Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular to an SRS sending method, device, and storage medium for antenna switching configuration. Background Art

[0002] To support various terminals with different transceiver capabilities and effectively acquire downlink information through the channel, the communication system sets different antenna switching configurations for the terminals. Different antenna switching configurations correspond to different Sounding Reference Signal (SRS) resources.

[0003] In the related art, in order to adapt to business changes, dynamic switching of antenna switching configurations is introduced. However, the SRS resources corresponding to different antenna switching configurations can be non-periodic SRS (A-SRS), semi-continuous SRS (SP-SRS), or periodic SRS (P-SRS). When the SRS resources corresponding to the antenna slicing configuration are dynamically switched for a certain antenna switching configuration, it may happen that the SRS resources cannot be updated synchronously. For example, if A-SRS or SP-SRS is dynamically switched through network configuration and obtains an antenna switching configuration update, the terminal may still have P / SP-SRS or A-SRS / P-SRS still in the previous antenna switching configuration. The SRS resources cannot be updated synchronously, which may result in, for example, the switch of the transmit link or receive link (Tx / Rx RF chain) cannot be actually turned off, and therefore cannot completely solve similar terminal power saving needs.

This multi-transmission, multi-reception approach, achieved by multiple antennas, can exponentially increase system channel capacity without increasing spectrum resources or antenna transmit power, while also improving data throughput and signal-to-noise ratio, thereby enhancing system performance and communication quality.

[0102] In order to support various terminal transceiver capabilities to effectively obtain downlink information through the channel, different antenna switching configurations are set for the terminals in the communication system. The antenna switching capability of the terminal defined by R15 / 16 can be divided into the number of receiving antennas and the number of transmitting antennas being the same (i.e., T=R), and the number of receiving antennas being more than the number of transmitting antennas (i.e., R>T). In related technologies, the current protocol supports the case of T=R, and the terminal antenna switching capabilities mainly include one transmit and one receive (1T1R), two transmit and two receive (2T2R), and four transmit and four receive (4T4R). In the case of R>T, that is, there are several main cases where there are more receive antennas than transmit antennas: one transmit and two receive (1T2R), one transmit and four receive (1T4R), and two transmit and four receive (2T4R).

[0103] Among them, the antenna switching capabilities supported by the terminal in R15 are: 1T2R, 1T4R, 2T4R, 1T4R-2T4R, 1T1R, 2T2R, and 4T4R.

[0104] The antenna switching capabilities supported by terminals in R16 are: 1T1R-1T2R, 1T1R-1T2R-1T4R, 1T1R-1T2R-2T2R-2T4R, 1T1R-1T2R-2T2R-1T4R-2T4R, 1T1R-2T2R, 1T1R-2T2R-4T4R.

[0105] Currently, in the R17 research, considering the need to further increase the number of antennas in terminals, the number of antennas will be further increased to a maximum of 6 or 8. The currently defined typical antenna configurations are {1T6R, 1T8R, 2T6R, 2T8R, [4T6R], 4T8R}, as shown in Table 1 below:

[0106] Table 1: SRS antenna switching combinations up to 8 antennas

[0107]

[0108]

[0109] In related technologies, a sounding reference signal (SRS) is configured for antenna switching configuration. Different antenna switching configurations correspond to different SRSs. The SRSs for antenna switching configuration supported in the current protocol are as follows:

[0110] (1) For terminals with the same number of transmit and receive antennas (T = R), the network device can configure a maximum of two SRS resource sets. In each set, there is only one SRS resource with the same number of ports as the terminal's transmit antennas. One of the two SRS resource sets can be configured as periodic, and the other can be configured as aperiodic.

[0111] (2) For a terminal with one transmit and two receive (1T2R) capability, the network device can be configured with a maximum of two SRS resource sets. In one set, there are two SRS resources, and each SRS resource has only one port.

[0112] (3) For a terminal with two-transmit and four-receive (2T4R) capability, the network device can be configured with a maximum of two SRS resource sets, with two SRS resources in one set and two ports in each SRS resource.

[0113] (4) For terminals with 1T4R (one transmit, four receive) capabilities, network equipment configuration of SRS resources requires special consideration. For periodic or semi-persistent SRS resources, only one resource set can be configured, with four SRS resources each having one port. For aperiodic SRS resources, a maximum of two SRS resource sets can be configured, with a total of four SRS resources in the two SRS resource sets. These four resources are transmitted in two slots and from different physical antennas. Two resource sets can each be configured with two resources, or one set with one resource and the other with three resources, with each resource having only one port.

[0114] In the 5G NR system, the triggering of SRS resources may include periodic / semi-persistent / aperiodic SRS resource configuration triggering mechanisms.

[0115] All parameters for the periodic SRS (P-SRS) are configured by higher-layer signaling. After this configuration, the terminal periodically transmits according to the configured parameters. All parameters for the semi-persistent SRS (SP-SRS) are also configured by higher-layer signaling. Unlike the periodic sounding reference signal (SRS), although the corresponding parameters have been configured, the terminal cannot transmit the SRS until it receives an activation command. Once activated, the terminal begins transmitting the SRS until it receives a deactivation command from the network device, at which point it ceases. The activation and deactivation commands for the SP-SRS are sent by the MAC layer, namely, MAC CE commands.

[0116] The aperiodic SRS resource (AP-SRS) is triggered by the SRS request in the downlink control signaling (Downlink Control Information, DCI). Table 2 shows the specific triggering signaling.

[0117] Table 2

[0118]

[0119] In related technologies, uplink SRS can be P-SRS, SP-SRS or AP-SRS. Narrowband or broadband, single port or multi-port. Uplink SRS parameters are configured by the network equipment to the terminal and include the number of ports, frequency domain resource location, time domain resource location, sequence, sequence cycle offset, etc. In the 5G NR system, SRS is mapped on up to six symbols in an uplink time slot, such as Figure 2 As shown, the SRS mapping area within the time slot is shown.

[0120] The network device can configure multiple uplink SRS sets for the terminal. A resource set contains one or more SRS resources. An SRS resource can be on N consecutive OFDM symbols, where N can occupy 1, 2, or 4 symbols.

[0121] In Release 15 / 16 NR systems, base stations and other network devices use channel reciprocity to obtain downlink channel information, improving downlink data transmission performance. To ensure that gNBs can effectively obtain downlink information through channel reciprocity despite the various terminal transceiver capabilities, the NR system specifically designs the SRS reference signal.

[0122] Furthermore, in order to adapt to the current business or scenario, the terminal may need to change the antenna configuration, for example, from 2T4R to 1T4R or 2T2R, or from 2T2R to 4T4R. In this case, the antenna switching configuration needs to be switched.

[0123] In the related art, the switching of the antenna switching configuration of the terminal supports the switching of the antenna switching configuration for a certain SRS type. For example, a 4T8R terminal can achieve similar power saving requirements by turning off the transmit link (Tx chain), and can switch to 2T8R or 1T8R. However, when the SRS resources corresponding to the antenna slicing configuration are dynamically switched for a certain antenna switching configuration, it may happen that the SRS resources cannot be updated synchronously. For example, if A-SRS or SP-SRS is dynamically switched through network configuration and obtains an antenna switching configuration update, the terminal may still have P / SP-SRS or A-SRS / P-SRS still in the previous antenna switching configuration. The SRS resources cannot be updated synchronously, which may result in, for example, the Tx / Rx RF chain switch being unable to be actually turned off, and therefore cannot completely solve similar terminal power saving needs.

[0124] An embodiment of the present disclosure provides an SRS transmission method for antenna switching configuration, wherein the SRS type configured by a terminal for the antenna switching configuration includes at least two different SRS types. If an SRS type SRS resource of the at least two different SRS types has an antenna switching configuration change, the antenna switching configuration corresponding to all SRS type SRS resources of the at least two different SRS types is synchronously updated.

[0125] In the embodiment of the present disclosure, for ease of description, the SRS type corresponding to the SRS resource with a changed antenna switching configuration is referred to as the first SRS type. The other SRS type different from the first SRS type among the at least two different SRS types configured by the terminal is referred to as the second SRS type.

[0126] Figure 3 FIG. 1 is a flow chart showing a method for transmitting an SRS for antenna switching configuration according to an exemplary embodiment. Figure 3 As shown, the SRS sending method for antenna switching configuration is used in a terminal and includes the following steps.

[0127] In step S11, an SRS type configured by the terminal for antenna switching configuration is determined, where the SRS type includes at least two different SRS types.

[0128] In step S12, it is determined that the antenna switching configuration corresponding to the first SRS type SRS resource is changed to the target antenna switching configuration, and the antenna switching configuration corresponding to the second SRS type SRS resource is synchronously updated to the target antenna switching configuration.

[0129] The second SRS type is all other SRS types that are different from the first SRS type among the at least two different SRS types.

[0130] In step S13, an SRS resource corresponding to the target antenna switching configuration is selected as the target SRS resource.

[0131] In step S14, the first SRS type SRS resource and the second SRS type SRS resource are sent according to the antenna or antenna port corresponding to the target SRS resource.

[0132] In the embodiment of the present disclosure, the SRS type configured by the terminal for antenna switching configuration includes at least two types of SRS among P-SRS resources, SP-SRS resources and AP-SRS resources.

[0133] The first SRS type SRS resource and the second SRS type SRS resource are SRS resources of different SRS types.

[0134] In one embodiment, the first SRS type SRS resource is an AP-SRS resource, and the second SRS type SRS resource is a P-SRS resource or an SP-SRS resource. Alternatively, the SRS type SRS resource is an AP-SRS resource or an SP-SRS resource, and the second SRS type SRS resource is a P-SRS resource.

[0135] In another embodiment, the first SRS type SRS resource is a P-SRS resource, and the second SRS type SRS resource is an AP-SRS resource or an SP-SRS resource. Alternatively, the SRS type SRS resource is a P-SRS resource or an SP-SRS resource, and the second SRS type SRS resource is an AP-SRS resource.

[0136] In the embodiment of the present disclosure, the antenna switching configuration corresponding to the first SRS type SRS resource is changed to the target antenna switching configuration, and the antenna switching configuration corresponding to the second SRS type SRS resource is synchronously updated to the target antenna switching configuration.

[0137] In one example, the first SRS type SRS resource is AP-SRS, and the second SRS type SRS resource is P-SRS / SP-SRS. When the antenna switching configuration corresponding to AP-SRS changes, the antenna switching configuration of P-SRS / SP-SRS is updated synchronously, and the SRS resource in the SRS resource configuration is selected accordingly, and the same Tx / Rx antenna or Tx / Rx antenna port as AP-SRS is used. Or the first SRS type SRS resource is SP-SRS / AP-SRS, and the second SRS type SRS resource is P-SRS. When the antenna switching configuration corresponding to SP-SRS / AP-SRS changes, the antenna switching configuration of P-SRS is updated synchronously, and the SRS resource in the SRS resource configuration is selected accordingly, and the same Tx / Rx antenna or Tx / Rx antenna port as SP-SRS / AP-SRS is used.

[0138] In another example, the first SRS type SRS resource is P-SRS, and the second SRS type SRS resource is AP-SRS / SP-SRS. When the antenna switching configuration corresponding to P-SRS changes, the antenna switching configuration of AP-SRS / SP-SRS is updated synchronously, and the SRS resources in the SRS resource configuration are selected accordingly to ensure that the same Tx / Rx antenna or Tx / Rx antenna port as P-SRS is used. Or the first SRS type SRS resource is P-SRS / SP-SRS, and the second SRS type SRS resource is AP-SRS. When the antenna switching configuration corresponding to P-SRS / SP-SRS changes, the antenna switching configuration of AP-SRS is updated synchronously, and the SRS resources in the SRS resource configuration are selected accordingly to ensure that the same Tx / Rx antenna or Tx / Rx antenna port as P-SRS / SP-SRS is used.

[0139] In the embodiment of the present disclosure, the terminal synchronously updates the antenna switching configurations corresponding to different SRS types. On the one hand, it can be that when it is determined that the network device allows the synchronous updating of the antenna switching configurations corresponding to at least two different SRS types, the antenna switching configurations corresponding to at least two different SRS types are synchronously updated to the target antenna switching configuration. Among them, the network can indicate to the terminal through signaling that it allows synchronous adaptive updating / synchronization of all configuration types to be sent using the same antenna switching configuration. For the convenience of description, the indication information indicating that the antenna switching configurations corresponding to at least two different SRS types are allowed to be synchronously updated to the target antenna switching configuration is referred to as the first indication information. The network device sends the first indication information to the terminal, indicating that the antenna switching configurations corresponding to at least two different SRS types are allowed to be synchronously updated to the target antenna switching configuration. The terminal receives the first indication information and synchronously updates the antenna switching configurations corresponding to at least two different SRS types to the target antenna switching configuration.

[0140] Figure 4 FIG1 is a flow chart showing a method for transmitting an SRS in an antenna switching configuration according to an exemplary embodiment. The method for transmitting an SRS in an antenna switching configuration can be performed alone or in combination with other embodiments. Figure 4 As shown, the SRS sending method for antenna switching configuration is used in a terminal and includes the following steps.

[0141] In step S21, first indication information is received, where the first indication information indicates that antenna switching configurations corresponding to at least two different SRS types are allowed to be synchronously updated as target antenna switching configurations.

[0142] In the embodiment of the present disclosure, the first indication information may include at least one of the following:

[0143] Radio Resource Control Information (RRC), Media Access Control-Control Element (MAC CE), Downlink Control Information (DCI), and Grant Controller-DCI (GC-DCI).

[0144] In the embodiment of the present disclosure, the terminal synchronously updates the antenna switching configuration corresponding to different SRS types. On the other hand, the terminal can adaptively select corresponding SRS resources for corresponding type of SRS transmission within the SRS resource configuration range of different SRS types according to a predefined method and network agreement.

[0145] Figure 5 FIG1 is a flow chart showing a method for transmitting an SRS in an antenna switching configuration according to an exemplary embodiment. The method for transmitting an SRS in an antenna switching configuration can be performed alone or in combination with other embodiments. Figure 5 As shown, the SRS sending method for antenna switching configuration is used in a terminal and includes the following steps.

[0146] In step S31, it is determined that a pre-agreed condition is satisfied, where the pre-agreed condition is a condition that antenna switching configurations corresponding to at least two different SRS types are synchronously updated to be a target antenna switching configuration.

[0147] In step S32, second indication information is reported, where the second indication information indicates that the antenna switching configuration has changed.

[0148] In the embodiments of the present disclosure, the pre-agreed condition can be pre-agreed based on terminal power saving demand, terminal antenna multiplexing condition change, etc. For example, the terminal determines the pre-agreed condition meeting the power saving demand based on the power saving demand, changes the antenna switching configuration, reports the second indication information, and indicates that the antenna switching configuration is changed based on the power saving demand. The network device receives the second indication information, determines that the terminal changes the antenna switching configuration based on the power saving demand, and further synchronously understands the change of the antenna switching configuration.

[0149] In the embodiments of the present disclosure, the second indication information can include at least one of RRC, MAC CE, DCI, and GC-DCI.

[0150] In the embodiments of the present disclosure, the terminal synchronously updates the antenna switching configuration of the SRS resources of the plurality of different SRS types to the target antenna switching configuration, and selects the SRS resource meeting the target antenna switching configuration as the target SRS resource. Among them, for each SRS type in the at least two different SRS types, all or part of the SRS resources meeting the target antenna switching configuration are reselected in the SRS resource configuration corresponding to the SRS type as the target SRS resource.

[0151] In the embodiments of the present disclosure, the first SRS type SRS resource and the second SRS type SRS resource are transmitted according to the antenna or antenna port corresponding to the target SRS resource.

[0152] In the embodiments of the present disclosure, the terminal transmits the first SRS type SRS resource and the second SRS type SRS resource according to the antenna or antenna port corresponding to the target SRS resource, which can transmit the first SRS type SRS resource and the second SRS type SRS resource in different ways based on different update modes.

[0153] In an implementation mode, the terminal synchronously updates the antenna switching configuration of the SRS resources of the plurality of different SRS types to the target antenna switching configuration based on the first indication information, and transmits the first SRS type SRS resource and the second SRS type SRS resource, which can transmit the to-be-transmitted SRS resource based on the change time of the changed antenna switching configuration and the SRS type of the to-be-transmitted SRS resource.

[0154] Figure 6 FIG. 1 is a flowchart of a SRS transmission method for antenna switching configuration according to an example embodiment, which can be executed alone or in combination with other embodiments. As shown in FIG. 1, the SRS transmission method for antenna switching configuration is used in a terminal, which includes the following steps. Figure 6

[0155] ​In step S41, it is determined whether the first indication information is received, and the change time of the antenna switching configuration change is determined.

[0156] In step S42, based on the change time of the antenna switching configuration and the SRS type of the SRS resource to be sent, the SRS resource to be sent includes a first SRS type SRS resource and a second SRS type SRS resource.

[0157] In one implementation, the SRS type of the SRS resource to be sent is a P-SRS resource or an AP-SRS resource, and the SRS resource to be sent is sent at a change time when the antenna switching configuration changes.

[0158] In another implementation manner, the SRS type of the SRS resource to be sent is an SP-SRS resource, and the SRS resource to be sent is sent in at least one of the following ways:

[0159] A: The SRS resource to be sent starts at the time when the antenna switching configuration changes. This can also be understood as being immediately applied to the start of SRS transmission when the antenna configuration changes.

[0160] B: If the antenna switching configuration is changed during an SRS sounding transmission cycle, the SRS resources to be transmitted are transmitted at the start time of the next sounding transmission cycle after the SRS resource set corresponding to the sounding transmission cycle completes a complete sounding. This can also be understood as applying to SRS transmission after an SRS resource set completes sounding.

[0161] C: The SRS resources to be sent are uniformly sent in the next scheduling period after the SRS resource set scheduling period corresponding to the change time of the antenna switching configuration change. This can also be understood as aligning the change to the next P-SRS transmission time.

[0162] In another embodiment, the terminal reports the second indication information based on pre-agreed conditions, synchronously updates the antenna switching configurations corresponding to at least two different SRS types to the target antenna switching configuration, and sends the SRS resources to be sent based on the reporting time of the second indication information and the SRS type of the SRS resources to be sent.

[0163] Figure 7 FIG1 is a flow chart showing a method for transmitting an SRS in an antenna switching configuration according to an exemplary embodiment. The method for transmitting an SRS in an antenna switching configuration can be performed alone or in combination with other embodiments. Figure 7 As shown, the SRS sending method for antenna switching configuration is used in a terminal and includes the following steps.

[0164] In step S51, a reporting time for reporting the second indication information is determined.

[0165] In step S52, based on the reporting time of the second indication information and the SRS type of the SRS resource to be sent, the SRS resource to be sent is sent, where the SRS resource to be sent includes a first SRS type SRS resource and a second SRS type SRS resource.

[0166] In one implementation, the SRS type of the SRS resource to be sent is a P-SRS resource or an AP-SRS resource, and the SRS resource to be sent is sent at the reporting time of the second indication information.

[0167] In one implementation, the SRS type of the SRS resource to be sent is an SP-SRS resource, and the SRS resource to be sent is sent in at least one of the following ways:

[0168] A: Send the SRS resources to be sent at the reporting time of the second indication information. This can also be understood as being immediately applied to SRS transmission starting from the reporting time of the second indication information.

[0169] B: Send the SRS resources to be sent at the start time of the next detection cycle after the SRS resource set corresponding to the reporting time of the second indication information completes detection. This can also be understood as being applied to SRS transmission after an SRS resource set is completely sounding.

[0170] C: The SRS resources to be sent are uniformly sent in the next scheduling period after the SRS resource set scheduling period corresponding to the reporting time of the second indication information. This can also be understood as being aligned to the next P-SRS sending time.

[0171] The above-mentioned SRS transmission method for antenna switching configuration applied to the terminal provided in the embodiment of the present disclosure can synchronize different types of SRS under certain scenarios or requirements, ensuring that the terminal can adaptively select the SRS resources actually sent when sending SRS, and use the same Tx / Rx chain to actually meet terminal requirements such as power saving.

[0172] Based on the same concept, an embodiment of the present disclosure further provides an SRS transmission method for antenna switching configuration, which is executed by a network device.

[0173] Figure 8 FIG1 is a flow chart showing a method for transmitting an SRS in an antenna switching configuration according to an exemplary embodiment. The method for transmitting an SRS in an antenna switching configuration can be performed alone or in combination with other embodiments. Figure 8 As shown, the SRS sending method for antenna switching configuration is used in a network device and includes the following steps.

[0174] In step S61, the first SRS type SRS resource and the second SRS type SRS resource are received on the antenna or the antenna port corresponding to the target SRS resource.

[0175] The antenna switching configuration corresponding to the second SRS type SRS resource is a target antenna switching configuration that is changed from the antenna switching configuration corresponding to the first SRS type SRS resource, the second SRS type is all other SRS types different from the first SRS type among at least two different SRS types, and the target SRS resource conforms to the SRS resource corresponding to the target antenna switching configuration.

[0176] Figure 9 FIG. 8 is a flowchart illustrating a method for transmitting SRS for antenna switching configuration according to an example embodiment. The method for transmitting SRS for antenna switching configuration can be performed alone or in combination with other embodiments. As shown in FIG. 8, the method for transmitting SRS for antenna switching configuration is used in a network device, and includes the following steps. Figure 9

[0177] In step S71, first indication information is transmitted, and the first indication information indicates that at least two different SRS types corresponding to the antenna switching configuration are allowed to be synchronously updated to a target antenna switching configuration.

[0178] In the embodiments of the present disclosure, the first indication information can include at least one of RRC, MAC CE, DCI, and GC-DCI.

[0179] In an implementation, the network device receives the to-be-received SRS resource based on a change time at which the antenna switching configuration changes and an SRS type of the to-be-received SRS resource, and the to-be-received SRS resource includes a first SRS type SRS resource and a second SRS type SRS resource.

[0180] On one hand, the SRS type of the to-be-received SRS resource is a P-SRS resource or an AP-SRS resource, and the to-be-received SRS resource is received at the change time. On the other hand, the SRS type of the to-be-received SRS resource is a SP-SRS resource, and the to-be-received SRS resource is received in at least one of the following ways:

[0181] A: The to-be-received SRS resource is received starting at the change time.

[0182] B: In response to the change time being in a sounding transmission period in which SRS has already started, the to-be-received SRS resource is received at the start time of the next sounding transmission period after a complete sounding of a SRS resource set corresponding to the sounding transmission period.

[0183] ​C: receiving the SRS resources to be received in a unified manner in the next scheduling period after the SRS resource set scheduling period corresponding to the change time.

Figure 10 As shown, the SRS sending method for antenna switching configuration is used in a network device, including the following steps:

[0187] In the embodiment of the present disclosure, the second indication information may include at least one of RRC, MAC CE, DCI, and GC-DCI.

[0188] In one embodiment, the network device determines a reporting time for receiving the second indication information and receives the SRS resources to be received based on the reporting time of the second indication information and the SRS type of the SRS resources to be received, where the SRS resources to be received include first SRS type SRS resources and second SRS type SRS resources.
