Method and device for optimizing power of terminal equipment
Technical Field
The present application relates to the field of communications, and more particularly, to a method and apparatus for power optimization of a terminal device, such as a terminal device, a chip, a computer storage medium, and so on.
Background
In a mobile communication system, when a terminal device (e.g., a User Equipment (UE)) communicates with a network device, the network device needs to know the capability of the UE in advance, and can configure the UE according to the maximum capability reported by the UE, thereby avoiding a situation where the communication capability exceeds the capability of the UE.
In the prior art, when a UE has an overheating problem, the UE may report a lower UE capability (e.g., a baseband capability or a multi-carrier capability of the UE) to a network device through Radio Resource Control (RRC) signaling. The network device may reconfigure the capability of the UE (for example, configure a lower transmission rate or configure a lower number of carriers) when receiving the lower UE capability, thereby reducing the power of the UE and further solving the problem of overheating of the UE. However, in the prior art, the UE reports a smaller capability to the network device only when the UE is overheated, so as to reduce the power of the UE.
Therefore, how to optimize the power of the terminal device in the communication process becomes a problem which needs to be solved urgently.

Fig. 1 is a schematic diagram of a scenario of a communication system to which an embodiment of the present application is applicable. As shown in fig. 1, the communication system 100 includes a network device 102, and the network device 102 may include multiple antenna groups. Each antenna group can include multiple antennas, e.g., one antenna group can include antennas 104 and 106, another antenna group can include antennas 106 and 110, and an additional group can include antennas 112 and 114. Each antenna group in fig. 1 shows 2 antennas, and each antenna group may use more or less antennas, and the present application is not limited thereto. Network device 102 can additionally include a transmitter chain and a receiver chain, each of which can comprise a plurality of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, antennas, etc.), as will be appreciated by one skilled in the art.
Network device 102 may communicate with a plurality of terminal devices, such as terminal device 116 and terminal device 122. However, it is understood that network device 102 may communicate with any number of terminal devices similar to terminal devices 116 or 122. Terminal devices 116 and 122 may be: such as a cellular phone, a smart phone, a laptop computer, a handheld communication device, a handheld computing device, a satellite radio, a global positioning system, a PDA, and/or any other suitable device for communicating over the wireless communication system 100.
As shown in fig. 1, terminal device 116 is in communication with antennas 112 and 114, where antennas 112 and 114 transmit information to terminal device 116 over a forward link 118 and receive information from terminal device 116 over a reverse link 120. In addition, terminal device 122 is in communication with antennas 104 and 106, where antennas 104 and 106 transmit information to terminal device 122 over forward link 124 and receive information from terminal device 122 over reverse link 126.
For example, in a Frequency Division Duplex (FDD) system, forward link 118 can utilize a different frequency band than that used by reverse link 120, and forward link 124 can utilize a different frequency band than that used by reverse link 126.
As another example, in Time Division Duplex (TDD) systems and full duplex (full duplex) systems, forward link 118 and reverse link 120 may utilize a common frequency band and forward link 124 and reverse link 126 may utilize a common frequency band.
Each group of antennas and/or area designed for communication is referred to as a sector of network device 102. For example, antenna groups may be designed to communicate to terminal devices in a sector of the areas covered by network device 102. During communication by network device 102 with terminal devices 116 and 122 over forward links 118 and 124, respectively, the transmitting antennas of network device 102 can utilize beamforming to improve signal-to-noise ratio of forward links 118 and 124. Moreover, mobile devices in neighboring cells can be subject to less interference when network device 102 utilizes beamforming to transmit to terminal devices 116 and 122 scattered randomly through an associated coverage than if the network device were transmitting through a single antenna to all its terminal devices.
At a given time, network device 102, terminal device 116, or terminal device 122 may be a wireless communication transmitting apparatus and/or a wireless communication receiving apparatus. When sending data, the wireless communication sending device may encode the data for transmission. Specifically, the wireless communication transmitting device may obtain (e.g., generate, receive from other communication devices, or save in memory, etc.) a number of data bits to be transmitted over the channel to the wireless communication receiving device. Such data bits may be contained in a transport block (or multiple transport blocks) of data, which may be segmented to produce multiple code blocks.
Furthermore, the communication system 100 may be a public land mobile network PLMN (public land mobile network) network or a device-to-device (D2D) network or a machine-to-machine (M2M) network or other networks, and fig. 1 is a simplified schematic diagram for easy understanding only, and other network devices may be included in the network, which is not shown in fig. 1.
For convenience of description, the following description will use a terminal device as a UE as an example.
Fig. 2 is a schematic flow diagram of a network device configuring capabilities of a terminal device. The flow chart shown in fig. 2 may include steps 210-230, which are described in detail below with respect to steps 210-230, respectively.
In step 210, the terminal device reports the capability that the terminal device can support to the network device.
In the communication process, the terminal device needs to report, to the network device, capabilities that the terminal device can support, where the capabilities may include but are not limited to: the multi-carrier capability of the terminal device, the multiple-input multiple-output (MIMO) capability of the terminal device, the radio frequency capability of the terminal device, the configuration parameter of Discontinuous Reception (DRX) of the terminal device, and so on.
In step 220, the network device configures the terminal device with the capabilities of the terminal device.
The network device may configure the terminal device with capabilities for data transmission, which may include but are not limited to: multi-carrier capability of the terminal device, radio frequency capability of the terminal device, MIMO capability of the terminal device, DRX parameters of the terminal device, and the like.
It should be understood that, in the process of configuring the capability to the terminal device, the network device may configure the capability according to the capability that can be supported and reported by the terminal device, or may configure the capability of the terminal device by itself.
In step 230, the terminal device performs data transmission according to the configured capability of the network device.
During the communication process, the terminal device can transmit data according to the configured capability of the network device.
Taking the example that the terminal device performs data transmission according to the MIMO capability configured by the network device, if the MIMO capability configured by the network device for the terminal device is 4X4MIMO (4 receiving links, 4 transmitting links). During the process of receiving data, the terminal device needs to open the 4 receiving radio frequency chains, and receive a signal with a bandwidth of 20MHz on the 4 receiving radio frequency chains. In the process of transmitting data, the terminal device needs to open the 4 transmit rf chains, and transmit a signal with a bandwidth of 20MHz on the 4 transmit rf chains.
Taking the example that the terminal device performs data transmission according to the multi-carrier capability configured by the network device, if the multi-carrier capability configured by the network device for the terminal device is 1 rf chain, data of 1 carrier is received. Assuming that the UE can support simultaneous reception of 2 carriers using 2 radio frequency chains, the bandwidth of the communication system is 20MHz. During the data receiving process, the terminal device needs to open the 2 receiving rf chains and receive a signal with a bandwidth of 20MHz on the 2 receiving rf chains.
Taking the case that the terminal device performs data transmission according to the DRX parameter configured by the network device, if the DRX parameter configured by the network device for the terminal device is a DRX cycle of 1s, the on duration state in each DRX cycle is 10ms. The terminal device may receive the data signal within 10ms of the on duration.
In the prior art, the UE can report smaller capacity only when the overheating problem occurs, and the network equipment can reconfigure the capacity of the UE according to the minimum capacity reported by the UE, so that the power of the UE is reduced, the heating of the UE is reduced, and the overheating problem of the UE is solved.
However, when the UE does not overheat, there is a space for power consumption optimization, so that the power consumption of the UE can be reduced. The following takes the influence of the configuration of the multiple-input multiple-output (MIMO) capability, the multi-carrier capability, and the Discontinuous Reception (DRX) of the UE on the power consumption as an example, and gives a detailed example of the space where the power consumption may be optimized when the UE does not have the overheating problem.
First, the influence of the MIMO capability of the UE on the power consumption will be described as an example.
When receiving a wireless signal, the UE needs to open a receiving radio frequency chain to receive the wireless signal. Assuming that the UE can configure 4 receiving radio frequency chains, the bandwidth of the communication system is 20MHz. Then the UE needs to open the 4 receiving rf chains and receive signals with a bandwidth of 20MHz on the 4 receiving rf chains. The UE extracts the resources scheduled by the network equipment for the UE from the 20MHz signal, and uses the scheduled resources to perform baseband decoding work of the signal.
For example, in 1 time unit, the power consumption of the UE to open 1 radio frequency link for 20MHz signal reception is 1X; the power consumed by the UE for carrying out channel decoding on the information quantity of 1 unit is 1Y; the power consumed by the UE for 4X4MIMO (4 receive chains, 4 transmit chains) reception is 1M, and the power consumed for 4X2MIMO (2 receive chains, 4 transmit chains) reception is 1N, where 1m > < 1n.
Assume that the UE needs to receive 1 unit of information amount from the network device in 1 unit of time. If the network device configures UE for 4X4MIMO reception, UE needs to open 4 reception radio frequency links, and power consumption of UE is 4X +1M +1Y. If the network device configures the UE to perform 4X2MIMO (2 receiving links, 4 transmitting links) reception, the UE needs to open 2 receiving radio frequency links, and the power consumption is 2x +1n +1y.
Since 4X +1M +1Y >.
Next, the influence of the multi-carrier capability of the UE on the power consumption will be described as an example.
When receiving a wireless signal, the UE needs to open a receiving radio frequency chain to receive the wireless signal. Where there may be 1 radio frequency chain receiving 1 carrier of data. Assuming that the UE can support simultaneous reception on 2 carriers using 2 radio frequency chains, the bandwidth of the communication system is 20MHz. The UE needs to open the 2 receiving radio frequency chains, and receive a signal with a bandwidth of 20MHz on the 2 receiving radio frequency chains, where the UE extracts a resource scheduled by the network device for the UE from the 20MHz signal, and performs a baseband decoding operation on the signal using the scheduled resource.
For example, in 1 time unit, the power consumption of the UE to open 1 radio frequency link for 20MHz signal reception is 1X; the power consumed by the UE to perform channel decoding for 1 information amount unit is 1Y.
Assume that the UE needs to receive 1 unit of information amount from the network device in 1 unit of time. If the network equipment configures the UE to receive 2 carriers, the UE needs to open 2 receiving radio frequency links, and the power consumption is 2X +1Y; if the network device configures the UE to receive 1 carrier, the UE needs to open 1 receiving radio frequency link, and the power consumption is 1X +1Y.
Since 2x +1y >.
Finally, the influence of the configuration of DRX of the UE on power consumption is taken as an example for explanation.
When receiving a wireless signal, the UE needs to open a receiving radio frequency chain to receive the wireless signal. When the UE receives a signal, if the network device has data to be sent to the UE within 1 time unit, the UE needs to receive control signaling (for example, receiving the control signaling may consume 1X energy) and receive a data signal (for example, receiving the data signal may consume 1Y energy) within the time unit; if the network device has no data to send to the UE in 1 time unit, the UE needs to blindly detect the control signaling sent by the network device in 1 time unit (for example, receiving the control signaling may consume 1X energy).
In the design of a communication system, in order to avoid that the UE opens a receiving radio frequency link but cannot receive data, the system saves the power consumption of the UE through the technology of DRX. When using the DRX technique, the system configures the UE with a DRX cycle. In one DRX cycle, including an on duration state, the UE needs to turn on the receiving radio frequency chain for data reception during the time of the on duration state, and turn off the receiving radio frequency chain during other times, so as to save power consumption. However, even in the on duration state, if there is no data signal in the on duration state, the UE still needs to detect the control signal every time unit in the on duration state, thereby causing power consumption of the UE.
As an example, if a user is using WeChat for short message service, the frequency of receiving short messages is 2 s/bar, and each reception requires 1ms. For this service, the configuration of DRX power optimization may be that the DRX cycle is 2s, and the on duration status in each DRX cycle is 1ms. If the DRX configured by the network device does not match the current service, for example, the DRX cycle configured by the network device is 1s, and the on duration status in each DRX cycle is 10ms. In the 1s period, the UE can receive the short message only within 1ms, and there is no data signal within 9ms of the on duration state, but the UE needs to perform blind detection on the control signal within 9ms of the on duration state, thereby causing power consumption of the UE.
Thus, for saving power consumption of the UE using the DRX technique, it is still required that the DRX cycle matches the ongoing traffic on the UE, so that power consumption of the UE can be reduced.
In summary, when the terminal device does not overheat, there is a space for optimizing power consumption, so that the power consumption of the UE can be reduced.
The embodiment of the application provides a method for optimizing the power of terminal equipment, which can optimize the power of the terminal equipment (for example, UE) in the communication process, so as to achieve the purpose of saving the power consumption of the terminal equipment.
The following describes in detail a method for power optimization of a terminal device provided in an embodiment of the present application.
Fig. 3 is a schematic flowchart of a terminal device power optimization method provided in an embodiment of the present application. The method of FIG. 3 may include steps 310-320, with steps 310-320 described in detail below, respectively:

The above-described various implementations are described in detail with reference to specific embodiments, and are not described in detail here.
In step 320, the terminal device sends the first information to the network device.
In the embodiment of the application, the terminal device may dynamically adjust the capability and/or DRX parameter information reported to the network device according to the condition of the service being used and/or the condition of the channel quality, and may perform power optimization on the terminal device (e.g., UE) during the communication process, thereby achieving the purpose of reducing the power consumption of the terminal device.
In the embodiment of the application, the terminal device reports the supportable capability and/or the DRX parameter to the network device, and the network device may configure the capability and/or the DRX parameter of the terminal device after receiving the information reported by the terminal device. As an example, the network device may send acknowledgement information to the terminal device, which may be used to acknowledge the terminal device's reported capabilities and/or DRX parameters that may be supported. As another example, the network device may send configuration information to the terminal device, where the configuration information may be used to indicate that the network device refers to the capability and/or DRX parameters that can be supported and reported by the terminal device, and configure the capability and/or DRX parameters of the terminal device.
The terminal device may perform data transmission according to the capability configured by the network device and/or the DRX parameters.
In the following, a terminal device is taken as a UE, and capabilities and/or DRX parameter information that the terminal device may support are illustrated.
In the communication process, the UE may report the supported UE capability to the network device in advance. The reported UE capabilities may include, but are not limited to: the carrier capability of the UE, the modulation mode of the UE, the radio frequency capability of the UE, the uplink transmission capability of the UE, the downlink transmission capability of the UE, and the like. Taking the carrier capability of the UE as an example, the UE may report the number of carriers that the UE can support to the network device. For example, the UE may support receiving data for 1 carrier or data for 2 carriers.
Taking the modulation mode of the UE as an example, the UE may report the modulation mode that the UE can support to the network device. Common modulation schemes may include, for example: 256 Quadrature Amplitude Modulation (QAM) modulation, 640QAM, 1024QAM, and the like.
Taking the radio frequency capability of the UE as an example, the UE may report the radio frequency capability that the UE can support to the network device. That is, when the UE performs radio receiving and transmitting, it needs to tune the transmitting circuit and the receiving circuit to the corresponding radio frequency, and the UE can report the capability of the usable radio frequency to the network device. Radio frequency capabilities may include, but are not limited to: band (band) information, band combination (band combination) information, bandwidth class (band class) information, and the like.
It should be understood that the frequency band information may be used to indicate on which frequency bands the UE can receive and transmit signals, for example, the frequency band information indicates n77, n78, n79, which indicates that the UE can use the frequency bands n77, n78, n79 for data transmission and reception. The band combination information may indicate on which band combinations the UE can receive and transmit signals, such as the band combination information indication (n 77, n 78), (n 78, n 79), indicating that the UE can use the band combination (n 77, n 78), or the band combination (n 78, n 79) for data transmission and reception. The bandwidth class information may indicate a size of a bandwidth that the UE can support on a certain frequency band, for example, the bandwidth class information indicates 20MHz, or 40MHz, which indicates a size of a frequency band bandwidth of 20MHz that the UE can support.
Generally, the three parameters can be used together, such as n77-20mhz and n78-40MHz, which means that the UE can receive and transmit data using a bandwidth size of 20MHz on the frequency band n77 or 40MHz on the frequency band n 78. Another example is (n 77-20mhz, n78-40 Mhz), this indicates that the UE may use the frequency band combination (n 77, n 78) for data reception and transmission, and uses a 20Mhz bandwidth size on the frequency band n77 and a 40Mhz bandwidth size on n 78.
Taking the uplink transmission capability of the UE as an example, the UE may report the uplink transmission capability that the UE can support to the network device. For example, the uplink transmission capability may include, but is not limited to: the number of radio frequency chains for uplink transmission, the number of multiple-input multiple-output (MIMO) layers or streams for uplink transmission, the number of MIMO ranks for uplink transmission, and the number of ports for uplink transmission.
Taking downlink transmission capability of the UE as an example, the UE may report the downlink transmission capability that the UE can support to the network device. For example, the downlink transmission capability may include, but is not limited to: the number of radio frequency chains used for downlink transmission, the number of MIMO layers or streams used for downlink transmission, the number of MIMO ranks used for downlink transmission, and the number of ports used for downlink transmission.
In the communication process, the UE may report a more matched DRX parameter to the network device in advance. The reported DRX parameters may include, but are not limited to: a DRX cycle, a DRX duration (on duration), and a DRX active duration (in active).
Taking the example that the UE determines the supportable capability and/or DRX parameter information sent to the network device according to the current power information, when the power of the UE is low, the UE may send a report of the low UE capability and/or a more matched DRX parameter to the network device. The network equipment can be enabled to configure the capability and/or DRX parameters of the UE in a targeted manner, and the UE can be enabled to perform power consumption optimized transmission.
The following describes details of the UE determining supportable capability and/or DRX parameter information sent to the network device according to the channel quality of the serving cell.
The UE may determine the UE capability and/or DRX parameters matching the APP requirement sent to the network device according to the current channel quality condition of the serving cell. The network equipment can be enabled to configure the capability and/or DRX parameters of the UE in a targeted manner, and the UE can be enabled to perform power consumption optimized transmission.
As one example, the UE may detect information such as a current channel Reference Signal Received Power (RSRP), a Reference Signal Received Quality (RSRQ), a Received Signal Strength Indication (RSSI), a signal to interference plus noise ratio (SINR), a rank of a serving cell channel, etc. of the serving cell. If one or more of the above information satisfies the threshold condition, the UE may report a lower UE capability and/or a DRX parameter more matched to the current service to the network device, so as to reduce the power consumption of the UE.
Optionally, in some embodiments, the UE may determine the carrier capabilities that the UE may support to send to the network device according to channel quality information of the serving cell (e.g., one or more of RSRP, RSRQ, RSSI, SINR, rank of serving cell channel, etc.).
Optionally, in some embodiments, the UE may determine a modulation scheme that the UE may support to send to the network device according to channel quality information of the serving cell (e.g., one or more of RSRP, RSRQ, RSSI, SINR, rank of serving cell channel, etc.).
Optionally, in some embodiments, the UE may determine the radio frequency capabilities that the UE may support to send to the network device according to channel quality information of the serving cell (e.g., one or more of RSRP, RSRQ, RSSI, SINR, rank of serving cell channel, etc.).
Optionally, in some embodiments, the UE may determine, according to the channel quality information (e.g., one or more of RSRP, RSRQ, RSSI, SINR, rank of serving cell channel, etc.) of the serving cell, a downlink transmission capability that the UE may support to send to the network device.
Optionally, in some embodiments, the UE may determine the uplink transmission capability that the UE may support to send to the network device according to the channel quality information of the serving cell (e.g., one or more of RSRP, RSRQ, RSSI, SINR, rank of serving cell channel, etc.).
Optionally, in some embodiments, the UE may determine the parameters of DRX that the UE may support to send to the network device according to channel quality information of the serving cell (e.g., one or more of RSRP, RSRQ, RSSI, SINR, rank of serving cell channel, etc.).
It should be understood that, in this embodiment of the present application, the above multiple embodiments may be combined, and the UE may further determine, according to the channel quality information of the serving cell (e.g., one or more information of RSRP, RSRQ, RSSI, SINR, rank of serving cell channel, and the like), at least one of the following that the UE can support, which is sent to the network device:
carrier capabilities that the UE can support;
modulation modes that the UE can support;
radio frequency capabilities that the UE can support;
downlink transmission capability that the UE can support;
uplink transmission capability that the UE can support;
parameters of DRX that the UE can support.
In the following, details are described by taking an example that the UE determines, according to the currently-carried service information, supportable capability and/or DRX parameter information that can be sent to the network device.
There are various specific implementation manners for the UE to determine the E capability and/or DRX parameter information sent to the network device according to the currently carried service information, and the following description is given with reference to specific embodiments. The UE capability and/or the DRX parameter that the UE sends to the network device according to the requirement of the bearer service may refer to the description of the reported UE capability and DRX parameter, which is not described herein again.
Optionally, in some embodiments, the UE may determine, according to a name of a current Application (APP), UE capability and/or DRX parameters matching requirements of the APP, which are sent to the network device. The network equipment can be enabled to configure the capability and/or DRX parameters of the UE in a targeted manner, and the UE can be enabled to perform power consumption optimized transmission.
For example, if the current APP name of the UE is a service with low requirement on transmission rate, such as WeChat, microblog, federation, QQ, etc., the UE may report a lower UE capability and/or a DRX parameter more matched with the current service to the network device. Thereby enabling a reduction in UE power consumption.
Optionally, in some embodiments, the UE may determine, according to the service operated by the current APP, the UE capability and/or DRX parameters matching the requirement of the APP and sent to the network device. The network equipment can be enabled to configure the capability and/or DRX parameters of the UE in a targeted manner, and the UE can be enabled to perform power consumption optimized transmission.
For example, if the service currently operated by the UE APP is an interactive short message service, a web browsing service, an interactive video call, or the like. The UE can report lower UE capability and/or DRX parameters more matched with the current service to the network equipment, so that the power consumption of the UE can be reduced.
Optionally, in some embodiments, the UE may determine, according to the traffic communication index of the current APP, the UE capability and/or DRX parameter that matches the requirement of the APP and is sent to the network device. The network equipment can be enabled to configure the capability and/or DRX parameters of the UE in a targeted manner, and the UE can be enabled to perform power consumption optimized transmission.
For example, in a service currently carried by the UE, when a service communication index of the APP meets a certain condition, the UE may report a lower UE capability or a DRX parameter more matched with the current service to the network device, so that power consumption of the UE may be reduced. If the transmission rate of the video watched by the video APP is less than the threshold, or the transmission delay of the video APP is greater than the threshold, or the information transmission duty ratio is lower than the threshold, or the quality of service (QoS) of the current communication service meets a certain condition, the UE may report the lower UE capability and/or the DRX parameter more matched with the current service to the network device.
The above embodiments may be implemented individually, or a plurality of embodiments may be combined. For example, the terminal device may determine the UE capability reported to the network device according to one of the loaded service information, the power information, and the channel quality information of the serving cell. For another example, the terminal device may determine the DRX parameter reported to the network device according to one of the carried service information, the power information, and the channel quality information of the serving cell. For another example, the terminal device may determine the UE capability reported to the network device according to a combination of multiple information in the carried service information, the power information, and the channel quality information of the serving cell. For another example, the terminal device may determine the DRX parameter reported to the network device according to a combination of multiple information in the carried service information, the power information, and the channel quality information of the serving cell.
Optionally, in some embodiments, when the UE can meet the requirement according to the name and the type of a certain service running in the current APP and the communication index of the service, the UE may report a lower UE capability to the network device. The UE may be enabled for power consumption optimized transmission. The UE capabilities may include, but are not limited to, at least one of: carrier capability, modulation mode, radio frequency capability, downlink transmission capability, and uplink transmission capability.
Optionally, in some embodiments, if the name and the type of a certain service running in the current APP of the UE and the communication index of the service meet the requirements, the UE may report the DRX parameter more matched with the current service to the network device. The UE may be enabled for power consumption optimized transmission. The DRX parameters may include, but are not limited to, at least one of: a DRX cycle, a DRX duration (on duration), and a DRX active duration (in active).
Optionally, in some embodiments, if the channel quality of the serving cell in which the UE is located meets a condition (for example, RSRP, RSRQ, RSSI, and SINR are greater than a threshold condition), for a certain service running in a certain APP, and when a communication index of the service meets a requirement, the UE may report a lower UE capability to the network device, so that the UE performs transmission with optimized power consumption.
Optionally, in some embodiments, if the channel quality of the serving cell in which the UE is located meets a condition (for example, RSRP, RSRQ, RSSI, and SINR are greater than a threshold condition), for a certain service running in a certain APP, and when a communication index of the service meets a requirement, the UE may report, to the network device, a DRX parameter that is more matched with the current service, so that the UE may perform transmission with optimized power consumption.
Optionally, in some embodiments, if the channel quality of the serving cell where the UE is located meets a condition (for example, RSRP, RSRQ, RSSI, and SINR are greater than a threshold condition), for a certain service running in a certain APP, and when a communication index of the service meets a requirement, the UE reports a lower UE capability to the base station, and the UE may also report a DRX parameter more matched with the current service to the network device, so that the power of the UE may be optimized.
In this embodiment of the present application, the first information (for example, the first information may include lower UE capability reported by the UE to the network device and/or DRX parameter information more matched with the current service) may be carried on Radio Resource Control (RRC) signaling, may also be carried on media access control element (MAC CE) signaling, and may also be carried on physical layer dynamic signaling, which is not specifically limited in this application.
Take the example that the UE reports the UE capability to the network device. The UE may send a plurality of capabilities to the network device, where one of the plurality of capabilities may be a default capability and others may be used for flexible configuration. The UE may send, to the network device, capability indication information indicating one of a plurality of capabilities. The indication information may be RRC signaling, MAC CE, or physical layer dynamic signaling. The network device may also send, to the UE, indication information for confirming the UE capability or configuring the UE capability, where the indication information may be RRC signaling, MAC CE, or physical layer dynamic signaling.
Take UE reporting DRX parameter information to network equipment as an example. The UE may send multiple DRX parameter information to the network device, and the UE may send an indication of a parameter to the network device, which may indicate one of multiple DRX parameters. The indication information may be RRC signaling, MAC CE, or physical layer dynamic signaling. The network device may also send, to the UE, indication information for confirming or configuring the DRX parameter information, where the indication information may be RRC signaling, MAC CE, or physical layer dynamic signaling.
In the following, a specific implementation manner of how the UE reports the lower UE capability in the embodiment of the present application is described in more detail with reference to a specific example. It should be noted that the following examples are merely provided to assist those skilled in the art in understanding the embodiments of the present application, and are not intended to limit the embodiments of the present application to the specific values or specific scenarios illustrated.

Fig. 4 is a schematic flowchart of a method for optimizing power of a terminal device according to another embodiment of the present application. The method of fig. 4 may include steps 410-430, with steps 410-430 described in detail below, respectively.
In step 410, the UE transmits a first capability to the network device.
The UE may transmit a first capability to the network device, which may include UE baseband processing capability or UE radio frequency capability.
The UE baseband processing capability may be used to indicate a modulation scheme that the UE can support, for example, downlink 256QAM, downlink 1024QAM, uplink 64QAM, uplink 256QAM, and the like. The UE baseband processing capability may also be used to indicate a multi-antenna transmission capability that the UE can support, for example, a downlink 4-port transmission capability, or a downlink 2-port transmission capability, or an uplink 4-port transmission capability, or an uplink 2-port transmission capability.
The UE radio frequency capability may be used to indicate the capability of radio frequencies that the UE may support, and may include frequency bands, frequency band combination information, bandwidth class information.
In step 420, the UE determines the second capability according to one or more of the carried traffic information, power information, and channel quality of the serving cell.
The UE may determine a second capability to be sent to the network device according to at least one of the loaded service information, the power information, and the channel quality information of the serving cell, where the second capability may be a UE capability matching the current APP or the channel quality of the cell. The network equipment configures the capability and/or DRX parameters of the UE in a targeted manner, so that the UE can perform power consumption optimized transmission.
It is to be understood that the second capability corresponds to the first information determined by the UE above, and the second capability may include, but is not limited to: the carrier capability of the UE, the modulation mode of the UE, the radio frequency capability of the UE, the uplink transmission capability of the UE, the downlink transmission capability of the UE, the DRX cycle, the DRX duration (on duration), the DRX active duration (in active), and the like.
The specific process of the UE determining the second capability to be sent to the network device according to at least one of the service information, the power information, and the channel quality information of the serving cell may refer to the above description, and is not described herein again.
In step 430, the UE transmits the second capability to the network device.
The UE may determine a second capability according to one or more of traffic information, power information, and channel quality of a serving cell, and may send the determined second capability to the network device, where the second capability may include a UE baseband processing capability or a UE radio frequency capability, and the second capability may be smaller than the first capability.
As one example, the UE baseband processing capability of the second capability indication is less than the UE baseband processing capability of the first capability indication. For example, the modulation order of the second capability indication is smaller than the modulation order of the first capability indication. As another example, the multi-antenna transmission capability of the second capability indication is less than the multi-antenna transmission capability of the first capability indication.
As another example, the UE radio frequency capability of the second capability indication is less than the UE radio frequency capability of the first capability indication. For example, the number of supported frequency bands of the second capability indication is smaller than the number of supported frequency bands of the first capability indication. As another example, the number of band combinations indicated by the second capability is smaller than the number of band combinations indicated by the first capability. As another example, the number of carriers in the band combination indicated by the second capability is smaller than the number of carriers in the band combination indicated by the first capability. As another example, the second capability indication has a lower bandwidth level than the first capability indication.
In the embodiment of the application, the terminal device may dynamically adjust the capability and/or DRX parameter information reported to the network device according to the condition of the service being used and/or the condition of the channel quality, and may perform power optimization on the terminal device (e.g., UE) during the communication process, thereby achieving the purpose of reducing the power consumption of the terminal device.
