[0002] Wireless communication technology has developed to the 5th generation communication technology, in which beamforming is widely used.

[0036] It should be understood that the specific implementation described herein is merely intended for the explanation of the present application and is not intended to limit the present application.
[0037] In the subsequent description, the suffixes such as "module", "component", or "unit" used to represent elements are merely for the convenience of the description of the present application, and have no specific meaning in itself, and thus, "module", "component", or "unit" can be mixedly used.
[0038] Figure 2 is a flowchart of a base station energy saving method provided by an embodiment of the present application, which can be applicable to the case where the base station enters an energy saving mode, and the method can be executed by a base station energy saving device, which is generally integrated in the base station, see Figure 2 , the method provided by the embodiment of the present application specifically includes the following steps:
[0039] Step 110, determining an energy saving mode.
[0040] The energy saving mode can be a state in which the base station processes signals according to different modes, for example, the base station can transmit or receive signals according to different powers in different energy saving modes, for example, the duration of the base station in the energy saving state is different in different energy saving modes, for example, the types of signals transmitted or received by the base station are different in different energy saving modes.
[0041] In the embodiment of the present application, the base station can determine the energy saving mode it enters, and the manner of determining the energy saving mode is not limited herein, for example, the base station enters different energy saving modes based on the load, enters different energy saving modes based on upper layer instruction control, enters different energy saving modes based on different channel states, enters different energy saving modes based on different quality of service requirements, and the like.
[0042] In step 120, the signal processing corresponding to the energy saving mode is performed.
[0043] Specifically, the base station can perform the corresponding signal processing according to the determined energy saving mode. It can be understood that different energy saving modes can configure different signal processing manners, and the base station can obtain the corresponding signal processing manner according to the corresponding energy saving mode after determining the corresponding energy saving mode, for example, in the first energy saving mode, the base station can neither receive nor transmit signals.
[0044] In the embodiment of the present application, by determining the energy saving mode and performing the corresponding signal processing according to the energy saving mode, the base station energy saving in different situations is realized, and the power consumption of the base station can be reduced under the premise of ensuring the communication quality.
[0045] Further, on the basis of the above-mentioned application embodiment, the energy saving mode includes at least one of the following: micro-sleep mode, light-sleep mode and deep-sleep mode.
[0046] In the embodiment of the present application, at least three energy saving modes can be set according to the duration length of the base station being turned off and the transmission type of the signal, and the duration of the base station being turned off can be divided into micro-sleep mode, light-sleep mode and deep-sleep mode in turn from short to long. It can be understood that the types of energy saving modes can not be limited to the above-mentioned modes, and the types of energy saving modes can be further refined based on the duration length of the base station being turned off and the transmission type of the signal.
[0047] Further, on the basis of the above-mentioned application embodiment, the time granularity of the duration of the energy saving mode includes at least one of the following: symbol level, millisecond level, ten-millisecond level, hundred-millisecond level, second level and minute level.
[0048] In the embodiment of the present application, the energy saving mode of the base station can be divided according to different time granularities of the duration, and different energy saving modes can have different time granularities of the duration. It can be understood that the duration of each energy saving mode can be one or more time granularities.
[0049] Figure 3 is a flowchart of a base station energy saving method provided by an embodiment of the present application, which is a specific embodiment based on the above-mentioned embodiment of the present application, and in which the signal processing of different energy saving modes is specified, as shown in Figure 3 The method provided by the embodiment of the present application specifically includes the following steps:
[0050] Step 210, determining an energy saving mode, wherein the energy saving mode includes at least one of the following: a micro-sleep mode, a light-sleep mode and a deep-sleep mode.
[0051] In the embodiment of the present application, the energy saving mode of the base station can include the micro-sleep mode, the light-sleep mode and the deep-sleep mode, and the base station can determine an energy saving mode in the micro-sleep mode, the light-sleep mode and the deep-sleep mode.
[0052] Step 220, in the case of the micro-sleep mode, stopping the transmission and / or reception of a first range signal, wherein the first range signal includes at least one of the following: a physical downlink control channel (PDCCH) signal, a physical downlink shared channel (PDSCH) signal and a physical uplink shared channel (PUSCH) signal.
[0053] Specifically, in the case where the base station determines the energy saving mode as the micro-sleep mode, the base station can stop transmitting the PDCCH signal and the PDSCH signal, and can also stop receiving the PUSCH signal.
[0054] Step 230, in the case of the light-sleep mode, stopping the transmission and / or reception of a second range signal, wherein the second range signal includes at least one of the following: the PDCCH signal, the PUSCH signal, a channel state information reference signal (CSI-RS) signal, the PUSCH signal and a channel sounding reference signal (SRS) signal.
[0055] In the embodiment of the present application, in the case where the base station enters the light-sleep mode, the base station stops transmitting the PDCCH signal, the PDSCH signal and the CSI-RS signal, and can also stop receiving the PUSCH signal and the SRS signal.
[0056] Further, in another embodiment, in the case of the light-sleep mode, a sparse period CSI-RS signal and / or a synchronization signal block (SSB) is transmitted.
[0057] Specifically, the base station in the light-sleep mode reduces the impact on the UE, and can also transmit a sparse period CSI-RS signal or SSB, and the transmission frequency of the sparse period can be less than the signal transmission frequency in the normal mode, for example, the sparse period can be 100ms or 200ms.
[0058] Step 240, in the case of deep sleep mode, turn off the sending of all downlink signals and turn off the receiving of all uplink signals.
[0059] Specifically, the base station can not transmit any downlink signals and not receive any uplink signals in the case of determining to enter the deep sleep mode.
[0060] Further, in another embodiment, in the case of deep sleep mode, send sparse period SSB or receive sparse period PRACH.
[0061] Specifically, the base station can transmit SSB or receive PRACH in sparse period in the case of determining the energy saving mode as deep sleep, wherein the signal transmission frequency or signal reception frequency in the sparse period can be less than the signal transmission or signal reception frequency of the base station in the normal mode, and the sparse period can be 100 ms or 200 ms.
[0062] Further, on the basis of the above application embodiment, the basis for determining the energy saving mode can include at least one of the following: beam load, cell load, traffic data volume, and traffic latency sensitivity.
[0063] In the embodiment of the present application, the base station can select an appropriate energy saving mode based on its own beam load, cell load, traffic data volume, and traffic latency sensitivity of the traffic carried.
[0064] Further, on the basis of the above application embodiment, determining the energy saving mode includes:
[0065] determining the energy saving mode as non-energy saving mode under a first preset condition, wherein the first preset condition includes at least one of the following: beam load greater than a first beam load threshold, cell load greater than a first cell load threshold, traffic data volume greater than a first traffic volume threshold, and traffic latency sensitivity as latency sensitive.
[0066] determining the energy saving mode as micro-sleep mode under a second preset condition, wherein the second preset condition includes at least one of the following: beam load less than or equal to the first beam load threshold and greater than a second beam load threshold, cell load less than or equal to the first cell load threshold and greater than a second cell load threshold, traffic data volume less than or equal to the first traffic volume threshold and greater than a second traffic volume threshold, and traffic latency sensitivity as latency insensitive.
[0067] determining the energy saving mode as a light sleep mode under a third preset condition, wherein the third preset condition comprises at least one of the following: the beam load is less than or equal to the second beam load threshold and greater than a third beam load threshold, the cell load is less than or equal to the second cell load threshold and greater than a third cell load threshold, the traffic data volume is less than or equal to the second traffic volume threshold and greater than a third traffic volume threshold, and the traffic latency sensitivity is latency insensitive;

[0069] In the embodiments of the present application, the energy saving mode of the base station can be determined according to the beam load, the cell load, the traffic data volume and the traffic latency sensitivity of the base station.
[0070] Specifically, when the beam load of the base station is greater than a first beam load threshold or the cell load of the base station is greater than a first cell load threshold, the traffic data volume of the base station is greater than a first traffic volume threshold, and the traffic latency sensitivity of the base station is latency sensitive, the energy saving mode of the base station is a non-energy saving mode when the base station satisfies at least one of the above conditions.
[0071] When the beam load of the base station is less than or equal to the first beam load threshold and greater than a second beam load threshold, the cell load of the base station is less than or equal to the first cell load threshold and greater than a second cell load threshold, the traffic data volume of the base station is less than or equal to the first traffic volume threshold and greater than a second traffic volume threshold, and the traffic latency sensitivity of the base station is latency insensitive, the energy saving mode of the base station can be a micro sleep mode when the base station satisfies at least one of the above conditions.
[0072] When the beam load of the base station is less than or equal to the second beam load threshold and greater than a third beam load threshold, the cell load of the base station is less than or equal to the second cell load threshold and greater than a third cell load threshold, the traffic data volume of the base station is less than or equal to the second traffic volume threshold and greater than a third traffic volume threshold, and the traffic latency sensitivity of the base station is latency insensitive, the energy saving mode of the base station is a light sleep mode when the base station satisfies at least one of the above conditions.
[0073] When the beam load of the base station is less than or equal to the third beam load threshold, the cell load of the base station is less than or equal to the third load threshold, the traffic data volume of the base station is less than or equal to the third traffic volume threshold, and the traffic latency sensitivity of the base station is latency insensitive, the energy saving mode of the base station is a deep sleep mode when the base station satisfies at least one of the above conditions.
[0074] In one example embodiment, when the base station is in power saving mode, it can consider to turn off some signal transmission, and the off state can last for several symbols, hundreds of milliseconds, seconds, or even minutes. In different off states, the power saving effect is different, the longer the duration, the better the power saving effect. However, when the base station is in power saving mode, the impact on the user equipment (UE) needs to be considered. Turning off different signal transmission or reception for different lengths of time will have different impacts on the UE.
[0075] Three off modes are defined for the base station:
[0076] 1. Micro-sleep: The duration can be several symbols, several milliseconds. During the off period, the base station can affect the scheduling of the UE. The base station can turn off the transmission of PDCCH, PDSCH, etc. and also turn off the reception of PUSCH, etc. In this state, the UE can perform one of the following activities: no monitoring of PDCCH, no transmission of uplink shared channel, no reporting of channel state information, no transmission of PUCCH (except for reporting L1-RSRP signal), clearing of HARQ buffer, deactivation of all bandwidth parts (BWP), and clearing of all uplink resources (which can include configured uplink grant resources, SPS resources, SR resources, etc.).
[0077] 2. Light sleep: The duration can be tens of milliseconds, hundreds of milliseconds. During the off period, the base station can affect the reception or transmission of beams of the UE. The base station can turn off the transmission of PDCCH, PDSCH, CSI-RS, SSB, etc. and also turn off the reception of PUSCH, SRS, etc. To reduce the impact on the UE, the base station can also transmit sparse CSI-RS, SSB, e.g. with a period of 100 ms, or receive sparse SRS. In this state, the UE can perform one of the following activities: no monitoring of PDCCH, no monitoring of CSI-RS or reception of sparse CSI-RS, no monitoring of SSB or reception of sparse SSB, no transmission of UL-SCH, no transmission of SRS or transmission of sparse SRS, no reporting of CSI, no transmission of PUCCH or transmission of sparse L1-RSRP, clearing of HARQ buffer, deactivation of all BWP, and clearing of all uplink resources (including configured uplink grant resources, SPS resources, SR resources, etc.).
[0078] 3. Deep sleep: the duration can be hundreds of milliseconds, seconds, minutes or even longer. During the off period, the base station can affect the UE connection, the UE can experience radio link failure, or cannot access the cell. The base station will turn off the transmission of all downlink signals and also turn off the reception of all uplink signals. In order to reduce the impact on the UE, the base station can also send sparse SSBs, for example, with a period of 200ms, or receive sparse PRACH. In this state, the UE can perform one of the following activities: no monitoring of PDCCH, no monitoring of CSI-RS or reception of sparse CSI-RS, no monitoring of SSB or reception of sparse SSB, no transmission of UL-SCH, no transmission of SRS, no CSI reporting, no transmission of PUCCH, empty HARQ buffer, deactivate all BWPs, empty all uplink resources (including configured uplink grant resources, SPS resources, SR resources, etc.).
[0079] The base station can consider the load of the cell when entering the above-mentioned off mode, for example:
[0080] 1. When the load of the beam or cell is heavy, the data volume of the carried service is large, and the service is time delay sensitive, the beam or cell will not be turned off
[0081] 2. When the load of the beam or cell is medium, the data volume of the carried service is small, and the service is not time delay sensitive, the beam or cell can consider micro sleep
[0082] 3. When the load of the beam or cell is light, the data volume of the carried service is small, and the service is not time delay sensitive, and the number of carried UEs is small, the beam or cell can consider light sleep
[0083] 4. When the load of the beam or cell is extremely light, and the number of carried UEs is extremely small or none, the beam or cell can consider deep sleep.
[0084] In the embodiments of the present application, the energy saving mode of the base station can also be referred to as a sleep state, an inactive state, a light load state, etc. The non-energy saving state of the base station can be a normal state, an active state, a heavy load state, etc.
[0085] Figure 4 is a flowchart of another base station energy saving method provided by the embodiments of the present application, which is a specific embodiment based on the above-mentioned embodiments of the present application. Referring to Figure 4 , the method provided by the embodiments of the present application specifically includes the following steps:
[0086] Step 310, determining an energy saving mode.
[0087] Step 320, performing signal processing corresponding to the energy saving mode.
[0088] Step 330, information indicating the energy saving mode.
[0089] In the embodiment of the present application, the base station can also indicate the energy saving mode entered by the terminal device, and the indication can include explicit indication or implicit indication. For example, the base station can indicate the energy saving mode entered by the terminal device through signaling, or in another example, the base station can implicitly indicate the energy saving mode entered by the terminal device without receiving feedback from the terminal device.
[0090] Further, based on the above-mentioned embodiment, the information indicating the energy saving mode includes at least one of the following:
[0091] The base station configures periodic signal resources for the terminal device to perform link recovery, beam failure detection, and candidate beam periodicity.
[0092] The base station configures periodic signal resources for the terminal device to perform wireless link monitoring.
[0093] In the embodiment of the present application, the base station can configure the signal resources of the terminal device to indicate the energy saving mode entered by the terminal device, which can include configuring periodic signal resources for the terminal device to perform link recovery, beam failure detection, and candidate beam periodicity, and can also include configuring periodic signal resources for the terminal device to perform wireless link detection.
[0094] Further, based on the above-mentioned embodiment, the signal resources include CSI-RS resources and synchronization signal block (SSB) resources.
[0095] Specifically, the signal resources configured by the base station to indicate the energy saving mode can be CSI-RS resources or SSB resources.
[0096] Further, based on the above-mentioned embodiment, the signal resources are configured based on a radio resource control (RRC) message.
[0097] Specifically, the base station can configure the signal resources for indicating the energy saving mode through an RRC message.
[0098] Further, based on the above-mentioned embodiment, the configuration parameters of the signal resources include at least two of the following: a start time, a duration, and an end time.
[0099] In the embodiment of the present application, when the base station configures the signal resources for the terminal device, the base station can use configuration parameters for configuration, which can include a start time and an end time, can also include a start time and a duration, and can also include an end time and a duration, etc.
[0100] Figure 5 is a flowchart of another base station energy saving method provided by the embodiment of the present application, which is a specific embodiment based on the above-mentioned embodiment.Figure 5 The method provided by the embodiments of the present application specifically comprises the following steps:
[0101] Step 410, determining the energy saving mode.
[0102] Step 420, performing signal processing corresponding to the energy saving mode.
[0103] Step 430, indicating the signal resource detected by the terminal device under the preset condition.
[0104] In the embodiments of the present application, the base station can indicate the terminal device to check the signal resource under the preset condition, and the indication can comprise the indication of the signal resource. It can be understood that the preset condition can be predefined by a protocol, or indicated by the base station, or configured by upper signaling. The type of the signal resource checked by the device under the indication of different preset conditions can be different.
[0105] Further, on the basis of the above-mentioned embodiments, the signal resource is used for wireless link monitoring, and the signal resource comprises: periodic CSI-RS resource or SSB resource, semi-static CSI-RS resource or SSB resource, and aperiodic CSI-RS resource or SSB resource.
[0106] Specifically, the signal resource detected by the terminal under the preset condition indicated by the base station can be used for detecting the wireless link, and the type of the signal resource can be periodic CSI-RS resource, periodic SSB resource, semi-static CSI-RS resource, semi-static SSB resource, aperiodic CSI-RS resource, or aperiodic SSB resource.
[0107] Further, on the basis of the above-mentioned embodiments, the preset condition comprises at least one of the following: turning off dense CSI-RS resource or SSB resource, the base station entering the energy saving state, the base station indicating the terminal device to take effect CSI-RS resource or SSB resource, the terminal device detecting that the base station enters the energy saving state, the terminal device detecting that the dense CSI-RS resource or SSB resource is invalid, the terminal device detecting the sparse CSI-RS or SSB signal, the base station turning on the dense CSI-RS resource or SSB resource, the base station entering the non-energy saving state, the base station indicating the terminal device to invalidate the CSI-RS resource or SSB resource, the terminal device detecting that the base station enters the non-energy saving state, and the terminal device detecting that the dense CSI-RS resource or SSB resource is valid.
[0108] In the embodiments of the present application, the terminal device detects one or more preset conditions of the signal resource, which can include one or more of the following: the base station turns off dense CSI-RS resources, the base station turns off dense SSB resources, the base station enters an energy-saving state, the base station instructs the terminal device to activate CSI-RS resources, the base station instructs the terminal device to activate SSB resources, the terminal device detects that the base station enters an energy-saving mode, the terminal device detects that dense CSI-RS resources are deactivated, the terminal device detects that dense SSB resources are deactivated, the terminal device detects sparse CSI-RS resources, the terminal device detects sparse SSB resources, the base station turns on dense CSI-RS resources or SSB resources, the base station enters a non-energy-saving state, the base station instructs the terminal device to deactivate CSI-RS resources or SSB resources, the terminal device detects that the base station enters a non-energy-saving state, and the terminal device detects that dense CSI-RS resources or SSB resources are activated. The terminal device can detect the same or different signal resources under different preset conditions, thereby cooperating with the energy-saving mode of the base station.
[0109] In an exemplary embodiment, when the base station decides to turn off the transmission of some signals, the off state can last for tens of milliseconds, hundreds of milliseconds, and the base station can enter an energy-saving mode by turning off CSI-RS or SSB signals. Because the CSI-RS or SSB signals are turned off, beam tracking, beam training, and beam management based on these signals will be affected. If the off time exceeds a certain time, the UE can experience beam failure, that is, the UE cannot find a suitable serving beam. If beam failure occurs, the UE triggers a beam recovery process to find a suitable beam. If no suitable beam is found, the UE selects any beam and initiates a RACH process on the PRACH resource corresponding to the beam. If the RACH process is unsuccessful, the UE returns to the IDLE state until a radio link failure is triggered. It can be seen that if the base station turns off the CSI-RS or SSB signal for a long time, it will cause the UE to perform complex operations. To avoid the above problems, the following methods can be used:
[0110] Method one: when the base station turns off the CSI-RS or SSB signal, or the base station enters an energy-saving state, the base station will send a certain CSI-RS or SSB. The base station configures periodic CSI-RS or SSB resources for link recovery, monitoring beam failure, and candidate beams for the UE, such as signal 1, and the period of these signals is dense. The UE monitors whether the beam can serve the UE based on these signals. If the base station turns off the transmission of these signals, in order to prevent the UE from experiencing beam failure, such as Figure 6, the base station will send certain CSI-RS or SSB, such as signal 2, which are more sparse in periodicity. The frequency domain resources of signal 2 are the same as signal 1. The starting time of signal 2 is the same as the starting time of signal 1.
[0111] The time of certain CSI-RS or SSB (such as signal 2) is also specified by the base station, including the starting time, duration, or end time.
[0112] If the base station does not inform the UE of the change of CSI-RS or SSB, the UE will continue to monitor the CSI-RS or SSB according to the unchanged configuration.
[0113] If the base station informs the UE of the change of CSI-RS or SSB, the UE will no longer monitor the unchanged CSI-RS or SSB, and will monitor the changed CSI-RS or SSB according to the indication of the base station.
[0114] Method two: the base station indicates the resources of the CSI-RS or SSB that need to be detected under certain conditions. The base station configures the resources of the CSI-RS or SSB, which are used for link recovery, monitoring beam failure, candidate beam CSI-RS or SSB. These signals can be periodic CSI-RS or SSB, semi-static CSI-RS or SSB, and aperiodic CSI-RS or SSB. The resources configured by the base station include the frequency domain resources and time domain resources of these signals. If the base station configures periodic CSI-RS and SSB, the configuration also includes the starting time and period.
[0115] The configuration or transmission of these signals is associated with the above-mentioned certain conditions. The configuration of these signals is associated with the energy saving state. For example, when the base station enters the energy saving state, the period of the CSI-RS or SSB associated with the condition is longer.
[0116] When a certain condition is reached, the base station will send these CSI-RS or SSB signals, and the UE will also detect beams based on these signals.
[0117] These conditions can include the base station turning off dense CSI-RS or SSB resources, the base station entering the energy saving state, the energy saving state, the base station indicating the CSI-RS or SSB resources that the UE needs to activate, the UE detecting that the base station enters the energy saving state, the UE detecting that the dense CSI-RS or SSB signal is invalid, or the UE detecting the sparse CSI-RS or SSB signal, etc.
[0118] If the UE knows that a certain condition has been reached, the UE will no longer monitor the CSI-RS or SSB under other conditions, but will monitor the CSI-RS or SSB corresponding to the condition.
[0119] The base station indicates the resources of CSI-RS or SSB that do not need to be detected under certain conditions. When a certain condition is reached, the base station will not send these CSI-RS or SSB signals, and the UE will also not detect beams based on these signals. The condition can be that the base station turns on dense CSI-RS or SSB resources, the base station enters a non-energy-saving state, the base station indicates that the UE invalidates or deactivates the CSI-RS or SSB resources, the UE detects that the base station enters an active state, the UE detects that the dense CSI-RS or SSB signals are valid, etc.
[0120] When a certain condition is reached, the base station will stop sending these CSI-RS or SSB signals, and the UE will also no longer detect beams based on these signals.
[0121] The base station configures the resources of CSI-RS or SSB can be configured by RRC message, the RRC message can be RRCReconfiguration, RRCSetup, RRCResume, etc. The resource can also be broadcast by system information.
[0122] In an exemplary embodiment, when the base station decides to turn off the transmission of some signals, the off state can last for hundreds of milliseconds, several seconds, and the CSI-RS or SSB signal can be turned off, that is, the base station enters an energy-saving mode. Since the CSI-RS or SSB signal is turned off, the radio link monitoring based on these signals will be affected, and if the off time exceeds a certain time, the UE can experience radio link failure, that is, the UE's radio link cannot be maintained. If radio link failure occurs, the UE will trigger RRC reestablishment, or the UE returns to IDLE state. It can be seen that if the base station turns off the CSI-RS or SSB signal for a long time, it will cause the UE to lose connection.
[0123] To avoid the above problems, possible methods are:
[0124] Method one: when the base station wants to turn off the CSI-RS or SSB signal, or the base station wants to enter an energy-saving state, the base station will send a certain CSI-RS or SSB. The base station will configure the UE with CSI-RS or SSB resources for radio link monitoring, such as signal 1, and the period of these signals is dense. The UE monitors whether the serving cell can serve the UE based on these signals. If the base station wants to turn off the transmission of these signals, in order to prevent the UE from experiencing radio link failure, such as Figure 7, the base station will send certain CSI-RS or SSB, such as signal 2, the periodicity of these signals is more sparse. The frequency domain resources of signal 2 are consistent with signal 1. The starting time of signal 2 is the sending time of signal 1. The time of certain CSI-RS or SSB (such as signal 2) is specified by the base station, including the starting time, the duration, or the end time.
[0125] Method two: the base station indicates the resources of CSI-RS or SSB that need to be detected under certain conditions. The base station configures the resources of CSI-RS or SSB, which are CSI-RS or SSB for radio link monitoring. These signals can be periodic CSI-RS or SSB, semi-static CSI-RS or SSB, or aperiodic CSI-RS or SSB. The resources configured by the base station include the frequency domain resources and time domain resources of these signals. If the base station configures periodic CSI-RS and SSB, the configuration also includes the starting time and the period.
[0126] The configuration or sending of these signals is associated with certain conditions. The configuration of these signals is associated with the energy saving state. For example, a certain condition is when the base station enters the energy saving state, and the periodicity of the CSI-RS or SSB associated with the condition is longer.
[0127] When a certain condition is reached, the base station will send these CSI-RS or SSB signals, and the UE will also detect the radio link based on these signals.
[0128] The condition can include the base station turning off the dense CSI-RS or SSB resources, the base station entering the energy saving state, the energy saving state, the base station indicating the CSI-RS or SSB resources that the UE validates or activates, the UE detecting that the base station enters the energy saving state, the UE detecting that the dense CSI-RS or SSB signal is invalid, or the UE detecting the sparse CSI-RS or SSB signal, etc.
[0129] The base station indicates the resources of CSI-RS or SSB that do not need to be detected under certain conditions. When a certain condition is reached, the base station will not send these CSI-RS or SSB signals, and the UE will also not detect the beams based on these signals. The condition can be that the base station turns on the dense CSI-RS or SSB resources, the base station enters the non-energy saving state, the base station indicates the CSI-RS or SSB resources that the UE invalidates or deactivates, the UE detects that the base station enters the active state, the UE detects that the dense CSI-RS or SSB signal is valid, etc.
[0130] When a certain condition is reached, the base station will stop sending these CSI-RS or SSB signals, and the UE will also no longer detect the beams based on these signals.
[0131] The base station configures the resource of the CSI-RS or the SSB can be configured by an RRC message, and the RRC message can be an RRCReconfiguration, an RRCSetup, an RRCResume or the like. The resource can also be broadcast by system information.

[0147] Figure 9 is a flowchart of a base station energy saving method provided by an embodiment of the application. The embodiment of the application is a specific embodiment based on the above-mentioned application embodiment. Referring to Figure 9 , the method provided by the embodiment of the application specifically includes the following steps:
[0148] Step 610, determining an energy saving mode.
[0149] Step 620, performing signal processing corresponding to the energy saving mode.
[0150] Step 630, enabling the terminal device to detect the energy saving mode through an enabling indication.
[0151] In the embodiments of the present application, the base station can send an enabling indication to the terminal device, and the terminal device can detect the energy saving mode of the base station after receiving the enabling indication.
[0152] Further, in one embodiment, the terminal device is enabled to determine the energy saving mode of the base station based on detecting the CSI-RS resource or the SSB resource through the RRC message.
[0153] In the embodiments of the present application, the base station can send an RRC message to the terminal device, so that the terminal device can detect the CSI-RS resource or the SSB resource to determine the energy saving mode of the base station.
[0154] Further, in another embodiment, the terminal device is enabled to determine the energy saving mode of the base station based on detecting the CSI-RS resource or the SSB resource through the system information.
[0155] Specifically, the base station can also send system information to the terminal device, and the terminal device can detect the CSI-RS resource or the SSB resource after receiving the terminal device, and can determine the energy saving mode of the base station through the detection result of the CSI-RS resource or the SSB resource.
[0156] Further, on the basis of the above-mentioned application embodiments, the enabling indication carries a threshold value of the energy saving mode, and the threshold value includes at least one of the following: time period information, signal detection quantity maximum threshold value, and signal detection quantity minimum threshold value.
[0157] In the embodiments of the present application, the enabling indication can carry a threshold value for detecting the energy saving mode, which can be specifically time period information, signal detection quantity maximum threshold value N1, signal detection quantity minimum threshold value N2, and the like. The terminal device can detect the CSI-RS resource or the SSB resource based on the above-mentioned threshold value, and when the resource detection result meets the above-mentioned threshold value, the corresponding energy saving mode of the base station can be determined, wherein the enabling indication can specifically include an RRC message or system information, and the like.
[0158] In one exemplary embodiment, the UE can detect the signal resource based on the RRC message or the system information sent by the base station, so that the UE can determine the energy saving mode entered by the base station. Specifically, the way for the UE to detect the energy saving mode of the base station can include the following methods.
[0159] Method one: the UE cannot detect the CSI-RS or SSB signal. The base station enables the UE to determine the energy saving state of the base station through the RRC message or the system information. If it is enabled, the UE can determine the energy saving state of the base station by detecting the CSI-RS or SSB signal. The base station can also configure the threshold value of the energy saving state through the RRC configuration or the system information broadcast, for example, time information and upper critical N value.
[0160] The base station configures periodic CSI-RS or SSB resources for link recovery, monitoring beam failure, candidate beam, the periodicity of these signals is dense. UE periodically detects the quality of these signals. If UE cannot detect N signals in a period of time, or UE cannot detect N signals continuously in a period of time, UE can consider that the base station no longer transmits these signals, and the base station enters the energy saving state. The UE will detect the CSI-RS or SSB associated with the energy saving state.
[0161] For example: UE cannot detect N1 signals S1 in a period of time 1, UE considers that the base station enters the light sleep state. UE will detect the signal S2 associated with it, such as sparse CSI-RS or SSB.
[0162] UE cannot detect N2 signals S2 in a period of time 2, UE considers that the base station enters the deep sleep state. UE will detect the signal S3 associated with it, such as more sparse CSI-RS or SSB.
[0163] The base station configures CSI-RS or SSB resources for wireless link monitoring, the periodicity of these signals is dense. UE periodically detects the quality of these signals. If UE cannot detect N signals in a period of time, or UE cannot detect N signals continuously in a period of time, UE can consider that the base station no longer transmits these signals, and the base station enters the energy saving state. In the energy saving state, the UE will detect the CSI-RS or SSB associated with it.
[0164] For example: UE cannot detect N1 signals S1 in a period of time 1, UE considers that the base station enters the deep sleep state. UE will detect the signal S2 associated with it, such as sparse CSI-RS or SSB.
[0165] Method two: UE detects CSI-RS or SSB signal. The base station enables UE to judge the energy saving state of the base station through RRC message or system information. If enabled, UE can judge the energy saving state of the base station by detecting CSI-RS or SSB signal. The base station can also configure the threshold value of the energy saving state through RRC configuration or system information broadcast, such as time information, lower threshold N value.
[0166] The base station configures periodic CSI-RS or SSB resources for link recovery, monitoring beam failure, candidate beam in energy saving state, the periodicity of these signals is sparse. The base station configures periodic CSI-RS or SSB resources for link recovery, monitoring beam failure, candidate beam in non-energy saving state, the periodicity of these signals is dense.
[0167] If the UE detects N signals in a period of time, or the UE continuously detects N signals in a period of time, the UE can consider that the base station sends these signals, and the base station enters the energy saving or non-energy saving state. In the energy saving or non-energy saving state, the UE detects the CSI-RS or SSB associated therewith.
[0168] For example: when the UE detects N1 signals S1 in a period of time 1, the UE considers that the base station enters the light sleep state. The UE detects the signals S1 associated therewith, such as dense CSI-RS or SSB.
[0169] When the UE detects N2 signals S2 in a period of time 2, the UE considers that the base station enters the non-energy saving state. The UE detects the signals S2 associated therewith, such as dense CSI-RS or SSB.
[0170] The base station configures the CSI-RS or SSB resources for wireless link monitoring in the energy saving state, and the period of these signals is sparse. The base station configures the CSI-RS or SSB resources for wireless link monitoring in the non-energy saving state, and the period of these signals is dense.
[0171] If the UE detects N signals in a period of time, or the UE continuously detects N signals in a period of time, the UE can consider that the base station sends these signals, and the base station enters the energy saving or non-energy saving state. In the energy saving or non-energy saving state, the UE detects the CSI-RS or SSB associated therewith.
[0172] For example: when the UE detects N1 signals S1 in a period of time 1, the UE considers that the base station enters the non-energy saving state. The UE detects the signals S1 associated therewith, such as dense CSI-RS or SSB.
[0173] Figure 10 is a flowchart of another base station energy saving method provided by the embodiment of the application, which is a specific embodiment based on the above-mentioned application embodiment. Referring to Figure 10 The method provided by the embodiment of the application specifically includes the following steps:
[0174] Step 710, determining an energy saving mode.
[0175] Step 720, performing primary and secondary cell PScell energy saving in the case that the terminal device is configured with dual connectivity.
[0176] In the embodiment of the application, when the terminal device is configured with dual connectivity, the base station can take corresponding processing on the primary and secondary cells when the base station adopts the energy saving mode, so that the primary and secondary cells PScell realize energy saving.
[0177] Further, on the basis of the above application examples, the power saving of the primary and secondary cells PScell is performed, including at least one of the following:
[0178] The primary and secondary cells are deactivated by MAC CE or DCI signaling; the primary and secondary cells are activated by MAC CE or DCI signaling.
[0179] In the embodiments of the present application, the method for controlling the power saving of the primary and secondary cells can include activating or deactivating the primary and secondary cells by signaling, where the signaling can be specifically MAC CE or DCI signaling.
[0180] Further, on the basis of the above application examples, the MAC CE or DCI instruction carries at least one of the following information: cell identifier, deactivation indication bit, time information, activation indication bit.
[0181] In an exemplary embodiment, when the UE is configured with dual connectivity, if the base station wants to take power saving measures on the PSCell, the PScell needs to close some services, and the power saving of the PSCell can be controlled, including the following methods:
[0182] Method one: the PSCell is deactivated by MAC CE or DCI. The MAC CE or DCI can carry the cell identifier, deactivation indication bit, time information, etc. The cell identifier can be the PSCell identifier or index of the UE. The deactivation indication bit can be an indication bit of whether to deactivate the PSCell, for example, the indication bit is 1 bit, and the setting of the 1 bit to 1 indicates that the base station deactivates the state. The time information can include: start time, duration, or end time. The UE activates the PScell after a period of time after receiving the MAC CE or DCI, and the information carried by the MAC CE or DCI takes effect. The effective time, duration, or end time can also be carried in the time information.
[0183] Method two: the PSCell is activated by MAC CE or DCI. The MAC CE or DCI is sent by the MCG. The MAC CE or DCI can carry the cell identifier, activation indication bit, time information, etc. The cell identifier can be the PSCell identifier or index of the UE. The activation indication bit can be an indication bit of whether to activate the PSCell, for example, the indication bit is 1 bit, and the setting of the 1 bit to 1 indicates that the base station activates the state. The time information can include: start time. The UE activates the PScell after a period of time after receiving the MAC CE or DCI, and the information carried by the MAC CE or DCI takes effect. The effective time can also be carried in the time information.
[0184] Further, on the basis of the above application embodiment, further comprising: sending a simplified system information block SIB, wherein the simplified SIB comprises cell access information.
[0185] In the embodiment of the present application, when the base station sends a system information block (SIB), it will consume more power, but if the SIB is not sent, it will cause the UE moving to the coverage to be unable to camp on. In order to reduce power consumption, the base station can send a simplified SIB, which only provides cell access information.
[0186] Further, on the basis of the above application embodiment, the cell access information comprises at least one of the following: PLMN identifier, TAC identifier, reserved identifier, PRACH configuration, SIB1 scheduling information.
[0187] Specifically, the PLMN identifier can be the identifier information of a public land mobile network (PLMN), the TAC identifier can be a type allocation code (TAC), the PRACH configuration can be configuration information of a physical random access channel (PRACH), the SIB1 scheduling information can be a scheduling block carrying cell selection information, and the reserved identifier can be a reserved identifier bit, which can be used to identify other custom information.
[0188] In an exemplary embodiment, in order to balance the energy saving of the base station and keep the UE moving to the coverage to camp on, the base station can adopt the following method:
[0189] The base station sends a simplified SIB, for example, a simplified SIB1, which only provides access information of the cell, for example, a PLMN identifier, a TAC identifier, a reserved identifier, and the configuration of a PRACH (including frequency domain and time delay resources), and the like. The resource of a certain PRACH can be associated with a conventional SIB1, or the resource of a certain PRACH is associated with the function of waking up the base station. The simplified SIB1 can also provide scheduling information of the conventional SIB1, for example, a sending time, and the like. However, the cell or initialBWP does not provide the configuration of a PDCCH or the configuration of channels such as a PUSCH and a PDSCH. A UE selects the cell, can obtain the simplified SIB1, and can determine whether the cell meets the condition of camping by using the access information. If the condition is met, the UE camps. When the UE wants to initiate a service or select to camp in the cell, the UE can initiate a preamble according to the configuration. However, the UE does not monitor a PDCCH corresponding to a RAR. After the base station receives the preamble, the base station considers that there is a UE camping in the cell, and the base station sends a conventional SIB1. The UE re-receives the SIB1, and selects whether to camp in the cell or initiate a service according to the configuration.
