[Technical field]

The present application relates to the field of communication technology, and in particular to a paging indication method, an apparatus, a terminal and a readable storage medium. [Background technology]
[0002] In a mobile communication system, a user equipment (UE), also called a terminal, establishes a business connection by periodically monitoring paging messages. In each paging period, the terminal calculates a resource location corresponding to its paging occasion, and can detect whether a paging physical downlink control channel (PDCCH) scrambled by a paging radio network temporary identity (P-RNTI) exists on this paging occasion (PO). If a paging PDCCH is detected, the terminal decodes a corresponding scheduled physical downlink shared channel (PDSCH) to obtain a paging message therein.
[0003] In the related technology, by receiving a paging early indication transmitted by the network side, it is possible to early determine whether paging monitoring is required in the related PO, thereby reducing power consumption for measurement and paging PDCCH demodulation. However, at the same time, the transmission of the paging early indication causes a large amount of network overhead, leading to problems such as reduced reliability of paging PDCCH / PDSCH detection and demodulation.

Effect of the Invention
[0010] In an embodiment of the present application, a terminal obtains paging early indication information (PEI) for indicating a first content, and determines the first content according to the paging early indication information, where the first content includes at least one of monitoring behaviors in N paging occasions after the paging early indication information, first configuration information related to the N paging occasions, and availability of a first signal, where N is a positive integer equal to or greater than 1.

[0013] In order to make the above objectives, features and advantages of the present application more clearly understandable, the present application will be described in more detail below in conjunction with the drawings and the detailed description of the present application. It should be noted that, unless there is a conflict, the features in the embodiments and the embodiments of the present application can be combined with each other.
[0014] In order to facilitate a thorough understanding of the present application, more specific details are described in the following description; however, the present application may be implemented in other ways different from those described herein, and therefore the scope of protection of the present application is not limited to the specific embodiments disclosed below.
[0015] Hereinafter, several embodiment paging indication methods, paging indication devices, terminals and readable storage media according to the present application will be described with reference to Figs. 1 to 8 .
[0016] In one embodiment of the present application, FIG. 1 shows one of the flowcharts of a paging indication method of the embodiment of the present application, which includes the following steps:
[0017] Step 102, obtain paging early indication information.
[0018] Step 104: determining a first content based on the paging early indication information.
[0019] Here, the first content includes at least one of monitoring actions for N paging occasions after the paging early indication information, first configuration information related to the N paging occasions, and availability of the first signal, and the value of N is a positive integer greater than or equal to 1 and less than the maximum number of paging occasions configured in the PF.
[0020] In this embodiment, the terminal determines monitoring behaviors in N paging occasions according to the paging early indication information sent by the network side, and does not need to indicate whether monitoring is required by one paging early indication information before each paging occasion, and further reduces network overhead caused by sending paging early indication information. In addition, the paging early indication information can also determine whether the first configuration information and / or the first signal related to the N paging occasions are available, thereby ensuring the demodulation and detection reliability of the paging physical downlink control channel (paging PDCCH) and the paging physical downlink shared channel (paging PDSCH), and further enabling the terminal to achieve both energy saving and performance overhead.
[0021] It should be noted that a paging occasion (PO) is a set of monitoring occasions (MOs) of a paging PDCCH and may consist of multiple slots. Each terminal (UE) only needs to detect one paging occasion associated with it in one paging cycle (DRX cycle). The network configures an idle UE to be uniformly assigned to multiple POs according to terminal identity information. The UE can know the PO in which it is located based on a protocol agreement. The first signal is a TRS / CSI-RS reference signal, where the configuration information of the TRS / CSI-RS reference signal may be configured by a system message.
[0022] Furthermore, the N paging occasions may be N consecutive paging occasions or N non-consecutive paging occasions.
[0023] In the above embodiment, the paging early indication information is used to inform the UE whether it needs to monitor a subsequent PO, thereby saving the power consumption required to receive one or more SSBs based on the channel quality before monitoring the PO and perform synchronization channel measurements, etc., thereby achieving energy saving for the terminal; and by indicating one or more next paging occasions using one paging early indication information according to this embodiment, network overhead is reduced, thereby achieving both network overhead and terminal energy saving.
[0024] Further, in one embodiment of the present application, each paging occasion of the N paging occasions is associated with W paging groups, where W is a positive integer greater than or equal to 1.
[0025] In this embodiment, different UEs may be assigned to the same PO, i.e., multiple UEs may be associated with the same PO. In order to further reduce the probability of false awakening between multiple UEs in the same PO, the UEs associated with each PO among the N POs may be further divided into W paging groups, i.e., the N POs are divided into a total of N×W paging groups, where W is the number of paging groups into which the UEs associated with one PO are divided.
[0026] It should be noted that if W is 1, the UE associated with the PO has only one paging group, i.e., the PO is not packetized.
[0027] In this embodiment, the PO is further packetized to reduce the probability that the terminal is falsely awakened by the network, and further save the energy consumption of the terminal.
[0028] In one embodiment of the present application, the monitoring action further includes at least one of whether to monitor a paging PDCCH of a paging group associated with the terminal, whether to monitor paging of a paging group associated with the terminal, and whether to monitor system information updates of a paging group associated with the terminal.
[0029] Here, the paging group associated with the terminal is at least one of the paging groups associated with at least one paging occasion among the N paging occasions.
[0030] It should be noted that a paging occasion associated with a terminal is one (or more) of N paging occasions, and if there are W paging groups in the paging occasion associated with the terminal, the terminal is further assigned to one (or more) of the W paging groups, that is, the number of paging groups associated with a terminal may be one or more.
[0031] In this embodiment, if the paging early indication information acquired by the terminal indicates that it needs to monitor the paging physical downlink control channel (paging PDCCH), the terminal blindly detects the physical downlink control channel PDCCH scrambled by the paging-radio network temporary identifier (P-RNTI), and if the terminal detects this paging PDCCH, it further receives and decodes the scheduled physical downlink shared channel (PDSCH) according to the downlink control information DCI (Downlink Control Information) in the PDCCH, and if the terminal does not detect the paging PDCCH, it considers that there is no paging message for itself and enters a corresponding sleep state according to the paging cycle. If the paging early indication information received by the terminal indicates that it does not need to monitor the paging physical downlink control channel, it does not monitor the subsequent paging PDCCH and enters a corresponding sleep state according to the paging cycle. Similarly, if the paging early indication information received by the terminal indicates that it needs to monitor paging and / or system information update, it receives the corresponding paging and / or ETWS and CMAS, etc.
[0032] It should be noted that when W=1, i.e., PO is not packetized, then there is no need to perform a monitoring action for each paging group, i.e., the monitoring action includes at least one of whether to monitor a paging physical downlink control channel in a paging occasion associated with the terminal, whether to monitor paging in a paging occasion associated with the terminal, and whether to monitor system information update in a paging occasion associated with the terminal.
[0033] In one embodiment of the present application, the first configuration information further includes at least one of a minimum time interval between the paging early indication information and a first paging occasion of the N paging occasions, a value of N, and an index of the N paging occasions.
[0034] In this embodiment, the network may configure the indexes of all paging occasions in each paging cycle, and the paging early indication information dynamically indicates the indexes of the indicated N paging occasions, thereby determining the indicated N paging occasions. The first paging occasion may be any one of the N paging occasions.
[0035] Specifically, the first paging occasion may be a paging occasion that is closest to the paging early indication information associated therewith among the N paging occasions, i.e., the first paging occasion may be the earliest (or first) paging occasion among the N paging occasions. Note that the first paging occasion may also be the latest paging occasion, and is not limited thereto.
[0036] In one embodiment, the value of N is related to the number of paging occasions configured in one paging frame PF. The indication relationship between the paging early indication information and the subsequent N paging occasions is determined by the first configuration information, and the minimum time interval between the paging early indication information and the first paging occasion among the N paging occasions is satisfied, thereby realizing dynamic and flexible indication of the N paging occasions, and reducing the network overhead caused by the transmission of the paging early indication information. In addition, by leaving a sufficient time distance between the paging early indication information and the indicated N paging occasions, the measurement of the related reference signal can be performed, and the reliability of the demodulation and detection of the paging physical downlink control channel and the paging physical downlink shared channel is guaranteed, so as to achieve both energy saving and performance overhead of the terminal.
[0037] Specifically, for example, the terminal receives paging early indication information, where the paging early indication information indicates related to N subsequent paging occasions PO, and includes at least one of the following:
[0038] 1. Non-common information, ie, the necessary information that is composed solely for different POs, the non-common information includes monitoring actions in the N POs following the paging early indication information.
[0039] The monitoring action includes whether to monitor a paging PDCCH on a PO associated with the terminal, where the paging PDCCH includes paging and system message update indications, such as whether to monitor paging on a PO associated with the terminal, and whether to monitor system message updates on a PO associated with the terminal.
[0040] Specifically, the PO associated with the terminal is at least one of the N POs. If the paging early indication information also indicates a paging packet of the paging occasion, the terminal is associated with at least one paging group in at least one of the N POs. Monitoring act includes whether to monitor a paging PDCCH of a paging group associated with the terminal, whether to monitor paging of a paging group associated with the terminal, and whether to monitor a system information update of a paging group associated with the terminal.
[0041] 2. Common information, that is, information that can be unifiedly configured by N POs, and the common information includes the following:
[0042] (1) Whether or not TRS / CSI-RS is available. Configuration information for TRS / CSI-RS may be configured by a system message.
[0043] (2) The value of N may be 4 if one PF includes four POs.
[0044] (3) The number W of paging groups divided on one PO, for example W=4.
[0045] (4) As shown in Figure 4, the minimum time interval between the paging early indication information and the N subsequent associated POs may be three SSB periods, where the SSB period is 20s, and the minimum time interval must be at least 60ms or more. The minimum time interval may be 60ms, 80ms, or 120ms.
[0046] (5) Indicating the N POs based on the indexes of the N POs indicated by the paging early indication information.
[0047] In one embodiment of the present application, FIG. 2 shows a second flowchart of the paging indication method of the embodiment of the present application, and the paging indication method further includes the following steps:
[0048] Step 202, obtaining second configuration information; Here, the second configuration information is configured by the network side and / or agreed upon by a protocol.
[0049] Further, the second configuration information includes at least one of a minimum time interval between the paging early indication information and a second paging occasion among the N paging occasions, a time domain location of the paging early indication information, a frequency domain location of the paging early indication information, a value of N, candidate values of N, a value of the number of paging groups W associated with the paging occasion, and an indication relationship between the paging early indication information and the N paging occasions.
[0050] Specifically, similar to the first paging occasion, the second paging occasion may be any one of the N paging occasions. Specifically, the second paging occasion may be a paging occasion that is closest to the paging early indication information associated therewith among the N paging occasions, that is, the second paging occasion may be the earliest (or called the first) paging occasion among the N paging occasions. Note that the second paging occasion may also be the latest paging occasion, and is not limited thereto.
[0051] Here, different UEs may be assigned to the same PO, i.e., multiple UEs may be associated with the same PO. In order to further reduce the probability of false awakening among multiple UEs in the same PO, the UEs associated with each PO among the N POs may be further divided into W paging groups, i.e., the N POs are divided into a total of N×W paging groups, where W is the number of paging groups into which the UEs associated with one PO are divided.
[0052] Step 204: determining a first content based on the second configuration information and the paging early indication information.
[0053] As can be understood, the second configuration information may be obtained by configuration and / or protocol agreement by the network side before obtaining the paging early indication information.
[0054] In one embodiment of the present application, specifically, the network side configures (1) the minimum time interval between the paging early indication information and the second paging occasion of the N paging occasions, (2) the time domain location of the paging early indication information, (3) the frequency domain location of the paging early indication information, (4) the value of N (N is the number of POs indicated by one paging early indication information), and (5) the value of W (the number of paging groups divided within one PO).
[0055] In one embodiment, the network side may broadcast the second configuration information (1)-(5) to the terminal in a message such as System Information 1 (SIB1), Master Information Block (MIB), or PBCH, etc. In addition, the indication relationship between the paging early indication information and the N paging occasions may be determined by a protocol.
[0056] In this embodiment, the terminal does not instruct by a single paging early indication information before each paging occasion, but receives second configuration information and paging early indication information to determine monitoring behaviors for N paging occasions and availability of first configuration information and / or first signals related to the N paging occasions, thereby reducing network overhead caused by transmitting paging early indication information and ensuring reliability of demodulation and detection of the paging physical downlink control channel and the paging physical downlink shared channel.
[0057] As can be understood, the terminal may obtain the first configuration information through the paging early indication information, or may obtain the first configuration information through the second configuration information, where the first configuration information and the second configuration information are partially the same, for example, the minimum time interval between the paging early indication information and the N paging occasions, the value of N is the same, and when the content of the configuration obtained by the terminal from the second configuration information and the same configuration obtained from the paging early indication information are inconsistent, the paging early indication information at this time is equivalent to updating the inconsistent configuration according to the conflicting configuration indicated by the paging early indication information. For example, if the second configuration information indicates that the minimum time interval is 60 ms, but the paging early indication information indicates that the minimum time interval is 80 ms, the terminal performs a monitoring operation at the subsequent paging occasion with the minimum time interval of 80 ms. Here, the candidate value of N refers to that the network side can configure various candidate values of N, for example, N=1, 2, 4, 8. Then, the value of N is further determined by obtaining a paging early indication message, for example, the paging early indication message indicates that the value of N is 4.
[0058] In one embodiment of the present application, the minimum time interval must further satisfy at least one of the following:
[0059] (1) The minimum time interval must be at least K transmission periods of synchronization signal blocks, where K is a positive integer equal to or greater than 0. As can be understood, the transmission period of a synchronization signal block is the reception period of a synchronization signal block. For example, if there are two transmission periods between three synchronization signal blocks (SSB) and the transmission period is configured by the network side to be 20 ms, the minimum time interval must be at least greater than 40 ms.
[0060] (2) The minimum time interval is related to at least one of the channel quality of the serving cell, the signal strength, the coverage performance, the terminal location, and the terminal movement rate.
[0061] To give a specific example, the minimum time interval is related to the channel quality of the serving cell, and the network equipment configures multiple minimum time intervals, and the terminal side selects the corresponding minimum time interval based on the channel quality measured by itself. For example, when the signal-to-noise ratio (SNR) is -6 dB, the channel quality at this time is relatively poor, and the corresponding minimum time interval satisfies the transmission period of three or more SSBs; when the SNR is 0 dB, the channel quality at this time is relatively good, and the corresponding minimum time interval satisfies the transmission period of one or more SSBs.
[0062] In addition, in another embodiment, the minimum time interval must be greater than or equal to the processing delay of the paging early indication information, and the processing delay refers to the time interval required for the terminal to complete demodulation or detection after receiving the paging early indication information.
[0063] In one embodiment of the present application, the time domain location of the paging early indication information further comprises: (1) the time domain location of the paging early indication information is before N paging occasions and satisfies a minimum time interval; (2) the start time of the time domain position of the paging early indication information is the time domain end time of the synchronization signal block; (3) The end time of the time domain location of the paging early indication information must be the time domain start time of the synchronization signal block.
[0064] In one embodiment of the present application, the indication relationship between the paging early indication information and the paging occasion further includes any one of: (1) different paging early indication information indicates the same paging occasion; and (2) the same paging occasion is only indicated by the same paging early indication information, where the first contents indicated by the same paging early indication information are the same.
[0065] For example, according to (1), PEI1 points to PO1 and PO2, and PEI2 points to PO2 and PO3. Here, PEI1 and PEI2 point to the same PO, i.e. PO2 Further, for example, if both PEI1 and PEI2 indicate PO1 and PO2, PEI1 and PEI2 may be considered as paging early indication information that is repeatedly transmitted. However, at least one of the time domain location, frequency domain location, and associated SSB index where PEI1 and PEI2 are located is different.
[0066] Further, for example, according to (2), when the same PO is pointed to by one PEI, i.e., PO1, only through PEI1, PO1 cannot be pointed to by any PEI other than PEI1. Further, for example, one PO may be pointed to by PEI1 and PEI2, and the first contents pointed to by PEI1 and PEI2 are the same, and PEI1 and PEI2 may be regarded as one repetition.
[0067] In one embodiment of the present application, the paging early indication information is further carried by a downlink control information (DCI) or sequence.
[0068] In this embodiment, the paging early indication information may be physical layer control information, and may be a reference signal or a sequence, etc. The terminal can obtain the paging early indication information by detecting the downlink control information (DCI) of the physical downlink control channel sent by the network device, or by detecting the sequence sent by the network device.
[0069] In one embodiment of the present application, when the paging early indication information is carried by downlink control information (DCI), the indication manner of the first content includes at least one of a bitmap and a bit string.
[0070] Specifically, when the first content is indicated in the form of a bit string, the bit string includes a target bit, and the target bit includes at least a number of code points, and the code points indicate whether the UE associated with the paging group needs to monitor the corresponding PDCCH. Thus, the terminal determines whether the paging group associated with the paging occasion indicated by the paging early indication information needs to monitor the corresponding PDCCH according to the code points of the target bit. Wherein, different code points correspond to different paging groups or different terminals in the same paging group. Thus, the indication of the monitoring task by the target bit is realized, and the number of bits required for the paging early indication information is saved, which is favorable to reducing the performance loss.
[0071] For example, the paging early indication information indicates that the UEs associated with the PO are divided into four paging groups, and indicates whether the four paging groups need to monitor the paging PDCCH according to the target bit, as shown in Table 1 below.
[0072] [Table 1]
[0073] It should be noted that the groups or terminals represented by different code points may be reasonably set according to the paging configuration information of the network device.
[0074] For example, in manner 1, for two or more paging groups, code point 1 to code point N×W respectively indicate that terminals in one of the N×W paging groups need to monitor the corresponding PDCCH, and code point N×W+1 indicates that terminals in all N×W paging groups also need to monitor the corresponding PDCCH, or indicates that terminals in all N POs also need to monitor the corresponding PDCCH.
[0075] In manner 2, for three or more paging groups, codepoint 1 to codepoint N×W respectively indicate that terminals in one of the N×W paging groups need to monitor the corresponding PDCCH, codepoints N×W+1 to N×W+X respectively indicate that terminals in any two of the N×W paging groups need to monitor the corresponding PDCCH, where X is the number of different combinations of any two of the N×W paging groups, and codepoint N×W+X+1 indicates that terminals in all the N×W paging groups also need to monitor the corresponding PDCCH, or indicates that terminals in all the N POs also need to monitor the corresponding PDCCH.
[0076] In one embodiment of the present application, when the paging early indication information is carried by the downlink control information (DCI), the paging early indication information is used to indicate that the indication fields of the first contents are arranged in a preset arrangement order, where the preset arrangement order includes at least one of arranging according to a paging occasion associated with the paging early indication information, arranging according to a content type of the first contents, and arranging in ascending or descending order of the value of N.
[0077] In one embodiment of the present application, the downlink control information (DCI) of the PDCCH is divided into N+1 information blocks, where the N information blocks respectively correspond to monitoring actions in the N paging occasions, and the first or N+1 information block carries first configuration information, i.e., availability of a first signal, related to the N paging occasions.
[0078] In another embodiment, the configuration according to the content type of the first content is to first configure whether to monitor a paging PDCCH in N POs, then configure whether to monitor paging in N POs, and further configure whether to monitor system information updates, etc. in N POs.
[0079] Arranging in ascending or descending order of the value of N means first arranging the first content pointing to the first PO, then arranging the first content pointing to the second PO, and inferring based on this.
[0080] For example, the protocol specifies that the time domain location of the paging early indication information must satisfy the minimum time interval, and the time domain end location of the paging early indication information must satisfy the time domain start location of the SSB. The paging early indication information indicates N consecutive POs thereafter. It also satisfies that one PO can only be indicated by one paging early indication information. The upper layer configures candidate time intervals, numbers them, and carries the selected time interval number in the paging early indication information.
[0081] As shown in FIG. 5, the network device conveys paging configuration information in SIB1 in which the number of paging groups into which terminals on one PO are divided is four, which are designated as PO1, PO2, PO3, and PO4, respectively, and candidate values of N are 2, 4, and 8.
[0082] As shown in Figure 5, the paging early indication information represented by a one-way arrow indicates whether to monitor paging PDCCHs of N x W paging groups (where W represents the number of paging groups divided by the UE on one PO, and N POs have a total of N x W subgroups) and whether TRS / CSI-RS is available. After obtaining the paging early indication information, the terminal confirms that the minimum time interval between the paging early indication information and the subsequently associated N POs is a period of three SSBs, the period of the SSB is 20 ms, and indicates that the time interval is 60 ms and the value of N is 4.
[0083] Regarding the method of paging configuration information, method 1 includes adopting a bit string to map the paging configuration information. As shown in FIG. 5, the paging configuration information is packetized and arranged according to PO, and the DCI of PDCCH is divided into N+1=5 information blocks, where four information blocks respectively carry the non-common information of each of the four POs. The first information block carries the common information. Here, information block 1 indicates whether TRS / CSI-RS is available or not with 1 bit, where "0" indicates unavailable and "1" indicates available. Information block 2 corresponds to PO1, and is mapped in the manner of a bit string, and 3 bits indicate whether the four groups of PO1 need to monitor the paging PDCCH. Information blocks 3, 4, and 5 correspond to PO2, PO3, and PO4, respectively, and are mapped in the manner of a bit string, and 3 bits indicate whether the four groups of PO2, PO3, and PO4 need to monitor the paging PDCCH, which is specifically the same as the indication method of information block 2. Therefore, a total of 13 bits are required for indication.
[0084] Method 2: adopt bitmap to map paging configuration information. Paging configuration information is packetized and arranged according to PO, and DCI of PDCCH is divided into N+1=5 information blocks, where 4 information blocks respectively carry non-common information of 4 POs. The first information block carries common information. Here, information block 1 indicates whether TRS / CSI-RS is available or not with 1 bit, "0" indicates unavailable, "1" indicates available, 2 bits indicate the minimum time interval number, and 2 bits indicate the value number of N. Information blocks 2, 3, 4, and 5 correspond to PO1, PO2, PO3, and PO4, respectively, and are mapped in a bitmap manner, and each 4 bits indicates whether the 4 groups in PO1, PO2, PO3, and PO4 need to monitor paging PDCCH. "0" indicates monitoring, and "1" indicates non-monitoring. Therefore, a total of 5+4×4=21 bits are required to be indicated.
[0085] In one embodiment of the present application, FIG. 3 shows a third flowchart of a paging indication method of the embodiment of the present application, which includes the following steps:
[0086] Step 302: if a plurality of paging early indication information with first contents not consistent is received, it is determined that the paging early indication information is invalid.
[0087] Here, the multiple paging early indication information with inconsistent first contents indicate the same N paging occasions.
[0088] In this embodiment, the terminal does not want to receive multiple paging early indication information whose first content is inconsistent, and the multiple paging early indication information whose first content is inconsistent indicates the same N paging occasions. When the terminal receives multiple paging early indication information whose first content is inconsistent, it determines that the paging early indication information is invalid, and the terminal's monitoring action at this time may be monitoring or non-monitoring, or the specific terminal monitoring action at this time is determined by the network side or protocol agreement.
[0089] For example, when PEI1 and PEI2 jointly indicate PO1, the UE does not want the contents indicated by the received PEI1 and PEI2 to be inconsistent, so an error case is defined.
[0090] As a specific example, multiple PEIs (PEI1 and PEI2) indicate the same N POs, that is, the downlink control information (DCI) of multiple MOs in the same DRX cycle indicated by the PEIs must match.
