Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method, communication device, and network equipment. Background Technology

[0002] With the development of wireless communication technology, various new services are emerging, and different services have different resource requirements. This necessitates that future wireless networks enable various services to utilize limited channel resources more efficiently. In Long Term Evolution (LTE) and 5G New Radio (NR) systems, the Sounding Reference Signal (SRS) is a crucial uplink signal. After a User Equipment (UE) establishes a connection with the base station, the base station can allocate SRS resources to the UE and then estimate the uplink channel quality based on the SRS transmitted by the UE. Specifically, in Time Division Duplex (TDM) systems, based on the reciprocity of uplink and downlink channels, the base station can also estimate the downlink channel quality based on the SRS transmitted by the UE, and then perform downlink beamforming. Due to the time-varying characteristics of wireless communication channels, if the transmission period of the currently configured periodically transmitted or semi-statically transmitted SRS is longer, the SRS signal-to-noise ratio will be weaker, thus affecting the user's channel estimation and throughput. However, if the transmission period is shorter, the SRS resources will be insufficient to allocate to every user.

[0003] In existing technologies, the theoretically usable range of SRS resources for each user within a cell is limited. When allocating SRS resources to users within a cell, base stations often only consider the capability indication information reported by the user upon access and the current status of base station resources, allocating unallocated SRS resources within the usable range. This one-time allocation method, performed only upon user access, results in poor flexibility and utilization efficiency in SRS resource usage. Summary of the Invention

[0004] The technical problem to be solved by the embodiments of this application is to provide a communication method, communication device and network to solve the problems of limited SRS resources, inflexible allocation and poor utilization efficiency.

[0005] In a first aspect, embodiments of this application provide a communication method, which may include:

[0006] The terminal sends a first indication information to the network device, the first indication information indicating an updated SRS transmission port switching mode supported by the terminal, the updated SRS transmission port switching mode supported by the terminal including at least one antenna switching capability;

[0007] The terminal receives antenna switching type SRS resource configuration information from the network device.

[0008] After the terminal completes access, it can be dynamically triggered to send indication information to the base station based on its own status or changes in the external environment, informing the terminal of its current capabilities or current SRS resource requirements. This allows the base station to dynamically adjust the SRS resources allocated to the terminal, thereby improving the flexibility of SRS resource allocation and the utilization rate of SRS resources.

[0009] In one possible implementation, the terminal sends first indication information to the network device, including:

[0010] If the terminal determines that the preset conditions are met, it sends the first indication information to the network device so that the network device reduces the SRS resources allocated to the terminal.

[0011] The preset conditions include at least one of the following:

[0012] The temperature of the terminal reaches the preset temperature;

[0013] The terminal's battery level has reached the preset level;

[0014] At least one antenna of the terminal malfunctioned.

[0015] When a terminal meets the above preset conditions, it can send a first indication message to the base station, so that the base station can know the status of the terminal. For terminals with reduced capabilities or needs, the allocation of SRS resources can be dynamically reduced, thereby expanding the user capacity of the base station and enabling newly connected terminals to obtain sufficient SRS resources, thus improving the flexibility and utilization of SRS allocation.

[0016] In one possible implementation, if the algorithm for allocating SRS resources on the network device side is fixed, for example, the network device allocates SRS resources based on the maximum antenna switching capability reported by the terminal, then before the terminal sends the first indication information to the network device, the method further includes:

[0017] The terminal sends a second indication information to the network device. The second indication information indicates the SRS transmission port switching mode supported by the terminal. The SRS transmission port switching mode supported by the terminal includes at least one antenna switching capability. The at least one antenna switching capability included in the SRS transmission port switching mode supported by the terminal corresponds to SRS resources, wherein the largest SRS resource is the first SRS resource.

[0018] The maximum SRS resource corresponding to at least one antenna switching capability in the updated SRS transmit port switching modes supported by the terminal is less than the first SRS resource.

[0019] In another possible implementation, if there are multiple algorithms for allocating SRS resources on the network device side, then to ensure that the network device reduces the SRS resources allocated to the terminal, the method further includes the following before the terminal sends the first indication information to the network device:

[0020] The terminal sends a second indication information to the network device. The second indication information indicates the SRS transmission port switching mode supported by the terminal. The SRS transmission port switching mode supported by the terminal includes at least one antenna switching capability. The at least one antenna switching capability included in the SRS transmission port switching mode supported by the terminal corresponds to SRS resources, wherein the smallest SRS resource is the first SRS resource.

[0021] The SRS resources corresponding to at least one antenna switching capability included in the updated SRS transmission port switching modes supported by the terminal are all less than the first SRS resource.

[0022] This ensures that regardless of the algorithm used by the network device to allocate SRS resources, it will reduce the SRS resources allocated to the terminal after receiving the first instruction information.

[0023] In one possible implementation, the terminal sends first indication information to the network device, including:

[0024] If the terminal determines that the preset conditions are not met, it sends the first indication information to the network device so that the network device increases the SRS resources allocated to the terminal.

[0025] The preset conditions include at least one of the following:

[0026] The temperature of the terminal reaches the preset temperature;

[0027] The terminal's battery level has reached the preset level;

[0028] At least one antenna of the terminal malfunctioned;

[0029] The terminal accesses the network device for a time shorter than a preset time.

[0030] When a terminal does not meet the above preset conditions, it can send a first indication message to the base station so that the base station can know the status of the terminal. For terminals with improved or restored capabilities or needs, the allocation of SRS resources can be dynamically increased, thereby improving the throughput and communication quality of the terminal and enhancing the flexibility and utilization of SRS allocation.

[0031] In one possible implementation, if the algorithm for allocating SRS resources on the network device side is fixed, for example, the network device allocates SRS resources based on the maximum antenna switching capability reported by the terminal, then before the terminal sends the first indication information to the network device, the method further includes:

[0032] The terminal sends a second indication information to the network device. The second indication information indicates the SRS transmission port switching mode supported by the terminal. The SRS transmission port switching mode supported by the terminal includes at least one antenna switching capability. The at least one antenna switching capability included in the SRS transmission port switching mode supported by the terminal corresponds to SRS resources, wherein the largest SRS resource is the first SRS resource.

[0033] The maximum SRS resource corresponding to at least one antenna switching capability in the updated SRS transmission port switching modes supported by the terminal is greater than the first SRS resource.

[0034] In another possible implementation, if there are multiple algorithms for allocating SRS resources on the network device side, then to ensure that the network device increases the SRS resources allocated to the terminal, the method further includes the following steps before the terminal sends the first indication information to the network device:

[0035] The terminal sends a second indication information to the network device. The second indication information indicates the SRS transmission port switching mode supported by the terminal. The SRS transmission port switching mode supported by the terminal includes at least one antenna switching capability. The at least one antenna switching capability included in the SRS transmission port switching mode supported by the terminal corresponds to SRS resources, wherein the smallest SRS resource is the first SRS resource.

[0036] The SRS resources corresponding to at least one antenna switching capability included in the updated SRS transmission port switching modes supported by the terminal are all greater than the first SRS resource.

[0037] This ensures that regardless of the algorithm used by the network device to allocate SRS resources, it will increase the SRS resources allocated to the terminal after receiving the first instruction information.

[0038] In one possible implementation, the first indication information is carried in user equipment auxiliary information or overheat protection information.

[0120] The embodiments of this application will now be described with reference to the accompanying drawings.

[0121] The terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0122] For ease of explanation, the embodiments of the present invention are described using LTE or NR systems. The implementation methods in the embodiments of the present invention are also applicable to other existing communication systems and future higher-level communication systems such as 6G and 7G. The embodiments of the present invention do not impose any limitations.

[0123] Please refer to Figure 1 This is a schematic diagram of the architecture of a communication system according to an embodiment of this application. It may include network devices and communication devices. For ease of explanation, in... Figure 1 The example uses a network device as a base station 10 and a communication device as a terminal 20. Under this architecture, it may include a base station 10 and at least one terminal 20.

[0124] In this context, a network device refers to a device in an access network that communicates with terminals via sectors on the air interface. Network devices can be used to convert received air frames to and from Internet Protocol (IP) packets, acting as routers between terminal devices and the rest of the access network, which includes the IP network. Network devices can also coordinate the attribute management of the air interface. For example, network equipment can be a base station (BTS) in Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA), a base station in Wideband Code Division Multiple Access (WCDMA), an evolved base station in LTE, or an access point (AP), relay station, vehicle-mounted equipment, wearable devices, and network equipment in future 5G networks or future evolved PLMN networks. Examples include base stations that can connect to 5G core network equipment, transmission and reception points (TRPs), centralized units (CUs), and distributed units (DUs). No specific limitations are imposed here.

[0125] Taking a network device as a base station as an example, base station 10 can be an NR base station (gNB), an evolved NodeB (eNB), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a Home Evolved NodeB (HNB), a Base Band Unit (BBU), etc. It can also be referred to by those skilled in the art as a base transceiver, wireless base station, wireless transceiver, transceiver function, base station subsystem (BSS), or some other appropriate terms. It is an entity on the network side used to transmit or receive signals. In the embodiments of this application, base station 10 can receive indication information sent by the terminal, and make decisions based on the overall SRS resource usage status and the indication information sent by the terminal to determine the SRS resources allocated to the terminal.

[0126] Terminal 20 can also be called User Equipment (UE). It can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on water (such as on ships); and it can also be deployed in the air (such as on airplanes, balloons, and satellites). It can also be called a user terminal, terminal equipment, access terminal equipment, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal equipment, mobile device, UE terminal equipment, mobile terminal, wireless communication equipment, UE agent, or UE device, etc. The terminal can also be fixed or mobile. Specifically, these can take the form of mobile phones, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, vehicle-mounted terminal devices, wireless terminals in self-driving vehicles, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, wearable terminal devices, etc. It is a user-side entity used for receiving or transmitting signals. In this embodiment, terminal 20 can send indication information to base station 10, informing the base station of the SRS transmission port switching modes supported by the terminal. The SRS transmission port switching modes supported by the terminal include at least one antenna switching capability. The size of the SRS resources corresponding to the antenna switching capability is related to the number of SRS resources and the number of ports of the SRS resources. This allows the base station to know the current capabilities of the terminal and dynamically adjust the allocation of SRS resources.

[0127] For the sake of simplicity, this application embodiment only shows one terminal 20. In actual scenarios, the number of terminals 20 can be one or more. Some terminals can also act as relay devices to relay messages for other terminals, and terminals can also form user groups, etc. This application embodiment does not make any limitations.

[0128] The following is in conjunction with the appendix Figures 2-8 The communication method and device of the present invention will be described in detail.

[0129] Please see Figure 2 , Figure 2 This is a flowchart illustrating a communication method provided in an embodiment of this application. It includes the following steps:

[0130] S201, the terminal sends the first indication information to the base station.

[0131] The first indication information indicates the updated SRS transmission port switching mode supported by the terminal, and the updated SRS transmission port switching mode supported by the terminal includes at least one antenna switching capability.

[0132] S202, the terminal receives antenna switching type SRS resource configuration information from the base station.

[0133] In step S201, after the terminal connects to the base station, its operating state and the external environment may change dynamically. This will cause the terminal's demand for SRS resources to change. For example, as the terminal's operating time continues, its battery level will gradually decrease. When it drops to a certain battery threshold, the terminal can enter energy-saving mode, at which point its demand for SRS resources may decrease accordingly. Conversely, when the terminal is charged and its battery level recovers above the threshold, its demand for SRS resources may increase accordingly. Therefore, the first indication information can be used to notify the base station of the terminal's current demand for SRS resources.

[0134] In one possible implementation, the SRS transmit port switching mode supported by the terminal during initial access can be indicated by the supportedSRS-TxPortSwitch information element. For example, the field indicating antenna switching capability can be: t1r1-t1r2, t1r1-t1r2-t1r4, t1r1-t1r2-t2r2-t2r4, t1r1-t1r2-t2r2-t1r4-t2r4, t1r1-t2r2, t1r1-t2r2-t4r4, etc. When the field is t1r1-t1r2, it indicates that the terminal supports both t1r1 and t1r2 antenna switching capabilities. t1r1 represents that the terminal supports 1 transmit and 1 receive antenna switching capability, and t1r2 represents that the terminal supports 1 transmit and 2 receive antenna switching capability.

[0135] When the field in the supportedSRS-TxPortSwitch cell is notsupport, it means that the terminal does not support the antenna switching (AS) type of SRS.

[0136] When a terminal determines that preset conditions are met, it can send a first indication message to the base station, so that the base station can dynamically adjust the allocation of SRS resources based on the first indication message sent by the terminal. For example, the terminal can report updated SRS transmission port switching modes supported by the terminal through the ReducedMaxSrs-TxPortSwitch information cell or IncreasedMaxSrs-TxPortSwitch, so that the base station can correspondingly reduce or increase the allocation of SRS resources.

[0137] For example, the SRS resources corresponding to antenna switching capability can be understood as the SRS resources allocated by the base station to the terminal so that the terminal can work in a certain antenna switching capability. The SRS resources can include n SRS resources, and each of the n SRS resources can correspond to m ports. Therefore, the size of the SRS resources corresponding to antenna switching capability can be measured by the product of n and m (n*m). The larger the product, the larger the SRS resources corresponding to the antenna switching capability.

[0138] For example, antenna switching capability corresponds to SRS resources. That is, when a terminal operates with a certain antenna switching capability, the base station can allocate SRS resources corresponding to that antenna switching capability to the terminal. The size of the SRS resources corresponding to the antenna switching capability is related to the number of SRS resources and the number of ports of each SRS resource. Typically, the base station allocates n SRS resources to the terminal and m SRS resources of each with the corresponding number of ports. The antenna switching capability t of the terminal corresponds to n and m. x r y It must belong to one of the SRS transmit port switching modes supported by the updated terminal. Generally, m = x, n = y / x. For example, if the updated antenna switching capability of the terminal is t1r2, then the number of AS resources n allocated according to this capability is equal to 2, and the number of transmit ports for each SRS resource is equal to 1.

[0139] In another possible implementation, the terminal can report the maximum number of uplink multiple-input multiple-output (MIMO) layers of the codebook (CB) type SRS supported by the terminal to the base station during initial access. For example, the maximum number of uplink MIMO layers of the CB type SRS initially supported by the terminal can be reported through the maxNumberMIMO-LayersCB-PUSCH cell. The possible values ​​of maxNumberMIMO-LayersCB-PUSCH are as follows:

[0140] OneLayer, twoLayers, and fourLayers. OneLayer indicates the terminal supports a maximum of one uplink MIMO layer, twoLayers indicates two, and fourLayers indicates four. When the terminal determines that preset conditions are met, it can send a first indication message to the base station, allowing the base station to dynamically adjust the allocation of SRS resources based on this message. For example, the terminal can report updated maximum uplink MIMO layers it supports via ReducedMaxMIMO-Layers or IncreasedMaxMIMO-Layers cells, enabling the base station to correspondingly reduce or increase the allocation of SRS resources.

[0141] Specifically, if the number of ports of the CB-type SRS resource allocated by the base station to the terminal is m, then m is less than or equal to the maximum number of uplink MIMO layers supported by the terminal. Generally, the base station will allocate one CB-type SRS resource to the terminal, i.e., n = 1. Assuming the maximum number of uplink MIMO layers supported by the terminal is twoLayers, then the number of ports m of the SRS resource allocated by the base station to the terminal is 1 or 2.

[0142] In another possible implementation, the terminal can report the maximum number of uplink multiple-input multiple-output (MIMO) layers for non-codebook (non-CB) SRS supported by the terminal to the base station during initial access. For example, the maximum number of uplink MIMO layers for CB-type SRS initially supported by the terminal can be reported through the maxNumberMIMO-LayersNonCB-PUSCH cell. The possible values ​​of maxNumberMIMO-LayersNonCB-PUSCH are as follows:

[0143] OneLayer, twoLayers, and fourLayers. OneLayer indicates the terminal supports a maximum of one uplink MIMO layer, twoLayers indicates two, and fourLayers indicates four. When the terminal determines that preset conditions are met, it can send a first indication message to the base station, allowing the base station to dynamically adjust the allocation of SRS resources based on this message. For example, the terminal can report updated maximum uplink MIMO layers it supports via ReducedMaxMIMO-Layers or IncreasedMaxMIMO-Layers cells, enabling the base station to correspondingly reduce or increase the allocation of SRS resources.

[0144] Specifically, if the number of ports of the non-CB type SRS resource allocated by the base station to the terminal is m, then m is less than or equal to the maximum number of uplink MIMO layers supported by the terminal. Generally, the base station will allocate one non-CB type SRS resource to the terminal, i.e., n = 1. Assuming that the maximum number of uplink MIMO layers supported by the terminal is twoLayers, then the number of ports m of the SRS resource allocated by the base station to the terminal is 1 or 2.

[0145] The above three possible implementation methods can be carried out simultaneously or independently according to the SRS type supported by the terminal. This application embodiment does not impose any limitations.

[0146] In the three possible implementations mentioned above, the terminal can also report the maximum number of ports corresponding to a single SRS resource that the terminal can initially support via maxNumberSRS-Ports-PerResource during initial access. The possible values ​​for maxNumberSRS-Ports-PerResource are as follows:

[0147] 1,2,4.

[0148] When the terminal determines that preset conditions are met, it can send a first indication message to the base station, allowing the base station to dynamically adjust the allocation of SRS resources based on this message. For example, the terminal can report the updated maximum number of ports corresponding to a single SRS resource that the UE can support via reducedmaxNumberSRS-Ports-PerResource or IncreasedmaxNumberSRS-Ports-PerResource. This allows the base station to reduce or increase the allocation of SRS resources accordingly.

[0149] If the number of ports of any type of SRS resource allocated by the base station to the terminal is m, then m is less than or equal to the maximum number of ports corresponding to a single SRS resource that the terminal can support.

[0150] Typically, an SRS with two ports occupies more resources than an SRS with one port. However, the resources occupied by two SRSs with one port can be the same as those occupied by one SRS with two ports. Optionally, the base station can define that two SRSs with one port occupy more resources than one SRS with two ports. For example, the resource occupancy can be ordered in the order t1r1 < t1r2 < t2r2 < t2r4. The base station can flexibly and dynamically adaptively allocate SRS resources according to the terminal's reporting capabilities and the current status of SRS resources on the network side, thereby improving the flexibility and utilization of SRS resource allocation.

[0151] Optionally, the first indication information may be carried in the user equipment assistance information (UE Assistance Information) or the overheating assistance information.

[0152] After the terminal completes access, it can be dynamically triggered to send indication information to the base station based on its own status or changes in the external environment, informing the terminal of its current capabilities or current SRS resource requirements. This allows the base station to dynamically adjust the SRS resources allocated to the terminal, thereby improving the flexibility of SRS resource allocation and the utilization rate of SRS resources.

[0153] Since the terminal's operating status may change from normal to abnormal, or vice versa, the dynamic adjustment of SRS resources can be divided into two main categories. The following section combines... Figure 3 and Figure 4 Please provide a detailed explanation.

[0154] Please see Figure 3 The following is a flowchart illustrating another communication method provided in an embodiment of this application; it includes the following steps:

[0155] S301, the terminal sends a second instruction message to the base station.

[0156] The second indication information indicates the SRS transmission port switching mode supported by the terminal. The SRS transmission port switching mode supported by the terminal includes at least one antenna switching capability. The at least one antenna switching capability included in the SRS transmission port switching mode supported by the terminal corresponds to SRS resources, wherein the largest SRS resource is the first SRS resource.

[0157] S302, the terminal receives the first antenna switching type SRS resource configuration information from the base station.

[0158] S303, the terminal sends SRS based on the SRS resources allocated by the SRS resource configuration information of the first antenna switching type.

[0159] S304, if the terminal determines that the preset conditions are met, it sends the first indication information to the base station.

[0160] At this time, the first indication information is used to reduce the SRS resources of the terminal.

[0161] Since there are many algorithms for base stations to allocate SRS resources to terminals, in order to reduce the SRS resources required by terminals, the following different methods can be used for different SRS resource allocation algorithms:

[0162] When the base station allocates SRS resources to the terminal based on the maximum antenna switching capability reported by the terminal, the first indication information indicates an updated SRS transmission port switching mode supported by the terminal. The updated SRS transmission port switching mode supported by the terminal includes at least one antenna switching capability, and each of these at least one antenna switching capability corresponds to an SRS resource, wherein the maximum SRS resource is less than the first SRS resource. In this case, the SRS resources allocated to the terminal can be reduced accordingly.

[0163] Of course, there are many algorithms for base stations to allocate SRS resources to terminals. For example, the base station can allocate SRS resources to the terminal based on the maximum antenna switching capability reported by the terminal, or based on the median or average of multiple antenna switching capabilities reported by the terminal, or based on the terminal's service type, such as high-bandwidth / low-bandwidth, high-speed / low-speed, etc. In this case, to ensure that the base station reduces the SRS resources allocated to the terminal, the first indication information indicates an updated SRS transmission port switching mode supported by the terminal. The updated SRS transmission port switching mode supported by the terminal includes at least one antenna switching capability, and the SRS resources corresponding to each of the at least one antenna switching capability included in the updated SRS transmission port switching mode supported by the terminal are all less than the first SRS resource. Therefore, regardless of the algorithm used by the network device to allocate SRS resources, it will reduce the SRS resources allocated to the terminal after receiving the first indication information.

[0164] The preset conditions include at least one of the following:

[0165] The terminal reaches a preset temperature; this preset temperature can be a single value or multiple values, and the corresponding SRS resource adjustment can also be divided into multiple levels. For example, when the terminal temperature reaches 40 degrees Celsius, the allocation of SRS resources is reduced; when it reaches 60 degrees Celsius, the allocation of SRS resources can be further reduced. When the temperature decreases, the adjustment of SRS resources can also be divided into multiple levels.

[0166] The terminal's battery level reaches a preset level; this preset temperature can be a single value or multiple values, and the corresponding SRS resource adjustment can also be divided into multiple levels. For example, when the terminal's battery level drops to 20%, the allocation of SRS resources is reduced; when it drops to 5%, the allocation of SRS resources can be further reduced. When the battery level increases, the adjustment of SRS resources can also be divided into multiple levels.

[0167] At least one antenna of the terminal has failed. Here, the adjustment of the corresponding SRS resources can be divided into multiple levels based on the number of failed antennas. For example, if one antenna fails, the allocation of SRS resources is reduced; if two antennas fail, the allocation of SRS resources can be further reduced. When the failed antennas return to normal, the adjustment of SRS resources can also be divided into multiple levels based on the number of antennas that have returned to normal.

[0168] S305, the terminal receives second antenna switching type SRS resource configuration information from the base station.

[0169] The SRS resources allocated by the base station to the terminal in the second antenna switching type SRS resource configuration information are less than the SRS resources currently used by the terminal.

[0170] For example, for AS-type SRS users that support t1r1, t2r2, and t2r4 antenna switching capabilities, if the base station initially allocates t2r4 antenna switching capabilities (i.e., 2 SRS resources, each with 4 ports) to the terminal's SRS resources, the allocation can be adjusted to the terminal's SRS resources when the terminal meets the aforementioned preset conditions. For example, the adjusted SRS resources might correspond to 2t2r (i.e., 1 SRS resource with 2 ports) or 1T1R (i.e., 1 SRS resource with 1 port).

[0171] For CB type SRS users, if the base station initially allocates 4 ports for SRS resources to the terminal, the number of SRS resources allocated to the terminal can be adjusted later when the terminal meets the above-mentioned preset conditions. For example, the number of ports for the adjusted SRS resources may be 2 or 1.

[0172] For non-CB type SRS users, if the base station initially allocates 4 ports for SRS resources to the terminal, the number of SRS resources allocated to the terminal can be adjusted later when the terminal meets the above-mentioned preset conditions. For example, the number of ports in the adjusted SRS resources may be 2 or 1.

[0173] By adjusting in the above way, the allocation of SRS resources can be dynamically reduced for terminals with reduced capabilities or needs, thereby expanding the user capacity of the base station, enabling newly connected terminals to obtain sufficient SRS resources, and improving the flexibility and utilization of SRS allocation.

[0174] Please see Figure 4 This is a flowchart illustrating another communication method provided in an embodiment of this application; it includes the following steps:

[0175] S401, the terminal sends a second instruction message to the network device.

[0176] The second indication information indicates the SRS transmission port switching mode supported by the terminal. The SRS transmission port switching mode supported by the terminal includes at least one antenna switching capability. The at least one antenna switching capability included in the SRS transmission port switching mode supported by the terminal corresponds to SRS resources, wherein the largest SRS resource is the first SRS resource.

[0177] S402, if a terminal that previously met the preset conditions determines that it no longer meets the preset conditions, then the first indication information is sent to the network device.

[0178] At this time, the first instruction information is used to increase the SRS resources of the terminal.

[0179] Since there are many algorithms for base stations to allocate SRS resources to terminals, in order to increase the SRS resources of terminals, the following different methods can be used for different SRS resource allocation algorithms:

[0180] When the base station allocates SRS resources to the terminal based on the maximum antenna switching capability reported by the terminal, the first indication information indicates an updated SRS transmission port switching mode supported by the terminal. The updated SRS transmission port switching mode supported by the terminal includes at least one antenna switching capability, and each of these at least one antenna switching capability corresponds to an SRS resource, wherein the maximum SRS resource is greater than the first SRS resource. At this time, the SRS resources allocated to the terminal can be increased accordingly.

[0181] Of course, there are many other algorithms for base stations to allocate SRS resources to terminals. For example, the base station can allocate SRS resources to the terminal based on the maximum antenna switching capability reported by the terminal, or based on the median or average of multiple antenna switching capabilities reported by the terminal, or based on the terminal's service type, such as high-bandwidth / low-bandwidth service, high-speed / low-speed service, etc. In this case, to ensure that the base station increases the SRS resources allocated to the terminal, the first indication information indicates the updated SRS transmission port switching mode supported by the terminal. The updated SRS transmission port switching mode supported by the terminal includes at least one antenna switching capability, and the SRS resources corresponding to each of the at least one antenna switching capability included in the updated SRS transmission port switching mode supported by the terminal are all greater than the first SRS resource.

[0182] This ensures that regardless of the algorithm used by the network device to allocate SRS resources, it will increase the SRS resources allocated to the terminal after receiving the first instruction information.

[0183] The preset conditions include at least one of the following:

[0184] The temperature of the terminal reaches the preset temperature;

[0185] The terminal's battery level has reached the preset level;

[0186] At least one antenna of the terminal malfunctioned;

[0187] The terminal accesses the base station for a time shorter than a preset time. This preset time can be a single value or multiple values, and the corresponding SRS resource adjustments can be divided into multiple levels.

[0188] S403, the terminal receives antenna switching type SRS resource configuration information from the base station.

[0189] The base station allocates more SRS resources to the terminal in the antenna switching type SRS resource configuration information than the SRS resources currently used by the terminal.

[0190] For example, for AS-type SRS users that support t1r1 and t2r2 antenna switching capabilities, if the base station initially allocates t2r2 antenna switching capability (i.e., 1 SRS resource with 2 ports) to the terminal, the SRS resources allocated to the terminal can be adjusted if the terminal does not meet the above preset conditions. For example, the adjusted SRS resources may correspond to 2t4r antenna switching capability (i.e., 2 SRS resources with 4 ports).

[0191] For CB type SRS users, if the base station initially allocates 1 port for SRS resources to the terminal, the SRS resources allocated to the terminal can be adjusted if the terminal does not meet the above preset conditions. For example, the adjusted SRS resources may have 2 ports or 4 ports.

[0192] For non-CB type SRS users, if the base station initially allocates 1 port for SRS resources to the terminal, the SRS resources allocated to the terminal can be adjusted if the terminal does not meet the above preset conditions. For example, the adjusted SRS resources may have 2 or 4 ports.

[0193] By adjusting in the above way, the allocation of SRS resources can be dynamically increased for terminals whose capabilities or needs are improved or restored, thereby improving the throughput and communication quality of the terminals and enhancing the flexibility and utilization of SRS allocation.

[0194] When the terminal meets the above preset conditions again, it can refer to Figure 3 The steps in the described embodiment involve sending the instruction information again to cause the base station to reduce the allocation of SRS resources.

[0195] It should be noted that in this application Figure 3 and Figure 4 In the embodiments described, the allocation of SRS resources is typically reduced when the terminal capability is reduced and increased when the terminal capability is improved. In other communication scenarios, such as satellite communication scenarios, in order to ensure the quality of terminal communication and the normal operation of communication, the allocation of SRS resources can also be increased when the terminal capability is reduced. This application embodiment does not make any limitation.

[0196] In addition, the method described in this application embodiment can be used not only to dynamically adjust the allocation of SRS resources, but also to dynamically adjust the allocation of other resources according to changes in terminal capabilities. This application embodiment does not impose any limitations on this method.
