Description

Method executed by user equipment and user equipment Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and more particularly, to a method for executing restricted paging by a user equipment and corresponding user equipment. Background Art

[0002] Network energy saving helps reduce environmental impact and save operator costs. By lengthening the time interval for the base station to continuously receive and send data and shutting down the transmission and reception of some symbols, the base station can be put into sleep mode, or the cell where it is located can be put into network energy saving mode, thereby reducing the power consumption of the base station and achieving network energy saving. For the above reasons, in December 2022, at the 3rd Generation Partnership Project (3GPP) RAN#98e plenary meeting, the NR network energy saving work item for version 18 (see non-patent document: RP-223540 New WID: Network energy savings for NR) was approved. One of the goals of this work item is to enhance restricted paging, that is, to reduce the power consumption caused by network paging UE, so as to achieve the purpose of network energy saving.

[0003] The present invention discusses how the UE monitors / receives paging-related messages and / or indications after the introduction of restricted paging, and how the UE reports restricted paging-related auxiliary information to the network.

[0004] Summary of the Invention

[0005] The present invention provides a method executed by a user equipment and the user equipment, for solving the problem of how the UE monitors / receives paging-related messages and / or indications after the introduction of restricted paging, and how the UE reports restricted paging-related auxiliary information to the network.

[0006] According to one aspect of the present invention, a method performed by a user equipment is provided, comprising the following steps: the user equipment receiving restricted paging configuration information sent by a network; and the user equipment receiving paging in a corresponding manner according to configuration information included in the received restricted paging configuration information.

[0007] In the above-mentioned method performed by the user equipment, preferably, the configuration information contained in the restricted paging configuration information includes at least one of restricted paging indication, PEI restricted transmission indication, restricted paging beam information, restricted paging effective time information, and restricted paging quality threshold information.

[0008] In the above-mentioned method performed by the user equipment, it is preferred that, when the restricted paging configuration information received by the user equipment includes the restricted paging indication, the user equipment receives paging in a restricted manner; when the restricted paging configuration information received by the user equipment includes the restricted paging beam information, the user equipment receives paging on the beam indicated by the restricted paging beam information; when the restricted paging configuration information received by the user equipment includes the restricted paging valid time information, the user equipment receives paging in a restricted manner within the restricted paging valid time indicated by the restricted paging valid time information; when the restricted paging configuration information received by the user equipment includes the restricted paging quality threshold information, the user equipment selects a beam that meets the restricted paging quality threshold configured by the restricted paging quality threshold information as the beam for receiving restricted paging; when the restricted paging configuration information received by the user equipment includes the PEI restricted transmission indication, the user equipment receives PEI in a restricted manner.

[0009] In the above method executed by the user equipment, preferably, the network does not configure eDRX and the restricted paging configuration information at the same time.

[0010] According to one aspect of the present invention, a method performed by a user equipment is provided, comprising the following steps: the user equipment receives a UE reporting restricted paging assistance information indication sent by a network; when the user equipment meets a given condition, the user equipment initiates a process of reporting restricted paging assistance information to the network; and the user equipment sets the message content in an RRC message carrying the restricted paging assistance information.

[0011] In the above-mentioned method performed by the user equipment, preferably, the given condition is at least one of the following conditions: the user equipment is configured to report the restricted paging assistance information to the network; the user equipment has an expected paging strategy; since the user equipment was configured to report the restricted paging assistance information to the network, the user equipment has not sent a message with the restricted paging assistance information to the network; and the current restricted paging assistance information of the user equipment is different from the restricted paging assistance information in the message with the restricted paging assistance information sent last time.

[0012] In the above-mentioned method performed by the user equipment, it is preferred that, in the step of the user equipment setting the message content in the RRC message carrying the restricted paging assistance information, the user equipment causes the RRC message to include the expected paging policy information or the expected paging policy information of the current cell group when at least one of the following conditions is met: the transmission of the RRC message is initiated due to the provision of the restricted paging assistance information; the user equipment has the expected paging policy; and the user equipment has the expected paging policy of the current cell group.

[0013] In the above method performed by the user equipment, preferably, when the user equipment is performing eDRX, the user equipment selects the beam for receiving paging on its own, and when the user equipment is not performing eDRX, the user equipment receives paging in a restricted manner.

[0014] According to another aspect of the present invention, a user equipment is provided, comprising: a processor; and a memory storing instructions; wherein the instructions, when executed by the processor, execute the method performed by the user equipment according to any one of claims 1 to 8.

[0015] The method executed by a user equipment and the user equipment according to the present invention can solve the problem of how the UE monitors / receives paging-related messages and / or indications after the introduction of restricted paging, and how the UE reports restricted paging-related auxiliary information to the network.

[0071] Hereinafter, a description is given of related technologies of the present invention.

[0072] Paging and DRX

[0073] When the UE is in RRC_IDLE and RRC_INACTIVE, since there is no RRC connection between the UE and the network, if the network has downlink data to send to the UE, it needs to page the UE first, that is, send a paging message to the UE. After receiving the paging message, the UE triggers the establishment of an RRC connection as a paging response, or sends a paging response message to the network after establishing the RRC connection. After receiving the paging response from the UE, the network transmits the downlink data to the UE.

[0074] To reduce the need to monitor and receive paging messages, UEs in the RRC_IDLE and RRC_INACTIVE states typically use DRX (discontinuous reception) to monitor / receive paging messages. The UE monitors a paging event (PO) during each DRX cycle. A PO is a set of PDCCH monitoring times, which can include multiple time slots. The network can send paging DCI messages to the UE in the PO. A PF is a radio frame that can include one or more POs or a PO starting point. The UE first determines the PF based on the DRX cycle and then the PO based on the PF. After monitoring the paging DCI during the PO, the UE receives the paging message at the radio resource time-frequency location indicated by the DCI. For example, the terminal determines the paging event location within each DRX cycle based on network-configured parameters, detects the paging PDCCH at the paging PDCCH detection time associated with the paging event, and takes further action based on the information indicated in the paging PDCCH. The terminal can obtain the UE_ID parameter used to determine the paging event based on identifiers such as the terminal's TMSI or IMSI.

[0075] In a multi-beam scenario, the UE assumes that the same paging message is repeated on all transmitted beams. In other words, the UE assumes that the network sends paging messages on all beams. The UE selects which beam or beams to receive the paging message on is left to the UE. When the UE is in the RRC_IDLE / RRC_INACTIVE state, the beam it monitors is generally the SSB.

[0076] eDRX

[0077] To further reduce power consumption, eDRX (extended discontinuous reception) was introduced. eDRX can be used in both RRC_IDLE and RRC_INACTIVE modes. The eDRX cycle can be longer than the DRX cycle, further reducing power consumption.

[0078] PEI

[0079] To save power consumption, terminals in RRC_IDLE and RRC_INACTIVE states usually operate in DRX state. When not receiving data, the terminal enters sleep state. There may be time and frequency deviations between the terminal and the base station during operation. Especially in sleep state, the continuous accumulation of small deviations may become larger deviations. When receiving data, the terminal needs to meet the time and frequency synchronization status with the base station to ensure the correct transmission of data. The terminal can perform time and frequency tracking by receiving SSB to obtain more accurate synchronization with the base station. Therefore, when performing PO detection to receive PDCCH, the terminal needs to wake up in advance and receive multiple SSBs to achieve time and frequency synchronization between the terminal and the network. If the DCI detected by the terminal in PO indicates that no paging data is received, the terminal can re-enter sleep mode to save power consumption.

[0080] The network may send an indication message before the PO detected by the terminal, indicating whether the terminal needs to detect the corresponding PO within one or more paging cycles. This indication message may be called PEI (paging early indication), or other names may be used. PEI may be used to refer to the relevant information in the following text. For example, when there is paging information in the network that needs to be received by the terminal, the network sends PEI indication information, which is used to indicate that the terminal needs to detect the PO corresponding to the indication information. The terminal wakes up before the PO, performs time-frequency synchronization, and detects the paging PDCCH and possible PDSCH reception on the determined PO. If the indication message received by the terminal indicates that the terminal does not need to detect the PO corresponding to the indication information, the terminal does not need to detect on the corresponding PO, and does not need to wake up and receive SSB before the PO for time-frequency synchronization to prepare for possible PDSCH reception. In this way, the terminal can avoid unnecessary wake-up and synchronization actions through the instructions of the network, thereby saving the power consumption of the terminal.

[0081] PEI can contain the paging subgroup information of the UE. After receiving the PEI, the UE can know whether the paging subgroup it is in will be paged. If it will not be paged, it does not need to monitor the PO indicated by the PEI, thereby avoiding receiving unnecessary paging DCI and paging messages. If the paging subgroup to which the UE belongs indicates that it has been paged in the PEI, the UE needs to monitor the PO indicated by the PEI. One PEI can be associated with multiple POs, and one PEI can also be associated with multiple PFs. The time position of the PEI can be determined by the UE's own PF calculated based on eDRX and / or DRX or its own PO minus a time offset.

[0082] Restricted Paging

[0083] To achieve energy conservation, the network can employ restricted paging for some UEs (e.g., stationary UEs or UEs with low mobility). This means that when the network needs to page these UEs, the paging message is transmitted on only some beams, rather than all beams. By reducing the beams used for paging message transmission, network energy is saved.

[0084] To implement this functionality, the base station can indicate to the core network the list of beams (e.g., the recommended SSB list) on which to send paging messages for a particular UE. When the UE is in the RRC_IDLE state and the core network has data to send to the UE, the core network will include the beam list when sending a CN paging message to the base station. The base station sends the CN paging message to the UE based on the beam list, meaning that the CN paging message can be transmitted only on the beams included in the beam list. If the UE is in the RRC_INACTIVE state and the base station initiates RAN paging, the base station can select the beam or beams on which the RAN paging message needs to be transmitted.

[0085] To enable the base station to determine the beam on which to send paging messages, the UE can report some auxiliary information to the base station, such as the UE's desired paging transmission beam, the UE's mobility status, and beam switching information. The base station can also use some configuration information to let the UE know some information about restricted paging, such as whether restricted paging will be used for the UE and which beam or beams the paging message will be transmitted on.

[0086] In the present invention, the function of transmitting a paging message (or paging-related indication) only on some (one or more) beams (in a cell) but not all (transmission) beams, or the function of transmitting a paging message only on some (one or more) beams (in a cell) but not all (transmission) beams, may be referred to as "restricted paging" or other names. The UE assuming that paging is transmitted only on some (one or more) beams (in a cell) but not all (transmission) beams, or the UE receiving paging only on some (one or more) beams (in a cell) but not all (transmission) beams, may be referred to as "receiving paging in a restricted manner" or other names.

[0087] With the introduction of restricted paging, if the beam used by the UE to receive paging messages is inconsistent with the beam used by the network to send paging messages, paging failure may occur. The network may retransmit the paging message, resulting in increased paging delay, which may affect the UE's service experience. This invention discusses how the UE monitors / receives paging-related messages and / or indications, and how the UE reports auxiliary information related to restricted paging to the network, so that the network and UE have a consistent understanding of received paging, thereby reducing possible paging failures and paging delays.

[0088] Hereinafter, several embodiments of the present invention for solving the above problems are described in detail.

[0089] In the present invention, "paging UE" may refer to sending a paging message and / or PEI to the UE, and "sending paging" may refer to sending a paging message and / or PEI; "receiving paging" may refer to receiving a paging message and / or PEI, or may refer to monitoring PO and / or PEI-O, or may refer to monitoring PO and / or PEI-O and receiving a paging message and / or PEI.

[0090] Example 1

[0091] Optionally, in step 101, the user equipment UE receives restricted paging configuration information sent by the network.

[0092] Optionally, the restricted paging configuration information may be included in a system message, an RRC-specific message (e.g., an RRC reconfiguration message, an RRC release message), a MAC CE, or a physical layer indication (e.g., a DCI). Optionally, the configuration information included in the restricted paging configuration information may include, but is not limited to, at least one of the following:

[0093] -Restricted paging indication;

[0094] -PEI restricted transfer indication;

[0095] -Restricted paging beam information;

[0096] -Restricted paging effective time information;

[0097] -Restricted paging quality threshold information;

[0098] Optionally, "restricted paging indication" can be used to indicate whether restricted paging will be performed on the UE; "restricted paging beam information" is used to indicate on which beam or beams (eg, a list of beams) the restricted paging is transmitted.

[0099] Among them, optionally, the "PEI restricted transmission indication" is used to indicate whether restricted paging will be performed on the PEI of the UE (or the PEI associated with the UE), or to indicate whether the PEI of the UE (or the PEI associated with the UE) will be transmitted only on part of the beam.

[0100] Optionally, the "restricted paging valid time information" may be used to indicate at least one of the following information:

[0101] -The network will page the UE using restricted paging during the specified time;

[0102] - The network will page the UE on the restricted paging beam(s) within the specified time;

[0103] -Within the time, the UE only needs to receive paging in some beams (for example, the beam configured by the restricted paging beam information).

[0104] Optionally, the "restricted paging validity period information" may be an absolute time or a relative time. If the "restricted paging validity period information" is a relative time, the validity period refers to the time calculated relative to when the UE receives the restricted paging validity period information.

[0105] Optionally, the “restricted paging quality threshold information” may be used to indicate at least one of the following information:

[0106] -Quality (RSRP / RSRQ) threshold and / or number of beams used by the UE to receive paging in a restricted manner;

[0107] -Quality (RSRP / RSRQ) threshold and / or number of beams based on which the UE selects the beam to receive paging.

[0108] Optionally, in step 103, the user equipment UE receives paging in a corresponding manner according to the configuration information included in the restricted paging configuration information received from the network. Specifically, the corresponding manner adopted by the UE is as follows.

[0109] Optionally, when the restricted paging configuration information received by the UE includes a restricted paging indication (optionally, and the restricted paging indication is set to: for example, TRUE or setup), the UE (after entering the RRC_INACTIVE / RRC_IDLE state) receives paging in a restricted manner, that is, receives paging on (or only on) part of the beams.

[0110] Optionally, when the restricted paging configuration information received by the UE includes restricted paging beam information, the UE (after entering the RRC_INACTIVE / RRC_IDLE state) receives paging on (or only on) the beam indicated by the restricted paging beam information.

[0111] Optionally, when the restricted paging configuration information received by the UE includes restricted paging validity period information, the UE (after entering the RRC_INACTIVE / RRC_IDLE state) receives paging in a restricted manner within (or only within) the restricted paging validity period indicated by the restricted paging validity period information. When the restricted paging validity period expires, or the UE is outside the restricted paging validity period, the UE may assume that the base station will send paging on all transmission beams, and the UE may select the beam to receive the paging.

[0112] Optionally, when the restricted paging configuration information received by the UE includes restricted paging quality threshold information, the UE (after entering the RRC_INACTIVE / RRC_IDLE state) selects a beam that meets the restricted paging quality threshold configured in the restricted paging quality threshold information as the beam for receiving (restricted) paging, that is, the RSRP / RSRQ of the beam used to receive (restricted) paging is greater than (or greater than or equal to) the RSRP / RSRQ threshold value configured by the restricted paging quality threshold information, and / or the number of beams selected for receiving (restricted) paging is equal to (or less than) the number of beams configured by the restricted paging quality threshold information.

[0113] Optionally, when the restricted paging configuration information received by the UE includes a PEI restricted transmission indication (optionally, and the PEI restricted transmission indication is set to: for example, TRUE or setup), the UE (after entering the RRC_INACTIVE / RRC_IDLE state) receives PEI in a restricted manner, that is, monitors PEI-O and / or receives PEI on (or only on) part of the beams.

[0114] Among them, optionally, the partial beams can be beams indicated by the network through restricted paging beam information, or can be beams selected by the UE for receiving restricted paging according to restricted paging quality threshold information configured by the network.

[0115] Example 2

[0116] Optionally, in step 201, the user equipment (UE) receives a UE reporting restricted paging assistance information indication sent by the network. Optionally, the "UE reporting restricted paging assistance information indication" is used to indicate whether the UE needs to report restricted paging assistance information, and may include, but is not limited to: reporting the UE's desired paging policy. The UE's desired paging policy may include, but is not limited to: normal paging, restricted paging, normally transmitted PEI, and restricted transmitted PEI.

[0117] Optionally, the configuration of the UE reporting the restricted paging assistance information indication may be implemented by including the restricted paging assistance information indication in a system message, an RRC-specific message (eg, an RRC reconfiguration message), a MAC CE, or a physical layer indication (eg, a DCI).

[0118] Optionally, when the message, MAC CE or physical layer indication includes a UE reporting restricted paging assistance information indication (and the UE reporting restricted paging assistance information indication is set to: for example, TRUE or setup), the UE considers itself to be configured to report restricted paging assistance information to the network (for example, the paging policy expected by the UE).

[0119] Optionally, in step 203, when the user equipment UE meets at least one of the following conditions, the user equipment UE initiates a process of reporting restricted paging assistance information (e.g., the paging policy expected by the UE) to the network. The UE reports the restricted paging assistance information (e.g., the paging policy expected by the UE) by including the restricted paging assistance information in an RRC message (e.g., UE assistance information UEAssistanceInformation):

[0120] -The UE is configured to report restricted paging assistance information to the network;

[0121] - The UE has a desired paging policy (wherein, as described above, the paging policy desired by the UE may include but is not limited to: normal paging, restricted paging, normal transmission PEI, restricted transmission PEI);

[0122] - Since the UE was configured to report restricted paging assistance information to the network, the UE has not sent a message with restricted paging assistance information (e.g., UEAssistanceInformation) to the network;

[0123] - The restricted paging assistance information currently carried by the UE is different from the restricted paging assistance information in the last message (eg, UEAssistanceInformation) carrying the restricted paging assistance information sent.

[0124] Optionally, in step 205, the user equipment UE sets the message content in an RRC message (e.g., UEAssistanceInformation) with restricted paging assistance information. Optionally, when the UE satisfies at least one of the following conditions, the UE causes the RRC message (e.g., UEAssistanceInformation) to include the desired paging policy information (or the desired paging policy information of the cell group):

[0125] - Transmission of the RRC message is initiated due to the provision of restricted paging assistance information;

[0126] - The UE has a desired paging policy (wherein, as described above, the paging policy desired by the UE may include but is not limited to: normal paging, restricted paging, normal transmission PEI, restricted transmission PEI);

[0127] - The UE has a desired paging policy for this cell group.

[0128] Example 3

[0129] The eDRX cycle is longer than the DRX cycle. After the introduction of restricted paging, if the UE and the network have different understandings of restricted paging, the UE operating in the eDRX state may experience more paging failures and longer paging delays. Therefore, eDRX and restricted paging cannot be used at the same time. According to Examples 1 and 2, the specific implementation method may include at least one of the following:

[0130] When the UE is operating eDRX, the UE always assumes that the base station will send paging on all transmission beams. The UE can select the beam to receive the paging.

[0131] -The UE receives paging in a restricted manner unless the UE is performing eDRX;

[0132] - The network does not configure eDRX and restricted paging configuration information at the same time;

[0133] -Restricted paging configuration information will only appear when eDRX is not configured.

[0134] The eDRX may include RAN eDRX and / or CN eDRX.

[0135] The execution of eDRX may also be described as: the UE is configured with RAN eDRX by the RRC, and / or is configured with CN eDRX by an upper layer, and / or the UE is allowed to execute RAN eDRX and / or CN eDRX.

[0136] Example 4

[0137] According to Embodiment 1 and Embodiment 2, optionally, a base station (e.g., a gNB) may send an RRC message (e.g., UE radio paging information UERadioPagingInformation) to a core network (e.g., a 5GC) or to another base station, where the RRC message includes at least one of the following information:

[0138] - UE's desired paging strategy;

[0139] -Indication of whether the UE supports restricted paging;

[0140] -PEI restricted transfer indication;

[0141] -Restricted paging effective time information;

[0142] -Restricted paging quality threshold information.

[0143] The meaning of the above information is the same as that in Example 1 and Example 2.

[0144] Optionally, the RRC message may also be sent by the core network to the base station.

[0145] Example 5

[0146] Optionally, in step 501, the user equipment UE monitors PEI-O and receives PEI. Optionally, the PEI includes restricted paging configuration information.

[0147] Optionally, the restricted paging configuration may include but is not limited to at least one of the following:

[0148] -Restricted paging indication;

[0149] -Restricted paging beam information;

[0150] -Restricted paging effective time information;
