Detailed Description
The embodiment of the application provides a method for reporting capacity, 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 the corresponding SRS resource when the network device configures the MIMO layer number or the antenna port number for the UE. When configuring the MIMO layer number or the antenna port number for the UE, the network device does not know the SRS antenna conversion capability corresponding to the capability that the configured MIMO layer number or the antenna port number can support, and therefore does not configure the SRS resource supporting the SRS antenna conversion capability corresponding to the SRS antenna conversion capability for the UE.
For example: when the UE has overheating problems, the UE requests the network equipment to reduce the MIMO layer number of the UE so as to relieve the overheating problems. After the network device lowers 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 equipment reduces the maximum downlink MIMO layer number of the UE, the UE closes the corresponding radio frequency receiving link. However, if the network device does not reallocate the SRS resource for user antenna port conversion, after the UE closes the corresponding radio frequency transmission link, the UE may not support antenna transmission under normal capability, thereby causing waste of some SRS resources; after the UE closes the corresponding radio frequency receiving link, if the UE still transmits the SRS according to the antenna with normal capability, the channel quality estimated by the network device according to the SRS may be inconsistent with the channel quality of the PDSCH transmission scheduled by the network device.
The method and the device aim to report the retroversion SRS antenna switching capability supported by the UE to the network equipment so that the network equipment can configure the corresponding SRS resource according to the retroversion SRS antenna switching capability reported by the UE.
The method of the embodiment of the application can be applied to a third Generation (3rd-Generation, 3G) mobile communication network, a fourth Generation (4th-Generation, 3G) mobile communication network Long Term Evolution (LTE) network, and a fifth Generation (5th-Generation, 5G) mobile communication system New Radio (NR) network. The method may also be applied to the next generation cellular mobile communication system and other subsequent 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. For example, a macro base station, a micro base station, or a distributed unit-control unit (DU-CU) or the like. A DU-CU is a device deployed in a radio access network and capable of wireless communication with user equipment. The base station can be used for configuring the number of MIMO layers or the number of antenna ports for the UE, or configuring SRS resources for SRS antenna port conversion for the UE.
The base station may be an evolved Node B (eNB) or e-NodeB in LTE, or may be a gNB in NR, for example. The base station may also be a wireless controller in a 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 Public Land Mobile Network (PLMN) network for future evolution, and the like, which is not limited in the embodiment of the present application.
The UE in the method of the embodiment of the present application may be a smart phone, a tablet Computer, a smart tv box, or other desktop, laptop, and handheld devices, such as an Ultra-mobile Personal Computer (UMPC), a netbook, a Personal Digital Assistant (PDA), a Portable Multimedia Player (PMP), a dedicated media Player, a consumer electronics device, a wearable device, an AR (augmented reality)/VR (virtual reality) device, and the like, which is not limited in the embodiment of the present application.
For example, the method of the embodiment of the present application may be applied to a process in which the network device actively configures the SRS resource for the UE. After the UE first accesses the network device, the network device may actively configure SRS resources for SRS antenna port conversion for the UE. For another example, the method of the embodiment of the present application may be applied to a process in which a network device configures an SRS resource for a UE in response to a request of the UE. The UE may request the network device to reconfigure the MIMO layer number or the antenna port number and the corresponding reconfigured SRS resource for the UE when the load is too large and the power is insufficient or the UE desires to reduce the power for various reasons. In the embodiment of the present application, the condition or the opportunity for triggering the network device to configure the SRS resource for the UE is not limited.
Fig. 1A is a schematic diagram of a possible application scenario provided by the present application. The UE (e.g., the cell phone 100) may actively request a 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/the antenna port number of the mobile phone 100, so as to reduce the subsequent power of the mobile phone 100 during transmission and reception and save the power.
It should be noted that fig. 1A only uses the user equipment as the handset 100 and the network equipment as the base station 200 as an example to describe the usage scenario of the embodiment of the present application, 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 listed above.

For example, when a photo is taken, the shutter is opened, light is transmitted to the camera photosensitive element through the lens, the optical signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing and converting into an image visible to naked eyes. The ISP can also carry out algorithm optimization on the noise, brightness and skin color of the image.

The photosensitive element may be a Charge Coupled Device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The light sensing element converts the optical signal into an electrical signal, which is then passed to the ISP where it is converted into a digital image signal. And the ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into image signal in standard RGB, YUV and other formats. In some embodiments, the handset 100 may include 1 or N cameras 193, N being a positive integer greater than 1.

The method for reporting capability provided by the embodiment of the present application is specifically described below with reference to fig. 1A and fig. 1B, and the basic principle of the method is as follows: the UE reports the supported retroversion SRS antenna switching capability to the network equipment, so that the network equipment correspondingly reconfigures SRS resources for the UE when the network equipment needs to reconfigure the number of MIMO layers or the number of antenna ports for the UE.
It should be noted that, in the following embodiments, the user equipment is taken as the mobile phone 100, and the network equipment is taken as the base station 200 as an example, and in fact, for any kind of user equipment UE, including several UEs listed above, the capability may be reported to the network equipment in the same manner and method.
The embodiment of the application provides a method for reporting capacity.
In a first embodiment, as shown in fig. 2, the method may comprise: 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 the fallback SRS antenna switching capability supported by the handset 100.
The mobile phone 100 reports the SRS antenna conversion capability supported by the mobile phone 100 and the retractable SRS antenna conversion capability supported by the mobile phone 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 retractable SRS antenna conversion capability supported by the mobile phone 100.
For example, the handset 100 may send the first message to the base station 200 when the remaining power (30%) of the handset 100 is lower than a preset threshold (35% of the preset threshold), or the handset 100 is powered on for the first time.
As shown in fig. 2, when configuring/reconfiguring MIMO layer numbers for the handset 100, the base station 200 may refer to the retractable SRS antenna conversion capability supported by the handset 100 in the first message to configure SRS resources for antenna port conversion corresponding to the handset 100.
In a possible implementation manner, the backspacing SRS antenna switching capability is determined and reported by the mobile phone 100 according to the hardware implementation and/or the current SRS resource configuration. For example, the current SRS antenna switching capability of the handset 100 is configured as 2T4R, that is, the handset 100 can transmit SRS on 2 antenna ports through 4 antennas; accordingly, the retractable SRS antenna switching capability supported by the handset 100 may be 1T4R and/or 1T2R, that is, the SRS antenna switching capability of the handset 100 is to transmit SRS on 1 antenna port through 4 antennas and/or the SRS antenna switching capability of the handset 100 is to transmit SRS on 1 antenna port through 2 antennas.
In another possible implementation manner, the first message may further include a first MIMO layer number supported by the handset 100; the retrogradable SRS antenna switching capability corresponds to the second MIMO layer number. The number of second MIMO layers is less than or equal to the number of first MIMO layers.
In this embodiment of the application, the manner in which the first message carries the number of first MIMO layers supported by the mobile phone 100 at least includes the following two implementation manners:
implementation (1): the first MIMO layer number supported by the handset 100 is used to identify the maximum MIMO layer number that can be supported 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 number of the first MIMO layers is 8, the base station 200 may determine that the maximum uplink MIMO layers and the maximum downlink MIMO layers supported by the mobile phone 100 are both 8.
In implementation (1), in combination with the above example, the number of second MIMO layers may be less than or equal to the number of first MIMO layers, and the number of MIMO layers supported by the mobile phone 100. For example, if the number of MIMO layers supported by the handset 100 includes 1, 2, 4, 8; then the second MIMO layer number may be any of 1, 2, 4, 8. The second MIMO layer number is applicable for uplink and downlink.
Implementation (2): the first MIMO layer number supported by the handset 100 may include: the maximum number of uplink MIMO layers supported by the mobile phone 100 and the maximum number of downlink MIMO layers supported by the mobile phone 100.
For example: the maximum number of uplink MIMO layers supported by the mobile phone 100 is 4, and the maximum number of downlink MIMO layers supported by the mobile phone 100 is 8. Then, the first MIMO layer number may include: the maximum number of uplink MIMO layers supported by the cell phone 100 is 4, and the maximum number of downlink MIMO layers supported by the cell phone 100 is 8.
In implementation (2), in combination with the above example, the number of second MIMO layers in the uplink may be less than or equal to the number of first MIMO layers in the uplink, and the number of MIMO layers supported by the mobile phone 100. For example, if the number of uplink MIMO layers supported by the mobile phone 100 includes 1, 2, 4; then the number of second MIMO layers in the uplink may be 1, 2 or 4. The downlink second MIMO layer number may be smaller than or equal to the downlink first MIMO layer number and the number of MIMO layers supported by the mobile phone 100. For example, if the number of downlink MIMO layers supported by the cell phone 100 includes 1, 2, 4, 8; then the second MIMO layer number for the downlink may be any of 1, 2, 4 or 8.
The retractable SRS antenna conversion capability supported by the mobile phone 100 corresponds to the number of the second MIMO layers, which may specifically be: the fallback-able 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 frequency band combination, each frequency band combination includes a plurality of frequency bands, for example, the handset 100 may support a frequency band combination 1, where the frequency band combination 1 is a combination of a frequency band 1 (for example, the frequency band 1 is 1800Mhz to 1810Mhz) and a frequency band 2 (for example, the frequency band 2 is 1820Mhz to 1830 Mhz). Each frequency band includes multiple carriers. The handset 100 may support some of the multiple carriers described above.
Based on this, in the first scenario, the number of MIMO layers supported by the handset 100 may include: the maximum number of uplink MIMO layers and the maximum number of downlink MIMO layers supported by the cell phone 100 on each carrier on each frequency band in each frequency band combination supported by the cell phone 100.
Accordingly, the second MIMO layer number may be: the number of uplink MIMO layers and/or the number of downlink MIMO layers supported by the cell phone 100 on each carrier on each frequency band in each frequency band combination supported by the cell phone 100.
In the above implementation (2), the mobile phone 100 notifies the base station 200 of the first MIMO layer number separately in the uplink and downlink. In example 1, assume that the handset 100 supports two frequency band combinations: band combination 1 (including band 1 and band 3) and band combination 2 (including band 2 and band 4). Taking frequency band 1 in frequency band combination 1 as an example, the handset 100 supports carrier 1 and carrier 2 on frequency band 1. The maximum number of uplink MIMO layers supported by the mobile phone 100 on the carrier 1 is 4, and the maximum number of downlink MIMO layers is 8. The maximum number of uplink MIMO layers supported by the mobile phone 100 on the carrier 2 is 2, and the maximum number of downlink MIMO layers is 4.
Correspondingly, the number of the second MIMO layers supported by the mobile phone 100 on the carrier 1 is 1, 2, and 4 for uplink MIMO layers, and 1, 2, 4, and 8 for downlink MIMO layers; the second MIMO layer number supported by the mobile phone 100 on the carrier 2 includes uplink MIMO layer numbers 1 and 2, and downlink MIMO layer numbers 2 and 4.
In a first scenario, the SRS antenna switching capability may be of a different granularity than the number of first MIMO layers supported by the handset 100. For example, the SRS antenna switching capability is the SRS antenna switching capability supported by the handset 100 in each frequency band.

Case (3): the fallback-able SRS antenna switching capability supported by the handset 100 includes: a first and a second fallback SRS antenna switching capability supported by the handset 100 on each frequency band in each combination of frequency bands supported by the handset 100.
The first fallback SRS antenna switching capability corresponds to all uplink MIMO layers in the second MIMO layers supported by the mobile phone 100 on the corresponding band in the corresponding band combination, and the second fallback SRS antenna switching capability corresponds to all downlink MIMO layers in the second MIMO layers supported by the mobile phone 100 on the corresponding band in the corresponding band combination.

The first retroversion SRS antenna conversion can correspond to all uplink MIMO layers on a corresponding frequency band, and the second retroversion SRS antenna conversion can correspond to all downlink MIMO layers on a corresponding frequency band, and is suitable for all carriers on the corresponding frequency band.
Taking the retractable SRS antenna switching capability supported by the handset 100 on the frequency band 1 of the frequency band combination 1 as an example, the SRS antenna switching capability includes two retractable SRS antenna switching capabilities. One of the uplink MIMO layers corresponds to all uplink MIMO layers (including 1, 2, and 4) supported by the mobile phone 100 on the carrier 1 and all uplink MIMO layers (including 1 and 2) supported by the mobile phone 100 on the carrier 2; another corresponds to all downlink MIMO layer numbers supported by the handset 100 on carrier 1 (including 1, 2, 4 and 8) and all downlink MIMO layer numbers supported by the handset 100 on carrier 2 (including 2 and 4).
Case (4): the fallback-able SRS antenna switching capability supported by the handset 100 includes: handset 100 supports at least one fallback SRS antenna switching capability on each frequency band in each combination of frequency bands supported by handset 100.
Wherein each of the fallback SRS antenna switching capabilities corresponds to a second number of MIMO layers supported by the handset 100 on a corresponding band of the corresponding band combination.
Taking example 1 above as an example: the fallback-able SRS antenna switching capability supported by the handset 100 includes: the mobile phone 100 supports at least one retractable SRS antenna conversion capability in the frequency band 1, the frequency band 2, the frequency band 3, and the frequency band 4, and is suitable for all carriers in the corresponding frequency band, and is also suitable for uplink and downlink on the corresponding carrier.
Taking the retractable SRS antenna switching capability supported by the handset 100 on frequency band 1 of frequency band combination 1 as an example, the retractable SRS antenna switching capability includes capability 1, capability 2, … …, and capability 5. Wherein. Capability 1 corresponds to MIMO layer number 1, capability 2 corresponds to MIMO layer number 2, capability 3 corresponds to MIMO layer number 4, and capability 4 corresponds to MIMO layer number 8. Wherein, capability 1, capability 2, … …, and capability 4 are applicable to both the corresponding uplink MIMO layer number and the corresponding downlink MIMO layer number supported on carrier 1 and carrier 2. For example: capability 1 applies to the number of uplink MIMO layers 1 and the number of downlink MIMO layers 1 supported on carrier 1 and carrier 2.
Case (5): the fallback-able SRS antenna switching capability supported by the handset 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 on each of the frequency bands in each of the combinations of frequency bands supported by the handset 100.

One of the sets includes capabilities corresponding to all uplink MIMO layers supported by the mobile phone 100 on the frequency band 1 (including capabilities corresponding to the uplink MIMO layers 1, 2, and 4 supported on the carrier 1, and capabilities corresponding to the uplink MIMO layers 1 and 2 supported on the carrier 2, respectively), and the other set includes capabilities corresponding to all downlink MIMO layers supported by the mobile phone 100 on the frequency band 1 (including capabilities corresponding to the downlink MIMO layers 1, 2, 4, and 8 supported on the carrier 1, and capabilities corresponding to the downlink MIMO layers 2 and 4 supported on the carrier 2, respectively).
In a second scenario, the SRS antenna switching capability may be the same granularity as the number of first MIMO layers supported by the handset 100. For example, the SRS antenna switching capability is the SRS antenna switching capability supported by the handset 100 on each carrier.
Specifically, the SRS antenna switching capability supported by the handset 100 includes: SRS antenna switching capability supported by the handset 100 on each carrier on each frequency band in each frequency band combination supported by the handset 100; the fallback-able SRS antenna switching capability supported by the handset 100 includes: the handset 100 supports a fallback SRS antenna switching capability on each carrier on each frequency band in each combination of frequency bands supported by the handset 100.

Taking the retractable SRS antenna switching capability supported by the handset 100 on the carrier 1 on the frequency band combination 1 as an example, the SRS antenna switching capability corresponds to all uplink MIMO layer numbers (including 1, 2 and 4) and downlink MIMO layer numbers (including 1, 2, 4 and 8) supported by the handset 100 on the carrier 1.
Case (ii): the fallback-able SRS antenna switching capability supported by the handset 100 includes: the handset 100 may support a first and a second retractable SRS antenna switching capability on each carrier on each frequency band in each combination of frequency bands supported by the handset 100.
Wherein the first fallback SRS antenna switching capability corresponds to an uplink MIMO layer number of the second MIMO layer numbers supported by the mobile phone 100 on the corresponding carrier on the corresponding frequency band in the corresponding frequency band combination, and the second fallback SRS antenna switching capability corresponds to a downlink MIMO layer number of the second MIMO layer numbers supported by the mobile phone 100 on the corresponding carrier on the corresponding frequency band in the corresponding frequency band combination.
Taking example 1 above as an example: the fallback-able SRS antenna switching capability supported by the handset 100 includes: the first and second fallback SRS antenna switching capabilities supported by the handset 100 on the carrier 1 and the carrier 2 respectively on the frequency band 1, and the first and second fallback SRS antenna switching capabilities supported by the handset 100 on each of the carriers on the frequency bands 2, 3, and 4 respectively.
Taking the retractable SRS antenna switching capability supported by the mobile phone 100 on the carrier 1 on the frequency band combination 1 as an example, the SRS antenna switching capability includes two retractable SRS antenna switching capabilities; one corresponding to all uplink MIMO layer numbers (1, including 2 and 4) supported by the mobile phone 100 on the carrier 1, and one corresponding to all downlink MIMO layer numbers (including 1, 2, 4 and 8) supported by the mobile phone 100 on the carrier 1 on the frequency band 1.
Case (iii): the fallback-able SRS antenna switching capability supported by the handset 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 combination of frequency bands supported by the handset 100.
Wherein each of the first set of retractable SRS antenna switching capabilities corresponds to one of the second MIMO layer numbers supported by the handset 100 on each carrier on the corresponding band in the corresponding band combination, and each of the second set of retractable SRS antenna switching capabilities corresponds to one of the second MIMO layer numbers supported by the handset 100 on each carrier on the corresponding band in the corresponding band combination.
Taking example 1 above as an example: the fallback-able SRS antenna switching capability supported by the handset 100 includes: the first set of retractable SRS antenna switching capabilities and the second set of retractable SRS antenna switching capabilities that are supported by the handset 100 on carrier 1 and carrier 2 respectively on frequency band 1, and the first set of retractable SRS antenna switching capabilities and the second set of retractable SRS antenna switching capabilities that are supported by the handset 100 on all carriers on frequency band 2, frequency band 3, and frequency band 4 respectively.
Taking the retractable SRS antenna switching capability supported by the mobile phone 100 on the carrier 1 on the frequency band 1 of the frequency band combination 1 as an example, the SRS antenna switching capability includes two sets of SRS antenna switching capabilities; one of the groups includes SRS antenna capabilities corresponding to uplink MIMO layer numbers 1, 2, 4, and 8 supported by the mobile phone 100 on the carrier 1, and the other group includes SRS antenna conversion capabilities corresponding to downlink MIMO layer numbers 1, 2, 4, and 8 supported by the mobile phone 100 on the carrier 1.
In a third scenario, the SRS antenna conversion capability supported by the cell phone 100 and the first MIMO layer number supported by the cell phone 100 may be of the same granularity, that is, the first MIMO layer number supported by the cell phone 100 is the first MIMO layer number supported by the cell phone 100 on each frequency band, and the SRS antenna conversion capability supported by the cell phone 100 is the SRS antenna conversion capability supported by the cell phone 100 on each frequency band.
Illustratively, the first MIMO layer number supported by the handset 100 may include: the maximum number of uplink MIMO layers and the maximum number of downlink MIMO layers supported by the cell phone 100 on each frequency band in each frequency band combination supported by the cell phone 100. Accordingly, the second MIMO layer number may be an uplink MIMO layer number and/or a downlink MIMO layer number supported by the mobile phone 100 on each frequency band in each frequency band combination supported by the mobile phone 100.
In the above implementation (2), the mobile phone 100 notifies the base station 200 of the first MIMO layer number separately in the uplink and downlink. In example 2, assume that the handset 100 supports two frequency band combinations: band combination 1 (including band 1 and band 3) and band combination 2 (including band 2 and band 4). Taking the frequency band 1 in the frequency band combination 1 as an example, the maximum uplink MIMO layer number supported by the mobile phone 100 on the frequency band 1 is 2, and the maximum downlink MIMO layer number is 8.
Accordingly, the second MIMO layers supported by the mobile phone 100 on the frequency band 1 are uplink MIMO layers 1 and 2, and downlink MIMO layers 1, 2, 4, and 8.
Exemplary SRS antenna switching capabilities supported by the handset 100 include: the handset 100 supports SRS antenna switching capability on each frequency band in each combination of frequency bands supported by the handset 100. Specifically, the retractable SRS antenna switching capability supported by the handset 100 is described in three cases below.
Case (I): the fallback-able SRS antenna switching capability supported by the handset 100 includes: the handset 100 supports a fallback SRS antenna switching capability on each frequency band in each combination of frequency bands supported by the handset 100.
Wherein the fallback SRS antenna switching capability corresponds to the number of second MIMO layers supported by the handset 100 on the corresponding band in the corresponding band combination.
Taking the above example 2 as an example: the fallback-able SRS antenna switching capability supported by the handset 100 includes: the retractable SRS antenna conversion capability 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 applicable to all uplink MIMO layers and all downlink MIMO layers that can be supported by the mobile phone 100 in the corresponding frequency band.
Taking the retractable SRS antenna conversion capability supported by the handset 100 on the frequency band 1 of the frequency band combination 1 as an example, the retractable SRS antenna conversion capability corresponds to all uplink MIMO layer numbers (including 1 and 2) and all downlink MIMO layer numbers (including 1, 2, 4, and 8) supported by the handset 100 on the frequency band 1, for example, the retractable SRS antenna conversion capability is applicable to the uplink MIMO layer number 1 and also applicable to the downlink MIMO layer number 1.
Case (II): the fallback-able SRS antenna switching capability supported by the handset 100 includes: a first and a second fallback SRS antenna switching capability supported by the handset 100 on each frequency band in each combination of frequency bands supported by the handset 100.
The first fallback SRS antenna switching capability corresponds to an uplink MIMO layer number of a second MIMO layer number supported by the mobile phone 100 on a corresponding frequency band of the corresponding frequency band combination, and the second fallback SRS antenna switching capability corresponds to a downlink MIMO layer number of the second MIMO layer number supported by the mobile phone 100 on the corresponding frequency band of the corresponding frequency band combination.
Taking the above example 2 as an example: the fallback-able SRS antenna switching capability supported by the handset 100 includes: the mobile phone 100 supports a first retractable SRS antenna switching capability and a second retractable SRS antenna switching capability in band 1, band 2, band 3, and band 4, respectively.
Taking the retractable SRS antenna switching capability supported by the mobile phone 100 on the frequency band 1 of the frequency band combination 1 as an example, the retractable SRS antenna switching capability includes two retractable SRS antenna switching capabilities; one of the MIMO layers corresponds to all uplink MIMO layers (including 1 and 2) supported by the mobile phone 100 on the frequency band 1, and the other MIMO layer corresponds to all downlink MIMO layers (including 1, 2, 4, and 8) supported by the mobile phone 100 on the frequency band 1.
Case (III): the fallback-able SRS antenna switching capability supported by the handset 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 combination of frequency bands supported by the handset 100.
Wherein each of the first set of retractable SRS antenna switching capabilities corresponds to one of the second MIMO layer numbers supported by the handset 100 on a corresponding frequency band of the corresponding combination of frequency bands, and each of the second set of retractable SRS antenna switching capabilities corresponds to one of the second MIMO layer numbers supported by the handset 100 on a corresponding frequency band of the corresponding combination of frequency bands.
Taking the above example 2 as an example: the fallback-able SRS antenna switching capability supported by the handset 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 band 1, band 2, band 3, and band 4, respectively.
Taking the retractable SRS antenna switching capability supported by the mobile phone 100 on the frequency band 1 of the frequency band combination 1 as an example, the retractable SRS antenna switching capability includes two sets of retractable SRS antenna switching capabilities; one of the groups includes SRS antenna capabilities corresponding to uplink MIMO layer numbers 1 and 2 supported by the mobile phone 100 on the frequency band 1, and the other group includes SRS antenna conversion capabilities corresponding to downlink MIMO layer numbers 1, 2, 4 and 8 supported by the mobile phone 100 on the frequency band 1.
In one possible implementation, the fallback SRS antenna switching capability supported by the handset 100 is used for the base station 200 to reconfigure the SRS resource for antenna port switching for the handset 100, which 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 number of MIMO layers that the base station 200 desires to configure for the mobile phone 100 or the maximum number of MIMO layers that the base station 200 desires to configure.
In one possible implementation, the second message is an assistance information message.
For example, when the handset 100 is overheated, the handset 100 may send an auxiliary information message to the base station 200, where the auxiliary information message may include auxiliary information related to overheating, so that the base station 200 may reduce the antenna port configuration for the base station to solve the overheating problem.
In one possible implementation, the first message is a user equipment capability message.
For example: after the handset 100 accesses the network, or when the handset 100 needs to know the radio capability of the base station 200, the radio capability (radio capability) of the handset 100 can be reported to the base station 200 through the ue 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 is replaced with the first antenna port number in embodiment 1. Correspondingly, the second MIMO layer number in embodiment 1 is replaced with the second antenna port number.
And the number of the second antenna ports is less than or equal to the number of the first antenna ports. The retractable SRS antenna switching capability corresponds to the second number of antenna ports.
The first antenna port number is used to identify the maximum antenna port number that can be supported by the mobile phone 100, and includes the maximum uplink antenna port number and the maximum downlink antenna port number that are supported by the mobile phone 100 on each carrier on each frequency band in each frequency band combination that is supported by the mobile phone 100. Correspondingly, the second number of antenna ports includes the number of uplink antenna ports and the maximum number of antenna ports supported by the handset 100 on each carrier on each frequency band in each frequency band combination supported by the handset.
Alternatively, the first antenna port number may further include: the maximum number of uplink antenna ports and the maximum number of downlink antenna ports that the mobile phone 100 supports on each frequency band in each frequency band combination that the mobile phone 100 supports. Correspondingly, the second number of antenna ports includes the number of uplink antenna ports and the maximum number of antenna ports supported by the mobile phone 100 on each frequency band in each frequency band combination supported by the mobile phone.
Similarly, reference may be made to the description in the first embodiment for a possible implementation manner of the SRS antenna switching capability supported by the handset 100; for different numbers of first antenna ports, reference may also be made to the description in the first embodiment for several possible implementations of the retractable SRS antenna switching capability supported by the handset 100.
It should be noted that the first embodiment and the second embodiment described above are only used as examples to describe two possible implementation manners of the method for reporting 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 can be supported by the handset 100; alternatively, the first MIMO layer number may also be used to identify the MIMO layer numbers that may be supported by the handset 100. For specific implementation, reference may also be made to the descriptions in the first embodiment and the second embodiment.
In a third embodiment, as shown in fig. 3, the method may include: the mobile phone 100 sends a second message to the base station 200, where the second message includes a third MIMO layer number, and the third MIMO layer number is a maximum MIMO layer number that the mobile phone 100 expects the base station 200 to configure for the mobile phone 100.
Wherein the second message further includes the fallback SRS antenna switching capability supported by the handset 100; the retrogradable SRS antenna switching capability corresponds to a fourth MIMO layer number, wherein the fourth MIMO layer number is less than or equal to the third MIMO layer number. As shown in fig. 3, when configuring/reconfiguring MIMO layer numbers for the handset 100, the base station 200 may refer to the retrogradable SRS antenna conversion capability supported by the handset 100 in the second message and the maximum MIMO layer number that the handset 100 expects the base station 200 to configure for the handset 100, configure MIMO layer numbers for the handset 100 and correspondingly configure SRS resources for antenna port conversion.
The mobile phone 100 reports the maximum MIMO layer number that the base station 200 expects to configure for the mobile phone 100 and the retractable SRS antenna conversion 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 mobile phone 100 can reconfigure the SRS resource for antenna port conversion for the mobile phone 100 according to the maximum MIMO layer number that the base station 200 expects to configure for the mobile phone 100 by the mobile phone 100 and the retractable SRS antenna conversion capability supported by the mobile phone 100.
For example, the handset 100 may send the second message to the base station 200 when the heat (70 °) of the handset 100 is higher than a preset threshold (50 °).
In this embodiment of the application, the manner in which the second message carries the maximum MIMO layer number that the mobile phone 100 expects the base station 200 to configure for the mobile phone 100 may include at least the following two implementation manners:
implementation (1): the maximum number of MIMO layers that the mobile phone 100 expects the base station 200 to configure for the mobile phone 100 is both the maximum number of MIMO layers that the mobile phone 100 expects the base station 200 to configure for the mobile phone 100 and are suitable for uplink and the maximum number of MIMO layers that the mobile phone 100 expects the base station 200 to configure for the mobile phone 100 and are suitable for downlink.
For example, if the mobile phone 100 expects the base station 200 to configure the maximum MIMO layer number (the third MIMO layer number) for the mobile phone 100 to be 4, the base station 200 may determine that the mobile phone 100 expects the base station 200 to configure the mobile phone 100 with the maximum uplink MIMO layer number and the maximum downlink MIMO layer number both being 4.
In implementation (1), in combination with the above example, the number of the fourth MIMO layers may be less than or equal to the number of the third MIMO layers, and the number of MIMO layers supported by the mobile phone 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 1, 2, 4. The fourth MIMO layer number is applicable for uplink and downlink.
Implementation (2): the maximum number of MIMO layers that the handset 100 expects the base station 200 to configure for the handset 100 may include: the mobile phone 100 expects the maximum number of MIMO layers (e.g., 2) in uplink configured by the base station 200 for the mobile phone 100 and the maximum number of MIMO layers (e.g., 4) in downlink configured by the base station 200 for the mobile phone 100.
In implementation (2), in combination with the above example, the number of the fourth MIMO layers in the uplink may be less than or equal to the number of the third MIMO layers in the uplink, and the number of MIMO layers supported by the mobile phone 100. For example, if it is desired that the base station 200 configures the maximum number of uplink MIMO layers for the mobile phone 100 to be 2; then the fourth MIMO layer number for the uplink may be 1 or 2. The number of downlink fourth MIMO layers may be less than or equal to the number of downlink third MIMO layers and the number of MIMO layers supported by the mobile phone 100. For example, if it is desired that the base station 200 configures the mobile phone 100 with a maximum number of downlink MIMO layers of 4; then the fourth MIMO layer number for the uplink may be 1, 2 or 4.
The retractable SRS antenna conversion capability supported by the mobile phone 100 corresponds to the number of the second MIMO layers, which may specifically be: the fallback-able SRS antenna switching capability supported by the handset 100 corresponds to at least one fourth MIMO layer number.
In a possible implementation manner, the third MIMO layer number may be applicable to all frequency points available to the mobile phone 100; alternatively, the division into N frequency ranges may be performed according to a certain division rule.
Where N is an integer, N is greater than or equal to 2, and the third MIMO layer number may include the maximum MIMO layer number suitable for the ith frequency range and configured by the base station 200 expected by the mobile phone 100, 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 implementation (2), the mobile phone 100 notifies the base station 200 of the third MIMO layer number separately in the uplink and downlink. In example 3, it is assumed that the handset 100 supports a first frequency range and a second frequency range. The maximum uplink MIMO layer number supported by the mobile phone 100 in the first frequency range is 2, and the maximum downlink MIMO layer number is 4; the maximum number of uplink MIMO layers supported by the mobile phone 100 in the second frequency range is 2, and the maximum number of downlink MIMO layers is 4.
Correspondingly, the fourth MIMO layer number supported by the mobile phone 100 in the first frequency range includes the uplink fourth MIMO layer numbers 1 and 2, and the downlink fourth MIMO layer numbers 1, 2 and 4; the fourth MIMO layer numbers supported by the mobile phone 100 in the second frequency range include the uplink fourth MIMO layer numbers 1 and 2, and the downlink fourth MIMO layer numbers 1, 2, and 4.
In one implementation, the maximum number of MIMO layers that the handset 100 expects the base station 200 to configure for the handset 100 may be the maximum number of MIMO layers 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 mobile phone 100 expects the base station 200 to configure the mobile phone 100 with the maximum uplink MIMO layer number and the maximum downlink MIMO layer number of the serving cell in the first frequency range. Correspondingly, the number of the fourth MIMO layers is the number of uplink MIMO layers and/or the number of downlink MIMO layers supported by the mobile phone 100 in the first frequency range and is less than or equal to the number of the third MIMO layers. And/or the presence of a gas in the gas,
the third MIMO layer number may include: the mobile phone 100 expects the base station 200 to configure the mobile phone 100 with the maximum uplink MIMO layer number and the maximum downlink MIMO layer number of the serving cell in the second frequency range. Correspondingly, the number of the fourth MIMO layers is the number of uplink MIMO layers and/or the number of downlink MIMO layers supported by the mobile phone 100 in the second frequency range and is less than or equal to the number of the third MIMO layers.
In one implementation, the granularity of the retractable SRS antenna conversion capability supported by the handset 100 may be the same as the granularity of the maximum MIMO layer number that the handset 100 expects the base station 200 to configure for the handset 100, that is, the retractable SRS antenna conversion capability supported by the handset 100 is the SRS antenna conversion capability of the handset 100 in each frequency range. Specifically, the retractable SRS antenna switching capability supported by the handset 100 is described in five cases below.
The retractable SRS antenna switching capability supported by the handset 100 includes: the handset 100 supports at least one retractable SRS antenna switching capability in a first frequency range.
Wherein each of the fallback SRS antenna switching capabilities corresponds to a combination of one uplink MIMO layer number and one downlink MIMO layer number in the fourth MIMO layer numbers supported by the handset 100 in the first frequency range. And/or the presence of a gas in the gas,

Wherein each of the fallback SRS antenna switching capabilities corresponds to all fourth MIMO layers supported by the handset 100 in the second frequency range.
Taking example 3 above as an example: the fallback-able SRS antenna switching capability supported by the handset 100 includes: the mobile phone 100 supports the retractable SRS antenna switching capability in the first frequency range and the second frequency range, and is suitable for uplink and downlink.
Taking the retractable SRS antenna switching capability supported by the handset 100 in the first frequency range as an example, the retractable SRS antenna switching capability corresponds to all MIMO layer numbers supported by the handset 100 in the first frequency range, including uplink MIMO layer numbers (including 1 and 2) and downlink MIMO layer numbers (including 1, 2 and 4).
The method comprises the following steps: the fallback-able SRS antenna switching capability supported by the handset 100 includes: the handset 100 supports at least one retractable SRS antenna switching capability in a first frequency range.

Wherein each of the fallback SRS antenna switching capabilities corresponds to a MIMO layer number in the first frequency range/the second frequency range.
Taking the retractable SRS antenna conversion capability supported by the mobile phone 100 in the first frequency range as an example, each retractable SRS antenna conversion capability corresponds to MIMO layer numbers 1, 2, and 4, respectively, and is applicable to uplink and downlink, for example, the retractable SRS antenna conversion capability corresponding to MIMO layer number 1 is applicable to uplink MIMO layer number 1 and downlink MIMO layer number 1.
The method comprises the following steps: the fallback SRS antenna switching capability supported by the handset 100 includes: the handset 100 supports a first and a second retractable SRS antenna switching capability in a first frequency range.
Wherein the first fallback SRS antenna switching capability corresponds to the uplink MIMO layer number among all the fourth MIMO layer numbers supported by the handset 100 in the first frequency range, and the second fallback SRS antenna switching capability corresponds to the downlink MIMO layer number among all the fourth MIMO layer numbers supported by the handset 100 in the first frequency range. And/or the presence of a gas in the gas,
The fallback-able SRS antenna switching capability supported by the handset 100 includes: the handset 100 supports a first and a second retractable SRS antenna switching capability in a second frequency range.
Wherein the first fallback SRS antenna switching capability corresponds to the uplink MIMO layer number of all the fourth MIMO layer numbers supported by the handset 100 in the second frequency range, and the second fallback SRS antenna switching capability corresponds to the downlink MIMO layer number of all the fourth MIMO layer numbers supported by the handset 100 in the second frequency range.
Taking example 3 above as an example: the fallback-able SRS antenna switching capability supported by the handset 100 includes: the handset 100 supports a first and a second retractable SRS antenna switching capability in a first and a second frequency range, respectively. The first fallback SRS antenna switching 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 fallback SRS antenna switching capability corresponds to all downlink fourth MIMO layers supported by the mobile phone 100 in the first frequency range/the second frequency range.
Taking the retractable SRS antenna conversion capability supported by the mobile phone 100 in the first frequency range as an example, the first retractable SRS antenna conversion capability corresponds to the fourth MIMO layer numbers 1 and 2 in uplink, and the second retractable SRS antenna conversion capability corresponds to the fourth MIMO layer numbers 1, 2 and 4 in downlink.
Case three: the fallback-able SRS antenna switching capability supported by the handset 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.
Wherein each of the first set of retractable SRS antenna switching capabilities corresponds to one of the fourth MIMO layer numbers supported by the handset 100 in the first frequency range, and each of the second set of retractable SRS antenna switching capabilities corresponds to one of the fourth MIMO layer numbers supported by the handset 100 in the first frequency range. And/or the presence of a gas in the gas,
the fallback-able SRS antenna switching capability supported by the handset 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 retractable SRS antenna switching capabilities corresponds to one of the fourth MIMO layer numbers supported by the handset 100 in the second frequency range, and each of the second set of retractable SRS antenna switching capabilities corresponds to one of the fourth MIMO layer numbers supported by the handset 100 in the second frequency range.
Taking example 3 above as an example: the fallback-able SRS antenna switching capability supported by the handset 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 returnable SRS antenna conversion capabilities includes SRS antenna conversion capabilities 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 returnable SRS antenna conversion capabilities includes SRS antenna conversion capabilities corresponding to all downlink fourth MIMO layers supported by the mobile phone 100 in the first frequency range/the second frequency range.
Taking the retractable SRS antenna conversion capability supported by the mobile phone 100 in the first frequency range as an example, the first set of retractable SRS antenna conversion capability includes SRS antenna conversion capabilities corresponding to the fourth uplink MIMO layer number 1 and the MIMO layer number 2, respectively, and the first set of retractable SRS antenna conversion capability includes SRS antenna conversion capabilities corresponding to the fourth downlink MIMO layer number 1 and the fourth downlink MIMO layer number 4, respectively.
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 handset 100 is overheated, the handset 100 may send an auxiliary information message to the base station 200, where the auxiliary information message may include auxiliary information related to overheating, so that the base station 200 may reduce the configuration for the base station and solve the overheating 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 antenna port number. Correspondingly, the number of fourth antenna ports is less than or equal to the number of third antenna ports. 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 that the mobile phone 100 expects the base station 200 to configure for, including a maximum uplink antenna port number and a maximum downlink antenna port number that the mobile phone 100 supports in each frequency range. Correspondingly, the fourth number of antenna ports includes the number of uplink antenna ports and the number of downlink antenna ports supported by the mobile phone 100 in each frequency range.
Similarly, for several possible implementations of the retractable SRS antenna switching capability supported by the handset 100, reference may also be made to the description in the third embodiment.
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 mobile phone 100 expects the base station 200 to configure for the mobile phone 100. For example, the mobile phone 100 expects that the base station 200 configures 4 MIMO layers for the mobile phone 100, which is suitable for uplink and downlink; another example is: the mobile phone 100 expects the MIMO layer number configured by the base station 200 for the mobile phone 100 to include an uplink MIMO layer number of 4 and a downlink MIMO layer number of 4. The number of fourth MIMO layers is less than or equal to the number of third MIMO layers. The fallback-able SRS antenna switching capability supported by the handset 100 corresponds to the fourth MIMO layer number. That is, the handset 100 may expect the base station 200 to configure a MIMO layer number of 4 for it, but the base station 200 may configure any layer number less than or equal to the expected value, e.g., 1, 2, 4, for it according to the expected value.
The third MIMO layer number is used to identify the MIMO layer number that the mobile phone 100 expects the base station 200 to configure for, and includes the uplink MIMO layer number and the downlink MIMO layer number that the mobile phone 100 expects the base station 200 to configure for in each frequency range.

For example, the mobile phone 100 expects that the maximum uplink antenna port number configured by the base station 200 for the mobile phone 100 is 4 and the maximum downlink MIMO layer number is 6. The retractable SRS antenna conversion capability supported by the mobile phone 100 corresponds to the number of fourth antenna ports or the number of fourth MIMO layers, where the number of fourth antenna ports is less than or equal to the number of third antenna ports, and the number of fourth MIMO layers is less than or equal to the number of third MIMO layers.
