[0183] In the disclosed embodiment, the WUS signal may be used for the connected state, inactive state, idle state, and other states of the radio resource control RRC. The LP WUS signal can instruct the terminal main radio to switch between any two sleep states, and can also instruct the terminal to wake up or not wake up. If the terminal receives a WUS signal indicating wakeup, it will turn on the main radio to receive and process downlink and / or uplink signals. If no WUS signal is received, or the WUS indicates not to wake up, the UE will maintain the current sleep state of the main radio. There are four sleep states of MR, namely ultra-deep sleep, deep sleep, light sleep, and micro sleep.

[0184] In the disclosed embodiments, LP WUR operates in two modes: always on and duty cycle. In always on mode, the terminal's LP WUR is always on, and the base station can send an LP WUS to wake the terminal at any time. In duty cycle mode, the terminal uses a mechanism to only turn on the LP WUR during the LP WUS listening window, and the base station can only send an LP WUS to wake the terminal during this time period.

[0185] In the embodiment of the present disclosure, considering the time-frequency deviation during the operation of the LP WUR, the LP SS is introduced to assist the time-frequency synchronization during the reception process of the LP WUS.

[0186] In the embodiments of the present disclosure, there are two potential operating modes of the LP SS. One is per-cell configuration of the LP SS, i.e., a cell is configured with only one public LP SS, and all UEs synchronize their LP WUS reception by receiving the LP SS. The other is per-UE or UE group configuration of the LP SS.

[0187] In the embodiment of the present disclosure, there are two potential relationships between the waveform of the LP SS and the waveform of the LP WUS. One is that the waveform is the same as the LP WUS waveform, for example, both are OOK waveforms; the other is that the waveform is different from the LP WUS waveform, for example, the LP SS is OFDM, while the LP WUS is OOK.

[0188] In the embodiment of the present disclosure, there are two potential ways of sending LP SS, one is periodic sending, and the other is aperiodic sending.

[0189] In an embodiment of the present disclosure, in a network, a base station can wake up terminals supporting LP WUS in a cell or change the sleep state of these terminals by sending LP WUS. For terminals supporting LP WUS, at least one LP WUS signal is received through LP WUR, and the MR wake-up or sleep state change is completed according to the information carried by the received LP WUS signal. Among them, the change of the MR's sleep state refers to the mutual switching between super deep sleep, deep sleep, light sleep, shallow sleep and other states, and the MR wake-up refers to the MR transitioning from any sleep state to the wake-up state. Before receiving the LP WUS, the UE's LP WUR attempts to receive the LP SS to obtain auxiliary information of the LP WUS, such as time-frequency synchronization information, cell ID information, etc. The base station sends the LP SS according to the protocol-defined configuration or the configuration indicated by the base station to at least one UE, and the UE monitors the LP SS according to the protocol predefined configuration or the base station configuration.

[0215] In some embodiments, the offset of the signal cycle is the time interval between the time when the terminal receives the first signaling and the start time of the signal cycle. Alternatively, the offset of the signal cycle refers to the time offset between the time when the terminal receives the first signaling and the start position of the LP SS signal cycle. The unit of measurement of this time offset is symbol, time slot, sub-radio frame, radio frame, half-radio frame, etc. In some embodiments, the terminal can determine the start time of the signal cycle based on the time when the first signaling is received and the offset of the signal cycle. For example, assuming that the time when the terminal receives the first signaling is a and the offset of the signal cycle is b, the start time of the signal cycle can be a+b.

[0263] Step S203 : The network device 102 sends second information to the terminal 101 .

[0264] In some embodiments, the terminal 101 receives the second information. Optionally, the second information is carried in MIB, SIB or RRC signaling.

[0265] In some embodiments, the second information is used to indicate a target signal period currently used by the network device to transmit the LP SS.

[0266] In some embodiments, the second information is used to indicate a target signal period among a plurality of candidate signal periods.

[0267] In some embodiments, the name of the second information is not limited, and it can be, for example, valid resource indication information, an instruction indicating a valid signal period, etc.

[0268] Step S204: Terminal 101 determines a target signal period according to the second information.

[0269] Optionally, the terminal determining the target signal period according to the second information includes: the terminal determining the target signal period according to the first information / resource configuration information of the LP SS and the second information.

[0270] Optionally, the terminal determining the target signal period based on the second information includes: the terminal determining the target signal period based on the configuration data of the first configuration item and the second information. In some embodiments, if the terminal determines that the first configuration item corresponds to multiple candidate signal periods, and the multiple candidate signal periods include the target signal period currently used by the network device to send LP SS, the network device may indicate the target signal period currently used to send LP SS to the terminal via the second information. For example, assuming that the first configuration item corresponds to four candidate signal periods, the network device sends the second information to the terminal. The second information carries two bits, and the two bits are used to indicate that one of the four candidate signal periods is the target signal period. For example, the two bits are 01, indicating that the second candidate signal period is the target signal period.

[0271] If the terminal determines that the first configuration item corresponds to multiple candidate signal periods, in addition to determining the target signal period based on the second information in step S204, the terminal may also determine the target signal period in the following manner: The terminal determines a first candidate signal period. Optionally, the first candidate signal period is any one of the multiple candidate signal periods. Optionally, the terminal may determine the first candidate signal period from the multiple candidate signal periods through blind selection or random selection. Preferably, the first candidate signal period is the minimum value among the multiple candidate signal periods. The terminal monitors the LPSS according to the first candidate signal period and determines the target signal period based on the time information of obtaining the LPSS. For example, the terminal monitors the LPSS according to the first candidate signal period and determines the target signal period based on the time information of two consecutive LPSS acquisitions. For example, assuming that the candidate signal periods corresponding to the first configuration item are 5, 10, and 20, the first candidate signal period may be 5. The terminal monitors the LPSS according to the period 5. If the target signal period is actually 20, this means that the terminal may receive the LPSS at most four times by detecting according to the period 5. After receiving the LPSS twice, the terminal can determine the target signal period.

[0272] Step S205 : The network device 102 sends third information to the terminal 101 .

[0273] In some embodiments, the terminal 101 receives the third information. Optionally, the second information is carried in MIB, SIB or RRC signaling.

[0276] In some embodiments, the name of the third information is not limited, and it can be, for example, symbol configuration information, time domain mode information, etc.

[0277] Step S206: Terminal 101 determines a target time-domain symbol pattern according to the third information.

[0278] Optionally, the terminal determining the target time-domain symbol pattern according to the third information includes: the terminal determining the target time-domain symbol pattern according to the first information / resource configuration information of the LP SS and the third information.

[0279] Optionally, the terminal determines the target time domain symbol mode according to the third information, including: the terminal determines the target time domain symbol mode according to the configuration data of the fourth configuration item and the third information. In some embodiments, if the terminal determines that the fourth configuration item corresponds to multiple candidate time domain symbol modes, and the multiple candidate time domain symbol modes include the target time domain symbol mode currently used by the network device to send LP SS. Then the network device may indicate the target time domain symbol mode currently used to send LP SS to the terminal through the third information. For example, it is assumed that the fourth configuration item corresponds to 4 candidate time domain symbol modes. The network device sends the third information to the terminal, and the third information carries two bits, and the two bits are used to indicate that one of the 4 candidate time domain symbol modes is the target time domain symbol mode. For example, the two bits are 00, indicating that the first candidate time domain symbol mode is the target time domain symbol mode.

[0280] In some embodiments, the target time-domain symbol pattern for the network device to transmit LPS can be determined based on protocol pre-defined specifications. For example, the protocol specifies that the SSB set pattern and the LPS pattern be bound to each other. Based on the currently used SSB set pattern, the terminal can determine the target time-domain symbol pattern for the network device to transmit LPS.

[0281] In some embodiments, any configuration item described in the optional implementation of step S202 above may correspond to multiple candidate values. The network device may indicate to the terminal the currently valid value among the multiple candidate values ​​for each configuration item, and the terminal executes step S207 based on the currently valid value of each configuration item. The implementation method for the network device indicating to the terminal the currently valid value among the multiple candidate values ​​for each configuration item can be found in the optional implementation of steps S203 to S206 above and will not be further described here.

[0282] In step S207, the terminal 101 monitors the LP SS.

[0283] In some embodiments, the terminal monitors all LP SSs sent by the network device within the target signal period according to the valid value of at least one configuration item recorded in the optional implementation of step S202 above.

[0284] In step S208, the terminal 101 determines auxiliary information of the LP WUS according to the monitored LP SS, and receives the LP WUS according to the auxiliary information.

[0285] In some embodiments, the auxiliary information is used to at least assist in time-frequency synchronization during the LP WUS reception process. Optionally, the auxiliary information includes, but is not limited to, time-frequency synchronization information of the LP WUS, cell ID information, etc. The time-frequency synchronization information of the LP WUS may include a time-frequency offset, a reference signal, etc. of the LP WUS.

[0407] The optional implementation of step S5202 can refer to the optional implementation of step S202 in Figure 2, step S3102 in Figure 3A, and other related parts in the embodiments involved in Figures 2 and 3A, which will not be repeated here.

[0408] In some embodiments, the above method may include the method described in the above embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0409] In some embodiments, the time domain resource configuration information is configured by referring to the SSB, configuring the LP synchronization period, detecting the LP SS at a fixed frequency, designing an LP SS pattern in the time domain, and performing detection according to the pattern.

[0410] In some embodiments, as shown in FIG6A , it is assumed that the LP synchronization period is 160 ms, the subcarrier spacing SCS is 15 kHz, one time slot is 1 ms, the reference frequency a is the center frequency of the carrier / initial BWP, the LP SS period corresponds to the first pattern, the time domain length of the pattern is one slot, and the 3rd, 4th, 10th, and 11th symbols in the time slot carry the LP SS.

[0411] In some embodiments, as shown in FIG6B , it is assumed that the LP synchronization period is 160 ms, the SCS is 15 kHz, one time slot is 1 ms, the reference frequency a is the center frequency of the carrier / initial BWP, the LP SS period corresponds to the first pattern, the time domain length of the pattern is half a radio frame, the first and third time slots in the pattern carry LP SSs, and each LP SS occupies the time domain length of one time slot.

[0412] In some embodiments, the time domain resource configuration information is configured by referring to the multi-PUSCH CG configuration, configuring an LP monitoring period, configuring multiple occasions within the LP monitoring period, for example, N consecutive slots, each occasion reuses the SLIV configuration of the first occasion, and performs LP SS monitoring according to the configuration.

[0413] In some embodiments, as shown in FIG6C , it is assumed that the LP synchronization period is 160 ms, the SCS is assumed to be 15 kHz, one time slot is 1 ms, the reference frequency a is the center frequency of the carrier / initial BWP, and the LP SS period is configured with three occasions. The first time slot corresponds to the first SLIV indication time slot, and the LP SS is carried on the 3rd to 12th symbols.

[0414] In some embodiments, the time domain resource configuration information is configured by combining the two aforementioned methods, i.e., referring to the SSB and multi-PUSCH CG configurations. Similarly, a single LP listening period is configured, and multiple patterns are configured within the LP listening period, for example, N consecutive patterns. The first pattern configuration is fixed, for example, occupying the first two symbols in the first slot.

[0415] In some embodiments, as shown in FIG6D , the LP synchronization period is 160 ms, the SCS is assumed to be 15 kHz, one time slot is 1 ms, the reference frequency a is the center frequency of the carrier / initial BWP, and the LP SS period is configured with three occasions. The first time slot corresponds to the first pattern, and the 3rd, 4th, 10th, and 11th symbols in the time slot of the pattern carry the LP SS.

[0416] In some embodiments, the time domain configuration of the LP SS can be selected to correspond to the SSB and LP WUS configurations. Similar to SSB, different LP SSs correspond to different beams, and one LP SS corresponds to the SSB of one beam.

[0417] In some embodiments, frequency domain resource configuration information tends to be configured using a simple mechanism. For example, a fixed bandwidth, either consistent with the BWP bandwidth or the LP WUS signal bandwidth, can be configured implicitly by setting a reference frequency plus an offset.

[0418] In some embodiments, in a network, a base station can wake up terminals supporting LP WUS in a cell or change the sleep state of these terminals by sending LP WUS. For terminals supporting LP WUS, at least one LP WUS signal is received through LP WUR, and the awakening or sleep state change of MR is completed according to the information carried by the received LP WUS signal. Among them, the change of the sleep state of MR refers to the mutual switching among super deep sleep, deep sleep, light sleep, shallow sleep and the like, and the awakening of MR refers to the transition of MR from any sleep state to the awakened state. Before receiving LP WUS, the UE's LP WUR attempts to receive LP SS to obtain auxiliary information of LP WUS, such as time-frequency synchronization information, cell ID information, etc. The base station sends the LP SS according to the protocol-defined configuration or the configuration indicated by the base station to at least one UE, and the UE monitors the LP SS according to the protocol predefined configuration or the base station configuration.

[0419] In some embodiments, based on the above, the LP SS signal period (LP synchronization period) is the time required for at least one group of LP SS signals to be transmitted once, and the determination method thereof includes at least one of the following:

[0420] In some embodiments, the LP SS signal period is determined in a protocol-predefined manner, where the LP SS signal period is specifically an absolute time or at least one time unit. An absolute time may include, for example, 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, 160 ms, 64 ms, 128 ms, 456 ms, 320 ms, 640 ms, 1280 ms, 50 ms, 100 ms, 200 ms, 400 ms, or 800 ms. At least one relative time unit may include, for example, 5, 10, 20, 40, 80, 160, 64, 128, 456, 320, 640, 1280, 50, 100, 200, 400, or 800 time units, where the time units include a slot, a sub-radio frame, a radio frame, or a half-radio frame.

[0421] In some embodiments, the network configures an LP SS signal period through first RRC signaling, where the LP SS signal period is specifically an absolute time or at least one time unit. Absolute time includes, for example, 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, 160 ms, 64 ms, 128 ms, 456 ms, 320 ms, 640 ms, 1280 ms, 50 ms, 100 ms, 200 ms, 400 ms, or 800 ms. At least one relative time unit includes, for example, 5, 10, 20, 40, 80, 160, 64, 128, 456, 320, 640, 1280, 50, 100, 200, 400, or 800 time units, where the time units include a slot, a sub-radio frame, a radio frame, or a half-radio frame.

[0422] In some embodiments, the network configures the LP SS signal period through system information (MIB / SIB). The LP SS signal period is specifically an absolute time or at least one time unit. Absolute time includes, for example, 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, 160 ms, 64 ms, 128 ms, 456 ms, 320 ms, 640 ms, 1280 ms, 50 ms, 100 ms, 200 ms, 400 ms, or 800 ms. At least one relative time unit includes, for example, 5, 10, 20, 40, 80, 160, 64, 128, 456, 320, 640, 1280, 50, 100, 200, 400, or 800 time units. The time units include a slot, a sub-radio frame, a radio frame, or a half-radio frame.

[0423] In some embodiments, in addition to the above-mentioned embodiment, the method for determining the LP SS signal period further includes determining at least one LP SS signal period offset. The LP SS signal period offset refers to the time offset (measured in time slots or symbols) between the UE receiving the LP SS signal period indication signaling configured by the base station and the start position of the LP SS signal period. The measurement unit of the time offset includes at least one of a time domain symbol, a time slot, a sub-radio frame, and a half-radio frame. Furthermore, the LP SS signal period offset may be predefined by the protocol, configured by RRC signaling, or configured by system messages.

[0424] In some embodiments, at least one LP SS signal cycle second offset is determined. The LP SS signal cycle second offset refers to the time offset between a specific radio frame, specific signaling, or DCI dynamic signaling and the start position of the LP SS signal cycle. The time offset is measured in units of at least one of a time domain symbol, a time slot, a sub-radio frame, and a half-radio frame. Furthermore, the LP SS signal cycle offset may be predefined by a protocol, configured by RRC signaling, or configured by a system message.

[0425] In some embodiments, when the LP SS signal period is not configured / indicated to the terminal, the terminal assumes that the LP SS signal period is a first value. The first value is predefined by the protocol and is equivalent to the second candidate signal period in the aforementioned embodiment.

[0426] In some embodiments, when the LP SS signal period is determined, it is further necessary to determine the time slot position of the LP SS transmission within the LP SS signal period.

[0427] In some embodiments, the LP SS signal is sent K time slots before / after the LP SS signal cycle, where K is predefined by the protocol.

[0433] In some embodiments, in a network, a base station can wake up terminals supporting LP WUS in a cell or change the sleep state of these terminals by sending LP WUS. For terminals supporting LP WUS, at least one LP WUS signal is received through LP WUR, and the awakening or sleep state change of MR is completed according to the information carried by the received LP WUS signal. Among them, the change of the sleep state of MR refers to the mutual switching among super deep sleep, deep sleep, light sleep, shallow sleep and the like, and the awakening of MR refers to the transition of MR from any sleep state to the awakened state. Before receiving LP WUS, the UE's LP WUR attempts to receive LP SS to obtain auxiliary information of LP WUS, such as time-frequency synchronization information, cell ID information, etc. The base station sends the LP SS according to the protocol-defined configuration or the configuration indicated by the base station to at least one UE, and the UE monitors the LP SS according to the protocol predefined configuration or the base station configuration.

[0434] In some embodiments, based on the above, there are two ways to configure the LP SS time domain resources: one is to configure the LP SS time domain pattern, and the other is to allocate time domain symbol resources. Specifically, the LP SS time domain resource configuration method includes at least one of the following:

[0435] In some embodiments, the time domain position of at least one LP SS within a time period is indicated. The time period is preferably one or more slots. The determination method includes at least one of the following:

[0436] In some embodiments, the protocol predefines an LPSS time-domain pattern, where the LPSS time-domain pattern refers to the time-domain position of at least one LPSS within a time period. The time-domain length of the time period is at least 14 symbols (12 symbols for ECP), one time slot, or multiple time slots. The time period of an LPSS time-domain pattern includes at least one LPSS symbol, and the LPSS symbol occupies at least one time-domain symbol.

[0437] In some embodiments, the protocol predefines the time domain resources of the first LPSS within an LPSS signal cycle. For example, in a second time unit, the first LPSS is configured to have at least one symbol in the second time unit occupied by the LPSS, such as the first M symbols, where M is a positive integer. The remaining LPSSs reuse the configuration of the first LPSS.

[0438] In some embodiments, the first RRC signaling configures the time domain resources of the first LPSS within the LPSS signal cycle. For example, in the second time unit, the first LPSS configures at least one symbol in the second time unit as the time domain resource occupied by the LPSS, such as the first M symbols, where M is a positive integer, or any one or more consecutive symbols among 14 symbols configured through SLIV. The remaining LPSSs reuse the configuration of the first LPSS.

[0439] In some embodiments, a system message (MIB / SIB) configures the time domain resources of the first LPSS within an LPSS signal cycle. For example, in a second time unit, at least one symbol in the second time unit configured for the first LPSS is the time domain resource occupied by the LPSS, such as the first M symbols, where M is a positive integer, or any one or more consecutive symbols among 14 symbols configured via SLIV. The remaining LPSSs reuse the configuration of the first LPSS.

[0440] In some embodiments, the second RRC signaling indicates the LP SS time domain pattern within the LP SS signal period. For example, the protocol predefines four candidate LP SS time domain patterns, and the second RRC signaling carries two bits to indicate one of the four candidate LP SS time domain patterns.

[0441] In some embodiments, system information (MIB / SIB) indicates the LP SS time domain pattern within the LP SS signal period. For example, the protocol predefines four candidate LP SS time domain patterns, and the PBCH carries two bits to indicate one of the four candidate LP SS time domain patterns.

Among them, the change of the sleep state of MR refers to the mutual switching among super deep sleep, deep sleep, light sleep, shallow sleep and the like, and the awakening of MR refers to the transition of MR from any sleep state to the awakened state. Before receiving LP WUS, the UE's LP WUR attempts to receive LP SS to obtain auxiliary information of LP WUS, such as time-frequency synchronization information, cell ID information, etc. The base station sends the LP SS according to the protocol-defined configuration or the configuration indicated by the base station to at least one UE, and the UE monitors the LP SS according to the protocol predefined configuration or the base station configuration.
