Fig. 1 is a schematic flow chart diagram illustrating a method of port switching according to an embodiment of the present disclosure. The port switching method shown in the embodiment may be executed by a terminal, where the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other communication devices. The terminal may communicate with network devices including, but not limited to, network devices in 4G, 5G, 6G, etc., communication systems, e.g., base stations, core networks, etc.

As shown in fig. 1, the port switching method may include the steps of:

in step S101, determining a target configuration from a plurality of sounding reference signal SRS configurations for port switching according to the indication information sent by the network device;

In step S102, port switching is performed according to the target configuration.

Ports in all embodiments of the present disclosure may be referred to as antennas or logical ports.

In one embodiment, the network device may instruct the terminal to switch SRS configuration through radio resource control (Radio Resource Control, RRC) signaling, or in configuring a BandWidth Part (BWP) of the terminal to switch SRS configuration, but these manners for instructing the terminal to switch SRS configuration have low flexibility and are difficult to adapt to the needs of the terminal.

The SRS configuration includes information about resources used for transmitting the SRS, such as time domain resources used for transmitting the SRS, frequency domain resources, ports used for transmitting the SRS, and the like.

For example, a plurality of SIM (Subscriber Identity Module, subscriber identity) cards may be provided in a terminal that may support dual card dual pass, dual receive dual card dual standby, etc. modes. Taking the SIM card #1 and the SIM card #2 of the plurality of SIM cards as an example, for example, when the terminal uses the SIM card #1 to communicate, the terminal sends the SRS through the port #1, and in this process, the SIM card #2 is started and occupies the port #1, so that the terminal cannot send the SRS smoothly using the port # 1.

In this case, in order to switch from port #1 to port #2 for transmitting SRS, the terminal needs to wait for RRC signaling or BWP switch indication transmitted by the network device, but neither RRC signaling nor BWP switch indication can realize dynamic indication, for example, RRC signaling is generally transmitted during RRC connection establishment or disconnection, so it is difficult to transmit to the terminal in time, change configuration of terminal for transmitting SRS, and affect transmission effect and timeliness of SRS.

It should be noted that, the reason why the terminal needs to switch the port for transmitting the SRS includes, but is not limited to, the above-mentioned effect of using the SIM card, for example, the terminal itself needs to adjust the capability of switching the sounding reference signal transmission port SRS-txport switch, which also generates the need to switch the port for transmitting the SRS.

For example, in the case where the SIM card #2 in the foregoing embodiment is started and occupies the port #1, the network device may send an SRS configuration, where the SRS configuration may include a port corresponding to a resource for sending the SRS, for example, the corresponding port is port #2, and then, according to the received configuration, the terminal may timely change to send the SRS using port #2, so as to ensure timely sending of the SRS.

In one embodiment, the plurality of SRS configurations may be pre-indicated to the terminal by the network device (e.g., configured to the terminal through RRC signaling), or may be protocol-agreed. The following embodiments mainly exemplify the case where a plurality of SRS configurations are indicated to a terminal in advance as network devices.

In one embodiment, the indication information includes, but is not limited to, downlink control information (Downlink Control Information, DCI), medium access control layer control element (Media Access Control Control Element, MAC CE), etc.

In one embodiment, the SRS configuration includes at least one of:

a set of resources for transmitting SRS-ResourceSet;

the Resource SRS-Resource contained in the set;

the port antenna PortForSRS-resource set corresponding to the set;

the port antenna PortForSRS corresponding to the resource;

the type of the resource is SRS-ResourceType (including but not limited to periodic, aperiodic, semi-persistent, etc. types).

In one embodiment, the network device may pre-configure the terminal with a plurality of sets of resources for transmitting SRS, which may include at least one resource (e.g., time domain resource and/or frequency domain resource) for transmitting SRS. And the network equipment can indicate one set in the sets through the indication information, the terminal can determine the set indicated by the network equipment according to the indication information, then switch to a port corresponding to the set, and send SRS by using the resources in the set.

The network device may configure a plurality of resources in the set for the terminal in advance, and further may indicate one resource in the plurality of resources through the indication information, and the terminal may determine the resource indicated by the network device according to the indication information, and further switch to a port corresponding to the resource, and send the SRS using the resource indicated by the network device.

The network device may configure a plurality of ports corresponding to the set for the terminal in advance, and further may indicate one port in the plurality of ports through the indication information, and the terminal may determine the port indicated by the network device according to the indication information, and further switch to the port indicated by the network device to send the SRS.

The network device may configure a plurality of ports corresponding to the resources for the terminal in advance, and further may indicate one port in the plurality of ports through the indication information, and the terminal may determine the port indicated by the network device according to the indication information, and further switch to the port indicated by the network device to send the SRS.

The manner in which the network device transmits the indication information to the terminal is exemplarily described below by way of two embodiments, and it should be understood that the manner in which the network device transmits the indication information to the terminal is not limited to the following embodiments, and may be selected as desired.

In one embodiment, the determining, according to the indication information sent by the network device, a target configuration among the plurality of SRS configurations includes: receiving a configuration identifier sent by the network equipment; and determining the SRS configuration corresponding to the configuration identifier as the target configuration in a plurality of SRS configurations.

The network device may determine a target configuration that needs to be indicated to the terminal in the plurality of SRS configurations, further determine a configuration identifier corresponding to the target configuration, and send the configuration identifier to the terminal, where the terminal may determine the target configuration in the plurality of SRS configurations according to the configuration identifier.

For example, the SRS configuration includes a set of resources for transmitting SRS, the network device may determine a set identifier of the set to be indicated to the terminal, and transmit the set identifier to the terminal, and the terminal may determine a corresponding set according to the received set identifier, and switch to a port corresponding to the set to transmit SRS.

In one embodiment, the determining, according to the indication information sent by the network device, a target configuration among the plurality of SRS configurations includes: and receiving an activation instruction sent by the network equipment, and determining that the SRS configuration activated by the activation instruction is the target configuration in a plurality of SRS configurations.

The network device may send an activation indication to the terminal or may send a deactivation indication to the terminal. For example, the configuration identifier of the target configuration may be carried in the activation instruction, and the terminal may activate the target configuration according to the configuration identifier carried in the activation instruction, and further perform port switching according to the target configuration. The network device may then deactivate the previously activated target configuration by sending a deactivation indication to the terminal, thereby controlling the terminal to stop port switching according to the target configuration.

Fig. 2 is a schematic flow chart diagram illustrating another port switching method according to an embodiment of the present disclosure. As shown in fig. 2, the method further includes:

in step S201, capability information of the sounding reference signal transmission port switch srs-txport switch is transmitted to the network device.

In one embodiment, the capability information of srs-txport switch may include the number or combination of number of receive antennas (r) and transmit antennas (t) supported by the terminal, e.g., t1r2 indicates that the terminal supports 1 transmit antenna 2 receive antennas, e.g., t1r4-t2r4 indicates that the terminal supports 1 transmit antenna 4 receive antennas, as well as 2 transmit antennas 4 receive antennas.

Wherein the number or combination of the number of the receiving antennas (r) and the transmitting antennas (t) supported by the terminal comprises at least one of the following: t1r2, t1r4, t2r2, t4r4, t1r4-t2r4, t1r1-t1r2-t1r4, t1r1-t1r2-t2r2-t2r4, t1r1-t2r2-t4r4, t1r1-t1r2-t2r2-t1r4-t2r4.

It can be seen that as the capabilities of the srs-txport switch of the terminal change, the supporting situation of the terminal for the receiving antenna and the transmitting antenna also changes, so after determining the current srs-txport switch capabilities, the terminal can report srs-txport switch capability information to the network device.

The network device may select an appropriate SRS configuration for the terminal as a target configuration indication to the terminal according to the current SRS-txport switch capability of the terminal. For example, the network device determines that port #1 of the terminal for transmitting SRS is occupied, but port #2 is unoccupied according to the current SRS-txport switch capability of the terminal, and then by indicating the target configuration corresponding to port #2 to the terminal, the terminal is switched to transmit SRS using port # 2.

Fig. 3 is a schematic flow chart diagram illustrating yet another port switching method according to an embodiment of the present disclosure. As shown in fig. 3, the method further includes:

in step S301, auxiliary information is sent to the network device, where the auxiliary information is used to indicate an SRS configuration desired by the terminal.

In one embodiment, the terminal may determine an SRS configuration expected by the terminal, generate auxiliary information according to the SRS configuration, and report the auxiliary information to the terminal, and indicate the SRS configuration expected by the terminal to the network device through the auxiliary information, where the network device may determine that the SRS configuration expected by the terminal is indicated as a target configuration to the terminal, so that the terminal can smoothly send the SRS according to the SRS configuration indicated by the network device.

In addition, the terminal may further indicate the priority of the SRS configuration desired by the terminal through the auxiliary information, so that the network device may indicate the target configuration to the terminal according to the priority, for example, the network device may determine whether the SRS configuration desired by the terminal is available according to the priority from high to low, and select, as the target configuration indication, the SRS configuration with the highest priority from the available SRS configurations.

For example, the terminal-desired SRS configuration includes 2 desired sets of desired resources for transmitting SRS, respectively, preferred-SRS-resource set #1 and preferred-SRS-resource set #2, wherein the priority of preferred-SRS-resource set #1 is relatively high and the priority of preferred-SRS-resource set #2 is relatively low. The network device may first determine whether the preferred-SRS-resource set #1 and the preferred-SRS-resource set #2 are available, and if they are both available, may instruct the preferred-SRS-resource set #1 as a target configuration to the terminal; if only preferred-SRS-ResourceSet #2 is available, then preferred-SRS-ResourceSet #2 may be indicated to the terminal as the target configuration.

In one embodiment, the desired SRS configuration includes at least one of:

a desired configuration among a plurality of the SRS configurations;

A desired set of desired resources for transmitting SRS;

a desired resource contained by the desired set;

ports corresponding to the expected set;

ports corresponding to the expected resources;

the type of the desired resource.

In one embodiment, the network device may pre-configure the terminal with a plurality of sets of resources for transmitting SRS, which may include at least one resource (e.g., time domain resource and/or frequency domain resource) for transmitting SRS. The terminal may inform the network device of a desired configuration among the plurality of SRS configurations through the assistance information.

The network device may configure a plurality of resources in the set for the terminal in advance, and the terminal may inform the network device of a desired resource among the plurality of resources through the auxiliary information.

The network device may configure a plurality of ports corresponding to the set in advance for the terminal, or may configure a plurality of ports corresponding to the resource, where the terminal may inform the network device of a desired port among the plurality of ports through the auxiliary information.

It should be noted that, based on the above embodiment, the terminal may send the capability information of srs-txport switch to the network device, or may send the auxiliary information to the network device, where the network device may determine, according to the capability information and/or the auxiliary information of srs-txport switch, the target configuration to be indicated to the terminal, or may determine, according to the actual situation of the network device, the target configuration to be indicated to the terminal.

Fig. 4 is a schematic diagram illustrating interaction of a terminal with a network device according to an embodiment of the present disclosure. As shown in fig. 4:

the terminal sends srs-TxPortswitch Capability information to the network device, for example, the Capability information is carried in user equipment Capability information (UE Capability) and sent to the network device;

the network equipment sends RRC signaling, such as RRC reconfiguration message, to the terminal, wherein the RRC signaling carries a plurality of SRS configurations;

the terminal sends control information to the network equipment, wherein the control information can carry the auxiliary information so as to indicate the SRS configuration expected by the terminal;

the network device may determine the target configuration indication to the terminal according to SRS-txpoint switch capability of the terminal and/or the expected SRS configuration, or may determine the target configuration indication to the terminal by itself based on the actual situation, and the specific indication manner may refer to the foregoing embodiment and will not be described herein.

After SRS-txpoint switch capability and/or expected SRS configuration of the terminal are changed, the terminal can send the changed SRS-txpoint switch capability and/or expected SRS configuration to the network device;

the network equipment can redetermine the target configuration indication to the terminal according to the changed SRS-TxPortswitch capability and/or the expected SRS configuration, so that the target configuration indicated to the terminal is adapted to the current situation of the terminal, and the terminal can be ensured to smoothly send the SRS according to the target configuration; of course, the target configuration indication may be redetermined to the terminal according to the actual situation of the network device.

The port switching indication method shown in the embodiment may be executed by a network device, where the network device may communicate with a terminal, where the network device includes, but is not limited to, a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station, and the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, and a communication apparatus such as an internet of things device.

in step S201, indication information is sent to a terminal, where the indication information is used to indicate a target configuration in a plurality of sounding reference signal SRS configurations for port switching, so that the terminal performs port switching according to the target configuration.

In one embodiment, the network device may instruct the terminal to switch SRS configuration through radio resource control RRC signaling, or switch the bandwidth portion BWP at the configured terminal, but these manners of instructing the terminal to switch SRS configuration have low flexibility, and are difficult to adapt to the needs of the terminal.

For example, a plurality of SIM cards can be arranged in the terminal, and the terminal can support modes of double-card double-pass, double-receiving double-card double-standby and the like. Taking the SIM card #1 and the SIM card #2 of the plurality of SIM cards as an example, for example, when the terminal uses the SIM card #1 to communicate, the terminal sends the SRS through the port #1, and in this process, the SIM card #2 is started and occupies the port #1, so that the terminal cannot send the SRS smoothly using the port # 1.

In one embodiment, the indication information includes, but is not limited to, downlink control information DCI, a medium access control layer control element MAC CE, and the like.

in step S601, receiving srs-txport switch capability information sent by the terminal;

in step S602, the indication information is generated according to the capability information.

In one embodiment, as the capabilities of the srs-txport switch of the terminal change, the support of the receiving antenna and the transmitting antenna by the terminal also changes, so the terminal may report srs-txport switch capability information to the network device after determining the current srs-txport switch capability.

Fig. 7 is a schematic flow chart diagram illustrating yet another port switch indication method according to an embodiment of the present disclosure. As shown in fig. 7, the method further includes:
