Detailed Description
The embodiment of the application provides a method for reporting capability, which is used in a process that network equipment configures SRS resources for User Equipment (UE). Specifically, the method is applied to the process of configuring corresponding SRS resources when network equipment configures MIMO layer number or antenna port number for UE. Since the network device does not know the SRS antenna switching capability corresponding to the capability supported by the configured MIMO layer number or antenna port number when configuring the MIMO layer number or antenna port number for the UE, the SRS resource supporting the corresponding SRS antenna switching capability is not configured for the UE.
For example: when the overheating problem occurs to the UE, the network equipment is requested to reduce the MIMO layer number of the UE to relieve the overheating problem. After the network device turns down the MIMO layer for the UE, the UE may close the corresponding radio frequency link; for example: if the network equipment reduces the uplink maximum MIMO layer number of the UE, the UE closes the corresponding radio frequency transmission link; if the network device decreases the downlink maximum MIMO layer number of the UE, the UE may close the corresponding radio frequency receiving link. However, if the network device does not correspondingly reconfigure the SRS resources for user antenna port conversion, after the UE closes the corresponding radio frequency transmission link, the UE may not support antenna round robin under normal capability, thereby resulting in waste of some SRS resources; after the UE closes the corresponding radio frequency receiving link, if the UE still transmits SRS according to the antenna under normal capability, the channel quality estimated by the network device according to SRS will not be consistent with the channel quality of PDSCH transmission scheduled by the network device.
The application aims at reporting the retrogressive SRS antenna conversion capability supported by the UE to the network equipment, so that the network equipment can configure corresponding SRS resources according to the retrogressive SRS antenna conversion capability reported by the UE.
The method of the embodiment of the application can be applied to a third Generation (3 rd-Generation, 3G) mobile communication network, a fourth Generation (4 th-Generation, 3G) mobile communication network long term evolution (Long Term Evolution, LTE) network and a fifth Generation (5 th-Generation, 5G) mobile communication system New wireless (NR) network. The above method may also be applied in the next generation cellular mobile communication system, and in the subsequent other mobile communication systems, which is not limited in this application.
The network device in the method of the embodiment of the present application may be a base station. Such as macro base stations, micro base stations, or distributed unit-control units (DU-CUs), etc. Wherein the DU-CU is a device deployed in the radio access network and capable of wireless communication with the user equipment. The base station may be configured to configure the MIMO layer number or the antenna port number for the UE, or configure SRS resources for SRS antenna port conversion for the UE.
The base station may be an evolved node b (evolutional Node B, eNB or e-NodeB) in LTE, or may be a gNB in NR, etc. The base station may also be a wireless controller in a cloud wireless access network (cloud radio access network, CRAN) scenario, or may be a relay station, an access point, a vehicle-mounted device, a wearable device, or a network device in a future evolved public land mobile network (public land mobile network, PLMN) network, etc., which embodiments of the present application are not limited.
The UE in the method of the embodiment of the present application may be a smart phone, a tablet computer, a smart tv box from a morphological aspect, and may also be other desktop, laptop, and handheld devices, for example, ultra-mobile personal computers (Ultra-mobile Personal Computer, UMPC), netbooks, personal digital assistants (Personal Digital Assistant, PDA), portable multimedia players (Portable Multimedia Player, PMP), dedicated media players, consumer electronics devices, wearable devices, AR (augmented reality)/VR (virtual reality) devices, and so on, which is not limited in the embodiment of the present application.
For example, the method of the embodiment of the application can be applied to a process that the network equipment actively configures SRS resources for the UE. After the UE first accesses the network device, the network device may actively configure SRS resources for the UE for SRS antenna port conversion. For another example, the method of the embodiment of the present application may be applied in a process that the network device configures SRS resources for the UE in response to a request of the UE. Under the conditions of overlarge load and insufficient electric quantity or the condition that the UE expects to reduce power due to various reasons, the UE can request the network equipment to reconfigure the MIMO layer number or the antenna port number and the corresponding reconfiguration SRS resource for the UE. In the embodiment of the present application, the condition or the opportunity for triggering the network device to configure SRS resources for the UE is not limited.
As shown in fig. 1A, a schematic diagram of a possible application scenario is provided in the present application. The UE (e.g., the mobile phone 100) may actively request the network device (e.g., the base station 200) to configure SRS resources for the UE when the remaining power (e.g., the remaining power is 30%) is lower than a preset threshold (e.g., the preset threshold is 35%). Specifically, the mobile phone 100 may request the base station 200 to reduce the MIMO layer number/antenna port number of the mobile phone 100, so as to reduce the power of the mobile phone 100 during subsequent transmission and reception, and save the electric quantity.
It should be noted that, in fig. 1A, the use scenario of the embodiment of the present application is described by taking the user equipment as the mobile phone 100 and the network equipment as the base station 200 as an example, and the specific forms of the user equipment and the network equipment are not limited, and the user equipment and the network equipment may be any one of those listed above.

The following describes, with reference to fig. 1A and fig. 1B, a method for reporting a capability provided in an embodiment of the present application, where the basic principle of the method is: the UE reports the backspacing SRS antenna switching capability supported by the UE to the network equipment, so that the network equipment correspondingly reconfigures SRS resources for the UE when the number of MIMO layers or the number of antenna ports are required to be reconfigured for the UE.
It should be noted that, in the following embodiments, only the user equipment is taken as the mobile phone 100, and the network equipment is taken as the base station 200 as an example, in fact, the same manner and method may be adopted to report the capability to the network equipment for any user equipment UE, including several UEs listed above.
The embodiment of the application provides a method for reporting capability.
In a first embodiment, as shown in fig. 2, the method may include: the handset 100 sends a first message to the base station 200. The first message includes SRS antenna switching capabilities supported by the handset 100.
The first message may further include a retrogressive SRS antenna conversion capability supported by the mobile phone 100.
The mobile phone 100 reports the supported SRS antenna conversion capability and the supported retrogressive SRS antenna conversion capability to the base station 200 through the first message, so that when the base station 200 reconfigures the MIMO layer number for the mobile phone 100, the SRS resource for antenna port conversion can be reconfigured for the mobile phone 100 according to the retrogressive SRS antenna conversion capability supported by the mobile phone 100.
For example, the mobile phone 100 may send the first message to the base station 200 when the remaining power (30%) of the mobile phone 100 is lower than a preset threshold (35%) or when the mobile phone 100 is powered on for the first time.
As shown in fig. 2, when configuring/reconfiguring the MIMO layer number for the mobile phone 100, the base station 200 may refer to the backspacing SRS antenna switching capability supported by the mobile phone 100 in the first message to configure SRS resources for antenna port switching for the corresponding mobile phone 100.
In one possible implementation, the retrospective SRS antenna switching capability is reported by the mobile phone 100 according to its hardware implementation and/or the current SRS resource configuration situation. For example, the current SRS antenna switching capability of the mobile phone 100 is configured as 2T4R, i.e., the mobile phone 100 is capable of transmitting SRS over 2 antenna ports through 4 antennas; accordingly, the retrogressive SRS antenna switching capability supported by the mobile phone 100 may be 1T4R and/or 1T2R, that is, the SRS antenna switching capability of the mobile phone 100 is to transmit SRS on 1 antenna port through 4 antennas and/or the SRS antenna switching capability of the mobile phone 100 is to transmit SRS on 1 antenna port through 2 antennas.
In another possible implementation, the first message may further include a first MIMO layer number supported by the handset 100; the backspacing SRS antenna switching capability corresponds to the second MIMO layer number. The second MIMO layer number is less than or equal to the first MIMO layer number.
In this embodiment, the foregoing ways of carrying the first MIMO layer number supported by the mobile phone 100 in the first message may at least include the following two implementation ways:
implementation mode (1): the first MIMO layer number supported by the handset 100 is used to identify a maximum MIMO layer number supportable by the handset 100. The first MIMO layer number is not only the uplink maximum MIMO layer number supported by the mobile phone 100, but also the downlink maximum MIMO layer number supported by the mobile phone 100.
For example, assuming that the first MIMO layer number is 8, the base station 200 may determine that the uplink maximum MIMO layer number and the downlink maximum MIMO layer number supported by the mobile phone 100 are both 8.
In implementation (1), in combination with the above example, the second MIMO layer number may be less than or equal to the first MIMO layer number, and the MIMO layer number supported by the handset 100. For example, if the number of MIMO layers supported by the handset 100 includes 1,2,4, 8; the second MIMO layer number may be any one of 1,2,4,8 MIMO layers. The second MIMO layer number is applicable to both uplink and downlink.
Implementation mode (2): the first MIMO layer number supported by the handset 100 may include: the uplink maximum MIMO layer number supported by the handset 100 and the downlink maximum MIMO layer number supported by the handset 100.
For example: the number of uplink maximum MIMO layers supported by the handset 100 is 4, and the number of downlink maximum MIMO layers supported by the handset 100 is 8. Then, the first MIMO layer number may include: uplink maximum MIMO layer number 4 supported by handset 100 and downlink maximum MIMO layer number 8 supported by handset 100.
In implementation (2), in combination with the above example, the number of uplink second MIMO layers may be less than or equal to the number of uplink first MIMO layers, and the number of MIMO layers supported by the handset 100. For example, if the uplink MIMO layer number supported by the handset 100 includes 1,2,4; the second MIMO layer number of the uplink may be 1,2 or 4. The number of downlink second MIMO layers may be less than or equal to the number of downlink first MIMO layers, and the number of MIMO layers supported by the handset 100. For example, if the number of downlink MIMO layers supported by the handset 100 includes 1,2,4,8; the second MIMO layer number of the downlink may be any one of 1,2,4, or 8 MIMO layer numbers.
The backspacing SRS antenna conversion capability supported by the mobile phone 100 corresponds to the second MIMO layer number, which may specifically be: the retractable SRS antenna switching capability supported by the handset 100 corresponds to at least one second MIMO layer number.
The handset 100 may support at least one band combination, each band combination including a plurality of bands, e.g., the handset 100 may support band combination 1, which is a combination of band 1 (e.g., band 1 is 1800Mhz to 1810 Mhz) and band 2 (e.g., band 2 is 1820Mhz to 1830 Mhz). Each frequency band includes a plurality of carriers. The handset 100 may support a portion of the plurality of carriers described above.
Based on this, in the first scenario, the first MIMO layer number supported by the handset 100 may include: the handset 100 supports a maximum number of uplink MIMO layers and a maximum number of downlink MIMO layers on each carrier on each frequency band in each frequency band combination supported by the handset 100.
Accordingly, the second MIMO layer number may be: the handset 100 supports the number of uplink MIMO layers and/or the number of downlink MIMO layers on each carrier on each frequency band in each frequency band combination supported by the handset 100.
In the above-described implementation (2), the mobile phone 100 discriminates between uplink and downlink and notifies the base station 200 of the first MIMO layer number. In example 1, assume that the handset 100 supports two band combinations: band combination 1 (including band 1 and band 3) and band combination 2 (including band 2 and band 4). Taking band 1 in band combination 1 as an example, handset 100 supports carrier 1 and carrier 2 on band 1. The maximum uplink MIMO layer number supported by the handset 100 on carrier 1 is 4 and the maximum downlink MIMO layer number is 8. The maximum uplink MIMO layer number supported by the handset 100 on carrier 2 is 2 and the maximum downlink MIMO layer number is 4.
Correspondingly, the second MIMO layer number supported by the handset 100 on the carrier 1 is uplink MIMO layer numbers 1,2 and 4, and downlink MIMO layer numbers 1,2,4 and 8; the second MIMO layer number supported by handset 100 on carrier 2 includes uplink MIMO layer numbers 1 and 2, and downlink MIMO layer numbers 2 and 4.
In the first scenario, the SRS antenna switching capability may be of different granularity than the first MIMO layer number supported by the handset 100. For example, the SRS antenna switching capability is an SRS antenna switching capability supported by the mobile phone 100 on each frequency band.

The first retrogressive SRS antenna conversion capability corresponds to an uplink MIMO layer number in a second MIMO layer number supported by the mobile phone 100 on a corresponding carrier on a corresponding frequency band in the corresponding frequency band combination, and the second retrogressive SRS antenna conversion capability corresponds to a downlink MIMO layer number in the second MIMO layer number supported by the mobile phone 100 on a corresponding carrier on a corresponding frequency band in the corresponding frequency band combination.
Taking example 1 above as an example: the retrogressive SRS antenna switching capability supported by the mobile phone 100 includes: the first and second retractable SRS antenna switching capabilities supported by the handset 100 on carrier 1 and carrier 2, respectively, and the first and second retractable SRS antenna switching capabilities supported by the handset 100 on each of carrier 2, 3, and 4, respectively.
Taking the example of the SRS antenna switching capability supported by the mobile phone 100 on the carrier 1 on the frequency band combination 1, the SRS antenna switching capability includes two SRS antenna switching capabilities capable of being retracted; one corresponding to all uplink MIMO layers (1, including 2 and 4) supported by handset 100 on carrier 1, and one corresponding to all downlink MIMO layers (including 1,2,4 and 8) supported by handset 100 on carrier 1 in band 1.
Case (iii): the retrogressive SRS antenna switching capability supported by the mobile phone 100 includes: the handset 100 supports a first set of retractable SRS antenna switching capabilities and a second set of retractable SRS antenna switching capabilities on each carrier on each frequency band in each frequency band combination supported by the handset 100.
Wherein each of the first set of the retractable SRS antenna conversion capabilities corresponds to one uplink MIMO layer number of the second MIMO layer number supported by the mobile phone 100 on each carrier on the corresponding frequency band in the corresponding frequency band combination, and each of the second set of the retractable SRS antenna conversion capabilities corresponds to one downlink MIMO layer number of the second MIMO layer number supported by the mobile phone 100 on each carrier on the corresponding frequency band in the corresponding frequency band combination.
Taking example 1 above as an example: the retrogressive SRS antenna switching capability supported by the mobile phone 100 includes: the first set of retractable SRS antenna switching capability and the second set of retractable SRS antenna switching capability supported by the mobile phone 100 on the carrier 1 and the carrier 2, respectively, in the frequency band 1, the frequency band 3, and the frequency band 4, and the first set of retractable SRS antenna switching capability and the second set of retractable SRS antenna switching capability supported by the mobile phone 100 on all the carriers in the frequency band 2, the frequency band 3, and the frequency band 4, respectively.
Taking the backspacing SRS antenna switching capability supported by the mobile phone 100 on the carrier 1 of the frequency band 1 on the frequency band combination 1 as an example, the SRS antenna switching capability includes two groups of SRS antenna switching capability; one group includes SRS antenna capabilities corresponding to uplink MIMO layers 1,2,4 and 8 supported by the mobile phone 100 on the carrier 1, and the other group includes SRS antenna switching capabilities corresponding to downlink MIMO layers 1,2,4 and 8 supported by the mobile phone 100 on the carrier 1.
In the third scenario, the SRS antenna conversion capability supported by the mobile phone 100 and the first MIMO layer number supported by the mobile phone 100 may be the same granularity, that is, the first MIMO layer number supported by the mobile phone 100 is the first MIMO layer number supported by the mobile phone 100 on each frequency band, and the SRS antenna conversion capability supported by the mobile phone 100 is the SRS antenna conversion capability supported by the mobile phone 100 on each frequency band.
For example, the first MIMO layer number supported by the handset 100 may include: the handset 100 supports a maximum number of uplink MIMO layers and a maximum number of downlink MIMO layers on each frequency band in each frequency band combination supported by the handset 100. Accordingly, the second MIMO layer number may be an uplink MIMO layer number and/or a downlink MIMO layer number supported by the handset 100 on each frequency band in each frequency band combination supported by the handset 100.
In the above-described implementation (2), the mobile phone 100 discriminates between uplink and downlink and notifies the base station 200 of the first MIMO layer number. In example 2, assume that the handset 100 supports two band combinations: band combination 1 (including band 1 and band 3) and band combination 2 (including band 2 and band 4). Taking band 1 in band combination 1 as an example, the maximum uplink MIMO layer number supported by the mobile phone 100 on band 1 is 2, and the maximum downlink MIMO layer number is 8.
Correspondingly, the second MIMO layer number supported by the handset 100 in the frequency band 1 is uplink MIMO layer numbers 1 and 2, and downlink MIMO layer numbers 1,2,4 and 8.
Exemplary SRS antenna switching capabilities supported by handset 100 include: SRS antenna switching capability supported by the handset 100 on each frequency band in each frequency band combination supported by the handset 100. Specifically, the retrospective SRS antenna conversion capability supported by the mobile phone 100 is described in three cases below.
Case (I): the retrogressive SRS antenna switching capability supported by the mobile phone 100 includes: the mobile phone 100 supports the retractable SRS antenna switching capability on each frequency band in each frequency band combination supported by the mobile phone 100.
Wherein the retractable SRS antenna switching capability corresponds to the second MIMO layer number supported by the mobile phone 100 on the corresponding frequency band in the corresponding frequency band combination.
Taking the example 2 as an example: the retrogressive SRS antenna switching capability supported by the mobile phone 100 includes: the retrogressive SRS antenna conversion capability respectively supported by the mobile phone 100 in the frequency band 1, the frequency band 2, the frequency band 3 and the frequency band 4 is suitable for all uplink MIMO layers and all downlink MIMO layers supported by the mobile phone 100 in the corresponding frequency band.
Taking the example of the backspacing SRS antenna switching capability supported by the mobile phone 100 on the frequency band 1 of the frequency band combination 1, the backspacing SRS antenna switching capability corresponds to all uplink MIMO layers (including 1 and 2) and all downlink MIMO layers (including 1,2,4 and 8) supported by the mobile phone 100 on the frequency band 1, for example, the backspacing SRS antenna switching capability is applicable to the uplink MIMO layer 1 and also applicable to the downlink MIMO layer 1.
Case (II): the retrogressive SRS antenna switching capability supported by the mobile phone 100 includes: the mobile phone 100 supports a first retractable SRS antenna switching capability and a second retractable SRS antenna switching capability on each frequency band in each frequency band combination supported by the mobile phone 100.
The first retrogressive SRS antenna conversion capability corresponds to an uplink MIMO layer number in a second MIMO layer number supported by the mobile phone 100 on a corresponding frequency band in the corresponding frequency band combination, and the second retrogressive SRS antenna conversion capability corresponds to a downlink MIMO layer number in the second MIMO layer number supported by the mobile phone 100 on a corresponding frequency band in the corresponding frequency band combination.
Taking the example 2 as an example: the retrogressive SRS antenna switching capability supported by the mobile phone 100 includes: the mobile phone 100 supports the first and second retractable SRS antenna conversion capabilities on the frequency band 1, the frequency band 2, the frequency band 3, and the frequency band 4, respectively.
Taking the example of the backspacing SRS antenna switching capability supported by the mobile phone 100 on the frequency band 1 of the frequency band combination 1, the backspacing SRS antenna switching capability includes two backspacing SRS antenna switching capabilities; one of which corresponds to all uplink MIMO layers (including 1 and 2) supported by handset 100 over band 1 and the other corresponds to all downlink MIMO layers (including 1,2,4 and 8) supported by handset 100 over band 1.
Case (III): the retrogressive SRS antenna switching capability supported by the mobile phone 100 includes: the handset 100 supports a first set of retractable SRS antenna switching capabilities and a second set of retractable SRS antenna switching capabilities on each frequency band in each frequency band combination supported by the handset 100.
Wherein each of the first set of the SRS antenna switching capabilities corresponds to one uplink MIMO layer number of the second MIMO layer numbers supported by the mobile phone 100 on the corresponding frequency band in the corresponding frequency band combination, and each of the SRS antenna switching capabilities corresponds to one downlink MIMO layer number of the second MIMO layer numbers supported by the mobile phone 100 on the corresponding frequency band in the corresponding frequency band combination.
Taking the example 2 as an example: the retrogressive SRS antenna switching capability supported by the mobile phone 100 includes: the mobile phone 100 supports a first set of retractable SRS antenna switching capability and a second set of retractable SRS antenna switching capability on band 1, band 2, band 3, and band 4, respectively.
Taking the example of the backspacing SRS antenna switching capability supported by the mobile phone 100 on the frequency band 1 of the frequency band combination 1, the backspacing SRS antenna switching capability includes two sets of backspacing SRS antenna switching capability; one group of the SRS antenna conversion capabilities comprises SRS antenna conversion capabilities respectively corresponding to uplink MIMO layers 1 and 2 supported by the mobile phone 100 in the frequency band 1, and the other group of the SRS antenna conversion capabilities respectively corresponding to downlink MIMO layers 1,2,4 and 8 supported by the mobile phone 100 in the frequency band 1.
In one possible implementation, the use of the retrogressive SRS antenna switching capability supported by the mobile phone 100 for the base station 200 to reconfigure the SRS resources for antenna port switching for the mobile phone 100 is triggered by the following events: the base station 200 receives the second message sent by the handset 100.
The second message may include the MIMO layer number desired to be configured by the base station 200 for the handset 100 or the maximum MIMO layer number desired to be configured by the handset 100.
In one possible implementation, the second message is an assistance information message.
For example, when the mobile phone 100 is overheated, an auxiliary information message may be sent to the base station 200, where the auxiliary information message may include overheat related auxiliary information, so that the base station 200 can reduce the antenna port configuration for the base station to solve the overheat problem.
In one possible implementation, the first message is a user equipment capability message.
For example: after the mobile phone 100 accesses the network, or when the mobile phone 100 has a need to know its wireless capability at the base station 200, its wireless capability (radio capability) can be reported to the base station 200 through a user equipment capability message.
In the second embodiment, the difference from embodiment 1 is that: the number of MIMO layers in embodiment 2 may be the number of antenna ports. Namely: the first MIMO layer number in example 1 is replaced with the first antenna port number. Correspondingly, the second MIMO layer number in embodiment 1 is replaced by the second antenna port number.
Wherein the second antenna port number is less than or equal to the first antenna port number. The retractable SRS antenna switching capability corresponds to the second number of antenna ports.
The first antenna port number is used to identify a maximum number of antenna ports that the mobile phone 100 can support, including a maximum number of uplink antenna ports and a maximum number of downlink antenna ports that the mobile phone 100 supports on each carrier on each frequency band in each frequency band combination supported by the mobile phone. Correspondingly, the second antenna port number includes the uplink antenna port number and the maximum antenna port number supported by the mobile phone 100 on each carrier on each frequency band in each frequency band combination supported by the mobile phone.
Alternatively, the first antenna port number may further include: the handset 100 has a maximum number of uplink antenna ports and a maximum number of downlink antenna ports supported on each frequency band in each frequency band combination that the handset 100 supports. Correspondingly, the second antenna port number includes the uplink antenna port number and the maximum antenna port number supported by the mobile phone 100 on each frequency band in each frequency band combination supported by the mobile phone.
Likewise, possible implementations of SRS antenna conversion capability supported by the handset 100 may refer to the description in the first embodiment; for a different number of first antenna ports, several possible implementations of the retrogressive SRS antenna switching capability supported by the handset 100 may also refer to the description in the first embodiment.
It should be noted that the first embodiment and the second embodiment described above are merely exemplary of two possible implementations of the method for reporting the capability of the present application. In fact, the first number of antenna ports may also be used to identify the number of antenna ports that the handset 100 can support; alternatively, the first MIMO layer number may also be used to identify the number of MIMO layers that the handset 100 can support. Reference may also be made to the description of the first and second embodiments for specific implementations.
In a third embodiment, as shown in fig. 3, the method may include: the handset 100 sends a second message to the base station 200, where the second message includes a third MIMO layer number, where the third MIMO layer number is the maximum MIMO layer number that the handset 100 expects the base station 200 to configure for the handset 100.
Wherein the second message further includes a retrogressive SRS antenna switching capability supported by the mobile phone 100; the backspacing SRS antenna switching capability corresponds to a fourth MIMO layer number, where the fourth MIMO layer number is less than or equal to the third MIMO layer number. As shown in fig. 3, when configuring/reconfiguring the MIMO layer number for the mobile phone 100, the base station 200 may refer to the backspacing SRS antenna switching capability supported by the mobile phone 100 in the second message and the maximum MIMO layer number that the mobile phone 100 expects the base station 200 to configure for the mobile phone 100 configures the MIMO layer number for the mobile phone 100 and the corresponding SRS resource configured for antenna port switching.
The mobile phone 100 reports the maximum MIMO layer number expected to be configured by the base station 200 for the mobile phone 100 and the backspacing SRS antenna switching capability supported by the mobile phone 100 to the base station 200 through the second message, so that when the base station 200 reconfigures the MIMO layer number for the mobile phone 100, the SRS resource for antenna port switching can be reconfigured for the mobile phone 100 according to the maximum MIMO layer number expected to be configured by the base station 200 for the mobile phone 100 by the mobile phone 100 and the backspacing SRS antenna switching capability supported by the mobile phone 100.
For example, the mobile phone 100 may send the second message to the base station 200 when the heat (70 °) of the mobile phone 100 is higher than a preset threshold (the preset threshold is 50 °).
In this embodiment, the manner of carrying the maximum MIMO layer number configured by the base station 200 for the mobile phone 100 in the second message may at least include the following two implementation manners:
implementation mode (1): the maximum MIMO layer number configured by the mobile phone 100 with the base station 200 expected to be the mobile phone 100 is not only the maximum MIMO layer number applicable to uplink configured by the mobile phone 100 with the base station 200 expected to be the mobile phone 100, but also the maximum MIMO layer number applicable to downlink configured by the mobile phone 100 with the base station 200 expected to be the mobile phone 100.
For example, if the maximum MIMO layer number (the third MIMO layer number) of the mobile phone 100 that the base station 200 is expected to configure for the mobile phone 100 is 4, the base station 200 may determine that the uplink maximum MIMO layer number and the downlink maximum MIMO layer number of the mobile phone 100 that the base station 200 is expected to configure for the mobile phone 100 are both 4.
In implementation (1), in combination with the above example, the fourth MIMO layer number may be less than or equal to the third MIMO layer number, and the MIMO layer number supported by the handset 100. For example, if the number of MIMO layers supported by the handset 100 includes 1,2, and 4; then the fourth MIMO layer number may be any of the MIMO layer numbers 1,2, 4. The fourth MIMO layer number is applicable to both uplink and downlink.
Implementation mode (2): the maximum MIMO layer number that the handset 100 expects the base station 200 to configure for the handset 100 may include: the handset 100 expects the uplink maximum MIMO layer number (e.g., 2) configured by the base station 200 for the handset 100 and the downlink maximum MIMO layer number (e.g., 4) configured by the base station 200 for the handset 100.
In implementation (2), in combination with the above example, the fourth MIMO layer number of the uplink may be less than or equal to the third MIMO layer number of the uplink, and the MIMO layer number supported by the handset 100. For example, if the base station 200 is expected to configure the mobile phone 100 with 2 maximum uplink MIMO layers; then the fourth MIMO layer number of the uplink may be 1 or 2. The fourth MIMO layer number in the downlink may be less than or equal to the third MIMO layer number in the downlink, and the MIMO layer number supported by the handset 100. For example, if the base station 200 is expected to configure a downlink maximum MIMO layer number of 4 for the mobile phone 100; the fourth MIMO layer number of the uplink may be 1,2 or 4.
The backspacing SRS antenna conversion capability supported by the mobile phone 100 corresponds to the second MIMO layer number, which may specifically be: the retractable SRS antenna switching capability supported by the handset 100 corresponds to at least one fourth MIMO layer number.
In one possible implementation, the third MIMO layer number may be applicable to all frequency points that the handset 100 can use; alternatively, the frequency ranges may be divided into N frequency ranges according to a certain division rule.
Wherein N is an integer, N is greater than or equal to 2, and the third MIMO layer number may include a maximum MIMO layer number applicable to the ith frequency range for which the mobile phone 100 expects the base station 200 to configure, where i is an integer, and i is less than or equal to N.
For example, the partitioning rule is: the frequency band usable by the handset 100 is divided into two frequency ranges, including a first frequency range and a second frequency range, bounded by 6 GHz.
In the above-described implementation (2), the mobile phone 100 discriminates between uplink and downlink and notifies the base station 200 of the third MIMO layer number. In example 3, assume that the handset 100 supports a first frequency range and a second frequency range. Wherein, the maximum uplink MIMO layer number supported by the mobile phone 100 on the first frequency range is 2, and the maximum downlink MIMO layer number is 4; the maximum uplink MIMO layer number supported by the handset 100 in the second frequency range is 2 and the maximum downlink MIMO layer number is 4.
Correspondingly, the fourth MIMO layer number supported by the mobile phone 100 in the first frequency range includes uplink fourth MIMO layer numbers 1 and 2, and downlink fourth MIMO layer numbers 1,2 and 4; the fourth MIMO layer number supported by the handset 100 over the second frequency range includes uplink fourth MIMO layer numbers 1 and 2 and downlink fourth MIMO layer numbers 1,2 and 4.
In one implementation, the maximum MIMO layer number that the handset 100 expects the base station 200 to configure for the handset 100 may be the maximum MIMO layer number that the handset 100 expects the base station 200 to configure for the handset 100 on each frequency range.
Illustratively, the third MIMO layer number may include: the handset 100 expects the base station 200 to configure the maximum uplink MIMO layer number and the maximum downlink MIMO layer number for the serving cell over the first frequency range for the handset 100. Correspondingly, the fourth MIMO layer number is an uplink MIMO layer number and/or a downlink MIMO layer number, which are supported by the handset 100 in the first frequency range and are smaller than or equal to the third MIMO layer number. And/or the number of the groups of groups,
the third MIMO layer number may include: the handset 100 expects the base station 200 to configure the maximum uplink MIMO layer number and the maximum downlink MIMO layer number for the serving cell on the second frequency range for the handset 100. Correspondingly, the fourth MIMO layer number is an uplink MIMO layer number and/or a downlink MIMO layer number, which are supported by the handset 100 in the second frequency range and are smaller than or equal to the third MIMO layer number.
In one implementation, the granularity of the retractable SRS antenna conversion capability supported by the mobile phone 100 may be the same as the granularity of the maximum MIMO layer number that the mobile phone 100 expects the base station 200 to configure for the mobile phone 100, i.e., the retractable SRS antenna conversion capability supported by the mobile phone 100 is the SRS antenna conversion capability of the mobile phone 100 over each frequency range. Specifically, the backspacing SRS antenna switching capability supported by the mobile phone 100 is described in five cases below.

Wherein each of the retractable SRS antenna switching capabilities corresponds to a type of MIMO layer number in the first frequency range/the second frequency range.
Taking the backspacing SRS antenna switching capability supported by the mobile phone 100 in the first frequency range as an example, each backspacing SRS antenna switching capability corresponds to MIMO layer number 1,2, and 4, respectively, and is applicable to uplink and downlink, for example, the backspacing SRS antenna switching capability corresponding to MIMO layer number 1 is applicable to uplink MIMO layer number 1 and downlink MIMO layer number 1.
Case (4): the retrogressive SRS antenna conversion capability supported by the mobile phone 100 includes: a first retractable SRS antenna switching capability and a second retractable SRS antenna switching capability supported by the handset 100 in a first frequency range.
The first retrogressive SRS antenna conversion capability corresponds to an uplink MIMO layer number in all fourth MIMO layers supported by the mobile phone 100 in the first frequency range, and the second retrogressive SRS antenna conversion capability corresponds to a downlink MIMO layer number in all fourth MIMO layers supported by the mobile phone 100 in the first frequency range. And/or the number of the groups of groups,
The retrogressive SRS antenna switching capability supported by the mobile phone 100 includes: the handset 100 supports a first retractable SRS antenna switching capability and a second retractable SRS antenna switching capability in a second frequency range.
The first retrogressive SRS antenna conversion capability corresponds to an uplink MIMO layer number in all fourth MIMO layers supported by the mobile phone 100 in the second frequency range, and the second retrogressive SRS antenna conversion capability corresponds to a downlink MIMO layer number in all fourth MIMO layers supported by the mobile phone 100 in the second frequency range.
Taking the above example 3 as an example: the retrogressive SRS antenna switching capability supported by the mobile phone 100 includes: the handset 100 supports a first and second retractable SRS antenna switching capability in a first and second frequency range, respectively. The first retractable SRS antenna conversion capability corresponds to all uplink fourth MIMO layers supported by the mobile phone 100 in the first frequency range/the second frequency range, and the second retractable SRS antenna conversion capability corresponds to all downlink fourth MIMO layers supported by the mobile phone 100 in the first frequency range/the second frequency range.

Case (5): the retrogressive SRS antenna switching capability supported by the mobile phone 100 includes: a first set of retractable SRS antenna switching capabilities and a second set of retractable SRS antenna switching capabilities supported by the handset 100 in a first frequency range.
Wherein each of the first set of SRS antenna switching capabilities corresponds to one uplink MIMO layer of the fourth MIMO layer supported by the mobile phone 100 in the first frequency range, and each of the second set of SRS antenna switching capabilities corresponds to one downlink MIMO layer of the fourth MIMO layer supported by the mobile phone 100 in the first frequency range. And/or the number of the groups of groups,
the retrogressive SRS antenna switching capability supported by the mobile phone 100 includes: the handset 100 supports a first set of retractable SRS antenna switching capabilities and a second set of retractable SRS antenna switching capabilities in a second frequency range.
Wherein each of the first set of SRS antenna switching capabilities corresponds to one uplink MIMO layer of the fourth MIMO layer supported by the mobile phone 100 in the second frequency range, and each of the second set of SRS antenna switching capabilities corresponds to one downlink MIMO layer of the fourth MIMO layer supported by the mobile phone 100 in the second frequency range.
Taking the above example 3 as an example: the retrogressive SRS antenna switching capability supported by the mobile phone 100 includes: the handset 100 supports a first set of retractable SRS antenna switching capabilities and a second set of retractable SRS antenna switching capabilities in a first frequency range and a second frequency range, respectively. The first set of retrogressive SRS antenna conversion capability includes SRS antenna conversion capability corresponding to all uplink fourth MIMO layers supported by the mobile phone 100 in the first frequency range/the second frequency range, and the second set of retrogressive SRS antenna conversion capability includes SRS antenna conversion capability corresponding to all downlink fourth MIMO layers supported by the mobile phone 100 in the first frequency range/the second frequency range.

In one possible implementation, the second message is sent by the handset 100 to the base station 200 when it is overheated or when it is desired to reduce power.
In one possible implementation, the second message is an assistance information message. For example, when the mobile phone 100 is overheated, an auxiliary information message may be sent to the base station 200, where the auxiliary information message may include overheat related auxiliary information, so that the base station 200 can reduce configuration for the base station to solve the overheat problem.
In the fourth embodiment, the difference from the third embodiment is that: the number of MIMO layers in the fourth embodiment may be the number of antenna ports. Namely: the second message includes a third number of antenna ports. Correspondingly, the fourth antenna port number is less than or equal to the third antenna port number. The retractable SRS antenna switching capability corresponds to the fourth number of antenna ports.
The third antenna port number is used to identify a maximum antenna port number configured for the mobile phone 100 by the base station 200, including a maximum uplink antenna port number and a maximum downlink antenna port number supported by the mobile phone 100 in each frequency range. Accordingly, the fourth antenna port number includes the uplink antenna port number and the downlink antenna port number supported by the mobile phone 100 in each frequency range.
Likewise, reference may be made to the description in the third embodiment for several possible implementations of the retrogressive SRS antenna switching capability supported by the handset 100.
In the fifth embodiment, the difference from the third embodiment is that: the third MIMO layer number in the fifth embodiment may be the MIMO layer number that the handset 100 expects the base station 200 to configure for the handset 100. For example, the mobile phone 100 expects that the number of MIMO layers configured by the base station 200 for the mobile phone 100 is 4, and is suitable for uplink and downlink; also for example: the handset 100 expects that the MIMO layer number configured by the base station 200 for the handset 100 includes an uplink MIMO layer number 4 and a downlink MIMO layer number 4. The fourth MIMO layer number is less than or equal to the third MIMO layer number. The retractable SRS antenna switching capability supported by the handset 100 corresponds to the fourth MIMO layer number.
