Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a processing method, a terminal device, a network device and a storage medium. Background Art

[0002] In the fifth generation (5G) cellular mobile communication system, the process of user equipment (UE) receiving paging messages includes: detecting the physical downlink control channel (PDCCH) in the search space corresponding to the paging occasion (PO), and then parsing the downlink control information (DCI) carrying the paging scheduling information. If the DCI is successfully parsed, the physical downlink shared channel (PDSCH) resources are used to receive and demodulate the paging message based on the scheduling of the paging scheduling information. For UEs working with discontinuous receivers (DRX), if the identity document (ID) of the received paging message is the UE's own, a connection is initiated, otherwise it continues to sleep; if the DCI is not parsed, it means that there is no paging message in the wake-up (DRX_on) cycle.

[0003] During the process of conceiving and implementing this application, the inventors found that there are at least the following problems: when receiving paging messages, the UE needs to detect the search space corresponding to each PO, the UE needs to wake up frequently, or the UE time and frequency synchronization takes a long time, and the UE wake-up time is long, causing the UE to consume more power.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Summary of the invention

[0005] In response to the above technical problems, the present application provides a processing method, a terminal device, a network device and a storage medium, which aim to solve the technical problems of high power consumption and low energy saving when the UE receives a paging message.

Alternatively, the wireless communication system may be a next generation system of the 5G system. Optionally, the access network in the 5G system may be referred to as NG-RAN (New Generation-Radio Access Network).

[0193] Optionally, the base station may be an evolved base station (eNB) adopted in a 4G system. Alternatively, the base station may also be a base station (gNB) adopting a centralized distributed architecture in a 5G system. When the base station adopts a centralized distributed architecture, it generally includes a centralized unit (CU) and at least two distributed units (DU).

[0198] The execution entities involved in the embodiments disclosed in this application include but are not limited to: UEs such as mobile phone terminals supporting cellular mobile communications, and / or network devices such as base stations.

[0199] To assist in understanding the technical solutions of the various embodiments of the present application, in some or all of the embodiments, the terminal device may be a UE, and the network device may be a base station.

[0200] During the process of receiving and processing the paging message of the UE, the inventor of the present application found the following problems or defects:

[0201] (1) A UE in the RRC (Radio Resource Control) idle / inactive state needs to monitor the PO (Paging Occasion) in each paging cycle to confirm whether it needs to decode the paging PDCCH (Physical Downlink Control Channel) / PDSCH (Physical Downlink Shared Channel).

[0202] When the UE is not paged, this ineffective PO monitoring and paging PDCCH, SSB (Synchronization Signal Block) processing will cause a lot of power consumption. To address this defect, it is determined to use the PEI (Paging Early Indication) indication method to decide in advance whether PO monitoring is needed. When there is no paging message, unnecessary SSB synchronization processing and paging PDCCH decoding can be avoided, thus achieving the purpose of reducing power consumption.

[0203] In order to further reduce power consumption, the present application proposes a technical solution in which a PEI can be used to indicate whether at least one PO needs to be monitored, for example, a DCI (Downlink Control Information)-based PEI can be used to indicate whether at least one PO needs to be monitored.

[0204] (2) In order to enable UEs in RRC_IDLE / RRC_INACTIVE state to better implement PO demodulation, UEs supporting RRC_IDLE / RRC_INACTIVE state are configured with TRS (Tracking Reference Signal) / CSI-RS (Channel State Information-Reference Signal). However, there is no consensus on whether the TRS / CSI-RS acquisition indication should be carried through PEI, paging DCI or SIB1 (System Information Block 1), and if the TRS / CSI-RS acquisition indication is carried through PEI, one PEI carries the TRS / CSI-RS acquisition indication corresponding to at least one PO, and there is no established solution on how to indicate it.

[0205] The technical solution of the embodiment of the present application is mainly used to solve the following technical problems:

[0206] (1) If a PEI is used to indicate whether a PO is monitored, how does a PEI indicate the monitoring status of at least one PO in a DRX cycle, and how is the PEI indication designed to minimize the number of times the UE is woken up, thereby reducing energy consumption; and / or,

[0207] (2) If the TRS / CSI-RS acquisition status is indicated by PEI, how can a PEI implement at least one TRS / CSI-RS acquisition indication so that the UE can confirm in advance whether TRS can be used for assisted time and frequency synchronization, thereby reducing the number of SSBs used by the UE for time and frequency synchronization, thereby reducing system energy consumption.

[0208] The technical solution of the embodiments of the present application can solve the above-mentioned problem (1) and / or problem (2).

[0209] Optionally, to assist in understanding the various embodiments of the processing method of the present application, the relevant background of the embodiments of the present application is briefly introduced:

[0210] Regarding NR paging technology, according to protocol TS 38.300 RRC_INACTIVE

[0211] The purpose of paging is to send paging information (Paging message) to the terminal, notify system message changes and emergency messages (ETWS / CMAS indications). The terminal device only listens to the CN (Core Network) initiated (CN-initiated) paging information in the RRC_IDLE state (discontinuous reception state). The terminal device listens to the CN initiated (CN-initiated) paging information and the RAN (Radio Access Network) initiated (RAN-initiated) paging information in the RRC_IDLE state or RRC_INACTIVE state (sleeping state). The terminal device does not need to monitor the paging channel at all times in the RRC_IDLE state or RRC_INACTIVE state, but monitors a PO with the shortest DRX cycle configured by the network. Therefore, a paging cycle can also be called Paging DRX. The network-configured DRX includes the following three types:

[0212] 1. Paging initiated by the core network.

[0213] 2. Default Cycle: configured by system message.

[0214] 3. UE specific cycle: configured by NAS (Non-Access Stratum) signaling.

[0215] For paging initiated by the wireless network, the terminal-specific cycle (UE-specific cycle): configured by RRC (Radio Resource Control) signaling, the terminal device selects the shortest cycle in the configured cycle as the listening cycle according to the current RRC state. That is, the terminal device needs to select the shortest cycle from "Default Cycle" or "UE Specific Cycle" in RRC_IDLE, and when the terminal device is in RRC_INACTIVE state, it selects the shortest one from the above three cycles.

[0216] Regardless of whether the paging is initiated by the core network or the wireless network, the terminal device confirms the paging timing based on the same "UE_ID" (identity document (ID) of the paging message).

[0217] Paging opportunity calculation method: i_s = floor (UE_ID / N) mod Ns.

[0218] The paging frame is determined by: (SFN+PF_offset) mod T = (TdivN)*(UE_IDmodN).

[0219] The terminal device monitors and detects whether there is a P-RNTI-scrambled PDCCH at the corresponding paging opportunity to confirm whether it carries a paging message. If so, the terminal device further parses (decodes) the paging message sent on the PDSCH.

[0220] In order to reduce power consumption of UE during the process of receiving paging message, the present application provides a processing method, which is applied to terminal equipment (ie UE). In one embodiment, referring to Figure 3 , the processing method comprises the following steps:

[0221] S10, receiving PEI;

[0222] S20, indicating a listening state of at least one PO of at least one PF and / or an acquisition state of a TRS according to the PEI;

[0223] S30, determining whether to monitor a paging message according to the monitoring status, and / or determining whether to perform time-frequency synchronization through the TRS according to the acquisition status of the TRS.

[0224] When the terminal device receives a paging message, the terminal device obtains the PEI of the corresponding PO in each PF at a fixed position before each PO in the first PF of each group, and the PEI includes at least one indication information.

[0225] In one implementation, the indication information can be used to indicate the listening status of the PO in at least one PF (Paging Frame) at the current moment and after the current moment, that is, the indication information can indicate in advance whether the PO in at least one PF needs to be listened to. After receiving the PEI, the terminal device can know in advance the listening status of the PO in at least one subsequent PF according to the indication information. The terminal device can continue to remain dormant during the subsequent paging period when the listening status is not listening, and only wake up at the subsequent paging period when listening is required. Therefore, the terminal device can be specifically awakened according to the indication information in the PEI and the listening status of the PO, thereby avoiding frequent waking up for search space detection at each paging period, thereby achieving power consumption saving of the terminal device.

[0226] In another implementation, the indication information can also be used to indicate the acquisition status of the TRS (Tracking Reference Signal) corresponding to the PO in at least one PF at the current moment and after the current moment, that is, the indication information can indicate in advance whether the TRS of the PO in at least one PF is available. After receiving the PEI, the terminal device knows in advance the acquisition status of the TRS corresponding to the PO in at least one subsequent PF according to the indication information. When the subsequent TRS is available and PO monitoring is required, the TRS can be used to perform auxiliary time-frequency synchronization, quickly achieve downlink synchronization, and complete PO demodulation. In this way, the number of SSBs used by the terminal device for downlink synchronization can be reduced, the synchronization time of the terminal device can be shortened, and the power consumption of the terminal device can be reduced.

[0227] Optionally, if the terminal device has TRS for auxiliary time and frequency synchronization, it may only need to parse one SSB, but if it does not have TRS for auxiliary time and frequency synchronization, it may need to parse three SSBs, thereby reducing the number of SSBs used for downlink synchronization, shortening the downlink synchronization duration, and thereby reducing the time it takes to wake up the terminal device.

[0228] In another implementation, the indication information may indicate the monitoring status of the PO in at least one PF before and after the current moment and the acquisition status of the corresponding TRS, that is, the indication information may indicate in advance whether the PO in at least one PF needs to be monitored and whether the corresponding TRS is available. After receiving the PEI, the terminal device may know in advance the monitoring status of the PO in at least one subsequent PF according to the indication information. The terminal device may continue to remain dormant during subsequent paging occasions that do not require monitoring, and only wake up during subsequent paging occasions that require monitoring, thereby avoiding frequent wake-ups and search space detection at each paging occasion, increasing the sleep time of the paging occasion, and reducing the power consumption of the terminal device. The indication information may also indicate in advance whether the TRS corresponding to the PO in at least one PF is available, and is particularly used to indicate in advance whether the TRS corresponding to the PO that at least one PF needs to monitor is available. At the paging occasion when monitoring is required and TRS is available, the terminal device may choose to perform auxiliary time-frequency synchronization through TRS to shorten the duration of PO demodulation by the terminal device, thereby saving power consumption of the terminal device.

[0229] In this embodiment, PEI is received, and the listening status of at least one PO of at least one PF and / or the acquisition status of TRS are determined through the indication information in PEI, and then whether to listen to the paging message is determined according to the listening status, and / or, whether to perform time and frequency synchronization through TRS is determined according to the acquisition status of TRS. In the process of the terminal device receiving the paging message, the number of times the terminal device wakes up is reduced and / or the wake-up time of the terminal device is reduced, thereby reducing the power consumption of the terminal device.

[0230] To assist in understanding the technical content related to the acquisition status of TRS, the following briefly describes the related research on TRS.

[0231] In the research process of paging processing, TRS / CSI-RS can be used for UE to obtain channel status, beam management, mobility management and rate matching.

[0232] There will be a small deviation in the frequency of the physical crystal oscillator of the base station and the UE, and they cannot be completely consistent. This causes the phase deviation of the RF carrier signal received by the UE. In the demodulation symbol constellation diagram of the received subcarrier, it is manifested as a phase rotation, that is, the received modulation symbol deviates from a certain phase angle. This is caused by the accumulation of frequency deviation in time. At this time, TRS is needed to track the rotation phase of other data signals. TRS is a multi-periodic TRS / CSI-RS, or more precisely, a 4-1 port, 3 TRS / CSI-RS density, NZP-TRS / CSI-RS located in two consecutive time slots. The minimum time interval between two TRSs in a time slot is 4 OFDM symbols, and the domain is separated by 4 subcarriers. The frequency and time errors can be estimated based on TRS. The received data compensates for these errors and can rotate back to the modulation coordinate position originally sent.

[0233] The shared TRS / CSI-RS may be a TRS / CSI-RS shared by an idle UE and / or an inactive UE and a connected UE. An idle UE and / or an inactive UE and a connected UE may monitor the TRS / CSI-RS at the shared TRS / CSI-RS timing. The shared TRS / CSI-RS may also be used for the UE to perform downlink synchronization with the base station. After completing the downlink synchronization, the UE may receive the downlink signal of the base station.

[0234] The UE in the RRC_IDLE state or the RRC_INACTIVE state supports the TRS / CSI-RS function to better implement the synchronization function and thus better implement PO demodulation.

[0235] This application supports the realization of TRS / CSI-RS acquisition indication through PEI (ie, TRS-related indication information in PEI), and supports one PEI to support TRS / CSI-RS acquisition indication corresponding to at least one PO. The specific implementation ideas are as follows:

[0236] If the TRS / CSI-RS acquisition indication corresponding to each PO is different, one PEI indicates the acquisition status of the TRS / CSI-RS at the corresponding position of at least one PF, which saves more signal resources than placing a PEI indicating the acquisition status of TRS / CSI-RS in front of each PO of each PF; at the same time, TRS / CSI-RS can also be used to assist downlink synchronization and shorten the PO demodulation time. The PEI jump indication TRS acquisition status is basically the same as the PEI jump indication PO monitoring status indication method.

[0237] Based on the above embodiments, the inventors found that: the indication information of a PEI can indicate at least one continuous PO in the PF, but this method of continuously indicating at least one PO occupies more available resources of the PEI. If the PEI is a DCI-based PEI (carrying paging indication by DCI bit mapping), then the PEI continuously indicates at least one PO and wastes the occupied resources of the DCI bit. For example, refer to Figure 4 If a PF has 12 POs, 144 bits are needed to indicate 12 PFs continuously, resulting in a waste of bits; if the PEI is an SSS-based PEI (PEI is carried by mapping the SSS (Secondary Synchronization Signa1) reference signal) or a TRS-based PEI, based on the SSS sequence or the TRS sequence, 144 sequences are needed to indicate continuous POs, resulting in a waste of sequences.

[0238] Based on this problem, the present application further proposes another embodiment, in which the indication information of a PEI jumps to indicate the monitoring status and / or TRS acquisition status of at least one PO of each PF preset mapping position in at least one PF, and the preset mapping position may be the same position in each PF (that is, the sorting position of the PO in the PF is the same), that is, the indication information is used to indicate the monitoring status of the PO at the same position of at least one PF. In an optional implementation manner, it may be at least one of the following:

[0239] The indication information jump indication of the first PEI of the first PF: the first PO of the first PF, the first PO of the second PF, the first PO of the third PF;

[0240] The indication information jump indication of the second PEI of the first PF: the second PO of the first PF, the second PO of the second PF, the second PO of the third PF;

[0241] The indication information of the third PEI of the first PF jumps to indicate: the third PO of the first PF, the third PO of the second PF, and the third PO of the third PF.

[0242] The above is only a detailed explanation of the same position, which may include but is not limited to three PFs, and also includes but is not limited to three POs for each PF.

[0243] Optionally, the preset mapping position may also be a non-identical position in each PF, as long as the PEI completes the jump indication of all POs in at least one PF. For example, the indication information of the PEI jumps to indicate the POs at positions where the sorting positions in at least one PF are incremented one by one until all POs in the PF are traversed, that is, the indication information is used to indicate the monitoring status of POs at different positions of at least one PF. In an optional implementation, it may be at least one of the following:

[0244] The indication information jump indication of the first PEI of the first PF: the first PO of the first PF, the second PO of the second PF, and the third PO of the third PF;

[0245] The indication information jump indication of the second PEI of the first PF: the second PO of the first PF, the third PO of the second PF, and the first PO of the third PF;

[0246] The indication information of the third PEI of the first PF jumps to indicate: the third PO of the first PF, the first PO of the second PF, and the second PO of the third PF.

[0247] The above is only a detailed explanation of non-identical positions, which may include but are not limited to three PFs, and also include but are not limited to three POs per PF.

[0248] In this embodiment, the indication information of a PEI jumps to indicate at least one PO of the preset mapping position of each PF in at least one PF, saving the available signal resources of the PEI. For example, taking DCI-based PEI as an example, there are 2 PFs, each PF has 4 POs, and 8 DCI bits are required to continuously indicate 2 PFs through one PEI. However, if the first PO of the 2 PFs is indicated by one PEI, then the 2 PFs only need 2 DCI bits. Similarly, PEI jumps to indicate PO of multiple PFs with SSS-based PEI or TRS-based PEI, which can also save sequence resources. In other words, by jumping to indicate the PO of the preset mapping position of each PF in at least one PF through the indication information of one PEI, DCI bits or reference signal sequences can be saved, that is, PEI jumps to indicate PO, which can save signal resources used for indication.

[0249] To help understand the technical solution, a specific PEI scenario is used as an example:

[0250] In the scenario where a PF has only one PEI:

[0251] Reference Figure 5 , SearcheSpaceId=0,Ns=1,N=T / 16,T=32,then N=32 / 16=2,that is, when DRXCycle=32 radio frames, there are N=2 PFs in one DRX Cycle, and each PF has Ns=1 PO. The PEI jump before the first PO of PF0 indicates the monitoring status of a single PO of PF0 and PF1.

[0252] Reference Fig. 9 , SearcheSpaceId=0,Ns=1,N=T / 16,T=32,then N=32 / 16=2, that is, when DRXCycle=32 radio frames, there are N=2 PFs in a DRX Cycle, and each PF has Ns=1 PO. The PEI jump before the first PO of PF0 indicates whether the TRS corresponding to the single PO of PF0 and PF1 is available.

[0253] Optionally, the PEI jump indicates the monitoring status of at least one PO of each PF preset mapping position in at least one PF and the acquisition status of the TRS, that is, Figure 5 and Fig. 9 PEI indicates both the listening state of PO and the acquisition state of TRS. Fig.14 , SearcheSpaceId=0, Ns=1, N=T / 16, T=32, then N=32 / 16=2, that is, when DRXCycle=32 wireless frames, there are N=2 PFs in a DRX Cycle, each PF has Ns=1 PO, and the PEI before the first PO of PF0 jumps to indicate the monitoring status of the single PO of PF0 and PF1, and then jumps to indicate whether the TRS corresponding to the single PO of PF0 and PF1 is available.

[0254] Optionally, the monitoring state may include at least one of the following: monitoring, no need for monitoring, or partial monitoring and partial no need for monitoring, and / or the acquisition state may include at least one of the following: available, unavailable, or partially available and partially unavailable.

[0255] In the scenario where a PF includes multiple PEIs:

[0256] Reference Figure 6, SearcheSpaceId=1,Ns=4,N=T / 8;T=32;then N=32 / 8=4, that is, when DRX Cycle=32 radio frames, there are N=4 PFs in one DRX Cycle, and each PF has Ns=4 POs. The indication information of PEI before PO0 of PF0 jumps to indicate PO0 of PF0 to PF3, the indication information of PEI before PO1 of PF0 jumps to indicate PO1 of PF0 to PF3, the indication information of PEI before PO2 of PF0 jumps to indicate PO2 of PF0 to PF3, the indication information of PEI before PO3 of PF0 jumps to indicate PO3 of PF0 to PF3, PF0 to PF3 are in the same DRX cycle, and PF0 to PF3 are also in the same group. Optionally, regarding PFs of multiple DRX cycles belonging to one or more groups, the jump indication logic of the indication information of PEI is basically the same, which will not be described in detail here.

[0257] Optionally, the inventors have found that if a PEI indicates multiple POs continuously, it may only indicate part of the PFs in a DRX cycle. In a scenario where the paging rate is very low, the terminal device only knows the monitoring status of at least one PO of part of the PFs in a DRX cycle and / or whether time-frequency synchronization is performed through TRS. It can only avoid unnecessary wake-up times and / or unnecessary wake-up time for at least one PO of a small part of the PFs in a DRX cycle, and cannot achieve the purpose of better power consumption reduction. In one embodiment, to solve this problem, before step S10, the processing method further includes:

[0258] S00, determining a PF of at least one packet in at least one DRX cycle.

[0259] Before receiving PEI, the terminal device may first determine the grouping status of PF. A PEI may indicate the monitoring status of at least one PO of multiple PFs in a group and / or the acquisition status of TRS. For example, a PEI indicates the PO of the preset mapping position of multiple PFs in a group. It may be that PFs within a DRX cycle form one group, or PFs within a DRX cycle form multiple groups, or PFs within multiple DRX cycles form one group.

[0260] Since the indication information of a PEI jumps to indicate non-continuous POs of multiple PFs in a group, each PEI is only used to indicate the listening status of a PO of each PF in a group and / or the acquisition status of TRS, so each PEI can indicate the PF of the entire or most of the DRX cycle. In this way, when the terminal device is in a low paging rate scenario, it is only necessary to parse the Ns POs in the first PF in the group (each PF corresponds to Ns POs), so as to know the listening status and / or the acquisition status of TRS of Ns POs in the PF in a DRX cycle or multiple DRX cycles, thereby avoiding the terminal device from being awakened at a paging time when no monitoring is required, so that the terminal device can be in a dormant state for a longer time, thereby reducing power consumption; and / or the terminal device obtains the acquisition status of TRS corresponding to the PO according to the PEI, and uses TRS for auxiliary time and frequency synchronization, thereby shortening the wake-up time and saving power consumption.

[0261] To help understand the technical solution, we will take a specific PEI scenario as an example:

[0262] In the scenario where a PF includes multiple PEIs and a DRX cycle includes multiple groups, refer to Figure 7 , SearcheSpaceId=0, Ns=2, N=T / 4, T=256, then N=256 / 4=64, that is, when DRX Cycle=256 wireless frames, there are N=64 PFs in one DRX cycle, and each PF has Ns=2 POs. Then the PO in the entire DRX cycle is divided into two parts (i.e., group 1 and group 2) for PEI indication.

[0263] It should be noted that in Figure 7 In the example, the indication information of PEI can indicate the TRS of each PF in group 1 and group 2. Fig.10 For example, see Fig.10 , SearcheSpaceId=0, Ns=2, N=T / 4, T=256, then N=256 / 4=64, that is, when DRXCycle=256 wireless frames, there are N=64 PFs in a DRX Cycle, and each PF has Ns=2 POs. Then the PO in the entire DRXCycle is divided into two parts (i.e., group 1 and group 2) for PEI indication.

[0264] against Fig.10 In one embodiment, if PEI is DCI-based and the number of bits used for PEI indication is 48, then a PEI can indicate L=32 PFs. The embodiment design diagram is only used to indicate the scheduling process, and does not indicate that the scheduled PFs are scheduled in parallel, that is, PF0, PF1, ......., PF63 are arranged in chronological order. Fig.10The grouping method and PEI jump indication TRS indication method also apply to Figure 7 , Figure 8a and Figure 8b , Figure 7 , Figure 8a and Figure 8b PEI can synchronously indicate the acquisition status of TRS corresponding to PO. Fig.10 The applicability of grouping and indication methods can be found in Fig.10 Add PEI jump indication to indicate the monitoring status of at least one PO of each PF group, please refer to Fig.15 , the PEI jump indicates the monitoring status of the PO and the acquisition status of the TRS at the corresponding position of each PF in each group.

[0265] For example, refer to Figure 8a and Figure 8b , SearcheSpaceId=1, Ns=4, N=T / 2, T=256, then N=256 / 2=128, that is, when DRX cycle=256 radio frames, there are N=128 PFs in a DRX Cycle, and each PF has Ns=4 POs. Then the PO in the entire DRX Cycle is divided into four parts (group 1, group 2, group 3 and group 4) for PEI indication.

[0266] Optionally, the PEI is located before the corresponding PO in the first PF in the same group, and the at least one PF indicated by the indication information exists in the at least one group. When the terminal device is in the RRC idle or RRC INACTIVE state, during the process of the terminal device monitoring the paging message,

[0267] (1) If there is only one group in a DRX cycle, a PEI is placed before each of the Ns PO monitoring of the first PF in a DRX cycle. The indication information of this PEI indicates whether the PO at the corresponding position of each PF in the entire DRX cycle needs to be monitored and / or whether to perform auxiliary time and frequency synchronization through TRS. If monitoring is not required, the terminal device directly skips the PO that does not need to be monitored and remains dormant. It is only awakened to perform PDCCH monitoring when the paging time that needs to be monitored is required, and / or when the PO needs to be monitored and the TRS indicated by the PEI is available, it performs auxiliary time and frequency synchronization through TRS.

[0268] (2) If multiple DRX cycles belong to the same group, a PEI is placed before each of the Ns PO monitorings of the first PF of the first DRX cycle in timing, and the indication information of this PEI indicates whether the PO at the corresponding position of each PF of the multiple DRX cycles needs to be monitored and / or whether to perform auxiliary time-frequency synchronization through TRS. If monitoring is not required, the terminal device directly skips the PO that does not need to be monitored and remains dormant. It is only awakened to perform PDCCH monitoring when the paging opportunity that needs to be monitored is required, and / or when the PO needs to be monitored and the TRS indicated by the PEI is available, it performs auxiliary time-frequency synchronization through TRS.

[0269] (3) If a DRX cycle contains multiple groups, a PEI is placed before the Ns PO monitoring of the first PF of each group. The indication information of this PEI indicates whether the PO at the corresponding position of each PF of each group needs to be monitored and / or whether to perform auxiliary time and frequency synchronization through TRS. If monitoring is not required, the terminal device directly skips the PO that does not need to be monitored and remains dormant. It is only awakened at the PO position that needs to be monitored to monitor PDCCH, and / or when the PO needs to be monitored and the TRS indicated by the PEI is available, it performs auxiliary time and frequency synchronization through TRS.

[0270] In yet another embodiment, the step S00 includes: determining a PF of at least one packet in at least one DRX cycle according to the first number and / or the second number.

[0271] The first number is the number of PFs included in the DRX cycle, and the second number is the number of identifiers carrying the indication information of the PEI. Based on the first number and / or the second number, determine which paging frames of the DRX cycle the PF of at least one packet in at least one DRX cycle is, such as determining the number L of PFs of a packet based on the first number and the second number.

[0272] For ease of understanding, assume that the first number is N, the second number is G, and the total number of radio frames in a DRX cycle is T. Based on the protocol relationship in Table 2, it can be seen that N, the number of PFs in a group is L, and L=2 x <=G. For the scenario where there are more than L PFs in a DRX cycle (i.e., N>L), a classification indication can be made for each L PF to form a group. The advantage of indicating only the L PFs of the entire DRX cycle is that DCI bits or reference signal sequences are saved, so that at most only L DCI bits or reference signal sequences are needed to indicate the entire DRX cycle. The value of L depends on the number of DCI bits or reference signal sequences ultimately used to carry PEI (i.e., the second number G). For example, based on L=2 x<=G, DCI-based PEI has 48 bits (ie, G=48), then L is 32; DCI-based PEI has 12 bits (ie, G=12), then L is 8.

[0273] against Figure 7 The embodiment is given assuming that the number of DCI-based PEI bits is 48 and one PEI indicates L=32 PFs. The embodiment design diagram is only used to show the scheduling process, and does not mean that the scheduled PFs are scheduled in parallel, that is, PF0, PF1, ......., PF63 are arranged in chronological order.

[0274] Optionally, the meanings of Paging-related parameters are summarized according to 38.304 and 38.331 protocols, as shown in Table 1. According to possible values ​​of high-level signaling, the number of PFs that may exist in a DRX cycle is summarized in Table 2.

[0275] As can be seen from Table 2, there may be too many PFs in a DRX cycle. In order to save DCI bits or reference signal sequences, classification is made according to the different numbers of PFs in the DRX cycle. The purpose is to use as many bits or reference signal sequences as possible to indicate the PF in the DRX cycle, so as to ensure that the terminal equipment can be in sleep state for a longer time under low paging rate, so as to reduce power consumption.

[0294] For step S30, further detailed description is as follows:

[0305] In one implementable embodiment, the indication information of PEI can instruct the terminal device to: listen to at least one PO of different PFs in at least one group and not perform auxiliary time and frequency synchronization based on at least one TRS of different PFs in at least one group, and not listen to at least one PO of different PFs in at least one group and perform auxiliary time and frequency synchronization based on at least one TRS of different PFs in at least one group, that is, the listening status of multiple POs of different PFs in at least one group is partially listened and partially does not need to be listened, the acquisition status of multiple TRSs of different PFs in at least one group is partially available and partially unavailable, the terminal device listens to at least one PO of different PFs in at least one group and indicates that at least one TRS of different PFs in at least one group is unavailable, and does not listen to at least one PO of different PFs in at least one group and indicates that at least one TRS of different PFs in at least one group is available.

[0306] In one implementable embodiment, the indication information of PEI can instruct the terminal device to: listen to at least one PO of different PFs in at least one group and do not perform auxiliary time and frequency synchronization based on at least one TRS of different PFs in at least one group, and do not listen to at least one PO of different PFs in at least one group and do not perform auxiliary time and frequency synchronization based on at least one TRS of different PFs in at least one group, that is, the listening status of multiple POs of different PFs in at least one group is partial listening and partial no need to listen, the acquisition status of at least one TRS of different PFs in at least one group is unavailable, the terminal device listens to at least one PO of different PFs in at least one group and indicates that at least one TRS of different PFs in at least one group is unavailable, and does not listen to at least one PO of different PFs in at least one group and indicates that at least one TRS of different PFs in at least one group is unavailable.

[0307] In one implementable embodiment, the indication information of PEI can instruct the terminal device: not to monitor at least one PO of different PFs in at least one group and to perform auxiliary time-frequency synchronization based on at least one TRS of different PFs in at least one group, and not to monitor at least one PO of different PFs in at least one group and to perform auxiliary time-frequency synchronization based on at least one TRS of different PFs in at least one group, that is, the monitoring status of at least one PO of different PFs in at least one group is that no monitoring is required, and the acquisition status of multiple TRS of different PFs in at least one group is that some are available and some are not available, the terminal device does not monitor at least one PO of different PFs in at least one group and indicates that at least one TRS of different PFs in at least one group is available, and does not monitor at least one PO of different PFs in at least one group and indicates that at least one TRS of different PFs in at least one group is not available.

PEI can be located before each PO in the first PF in the same group, and provides an implementation method for PEI to jump to indicate at least one PO of different PFs, saving the number of identifiers carrying PEI (such as DCI bit or reference signal sequence), ensuring that the terminal device can be in a sleep state for a longer time under a low paging rate and / or can perform PO demodulation in a shorter time to reduce power consumption.

[0309] Optionally, the step S20 includes:

[0310] S21: Determine, according to the PEI, the monitoring state of at least one PO of at least one PF in the same or different DRX cycles and / or the acquisition state of the TRS.

[0311] Optionally, step S21 includes at least one of the following:

[0312] If the PF within the configured DRX cycle is configured as a single group, the indication information in the PEI before each PO in the first PF of the single group is parsed to determine the listening status of the PO at the corresponding position of each PF of the single group and / or the acquisition status of the TRS; optionally, the listening status includes listening, no need for listening, or partial listening and partial no need for listening, and the acquisition status can be available, unavailable, or partially available and partially unavailable.

[0313] If the PF within the configured DRX cycle is configured as multiple groups, the indication information in the PEI before each PO in the first PF of each group is parsed to determine the listening status and / or TRS acquisition status of the PO at the corresponding position of each PF of each group.

[0314] Optionally, step S21 includes at least one of the following:

[0315] If the PF in the configured DRX cycle is configured as a single group, the indication information in the PEI before each PO in the first PF of the single group is parsed to determine the monitoring status and / or TRS acquisition status of the POs at the corresponding positions of the non-continuous multiple PFs selected by the predetermined rule of the single group;

[0316] If the PF within the configured DRX cycle is configured as multiple groups, the indication information in the PEI before each PO in the first PF of each group is parsed to determine the listening status and / or TRS acquisition status of the PO at the corresponding positions of multiple non-continuous PFs selected by the predetermined rules of each group.

[0317] Optionally, the predetermined rule may be to determine multiple non-continuous PFs by selecting odd or even numbers of PF sequence numbers in the group, selecting an arithmetic progression, etc., to distinguish each continuous PF in the group. The predetermined rule selects multiple non-continuous PFs that are applicable to the situations of a single group and multiple groups.

[0318] In the preset rule one feasible method, the preset rule is an odd-even selection method, that is, a PF with an odd or even number is selected in a group, the PEI before each PO before the first PF in this group is parsed, and the listening status and / or TRS acquisition status of the POs at the corresponding positions of multiple non-continuous PFs with odd or even numbers are determined.

[0319] In an optional embodiment, the preset rule is to select a plurality of non-continuous PFs with odd sequence numbers, referring to Fig.16 , a group includes 6 PFs, each PF has 2 POs, and the PFs in the group are PF0, PF1, PF2, PF3, PF4, and PF5. The PEI jumps before PO0 and PO1 in the first PF0 of this group indicate the monitoring status of the POs at the corresponding positions in PF1, PF3, and PF5 and the acquisition status of TRS. It should be noted that in this optional embodiment, only a detailed explanation of selecting non-continuous multiple PFs according to the preset rules is provided, which may include but is not limited to 6 PFs, and also includes but is not limited to 2 POs for each PF.

[0320] Optionally, the preset rule may be to select multiple non-contiguous PFs with even serial numbers, for example, a group includes 12 PFs, and the PEI jump of the first PF in the group indicates the listening status and / or TRS acquisition status of the PO at the corresponding positions of PF2, PF4, PF6, PF8, PF10 and PF12.

[0321] Optionally, the preset rule may select multiple non-contiguous PFs whose serial numbers are each value of an arithmetic sequence. For example, a group includes 12 PFs, the arithmetic sequence is a sequence with a first term of 0 and a common difference of 3, and the arithmetic sequence is 0, 3, 6, 9, 12. Therefore, the PEI jump of the first PF in the group indicates the listening status and / or TRS acquisition status of the PO at the corresponding positions of PF3, PF6, PF9 and PF12.

[0322] Optionally, the receiving PEI includes: receiving the PEI of the corresponding PO in at least one group of PFs in at least one DRX cycle.

[0323] The specific process of receiving PEI by the terminal device is as follows:

[0324] Receive the PEI of the corresponding PO in one or more groups of PFs of a DRX cycle, where the corresponding PO in the PF can be interpreted as the PO of a preset mapping position in the PF; or receive the PEI of the corresponding PO in a group of PFs consisting of multiple DRX cycles; or receive the PEI of the corresponding PO in multiple groups of PFs of multiple DRX cycles. The PEI is located before the corresponding PO in the first PF in the same group.

[0325] In one embodiment, the step S30 includes at least one of the following:

[0326] In response to the indication information in the PEI, the identification unit monitors the PO;

[0327] Perform TRS synchronization in response to the indication information identification unit in the PEI;

[0328] In response to the indication information in the PEI, the identification unit monitors the PO and performs TRS synchronization;

[0329] In response to the indication information in the PEI, the identification unit does not monitor the PO;

[0330] In response to the indication information identification unit in the PEI, not performing TRS synchronization;

[0331] In response to the indication information in the PEI, the identification unit does not monitor the PO and does not perform TRS synchronization.

[0332] When PEI is DCI-based, multiple bits in PEI correspond to jump indications of the listening status of multiple POs at the same position of PFs, that is, if the identification unit of the indication information (such as a bit) is a first value (such as 1), then the listening status of the PO indicated by this identification unit is listening, and the PDCCH and / or PDSCH of the PO indicated by this identification unit is listened; if the identification unit of the indication information (such as a bit) is a second value (such as 0), then the listening status of the PO indicated by this identification unit is not listening, and the PDCCH and / or PDSCH of the PO indicated by this identification unit is not listened.

[0333] For example, PEI is 0101, that is, the identification unit of the indication information is 0101 in sequence, and PO1 at the same position in PF0, PF1, PF2 and PF3 is jumped and indicated in sequence. Then, the PDCCH and / or PDSCH of PO1 of PF0 is not monitored, the PDCCH and / or PDSCH of PO1 of PF1 is monitored, the PDCCH and / or PDSCH of PO1 of PF2 is not monitored, and the PDCCH and / or PDSCH of PO1 of PF3 is monitored.

[0334] Optionally, when the indication information of PEI is a reference signal sequence, the identification unit (such as a subsequence) of the reference signal sequence is a first value, then the PDCCH and / or PDSCH of the PO indicated by this identification unit is monitored; if it is a second value, then the PDCCH and / or PDSCH of the PO indicated by this identification unit is not monitored.

[0335] Based on basically the same principle, when the TRS-related indication information of PEI is a plurality of bits of DCI, the plurality of bits of the indication information correspond to the jump indication of the acquisition status of the TRS corresponding to the PO at the same position of the plurality of PFs, that is, if the identification unit (such as a bit) of the indication information is a first value (such as 1), then the acquisition status of the TRS corresponding to the PO indicated by this identification unit is obtainable, and it is determined that the TRS corresponding to the PO indicated by this identification unit is applied to the auxiliary time-frequency synchronization before PO demodulation; and / or, if the identification unit (such as a bit) of the indication information is a second value (such as 0), then the acquisition status of the TRS corresponding to the PO indicated by this identification unit is unavailable, and it is determined that the TRS corresponding to the PO indicated by this identification unit is not applied to the auxiliary time-frequency synchronization before PO demodulation.

[0336] For example, PEI is 0101, that is, the identification unit of the indication information is 0101 in sequence, and the TRS corresponding to the same position in PF0, PF1, PF2 and PF3 are jumped in sequence. Then the TRS corresponding to PO1 of PF0 is not available, the TRS corresponding to PO1 of PF1 is available, the TRS corresponding to PO1 of PF2 is not available, and the TRS corresponding to PO1 of PF3 is available.

[0337] Optionally, when the TRS-related indication information of PEI is a reference signal sequence, the identification unit (such as a subsequence) of the reference signal sequence is a first value, then the TRS corresponding to the PO indicated by this identification unit is available and can be applied to time-frequency synchronization before PO demodulation; and / or, the identification unit (such as a subsequence) of the reference signal sequence is a second value, then the TRS corresponding to the PO indicated by this identification unit is not available.

[0338] When the identification unit of PEI is used to indicate both the listening state of PO and the acquisition state of TRS, the PEI indication information is interpreted as follows (taking DCI-based PEI as an example, Sequence-based PEI has the same interpretation):

[0339] For example, PEI is 01010001, that is, the identification unit of the PO monitoring status indication information (i.e., PO indication) is 0101 in sequence, and the identification unit of the TRS acquisition status indication information (i.e., TRS acquisition indication) is 0001. PEI jumps to indicate PO1 at the same position in PF0, PF1, PF2 and PF3 in sequence. Then, PO1 of PF0 is not monitored and the TRS corresponding to PO1 of PF0 is not available, PO1 of PF1 is monitored and the TRS corresponding to PO1 of PF1 is not available, PO1 of PF2 is not monitored and the TRS corresponding to PO1 of PF2 is not available, PO1 of PF3 is monitored and the TRS corresponding to PO1 of PF3 is available and can be applied to auxiliary time and frequency synchronization before PO demodulation.

[0340] When the PF contained in the DRX cycle contains only one PO, that is, Ns=1, and the number of PFs is relatively small, such as 2, 4, 8, etc., it is only necessary to place a PEI carrying a TRS acquisition indication (that is, TRS acquisition status-related indication information) in front of at least one PO of the first PF to indicate the acquisition status of TRS within the entire DRX cycle.

[0341] When the acquisition indication of TRS corresponding to each PO is random, and each PF in the DRX cycle contains at least one PO, and the number of PFs in the DRX cycle is relatively large, for example, there are 128 PFs in each DRX cycle, it is necessary to group the PFs in the entire DRX cycle according to the bits that PEI can represent, and place PEI only in front of each PO in the first PF of each group to indicate the acquisition status of TRS of the entire group.

[0342] The PEI in this application can be used to indicate only the monitoring state of the PO, or only the acquisition state of the TRS corresponding to the PO, or both the monitoring state of the PO and the acquisition state of the TRS corresponding to the PO. Fig.11a and Fig.11b, a technical solution is given for PEI to indicate both PO listening status and TRS acquisition status at the same time, and the example is DCI-based, and the design of Sequence-based PEI has the same technical solution. In one embodiment of the technical solution, the above embodiments and Figures 5 to 10 An example is given, which shows that PEI only indicates the PO listening state or PEI only indicates the TRS acquisition state of PO; in fact, PEI can also be used to indicate both the PO listening state and the TRS acquisition state, such as Figures 14 to 16 Example.

[0343] The purpose of TRS acquisition indication is to enable the terminal device to know in advance whether TRS exists, so as to assist SSB in achieving better downlink synchronization when PO demodulation is required, thereby ensuring the success rate of PO demodulation. Based on this, this patent also proposes that whether TRS acquisition indication is required can be determined according to whether PO needs to be monitored in PEI. That is, if the bit indicating the PO monitoring status in PEI is 0, that is, there is no need to monitor PO, then the TRS acquisition indication does not need to occupy bits, and a reserved bit can be preset instead, which can further save PEI indication bits. The design scheme is also applicable to SSS-based or TRS-based PEI.

[0344] Reference Fig.11a , assuming that the PO indication bit in the PEI indication: 0 means that this PO does not need to be monitored, 1 means that this PO needs to be monitored; the TRS availability indication in the PEI: 0 bit means that TRS is not available, 1 means that TRS is available, and the reserved bit means that the current bit does not need to be occupied temporarily. Fig.11b The TRS acquisition indication given in the PEI is valid only when the PO needs to monitor, and Fig.11b The bit design is that one PO indication corresponds to one TRS availability indication, but only when the PO indication bit is 1, the TRS availability indication needs to be parsed for availability and unavailability.

[0345] In order to reduce power consumption of UE during paging, the present application also provides a processing method, which is applied to terminal equipment. In one embodiment, referring to Fig.12 , including the following steps:

[0346] S100, if the group information and the indication information meet the preset condition, determine the listening state and / or TRS acquisition state of at least one PO of the PF of at least one group according to the group information and the indication information;

[0347] S200, determining whether to monitor a paging message according to the monitoring status, and / or determining whether to perform time-frequency synchronization through the TRS according to the acquisition status of the TRS.

[0348] In one implementation, after receiving the PEI, the terminal device can know the monitoring status of the current and subsequent PO in at least one PF in advance according to the indication information, and continue to sleep in the subsequent paging occasions that do not need to be monitored, and wake up only in the subsequent paging occasions that need to be monitored. The terminal device is awakened in a targeted manner, avoiding frequent awakening and search space detection at each paging occasion, thereby reducing the power consumption of the terminal.

[0349] In another implementation, after receiving PEI, the terminal device can know in advance the acquisition status of the TRS corresponding to the current and subsequent PO in at least one PF according to the indication information. When the subsequent TRS is available and PO monitoring is required, time and frequency synchronization is achieved through TRS-assisted SSB, thereby shortening the wake-up time of the terminal device and reducing the power consumption of the terminal device.

[0350] Optionally, after the terminal device wakes up, it may only need to parse one SSB to assist in time and frequency synchronization through TRS. If there is no TRS for auxiliary time and frequency synchronization, it may need to parse three SSBs. The terminal device performs auxiliary time and frequency synchronization through TRS, which can shorten the PO demodulation time, thereby reducing the duration of the terminal device wake-up and reducing the functions of the terminal device.

[0351] In another implementation, after receiving PEI, the terminal device can know the monitoring status of the current and subsequent PO in at least one PF in advance according to the indication information. The terminal device can continue to sleep at the subsequent paging occasions that do not need to be monitored, and wake up only at the subsequent paging occasions that need to be monitored, thereby avoiding frequent wake-ups and search space detection at each PO, and reducing the power consumption of the terminal device by reducing the number of wake-ups. The indication information can also indicate in advance whether the TRS of the PO in at least one PF is available, especially for indicating in advance whether the TRS of the paging occasion that needs to be monitored in at least one PF is available, and when PO monitoring is required and the TRS acquisition status is available, time and frequency synchronization is performed directly through TRS, shortening the wake-up time of the terminal device, and reducing the power consumption of the terminal device by reducing the wake-up time.

[0352] In this embodiment, PEI is received, and the listening status of at least one PO of at least one PF and / or the acquisition status of TRS are determined through the indication information in PEI, and then whether to listen to the paging message is determined according to the listening status, and / or, whether to perform time and frequency synchronization through TRS is determined according to the acquisition status of TRS. During the paging process, the power consumption of the terminal device is reduced by reducing the number of terminal device wake-up times and / or reducing the wake-up time of the terminal device, thereby achieving the purpose of power saving of the terminal device.

[0353] This application supports the realization of TRS / CSI-RS acquisition indication through PEI (ie, TRS-related indication information in PEI), and supports one PEI to support TRS / CSI-RS acquisition indication corresponding to at least one PO. The specific implementation idea is:

[0354] If the TRS / CSI-RS acquisition indication corresponding to each PO is different, one PEI indicates the acquisition status of the TRS / CSI-RS at the corresponding position of at least one PF, which saves more signal resources than placing a PEI indicating the acquisition status of TRS / CSI-RS in front of each PO of each PF; at the same time, TRS / CSI-RS can also be used to assist downlink synchronization and shorten the PO demodulation time. The PEI jump indication TRS acquisition status is basically the same as the PEI jump indication PO monitoring status indication method.

[0355] Based on the above embodiments, the inventors found that: the indication information of a PEI can indicate at least one continuous PO in the PF, but this method of continuously indicating at least one PO occupies more available resources of the PEI. If the PEI is a DCI-based PEI (carrying paging indication by DCI bit mapping), then the PEI continuously indicates at least one PO and wastes the occupied resources of the DCI bit. For example, refer to Figure 4 If a PF has 12 POs, 144 bits are needed to indicate 12 PFs continuously, resulting in a waste of bits; if the PEI is an SSS-based PEI (PEI is carried by mapping the SSS (Secondary Synchronization Signa1) reference signal) or a TRS-based PEI, based on the SSS sequence or the TRS sequence, 144 sequences are needed to indicate continuous POs, resulting in a waste of sequences.

[0356] Based on this problem, the present application further proposes another embodiment, in which the indication information of a PEI jumps to indicate the monitoring status and / or TRS acquisition status of one or at least one PO of each PF preset mapping position in at least one PF, and the preset mapping position may be the same position in each PF (that is, the sorting position of the PO in the PF is the same), that is, the indication information is used to indicate the monitoring status of the PO at the same position of at least one PF. In an optional implementation manner, it may be at least one of the following:

[0357] The indication information jump indication of the first PEI of the first PF: the first PO of the first PF, the first PO of the second PF, the first PO of the third PF;

[0358] The indication information jump indication of the second PEI of the first PF: the second PO of the first PF, the second PO of the second PF, the second PO of the third PF;

[0359] The indication information of the third PEI of the first PF jumps to indicate: the third PO of the first PF, the third PO of the second PF, and the third PO of the third PF.

[0360] The above is only a detailed explanation of the same position, which may include but is not limited to three PFs, and also includes but is not limited to three POs for each PF.

[0361] Optionally, the preset mapping position may also be a non-identical position in each PF, as long as the PEI completes the jump indication of all POs in at least one PF. For example, the indication information of the PEI jumps to indicate the POs at positions where the sorting positions in at least one PF are incremented one by one until all POs in the PF are traversed, that is, the indication information is used to indicate the monitoring status of POs at different positions of at least one PF. In an optional implementation, it may be at least one of the following:

[0362] The indication information jump indication of the first PEI of the first PF: the first PO of the first PF, the second PO of the second PF, and the third PO of the third PF;

[0363] The indication information jump indication of the second PEI of the first PF: the second PO of the first PF, the third PO of the second PF, and the first PO of the third PF;

[0364] The indication information of the third PEI of the first PF jumps to indicate: the third PO of the first PF, the first PO of the second PF, and the second PO of the third PF.

[0365] The above is only a detailed explanation of non-identical positions, which may include but are not limited to three PFs, and also include but are not limited to three POs per PF.

[0366] In this embodiment, the indication information of a PEI jumps to indicate at least one PO of the preset mapping position of each PF in at least one PF, saving the available signal resources of the PEI. For example, taking DCI-based PEI as an example, there are 2 PFs, each PF has 4 POs, and 8 DCI bits are required to continuously indicate 2 PFs through one PEI. However, if the first PO of the 2 PFs is indicated by one PEI, then the 2 PFs only need 2 DCI bits. Similarly, PEI jumps to indicate PO of multiple PFs with SSS-based PEI or TRS-based PEI, which can also save sequence resources. In other words, by jumping to indicate the PO of the preset mapping position of each PF in at least one PF through the indication information of one PEI, DCI bits or reference signal sequences can be saved, that is, PEI jumps to indicate PO, which can save signal resources used for indication.

[0367] To help understand the technical solution, we will take a specific PEI scenario as an example:

[0368] In the scenario where a PF has only one PEI:

[0369] Reference Figure 5 , SearcheSpaceId=0,Ns=1,N=T / 16,T=32,then N=32 / 16=2,that is, when DRXCycle=32 radio frames, there are N=2 PFs in one DRX Cycle, and each PF has Ns=1 PO. The PEI jump before the first PO of PF0 indicates the monitoring status of a single PO of PF0 and PF1.

[0370] Reference Fig. 9 , SearcheSpaceId=0,Ns=1,N=T / 16,T=32,then N=32 / 16=2, that is, when DRXCycle=32 radio frames, there are N=2 PFs in a DRX Cycle, and each PF has Ns=1 PO. The PEI jump before the first PO of PF0 indicates whether the TRS corresponding to the single PO of PF0 and PF1 is available.

[0371] Optionally, the PEI jump indicates the monitoring status of at least one PO of each PF preset mapping position in at least one PF and the acquisition status of the TRS, that is, Figure 5 and Fig. 9 PEI indicates both the listening state of PO and the acquisition state of TRS. Fig.14, SearcheSpaceId=0, Ns=1, N=T / 16, T=32, then N=32 / 16=2, that is, when DRXCycle=32 wireless frames, there are N=2 PFs in a DRX Cycle, each PF has Ns=1 PO, and the PEI before the first PO of PF0 jumps to indicate the monitoring status of the single PO of PF0 and PF1, and then jumps to indicate whether the TRS corresponding to the single PO of PF0 and PF1 is available.

[0372] Optionally, the monitoring state may include at least one of the following: monitoring, no need for monitoring, or partial monitoring and partial no need for monitoring, and / or the acquisition state may include at least one of the following: available, unavailable, or partially available and partially unavailable.

[0373] In the scenario where a PF includes multiple PEIs:

[0374] Reference Figure 6 , SearcheSpaceId=1,Ns=4,N=T / 8;T=32;then N=32 / 8=4, that is, when DRX Cycle=32 radio frames, there are N=4 PFs in one DRX Cycle, and each PF has Ns=4 POs. The indication information of PEI before PO0 of PF0 jumps to indicate PO0 of PF0 to PF3, the indication information of PEI before PO1 of PF0 jumps to indicate PO1 of PF0 to PF3, the indication information of PEI before PO2 of PF0 jumps to indicate PO2 of PF0 to PF3, the indication information of PEI before PO3 of PF0 jumps to indicate PO3 of PF0 to PF3, PF0 to PF3 are in the same DRX cycle, and PF0 to PF3 are also in the same group. Optionally, regarding PFs of multiple DRX cycles belonging to one or more groups, the jump indication logic of the indication information of PEI is basically the same, which will not be described in detail here.

[0375] Optionally, the inventors have found that if a PEI indicates multiple POs continuously, it may only indicate part of the PFs in a DRX cycle. In a scenario with a very low paging rate, the terminal device only knows the monitoring status of at least one PO of part of the PFs in a DRX cycle and / or whether time-frequency synchronization is performed through TRS. It is only possible to avoid unnecessary wake-up times and / or unnecessary wake-up time for at least one PO of a small part of the PFs in a DRX cycle, and the purpose of better power consumption reduction cannot be achieved. In one embodiment, to address this deficiency, the method for determining or generating the grouping information includes at least one of the following:

[0376] determining a PF of at least one packet in at least one DRX cycle;

[0377] A PF of at least one packet in at least one DRX cycle is generated according to the first number and / or the second number.

[0378] Before receiving PEI, the terminal device may first determine the grouping status of PF. A PEI may indicate the monitoring status of at least one PO of multiple PFs in a group and / or the acquisition status of TRS. For example, a PEI indicates the PO of the preset mapping position of multiple PFs in a group. It may be that PFs in a DRX cycle form a group, or PFs in a DRX cycle form multiple groups, or PFs in multiple DRX cycles form a group.

[0379] Since the indication information of a PEI jumps to indicate non-continuous POs of multiple PFs in a group, each PEI is only used to indicate the listening status of a PO of each PF in a group and / or the acquisition status of TRS, so each PEI can indicate the PF of the entire or most of the DRX cycle. In this way, when the terminal device is in a low paging rate scenario, it is only necessary to parse the Ns POs in the first PF in the group (each PF corresponds to Ns POs), so as to know the listening status and / or the acquisition status of TRS of Ns POs in the PF in a DRX cycle or multiple DRX cycles, thereby avoiding the terminal device from being awakened at a paging time when no monitoring is required, so that the terminal device can be in a dormant state for a longer time, thereby reducing power consumption; and / or the terminal device obtains the acquisition status of TRS corresponding to the PO according to the PEI, and uses TRS for auxiliary time and frequency synchronization, thereby shortening the wake-up time and saving power consumption.

[0380] To assist in understanding the technical solution, a specific PEI scenario is taken as an example. In a scenario where a PF includes multiple PEIs and a DRX cycle includes multiple groups, refer to Figure 7 , SearcheSpaceId=0, Ns=2, N=T / 4, T=256, then N=256 / 4=64, that is, when the DRX cycle = 256 wireless frames, there are N=64 PFs in one DRX cycle, and each PF has Ns=2 POs. Then the PO in the entire DRX cycle is divided into two parts (i.e., group 1 and group 2) for PEI indication.

[0381] It should be noted that in Figure 7 In the example, the indication information of PEI can indicate the TRS of each PF in group 1 and group 2. Fig.10 For example, see Fig.10 , SearcheSpaceId=0, Ns=2, N=T / 4, T=256, then N=256 / 4=64, that is, when DRXCycle=256 wireless frames, there are N=64 PFs in a DRX Cycle, and each PF has Ns=2 POs. Then the PO in the entire DRXCycle is divided into two parts (i.e., group 1 and group 2) for PEI indication.

[0382] against Fig.10 In one embodiment, if PEI is DCI-based and the number of bits used for PEI indication is 48, then a PEI can indicate L=32 PFs. The embodiment design diagram is only used to indicate the scheduling process, and does not indicate that the scheduled PFs are scheduled in parallel, that is, PF0, PF1, ......., PF63 are arranged in chronological order. Fig.10 The grouping method and PEI jump indication TRS indication method also apply to Figure 7 , Figure 8a and Figure 8b , Figure 7 , Figure 8a and Figure 8b PEI can synchronously indicate the acquisition status of TRS corresponding to PO. Fig.10 The applicability of grouping and indication methods can be found in Fig.10 Add PEI jump indication to indicate the monitoring status of at least one PO of each PF group, please refer to Fig.15 , the PEI jump indicates the monitoring status of the PO and the acquisition status of the TRS at the corresponding position of each PF in each group.

[0383] For example, refer to Figure 8a and Figure 8b , SearcheSpaceId=1, Ns=4, N=T / 2, T=256, then N=256 / 2=128, that is, when DRX cycle=256 radio frames, there are N=128 PFs in a DRX Cycle, and each PF has Ns=4 POs. Then the PO in the entire DRX Cycle is divided into four parts (group 1, group 2, group 3 and group 4) for PEI indication.

[0384] Regarding the method for generating the grouping information: according to the first number and / or the second number, a PF of at least one group in at least one DRX cycle is generated.

[0385] The first number is the number of PFs included in the DRX cycle, and the second number is the number of identifiers carrying the indication information of the PEI. Based on the first number and / or the second number, determine which paging frames of the DRX cycle the PF of at least one packet in at least one DRX cycle is, such as determining the number L of PFs of a packet based on the first number and the second number.

[0386] For ease of understanding, assume that the first number is N, the second number is G, and the total number of radio frames in a DRX cycle is T. Based on the protocol relationship in Table 2, it can be seen that N, the number of PFs in a group is L, and L=2 x<=G. For the scenario where there are more than L PFs in a DRX cycle (i.e., N>L), a classification indication can be made for each L PF to form a group. The advantage of indicating only the L PFs of the entire DRX cycle is that DCI bits or reference signal sequences are saved, so that at most only L DCI bits or reference signal sequences are needed to indicate the entire DRX cycle. The value of L depends on the number of DCI bits or reference signal sequences ultimately used to carry PEI (i.e., the second number G). For example, based on L=2 x <=G, DCI-based PEI has 48 bits (ie, G=48), then L is 32; DCI-based PEI has 12 bits (ie, G=12), then L is 8.

[0387] against Figure 7 The embodiment is given assuming that the number of DCI-based PEI bits is 48 and one PEI indicates L=32 PFs. The embodiment design diagram is only used to show the scheduling process, and does not mean that the scheduled PFs are scheduled in parallel, that is, PF0, PF1, ......., PF63 are arranged in chronological order.

[0388] Optionally, the meanings of Paging related parameters are summarized according to 38.304 and 38.331 protocols, as shown in Table 3. According to possible values ​​of high-level signaling, the number of PFs that may exist in a DRX cycle is summarized in Table 4.

[0389] As can be seen from Table 4, there may be too many PFs in a DRX cycle. In order to save DCI bits or reference signal sequences, classification is made according to the different numbers of PFs in the DRX cycle. The purpose is to use as many bits or reference signal sequences as possible to indicate the PF in the DRX cycle, so as to ensure that the terminal equipment can be in sleep state for a longer time under low paging rate, so as to reduce power consumption.

[0393]

[0394] In one embodiment, the satisfying of the preset condition includes at least one of the following:

[0395] At least one PF indicated by the indication information exists in the at least one group;

[0396] The PEI is located before the corresponding PO in the first PF in the same group, and the at least one PF indicated by the indication information exists in the at least one group.

[0397] (1) If there is only one group in a DRX cycle, a PEI is placed before each of the Ns PO monitoring of the first PF in a DRX cycle. The indication information of this PEI indicates whether the PO at the corresponding position of each PF in the entire DRX cycle needs to be monitored and / or whether the corresponding TRS / CSI-RS is available. The terminal device is awakened and monitors only when the paging time that needs to be monitored is required, and / or when PO monitoring is required and TRS is available, auxiliary time and frequency synchronization is performed through TRS.

[0398] (2) If multiple DRX cycles belong to the same group, a PEI is placed before each of the Ns PO monitoring of the first PF of the first DRX cycle in timing, and the indication information of this PEI indicates whether the PO at the corresponding position of each PF of the multiple DRX cycles needs to be monitored and / or whether the corresponding TRS is available. The terminal device is awakened and monitors only when the paging opportunity that needs to be monitored is required, and / or when PO monitoring is required and TRS is available, auxiliary time and frequency synchronization is performed through TRS.

[0399] (3) If a DRX cycle contains multiple groups, a PEI is placed before the Ns PO monitoring of the first PF of each group. The indication information of this PEI indicates whether the PO at the corresponding position of each PF of each group needs to be monitored and / or whether the corresponding TRS is available. The terminal device is awakened and monitors only when the paging opportunity needs to be monitored, and / or performs time and frequency synchronization through TRS when PO monitoring is required and TRS is available.

[0400] Optionally, before step S100, the processing method further includes: receiving PEI, specifically: receiving PEI of a PO corresponding to at least one group of PFs in at least one DRX cycle.

[0401] The specific process of receiving PEI by the terminal device is as follows:

[0402] Receive the PEI of the corresponding PO in one or more groups of PFs of a DRX cycle, where the corresponding PO in the PF can be interpreted as the PO of a preset mapping position in the PF; or receive the PEI of the corresponding PO in a group of PFs consisting of multiple DRX cycles; or receive the PEI of the corresponding PO in multiple groups of PFs of multiple DRX cycles. The PEI is located before the corresponding PO in the first PF in the same group.

[0429] In one implementable embodiment, the indication information of PEI can instruct the terminal device to: listen to at least one PO of different PFs in at least one group and do not perform auxiliary time and frequency synchronization based on at least one TRS of different PFs in at least one group, and do not listen to at least one PO of different PFs in at least one group and do not perform auxiliary time and frequency synchronization based on at least one TRS of different PFs in at least one group, that is, the listening status of multiple POs of different PFs in at least one group is partial listening and partial no need to listen, the acquisition status of at least one TRS of different PFs in at least one group is unavailable, the terminal device listens to at least one PO of different PFs in at least one group and indicates that at least one TRS of different PFs in at least one group is unavailable, and does not listen to at least one PO of different PFs in at least one group and indicates that at least one TRS of different PFs in at least one group is unavailable.

[0430] In one implementable embodiment, the indication information of PEI can instruct the terminal device: not to monitor at least one PO of different PFs in at least one group and to perform auxiliary time-frequency synchronization based on at least one TRS of different PFs in at least one group, and not to monitor at least one PO of different PFs in at least one group and to perform auxiliary time-frequency synchronization based on at least one TRS of different PFs in at least one group, that is, the monitoring status of at least one PO of different PFs in at least one group is that no monitoring is required, and the acquisition status of multiple TRS of different PFs in at least one group is that some are available and some are not available, the terminal device does not monitor at least one PO of different PFs in at least one group and indicates that at least one TRS of different PFs in at least one group is available, and does not monitor at least one PO of different PFs in at least one group and indicates that at least one TRS of different PFs in at least one group is not available.

PEI can be located before each PO in the first PF in the same group, and provides an implementation method for PEI to jump to indicate at least one PO of different PFs, saving the number of identifiers carrying PEI (such as DCI bit or reference signal sequence), ensuring that the terminal device can be in a sleep state for a longer time under a low paging rate and / or can perform PO demodulation in a shorter time to reduce power consumption.

[0432] Optionally, the step S100 includes:

[0433] S101, determining a PF of at least one group in at least one DRX cycle according to the group information;

[0434] S102: Determine, according to the indication information, the listening state of at least one PO of at least one PF of at least one group in the same or different DRX cycles and / or the acquisition state of TRS.

[0435] Optionally, step S102 includes at least one of the following:

[0436] If the PF within the configured DRX cycle is configured as a single group, the indication information in the PEI before each PO in the first PF of the single group is parsed to determine the listening status of the PO at the corresponding position of each PF of the single group and / or the acquisition status of the TRS; optionally, the listening status may include at least one of the following: listening, no need for listening, or partial listening and partial no need for listening, and / or, the acquisition status may include at least one of the following: available, unavailable, or partially available and partially unavailable.

[0437] If the PF within the configured DRX cycle is configured as multiple groups, the indication information in the PEI before each PO in the first PF of each group is parsed to determine the listening status and / or TRS acquisition status of the PO at the corresponding position of each PF of each group.

[0438] Optionally, step S102 includes at least one of the following:

[0439] If the PF in the configured DRX cycle is configured as a single group, the indication information in the PEI before each PO in the first PF of the single group is parsed to determine the monitoring status and / or TRS acquisition status of the POs at the corresponding positions of the non-continuous multiple PFs selected by the predetermined rule of the single group;

[0440] If the PF within the configured DRX cycle is configured as multiple groups, the indication information in the PEI before each PO in the first PF of each group is parsed to determine the listening status and / or TRS acquisition status of the PO at the corresponding positions of multiple non-continuous PFs selected by the predetermined rules of each group.

[0441] Optionally, the predetermined rule may be to determine multiple non-continuous PFs by selecting odd or even numbers of PF sequence numbers in the group, selecting an arithmetic progression, etc., to distinguish each continuous PF in the group. The predetermined rule selects multiple non-continuous PFs that are applicable to the situations of a single group and multiple groups.

[0442] In the preset rule one feasible method, the preset rule is an odd-even selection method, that is, a PF with an odd or even number is selected in a group, the PEI before each PO before the first PF in this group is parsed, and the listening status and / or TRS acquisition status of the POs at the corresponding positions of multiple non-continuous PFs with odd or even numbers are determined.

[0443] In an optional embodiment, the preset rule is to select a plurality of non-continuous PFs with odd sequence numbers, referring to Fig.16 , a group includes 6 PFs, each PF has 2 POs, and the PFs in the group are PF0, PF1, PF2, PF3, PF4, and PF5. The PEI jumps before PO0 and PO1 in the first PF0 of this group indicate the monitoring status of the POs at the corresponding positions in PF1, PF3, and PF5 and the acquisition status of TRS. It should be noted that in this optional embodiment, only a detailed explanation of selecting non-continuous multiple PFs according to the preset rules is provided, which may include but is not limited to 6 PFs, and also includes but is not limited to 2 POs for each PF.

[0444] Optionally, the preset rule may be to select multiple non-contiguous PFs with even serial numbers, for example, a group includes 12 PFs, and the PEI jump of the first PF in the group indicates the listening status and / or TRS acquisition status of the PO at the corresponding positions of PF2, PF4, PF6, PF8, PF10 and PF12.

[0445] Optionally, the preset rule may select multiple non-contiguous PFs whose serial numbers are each value of an arithmetic sequence. For example, a group includes 12 PFs, the arithmetic sequence is a sequence with a first term of 0 and a common difference of 3, and the arithmetic sequence is 0, 3, 6, 9, 12. Therefore, the PEI jump of the first PF in the group indicates the listening status and / or TRS acquisition status of the PO at the corresponding positions of PF3, PF6, PF9 and PF12.

[0446] In one embodiment, the step S200 includes at least one of the following:

[0447] In response to the indication information identification unit monitoring PO;

[0448] Performing TRS synchronization in response to the indication information identification unit;

[0449] In response to the indication information, the identification unit monitors the PO and performs TRS synchronization;

[0450] In response to the indication information, the identification unit does not monitor the PO;

[0451] In response to the indication information, the identification unit does not perform TRS synchronization;

[0452] In response to the indication information, the identification unit does not monitor the PO and does not perform TRS synchronization.

[0453] When PEI is DCI-based, multiple bits in PEI correspond to jump indications of the listening status of multiple POs at the same position of PFs, that is, if the identification unit (such as a bit) of the indication information is a first value (such as 1), then the listening status of the PO indicated by this identification unit is listening, and the PDCCH and / or PDSCH of the PO indicated by this identification unit is listened; and / or, if the identification unit (such as a bit) of the indication information is a second value (such as 0), then the listening status of the PO indicated by this identification unit is not listened, and the PDCCH and / or PDSCH of the PO indicated by this identification unit is not listened.

[0454] For example, PEI is 0101, that is, the identification unit of the indication information is 0101 in sequence, and PO1 at the same position in PF0, PF1, PF2 and PF3 is jumped and indicated in sequence. Then, the PDCCH and / or PDSCH of PO1 of PF0 is not monitored, the PDCCH and / or PDSCH of PO1 of PF1 is monitored, the PDCCH and / or PDSCH of PO1 of PF2 is not monitored, and the PDCCH and / or PDSCH of PO1 of PF3 is monitored.

[0455] Optionally, when the indication information of PEI is a reference signal sequence, the identification unit (such as a subsequence) of the reference signal sequence is a first value, then the PDCCH and / or PDSCH of the PO indicated by this identification unit is monitored, and / or, the identification unit (such as a subsequence) of the reference signal sequence is a second value, then the PDCCH and / or PDSCH of the PO indicated by this identification unit is not monitored.

[0456] Based on basically the same principle, when the TRS-related indication information of PEI is a plurality of bits of DCI, the plurality of bits of the indication information correspond to the jump indication of the acquisition status of the TRS corresponding to the PO at the same position of the plurality of PFs, that is, if the identification unit (such as a bit) of the indication information is a first value (such as 1), then the acquisition status of the TRS corresponding to the PO indicated by this identification unit is obtainable, and it is determined that the TRS corresponding to the PO indicated by this identification unit is applied to the auxiliary time-frequency synchronization before PO demodulation; and / or, if the identification unit (such as a bit) of the indication information is a second value (such as 0), then the acquisition status of the TRS corresponding to the PO indicated by this identification unit is unavailable, and it is determined that the TRS corresponding to the PO indicated by this identification unit is not applied to the auxiliary time-frequency synchronization before PO demodulation.

[0457] For example, PEI is 0101, that is, the identification unit of the indication information is 0101 in sequence, and the TRS corresponding to the same position in PF0, PF1, PF2 and PF3 are jumped in sequence. Then the TRS corresponding to PO1 of PF0 is not available, the TRS corresponding to PO1 of PF1 is available, the TRS corresponding to PO1 of PF2 is not available, and the TRS corresponding to PO1 of PF3 is available.

[0458] Optionally, when the TRS-related indication information of PEI is a reference signal sequence, the identification unit (such as a subsequence) of the reference signal sequence is a first value, then the TRS corresponding to the PO indicated by this identification unit is available and can be applied to time-frequency synchronization before PO demodulation; if the identification unit (such as a subsequence) of the reference signal sequence is a second value, then the TRS corresponding to the PO indicated by this identification unit is not available.

[0459] When the identification unit of PEI is used to indicate both the listening state of PO and the acquisition state of TRS, the PEI indication information is interpreted as follows: (taking DCI-based PEI as an example, Sequence-based PEI has the same interpretation)

[0460] For example, PEI is 01010001, that is, the identification unit of the PO monitoring status indication information (i.e., PO indication) is 0101 in sequence, and the identification unit of the TRS acquisition status indication information (i.e., TRS acquisition indication) is 0001. PEI jumps to indicate PO1 at the same position in PF0, PF1, PF2 and PF3 in sequence. Then, PO1 of PF0 is not monitored and the TRS corresponding to PO1 of PF0 is not available, PO1 of PF1 is monitored and the TRS corresponding to PO1 of PF1 is not available, PO1 of PF2 is not monitored and the TRS corresponding to PO1 of PF2 is not available, PO1 of PF3 is monitored and the TRS corresponding to PO1 of PF3 is available and can be applied to auxiliary time and frequency synchronization before PO demodulation.

[0461] When the PF contained in the DRX cycle contains only one PO, that is, Ns=1, and the number of PFs is relatively small, such as 2, 4, 8, etc., it is only necessary to place a PEI carrying a TRS acquisition indication (that is, TRS acquisition status-related indication information) in front of at least one PO of the first PF to indicate the acquisition status of TRS within the entire DRX cycle.

[0462] When the acquisition indication of TRS corresponding to each PO is random, and each PF in the DRX cycle contains at least one PO, and the number of PFs in the DRX cycle is relatively large, for example, there are 128 PFs in each DRX cycle, it is necessary to group the PFs in the entire DRX cycle according to the bits that PEI can represent, and place PEI only in front of each PO in the first PF of each group to indicate the acquisition status of TRS of the entire group.

[0463] The PEI in this application can be used to indicate only the monitoring state of the PO, or only the acquisition state of the TRS corresponding to the PO, or both the monitoring state of the PO and the acquisition state of the TRS corresponding to the PO. Fig.11a and Fig.11b , a technical solution is given for PEI to indicate both PO listening status and TRS acquisition status at the same time, and the example is DCI-based, and the design of Sequence-based PEI has the same technical solution. In one embodiment of the technical solution, the above embodiments and Figures 5 to 10 An example is given, which shows that PEI only indicates the PO listening state or PEI only indicates the TRS acquisition state of PO. In fact, PEI can also be used to indicate both the PO listening state and the TRS acquisition state, such as Figures 14 to 16 Example.

[0464] The purpose of TRS acquisition indication is to enable the terminal device to know in advance whether TRS exists, so as to assist SSB in achieving better downlink synchronization when PO demodulation is required, thereby ensuring the success rate of PO demodulation. Based on this, this patent also proposes that whether TRS acquisition indication is required can be determined according to whether PO needs to be monitored in PEI. That is, if the bit indicating the PO monitoring status in PEI is 0, that is, there is no need to monitor PO, then the TRS acquisition indication does not need to occupy bits, and a reserved bit can be preset instead, which can further save PEI indication bits. The design scheme is also applicable to SSS-based or TRS-based PEI.

[0465] Reference Fig.11a , assuming that the PO indication bit in the PEI indication: 0 means that this PO does not need to be monitored, 1 means that this PO needs to be monitored; the TRS availability indication in the PEI: 0 bit means that TRS is not available, 1 means that TRS is available, and the reserved bit means that the current bit does not need to be occupied temporarily. Fig.11b The TRS acquisition indication given in the PEI is valid only when the PO needs to monitor, and Fig.11b The bit design is that one PO indication corresponds to one TRS availability indication, but only when the PO indication bit is 1, the TRS availability indication needs to be parsed for availability and unavailability.

[0466] In order to reduce power consumption of UE during the process of receiving paging message, the present application also provides a processing method, which is applied to network equipment, referring to Fig.13 , the method comprises the following steps:

[0467] A10, sending a PEI to a terminal device, so that the terminal device determines a listening state of at least one PO of at least one PF and / or an acquisition state of a TRS according to indication information in the PEI;

[0468] The monitoring state is used to indicate whether to monitor a paging message, and / or the acquisition state is used to indicate whether the TRS is obtainable.

[0469] Optionally, the network device sends a PEI to the terminal device; the PEI is used to determine the listening state of at least one PO of at least one PF and / or the acquisition state of the TRS;

[0470] The monitoring state is used to indicate whether the terminal device determines whether to monitor a paging message, and / or the acquisition state is used to indicate whether the TRS is available.

[0471] Optionally, the network device sends a PEI to the terminal device, wherein the PEI includes indication information, and the indication information of the PEI is used to determine the listening status of at least one PO of at least one PF and / or the acquisition status of TRS; the listening status is used to instruct the terminal device to determine whether to listen to a paging message, and / or, the acquisition status is used to instruct the terminal device to determine whether the TRS is available.

[0472] In one implementation, the indication information can be used to indicate the listening status of the PO in at least one PF at the current moment and after the current moment, that is, the indication information can indicate in advance whether the PO in at least one PF needs to be listened to. After receiving the PEI, the terminal device can know in advance the listening status of the PO in at least one subsequent PF according to the indication information. The terminal device can continue to remain dormant during the subsequent paging period when the listening status is not listening, and only wake up at the subsequent paging period when listening is required. Therefore, the terminal device can be specifically awakened according to the indication information in the PEI and the listening status of the PO, thereby avoiding frequent waking up for search space detection at each paging period, thereby achieving power consumption saving of the terminal device.

[0473] In another implementation, the indication information can also be used to indicate the acquisition status of the TRS corresponding to the PO in at least one PF at the current moment and after the current moment, that is, the indication information can indicate in advance whether the TRS of the PO in at least one PF is available. After receiving the PEI, the terminal device knows in advance the acquisition status of the TRS corresponding to the PO in at least one subsequent PF according to the indication information. When the subsequent TRS is available and PO monitoring is required, the TRS can be used to perform auxiliary time-frequency synchronization, quickly achieve downlink synchronization, and complete PO demodulation. In this way, the number of SSBs used by the terminal device for downlink synchronization can be reduced, the synchronization time of the terminal device can be shortened, and the power consumption of the terminal device can be reduced.

[0474] Optionally, if the terminal device has TRS for auxiliary time and frequency synchronization, it may only need to parse one SSB, but if it does not have TRS for auxiliary time and frequency synchronization, it may need to parse three SSBs, thereby reducing the number of SSBs used for downlink synchronization, shortening the downlink synchronization duration, and thereby reducing the time it takes to wake up the terminal device.

[0475] In another implementation, the indication information may indicate the monitoring status of the PO in at least one PF before and after the current moment and the acquisition status of the corresponding TRS, that is, the indication information may indicate in advance whether the PO in at least one PF needs to be monitored and whether the corresponding TRS is available. After receiving the PEI, the terminal device may know in advance the monitoring status of the PO in at least one subsequent PF according to the indication information. The terminal device may continue to remain dormant during subsequent paging occasions that do not require monitoring, and only wake up during subsequent paging occasions that require monitoring, thereby avoiding frequent wake-ups and search space detection at each paging occasion, increasing the sleep time of the paging occasion, and reducing the power consumption of the terminal device. The indication information may also indicate in advance whether the TRS corresponding to the PO in at least one PF is available, and is particularly used to indicate in advance whether the TRS corresponding to the PO that at least one PF needs to monitor is available. At the paging occasion when monitoring is required and TRS is available, the terminal device may choose to perform auxiliary time-frequency synchronization through TRS to shorten the duration of PO demodulation by the terminal device, thereby saving power consumption of the terminal device.

[0476] This application supports the realization of TRS / CSI-RS acquisition indication through PEI (ie, TRS-related indication information in PEI), and supports one PEI to support TRS / CSI-RS acquisition indication corresponding to at least one PO. The specific implementation ideas are as follows:

[0477] If the TRS / CSI-RS acquisition indication corresponding to each PO is different, one PEI indicates the acquisition status of the TRS / CSI-RS at the corresponding position of at least one PF, which saves more signal resources than placing a PEI indicating the acquisition status of TRS / CSI-RS in front of each PO of each PF; at the same time, TRS / CSI-RS can also be used to assist downlink synchronization and shorten the PO demodulation time. The PEI jump indication TRS acquisition status is basically the same as the PEI jump indication PO monitoring status indication method.

[0478] Based on the above embodiments, the inventors found that: the indication information of a PEI can indicate at least one continuous PO in the PF, but this method of continuously indicating at least one PO occupies more available resources of the PEI. If the PEI is a DCI-based PEI (carrying paging indication by DCI bit mapping), then the PEI continuously indicates at least one PO and wastes the occupied resources of the DCI bit. For example, refer to Figure 4 If a PF has 12 POs, 144 bits are needed to indicate 12 PFs continuously, resulting in a waste of bits; if the PEI is an SSS-based PEI (PEI is carried by mapping the SSS (Secondary Synchronization Signa1) reference signal) or a TRS-based PEI, based on the SSS sequence or the TRS sequence, 144 sequences are needed to indicate continuous POs, resulting in a waste of sequences.

[0479] Based on this problem, the present application further proposes another embodiment, in which the indication information of a PEI jumps to indicate the monitoring status and / or TRS acquisition status of at least one PO of each PF preset mapping position in at least one PF, and the preset mapping position may be the same position in each PF (that is, the sorting position of the PO in the PF is the same), that is, the indication information is used to indicate the monitoring status of the PO at the same position of at least one PF. In an optional implementation manner, it may be at least one of the following:

[0480] The indication information jump indication of the first PEI of the first PF: the first PO of the first PF, the first PO of the second PF, the first PO of the third PF;

[0481] The indication information jump indication of the second PEI of the first PF: the second PO of the first PF, the second PO of the second PF, the second PO of the third PF;

[0482] The indication information of the third PEI of the first PF jumps to indicate: the third PO of the first PF, the third PO of the second PF, and the third PO of the third PF.

[0483] The above is only a detailed explanation of the same position, which may include but is not limited to three PFs, and also includes but is not limited to three POs for each PF.

[0484] Optionally, the preset mapping position may also be a non-identical position in each PF, as long as the PEI completes the jump indication of all POs in at least one PF. For example, the indication information of the PEI jumps to indicate the POs at positions where the sorting positions in at least one PF are incremented one by one until all POs in the PF are traversed, that is, the indication information is used to indicate the monitoring status of POs at different positions of at least one PF. In an optional implementation, it may be at least one of the following:

[0485] The indication information jump indication of the first PEI of the first PF: the first PO of the first PF, the second PO of the second PF, and the third PO of the third PF;

[0486] The indication information jump indication of the second PEI of the first PF: the second PO of the first PF, the third PO of the second PF, and the first PO of the third PF;

[0487] The indication information of the third PEI of the first PF jumps to indicate: the third PO of the first PF, the first PO of the second PF, and the second PO of the third PF.

[0488] The above is only a detailed explanation of non-identical positions, which may include but are not limited to three PFs, and also include but are not limited to three POs per PF.

[0489] In this embodiment, the indication information of a PEI jumps to indicate at least one PO of the preset mapping position of each PF in at least one PF, thereby saving the available resources of the PEI. For example, taking DCI-based PEI as an example, there are 2 PFs, each PF has 4 POs, and 8 DCI bits are required to continuously indicate 2 PFs through one PEI. However, by jumping to indicate the first PO of the 2 PFs through one PEI, the 2 PFs only need 2 DCI bits. Similarly, PEI jumps to indicate PO of multiple PFs with SSS-based PEI or TRS-based PEI, which can also save sequence resources. In other words, by jumping to indicate the PO of the preset mapping position of each PF in at least one PF through the indication information of one PEI, DCI bits or reference signal sequences can be saved, that is, PEI jumps to indicate PO, which can save signal resources used for indication.

[0490] To help understand the technical solution, let's take a specific PEI scenario as an example:

[0491] In the scenario where a PF has only one PEI:

[0492] Reference Figure 5, SearcheSpaceId=0,Ns=1,N=T / 16,T=32,then N=32 / 16=2,that is, when DRXCycle=32 radio frames, there are N=2 PFs in one DRX Cycle, and each PF has Ns=1 PO. The PEI jump before the first PO of PF0 indicates the monitoring status of a single PO of PF0 and PF1.

[0493] Reference Fig. 9 , SearcheSpaceId=0,Ns=1,N=T / 16,T=32,then N=32 / 16=2, that is, when DRXCycle=32 radio frames, there are N=2 PFs in a DRX Cycle, and each PF has Ns=1 PO. The PEI jump before the first PO of PF0 indicates whether the TRS corresponding to the single PO of PF0 and PF1 is available.

[0494] Optionally, the PEI jump indicates the monitoring status of at least one PO of each PF preset mapping position in at least one PF and the acquisition status of the TRS, that is, Figure 5 and Fig. 9 PEI indicates both the listening state of PO and the acquisition state of TRS. Fig.14 , SearcheSpaceId=0, Ns=1, N=T / 16, T=32, then N=32 / 16=2, that is, when DRXCycle=32 wireless frames, there are N=2 PFs in a DRX Cycle, each PF has Ns=1 PO, and the PEI before the first PO of PF0 jumps to indicate the monitoring status of the single PO of PF0 and PF1, and then jumps to indicate whether the TRS corresponding to the single PO of PF0 and PF1 is available.

[0495] Optionally, the monitoring state may include at least one of the following: monitoring, no need for monitoring, or partial monitoring and partial no need for monitoring; the acquisition state may include at least one of the following: obtainable, unobtainable, or partial obtainable and partial unobtainable.

[0496] In the scenario where a PF includes multiple PEIs:

[0497] Reference Figure 6, SearcheSpaceId=1,Ns=4,N=T / 8;T=32;then N=32 / 8=4, that is, when DRX Cycle=32 radio frames, there are N=4 PFs in one DRX Cycle, and each PF has Ns=4 POs. The indication information of PEI before PO0 of PF0 jumps to indicate PO0 of PF0 to PF3, the indication information of PEI before PO1 of PF0 jumps to indicate PO1 of PF0 to PF3, the indication information of PEI before PO2 of PF0 jumps to indicate PO2 of PF0 to PF3, the indication information of PEI before PO3 of PF0 jumps to indicate PO3 of PF0 to PF3, PF0 to PF3 are in the same DRX cycle, and PF0 to PF3 are also in the same group. Optionally, regarding PFs of multiple DRX cycles belonging to one or more groups, the jump indication logic of the indication information of PEI is basically the same, which will not be described in detail here.

[0498] Optionally, the inventors have found that if a PEI indicates multiple POs continuously, it may only indicate part of the PFs in a DRX cycle. In a scenario where the paging rate is very low, the terminal device only knows the monitoring status of at least one PO of part of the PFs in a DRX cycle and / or whether time-frequency synchronization is performed through TRS. It can only avoid unnecessary wake-up times and / or unnecessary wake-up time for at least one PO of a small part of the PFs in a DRX cycle, and cannot achieve the purpose of better power consumption reduction. In one embodiment, to solve this problem, before step A10, it also includes:

[0499] A00, determine the grouping status of at least one DRX cycle.

[0500] Before the network device sends PEI to the terminal device, the network device may first configure the grouping status of PF. One PEI may indicate the monitoring status of at least one PO of multiple PFs in a group and / or the acquisition status of TRS. For example, one PEI indicates the PO of the preset mapping position of multiple PFs in a group. It may be that PFs within a DRX cycle form one group, or PFs within a DRX cycle form multiple groups, or PFs within multiple DRX cycles form one group.

[0501] Since the indication information of a PEI jumps to indicate non-continuous POs of multiple PFs in a group, each PEI is only used to indicate the listening status of a PO of each PF in a group and / or the acquisition status of TRS, so each PEI can indicate the PF of the entire or most of the DRX cycle. In this way, when the terminal device is in a low paging rate scenario, it is only necessary to parse the Ns POs in the first PF in the group (each PF corresponds to Ns POs), so as to know the listening status and / or the acquisition status of TRS of Ns POs in the PF in a DRX cycle or multiple DRX cycles, thereby avoiding the terminal device from being awakened at a paging time when no monitoring is required, so that the terminal device can be in a dormant state for a longer time, thereby reducing power consumption; and / or the terminal device obtains the acquisition status of TRS corresponding to the PO according to the PEI, and uses TRS for auxiliary time and frequency synchronization, thereby shortening the wake-up time and saving power consumption.

[0502] To help understand the technical solution, we will take a specific PEI scenario as an example:

[0503] In the scenario where a PF includes multiple PEIs and a DRX cycle includes multiple groups, refer to Figure 7 , SearcheSpaceId=0, Ns=2, N=T / 4, T=256, then N=256 / 4=64, that is, when DRX Cycle=256 wireless frames, there are N=64 PFs in one DRX cycle, and each PF has Ns=2 POs. Then the PO in the entire DRX cycle is divided into two parts (i.e., group 1 and group 2) for PEI indication.

[0504] It should be noted that in Figure 7 In the example, the indication information of PEI can indicate the TRS of each PF in group 1 and group 2. Fig.10 For example, see Fig.10 , SearcheSpaceId=0, Ns=2, N=T / 4, T=256, then N=256 / 4=64, that is, when DRXCycle=256 wireless frames, there are N=64 PFs in a DRX Cycle, and each PF has Ns=2 POs. Then the PO in the entire DRXCycle is divided into two parts (i.e., group 1 and group 2) for PEI indication.

[0505] against Fig.10 In one embodiment, if PEI is DCI-based and the number of bits used for PEI indication is 48, then a PEI can indicate L=32 PFs. The embodiment design diagram is only used to indicate the scheduling process, and does not indicate that the scheduled PFs are scheduled in parallel, that is, PF0, PF1, ......., PF63 are arranged in chronological order. Fig.10The grouping method and PEI jump indication TRS indication method also apply to Figure 7 , Figure 8a and Figure 8b , Figure 7 , Figure 8a and Figure 8b PEI can synchronously indicate the acquisition status of TRS corresponding to PO. Fig.10 The applicability of grouping and indication methods can be found in Fig.10 Add PEI jump indication to indicate the monitoring status of at least one PO of each PF group, please refer to Fig.15 , the PEI jump indicates the monitoring status of the PO and the acquisition status of the TRS at the corresponding position of each PF in each group.

[0506] For example, refer to Figure 8a and Figure 8b , SearcheSpaceId=1, Ns=4, N=T / 2, T=256, then N=256 / 2=128, that is, when DRX cycle=256 radio frames, there are N=128 PFs in a DRX Cycle, and each PF has Ns=4 POs. Then the PO in the entire DRX Cycle is divided into four parts (group 1, group 2, group 3 and group 4) for PEI indication.

[0507] Optionally, the PEI is located before the corresponding PO in the first PF in the same group, and the at least one PF indicated by the indication information exists in the at least one group. When the terminal device is in the RRC idle or RRC INACTIVE state, during the process of the terminal device monitoring the paging message, the network device may first configure the grouping state of the PF to include the following:

[0508] (1) If there is only one group in a DRX cycle, a PEI is placed before each of the Ns PO monitoring of the first PF in a DRX cycle. The indication information of this PEI indicates whether the PO at the corresponding position of each PF in the entire DRX cycle needs to be monitored and / or whether to perform auxiliary time and frequency synchronization through TRS. If monitoring is not required, the terminal device directly skips the PO that does not need to be monitored and remains dormant. It is only awakened to perform PDCCH monitoring when the paging time that needs to be monitored is required, and / or when the PO needs to be monitored and the TRS indicated by the PEI is available, it performs auxiliary time and frequency synchronization through TRS.

[0509] (2) If multiple DRX cycles belong to the same group, a PEI is placed before each of the Ns PO monitorings of the first PF of the first DRX cycle in timing, and the indication information of this PEI indicates whether the PO at the corresponding position of each PF of the multiple DRX cycles needs to be monitored and / or whether to perform auxiliary time-frequency synchronization through TRS. If monitoring is not required, the terminal device directly skips the PO that does not need to be monitored and remains dormant. It is only awakened to perform PDCCH monitoring when the paging opportunity that needs to be monitored is required, and / or when the PO needs to be monitored and the TRS indicated by the PEI is available, it performs auxiliary time-frequency synchronization through TRS.

[0510] (3) If a DRX cycle contains multiple groups, a PEI is placed before the Ns PO monitoring of the first PF of each group. The indication information of this PEI indicates whether the PO at the corresponding position of each PF of each group needs to be monitored and / or whether to perform auxiliary time and frequency synchronization through TRS. If monitoring is not required, the terminal device directly skips the PO that does not need to be monitored and remains dormant. It is only awakened at the PO position that needs to be monitored to monitor PDCCH, and / or when the PO needs to be monitored and the TRS indicated by the PEI is available, it performs auxiliary time and frequency synchronization through TRS.

[0511] In yet another embodiment, the step A00 includes:

[0512] A PF of at least one packet in at least one DRX cycle is determined according to the first number and / or the second number.

[0513] The first number is the number of PFs included in the DRX cycle, and the second number is the number of identifiers carrying the indication information of the PEI. Based on the first number and / or the second number, determine which paging frames of the DRX cycle the PF of at least one packet in at least one DRX cycle is, such as determining the number L of PFs of a packet based on the first number and the second number.

[0514] For ease of understanding, assume that the first number is N, the second number is G, and the total number of radio frames in a DRX cycle is T. Based on the protocol relationship in Table 2, it can be seen that N, the number of PFs in a group is L, and L=2 x <=G. For the scenario where there are more than L PFs in a DRX cycle (i.e., N>L), a classification indication can be made for each L PF to form a group. The advantage of indicating only the L PFs of the entire DRX cycle is that DCI bits or reference signal sequences are saved, so that at most only L DCI bits or reference signal sequences are needed to indicate the entire DRX cycle. The value of L depends on the number of DCI bits or reference signal sequences ultimately used to carry PEI (i.e., the second number G). For example, based on L=2 x<=G, DCI-based PEI has 48 bits (ie, G=48), then L is 32; DCI-based PEI has 12 bits (ie, G=12), then L is 8.

[0515] against Figure 7 The embodiment is given assuming that the number of DCI-based PEI bits is 48 and one PEI indicates L=32 PFs. The embodiment design diagram is only used to show the scheduling process, and does not mean that the scheduled PFs are scheduled in parallel, that is, PF0, PF1, ......., PF63 are arranged in chronological order.

[0516] Optionally, the meanings of Paging related parameters are summarized according to 38.304 and 38.331 protocols, as shown in Table 5. According to possible values ​​of high-level signaling, the number of PFs that may exist in a DRX cycle is summarized in Table 6.

[0517] It can be seen from Table 6 that there may be too many PFs in a DRX cycle. In order to save DCI bits or reference signal sequences, classification is made according to the different numbers of PFs in the DRX cycle. The purpose is to use as many bits or reference signal sequences as possible to indicate the PF in the DRX cycle, so as to ensure that the terminal equipment can be in sleep state for a longer time under low paging rate, so as to reduce power consumption.

[0536] The following further details the indication situation of the indication information:

[0549] In one implementable embodiment, the indication information of PEI can instruct the terminal device: not to monitor at least one PO of different PFs in at least one group and to perform auxiliary time-frequency synchronization based on at least one TRS of different PFs in at least one group, and not to monitor at least one PO of different PFs in at least one group and to perform auxiliary time-frequency synchronization based on at least one TRS of different PFs in at least one group, that is, the monitoring status of at least one PO of different PFs in at least one group is that no monitoring is required, and the acquisition status of multiple TRS of different PFs in at least one group is that some are available and some are not available, the terminal device does not monitor at least one PO of different PFs in at least one group and indicates that at least one TRS of different PFs in at least one group is available, and does not monitor at least one PO of different PFs in at least one group and indicates that at least one TRS of different PFs in at least one group is not available.

[0550] In this embodiment, the indication information of PEI can jump to indicate: at least one PO of different PFs in one or more groups is monitored, does not need to be monitored, or partially monitors and partially does not need to be monitored, and / or, TRS is available, TRS is not available, or part of TRS is available and part is not available, and the indication information can cover the PO monitoring status and / or TRS acquisition status in one or more PFs. PEI can be located before each PO in the first PF in the same group, and provides an implementation method for PEI to jump to indicate at least one PO of different PFs, saving the number of identifiers carrying PEI (such as DCI bit or reference signal sequence), ensuring that the terminal device can be in a sleep state for a longer time under a low paging rate and / or can perform PO demodulation in a shorter time to reduce power consumption.

[0551] Optionally, the PEI includes: the monitoring status of at least one PO of at least one PF in the same or different DRX cycles and / or the acquisition status of TRS.

[0552] Optionally, the step A10 includes at least one of the following:

[0553] If the PF in the configured DRX cycle is configured as a single group, the PEI before each PO in the first PF of the single group is sent to indicate the monitoring status and / or TRS acquisition status of the PO at the corresponding position of each PF of the single group;

[0554] The network device (such as a base station) sends PEI, and the terminal device parses the indication information in the PEI before each PO in the first PF of a single group one by one. The terminal device determines the listening status and / or TRS acquisition status of the PO at the corresponding position of each PF of a single group based on the parsed indication information.

[0555] If the PF in the configured DRX cycle is configured as multiple groups, the PEI before each PO in the first PF of each group is sent to indicate the monitoring status of the PO at the corresponding position of each PF of each group and / or the acquisition status of the TRS. Optionally, the monitoring status includes monitoring, no need to monitor, or partial monitoring and partial no need to monitor, and the acquisition status can be available, unavailable, or partially available and partially unavailable.

[0556] The network device (such as a base station) sends a PEI, and the terminal device polls according to the grouped PF, parsing the indication information in the PEI before each PO in the first PF of each grouped PF one by one. The terminal device determines the monitoring status of the PO at the corresponding position of each PF in the group where the PEI is located and / or the acquisition status of the TRS based on the parsed indication information. That is, there are multiple grouped PFs in a DRX cycle, and the PEI before each PO of the first PF in each grouped PF completes the indication of whether the PO at the same position of all PFs in the group monitors the paging message and / or whether the time and frequency synchronization is performed through the TRS.

[0557] Optionally, the step A10 includes at least one of the following:

[0558] If the PF in the configured DRX cycle is configured as a single group, the indication information in the PEI before each PO in the first PF of the single group is sent, indicating the monitoring status and / or TRS acquisition status of the POs at the corresponding positions of the non-continuous multiple PFs selected by the predetermined rule of the single group;

[0559] The network device (such as a base station) sends a PEI, and the terminal device parses the indication information in the PEI before each PO in the first PF of a single group PF one by one. The terminal device determines the listening status and / or TRS acquisition status of the PO at the corresponding positions of multiple non-continuous PFs selected by a predetermined rule of the single group PF based on the parsed indication information.

[0560] If the PF within the configured DRX cycle is configured as multiple groups, the indication information in the PEI before each PO in the first PF of each group is sent, indicating the listening status and / or TRS acquisition status of the POs at the corresponding positions of multiple non-continuous PFs selected by the predetermined rules of each group.

[0561] When a network device (such as a base station) sends a PEI, the terminal device polls according to the grouped PF, and parses the indication information in the PEI before each PO in the first PF of each grouped PF one by one. The terminal device determines the listening status of the PO at the corresponding positions of multiple non-continuous PFs selected according to the predetermined rule of the grouped PF where the PEI is located and / or the acquisition status of the TRS based on the parsed indication information. That is, there are multiple grouped PFs in one DRX cycle, and the PEI before each PO of the first PF in each grouped PF completes the indication of the PO listening status of the same position of multiple non-continuous PFs in the group and / or the acquisition status of the TRS at the corresponding position of the PO.

[0562] Optionally, the predetermined rule may be to determine multiple non-continuous PFs by selecting odd or even numbers of PF sequence numbers in the group, selecting an arithmetic progression, etc., to distinguish each continuous PF in the group. The predetermined rule selects multiple non-continuous PFs that are applicable to the situations of a single group and multiple groups.

[0563] In the preset rule one feasible method, the preset rule is an odd-even selection method, that is, a PF with an odd or even number is selected in a group, the PEI before each PO before the first PF in this group is parsed, and the listening status and / or TRS acquisition status of the POs at the corresponding positions of multiple non-continuous PFs with odd or even numbers are determined.

[0564] In an optional embodiment, the preset rule is to select a plurality of non-continuous PFs with odd sequence numbers, referring to Fig.16 , a group includes 6 PFs, each PF has 2 POs, and the PFs in the group are PF0, PF1, PF2, PF3, PF4, and PF5. The PEI jumps before PO0 and PO1 in the first PF0 of this group indicate the monitoring status of the POs at the corresponding positions in PF1, PF3, and PF5 and the acquisition status of TRS. It should be noted that in this optional embodiment, only a detailed explanation of selecting non-continuous multiple PFs according to the preset rules is provided, which may include but is not limited to 6 PFs, and also includes but is not limited to 2 POs for each PF.

[0565] Optionally, the preset rule may be to select multiple non-contiguous PFs with even serial numbers, for example, a group includes 12 PFs, and the PEI jump of the first PF in the group indicates the listening status and / or TRS acquisition status of the PO at the corresponding positions of PF2, PF4, PF6, PF8, PF10 and PF12.

[0566] Optionally, the preset rule may select multiple non-contiguous PFs whose serial numbers are each value of an arithmetic sequence. For example, a group includes 12 PFs, the arithmetic sequence is a sequence with a first term of 0 and a common difference of 3, and the arithmetic sequence is 0, 3, 6, 9, 12. Therefore, the PEI jump of the first PF in the group indicates the listening status and / or TRS acquisition status of the PO at the corresponding positions of PF3, PF6, PF9 and PF12.

[0567] Optionally, the step A10 includes: sending the PEI of the corresponding PO in at least one group of PFs in at least one DRX cycle.

[0569] The process of the network device sending the PEI may include at least one of the following:

[0570] If the PF in the configured DRX cycle is configured as a single group, the indication information in the PEI before each PO in the first PF of the single group is sent, indicating the monitoring status and / or TRS acquisition status of the POs at the corresponding positions of the non-continuous multiple PFs selected by the predetermined rule of the single group;

[0571] If the PF in the configured DRX cycle is configured as multiple groups, the PEI before each PO in the first PF of each group is sent to indicate the monitoring status and / or TRS acquisition status of the PO at the corresponding position of each PF of each group;

[0572] or,

[0573] If the PF in the configured DRX cycle is configured as a single group, the indication information in the PEI before each PO in the first PF of the single group is sent, indicating the monitoring status and / or TRS acquisition status of the POs at the corresponding positions of the non-continuous multiple PFs selected by the predetermined rule of the single group;

[0574] If the PF within the configured DRX cycle is configured as multiple groups, the indication information in the PEI before each PO in the first PF of each group is sent, indicating the listening status and / or TRS acquisition status of the POs at the corresponding positions of multiple non-continuous PFs selected by the predetermined rules of each group.

[0579] Do not send paging messages during paging occasions;

[0580] No tracking reference signal is sent during paging occasions;

[0581] No paging message is sent and no tracking reference signal is sent during the paging occasion;

[0582] Sending a paging message at a paging opportunity does not send a tracking reference signal;

[0583] Sending a tracking reference signal during a paging occasion does not send a paging message.

[0584] The network device sends the PEI before the PO, and the network device also includes at least one of the following:

[0585] The network device sends a paging message at the paging opportunity so that the terminal device can monitor the PO according to the identification unit of the indication information of the PEI;

[0586] The network device sends TRS at the paging opportunity so that the terminal device can perform TRS synchronization according to the identification unit of the indication information of PEI;

[0587] The network device sends a paging message and TRS at the paging opportunity, so that the terminal device can monitor PO and perform TRS synchronization according to the identification unit of the PEI indication information;

[0588] The network device does not send a paging message at the paging opportunity, so that the terminal device does not monitor the PO according to the identification unit of the indication information of the PEI;

[0589] The network device does not send TRS at the paging time, so that the terminal device does not perform TRS synchronization according to the identification unit of the indication information of PEI;

[0590] The network device does not send a paging message and does not send a TRS at the paging opportunity, so that the terminal device does not monitor the PO and does not perform TRS synchronization according to the identification unit of the indication information of the PEI;

[0591] The network device sends a paging message without sending a TRS at the paging opportunity, so that the terminal device can monitor the PO according to the identification unit of the indication information of the PEI without performing TRS synchronization;

[0592] The network device sends TRS and does not send a paging message at the paging opportunity, so that the terminal device does not monitor PO and performs TRS synchronization according to the identification unit of the indication information of PEI.

[0593] The instructions in the PEI for configuring network devices are explained below with specific examples:

[0594] When PEI is DCI-based, multiple bits in PEI correspond to jump indications of the listening status of multiple POs at the same position of PFs, that is, if the identification unit of the indication information (such as a bit) is a first value (such as 1), then the listening status of the PO indicated by this identification unit is listening, and the PDCCH and / or PDSCH of the PO indicated by this identification unit is listened; if the identification unit of the indication information (such as a bit) is a second value (such as 0), then the listening status of the PO indicated by this identification unit is not listening, and the PDCCH and / or PDSCH of the PO indicated by this identification unit is not listened.

[0595] For example, PEI is 0101, that is, the identification unit of the indication information is 0101 in sequence, and PO1 at the same position in PF0, PF1, PF2 and PF3 is jumped and indicated in sequence. Then, the PDCCH and / or PDSCH of PO1 of PF0 is not monitored, the PDCCH and / or PDSCH of PO1 of PF1 is monitored, the PDCCH and / or PDSCH of PO1 of PF2 is not monitored, and the PDCCH and / or PDSCH of PO1 of PF3 is monitored.

[0596] Optionally, when the indication information of PEI is a reference signal sequence, the identification unit (such as a subsequence) of the reference signal sequence is a first value, then the PDCCH and / or PDSCH of the PO indicated by this identification unit is monitored; if it is a second value, then the PDCCH and / or PDSCH of the PO indicated by this identification unit is not monitored.

[0597] Based on basically the same principle, when the TRS-related indication information of PEI is a plurality of bits of DCI, the plurality of bits of the indication information correspond to the jump indication of the acquisition status of the TRS corresponding to the PO at the same position of the plurality of PFs, that is, if the identification unit (such as a bit) of the indication information is a first value (such as 1), then the acquisition status of the TRS corresponding to the PO indicated by this identification unit is obtainable, and it is determined that the TRS corresponding to the PO indicated by this identification unit is applied to the auxiliary time-frequency synchronization before PO demodulation; and / or, if the identification unit (such as a bit) of the indication information is a second value (such as 0), then the acquisition status of the TRS corresponding to the PO indicated by this identification unit is unavailable, and it is determined that the TRS corresponding to the PO indicated by this identification unit is not applied to the auxiliary time-frequency synchronization before PO demodulation.

[0598] For example, PEI is 0101, that is, the identification unit of the indication information is 0101 in sequence, and the TRS corresponding to the same position in PF0, PF1, PF2 and PF3 are jumped in sequence. Then the TRS corresponding to PO1 of PF0 is not available, the TRS corresponding to PO1 of PF1 is available, the TRS corresponding to PO1 of PF2 is not available, and the TRS corresponding to PO1 of PF3 is available.

[0599] Optionally, when the TRS-related indication information of PEI is a reference signal sequence, the identification unit (such as a subsequence) of the reference signal sequence is a first value, then the TRS corresponding to the PO indicated by this identification unit is available and can be applied to time-frequency synchronization before PO demodulation; and / or, the identification unit (such as a subsequence) of the reference signal sequence is a second value, then the TRS corresponding to the PO indicated by this identification unit is not available.

[0600] When the identification unit of PEI is used to indicate both the listening state of PO and the acquisition state of TRS, the PEI indication information is interpreted as follows (taking DCI-based PEI as an example, Sequence-based PEI has the same interpretation):

[0601] For example, PEI is 01010001, that is, the identification unit of the PO monitoring status indication information (i.e., PO indication) is 0101 in sequence, and the identification unit of the TRS acquisition status indication information (i.e., TRS acquisition indication) is 0001. PEI jumps to indicate PO1 at the same position in PF0, PF1, PF2 and PF3 in sequence. Then, PO1 of PF0 is not monitored and the TRS corresponding to PO1 of PF0 is not available, PO1 of PF1 is monitored and the TRS corresponding to PO1 of PF1 is not available, PO1 of PF2 is not monitored and the TRS corresponding to PO1 of PF2 is not available, PO1 of PF3 is monitored and the TRS corresponding to PO1 of PF3 is available and can be applied to auxiliary time and frequency synchronization before PO demodulation.

[0602] When the PF contained in the DRX cycle contains only one PO, that is, Ns=1, and the number of PFs is relatively small, such as 2, 4, 8, etc., it is only necessary to place a PEI carrying a TRS acquisition indication (that is, TRS acquisition status-related indication information) in front of at least one PO of the first PF to indicate the acquisition status of TRS within the entire DRX cycle.

[0603] When the acquisition indication of TRS corresponding to each PO is random, and each PF in the DRX cycle contains at least one PO, and the number of PFs in the DRX cycle is relatively large, for example, there are 128 PFs in each DRX cycle, it is necessary to group the PFs in the entire DRX cycle according to the bits that PEI can represent, and place PEI only in front of each PO in the first PF of each group to indicate the acquisition status of TRS of the entire group.

[0604] The PEI in this application can be used to indicate only the monitoring state of the PO, or only the acquisition state of the TRS corresponding to the PO, or both the monitoring state of the PO and the acquisition state of the TRS corresponding to the PO. Fig.11a and Fig.11b, a technical solution is given for PEI to indicate both PO listening status and TRS acquisition status at the same time, and the example is DCI-based, and the design of Sequence-based PEI has the same technical solution. In one embodiment of the technical solution, the above embodiments and Figures 5 to 10 An example is given, which shows that PEI only indicates the PO listening state or PEI only indicates the TRS acquisition state of PO. In fact, PEI can also be used to indicate both the PO listening state and the TRS acquisition state, such as Figures 14 to 16 Example.

[0605] The purpose of TRS acquisition indication is to enable the terminal device to know in advance whether TRS exists, so as to assist SSB in achieving better downlink synchronization when PO demodulation is required, thereby ensuring the success rate of PO demodulation. Based on this, this patent also proposes that whether TRS acquisition indication is required can be determined according to whether PO needs to be monitored in PEI. That is, if the bit indicating the PO monitoring status in PEI is 0, that is, there is no need to monitor PO, then the TRS acquisition indication does not need to occupy bits, and a reserved bit can be preset instead, which can further save PEI indication bits. The design scheme is also applicable to SSS-based or TRS-based PEI.

[0606] Reference Fig.11a , assuming that the PO indication bit in the PEI indication: 0 means that this PO does not need to be monitored, 1 means that this PO needs to be monitored; the TRS availability indication in the PEI: 0 bit means that TRS is not available, 1 means that TRS is available, and the reserved bit means that the current bit does not need to be occupied temporarily. Fig.11b The TRS acquisition indication given in the PEI is valid only when the PO needs to monitor, and Fig.11b The bit design is that one PO indication corresponds to one TRS availability indication, but only when the PO indication bit is 1, the TRS availability indication needs to be parsed for availability and unavailability.
