Description

Information receiving method, information sending method, device and communication system Technical Field

[0001] The embodiments of this application relate to the field of wireless communication technology. Background Technology

[0002] In the standardized 5G network developed under the 3rd Generation Partnership Project (3GPP), a large number of NR (New Radio) base stations have been deployed. NR base stations need to operate with a large bandwidth (e.g., 100MHz), require a large number of ports (64T / 64R), and have a shorter TTI (1ms). The energy consumption of NR base stations in baseband processing, digital front-end, and other functions is significantly higher than that of LTE base stations.

[0003] According to operator statistics, the average energy consumption of an NR base station is more than three times that of an LTE base station. Electricity costs account for nearly half of the cost of deploying 5G networks. More importantly, NR base stations still consume a significant amount of energy even during periods without service traffic. This is because NR base stations still need to transmit common signals, such as the Synchronization Singular Block (SSB), System Information Block (SIB, e.g., SIB1), System Information (SI), and paging, significantly reducing their energy efficiency. Energy saving in NR networks is a pressing issue that needs to be addressed. Furthermore, energy saving will also be a crucial problem to solve in future networks (such as 6G and beyond).

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application.

[0005] Summary of the Invention

[0006] The inventors discovered that the research procedures and signaling methods in 3GPP Release 19 support on-demand System Information Block Type 1 (SIB1) for terminal devices in idle or inactive modes. Therefore, cells supporting or using on-demand SIB1 have emerged, differing from traditional cells. However, it is currently unclear how the UE obtains the configuration of the on-demand SIB1-related wake-up signal (WUS) for a cell if it needs to acquire on-demand SIB1 again after the terminal device has camped on a cell supporting or using on-demand SIB1.

[0007] To address the aforementioned or other similar problems, embodiments of this application provide an information receiving method, an information sending method, an apparatus, and a communication system.

[0067] For ease of description, the following description uses a base station as an example of an access network device. In the following description, without causing confusion, "if...", "in the case of...", and "when..." can be used interchangeably.

[0068] The following examples illustrate the scenarios of embodiments of this application, but this application is not limited thereto.

[0069] Figure 1 is a schematic diagram of a communication system according to an embodiment of this application, illustrating the case of a terminal device and a network device as examples. As shown in Figure 1, the communication system 100 may include a network device 101, a terminal device 102, and a terminal device 103. For simplicity, Figure 1 only illustrates the case of two terminal devices and one network device, but the embodiments of this application are not limited to this.

[0070] In this embodiment, network device 101, terminal device 102, and terminal device 103 can transmit existing services or services that may be implemented in the future. For example, these services may include, but are not limited to: enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), ultra-reliable and low-latency communication (URLLC), Internet of Things (IoT) communication, and related communication of terminal devices with reduced capabilities, etc.

[0071] Terminal devices 102 and 103 can communicate with network device 101. For example, taking terminal device 102 as an example, terminal device 102 can send data to network device 101, such as using dynamic authorization or configured authorization transmission methods. Network device 101 can receive data sent by one or more terminal devices 102 and provide feedback or uplink scheduling information to terminal device 102, such as ACK / NACK confirmation information or uplink new transmission or retransmission scheduling information. Based on the feedback or uplink scheduling information, terminal device 102 can confirm the end of the transmission process, or can initiate new data transmission, or can retransmit data. Network device 101 can also send data to terminal device 102, and terminal device 102 can receive data sent by network device 101. In addition, different terminal devices can also communicate with each other; for example, terminal device 102 and terminal device 103 can exchange data.

[0072] It is worth noting that Figure 1 shows that both terminal device 102 and terminal device 103 are within the coverage area of ​​network device 101, but this application is not limited to this. Terminal device 102 and terminal device 103 may both be outside the coverage area of ​​network device 101, or one of terminal device 102 and terminal device 103 may be within the coverage area of ​​network device 101 while the other is outside the coverage area of ​​network device 101.

[0073] Figure 2 illustrates a deployment scenario of an NES cell according to an embodiment of this application. As shown in Figure 2, for example, an NES cell is co-deployed with a coverage-providing cell, which can also be referred to as an anchor cell, Cell A, an auxiliary cell, or a neighboring cell, to assist the on-demand SIB1 process of the NES cell. The NES cell can provide network capacity. As another example, an NES cell is co-deployed with its neighboring cells, and these cells can have completely overlapping, partially overlapping, or non-overlapping coverage areas. In Figure 2, communication can occur between the NES cell and the anchor cell, between the NES cell and its neighboring cells, and between the anchor cell and its neighboring cells, for example, through the X2 interface or the F1 interface.

[0074] It is worth noting that Figure 2 shows one terminal device in an NES cell, but this application is not limited to this; there can be more than one terminal device (UE) in an NES cell. Furthermore, Figure 2 shows the terminal device within the coverage area of ​​the NES cell, but this application is not limited to this; the terminal device can also be outside the coverage area of ​​the NES cell. In addition, in Figure 2, the anchor cell can also be deployed co-located with one or more NES cells, and one or more anchor cells can provide auxiliary information to an NES cell. An NES cell can have one or more neighboring NES cells, or it can have no neighboring NES cells; this application does not impose any restrictions on this.

[0075] In another deployment scenario of NES cells, the NES cell is deployed independently, and there can be more than one terminal device (UE) in the NES cell. The terminal device can be within or outside the coverage area of ​​the NES cell, but this application is not limited to this.

[0076] One of the working objectives of 3GPP Release 19, as shown in Table 1 below, is to study the process and signaling methods to support on-demand SIB1 for UEs in idle / inactive mode, including: triggering methods for uplink wake-up signals using existing signals / channels; providing the UE with the configuration of the wake-up signal; and exchanging wake-up signal configuration information between gNBs (if necessary).

[0077] Table 1

[0078] Currently, 3GPP RAN2 has agreed on relevant scenarios regarding on-demand SIB1. Figure 3 illustrates one scenario of on-demand SIB1 according to an embodiment of this application, specifically scenario 1a. As shown in Figure 3, in scenario 1a, the terminal device obtains the WUS configuration from the anchor cell, sends the WUS to the NES cell, and receives on-demand SIB1 from the NES cell. The agreed-upon details are shown in Tables 2 and 3 below:

[0079] Table 2

[0080] Table 3

[0081] In addition, 3GPP RAN1 agreed to continue studying on-demand SIB1 for terminal equipment in idle / inactive mode under the following three cases:

[0082] Case 1: The UE obtains the WUS configuration from the NES cell, sends the WUS to the NES cell, and receives on-demand SIB1 from the NES cell;

[0083] Case 2: The UE obtains the WUS configuration from the anchor cell, sends the WUS to the NES cell, and receives on-demand SIB1 from the NES cell, corresponding to scenario 1a where RAN2 agrees;

[0084] Case 3: The UE obtains WUS configuration information from the anchor cell, sends WUS to the anchor cell, and receives on-demand SIB1 from the anchor cell.

[0085] However, in the scenarios or situations mentioned above regarding on-demand SIB1, after the terminal device is camped on an NES cell, if the terminal device needs to obtain the on-demand SIB1 of that cell again, how does the UE obtain the configuration of the wake-up signal (WUS) related to the on-demand SIB1 of that cell? Therefore, the above issues need to be further discussed.

[0086] To address at least one of the above-mentioned problems, embodiments of this application provide an information receiving method, an information sending method, an apparatus, and a communication system.

[0087] First aspect of the embodiments

[0088] This application provides an information receiving method, which will be described from the perspective of a terminal device.

[0089] Figure 4 is a schematic diagram of an information receiving method according to an embodiment of this application. The method is applied to a terminal device. As shown in Figure 4, the method includes:

[0090] 401. The terminal device is camped in the first cell that supports or uses on-demand system information block type one (on-demand SIB1);

[0091] 402, The terminal device receives first information related to the wake-up signal (WUS) configuration information of the first cell on the first cell.

[0092] According to the above embodiments, the terminal device camps on a first cell that supports or uses on-demand system information block type 1 (on-demand SIB1) and receives first information related to the wake-up signal (WUS) configuration information of the first cell on the first cell. As a result, the terminal device can obtain the WUS configuration information of the first cell, which helps the terminal device and the first cell to have a consistent understanding of the WUS configuration information, thereby avoiding the failure of the UE to obtain on-demand SIB1 due to inconsistent understanding.

[0093] It is worth noting that Figure 4 above is only an illustrative description of the embodiments of this application, but this application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 4 above.

[0094] In some embodiments, the terminal device includes a terminal device in an RRC idle (RRC_IDLE) state or an RRC inactive (RRC_INACTIVE) state.

[0095] In some embodiments, the first cell is a cell that supports or uses on-demand SIB1, and may also be referred to as an NES cell or other similar names. Since the first cell is an NES cell, the System Information Block #1 (SIB1) of the first cell may also be referred to as the on-demand SIB1 of the first cell or other names.

[0096] In some embodiments, after the terminal device receives the on-demand SIB1 from the first cell and determines that the first cell is a suitable cell, the terminal device camps on the first cell. After the terminal device camps on the first cell, if the terminal device needs to obtain the on-demand SIB1 again, the terminal device can send WUS in the first cell, and the terminal device can receive first information related to the WUS configuration information of the first cell on the first cell.

[0097] In some embodiments, the WUS configuration information includes, for example, at least one of the following: information related to which cell the config applies, WUS transmission, SIB1 reception, and RAR Reception. Information related to the cell used for configuration includes, for example, the NES cell identifier (NES-CellId, which includes the physical cell identifier and / or frequency information); information related to WUS transmission includes, for example, the configuration related to SIB1 requests (SIB1-RequestConfig, which includes the configuration related to SSB, the configuration of the race occasion, the configuration of the random access preamble, the configuration of the root sequence of PRACH, and the configuration of the subcarrier spacing, etc.) and uplink frequency information (frequencyInfoUL, which includes the uplink frequency band list, the frequency of point A, and the TDD uplink and downlink configuration, etc.); information related to SIB1 reception includes, for example, the configuration of the PDCCH that schedules SIB1 (pdcch-ConfigSIB1, which includes the control resource set, search space, and subcarrier spacing configuration of the PDCCH); and information related to RAR reception includes, for example, the configuration of the PDCCH that schedules RAR (pdcch-ConfigOD-SIB1-RAR). Table 4 is an example definition of WUS configuration information.

[0098] Table 4: WUS Configuration Information

[0099] In some embodiments, the first information is sent by the network device to which the first cell belongs on the first cell. The first information includes the WUS configuration information of the first cell. In this case, the terminal device can directly obtain (or acquire) the WUS configuration information related to the first cell in the first cell, without having to obtain the WUS configuration information of the first cell from / back to the anchor cell (e.g., Cell A). This reduces cross-cell operations and lowers the complexity of the terminal device. Alternatively, the first information includes indication information indicating whether the WUS configuration information of the first cell has changed. If the WUS configuration information of the first cell changes, the terminal device returns to the anchor cell (e.g., Cell A) of the first cell to obtain the WUS configuration information of the first cell. Since the NES cell does not need to send WUS configuration information to the UE, the NES cell is more energy-efficient. These will be explained separately below.

[0100] (a) The situation where the terminal device obtains the WUS configuration information of the first cell from the first cell.

[0101] In some embodiments, the first information includes WUS configuration information of the first cell, or the first information is the WUS configuration information of the first cell. Therefore, the terminal device can directly obtain the WUS configuration information of the first cell from the first cell. In this case, the first information can be included in the paging message sent by the first cell to the terminal device, or in the WUS acknowledgment message, or in the System Information Block (SIB) of the first cell. Specific embodiments will be described below.

[0102] In some embodiments, the first information is included in a paging message sent from the first cell to the terminal device, or the first information is carried by the paging message, or the first information is indicated by the paging message.

[0103] In some embodiments, the paging message may be, for example, a Paging message for RRC, which may be a new Paging message or an existing Paging message used to find the terminal device in the RRC_IDLE state and RRC_INACTIVE state to receive the data of the terminal device being called.

[0104] In some embodiments, the paging message may also be a short message, namely downlink control information (DCI). The short message may be a new DCI or an existing short message used to notify terminal devices of RRC_IDLE, RRC_INACTIVE, and RRC_CONNECTED states regarding system information modifications and / or ETWS (Earthquake and Tsunami Warning System) / CMAS (Commercial Mobile Alert System) indications.

[0105] In some embodiments, both the Paging message and the Short Message are addressed via the P-RNTI (Paging-Radio Network Temporary Identifier) ​​on the PDCCH, but the Paging message is sent on the Paging Control Channel (PCCH) via the PDSCH, while the Short Message is sent directly via the PDCCH.

[0106] In some embodiments, the terminal device receives the paging message at its own paging occasion (PO).

[0107] For example, network devices associated with or corresponding to the first cell can send the paging message at all paging times (POs) in the first cell so that all terminal devices in the first cell can receive the paging message. However, each terminal device in the RRC Idle (RRC_Idle) or RRC Inactive (RRC_Inactive) state will calculate its own specific PO according to a specific formula, instead of receiving the paging message from all POs in the first cell. This saves power consumption of the terminal devices.

[0108] In some embodiments, when the paging message is a paging message, the terminal device in the RRC_IDLE state listens to the PDCCH channel addressing the P-RNTI to receive the first information and / or the paging initiated by the core network (referred to as CN paging), while the terminal device in the RRC_INACTIVE state listens to the PDCCH channel addressing the P-RNTI to receive the first information and / or the paging initiated by the RAN (referred to as RAN paging) and / or CN paging.

[0109] In some embodiments, when the paging message is a Short Message, the terminal device can receive the Short Message by listening to the PDCCH channel of the P-RNTI address. The terminal device does not need to continuously listen to the paging channel; it only needs to listen to the paging channel at one paging moment within a paging cycle.

[0110] In some embodiments, the first information is included in the confirmation message to WUS sent by the first cell to the terminal device, or the first information is carried by the confirmation message to WUS.

[0111] For example, a terminal device sends a WUS to a first cell to request on-demand SIB1 from the first cell. This WUS might be sent according to the current (or stored, or not updated) WUS configuration information of the first cell. Upon receiving the WUS, the first cell sends an acknowledgment message to the terminal device. This acknowledgment message can carry the aforementioned first information, allowing the terminal device to obtain the WUS configuration information of the first cell by receiving it. This acknowledgment message might be, for example, a RAR message.

[0112] In some embodiments, the first information is included in the System Information Block (SIB) of the first cell. In this case, the terminal device receives the SIB when the WUS configuration information of the first cell changes / is updated. The System Information Block of the first cell includes, for example, SIB1 / 2 / 3 / 4 / 5 / 6 / 7 / 8, etc. The embodiments in which the first information is included in different System Information Blocks will be described below.

[0113] As one implementation, the first information is included in the SIB1 (or on-demand SIB1) of the first cell. In this case, the terminal device obtains the on-demand SIB1 when the WUS configuration information of the first cell changes / is updated. Obtaining the on-demand SIB1 of the first cell includes: listening to the PDCCH that schedules the on-demand SIB1 of the first cell, and / or receiving the on-demand SIB1 of the first cell carried on the PDSCH scheduled by the PDCCH.

[0114] In some embodiments, the search space and / or coreset of the PDCCH for scheduling the on-demand SIB1 of the first cell are configured or predefined by the network device. For example, when configured by the network device, the configuration information of the search space and / or coreset of the PDCCH for scheduling the on-demand SIB1 of the first cell can be included in the MIB changed by the first cell, or included in the WUS configuration information. This embodiment of the application does not limit this.

[0115] In some embodiments, the first cell may voluntarily (or proactively) send on-demand SIB1 containing updated / changed WUS configuration information of the first cell. For example, when the first cell changes / updates its WUS configuration information, it voluntarily (or proactively) sends on-demand SIB1 containing updated / changed WUS configuration information of the first cell. In this case, when the terminal device knows that the WUS configuration information of the first cell has changed / updated, it does not trigger or send WUS related to the on-demand SIB1 of the first cell, but directly executes step 402 to obtain the on-demand SIB1 of the first cell containing updated / changed WUS configuration information.

[0116] Alternatively, the first cell may also send on-demand SIB1 containing updated / changed WUS configuration information of the first cell upon request from the terminal device. For example, when the first cell's WUS configuration information changes / updates, it first receives the WUS from the terminal device and then sends on-demand SIB1 containing the updated / changed WUS configuration information of the first cell. In this case, when the terminal device knows that the first cell's WUS configuration information has changed / updated, it triggers or sends a WUS related to the on-demand SIB1 of the first cell based on the first cell's current (or stored or not updated) WUS configuration information to request the first cell to send on-demand SIB1 containing the updated / changed WUS configuration information, and then executes step 402 to obtain the on-demand SIB1 of the first cell.

[0117] In some embodiments, in order for the terminal device to correctly receive updated / changed WUS configuration information, the first cell may notify the terminal device that its WUS configuration information has been updated / changed. Therefore, the information receiving method of this application further includes:

[0118] The terminal device receives second information from the first cell, the second information including system information change indication information of the first cell.

[0119] Therefore, when the WUS configuration information of the first cell changes / updates, the first cell sends the second information so that the terminal device knows that the WUS configuration information of the first cell has changed / updated, and when or after knowing that the WUS configuration information of the first cell has changed / updated, it receives on-demand SIB1 including the updated WUS configuration information from or in the first cell.

[0120] In some embodiments, the second information may be included in a short message of the first cell, or the second information may be carried by a short message of the first cell. For details regarding this short message, please refer to Table 4 below; it will not be repeated here.

[0121] In some embodiments, the terminal device receives the second information in the current modification period (Modification period n), and obtains on-demand SIB1 including the first information (or the WUS configuration information updated by the first cell) starting from the next modification period (Modification period n+1) or in the first time period on the first cell.

[0122] For example, after receiving the second information in the current modification cycle, the terminal device does not trigger or send WUS, but directly receives the first information (or the updated WUS configuration information of the first cell) on the first cell from the start of the next modification cycle or in the first time period, that is, obtains the on-demand SIB1 of the first cell.

[0123] In some embodiments, the terminal device receives the second information on the first cell during the current modification period (Modification period n), and obtains on-demand SIB1 including the first information (or the WUS configuration information updated by the first cell) on the first cell during the current modification period (Modification period n) or the second time period.

[0124] For example, after receiving the second information in the current modification period, the terminal device triggers or sends WUS to the first cell using the current (or stored or not updated) WUS configuration information of the first cell in the current modification period or the second time period. Then, it receives the confirmation information for WUS on the first cell using the current (or stored or not updated) WUS configuration information of the first cell in the current modification period or the second time period, and obtains the on-demand SIB1 of the first cell, including the first information, using the current (or stored or not updated) WUS configuration information of the first cell in the current modification period or the second time period.

[0125] In some embodiments, the start time and / or length and / or end time of the first time period and the second time period are configured by the network device, for example, by the first cell (NES cell) or the anchor cell (Cell A). The configuration of the first time period and the second time period is included, for example, in the system information configuration of the first cell, or in the system information or RRC message (e.g., RRC release message) of the anchor cell, or in the WUS configuration information. Alternatively, the start time and / or length and / or end time of the first time period and the second time period are predefined. This application does not impose any limitations on this.

[0126] It should be noted that before acquiring the on-demand SIB1 of the first cell, the terminal device has already obtained the start time and / or length and / or end time of the first or second time period.

[0127] In some embodiments, the first time period may overlap with the current modification period, or may not overlap with the current modification period, or may overlap with the next modification period, or may not overlap with the next modification period, or may overlap with both the current modification period and the next modification period. This application does not impose any restrictions on this.

[0128] In some embodiments, the second time period may overlap with the current modification cycle, or may not overlap with the current modification cycle, or may overlap with the next modification cycle, or may not overlap with the next modification cycle, or may overlap with both the current modification cycle and the next modification cycle. This application does not impose any restrictions on this.

[0129] As some implementations, the first information is included in a second system information block of the first cell that is different from the on-demand SIB1. The second system information block is a system information block other than SIB1 of the first cell. For example, the second system information block can be any one of the system information blocks SIB2 / 3 / 4 / 5 / 6 / 7 / 8 of the first cell. In this application, the second system information block can also be referred to as SIBn.

[0130] In some embodiments, when the first information is included in a second system information block of the first cell that is different from the on-demand SIB1, when the WUS configuration information of the first cell is changed / updated, the terminal device first obtains the on-demand SIB1 of the first cell, and then obtains the second system information block of the first cell including the first information according to the scheduling information in the on-demand SIB1.

[0131] In some embodiments, the method further includes:

[0132] The terminal device receives third information on the first cell, the third information including system information change indication information of the first cell.

[0133] Therefore, the terminal device can know that the WUS configuration information of the first cell has changed / updated. The "third information" is similar to the "second information" in the previous embodiment, and can be found in the relevant content of the previous embodiment, which will not be repeated here.

[0134] In some embodiments, when or after the WUS configuration information of the first cell is changed / updated, for example, when or after the terminal device receives the aforementioned third information on the first cell during the current modification period n, the method further includes:

[0135] The terminal device obtains the on-demand SIB1 of the first cell;

[0136] Based on the scheduling information in the on-demand SIB1, a second system information block including the first information is obtained on the first cell.

[0137] In some embodiments, the method by which the terminal device obtains the on-demand SIB1 of the first cell, or the method by which the network device sends the on-demand SIB1 of the first cell on the first cell, can be found in the relevant content of the foregoing embodiments.

[0138] For example, when the system information of the first cell changes / updates, the first cell can autonomously (or proactively) send (broadcast) on-demand SIB1. In this case, when the terminal device knows that the WUS configuration information of the first cell has changed / updated, or when the terminal device receives the aforementioned third information on the first cell during the current modification period, or when it does not trigger or send WUS related to the on-demand SIB1 of the first cell, it directly obtains the on-demand SIB1 of the first cell, and then obtains the second system information block including the first information on the first cell according to the scheduling information in the on-demand SIB1.

[0139] Alternatively, if the system information of the first cell changes / updates, the first cell may also send on-demand SIB1 upon request from the terminal device. For example, when the system information of the first cell changes / updates, it first receives the WUS from the terminal device and then sends on-demand SIB1. In this case, when the terminal device knows that the WUS configuration information of the first cell has changed / updated, or after the terminal device receives the aforementioned third information on the first cell during the current modification period, it triggers or sends a WUS related to the on-demand SIB1 of the first cell according to the current (or stored or not updated) WUS configuration information of the first cell, to request the first cell to send on-demand SIB1. Then, according to the scheduling information in the on-demand SIB1, it obtains the second system information block including the first information on the first cell.

[0140] In some embodiments, the terminal device receives the third information in the current modification period (Modification period n), and in the next modification period or the third time period, obtains the on-demand SIB1 of the first cell in the first cell, and then, according to the scheduling information in the on-demand SIB1, obtains the second system information block including the first information in the first cell starting from the modification period after the current modification period (Modification period n+m, where m is a positive integer).

[0141] For example, after receiving the third information in the current modification period, the terminal device does not trigger or send WUS, but directly receives on-demand SIB1 in the first cell in the next modification period or the third time period. Then, according to the scheduling information in on-demand SIB1, it obtains the second system information block including the first information in the first cell starting from the modification period after the current modification period.

[0142] In some embodiments, the terminal device receives the third information on the first cell during the current modification period (Modification period n), and obtains on-demand SIB1 on the first cell during the current modification period (Modification period n) or a fourth time period. Then, according to the scheduling information in the on-demand SIB1, it obtains a second system information block including the first information on the first cell starting from the modification period (Modification period n+m, where m is a positive integer) after the current modification period.

[0143] For example, after receiving the third information in the current modification period, the terminal device triggers or sends WUS to the first cell using the current (or stored or not updated) WUS configuration information of the first cell. Then, in the current modification period or the fourth time period, it receives confirmation information for WUS on the first cell using the current (or stored or not updated) WUS configuration information of the first cell, obtains the on-demand SIB1 of the first cell using the current (or stored or not updated) WUS configuration information of the first cell, and obtains the second system information block including the first information on the first cell starting from the modification period after the current modification period.

[0144] In some embodiments, the modification period following the current modification period (Modification period n+m, where m is a positive integer) can be any modification period following the current modification period, such as the next modification period (Modification period n+1) or the next modification period after that (Modification period n+2).

[0145] In some embodiments, the start time and / or length and / or end time of the third and fourth time periods are configured by the network device, for example, by the first cell (NES cell) or the anchor cell (Cell A). The configuration of the third and fourth time periods is included, for example, in the system information configuration of the first cell, or in the system information or RRC message (e.g., RRC release message) of the anchor cell, or in the WUS configuration information of the first cell. Alternatively, the start time and / or length and / or end time of the third and fourth time periods are or are predefined. This application does not impose any limitations on this.

[0146] It should be noted that before acquiring the on-demand SIB1 of the first cell, the terminal device has already obtained the start time and / or length and / or end time of the third or fourth time period.

[0147] In some embodiments, the third time period may overlap with the current modification period, or may not overlap with the current modification period, or may overlap with the next modification period, or may not overlap with the next modification period, or may overlap with both the current modification period and the next modification period. This application does not impose any restrictions on this.

[0148] In some embodiments, the fourth time period may overlap with the current modification period, or may not overlap with the current modification period, or may overlap with the next modification period, or may not overlap with the next modification period, or may overlap with both the current modification period and the next modification period. This application does not impose any restrictions on this.

[0149] (ii) The terminal device obtains the WUS configuration information of the first cell from the anchor cell (e.g., Cell A) of the first cell.

[0150] In some embodiments, the first information includes indication information indicating whether the WUS configuration information of the first cell has changed. In this case, the terminal device needs to return to the anchor cell (e.g., Cell A) of the first cell to obtain the WUS configuration information of the first cell.

[0151] In some embodiments, the first information may be included in the downlink control information (DCI) of a short message used for paging, such as DCI format 1_0; or, the first information may be included in the DCI corresponding to a paging early indication (PEI); or, the first information may be included in a paging message.

[0152] In some embodiments, the indication information includes one bit. Different values ​​of this one bit indicate whether the WUS configuration information of the first cell has changed. For example, a bit value of 1 indicates a change in the WUS configuration information of the first cell, a bit value of 0 indicates no change, and vice versa. Alternatively, the presence or absence of this one bit indicates whether the WUS configuration information of the first cell has changed. For example, the presence of this one bit indicates a change, the absence of this one bit indicates no change, and vice versa.

[0153] In some embodiments, taking the first information carried by the DCI of a short message as an example, the 1 bit can be any one of Bits 5 to 8 in the short message. Table 5 is a definition of a short message. As shown in Table 5, a short message includes Bits 1 to 8, where Bit 1 is the most significant bit. Any one of Bits 5 to 8 in Table 5 can be used as the first information to indicate whether the WUS configuration information of the first cell has changed. For example, when Bit 5 is 1, it indicates that the on-demand SIB1 has changed.

[0154] Table 5: short message

[0155] In some embodiments, when the indication information indicates a change in the WUS configuration information of the first cell, the method further includes:

[0156] The terminal device obtains the updated WUS configuration information of the first cell on the anchor cell of the first cell.

[0157] For example, the terminal device obtains the updated WUS configuration information of the first cell by acquiring the system information and / or RRC messages (such as RRC release messages) of the anchor cell.

[0158] In some embodiments, when the indication information indicates that the WUS configuration information of the first cell has not changed, the method further includes:

[0159] The terminal device uses the current (or stored, not updated, or previously acquired) WUS configuration information of the first cell for subsequent WUS triggering or sending and / or receiving WUS confirmation messages and / or obtaining on-demand SIB1.

[0160] The following describes how the terminal device uses the WUS configuration information when or after obtaining the WUS configuration information of the first cell (e.g., through the methods described in (I) or (II) above).

[0161] In some embodiments, when the terminal device receives the WUS configuration information of the first cell, it may immediately use the WUS configuration information, or start using the WUS configuration information from the next modification cycle, or start using the WUS configuration information from the next paging cycle or paging DRX cycle, or use the WUS configuration information at the first moment, for subsequent WUS triggering or sending and / or receiving WUS confirmation messages and / or obtaining on-demand SIB1.

[0162] In some embodiments, after sending a paging message containing or indicating the first information, the network device may use the WUS configuration information immediately, or start using the WUS configuration information from the next modification cycle, or start using the WUS configuration information from the next paging cycle or paging DRX cycle, or use the WUS configuration information at the first moment for subsequent WUS reception and / or the transmission of WUS acknowledgment messages and / or the transmission of on-demand SIB1.

[0163] In some embodiments, the first moment is configured by the network device or predefined. The first moment can be a relative moment or an absolute moment, and this application does not limit it in this regard.

[0164] In some embodiments, the terminal device uses the acquired WUS configuration information until at least one of the following events occurs:

[0165] When the terminal device leaves the first cell, for example, when the terminal device leaves the coverage of the first cell, it can delete or release the WUS configuration information of the first cell, or delete or release the WUS configuration information of the first cell after a period of time.

[0166] The terminal device cell is reselected to a second cell that is different from the first cell. This second cell may be, for example, the anchor cell of the first cell (e.g., Cell A) or other NES cells. For example, when the terminal device is reselected from the first cell to the second cell, the WUS configuration information of the first cell may be deleted or released, or the WUS configuration information of the first cell may be deleted or released after a period of time.

[0167] The terminal device obtains updated WUS configuration information. For example, after the terminal device selects a second cell, it obtains the updated WUS configuration information of the first cell from the system information of the second cell, or obtains the updated WUS configuration information of the first cell from a paging message containing WUS configuration information sent by the second cell. The terminal device can then delete or release the previous WUS configuration information of the first cell.

[0168] In some embodiments, after a terminal device camps on a first cell with on-demand SIB1, if the terminal device's RRC layer needs to obtain the on-demand SIB1 of the first cell, the RRC layer and MAC layer inside the terminal device need to interact, and the on-demand SI procedure based on random access messages (e.g., Msg1, Msg3, etc.) is repeatedly used in the on-demand SIB1 acquisition process. However, the functions of the RRC layer and MAC layer inside the terminal device and how the RRC layer and MAC layer interact are currently unclear.

[0169] Therefore, this application provides a method for interaction between the RRC layer and the MAC layer within a terminal device when the terminal device obtains the on-demand SIB1 of the first cell using the on-demand SI procedure based on random access messages, which will be described below.

[0170] In some embodiments, when it is necessary to obtain the on-demand SIB1 of the first cell, the method further includes:

[0171] The RRC layer of the terminal device requests the MAC layer to obtain the on-demand SIB1 of the first cell, and / or the MAC determines information related to sending WUS according to the request of the RRC layer and sends a random access message to the first cell.

[0172] In some embodiments, the information determined by the MAC layer related to sending WUS includes:

[0173] The preamble corresponding to WUS; and / or

[0174] Physical random access channel resources (PRACH resource); and / or

[0175] Random access parameters (RA parameters); and / or

[0176] Carrier, such as supplementary uplink carrier (SUL) or normal uplink carrier (NUL).

[0177] In some embodiments, the random access parameters include at least one of the following: the identifier of the NES cell, pramble transmission power, the step size for increasing pramble transmission power, the maximum number of pramble transmissions, the SSB threshold, the window size for receiving the RAR, the time information for receiving the RAR, the control resource set (Coreset) information and / or the search space (SS) information for receiving the RAR, etc.

[0178] In some embodiments, the RRC layer instructs the MAC layer to include at least one of the following: to obtain the identifier of the first cell on-demand SIB1 (e.g., PCI, cell ID, or CGI, etc.), the frequency information of the first cell (e.g., ARFCN), or the WUS configuration information of at least one first cell.

[0179] In some embodiments, when it is necessary to obtain the on-demand SIB1 of the first cell, if the on-demand SIB1 is not broadcast in the first cell, or if the terminal device does not detect the on-demand SIB1 in the current first cell, the RRC layer of the terminal device requests the MAC layer to obtain the on-demand SIB1 of the first cell.

[0180] In some embodiments, after the MAC sends a random access message to the first cell, the method further includes:

[0181] The MAC layer of the terminal device receives the confirmation information from the first cell regarding the WUS and notifies the RRC layer of the confirmation information.

[0182] In some embodiments, when it is necessary to obtain the on-demand SIB1 of the first cell, the method further includes:

[0183] The RRC layer of the terminal device determines the information related to sending the random access message and requests or triggers the MAC layer to use the information related to sending the random access message to initiate a random access procedure.

[0184] In some embodiments, the information determined by the RRC layer related to sending random access messages includes at least one of the following:

[0185] The preamble corresponding to the random access message;

[0186] Physical random access channel resource (PRACH resource);

[0187] Random access parameters (RA parameters); or

[0188] Carrier, such as supplementary uplink carrier (SUL) or normal uplink carrier (NUL).

[0189] In some embodiments, the random access parameters include at least one of the following: the identifier of the NES cell, pramble transmission power, the step size for increasing pramble transmission power, the maximum number of pramble transmissions, the SSB threshold, the window size for receiving the RAR, the time information for receiving the RAR, the control resource set (Coreset) information and / or the search space (SS) information for receiving the RAR, etc.

[0190] In some embodiments, the information determined by the RRC layer related to sending random access messages is WUS configuration information related to the first cell, or a portion of the WUS configuration information related to the first cell (e.g., excluding information related to receiving on-demand SIB1).

[0191] In some embodiments, the RRC layer determines information related to sending random access messages based on the identifier (e.g., PCI, cell ID, or CGI, etc.) of the first cell to be obtained on-demand SIB1 and / or the frequency information (e.g., ARFCN) of the first cell, as well as the WUS configuration information of the first cell.

[0192] In some embodiments, when it is necessary to obtain the on-demand SIB1 of the first cell, if the on-demand SIB1 is not broadcast in the first cell, or if the terminal device does not detect the on-demand SIB1 in the current first cell, the RRC layer of the terminal device determines information related to sending the random access message.

[0193] In some embodiments, after the MAC layer initiates a random access procedure, the method further includes:

[0194] The MAC layer of the terminal device receives the confirmation information from the first cell regarding the WUS and notifies the RRC layer of the confirmation information.

[0195] Figure 5 is a schematic diagram of obtaining on-demand SIB1 according to an embodiment of this application. In Figure 5, the terminal device obtains the on-demand SIB1 of the first cell using the on-demand SI process based on random access messages.

[0214] Condition 9: NUL is selected;

[0215] If yes, proceed to step 508; otherwise, proceed to step 509.

[0216] 508, The RRC layer of the terminal device triggers the MAC layer to initiate random access on the NUL;

[0217] 509. The terminal device initiates the Msg3-based on-demand SIB1 process to obtain the on-demand SIB1 of the first cell.

[0218] In some embodiments, steps 501 to 509 in FIG5 above are all optional steps. That is, the terminal device of this application can obtain the on-demand SIB1 of the first cell using the method shown in FIG5, or it can obtain the on-demand SIB1 of the first cell using other methods. This application does not limit this.

[0219] In some embodiments, if no on-demand SIB1 is broadcast in the first cell, or if the terminal device does not detect on-demand SIB1 in the current first cell, steps 502, 504, 506, and 508 in FIG5 are executed. For example, if step 501 determines no and no on-demand SIB1 is broadcast in the first cell, step 502 is executed; if step 503 determines no and no on-demand SIB1 is broadcast in the first cell, step 504 is executed; if step 505 determines no and no on-demand SIB1 is broadcast in the first cell, step 506 is executed; and if step 507 determines no and no on-demand SIB1 is broadcast in the first cell, step 508 is executed.

[0220] Based on the method shown in Figure 5, the supplementary content to the standard is shown in Table 6 below:

[0221] Table 6: Supplements to the Standard (Example 1)

[0222] The implementation methods for the functions and interactions of the RRC layer and MAC layer inside the terminal device can be implemented independently or in combination with the aforementioned implementation method for the terminal device to obtain first information related to the WUS configuration information of the first cell on the first cell.
