Description

[Technical Field]

[0001] The present application relates to the technical field of wireless communication, and in particular to a base station energy saving method, a base station, a terminal device, and a storage medium. [Background technology]

[0002] Wireless communication technology has already evolved into fifth-generation communication technology, in which beamforming is widely applied. Here, beamforming uses many micro- or millimeter-order antenna sensors to form a rectangular array, and through human intervention, adjusts the parameters of the antenna basic units in the array and the different transmission times of the signals of each antenna sensor, forming a concentrated and directed electromagnetic wave beam transmission with stronger power, so that the signal obtained by the receiver can achieve optimal results.

[0003] Referring to FIG. 1, in network deployment, for a certain area, not only is there cell coverage in the area, but there is also beam coverage. First, people generally focus on the various advantages brought by 5G communication technology, such as higher speeds, wider bandwidths, lower latency, and higher connection density, while ignoring the costs associated with high performance. With the development of 5G communication technology, the problem of high base station power consumption is gradually becoming more prominent, and electricity bills have become a significant portion of network operation costs. How to reduce base station power consumption has become an urgent issue. The main reason for the significant increase in base station power consumption in 5G communication technology is the increase in the number of antennas. 5G base stations generally use matrix antennas, which realize beamforming to support more users and cover a larger area. However, the rapid increase in the number of antennas in 5G base stations also leads to a rapid increase in power consumption. For current operators, how to reduce base station power consumption while ensuring communication quality has become an urgent issue to be resolved.

[0011] It should be understood that the specific examples described herein are for purposes of interpretation only and are not intended to limit the present application.

[0012] In the following description, the use of suffixes such as "module," "component," or "unit" to denote elements is merely for the purpose of contributing to the explanation of the present application and has no specific meaning in itself. Therefore, "module," "component," or "unit" can be used interchangeably.

[0013] FIG. 2 is a flowchart of a base station energy saving method according to an embodiment of the present application. The embodiment of the present application is applied when a base station enters an energy saving mode, and the method can be performed by a base station energy saving device, which is generally integrated in a base station. Referring to FIG. 2, the method according to the embodiment of the present application specifically includes the following steps:

[0014] In step 110, the energy saving mode is determined. Here, the energy saving mode may be a state in which the base station performs signal processing according to different modes, for example, in different energy saving modes, the base station can transmit and receive signals according to different powers, for example, the duration of the base station energy saving state is different in different energy saving modes, and further, for example, the types of signals transmitted and received by the base station are different in different energy saving modes.

[0015] In an embodiment of the present application, the base station can determine the energy saving mode to enter, and the manner of determining the energy saving mode to enter is not limited thereto, for example, entering different energy saving modes based on the load of the base station, entering different energy saving modes based on upper layer command control, entering different energy saving modes based on different channel conditions, entering different energy saving modes based on different service quality requirements, etc.

[0016] In step 120, signal processing corresponding to the energy saving mode is performed. Specifically, the base station can perform corresponding signal processing according to the determined energy saving mode, and can set different signal processing methods according to different energy saving modes. After the base station determines the corresponding energy saving mode, it can obtain the corresponding signal processing method according to the corresponding energy saving mode. For example, it can be understood that in the first energy saving mode, the base station does not need to transmit or receive signals.

[0017] The embodiments of the present application determine an energy saving mode and perform corresponding signal processing according to the energy saving mode, thereby realizing energy saving in the base station in different cases and reducing the power consumption of the base station while ensuring communication quality.

[0018] Furthermore, based on the embodiment of the above application, the energy saving mode includes at least one of a micro sleep mode, a light sleep mode, and a deep sleep mode.

[0019] In the embodiments of the present application, at least three types of energy saving modes can be set according to the duration of time that the base station is off and the type of signal transmission, and can be divided into micro sleep mode, light sleep mode and deep sleep mode in order of the shortest duration of time that the base station is off. It can be understood that the types of energy saving modes are not limited to the above modes, and can be further subdivided based on the duration of time that the base station is off and the type of signal transmission.

[0020] Furthermore, based on the embodiment of the above application, the time granularity of the duration of the energy saving mode includes at least one of the order of symbols, the order of milliseconds, the order of tens of milliseconds, the order of hundreds of milliseconds, the order of seconds, and the order of minutes.

[0021] In the embodiments of the present application, the base station energy saving modes can be divided according to different time granularities of duration, and it can be understood that different energy saving modes may have different time granularities of duration, and the duration of each energy saving mode may have one or more time granularities.

[0022] FIG. 3 is a flowchart of a base station energy saving method according to an embodiment of the present application. The embodiment of the present application is implemented based on the embodiment of the above application. In the embodiment of the present application, signal processing of different energy saving modes is implemented. Referring to FIG. 3, the method according to the embodiment of the present application specifically includes the following steps:

[0023] In step 210, an energy saving mode is determined, where the energy saving mode includes at least one of a micro sleep mode, a light sleep mode, and a deep sleep mode.

[0024] In an embodiment of the present application, the base station energy saving mode may include a micro sleep mode, a light sleep mode and a deep sleep mode, and the base station can determine the energy saving mode from the micro sleep mode, the light sleep mode and the deep sleep mode.

[0025] In step 220, when in microsleep mode, stop transmitting and / or receiving first range signals, where the first range signals include at least one of a physical downlink control channel PDCCH signal, a physical downlink shared channel PDSCH signal, and a physical uplink shared channel PUSCH signal.

[0026] Specifically, when the base station determines that the energy saving mode is the micro-sleep mode, the base station may stop transmitting the PDCCH signal and the PDSCH signal, and may stop receiving the PUSCH signal.

[0027] In step 230, if in light sleep mode, stop transmitting and / or receiving second range signals, where the second range signals include at least one of a PDCCH signal, a PUSCH signal, a Channel State Information-Reference Signal (CSI-RS), a PUSCH signal, and a Channel Sounding Reference Signal (SRS).

[0028] In an embodiment of the present application, when a base station enters light sleep mode, the base station may stop transmitting a PDCCH signal, a PDSCH signal, and a CSI-RS, and may also stop receiving a PUSCH signal and a channel sounding reference signal (SRS).

[0029] Furthermore, in another embodiment, in the light sleep mode, the CSI-RS and / or synchronization signal block SSB are transmitted at sparse intervals.

[0030] Specifically, in light sleep mode, the base station may transmit CSI-RS or SSB with a sparse period to reduce the impact on the UE, and the transmission frequency of the sparse period may be smaller than the transmission frequency of the signal in normal mode; for example, the sparse period may be 100 ms or 200 ms.

[0031] In step 240, if in deep sleep mode, all downstream transmissions and all upstream receptions are turned off.

[0032] Specifically, when the base station determines to enter the deep sleep mode, it does not need to transmit any downlink signals and does not need to receive any uplink signals.

[0033] Furthermore, in another embodiment, in the deep sleep mode, a sparsely-period SSB is transmitted or a sparsely-period PRACH is received.

[0034] Specifically, when the base station determines that the energy saving mode is deep sleep, it can transmit SSB or receive PRACH in a sparse period, where the signal transmission frequency or signal reception frequency of the sparse period may be smaller than the signal transmission or signal reception frequency of the base station in normal mode, and the sparse period may be 100 ms or 200 ms.

[0035] Furthermore, based on the embodiment of the above application, the basis for determining the energy saving mode may include at least one of beam load, cell load, traffic data volume, and traffic delay sensitivity.

[0036] 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 delay sensitivity of the traffic it carries.

[0037] Furthermore, based on the embodiment of the above application, determining the energy saving mode can be: determining that the energy saving mode is a non-energy saving mode under a first preset condition including at least one of: a beam load is greater than a first beam load threshold; a cell load is greater than a first cell load threshold; a traffic data volume is greater than a first traffic volume threshold; and a traffic delay sensitivity is delay sensitive; determining that the energy saving mode is a microsleep mode under second preset conditions including at least one of: a beam load being less than or equal to the first beam load threshold and greater than a second beam load threshold; a cell load being less than or equal to the first cell load threshold and greater than a second cell load threshold; a traffic data volume being less than or equal to the first traffic volume threshold and greater than a second traffic volume threshold; and a traffic delay sensitivity being delay insensitive; determining that the energy saving mode is a light sleep mode under third preset conditions including at least one of: a beam load being equal to or less than the second beam load threshold and greater than a third beam load threshold; a cell load being equal to or less than the second cell load threshold and greater than a third cell load threshold; a traffic data volume being equal to or less than the second traffic volume threshold and greater than a third traffic volume threshold; and a traffic delay sensitivity being delay insensitive; The method includes determining that the energy saving mode is a deep sleep mode under fourth preset conditions including at least one of: a beam load being less than or equal to the third beam load threshold; a cell load being less than or equal to the third load threshold; a traffic data volume being less than or equal to the third traffic volume threshold; and a traffic delay sensitivity being delay insensitive.

[0038] In the embodiment of the present application, the energy saving mode of the base station can be determined according to the beam load, cell load, traffic data volume and traffic delay sensitivity of the base station.

[0039] Specifically, when the base station satisfies at least one of the following conditions: the beam load is greater than a first beam load threshold, or the cell load is greater than a first cell load threshold, the traffic data volume of the base station is greater than a first traffic volume threshold, or the traffic delay sensitivity of the base station is delay sensitive, the base station energy saving mode is a non-energy saving mode.

[0040] The base station energy saving mode may be a microsleep mode when the base station satisfies at least one of the following conditions: the beam load is less than or equal to the first beam load threshold and greater than the 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 the 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 the second traffic volume threshold; and the traffic delay sensitivity of the base station is delay insensitive.

[0041] When the base station satisfies at least one of the following conditions: the beam load is less than or equal to the second beam load threshold and greater than the 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 the 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 the third traffic volume threshold; and the traffic delay sensitivity of the base station is delay insensitive, the base station energy saving mode is light sleep mode.

[0042] When the base station satisfies at least one of the following conditions: the beam load is equal to or less than the third beam load threshold; the cell load of the base station is equal to or less than the third load threshold; the traffic data volume of the base station is equal to or less than the third traffic volume threshold; and the traffic delay sensitivity of the base station is delay insensitive, the base station energy saving mode is deep sleep mode.

[0043] In one exemplary embodiment, a base station may consider turning off transmission of some signals when saving energy, and the off state may last for a few symbols, hundreds of milliseconds, a few seconds, or even a few minutes. Different off states have different degrees of energy saving, and the longer the duration, the better the energy saving effect. However, when saving energy, the base station must consider the impact on user equipment (UE). Turning off transmission and reception of different signals and different off times will have different impacts on the UE.

[0044] Three off modes are defined for the base station. 1. Microsleep: The duration may be a few symbols or a few milliseconds. The base station may affect the UE's schedule during the off period. The base station turns off transmission of signals such as PDCCH and PDSCH, and also turns off reception of signals such as PUSCH. In this state, the UE may perform one of the following activities: not monitoring the PDCCH, not transmitting the uplink shared channel, not reporting channel state information, not transmitting the PUCCH (except for reporting L1-RSRP signals), clearing the hybrid automatic repeat request (HARQ) buffer, deactivating all bandwidth parts (BWPs), or clearing all uplink resources. Here, the uplink resources may include configured uplink grant resources, SPS resources, SR resources, etc.

[0045] 2. Light sleep: The duration may be tens or hundreds of milliseconds. During this off period, the base station may affect the transmission and reception of beams from the UE. The base station turns off the transmission of signals such as PDCCH, PDSCH, CSI-RS, and SSB, and also turns off the reception of signals such as PUSCH and SRS. To reduce the impact on the UE, the base station may transmit sparse CSI-RS and SSB, such as with a period of 100 ms, or receive sparse SRS. In this state, the UE may perform one of the following activities: not monitoring the PDCCH; not monitoring the CSI-RS or receiving a sparse CSI-RS; not monitoring the SSB or receiving a sparse SSB; not transmitting the Physical Uplink Shared Channel; not transmitting an SRS or transmitting a sparse SRS; not reporting CSI; not transmitting a PUCCH or transmitting a sparse L1-RSRP; clearing the HARQ buffer; deactivating all BWPs; clearing all uplink resources (including configured uplink grant resources, SPS resources, SR resources, etc.).

[0046] 3. Deep Sleep: The duration may be hundreds of milliseconds, several seconds, several minutes, or even longer. During the off period, the base station may affect the UE's connectivity, causing the UE to experience radio link failures or inability to access the cell. The base station turns off all downlink signal transmission and all uplink signal reception. To reduce the impact on the UE, the base station may transmit sparse SSBs, such as those with a period of 200 ms, or receive sparse PRACHs. In this state, the UE may perform one of the following activities: not monitoring the PDCCH; not monitoring or receiving sparse CSI-RS; not monitoring or receiving sparse SSBs; not transmitting the UL-SCH; not transmitting the SRS; not reporting CSI; not transmitting the PUCCH; clearing the HARQ buffer; deactivating all BWPs; or clearing all uplink resources (including configured uplink grant resources, SPS resources, SR resources, etc.).

[0047] When entering the off mode, the base station may consider the cell load, for example:

[0048] 1. When the load of a beam or cell is heavy, the amount of traffic carried is large, and the traffic is sensitive to delay, the beam or cell is not turned off.

[0049] 2. When the load of a beam or cell is moderate, the amount of data of the traffic carried is small, and the traffic delay is insensitive, the beam or cell can be considered for microsleep.

[0050] 3. When the load on a beam or cell is light, the data volume of the traffic carried is small, the traffic delay is insensitive, and the number of UEs carried is small, the beam or cell can be considered for light sleep.

[0051] 4. When a beam or cell is lightly loaded and carries very few or no UEs, the beam or cell can be considered for deep sleep.

[0052] In the embodiments of the present application, the base station energy saving mode may be referred to as a sleep state, a deactivated state, a light load state, etc. The non-energy saving state of the base station may be a normal state, an activated state, a heavy load state, etc.

[0053] FIG. 4 is a flowchart of another base station energy saving method according to an embodiment of the present application, which is implemented based on the embodiment of the above application. Referring to FIG. 4, the method according to the embodiment of the present application specifically includes the following steps:

[0054] In step 310, an energy saving mode is determined. In step 320, signal processing corresponding to the energy saving mode is performed.

[0055] In step 330, the energy saving mode information is indicated. In an embodiment of the present application, the base station can indicate to the terminal the energy saving mode that has been entered, and the indication manner may include explicit indication or implicit indication. For example, the base station can indicate to the terminal device the energy saving mode that the base station has entered by signaling, and also, for example, if the base station does not receive feedback from the terminal device, it will implicitly indicate to the terminal device the energy saving mode that has been entered.

[0056] Furthermore, based on the embodiment of the above application, indicating the information of the energy saving mode can be Configuring periodic signal resources to be used for terminal device link recovery, beam failure monitoring, and candidate beam cycling; and configuring a periodic signal resource used for monitoring the wireless link of the terminal device.

[0057] In an embodiment of the present application, the base station can indicate the energy saving mode entered by configuring the type of signal resource of the terminal device, which may include configuring periodic signal resources used for the terminal device's link recovery, beam failure monitoring, and candidate beam period, and may also configure periodic signal resources used for the terminal device's radio link detection.

[0058] Furthermore, based on the embodiment of the above application, the signal resources include CSI-RS resources and synchronization signal block SSB resources.

[0059] Specifically, the signal resource indicating the energy saving mode set by the base station may be a CSI-RS resource or an SSB resource.

[0060] Furthermore, in accordance with an embodiment of the above application, signal resources are configured based on radio resource control (RRC) messages.

[0061] Specifically, the base station can set signal resources for indicating the energy saving mode by an RRC message.

[0062] Furthermore, based on the embodiment of the above application, the configuration parameters of the signal resource include at least two of a start time, a duration, and an end time.

[0063] In an embodiment of the present application, when a base station configures and instructs a terminal device to configure signal resources, the configuration parameters may be used, and the configuration parameters may include a start time and an end time, a start time and a duration, or an end time and a duration, etc.

[0064] FIG. 5 is a flowchart of another base station energy saving method according to an embodiment of the present application, which is implemented based on the embodiment of the above application. Referring to FIG. 5, the method according to the embodiment of the present application specifically includes the following steps:

[0065] In step 410, an energy saving mode is determined. In step 420, signal processing corresponding to the energy saving mode is performed.

[0066] In step 430, the signal resources detected by the terminal equipment under the preset conditions are indicated.

[0067] In an embodiment of the present application, a base station can instruct a terminal device to check signal resources under preset conditions, and the instruction may include an instruction for a signal resource. It can be understood that the preset conditions may be predefined by a protocol, may be instructed by a base station, or may be set by higher layer signaling. The types of signal resources checked by the instructed device under different preset conditions may be different.

[0068] Furthermore, based on the embodiments of the above application, signal resources are used for monitoring the radio link, and the signal resources include periodic CSI-RS resources or SSB resources, quasi-static CSI-RS resources or SSB resources, and aperiodic CSI-RS resources or SSB resources.

[0069] Specifically, the signal resources detected by the terminal under preset conditions instructed by the base station can be used for detecting the radio link, and the type of the signal resources may be periodic CSI-RS resources, periodic SSB resources, quasi-static CSI-RS resources, quasi-static SSB resources, aperiodic CSI-RS resources, aperiodic SSB resources, etc.

[0070] Further, based on the embodiment of the above application, the preset conditions include at least one of turning off the intensive CSI-RS resources or SSB resources, the base station entering an energy saving state, the base station instructing the terminal device to activate the CSI-RS resources or SSB resources, the terminal device detecting that the base station has entered an energy saving state, the terminal device detecting the disabling of the intensive CSI-RS resources or SSB resources, the terminal device detecting a sparse CSI-RS or SSB signal, the base station turning on the intensive CSI-RS resources or SSB resources, the base station entering a non-energy saving state, the base station instructing the terminal device to disable the CSI-RS resources or SSB resources, the terminal device detecting that the base station has entered a non-energy saving state, and the terminal device detecting the activation of the intensive CSI-RS resources or SSB resources.

[0071] In an embodiment of the present application, the preset conditions for the terminal device to detect signal resources may be one or more, and the preset conditions may include: the base station turning off the intensive CSI-RS resources; the base station turning off the intensive SSB resources; the base station entering an energy saving state; the base station instructing the terminal device to activate the CSI-RS resources; the base station instructing the terminal device to activate the SSB resources; the terminal device detecting that the base station has entered an energy saving mode; the terminal device detecting the disabling of the intensive CSI-RS resources; the terminal detecting the disabling of the intensive SSB resources; and the terminal device detecting the disabling of the sparse CSI-RS resources. The detection of CSI-RS may include one or more of the following: detecting CSI-RS; the terminal device detecting sparse SSB resources; the base station turning on intensive CSI-RS resources or SSB resources; the base station entering a non-energy saving state; the base station instructing the terminal device to disable CSI-RS resources or SSB resources; the terminal device detecting that the base station is entering a non-energy saving state; and the terminal device detecting the activation of intensive CSI-RS resources or SSB resources.When the terminal device is in a different preset condition, it can detect the same or different signal resources and achieve cooperation with the base station energy saving mode.

[0072] In one exemplary embodiment, if a base station decides to turn off transmission of some signals, the off state may last for tens or hundreds of milliseconds, and the base station may turn off the CSI-RS or SSB signals, i.e., enter an energy-saving mode. Because the CSI-RS or SSB signals are turned off, beam tracking, beam training, and beam management based on these signals are affected. If the off time exceeds a certain period of time, the UE may experience beam failure, i.e., the UE may be unable to find a suitable beam for service. If a beam failure occurs, the UE triggers a beam recovery process to search for a suitable beam. If no suitable beam is found, the UE selects an arbitrary beam and initiates a RACH process using the PRACH resource corresponding to that beam. If the RACH process is unsuccessful, the UE returns to the IDLE state until a radio link failure is triggered. It has been found that turning off the CSI-RS or SSB signals by the base station for a long period of time can cause cumbersome UE operation. To avoid the above problem, the following method can be adopted.

[0073] Method 1: When the base station attempts to turn off the CSI-RS or SSB signal or enter an energy saving state, the base station transmits a certain CSI-RS or SSB. The base station configures the UE with periodic CSI-RS or SSB resources used for link recovery, beam failure monitoring, and candidate beams, e.g., signal 1, where the period of these signals is dense. The UE monitors whether the beam can serve the UE based on these signals. When the base station attempts to turn off the transmission of these signals, to prevent beam failure from occurring in the UE, the base station transmits a certain CSI-RS or SSB, e.g., signal 2, where the period of these signals is sparser, as shown in FIG. 6. The frequency domain resources of signal 2 match those of signal 1. The period of signal 2 is a multiple of the period of signal 1. The start time of signal 2 is the transmission time of signal 1.

[0074] The time of a given CSI-RS or SSB (e.g., signal 2) is also specified by the base station and includes a start time, duration, or end time.

[0075] If the base station has not notified the UE of a change in the CSI-RS or SSB, the UE continues to monitor the CSI-RS or SSB according to the unchanged configuration.

[0076] When the base station notifies the UE of a change in CSI-RS or SSB, the UE does not monitor the unchanged CSI-RS or SSB, but monitors the changed CSI-RS or SSB based on the instruction of the base station.

[0077] Method 2: The base station indicates the CSI-RS or SSB resources that need to be detected under certain conditions. The base station configures the CSI-RS or SSB resources, and the signals are CSI-RS or SSBs used for link recovery, beam failure monitoring, and candidate beams. These signals may be periodic CSI-RS or SSBs, quasi-static CSI-RS or SSBs, or aperiodic CSI-RS or SSBs. The resources configured by the base station include frequency domain resources and time domain resources for these signals. If the base station configures periodic CSI-RS and SSBs, the configuration further includes a start time and a period.

[0078] The setting or transmission of these signals may be related to certain conditions. The setting of these signals may be related to an energy saving state. For example, when the base station enters an energy saving state, the period of the CSI-RS or SSB related to the condition is longer.

[0079] When a certain condition is met, the base station transmits these CSI-RS or SSB signals, and the UE also detects the beam based on these signals.

[0080] These conditions may include the base station turning off intensive CSI-RS or SSB resources, the base station entering an energy saving state, the base station indicating enabled or activated CSI-RS or SSB resources to the UE, the UE detecting that the base station has entered an energy saving state, the UE detecting the disabling of intensive CSI-RS or SSB signals, or the UE detecting sparse CSI-RS or SSB signals, etc.

[0081] If the UE knows that a certain condition has been reached, the UE will not monitor the CSI-RS or SSB under other conditions, but will monitor the CSI-RS or SSB corresponding to that condition.

[0082] The base station indicates CSI-RS or SSB resources that do not need to be detected under certain conditions. When a certain condition is reached, the base station does not transmit these CSI-RS or SSB signals, and the UE does not detect beams based on these signals. The conditions may be that the base station turns off aggregated CSI-RS or SSB resources, the base station enters a non-energy saving state, the base station indicates disabled or deactivated CSI-RS or SSB resources to the UE, the UE detects that the base station enters an activated state, the UE detects that aggregated CSI-RS or SSB signals are enabled, etc.

[0083] When a certain condition is reached, the base station stops transmitting these CSI-RS or SSB signals, and the UE also stops detecting beams based on these signals.

[0084] The CSI-RS or SSB resources configured by the base station may be configured by an RRC message, which may be a message such as RRCReconfiguration, RRCSetup, or RRCResume. The resources may also be broadcast in system information.

[0085] In one exemplary embodiment, when a base station decides to turn off transmission of some signals, the off state may last for hundreds of milliseconds or even several seconds, and the CSI-RS or SSB signals may be turned off, i.e., the base station enters an energy-saving mode. Because the CSI-RS or SSB signals are turned off, monitoring of the radio link based on these signals is affected. If the off time exceeds a certain period of time, a radio link failure may occur in the UE, i.e., the UE's radio link cannot be maintained. If a radio link failure occurs, the UE triggers RRC reestablishment or returns to the IDLE state. It can be seen that if the base station turns off the CSI-RS or SSB signals for a long period of time, the UE's connection will be lost.

[0086] To avoid the above problem, possible solutions are as follows: Method 1: When the base station intends to turn off the CSI-RS or SSB signal or enter an energy saving state, the base station transmits a certain CSI-RS or SSB. The base station configures the UE with CSI-RS or SSB resources used for monitoring the radio link, for example, signal 1, and the period of these signals is intensive. The UE monitors whether the serving cell can serve the UE based on these signals. When the base station intends to turn off transmission of these signals, to prevent the UE from experiencing a radio link failure, the base station transmits a certain CSI-RS or SSB, for example, signal 2, and the period of these signals is sparser, as shown in FIG. 7. The frequency domain resource of signal 2 matches signal 1. The period of signal 2 is a multiple of the period of signal 1. The start time of signal 2 is the transmission time of signal 1. The time of a certain CSI-RS or SSB (e.g., signal 2) is specified by the base station and includes a start time, duration, and end time.

[0087] Method 2: The base station indicates the CSI-RS or SSB resources that need to be detected under certain conditions. The base station configures the CSI-RS or SSB resources, and the signals are CSI-RS or SSBs used to monitor the radio link. These signals may be periodic CSI-RS or SSBs, quasi-static CSI-RS or SSBs, or aperiodic CSI-RS or SSBs. The resources configured by the base station include frequency-domain resources and time-domain resources of these signals. If the base station configures periodic CSI-RS and SSBs, the configuration further includes a start time and a period.

[0088] The setting or transmission of these signals may be related to a certain condition. The setting of these signals may be related to an energy saving state. For example, a condition may be that the base station enters an energy saving state, and the period of the CSI-RS or SSB associated with this condition is longer.

[0089] When a certain condition is met, the base station transmits these CSI-RS or SSB signals, and the UE also detects the radio link based on these signals.

[0090] The conditions may include the base station turning off intensive CSI-RS or SSB resources, the base station entering an energy saving state, the base station indicating enabled or activated CSI-RS or SSB resources to the UE, the UE detecting that the base station has entered an energy saving state, the UE detecting the disabling of intensive CSI-RS or SSB signals, or the UE detecting sparse CSI-RS or SSB signals, etc.

[0091] The base station indicates CSI-RS or SSB resources that do not need to be detected under certain conditions. When a certain condition is reached, the base station does not transmit these CSI-RS or SSB signals, and the UE does not detect beams based on these signals. The conditions may be that the base station turns on aggregated CSI-RS or SSB resources, the base station enters a non-energy saving state, the base station indicates disabled or deactivated CSI-RS or SSB resources to the UE, the UE detects that the base station enters an activated state, the UE detects that aggregated CSI-RS or SSB signals are enabled, etc.

[0092] When a certain condition is reached, the base station stops transmitting these CSI-RS or SSB signals, and the UE also stops detecting beams based on these signals.

[0093] The CSI-RS or SSB resources configured by the base station may be configured by an RRC message, which may be a message such as RRCReconfiguration, RRCSetup, or RRCResume. The resources may also be broadcast in system information.

[0094] FIG. 8 is a flowchart of a base station energy saving method according to an embodiment of the present application, which is implemented based on the embodiment of the above application. Referring to FIG. 8, the method according to the embodiment of the present application specifically includes the following steps:

The MAC CE or DCI may carry a cell identifier, an energy saving state indication bit, time information, etc. The cell identifier may be the identifier or index of the UE's serving cell. The energy saving state indication bit may be an indication bit for activating or not activating energy saving, for example, 1 bit, where 0 indicates that the base station has deactivated the energy saving state and 1 indicates that the base station has activated the energy saving state. Alternatively, it may be a state indicating the activation of energy saving, for example, 2 bits, where 00 indicates that the base station has deactivated the energy saving state, 01 indicates that the base station has activated microsleep, 10 indicates that the base station has activated light sleep, and 11 indicates that the base station has activated deep sleep, etc. The information carried in the MAC CE or DCI becomes valid a certain time after the UE receives the MAC CE or DCI.

[0108] FIG. 9 is a flowchart of a base station energy saving method according to an embodiment of the present application, which is implemented based on the embodiment of the above application. Referring to FIG. 9, the method according to the embodiment of the present application specifically includes the following steps:

[0109] In step 610, an energy saving mode is determined. In step 620, signal processing corresponding to the energy saving mode is performed.

[0110] In step 630, an enable instruction enables the terminal device to detect the energy-saving mode.

[0111] In an embodiment of the present application, the base station can send an enable instruction to the terminal device, and the terminal device can detect the base station energy saving mode after receiving the enable instruction.

[0112] Furthermore, in one embodiment, the RRC message enables the terminal device to determine the base station energy saving mode based on the detection of the CSI-RS resource or the SSB resource.

[0113] In an embodiment of the present application, the base station may send an RRC message to the terminal device, so that the terminal device can detect the CSI-RS resource or SSB resource and determine the base station energy saving mode.

[0114] Furthermore, in another embodiment, the system information enables the terminal device to determine the base station energy saving mode based on detecting CSI-RS resources or SSB resources.

[0115] Specifically, the base station can also transmit system information to the terminal device, and after receiving the system information, the terminal device can detect CSI-RS resources or SSB resources, and can determine the base station energy saving mode according to the detection result of the CSI-RS resources or SSB resources.

[0116] Further, based on the embodiment of the above application, the enable instruction carries a threshold value for the energy-saving mode, and the threshold value includes at least one of time period information, a maximum signal detection number threshold value, and a minimum signal detection number threshold value.

[0117] In an embodiment of the present application, the enable instruction may carry a threshold for detecting an energy saving mode, which may specifically be information such as time period information, a maximum signal detection count threshold N1, a minimum signal detection count threshold N2, etc. The terminal device may detect CSI-RS resources or SSC resources based on the threshold, and if the resource detection result satisfies the threshold, it may determine the energy saving mode corresponding to the base station. Here, the enable instruction may specifically include an RRC message or system information.

[0118] In one exemplary embodiment, the UE can detect signal resources based on the RRC message or system information sent by the base station, so that the UE can determine the energy saving mode that the base station has entered. Specifically, the manner in which the UE detects the base station energy saving mode may include the following methods:

[0119] Method 1: The UE cannot detect the CSI-RS or SSB signal. The base station enables the UE to determine the base station energy saving state through an RRC message or system information. If enabled, the UE can determine the base station energy saving state by detecting the CSI-RS or SSB signal. The base station can also broadcast and set energy saving state thresholds, such as time information and an upper limit N value, through an RRC configuration or system information.

[0120] The base station configures periodic CSI-RS or SSB resources for link recovery, beam failure monitoring, and candidate beams, and the periodicity of these signals is intensive. The UE periodically detects the quality of these signals. If the UE cannot detect N signals within a certain time period, or if the UE cannot detect N signals consecutively within a certain time period, the UE can assume that the base station has stopped transmitting these signals and entered an energy saving state. In different energy saving states of the base station, the UE detects the CSI-RS or SSB associated with the energy saving state.

[0121] For example, if the UE fails to detect N signals S1 within a certain time period 1, the UE considers the base station to have entered a light sleep state. The UE detects a signal S2 associated with it, such as a sparse CSI-RS or SSB.

[0122] If the UE fails to detect N2 signals S2 within a certain time 2, the UE assumes that the base station has entered a deep sleep state. The UE detects a signal S3 associated with it, such as a sparser CSI-RS or SSB.

[0123] The base station configures CSI-RS or SSB resources used to monitor the radio link, and the period of these signals is intensive. The UE periodically detects the quality of these signals. If the UE cannot detect N signals within a certain time period, or if the UE cannot detect N signals consecutively within a certain time period, the UE can assume that the base station has stopped transmitting these signals and entered an energy-saving state. In the energy-saving state, the UE detects the associated CSI-RS or SSB.

[0124] For example, if the UE fails to detect N signals S1 within a certain time period 1, the UE considers the base station to have entered a deep sleep state. The UE detects a signal S2 associated with it, such as a sparse CSI-RS or SSB.

[0125] Method 2: The UE detects a CSI-RS or SSB signal. The base station enables the UE to determine the base station energy saving state through an RRC message or system information. If enabled, the UE can determine the base station's non-energy saving state by detecting the CSI-RS or SSB signal. The base station can also broadcast and set non-energy saving state thresholds, such as time information and a lower limit N value, through RRC configuration or system information.

[0126] The base station configures periodic CSI-RS or SSB resources used for link recovery, beam failure monitoring, and candidate beams in an energy saving state, and the periodicity of these signals is sparse.The base station configures periodic CSI-RS or SSB resources used for link recovery, beam failure monitoring, and candidate beams in a non-energy saving state, and the periodicity of these signals is intensive.

[0127] If the UE detects N signals within a certain time period, or if the UE detects N signals consecutively within a certain time period, the UE can assume that the base station has transmitted these signals and that the base station has entered an energy-saving or non-energy-saving state. In an energy-saving or non-energy-saving state, the UE detects its associated CSI-RS or SSB.

[0128] For example, if the UE detects N signals S1 within a certain time period, the UE considers the base station to have entered a light sleep state. The UE detects signals S1 associated with it, such as aggregate CSI-RS or SSB.

[0129] If the UE detects N2 signals S2 within a certain time 2, the UE considers that the base station has entered a non-energy saving state. The UE detects signals S2 related to it, such as aggregate CSI-RS or SSB.

[0130] The base station configures CSI-RS or SSB resources used for monitoring the radio link in an energy saving state, and the period of these signals is sparse. The base station configures CSI-RS or SSB resources used for monitoring the radio link in a non-energy saving state, and the period of these signals is intensive.

[0131] If the UE detects N signals within a certain time period, or if the UE detects N signals consecutively within a certain time period, the UE can assume that the base station has transmitted these signals and that the base station has entered an energy-saving or non-energy-saving state. In an energy-saving or non-energy-saving state, the UE detects its associated CSI-RS or SSB.

[0132] For example, if the UE detects N signals S1 within a certain time period, the UE considers the base station to have entered a non-energy saving state. The UE detects signals S1 associated with it, such as aggregate CSI-RS or SSB.

[0133] FIG. 10 is a flowchart of another base station energy saving method according to an embodiment of the present application, which is implemented based on the embodiment of the above application. Referring to FIG. 10, the method according to the embodiment of the present application specifically includes the following steps:

[0134] In step 710, an energy saving mode is determined. In step 720, if the terminal device has a dual link established, energy saving of a primary secondary cell (PScell) is performed.

[0135] In an embodiment of the present application, when a dual link is configured in a terminal device, the base station performs corresponding processing on the primary secondary cell when implementing an energy saving mode, so as to enable the primary secondary cell PScell ​​to achieve energy saving.

[0136] Furthermore, based on the embodiment of the above application, energy saving of the primary secondary cell PScell ​​can be achieved by: The method includes at least one of instructing the primary secondary cell to deactivate by MAC CE or DCI signaling, and instructing the primary secondary cell to activate by MAC CE or DCI signaling.

[0137] In an embodiment of the present application, the method for controlling energy saving of a primary secondary cell may include instructing the primary secondary cell to be activated or deactivated by signaling, where the signaling may specifically be MAC CE or DCI signaling.

[0138] Furthermore, based on the embodiment of the above application, the MAC CE or DCI command carries at least one of the following information: a cell identifier, a deactivation indication bit, time information, and an activation indication bit.

[0139] In one exemplary embodiment, when a dual link is configured for a UE, when a base station intends to take energy saving measures for a PSCell, the PSCell can turn off some services and control the energy saving of the PSCell, specifically including the following method:

[0140] Method 1: Instructing a PSCell to be deactivated by MAC CE or DCI. The MAC CE or DCI may carry a cell identifier, a deactivation indication bit, time information, etc. The cell identifier may be a PSCell identifier or index of the UE. The deactivation indication bit may be an indication bit indicating whether to deactivate the PSCell. For example, the indication bit is 1 bit, and a set of 1 bit represents the deactivation state of the base station. The time information may include a start time, a duration, or an end time. After a certain time has passed since the UE received the MAC CE or DCI, the information carried in the MAC CE or DCI becomes valid and the PScell ​​is deactivated. The activation time, duration, or end time may be carried in the time information.

[0141] Method 2: Instructing a PSCell to be activated by a MAC CE or DCI. The MAC CE or DCI is transmitted by an MCG. The MAC CE or DCI may carry a cell identifier, an activation indication bit, time information, etc. The cell identifier may be a PSCell identifier or index of the UE. The activation indication bit may be an indication bit for whether to activate a PSCell. For example, the indication bit is 1 bit, and a set of the 1 bit represents the activation state of the base station. The time information may include a start time. After a certain time has passed since the UE received the MAC CE or DCI, the information carried in the MAC CE or DCI becomes valid and activates the PSCell. The activation time may be carried in the time information.

[0142] Further, based on the embodiment of the above application, it further includes transmitting a simplified system information block SIB containing cell access information.

[0143] In an embodiment of the present application, a base station consumes a lot of power when transmitting a system information block (SIB). However, if the SIB is not transmitted, a UE that moves into the coverage area will not be able to camp. In order to reduce power consumption, the base station can transmit a simplified SIB, which only provides cell access information.

[0144] Further, based on the embodiment of the above application, the cell access information includes at least one of a PLMN identifier, a TAC identifier, a reservation identifier, a PRACH configuration, and SIB1 schedule information.

[0145] Specifically, the PLMN identifier may be identification information of a Public Land Mobile Network (PLMN), the TAC identifier may be a Type Allocation Code (TAC), the PRACH configuration may be configuration information of a Physical Random Access Channel (PRACH), the SIB1 schedule information may be a schedule block carrying cell selection information, and the reservation identifier may be a reserved identification bit, which can be used to identify other customization information.

[0146] In one exemplary embodiment, in order to balance base station energy saving and camping of UEs that have moved into coverage, the base station may take the following method.

[0147] The base station transmits a simplified SIB, e.g., simplified SIB1, providing only the cell's access information, such as a PLMN identifier, a TAC identifier, a reservation identifier, and the like, and PRACH configuration (including frequency domain and delay resources). Some PRACH resources may be associated with the normal SIB1, and some PRACH resources may be associated with a base station wake-up function. The simplified SIB1 may also provide the normal SIB1's schedule information, such as the transmission time. However, the cell or initial BWP does not provide PDCCH configuration or channel configuration, such as PUSCH or PDSCH. The UE can obtain the simplified SIB1 by selecting the cell and determine whether the cell satisfies the camping conditions based on the access information. If so, the UE camps on the cell. When the UE wants to transmit traffic or select to camp on the cell, the UE can transmit a preamble based on the configuration. However, the UE does not listen to the PDCCH corresponding to the RAR. After receiving the SIB1, the base station determines that there is a UE camped on the cell, and sends a normal SIB1. The UE receives the SIB1 again and decides whether to camp on the cell or transmit traffic based on the setting.

[0148] FIG. 11 is a flowchart of a base station energy saving method according to an embodiment of the present application. The embodiment of the present application is applied when the base station enters an energy saving mode, and the method can be performed in a base station energy saving device, which is generally integrated in a terminal device. Referring to FIG. 11, the method according to the embodiment of the present application specifically includes the following steps:

[0149] In step 810, the indication information of the base station is obtained. Here, the indication information is information for indicating that the base station has entered an energy saving state, and the indication information may be implicit indication information or explicit indication information. For example, the indication information may include the type of energy saving mode the base station has entered, or the indication information is a signal resource, and the terminal can determine the energy saving mode the base station has entered by detecting the signal resource.

[0150] Specifically, the terminal device can receive the instruction information transmitted by the base station.

[0151] In step 820, the resource is detected based on the energy saving mode corresponding to the indication information.

[0152] In the embodiment of the present application, the terminal device can perform resource detection according to the energy saving mode corresponding to the indication information.

[0153] The embodiments of the present application obtain instruction information from the base station and perform corresponding resource detection according to the energy saving mode corresponding to the instruction information, thereby realizing energy saving for the base station in different cases and reducing the power consumption of the base station while ensuring communication quality.

[0154] Furthermore, based on the embodiment of the above application, obtaining the indication information of the base station can be This includes at least one of obtaining periodic signal resources for link recovery, beam failure monitoring, and candidate beam periods set by the base station, and obtaining periodic signal resources for radio link monitoring set by the base station.

[0155] Furthermore, based on the embodiment of the above application, obtaining the indication information of the base station includes obtaining the signal resource detected under the indicated preset condition.

[0159] Here, the enable indication may be information that triggers the terminal to detect the energy saving mode, and the enable indication may specifically be an RRC message or system information received by the terminal.

[0160] In an embodiment of the present application, the terminal may receive enable instruction information for detecting an energy saving mode, and after receiving the instruction information, the terminal may detect the base station energy saving mode, for example, the terminal may receive an RRC message or system information for enabling the detection of the energy saving mode.

[0161] In step 920, a CSI-RS resource or an SSB resource corresponding to an energy saving mode is detected.

[0162] Specifically, the terminal may perform resource detection according to the detected energy saving mode triggered based on the enable indication, which may include detecting CSI-RS resources or detecting SSB resources.

[0163] Furthermore, based on the examples of the above application, The method further includes receiving time period information and at least one signal detection minimum threshold in the enable instruction, each of the detection minimum thresholds corresponding to a different energy saving mode; obtaining the number of the CSI-RS resources or the SSB resources detected within a time range of the time period information; and, if the number is smaller than the signal detection minimum threshold, determining that the base station energy saving mode is the energy saving mode corresponding to the detection minimum threshold.

[0164] In an embodiment of the present application, the enable instruction may carry time period information and a minimum signal detection number threshold for detecting an energy saving mode, and each minimum signal detection number threshold may correspond to an energy saving mode, and the correspondence may be carried by the enable instruction or may be preset. After receiving the enable instruction, the terminal device may detect the number of CSI-RS resources or SSB resources according to the time period information therein. If the number is smaller than the minimum signal detection number threshold, the base station energy saving mode detected by the terminal is the energy saving mode corresponding to the minimum signal detection number threshold.

[0165] Furthermore, based on the examples of the above application, The method further includes receiving time period information and at least one signal detection number maximum threshold in the enable instruction, each of the detection number maximum thresholds corresponding to a different energy saving mode; obtaining a number of CSI-RS resources or SSB resources detected within a time range of the time period information; and, if the number is greater than the signal detection number maximum threshold, determining that the base station energy saving mode is the energy saving mode corresponding to the detection number maximum threshold.

[0166] Specifically, the enable instruction may carry time period information and a signal detection number maximum threshold for detecting the energy saving mode, and each signal detection number maximum threshold may correspond to one energy saving mode, and the correspondence may be carried by the enable instruction or may be preset. After receiving the enable instruction, the terminal device may detect the number of CSI-RS resources or SSB resources according to the time period information therein. If the number is greater than the signal detection number maximum threshold, the base station energy saving mode detected by the terminal is the energy saving mode corresponding to the signal detection number maximum threshold.
