Wireless communication method and apparatus therefor

Abstract

A wireless communication method for a first communication node is disclosed. The method includes a process of receiving a first signal from a second communication node and determining a second signal based on the first signal.

Description

[0001] This application generally relates to wireless communication, particularly 5G communication, 6G, or future wireless communication.

[0002] As the name implies, a low-power wake-up signal (LP-WUS) is used for energy saving. A wake-up receiver receives / monitors / detects the LP-WUS and sends a message to the main radio to wake it up. For a UE (User Equipment), the LP-WUS can be sent to the UE only when a paging from the gNB arrives at the UE and the UE may be woken up. Based on this, the UE can remain in sleep for most of the time and does not need to be woken up frequently to monitor signals (e.g., RRM (Radio Resource Management) measurement signals).

[0113] In the present disclosure, "based on" may be used synonymously with "according to".

[0114] It is well known that signals have greater performance degradation and poorer coverage performance in the high-frequency range and better coverage performance in the low-frequency range.

[0115] Due to the different designs of LP-WUS and SSB (synchronization signal / physical broadcast channel block), there may be significant performance differences between LP-WUS and SSB at the same frequency. To achieve comparable performance, LP-WUS may require repetition or other methods to obtain better coverage performance. However, in this case, the NW (network) resource overhead will be large, and the UE also needs to spend more time detecting LP-WUS. To provide sufficient coverage performance and save NW resource waste and UE power, the present disclosure provides a novel method, that is, to transmit LP-WUS at a low frequency. In addition, by simultaneously combining LP-WUS and SSB and / or other signals, the RRM measurement performance can be improved.

[0165] UE Behavior at Different Frequencies

In these embodiments, the first frequency of the first signal is different from or lower than the second frequency of the second signal.

[0174] In one embodiment, the paging PDCCH or PDSCH implicitly or explicitly indicates whether to transmit a fourth signal (e.g., PRACH / msgA).

[0175] In one embodiment, the process is determined based on a (metric) parameter of the first signal. For example, the (metric) parameter includes at least one of a correlation value, RSRP, RSRQ, RSSI, or any other metric or any (metric) parameter that reflects signal strength or quality.

[0176] In one embodiment, according to the metric or parameter of the first signal, if the metric or parameter is worse / greater / lower / smaller than a (threshold) value, the UE will process or will not process the second signal.

[0177] In one embodiment, according to the correlation value of the first signal, if the correlation value is below the (threshold) value, the UE may not receive the SSB / paging or transmit the PRACH.

[0178] In one embodiment, according to the correlation value of the first signal, if the correlation value is greater than the (threshold) value, the UE may receive the SSB / paging or transmit the PRACH.

[0179] In one embodiment, the correlation value is a parameter defined based on a correlation operation. For example, the correlation operation is based on autocorrelation, cross-correlation, or any defined formula.

[0180] In one embodiment, according to the RSRP, RSRQ, or RSSI value or the correlation value of the first signal, if the RSRP, RSRQ, or RSSI value or the correlation value is below the (threshold) value, the UE may not receive the third signal (e.g., SSB / paging) or transmit the fourth signal (e.g., PRACH).

[0181] In one embodiment, according to the RSRP, RSRQ, or RSSI value or the correlation value of the first signal, if the RSRP, RSRQ, or RSSI value or the correlation value of the first signal is greater than the (threshold) value, the UE may receive the third signal (e.g., SSB / paging) or transmit the fourth signal (e.g., PRACH).

[0182] In one embodiment, based on the difference of a related value, RSRP, RSRQ, or RSSI, if the difference of the related value, RSRP, RSRQ, or RSSI is worse / lower / smaller than a (threshold) value, the UE may receive a third signal, e.g., an SSB / paging, or transmit a fourth signal (e.g., a PRACH).

[0183] In one embodiment, based on the difference of a related value, RSRP, RSRQ, or RSSI, if the difference of the related value, RSRP, RSRQ, or RSSI is greater than a (threshold) value, the UE may receive a third signal (e.g., an SSB / paging) or transmit a fourth signal (e.g., a PRACH).

[0184] In one embodiment, based on the value of a defined metric parameter, if the value of the defined metric parameter is worse / greater / lower / smaller than a (threshold) value, the UE may or may not process a second signal. For example, the value of the defined metric parameter may be based on a related operation of one or more metrics / one or more parameters of a first signal.

[0185] In one embodiment, one or more thresholds are configured or predefined by the gNB.

[0186] In one embodiment, the process is determined based on a (metric) parameter of a first signal, where the parameter includes a difference / variance value. The difference / variance value may be based on a related value, RSRP, RSRQ, RSSI, or any (metric) parameter reflecting the change in signal strength or quality. For example, the difference / variance value may be the variance of a related value over a certain period, the variance of RSRP / RSRQ / RSSI over a certain period, or the variance of a parameter reflecting the change in signal strength or quality over a certain period.

[0187] In one embodiment, based on the difference of a first signal, if the difference is worse / greater / lower / smaller than a (threshold) value, the UE may or may not process a second signal.

[0188] For example, based on the difference of a related value, RSRP, RSRQ, or RSSI, if the difference is worse / lower / smaller than a (threshold) value, the UE may receive paging or the UE may transmit a PRACH / msgA.

[0189] For example, based on the difference of a related value, RSRP, RSRQ, or RSSI, if the difference is greater than a (threshold) value, the UE may receive an SSB.

[0190] In one embodiment, the process may be determined based on whether the UE receives a first signal.

[0191] For example, if the UE does not receive the first signal, the UE needs to process the second signal (e.g., receive SSB, CSI-RS, and / or TRS).

[0192] As an alternative or in addition, if the UE does not receive the first signal, the UE does not need to process the second signal (e.g., transmit PRACH).

[0193] As an alternative or in addition, if the UE does not receive the first signal, the UE does not need to process the second signal (e.g., transmit PRACH) within a duration.

[0194] In one embodiment, the process is determined based on whether the UE receives the first signal and / or whether the signal (metric) parameter of the first signal is greater than / lower than a threshold within a duration.

[0195] In one embodiment, the duration is based on a timer, a configuration from the gNB, a predefined one, or an indication carried by DCI (downlink control information).

[0196] For example, if the relevant value / RSRP / RSRQ / RSSI / defined parameter of the first signal is lower than the threshold within a duration, and / or if the UE does not receive the first signal within the duration, the UE needs to process the second signal (e.g., receive SSB, CSI-RS, and / or TRS).

[0197] As an alternative or in addition, if the relevant value / RSRP / RSRQ / RSSI / defined parameter of the first signal is greater than the threshold, the UE needs to process the second signal, e.g., transmit PRACH / msgA.

[0198] As an alternative or in addition, if the difference value of the relevant value / RSRP / RSRQ / RSSI / defined parameter of the first signal is greater than the threshold, and / or if the UE does not receive the first signal, the UE needs to process the second signal, e.g., receive SSB, CSI-RS, and / or TRS.

[0199] As an alternative or in addition, if the difference value of the relevant value / RSRP / RSRQ / RSSI / defined parameter of the first signal is less than the threshold, the UE needs to process the second signal, e.g., receive SSB, CSI-RS, TRS, paging, or transmit PRACH / msgA.

[0200] In one embodiment, the process is determined based on a predefined or configured portion of the first signal. For example, the process is determined based on whether the predefined / configured portion of the first signal is decoded / detected.

[0201] In one embodiment, the predefined / configured portion of the first signal may be certain defined overhead / bits (e.g., CRC bits, fields or at least one sequence, at least one preamble or the (first) N bits of the first signal (N is a positive integer)).

[0202] For example, if the CRC verification of the first signal fails, the UE needs to process the second signal, e.g., receive SSB, CSI-RS, and / or TRS.

[0203] As an alternative or in addition, if the field indicating the status is not decoded / detected / received, or if the field indicating the status is decoded / detected / received, the UE needs to process the second signal, e.g., receive SSB, CSI-RS, TRS, and / or transmit PRACH / msgA, receiver paging.

[0204] As an alternative or in addition, if the sequence or preamble is not decoded / detected / received, the UE needs to process the second signal, e.g., receive SSB, CSI-RS, and / or TRS.

[0205] As an alternative or in addition, if the sequence or preamble is decoded / detected / received, the UE needs to process the second signal, e.g., transmit PRACH / msgA.

[0206] In one embodiment, the sequence or preamble has the same modulation scheme as the first signal.

[0207] In one embodiment, the sequence or preamble and the first signal are continuous / adjacent in the time domain.

[0208] In one embodiment, the UE receives the first signal and performs the process of the second signal, where the process is determined based on the first signal and further based on the sequence, preamble, or reference signal.

[0209] In one embodiment, the determination of the process based on the first signal may be based on at least one of the above cases, i.e., based on the indication carried via the first signal, the (metric) parameter of the first signal, the missing part of the first signal, or whether the first signal is received.

[0210] In one embodiment, the process is also determined based on the sequence, preamble, or reference signal. For example, the process is determined based on the carried information and / or the detection / decoding / reception of the sequence, preamble, or reference signal.

[0211] In one embodiment, the UE receives a (low-power) synchronization reference signal and receives the first signal indicating the main radio wake-up. In this embodiment, the UE needs to process the second signal, e.g., receive the third signal and / or transmit the fourth signal.

[0212] In one embodiment, all UEs supporting the corresponding function / feature can decode / detect / receive (low-power) synchronization reference signals.

[0213] In one embodiment, the UE receives a sequence or a preamble and receives a first signal indicating the wake-up of the primary radio. In this case, the UE needs to process a second signal, e.g., receive a third signal and / or transmit a fourth signal.

[0214] In one embodiment, the sequence or the preamble can be decoded / detected / received by a group of UEs, multiple UEs, or at least one UE.

[0215] In one embodiment, the sequence or the preamble can be decoded / detected / received by one or more specific UEs. For example, the UE receives a paging message specific to the UE and receives a first signal with satisfactory (metric) parameters. In this case, the UE needs to process a second signal, e.g., receive a third signal and / or transmit a fourth signal.

[0216] In one embodiment, the UE receives a first signal and determines a process based on the first signal for a second signal. The first frequency of the first signal can be lower than the second frequency of the second signal, or the first frequency of the first signal can be different from the second frequency of the second signal. In this embodiment, a duration / delay is defined for the period after the UE receives the first signal. The UE can perform the process within or after the defined period.

[0217] That is, if the UE receives the first signal and the UE needs to process the second signal, the UE can process the second signal within or after the duration / delay after receiving the first signal.

[0218] For example, if the UE receives the first signal, the UE (can / needs to) perform the process of the second signal at least after the duration / delay.

[0219] In one embodiment, after X time units from when the UE receives the LP-WSU / LP-SS, the UE (can / needs to) receive a third signal (e.g., SSB and / or paging).

[0220] In one embodiment, after X time units from when the UE receives the LP-WSU / LP-SS, the UE (can / needs to) transmit a fourth signal (e.g., PRACH / msgA).

[0221] In one embodiment, X is a positive integer, and the time unit of the duration / delay can be a symbol, a time slot, a subframe, the basic time unit of NR Tc, or the basic time unit of the WUR (the WUR is used for receiving LP-WUS / LP-SS).

[0222] In one embodiment, the UE receives a first signal and determines a process for processing a second signal based on the first signal. In this embodiment, the first frequency of the first signal is lower than the second frequency of the second signal or the first frequency of the first signal is different from the second frequency of the second signal. For example, paging is configured at the first frequency, and the UE receives paging at the first frequency. Based on the paging (i.e., the first signal), the UE determines (and executes) a process for the second signal at the second frequency.

[0223] In one embodiment, the UE receives paging, paging PDCCH, or paging PDSCH at the first frequency. Based on an indication (implicit or explicit) carried by the paging or via the paging PDCCH or PDSCH, the UE needs to process a second signal, e.g., receive a third signal (e.g., SSB) at the second frequency.

[0224] In one embodiment, the UE receives paging at the first frequency. Based on an indication implicitly or explicitly carried by the paging via the paging PDCCH or PDSCH, the UE needs to process a second signal, e.g., transmit a fourth signal (e.g., PRACH / msgA) at the second frequency.

[0225] In one embodiment, the UE receives LP-SS / LP-WUS / sequence / preamble / SSB and paging at the first frequency. Based on an indication implicitly or explicitly carried by the paging via the paging PDCCH or PDSCH, and / or based on the detection / decoding / reception of the LP-SS / LP-WUS / sequence / preamble / SSB, the UE needs to process a second signal, e.g., transmit a fourth signal (e.g., PRACH / msgA) at the second frequency.

[0226] In one embodiment, the detection / decoding / reception of the LP-SS / LP-WUS / sequence / preamble / SSB is determined based on whether one or more (metric) parameters of the LP-SS / LP-WUS / sequence / preamble / SSB meet certain conditions (e.g., greater than / less than a corresponding threshold), or whether the LP-SS / LP-WUS / sequence / preamble / SSB is detected / decoded / received.

[0227] In one embodiment, the UE receives LP-SS / LP-WUS / sequence / preamble and paging at the first frequency. Based on an indication implicitly or explicitly carried by the paging via the paging PDCCH or PDSCH, and / or according to the detection / decoding / reception of the LP-SS / LP-WUS / sequence / preamble, the UE needs to process a second signal, e.g., receive a third signal (e.g., SSB) and / or transmit a fourth signal (e.g., PRACH / msgA) at the second frequency.

[0228] In one embodiment, the paging search space is configured at the first frequency by SIB1 / SIB.

[0229] In one embodiment, the UE receives a first signal and determines a process of a second signal based on the first signal. In this embodiment, a first resource for the first signal overlaps with a second resource for the second signal in the time domain and / or the frequency domain.

[0230] As an alternative or in addition, the first resource for the first signal and the second resource for the second signal are continuous / adjacent in the time domain and / or the frequency domain.

[0231] As an alternative or in addition, the first resource for the first signal overlaps with the second resource for the second signal in the time domain.

[0232] In one embodiment, the LP-WUS / LP-SS resource overlaps with the SSB in the time domain.

[0233] In one embodiment, the LP-WUS / LP-SS resource has the same occupied symbols as the SSB resource in the time domain.

[0234] In one embodiment, the first resource for the first signal and the second resource for the second signal are continuous / adjacent in the time domain.

[0235] For example, the LP-WUS / LP-SS resource and the SSB are continuous in the time domain.

[0236] As an alternative or in addition, the LP-WUS / LP-SS resource and the SSB have continuous / adjacent symbols in the time domain.

[0237] In one embodiment, the first resource for the first signal has an offset / gap from the second resource for the second signal in the time domain.

[0238] For example, the LP-WUS / LP-SS resource has an offset / gap from the SSB in the time domain. The offset / gap can be X ms (milliseconds), μs (microseconds), symbols, time slots, sub-frames, frames, any other time unit, including the basic time unit of NR Tc or the basic time unit of WUR.

[0239] In one embodiment, the first resource for the first signal overlaps with the second resource for the second signal in the frequency domain.

[0240] For example, the LP-WUS / LP-SS resource overlaps with the SSB in the frequency domain.

[0241] As an alternative or in addition, the LP-WUS / LP-SS resource has one or more occupied frequency resources (e.g., one or more REs or one or more RBs) that are the same as those of the SSB in the frequency domain.

[0242] In one embodiment, the first resource for the first signal and the second resource for the second signal are continuous / adjacent in the frequency domain.

[0243] For example, the LP-WUS / LP-SS resources and the SSB are continuous / adjacent in the frequency domain.

[0244] For example, the LP-WUS / LP-SS resources and the SSB have continuous / adjacent frequency resources (e.g., RB numbers) in the frequency domain.

[0245] In one embodiment, the first resource for the first signal and the second resource for the second signal have the same pattern / periodicity. The pattern can be equivalent to periodicity and offset.

[0246] In one embodiment, the first periodicity of the first resource of the first signal and the second periodicity of the second resource of the second signal have a multiple relationship.

[0247] For example, the position of the first signal in the time domain can be a subset of all positions of the second signal in the time domain, and vice versa.

[0248] In one embodiment, the first bandwidth of the first signal is not greater than the second bandwidth of the second signal.

[0249] In one embodiment, the first bandwidth of the first signal and the guard band are not greater than the bandwidth of the second signal and the guard band.

[0250] For example, the bandwidth of the LP-WUS / LP-SS resources and their guard band resources are not greater than the bandwidth of the SSB and the guard band resources.

[0251] In one embodiment, the bandwidth of the first signal and the guard band are greater than the bandwidth of the second signal and the guard band.

[0252] In one embodiment, the UE receives the first signal and determines (and executes) the process of the second signal based on the first signal. In this embodiment, the UE receives / monitors / detects / decodes the first signal and determines (whether / how) to transmit / report / feedback / send / trigger or activate the fourth signal.

[0253] In one embodiment, the fourth signal (e.g., PRACH / msgA) is non-periodic.

[0254] In one embodiment, the timing of the fourth signal is associated with the first signal. In other words, the first signal is associated with the timing of the fourth signal or mapped to the timing of the fourth signal.

[0255] For example, the PRACH occasion is associated with LP-WUS / LP-SS. That is, LP-WUS / LP-SS (resources) are mapped to or associated with the PRACH occasion.

[0256] For example, the PRACH occasion is associated with SSB or PSS / SSS or a signal based on PSS / SSS.

[0257] In one embodiment, the first signal and the third signal are associated with or mapped to the occasion of the fourth signal.

[0258] For example, LP-WUS / LP-SS and SSB are associated with or mapped to the PRACH occasion.

[0259] In one embodiment, the UE receives the first signal under specific conditions.

[0260] In one embodiment, these conditions include receiving a corresponding indication, which includes RRC indication, DCI indication, SIB (e.g., SIB1) indication, Mac indication. Note that the term "indication" can be replaced by "configuration".

[0261] In one embodiment, the indication can be a feature / parameter configured via RRC / SIB / Mac CE. That is, if / when the feature / parameter is configured via RRC / SIB / Mac CE, the UE receives the first signal.

[0262] In one embodiment, the indication is associated with a time period / duration or a timer configured via RRC / SIB / Mac CE. For example, if / when the time period / duration or the timer is configured via RRC / SIB / Mac CE, the UE may receive the first signal.

[0263] In one embodiment, these conditions include that one or more (metric) parameters of LP-SS / reference signal / sequence / preamble satisfy certain conditions (e.g., lower or greater than one or more corresponding thresholds).

[0264] In one embodiment, these conditions include whether to receive / detect / decode LP-SS / reference signal / sequence / preamble.

[0265] In one embodiment, if the (metric) parameter of LP-SS / reference signal / sequence / preamble is less than or greater than a threshold, the UE receives / monitors / detects the first signal.

[0266] For example, if the signal strength of LP-SS (e.g., RSRP) is greater than a threshold, the UE receives / monitors / detects LP-WUS / paging.

[0267] As an alternative or supplement, if the signal strength difference of the LP-SS is less than a threshold, the UE receives / monitors / detects the LP-WUS / paging.

[0268] As an alternative or supplement, if the LP-SS / reference signal / sequence / preamble is received / detected / decoded, the UE receives / monitors / detects the first signal.

[0269] As an alternative or supplement, if certain RRC signaling or SIB signaling is received / detected / decoded, the UE receives / monitors / detects the first signal.

[0270] In some embodiments, the UE may not receive the first signal under certain conditions.

[0271] In an embodiment, if / when the UE receives an indication from the gNB not to receive the first signal, the UE does not (need to) receive the first signal.

[0272] For example, the gNB indicates that the first signal (e.g., LP-WUS / LP-SS) is invalid / configured for the connected mode.

[0273] As an alternative or supplement, the signaling received via the gNB may indicate that the UE does not receive / detect / monitor / decode the first signal (e.g., LP-WUS / LP-SS).

[0274] For example, the gNB indicates that the UE does not need to receive / detect / monitor / decode the first signal (e.g., LP-WUS / LP-SS) within a duration / period.

[0275] In one embodiment, if / when the UE receives a signal from the gNB, the UE does not receive the first signal.

[0276] For example, the signal can be msg4 (in the random access procedure). When the UE (successfully) receives msg4 from the gNB, the UE does not receive the first signal, e.g., LP-WUS / LP-SS.

[0277] As an alternative, the signal is the third signal (e.g., paging / SSB).

[0278] In one embodiment, if / when the UE transmits a signal, the UE does not receive the first signal.

[0279] For example, after the UE transmits msg5, after the UE is in the connected mode, after the UE reports its capabilities, after the UE transmits the PRACH / msgA, and / or after the UE feeds back ACK / NACK, the UE does not receive the first signal (e.g., LP-WUS / LP-SS), or whether to receive the first signal depends on the UE (implementation).

[0280] In one embodiment, the UE receives a first signal and does not need to receive a third signal under certain conditions. These conditions include:

[0281] - If the (metric) parameter of the LP-SS / reference signal / sequence / preamble is less than or greater than a threshold, the UE does not receive the third signal (e.g., SSB).

[0282] - If the LP-WUS / LP-SS / reference signal / sequence / preamble is detected / monitored / received / configured / decoded, the UE does not receive the third signal (e.g., SSB).

[0283] - If in the connected mode: For example, a UE in the (RRC) connected mode receives the first signal and does not need to receive the third signal.

[0284] - gNB indication / signaling: For example, the UE receives the first signal and does not (need to) detect / monitor / receive / decode the third signal (e.g., SSB) according to the gNB indication / signaling (e.g., RRC signaling, DCI signaling, SIB signaling, or Mac signaling). The signaling can be activation signaling / deactivation signaling.

[0285] - Duration: For example, the UE receives the first signal within a duration and does not (need to) receive / detect / monitor / decode the third signal (e.g., SSB).

[0286] - Timer: For example, the UE receives the first signal and does not (need to) receive / detect / monitor / decode the third signal (e.g., SSB) according to a timer, e.g., before the timer expires.

[0287] In the present disclosure, LP-WUS refers to a low-power wake-up signal. LP-SS refers to a low-power synchronization signal.

[0288] In one embodiment, LP-WUS and LP-SS use the same modulation (e.g., OOK, ASK, FSK).

[0289] In one embodiment, LP-SS has a synchronization or measurement function.

[0290] In one embodiment, LP-WUS has the function of waking up the main radio.

[0301] Step 401: Receive a first signal from a second communication node.

[0302] Step 402: Determine a process of a second signal based on the first signal.

[0303] In Figure 4 Figure 4 , a first communication node receives a first signal from a second communication node and determines (and executes) a process for a second signal based on the first signal. Note that the determined process may be "not processing the second signal".

[0304] In one embodiment, the first signal includes at least one of at least one low power signal (e.g., LP-WUS or LP-SS), a paging channel (e.g., paging PDCCH, paging PDSCH, or paging occasion), a sequence, a reference signal, a downlink signal, or a downlink channel.

[0305] In one embodiment, the modulation of the low power signal is OFK, ASK, or FSK.

[0306] In one embodiment, the modulation of the low power signal may be OFDM-based modulation.

[0317] In one embodiment, a first communication node determines a second signal based on an indication carried by the first signal.

[0318] In one embodiment, the indication includes one or more bits, one or more preambles, one or more sequences, or one or more CRC bits. For example, the indication may include synchronization sequences (PSS and SSS).

[0319] In one embodiment, the first communication node determines the reception of a third signal or the transmission of a fourth signal, where the third signal is a downlink signal and the fourth signal is an uplink signal. In other words, based on the first signal, the first communication node may determine to receive the third signal (included in the second signal) and / or transmit the fourth signal.

[0320] In one embodiment, the timing of the fourth signal is associated with the first signal.

[0321] In one embodiment, the first communication node determines a second signal based on at least one parameter associated with the first signal. For example, the parameter on which the determination of the process is based may be a metric of the first signal (e.g., RSRP, RSRQ, RSSI, any metric associated with signal strength or signal quality or a metric associated with a change in the signal strength or signal quality of the first signal).

[0322] In one embodiment, if one of the at least one parameter is greater than, less than, not greater than, or not less than a threshold, the first communication node determines to execute the determined process.

[0323] In one embodiment, the threshold is configured or predefined by a second communication node, signaling, or downlink control information.

[0324] In one embodiment, if the parameter is greater than, less than, not greater than, or not less than the threshold within a period of time, the first communication node executes the process of the second signal.

[0325] In one embodiment, the period of time is indicated based on a timer, signaling from a second communication node, predefined, or downlink control information.

[0326] In one embodiment, the first communication node determines (and executes) a process of a second signal based on a predefined or configured portion of the first signal that the first communication node has not received.

[0327] In one embodiment, the first communication node determines (and performs) the procedure of the second signal based on a predefined or configured portion of the first signal that is absent in the received first signal.

[0328] In one embodiment, the predefined or configured portion includes at least one of a field, a sequence, a preamble, or N bits in the first signal, where N is a positive integer.

[0329] In one embodiment, the first communication node determines the procedure of the second signal based on the first signal and a fifth signal (e.g., a sequence, a preamble, or a reference signal) received from the second communication node.

[0330] In one embodiment, the first communication node performs the procedure within or after a time offset, a gap, or a duration after receiving the first signal.

[0331] In one embodiment, the first communication node receives the first signal from the second communication node at a first frequency in response to paging.

[0332] In one embodiment, the first communication node receives the first signal from the second communication node at a first frequency in response to paging and one of a low-power signal, a sequence, a preamble, or an SSB or a DL signal.

[0333] In one embodiment, the first signal overlaps with the second signal in the time domain and / or the frequency domain.

[0334] In one embodiment, the first signal and the second signal are continuous / adjacent in the time domain and / or the frequency domain.

[0335] In one embodiment, if at least one condition is satisfied, the first communication node receives the first signal from the second communication node. For example, the at least one condition includes at least one of the following:

[0336] At least one parameter associated with a low-power signal, a reference signal, a sequence, or a preamble satisfies at least one threshold condition,

[0337] Receiving a predefined / configured low-power signal, reference signal, sequence, or preamble, or

[0338] Receiving a reference signal, sequence, or preamble of a low-power signal.

[0339] In one embodiment, the UE does not receive the first signal under certain conditions. For example, under at least one of the following conditions, the UE does not (need to) receive the first signal:

[0340] - When / if the UE receives a corresponding indication from the BS (e.g., gNB);

[0341] - The gNB indicates that the first signal (e.g., LP-WUS / LP-SSS) is invalid / configured for the connected mode, and the UE is in the connected mode;

[0342] - Signaling received from / via the BS (e.g., gNB) indicates that the UE does not (need to) receive / detect / monitor / decode the first signal (e.g., LP-WUS / LP-SSS);

[0343] - The gNB indicates that for a duration / period, the UE does not need to receive / detect / monitor / decode the first signal (e.g., LP-WUS / LP-SSS);

[0344] - When / If the UE receives a signal from the BS:

[0345] For example, the signal is msg4 (in the random access procedure). In this example, the UE (successfully) receives msg4 from the BS and does not (need to) receive the first signal (e.g., LP-WUS / LP-SSS). Alternatively, the signal is the third signal (e.g., paging / SSB).

[0346] - When / If the UE transmits a signal, which may include at least one of msg5 (in the random access procedure), UE capability report, PRACH, msgA, or ACK / NACK.

[0347] For example, after the UE transmits msg5 (in the random access procedure), after the UE is in the connected mode, after the UE transmits a capability report, after the UI transmits PRACH / msgA, or after the UE feeds back ACK / NACK, the UE does not (need to) receive the first signal (e.g., LP-WUS / LP-SS), or whether the UE receives the first signal depends on the UE (implementation).

[0348] In one embodiment, if at least one condition is met, the first communication node determines not to receive the third signal included in the second signal. In this embodiment, at least one condition includes at least one of the following:

[0349] At least one parameter associated with the first signal meets at least one threshold condition,

[0350] The first signal is received,

[0352] Downlink control information for the connected mode is received, or

[0353] An indication is received via the first signal, SIB, MAC CE, or RRC signaling / parameters.

[0354] For example, if the (metric) parameter of the LP-SS / reference signal / sequence / preamble is less than or greater than a threshold, the UE does not receive the third signal (e.g., SSB).

[0355] For example, if the LP-WUS / LP-SS / reference signal / sequence / preamble is detected / monitored / received / configured / decoded, the UE does not receive the third signal (e.g., SSB).

[0356] For example, the first communication node is in the connected mode. In the connected mode, the UE receives the first signal and does not receive the third signal.

[0357] For example, according to an indication / signaling from the BS (e.g., gNB), the UE receives the first signal and does not receive / detect / monitor / decode the third signal (e.g., SSB). In one embodiment, the indication from the BS may be RRC signaling, DCI signaling, SIB signaling, or Mac signaling. In one embodiment, the signaling may be activation signaling / deactivation signaling.

[0358] For example, according to a duration, the UE receives the first signal and does not receive / detect / monitor / decode the third signal during that duration. That is, within the duration after receiving the first signal, the UE does not receive / detect / monitor / decode the third signal.

[0359] For example, according to a timer, the UE receives the first signal and does not receive / detect / monitor / decode the third signal (e.g., SSB). In one embodiment, the timer is triggered / activated / started in response to the reception of the first signal. Before the timer expires, the UE does not receive the third signal.
