 transmitting antenna and 2 receiving antennas and / or antenna switching transmission mode with 2 transmitting antennas and 4 receiving antennas, the terminal is configured with at most 1 semi-persistent SRS resource set, at most 1 periodic SRS resource set, and at most 2 aperiodic SRS resource sets.

[0233] When the terminal supports antenna switching transmission mode with 1 transmitting antenna and 4 receiving antennas, the terminal is configured with at most 1 semi-persistent SRS resource set, at most 1 periodic SRS resource set, and 0, 2 or 4 aperiodic SRS resource sets.

[0234] In this way, even if the terminal does not support the first antenna switching capability but supports the second antenna switching capability, the network-side device and the terminal can have the same understanding of the antenna switching capability reported by the terminal. This prevents the number of SRS resource sets configured by the network-side device from exceeding the antenna switching capability that the terminal can support, and ensures that the configured SRS resources can be sent and received normally.

[0235] In some embodiments, the terminal reports that it does not support the first antenna switching capability but supports the second antenna switching capability. When the second method is adopted, if the terminal supports the antenna switching transmission mode of 1 transmitting antenna and 2 receiving antenna and / or the antenna switching transmission mode of 2 transmitting antennas and 4 receiving antennas, the network-side device configures a periodic SRS resource set and a semi-persistent SRS resource set for the terminal, and configures up to 2 non-periodic SRS resource sets for the terminal.

[0236] In a specific example, when the terminal supports antenna switching transmission mode with 1 transmitting antenna and 2 receiving antennas and / or antenna switching transmission mode with 2 transmitting antennas and 4 receiving antennas, the network-side device supports configuring up to 3 SRS resource sets for the terminal; in addition to configuring up to 2 non-periodic SRS resource sets for the terminal at the same time, when configuring multiple SRS resource sets for the terminal, the resource types of the configured SRS resource sets need to be different.

[0237] In addition, when both periodic SRS resource sets and semi-persistent SRS resource sets are configured for a terminal, a maximum of one non-periodic SRS resource set can be configured for the terminal.

[0238] The SRS resource set configured by the network-side device for the terminal is selected from a first combination, which includes at least one of the following:

[0239] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0240] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0241] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 2 aperiodic SRS resource sets;

[0242] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 0 aperiodic SRS resource sets;

[0243] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 1 aperiodic SRS resource set;

[0244] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 2 aperiodic SRS resource sets;

[0245] One periodic SRS resource set, zero semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0246] One periodic SRS resource set, zero semi-persistent SRS resource sets, and one aperiodic SRS resource set;

[0247] One periodic SRS resource set, zero semi-persistent SRS resource sets, and two aperiodic SRS resource sets;

[0248] One periodic SRS resource set, one semi-persistent SRS resource set, and zero aperiodic SRS resource sets;

[0249] One periodic SRS resource set, one semi-persistent SRS resource set, and one non-periodic SRS resource set.

[0250] In another specific example, when the terminal supports antenna switching transmission mode with 1 transmitting antenna and 2 receiving antennas and / or antenna switching transmission mode with 2 transmitting antennas and 4 receiving antennas, the network-side device supports configuring up to 4 SRS resource sets for the terminal; in addition to configuring up to 2 non-periodic SRS resource sets for the terminal at the same time, when configuring multiple SRS resource sets for the terminal, the resource types of the configured SRS resource sets need to be different.

[0251] The SRS resource set configured by the network-side device for the terminal is selected from a first combination, which includes at least one of the following:

[0252] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0253] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0254] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 2 aperiodic SRS resource sets;

[0255] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 0 aperiodic SRS resource sets;

[0256] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 1 aperiodic SRS resource set;

[0257] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 2 aperiodic SRS resource sets;

[0258] One periodic SRS resource set, zero semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0259] One periodic SRS resource set, zero semi-persistent SRS resource sets, and one aperiodic SRS resource set;

[0260] One periodic SRS resource set, zero semi-persistent SRS resource sets, and two aperiodic SRS resource sets;

[0261] One periodic SRS resource set, one semi-persistent SRS resource set, and zero aperiodic SRS resource sets;

[0262] One periodic SRS resource set, one semi-persistent SRS resource set, and one non-periodic SRS resource set;

[0263] One periodic SRS resource set, one semi-persistent SRS resource set, and two aperiodic SRS resource sets.

[0264] In some embodiments, the terminal reports that it does not support the first antenna switching capability but supports the second antenna switching capability. When the second method is adopted, if the terminal supports an antenna switching transmission mode with 1 transmitting antenna and 4 receiving antennas, the network-side device supports configuring up to 5 SRS resource sets for the terminal. The SRS resource sets configured by the network-side device for the terminal are selected from a first combination, which includes at least one of the following:

[0265] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0266] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 2 aperiodic SRS resource sets;

[0267] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 4 aperiodic SRS resource sets;

[0268] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 0 aperiodic SRS resource sets;

[0269] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 2 aperiodic SRS resource sets;

[0270] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 4 aperiodic SRS resource sets;

[0271] One periodic SRS resource set, zero semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0272] One periodic SRS resource set, zero semi-persistent SRS resource sets, and two aperiodic SRS resource sets;

[0273] One periodic SRS resource set, 0 semi-persistent SRS resource sets, and 4 aperiodic SRS resource sets.

[0274] In some embodiments, the terminal reports support for both the first antenna switching capability and the second antenna switching capability. The terminal does not expect to configure SRS resource sets according to both the first and second antenna switching capabilities simultaneously. The network-side device determines the number of SRS resource sets configured for the terminal based on the antenna switching capability, including:

[0275] The network-side device configures the SRS resource set for the terminal according to either the first method or the second method based on preset rules, wherein the preset rules include any one of the following:

[0276] Configure the SRS resource set for the terminal according to the signaling instructions, selecting either the first method or the second method.

[0277] Based on the configuration of the network-side device, the first method or the second method is selected to configure the SRS resource set for the terminal; or the first method or the second method is randomly selected to configure the SRS resource set for the terminal.

[0278] Configure the SRS resource set for the terminal according to the first method or the second method as agreed in the agreement;

[0279] The SRS resource set is configured for the terminal using either the first method or the second method, based on the priority of the first antenna switching capability and the second antenna switching capability.

[0280] The first method or the second method is selected to configure the SRS resource set for the terminal according to the identification order of the resources or resource sets in the second combination. The second combination is the union of the SRS resource sets supported by the first antenna switching capability and the second antenna switching capability.

[0281] Configuration combinations that do not match the selected capabilities should be ignored or treated as errors.

[0282] In this embodiment, when the terminal supports both the first antenna switching capability and the second antenna switching capability but does not expect to configure the SRS resource set according to both the first antenna switching capability and the second antenna switching capability, the SRS resource set can be configured for the terminal according to a preset rule. This ensures that the network-side device and the terminal have the same understanding of the antenna switching capability reported by the terminal, preventing the number of SRS resource sets configured by the network-side device from exceeding the antenna switching capability that the terminal can support, and ensuring that the configured SRS resources can be sent and received normally.

[0283] Furthermore, SRS resource sets can be configured for the terminal only if the terminal supports antenna switching transmission mode with 1 transmitting antenna and 2 receiving antennas and / or antenna switching transmission mode with 2 transmitting antennas and 4 receiving antennas, according to the preset rules, by selecting the first mode or the second mode.

[0284] In some embodiments, the priority is the terminal reporting, the network-side device configuration, or the protocol agreement.

[0285] In some embodiments, the terminal reports support for both the first antenna switching capability and the second antenna switching capability, and the network-side device determines the number of SRS resource sets configured for the terminal based on the antenna switching capability, including:

[0286] When the terminal supports antenna switching transmission mode with 1 transmitting antenna and 2 receiving antennas and / or antenna switching transmission mode with 2 transmitting antennas and 4 receiving antennas, the terminal is configured with up to 2 semi-persistent SRS resource sets, up to 1 periodic SRS resource set, and up to 2 aperiodic SRS resource sets.

[0287] In this embodiment, when the terminal supports both the first antenna switching capability and the second antenna switching capability, the SRS resource set can be configured for the terminal according to the SRS resource configuration limit of the first antenna switching capability and the second antenna switching capability. This ensures that the network-side device and the terminal have the same understanding of the antenna switching capability reported by the terminal, preventing the number of SRS resource sets configured by the network-side device from exceeding the antenna switching capability that the terminal can support, and ensuring that the configured SRS resources can be sent and received normally.

[0288] In some embodiments, when the network-side device configures two semi-persistent SRS resource sets for the terminal, it configures one aperiodic SRS resource set or does not configure an aperiodic SRS resource set for the terminal; or

[0289] When the network-side device configures two aperiodic SRS resource sets for the terminal, it configures one semi-persistent SRS resource set or does not configure a semi-persistent SRS resource set for the terminal; or

[0290] When the network-side device configures two semi-persistent SRS resource sets and two aperiodic SRS resource sets for the terminal, a periodic SRS resource set is not configured for the terminal; or

[0291] When the network-side device configures two semi-persistent SRS resource sets and two aperiodic SRS resource sets for the terminal, it can configure up to five SRS resource sets for the terminal.

[0292] In a specific example, the network-side device supports configuring up to 4 SRS resource sets for the terminal. In addition to configuring up to 2 semi-persistent SRS resource sets and / or 2 non-periodic SRS resource sets for the terminal at the same time, when configuring multiple SRS resource sets for the terminal, the resource types of the configured SRS resource sets need to be different.

[0293] Alternatively, the number of semi-persistent SRS resource sets and aperiodic SRS resource sets cannot be configured to be 2 at the same time.

[0294] Alternatively, when the number of semi-persistent SRS resource sets and aperiodic SRS resource sets are both configured to be 2, the terminal does not expect the network-side device to configure a periodic SRS resource set.

[0295] In some embodiments, the number of semi-persistent SRS resource sets and aperiodic SRS resource sets cannot be configured to be two simultaneously. The SRS resource set configured by the network-side device for the terminal is selected from a first combination, which includes at least one of the following:

[0296] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0297] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0298] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 2 aperiodic SRS resource sets;

[0299] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 0 aperiodic SRS resource sets;

[0300] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 1 aperiodic SRS resource set;

[0301] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 2 aperiodic SRS resource sets;

[0302] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0303] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0304] One periodic SRS resource set, zero semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0305] One periodic SRS resource set, zero semi-persistent SRS resource sets, and one aperiodic SRS resource set;

[0306] One periodic SRS resource set, zero semi-persistent SRS resource sets, and two aperiodic SRS resource sets;

[0307] One periodic SRS resource set, one semi-persistent SRS resource set, and zero aperiodic SRS resource sets;

[0308] One periodic SRS resource set, one semi-persistent SRS resource set, and one non-periodic SRS resource set;

[0309] One periodic SRS resource set, one semi-persistent SRS resource set, and two aperiodic SRS resource sets;

[0310] One periodic SRS resource set, two semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0311] One periodic SRS resource set, two semi-persistent SRS resource sets, and one non-periodic SRS resource set.

[0312] In some embodiments, when the number of semi-persistent SRS resource sets and aperiodic SRS resource sets are both configured to be two, the terminal does not expect the network-side device to configure a periodic SRS resource set. The SRS resource set configured by the network-side device for the terminal is selected from a first combination, which includes at least one of the following:

[0313] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0314] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0315] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 2 aperiodic SRS resource sets;

[0316] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 0 aperiodic SRS resource sets;

[0317] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 1 aperiodic SRS resource set;

[0318] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 2 aperiodic SRS resource sets;

[0319] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0320] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0321] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 2 aperiodic SRS resource sets;

[0322] One periodic SRS resource set, zero semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0323] One periodic SRS resource set, zero semi-persistent SRS resource sets, and one aperiodic SRS resource set;

[0324] One periodic SRS resource set, zero semi-persistent SRS resource sets, and two aperiodic SRS resource sets;

[0325] One periodic SRS resource set, one semi-persistent SRS resource set, and zero aperiodic SRS resource sets;

[0326] One periodic SRS resource set, one semi-persistent SRS resource set, and one non-periodic SRS resource set;

[0327] One periodic SRS resource set, one semi-persistent SRS resource set, and two aperiodic SRS resource sets;

[0328] One periodic SRS resource set, two semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0329] One periodic SRS resource set, two semi-persistent SRS resource sets, and one aperiodic SRS resource set. In another specific example, the network-side device supports configuring up to five SRS resource sets for the terminal.

[0330] In addition to being able to configure up to two semi-persistent SRS resource sets and / or two aperiodic SRS resource sets for a terminal at the same time, when configuring multiple SRS resource sets for a terminal, the resource types of the configured SRS resource sets need to be different.

[0331] Alternatively, a maximum of 5 SRS resource sets can be configured for a terminal only when 2 semi-persistent SRS resource sets and 2 aperiodic SRS resource sets are configured for the terminal at the same time.

[0332] The SRS resource set configured by the network-side device for the terminal is selected from a first combination, which includes at least one of the following:

[0333] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0334] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0335] 0 periodic SRS resource sets, 0 semi-persistent SRS resource sets, and 2 aperiodic SRS resource sets;

[0336] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 0 aperiodic SRS resource sets;

[0337] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 1 aperiodic SRS resource set;

[0338] 0 periodic SRS resource sets, 1 semi-persistent SRS resource set, and 2 aperiodic SRS resource sets;

[0339] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 0 aperiodic SRS resource sets;

[0340] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 1 aperiodic SRS resource set;

[0341] 0 periodic SRS resource sets, 2 semi-persistent SRS resource sets, and 2 aperiodic SRS resource sets;

[0342] One periodic SRS resource set, zero semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0343] One periodic SRS resource set, zero semi-persistent SRS resource sets, and one aperiodic SRS resource set;

[0344] One periodic SRS resource set, zero semi-persistent SRS resource sets, and two aperiodic SRS resource sets;

[0345] One periodic SRS resource set, one semi-persistent SRS resource set, and zero aperiodic SRS resource sets;

[0346] One periodic SRS resource set, one semi-persistent SRS resource set, and one non-periodic SRS resource set;

[0347] One periodic SRS resource set, one semi-persistent SRS resource set, and two aperiodic SRS resource sets;

[0348] One periodic SRS resource set, two semi-persistent SRS resource sets, and zero aperiodic SRS resource sets;

[0349] One periodic SRS resource set, two semi-persistent SRS resource sets, and one non-periodic SRS resource set;

[0350] One periodic SRS resource set, two semi-persistent SRS resource sets, and two aperiodic SRS resource sets.

[0351] As can be seen from the above embodiments, the network-side device configures multiple SRS resource sets for the terminal, and the resource types of the multiple SRS resource sets are not completely the same.

[0352] In the above embodiments, when configuring SRS resource sets for terminals, the network-side device needs to meet the quantity limit of the first combination on the SRS resource sets.

[0353] This application also provides an SRS resource configuration method, such as... Figure 3 As shown, it includes:

[0354] Step 201: The terminal reports its supported antenna switching capabilities for SRS to the network-side device;

[0355] Step 202: The terminal receives SRS configuration information from the network-side device, wherein the SRS configuration information indicates the number of SRS resource sets configured by the network-side device for the terminal based on the antenna switching capability.

[0356] In this embodiment, the network-side device determines the number of SRS resource sets configured by the terminal based on the antenna switching capabilities reported by the terminal. This ensures that the network-side device and the terminal have the same understanding of the antenna switching capabilities reported by the terminal, preventing the number of SRS resource sets configured by the network-side device from exceeding the antenna switching capabilities that the terminal can support, and ensuring that the configured SRS resources can be sent and received normally.

[0357] In some embodiments, the antenna switching capability includes a first antenna switching capability and a second antenna switching capability, wherein the first antenna switching capability supports up to N periodic SRS resource sets and up to M semi-persistent SRS resource sets, and the second antenna switching capability supports up to K aperiodic SRS resource sets.

[0358] When the terminal reports support for the first antenna switching capability, the number of periodic SRS resource sets configured for the terminal is determined by the maximum number N of periodic SRS resource sets supported by the first antenna switching capability, where N is an integer.

[0359] When the terminal reports support for the first antenna switching capability, the number of semi-persistent SRS resource sets configured for the terminal is determined by the maximum number M of semi-persistent SRS resource sets supported by the first antenna switching capability, where M is an integer.

[0360] When the terminal reports support for the second antenna switching capability, the number of aperiodic SRS resource sets configured for the terminal is determined by the maximum number K of aperiodic SRS resource sets supported by the second antenna switching capability, where K is an integer.

[0361] In this way, regardless of whether the terminal supports the first antenna switching capability, the second antenna switching capability, or both, the network-side device and the terminal can have the same understanding of the antenna switching capability reported by the terminal. This prevents the number of SRS resource sets configured by the network-side device from exceeding the antenna switching capability that the terminal can support, and ensures that the configured SRS resources can be sent and received normally.
