Description

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

[0001] The embodiments of the present application relate to the field of wireless communication technologies. Background Art

[0002] A large number of NR (New Radio) base stations have been deployed in the 5th Generation Mobile Communication Technology (5G) networks standardized by the 3rd Generation Partnership Project (3GPP). NR base stations require large bandwidths (e.g., 100MHz), a large number of ports (64T / 64R), and shorter time intervals (TTIs) (1ms). Consequently, NR base stations consume significantly more energy than LTE base stations for functions such as baseband processing and digital front-ends.

[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. Nearly half of the cost of deploying 5G networks by operators is electricity expenses. More importantly, even in periods of no business, the energy consumption of NR base stations is still very high, because even when there is no business, NR base stations still need to send public signals, such as Synchronization Signal Block (SSB), System Information Block (SIB, such as SIB1), System Information (SI) and paging, which greatly reduces the energy efficiency of NR base stations. Energy saving in NR networks is an urgent problem to be solved. In addition, in future networks (such as 6G or later networks), the problem of network energy saving also needs to be solved.

[0004] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0005] Summary of the Invention

[0006] The inventors discovered that 3GPP Release 19 research procedures and signaling methods support on-demand SIB1 for terminal devices in idle or inactive mode. As a result, cells that support or use on-demand SIB 1, unlike traditional cells, have emerged. However, it is currently unclear how to provide Wake Up Signal (WUS) configuration information for cells that support or use on-demand SIB 1 to terminal devices in idle or inactive mode.

[0007] Furthermore, it is unclear whether WUS configuration information needs to be exchanged between gNBs.

[0008] In addition, for a terminal device that receives WUS configuration information, it is unclear how it sends a wake-up signal and whether different processing is required.

[0009] In order to solve at least one of the above problems or other similar problems, the embodiments of the present application provide an information receiving and sending method, device and communication system.

[0073] For ease of description, the following description will be made using a base station as an example of an access network device. In the following description, "if ...", "under ..." and "when ..." can be used interchangeably without causing confusion.

[0074] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0075] FIG1 is a schematic diagram of a communication system according to an embodiment of the present application, schematically illustrating a situation taking a terminal device and a network device as an example. As shown in FIG1 , a communication system 100 may include a network device 101, a terminal device 102, and a terminal device 103. For simplicity, FIG1 illustrates only two terminal devices and one network device as an example, but the embodiments of the present application are not limited thereto.

[0076] In the embodiment of the present application, existing services or future services can be transmitted between the network device 101, the terminal device 102, and the terminal device 103. 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), and related communications of terminal devices with reduced capabilities, etc.

[0077] Among them, 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, for example, using dynamic authorization or configured authorization transmission mode. Network device 101 can receive data sent by one or more terminal devices 102, and feedback information or uplink scheduling information to terminal device 102, such as confirmation ACK / non-confirmation NACK information or uplink new transmission or retransmission scheduling information, etc. Terminal device 102 can confirm the end of the transmission process, or can also perform new data transmission, or can retransmit data based on the feedback information or uplink scheduling information. Network device 101 can also send data to terminal device 102, and terminal device 102 receives data sent by network device 101. In addition, different terminal devices can also communicate with each other. For example, data can be exchanged between terminal device 102 and terminal device 103.

[0078] It is worth noting that FIG1 shows that terminal device 102 and terminal device 103 are both within the coverage range of network device 101, but the present application is not limited thereto. Terminal device 102 and terminal device 103 may both be outside the coverage range of network device 101, or one of terminal device 102 and terminal device 103 may be within the coverage range of network device 101 and the other may be outside the coverage range of network device 101.

[0079] FIG2 illustrates a deployment scenario of an NES cell according to an embodiment of the present application. As shown in FIG2 , for example, an NES cell is co-deployed with a cell providing coverage, where the cell providing coverage may also be referred to as an anchor cell, and the NES cell may provide network capacity. For another example, an NES cell and a neighboring cell of the NES cell are co-deployed, and the NES cell and the neighboring cell of the NES cell may have completely overlapping coverage areas, partially overlapping coverage areas, or non-overlapping coverage areas. In FIG2 , communication can be performed between the NES cell and the anchor cell, between the NES cell and the neighboring cell of the NES, and between the anchor cell and the neighboring cell of the NES cell, for example, via an X2 interface or an F1 interface.

[0080] It is worth noting that FIG2 shows a terminal device in the NES cell, but the present application is not limited to this. The NES cell may also have more than one terminal device (UE). In addition, FIG2 shows that the terminal device is within the coverage of the NES cell, but the present application is not limited to this. The terminal device may also be outside the coverage of the NES cell. In addition, in FIG2, the anchor cell may also be co-deployed with one or more NES cells. An NES cell may have one or more neighboring cells of the NES cell, or may have no neighboring cells of the NES cell.

[0081] Figure 3 illustrates another deployment scenario for an NES cell according to an embodiment of the present application. As shown in Figure 3 , the NES cell is deployed standalone. It is worth noting that while Figure 2 illustrates a single terminal device in the NES cell, the present application is not limited to this. An NES cell may also contain more than one terminal device (UE). Furthermore, Figure 3 illustrates a terminal device within the coverage area of ​​the NES cell, but the present application is not limited to this. Each terminal device may also be outside the coverage area of ​​the NES cell.

[0082] One of the objectives of 3GPP Release 19 is as shown in Table 1 below: to study procedures 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 wake-up signal configuration to UEs; and exchanging at least wake-up signal configuration information between gNBs (if necessary).

[0083] Table 1

[0084] However, it is currently unclear how WUS configuration information is provided to terminal devices in idle or inactive mode, whether WUS configuration information needs to be exchanged between gNBs, or whether idle / inactive mode terminal devices in Release 19 and later (including 6G and later generations) are handled differently. Therefore, further discussion of these issues is needed.

[0085] In response to at least one of the above problems, embodiments of the present application provide a method, device, and communication system for receiving and sending information.

[0086] Embodiments of the first aspect

[0087] An embodiment of the present application provides a method for receiving and sending information, which is described from the perspective of a terminal device.

[0088] FIG4 is a schematic diagram of a method for receiving and sending information according to an embodiment of the present application. The method is applied to a terminal device. As shown in FIG4 , the method includes:

[0089] 401. The terminal device receives Wake Up Signal (WUS) configuration information related to the first cell sent by the network device.

[0090] 402. The terminal device sends a wake-up signal according to the wake-up signal configuration information.

[0091] According to the above embodiment, the terminal device receives the WUS configuration information related to the first cell sent by the network device. As a result, the terminal device can send a WUS signal according to the WUS configuration information to request the first cell to send SIB1 (also known as on-demand SIB1), thereby helping the terminal device determine whether to use the first cell as a serving cell, or use the public configuration of the first cell provided in the SIB1 to perform a subsequent random access process or receive paging, etc. The method is simple and easy to implement.

[0092] In addition, the first cell can send SIB1 upon receiving a request from the terminal device, which is beneficial for saving energy of the network device.

[0093] It is worth noting that FIG4 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG4 above.

[0094] In some embodiments, in 401, 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, in 401, the first cell is a cell that supports or uses on-demand SIB1, which may also be referred to as an NES cell in the following embodiments.

[0096] In some embodiments, in 401, the wake-up signal (WUS) configuration information includes information related to WUS, for example, at least one of the following information: time resources and / or frequency resources of WUS; index of WUS sequence; maximum number of WUS transmissions; WUS transmission power ramping step; expected WUS receiving power.

[0097] In some embodiments, at least one of the following WUS-related information is predefined: WUS time resource and / or frequency resource; WUS sequence index; maximum WUS transmission times; WUS transmit power ramping step; and expected WUS receive power. Thus, by predefining at least one WUS-related information, the remaining WUS-related information can be configured via WUS configuration information, thereby saving bits in signaling for transmitting the WUS configuration information.

[0098] In some embodiments, the information related to the WUS includes time resources and / or frequency resources of the WUS, and there is a predefined correspondence between the time resources and / or frequency resources of the WUS and the position of the SSB of the first cell.

[0099] In some embodiments, the correspondence between the time resources and / or frequency resources of the WUS and the position of the SSB of the first cell includes: the time difference between the WUS time domain resources and the SSB time domain resources is a predefined offset value, for example, the predefined offset value is, for example, N symbols (symbol) or N slots (slot); and / or

[0100] The difference between the minimum or maximum resource block (RB) index of the WUS and the minimum or maximum RB index of the SSB is a predefined integer, for example, the difference between the minimum or maximum RB index of the WUS and the minimum or maximum RB index of the SSB is X (X is a predefined integer) RBs; or, the difference between the minimum or maximum subcarrier (Subcarrier) index of the WUS and the minimum or maximum subcarrier index of the SSB is a predefined integer; or, the difference between the minimum or maximum subband (Subband) index of the WUS and the minimum or maximum subband index of the SSB is a predefined integer, etc.

[0101] In some embodiments, the WUS configuration information includes PRACH-related information, for example, at least one of the following information: RACH general configuration (RACH-ConfigGeneric), SSB index (SSB-Index), random access preamble index (ra-PreambleIndex), random access moment (ra-Occasion) information, PRACH root sequence index, PRACH subcarrier spacing, etc.

[0102] In some embodiments, the WUS configuration information is sent by the network device through a first cell or in the first cell, or the WUS configuration information is sent by the network device through a second cell or in the second cell, wherein the second cell is a cell different from the first cell, for example, the second cell is an anchor cell providing coverage or a neighboring cell of the first cell.

[0103] In some embodiments, the above-mentioned second cell may also be a cell associated with or corresponding to the first cell, and the association or correspondence between the first cell and the second cell may be configured by network equipment or operation administration and maintenance (OAM); or, the above-mentioned second cell may also be a cell having a neighboring cell relationship with the first cell, for example, the second cell is in the neighbor cell relationship table (Neighbour Cell Relation Table) of the first cell, or the second cell is in the neighbor cell relationship table of the first cell and has a specific mark, for example, the mark can be used to identify that the second cell provides NES-related configuration or information for the first cell.

[0104] The following describes a case where the WUS configuration information is sent by the network device through the first cell.

[0105] In some embodiments, the WUS configuration information is carried by a synchronization information block (SSB) of the first cell.

[0106] In some embodiments, the values ​​of ssb-SubcarrierOffset and / or pdcch-ConfigSIB1 of the Master Information Block (MIB) in the SSB are used, for example, to give a new meaning to the value of reserved in the prior art, to indicate WUS configuration information. The ssb-SubcarrierOffset of the MIB includes 4 bits, and the pdcch-ConfigSIB1 of the MIB includes 8 bits. Therefore, at least 12 bits of the MIB in the SSB can be used to provide WUS configuration information.

[0107] Table 2 shows the MIB of the first cell. The MIB includes parameters ssb-SubcarrierOffset and pdcch-ConfigSIB1. The parameter pdcch-ConfigSIB1 includes controlResourceSetZero and searchSpaceZero.

[0108] Table 2

[0109] For example, ssb-SubcarrierOffset of the SSB (MIB) and some reserved values ​​of pdcch-ConfigSIB1 shown in Table 3 and Table 4 may be used to provide WUS configuration information.

In Table 4, k SSB The corresponding value is 14, 16 × ControlResourceSetZero + SearchSpaceZero value is 0, 1, ..., 255 The value of (reserved value in the prior art) can be used to provide WUS configuration information, that is, k SSB When the value is 14, 8 bits of PDCCH-ConfigSIB1 can be used to indicate WUS configuration information.

[0113] Table 4

[0114] In some embodiments, the WUS configuration information is carried by a first system information block, and a control resource set (coreset) and a search space (SS) of a physical downlink control channel (PDCCH) of the first system information block are indicated by a synchronization information block (SSB) of the first cell. For example, the coreset and SS of the PDCCH of the first system information block are indicated by PDCCH-ConfigSIB1 in the SSB (MIB).

[0115] In some embodiments, a transmission period of the first system information block is configured or predefined by the network.

[0116] In some embodiments, the transmission period of the first system information block is greater than the transmission period of the SIB1 of the first cell, or the number of bits of the first system information block is less than the number of bits of the SIB1 of the first cell. In this way, the resources occupied by the first system information block can be reduced, thereby achieving the purpose of energy saving of the network device.

[0117] When the first cell is an NES cell, the PDCCH-ConfigSIB1 in the SSB (MIB) of the first cell indicates the coreset and SS of the PDCCH of the first system information block, but when the first cell is not an NES cell, the PDCCH-ConfigSIB1 in the SSB (MIB) of the first cell indicates the coreset and SS of the PDCCH of SIB1. If the terminal device does not know whether the first cell is an NES cell, the terminal device also does not know whether the PDCCH-ConfigSIB1 in the SSB (MIB) of the first cell indicates the coreset and SS of the PDCCH of the first system information block or the coreset and SS of the PDCCH of SIB1. Therefore, after the terminal device receives the PDCCH indicated by the SSB (MIB) of the first cell, it may use an incorrect format to parse the PDCCH. For example, when the PDCCH is SIB1, the terminal device uses the format of the first system information block to parse it, or when the PDCCH is the first system information block, the terminal device uses the format of SIB1 to parse it, resulting in the terminal device being unable to correctly parse the first system information block or SIB1.

[0118] In some embodiments, to prevent the terminal device from incorrectly parsing the SSB, the method further includes:

[0119] The terminal device receives the first indication information sent by the network device, and the first indication information is used to indicate that the coreset and SS indicated by the SSB of the first cell are the coreset and SS of the first system information block, or the coreset and SS indicated by the SSB of the first cell are the coreset and SS of SIB1 of the first cell.

[0120] In some embodiments, the first indication information is sent through the master information block (MIB) of the first cell, that is, the terminal device is notified in the MIB whether PDCCH-ConfigSIB1 indicates the coreset and SS of the PDCCH of SIB1 or the coreset and SS of the PDCCH of the first system information block.

[0121] In some embodiments, the first indication information is sent through the PDCCH or downlink control information (DCI) of SIB1 of the first cell, that is, the terminal device is notified by scheduling the PDCCH or DCI of SIB1 whether PDCCH-ConfigSIB1 indicates the coreset and SS of the PDCCH of SIB1 or the coreset and SS of the PDCCH of the first system information block.

[0122] In some embodiments, the first indication information is sent through the PDCCH or DCI of the first system information block, that is, the terminal device is notified by scheduling the PDCCH or DCI of the first system information block whether PDCCH-ConfigSIB1 indicates the coreset and SS of the PDCCH of SIB1, or the coreset and SS of the PDCCH of the first system information block.

[0123] Therefore, the terminal device receives the first indication information sent by the network device, and can know according to the first indication information whether the PDCCH-ConfigSIB1 in the SSB (MIB) of the first cell indicates the coreset and SS of the PDCCH of the first system information block, or the coreset and SS of the PDCCH of SIB1, so that the SSB can be parsed in the correct format. When the PDCCH-ConfigSIB1 in the SSB (MIB) of the first cell indicates the coreset and SS of the PDCCH of the first system information block, the WUS configuration information contained therein can be correctly parsed.

[0124] The following describes a case where the WUS configuration information is sent by the network device through a second cell different from the first cell.

[0125] In some embodiments, when the WUS configuration information is sent through the second cell, the WUS configuration information is included in the first information sent by the network device in the second cell. The network device sends the first information in the second cell and uses the first information to carry the WUS configuration information related to the first cell, thereby sending the WUS configuration information to the terminal device through the first information.

[0126] In some embodiments, the first information includes more than one first cells, and the more than one first cells have the same WUS configuration information.

[0127] In some embodiments, the first information includes a cell identifier and / or frequency information of at least one first cell, and WUS configuration information associated with at least one first cell. A first cell can be uniquely identified based on the identifier and / or frequency information of a first cell. In the embodiments of the present application, the first cell refers to a cell, but does not specifically refer to a specific cell. That is, any cell can be referred to as a first cell.

[0128] In some embodiments, the cell identifier includes, for example, a physical cell identifier (PCI) and / or a cell global identifier (CGI) and / or a cell identity (Cell Identity).

[0129] In some embodiments, the frequency information includes, for example, frequency information of a synchronization signal block (SSB) of the first cell and / or frequency information of an initial bandwidth part (BWP) and / or frequency information of a carrier. The frequency information of the SSB may include the absolute frequency of the SSB and / or the absolute frequency of point A; the frequency information of the initial BWP may include the location and bandwidth of the BWP; and the frequency information of the carrier may include the frequency of the carrier, etc.

[0130] In some embodiments, the first information includes one or more groups of correspondences, and each group of correspondences includes a cell identifier and / or frequency information of a first cell and WUS configuration information associated with the first cell. For example, one group of correspondences includes a CGI of a first cell and WUS configuration information associated with the first cell, and the terminal device can uniquely identify a first cell through the CGI. For another example, one group of correspondences includes the PCI and frequency information of a first cell, and WUS configuration information associated with the first cell, and the terminal device can uniquely identify a first cell through the PCI and frequency information. Thus, the terminal device can determine the WUS configuration information of one or more first cells based on one or more groups of correspondences in the first information.

[0131] In some embodiments, the first information may be system information, such as SIB3, SIB4, or SIB5. In this case, the WUS configuration information associated with the first cell is indicated by the system information of the second cell.

[0132] In some embodiments, the first information may be at least one of the following: an RRC reconfiguration message; an RRC release message; an RRC reject message; an RRC resume message; or an RRC setup message. In this case, the RRC message sent by the second cell indicates WUS configuration information associated with the first cell.

[0133] In some embodiments, after receiving the first information or WUS configuration information, the terminal device stores the content of the first information or WUS configuration information. In addition, the terminal device may store the updated content of the first information or WUS configuration information when the content of the first information or WUS configuration information is updated.

[0134] In some embodiments, the network device also indicates the configuration of a timer associated with the WUS configuration information.

[0135] In some embodiments, the method further includes: the terminal device receiving a configuration of a timer associated with the WUS configuration information, wherein the configuration of the timer is used to indicate a valid time of the WUS configuration information associated with the second timer.

[0136] In some embodiments, the configuration of the timer is included in the first information. That is, the first information also includes the configuration of the timer associated with the WUS configuration information included in the first information.

[0137] In some embodiments, the configuration of the timer is included in the WUS configuration information. That is, the WUS configuration information includes the configuration of the timer associated with the WUS configuration information.

[0138] In some embodiments, when the first information includes WUS configuration information associated with more than one first cell, the configurations of the timers associated with different WUS configuration information associated with the first cells may be the same or different.

[0139] In some embodiments, when the WUS configuration information associated with different first cells has the same configuration of the associated timer, the network device can configure the same timer configuration for more than one WUS configuration information contained in the first information, or can configure the timer configuration for each WUS configuration information separately.

[0140] In some embodiments, when the configurations of the timers associated with WUS configuration information associated with different first cells are different, the network device configures the timer configurations for the more than one WUS configuration information included in the first information respectively.

[0141] In some embodiments, the method further comprises:

[0142] In a case where the first information or the WUS configuration information includes the configuration of the timer associated with the WUS configuration information, after receiving the WUS configuration information, the terminal device starts the second timer according to the configuration of the timer associated with the WUS configuration information.

[0143] In some embodiments, the method further includes: when the second timer times out, the terminal device releases or deletes the WUS configuration information or considers the WUS configuration information associated with the second timer to be invalid.

[0144] In some embodiments, the terminal device may start the same timer for WUS configuration information associated with different first cells. For example, if the timer configurations of more than one WUS configuration information are the same, the terminal device starts one timer; when the timer expires, the terminal device releases or deletes the more than one WUS configuration information associated with the timer.

[0145] In some embodiments, the terminal device may start different timers for different WUS configuration information associated with the first cell. For example, if the timer configurations of more than one WUS configuration information are the same or different, the terminal device starts a timer for each WUS configuration information; when a timer expires, the terminal device releases or deletes the WUS configuration information associated with the expired timer.

[0146] In the above embodiment, the sending of WUS configuration information is described, and the WUS configuration information can be sent by the network device through the first cell or the second cell. In the following embodiment, the terminal device sending the wake-up signal according to the WUS configuration information in 402 will be described.

[0147] In some embodiments, the sending of the wake-up signal by the terminal device includes triggering or initiating the wake-up signal, resending or retransmitting the wake-up signal, and stopping the sending of the wake-up signal.

[0148] In some embodiments, the terminal device triggers or initiates the sending of the wake-up signal in at least one of the following situations:

[0149] The terminal device initiates or performs a cell selection or cell reselection process. For example, during the cell selection or reselection process, the terminal device searches for a first cell. In order to determine whether the first cell is a suitable cell, the terminal device needs to obtain the SIB1 of the first cell to obtain parameters related to the cell selection or reselection. Therefore, in this case, the terminal device sends a WUS to request the first cell to send the SIB1.

[0150] The terminal device returns to the coverage of the first cell;

[0151] The terminal device receives second indication information indicating a change in the system information of the first cell, for example, the second indication information may be a paging message;

[0152] When the terminal device initiates an initial access or random access procedure or before initiating the initial access or random access procedure, for example, the terminal device resides in the second cell and will initiate an initial access or random access procedure in the first cell. The terminal device needs to obtain the SIB1 of the first cell to obtain the configuration of the relevant common channel of the initial access or random access procedure. Therefore, in this case, the terminal device sends a WUS to request the first cell to send SIB1;

[0153] The terminal device does not have a stored or valid SIB1 of the first cell. For example, after a preset time (for example, 3 hours) starting from the moment when the terminal device successfully confirms that the SIB1 of the first cell is valid or receives the SIB1 of the first cell, the terminal device considers that the SIB1 of the first cell is no longer valid or invalid. Therefore, in this case, the terminal device sends a WUS to request the first cell to send SIB1;

[0154] The terminal device wants to obtain the SIB1 of the first cell, and the first cell is a cell that supports or uses on-demand SIB1, or the first cell has or supports on-demand SIB1 transmission, or the WUS configuration information related to the first cell is provided by the first cell and / or the second cell. For the content related to the second cell, please refer to the previous embodiment and will not be repeated here.

[0155] In some embodiments, the terminal device resends or retransmits the wake-up signal in at least one of the following situations:

[0156] The SIB1 of the first cell is not received within a time window, for example, the starting point of the time window is the first symbol or time slot after the WUS is sent, and the length of the time window may be predefined or configured by the network device;

[0157] A first timer times out; the first timer is, for example, a timer related to retransmission or retransmission of a wake-up signal, for example, the terminal device starts the first timer in the first symbol or time slot after sending a WUS, and / or the length of the first timer may be predefined or configured by a network device, and / or the terminal device stops the first timer upon receiving the SIB1 of the first cell or receiving a WUS-related confirmation;

[0158] The maximum number of WUS transmissions has not been reached;

[0159] An acknowledgement (ACK) associated with a sent WUS is not received from the network device, for example, the WUS is used to request the SIB1 of the first cell.

[0160] In some embodiments, the terminal device stops sending the wake-up signal in at least one of the following situations:

[0161] receiving SIB1 of the first cell;

[0162] receiving an ACK associated with a sent WUS from the network device, for example, the WUS is used to request SIB1 of the first cell;

[0163] The maximum number of WUS transmissions has been reached.

[0164] In some embodiments, the wake-up signal is sent once. In this case, the terminal device only sends the wake-up signal once. After the terminal device triggers or initiates the sending of the wake-up signal and sends the wake-up signal once, the wake-up signal is not retransmitted or resent, regardless of whether the conditions for the terminal device to retransmit or resent the wake-up signal described in the above embodiments are met.

[0165] In some embodiments, the maximum number of WUS transmissions may be predefined or configured by a network device, and the maximum number may be the same or different for different first cells.

[0166] In some embodiments, the terminal device obtains the WUS configuration information during the process of WUS being triggered or initiated, or obtains the WUS configuration information before WUS is triggered or initiated.

[0167] In some embodiments, the WUS-related confirmation may be included in a Random Access Response (DCI).

[0168] Through the above embodiments, the terminal device sends WUS to request SIB1 or stops sending WUS under appropriate conditions / circumstances, which helps save WUS sending resources and is also beneficial to saving energy consumption of network devices detecting WUS and energy consumption of terminal devices sending WUS.

[0169] In some embodiments, the terminal device may send the WUS in a first cell, and may also send the WUS in a second cell different from the first cell.

[0170] In some embodiments, the WUS configuration information includes the WUS configuration information sent by the terminal device in the first cell, and / or the WUS configuration information sent by the terminal device in the second cell, where the second cell is a cell different from the first cell. The content related to the second cell can refer to the previous embodiments and will not be repeated here.

[0171] In some embodiments, when the WUS configuration information includes configuration information of a WUS sent by the terminal device in the first cell, in 402 , the terminal device may send a WUS in the first cell according to the WUS configuration information to request the first cell to send SIB1.

[0172] In some embodiments, when the WUS configuration information includes configuration information of a WUS sent by the terminal device in the second cell, in 402 , the terminal device may send a WUS in the second cell according to the WUS configuration information to request the first cell to send SIB1.

[0173] In some embodiments, the WUS configuration information is determined by the first cell, or the WUS configuration information is determined by a second cell different from the first cell. In this case, interactions related to the WUS configuration information may be involved between different cells.

[0174] In some embodiments, the WUS configuration information is determined by the second cell. The following situations may occur:

[0175] Case 1: The WUS configuration information is sent by the network device through the second cell, and the terminal device sends WUS in the second cell. In this case, no interaction related to the WUS configuration information is performed between the first cell and the second cell. For example, Figure 5 is a schematic diagram of a scenario related to the interaction between cells in an embodiment of the present application. As shown in Figure 5, taking the first cell as an NES cell and the second cell as an anchor cell as an example, if the WUS configuration information (WUS config) is determined by the anchor cell and sent through the anchor cell, and the terminal device sends WUS in the anchor cell, no interaction related to the WUS configuration is performed between the anchor cell and the NES cell.

[0176] Case 2: The WUS configuration information is sent by the network device through the second cell, and the terminal device sends WUS in the first cell. In this case, the second cell notifies the first cell of the WUS configuration information. For example, Figure 6 is another schematic diagram of a scenario related to the interaction between cells in an embodiment of the present application. As shown in Figure 6, taking the first cell as an NES cell and the second cell as an anchor cell as an example, if the WUS configuration information (WUS config) is determined by the anchor cell and sent through the anchor cell, and the terminal device sends WUS in the NES cell, the anchor cell notifies the NES cell of the WUS configuration information, that is, the anchor cell and the NES cell perform interaction related to the WUS configuration.

[0177] Case three: The WUS configuration information is sent by the network device through the first cell, and the terminal device sends WUS in the first cell. In this case, the second cell notifies the first cell of the WUS configuration information. For example, Figure 7 is another schematic diagram of a scenario related to the interaction between cells in an embodiment of the present application. As shown in Figure 7, taking the first cell as an NES cell and the second cell as an anchor cell as an example, if the WUS configuration information (WUS config) is determined by the anchor cell and sent through the NES cell, and the terminal device sends WUS in the NES cell, the anchor cell notifies the NES cell of the WUS configuration information, that is, the anchor cell and the NES cell perform interaction related to the WUS configuration.

[0178] Case 4: The WUS configuration information is sent by the network device through the first cell, and the terminal device sends WUS in the second cell. In this case, the second cell notifies the first cell of the WUS configuration information. For example, Figure 8 is a schematic diagram of a scenario related to the interaction between cells in an embodiment of the present application. As shown in Figure 8, taking the first cell as an NES cell and the second cell as an anchor cell as an example, if the WUS configuration information (WUS config) is determined by the anchor cell and sent through the NES cell, and the terminal device sends WUS in the anchor cell, the anchor cell notifies the NES cell of the WUS configuration information, that is, the anchor cell and the NES cell perform interaction related to the WUS configuration.

[0179] In some embodiments, the WUS configuration information is determined by the first cell. The following situations may exist:

[0180] Case 5: The WUS configuration information is sent by the network device through the second cell, and the terminal device sends WUS in the second cell. In this case, the first cell notifies the second cell of the WUS configuration information. For example, Figure 9 is another schematic diagram of a scenario related to the interaction between cells in an embodiment of the present application. As shown in Figure 9, taking the first cell as an NES cell and the second cell as an anchor cell as an example, if the WUS configuration information (WUS config) is determined by the NES cell and sent through the anchor cell, and the terminal device sends WUS in the anchor cell, the NES cell notifies the anchor cell of the WUS configuration information, that is, the anchor cell and the NES cell perform interaction related to the WUS configuration.

[0181] Case six: When the WUS configuration information is sent by the network device through the second cell, and the terminal device sends WUS in the first cell. In this case, the first cell notifies the second cell of the WUS configuration information. For example, Figure 10 is another schematic diagram of a scenario related to the interaction between cells in an embodiment of the present application. As shown in Figure 10, taking the first cell as an NES cell and the second cell as an anchor cell as an example, if the WUS configuration information (WUS config) is determined by the NES cell and sent through the anchor cell, and the terminal device sends WUS in the NES cell, the NES cell notifies the anchor cell of the WUS configuration information, that is, the anchor cell and the NES cell perform interaction related to the WUS configuration.

[0182] Case seven: The WUS configuration information is sent by the network device through the first cell, and the terminal device sends WUS in the first cell. In this case, no interaction related to the WUS configuration information is performed between the first cell and the second cell. For example, Figure 11 is a schematic diagram of another scenario related to the interaction between cells in an embodiment of the present application. As shown in Figure 11, taking the first cell as an NES cell and the second cell as an anchor cell as an example, if the WUS configuration information (WUS config) is determined by the NES cell and sent through the NES cell, and the terminal device sends WUS in the NES cell, no interaction related to the WUS configuration is performed between the anchor cell and the NES cell.

[0183] Case eight: When the WUS configuration information is sent by the network device through the first cell, and the terminal device sends WUS in the second cell. In this case, the first cell notifies the second cell of the WUS configuration information. For example, Figure 12 is another schematic diagram of a scenario related to the interaction between cells in an embodiment of the present application. As shown in Figure 12, taking the first cell as an NES cell and the second cell as an anchor cell as an example, if the WUS configuration information (WUS config) is determined by the NES cell and sent through the NES cell, and the terminal device sends WUS in the anchor cell, the NES cell notifies the anchor cell of the WUS configuration information, that is, the anchor cell and the NES cell perform interaction related to the WUS configuration.

[0184] In some embodiments, the WUS configuration information may be included in an XnAP message between the first cell and the second cell, and the XnAP message may include at least one of the following: Xn setup request (XN SETUP REQUEST) or Xn setup response (XN SETUP RESPONSE) or NR-RAN node configuration update (NG-RAN node Configuration Update) or NR-RAN node configuration update confirmation (NG-RAN node Configuration Update) or cell activation request (CELL ACTIVATION REQUEST) or cell activation response (CELL ACTIVATION RESPONSE) or access and mobility indication (ACCESS AND MOBILITY INDICATION) and other messages.

[0185] As can be seen from the above embodiment, in the information receiving and sending method of the embodiment of the present application, the terminal device receives the WUS configuration information related to the first cell sent by the network device. As a result, the terminal device can send a WUS signal according to the WUS configuration information to request the first cell to send SIB1 (also known as on-demand SIB1), thereby helping the terminal device to determine whether the first cell can be used as a serving cell based on the received SIB1 of the first cell, or use the public configuration of the first cell provided in the SIB1 to perform a subsequent random access process or receive paging, etc. The method is simple and easy to implement;

[0186] In addition, the first cell can send SIB1 upon receiving a request from the terminal device, which is beneficial for saving energy of the network device.

[0187] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0190] Embodiments of the second aspect

[0191] An embodiment of the present application provides a method for receiving and sending information, which is described from the perspective of a network device.

[0192] FIG13 is another schematic diagram of the information receiving and sending method according to an embodiment of the present application. The method is applied to a network device. As shown in FIG13 , the method includes:

[0200] In some embodiments, in some embodiments, the terminal device includes a terminal device in an RRC idle (RRC_Idle) state or an RRC inactive (RRC_Inactive) state.

[0201] In some embodiments, the first cell is a cell that supports or uses on-demand SIB1, which may also be referred to as an NES cell in the following embodiments.

[0202] In some embodiments, in 1301, the wake-up signal (WUS) configuration information includes information related to WUS, for example, at least one of the following information: time resources and / or frequency resources of WUS; index of WUS sequence; maximum number of WUS transmission times; WUS transmission power ramping step; expected WUS receiving power.

[0203] In some embodiments, at least one of the following WUS-related information is predefined: WUS time resource and / or frequency resource; WUS sequence index; maximum WUS transmission times; WUS transmit power ramping step; and expected WUS receive power. Thus, by predefining at least one WUS-related information, the remaining WUS-related information can be configured via WUS configuration information, thereby saving bits in signaling for transmitting the WUS configuration information.

[0204] In some embodiments, the information related to the WUS includes time resources and / or frequency resources of the WUS, and there is a predefined correspondence between the time resources and / or frequency resources of the WUS and the position of the SSB of the first cell.

[0205] In some embodiments, the correspondence between the time resources and / or frequency resources of the WUS and the position of the SSB of the first cell includes: the time difference between the time domain resources of the WUS and the time domain resources of the SSB is a predefined offset value, for example, the predefined offset value is, for example, N symbols or N slots; and / or

[0206] The difference between the minimum or maximum resource block (RB) index of the WUS and the minimum or maximum RB index of the SSB is a predefined integer, for example, the difference between the minimum or maximum RB index of the WUS and the minimum or maximum RB index of the SSB is X (X is a predefined integer) RBs; or, the difference between the minimum or maximum subcarrier (Subcarrier) index of the WUS and the minimum or maximum subcarrier index of the SSB is a predefined integer; or, the difference between the minimum or maximum subband (Subband) index of the WUS and the minimum or maximum subband index of the SSB is a predefined integer, etc.

[0207] In some embodiments, the WUS configuration information includes PRACH-related information, for example, at least one of the following information: RACH general configuration (RACH-ConfigGeneric), SSB index (SSB-Index), random access preamble index (ra-PreambleIndex), random access moment (ra-Occasion) information, PRACH root sequence index, PRACH subcarrier spacing, etc.

[0208] In some embodiments, the WUS configuration information is sent by the network device through the first cell (or in the first cell). For details about sending the WUS configuration information through the first cell, please refer to the embodiment of the first aspect, which is incorporated herein and will not be repeated here.

[0209] In some embodiments, the WUS configuration information is carried by a synchronization information block (SSB) of the first cell.

[0210] In some embodiments, the WUS configuration information is carried by a first system information block, and a control resource set (coreset) and a search space (SS) of a physical downlink control channel (PDCCH) of the first system information block are indicated by a synchronization information block (SSB) of the first cell. For example, the coreset and SS of the PDCCH of the first system information block are indicated by PDCCH-ConfigSIB1 in the SSB (MIB).

[0211] When the first cell is an NES cell, the PDCCH-ConfigSIB1 in the SSB (MIB) of the first cell indicates the coreset and SS of the PDCCH of the first system information block, but when the first cell is not an NES cell, the PDCCH-ConfigSIB1 in the SSB (MIB) of the first cell indicates the coreset and SS of the PDCCH of SIB1. If the terminal device does not know whether the first cell is an NES cell, the terminal device also does not know whether the PDCCH-ConfigSIB1 in the SSB (MIB) of the first cell indicates the coreset and SS of the PDCCH of the first system information block or the coreset and SS of the PDCCH of SIB1. Therefore, after the terminal device receives the PDCCH indicated by the SSB (MIB) of the first cell, it may use an incorrect format to parse the PDCCH. For example, when the PDCCH is SIB1, the terminal device uses the format of the first system information block to parse it, or when the PDCCH is the first system information block, the terminal device uses the format of SIB1 to parse it, resulting in the terminal device being unable to correctly parse the first system information block or SIB1.

[0212] In some embodiments, to prevent the terminal device from incorrectly parsing the SSB, the method further includes:

[0213] The network device sends first indication information to the terminal device, and the first indication information is used to indicate that the coreset and SS indicated by the SSB of the first cell are the coreset and SS of the first system information block, or that the coreset and SS indicated by the SSB of the first cell are the coreset and SS of SIB1 of the first cell.

[0214] For the content related to the first indication information, please refer to the embodiment of the first aspect. The above content is incorporated here and will not be repeated here.

[0215] In some embodiments, the WUS configuration information is sent by the network device via a second cell (or in the second cell), where the second cell is a cell different from the first cell, for example, the second cell is an anchor cell providing coverage or a neighboring cell of the first cell. The above contents related to sending the WUS configuration information via the second cell in the first aspect of the embodiments are incorporated herein and are not repeated here.

[0216] In some embodiments, the wake-up signal received by the network device includes a wake-up signal triggered or initiated by a terminal device, or a wake-up signal retransmitted or retransmitted by the terminal device. For details related to the triggering or initiation of the sending of the wake-up signal by the terminal device, and the retransmission or retransmission of the wake-up signal by the terminal device, please refer to the embodiments of the first aspect, which are incorporated herein and are not repeated here.

[0217] In some embodiments, the WUS configuration information is determined by the first cell, or the WUS configuration information is determined by a second cell different from the first cell. In this case, interactions related to the WUS configuration information between different cells may be involved. For details related to interactions related to the WUS configuration information between different cells, please refer to the embodiments of the first aspect, which are incorporated herein and are not repeated here.

[0218] According to the above embodiment, the network device sends WUS configuration information related to the first cell to the terminal device, thereby enabling the terminal device to send a WUS signal according to the WUS configuration information to request the first cell to send SIB1 (also referred to as on-demand SIB1), thereby helping the terminal device determine, based on the received SIB1 of the first cell, whether the first cell can be used as a serving cell, or use the public configuration of the first cell provided in the SIB1 to perform a subsequent random access process or receive paging, etc. The method is simple and easy to implement;

[0219] In addition, the first cell can send SIB1 upon receiving a request from the terminal device, which is beneficial for saving energy of the network device.

[0220] The implementation and glossary of this embodiment are similar to those of the embodiment of the first aspect of this application. The above related contents are incorporated herein and will not be repeated here.

[0221] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0222] It is worth noting that the above only describes the steps related to the present application, but the present application is not limited thereto. The data receiving method of the present application may also include other steps, and for the specific content of these steps, reference may be made to the relevant art.

For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

Therefore, for the implementation of the information receiving and sending device, please refer to the implementation of the information sending method in the embodiment of the third aspect provided by the present application, and the repeated parts will not be repeated. As used below, the term "unit" or "module" can be a combination of software and / or hardware that implements a predetermined function. Although the system described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceived.

[0298] The third receiving unit 1502 is configured to receive a wake-up signal sent by the terminal device according to the wake-up signal configuration information.

[0299] According to the above embodiment, the network device sends WUS configuration information related to the first cell to the terminal device, thereby enabling the terminal device to send a WUS signal according to the WUS configuration information to request the first cell to send SIB1 (also referred to as on-demand SIB1), thereby helping the terminal device determine, based on the received SIB1 of the first cell, whether the first cell can be used as a serving cell, or use the public configuration of the first cell provided in the SIB1 to perform a subsequent random access process or receive paging, etc. The method is simple and easy to implement;

[0300] In addition, the first cell can send SIB1 upon receiving a request from the terminal device, which is beneficial for saving energy of the network device.

[0301] In some embodiments, in some embodiments, the terminal device includes an idle / inactive terminal device.

[0302] In some embodiments, the first cell is a cell that supports or uses on-demand SIB1, which may also be referred to as an NES cell in the following embodiments.

[0303] In some embodiments, the wake-up signal (WUS) configuration information includes information related to the WUS, for example, at least one of the following information: time resources and / or frequency resources of the WUS; index of the WUS sequence; maximum number of WUS transmissions; WUS transmission power ramping step; and expected WUS reception power.

[0304] In some embodiments, at least one of the following WUS-related information is predefined: WUS time resource and / or frequency resource; WUS sequence index; maximum WUS transmission times; WUS transmit power ramping step; and expected WUS receive power.

[0305] In some embodiments, the information related to the WUS includes time resources and / or frequency resources of the WUS, and there is a predefined correspondence between the time resources and / or frequency resources of the WUS and the position of the SSB of the first cell.

[0306] In some embodiments, the correspondence between the time resources and / or frequency resources of the WUS and the position of the SSB of the first cell includes: the time difference between the WUS and the SSB is a predefined offset value, for example, the predefined offset value is, for example, N symbols or N slots; and / or

[0308] In some embodiments, the WUS configuration information is sent by the network device through the first cell. For details about sending the WUS configuration information through the first cell, please refer to the embodiment of the third aspect, which is incorporated herein and will not be repeated here.

For example, the coreset and SS of the PDCCH of the first system information block are indicated by PDCCH-ConfigSIB1 in the SSB (MIB).

[0311] When the first cell is an NES cell, the PDCCH-ConfigSIB1 in the SSB (MIB) of the first cell indicates the coreset and SS of the PDCCH of the first system information block, but when the first cell is not an NES cell, the PDCCH-ConfigSIB1 in the SSB (MIB) of the first cell indicates the coreset and SS of the PDCCH of SIB1. If the terminal device does not know whether the first cell is an NES cell, the terminal device also does not know whether the PDCCH-ConfigSIB1 in the SSB (MIB) of the first cell indicates the coreset and SS of the PDCCH of the first system information block or the coreset and SS of the PDCCH of SIB1. Therefore, after the terminal device receives the PDCCH indicated by the SSB (MIB) of the first cell, it may parse the PDCCH in an incorrect format. For example, when the PDCCH is SIB1, the terminal device parses it in the format of the first system information block, or when the PDCCH is the first system information block, the terminal device parses it in the format of SIB1, resulting in the terminal device being unable to correctly parse the first system information block or SIB1.

[0312] In some embodiments, in order to prevent the terminal device from incorrectly parsing the SSB, the apparatus further includes:

[0313] The fifth sending unit 1503 (not shown) is used by the network device to send the first indication information to the terminal device, wherein the first indication information is used to indicate that the coreset and SS indicated by the SSB of the first cell are the coreset and SS of the first system information block, or that the coreset and SS indicated by the SSB of the first cell are the coreset and SS of the SIB1 of the first cell.

[0315] In some embodiments, the WUS configuration information is sent by the network device via a second cell, where the second cell is a cell different from the first cell, for example, the second cell is an anchor cell providing coverage or a neighboring cell of the first cell. The above contents related to sending the WUS configuration information via the second cell are incorporated herein and are not repeated here.

[0316] In some embodiments, the wake-up signal received by the network device includes a wake-up signal triggered or initiated by a terminal device, or a wake-up signal retransmitted or retransmitted by the terminal device. For details related to the triggering or initiation of the sending of the wake-up signal by the terminal device, and the retransmission or retransmission of the wake-up signal by the terminal device, please refer to the embodiments of the third aspect, which are incorporated herein and are not repeated here.

[0317] In some embodiments, the WUS configuration information is determined by the first cell, or the WUS configuration information is determined by a second cell different from the first cell. In this case, interactions related to the WUS configuration information between different cells may be involved. For details related to interactions related to the WUS configuration information between different cells, please refer to the embodiments of the third aspect, which are incorporated herein and are not repeated here.

[0318] As can be seen from the above embodiment, the network device sends WUS configuration information related to the first cell to the terminal device. As a result, the terminal device can send a WUS signal according to the WUS configuration information to request the first cell to send SIB1 (also known as on-demand SIB1), thereby helping the terminal device determine whether to use the first cell as a serving cell or use the public configuration of the first cell provided in the SIB1 for subsequent random access procedures or paging reception, etc. The method is simple and easy to implement.
