Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, device, terminal and network-side equipment for determining a PEI resource location. Background Art

[0002] In 5G systems, power-saving designs for terminals (UEs) are essential. This is primarily due to the increased bandwidth, higher throughput, and more complex services supported by 5G, along with the correspondingly more sophisticated processing technologies. Power-saving optimization can reduce terminal power consumption, extend battery life, and thus improve the user experience. Therefore, it is crucial for the industrialization of 5G.

[0003] Current technology proposes an energy-saving solution for the radio resource control (RRC) idle state, supporting the use of the Paging Early Indication (PEI) in the RRC idle state as an indication of whether the physical downlink control channel (PDCCH) for scheduling paging messages needs to be monitored. By monitoring the PEI before monitoring the paging message, the terminal reduces the monitoring of invalid paging messages by the terminal and further reduces the power consumption of the terminal. Specifically, before receiving the paging message, the terminal first receives the PEI. If the terminal is instructed to receive subsequent paging messages, the terminal continues to receive the paging message. Otherwise, the terminal can enter a low-power or sleep state, thereby reducing the power consumption of the terminal. However, the existing method for determining the location of the PEI resource is not disclosed. Summary of the Invention

[0160] In embodiments of the present invention, the term "and / or" describes the association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0161] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0162] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0163] The technical solution provided in the embodiment of the present application can be applicable to a variety of systems, especially 5G systems. For example, the applicable system can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new air interface (NR) system, etc. These various systems include terminal equipment and network equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0164] The terminal involved in the embodiments of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called a user equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, or a user device, but is not limited in the embodiments of the present application.

[0165] The network side device involved in the embodiments of the present application may be a base station, which may include multiple cells providing services to the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (eNB or e-NodeB) in the Long Term Evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (HeNB), a relay node, a home base station (femto), a pico base station (pico), etc., and is not limited in the embodiments of the present application. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.

[0166] Network devices and terminal devices can each use one or more antennas for Multiple Input Multiple Output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the form and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO. It can also use diversity transmission, precoding transmission, or beamforming transmission.

[0167] The paging message in the 5G system consists of two parts, namely, paging PDCCH (Physical downlink control channel) and paging PDSCH (Physical Downlink Shared Channel). Based on the consideration of terminal energy saving, the paging reception of terminals in the RRC connected state and the inactive state in the 5G system needs to follow the discontinuous reception (DRX) principle. Usually, the network side will configure the paging cycle (i.e., DRX cycle) for the terminal through high-level signaling (RRC signaling and / or core network signaling), and the system information will also broadcast a default DRX cycle. The terminal determines the final DRX cycle for receiving paging based on the minimum value of the DRX configured by the high-level signaling and the default DRX cycle. The terminal monitors a paging occasion (PO) in each DRX cycle. A PO consists of a set of PDCCH monitoring opportunities (MO), which can include multiple time slots, such as subframes or orthogonal frequency division multiplex (OFDM) symbols. Paging downlink control information (DCI) is sent on the PDCCH MO. A paging frame (PF) is a radio frame that can contain one or more POs or the starting point of a PO. In multi-beam operation, the terminal assumes that all transmission beams repeatedly transmit the same paging messages and short messages. Selecting the appropriate beam and receiving paging and short messages is a terminal implementation issue.

[0168] Paging frames and paging opportunities are determined according to the following rules:

[0169] The system frame number (SFN) corresponding to the paging frame is determined according to the following formula:

[0170] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N);

[0171] Where T is the DRX cycle, whose unit is radio frame; N is the number of paging frames in each DRX cycle; PF_offset is the offset used to determine the paging frame; UE_ID = 5G-S-TMSI mod 1024, where 5G-S-TMSI is a 48-bit bit string.

[0172] Each paging frame contains Ns paging opportunities. The index of each PO is i_s, determined by the following formula: i_s = floor(UE_ID / N) mod Ns; where N is the number of paging frames in each DRX cycle; Ns is the number of POs in each PF; and UE_ID = 5G-S-TMSI mod 1024. Parameters T, N, PF_offset, and Ns are signaled via SIB1.

[0173] The UE determines the PDCCH monitoring opportunity for paging based on the paging search space, the first PDCCH monitoring opportunity ("firstPDCCH-MonitoringOccasionOfPO") configured in the "DownlinkConfigCommonSIB" field, and the number of PDCCH monitoring opportunities ("nrofPDCCHMonitoringOccasionPerSSB-InPO") per SSB. When the paging search space is configured with "SearchSpaceId = 0," the PDCCH monitoring opportunity is the same as the remaining minimum system information (RMSI).

[0174] When "SearchSpaceId = 0" is configured for the paging search space, Ns is 1 or 2. For Ns = 1, there is only one PO in the PF, and its starting point is the starting point of the first PDCCH monitoring opportunity. For Ns = 2, the PO is in the first half frame (i_s = 0) or the second half frame (i_s = 1) of the PF.

[0175] When the "SearchSpaceId" configured in the paging search space is not equal to 0, the UE monitors the (i_s+1)th PO. The PO is a set of "S2*X2" consecutive PDCCH monitoring opportunities, where S2 is the number of synchronization signal blocks (SSBs) actually transmitted based on the location information of the synchronization signal and PBCH block (SSB) carried by SIB1, and X2 represents the number of PDCCH monitoring opportunities corresponding to each SSB configured by "nrofPDCCHMonitoringOccasionPerSSB-InPO". If this value is not configured, X2 is equal to 1. Moreover, the [x*S2+K]th paging PDCCH monitoring opportunity in the PO corresponds to the Kth transmitted SSB, where x = 0, 1, ..., X2-1 and K = 1, 2, ..., S2. The PDCCH monitoring opportunities configured in the paging configuration do not overlap with uplink (UL) symbols and are numbered sequentially starting from 0 starting from the first paging monitoring opportunity in the PF. When "firstPDCCH-MonitoringOccasionOfPO" is configured, the starting point of the PDCCH MO of the (i_s+1)th PO is the (i_s+1)th value of the high-level parameter "firstPDCCH-MonitoringOccasionOfPO", otherwise, the starting point of the PDCCH MO of the (i_s+1)th PO is equal to i_s*S2*X2.

[0176] It should be noted that the above-mentioned method for determining PF and PO is only an optional implementation method of the embodiment of the present invention. Other methods for determining PF and PO are also applicable to this application and are not specifically limited here.

[0177] See Figure 2 , Figure 2 A flowchart of a method for determining a resource location of a paging advance indication (PEI) provided in an embodiment of the present invention includes:

[0178] Step 201: The terminal determines a radio frame number of a PEI frame, wherein the PEI frame includes X PEIs, and the X PEIs are used to indicate the paging status of paging opportunities PO in Y paging frames PF; wherein X is an integer greater than or equal to 1, and Y is an integer greater than 1;

[0179] Optionally, different PEI frames include different numbers of PEIs, for example, PEI frame A includes 3 PEIs and PEI frame B includes 4 PEIs; or, different PEI frames may include the same number of PEIs, for example, each PEI frame includes 4 PEIs.

[0180] Step 202: The terminal determines a PEI index;

[0181] Optionally, the PEI index is: an index of the PEI detected by the terminal in the PEI frame; or an index of a numerical value in first configuration information corresponding to the PEI detected by the terminal, where the first configuration information is used to configure a starting detection position of the PEI. For example, the first configuration information is "first PDCCH-MonitoringOccasionOfPEI".

[0182] Step 203: The terminal determines the resource location of the PEI detected by the terminal according to the radio frame number of the PEI frame and the PEI index.

[0183] In at least one optional embodiment of the present invention, the PEI detected by the terminal may also be referred to as the PEI monitored by the terminal or the PEI received by the terminal, which is not specifically limited herein.

[0184] Furthermore, the terminal receives, detects, or monitors the PEI at the determined resource location.

[0185] It should be noted that the PEI mentioned in the embodiments of the present invention is used to indicate at least one of the following:

[0186] Whether the paging downlink control information (Paging DCI) exists at the PO;

[0187] Whether the PO monitors paging DCI;

[0188] Whether the PO monitors paging messages;

[0189] Whether it is necessary to wake up and monitor paging messages during this paging cycle;

[0190] The paging message exists at the PO;

[0191] Monitor paging DCI at the PO;

[0192] Monitor paging messages at the PO;

[0193] It is necessary to wake up and monitor paging messages during this paging cycle.

[0194] In at least one embodiment of the present invention, one PEI is used to indicate the paging status of multiple POs, and the X PEIs include at least one of the following:

[0195] At least one first PEI, wherein the multiple POs indicated by the first PEI are POs in different PFs; or

[0196] At least one second PEI, where the multiple POs indicated by the second PEI are POs in the same PF.

[0197] Optionally, when X is greater than 1, the X PEIs include at least one first PEI and at least one second PEI;

[0198] or,

[0199] When X is equal to 1, the PEI is the first PEI.

[0200] Further, when X is equal to 1, the PEI is used to indicate part of the POs in Y PFs, and the number of POs included in the part of the POs is less than the number of POs included in the Y PFs.

[0201] For example, 1 PEI is used to indicate part of the POs in 2 PFs; if the 2 PFs include 8 POs, then the 1 PEI is used to indicate M POs in the 2 PFs, where M is less than or equal to 7; for example, M is equal to 7 or 6 or 5 or 4 or 3 or 2 or 1.

[0202] For another example, the PEI frame includes 1 PEI, and the PEI indicates a portion of POs in 1 paging frame, where the portion of POs is 3 POs included in 1 paging frame (the paging frame includes 4 POs in total).

[0203] In an optional embodiment of the present invention, the value of X is the number of POs included in a PF; and / or the value of Y is the number of POs corresponding to a PEI. For example, if a PF includes 4 POs, then X is 4; if a PEI corresponds to 3 POs, then Y is 3. That is, in this embodiment of the present invention, 4 PEIs are used to indicate the paging status of POs in 3 PFs.

[0204] In another optional embodiment of the present invention, when N1 cannot divide Ns and Ns cannot divide N1, the number of POs included in the Y PFs is the least common multiple of N1 and Ns; wherein N1 is the number of POs corresponding to one PEI, and Ns is the number of POs in each PF.

[0205] For example, N1=3, Ns=2, then the number of POs included in the Y PFs is 6 (ie, the least common multiple of 2 and 3).

[0206] In at least one embodiment of the present invention, step 201 includes:

[0207] The terminal determines the wireless frame number of the PEI frame based on the discontinuous reception DRX cycle, the number of PFs in each DRX cycle, the number of POs in each PF, the number of POs corresponding to a PEI, the offset for determining the PF, the offset for determining the PEI frame, the index of the PO in the PF, and at least one of the terminal identifier.

[0208] The wireless frame number of the PEI frame is related to the product of the first parameter and the second parameter;

[0209] The first parameter is related to at least one of the DRX cycle and the number of PFs in each DRX cycle;

[0210] The second parameter is related to at least one of the terminal identifier, the number of PFs in each DRX cycle, the number of POs in each PF, the index of the PO in the PF, and the number of POs corresponding to one PEI.

[0211] The sum of the radio frame number of the PEI frame and the third parameter, and the modulo operation result of the DRX cycle are equal to the product of the first parameter and the second parameter;

[0212] The third parameter is the sum of the offset for determining the PF and the offset for determining the PEI frame, or the third parameter is the offset for determining the PEI frame.

[0213] As an optional embodiment, in a case where the PEI index is the index of the PEI detected by the terminal in the PEI frame, the method further includes:

[0214] The terminal determines a second parameter according to the terminal identifier, the number of PFs in each DRX cycle, and parameter A;

[0215] Wherein, the parameter A satisfies:

[0216]

[0217] Among them, Ns is the number of POs in each PF; N1 is the number of POs corresponding to a PEI.

[0218] The second parameter satisfies: floor((UE_ID mod N) / A)*A;

[0219] Wherein, UE_ID is the terminal identifier; N is the number of PFs in each DRX cycle.

[0220] Specifically, if the radio frame number of the PEI frame is represented by PEI_SFN, then PEI_SFN satisfies the following formula:

[0221] (PEI_SFN+PF_offset+PEI_offset) mod T=(T div N)*floor((UE_ID mod N) / A)*A.

[0222] Alternatively, when the PEI index is an index of a numerical value in the first configuration information corresponding to the PEI detected by the terminal, the second parameter satisfies any of the following:

[0223] floor[floor(((UE_ID mod N)*Ns+i_s) / N1)*(N1 / Ns)];

[0224] floor[floor(((UE_ID mod N)*Ns+floor((UE_ID / N))mod Ns) / N1)*(N1 / Ns)];

[0225] Among them, UE_ID is the terminal identifier; N is the number of PFs in each DRX cycle; Ns is the number of POs in each PF; N1 is the number of POs corresponding to a PEI; i_s is the index of PO in PF.

[0226] For example, if the radio frame number of the PEI frame is represented by PEI_SFN, PEI_SFN satisfies the following formula:

[0227] (PEI_SFN+PF_offset+PEI_offset)mod T=(T div N)*floor[floor(((UE_IDmod N)*Ns+i_s) / N1)*(N1 / Ns)], or,

[0228] (PEI_SFN+PF_offset+PEI_offset)mod T=(T div N)*floor[floor(((UE_IDmod N)*Ns+floor((UE_ID / N))mod Ns) / N1)*(N1 / Ns)].

[0229] In yet another optional embodiment of the present invention, step 202 includes:

[0230] The terminal determines the PEI index according to at least one of the number of PFs in each DRX cycle, the number of POs in each PF, the number of POs corresponding to one PEI, the index of the PO in the PF, and the terminal identifier.

[0231] Wherein, the PEI index is the index of the PEI detected by the terminal in the PEI frame, and the first condition is met; or, the PEI index is the index of the value in the first configuration information corresponding to the PEI detected by the terminal,

[0232] The PEI index is equal to the modulo operation result of the fourth parameter and the number of POs in each PF;

[0233] Among them, the fourth parameter is related to at least one of the terminal identifier, the number of PFs in each DRX cycle, the number of POs in each PF, the number of POs corresponding to one PEI, and the index of PO in PF.

[0234] Optionally, the fourth parameter satisfies any of the following:

[0235] floor(((UE_ID mod N)*Ns+(floor(UE_ID / N)mod Ns)) / N1));

[0236] floor(((UE_ID mod N)*Ns+i_s) / N1);

[0237] Among them, UE_ID is the terminal identifier; N is the number of PFs in each DRX cycle; Ns is the number of POs in each PF; N1 is the number of POs corresponding to a PEI; i_s is the index of PO in PF.

[0238] Optionally, the first condition is that N1 cannot divide Ns, and Ns cannot divide N1. For example, PEI_i_s is used to represent the PEI index, and PEI_i_s satisfies the following formula:

[0239] PEI_i_s=floor(((UE_ID mod N)*Ns+(floor(UE_ID / N)mod Ns)) / N1))mod Ns, or PEI_i_s=floor(((UE_ID mod N)*Ns+i_s) / N1)mod Ns.

[0240] In another optional embodiment of the present invention, the PEI index is the index of the PEI detected by the terminal in the PEI frame, and when the first condition is not met,

[0241] The PEI index is equal to the modulo operation result of the fifth parameter and parameter B;

[0242] The fifth parameter is related to at least one of the terminal identifier, the number of PFs in each DRX cycle, and the number of POs in each PF;

[0243] The parameter B is related to at least one of the number of POs in each PF and the number of POs corresponding to one PEI.

[0244] Optionally, the first condition is that N1 cannot divide Ns, and Ns cannot divide N1. For example, PEI_i_s is used to represent the PEI index, and PEI_i_s satisfies the following formula:

[0245] PEI_i_s=(floor(UE_ID / N)mod Ns)mod B; B=max(Ns / N1,1).

[0246] In summary, in an embodiment of the present invention, the terminal and the network side device first determine the wireless frame number and PEI index where the PEI frame is located, and then determine the resource location of the PEI based on the wireless frame number and PEI index where the PEI frame is located; the number of POs indicated by one PEI in the PEI resource location determination method is flexible and can be applied to all situations where one PEI indicates multiple POs.

[0247] See Figure 3 , Figure 3 Another flow chart of a method for determining a PEI resource location according to an embodiment of the present invention, the method comprising:

[0248] Step 301: The network side device determines the radio frame number of the PEI frame, wherein the PEI frame includes X PEIs, and the X PEIs are used to indicate the paging status of the paging opportunities PO in Y paging frames PF; wherein X is an integer greater than or equal to 1, and Y is an integer greater than 1;

[0249] Optionally, different PEI frames include different numbers of PEIs, for example, PEI frame A includes 3 PEIs and PEI frame B includes 4 PEIs; or, different PEI frames may include the same number of PEIs, for example, each PEI frame includes 4 PEIs.

[0250] Step 302: The network side device determines the PEI index;

[0251] Optionally, the PEI index is: an index of the PEI sent by the network side device in the PEI frame; or an index of a numerical value in first configuration information corresponding to the PEI sent by the network side device, where the first configuration information is used to configure a starting detection position of the PEI. For example, the first configuration information is "first PDCCH-MonitoringOccasionOfPEI".

[0252] Step 303: The network side device determines the resource location of the PEI sent by the network side device according to the radio frame number of the PEI frame and the PEI index.

[0253] Furthermore, the network side device sends the PEI at the determined resource location.

[0254] Through the PEI resource determination method provided by the embodiment of the present invention, the PEI resource locations determined by the network side device and the terminal are consistent, so that the network side device can send PEI at the determined PEI resource location, and the terminal can receive or detect PEI at the PEI resource location.

[0255] In at least one embodiment of the present invention, one PEI is used to indicate the paging status of multiple POs, and the X PEIs include at least one of the following:

[0256] At least one first PEI, wherein the multiple POs indicated by the first PEI are POs in different PFs; or

[0257] At least one second PEI, where the multiple POs indicated by the second PEI are POs in the same PF.

[0258] Optionally, when X is greater than 1, the X PEIs include at least one first PEI and at least one second PEI;

[0259] or,

[0260] When X is equal to 1, the PEI is the first PEI.

[0261] Further, when X is equal to 1, the PEI is used to indicate part of the POs in Y PFs, and the number of POs included in the part of the POs is less than the number of POs included in the Y PFs.

[0262] For example, 1 PEI is used to indicate part of the POs in 2 PFs; if the 2 PFs include 8 POs, then the 1 PEI is used to indicate M POs in the 2 PFs, where M is less than or equal to 7; for example, M is equal to 7 or 6 or 5 or 4 or 3 or 2 or 1.

[0263] For another example, the PEI frame includes 1 PEI, and the PEI indicates a portion of POs in 1 paging frame, where the portion of POs is 3 POs included in 1 paging frame (the paging frame includes 4 POs in total).

[0264] In an optional embodiment of the present invention, the value of X is the number of POs included in a PF; and / or the value of Y is the number of POs corresponding to a PEI. For example, if a PF includes 4 POs, then X is 4; if a PEI corresponds to 3 POs, then Y is 3. That is, in this embodiment of the present invention, 4 PEIs are used to indicate the paging status of POs in 3 PFs.

[0265] In another optional embodiment of the present invention, when N1 cannot divide Ns and Ns cannot divide N1, the number of POs included in the Y PFs is the least common multiple of N1 and Ns; wherein N1 is the number of POs corresponding to one PEI, and Ns is the number of POs in each PF.

[0266] For example, N1=3, Ns=2, then the number of POs included in the Y PFs is 6 (ie, the least common multiple of 2 and 3).

[0267] In at least one embodiment of the present invention, step 301 includes:

[0268] The network side device determines the wireless frame number of the PEI frame based on the discontinuous reception DRX cycle, the number of PFs in each DRX cycle, the number of POs in each PF, the number of POs corresponding to a PEI, the offset for determining the PF, the offset for determining the PEI frame, the index of the PO in the PF, and at least one of the terminal identifiers.

[0269] The wireless frame number of the PEI frame is related to the product of the first parameter and the second parameter;

[0270] The first parameter is related to at least one of the DRX cycle and the number of PFs in each DRX cycle;

[0271] The second parameter is related to at least one of the terminal identifier, the number of PFs in each DRX cycle, the number of POs in each PF, the index of the PO in the PF, and the number of POs corresponding to one PEI.

[0272] The sum of the radio frame number of the PEI frame and the third parameter, and the modulo operation result of the DRX cycle are equal to the product of the first parameter and the second parameter;

[0273] The third parameter is the sum of the offset for determining the PF and the offset for determining the PEI frame, or the third parameter is the offset for determining the PEI frame.

[0274] As an optional embodiment, in a case where the PEI index is an index of the PEI sent by the network side device in the PEI frame, the method further includes:

[0275] The network side device determines the second parameter according to the terminal identifier, the number of PFs in each DRX cycle and parameter A;

[0276] Wherein, the parameter A satisfies:

[0277]

[0278] Among them, Ns is the number of POs in each PF; N1 is the number of POs corresponding to a PEI.

[0279] The second parameter satisfies: floor((UE_ID mod N) / A)*A;

[0280] Wherein, UE_ID is the terminal identifier; N is the number of PFs in each DRX cycle.

[0281] Specifically, if the radio frame number of the PEI frame is represented by PEI_SFN, then PEI_SFN satisfies the following formula:

[0282] (PEI_SFN+PF_offset+PEI_offset) mod T=(T div N)*floor((UE_ID mod N) / A)*A.

[0283] Alternatively, when the PEI index is an index of a numerical value in the first configuration information corresponding to the PEI sent by the network side device, the second parameter satisfies any of the following:

[0284] floor[floor(((UE_ID mod N)*Ns+i_s) / N1)*(N1 / Ns)];

[0285] floor[floor(((UE_ID mod N)*Ns+floor((UE_ID / N))mod Ns) / N1)*(N1 / Ns)];

[0286] Among them, UE_ID is the terminal identifier; N is the number of PFs in each DRX cycle; Ns is the number of POs in each PF; N1 is the number of POs corresponding to a PEI; i_s is the index of PO in PF.

[0287] For example, if the radio frame number of the PEI frame is represented by PEI_SFN, PEI_SFN satisfies the following formula:

[0288] (PEI_SFN+PF_offset+PEI_offset)mod T=(T div N)*floor[floor(((UE_IDmod N)*Ns+i_s) / N1)*(N1 / Ns)], or,

[0289] (PEI_SFN+PF_offset+PEI_offset)mod T=(T div N)*floor[floor(((UE_IDmod N)*Ns+floor((UE_ID / N))mod Ns) / N1)*(N1 / Ns)].

[0290] In yet another optional embodiment of the present invention, step 302 includes:

[0291] The network side device determines the PEI index based on at least one of the number of PFs in each DRX cycle, the number of POs in each PF, the number of POs corresponding to a PEI, the index of the PO in the PF, and the terminal identifier.

[0292] Wherein, the PEI index is the index of the PEI sent by the network side device in the PEI frame, and the first condition is met; or, the PEI index is the index of the value in the first configuration information corresponding to the PEI sent by the network side device,

[0293] The PEI index is equal to the modulo operation result of the fourth parameter and the number of POs in each PF;

[0294] Among them, the fourth parameter is related to at least one of the terminal identifier, the number of PFs in each DRX cycle, the number of POs in each PF, the number of POs corresponding to one PEI, and the index of PO in PF.

[0295] Optionally, the fourth parameter satisfies any of the following:

[0296] floor(((UE_ID mod N)*Ns+(floor(UE_ID / N)mod Ns)) / N1));

[0297] floor(((UE_ID mod N)*Ns+i_s) / N1);

[0298] Among them, UE_ID is the terminal identifier; N is the number of PFs in each DRX cycle; Ns is the number of POs in each PF; N1 is the number of POs corresponding to a PEI; i_s is the index of PO in PF.

[0299] Optionally, the first condition is that N1 cannot divide Ns, and Ns cannot divide N1. For example, PEI_i_s is used to represent the PEI index, and PEI_i_s satisfies the following formula:

[0300] PEI_i_s=floor(((UE_ID mod N)*Ns+(floor(UE_ID / N)mod Ns)) / N1))mod Ns, or PEI_i_s=floor(((UE_ID mod N)*Ns+i_s) / N1)mod Ns.

[0301] In another optional embodiment of the present invention, the PEI index is the index of the PEI sent by the network side device in the PEI frame, and if the first condition is not met,

[0302] The PEI index is equal to the modulo operation result of the fifth parameter and parameter B;

[0303] The fifth parameter is related to at least one of the terminal identifier, the number of PFs in each DRX cycle, and the number of POs in each PF;

[0304] The parameter B is related to at least one of the number of POs in each PF and the number of POs corresponding to one PEI.

[0305] Optionally, the first condition is that N1 cannot divide Ns, and Ns cannot divide N1. For example, PEI_i_s is used to represent the PEI index, and PEI_i_s satisfies the following formula:

[0306] PEI_i_s=(floor(UE_ID / N)mod Ns)mod B; B=max(Ns / N1,1).

[0307] In summary, in an embodiment of the present invention, the terminal and the network side device first determine the wireless frame number and PEI index where the PEI frame is located, and then determine the resource location of the PEI based on the wireless frame number and PEI index where the PEI frame is located; the number of POs indicated by one PEI in the PEI resource location determination method is flexible and can be applied to all situations where one PEI indicates multiple POs.

[0308] In order to more clearly describe the method for determining the resource location of a PEI provided in an embodiment of the present invention, an example of a terminal determining the resource location of a PEI is used for illustration below.

[0309] Example 1

[0310] Step 1: The terminal determines the radio frame number of the PEI frame. The PEI frame may include X PEIs, and the PEI in the PEI frame is used to indicate the paging status of the PO in Y paging frames. X is greater than or equal to 1, and Y is greater than 1.

[0311] like Figure 4 As shown in the figure, assuming N=T, Ns=4, 1 PEI indicates the paging status of 3 POs. At this time, 1 paging frame (PF) includes 4 POs, 3 PFs include 12 POs, and a total of 4 PEIs are required to indicate the paging status of 12 POs. Figure 4 As shown, X=4, Y=3; that is, the PEI frame determined by the UE includes 4 PEIs, and each PEI indicates the paging status of 3 different POs. For the first or fourth PEI in the PEI frame (that is, the first PEI or the fourth PEI is the second PEI mentioned in the embodiment of the present application), the PO indicated by the PEI is the PO in one PF frame, and the number of POs indicated by the PEI is less than the number of all POs in the PF frame. For the second or third PEI in the PEI frame (that is, the second PEI or the third PEI is the first PEI mentioned in the embodiment of the present application), the PO indicated by the PEI belongs to the POs in two different PF frames.

[0312] like Figure 5 As shown in the figure, assuming N=T, Ns=4, 1 PEI indicates the paging status of 5 POs. At this time, 1 paging frame (PF) includes 4 POs, 5 PFs include 20 POs, and a total of 4 PEIs are required to indicate the paging status of 20 POs. Figure 5 As shown, X=4, Y=5; that is, the PEI frame determined by the UE includes 4 PEIs, each PEI indicates the paging status of 5 different POs. For the PEI in the PEI frame, the PO indicated by the PEI belongs to the PO in two different PF frames, namely Figure 5 The PEI in is the first PEI mentioned in the examples of this application.

[0313] like Figure 6 As shown in the figure, assuming N=T, Ns=2, 1 PEI indicates the paging status of 3 POs. At this time, 1 paging frame (PF) includes 2 POs, 3 PFs include 6 POs, and a total of 2 PEIs are required to indicate the paging status of 6 POs. Figure 6 As shown, X=2, Y=3; that is, the PEI frame determined by the UE includes 2 PEIs, each PEI indicates the paging status of 3 different POs. For the PEI in the PEI frame, the PO indicated by the PEI belongs to the PO in two different PF frames, namely Figure 6 The PEI in is the first PEI mentioned in the examples of this application.

[0314] above Figure 4-Figure 6 If the PEI in M1 PEI frames indicates the paging status of the PO in M2 PFs, M1 is less than or equal to M2. The PEI frame includes at least one PEI.

[0315] Optionally, the number of POs indicated by PEI (N1) is 3 or 5, and the number of POs included in one PF (Ns) is 2 or 4. In this case, N1 and Ns cannot be divided by each other (i.e., N1 cannot be divided by Ns, and Ns cannot be divided by N1). Assuming that the PEI frame includes X PEIs, the PEI in the PEI frame is used to indicate the paging status of the POs in Y paging frames. In this case, the number of POs included in the Y paging frames is the least common multiple of N1 and Ns, X=Ns, Y=N1.

[0316] When N1 can divide Ns or Ns can divide N1, one PEI frame may include one PEI, which may indicate all POs in one PF frame, or one PEI frame may include multiple PEIs, which may indicate part of the POs in one PF frame, where the number of POs included in the partial POs is less than the number of POs included in one PF, or one PEI frame may include one PEI, which may indicate all POs in multiple PF frames. Figure 7 As shown, assuming that N=T, Ns=4, one PEI indicates the paging of four POs. In this case, one PEI frame includes one PEI, which indicates four POs in one PF. PEIs in different PEI frames indicate POs in different PFs.

[0317] To achieve the above Figures 4 to 7 The wireless frame number of the PEI frame is represented by PEI_SFN, and PEI_SFN satisfies the following formula:

[0318] (PEI_SFN+PF_offset+PEI_offset)mod T=(T div N)*floor((UE_ID mod N) / A)*A;

[0319] Among them, PEI_SFN is the radio frame number where PEI is located; PF_offset is the offset used to determine PF; PEI_offset is the offset used to determine PEI_SFN; T is the DRX cycle; N is the number of PFs in each DRX cycle; Ns is the number of POs in each PF; N1 is the number of POs corresponding to one PEI; UE_ID is 5G-S-TMSI mod 1024.

[0320] in,

[0321] Optionally, among the above parameters, PF_offset, T, N, and Ns can be paging parameters configured by the network-side device. PEI_offset can be configured by the network-side device or agreed upon by the protocol, and is not limited here. PEI_offset is used to describe the radio frame interval between the frame number (PEI_SFN) where the PEI is located and the frame number (PF) where the PO is located, and its unit is radio frame. N1 can be configured by the network-side device or agreed upon by the protocol, and is not limited here.

[0322] In step 2, the terminal determines the PEI index, which is the index of at least one PEI included in the PEI frame that the terminal needs to monitor, represented by PEI_i_s. For example, if a PEI frame includes X PEIs, the PEI index may be 0, 1, 2, ..., X-1. Specifically, if X = 1, then PEI_i_s = 0; if X = 2, then PEI_i_s = 0 or 1.

[0323] PEI_i_s satisfies the following formula:

[0324] When N1 is not an integer multiple of Ns and Ns is not an integer multiple of N1,

[0325] PEI_i_s=floor(((UE_ID mod N)*Ns+(floor(UE_ID / N)mod Ns)) / N1))mod Ns, or PEI_i_s=floor(((UE_ID mod N)*Ns+i_s) / N1)mod Ns.

[0326] In other cases (i.e. when N1 is an integer multiple of Ns, or Ns is an integer multiple of N1),

[0327] PEI_i_s=(floor(UE_ID / N)mod Ns)mod B.

[0328] Among them, PEI_i_s is the index of at least one PEI included in the PEI frame; N is the number of PFs in each DRX cycle; Ns is the number of POs in each PF; N1 is the number of POs corresponding to one PEI; i_s is the index of PO in the PF; B=max(Ns / N1,1); UE_ID is 5G-S-TMSI mod1024.

[0329] In step 3, the UE can determine the SFN where the PEI is located through step 1, and then determine the index of the PEI in at least one PEI included in the PEI frame based on the PEI index determined in step 2. The PEI index can be used to determine the specific resource location of the PEI in the PEI frame. For example, if the PEI frame includes two PEIs, then the network-side device configuration firstPDCCH-MonitoringOccasionOfPEI includes two values. The resource location of the PEI corresponding to PEI_i_s=0 in the PEI frame is determined according to the first value in firstPDCCH-MonitoringOccasionOfPEI, and the resource location of the PEI corresponding to PEI_i_s=1 in the PEI frame is determined according to the second value in firstPDCCH-MonitoringOccasionOfPEI. The following describes in more detail how to determine the resource location of the PEI based on the PEI index when the PEI frame is determined.

[0330] For example, the UE determines the PDCCH monitoring opportunity of the PEI based on the paging search space and the PEI's PDCCH monitoring opportunity "firstPDCCH-MonitoringOccasionOfPEI" configured in the "DownlinkConfigCommonSIB" field, and the number of paging PDCCHMO corresponding to an SSB "nrofPDCCHMonitoringOccasionPerSSB-InPO". When the paging search space (paging search space) is configured with "SearchSpaceId = 0", the PDCCH monitoring opportunity of the PEI is the same as the remaining minimum system information (RMSI).

[0331] When the "SearchSpaceId" configured in the paging search space configuration is not equal to 0, the UE monitors the (PEI_i_s+1)th PEI. When "firstPDCCH-MonitoringOccasionOfPEI" is configured, the starting point of the PDCCH MO of the (PEI_i_s+1)th PEI is the (PEI_i_s+1)th value of the high-level parameter "first PDCCH-Monitoring OccasionOfPEI". Otherwise, the starting point of the PDCCH MO of the (PEI_i_s+1)th PEI is equal to (PEI_i_s*S*X1). S is the number of SSBs actually transmitted determined based on the location information of the synchronization signal block (SSB) carried by SIB1. X1 represents the number of PDCCH MOs corresponding to each SSB configured by "nrofPDCCHMonitoringOccasionPerSSB-InPEI". If this value is not configured, X1 is equal to 1.

[0332] According to the above method, the terminal and the network side device can determine the resource location of the PEI according to the determined PEI frame and PEI index. The PEI is the PEI that the UE needs to monitor, and the PEI is used to indicate the paging status of the PO that the UE needs to monitor.

[0333] Step 4: The terminal receives or detects PEI at the resource location.

[0334] In 5G, many signals are sent through different beams. PEI is likely to be the same as paging DCI, with multiple PEI opportunities. The Kth PEI opportunity corresponds to the Kth SSB. In this case, the PEI beam sent by the Kth PEI opportunity corresponds to the SSB beam at the Kth SSB position. That is, the number of PEI opportunities is the same as the number of SSBs actually transmitted over SIB1. When the PEI is a multi-beam PEI, Example 1's solution for determining the PEI resource location includes determining multiple resource locations corresponding to the multi-beam PEI, such as determining the PEI resource location as the starting position of the PEI of the first beam based on the PEI frame and PEI index.

[0335] In step 4, the network side device sends a PEI signal at the resource location, and the corresponding step 4 behavior on the terminal side is that the terminal receives the PEI signal at the resource location. However, it does not mean that the network side device will definitely send a PEI signal at the sending location. Whether the network side device will send a PEI signal at the sending location depends on the specific function of the PEI signal. For example, if the PEI is used to indicate the presence of paging DCI at the PO, the base station will only send PEI at the resource location when there is paging DCI at the PO. At this time, the terminal will receive or detect PEI at the resource location where the PEI is determined, and finally the terminal receives PEI. When there is no paging DCI at the PO, the base station will not send PEI at the determined resource location. At this time, the terminal will receive or detect PEI at the resource location where the PEI is determined, and finally the terminal cannot receive PEI.

[0336] Example 2

[0337] Step 1: The terminal determines the radio frame number of the PEI frame. The PEI frame may include X PEIs, and the PEI in the PEI frame is used to indicate the paging status of the PO in Y paging frames. X is greater than or equal to 1, and Y is greater than 1.

[0338] like Figure 8 As shown in the figure, assuming N=T, Ns=4, 1 PEI indicates the paging status of 3 POs. At this time, 1 paging frame (PF) includes 4 POs, 3 PFs include 12 POs, and a total of 4 PEIs are required to indicate the paging status of 12 POs. The PEI frame determined by the UE for the 1st PO to the 6th PO is Figure 6 The first PEI frame is the 1st PEI frame (X=2 in the PEI frame), the PEI frame determined by the UE for the 7th PO to the 9th PO is the 2nd PEI frame (X=1 in the PEI frame), and the PEI frame determined by the UE for the 10th PO to the 12th PO is the 3rd PEI frame (X=1 in the PEI frame). The first PEI frame includes 2 PEIs, and the second PEI and the third PEI frames each include 1 PEI. Each PEI indicates the paging status of 3 different POs. For the first PEI in the first PEI frame or the first PEI in the third PEI frame (that is, the second PEI mentioned in the embodiment of the present application), the PO indicated by the PEI is the PO in 1 PF frame, and the number of POs indicated by the PEI is less than the number of all POs in the PF frame. For the second PEI in the first PEI frame or the first PEI in the second PEI frame (ie, the first PEI mentioned in the embodiment of the present application), the PO indicated by the PEI belongs to POs in two different PF frames.

[0339] like Figure 9As shown, assuming that N=T, Ns=4, 1 PEI indicates the paging status of 5 POs. At this time, 1 paging frame (PF) includes 4 POs, and 5 PFs include 20 POs. A total of 4 PEIs are required to indicate the paging status of 20 POs. The number of PEI frames determined by the UE corresponding to the POs in the 5 PFs is 4, that is, the PEIs in the 4 PEI frames are used to indicate the paging status of the POs in the 5 PFs. At this time, the number of PEI frames is less than the number of PFs. Figure 9 Each PEI frame shown includes one PEI, that is, X=1. That is, the PEI frame determined by the UE includes one PEI, and each PEI indicates the paging status of five different POs. For the four PEIs in the four PEI frames, the POs indicated by the PEIs belong to the POs in two different PF frames, that is, Figure 9 Each PEI in is the first PEI mentioned in the examples of this application.

[0340] like Figure 10 , assuming that N = T, Ns = 1, 1 PEI indicates the paging status of 3 POs. 1 PEI frame includes 1 PEI, that is, Figure 10 Each PEI shown includes one PEI, that is, X=1. The PEI can indicate all POs in multiple PF frames. Figure 10 As shown, at this time, 1 PEI frame includes 1 PEI, which indicates 3 POs in 3 PFs. PEIs in different PEI frames indicate POs in different PFs, i.e. Figure 10 Each PEI in is the first PEI mentioned in the examples of this application.

[0341] The number of PEIs included in different PEI frames may be different.

[0342] Optionally, the PEI frame includes one PEI, which can indicate some POs in multiple PFs, where the number of the partial POs is less than the number of all POs in the multiple PFs. Figure 9 For example, the PEI in the first PEI frame in the paging frame indicates that the 5 POs include the 4 POs in the first PF and the 1st PO in the second PF. The number of POs indicated by the PEI is less than the 8 POs included in the two PFs. The PEI frame includes 1 PEI, and the PEI indicates part of the POs in 1 paging frame, and the part of the POs is 3 POs included in 1 paging frame.

[0343] To achieve the above Figures 8 to 10 The wireless frame number of the PEI frame is represented by PEI_SFN, and PEI_SFN satisfies the following formula:

[0344] (PEI_SFN+PF_offset+PEI_offset)mod T=(T div N)*floor[floor(((UE_IDmod N)*Ns+i_s) / N1)*(N1 / Ns)], or,

[0345] (PEI_SFN+PF_offset+PEI_offset)mod T=(T div N)*floor[floor(((UE_IDmod N)*Ns+floor((UE_ID / N))mod Ns) / N1)*(N1 / Ns)];

[0346] Among them, PEI_SFN is the radio frame number where PEI is located; PF_offset is the offset used to determine PF; PEI_offset is the offset used to determine PEI_SFN; T is the DRX cycle; N is the number of PFs in each DRX cycle; i_s is the index of PO in PF; Ns is the number of POs in each PF; N1 is the number of POs corresponding to one PEI; UE_ID is 5G-S-TMSImod 1024.

[0347] Among the above parameters, PF_offset, T, N, and Ns can be paging parameters configured by the network device. PEI_offset can be configured by the network device or agreed upon by the protocol and is not limited here. PEI_offset is used to describe the radio frame interval between the PEI frame number (PEI_SFN) and the PO frame number (PF), and its unit is radio frame. N1 can be configured by the network device or agreed upon by the protocol and is not limited here.

[0348] Step 2: The terminal determines the PEI index. The terminal device determines the PEI index (PEI_i_s), and the network-side device broadcasts firstPDCCH-MonitoringOccasionOfPEI, which includes Ns values. The PEI index is the index of the value in firstPDCCH-MonitoringOccasionOfPEI corresponding to the PEI. For example, if Ns = 1, firstPDCCH-MonitoringOccasionOfPEI includes 2 values. The PEI with PEI_i_s = 0 corresponds to the first value in firstPDCCH-MonitoringOccasionOfPEI, and the PEI with PEI_i_s = 1 corresponds to the second value in firstPDCCH-MonitoringOccasionOfPEI.

[0349] PEI_i_s satisfies the following formula:

[0350] PEI_i_s=floor(((UE_ID mod N)*Ns+(floor(UE_ID / N)mod Ns)) / N1))mod Ns, or PEI_i_s=floor(((UE_ID mod N)*Ns+i_s) / N1)mod Ns.

[0351] Among them, PEI_i_s is the index of the value in firstPDCCH-MonitoringOccasionOfPEI corresponding to PEI; N is the number of PFs in each DRX cycle; Ns is the number of POs in each PF; N1 is the number of POs corresponding to a PEI; i_s is the index of PO in PF; UE_ID is 5G-S-TMSI mod 1024.

[0352] In step 3, the UE can determine the SFN where the PEI is located through step 1, and then according to the index (PEI index) of the value in firstPDCCH-MonitoringOccasionOfPEI corresponding to the PEI determined in step 2 above, the value corresponding to the PEI index can be used to determine the specific resource location of the PEI in the PEI frame. For example, the UE determines the specific frame number of the PEI frame. Assuming that the PEI index = 0, the PEI corresponds to the first value in firstPDCCH-MonitoringOccasionOfPEI at this time. This value clarifies the specific location of the PEI in the PEI frame number.

[0353] For example, the UE determines the PDCCH monitoring opportunity of the PEI based on the paging search space and the PEI's PDCCH monitoring opportunity "firstPDCCH-MonitoringOccasionOfPEI" configured in the "DownlinkConfigCommonSIB" field, and the number of paging PDCCHMO corresponding to an SSB "nrofPDCCHMonitoringOccasionPerSSB-InPO". When the paging search space (paging search space) is configured with "SearchSpaceId = 0", the PDCCH monitoring opportunity of the PEI is the same as the remaining minimum system information (RMSI).

[0354] When the "SearchSpaceId" configured in the paging search space is not equal to 0, when "firstPDCCH-MonitoringOccasionOfPEI" is configured, the UE monitors the PEI at the position corresponding to the (PEI_i_s+1)th value of "firstPDCCH-Monitoring Occasion Of PEI". When "firstPDCCH-MonitoringOccasionOfPEI" is not configured, the starting point of the PDCCH MO of the PEI that the UE monitors is equal to (PEI_i_s*S*X1). S is the number of SSBs actually transmitted determined based on the synchronization signal block (Synchronization Signal and PBCH block, SSB) position information carried by SIB1, and X1 represents the number of PDCCH MOs corresponding to each SSB configured by "nrofPDCCHMonitoringOccasionPerSSB-InPEI". If this value is not configured, X1 is equal to 1.

[0355] According to the above method, the terminal and the network side device can determine the resource location of the PEI according to the determined PEI frame and PEI index. The PEI is the PEI that the UE needs to monitor, and the PEI is used to indicate the paging status of the PO that the UE needs to monitor.

[0356] Step 4: The terminal receives or detects PEI at the resource location.

[0357] In 5G, many signals are sent through different beams. PEI is likely to be the same as paging DCI, with multiple PEI opportunities. The Kth PEI opportunity corresponds to the Kth SSB. In this case, the PEI beam sent by the Kth PEI opportunity corresponds to the SSB beam at the Kth SSB position. That is, the number of PEI opportunities is the same as the number of SSBs actually transmitted over SIB1. When the PEI is a multi-beam PEI, Example 1's solution for determining the PEI resource location includes determining multiple resource locations corresponding to the multi-beam PEI, such as determining the PEI resource location as the starting position of the PEI of the first beam based on the PEI frame and PEI index.

[0358] In step 4, the network side device sends a PEI signal at the resource location, and the corresponding step 4 behavior on the terminal side is that the terminal receives the PEI signal at the resource location. However, it does not mean that the network side device will definitely send a PEI signal at the sending location. Whether the network side device will send a PEI signal at the sending location depends on the specific function of the PEI signal. For example, if the PEI is used to indicate the presence of paging DCI at the PO, the base station will only send PEI at the resource location when there is paging DCI at the PO. At this time, the terminal will receive or detect PEI at the resource location where the PEI is determined, and finally the terminal receives PEI. When there is no paging DCI at the PO, the base station will not send PEI at the determined resource location. At this time, the terminal will receive or detect PEI at the resource location where the PEI is determined, and finally the terminal cannot receive PEI.

[0359] In summary, the resource location determination method of PEI provided in the embodiment of the present invention is flexible in the number of POs indicated by one PEI, and is applicable to all situations where one PEI indicates multiple POs; for example, one PEI can indicate the paging status of three POs in one PF, and one PEI indicates the paging status of some POs in all POs in multiple PF frames, and one PEI indicates the paging status of one, two or four POs in one PF, and one PEI indicates the paging status of all POs in multiple PFs.
