Description

Technical Field

[0001] The present invention relates to the technical field of wireless communications, and more particularly, to a method for executing restricted paging by a user equipment and a 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 a sleep state, or the cell where it is located can be put into a 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 RAN#98e plenary meeting of the 3rd Generation Partnership Project (3GPP), 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 UEs, thereby achieving 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. Summary of the invention

[0004] The present invention provides a method executed by a user equipment and the user equipment, which are used to solve the problem of how the UE monitors / receives paging-related messages and / or instructions after the introduction of restricted paging, and how the UE reports restricted paging-related auxiliary information to the network.

[0005] 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 restricted paging configuration information sent by a network; and the user equipment receives paging in a corresponding manner according to the configuration information contained in the received restricted paging configuration information.

[0006] In the above 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.

[0007] 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 effective time information, the user equipment receives paging in a restricted manner within the restricted paging effective time indicated by the restricted paging effective 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.

[0008] 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.

[0009] 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 a message content in an RRC message carrying the restricted paging assistance information.

[0010] 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 is 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 restricted paging assistance information currently in the user equipment is different from the restricted paging assistance information in the last message sent with the restricted paging assistance information.

[0011] 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.

[0012] In the above method performed by the user equipment, preferably, when the user equipment is performing eDRX, the user equipment selects a 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.

[0013] 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.

[0014] According to the method executed by the user equipment and the user equipment involved in the present invention, the problem of how the UE monitors / receives paging-related messages and / or instructions after the introduction of restricted paging and how the UE reports restricted paging-related auxiliary information to the network can be solved.

[0070] Hereinafter, a description is given of related art of the present invention.

[0071] Paging and DRX

[0072] 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 is necessary 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.

[0073] In order to reduce the monitoring and reception of paging, in the RRC_IDLE and RRC_INACTIVE states, the UE generally uses DRX (discontinuous reception) to monitor / receive paging. The UE monitors a paging time (PO) in each DRX cycle. A PO is a collection of a series of PDCCH monitoring times, which can include multiple time slots. The paging DCI can be sent to the UE by the network in the PO. A PF is a radio frame, and a PF can include one or more POs or a starting point of a PO. The UE first determines the PF according to the DRX cycle, and then determines the PO according to the PF. After the UE monitors the paging DCI in the PO, it receives the paging message at the time-frequency position of the radio resource indicated by the DCI. For example, the terminal determines the position of the paging time in each DRX cycle according to the parameters configured by the network, detects the paging PDCCH at the paging PDCCH detection time related to the paging time, and performs the next step according to the content indicated in the paging PDCCH. The terminal can obtain the parameter UE ID used to determine the paging time according to the terminal TMSI or IMSI and other identifiers.

[0074] 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 RRC_IDLE / RRC_INACTIVE state, the monitored beam generally refers to SSB.

[0075] eDRX

[0076] In order to further save power consumption, eDRX, or extended discontinuous reception, is introduced. eDRX can be used for RRC_IDLE and RRC_INACTIVE. The eDRX cycle can be longer than the DRX cycle, thereby achieving the purpose of further saving power consumption.

[0077] PEI

[0078] In order to save power consumption, terminals in RRC_IDLE and RRC_INACTIVE states usually work in DRX state, and enter sleep state when not receiving data. There may be time and frequency deviations between the terminal and the base station when the terminal is running, 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 state 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 the terminal performs PO detection to receive PDCCH, it 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.

[0079] The network may send indication information before the PO detected by the terminal, indicating whether the terminal needs to detect the corresponding PO in one or more paging cycles. This indication information 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, and the indication information 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 information 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.

[0080] 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 the reception of 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.

[0081] Restricted Paging

[0082] In order to achieve its own energy saving purpose, the network can use restricted paging for some UEs (such as stationary UEs or UEs with low mobility), that is, when the network needs to page these UEs, the paging message is only transmitted on some beams instead of all beams. Since the beams for paging message transmission are reduced, network energy can be saved.

[0083] To achieve this function, the base station can indicate to the core network the list of beams (for example, the recommended SSB list) on which the paging message for a certain UE is sent. When the UE is in the RRC_IDLE state and the core network has data to send to the UE, the core network will carry the beam list when sending a CN paging to the base station. The base station sends a CN paging message to the UE according to the beam list, that is, 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 choose which beam or beams the RAN paging message needs to be transmitted on.

[0084] In order for the base station to determine the beam to send the paging message, the UE can report some auxiliary information to the base station, such as: the paging transmission beam expected by the UE, the mobility status of the UE, and the information of beam switching. The base station can also let the UE know some information about restricted paging through some configuration information, such as: whether the restricted paging method will be used for the UE, and on which beam or beams the paging will be transmitted.

[0085] In the present invention, a paging message (or paging-related indication) transmitted only on some (one or more) beams (in a cell) but not on all (transmission) beams, or a function in which a paging message is transmitted only on some (one or more) beams (in a cell) but not on all (transmission) beams, may be referred to as "restricted paging" or other names. The UE assumes that paging is transmitted only on some (one or more) beams (in a cell) but not on all (transmission) beams, or the UE receives paging only on some (one or more) beams (in a cell) but not on all (transmission) beams, which may be referred to as "receiving paging in a restricted manner" or other names.

[0086] After the introduction of restricted paging, if the beam that the UE receives the paging is inconsistent with the beam that the network sends the paging, paging failure may occur, and the network may resend the paging, resulting in an increase in the paging delay, which may affect the UE's service experience. The present invention discusses how the UE monitors / receives paging-related messages and / or indications, and how the UE reports restricted paging-related auxiliary information to the network, so that the network and the UE have the same understanding of the received paging, thereby reducing possible paging failures and paging delays.

[0087] Hereinafter, several embodiments of the present invention for solving the above problems are described in detail.

[0088] In the present invention, "paging UE" may refer to sending a paging message and / or PEI to 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.

[0089] Example 1

[0090] Optionally, in step 101, the user equipment UE receives restricted paging configuration information sent by the network.

[0091] Optionally, the restricted paging configuration information may be included in a system message, or an RRC-specific message (e.g., an RRC reconfiguration message, an RRC release message), or 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:

[0092] -Restricted paging indication;

[0093] -PEI restricted transfer indication;

[0094] -Restricted paging beam information;

[0095] -Restricted paging effective time information;

[0096] -Restricted paging quality threshold information;

[0097] Among them, 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 (such as a list of beams) the restricted paging is transmitted.

[0098] 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 beams.

[0099] Optionally, the “restricted paging effective time information” may be used to indicate at least one of the following information:

[0100] -The network will page the UE using restricted paging during the time;

[0101] - The network will page the UE on the restricted paging beam (one or more beams) within the time;

[0102] - During the time, the UE only needs to receive paging in some beams (for example, the beam configured by the restricted paging beam information).

[0103] Optionally, the "restricted paging effective time information" may be an absolute time or a relative time. If the "restricted paging effective time information" is a relative time, the effective time refers to the time calculated relative to when the UE receives the restricted paging effective time information.

[0104] Optionally, the “restricted paging quality threshold information” may be used to indicate at least one of the following information:

[0105] - The quality (RSRP / RSRQ) threshold and / or number of beams for the UE to receive paging in a restricted manner;

[0106] -The quality (RSRP / RSRQ) threshold and / or number of beams based on which the UE selects the beam to receive paging.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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 by itself.

[0111] 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.

[0112] 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.

[0113] Among them, optionally, the partial beam can be a beam indicated by the network through restricted paging beam information, or it can be a beam selected by the UE for receiving restricted paging according to restricted paging quality threshold information configured by the network.

[0114] Example 2

[0115] Optionally, in step 201, the user equipment UE receives a UE reporting restricted paging auxiliary information indication sent by the network. Optionally, the "UE reporting restricted paging auxiliary information indication" is used to indicate whether the UE needs to report the auxiliary information of the restricted paging, which may include but is not limited to: reporting the paging strategy expected by the UE. The paging strategy expected by the UE may include but is not limited to: normal paging, restricted paging, PEI of normal transmission, and PEI of restricted transmission.

[0116] 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, or an RRC-specific message (eg, an RRC reconfiguration message), or a MAC CE, or a physical layer indication (eg, a DCI).

[0117] 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).

[0118] Optionally, in step 203, when the user equipment UE satisfies at least one of the following conditions, the user equipment UE initiates a process of reporting restricted paging assistance information (e.g., paging policy expected by the UE) to the network, and the UE reports the restricted paging assistance information (e.g., paging policy expected by the UE) by including the restricted paging assistance information in an RRC message (e.g., UE assistance information UEAssistanceInformation):

[0119] -The UE is configured to report restricted paging assistance information to the network;

[0120] - The UE has an expected paging policy (wherein, as described above, the paging policy expected by the UE may include but is not limited to: normal paging, restricted paging, PEI with normal transmission, PEI with restricted transmission);

[0121] - since the UE is configured to report restricted paging assistance information to the network, the UE has not sent a message with restricted paging assistance information (e.g. UE Assistance Information) to the network;

[0122] - The restricted paging assistance information currently in the UE is different from the restricted paging assistance information in the last sent message (eg, UEAssistanceInformation) carrying the restricted paging assistance information.

[0123] Optionally, in step 205, the user equipment UE sets the message content in the 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):

[0124] - the transmission of the RRC message is initiated due to the provision of restricted paging assistance information;

[0125] - The UE has an expected paging policy (wherein, as described above, the paging policy expected by the UE may include but is not limited to: normal paging, restricted paging, PEI with normal transmission, PEI with restricted transmission);

[0126] -The UE has an expected paging strategy for this cell group.

[0127] Example 3

[0128] 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 paging failures of the UE working in the eDRX state may increase and the paging delay may increase. Therefore, eDRX and restricted paging cannot be used at the same time. According to Embodiment 1 and Embodiment 2, the specific implementation method may include at least one of the following:

[0129] - When the user equipment UE is operating eDRX, the UE always assumes that the base station will send paging on all transmission beams, and the UE can select the beam to receive the paging;

[0130] -The UE receives paging in a restricted manner unless the UE is performing eDRX;

[0131] - The network does not configure eDRX and restricted paging configuration information at the same time;

[0132] -Restricted paging configuration information will only appear when eDRX is not configured.

[0133] The eDRX may include RAN eDRX and / or CN eDRX.

[0134] 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.

[0135] Example 4

[0136] According to Embodiment 1 and Embodiment 2, optionally, the base station (e.g., gNB) may send an RRC message (e.g., UE radio paging information UERadioPagingInformation) to a core network (e.g., 5GC) or to other base stations, where the RRC message includes at least one of the following information:

[0137] - The paging strategy expected by the UE;

[0138] -Indication of whether the UE supports restricted paging;

[0139] -PEI restricted transfer indication;

[0140] -Restricted paging effective time information;

[0141] -Restricted paging quality threshold information.

[0142] The meaning of the above information is the same as that in Example 1 and Example 2.

[0143] Optionally, the RRC message may also be sent by the core network to the base station.

[0144] Example 5

[0145] Optionally, in step 501, the user equipment UE monitors PEI-O and receives PEI. Optionally, the PEI includes restricted paging configuration information.

[0146] Optionally, the restricted paging configuration may include but is not limited to at least one of the following:

[0147] -Restricted paging indication;

[0148] -Restricted paging beam information;

[0149] -Restricted paging effective time information;

[0150] -Restricted paging quality threshold information;

[0151] The meaning of the above information is the same as in Example 1.

[0152] Optionally, step 503 is the same as step 103 .
