BACKGROUND
In fourth generation (4th Generation, 4G) and fifth generation (5th Generation, 5G) communications systems, in order to further reduce power consumption of blind detection of a paging (Paging) signal, or power consumption of blind detection of a physical downlink control channel (Physical Downlink Control Channel, PDCCH), for a discontinuous reception (Discontinuous Reception, DRX) scenario, concepts of wake-up signal (wake-up signal, WUS) and go-to-sleep signal (Go To Sleep Signal, GTS) are proposed. Detection of the WUS or the GTS is less complex and more power efficient, as compared with blind detection of the paging signal or the PDCCH.

DETAILED DESCRIPTION
Exemplary embodiments of the present disclosure are described in more detail with reference to the accompanying drawings hereinafter. Although the drawings show exemplary embodiments of the present disclosure, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
Terms such as “first” and “second” in the specification and the claims of the present disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way may be interchanged under appropriate circumstances, so that the embodiments of the present application described herein may be implemented in a sequence other than those illustrated or described herein. In addition, terms such as “including” and “having” and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the steps or units that are clearly listed and may include other steps or units that are not clearly listed or are inherent to the process, method, product, or device.
In 4G and 5G communication systems, a user equipment in a radio resource control idle (Radio Resource Control idle, RRC idle) state needs to detect at a pre-configured time a paging signal sent by a network device. The specific process for the paging signal includes: performing blind detection for a PDCCH corresponding to a paging radio network temporary identity (Paging Radio Network Temporary Identity, P-RNTI); if the PDCCH is not detected, ending this detection; if the PDCCH is detected, detecting a physical downlink shared channel (Physical Downlink Share Channel, PDSCH) indicated by the PDCCH, and if the detected PDSCH is not the paging signal of the user equipment, ending the detection. In the RRC idle state, the user equipment periodically performs detection of the paging signal, power consumption at each detecting of the PDCCH and the PDSCH is large, and the probability of the case where the detected paging signal belongs to the user equipment is low, which is not conducive to power saving of the user equipment.
In a discontinuous reception (Discontinuous Reception, DRX) scenario, the basic mechanism of DRX is as follows: a DRX cycle is configured for a user equipment in a connected (RRC_connected) state, as shown in FIG. 1 which is a schematic diagram of a time domain of a DRX cycle; the DRX cycle includes on duration (On Duration) and opportunity for DRX (Opportunity for DRX); the user equipment monitors and receives the PDCCH during the on duration, and the user equipment does not receive data of the downlink channel during the opportunity for DRX to reduce power consumption. In other words, in the time domain, the time is divided into successive DRX cycles. The DRX start offset (drxStartOffset) is used to indicate the start subframe of the DRX cycle, and the long DRX cycle (longDRX-Cycle) is used to indicate how many subframes are occupied by the long DRX cycle. These two parameters are determined by the longDRX-CycleStartOffset field. The on duration timer (On Duration Timer) specifies the number of consecutive subframes (that is, the number of subframes for which the on duration lasts) in which the PDCCH needs to be monitored, starting from the start subframe of the DRX cycle.
In most cases, after a user equipment is scheduled to receive or transmit data in a certain subframe, it is likely to continue to be scheduled in the next several subframes. If it waits for the next DRX cycle to perform reception or transmission, these pieces of data may bring additional latency. In order to reduce such latency, the user equipment continues being in the active period after being scheduled, that is, it continues monitoring the PDCCH during the configured active period. Specifically, when the user equipment is scheduled to initially transmit data, an inactivity timer (drx-InactivityTimer) is started or restarted, and the user equipment is always in the active period when the timer does not expire. Drx-InactivityTimer specifies, the number of consecutive subframes of continuously being in the active state after the user equipment successfully decodes the PDCCH indicating the initially transmitted uplink (Uplink, UL) or downlink (Downlink, DL) user data. That is, the timer is restarted each time the user equipment has initial transmission data to be scheduled.
Some embodiments of the present disclosure provide a method for detecting information, which is operable by a user equipment. As shown in FIG. 2, the method includes steps 21 to 22.
Step 21 includes: obtaining a time gap between a first occasion and a second occasion.
The first occasion is an occasion of an early indication signal, and the second occasion is an occasion of a physical downlink control channel (PDCCH) corresponding to the early indication signal. The early indication signal includes at least one of: a wake-up signal (WUS) or a go-to-sleep signal (GTS). The first occasion or the second occasion is configured by a network device for the user equipment, or, the first occasion or the second occasion is determined by the user equipment based on identification information of the user equipment.
In order to further reduce power consumption of blind detection for the paging signal or the PDCCH in the DRX scenario, the concepts of WUS and GTS are proposed, where the WUS and the GTS are collectively referred to as early indication signals. In each DRX cycle in the idle state or the RRC connected state, or in the RRC connected state (e.g., DRX OFF), before the user equipment performs the blind detection for the paging signal or the PDCCH, the network device transmits a WUS to the user equipment, and the user equipment wakes up at the corresponding time to detect the WUS. If the WUS is detected by the user equipment, the user equipment performs the blind detection for the paging signal or the PDCCH; otherwise, the user equipment does not perform the blind detection for the paging signal or the PDCCH, and continues to sleep. As shown in FIG. 3, it is assumed that the user equipment can detect the WUS in the physical channel when the network device configures the WUS for the user equipment; if the WUS is detected, it is determined that PDCCH detection is required in the next DRX cycle; if the WUS is not detected, it is determined that PDCCH detection is not required in the next DRX cycle and the sleep state is continued. Or, in each DRX cycle in the idle state or the RRC connected state, before the user equipment performs the blind detection for the paging signal or the PDCCH, the network device may transmit a GTS to the user equipment, and the user equipment wakes up at the corresponding time to detect the GTS. If the GTS is detected by the user equipment, the user equipment does not perform the blind detection for the paging signal or the PDCCH, and continues to sleep; otherwise, the user equipment performs the blind detection for the paging signal or the PDCCH. Detection of the WUS or the GTS is less complicated and more power efficient, as compared with blind detection of the paging signal or the PDCCH.
Further, the early indication signal may be with discontinuous transmission (Discontinuous Transmission, DTX) or without DTX. A case of being with DTX is taken as an example: in a case that the early indication signal carries a WUS sequence, it is determined that PDCCH detection is required in the next DRX cycle if the WUS sequence is detected by the user equipment, and it is determined that PDCCH detection is not required in the next DRX cycle if the WUS sequence is not detected; similarly, in a case that the early indication signal carries a GTS sequence, it is determined that PDCCH detection is required in the next DRX cycle if the GTS sequence is not detected, and it is determined that PDCCH detection is not required in the next DRX cycle if the GTS sequence is detected. A case of being without DTX is taken as an example: in a case that the early indication signal carries a WUS sequence, it is determined that the corresponding PDCCH needs to be detected in the next DRX cycle if the WUS sequence is detected as a first sequence format, and it is determined that there is no need to detect the corresponding PDCCH in the next DRX cycle and the user equipment continues to sleep if the WUS is detected as a second sequence format; similarly, in a case that the early indication signal carries a GTS sequence, it is determined that the corresponding PDCCH needs to be detected in the next DRX cycle if the GTS sequence is detected as a third sequence format, and it is determined that there is no need to detect the corresponding PDCCH in the next DRX cycle and the user equipment continues to sleep if the GTS is detected as a fourth sequence format.
In the idle state, the time gap between the first occasion and the second occasion can be: a time interval between an occasion of the WUS and an occasion of the paging signal corresponding to the WUS, that is, a time gap between the WUS and the paging occasion (Paging Occasion, PO). In the RRC_connected state, the time gap between the first occasion and the second occasion can be: a time gap between an occasion of the WUS (such as a slot or a subframe where it is located) and an occasion of the PDCCH (such as a slot or a subframe where it is located) corresponding to the WUS.
Step 22 includes: determining, based on the time gap, the occasion of the early indication signal or the occasion of the PDCCH corresponding to the early indication signal.
Step 22 may be implemented in, but not limited to, the following manners.
The first manner includes: determining the occasion of the PDCCH corresponding to the early indication signal based on the first occasion and the time gap, in a case that the first occasion is determined.
The first occasion is configured by the network device for the user equipment, or the first occasion is determined by the user equipment based on the identification information (UE ID) of the user equipment. That is, the user equipment determines the occasion of detecting the PDCCH corresponding to the early indication signal based on the time gap and the occasion of the early indication signal, wherein the occasion of the early indication signal is configured by the network device or determined by the user equipment based on the UE ID.
The second manner includes: determining the occasion of the early indication signal based on the second occasion and the time gap, in a case that the second occasion is determined.
The second occasion is configured by the network device for the user equipment, or the second occasion is determined by the user equipment based on the identification information (UE ID) of the user equipment. That is, the user equipment determines the occasion of detecting the early indication signal based on the time gap and the occasion of the PDCCH corresponding to the early indication signal, where the occasion of the PDCCH corresponding to the early indication signal is configured by the network device or determined by the user equipment based on the UE ID.
In an embodiment, after step 22, the method further includes: detecting the early indication signal at the determined occasion of the early indication signal, or detecting the PDCCH at the determined occasion of the PDCCH corresponding to the early indication signal.
It should be noted that, the step of detecting the early indication signal at the determined occasion of the early indication signal is performed in a case that only the occasion of the early indication signal is determined in step 22, and the step of detecting the PDCCH at the determined occasion of the PDCCH corresponding to the early indication signal is performed in a case that only the occasion of the PDCCH corresponding to the early indication signal is determined in step 22.
Optionally, the step of determining the occasion of the early indication signal includes: determining a start time or an end time of a maximum duration of the early indication signal, or, determining a start time or an end time of an actual duration of the early indication signal.
The network device may configure a group of actual durations for the early indication signal of the user equipment, where the group of actual durations includes at least one actual duration. The network device may configure a limited number of durations (WUS actual duration) for all user equipments in a cell, for example, the number of repetitions is 1, 10, or 100. The actual duration has only one possible position (the only position) within the maximum duration, that is, there is a first duration between the start time of the actual duration of the early indication signal and the start time of the longest duration of the early indication signal, where the first duration is greater than or equal to 0 time domain transmission unit. When the first duration is 0 time domain transmission unit, the start time of the actual duration of the early indication signal is the same as the start time of the longest duration (i.e., coinciding). Or, there is a second duration between the end time of the actual duration of the early indication signal and the end time of the longest duration of the early indication signal, where the second duration is greater than or equal to 0 time domain transmission unit. When the second duration is 0 time domain transmission unit, the end time of the actual duration of the early indication signal is the same as the end time of the longest duration (i.e., coinciding). The number of the actual duration is at least one, and the start time of each of the at least one actual duration is the same as the start time of the maximum duration of the early indication signal; or, the number of the actual duration is at least one, and the end time of each of the at least one actual duration is the same as the end time of the maximum duration.
In a case that the number of the actual duration is at least two, after the step of determining the start time or the end time of the actual duration of the early indication signal, the method further includes: performing blind detection in the at least two actual durations. That is, in a case that the network device configures a group of actual durations for the early indication signal of the user equipment, after determining the start time or the end time of the early indication signal, the user equipment may perform blind detection in the various possible actual durations based on the start time or the end time of the early indication signal.
In some optional embodiments, the first occasion is the start time or the end time of the maximum duration of the early indication signal, that is, the occasion of the early indication signal is the start time or the end time of the maximum duration of the early indication signal, where the maximum duration of the early indication signal is explained as follows. In order to improve the transmission reliability of the early indication signal, different numbers of repetitions of the early indication signal may be set for different user equipments or cells; the different numbers of repetitions are realized based on repeatedly transmitting time domain transmission unit(s) in the time, and the time domain transmission unit(s) may be a frame, a subframe (subframe), a slot (slot) or a time domain symbol (an OFDM symbol). For example, for a user equipment in the center a cell, the number of repetitions for the early indication signal is 1, and for a user equipment at the edge of the cell, the number of repetitions for the early indication signal is 100. The higher the number of repetitions for a signal is, the better the coverage performance of the signal is. The duration corresponding to the maximum number of repetitions for the early indication signal is the maximum duration (maximum duration) of the early indication signal. The maximum duration of the early indication signal determines the coverage area of the cell, and the maximum duration of the early indication signal is notified to the user equipment through a system information block (SIB) message.
Or, the first occasion is the start time or the end time of the actual duration of the early indication signal, that is, the occasion of the early indication signal is the start time or the end time of the actual duration of the early indication signal. The duration corresponding to the actual number of repetitions of the early indication signal is the actual duration (actual duration) of the early indication signal. The actual duration has only one possible position (the only position) within the maximum duration, that is, there is a first duration between the start time of the actual duration of the early indication signal and the start time of the longest duration of the early indication signal, where the first duration is greater than or equal to 0 time domain transmission unit. When the first duration is 0 time domain transmission unit, the start time of the actual duration of the early indication signal is the same as the start time of the longest duration (i.e., coinciding). Or, there is a second duration between the end time of the actual duration of the early indication signal and the end time of the longest duration of the early indication signal, where the second duration is greater than or equal to 0 time domain transmission unit. When the second duration is 0 time domain transmission unit, the end time of the actual duration of the early indication signal is the same as the end time of the longest duration (i.e., coinciding).
In an optional embodiment, the network device may configure a group of actual durations for the early indication signal of the user equipment, where the group of actual durations includes at least one actual duration. The network device may configure a limited number of durations (WUS actual duration) for all user equipments in a cell, for example, the number of repetitions is 1, 10, or 100. The network devices may notify the several WUS actual durations in the above to the user equipment through signaling such as RRC signaling. One WUS repetition occupies all OFDM symbols or part of OFDM symbols of a slot or a subframe in the time, such as occupying the last 11 OFDM symbols of a subframe. Multiple WUS repetitions occupy continuous or non-continuous slots or subframes. Further, in the embodiment, the start time of the actual duration of the early indication signal coinciding with the start time of the longest duration of the early indication signal refers to that: the start time of each actual duration among the various actual durations coincide with the start time of the maximum duration of the early indication signal. Similarly, the end time of the actual duration of the early indication signal coinciding with the end time of the longest duration of the early indication signal refers to that: the end time of each actual duration among the various actual durations coincides with the end time of the maximum duration of the early indication signal.
In some optional embodiments, the second occasion is a start time or an end time of time domain transmission unit(s) where the PDCCH is located, where the time domain transmission unit(s) includes any of the following: a frame, a subframe, a slot, or a time domain symbol (an OFDM symbol). In other words, the occasion of the PDCCH is the start time or the end time of the OFDM symbol, slot, subframe, or frame where the PDCCH is located.
Optionally, a duration of the time gap is related to at least one of the following:
A type of a receiver that receives the early indication signal. The type of the receiver includes a main receiver and a non-main receiver (or referred to as other receiver, dedicated receiver). That is, the corresponding duration of the time gap for a case where the user equipment uses the independent non-main receiver to receive the early indication signal is different from the corresponding duration of the time gap for a case where the user equipment uses the main receiver receive the early indication signal. When the user equipment adopts the independent non-main receiver to receive the early indication signal, the main receiver is used to receive other signals except the early indication signal. Optionally, if the early indication signal is received by the independent receiver (the non-main receiver), then the user equipment may make some optimizations for energy saving, for example, the independent receiver only supports a small bandwidth, and some modules are deleted, etc.; and the main receiver is used to receive signals other than the early indication signal. If the user equipment receives the early indication signal and the PDCCH corresponding to the early indication signal via the main receiver, the user equipment does not need to perform RF retuning, so that the time gap can be shorter. When different receivers are used, the values of the determined time gaps are also different. Optionally, the user equipment may report both the value of the time gap and whether the WUS is supported
A preset behavior of the user equipment. The preset behavior includes: the user equipment performing downlink synchronization only based on the early indication signal, or, the user equipment performing downlink synchronization based on the early indication signal and a synchronous signal block (Synchronous Signal Block, SSB), or, the user equipment performing downlink synchronization only based on a synchronous signal block. That is, the time gap is related to the preset behavior of the user equipment. The preset behavior includes: the user equipment performing downlink synchronization only based on WUS or GTS, or, the user equipment performing downlink synchronization based on WUS, GTS and SSB, or, the user equipment performing downlink synchronization only based on SSB. The user equipment performing downlink synchronization only based on the SSB includes two situations: the user equipment performing downlink synchronization based on the SSB before receiving WUS, and the user equipment performing downlink synchronization based on the SSB after receiving WUS and before receiving PDCCH. The above SSB is only for the NR system, but other systems are not excluded for this embodiment. Specifically, this embodiment includes: in the NB-IoT system, the user equipment performs downlink synchronization based on NPSS/NSSS (Narrowband Primary Synchronization Signal/Narrowband Secondary Synchronization Signal); in the LTE system or MTC system, the user equipment performs downlink synchronization based on PSS/SSS (Primary Synchronization Signal/Secondary Synchronization Signal); in the 5G NR (New Radio) system, the user equipment performs downlink synchronization based on SSB. In an embodiment, the time gap is related to the behavior of the UE, and the behavior includes: the user equipment performing downlink synchronization based on WUS, or the user equipment periodically performing downlink synchronization based on SSB. If the user equipment only uses WUS to perform downlink synchronization, and if the network device sends DTX for several consecutive paging cycles, then in the subsequent the time for downlink synchronization may be relatively long when the user equipment receives non-DTX WUS, resulting in increased time gap between WUS and PDCCH corresponding to the WUS; if the user equipment periodically performs downlink synchronization based on SSB, the user equipment may flexibly set the size of the period to maintain good downlink synchronization, and in the subsequent the time for downlink synchronization may be relatively short when the user equipment receives non-DTX WUS, resulting in increased time gap between WUS and PDCCH corresponding to the WUS. Therefore, when the behaviors of the user equipment are different, the values of the time gaps reported by the user equipment are also different. The user equipment performing downlink synchronization only based on SSB includes two situations: the user equipment performing downlink synchronization based on the SSB before receiving WUS, and the user equipment performing downlink synchronization based on the SSB after receiving WUS before receiving PDCCH.
A frequency domain transmission resource of the early indication signal, and a frequency domain transmission resource of the PDCCH corresponding to the early indication signal. In other words, the time gap is related to the frequency domain resource of the user equipment receiving WUS or GTS and the frequency domain resource of the user equipment receiving PDCCH. In an embodiment, the time gap corresponding to a case where the center frequency of the frequency domain resource of the user equipment for receiving WUS or GTS is different from the center frequency of the frequency domain resource of the user equipment for receiving PDCCH, is longer than, the time gap corresponding to a case where the center frequency of the frequency domain resource of the user equipment for receiving WUS or GTS is the same as the center frequency of the frequency domain resource of the user equipment for receiving PDCCH; the frequency domain resource may be a bandwidth part (Bandwidth Part, BWP), a bandwidth (bandwidth) or a channel (channel). The time for radio frequency retuning (Radio Frequency retuning, RF retuning) corresponding to a case where the center frequency of the frequency domain resource of the user equipment for receiving WUS or GTS is different from the center frequency of the frequency domain resource of the user equipment for receiving PDCCH, is longer than, the time for RF retuning corresponding to a case where the center frequency of the frequency domain resource of the user equipment for receiving WUS or GTS is the same as the center frequency of the frequency domain resource of the user equipment for receiving PDCCH, hence, the time gap corresponding to the case where the center frequencies are different is longer than the time gap corresponding to the case the center frequencies are the same.
The time gap is determined by the user equipment, or, the time gap is configured by the network device for the user equipment, or, the time gap is predefined by a protocol. Specifically, the time gap includes at least one of: a first time gap determined by the user equipment, a second time gap configured by the network device for the user equipment, or, a third time gap predefined by the protocol.
Based on different ways of determining the time gap, the following scenarios are further illustrated in some embodiments of the present disclosure.
In the first scenario: the time gap only includes the first time gap, that is, the time gap is determined by the user equipment itself.
In this scenario, the user equipment may determine the length of the time gap based on at least one of the following: the type of receiver that receives the early indication signal, the preset behavior of the user equipment; the frequency domain transmission resource of the early indication signal and the frequency domain transmission resource of the PDCCH corresponding to the early indication signal.
After the user equipment determines the first time gap, it reports the first time gap to the network device. The first time gap reported by the user equipment may be reported by 1 bit. For example, 0 represents that the first time gap is 10 ms (the receiver that receives the WUS is the main receiver), and 1 represents that the first time gap is 30 ms (the receiver that receives the WUS is the separate non-main receiver). Or, the first time gap reported by the user equipment may be reported by 2 bits. For example, 00 represents that the first time gap is 10 ms (the WUS is received by the main receiver, and the UE supports periodic downlink synchronization through SSB); 01 represents that the first time gap is 20 ms (the WUS is received by the main receiver and the user equipment does not support periodic downlink synchronization through SSB; or, the WUS is received by the main receiver, the user equipment supports periodic downlink synchronization through SSB, and the period is very long; or, the WUS is received by the main receiver and the user equipment only supports downlink synchronization through WUS); 10 represents that the first time gap is 40 ms (the receiver that receives the WUS is the separate receiver and the UE supports periodic downlink synchronization through SSB); 11 represents that the first time gap is 80 ms (the receiver that receives the WUS is the separate receiver and the user equipment does not support periodic downlink synchronization through SSB; or, the receiver that receives the WUS is the separate receiver, the UE supports periodic downlink synchronization through SSB, and the period is very long; or, the receiver that receives the WUS is the separate receiver and only downlink synchronization through WUS is supported).
In the second scenario2: the time gap includes only the second time gap, that is, the time gap is configured by the network device for the user equipment.
In this scenario, the network device may determine and configure for the user equipment the length of the time gap based on at least one of the following: the type of receiver that receives the early indication signal, the preset behavior of the user equipment; the frequency domain transmission resource of the early indication signal and the frequency domain transmission resource of the PDCCH corresponding to the early indication signal.
In this scenario, before the network device determines the time gap, the user equipment reports the type of the receiver receiving the early indication signal and the preset behavior of the user equipment (or the behavior capability of the user equipment) to the network device, so that the network device may determine the duration of the time gap.
Optionally, the network device determines the maximum value among different first time gaps related to user equipments with different capabilities as the second time gap, and notifies the user equipment of the second time gap.
Optionally, the time gap is configured by the network device for one user equipment or a group of user equipments through preset signaling, where the preset signaling includes at least one of: broadcast signaling, radio resource control (RRC) signaling, media access control (Media Access Control, MAC) control element (Control Element, CE), or a PDCCH. The broadcast signaling includes: a master information block (Master Information Block, MIB), a system information block (System Information Block, SIB), etc.
In another optional embodiment, after step 21, the method further includes: determining a target synchronization manner for downlink synchronization based on the time gap. The target synchronization manner includes: performing downlink synchronization based on the early indication signal, or, performing downlink synchronization based on the early indication signal and a synchronous signal block, or, performing downlink synchronization based on a synchronous signal block. In other words, when the time gap is the second time gap configured by the network device, the user equipment may determine the related behavior based on the second time gap; for example, the user equipment performs downlink synchronization through WUS or GTS, or, the user equipment periodically performs downlink synchronization through SSB, or, the user equipment performs downlink synchronization through combination of WUS or GTS with SSB.
Specifically, when the values of the second time gaps configured by the network device for the user equipment are different, the behavior of the user equipment are also affected. If the time gap between the WUS and the PDCCH corresponding to WUS, configured by the network device for the user equipment, is relatively long, if the user equipment may only performs downlink synchronization through WUS, even if the network device sends DTX consecutively for several paging cycles, then in the subsequent the time for downlink synchronization may be relative abundant when the user equipment receives non-DTX WUS. If f the time gap between the WUS and the PDCCH corresponding to WUS, configured by the network device for the user equipment, is relatively short, then the user equipment may periodically perform downlink synchronization through SSB (SS block), and the user equipment may flexibly set the size of the period to maintain good downlink synchronization, so that in the subsequent the time for downlink synchronization when the user equipment receives non-DTX WUS will not exceed the second time gap configured by the base station for the user equipment.
In the third scenario: the time gap includes the first time gap and the second time gap, that is, the time gap is the second time gap configured by the network device for the user equipment based on the first time gap.
In this scenario, the user equipment may determine the length of the first time gap based on at least one of the following: the type of receiver that receives the early indication signal, the preset behavior of the user equipment; the frequency domain transmission resource of the early indication signal and the frequency domain transmission resource of the PDCCH corresponding to the early indication signal.
After the user equipment determines the first time gap, it reports the first time gap to the network device. The reporting manner thereof may be the manner in the first scenario, which is not repeated herein. After obtaining the first time gap, the network device configures the second time gap for the user equipment with reference to the first time gap. For the manner in which the network device sends the second time gap to the user equipment, reference can be made to the indication manner in the second scenario, which is not repeated herein.
Optionally, the network device determines the maximum value among different first time gaps reported by different user equipments as the second time gap, and notifies the user equipment of the second time gap. For example, if some user equipments report a time gap of 10 ms, and other user equipments report a time gap of 30 ms, then the network device configures the second time gap to be 30 ms, which can meet the needs of all user equipments.
In the fourth scenario: the time gap includes the third time gap, that is, the time gap is predefined by the protocol.
In this scenario, the time gap is a fixed duration predefined by the protocol. For example, the time gap is predefined by the protocol as M time domain transmission units, such as subframes, slots, or OFDM symbols, then, after the occasion of the early indication signal is determined, the occasion of the PDCCH corresponding to the early indication signal may be determined based on the occasion of the early indication signal and the M time domain transmission units. Similarly, after determining the occasion of the PDCCH corresponding to the early indication signal, the occasion of the early indication signal may be determined based on the occasion of the PDCCH corresponding to the early indication signal and the M time domain transmission units.
Optionally, the second time gap predefined by the protocol is the maximum value among different first time gaps related to user equipments with different capabilities. For example, some user equipments support a time gap of 10 ms, and other user equipments support a time gap of 30 ms, then, the protocol predefines the second time gap as 30 ms, which can meet the needs of all user equipments.
In another optional embodiment, after step 21, the method further includes: determining a target synchronization manner for downlink synchronization based on the time gap. The target synchronization manner includes: performing downlink synchronization based on the early indication signal, or, performing downlink synchronization based on the early indication signal and a synchronous signal block, or, performing downlink synchronization based on a synchronous signal block. In other words, when the time gap is the third time gap defined by the protocol, the user equipment may determine the related behavior based on the third time gap; for example, the user equipment performs downlink synchronization through WUS or GTS, or, the user equipment periodically performs downlink synchronization through SSB, or, the user equipment performs downlink synchronization through combination of WUS or GTS with SSB.
The method for detecting information according to some embodiments of the present disclosure are described in the above, which are further described with reference to the drawings and specific implementations hereinafter.
A first embodiment is directed to the first manner in the above, i.e., the scene where the occasion of the early indication signal is known.
The user equipment determines the occasion of detecting the PDCCH corresponding to the early indication signal based on the time gap and the occasion of the early indication signal (i.e., the first occasion). The occasion of the early indication signal is configured by the network device or determined based on the UE ID. The PDCCH corresponding to the early indication signal is a PDCCH that the early indication signal instructs the user equipment to detect.
The user equipment may calculate the occasion of early indication signal based on the UE ID. Specifically, the identification information (UE ID) of the user equipment is mapped to N downlink slots, subframes or frames (N>0) through a certain function such as a hash function. The UE ID includes International Mobile Subscriber Identity (International Mobile Subscriber Identity, IMSI), Packet-Temporary mobile subscriber identification (Packet-Temporary mobile subscriber identification, P-TMS), Temporary mobile subscriber identification (Temporary mobile subscriber identification, TMS), or a short format.
The first occasion is the start time or the end time of the maximum duration of the early indication signal, and the duration corresponding to the maximum number of repetitions for the early indication signal is the maximum duration (maximum duration) of the early indication signal. The maximum duration of the early indication signal determines the coverage area of the cell, and the maximum duration of the early indication signal is notified to the user equipment through a system information block (SIB) message.
Or, the first occasion is the start or the end time of the actual duration of the indication signal in advance, and the network device may configure a limited number of durations (WUS actual duration) for all user equipments in a cell, and notify them to the user equipments through signaling such as RRC signaling.
In an optional embodiment, the network device may not notify the UE of the actual duration of the early indication signal of the UE, such as WUS actual duration. In order to reduce the complexity of detecting WUS for the user equipment, the user equipment may perform blind detection for each type of actual duration of the WUS for only one time, and for each type of WUS actual duration, detection is performed from the first subframe of the WUS. For example, the network device informs the UE that there are three types of WUS actual durations in the cell, such as the numbers of repetitions of WUS being 1, 10, and 100 respectively. The start subframe of WUS actual duration is subframe #0 of radio frame #0, which coincides with the start subframe of WUS maximum duration. The user equipment, in turn, performs WUS detection on subframe #0 of radio frame #0; performs WUS detection on 10 subframes from subframe #0 to subframe #9 of radio frame #0 (when detection is performed on the 10 subframes, the user equipment stops detecting in a case that the user equipment successfully detects the wake-up signal through N (N>1, N<10, and N is an integer) subframes thereof); and performs WUS detection on 100 subframes from subframe #0 of radio frame #0 to subframe #99 of radio frame #9 (when detection is performed on the 100 subframes, the user equipment stops detecting in a case that the user equipment successfully detects the wake-up signal through N (N>1, N<100, and N is an integer) subframes thereof). The above detection sequence may be adjusted; if WUS is successfully detected in a certain detection, the user equipment stops blind detection. Subframes #0 to #99 are the numbers of consecutive subframes that can transmit WUS. Or, the subframes for transmitting WUS may be inconsecutive. The above-mentioned subframe may be replaced by a slot or an OFDM symbol.
Or, WUS actual duration is indicated by a WUS sequence. Specifically, different WUS sequences (such as multiple different root sequences, or multiple sequences with different scrambling sequences, or multiple sequences generated by different cyclic shifts) correspond to different WUS actual durations respectively.
As shown in FIG. 4, T1 is the start time of the actual duration of the early indication signal, and T1 is also the start time of the maximum duration of the early indication signal, that is, the start time of the maximum actual duration of the early indication signal coincides with the start time of the maximum duration of the early indication signal. T2 is the end time of the actual duration of the early indication signal. T3 is the end time of the maximum duration of the early indication signal. T4 is the start time of the PDCCH corresponding to the early indication signal. T5 is the end time of the PDCCH corresponding to the early indication signal. Then, the time gap may be any of the three situations in FIG. 4, i.e., time gap G1=T4−T3, or time gap G2=T4−T2, or time gap G3=T4−T1.
Correspondingly, the user equipment determines T4 based on the time gap G (G1, G2 or G3) and any one of T1, T2, T3, that is, T4=T3+G1, or T4=T2+G2, or T4=T1+G3. T4 in the above embodiment can also be replaced with T5.
Or, as shown in FIG. 5, T1 is the start time of the maximum duration of the early indication signal, T2 is the start time of the actual duration of the early indication signal, T3 is the end time of the maximum duration of the early indication signal, and T3 is also the end time of the actual duration of the early indication signal, that is, the end time of the maximum duration of the early indication signal is aligned with the end time of the actual duration of the early indication signal. T4 is the start time of the PDCCH corresponding to the early indication signal, and T5 is the end time of the PDCCH corresponding to the early indication signal. Then, the time gap may be any of the three situations in FIG. 5, i.e., time gap G1=T4−T3, or time gap G2=T4−T2, or time gap G3=T4−T1; correspondingly, the user equipment determines T4 based on the time gap G (G1, G2, or G3), and any one of T1, T2, T3; that is, T4=T3+G1, or T4=T2+G2, or T4=T1+G3. T4 can also be replaced with T5.
A second embodiment is corresponding to the second manner, i.e., the scenario where the occasion of the PDCCH corresponding to the early indication signal is known.
The user equipment determines the occasion of the early indication signal based on the time gap and the occasion (i.e., the second occasion) of the PDCCH corresponding to the early indication signal. The occasion of the PDCCH corresponding to the early indication signal is configured by the network device or determined based on the UE ID. The PDCCH corresponding to the early indication signal is a PDCCH that the early indication signal instructs the user equipment to detect.
The user equipment calculates the occasion of the PDCCH corresponding to the early indication signal based on the UE ID, specifically, mapping the identifier of the user equipment (UE ID) to N downlink slots or subframes (N>0) through a certain function such as a hash function; UE ID includes IMSI, P-TMS, TMS or a short format.
As shown in FIG. 4, T1 is the start time of the actual duration of the early indication signal, and T1 is also the start time of the maximum duration of the early indication signal, that is, the start time of the maximum actual duration of the early indication signal coincides with the start time of the maximum duration of the early indication signal. T2 is the end time of the actual duration of the early indication signal. T3 is the end time of the maximum duration of the early indication signal. T4 is the start time of the PDCCH corresponding to the early indication signal. T5 is the end time of the PDCCH corresponding to the early indication signal. Then, the time gap may be any of the three situations in FIG. 4, i.e., time gap G1=T4−T3, or time gap G2=T4−T2, or time gap G3=T4−T1.
Correspondingly, the user equipment determines T1 or T2 or T3 based on the time gap G (G1, G2 or G3) and any one of T4 and T5, that is, T1=T4−G3, or T2=T4−G2, or T3=T4−G1. T4 in the above embodiment can also be replaced with T5.
Or, as shown in FIG. 5, T1 is the start time of the maximum duration of the early indication signal, T2 is the start time of the actual duration of the early indication signal, T3 is the end time of the maximum duration of the early indication signal, and T3 is also the end time of the actual duration of the early indication signal, that is, the end time of the maximum duration of the early indication signal is aligned with the end time of the actual duration of the early indication signal. T4 is the start time of the PDCCH corresponding to the early indication signal, and T5 is the end time of the PDCCH corresponding to the early indication signal.
Then, the time gap may be any of the three situations in FIG. 5, i.e., time gap G1=T4−T3, or time gap G2=T4−T2, or time gap G3=T4−T1.
Correspondingly, the user equipment determines T1, or T2, or T3 based on the time gap G (G1, G2 or G3) and T4, that is, T1=T4−G3, or T2=T4−G2, or T3=T4−G1. T4 in the above embodiment can also be replaced with T5.
In an optional embodiment, the network device may not notify the UE of the actual duration of the early indication signal of the UE. In order to reduce the complexity of detecting the early indication signal for the user equipment, the user equipment may perform blind detection for each type of actual duration of the early indication signal for only one time, and for each type of actual duration of the early indication signal, detection is performed from the first subframe of the early indication signal. For example, the network device informs the UE that there are three types of actual durations for the early indication signal in the cell, such as the numbers of repetitions for the early indication signal being 1, 10, and 100 respectively. The end subframe of actual duration of the early indication signal is subframe #9 of radio frame #9, which coincides with the end subframe of maximum duration of the early indication signal. The user equipment, in turn, performs detection of early indication signal on subframe #9 of radio frame #9; performs detection of early indication signal on 10 subframes from subframe #0 of radio frame #9 to subframe #9 of radio frame #9 (when detection is performed on the 10 subframes, the user equipment stops detecting in a case that the user equipment successfully detects the wake-up signal through N (N>1, N<10, and N is an integer) subframes thereof); and performs detection of early indication signal on 100 subframes from subframe #0 of radio frame #0 to subframe #9 of radio frame #9 (when detection is performed on the 100 subframes, the user equipment stops detecting in a case that the user equipment successfully detects the wake-up signal through N (N>1, N<100, and N is an integer) subframes thereof). The above detection sequence may be adjusted; if the early indication signal is successfully detected in a certain detection, the user equipment stops blind detection. Subframes #0 to #99 are the numbers of consecutive subframes that can transmit early indication signal. Or, the subframes for transmitting early indication signal may be inconsecutive. The above-mentioned subframe may be replaced by a slot or an OFDM symbol.
Or, the actual duration of the early indication signal is indicated by a sequence of the early indication signal. Specifically, different sequences (such as multiple different root sequences, or multiple sequences with different scrambling sequences, or multiple sequences generated by different cyclic shifts) of the early indication signal correspond to different actual durations of the early indication signal respectively.
In the method for detecting information according to some embodiments of the present disclosure, the time gap between the first occasion and the second occasion is determined by the user equipment, and the occasion of the early indication signal or the occasion of the PDCCH corresponding to the early indication signal is determined based on the time gap. In this way, the user equipment can perform detection upon arrival of the corresponding time, which further reduces blind detection complexity and detection power consumption for the user equipment. In addition, in some embodiments of the present disclosure, time gaps with different lengths can be determined based on user equipments that are of different types and with different capabilities, which reduces the unnecessary latency between the early indication signal and the corresponding PDCCH.

As shown in FIG. 8, the method for transmitting information of some embodiments of the present disclosure, operable by a network device, includes the following steps:
Step 81 includes: obtaining a time gap between a first occasion and a second occasion.
The first occasion is an occasion of an early indication signal, and the second occasion is an occasion of a physical downlink control channel (PDCCH) corresponding to the early indication signal. The early indication signal includes at least one of: a wake-up signal (WUS) or a go-to-sleep signal (GTS). The time gap is determined and reported by the user equipment, or the time gap is determined by the network device. The first occasion or the second occasion is configured by the network device for the user equipment, or the first occasion or the second occasion is determined by the user equipment based on identification information of the user equipment.
Step 82 includes: determining, based on the time gap, the occasion of transmitting the early indication signal or the occasion of transmitting the PDCCH corresponding to the early indication signal.
Step 82 may be implemented in, but not limited to, the following manners:
Corresponding to the first manner, if the first occasion has been determined, the occasion of transmitting the PDCCH corresponding to the early indication signal is determined based on the first occasion and the time gap. The first occasion is determined by the network device, or the first occasion is determined and reported by the user equipment based on the identification information (UE ID) of the user equipment.
Or, corresponding to the second manner, if the second occasion has been determined, the occasion of transmitting the early indication signal is determined based on the second occasion and the time gap. The second occasion is determined by the network device, or the first occasion is determined and reported by the user equipment based on the identification information (UE ID) of the user equipment.
In an embodiment, after step 82, the method further includes: transmitting the early indication signal at the determined occasion of transmitting the early indication signal, or transmitting the PDCCH at the determined occasion of transmitting the PDCCH corresponding to the early indication signal.
Optionally, the step of determining the occasion of transmitting the early indication signal includes: determining a start time or an end time of a maximum duration of transmitting the early indication signal, or determining a start time or an end time of an actual duration of transmitting the early indication signal. The number of the actual duration is at least one, and the start time of each of the at least one actual duration is the same as the start time of the maximum duration of the early indication signal; or, the number of the actual duration is at least one, and the end time of each of the at least one actual duration is the same as the end time of the maximum duration.
In some optional embodiments, the first occasion is a start time or an end time of a maximum duration of the early indication signal, that is, the occasion of the early indication signal is the start time or the end time of the maximum duration of the early indication signal, where the maximum duration of the early indication signal is explained as follows. In order to improve the transmission reliability of the early indication signal, different numbers of repetitions of the early indication signal may be set for different user equipments or cells; the different numbers of repetitions are realized based on repeatedly transmitting time domain transmission unit(s) in the time, and the time domain transmission unit(s) may be a frame, a subframe (subframe), a slot (slot) or a time domain symbol (an OFDM symbol). For the specific configuration manner, reference can be made to that of the embodiments of the user equipment side, which is not described herein
Or, the first occasion is a start time or an end time of an actual duration of the early indication signal, that is, the occasion of the early indication signal is the start time or the end time of the actual duration of the early indication signal. The duration corresponding to the actual number of repetitions of the early indication signal is the actual duration (actual duration) of the early indication signal.
The actual duration has only one possible position (the only position) within the maximum duration, that is, there is a first duration between the start time of the actual duration of the early indication signal and the start time of the longest duration of the early indication signal, where the first duration is greater than or equal to 0 time domain transmission unit. When the first duration is 0 time domain transmission unit, the start time of the actual duration of the early indication signal is the same as the start time of the longest duration (i.e., coinciding). Or, there is a second duration between the end time of the actual duration of the early indication signal and the end time of the longest duration of the early indication signal, where the second duration is greater than or equal to 0 time domain transmission unit. When the second duration is 0 time domain transmission unit, the end time of the actual duration of the early indication signal is the same as the end time of the longest duration (i.e., coinciding).
Optionally, the second occasion is a start time or an end time of time domain transmission unit(s) where the PDCCH is located, where the time domain transmission unit(s) includes any one of: a time domain symbol, a subframe, or a slot. In other words, the occasion of the PDCCH is the start time or the end time of the slot, subframe, or time domain symbol where the PDCCH is located.
The duration of the time gap is related to at least one of the following:
A type of a receiver that receives the early indication signal. The type of the receiver includes a main receiver and a non-main receiver (or referred to as other receiver, dedicated receiver). That is, the corresponding duration of the time gap for a case where the user equipment uses the independent non-main receiver to receive the early indication signal is different from the corresponding duration of the time gap for a case where the user equipment uses the main receiver receive the early indication signal.
A preset behavior of the user equipment. The preset behavior includes: the user equipment performing downlink synchronization only based on the early indication signal, or, the user equipment performing downlink synchronization based on the early indication signal and a synchronous signal block, or, the user equipment performing downlink synchronization only based on a synchronous signal block. If the user equipment only uses WUS to perform downlink synchronization, and if the network device sends DTX for several consecutive paging cycles, then in the subsequent the time for downlink synchronization may be relatively long when the user equipment receives non-DTX WUS, resulting in increased time gap between WUS and PDCCH corresponding to the WUS; if the user equipment periodically performs downlink synchronization based on SSB, the user equipment may flexibly set the size of the period to maintain good downlink synchronization, and in the subsequent the time for downlink synchronization may be relatively short when the user equipment receives non-DTX WUS, resulting in increased time gap between WUS and PDCCH corresponding to the WUS. Therefore, when the behaviors of the user equipment are different, the values of the time gaps reported by the user equipment are also different.
A frequency domain transmission resource of the early indication signal, and a frequency domain transmission resource of the PDCCH corresponding to the early indication signal. In an embodiment, the time gap corresponding to a case where the center frequency of the frequency domain resource of the user equipment for receiving WUS or GTS is different from the center frequency of the frequency domain resource of the user equipment for receiving PDCCH, is longer than, the time gap corresponding to a case where the center frequency of the frequency domain resource of the user equipment for receiving WUS or GTS is the same as the center frequency of the frequency domain resource of the user equipment for receiving PDCCH; the frequency domain resource may be a bandwidth part (BWP), a bandwidth or a channel.
The time gap is determined and reported by the user equipment, or the time gap is determined by the network device, or the time gap is predefined by the protocol. Specifically, the time gap includes at least one of: a first time gap determined by the user equipment, or a second time gap configured by the network device for the user equipment.
When the time gap includes the second time gap, corresponding to the second scenario and the third scenario, the network device may configure the second time gap to the user equipment in the following manner: sending the time gap to the user equipment through preset signaling. The preset signaling includes at least one of: broadcast signaling, radio resource control (RRC) signaling, media access control (MAC) control element (CE), or a PDCCH.

In the method for transmitting information according to some embodiments of the present disclosure, the time gap between the first occasion and the second occasion is determined by the network device, and the occasion of the early indication signal or the occasion of the PDCCH corresponding to the early indication signal is determined based on the time gap. In this way, the user equipment can determine the corresponding time based on the time gap and perform detection at the corresponding time, which further reduces blind detection complexity and detection power consumption for the user equipment. In addition, in some embodiments of the present disclosure, time gaps with different lengths can be determined based on user equipments that are of different types and with different capabilities, which reduces the unnecessary latency between the early indication signal and the corresponding PDCCH.
