Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an energy consumption management method and device. Background Art

[0002] The first version of 5G mobile communication was completed in 2018. Based on the first version of the 5G standard, equipment manufacturers and operators have begun to produce equipment and deploy 5G networks. Although many new technical features (such as larger transmission bandwidth, larger subcarrier spacing, smaller processing units, and more antennas) are introduced in the 5G system to meet performance requirements, the introduction of these technical features has led to a several-fold increase in energy consumption of 5G terminals compared to 4G. However, the size of terminal equipment and the battery capacity per unit volume have not been significantly improved, making it difficult for the battery life of 5G terminal equipment to meet daily use needs. This situation will greatly affect the user experience, so how to save terminal power consumption is a key issue that needs to be solved urgently. Summary of the invention

[0003] The embodiments of the present application provide an energy consumption management method and apparatus for reducing the energy consumption of terminal equipment.

[0004] In a first aspect, an embodiment of the present application provides a method, applied to a terminal device, the method comprising:

[0005] receiving first indication information and second indication information;

[0006] Based on the first indication information and the second indication information, a physical downlink control channel of the serving cell is monitored.

[0007] In a second aspect, an embodiment of the present application provides a device, applied to a terminal device, the device comprising:

[0008] A receiving unit, configured to receive first indication information and second indication information;

[0009] A monitoring unit is used to monitor the physical downlink control channel of the serving cell based on the first indication information and the second indication information.

[0010] In a third aspect, an embodiment of the present application provides a terminal device, comprising a processor, a memory, a communication interface, and one or more programs, wherein the processor is connected to the communication interface, the one or more programs are stored in the memory and configured to be executed by the processor, and the program includes instructions for executing the steps in the method described in the first aspect of the embodiment of the present application.

[0011] In a fourth aspect, an embodiment of the present application provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, wherein the computer program enables a computer to execute part or all of the steps described in the method described in the first aspect of the embodiment of the present application.

[0012] In a fifth aspect, an embodiment of the present application provides a computer program product, wherein the computer program product includes a non-transitory computer-readable storage medium storing a computer program, and the computer program is operable to cause a computer to execute some or all of the steps described in the method described in the first aspect of the embodiment of the present application. The computer program product may be a software installation package.

[0013] It can be seen that in the embodiment of the present application, the first indication information and the second indication information are first received, and then based on the first indication information and the second indication information, the physical downlink control channel of the service cell is monitored. Since the terminal device monitors the service cell based on the first indication information and the second indication information, rather than monitoring all cells, it is beneficial to reduce the energy consumption of the terminal device.

[0018] The terms used in the implementation mode of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The terms "first", "second", "third" and "fourth" in the specification and claims of this application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0019] The terminal device in the embodiment of the present application is a device with wireless communication function, which can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface (such as ships, etc.); it can also be deployed in the air (for example, on airplanes, balloons, satellites, etc.). The terminal device can be a mobile phone, a tablet computer (pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control (Industrial Control), a wireless terminal in self-driving, a wireless terminal in remote medical care (Remote Medical), a wireless terminal in smart grid (Smart Grid), a wireless terminal in smart home (Smart Home), etc. The terminal device can also be a handheld device with wireless communication function, a vehicle-mounted device, a wearable device, a computer device, or other processing equipment connected to a wireless modem, etc.

[0020] The battery life of terminal devices is an important aspect of user experience, which will affect the user experience of 5G terminals and / or services. To this end, the 5G system introduces some technical features to indicate changes in terminal behavior, so that the terminal device can enter a power-saving state under appropriate conditions to save terminal power. This state switching involves multiple configurations or state changes, including configurations indicating whether the terminal device wakes up to monitor the physical downlink control channel (PDCCH) wake-up signal (WUS), bandwidth unit (BandWidth Part, BWP) switching (switching to a smaller BWP) or switching to a dormancy bandwidth unit (dormancy BWP) (dormancy bandwidth unit does not need to monitor PDCCH), PDCCH detection period switching (switching to a larger period), skipping some PDCCH monitoring (PDCCH monitoring skipping) and using cross-slot scheduling with a minimum scheduling interval greater than 0, etc.

[0021] In addition to the above energy-saving methods, in the standard technology research of 5G NR Release 16, a secondary discontinuous reception timer group (SecondaryDRX group) was introduced for FR2 cells to reduce the power consumption of terminal equipment in FR2 cells. However, the introduction of the Secondary DRX group will cause the following problems:

[0022] The same secondary cell group may have different DRX configurations. If one secondary cell in a group is transmitting data (such as secondary cell 2), the other secondary cells are not transmitting data at all (such as secondary cell 1). If the network device can indicate dormancy through WUS to save power, then both secondary cell 1 and secondary cell 2 will switch to the sleep bandwidth unit, which will cause the data transmission of secondary cell 2 to be interrupted. However, if in order to ensure the data transmission of secondary cell 2, the network device indicates a non-sleep bandwidth unit, and both secondary cell 1 and secondary cell 2 will monitor PDCCH, then monitoring PDCCH on secondary cell 1 is a waste of energy. Therefore, how to save power as much as possible without interrupting transmission is an urgent problem to be solved.

[0023] In addition, if the network device only needs to use the FR2 cells to transmit data (only the FR2 cells configured with SecondaryDRX need to be woken up), according to the current indication and process: using WUS to indicate wake-up, and then using the secondary cell dormancy indication (SCell dormancy indication) to switch the cell group without FR2 to dormancy, it may cause other cells in the cell group with FR2, and waking up other non-essential cells will also consume energy.

[0024] See also Figure 1 , Figure 1 A schematic diagram of a flow chart of an energy consumption management method provided in an embodiment of the present application includes the following steps:

[0025] Step 101: Receive first indication information and second indication information.

[0026] The bits in DCI format 2_6 are divided into multiple blocks, each block includes multiple bits, each block corresponds to a terminal device and each block contains two fields. The first bit in each block corresponds to the first field, and the remaining bits correspond to the second field. The first field is a wake-up indication (Wake-up indication), which is used to indicate whether the terminal device needs to wake up; the second field is a secondary cell dormancy indication (SCell dormancy indication), which is used to indicate which secondary cell groups need to switch to the dormancy bandwidth unit (dormancy BWP).

[0027] Each bit in the second field represents a secondary cell group.

[0028] The first indication information and the second indication information are located in the same DCI.

[0029] The first indication information may be a wake-up indication, and the second indication information may be a secondary cell sleep indication.

[0030] Step 102: Based on the first indication information and the second indication information, monitor the physical downlink control channel of the serving cell.

[0031] The serving cell may be all cells in the secondary cell group corresponding to the second indication information, or may be part of the secondary cells in the secondary cell group corresponding to the second indication information.

[0032] It can be seen that in the embodiment of the present application, the first indication information and the second indication information are first received, and then based on the first indication information and the second indication information, the physical downlink control channel of the service cell is monitored. Since the terminal device monitors the service cell based on the first indication information and the second indication information, rather than monitoring all cells, it is beneficial to reduce the energy consumption of the terminal device.

[0033] In a possible implementation manner, the monitoring a physical downlink control channel of a serving cell based on the first indication information and the second indication information includes:

[0034] When the first indication information is a first value, starting an activation duration timer, wherein the first indication information is the first value used to indicate starting the activation duration timer;

[0035] When the activation duration timer has been started and the second indication information is a second value, switching the secondary cell corresponding to the second indication information to a non-dormant bandwidth unit or maintaining it in the non-dormant bandwidth unit, so as to monitor a physical downlink control channel on the secondary cell corresponding to the second indication information, and the serving cell is the secondary cell corresponding to the second indication information;

[0036] When the activation duration timer has been started and the second indication information is a third value, if the serving cell is in a discontinuous reception activation state, it is determined that the serving cell does not switch to a sleep bandwidth unit to monitor a physical downlink control channel on the serving cell, and the serving cell is a secondary cell in a discontinuous reception activation state in the secondary cell group corresponding to the second indication information.

[0037] The activation duration timer may be a discontinuous reception activation duration timer (DRX Onduration-Timer).

[0038] Among them, the first value can be 1, and the first indication information is 1 for instructing the terminal device to start the activation duration timer. The first indication information can also be other values ​​for instructing the terminal device to start the activation duration timer.

[0039] Among them, the second value can be 1, and the second indication information is 1, which is used to instruct the terminal device to switch all secondary cells in the secondary cell group corresponding to the second indication information to the non-sleep bandwidth unit or keep them in the non-sleep bandwidth unit, so that the terminal device monitors the physical downlink control channel of the secondary cell corresponding to the second indication information. The second indication information can also be other values ​​used to instruct the terminal device to switch all secondary cells in the secondary cell group corresponding to the second indication information to the non-sleep bandwidth unit or keep them in the non-sleep bandwidth unit.

[0040] If a certain secondary cell in the secondary cell group corresponding to a certain bit in the second indication information is in a discontinuous reception activated state, the physical downlink control channel of the secondary cell is monitored.

[0041] For example, if the first indication information is 1 and the second indication information is 1, the secondary cell group corresponding to the second indication information includes secondary cell 1 and secondary cell 2. If secondary cell 1 is in a discontinuous reception activated state and secondary cell 2 is in a discontinuous reception inactivated state, after the activation duration timer is turned on, secondary cell 1 will be maintained in the non-sleep bandwidth unit and secondary cell 2 will be switched to the non-sleep bandwidth unit.

[0042] Among them, the third value is 0, and the second indication information is 0, which is used to instruct the terminal device not to switch the secondary cell in the secondary cell group corresponding to the second indication information that is in a discontinuous reception activated state to the sleep bandwidth unit, and to switch the secondary cell in the secondary cell group corresponding to the second indication information that is in a discontinuous reception inactivated state to the sleep bandwidth unit.

[0043] After the activation duration timer times out, the secondary cell in the discontinuous reception activated state in the secondary cell group corresponding to the second indication information is switched to the dormant bandwidth unit.

[0044] For example, if the second indication information is 0, the secondary cell group corresponding to the second indication information includes secondary cell 1 and secondary cell 2. If secondary cell 1 is in a discontinuous reception activated state and secondary cell 2 is in a discontinuous reception inactivated state, secondary cell 1 will not be switched to the sleep bandwidth unit, secondary cell 2 will be switched to the sleep bandwidth unit, and secondary cell 1 will be switched to the sleep bandwidth unit after the activation duration timer expires.

[0045] Since the terminal device only monitors the physical uplink control information of the secondary cell in the discontinuous reception activated state, and does not monitor the physical uplink control information of the secondary cell in the discontinuous reception inactivated state, it is beneficial to reduce the energy consumed by the terminal device in monitoring the physical uplink control information.

[0046] In a possible implementation manner, an activation duration timer and / or an inactivation duration timer on the secondary cell in the discontinuous reception activated state is in a counting state.

[0047] The inactivity duration timer may be a discontinuous reception inactivity duration timer (DRX Inactivity-Timer).

[0048] By adopting an activation duration timer and / or a non-activation duration timer, it is determined that the terminal device monitors the physical uplink control information of the secondary cell in the discontinuous reception activation state, thereby avoiding the terminal device from continuing to monitor the physical downlink control information after the secondary cell is in the discontinuous reception non-activation state, which is beneficial to reducing the energy consumption of the terminal device.

[0049] In a possible implementation manner, the monitoring a physical downlink control channel of a serving cell based on the first indication information and the second indication information includes:

[0050] When the first indication information is a fourth value, determining whether to start a first activation duration timer based on the second indication information;

[0051] When the second indication information is a fifth value, starting the first activation duration timer on the secondary cell group corresponding to the second indication information;

[0052] When the first activation duration timer is started, the second activation duration timer of the service cell is started to monitor the physical downlink control channel on the service cell. The service cell is a cell configured with a second activation duration timer in the secondary cell group corresponding to the second indication information.

[0053] The fourth value may be 0, and the first indication information is 0 and is used to indicate whether to start the first activation duration timer based on the second indication information.

[0054] The first activation duration timer may be a primary cell discontinuous reception activation duration timer (Pcell DRXOnduration-Timer).

[0055] The second activation duration timer may be a discontinuous reception activation duration timer (secondary DRXOnduration-Timer).

[0056] The second activation duration timer may be activated via RRC signaling.

[0057] Among them, the second activation duration timer is mainly for FR2 cells (FR2 cells are cells using frequency resources within the FR2 range), and helps FR2 cells quickly enter the dormant bandwidth unit by setting shorter activation duration timers and inactivation duration timers.

[0058] The fifth value may be 1, and the second indication information is 1, which is used to indicate starting the first activation duration timer on the secondary cell group corresponding to the second indication information.

[0059] Among them, among the secondary cells in the secondary cell group corresponding to the second indication information, some secondary cells may be FR2 cells, some secondary cells may not be FR2 cells, or all secondary cells may be FR2 cells.

[0060] Among them, for the cells in the secondary cell group corresponding to the second indication information, the non-FR2 cells are not configured with the second activation duration timer, and all the FR2 cells are configured with the second activation duration timer.

[0061] For example, if the secondary cell group corresponding to the second indication information includes three secondary cells (secondary cell 1, secondary cell 2 and secondary cell 3), if secondary cell 1 is a FR2 cell, secondary cell 2 and secondary cell 3 are not FR2 cells. Therefore, a second activation duration timer is configured on secondary cell 1, and a second activation duration timer is not configured on secondary cell 2 and secondary cell 3. Therefore, after starting the first duration timer on the secondary cell group, only the second activation duration timer of secondary cell 1 is started, so that the terminal device can monitor the physical downlink control information of secondary cell 1.

[0062] Since monitoring physical downlink control information of all cells in the secondary cell group when transmitting data in the FR2 cell will increase the energy consumption of the terminal device, monitoring the FR2 cell configured with the second activation duration timer is beneficial to reducing the energy consumption of the terminal device.

[0063] In a possible implementation, the method further includes:

[0064] When the second indication information is the sixth value, the first activation duration timer is not started so as not to monitor the physical downlink control channel on the secondary cell group corresponding to the second indication information.

[0065] The sixth value may be 0, or may be other values ​​that do not start the first activation duration timer.

[0066] Among them, the first activation duration timer is not started and the terminal device is in a sleep state.

[0067] Since the physical downlink control channel on the secondary cell group corresponding to the second indication information is not monitored when the first activation duration timer is not started, it is beneficial to avoid energy consumption of the terminal device.

[0068] It should be noted that the specific implementation process of this embodiment can refer to the specific implementation process described in the above method embodiment, which will not be described here.

[0075] When the first indication information is a first value, starting an activation duration timer, wherein the first indication information is the first value used to indicate starting the activation duration timer;

[0076] When the activation duration timer has been started and the second indication information is a second value, switching the secondary cell corresponding to the second indication information to a non-dormant bandwidth unit or maintaining it in the non-dormant bandwidth unit, so as to monitor a physical downlink control channel on the secondary cell corresponding to the second indication information, and the serving cell is the secondary cell corresponding to the second indication information;

[0079] In a possible implementation manner, the monitoring of a physical downlink control channel of a serving cell based on the first indication information and the second indication information, the program includes instructions for executing the following steps:
