[0002] In communication systems, signals or channels received or transmitted by a terminal can be triggered by other signals. For example, a downlink signal or channel received by the terminal may be triggered by a single signal, and an uplink signal or channel transmitted by the terminal may also be triggered by a single signal. However, in related technologies, the signals that trigger these signals or channels are often signals sent by network-side devices, i.e., downlink signals, such as the downlink wake-up signal (WUS).

[0059] Figure 1This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network-side device 12.

Network-side equipment 12 may include access network equipment or core network equipment, wherein access network equipment may also be referred to as Radio Access Network (RAN) equipment, radio access network function, or radio access network unit.

The term "base station" can be any suitable term in the field, such as "station" or any other appropriate term in the relevant field, as long as the same technical effect is achieved. The term "base station" is not limited to specific technical terms. It should be noted that the embodiments of this application only use the base station in the NR system as an example for introduction, and do not limit the specific type of base station.

[0060] Core network equipment, also known as core network nodes, core network functions, or core network elements, includes, but is not limited to, at least one of the following: Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), and Binding Support.

If the name of the core network equipment mentioned in the embodiments of this application changes in subsequent protocol versions (such as 6G), it is also within the scope of protection of this application.

[0061] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0062] Taking 5G systems as an example, the main scenarios for 5G systems include Enhanced Mobile Broadband (eMBB), Massive Machine Type Communication (mMTC), and Ultra Reliable & Low Latency Communication (URLLC). These scenarios place demands on the system to achieve high reliability, low latency, high bandwidth, and wide coverage. To adapt to diverse scenarios and service needs, duplex technology has been enhanced.

[0063] In 5G systems, configuring full-duplex operation can significantly improve the latency and coverage performance of time division duplex (TDD) systems. For example, non-overlapping sub-band full-duplex can improve transmission latency and enhance coverage.

[0064] For example, for a downlink (DL) or uplink (UL) timeslot, the network-side device configures the DL bandwidth part (BWP) for the terminal; for a UL timeslot, the network-side device configures the ULBWP for the terminal. For example, timeslots 1 and 4. In a full-duplex scenario, as shown... Figure 2 and Figure 3 The following is a case study:

[0065] Case 1: Configure DL BWP, i.e. Figure 2 Slot 1 in the middle;

[0066] Case 2: Configure DL BWP and UL subband, i.e. Figure 2 slot 2 in

[0067] Case 3: Configure UL BWP, i.e. Figure 3 Slot 4 in the middle;

[0068] Case 4: Configure UL BWP and DL subband, i.e. Figure 3 Slot 5 in the middle.

[0069] For Subband Full Duplex (SBFD) operation, an SBFD subband consists of one resource block (RB) or a continuous set of RBs with the same transmission direction. The time unit (e.g., slot or symbol) used by network-side devices for SBFD operation can be referred to as an SBFD time unit (e.g., slot or symbol).

[0070] In some systems, network-side devices are full-duplex, such as... Figure 4 As shown, network-side devices can send and receive simultaneously, while terminal-side devices can only use half-duplex mode, meaning they can only send or receive at any given time. For full-duplex terminal-side devices, both network-side devices and terminals can send and receive simultaneously.

[0071] For full-duplex operation on the terminal side, a larger guard band (GB) may be needed to suppress self-interference, such as... Figure 5 As shown.

[0072] It should be noted that the above example uses a 5G system. The method provided in this application can be applied to 5G systems, as well as 6G or 7G systems, and is not limited thereto.

[0073] The signal transmission method, receiving method, apparatus, terminal, and network-side equipment provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0074] Please see Figure 6 , Figure 6 This is a flowchart of a signal transmission method provided in an embodiment of this application, such as... Figure 6 As shown, it includes the following steps:

[0075] Step 601: The terminal determines a first resource group, the first resource group including at least one first resource, the first resource being a transmission resource or a retransmission resource of a first signal;

[0076] Step 602: The terminal sends a first signal in the first resource group, the first signal being used for at least one of the following:

[0077] Triggering the transmission of a common downlink signal or a common downlink channel;

[0078] Triggering the transmission of a common uplink signal or a common uplink channel;

[0079] Trigger the transmission of on-demand signals or on-demand channels.

[0080] The aforementioned terminal may determine the first resource group in an idle or inactive state, or in other non-connected states, such as the standby state introduced in 6G or future mobile communication systems, the state after Radio Resource Control (RRC) release and before random access, or other non-connected states before random access.

[0081] The first signal mentioned above can be WUS, or other signals, without limitation, such as other signals defined in the protocol for triggering the transmission of common downlink signals or common downlink channels, or other signals for triggering the transmission of common uplink signals or common uplink channels, or other signals for triggering the transmission of on-demand signals or on-demand channels.

[0082] The aforementioned common downlink signal or common downlink channel may include at least one of the following:

[0083] Synchronization Signal Block (SSB), System Information Block (SIB) 1, Other System Information (OSI), signals or channels corresponding to Control Resource Set (CORESET) #0, Paging, Paging Physical Downlink Control Channel (PDCCH), Paging Physical Downlink Shared Channel (PDSCH), Common Downlink Reference Signal (DLRS), etc.

[0084] In this application embodiment, SSB and Synchronization Signal (SS) or Physical Broadcast Channel (PBCH) blocks can be used interchangeably or with other names to represent any module containing at least a portion of a synchronization signal, broadcast signal, or other downlink broadcast signal or its scheduling channel.

[0085] The aforementioned common uplink signal or common uplink channel may include at least one of the following:

[0086] Physical Random Access Channel (PRACH), Configuration Grant Physical Uplink Shared Channel (CG PUSCH), Sounding Reference Signal (SRS), Common UL Reference Signal (UL RS), etc.

[0087] The transmission of the aforementioned trigger signal or channel can also be referred to as the transmission of the wake-up or activation signal or channel.

[0088] Taking the first signal as WUS as an example, the first resource is the Wake-up Signal Opportunity (WUS Occasion, WO), which refers to the time and frequency resources required to send a WUS. The first resource group is a WO group or a WO set.

[0089] The aforementioned first resource group can be a specific resource group among multiple resource groups, such as resource groups of different types, for example... Figure 7 As shown, Figure 7 In the UE section, Rep indicates repeated transmission, with Rep.1 to Rep.4 representing four transmissions on four WOs respectively. UL SB indicates uplink sub-band (SB). Legacy UE refers to a traditional terminal, such as a terminal that does not support enhanced duplex. Xdd indicates cross-segmented duplex (XDD), which includes the following three resource groups:

[0090] Resource Group 1 (i.e.) Figure 7 In case 1), the resources in this resource group (such as WO) are only on the UL time unit (such as time slot);

[0091] Resource Group Two (i.e.) Figure 7 In case 2), the resources in this resource group (such as WO) are only on the UL subband (such as the uplink subband within the downlink time unit);

[0092] Resource Group 3 (i.e.) Figure 7 In case 3), the resource group (such as WO group) appears in two types of resources (such as WO), that is, the resource can be on UL time slot or on UL subband.

[0093] In some implementations, for the three resource groups mentioned above, if the first resource of the three resource groups includes the same resource (such as WO), then the first signal sequence resources used by the different resource groups are different on these first resources.

[0094] The aforementioned terminal sending a first signal on the first resource group means sending a first signal to the network-side device on the first resource group, i.e., the first signal is an uplink signal. Furthermore, the first signal can be sent separately on each first resource in the first resource group. If the first resource group includes multiple first resources, the first signal can be repeatedly transmitted on multiple first resources.

[0095] Among them, WUS repeated transmission can refer to repeated transmissions performed during each initial transmission or retransmission of the first signal.

[0096] In this embodiment of the application, the above steps can be used to send a first signal in the first resource group determined by the terminal to trigger the transmission of the corresponding signal or channel, thereby improving the communication performance of the terminal.

[0097] As an optional implementation, the terminal determines the first resource group by:

[0098] The terminal determines the type of the first resource group based on the first information;

[0099] The first information includes at least one of the following:

[0100] The terminal's capability information, downlink signal measurement results, first signal sequence information, first signal transmission resource information, information of the signal or channel triggered by the first signal, and first downlink information received by the terminal;

[0101] The capability information is used to indicate whether the terminal supports enhanced full-duplex.

[0102] The first downlink information is used to configure the transmission resources or retransmission resources of the first signal.

[0103] The term "enhanced duplex" can also refer to enhanced duplex, enhanced duplex mode, cross-segmented duplex (XDD), enhanced full-duplex, or enhanced full-duplex mode. Enhanced duplex supports at least one of the following:

[0104] Supports uplink subband within downlink time units;

[0105] Supports downlink subbands in the uplink time unit;

[0106] It supports both uplink and downlink subband transmission on a flexible time unit.

[0107] Based on the aforementioned capability information, the terminal selects the first resource group supported by the terminal. For example, if the terminal supports enhanced duplex, it can select... Figure 7 The terminal selects any of the resource groups shown, or if the terminal does not support enhanced duplex. Figure 7 The resource group shown in case 1.

[0108] The aforementioned capability information can support the determination of the first resource group for terminals with different duplex capabilities, enabling the terminal to select the resource group it supports based on its own capability information, thereby improving the transmission performance of the first signal.

[0109] The aforementioned downlink signal is a signal sent from the network-side device to the terminal. The measurement result of the aforementioned downlink signal may include one of the following:

[0110] Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), and the corresponding functions for RSRP, RSRQ, and SINR.

[0111] The terminal can select the resource group corresponding to the measurement result based on the mapping relationship between the measurement result and the resource group, thereby sending the first signal on the appropriate resource group to improve the transmission performance of the first signal. For example, the terminal can select the corresponding first resource group for WUS repetition by comparing the different SS-RSRP values ​​obtained from SSB signals associated with different resource group types with the SS-RSRP threshold.

[0112] The sequence information of the first signal mentioned above can represent the sequence identifier or sequence index of the first signal. The terminal can select the resource group corresponding to the sequence information based on the mapping relationship between the sequence information and the resource group, thereby transmitting the first signal on the appropriate resource group to improve the transmission performance of the first signal. For example, on a certain first resource, selecting WUS sequence X allows for... Figure 7 The repeated transmission of Case 2 shown, and the first resource selection WUS sequence Y, are then performed. Figure 7 The repeated transmission of Case 3 is shown.

[0113] The resource information for the first transmission of the first signal can be the time-frequency resource of the first transmission, such as WO, thereby selecting the first resource group in which the transmission resource is located.

[0114] The signal or channel triggered by the aforementioned first signal is either the aforementioned common downlink signal or common downlink channel, or the aforementioned common uplink signal or common uplink channel, or the aforementioned on-demand signal or on-demand channel. For example, the type of signal or channel triggered by the aforementioned first signal includes at least one of the following:

[0115] Synchronization signal, system information, control channel, PRACH, random access message, paging message, channel state information reference signal (CSI-RS), downlink wake-up signal, positioning reference signal (PRS), tracking reference signal (TRS), phase-tracking reference signal (PTRS), SRS, CGPUSCH, DL-WUS.

[0116] The aforementioned system information may include SIB1 and / or other system messages, and the aforementioned control channel may include control channel resource set, PDCCH and / or scheduling SIB1 or Random Access Response (RAR) or Msg4 or paging PDCCH.

[0117] In some implementations, the information of the signal or channel triggered by the first signal includes at least one of the following:

[0118] The type of signal or channel triggered by the first signal;

[0119] The purpose of the signal or channel triggered by the first signal;

[0120] The period of the signal or channel triggered by the first signal;

[0121] The bandwidth of the signal or channel triggered by the first signal;

[0122] The structure of the signal or channel triggered by the first signal;

[0123] The pattern of the signal or channel triggered by the first signal;

[0124] The number of times the signal or channel triggered by the first signal is repeated.

[0125] The above describes the uses of the signal or channel triggered by the first signal, which can be used for terminal cell search or for signal measurement.

[0126] The pattern of the signal or channel triggered by the first signal can represent a two-stage signal or channel triggered by the first signal, such as a two-stage SSB. For example, a two-stage SSB could be a public SSB where the first stage (stage-1) is a public SSB and the second stage (stage-2) is a feature-specific SSB. All types of terminals can receive the stage-1 SSB, but only some types of terminals can receive the stage-2 SSB. Another example is that a two-stage SSB can be an SSB in the low-power synchronization signal (LP-SS) + low-power wake-up signal scheme (SSB in LP-WUS case). Yet another example is that a two-stage SSB can be a wideband SSB + punctured narrowband SSB in the low-power wide area network (LPWA) scenario.

[0127] Based on the information of the signal or channel triggered by the first signal, the terminal can select a suitable first resource group, thereby improving the transmission performance of the first signal and the signal or channel triggered by the first signal. For example, when the signal triggered by the first signal is an SSB, high-reliability first signal transmission is required, and a suitable first resource group can be selected. Figure 7 The first resource group of type case 1 is shown; for example, when the signal triggered by the first signal is CSI-RS or SSB used for measurement, select... Figure 7 The first resource group of case2 shown can use either the first resource on the normal UL slot or the first resource on the SBFD.

[0128] The first downlink information received by the aforementioned terminal may include at least one of the following:

[0129] Radio Resource Control (RRC) information, Medium Access Control (MAC) information, Physical Downlink Control Channel (PDCCH) information, synchronization signals, system information, and paging messages.

[0130] The aforementioned RRC information can be RRC signaling used to configure the resource type for repeated transmission of the first signal. For example, the RRC signaling of Cell A can configure the resource type for triggering repeated transmission of the first signal of a specific reference signal (such as SSB) on Cell B.

[0131] The aforementioned synchronization signal can be SSB, and the aforementioned system information can be SIB1 or other system information.

[0132] The transmission resources for the first signal configured in the aforementioned first downlink information configuration can be configured as the type of transmission resource or the location of time-frequency resources, for example, paging can indicate the type of resource used to trigger the repeated transmission of the first signal of PRACH.

[0133] Since the aforementioned first downlink information is used to configure the transmission resources of the first signal, the first resource group corresponding to the transmission resource can be selected, making it easier for the network-side device to detect the first signal, thereby reducing the complexity of the network-side device in detecting the first signal.

[0134] It should be noted that when the first information includes multiple pieces of information, the terminal can select the appropriate first resource group based on the priority of these multiple pieces of information.

[0135] As an optional implementation, the first resource group may be of one of the following types:

[0136] The first resource in the first resource group is located only on the enhanced duplex resource;

[0137] The first resource in the first resource group is located only on non-enhanced duplex resources;

[0138] The first resource in the first resource group is located on the enhanced duplex resource and the non-enhanced duplex resource;

[0139] The enhanced duplex resources include at least one of the following:

[0140] Resources in the uplink subband within the uplink time unit, including the downlink subband;

[0141] Resources in the uplink subband within the downlink time unit;

[0142] Resources in the uplink subband within a flexible time unit;

[0143] The resources for non-enhanced duplexing include:

[0144] It only includes resources in the uplink time unit of the uplink subband.

[0145] The aforementioned flexible time unit refers to a time unit that can contain both uplink time domain resources and downlink time domain frequency domain resources, meaning that uplink and / or downlink transmission can be flexibly configured within this time unit.

[0146] The first resource in the first resource group mentioned above is located only on the enhanced duplex resource, which can be understood as all the first resources in the first resource group being resources on the enhanced duplex resource.

[0147] If the first resource in the first resource group is located only on the enhanced duplex resource, the enhanced duplex-enabled terminal can select the first resource group to send the first signal.

[0148] The first resource in the first resource group mentioned above is located only on non-enhanced duplex resources, which can be understood as all first resources in the first resource group being resources on non-enhanced duplex resources.

[0149] If the first resource in the first resource group is located only on a non-enhanced duplex resource, either enhanced duplex or non-enhanced duplex terminals can select the first resource group to send the first signal.

[0150] The first resource in the aforementioned first resource group, located on enhanced duplex resources and non-enhanced duplex resources, can be a first resource group that includes both first resources located on enhanced duplex resources and first resources located on non-enhanced duplex resources.

[0151] When the first resource in the aforementioned first resource group is located on an enhanced duplex resource and a non-enhanced duplex resource, an enhanced duplex-enabled terminal can transmit a first signal on the first resource located on an enhanced duplex resource in the first resource group, while a non-enhanced duplex-enabled terminal can transmit a first signal on the first resource located on a non-enhanced duplex resource in the first resource group.

[0152] The above three types enable different types of terminals to select the corresponding resource group to send the first signal, thus supporting different types of terminals to send the first signal.

[0153] As an optional implementation, if the first resource is applicable to both terminals that support enhanced duplex and terminals that do not support enhanced duplex, a portion of the first resource may be used only for terminals that do not support enhanced duplex.

[0154] The aforementioned first resource applies to both terminals that support enhanced duplex and terminals that do not support enhanced duplex. The first resource can include resources that can be used by terminals that support enhanced duplex and resources that can be used by terminals that do not support enhanced duplex. For example, a certain WO is used for WUS retransmission by terminals that support at least one enhanced duplex mode, and is also used for WUS retransmission by terminals that do not support enhanced duplex.

[0155] Among these, some of the resources in the first resource may be part of the time-frequency resources of the first resource or part of the first signal sequence resources, such as part of the WUS sequence resources. For example, a portion of the first resource may be reserved for repeated transmission of the first signal by terminals that do not support enhanced duplex.

[0156] Since some resources in the first resource are only used for terminals that do not support enhanced duplex, both terminals that support enhanced duplex and terminals that do not support enhanced duplex can choose the first resource to send the aforementioned first signal, thereby improving the transmission efficiency of the communication system.

[0157] As an optional implementation, the terminal determines the first resource group by:

[0158] The terminal determines the first resource group based on the second information;

[0159] Where the terminal does not support enhanced duplex, the second information indicates at least one of the following:

[0160] The first resource located on the enhanced duplex resource is an invalid or unavailable resource;

[0161] The second resource group is an invalid resource group or an unavailable resource group, where the Xth first resource in the second resource group is on the enhanced duplex resource, or, at least X first resources in the second resource group are on the enhanced duplex resource, where X is a positive integer;

[0162] The first resource located on the enhanced duplex resource and the first resource located on the non-enhanced duplex resource within the first resource group use different sequences;

[0163] The first resource is determined only on the non-enhanced duplex resource;

[0164] And / or,

[0165] If the terminal at least supports enhanced duplex, the second information indicates one of the following:

[0166] The first resource is determined only on the enhanced duplex resource; or,

[0167] The first resource is determined on both the enhanced duplex resource and the non-enhanced duplex resource.

[0168] If the first resource located on the enhanced duplex resource is an invalid or unavailable resource, then if the first resource group includes the first resource located on the enhanced duplex resource, then the terminal that does not support enhanced duplex determines that the first resource is an invalid or unavailable resource.

[0169] The second resource group mentioned above being an invalid or unavailable resource group can be caused by the terminal not selecting the second resource group as the first resource group when determining the first resource group.

[0170] The above X can be a positive integer as defined by the protocol or configured by the network-side device.

[0171] The use of different sequences for the first resource located on the enhanced duplex resource and the first resource located on the non-enhanced duplex resource within the first resource group can be achieved by using different first signal sequences for the first resource located on the enhanced duplex resource and the first resource located on the non-enhanced duplex resource within the first resource group. This facilitates the network-side device to flexibly configure the first signal sequence for different terminal types on the two types of first resources.

[0172] If the terminal does not support enhanced duplex, the second information mentioned above can be used to determine a suitable first resource group, so as to avoid the terminal determining an unsuitable first resource.

[0173] In some implementations, if the terminal does not support enhanced duplex, the terminal may determine the first resource group only by configuring resources on non-enhanced duplex uplink resources, ignoring resources on enhanced duplex uplink resources.

[0174] The above-mentioned terminals at least support enhanced duplex, which can be understood as the terminals supporting enhanced duplex, and also supporting or not supporting non-enhanced duplex.

[0175] The above only determines the first resource on the enhanced duplex resource, which can be at least a resource group that supports enhanced duplex on the terminal when determining the first resource group, only selecting the enhanced duplex resource.

[0176] The above-mentioned determination of the first resource on the enhanced duplex resources and the non-enhanced duplex resources can be at least supported by the terminal that, when determining the first resource group, can select either the first resource on the enhanced duplex resources or the first resource on the non-enhanced duplex resources.

[0177] With the terminal supporting at least enhanced duplex, the appropriate first resource group can be determined using the aforementioned second information.

[0178] It should be noted that the aforementioned terminal can determine the first resource group based on the second information and the first information. For example, it can first determine candidate resource groups based on the second information, and then determine the first resource group from the candidate resource groups based on the first information; or it can first determine candidate resource groups based on the first information, and then determine the first resource group from the candidate resource groups based on the second information. This method of determining the first resource group based on the second information and the first information makes the first resource group more reliable.

[0179] As an optional implementation, the method further includes:

[0180] The terminal determines the sequence of the first signal based on the third information;

[0181] The third information includes at least one of the following:

[0182] The total number of sequences of the first sequence type on at least one of the first resources;

[0183] An identifier of the starting sequence of a first sequence type on at least one of the first resources;

[0184] The number of sequences associated with at least one synchronization signal for triggering at least one signal or channel in at least one first sequence type on at least one first resource;

[0185] The number of sequences in a first sequence type on at least one of the first resources used to trigger at least one signal or channel;

[0186] The total number of sequences of the second sequence type on at least one of the first resources;

[0187] An identifier of the starting sequence of the second sequence type on at least one of the first resources;

[0188] The number of sequences associated with at least one synchronization signal for triggering at least one signal or channel in at least one second sequence type on at least one first resource;

[0189] The number of sequences in a second sequence type used to trigger at least one signal or channel on at least one of the first resources;

[0190] The interval between the sequence set of the first sequence type and the sequence set of the second sequence type;

[0191] Sequence information associated with at least one synchronization signal or at least a set of synchronization signals;

[0192] Wherein, the first sequence type is a sequence type used by a terminal that supports at least one enhanced duplex mode, and the second sequence type is a sequence type used by a terminal that does not support enhanced duplex.

[0193] The aforementioned third piece of information may be network-side device configuration or protocol agreement.

[0194] The aforementioned synchronization signal can be SSB, CSI-RS, or PRACH.

[0195] The sequence associated with the above-mentioned at least one synchronization signal for triggering at least one signal or channel can be a sequence mapped to each synchronization signal for triggering at least one signal or channel.

[0196] The total number of sequences of the first sequence type on at least one of the first resources can be the total number of sequences of the first sequence type on each of the first resources.

[0197] The identifier of the starting sequence of the first sequence type on at least one of the first resources can be the identifier of the starting sequence of the first sequence type on each of the first resources.

[0198] In the first sequence type on at least one first resource, the number of sequences associated with at least one synchronization signal for triggering at least one signal or channel can be the number of sequences mapped to each synchronization signal on each first resource for triggering at least one signal or channel, such as the number of WUS sequences mapped to each SSB for triggering one or more signals in the first sequence type on each WO.

[0199] The number of sequences used to trigger at least one signal or channel in at least one first sequence type on at least one first resource can be the number of sequences used to trigger each signal or channel in each first sequence type on each first resource, such as configuring the number of sequences used to trigger SSB and the number of sequences used to wake up PRACH.

[0200] Alternatively, the number of sequences used to trigger at least one signal or channel in at least one first sequence type on the first resource may be the total number of sequences in at least one first sequence type on the first resource minus the number of sequences used for other purposes (such as triggering discontinuous transmission (DTX) or discontinuous reception (DRX)).

[0201] The total number of sequences of the second sequence type on at least one of the first resources can be the total number of sequences of the second sequence type on each of the first resources.

[0202] The identifier of the starting sequence of the second sequence type on at least one of the first resources can be the identifier of the starting sequence of the second sequence type on each of the first resources.

[0203] In the second sequence type on at least one first resource, the number of sequences associated with at least one synchronization signal for triggering at least one signal or channel can be the number of sequences mapped to each synchronization signal on each first resource for triggering at least one signal or channel, such as the number of WUS sequences mapped to each SSB for triggering one or more signals in the second sequence type on each WO.

[0204] The number of sequences used to trigger at least one signal or channel in at least one of the second sequence types on the first resource can be the number of sequences used to trigger each signal or channel in each of the second sequence types on the first resource, such as configuring the number of sequences used to trigger SSB and the number of sequences used to wake up PRACH.

[0205] Alternatively, the number of sequences used to trigger at least one signal or channel in at least one second sequence type on the first resource may be the total number of sequences of at least one second sequence type on the first resource minus the number of sequences used for other purposes (such as triggering DTX or DRX).

[0206] The interval between the sequence set of the first sequence type and the sequence set of the second sequence type can be that the sequence set of the second sequence type is formed by reserving N sequences after the last sequence of the sequence set of the first sequence type. For example, the first sequence of the second sequence type has an offset relative to the last sequence of the first sequence type.

[0207] For example: Each WO contains a total of 64 WUS sequences. The first sequence type has a total of 28 sequences, mapped to 4 SSBs. Each SSB is mapped to 5 WUS sequences to trigger SIB1, and each SSB is mapped to 2 WUS sequences to trigger PRACH. The second sequence type also has a total of 28 sequences, mapped to 4 SSBs. Each SSB is mapped to 5 WUS sequences to trigger SIB1, and each SSB is mapped to 2 WUS sequences to trigger PRACH.

[0208] like Figure 8 As shown, Figure 8 In the WUS Type1, it indicates the first sequence type; WUS Type2 indicates the second sequence type; and Offset indicates the offset. Figure 8 As shown, the sequence set of the first sequence type is separated from the sequence set of the second sequence type by 8 WUS sequences (i.e., offset).

[0209] For example: There are a total of 64 WUS sequences on each WO. The total number of sequences in the first sequence type is 32. The total number of WUS sequences used to activate SIB1 / PRACH in the first sequence type is 28, which are mapped to 4 SSBs. Each SSB is mapped to 5 WUS sequences to trigger SIB1, and each SSB is mapped to 2 WUS sequences to trigger PRACH.

[0210] The second sequence type has a total of 32 sequences. The second sequence type has a total of 28 WUS sequences used to activate SIB1 / PRACH, and these are also mapped to 4 SSBs. Each SSB is mapped to 5 WUS sequences to trigger SIB1, and each SSB is mapped to 2 WUS sequences to activate PRACH.

[0211] like Figure 9 As shown, Figure 9 In the WUS Type 1 code, WUS Type 2 code indicates the first sequence type, WUS Type 2 code indicates the second sequence type, and Other indicates other uses, such as... Figure 9 As shown, both the first sequence type and the second sequence type sequence have reserved WUS sequences for other purposes. For example, both the first sequence type and the second sequence type sequence have reserved 4 WUS sequences for other purposes.

[0212] The sequence information associated with at least one synchronization signal or at least one group of synchronization signals can be configured at the granularity of synchronization signal or group of synchronization signals.

[0213] The aforementioned third information enables the terminal to select an appropriate sequence to send the first signal, thereby allowing the network-side device to detect the first signal more effectively and improving the reliability of the first signal transmission.

[0214] In some implementations, the sequence information associated with at least one synchronization signal or at least a set of synchronization signals includes at least one of the following:

[0215] The total number of sequences of at least one first sequence type on the first resource associated with at least one synchronization signal or at least a set of synchronization signals;

[0216] An identifier of a start sequence of a first sequence type on the first resource, associated with at least one synchronization signal or at least a set of synchronization signals;

[0217] The number of sequences in at least one first sequence type on the first resource used to trigger at least one signal or channel, associated with at least one synchronization signal or at least one set of synchronization signals;

[0218] An identifier of a start sequence in at least one first sequence type on the first resource, associated with at least one synchronization signal or at least one set of synchronization signals, for triggering at least one signal or channel;

[0219] The total number of sequences of at least one second sequence type on the first resource associated with at least one synchronization signal or at least a set of synchronization signals;

[0220] The identifier of at least one start sequence of a second sequence type on the first resource, associated with at least one synchronization signal or at least a set of synchronization signals;

[0221] The number of sequences in at least one second sequence type on the first resource used to trigger at least one signal or channel, associated with at least one synchronization signal or at least one set of synchronization signals;

[0222] An identifier of a start sequence in at least one second sequence type on the first resource, associated with at least one synchronization signal or at least one set of synchronization signals, for triggering at least one signal or channel;

[0223] The interval between a set of sequences of a first sequence type and a set of sequences of a second sequence type, which are associated with at least one synchronization signal or at least a group of synchronization signals;

[0224] The total number of sequences associated with at least one synchronization signal or at least a set of synchronization signals for triggering at least one signal or channel;

[0225] The number of sequences in a first sequence type on at least one first resource for triggering at least one signal or channel, associated with at least one synchronization signal or at least a set of synchronization signals;

[0226] The number of sequences in a second sequence type on at least one first resource that are associated with at least one synchronization signal or at least a set of synchronization signals for triggering at least one signal or channel;

[0227] The total number of sequences of other uses in at least one first sequence type on the first resource, associated with at least one synchronization signal or at least one set of synchronization signals;

[0228] The total number of sequences of other uses in at least one second sequence type on the first resource, associated with at least one synchronization signal or at least one set of synchronization signals;

[0229] The identifier of the starting sequence of at least one sequence of a first sequence type on the first resource for other purposes, associated with at least one synchronization signal or at least a set of synchronization signals;

[0230] The identifier of the starting sequence of at least one sequence of a second sequence type on the first resource for other purposes, associated with at least one synchronization signal or at least a set of synchronization signals;

[0231] The total number of sequences of signals or channels in at least one first sequence type on the first resource that are associated with at least one synchronization signal or at least one set of synchronization signals and used to trigger the connected state;

[0232] The total number of sequences of at least one second sequence type on the first resource used to trigger the connected state, associated with at least one synchronization signal or at least one set of synchronization signals;

[0233] The other uses refer to uses other than those used for triggering signals or channels.

[0234] The other uses mentioned above may be for purposes other than triggering signals or channels, such as triggering DTX or DRX transmissions.

[0235] In the above embodiments, sequence information can be configured at the granularity of synchronization signals or groups of synchronization signals, for example: Figure 10 As shown, Figure 10 In this context, Type1 indicates the first sequence type, Type2 indicates the second sequence type, and Other indicates other uses, such as... Figure 10 As shown, each WO contains a total of 64 WUS sequences. 48 of these are used for activation of signals in both the non-connected and connected states, and are mapped to 2 SSBs. Each SSB maps to 10 WUS sequences of type 1 and 10 WUS sequences of type 2 for activation of signals in the non-connected state. Alternatively, each SSB maps to 2 WUS sequences of type 1 and 2 WUS sequences of type 2 for activation of signals in the connected state. A total of 16 WUS sequences are used for other purposes (such as triggering DTX / DRX), also mapped to 2 SSBs. Each SSB maps to 4 WUS sequences of type 1 and 4 WUS sequences of type 2.

[0236] By configuring sequence information at the granularity of synchronization signals or synchronization signal groups, the terminal can more accurately determine the appropriate sequence to send the first signal, thereby improving the transmission reliability of the first signal.

[0237] In some implementations, the sequence of the first signal may also be agreed upon by a protocol or configured by the network-side device.

[0238] As an optional implementation, the first resource group is determined based on at least one of the following:

[0239] The first mapping period from the downlink signal to the first resource, wherein the first resource includes at least two types within the first mapping period;

[0240] The downlink signal is mapped to the first resource in a second mapping period, during which the first resource contains only one type;

[0241] The downlink signal to the first resource is mapped in a third mapping period, wherein the mapping order or method of the downlink signal to the first resource is different in at least two periods of the third mapping period.

[0242] The aforementioned downlink signal includes at least one of the following:

[0243] SSB, CSI-RS, Paging, paging PDCCH, paging PDSCH, PRS, or other signals used for downlink measurements and associated with WUS transmission or signals triggered by WUS.

[0244] The first, second, and third mapping periods mentioned above are mapping periods from downlink signals to the first resource, meaning that the first resource within these mapping periods has associated downlink signals.

[0245] In some implementations, the first mapping period, the second mapping period, and the third mapping period may also be referred to as the mapping mode period, the downlink signal to the first resource mapping period, the downlink signal to the first resource association period, or the enhanced duplex configuration period.

[0246] The aforementioned first resource group can be determined based on at least one of the first mapping period, the second mapping period, and the third mapping period. For example, in any one of the first mapping period, the first period (i.e., N1 second mapping periods), and the second period (i.e., N2 third mapping periods), all downlink signals are mapped to the first resource group at least once, such as completing a round of mapping of all downlink signals to the first resource group within N1 second mapping periods or N2 third mapping periods.

[0247] It should be noted that at least one of the above-mentioned first mapping period, second mapping period, and third mapping period can be used separately from or in combination with the above-mentioned first information and second information. For example, candidate resource groups can be determined first in at least one of the above-mentioned first mapping period, second mapping period, and third mapping period, and then the first resource group can be determined from the candidate resource groups based on the first information and / or the second information; or, candidate resource groups can be determined first based on the first information and / or the second information, and then the resource groups belonging to at least one of the above-mentioned first mapping period, second mapping period, and third mapping period can be determined from the candidate resource groups as the first resource group.

[0248] The aforementioned first mapping period includes one or more periods, and the aforementioned first resource includes at least two types, which may include the following two types:

[0249] Resources that are not enhanced duplex;

[0250] Resources to enhance duplex functionality.

[0251] Since the first resource in the first mapping period includes at least two types, this allows terminals of various types to select the appropriate first resource in the first mapping period.

[0252] The second mapping period mentioned above includes one or more periods, and the first resource mentioned above contains only one type, which can be a non-enhanced duplex resource or an enhanced duplex resource.

[0253] In the second mapping period, the first resource contains only one type, which allows specific types of terminals to select the first resource in the second mapping period.

[0254] The mapping order or method of downlink signals to the first resource is different in at least two cycles of the third mapping cycle, which can support more flexible mapping of downlink signals to the first resource, so as to support more flexible transmission.

[0255] In some implementations, the first mapping period satisfies at least one of the following:

[0256] During at least one of the first mapping periods, each downlink signal can be associated with at least one first resource group, which contains only non-enhanced duplex resources;

[0257] During at least one of the first mapping periods, each downlink signal can be associated with at least one first resource group, which contains only enhanced duplex resources;

[0258] During at least one of the first mapping periods, each downlink signal can be associated with at least one first resource group, which includes enhanced duplex resources and non-enhanced duplex resources.

[0259] Each of the above downlink signals refers to a different index of the same downlink signal, such as SSB index 1 to SSB index 8. Each of the eight SSBs is associated with a first resource group.

[0260] The aforementioned first resource group, which only contains non-enhanced duplex resources, can be understood as a first resource group that does not support the repeated transmission of the first signal of a terminal that does not support enhanced duplex, i.e., a first resource group that does not support the repeated transmission of the first signal of a terminal that does not support enhanced duplex.

[0261] The aforementioned first resource group containing only enhanced duplex resources can be understood as the first resource group that supports the repeated transmission of the first signal of the enhanced duplex terminal, that is, the first resource group that supports the repeated transmission of the first signal of the enhanced duplex terminal.

[0262] The aforementioned first resource group, which includes enhanced duplex resources and non-enhanced duplex resources, can be understood as a first resource group for repeated transmission of the first signal of a terminal supporting enhanced duplex and a terminal supporting enhanced duplex, that is, a first resource group for repeated transmission of the first signal of a terminal supporting enhanced duplex and a terminal not supporting enhanced duplex.

[0263] In this implementation, both enhanced duplex resources and non-enhanced duplex resources can be mapped to the first resource by the downlink signal, thereby improving the reliability of the terminal transmitting the first signal on these resources.

[0264] In some implementations, the second mapping period satisfies at least one of the following:

[0265] In at least one first cycle, each downlink signal can be associated with at least one first resource group, which contains only enhanced duplex resources;

[0266] In at least one first cycle, each downlink signal can be associated with at least one first resource group, which contains only non-enhanced duplex resources;

[0267] The first period includes N1 second mapping periods, where N1 is an integer greater than or equal to 1.

[0268] The aforementioned N1 second mapping cycles can also be understood as N1 times the second mapping cycle, and the aforementioned at least one first cycle can also be understood as at least N1 times the second mapping cycle.

[0269] In this context, N1 being an integer greater than or equal to 1 can be understood as follows: In one scheme, N1 is an integer greater than 1, i.e., multiple second mapping cycles. In this scheme, it takes multiple second mapping cycles to complete the mapping of all downlink reference signal indices (e.g., SSBindex1 to index8) to the first resource group. In another scheme, N1 can be either greater than 1 or equal to 1, i.e., at least one second mapping cycle.

[0270] In this implementation, both enhanced duplex resources and non-enhanced duplex resources can be mapped to the first resource by the downlink signal, thereby improving the reliability of the terminal transmitting the first signal on these resources.

[0271] In some implementations, the third mapping period satisfies at least one of the following:

[0272] During at least one second cycle, each downlink signal can be associated with at least one first resource group, which contains only resources for enhanced duplex;

[0273] During at least one second cycle, each downlink signal can be associated with at least one first resource group, which contains only non-enhanced duplex resources;

[0274] During at least one second cycle, each downlink signal can be associated with at least one first resource group, which includes enhanced duplex resources and non-enhanced duplex resources;

[0275] The second period includes N2 of the third mapping periods, where N2 is an integer greater than or equal to 1.

[0276] The aforementioned N2 third mapping cycles can also be understood as N2 times the third mapping cycle, and the aforementioned at least one second cycle can also be understood as at least N2 times the third mapping cycle.

[0277] In this context, N2 being an integer greater than or equal to 1 can be understood as follows: In one scheme, N2 is an integer greater than 1, meaning multiple third mapping cycles. In this scheme, it takes multiple third mapping cycles to complete the mapping of all downlink reference signal indices (e.g., SSB index1 to index8) to the first resource group. In another scheme, N2 can be either greater than 1 or equal to 1, meaning at least one third mapping cycle.

[0278] In this implementation, both enhanced duplex resources and non-enhanced duplex resources can be mapped to the first resource by the downlink signal, thereby improving the reliability of the terminal transmitting the first signal on these resources.

[0279] As an optional implementation, the method further includes:

[0280] The terminal receives second downlink information, which is used to configure the time window of the first resource group.

[0281] The aforementioned time window can be understood as an explicit configuration, such as ensuring that all downlink signals are mapped to the first resource group at least once within the configured time window.

[0282] Wherein, the time window of the first resource group mentioned above can be such that the first resource in the first resource group used for the first signal transmission can only be located in the time window, and the time window can include at least one of the start position, end position and length of the time window.

[0283] The aforementioned second downlink information may include at least one of the following:

[0284] RRC information, MAC information, PDCCH, synchronization signals, system information, paging messages.

[0285] For example, the RRC information mentioned above can be RRC signaling used to configure the resource type for repeated transmission of the first signal. For example, the RRC signaling of Cell A can configure the resource type for triggering repeated transmission of the first signal of a specific reference signal (such as SSB) on Cell B.

[0286] For example, the synchronization signal mentioned above can be configured with a time window for determining the resource retransmission of the first signal. For instance, the PBCH payload can be configured with this time window. In the case of a two-level SSB, the first-level SSB is configured with a time window for determining the resource retransmission of the first signal to trigger the second-level SSB.

[0287] For example, the paging message described above can indicate the time window for determining the recurring transmission resources used to trigger the first signal of PRACH.

[0288] In this implementation, since the time window is configured through the second downlink information, the time window of the first resource group can be dynamically configured to support more flexible transmission.

[0289] In some implementations, the aforementioned time window may also be agreed upon in the protocol.

[0290] In some implementations, the second downlink information is configured with a time window for the first resource group based on at least one of the following granularities:

[0291] First resource type, terminal, TRP, synchronization signal, synchronization signal group, carrier, BWP, frequency range, bandwidth and bandwidth combination.

[0292] The time window for configuring the first resource group at the above granularity can be configured independently for each granularity of the first resource group. For example, the corresponding time window can be configured independently for different first resource types, such as for different terminals, for different TRPs, for different synchronization signals, etc. These will not be elaborated on here.

[0293] In this embodiment, since the time window of the first resource group is configured with the above-mentioned granularity, the time window of the first resource group can be made more accurate.

[0294] In this embodiment, the terminal determines a first resource group, which includes at least one first resource, which is a transmission resource for a first signal or a repetitive transmission resource. The terminal sends a first signal in the first resource group, which is used for at least one of the following: triggering the transmission of a common downlink signal or a common downlink channel; triggering the transmission of a common uplink signal or a common uplink channel; or triggering the transmission of an on-demand signal or an on-demand channel. This enables the terminal to send a first signal in the first resource group to trigger the transmission of the corresponding signal or channel, thereby improving the terminal's communication performance.

[0295] Please see Figure 11 , Figure 11 This is a flowchart of another signal transmission method provided in an embodiment of this application, such as... Figure 11 As shown, it includes the following steps:

[0296] Step 1101: The network-side device receives a first signal in a first resource group, the first resource group including at least one first resource, the first resource being a transmission resource or a retransmission resource of the first signal;

[0297] The first signal is used for at least one of the following:

[0298] Triggering the transmission of a common downlink signal or a common downlink channel;

[0391] Optionally, the second downlink information is configured with the time window of the first resource group based on at least one of the following granularities:

[0392] First resource type, terminal, Transmit / Receive Point (TRP), synchronization signal, synchronization signal group, carrier, bandwidth portion (BWP), frequency range, bandwidth, and bandwidth combination.

[0393] It should be noted that this embodiment is as a comparison with... Figure 6 The implementation methods of the network-side devices shown in the embodiments can be found in the following examples. Figure 6 To avoid repetition, the relevant descriptions of the embodiments shown will not be repeated in this embodiment.

[0394] The following example, using WUS as the first signal, illustrates the method provided in this application:

[0395] In one embodiment provided in this application, the determination of WUS resource groups (i.e., the first resource group mentioned above) for terminals with different duplex capabilities is mainly described.

[0396] In order to support at least one enhanced duplex mode terminal in idle / inactive state, and to also consider WUS retransmission for terminals that do not support enhanced duplex, multiple sets of WUS retransmission resources need to be considered.

[0397] In the embodiments of this application, the enhanced duplex, enhanced duplex mode, XDD, enhanced full duplex, and enhanced full duplex mode can represent a concept, which can be expressed as supporting uplink subband in the downlink time unit and / or supporting downlink subband in the uplink time unit and or supporting both uplink and downlink subband transmission in the flexible time unit.

[0398] In some implementations, multiple types of WO groups can be supported, such as Figure 7 As shown, there are three cases: Case 1, where the WO is only on the UL time unit (e.g., a time slot); Case 2, where the WO is only on the UL subband (e.g., the uplink subband within a downlink time unit); and Case 3, where the WO group appears in both types of WOs (i.e., the WO can be on the UL time slot or the UL subband). In this case, for different types of WO groups appearing on the same WO, some WUS sequence resources need to be reserved for different cases.

[0399] In this embodiment of the application, WO refers to the time-frequency resources required to send a WUS.

[0400] In some implementations, for the existence of multiple types of WO groups, the WO group type can be selected based on one or more of the following factors:

[0401] The terminal's full-duplex capability; for example, for terminals supporting enhanced full-duplex capability, Case 1, Case 2, or Case 3 can be used. The specific WO group type depends on which cases are configured in the network.

[0402] Measurement metrics associated with downlink signals of different WO group types (such as RSRP / RSRQ / SINR, or functions thereof); for example, the terminal selects the corresponding WO group for WUS repetition by comparing different SS-RSRP values ​​measured by SSB signals associated with different WO group types with the SS-RSRP threshold.

[0403] The terminal selects the WUS sequence on WO; for example, in WO1, selecting WUS sequence X will repeat Case 2; selecting WUS sequence Y will repeat Case 3 (in red);

[0404] The first WO is transmitted, and a certain WO corresponds to a specific WO group / repeated transmission.

[0405] The type or purpose of the signal or channel triggered by WUS; for example, when the signal triggered by WUS is SSB, select case 1 type WO, which requires high-reliability WUS transmission; or when the signal triggered by WUS is CSI-RS or SSB used for measurement, select case 2 type WO, which can use either the WO on the normal UL slot or the WO on the SBFD.

[0406] In some implementations, for the existence of multiple types of WO groups, the WO group type can also be selected through network-side device configuration, which may include one or more of the following methods:

[0407] RRC / MAC / PDCCH configuration, for example, the RRC signaling of Cell A can be configured to trigger the WUS retransmission resource type for specific reference signals (such as SSB) on Cell B;

[0408] SSB, such as PBCH payload, can be configured with resource types for triggering WUS retransmission of SIB1; for example, in the case of supporting two-level SSB, the first-level SSB is configured with resource types for triggering WUS retransmission of the second-level SSB; it should be noted that in the embodiments of this application, SSB, SS and PBCH block can be used interchangeably or with other names to represent any module containing at least some synchronization signals, broadcast signals or other downlink broadcast signals or their scheduling channels;

[0409] SIB1 or other system information;

[0410] Paging; for example, paging can indicate the type of resource used to trigger repeated transmissions of the WUS signal for PRACH.

[0411] By using the conditions and methods described above, the complexity of WUS detection by network-side devices can be reduced to some extent.

[0412] As a sub-implementation of the previous embodiment, the type or purpose of the signal triggered by WUS includes at least one of the following:

[0413] signal period

[0414] signal bandwidth

[0415] Signal structure

[0416] Is the signal a first-level signal or a second-level signal?

[0417] For example, Level 1 SSB and Level 2 SSB

[0418] Is the signal used for terminal cell search or for signal measurement?

[0419] Number of signal retransmissions

[0420] The signal can be one or more of the following types:

[0421] SSB;

[0422] SIB1 or other system messages;

[0423] Control channel resource set or PDCCH, such as scheduling SIB1 or RAR or Msg4 or paging PDCCH;

[0424] PRACH;

[0425] MsgA;

[0426] Paging;

[0427] CSI-RS;

[0428] PRS;

[0429] DL WUS;

[0430] TRS;

[0431] PTRS.

[0432] In some implementations, when a certain WO is used for WUS retransmission by both terminals that support at least one enhanced duplex mode and terminals that do not support enhanced duplex, a portion of WUS resources are reserved for WUS retransmission by terminals that do not support enhanced duplex. Here, the WUS resources can be WUS sequences.

[0433] In this embodiment of the application, the WUS resource may be a WUS time-frequency resource (such as WO) and / or a WUS sequence resource.

[0434] In the embodiments of this application, the WUS resources determined by the terminal may include shared WOs, which are WUS resources used for both one type of WUS transmission and another type of WUS transmission. Alternatively, the WUS resources determined by the terminal may be separate WOs or separately configured WOs, which are WUS resources additionally configured solely for a specific type of WUS transmission.

[0435] As a sub-implementation of the previous embodiment, for terminals that support at least one enhanced duplex mode and terminals that do not support enhanced duplex, the respective WO groups used for WUS repetitive transmissions are determined in one or more of the following ways:

[0436] Method 1: Determine the WOgroup together for the WO resources configured on both enhanced duplex and non-enhanced duplex uplink resources;

[0437] Optionally, for terminals that only support non-enhanced duplex, if a WO appears in a WO group on an uplink resource in enhanced duplex, the terminal considers the WO invalid or that the WO is not used for WUS retransmission.

[0438] Optionally, for terminals that only support non-enhanced duplex, if the Xth WO appearing in a WO group is on an enhanced duplex uplink resource, the terminal considers the WO group invalid or that the WO group is not used for WUS retransmission. For example, here X = 1.

[0439] Optionally, for terminals that only support non-enhanced duplex, if at least X WOs appear in a WO group on enhanced duplex uplink resources, the terminal considers the WO group invalid or that the WO group is not used for PRACH retransmission. For example, X = N / 2, where N is the number of retransmissions.

[0440] Optionally, for terminals that support non-enhanced duplex, the WOs on enhanced duplex uplink resources and the WOs on non-enhanced duplex uplink resources within the WO group can use different WUS sequences for repeated WUS transmission.

[0441] This situation allows network-side devices to flexibly configure WUS sequences for different terminal types on both WOs.

[0442] Method 2: For terminals that do not support enhanced duplex, the WO resources configured on the non-enhanced duplex uplink resources are determined independently to form a WO group. That is, for terminals that do not support non-enhanced duplex, the terminals ignore the WOs on the enhanced duplex uplink resources.

[0443] The aforementioned enhanced duplex uplink resources can refer to resources that support uplink subband transmission within the downlink time unit and / or support downlink subband transmission within the uplink time unit and / or support both uplink and downlink subband transmission within the flexible time unit. The non-enhanced duplex uplink resource configuration refers to other time-frequency resources used for WUS transmission.

[0444] As another sub-implementation of the previous embodiment, for terminals that support at least one enhanced duplex mode and terminals that do not support enhanced duplex, the respective WUS sequences for WUS repetitive transmission are determined by one or more of the following methods:

[0445] Method 1: Define a first type of WUS sequence (i.e., the first sequence type in the above embodiments) for terminals that do not support enhanced duplex; define a second type of WUS sequence (i.e., the second sequence type in the above embodiments) for terminals that support at least one enhanced duplex mode. Alternatively, the definitions of the first and second types of WUS sequences can be interchanged.

[0446] Method 2: The network-side device must be configured with at least one or more of the following information:

[0447] Configure the total number of first-class WUS sequences on WO;

[0448] Configure the number of WUS sequences in the first type of WUS sequence on the WO that are mapped to each SSB for activating / triggering one or more signals;

[0449] Configure the total number of second-type WUS sequences on WO;

[0450] Configure the starting WUS sequence ID for the second type of WUS sequence on WO;

[0451] Configure the number of WUS sequences in the second type of WUS sequences on the WO that are mapped to each SSB for activating / triggering one or more signals. For example, configure the number of WUS sequences used to activate the SSB, such as the number of WUS sequences used to activate PRACH.

[0452] Configure the interval between the first type of WUS sequence set and the second type of WUS sequence set. For example, after the last WUS sequence of the first type of WUS sequence, reserve N WUS sequences before the WUS sequence of the second type of WUS sequence. That is, the first second type of WUS sequence has an offset relative to the last first type of WUS sequence.

[0453] Configure the total number of WUS sequences in the first category on the WO for activating / triggering one or more signals. Then, the number of WUS sequences in the first category used for other purposes (such as triggering DTX / DRX) is the total number of WUS sequences in the first category minus the total number of WUS sequences in the first category used for activating / triggering one or more signals.

[0454] Configure the total number of WUS sequences of the second type used to activate / trigger one or more signals on the WO. In this way, the number of WUS sequences of the second type used for other purposes (such as triggering DTX / DRX) is the total number of WUS sequences of the second type minus the total number of WUS sequences of the second type used to activate / trigger one or more signals.

[0455] For example: Figure 8 As shown, Figure 8 In this context, WUS Type1 represents the first type of WUS sequence, WUS Type2 represents the second type of WUS sequence, and Offset represents the offset, such as... Figure 8As shown, each WO contains a total of 64 WUS sequences. The first type has 28 WUS sequences, mapped to 4 SSBs. Each SSB is mapped to 5 WUS sequences to trigger SIB1, and each SSB is mapped to 2 WUS sequences to trigger PRACH. The second type also has 28 WUS sequences, mapped to 4 SSBs. Each SSB is mapped to 5 WUS sequences to trigger SIB1, and each SSB is mapped to 2 WUS sequences to trigger PRACH. There is an 8-WUS sequence offset between the two types of WUS sequences.

[0456] For example, such as Figure 9 As shown, Figure 9 In the WUS Type 1, it represents the first type of WUS sequence; WUS Type 2 represents the second type of WUS sequence; Other indicates other uses, such as... Figure 9 As shown, each WO contains a total of 64 WUS sequences. The first type has 32 WUS sequences in total, with 28 of them used to activate SIB1 / PRACH. These are mapped to 4 SSBs, each SSB mapping to 5 WUS sequences to trigger SIB1, and each SSB mapping to 2 WUS sequences to trigger PRACH. The second type also has 32 WUS sequences in total, with 28 used to activate SIB1 / PRACH. These are also mapped to 4 SSBs, each SSB mapping to 5 WUS sequences to trigger SIB1, and each SSB mapping to 2 WUS sequences to activate PRACH. Each type of WUS sequence has 4 reserved WUS sequences for other uses.

[0457] Method 2: The network is configured with at least one or more of the following information under each or each SSB group:

[0458] Configure the total number of WUS sequences on WO;

[0459] Configure the number of WUS sequences in the first type of WUS sequences on the WO for activating one or more signals;

[0460] Configure the starting WUS sequence ID in the second type of WUS sequence on the WO to activate one or more signals;

[0461] Configure the number of WUS sequences in the second type of WUS sequences on the WO for activating one or more signals;

[0462] Configure the interval between the first type of WUS sequence set and the second type of WUS sequence set. For example, the WUS sequence after the last WUS sequence of the first type of WUS sequence mapped to a SSB, after an interval of N WUS sequences, is the second type of WUS sequence mapped to that SSB. That is, the first second type of WUS sequence mapped to the same SSB has an offset relative to the last first type of WUS sequence mapped to that SSB;

[0463] Configure the total number of WUS sequences on the WO used to activate one or more signals. Thus, the number of WUS sequences used for other purposes (such as triggering DTX / DRX) is the total number of WUS sequences minus the total number of WUS sequences used to activate one or more signals.

[0464] Configure the total number of WUS sequences of the first type on WO for other purposes (such as triggering DTX / DRX);

[0465] Configure the total number of second-class WUS sequences on WO for other purposes (such as triggering DTX / DRX);

[0466] Configure the second type of WUS sequence on WO for use as the starting sequence ID for other purposes (such as triggering DTX / DRX);

[0467] Configure the number of WUS sequences in the first type of WUS sequences on the WO for signal activation when the terminal is in the connected state;

[0468] Configure the number of WUS sequences in the second type of WUS sequences on the WO for signal activation when the terminal is in the connected state;

[0469] For example, such as Figure 10 As shown, Figure 10 In this context, Type1 represents the first type of WUS sequence, Type2 represents the second type of WUS sequence, and Other represents other uses, such as... Figure 10 As shown, each WO contains a total of 64 WUS sequences. 48 WUS sequences are used for activation of signals in both disconnected and connected states, mapped to 2 SSBs. Each SSB maps to 10 Type I WUS sequences and 10 Type II WUS sequences for activation of signals in disconnected states. Each SSB maps to 2 Type I WUS sequences and 2 Type II WUS sequences for activation of signals in connected states. A total of 16 WUS sequences are used for other purposes (such as triggering DTX / DRX), also mapped to 2 SSBs. Each SSB maps to 4 Type I and 4 Type II WUS sequences.

[0470] It should be noted that, in the embodiments of this application, the SSB to WO mapping can also refer to the association between downlink signals and uplink signals or resources in a broad sense, such as the relationship between CSI-RS and WO.

[0471] Another embodiment provided in this application mainly describes the window design used for WO group determination.

[0472] In enhanced duplex configurations, multiple Word (WO) types may exist, such as WOs on uplink subbands within downlink time slots and WOs on uplink time slots. In this case, both types of WOs may share the same WUS configuration resource and require joint downlink signal-to-WO mapping. Alternatively, even if the two types of WOs are independently configured resources, all relevant downlink signals may still be mapped to WOs. To ensure that both types of WOs can be mapped by downlink signals, different mapping orders or methods may need to be used in different specific periods. This will change the downlink signal-to-WO mapping period and also affect the determination period of the WO group.

[0473] Therefore, the following implementation methods exist: In some implementation methods, the period for determining the WO group used for multiple WUS transmissions can be determined by one or more of the following methods:

[0474] Method 1: Based on the first mapping mode period of the downlink signal to the WO (i.e., the first mapping period in the above embodiment), and the WO includes different types of WO.

[0475] Based on the first mapping mode period from downlink signal to WO, within one or more of these first mapping mode periods, for each downlink signal index (e.g., SSB index), at least one WO group can be found. This WO group contains only the uplink resource configuration for non-enhanced duplex, or the determination of this WO group is for resource determination of WUS repetitive transmission for terminals that do not support enhanced duplex. Specifically, this is for resource determination of WUS repetitive transmission for terminals that do not support enhanced duplex.

[0476] Based on the first mapping mode period from the downlink signal to the WO, within one or more of these first mapping mode periods, for each downlink signal index (e.g., SSB index), at least one WO group can be found. This WO group contains only the uplink resource configuration for enhanced duplex, or the determination of this WO group is for resource determination of WUS repetitive transmission for enhanced duplex terminals. Specifically, this is for resource determination of WUS repetitive transmission for enhanced duplex terminals.

[0477] Based on the first mapping mode period from the downlink signal to the WO, within one or more of these first mapping mode periods, for each downlink signal index (e.g., SSB index), at least one WO group can be found. This WO group contains both the non-enhanced duplex uplink resource configuration and the enhanced duplex uplink resource configuration, or the determination of this WO group is for resource determination of WUS repetitive transmissions for both enhanced duplex and non-enhanced duplex terminals. Specifically, this is the resource determination for WUS repetitive transmissions for both enhanced duplex terminals and terminals that do not support enhanced duplex.

[0478] Method 2: Based on the second mapping mode period from the downlink signal to the WO (i.e., the second mapping period in the above embodiment), and the WO is of the same type.

[0479] Based on the second mapping mode period from downlink signal to WO, within one or more N1 times the second mapping mode period, for each downlink signal index (e.g., SSB index), at least one WO group can be found. This WO group contains only the uplink resource configuration for non-enhanced duplex, or the determination of this WO group is for resource determination of WUS repetitive transmission for terminals that do not support enhanced duplex. Specifically, this is for resource determination of WUS repetitive transmission for terminals that do not support enhanced duplex.

[0480] Based on the second mapping mode period from downlink signal to WO, within one or more N1 times the second mapping mode period, for each downlink signal index (e.g., SSB index), at least one WO group can be found. This WO group contains only the uplink resource configuration for enhanced duplex, or the determination of this WO group is for the resource determination of WUS repetitive transmission for the enhanced duplex terminal. This refers to the resource determination for WUS repetitive transmission for the enhanced duplex terminal.

[0481] Where N1 is a positive integer greater than 1, or N1 is a positive integer greater than or equal to 1.

[0482] As a sub-implementation of the above embodiments, the first or second mapping mode period can also be replaced by one or the following period:

[0483] The mapping period from the downlink signal to the WO;

[0484] The correlation period from the downlink signal to the WO;

[0485] Enhance duplex configuration cycle.

[0486] The downlink signal mentioned here may be an SSB, or a CSI-RS, or a PRS, or other signal used for downlink measurement and associated with WUS transmission, or a signal triggered by WUS.

[0487] To reduce the complexity of implicitly determining the WO group resource window, the determination window for the WO group can also be explicitly configured directly through the network-side device.

[0488] In some implementations, the network-side device is configured to determine the time window for the WO group in order to identify the WO group.

[0489] This explicit configuration is primarily for situations where there are WO groups with resources under multiple duplex configurations. This can be achieved through system messages, proprietary RRC information, or physical layer signaling.

[0490] As another sub-implementation of the previous embodiment, the network configuration includes one or more of the following methods.

[0491] RRC / MAC / PDCCH configuration, for example, the RRC signaling of the serving cell Cell A can be configured to repeat the transmission of resources within a time window, whereby the WUS is used to trigger a specific reference signal (such as SSB) on Cell B.

[0492] SSB, for example, can configure the time window for determining the WUS retransmission resource in the PBCH payload. For example, in the case of supporting two-level SSB, the first-level SSB can be configured to trigger the WUS retransmission resource determination time window of the second-level SSB.

[0493] SIB1 or other system information;

[0494] Paging, for example, can indicate the time window for determining the recurring transmission resources of WUS to trigger PRACH.

[0495] The configuration granularity can be at least one of the following:

[0496] Per WO type, Per UE, TRP, SSB group, SSB, Carrier, BWP, Frequency range, Band, Band combination.

[0497] This application proposes a method for supporting WUS retransmission in enhanced duplex mode, considering whether the terminal has enhanced duplex mode capabilities, and accommodating both terminals that support and do not support enhanced duplex mode. Specifically, for WUS retransmission, it considers how to determine the WUS resource group used for WUS retransmission to support terminals with various duplex capabilities. Furthermore, to ensure that all SSBs can be mapped to WOs on uplink resources configured in non-enhanced duplex mode, it is necessary to consider how to define the time window for determining the WUS resource group. Through these methods, the robustness of WUS transmission can be improved for any type of terminal.
