[0002] In the Radio Resource Control idle state (RRC_IDLE state) or the Radio Resource Control inactive state (RRC_INACTIVE state), a terminal needs to monitor the physical downlink control channel (PDCCH) related to paging, also known as type 2-PDCCH.

[0003] After the terminal detects the PDCCH related to paging, the terminal can parse the DCI. The DCI may contain a short message, so that the terminal can obtain an alarm message or perform system information update. In addition, the DCI may also contain scheduling information, so that the terminal receives the physical downlink shared channel (PDSCH) related to paging, thereby obtaining a paging message, and further initiating a random access process to enter the connected state (RRC_CONNECTED state).

[0004] Among them, the paging occasion (PO) can represent the time domain position of the PDCCH related to paging, and can be composed of the monitoring occasions of multiple PDCCHs related to paging, and the monitoring occasion of the PDCCH related to paging can also be called the PDCCH monitoring occasion (PMO). Therefore, one PO can contain multiple PMOs.

[0005] During the process of monitoring the PDCCH related to paging, in order to avoid unnecessary monitoring to save the power consumption of the terminal, in the RRC_IDLE state or the RRC_INACTIVE state, a network device can configure paging early indication information (PEI), and the PEI can be used to indicate whether the terminal needs to continue to monitor the PDCCH related to paging, so as to achieve the purpose of saving power consumption.

[0063] In addition, the terminal can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted; it can be deployed on water (such as a ship, etc.); it can also be deployed in the air (such as an airplane, a balloon, a satellite, etc.).

[0064] The terminal may include a device with wireless communication capabilities, such as a chip system, a chip, a chip module, etc. Among them, the chip system may include a chip and may also include other discrete devices.

[0065] Exemplarily, the terminal may be a mobile phone, a tablet (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in unmanned autonomous driving, a wireless terminal device in remote medical, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, or a wireless terminal device in smart home, etc.

[0066] Specifically, the network device may be a device with transceiver capabilities, which may be a device for communicating with the terminal, responsible for radio resource management (RRM) on the air interface side, quality of service (QoS) management, data compression and encryption, data transceiver, etc.

[0067] The network device may be a base station (BS) in a communication system or a device deployed in a radio access network (RAN) to provide wireless communication capabilities. For example, a base transceiver station (BTS) in a GSM or CDMA communication system, a Node B (NB) in a WCDMA communication system, an evolved Node B (eNB or eNodeB) in an LTE communication system, a next generation evolved Node B (ng-eNB) in an NR communication system, a next generation Node B (gNB) in an NR communication system, a master node (MN) in a dual-link architecture, a secondary node (SN) in a dual-link architecture, etc., and no specific limitation is made thereto.

It can include a centralized unit (CU) and a distributed unit (DU), such as gNB-CU and gNB-DU; it can also include an active antenna unit (AAU). Among them, the CU can implement some functions of the network device, and the DU can also implement some functions of the network device. For example, the CU is responsible for processing non-real-time protocols and services and implementing the functions of the radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer, and packet data convergence protocol (PDCP) layer. The DU is responsible for processing physical layer protocols and real-time services and implementing the functions of the radio link control (RLC) layer, medium access control (MAC) layer, and physical (PHY) layer. In addition, the AAU can implement some physical layer processing functions, radio frequency processing, and related functions of active antennas. Since the information in the RRC layer will ultimately become the information in the PHY layer or be transformed from the information in the PHY layer, under this network deployment, high-layer signaling (such as RRC layer signaling) can be considered to be sent by the DU or jointly sent by the DU and the AAU. It can be understood that the network device can include at least one of the CU, DU, and AAU. In addition, the CU can be classified as a network device in the radio access network (RAN) or as a network device in the core network, and no specific limitation is made in this regard.

As Figure 1 shown, the wireless communication system 10 can include a network device 110 and a terminal 120. The network device 110 and the terminal 120 can communicate wirelessly.

[0076] Figure 1 This is only an example of the network architecture of a wireless communication system and does not limit the network architecture of the communication system according to the embodiments of the present application. For example, in the embodiments of the present application, the wireless communication system may further include a server or other devices. For another example, in the embodiments of the present application, the wireless communication system may include multiple network devices and / or multiple terminal devices.

[0077] First, some terms involved in the embodiments of the present application will be explained to facilitate the understanding of those skilled in the art.

[0078] 1. Physical Downlink Control Channel (PDCCH) related to paging

[0079] Generally speaking, in the Radio Resource Control (RRC) idle state or the RRC inactive state, the terminal needs to monitor the PDCCH related to paging, also known as type 2-PDCCH. The Radio Network Temporary Identity (RNTI) of the PDCCH related to paging is P-RNTI, and the format of the Downlink Control Information (DCI) used is DCI format 1-0.

[0080] When the terminal detects a PDCCH related to paging (the CRC is successfully scrambled with the P-RNTI), the terminal can then parse the DCI. This DCI may contain a short message, enabling the terminal to obtain an alert message or perform system information update. Additionally, this DCI may also contain scheduling information, enabling the terminal to receive the physical downlink share channel (PDSCH) related to paging, thereby obtaining the paging message and further initiating a random access procedure to enter the connected state (RRC_CONNECTED state).

[0081] Among them, the functions of the paging message are as follows:

[0082] (1) Send a call request to the terminal in the RRC_IDLE state;

[0083] (2) Notify the terminal in the RRC_IDLE state, RRC_INACTIVE state, or RRC_CONNECTED state that the system information has changed;

[0084] (3) Instruct the terminal to start receiving the primary notification and / or secondary notification of the Earthquake and Tsunami Warning System (ETWS); instruct the terminal to start receiving the Commercial Mobile Alert System (CMAS) notification.

[0085] In addition, before obtaining the paging message, the terminal needs to complete time-frequency synchronization using reference signals (e.g., SSB), and complete the adjustment of Automatic Gain Control (AGC).

[0086] The listening opportunity of the PDCCH related to paging can be configured by the search space set (SSS).

[0087] In the RRC_IDLE state or RRC_INACTIVE state, the terminal can use the Discontinuous Reception (DRX) mechanism to receive the paging message to reduce power consumption. A DRX cycle can contain at least one Paging Frame (PF).

[0088] Among them, a PF can be a radio frame or a system frame, which can contain one or more POs or a PO starting point.

[0089] Among them, the paging occasion (PO) can be used to determine the starting point of the monitoring occasion within the PF, can indicate the time domain position of the PDCCH related to paging, can be used to transmit paging downlink control information (paging DCI), can be composed of multiple subframes, multiple time slots or multiple OFDM symbols, and can be composed of the monitoring occasions of multiple PDCCHs related to paging. The monitoring occasion of the PDCCH related to paging can also be referred to as the paging PDCCH monitoring occasion (PMO). Therefore, one PO can contain multiple PMOs.

[0090] Among them, the PMO is a sequential multiple monitoring occasions starting from the starting point, and the PMO is associated with the actually transmitted SSB one-to-one.

[0091] Among them, the terminal can determine the position of the PF or PO to which it belongs according to its own device identifier (UE_ID).

[0092] 2. Radio Resource Management (RRM) measurement

[0093] In the RRC_IDLE state or the RRC_INACTIVE state, the terminal also needs to perform periodic RRM measurements. Among them, the RRM measurement can include serving cell measurement and neighboring cell measurement.

[0094] The neighboring cell measurement can include:

[0095] The network device gives a frequency point, and the terminal can perform cell search and measurement on this frequency point; or,

[0096] The network device gives a frequency point and a physical cell ID (PCI), and the terminal can perform cell search and measurement on this frequency point using this PCI; or,

[0097] The network device does not give a frequency point or a PCI, and the terminal can independently perform cell search and measurement.

[0098] The neighboring cell measurement can be further divided into intra-frequency measurement and inter-frequency measurement.

[0099] For example, if the center frequency point and subcarrier spacing of the SSB in the measurement object of the neighboring cell are the same as those of the SSB of the serving cell, then this measurement is an intra-frequency measurement.

[0100] For example, if the center frequency point or subcarrier spacing of the SSB in the measurement object of the neighboring cell is different from that of the SSB of the serving cell, then this measurement is an inter-frequency measurement.

[0101] In the RRC_IDLE state or RRC_INACTIVE state, the terminal generally needs to perform an RRM measurement of the serving cell within one paging cycle. The paging cycle is also called the DRX cycle, or the idle state - DRX cycle.

[0102] Therefore, in the RRC_IDLE state or RRC_INACTIVE state, listening to the PDCCH related to paging and performing RRM measurement are the main tasks of the terminal.

[0103] 3. Paging Early Indication (PEI)

[0104] To implement listening to the PDCCH related to paging and performing RRM measurement, generally, the network device needs to page the terminal in advance to wake up from deep sleep to process 3 Synchronization Signal Block Bursts (SS / PBCH block burst, SSBburst), achieving a certain time-frequency synchronization to listen to the PDCCH related to paging and perform RRM measurement simultaneously.

[0105] During the process of listening to the PDCCH related to paging, in order to avoid unnecessary listening to save the power consumption of the terminal, in the RRC_IDLE state or RRC_INACTIVE state, the network device can configure the PEI, which can be used to indicate whether the terminal needs to continue listening to the PDCCH related to paging, so as to achieve the purpose of saving power. Among them, the PEI can be downlink control information or a sequence, etc.

[0106] When the PEI is configured, the terminal can wake up from deep sleep to process 1 SSB burst to achieve a certain time-frequency synchronization to detect the PEI.

[0107] If the PEI indicates the listening opportunity for continuing to listen to the PDCCH related to paging, then the terminal continues to process the remaining 2 SSB bursts and continues to listen to the PDCCH related to paging.

[0108] If the PEI indicates that there is no need to continue listening to the PDCCH related to paging, then the terminal returns to deep sleep.

[0109] When the group paging rate is 10%, the probability that the terminal needs to monitor the PDCCH related to paging is 10%. Therefore, with a 10% probability, the terminal needs to process 3 SSB bursts, monitor the PDCCH related to paging, and perform RRM measurements. With a 90% probability, the terminal only needs to process 1 SSB burst and perform RRM measurements. Therefore, with a 90% probability, the terminal processes fewer signals / channels, has a shorter wake-up time (if no signals / channels are processed after waking up from deep sleep, it is in light sleep), and consumes less power.

[0110] In summary, by using PEI, the terminal can achieve the purpose of power saving.

[0111] 4. PEI Occasion (PEI-O)

[0112] Similar to PO, PEI-O can be composed of a set of PEI PDCCH monitoring occasions, indicating the time domain position of the PEI PDCCH. Among them, the PEI PDCCH monitoring occasion can also be called the PEI monitoring occasion (PEI-MO). Therefore, PEI-O can include multiple PEI-MOs.

[0113] Since the PEI-MO is associated with the SSB within 5 milliseconds one by one, the terminal can select which PEI-MO associated with the SSB to monitor according to the measurement result of the SSB.

[0114] 5. PEI Group, PF Group, PO Group, Subgroups within PO

[0115] PEI can indicate whether the UE group corresponding to a PO needs to monitor the PO. Among them, the power saving comes from the premise that the probability of a UE group corresponding to a PO being paged is small (such as 10%). However, when the probability of a UE group corresponding to a PO being paged is large, the probability that PEI indicates that the UE group corresponding to a PO needs to monitor the PO is also large, and power saving may not be achieved at this time.

[0116] To achieve power saving, a solution can be to introduce a UE subgroup, which represents a subset of the UE group corresponding to a PO. When PEI indicates whether a subset of the UE group corresponding to a PO needs to monitor the PO, since the probability of a subset of the UE group corresponding to a PO being paged can be small, the probability that PEI indicates that a subset of the UE group corresponding to a PO needs to monitor is also small.

[0117] It should be noted that, for the convenience of description, in the embodiments of the present application, a UE group corresponding to one PEI-O may be referred to as a "PEI group", a UE group corresponding to one PF may be referred to as a "PF group", a UE group corresponding to one PO may be referred to as a "PO group", and a subset of the UE group within one PO may be referred to as a "sub-group within the PO".

[0118] Since the embodiments of the present application need to consider the "sub-group within the PO", the network device may configure a parameter Nsg, where Nsg represents the number of all sub-groups within one PO (i.e., the number of subsets of all UE groups within one PO). When Nsg = 1, the "sub-group within the PO" is equivalent to the "PO group".

[0119] In addition, PEI-O in the embodiments of the present application can be understood either as a paging early indication opportunity or as a "PEI group" (this PEI group monitors the PEI within this paging early indication opportunity), and no specific limitation is made in this regard.

[0120] PF in the embodiments of the present application can be understood either as a paging frame or as a "PF group" (this PF group monitors paging within this paging frame), and no specific limitation is made in this regard.

[0121] PO in the embodiments of the present application can be understood either as a paging opportunity or as a PO group (this PO group monitors paging within this paging opportunity), and no specific limitation is made in this regard.

[0122] In summary, PEI-O represents the time domain position of the PEI PDCCH. However, the current standard protocol specified by 3GPP has not standardized the design scheme of PEI-O. Therefore, how to further design the current PEI, such as how to determine the position of PEI-O, the number of bits of the PEI PDCCH or the downlink control information (DCI) corresponding to the PEI PDCCH, the bit position of the PO group or the UE sub-group within the PO in the PEI PDCCH or the DCI corresponding to the PEI PDCCH, etc., is an urgent problem to be solved.

[0123] In order to realize the design of PEI-O, the following embodiments of the present application will specifically describe how to determine the position of PEI-O, how to determine the number of bits of the PEI PDCCH or the DCI corresponding to the PEI PDCCH, how to determine the bit position of the PO group or the sub-group within the PO in the PEI PDCCH, how to determine the bit position of the PO group or the sub-group within the PO in the DCI corresponding to the PEI PDCCH, etc.

[0145] i_pf_ref: Index of the first PF corresponding to the PEI;

[0146] i_s_ref: Index of the first PO within the first PF corresponding to the PEI;

[0147] Y: Number of bits of the first indication information;

[0148] It should be noted that for PEI_offset, it can be understood that PEI_offset is the offset of PEI-F in T, and the time unit is frames, so it is simply referred to as the frame offset. For example, the absolute time of the DRX cycle is 320 milliseconds (it can also be said that the DRX cycle is 32, corresponding to T = 32), and the frame offset is 1. The terminal calculates SFN_pei through UE_ID and PEI_offset, that is, the position of PEI-F (represented by the frame number).

[0149] For the target PO, it can be understood that the target PO is the PO that the terminal needs to monitor, and the target PO is determined by the terminal according to the UE_ID. For the network, there can be multiple PFs within one DRX cycle, and there can be multiple POs within one PF. The terminal determines the PO to be monitored according to the UE_ID, that is, the target PO.

[0150] For the PF of the target PO, it can be understood as the PF where the target PO is located, belongs to, corresponds to, or is in.

[0151] For the PEI of the target PO, it can be understood as the PEI where the target PO is located, belongs to, corresponds to, or is in.

[0152] For the first indication information, it can be understood as public information, such as information related to short messages and information on the availability of Tracking Reference Signal (TRS).

[0153] In addition, the above English abbreviations used in the embodiments of this application may have different expressions in different standard protocols, but they only have the same meaning or interpretation, and all belong to the scope to be protected by this application, and no specific restrictions are made in this regard.

[0154] 1. How to determine the position of PEI-O

[0155] 1) Position of PEI-O

[0156] It should be noted that, combined with the content in the above "4. PEI Timing", it can be known that PEI-O can be composed of a set of PEI PDCCH monitoring opportunities (also known as PEI-MO), indicating the time domain position of the PEI PDCCH.

[0157] Regarding the position of PEI-O, it can be understood as the time-domain position of PEI-O. For example, the position of the time unit where PEI-O is located, the position of the starting time unit of PEI-O, the position of the ending time unit of PEI-O, the duration unit of PEI-O, etc.

[0158] In addition, the starting time unit of PEI-O can also be referred to as the starting position of PEI-O or the starting time-domain position of PEI-O, the ending time unit of PEI-O can also be referred to as the ending position of PEI-O or the ending time-domain position of PEI-O, and the duration unit of PEI-O can also be referred to as the duration length of PEI-O. There is no specific limitation on this.

[0159] 2) Time unit

[0160] It should be noted that for the time unit, it can be understood as the communication granularity of the terminal or network device in the time domain, that is, the terminal or network device communicates in the time domain with the time unit as the granularity / unit. For example, the time unit can be a frame (such as a radio frame, a system frame, a subframe, a slot, a symbol (such as an OFDM symbol), a mini slot, etc.). There is no specific limitation on this.

[0161] Taking the time unit as a frame as an example, the time unit where PEI-O is located can be PEI-F.

[0162] Taking the time unit as a symbol as an example, the starting time unit of PEI-O can be the starting symbol of PEI-O; the ending time unit of PEI-O is the ending symbol of PEI-O. Similarly, when the time unit is a slot, the starting time unit of PEI-O is the starting slot of PEI-O; the ending time unit of PEI-O is the ending slot of PEI-O.

[0163] Taking the time unit as a symbol as an example, the duration unit of PEI-O can be the number of consecutive symbols of PEI-O. Similarly, when the time unit is a slot, the duration unit of PEI-O is the number of consecutive slots of PEI-O.

[0164] In summary, for how to determine the position of PEI-O, the embodiments of the present application can be implemented through configuration information, that is, the configuration information is used to determine the position of PEI-O.

[0165] In short, the embodiments of the present application need to analyze the starting positions of PEI-F and PEI-O for signaling indication, first indicating PEI-F (coarse granularity), and then indicating the starting position of PEI-O (fine granularity).

[0166] Therefore, in order to determine the position of PEI-O, the embodiments of the present application can determine the position of PEI-F and the starting position of PEI-O according to the configuration information. Specific descriptions will be provided later.

[0167] 3) Configuration information

[0168] It should be noted that the configuration information can be transmitted through high-layer signaling or high-layer parameters during processes such as cell search, cell access, cell residence, random access, initial access, cell reselection, cell handover, and uplink / downlink resource scheduling. It can be specified (defined / specified) by a standard protocol or pre-configured, and no specific restrictions are imposed on this.

[0169] The configuration information can include at least one of PEI_offset, PEI_offset(i_pf), frame_offset, UE_ID, symbol offset, SFN_pei, T, N, N_pei, M, Ns, Nsg, i_pf, i_f, i_s, i_sg, i_pei, etc.

[0170] It should be noted that for the DRX cycle in the embodiments of the present application, if it is configured by RRC and / or high layer, the DRX cycle can be determined by the shortest among the UE specific DRX values. Alternatively, the DRX cycle can be the default DRX value broadcast in the system information. In the RRC_IDLE state, if the UE specific DRX value is not configured by the high layer, the default DRX value is applied.

[0171] An example will be given below taking the terminal and the network device as examples.

[0172] Exemplarily, for the terminal, the terminal can obtain the configuration information and determine the position of PEI-O according to the configuration information.

[0173] Among them, determining the position of PEI-O according to the configuration information can include: determining the position of PEI-F and the starting position of PEI-O according to the configuration information.

[0174] For the network device, the network device can send the configuration information, and the configuration information can be used to determine the position of PEI-O.

[0175] Among them, the configuration information can be used to determine the position of PEI-F and the starting position of PEI-O.

[0176] Combined with the content in the above "1) Position of PEI-O", since the position of PEI-O can include the position of the time unit where PEI-O is located and the position of the starting time unit of PEI-O, the following takes the position of the time unit where PEI-O is located and the position of the starting time unit of PEI-O as examples for specific description respectively.

[0177] 4) How to determine the position of the time unit where PEI-O is located

[0178] It should be noted that the position of PEI-F can be represented by the frame number SFN_pei of PEI-F.

[0179] In "How to determine the time unit where PEI-O is located", the embodiments of the present application take the case where the time unit is a frame as an example for description, and the same applies to other cases. Therefore, the embodiments of the present application can determine the position of PEI-F according to the above configuration information.

[0180] ① Position of PEI-F

[0181] The following uses examples to illustrate how to determine the position of PEI-F according to the above configuration information.

[0182] Example 1:

[0183] Taking the configuration information including PEI_offset as an example, the terminal can determine the position of PEI-F according to this PEI_offset.

[0184] It should be noted that since this PEI_offset can make the offset of PEI-O in T large enough (at the frame level), which is beneficial for the network device to make PEI-O have a flexible position with fewer signaling. That is to say, if there is only symbol offset, to indicate an offset of 1 to 10 frames, 140 to 1400 need to be indicated (assuming one frame has 140 symbols), while if there is frame offset, only 1 to 10 need to be indicated, saving signaling overhead. The combination of PEI_offset and symbol offset can not only save signaling overhead but also finely indicate the starting position. The symbol offset is described later.

[0185] Example 2:

[0186] Taking the configuration information including PEI_offset and UE_ID as an example, the terminal can determine the position of PEI-F according to PEI_offset and UE_ID.

[0187] It should be noted that since the position of PEI-F can be determined by UE_ID, the terminal only needs to listen for PEI-O at the position of PEI-F determined by its own UE_ID, which is beneficial for reducing the terminal complexity and improving the communication efficiency.

[0188] In addition, in the embodiments of the present application, PEI-O may correspond to PO, and PF may include one or more POs. Therefore, the embodiments of the present application need to analyze the following two situations:

[0189] Situation 1: One PEI-O corresponds to a PO (one or more POs) within one PF;

[0190] Situation 2: One PEI-O corresponds to POs (multiple POs) within multiple PFs.

[0191] ② Situation 1

[0192] In "Situation 1", when one PEI-O corresponds to a PO (one or more POs) within one PF, the position of this one PEI-O can be configured before this one or more POs.

[0193] In the embodiments of the present application, "Situation 1" can satisfy the following Condition 1:

[0194] M < Ns or M = Ns;

[0195] Among them, the symbol "<" means less than, and the symbol "=" means equal to.

[0196] It should be noted that since one PEI-O corresponds to a PO within one PF, this M can be the number of POs corresponding to this one PEI-O within this one PF.

[0197] The embodiments of the present application may refer to the above "Condition 1" as the "number of POs condition corresponding to the first PEI", or may refer to the above "Condition 1" by other descriptions, and there is no specific limitation on this.

[0198] In addition, in the embodiments of the present application, "Situation 1" can satisfy the following Condition 2:

[0199] N_pei > N or N_pei = N;

[0200] N_pei = max(1, (Ns / M) * N), or N_pei = (Ns / M) * N;

[0201] Among them, the symbol ">" means greater than, the symbol " / " means division sign (i.e., perform division operation), and the symbol "*" means multiplication sign (i.e., perform multiplication operation).

[0202] It should be noted that since one PEI-O corresponds to POs within multiple PFs, this M can be the number of POs corresponding to this one PEI-O within this multiple PFs.

[0203] In the embodiments of the present application, the above "Condition 2" may be referred to as the "First PEI Number Condition", or the above "Condition 2" may be referred to as other descriptions, and no specific restrictions are imposed thereon.

[0204] ③ Case 2

[0205] In "Case 2", when one PEI-O corresponds to multiple POs within multiple PFs (multiple POs within multiple PFs), the position of this one PEI-O can be configured before these multiple PFs.

[0206] In the embodiments of the present application, "Case 1" may satisfy the following Condition 3:

[0207] M > Ns;

[0208] It should be noted that since one PEI-O corresponds to multiple POs within multiple PFs, this M can be the number of POs corresponding to this one PEI-O within these multiple PFs.

[0209] In the embodiments of the present application, the above "Condition 3" may be referred to as the "PO Number Condition Corresponding to the Second PEI", or the above "Condition 3" may be referred to as other descriptions, and no specific restrictions are imposed thereon.

[0210] In addition, in the embodiments of the present application, "Case 2" may satisfy the following Condition 4:

[0211] N_pei < N;

[0212] N_pei = max(1, (Ns / M) * N), or N_pei = (Ns / M) * N;

[0213] It should be noted that since one PEI-O corresponds to multiple POs within multiple PFs, this M can be the number of POs corresponding to this one PEI-O within these multiple PFs.

[0214] In the embodiments of the present application, the above "Condition 4" may be referred to as the "Second PEI Number Condition", or the above "Condition 4" may be referred to as other descriptions, and no specific restrictions are imposed thereon.

[0215] ④ How to determine the position of PEI-F in Case 1

[0216] It should be noted that for how to determine the position of PEI-F in Case 1, in the embodiments of the present application, the position of PEI-F can be represented by SFN_pei, and SFN_pei can be determined through the above configuration information.

[0217] The following illustrates by way of example how to determine SFN_pei according to the above configuration information.

[0218] Example 1:

[0219] Taking the configuration information including PEI_offset, T, N, and UE_ID as an example, SFN_pei can satisfy the following:

[0220] (SFN_pei + PEI_offset) mod T = (T / N) * (UE_ID mod N);

[0221] Where, mod is the modulo operation or the remainder operation. For example, A mod B represents the remainder obtained when A is divided by B.

[0222] It should be noted that UE_ID can be 5G - S - TMSI mod 1024. SFN_pei is determined by the log2(N) least significant bits (LSBs) of UE_ID (i.e., i_pf = (UE_ID mod N)), and N PFs are evenly distributed within T (i.e., represented by multiplying by T / N), where log2 is the logarithm to the base 2, equivalent to the number of bits (the number of binary digits).

[0223] In addition, using this method needs to meet the PO number condition or the first PEI number condition corresponding to the first PEI in "Case 1".

[0224] Example 2:

[0225] Taking the configuration information including PEI_offset and SFN as an example, SFN_pei can satisfy the following:

[0226] SFN_pei = SFN - PEI_offset;

[0227] It can be seen that the terminal can determine SFN_pei through SFN and PEI_offset, which is easy to implement.

[0228] , SFN_pei needs to meet the PO number condition or the first PEI number condition corresponding to the first PEI in "Case 1".

[0229] ⑤ How to determine the position of PEI - F in Case 2

[0230] It should be noted that for how to determine the position of PEI - F in Case 2, the embodiment of the present application can represent the position of PEI - F by the frame number SFN_pei of PEI - F, and determine SFN_pei through the above - mentioned configuration information.

[0231] The following uses examples to illustrate how to determine SFN_pei according to the above - mentioned configuration information.

[0232] Example 1:

[0233] Taking the configuration information including PEI_offset, N_pei, and i_pei as an example, SFN_pei can satisfy the following:

[0234] (SFN_pei + PEI_offset) mod T = (T / N_pei) * i_pei;

[0235] N_pei = max(1, (Ns / M) * N);

[0236] It can be seen that the embodiment of the present application can determine SFN_pei through N_pei, and N_pei PEIs are evenly dispersed within T (by multiplying by T / N_pei). In addition, the terminal only needs the parameters Ns, M, and N to calculate N_pei, and N_pei cannot be less than 1, that is, the number of PEIs within T cannot be less than 1.

[0237] In addition, SFN_pei needs to satisfy the PO number condition or the second PEI number condition corresponding to the second PEI in "Case 2".

[0238] For i_pei, there can be the following methods:

[0239] Method 1:

[0240] i_pei = floor((UE_ID mod N) / (N / N_pei));

[0241] In this way, i_pei is equivalent to first taking out the log2(N) least significant bits (LSBs) of UE_ID, and then shifting them to the right by log2(N / N_pei) bits.

[0242] For example, when N is 4 and N_pei is 2, i_pei = floor((UE_ID mod 4) / 2), which is equivalent to first taking out the 2 LSBs of UE_ID, and then shifting them to the right by 1 bit, that is, taking out the second LSB from the bottom.

[0243] Method 2:

[0244] i_pei = floor(UE_ID / (N / N_pei)) mod N_pei;

[0245] In this way, i_pei is equivalent to first shifting UE_ID to the right by log2(N / N_pei) bits, and then taking out the log2(N_pei) LSBs.

[0246] For example, when N is 4 and N_pei is 2, i_pei = floor((UE_ID / 2) mod 2), which is equivalent to first shifting UE_ID to the right by 1 bit, and then taking out 1 of the LSBs, that is, taking out the second LSB from the bottom.

[0247] Method 3:

[0248] i_pei = floor(max(UE_ID / N, UE_ID * Ns / M)) mod N_pei;

[0249] In this way, the terminal can calculate i_pei without calculating N_pei. This formula replaces N_pei in Method 2 with N_pei = max(1, (Ns / M) * N), N_pei / N = max(1 / N, Ns / M), UE_ID * N_pei / N = max(UE_ID / N, UE_ID * Ns / M). Or,

[0250] i_pei = floor(UE_ID * Ns / M) mod N_pei

[0251] In this way, the terminal can calculate i_pei without calculating N_pei. This formula replaces N_pei in Method 2 with N_pei = (Ns / M) * N, N_pei / N = Ns / M, UE_ID * N_pei / N = UE_ID * Ns / M.

[0252] Example 2:

[0253] Taking the configuration information including PEI_offset(i_f), frame_offset, SFN, and i_f as an example, SFN_pei can satisfy the following:

[0254] SFN_pei = SFN - PEI_offset(i_f);

[0255] PEI_offset(i_f) = frame_offset + i_f * (T / N);

[0256] Among them, PEI_offset(i_f) is the frame offset related to i_f, SFN is the frame number of the PF of the target PO, and frame_offset is the frame offset unrelated to i_f.

[0257] It can be seen that the terminal can determine SFN_pei through FN and PEI_offset(i_f), which is easy to implement. In addition, through PEI_offset(i_f), there are different frame offsets related to i_f for different PFs.

[0258] It should be noted that SFN_pei needs to meet the PO number condition or the second PEI number condition of "Situation 2".

[0259] Example 3:

[0260] Taking the configuration information including UE_ID, PEI_offset(i_f), T, i_f, N, and frame_offset as an example, SFN_pei can satisfy the following:

[0261] (SFN_pei + PEI_offset(i_f)) mod T = (T / N) * UE_ID mod N;

[0262] PEI_offset(i_f) = frame_offset + i_f * (T / N);

[0263] It can be seen that by using i_f to determine SFN_pei, N PFs are evenly dispersed within T (by multiplying by T / N). Additionally, through PEI_offset(i_f), there are different frame offsets related to i_f for different PFs.

[0264] It should be noted that SFN_pei needs to satisfy the condition of the number of POs corresponding to the second PEI or the condition of the number of the second PEIs in "Case 2".

[0265] 5) How to determine the starting time unit of PEI-O

[0266] In "How to determine the starting time unit of PEI-O", the embodiment of the present application refers to the starting time unit of PEI-O as the starting position of PEI-O. Therefore, the embodiment of the present application can determine the starting position of PEI-O according to the above configuration information.

[0267] ① Starting position of PEI-O

[0268] The following illustrates by way of example how to determine the starting position of PEI-O according to the above configuration information.

[0269] Example 1:

[0270] Taking the configuration information including symbol offset as an example, the terminal can determine the starting position of PEI-O according to this symbol offset.

[0271] Among them, this symbol offset is the symbol offset of the starting position of PEI-O relative to the starting position of PEI-F.

[0272] It should be noted that the starting position of PEI-F can include the first symbol of PEI-F.

[0273] It can be seen that since the symbol offset can enable the PEI-O to have a symbol-level offset within the frame, making the starting position of the PEI-O fine enough, the network device can use this symbol offset to bring the PEI-O closer to the SSB, so that after the mid-terminal finishes processing the SSB (AGC and time-frequency synchronization), it can listen to the PEI PDCCH as soon as possible.

[0274] Example 2:

[0275] Taking the configuration information including the reference time and the offset as an example, the terminal can determine the starting position of the PEI-O according to the reference time and the offset.

[0276] Among them, the reference time can be the starting position of a PO corresponding to the PEI. In this way, the terminal only needs to determine the position of the PEI-O according to the starting position of a PO corresponding to the PEI and the offset, which is easy to implement.

[0277] Among them, the offset can be the PEI_offset, the symbol offset, or the offset of the absolute time. For example, the offset of the absolute time is 0.125 milliseconds.

[0278] Furthermore, a PO corresponding to the PEI can be the first PO within the first PF corresponding to the PEI. In this way, the terminal can default the first PO within the first PF corresponding to the PEI as the starting position, which is easy to implement.

[0279] In the embodiments of the present application, the PEI-O can correspond to a PO, and the PF can contain one or more POs. Therefore, here, the same as in the above “4) How to determine the position of the time unit where the PEI-O is located”, there are two situations, namely Situation 1 and Situation 2, which will not be elaborated here.

[0280] ② How to determine the symbol offset in Example 1 in Situation 1

[0281] It should be noted that for how to determine the symbol offset in Example 1 in Situation 1, the embodiments of the present application can determine the symbol offset according to the symbol offset index, that is, the symbol offset is determined by the symbol offset index.

[0282] Among them, the symbol offset index is equal to foor(i_s / M).

[0283] It can be seen that the network device can configure the starting positions of Ns / M PEI-Os by configuring Ns / M symbol offsets. In other words, there are Ns / M PEI-Os within a PEI-F, and the network device needs to configure Ns / M symbol offsets.

[0284] In addition, the symbol offset index needs to meet the PO number condition or the first PEI number condition in “Situation 1”.

[0285] ③ How to determine the symbol offset in Example 1 under Case 2

[0286] It should be noted that for how to determine the symbol offset in Example 1 under Case 2, the embodiments of the present application can determine the symbol offset according to the symbol offset index, that is, the symbol offset is determined by the symbol offset index.

[0287] Wherein, the symbol offset index is equal to 0.

[0288] It can be seen that since one PEI corresponds to multiple PFs, the network device can configure only one symbol offset to determine the determination position of the one PEI-O. In other words, there is one PEI-O in one PEI-F, and the network device needs to configure one symbol offset.

[0289] In addition, the symbol offset index needs to meet the PO number condition or the second PEI number condition of "Case 2".

[0290] ④ The first PF corresponding to the PEI in Example 2 under Case 1

[0291] It should be noted that for the first PF corresponding to the PEI in Example 2 under Case 1, the embodiments of the present application need to determine the index i_pf_ref of the first PF corresponding to the PEI; wherein, i_pf_ref can satisfy the following:

[0292] i_pf_ref = i_pf;

[0293] It can be seen that the terminal can deduce the index of the first PF corresponding to the PEI according to the index i_pf of the PF of the target PO (i.e., the PO corresponding to its own UE_ID), which is beneficial to easy implementation.

[0294] In addition, i_pf_ref needs to meet the PO number condition or the first PEI number condition of "Case 1".

[0295] ⑤ The first PF corresponding to the PEI in Example 2 under Case 2

[0296] It should be noted that for the first PF corresponding to the PEI in Example 2 under Case 2, the embodiments of the present application need to determine i_pf_ref; wherein, i_pf_ref can satisfy the following:

[0297] i_pf_ref = floor(i_pf / (M / Ns))*M / Ns;

[0298] It can be seen that the terminal can deduce the index of the first PF corresponding to the PEI based on the index i_pf of the PF of the target PO (i.e., the PO corresponding to its own UE_ID), which is conducive to easy implementation.

[0299] It should be noted that i_pf_ref needs to meet the condition of the number of POs corresponding to the second PEI or the condition of the number of the second PEIs in "Case 2".

[0300] ⑥ The first PO in the first PF corresponding to this PEI in Example 2 under Case 1

[0301] It should be noted that for the first PO in the first PF corresponding to this PEI in Example 2 under Case 1, the embodiments of the present application need to determine the index i_s_ref of the first PO in the first PF corresponding to this PEI; where i_s_ref can satisfy the following:

[0302] i_s_ref = floor(i_s / M) * (Ns / M);

[0303] It can be seen that the terminal can deduce the index of the first PO in the first PF corresponding to this PEI based on the index i_s of the target PO (i.e., the PO corresponding to its own UE_ID), which is conducive to easy implementation.

[0304] It should be noted that i_s_ref needs to meet the condition of the number of POs corresponding to the first PEI or the condition of the number of the first PEIs in "Case 1".

[0305] ⑦ The first PO in the first PF corresponding to this PEI in Example 2 under Case 2

[0306] It should be noted that for the first PO in the first PF corresponding to this PEI in Example 2 under Case 2, the embodiments of the present application need to determine i_s_ref; where i_s_ref is 0.

[0307] It can be seen that the terminal can default the index of the first PO in the first PF corresponding to this PEI to 0, which is conducive to reducing complexity and easy implementation.

[0308] It should be noted that i_s_ref needs to meet the condition of the number of POs corresponding to the second PEI or the condition of the number of the second PEIs in "Case 2".

[0309] 6) How to distinguish between Case 1 and Case 2

[0310] Combined with the content in the above "4) How to determine the position of the time unit where PEI - O is located", it can be seen that the embodiments of the present application need to analyze Case 1 and Case 2.

[0311] That is, determine that one PEI-O corresponds to a PO within one PF, or determine that one PEI-O corresponds to multiple POs within multiple PFs.

[0312] Therefore, in order to distinguish between Case 1 and Case 2 and implement the design of the PEI, the embodiments of the present application can be distinguished according to the above configuration information.

[0313] The following uses a terminal and a network device as examples for illustration.

[0314] Exemplarily, for a terminal, the terminal can obtain the configuration information and determine that one PEI-O corresponds to a PO within one paging frame PF (i.e., "Case 1") according to the configuration information; or determine that one PEI-O corresponds to multiple POs within multiple PFs (i.e., "Case 2") according to the configuration information.

[0315] For a network device, the network device can send the configuration information, and the configuration information is used to determine that one PEI-O corresponds to a PO within one paging frame PF or one PEI-O corresponds to multiple POs within multiple PFs.

[0316] The following uses an example to illustrate how to make a determination according to the above configuration information.

[0317] Example 1:

[0318] In some possible examples, determining that one PEI-O corresponds to a PO within one paging frame PF may include: if the condition of the number of POs corresponding to the first PEI or the condition of the number of the first PEIs is satisfied, then determine that one PEI-O corresponds to a PO within one PF.

[0319] Among them, the condition of the number of POs corresponding to the first PEI is determined by the configuration information, and the condition of the number of the first PEIs is determined by the configuration information.

[0320] It should be noted that for the explanations of the "condition of the number of POs corresponding to the first PEI" and the "condition of the number of the first PEIs", please refer to the content in the above "② Case 1", and details are not described herein again.

[0321] Example 2:

[0322] In some possible examples, determining that one PEI-O corresponds to multiple POs within multiple PFs may include: if the condition of the number of POs corresponding to the second PEI or the condition of the number of the second PEIs is satisfied, then determine that one PEI-O corresponds to multiple POs within multiple PFs.

[0323] Among them, the condition of the number of POs corresponding to the second PEI is determined by the configuration information, and the condition of the number of the second PEIs is determined by the configuration information.

[0324] It should be noted that for the explanations of the "number of POs corresponding to the second PEI" and the "number of second PEIs", please refer to the content in the above "③ Case 2", and no further elaboration will be provided here.

[0325] In summary, in order to determine the position of PEI-O, the embodiments of the present application can confirm the position of PEI-F (coarse-grained) and the starting position of PEI-O (fine-grained).

[0326] Combining the content in the above "① Position of PEI-F" and "① Starting position of PEI-O", it can be known that in order to determine the position of PEI-O, the embodiments of the present application can have the following example methods:

[0327] Example 1:

[0328] Taking the configuration information including PEI_offset and symbol offset as an example, determining the position of PEI-O according to the configuration information includes: determining the position of PEI-F according to the PEI_offset, and determining the starting position of PEI-O according to the symbol offset.

[0329] Example 2:

[0330] Taking the configuration information including PEI_offset, UE_ID and symbol offset as an example, determining the position of PEI-O according to the configuration information includes: determining the position of PEI-F according to PEI_offset and UE_ID, and determining the starting position of PEI-O according to the symbol offset.

[0331] Example 3:

[0332] Taking the configuration information including PEI_offset, reference time and offset as an example, determining the position of PEI-O according to the configuration information includes: determining the position of PEI-F according to the PEI_offset, and determining the starting position of PEI-O according to the reference time and the offset.

[0333] Example 4:

[0334] Taking the configuration information including PEI_offset, UE_ID, reference time and offset as an example, determining the position of PEI-O according to the configuration information includes: determining the position of PEI-F according to PEI_offset and UE_ID, and determining the starting position of PEI-O according to the reference time and the offset.

[0335] 2. How to determine the number of bits of PEI PDCCH

[0336] It should be noted that the explanations of some concepts required here can be the same as those in "1. How to Determine the Position of PEI-O" above, such as configuration information, Case 1, Case 2, etc., and will not be elaborated here.

[0337] In addition, the number of bits of the PDCCH is the number of bits of the DCI in the PDCCH or the DCI format corresponding to the PDCCH. The terminal needs to know in advance the number of bits of the DCI in the PDCCH or the DCI format corresponding to the PDCCH to decode the DCI in the PDCCH.

[0338] The following takes the terminal and the network device as examples for illustration.

[0339] Exemplarily, for the terminal, the terminal can obtain the configuration information and determine the number of bits of the PEI PDCCH according to the configuration information.

[0340] For the network device, the network device can send the configuration information, which is used to determine the number of bits of the PEI PDCCH.

[0341] The following illustrates by way of example how to determine the number of bits of the PEI PDCCH according to the configuration information.

[0342] Example 1:

[0343] Taking the configuration information including at least one of Nsg, M, Y, N, N_pei, and Ns as an example,

[0344] Determine that the number of bits of the PEI PDCCH is Nsg * M; or,

[0345] Determine that the number of bits of the PEI PDCCH is Y + Nsg * M; or,

[0346] Determine that the number of bits of the PEI PDCCH is Nsg * Ns * (N / N_pei); or,

[0347] Determine that the number of bits of the PEI PDCCH is Y + Nsg * Ns * (N / N_pei);

[0348] It should be noted that for the "subgroups within the PO", see the content in "5. PEI Group, PF Group, PO Group, Subgroups within the PO" above, and will not be elaborated here.

[0349] It can be seen that if the terminal determines that one PEI-O corresponds to one or more POs within a PF, and there are Nsg subgroups within one PO, then the number of bits of the PEI-PDCCH can be determined as Nsg * M.

[0350] If the terminal determines that one PEI-O corresponds to multiple POs within one PF, and one PEI corresponds to N / N_pei PFs, there are Ns POs within one PF, and there are Nsg subgroups within one PO, then the number of bits of the PEI-PDCCH can be determined as Nsg * Ns * (N / N_pei).

[0351] The reason for adding Y is that the first indication information is common information, such as information related to short messages and information on the availability of Tracking Reference Signals (TRS).

[0352] Example 2:

[0353] Taking the configuration information including Nsg, Y, and M as an example,

[0354] If the condition of the number of POs corresponding to the first PEI or the condition of the number of the first PEI is satisfied, then the number of bits of the PEI PDCCH is determined as Nsg * M; or,

[0355] If the condition of the number of POs corresponding to the first PEI or the condition of the number of the first PEI is satisfied, then the number of bits of the PEI PDCCH is determined as Y + Nsg * M;

[0356] It should be noted that for the explanations of "the condition of the number of POs corresponding to the first PEI" and "the condition of the number of the first PEI", please refer to the content in "② Case 1" above, and no further elaboration will be provided here.

[0357] For "subgroups within a PO", please refer to the content in "5. PEI group, PF group, PO group, subgroups within a PO" above.

[0358] It can be seen that in "Case 1", since one PEI-O corresponds to a PO within one PF, and there are Nsg subgroups within one PO, the number of bits of the PEI-PDCCH can be determined as Nsg * M.

[0359] In addition, the reason for adding Y is that the first indication information is common information, such as information related to short messages and information on the availability of tracking reference signals.

[0360] Example 3:

[0361] Taking the configuration information including Nsg, Y, M, N_pei, Ns, and N as an example,

[0362] If the condition of the number of POs corresponding to the second PEI or the condition of the number of the second PEI is satisfied, then the number of bits of the PEI PDCCH is determined as Nsg * Ns * (N / N_pei); or,

[0363] If the condition of the number of POs corresponding to the second PEI or the condition of the number of the second PEIs is satisfied, determine that the number of bits of the PEI PDCCH is Y + Nsg * Ns * (N / N_pei);

[0364] It should be noted that for the explanations of the "condition of the number of POs corresponding to the second PEI" and the "condition of the number of the second PEIs", please refer to the content in the above "③ Case 2", and details will not be repeated here.

[0365] For the "sub - group within the PO", please refer to the content in the above "5. PEI group, PF group, PO group, sub - group within the PO".

[0366] It can be seen that in "Case 2", since one PEI - O corresponds to multiple POs within a PF, and one PEI corresponds to N / N_pei PFs, there are Ns POs within one PF, and there are Nsg sub - groups within one PO, so the number of bits of the PEI - PDCCH can be determined as Nsg * Ns * (N / N_pei).

[0367] In addition, the reason for adding Y is that the first indication information is public information, such as information related to short messages and information on the availability of tracking reference signals.

[0368] 3. How to determine the bit position of the terminal group (UE group) within the PEI PDCCH

[0369] It should be noted that the explanations of some concepts required here can be the same as those in the above "1. How to determine the position of the PEI - O", such as configuration information, Case 1, Case 2, etc., and details will not be repeated here.

[0370] In addition, the terminal group (UE group) can include sub - groups within the PO. Among them, for the explanation of the sub - groups within the PO, please refer to the content in the above "5. PEI group, PF group, PO group, sub - groups within the PO", and details will not be repeated here.

[0371] The following takes the terminal and the network device as examples for illustration.

[0372] Exemplarily, for the terminal, the terminal can obtain the configuration information and determine the bit position of the sub - group within the PO within the PEI PDCCH according to this configuration information.

[0373] For the network device, the network device can send the configuration information, and this configuration information is used to determine the bit position of the sub - group within the PO within the PEI PDCCH.

[0374] The following takes an example to illustrate how to determine the bit position of the sub - group within the PO within the PEI PDCCH according to this configuration information.

[0375] Example 1:

[0376] Taking the configuration information including at least one of Nsg, i_s, i_sg, Ns, N, i_f, and Y as an example,

[0377] Determine that the bit position of the subgroup within the PO in the PEI PDCCH is Nsg * i_s + i_sg; or,

[0378] Determine that the bit position of the subgroup within the PO in the PEI PDCCH is Y + Nsg * i_s + i_sg; or,

[0379] Determine that the bit position of the UE subgroup within the PO in the PEI PDCCH is Ns * Nsg * i_f + Nsg * i_s + i_s; or,

[0380] Determine that the bit position of the UE subgroup within the PO in the PEI PDCCH is Y + Ns * Nsg * i_f + Nsg * i_s + i_sg;

[0381] It can be seen that if the terminal determines that one PEI - O corresponds to a PO within a PF, and i_s is the index of the PO, and i_sg is the index of the subgroup within the PO, then the bit position of the UE subgroup within the PO in the PEI PDCCH can be determined as Nsg * i_s + i_sg.

[0382] If the terminal determines that one PEI - O corresponds to multiple POs within a PF, and there are Ns POs within a PF and Nsg subgroups within a PO, and i_s is the index of the PO group and i_sg is the index of the subgroup within the PO, then the bit position of the UE subgroup within the PO in the PEI PDCCH can be determined as Ns * Nsg * i_f + Nsg * i_s + i_sg.

[0383] In addition, the reason for adding Y is that the first indication information is common information, such as information related to short messages and information on the availability of tracking reference signals.

[0384] Furthermore, in Example 1, i_f can satisfy the following:

[0385] i_f = UE_ID mod (N / N_pei)

[0386] It can be seen that i_f is equivalent to taking out log2(N / N_pei) LSBs of UE_ID. For example, when N is 4 and N_pei is 2, i_f = UE_ID mod 2, which is equivalent to taking out 1 LSB of UE_ID, i.e., the least significant bit.

[0387] Furthermore, in Example 1, i_sg can satisfy the following:

[0388] i_sg = floor(UE_ID / N * Ns) mod Nsg;

[0389] It can be seen that i_sg is equivalent to first shifting UE_ID to the right by log2(N * Ns) bits and then taking out log2(Nsg) LSBs. For example, when N is 4, Ns is 2, and Nsg = 2, i_sg = floor(UE_ID / 8) mod 2, which is equivalent to first shifting UE_ID to the right by 3 bits and then taking out 1 LSB, that is, the fourth LSB from the bottom.

[0390] Furthermore, in Example 1, i_s can satisfy the following:

[0391] i_s = floor(UE_ID / N) mod Ns;

[0392] It can be seen that i_s is equivalent to first shifting UE_ID to the right by log2(N) bits and then taking out log2(Ns) LSBs. For example, when N is 4 and Ns is 2, i_s = floor(UE_ID / 4) mod 2, which is equivalent to first shifting UE_ID to the right by 2 bits and then taking out 1 LSB, that is, the third LSB from the bottom.

[0393] Example 2:

[0394] Taking the configuration information including Nsg, i_s, i_sg, and Y as an example,

[0395] If the condition of the number of POs corresponding to the first PEI or the condition of the number of the first PEIs is satisfied, then determine that the bit position of the subgroup within the PO in the PEI PDCCH is Nsg * i_s + i_sg; or,

[0396] If the condition of the number of POs corresponding to the first PEI or the condition of the number of the first PEIs is satisfied, then determine that the bit position of the subgroup within the PO in the PEI PDCCH is Y + Nsg * i_s + i_sg;

[0397] It can be seen that in "Case 1", since one PEI - O corresponds to a PO within a PF, and i_s is the index of the PO and i_sg is the index of the subgroup within the PO, then the bit position of the UE subgroup within the PO in the PEI PDCCH can be determined as Nsg * i_s + i_sg.

[0398] In addition, the reason for adding Y is that the first indication information is common information, such as information related to short messages and information on the availability of tracking reference signals.

[0399] Furthermore, in Example 2, i_sg can satisfy the following:

[0400] i_sg = floor(UE_ID / N * Ns) mod Nsg;

[0401] It can be seen that i_sg is equivalent to first shifting UE_ID to the right by log2(N * Ns) bits and then taking out log2(Nsg) LSBs among them. For example, when N is 4, Ns is 2, and Nsg = 2, i_sg = floor(UE_ID / 8) mod 2, which is equivalent to first shifting UE_ID to the right by 3 bits and then taking out 1 LSB among them, that is, the fourth LSB from the bottom.

[0402] Furthermore, in Example 2, i_s can satisfy the following:

[0403] i_s = floor(UE_ID / N) mod Ns;

[0404] It can be seen that i_s is equivalent to first shifting UE_ID to the right by log2(N) bits and then taking out log2(Ns) LSBs among them. For example, when N is 4 and Ns is 2, i_s = floor(UE_ID / 4) mod 2, which is equivalent to first shifting UE_ID to the right by 2 bits and then taking out 1 LSB among them, that is, the third LSB from the bottom.

[0405] Example 3:

[0406] Taking the configuration information including at least one of Nsg, i_s, i_sg, Ns, i_f, Y, and N as an example,

[0407] If the condition of the number of POs corresponding to the second PEI or the condition of the number of the second PEI is satisfied, then it is determined that the bit position of the UE subgroup in the PEI PDCCH within the PO is Ns * Nsg * i_f + Nsg * i_s + i_s; or,

[0408] If the condition of the number of POs corresponding to the second PEI or the condition of the number of the second PEI is satisfied, then it is determined that the bit position of the UE subgroup in the PEI PDCCH is Y + Ns * Nsg * i_f + Nsg * i_s + i_sg;

[0409] It can be seen that in "Case 2", since one PEI - O corresponds to multiple POs within a PF, and there are Ns POs within a PF and Nsg subgroups within a PO, i_s is the index of the PO group and i_sg is the index of the subgroup within the PO, then the bit position of the UE subgroup in the PEI PDCCH within the PO can be determined as Ns * Nsg * i_f + Nsg * i_s + i_sg.

[0410] In addition, the reason for adding Y is that the first indication information is common information, such as information related to short messages and information on the availability of tracking reference signals.

[0411] Further, in Example 3, i_f can satisfy the following:

[0412] i_f = UE_ID mod (N / N_pei)

[0413] It can be seen that i_f is equivalent to taking out log2(N / N_pei) least significant bits (LSBs) of UE_ID. For example, when N is 4 and N_pei is 2, i_f = UE_ID mod 2, which is equivalent to taking out 1 LSB of UE_ID, i.e., the least significant bit.

[0414] Further, in Example 3, i_sg can satisfy the following:

[0415] i_sg = floor(UE_ID / N*Ns) mod Nsg;

[0416] It can be seen that i_sg is equivalent to first shifting UE_ID to the right by log2(N*Ns) bits and then taking out log2(Nsg) LSBs. For example, when N is 4, Ns is 2, and Nsg = 2, i_sg = floor(UE_ID / 8) mod 2, which is equivalent to first shifting UE_ID to the right by 3 bits and then taking out 1 LSB, i.e., the fourth least significant bit from the right.

[0417] Further, in Example 3, i_s can satisfy the following:

[0418] i_s = floor(UE_ID / N) mod Ns;

[0419] It can be seen that i_s is equivalent to first shifting UE_ID to the right by log2(N) bits and then taking out log2(Ns) LSBs. For example, when N is 4 and Ns is 2, i_s = floor(UE_ID / 4) mod 2, which is equivalent to first shifting UE_ID to the right by 2 bits and then taking out 1 LSB, i.e., the third least significant bit from the right.

[0420] In summary, taking the determination of the position of PEI-O by the terminal as an example, a paging early indication method according to an embodiment of the present application will be introduced by way of example.

[0442] In the case of adopting an integrated unit, Figure 6 it is a block diagram of the functional units of a device for paging early indication according to an embodiment of the present application. The device 600 for paging early indication includes: a determination unit 601.

[0448] In specific implementation, the determination unit 601 is used to execute any step in the above method embodiments, and when performing data transmission such as sending, it can optionally call the acquisition unit to complete the corresponding operations. The following is a detailed description.

[0449] The determination unit 601 is used to determine the position of the paging early indication opportunity PEI-O.

[0450] It should be noted that Figure 6 For the specific implementation of each operation in the above embodiments, reference may be made to the description in the above method embodiments shown, and details will not be repeated here.

[0451] Specifically, in terms of determining the position of the PEI-O, the determination unit 601 is used to:

[0452] Determine the position of the frame PEI-F of the PEI-O according to the frame offset.

[0453] Specifically, in determining the position of PEI-F according to the frame offset, the determining unit 601 is configured to:

[0454] Determine the position of PEI-F according to the frame offset and the terminal identifier UE_ID.

[0455] Specifically, the system frame number SFN_pei of PEI-F is determined by at least one of the frame offset PEI_offset, the discontinuous reception DRX period T, the number N of paging frames PF within T, the system frame number SFN of the PF of the target paging occasion PO, the number N_pei of PEIs within T, the index i_pei of the target PO's PEI within T, the number Ns of POs within the PF, the number M of POs corresponding to the PEI, and the index i_f of the PF of the target PO within the PEI. Specifically, SFN_pei satisfies the following:

[0456] (SFN_pei + PEI_offset) mod T = (T / N) * (UE_ID mod N);

[0457] Where, mod is the modulo operation.

[0458] Specifically, the system frame number SFN_pei of PEI-F is determined by the system frame number SFN of the PF of the target paging occasion PO and the frame offset PEI_offset.

[0459] Specifically, SFN_pei satisfies the following:

[0460] SFN_pei = SFN - PEI_offset.

[0461] Specifically, SFN_pei satisfies the number condition of POs corresponding to the first PEI or the first PEI number condition.

[0462] Specifically, the system frame number SFN_pei of PEI-F is determined by at least one of the frame offset PEI_offset, the DRX period T, the number N_pei of PEIs within the T, and the index i_pei of the target PO's PEI within the T.

[0463] Specifically, SFN_pei satisfies the following:

[0464] (SFN_pei + PEI_offset) mod T = (T / N_pei) * i_pei

[0465] Specifically, i_pei satisfies the following:

[0466] i_pei is equal to floor((UE_ID mod N) / (N / N_pei)); or,

[0467] i_pei is equal to floor(UE_ID / (N / N_pei)) mod N_pei; or,

[0468] i_pei is equal to floor(max(UE_ID / N, UE_ID*Ns / M)) mod N_pei.

[0469] Specifically, N_pei satisfies the following:

[0470] N_pei is equal to max(1, (Ns / M)*N).

[0471] Specifically, the frame number SFN_pei of PEI-F is determined by the frame number SFN of the PF of the target paging occasion PO, the index i_f of the PF of the target PO within the PEI, and the frame offset PEI_offset(i_f) related to i_f.

[0472] Specifically, SFN_pei satisfies the following:

[0473] SFN_pei = SFN - PEI_offset(i_f).

[0474] Specifically, the frame number SFN_pei of PEI-F is determined by at least one of the UE_ID, the DXR period T, the number N of PFs within the T, the index i_f of the PF of the target PO within the PEI, and the frame offset PEI_offset(i_f) related to the i_f.

[0475] Specifically, SFN_pei satisfies the following:

[0476] (SFN_pei + PEI_offset(i_f)) mod T = (T / N)*UE_ID mod N.

[0477] Specifically, SFN_pei satisfies the condition of the number of POs corresponding to the second PEI or the condition of the number of the second PEIs.

[0478] Specifically, PEI_offset(i_f) satisfies the following:

[0479] PEI_offset(i_f) is equal to frame_offset + i_f*(T / N);

[0480] where frame_offset is the frame offset independent of i_f.

[0481] Specifically, in terms of determining the position of PEI-O, the determining unit 601:

[0482] Determine the starting position of PEI-O according to the symbol offset, where the symbol offset is the symbol offset of the starting position of PEI-O relative to the starting position of PEI-F.

[0483] Specifically, the symbol offset is determined by the symbol offset index.

[0484] Specifically, the symbol offset index is equal to floor(i_s / M);

[0485] i_s is the index of the target PO within PF, and M is the number of POs corresponding to PEI.

[0486] Specifically, the symbol offset index is 0.

[0487] Specifically, in determining the position of the paging early indication occasion PEI-O, the determination unit 601 is used for:

[0488] Determine the starting position of PEI-O according to the reference time and the offset.
