Description

Technical Field

[0001] This disclosure relates to the field of communications, and in particular to a power-saving method, apparatus, device, and readable storage medium. Background Technology

[0002] In IDLE / INACTIVE mode, the network uses a paging mechanism to locate the UE. When the network has downlink data or signaling that needs to be sent, it sends a paging message to prompt the UE to initiate an RRC connection establishment or connection recovery process, thus returning it to the RRC connected state.

[0003] For the paging mechanism, the UE uses Discontinuous Reception (DRX) in IDLE / INACTIVE state to listen for paging, and listens for a paging occupancy (PO) in each DRX cycle. The PO contains multiple PDCCH listening occupancy opportunities. In related technologies, Paging Early Indication (PEI) is introduced to determine in advance whether a paging message has been sent and to indicate whether the UE needs to perform the paging process.

[0004] However, there is currently no indication method for PEI in multi-beam scenarios. Summary of the Invention

[0041] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0042] Figure 1 A block diagram of a communication system provided in an illustrative embodiment of the present disclosure is shown. The communication system may include: a core network 11, an access network 12, and a terminal 13.

[0043] The core network 11 includes several core network devices 110. These core network devices 110 include Access and Mobility Management Function (AMF), Session Management Function (SMF), and User Plane Function (UPF), among others. The AMF controls terminal access permissions and handover functions, while the SMF provides server continuity and uninterrupted user experience, such as handling changes in Internet Protocol (IP) addresses and anchor points.

[0044] Access network 12 includes several access network devices 120. Each access network device 120 can be a base station, which is a device deployed in the access network to provide wireless communication functions for terminals. Base stations can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the names of devices with base station functions may differ. For example, in Long Term Evolution (LTE) systems, they are called eNodeB or eNB; in 5G New Radio (NR) systems, they are called gNodeB or gNB. As communication technologies evolve, the term "base station" may change. For convenience in this embodiment, the aforementioned devices providing wireless communication functions for terminals are collectively referred to as access network devices.

[0045] Terminal 13 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of User Equipment (UE), Mobile Station (MS), terminal device, etc. For ease of description, the devices mentioned above are collectively referred to as terminals. Access network device 120 and terminal 13 communicate with each other via some air interface technology, such as the Uu interface. 5G-based industrial sensors, video surveillance cameras, and wearable devices do not require such a large bandwidth, especially industrial sensors, which only require a few megabits of transmission bandwidth. Such terminals may be classified as a new terminal type in subsequent 5G enhancements and undergo corresponding technical feature improvements.

[0046] Optionally, during the wireless communication between the aforementioned terminal 13 and the access network device 120, wireless communication can be conducted via licensed frequency bands or unlicensed frequency bands.

[0047] In idle state, the terminal needs to perform paging detection according to the paging timing cycle.

[0048] In IDLE / INACTIVE mode, the network uses a paging mechanism to locate the UE. When the network has downlink data or signaling that needs to be transmitted, it sends a paging message to instruct the UE to initiate a Radio Resource Control (RRC) connection establishment or connection restoration process, thus returning it to the RRC connected state. In addition, paging can also send short paging messages to notify UEs in all states within network coverage to receive system message updates and to provide other warning information.

[0049] For the paging mechanism, the UE uses DRX in IDLE / INACTIVE state to listen for paging and listens for a paging occasion (PO) in each DRX cycle. The PO contains multiple monitoring occasions of the Physical Downlink Control Channel (PDCCH), which can contain multiple time slots or symbols. These PDCCH monitoring occasions can be used to send paging control messages (paging DCI), where the paging DCI is used to instruct the UE to decode the corresponding Physical Downlink Shared Channel (PDSCH) to obtain the paging message.

[0050] In multi-beam scenarios, paging DCI needs to be repeatedly transmitted on multiple PDCCH monitoring occasions within the same PO. This can be understood as each PDCCH monitoring occasion corresponding to a specific transmitting beam. The UE, based on its own implementation, selects one of the receivable beams to receive the paging DCI.

[0051] This is illustrative; please refer to it. Figure 2 It illustrates the current pattern of paging and listening timing in the time domain, such as... Figure 2 As shown, a paging opportunity 200 includes 12 downlink listening opportunities. The 12 downlink listening opportunities are determined by the number of synchronization signal and PBCH block (SSB) beams 4 and the number of SSB repetitions 3. The four beams periodically transmit SSBs in sequence.

[0052] In a paging system, each paging frame (PF) may contain multiple point-of-sale (POs). The PDCCH listening time of each PO needs to be mapped to the paging search space configured by the network according to parameters. These parameters indicate the starting position of the first PDCCH listening time of each PO in the paging search space. If this parameter is not configured, the starting position of the i-th PO is equal to the i×S×X-th paging search space position. S is the number of beams, and X is the number of SSB repetitions.

[0053] Although the UE needs to listen for paging messages to a PO in each DRX cycle, it does not mean that there will be paging messages sent by the network in each DRX cycle, which may cause unnecessary paging listening for the UE.

[0054] To enhance power efficiency in the paging mechanism, NR Release 17 considers introducing Paging Early Indication (PEI). PEI will determine in advance whether a paging message is due and instruct the UE whether to initiate a paging process. If no paging message is indicated, the UE will not listen for PDCCH monitoring occasions on the PO, thus saving power. (Illustrative example follows.) Figure 3 As shown, when a PEI indicating no paging is received in the DRX cycle, the listening for the PO is skipped. When a PEI indicating paging is received in the DRX cycle, the PO is listened to, and data is transmitted in the PDSCH300 according to the PO listening result.

[0055] The communication systems and service scenarios described in this disclosure are intended to more clearly illustrate the technical solutions of this disclosure and do not constitute a limitation on the technical solutions provided in this disclosure. As those skilled in the art will know, with the evolution of communication systems and the emergence of new service scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0056] Figure 4 This is a flowchart of a power-saving method provided in an exemplary embodiment of this disclosure. The method is illustrated using an application to a terminal as an example. Figure 4 As shown, the method includes:

[0057] Step 401: Receive paging advance instruction, which includes a set of downlink listening opportunities.

[0058] The search space corresponding to the downlink listening opportunity in the paging advance indication (PEI) is associated with the paging search space of the paging opportunity corresponding to the paging indication, wherein a set of downlink listening opportunities corresponds to at least two transmission beams.

[0059] Optionally, the paging advance indication includes a first number of downlink listening opportunities, which is determined by the number of SSB transmission beams and the number of repeated transmissions.

[0060] Optionally, the PEI signal is a set of PDCCH Monitoring Occasions (PMOs). Optionally, the PEI search space is associated with the paging search space of the corresponding PO.

[0061] Optionally, a PEI signal includes S×X consecutive PMOs, where S represents the number of SSB transmission beams transmitted in the current cell, and X represents the number of repetitions for each SSB transmission beam. The number of repetitions for each SSB transmission beam can be pre-configured; or it can be predefined; or it can be a default value. Optionally, when the number of repetitions for each SSB transmission beam is not pre-configured or predefined, the default value for the beam repetition count is used, such as 1.

[0062] The downlink monitoring timing is periodically arranged in the paging advance indication according to the periodic broadcast sequence of the transmission beam.

[0063] This is illustrative; please refer to it. Figure 5 In NR, a beam scanning mechanism is used to periodically broadcast SSB messages, meaning signals are sent to different beam directions within cell 500 at different times. SSB messages help the UE complete the synchronization process, enabling it to correctly receive signals sent by the base station and obtain initial access information for cell 500. When the UE receives PEI and PO signals, it can only receive the signal at the PDCCH time corresponding to that beam.

[0064] In S×X consecutive PMOs, the x×S+Kth PMO corresponds to the transmission beam of the Kth SSB, where x=0,1,…,X-1, indicating the number of repeated transmissions as X, that is, x refers to the xth repeated transmission, K=1,2,…, and S represents the transmission beams of S SSBs.

[0065] In some embodiments, the PEI search space is pre-configured, or the PEI search space is predefined, or the PEI search space is the default space of the corresponding paging search space.

[0066] In this embodiment, the PEI search space is determined by configuration as an example. That is, the terminal receives configuration information, which is used to indicate the association between the search space corresponding to the downlink listening time and the paging search space.

[0067] In some embodiments, the configuration information includes a first indication field, which is used to indicate the bias value between the search space corresponding to the downlink listening time and the paging search space; or, the configuration information includes a second indication field, which is used to indicate the search space identifier corresponding to the downlink listening time, and the search space identifier corresponds to the paging search space.

[0068] That is, the network allocates a search space for the PEI, and the allocated search space is associated with the paging search space corresponding to the PEI. The forms include the following: 1. By setting an offset value, the PEI search space is ahead of the paging search space by an offset value; 2. A dedicated PEI search space identifier is allocated to the paging search space, and the PEI signal corresponding to the PEI search space is used to respond to the PO in the paging search space.

[0069] The resources in the PEI search space are used to carry the PDCCH listening time transmission of PEI.

[0070] In some embodiments, when there is an i-th downlink listening opportunity that overlaps with uplink resources in a set of downlink listening opportunities, the i-th downlink listening opportunity that overlaps with uplink resources is extended to the (i+1)-th search space, where i≥0 and i is an integer.

[0071] That is, if the search space position of a PMO in the PEI overlaps with the uplink symbol, then the PMO is carried over to the next PEI search space position.

[0072] Optionally, the downlink listening timing corresponds to at least two retransmissions for each transmission beam.

[0073] Step 402: Listen for paging timing based on paging advance indication.

[0074] In some embodiments, the terminal implements the selection of a downlink listening time from a set of downlink listening times for paging instruction listening.

[0075] In some embodiments, since the network indicates the PMO to the terminal without knowing the receiving beam corresponding to the terminal, the PMO content indicated for multiple beams is the same. Therefore, when the terminal detects the paging indication signal at any downlink listening opportunity, it stops listening to subsequent downlink listening opportunities for the same PEI.

[0076] Optionally, when a downlink listening opportunity indicates that a paging event is being sent, the paging message is received from the paging opportunity corresponding to the downlink listening opportunity; or, when the downlink listening opportunity does not indicate that a paging event is being sent, the listening to the paging opportunity corresponding to the downlink listening opportunity is skipped.

[0077] Optionally, based on the transmission beam corresponding to the downlink listening time, the listening position of the transmission beam corresponding to the paging time is monitored, and the paging message is received.

[0078] As an illustration, when the number of beam retransmissions is greater than 1, if the UE detects the PEI signal, it is not necessary to monitor subsequent PMOs within that PEI.

[0079] The UE can listen for paging indications at any PMO in the PEI signal. When the UE receives a paging indication at any PMO in the PEI signal, it will respond to the corresponding PO of that PMO, i.e., listen to or not listen to that PO. After receiving the PMO signal, the UE will listen to the PO listening position corresponding to the SSB beam of that PMO signal.

[0080] To illustrate, if the SSB (Supports in Burst) set broadcast by the current network in the system information is configured as 4, meaning there are 4 beam transmission directions, and the number of repetitions for each SSB beam direction is configured as 2, then the PEI signal contains 8 PMOs, which correspond to the following in the PEI search space: Figure 6 As shown. Among them, as Figure 6 As shown, in a PEI signal 600, the PMOs are arranged sequentially according to the corresponding SSB beam directions. That is, the x×4+Kth PMO corresponds to the beam direction of the Kth SSB. For example, if x=0 represents the first repeated transmission of the SSB beam and K=3 represents the 3rd SSB beam, then the 0×4+3=3rd PMO corresponds to the beam direction of the 3rd SSB during the first repeated transmission of the SSB beam; if x=1 represents the second repeated transmission of the SSB beam and K=1 represents the 1st SSB beam, then the 1×4+1=5th PMO corresponds to the beam direction of the 1st SSB.

[0081] If the PEI search space is occupied by uplink resources, meaning the current position is at an uplink symbol, then the current PMO of the PEI is carried over to the next PEI search space. (For illustration purposes, please refer to...) Figure 7 ,like Figure 7 As shown, PMO#0, PMO#1, PMO#2, and PMO#3 are arranged in sequence. Among them, PMO#1 overlaps with the uplink resource, so PMO#1, PMO#2, and PMO#3 are sequentially extended one PEI search space.

[0082] When the number of repeated transmissions for each SSB beam is greater than 1, if the UE selects to monitor the PEI on PMO#1 and PMO#2 based on the implementation, as long as the PEI signal is detected on either PMO, the monitoring of all subsequent PMOs within that PEI will be stopped.

[0083] Indicative, such as Figure 8 As shown, for PEI signal 800, the UE selects to listen to PEI on PMO#1 and PMO#2, and detects a paging indication on PMO#2, so it enters sleep mode in advance and stops listening to subsequent PMOs.

[0084] Upon receiving a paging instruction, if it indicates that a paging event is currently occurring on the network, the UE will initiate a paging process at the PO corresponding to the PEI and receive the paging message; otherwise (if the network does not indicate that a paging event is occurring), it will not listen to the PO.

[0085] After the UE receives a paging instruction from the PMO of a certain PEI, it can listen to the listening position of the corresponding SSB beam in the PO according to the SSB beam of that PMO.

[0086] like Figure 9 As shown, when PMO#1 in PEI receives a paging instruction, corresponding to the first SSB beam, it will listen for paging messages at the position corresponding to the first beam in PO.

[0087] In summary, the power-saving method provided in this disclosure is designed for scenarios where PEI is introduced into the NR system and multiple beams need to be considered. Therefore, the PEI monitoring mode is designed to ensure that the UE can correctly monitor the PEI signal.

[0088] Figure 10 This is a flowchart of a power-saving method provided in an exemplary embodiment of the present disclosure. The method is illustrated using an example of its application in a communication system including a terminal and network devices. Figure 10 As shown, the method includes:

[0089] Step 1001: The network device periodically broadcasts a paging advance indication via at least two transmission beams, the paging advance indication including a downlink listening opportunity.

[0090] The search space corresponding to the downlink listening timing in the paging advance indication (PEI) is associated with the paging search space of the paging timing corresponding to the paging indication. The method by which network devices broadcast the paging advance indication is as described above. Figure 5 As shown.

[0091] Step 1002: The terminal receives a paging advance instruction, which includes a set of downlink monitoring opportunities.

[0092] One set of downlink monitoring times corresponds to at least two transmission beams.

[0093] Optionally, the paging advance indication includes a first number of downlink listening opportunities, the first number being determined by the number of transmission beams and the number of repeated transmissions.

[0094] Optionally, the PEI search space is associated with the paging search space of the corresponding PO.

[0095] Optionally, a PEI signal includes S×X consecutive PMOs, the x×S+Kth PMO corresponds to the Kth SSB beam direction, where x=0,1,…,X-1, indicating that there are X beam repetitions, K=1,2,…,S represents S S SSB beam directions.

[0096] In some embodiments, the PEI search space is pre-configured, or the PEI search space is predefined, or the PEI search space is the default space of the corresponding paging search space.

[0097] That is, the network allocates a search space for the PEI, and the allocated search space is associated with the paging search space corresponding to the PEI. The forms include the following: 1. By setting an offset value, the PEI search space is ahead of the paging search space by an offset value; 2. A dedicated PEI search space identifier is allocated to the paging search space, and the PEI signal corresponding to the PEI search space is used to respond to the PO in the paging search space.

[0098] In some embodiments, when there is an i-th downlink listening opportunity that overlaps with uplink resources in a set of downlink listening opportunities, the i-th downlink listening opportunity that overlaps with uplink resources is extended to the (i+1)-th search space, where i ≥ 0 and i is an integer.

[0099] Optionally, the downlink listening timing corresponds to at least two retransmissions for each transmission beam.

[0100] Step 1003: The terminal listens for the paging timing based on the paging advance instruction.

[0101] In some embodiments, the terminal implements the selection of a downlink listening time from a set of downlink listening times for paging instruction listening.

[0102] In some embodiments, since the network indicates the PMO to the terminal without knowing the receiving beam corresponding to the terminal, the PMO content indicated for multiple beams is the same. Therefore, when the terminal detects the paging indication signal at any downlink listening opportunity, it stops listening to subsequent downlink listening opportunities for the same PEI.

[0103] Optionally, when a downlink listening opportunity indicates that a paging event is being sent, the paging message is received from the paging opportunity corresponding to the downlink listening opportunity; or, when the downlink listening opportunity does not indicate that a paging event is being sent, the listening to the paging opportunity corresponding to the downlink listening opportunity is skipped.

[0104] Optionally, based on the transmission beam corresponding to the downlink listening time, the listening position of the transmission beam corresponding to the paging time is monitored, and the paging message is received.

[0105] In summary, the power-saving method provided in this disclosure is designed for scenarios where PEI is introduced into the NR system and multiple beams need to be considered. Therefore, the PEI monitoring mode is designed to ensure that the UE can correctly monitor the PEI signal.
