Description

Configuration method and device of network energy-saving community

Technical field

The embodiments of this application relate to the field of communication technology.

Background technique

Since the NR (New Wireless) base station needs to work at a large bandwidth (such as 100MHz), it needs to use a large number of ports (64T/64R), a shorter TTI (transmission time interval) (such as 1ms), NR base station baseband processing, digital front-end, etc. The functional energy consumption overhead is significantly higher than that of LTE (Long Term Evolution) base stations. Moreover, NR's FR2 (frequency range 2) operating frequency (>6GHz) is higher. The higher the frequency, the greater the signal path loss. Therefore, the design principle of NR is to use narrower beams to transmit signals farther. In this way, the number of antenna units used by NR base stations for analog beamforming will be greatly increased, which will lead to an increase in the number of radio frequency units and radio frequency channels for transmitting and receiving signals. Each radio frequency channel is equipped with a power amplifier (PA) , the energy consumption of PA will account for about 80% of the energy consumption of the entire base station. As the number of PAs increases, the energy consumption of the base station will also increase. The current FR1 (frequency range 1) band AAU (active antenna unit) generally uses 192 antenna units and supports 64 channels, which is much larger than the maximum 8 channels of LTE.

According to operator statistics, the average energy consumption of an NR base station is more than three times that of an LTE base station. Nearly 50% of the cost for operators to deploy 5G (5th generation) networks is electricity expenses. More importantly, even when there is no business, the energy consumption of the NR base station is still very high, because even when there is no business, the base station still needs to send public signals, such as SSB (Synchronization Signal Block), SIB1 (First System Information Block) ) and SI (system information), etc., thus greatly reducing the energy usage efficiency of NR base stations. NR network energy saving is an urgent issue that needs to be solved.

In the existing technology, in order to save energy consumption of NR base stations, in 3GPP Rel-15, NR cells are supported to stop sending system information (SI). The NR cell broadcasts in SIB1 whether to send SI. If the UE (user equipment) needs to receive SI (for example, when the UE determines that it needs to update the saved SI), it can request the base station to resume sending SI. The NR base station resumes sending SI when receiving the relevant UE request.

In 3GPP Rel-15/Rel-16 (Third Generation Partnership Project version 15/version 16), the network energy saving of NR was studied, and the proposed solution was based on the traffic volume of NR cells and their adjacent cells, Information such as UE measurement reports dynamically starts and stops the reception and/or transmission of signals of the NR cell. When the reception and transmission of signals of the NR cell are stopped, the cell enters an energy-saving state. This can achieve the purpose of turning off the signal transceiver device in the NR cell to save energy consumption when the traffic volume is low. Whether NR enters the energy-saving state can be decided by the NR cell itself (distributed network energy-saving solution) or by OAM (centralized network energy-saving solution). For example, when the traffic volume of the NR cell is lower than a certain threshold, it is determined to enter the energy saving state.

Figure 1 is a schematic diagram of the distributed network energy saving solution. As shown in Figure 1, in the distributed network energy saving solution, when the NR cell enters the energy saving state, the base station switches the UE to the adjacent cell and notifies the adjacent NR base station or LTE base station. The NR cell has entered the energy-saving state, and the adjacent NR/LTE base station will bear the coverage area and business volume of the NR cell. Afterwards, the adjacent NR/LTE base station will determine whether to request the NR cell that has entered the energy-saving state to resume normal operation based on its own traffic volume, UE measurement report and other information. For example, when the traffic volume of adjacent NR/LTE base stations reaches a certain threshold, the NR cell that requests to enter the energy-saving state is triggered to resume normal operation. When the NR cell resumes normal operation, that is, restarts signal reception and/or transmission, some UEs that were previously switched to adjacent NR/LTE cells will switch back to the NR cell.

It should be noted that the above introduction to the technical background is only provided to facilitate a clear and complete description of the technical solution of the present application and to facilitate the understanding of those skilled in the art. It cannot be considered that the above technical solutions are known to those skilled in the art just because these solutions are described in the background art section of this application.

Contents of the invention

The inventor found that in the existing technology, if an NR cell enters the energy-saving state, it means that the cell stops receiving and transmitting all signals. Therefore, the UE originally connected to the cell must switch to an adjacent cell, and the UE originally stationed in the cell must switch to an adjacent cell. The UE will perform cell re-selection and camp on the adjacent cell. When the NR cell dynamically enters the energy-saving state multiple times, the UE will frequently switch out of the NR cell or perform frequent cell reselection, which will affect the user experience. In addition, migration of UEs in energy-saving cells to adjacent cells will inevitably increase the load level of adjacent cells and affect the service quality of UEs in adjacent cells.

In response to the above problems, embodiments of the present application provide a method and device for configuring a network energy-saving cell. When the network enters energy saving, the energy-saving BWP (or sleep BWP) is used to continue serving the terminal device, and the network indicates the configuration of the energy-saving BWP to the terminal device. This is to avoid migrating terminal equipment to adjacent cells after the network enters energy saving, causing service interruption of terminal equipment and increasing the load level of adjacent cells.

According to one aspect of the embodiment of the present application, a configuration device for a network energy-saving cell is provided, which is configured on network equipment. The device includes:

A sending unit that sends first information to the terminal device, the first information being used to configure the second bandwidth part BWP to the serving cell of the terminal device, so that the network device uses the second BWP to serve the Terminal Equipment;

Wherein, the energy required by the network device when running the second BWP is lower than the energy required when running the first BWP.

According to another aspect of the embodiment of the present application, a device for configuring a network energy-saving cell is provided, which is configured on a terminal device. The device includes:

A receiving unit that receives the first information sent by the network device, the first information being used to configure the second bandwidth part BWP to the serving cell of the terminal device, so that the network device uses the second BWP to serve the The above-mentioned terminal equipment;

One of the beneficial effects of the embodiments of the present application is that according to the embodiments of the present application, it can be ensured that when the serving cell of the terminal equipment enters the energy-saving state, the energy-saving BWP is used to serve the terminal equipment. For example, when the cell enters the energy-saving state, terminal equipment in the IDLE/INACTIVE state can normally reside in the energy-saving cell; or, terminal equipment in the connected state can continue to transmit uplink and downlink data through the energy-saving cell. In this way, it is possible to avoid migrating the terminal equipment of the energy-saving cell to the adjacent cell, causing service interruption of the terminal equipment and increasing the load level of the adjacent cell.

The embodiments of the present application will be described below in conjunction with the drawings and specific implementation modes.

Embodiments of the first aspect

The embodiment of the present application provides a method for configuring a network energy-saving cell.

Figure 2 is a schematic diagram of a configuration method of a network energy-saving cell according to an embodiment of the present application. As shown in Figure 2, the method includes:

201. The network device sends first information to the terminal device. The first information is used to configure the second bandwidth part BWP to the serving cell of the terminal device, so that the network device uses the second BWP to serve the terminal device; wherein the network device runs the second BWP. The energy required for the second BWP is lower than the energy required for running the first BWP.

It is worth noting that the above Figure 2 only schematically illustrates the embodiment of the present application, but the present application is not limited thereto. For example, you can add some other operations or reduce some of them. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 2 above.

According to the method of the embodiment of the present application, it can be ensured that when the serving cell of the terminal device enters the energy-saving state, the energy-saving BWP is used to serve the terminal device. For example, when the cell enters the energy-saving state, terminal equipment in the IDLE/INACTIVE state can normally reside in the energy-saving cell; or, terminal equipment in the connected state can continue to transmit uplink and downlink data through the energy-saving cell. In this way, it is possible to avoid migrating the terminal equipment of the energy-saving cell to the adjacent cell, causing service interruption of the terminal equipment and increasing the load level of the adjacent cell.

In the above embodiment, the energy required by the network device when running the second BWP of the serving cell is lower than the energy required when running the first BWP of the same serving cell, that is, the power consumed by the network device when using the second BWP to transmit the peak rate The power consumed by the network device when transmitting the peak rate using the first BWP is lower than the power consumed by the network device when transmitting the unit data amount using the second BWP.

In the above embodiment, the network device consumes more power when running the second BWP of the serving cell than running the first BWP of the same serving cell. In order to run the second BWP, that is, to enable the second BWP to serve the terminal device, the network device configures the second BWP (i.e., energy-saving BWP) for the terminal device that has been configured or activated in the connection state of the first BWP (i.e., non-energy-saving BWP), Alternatively, a second BWP may be configured for a terminal device in a connected state that newly accesses the network, so that the second BWP serves the terminal device in a connected state. However, this application is not limited to this. The network device can also send the configuration of the second BWP through the system information of the cell, so that the idle or inactive terminal device resides in the second BWP of the cell, thereby making the second BWP service idle or Inactive terminal equipment.

In the above embodiment, the first BWP may be the initial BWP of the serving cell of the terminal device, or the dedicated BWP of the serving cell of the terminal device, and the present application is not limited thereto. In addition, the second BWP may be any BWP of the serving cell, including an initial BWP or a dedicated BWP, and the present application is not limited thereto. For example, the second BWP may be configured as a dedicated BWP of the serving cell of the terminal device. The first BWP and the second BWP may belong to the same serving cell of the terminal device, or may belong to different serving cells.

In some embodiments, the second BWP may be configured to a serving cell with lower traffic volume. For example, the second BWP is configured to a secondary cell of the terminal device in addition to the special cell (SpCell) and the physical uplink shared channel (PUCCH). SCell). If the current activated BWP of the serving cell of the terminal device is the second BWP, the serving cell can be identified by the terminal device as an energy-saving cell, that is, the serving cell has entered an energy-saving state for the terminal device.

In some implementations, the second BWP may be configured as the default BWP of the serving cell of the terminal device. That is to say, the energy-saving BWP (second BWP) and the default BWP may be the same BWP, that is, the BWP identifier is the same.

In this embodiment of the present application, the network device can implement a variety of energy saving methods through hardware or software, so that the second BWP consumes more power than the first BWP.

In some embodiments, network devices achieve energy savings in the time domain.

For example, the network device uses software to make the transmission period of the common signal of the second BWP longer than the transmission period of the common signal of the first BWP, so that the second BWP is more energy-saving than the first BWP. That is, the transmission cycle of the common signal of the second BWP is extended. The common signal here may be SS (synchronization signal), MIB (master information block), PBCH (physical broadcast channel), SIB1 (system information block), SI (system information), paging (paging), etc. This application is not limited to this. For example, the transmission period ssb-periodicity of the SSB associated with the second BWP is longer than the transmission period of the SSB associated with the first BWP. For another example, the period of the system information PDCCH (physical downlink control channel) search space of the second BWP is longer than that of the first BWP.

For another example, the network device stops the transmission of part of the downlink time unit of the second BWP through hardware or software, so that the second BWP is more energy-saving than the first BWP. That is, the network device stops the transmission of some frames, subframes, time slots, and symbols of the second BWP. For example, the network device stops the transmission of some frames, subframes, time slots, and symbols of the second BWP by turning off the radio frequency unit of the second BWP in part of the downlink time unit, while still transmitting all downlink frames, subframes, and symbols of the first BWP. Signals are sent on frames, time slots, or symbols.

For another example, the network device uses software not to send part of the signal of the second BWP, or to send a simplified common signal of the second BWP, so that the second BWP is more energy-saving than the first BWP. The common signals here can be SSB (Synchronization Signal Block), SS (Synchronization Signal), MIB (Master Information Block), PBCH (Physical Broadcast Channel), SIB1 (System Information Block), SI (System Information), Paging (Paging) ), etc., this application is not limited thereto. For example, the network device does not send the complete SSB of the second BWP, only sends the synchronization reference signal (SS) in the SSB of the second BWP, does not send the MIB or PBCH of the second BWP, and does not send SIB1 and SI, that is, only A simplified SSB of the second BWP is sent, and no system broadcast information is sent. For another example, the network device only sends the SSB of the second BWP and does not send SIB1 and SI, that is, it only sends the non-cell-defined SSB (NCD-SSB) related to the second BWP.

For another example, the network device uses software to configure the number of CSI-RS (channel state information reference signals) symbols configured in the second BWP to be less than the number of CSI-RS symbols configured in the first BWP, thereby achieving the second BWP to be more energy-saving than the first BWP. That is, compared with the first BWP, the second BWP configures fewer CSI-RSs. The network device may indicate the number of CSI-RS symbols configured in the second BWP to the terminal device through the CSI-RS resource configuration field in the BWP configuration.

In some embodiments, network devices achieve energy savings in the airspace.

For example, the network device uses hardware to make the number of transmitting antenna units of the second BWP smaller than the number of transmitting antenna units of the first BWP, so that the second BWP is more energy-saving than the first BWP. That is, compared with the first BWP, the second BWP has fewer transmitting antenna units, including related radio frequency channels, power amplifiers, etc. For example, the network device turns off part of the transmitting antenna units of the second BWP, including related radio frequency channels, power amplifiers, etc., without changing the settings of the transmitting antenna units of the first BWP. That is, the network uses part of the transmitting antenna units to transmit the first BWP. signal, use all transmitting antenna units to transmit the signal of the first BWP. In this way, the SSB of the second BWP and the SSB of the first BWP with the same index may no longer have a quasi-colocation relationship (QCL), and the network device can reconfigure the TCI (Transmission Configuration Indication) state related to the second BWP.

For another example, the network device uses hardware or software to make the number of transmit beams of the second BWP smaller than the number of transmit beams of the first BWP, so that the second BWP is more energy-saving than the first BWP. That is, compared with the first BWP, the number of transmission beams of the second BWP is smaller. For example, the network device turns off the radio frequency hardware corresponding to some beams of the second BWP, so that the number of beams actually transmitted by the second BWP is less than the number of beams of the first BWP. The beam of the second BWP may be the beam of the SSB related to the second BWP. In addition, the network device may indicate the beam actually sent by the second BWP to the terminal device through the system information block SIB1 of the second BWP or the ssb-PositionsInBurst field in the downlink BWP configuration.

For another example, the network device uses software to make the number of MIMO (Multiple Input Multiple Output) antenna ports of the second BWP smaller than the number of MIMO antenna ports of the first BWP, so that the second BWP is more energy-saving than the first BWP. That is, compared with the first BWP, the network device uses a smaller number of MIMO antenna ports to transmit the signal of the second BWP.

In some embodiments, network devices achieve energy savings in the frequency domain.

For example, the network device uses hardware or software to make the service bandwidth of the second BWP different from the service bandwidth of the first BWP, so that the second BWP is more energy-saving than the first BWP. That is, the service bandwidth of the second BWP is different from the service bandwidth of the first BWP. When the service bandwidth is larger and more energy-saving, the service bandwidth of the second BWP is greater than the service bandwidth of the first BWP; when the service bandwidth is smaller and more energy-saving, the service bandwidth of the second BWP is smaller than the service bandwidth of the first BWP. Wherein, the network device can indicate the bandwidth of the second BWP of the terminal device through the bandwidth configuration field in the BWP configuration.

In some embodiments, network devices achieve energy savings in the power domain.

For example, the network device uses software to make the transmission power of the second BWP lower than the transmission power of the first BWP, so that the second BWP is more energy-saving than the first BWP. That is, the transmission power of the second BWP is lower than the transmission power of the first BWP. For example, the transmit power ssb-PBCH-BlockPower of the SSB associated with the second BWP is lower than the transmit power of the SSB associated with the first BWP. The network device may indicate the transmit power of the second BWP of the terminal device through the cell configuration of the serving cell or the ssb-PBCH-BlockPower field in the BWP configuration.

Each of the above embodiments only illustrates the energy saving method, but the present application is not limited thereto, and appropriate modifications can also be made based on each of the above embodiments. For example, each of the above embodiments can be used alone, or one or more of the above embodiments can be combined.

In the embodiment of this application, the energy-saving state can be divided into different degrees, such as mild energy-saving BWP, moderate energy-saving BWP, deep energy-saving BWP, etc. For example, if the network device achieves energy saving in the time domain, the SSB sending period of the second BWP is 40ms during light energy saving, 80ms during moderate energy saving, and 80ms during deep energy saving. is 160ms. For another example, if the network equipment achieves energy saving in the airspace, the number of SSB transmission beams of the second BWP is 4 when it is light energy saving, it is 2 when it is medium energy saving, and it is 2 when it is deep energy saving. The number of SSB transmit beams is 1.

Through the above energy-saving methods, network equipment reduces the transmission of energy-saving BWP in the time domain, frequency domain, air domain or power domain, instead of stopping the signal transmission of energy-saving BWP, to ensure that network equipment can use energy-saving BWP to serve terminal equipment. For example, the terminal device in the IDLE/INACTIVE state can normally reside in the energy-saving BWP; or the terminal device in the connected state can perform uplink and downlink data transmission through the energy-saving BWP.

In some embodiments, the first BWP and the second BWP have no overlap in the frequency domain, as shown in FIG. 3 .

In the above embodiment, the network device can run the two BWPs of the serving cell at the same time, and the terminal devices of the serving cell do not need to change or switch to the second BWP at the same time. For example, when some terminal devices switch to the energy-saving BWP (second BWP) , other terminal devices can remain on the non-energy-saving BWP (first BWP). After all terminal equipment in the serving cell is changed or switched from the first BWP to the second BWP, the network equipment can stop running the first BWP, that is, stop sending and receiving signals on the first BWP. In the case where the network device runs the first BWP and the second BWP at the same time, the first BWP and the second BWP can be transmitted simultaneously by a set of hardware resources, or they are not transmitted simultaneously by the same set of hardware resources, but use different hardware resources respectively. Implement signal transmission of the first and second BWP.

In the above embodiment, the network device may not run the first BWP and the second BWP at the same time, that is, the network device uses different time domain resources to transmit the first BWP and the second BWP, as shown in FIG. 4 . For example, when the network device has only one set of hardware resources and cannot run the first BWP and the second BWP at the same time, do not run the first BWP and the second BWP at the same time. In this case, the network device uses different time domain resources to transmit the signal of the first BWP and the signal of the second BWP. The terminal equipment in the serving cell needs to change or switch to the second BWP at the same time, because after the network equipment starts transmitting the second BWP signal, the terminal equipment connected to the first BWP will be interrupted from service. Therefore, before the network device runs the second BWP, it is necessary to instruct the terminal device to change or switch to the second BWP to prevent service interruption of the terminal device. The network equipment can pre-set the switching time. When the switching time is reached, all terminal equipment in the serving cell will switch to the second BWP at the same time; or the network equipment can pre-set the energy-saving BWP switching time period. When the energy-saving BWP switching time period begins, the serving cell All terminal devices switch to the second BWP simultaneously and last for a preset time length (duration).

In some embodiments, the first BWP and the second BWP have overlapping portions in the frequency domain, as shown in FIGS. 5 and 6 .

In some implementations of the above embodiments, the frequency domain overlapping portions of the first BWP and the second BWP can be transmitted simultaneously.

In the above embodiment, the fact that the frequency domain overlapping portion can be transmitted simultaneously means that the first BWP and the second BWP will not cause interference to the terminal device when they are transmitted simultaneously. For example, the network device realizes energy saving in the time domain. The network device stops the transmission of some frames, subframes, time slots, and symbols of the second BWP and allows the first BWP to use all time domain resources for transmission. When the two BWPs are transmitted simultaneously, the terminal The device does not cause interference.

In the above embodiment, the terminal equipment in the serving cell does not need to change or switch to the second BWP at the same time. For example, when some terminal equipment switches to the second BWP, other terminal equipment can remain on the first BWP. After all terminal equipment in the serving cell is changed from the first BWP to or switched to the second BWP, the network equipment can stop operating the first BWP, that is, stop sending and receiving signals on the first BWP.

In the above implementation manner, the second BWP and the first BWP can realize signal transmission at the same time using a set of hardware resources, or different hardware resources can be used to realize the signal transmission of the first BWP and the second BWP respectively.

In other implementations of the above embodiments, the frequency domain overlapping parts of the first BWP and the second BWP cannot be transmitted simultaneously.

In the above embodiment, the fact that the frequency domain overlapping parts cannot be transmitted simultaneously means that when the first BWP and the second BWP are transmitted simultaneously, interference will be caused to the terminal equipment. For example, when the frequency domain overlapping part includes both the SSB of the second BWP and the SSB of the first BWP, the SSB of the first BWP uses part of the transmitting antenna units (for example, 96), while the SSB of the first BWP uses all the transmitting antenna units. (for example, 192), the first BWP and the second BWP cannot be transmitted at the same time, because the simultaneous transmission of two different SSBs will cause interference to the terminal equipment. The reason why the first BWP and the second BWP cannot be transmitted at the same time may also be due to other reasons, which are not limited by the embodiment of this application.

In the above embodiment, the network device does not run the first BWP and the second BWP at the same time, that is, the network device uses different time domain resources to transmit the first BWP and the second BWP. The network device can use the same set of hardware resources to run the first BWP. BWP and second BWP, as shown in Figure 5.

In the above embodiment, the network device needs to change from transmitting the signal of the first BWP to transmitting the signal of the second BWP. The terminal equipment needs to change or switch to the second BWP at the same time, because after the network equipment starts transmitting the second BWP signal, the terminal equipment connected to the first BWP will be interrupted from service. Therefore, before the network device runs the second BWP, it is necessary to instruct the terminal device to change or switch to the second BWP to prevent service interruption of the terminal device. In addition, the network equipment can also pre-set the switching time. When the switching time is reached, all terminal equipment in the serving cell will switch to the second BWP at the same time. Alternatively, the network equipment can pre-set the energy-saving BWP switching time period. When the energy-saving BWP switching time period starts, , all terminal equipment in the serving cell are switched to the second BWP at the same time and last for a preset time length (duration).

In some embodiments, the terminal device is not configured with BWP. In order to run the second BWP and enable the second BWP to serve the terminal device, the network device may configure the second BWP as the initial BWP or dedicated BWP of the serving cell of the terminal device.

In other embodiments, the first BWP is the BWP of the configured or activated serving cell of the terminal device. When the serving cell enters the energy-saving state, the network device may change or switch the serving cell of the terminal device from the first BWP to 2nd BWP. That is, the network device changes or switches the serving cell of the terminal device from a non-energy-saving BWP to an energy-saving BWP. Furthermore, if the serving cell leaves the energy-saving state, the serving cell of the terminal device can also be changed from a non-energy-saving BWP to or switched to an energy-saving cell.

The method of the embodiment of the present application will be described below with reference to specific scenarios.

In some embodiments, the network device does not need to pre-configure the second BWP. When the serving cell enters the energy-saving state, the network device reconfigures the parameters of the first BWP through the above-mentioned first information, so that the first BWP of the terminal device is changed to the second BWP. . For example, after the network enters energy saving, the currently activated BWP parameters of the terminal device are reconfigured through the RRC message, so that the currently activated BWP of the terminal device is switched from a non-energy-saving BWP to an energy-saving BWP.

In other embodiments, the network device pre-configures at least one second BWP for the serving cell of the terminal device through the first information and indicates the BWP identification (BWP ID) of the second BWP. For example, the network configures one or more energy-saving BWPs for each serving cell of the terminal device through an RRC message, and indicates the BWP identifier of the energy-saving BWP.

In the above embodiment, the network device can configure the second BWP of different energy-saving degrees for the terminal device, for example, a mild energy-saving BWP, a moderate energy-saving BWP, a deep energy-saving BWP, etc., and indicate the BWP of the BWP of different energy-saving degrees. logo. This enables flexible configuration of energy-saving BWPs.

Figure 7 is another schematic diagram of the configuration method of a network energy-saving cell according to an embodiment of the present application. As shown in Figure 7, in some implementations, the network device also sends second information (702) to the terminal device, indicating through the second information The terminal device switches from the first BWP to the second BWP, so that the terminal device activates the second BWP and deactivates the first BWP.

For example, the network device pre-configures at least one energy-saving BWP (second BWP) through an RRC message. When the serving cell enters the energy-saving state, the network device instructs the terminal device to switch from the non-energy-saving BWP (first BWP) to the energy-saving BWP (second BWP) through PDCCH (physical downlink control channel)/DCI (downlink control indication) signaling. ), including activating the energy-saving BWP (second BWP) and deactivating the non-energy-saving BWP (first BWP), so that the activated BWP of the serving cell of the current terminal device is the energy-saving BWP.

In the above embodiment, the second information may be scrambled by the Common Radio Network Temporary Identity (C-RNTI), and the network device may instruct one or a group of terminal devices to switch the serving cell from the first BWP to the second BWP through the second information. .

For example, PDCCH/DCI signaling uses at least 1 bit to indicate switching between energy-saving BWP (second BWP) and non-energy-saving BWP (first BWP). For example, "0" is used to indicate switching to energy-saving BWP (if the currently activated BWP is Non-energy-saving BWP).

In the above embodiment, the network device may also instruct the terminal device to switch at least one serving cell from the first BWP to the second BWP through the above second information, or instruct the terminal device to switch at least one group of serving cells from the first BWP to the second BWP. 2nd BWP.

For example, the network device instructs the terminal device to convert the BWPs of all serving cells into energy-saving BWPs, or instructs the terminal device to convert the BWPs of one or more groups of serving cells into energy-saving BWPs. For example, when configuring a serving cell to a certain serving cell group, the PDCCH/DCI signaling contains several bits, each of which indicates switching the serving cell of a specific serving cell group to an energy-saving BWP.

In the above embodiment, as shown in Figure 7, the network device may also send third information (703) to the terminal device, instructing the terminal device through the third information to switch the serving cell from the second BWP to the first BWP, so that the terminal device The device activates the first BWP and deactivates the second BWP.

For example, when the serving cell leaves the energy-saving state, the network device uses PDCCH (DCI) signaling to cause the terminal device to switch the serving cell from the energy-saving BWP (second BWP) to the non-energy-saving BWP (first BWP), including activating the non-energy-saving BWP. The energy-saving BWP (first BWP) and the deactivated energy-saving BWP (second BWP) make the activated BWP of the serving cell of the current terminal device a non-energy-saving BWP.

In the above embodiment, the third information may be scrambled by the Common Radio Network Temporary Identity (C-RNTI), and the network device may instruct one or a group of terminal devices to switch the serving cell from the second BWP to the first BWP through the third information. .

For example, PDCCH/DCI signaling uses at least 1 bit to indicate switching between an energy-saving BWP (second BWP) and a non-energy-saving BWP (first BWP). For example, "1" is used to indicate switching to a non-energy-saving BWP (if the BWP is currently activated). for energy saving BWP).

In the above embodiment, the network device may instruct the terminal device to switch at least one serving cell from the second BWP to the first BWP through the above third information, or instruct the terminal device to switch at least one group of serving cells from the second BWP to the first BWP. BWP.

For example, the network device instructs the terminal device to convert the energy-saving BWPs of all serving cells into non-energy-saving BWPs, or instructs the terminal device to convert the energy-saving BWPs of one or more groups of serving cells into non-energy-saving BWPs. For example, when configuring a serving cell to a certain serving cell group, the DCI signaling contains several bits, each of which indicates switching the serving cell of a specific serving cell group from an energy-saving BWP to a non-energy-saving BWP.

In the above embodiment, the first information is carried by the RRC message, and the second information and the third information are carried by the PDCCH/DCI signaling. However, the application is not limited to this. The first information, the second information and the third information are It can also be carried by other messages or signaling.

In the above embodiment, when all terminal devices in a serving cell activate the energy-saving BWP (second BWP), the network device can release the air interface resources and hardware resources of the non-energy-saving BWP (first BWP) to save energy. purpose of electricity.

In the above embodiment, since the energy-saving BWP has been configured in the RRC message in advance, the terminal device can prepare to receive the energy-saving BWP in advance, thereby saving preparation time when switching to the energy-saving BWP (second BWP).

As shown in Figure 8, in other embodiments, the network device also sends fourth information to the terminal device (802); through the fourth The information indicates or configures the first BWP switching time, so that the terminal device switches the serving cell from the first BWP to the second BWP when the first BWP switching time is reached.

The serving cell is switched from the second BWP to the first BWP at the time.

For example, the network device pre-configures at least one energy-saving BWP (second BWP) through an RRC message. When the current active BWP of the serving cell of the terminal device is a non-energy-saving BWP (first BWP), the network device configures an energy-saving BWP switching time (called the first BWP switching time) through RRC message or MAC CE signaling. Figure 9 is a schematic diagram of the first BWP switching time. As shown in Figure 9, when the first BWP switching time is reached, the terminal equipment switches the serving cell from the non-energy-saving BWP (first BWP) to the energy-saving BWP (second BWP), the service cell enters the energy-saving state. When the terminal device activates the energy-saving BWP (second BWP), the network device can also configure a non-energy-saving BWP switching time (called the second BWP switching time) through RRC message or MAC CE signaling. When the second BWP switching time is reached, When, the terminal device switches the serving cell from the energy-saving BWP to the non-energy-saving BWP (first BWP), and the serving cell leaves the energy-saving state.

However, the application is not limited to this. The first information, the fourth information and The fifth information may also be carried by other messages or signaling.

The BWP is switched to the second BWP and at the end of the duration the serving cell is switched from the second BWP to the first BWP.

For example, the network device pre-configures at least one energy-saving BWP (second BWP) and BWP switching time configuration through RRC messages. The BWP switching time configuration may be for the terminal device or for a specific serving cell. This application does not do this. limit. The BWP switching time configuration includes a BWP switching period and duration. Figure 10 is a schematic diagram of BWP switching time configuration.

One BWP switches to the second BWP.

In the above embodiment, the BWP timer may be specific to the serving cell, but the present application is not limited thereto.

For example, the network device configures at least one energy-saving BWP (second BWP) and a BWP timer for a specific serving cell in advance through an RRC message. Figure 11 is a schematic diagram of the BWP timer. As shown in Figure 11, if the preset conditions are met, the terminal device starts or restarts the BWP timer. When the BWP timer times out, the terminal device will serve the current BWP of the cell ( The non-energy-saving BWP (ie, the first BWP) is switched to the energy-saving BWP (the second BWP).
