[0062] Figure 6 This is a signaling interaction diagram of another typical application scenario of the present invention. Detailed Implementation

[0063] As mentioned in the background section, there is no technical solution to the resource allocation problem of the wake-up signal.

[0064] Specifically, in NR systems, synchronization signals and broadcast channel signals are transmitted in the form of Synchronization Signal and Physical Broadcast Channel Blocks (SSBs). Furthermore, 5G systems introduce beam sweeping functionality. Each synchronization signal block can be viewed as a resource corresponding to one beam during the beam sweeping process. A synchronization signal block includes a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH) signal. Multiple synchronization signal blocks form a synchronization signal burst. A synchronization signal burst can be considered as a relatively concentrated resource containing multiple beams. Multiple synchronization signal bursts form a synchronization signal burst set. Synchronization signal blocks are repeatedly transmitted on different beams to complete the beam sweeping process. Through beam sweeping training, user equipment can determine which beam receives the strongest signal.

[0065] For example, we can assume that the time-domain positions of the L synchronization signal blocks are fixed within a 5-millisecond (ms) window. That is, the transmission time and index of the synchronization signal blocks are fixed within the 5ms window. The indices of the L synchronization signal blocks are consecutively arranged in the time domain, from 0 to (L-1), where L is a positive integer.

[0066] Furthermore, the NR system introduces a new concept, "Bandwidth Part (BWP)," which allows NR UEs to access the 5G system using a narrowband BWP and transmit services using a broadband BWP. The BWP used for transmitting services is called the active BWP. For the NR system, a cell (e.g., a primary cell, PCell cell) can contain multiple BWPs, each occupying a limited bandwidth.

[0067] Furthermore, the base station can configure a Control Resource Set (CORESET) and a Search Space Set for the BWP. The CORESET includes information such as the frequency domain resource locations, time domain symbol count, and CCE-to-REG mappings of the Control Channel Element (CCE) and Resource Element Group (REG) monitored by the UE. The Search Space Set includes information such as the time slot period, the starting symbol position within the time slot, and the aggregation level of the PDCCH monitored by the UE. Each Search Space Set is bound to a Control Resource Set. The Search Space Set and its bound Control Resource Set define a set of time-frequency resources, which can be referred to as the "time-frequency resources of the Search Space Set and the corresponding Control Resource Set."

[0068] There are two types of search space sets: common search space and UE specific search space.

[0069] The UE can blindly detect PDCCH in one or more configured search space sets. Within the search space set, the UE can blindly detect candidate PDCCH according to preset rules and detect downlink control information (DCI) based on the Radio Network Temporary Identifier (RNTI).

[0070] For each search space set, the number of candidate DCIs that the UE needs to detect can be one or more.

[0071] Furthermore, Control Resource Set 0 (CORESET0) is the CORESET for the initially accessing UE to monitor the Remaining Minimum System Information (RMSI) PDCCH by default. Search Space Set 0 (SS0) is the search space set for the initially accessing UE to monitor the RMSI PDCCH by default. Search Space Set 0 is either a common search space or a common search space set. The initially accessing UE monitors candidate PDCCHs within Control Resource Set 0 and Search Space Set 0 by default; that is, Search Space Set 0 can be bound to Control Resource Set 0 by default. Search Space Set 0 and its bound Control Resource Set 0 determine a set of time-frequency resources, which can be referred to as "the time-frequency resources of Search Space Set 0 and the corresponding Control Resource Set 0". In addition, other common search space sets can also be bound to Control Resource Set 0. Other common search space sets and their bound Control Resource Set 0 determine a set of time-frequency resources, which can be referred to as "the time-frequency resources of the common search space set and the corresponding Control Resource Set 0". In addition, other public search space sets can also be bound to other control resource sets besides control resource set 0. Other public search space sets and their bound other control resource sets besides control resource set 0 determine a set of time-frequency resources. This set of time-frequency resources can be called "the time-frequency resources of the public search space set and the corresponding other control resource sets besides control resource set 0".

[0072] Typically, a UE needs to monitor the PDCCH during the on-duration of Discontinuous Reception (DRX). However, the base station may not schedule the UE or send a PDCCH to it during this DRX on-duration. In scenarios such as low mobility, the UE can detect a wake-up signal before the DRX on-duration or DRX cycle to determine whether PDCCH monitoring is necessary during that period, thereby reducing UE complexity and saving power. However, how to allocate resources for the wake-up signal and how to optimize it to better adapt to existing 5G NR systems remain unresolved.

[0073] To address the aforementioned technical problems, embodiments of the present invention provide a method for determining resources for a wake-up signal, comprising: receiving resource configuration information sent by a network; and determining the frequency domain resources and / or time domain resources configured for the wake-up signal based on the resource configuration information. The technical solution provided by these embodiments allows for flexible configuration of at least one resource in the time and frequency domains of the wake-up signal, which helps avoid resource conflicts between different wake-up signals.

[0074] To make the above-mentioned objectives, features and beneficial effects of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Figure 1 This is a flowchart illustrating a method for determining resources for a wake-up signal according to an embodiment of the present invention. The method for determining resources for a wake-up signal can be applied to the user equipment side, such as being executed by the UE. Specifically, the resource determination method may include the following steps:

[0075] Step S101: Receive resource configuration information sent by the network;

[0076] Step S102: Determine the frequency domain resources and / or time domain resources configured for the wake-up signal based on the resource configuration information.

[0077] More specifically, the wake-up signal can be a signal that the UE needs to periodically detect, which is different from the synchronization signal block. It can be used to wake up the UE to perform PDCCH detection, or to resynchronize the UE, etc.

[0078] In step S101, the network-side device (e.g., a base station) may send resource configuration information to the UE. The resource configuration information may be used to indicate the time-domain resources configured for the wake-up signal, or the frequency-domain resources configured for the wake-up signal, or the time-frequency resources configured for the wake-up signal.

[0079] In step S102, the UE can determine the frequency domain resource or time domain resource configured for the wake-up signal based on the resource configuration information.

[0080] Typically, the UE can detect the wake-up signal before the DRX on-duration or before the DRX period. The UE can also detect the wake-up signal before a configured periodicity, allowing the wake-up signal detection period to differ from the DRX period, thus increasing flexibility. Before detecting the wake-up signal, the time-frequency resources configured for the wake-up signal need to be determined so that the UE can receive the wake-up signal on those resources.

[0081] In specific implementations, the resource configuration information can be used to configure frequency domain resources for the UE. Alternatively, the resource configuration information can be used to configure time domain resources for the UE. Or, the resource configuration information can be used to configure both time domain and frequency domain resources for the UE simultaneously.

[0082] In practice, when the resource configuration information is used to configure frequency domain resources for the UE, the frequency domain resources configured by the base station for the UE can be continuous.

[0083] In specific implementations, the resource configuration information may include frequency domain offset. As a non-limiting example, if the number of Physical Resource Blocks (PRBs) configured for the wake-up signal is fixed, then this number of PRBs can be used as a preset number. This preset number is known to both the UE and the base station, requiring no setting by the base station and no signaling related to this preset number from the base station.

[0084] In specific implementation, the frequency domain offset can be the offset between the PRB (or lowest PRB) with the smallest index value in the wake-up signal and the PRB (or lowest PRB) with the smallest index value in the BWP. The BWP can be the active BWP. After the base station sends the resource configuration information to the UE, the UE can determine the starting position of the frequency domain resources of the wake-up signal based on the position information of the PRB (or lowest PRB) with the smallest index value in the BWP and the offset. Furthermore, the UE can use the PRB index corresponding to the starting position of the frequency domain resources, which is determined by the sum of the PRB index and the preset number, as the ending position of the frequency domain resources. Since the UE generally operates in a BWP, such as the active BWP, using the PRB with the smallest index value in the BWP as the reference point for the offset can reduce signaling overhead.

[0085] As a variation, the frequency domain offset can be the offset between the PRB with the smallest index value in the wake-up signal and the PRB with the smallest index value in the Common Resource Block (CRB). The PRB with the smallest index value in the Common Resource Block can also be called the CRB with the smallest index value, the Resource Block (RB) with the smallest index value, the first CRB, or CRB0. After the base station sends the resource configuration information to the UE, the UE can determine the frequency domain resource start position of the wake-up signal based on the location information of CRB0 and the offset. Furthermore, the UE can use the PRB index corresponding to the frequency domain resource start position, summed with a preset number, as the PRB index to determine the frequency domain resource end position. Using CRB0 as the reference point for the offset allows the wake-up signal to be outside the BWP, thus achieving better flexibility.

[0086] In practical implementation, this frequency domain offset can include both PRB group-level offsets and PRB-level offsets, where a PRB group comprises several PRBs. As a non-limiting example, a PRB group can be a Resource Block Group (RBG) or a Physical Resource Block Group (PRG). The UE can obtain only the PRB group-level offset, in which case the UE assumes the offset is an integer multiple of the PRB group. Alternatively, the UE can obtain both the PRB group-level and PRB-level offsets, in which case the UE can convert the offset to an integer multiple of the PRB to ultimately obtain the number of PRB offsets.

[0087] As another non-limiting example, if the number of PRBs configured for the wake-up signal is not fixed, then this number of PRBs can be sent from the base station to the UE. Specifically, after determining the number of PRBs for the wake-up signal, the base station can place the number of PRBs for the wake-up signal into the resource configuration information and send it to the UE. In this case, the resource configuration information includes the frequency domain offset and the number of PRBs configured for the wake-up signal.

[0088] In specific implementations, the number of PRBs can include both the number of PRB group-level PRBs and the number of PRB levels, where a PRB group comprises several PRBs. As a non-limiting example, a PRB group can be a Resource Block Group (RBG) or a Physical Resource Block Group (PRG). The UE can obtain only the number of PRB group-level PRBs. The UE can obtain both the offset at the PRB group level and the offset at the PRB level. The UE can convert PRB groups into the number of PRBs. This ensures both low signaling overhead and frequency domain resource granularity down to the PRB level.

[0089] In specific implementation, the frequency domain offset can be the offset between the PRB with the smallest index value in the wake-up signal and the PRB with the smallest index value in the BWP. The BWP can be the active BWP. After the base station sends resource configuration information containing the offset and the number of PRBs in the wake-up signal to the UE, the UE can determine the starting position of the frequency domain resources of the wake-up signal based on the position information of the PRB with the smallest index value in the BWP and the offset. Further, the UE can use the PRB index determined by the sum of the PRB index corresponding to the starting position of the frequency domain resources and the number of PRBs in the wake-up signal as the ending position of the frequency domain resources.

[0090] As a variation, the frequency domain offset can be the offset between the PRB with the smallest index value in the wake-up signal and the first CRB (i.e., CRB0). After the base station sends resource configuration information containing the frequency domain offset and the number of PRBs in the wake-up signal to the UE, the UE can determine the starting position of the frequency domain resources of the wake-up signal based on the location information of CRB0 and the offset. Furthermore, the UE can use the PRB index determined by the sum of the PRB index corresponding to the starting position of the frequency domain resources and the number of PRBs in the wake-up signal as the ending position of the frequency domain resources.

[0091] In specific implementations, the resource configuration information can also be Resource Indicator Vector (RIV) information, which can be used to indicate the frequency domain resources of the wake-up signal. For example, the RIV information can jointly encode the start position of the frequency domain resources of the wake-up signal and the number of PRBs in the wake-up signal into a single value. As an example of joint encoding, if the start position of the frequency domain resources of the wake-up signal is x and the number of PRBs in the wake-up signal is y, the RIV information can jointly encode x and y into z. When the user equipment receives z, it calculates the corresponding x and y. Based on the start position of the frequency domain resources of the wake-up signal and the number of PRBs contained in the RIV information, the start and end positions of the frequency domain resources of the wake-up signal can be derived. This embodiment of the invention offers high flexibility in resource configuration.

[0092] In specific implementation, the RIV information can jointly encode the start position of the frequency domain resources at the PRB group level of the wake-up signal and the number of PRB groups in the wake-up signal into a single value. For example, if the start position of the frequency domain resources at the PRB group level of the wake-up signal is x, and the number of PRB groups in the wake-up signal is y, the RIV information can jointly encode x and y into z. When the user equipment receives z, it calculates the corresponding x and y.

[0093] In specific implementations, this frequency domain offset can include both PRB group-level offsets and PRB-level offsets, with the PRB-level offsets indicated by RIV. The RIV information can jointly encode the start position of the frequency domain resources at the PRB level of the wake-up signal and the number of PRBs in the wake-up signal into a single value. For example, if the start position of the frequency domain resources at the PRB level of the wake-up signal is x, and the number of PRBs in the wake-up signal is y, the RIV information can jointly encode x and y into z. Upon receiving z, the user equipment calculates the corresponding x and y. The user equipment obtains the PRB group-level offset through base station indication, and also obtains the PRB-level offset by acquiring the RIV information.

[0094] In specific implementations, the resource configuration information may include a time-domain offset. The time-domain offset may be the number of time slots, half the number of time slots, or a portion of the number of time slots (e.g., the number of symbols in a time slot). The time-domain offset may include offsets at the time slot level and offsets at the symbol level.

[0095] As a non-limiting example, if the number of symbols configured for the wake-up signal is fixed, then the duration of those fixed symbols can be used as the preset duration (also called the preset duration). This preset duration is known to both the UE and the base station, requiring no base station configuration or signaling related to it. The preset duration can also be a preset maximum duration, meaning the base station only sends a portion of the wake-up signal symbols and does not need to reach the maximum duration.

[0096] In specific implementations, the time-domain offset can be the offset between the start position of the time-domain resources of the wake-up signal and the start position of the DRX on-duration associated with the wake-up signal, or the offset between the start position of the time-domain resources of the wake-up signal and the start position of the DRX cycle associated with the wake-up signal. After the base station sends the resource configuration information to the UE, the UE can determine the start position of the time-domain resources of the wake-up signal based on the start position information of the DRX on-duration or DRX cycle associated with the wake-up signal and the offset.

[0097] In a specific implementation, the time-domain offset can be the offset between the starting position of the wake-up signal and the configured periodic time of the wake-up signal. After the base station sends the resource configuration information to the UE, the UE can determine the starting position of the time-domain resources of the wake-up signal based on the starting position information of the configured periodic time of the wake-up signal and the offset.

[0098] In practice, this time-domain offset can include both time-slot-level and symbol-level offsets. The UE can obtain only the time-slot-level offset, assuming it's an integer multiple of the time slot. Alternatively, the UE can obtain both the time-slot-level and symbol-level offsets, converting the offsets to integer multiples of the symbols to ultimately obtain the number of symbol offsets.

[0099] Furthermore, the UE can use the symbol position determined by the sum of the start position of the time-domain resource and the preset duration as the end position of the time-domain resource.

[0100] As another non-limiting example, if the number of symbols configured for the wake-up signal is not fixed, the base station can send the duration information of the wake-up signal (e.g., the duration of the wake-up signal) to the UE. The duration information of the wake-up signal can also be referred to as the duration information of the wake-up signal. In this case, the resource configuration information may include the time-domain offset and the duration information of the wake-up signal. The duration information can be the duration of the wake-up signal or the maximum duration. When the maximum duration is configured, the base station can send only a portion of the symbols of the wake-up signal without needing to reach the maximum duration.

[0101] In specific implementations, the duration or maximum duration of the wake-up signal can include both time slot-level and symbol-level durations. The UE may obtain only the time slot-level duration, or it may obtain both. Alternatively, the UE can convert the time slot-level duration to a symbol-level duration. This ensures both low signaling overhead and symbol-level granularity of the duration.

[0102] Specifically, after determining the duration information of the wake-up signal, the base station can incorporate the duration information of the wake-up signal into the resource configuration information and send it to the UE. At this time, the resource configuration information may include the time-domain offset and the duration of the wake-up signal, or the resource configuration information may include the time-domain offset and the maximum duration of the wake-up signal. In this case, the UE can use the start position of the time-domain resource and the duration information as the end position of the time-domain resource.

[0103] In specific implementations, the resource configuration information can also be Start and Length Indicator Value (SLIV) information. The SLIV information can be used to indicate the time-domain resources of the wake-up signal. For example, the SLIV information can jointly encode the start position of the time-domain resources of the wake-up signal and the duration information of the wake-up signal into a single value, where the duration information can be the duration or maximum duration of the wake-up signal. As an example of joint encoding, if the start position of the time-domain resources of the wake-up signal is x and the duration information of the wake-up signal is y, the SLIV information can jointly encode x and y into z. When the user equipment receives z, it calculates the corresponding x and y. After the UE receives the SLIV information sent by the base station, the UE can deduce the start and end positions of the time-domain resources of the wake-up signal based on the start and duration information of the time-domain resources contained in the SLIV information. This embodiment of the invention offers high flexibility in resource configuration.

[0104] In specific implementation, the SLIV information can jointly encode the start position of the time-domain resource at the time slot level of the wake-up signal and the duration information at the time slot level of the wake-up signal into a single value. For example, if the start position of the time-domain resource at the time slot level of the wake-up signal is x, and the duration information at the time slot level of the wake-up signal is y, the SLIV information can jointly encode x and y into z. When the user equipment receives z, it calculates the corresponding x and y.

[0105] In specific implementations, the time-domain offset can include a slot-level offset and a symbol-level offset, where the symbol-level offset is indicated by SLIV. The SLIV information can jointly encode the symbol-level start position of the wake-up signal's time-domain resources and the symbol-level duration information of the wake-up signal into a single value. For example, if the symbol-level start position of the wake-up signal's time-domain resources is x, and the symbol-level duration information of the wake-up signal is y, the SLIV information can jointly encode x and y into z. Upon receiving z, the user equipment calculates the corresponding x and y. The user equipment obtains the slot-level offset by acquiring the duration information of the wake-up signal, and the user equipment obtains the symbol-level offset by acquiring the SLIV information.

[0106] In specific implementation, the resource configuration information is used to jointly configure the frequency domain resources and time domain resources of the wake-up signal for the UE.

[0107] Specifically, the resource configuration information may include: resource grid information of the wake-up signal, wherein the resource grid information includes multiple candidate time-frequency resource units (RPUs). Each candidate RPU may include x consecutive PRBs and y consecutive symbols, where x and y are positive integers. The UE's wake-up signal may consist of N RPUs, and the RPUs of the wake-up signal may be discontinuous.

[0108] In practice, after determining the candidate time-frequency resource elements for the wake-up signal, the base station can send the resource configuration information via RRC signaling. Upon receiving the resource configuration information, the UE can obtain the resource grid information for the wake-up signal. Here, the RRC signaling can be system information, allowing it to be broadcast to multiple UEs and reducing signaling overhead.

[0109] For the base station, after sending the resource configuration information, it can also send resource indication information to the UE to indicate the time-frequency resource unit configured for the wake-up signal. The resource indication information can indicate the time-frequency resource unit configured for the wake-up signal using a bitmap or index. After receiving the resource indication information, the UE can obtain the time-frequency resources for the wake-up signal. The resource indication information can be transmitted to the UE via RRC signaling. This RRC signaling can be dedicated RRC signaling, allowing connected UEs to configure resources for different wake-up signals.

[0110] As a variation, the resource indication information may be transmitted to the UE via a Medium Access Control (MAC) Protocol Data Unit (PDU) or a MAC Control Element (CE). Alternatively, the resource indication information may be transmitted to the UE via DCI.

[0111] In practice, after determining the candidate time-frequency resource elements for the wake-up signal, the base station can send the resource configuration information via system information. Upon receiving the resource configuration information, the UE can obtain the resource grid information for the wake-up signal. Here, the RRC signaling can be system information, allowing it to be broadcast to multiple UEs and reducing signaling overhead.

[0112] For the base station, after sending the resource configuration information, it can also send resource indication information to the UE to indicate the time-frequency resource unit configured for the wake-up signal. The resource indication information can indicate the time-frequency resource unit configured for the wake-up signal using a bitmap or index. After receiving the resource indication information, the UE can obtain the time-frequency resources for the wake-up signal. The resource indication information can be transmitted to the UE via RRC signaling, MAC PDU, MAC CE, or DCI. The RRC signaling here can be dedicated RRC signaling, allowing connected UEs to configure resources for different wake-up signals.

[0113] Those skilled in the art will understand that the resources configured for the wake-up signal may completely or partially overlap with reserved resources. When a symbol in the wake-up signal completely or partially overlaps with a reserved resource, the base station may postpone transmitting the symbol of the wake-up signal until the symbol of the wake-up signal no longer completely or partially overlaps with the reserved resource. Correspondingly, the UE may postpone receiving the symbol of the wake-up signal to avoid the symbol of the wake-up signal completely or partially overlapping with the reserved resource. Alternatively, when multiple symbols of the wake-up signal completely or partially overlap with reserved resources, the base station may postpone transmitting the symbol of the wake-up signal until the symbol of the wake-up signal no longer completely or partially overlaps with the reserved resource, and the base station may discard symbols that exceed the duration or maximum duration. Correspondingly, the UE may postpone receiving the symbol of the wake-up signal to avoid the symbol of the wake-up signal completely or partially overlapping with the reserved resource, and the UE may ignore symbols that exceed the duration or maximum duration. Alternatively, when the symbol of the wake-up signal completely or partially overlaps with the reserved resources, the base station can transmit the overlapping portion of the wake-up signal via a punch-hole, and correspondingly, the UE can receive the overlapping portion of the wake-up signal via a punch-hole. The reserved resources may include synchronization signal blocks or other signals or channels, which will not be listed here.

[0114] The reserved resources may be time-frequency resources of synchronization signal blocks, time-frequency resources of search space sets and corresponding control resource sets, rate matching resources (RMR), time-frequency resources of PDCCH, or time-frequency resources of channel state information reference signals (CSI-RS), etc.

[0115] If the number of remaining symbols or the remaining duration of the wake-up signal after discarding symbols is less than a preset threshold, the UE will assume that the wake-up signal does not need to be detected and directly enter the DRX on duration, which helps to ensure the detection performance of the wake-up signal.

[0116] When the base station determines that it will send the wake-up signal on the time-frequency resources specified in the wake-up signal, the UE will receive the wake-up signal on the determined resources. Afterwards, the base station may send other signals, such as a tracking reference signal, after sending the wake-up signal. The tracking reference signal may include an aperiodic tracking reference signal. The aperiodic tracking reference signal may be sent via RRC signaling.

[0117] In specific implementation, when the UE detects a wake-up signal in the Nth time slot, the UE can detect the aperiodic tracking reference signal (A-TRS) carried by the RRC signaling, MAC PDU, or MAC CE in the (N+K)th time slot, where K≥0. The aperiodic tracking reference signal is also called the aperiodic channel state indicator (CSI) reference signal for tracking. The UE can obtain the aperiodic tracking reference signal associated with the wake-up signal by receiving signaling sent by the base station. The value of K is also indicated to the UE in advance by the base station through RRC signaling, MAC PDU, or MAC CE.

[0118] In practice, the UE can know the periodic tracking reference signal associated with the wake-up signal in advance. For example, the UE can obtain the periodic tracking reference signal associated with the wake-up signal by receiving signaling from the base station, and further obtain the non-periodic tracking reference signal associated with the periodic tracking reference signal.

[0119] When the UE detects the wake-up signal in the Nth time slot, if the UE expects to receive the periodic tracking reference signal associated with the wake-up signal in the (N+L)th to (N+L+Q)th time slot, and (N+L+Q)≤(N+K), then the UE does not need to detect the non-periodic tracking reference signal in the (N+K)th time slot, so as to save power consumption.

[0120] After detecting a wake-up signal in the Nth time slot, the UE can monitor the PDCCH in the (N+K+P)th time slot, where L≥0, Q≥0, and P≥0. The values ​​of L, Q, K, and P can all be indicated by RRC signaling, MAC PDU, or MAC CE.

[0121] Figure 2This is a flowchart illustrating a method for configuring resources for a wake-up signal according to an embodiment of the present invention. The method for configuring resources for a wake-up signal can be applied to the network side, for example, by a base station on the network side.

[0122] Specifically, the method may include the following steps:

[0123] Step S201: Determine the starting position of the time-domain resources and / or frequency-domain resources of the wake-up signal to obtain resource configuration information;

[0124] Step S202: Send the resource configuration information to the user equipment.

[0125] In step S201, in a specific implementation, the base station can determine at least one resource location information among the time-frequency resources configured for the wake-up signal, and use the determined resource location information as resource configuration information.

[0126] In step S202, the base station may send the resource configuration information to the UE. It should be noted that the resource configuration information may be transmitted via system information or via RRC signaling.

[0127] In a specific implementation, the PRB configured for the wake-up signal can be continuous, and the resource configuration information is used to indicate the frequency domain resources of the wake-up signal. In this case, the resource configuration information may include a frequency domain offset.

[0128] As a non-limiting embodiment, the frequency domain offset refers to the offset between the PRB of the minimum index of the wake-up signal and the PRB of the minimum index of the BWP.

[0129] As an alternative example, the frequency domain offset refers to the offset between the minimum index PRB of the wake-up signal and the first CRB.

[0130] When the number of PRBs configured for the wake-up signal is a preset number, the UE can determine the frequency domain resource start position of the wake-up signal based on the offset. Then, the frequency domain resource end position of the wake-up signal can be further determined based on the frequency domain resource start position and the preset number.

[0131] When the number of PRBs configured for the wake-up signal is variable, the resource configuration information also includes the number of PRBs configured for the wake-up signal. In this case, the UE can determine the frequency domain resource start position of the wake-up signal based on the offset. Then, the frequency domain resource end position of the wake-up signal can be further determined based on the frequency domain resource start position and the number of PRBs in the resource configuration information.

[0132] As another alternative, the resource configuration information may include RIV information, which indicates the frequency domain resources of the wake-up signal, so that the UE can determine the frequency domain resources of the wake-up signal based on the RIV information.

[0133] In specific implementations, the wake-up signal may be configured with consecutive symbols, and the resource configuration information may include a time-domain offset.

[0134] As a non-limiting embodiment, the time-domain offset refers to the offset between the start position of the time-domain resources of the wake-up signal and the start position of the DRX on duration associated with the wake-up signal, or the time-domain offset refers to the offset between the start position of the time-domain resources of the wake-up signal and the start position of the DRX period associated with the wake-up signal. If the duration information of the wake-up signal is a preset duration, the UE can determine the start position of the time-domain resources of the wake-up signal based on the offset. Then, the frequency-domain resource end position of the wake-up signal can be further determined based on the start position of the time-domain resources and the preset duration.

[0135] As an alternative example, when the duration information of the wake-up signal is a variable, the resource configuration may further include the duration information of the wake-up signal, which is the duration of the wake-up signal or its maximum duration. The UE can determine the time-domain resource start position of the wake-up signal based on the offset. Then, the frequency-domain resource end position of the wake-up signal can be further determined based on the time-domain resource start position and the duration information in the resource configuration information.

[0136] As another alternative, the resource configuration information may include SLIV information, which indicates the time-domain resources of the wake-up signal, so that the UE can determine the time-domain resources of the wake-up signal based on the SLIV information.

[0137] As another non-limiting embodiment, in a specific implementation, the resource configuration information may include: the resource grid information of the wake-up signal, wherein the resource grid information includes multiple candidate time-frequency resource units.

[0138] After sending the resource configuration information, the base station can also send resource indication information to the user equipment. This resource indication information can be used to indicate the time-frequency resource unit configured for the wake-up signal, enabling the user equipment to determine the time-frequency resource configured for the wake-up signal based on the resource indication information and the resource grid information. The resource indication information is transmitted via RRC signaling, MAC PDU, MAC CE, or DCI.

[0139] In specific implementation, the resource indication information can indicate the time-frequency resource unit configured by the wake-up signal through a bitmap or index.

[0140] Subsequently, the base station can also determine whether to send the wake-up signal in the time-frequency resources of the wake-up signal; if so, the wake-up signal is sent. If the time slot for sending the wake-up signal is time slot N, a preset signal is sent in time slot (N+K), where N and K are non-negative integers, and the preset signal includes a tracking reference signal.

[0141] The tracking reference signal may include an aperiodic tracking reference signal, which is associated with the wake-up signal. The aperiodic tracking reference signal may be transmitted via RRC signaling.

[0142] It should be noted that when the wake-up signal is sent in time slot N, if the base station will send a periodic tracking reference signal associated with the wake-up signal in time slot (N+L) to time slot (N+L+Q), and (N+L+Q)≤(N+K), then the base station will not send the non-periodic tracking reference signal in time slot (N+K).

[0143] Furthermore, the base station can also transmit PDCCH in time slots (N+K+P), where P is a non-negative integer. The values ​​of K and P are indicated by RRC signaling, MAC PDU, or MAC CE.

[0144] Those skilled in the art will understand that steps S201 to S202 can be considered as the above. Figure 1 The execution steps S101 to S102 in the illustrated embodiment correspond to each other, and they are complementary in their specific implementation principles and logic. Therefore, for the explanation of the terms used in this embodiment, please refer to... Figure 1 The relevant descriptions of the embodiments shown will not be repeated here.

[0145] Therefore, by adopting the technical solution provided in the embodiments of the present invention, the UE can determine the resources configured for the wake-up signal based on the resource configuration information sent by the base station, or the resource configuration information and resource indication information. Flexible resource configuration for wake-up signals by the base station helps avoid resource conflicts between different wake-up signals, and is particularly beneficial for the flexible allocation of resources for connected UEs.

[0146] Figure 3 This is a schematic diagram of a wake-up signal resource determination device according to an embodiment of the present invention. The wake-up signal resource determination device 3 (hereinafter referred to as resource determination device 3) can be applied to the user equipment side, for example, executed by the UE. Those skilled in the art will understand that the embodiments of the present invention can be used to implement the above-described... Figure 1 The method and technical solution shown.

[0147] Specifically, the resource determination device 3 may include: a first receiving module 31, adapted to receive resource configuration information sent by the network; and a first determining module 32, adapted to determine the frequency domain resources and / or time domain resources configured for the wake-up signal based on the resource configuration information. The resource configuration information may be transmitted via system information, or it may be transmitted via RRC signaling.

[0148] The wake-up signal is configured with a continuous PRB, and the resource configuration information includes a frequency domain offset.

[0149] In a specific implementation, the frequency domain offset refers to the offset between the PRB of the minimum index of the wake-up signal and the PRB of the minimum index of the BWP.

[0150] As a variation, the frequency domain offset refers to the offset between the PRB index of the minimum index of the wake-up signal and the first CRB.

[0151] In a specific implementation, the number of PRBs configured for the wake-up signal is a preset number. The first determining module 32 may include: a first determining submodule 321, adapted to determine the frequency domain resources configured for the wake-up signal based on the offset included in the resource configuration information and the preset number.

[0152] As an alternative example, the resource configuration information may also include the number of PRBs configured for the wake-up signal. The first determining module 32 may include a second determining submodule 322, adapted to determine the frequency domain resources configured for the wake-up signal based on the offset and the number of PRBs included in the resource configuration information.

[0153] In a specific implementation, the resource configuration information may include RIV information, which is used to indicate the frequency domain resources of the wake-up signal.

[0154] In specific implementations, the wake-up signal is configured with continuous symbols, and the resource configuration information may include a time-domain offset.

[0155] As a non-limiting example, the time-domain offset refers to the offset between the start position of the time-domain resource of the wake-up signal and the start position of the DRX on duration associated with the wake-up signal, or the offset between the start position of the time-domain resource of the wake-up signal and the start position of the DRX cycle associated with the wake-up signal. The duration of the wake-up signal is a preset duration. The first determining module 32 may include: a third determining submodule 323, adapted to determine the time-domain resource of the wake-up signal based on the offset included in the resource configuration information and the preset duration.

[0156] As an alternative example, the time-domain offset refers to the offset between the start position of the time-domain resource of the wake-up signal and the start position of the DRX on duration associated with the wake-up signal, or between the start position of the time-domain resource of the wake-up signal and the start position of the DRX cycle associated with the wake-up signal. The resource configuration information also includes the duration information of the wake-up signal, which is the duration or maximum duration of the wake-up signal. The first determining module 32 may include: a fourth determining submodule 324, adapted to determine the time-domain resource of the wake-up signal based on the offset included in the resource configuration information and the duration information.

[0157] As another alternative example, the resource configuration information may include SLIV information, which is used to indicate the time-domain resources of the wake-up signal.

[0158] In a specific implementation, the resource configuration information includes: resource grid information of the wake-up signal, the resource grid information including multiple candidate time-frequency resource units. In this case, the resource determination device 3 may further include: a second receiving module 33, adapted to receive resource indication information sent by the network, the resource indication information being used to indicate the time-frequency resource unit configured for the wake-up signal; and a second determining module 34, adapted to determine the time-frequency resource configured for the wake-up signal based on the resource indication information and the resource grid information.

[0159] The resource indication information indicates the time-frequency resource unit configured for the wake-up signal via a bitmap or index. The resource indication information may be received via RRC signaling, MAC PDU, MAC CE, or DCI.

[0160] Furthermore, the resource determination device 3 may also include: a first detection module 35, adapted to detect the wake-up signal at a determined time-frequency resource.

[0161] Furthermore, the resource determination device 3 may also include: a second detection module 36, which is adapted to detect a preset signal in time slot (N+K) if the time slot of the detected wake-up signal is time slot N. The preset signal includes a tracking reference signal, where N and K are non-negative integers.

[0162] The tracking reference signal includes an aperiodic tracking reference signal, which is associated with the wake-up signal. The aperiodic tracking reference signal may be received via RRC signaling.

[0163] Furthermore, when the wake-up signal is detected in time slot N, if a periodic tracking reference signal associated with the wake-up signal can be received in time slot (N+L) to time slot (N+L+Q), and (N+L+Q)≤(N+K), then the second detection module 36 is adapted to ignore the detection of the non-periodic tracking reference signal in time slot (N+K).

[0164] Furthermore, the resource determination device 3 may also include a third detection module 37, adapted to detect the PDCCH in time slot (N+K+P), where P is a non-negative integer. The values ​​of K and P are indicated by RRC signaling, MAC PDU, or MAC CE.

[0165] For more information on the working principle and operation mode of the resource determination device 3, please refer to the above. Figure 1 The relevant descriptions in the text will not be repeated here.

[0166] Figure 4 This is a resource configuration device for a wake-up signal according to an embodiment of the present invention. The resource configuration device 4 for the wake-up signal (hereinafter referred to as resource configuration device 4 for simplicity) can be applied to the network side, for example, executed by a base station on the network side. Those skilled in the art will understand that this embodiment of the present invention can be used to implement the above-described... Figure 2 The method and technical solution shown.

[0167] Specifically, the resource configuration device 4 may include: a first determining module 41, adapted to determine the time-domain resources and / or frequency-domain resources of the wake-up signal to obtain resource configuration information; and a first sending module 42, adapted to send the resource configuration information to the user equipment. The resource configuration information may be transmitted via system information transmission, or it may be transmitted via RRC signaling.

[0168] In specific implementations, the wake-up signal can be configured with a continuous PRB, and the resource configuration information includes a frequency domain offset.

[0169] As a non-limiting example, the frequency domain offset refers to the offset between the PRB of the minimum index of the wake-up signal and the PRB of the minimum index of the BWP.

[0170] As yet another non-limiting example, the frequency domain offset refers to the offset between the minimum index of the wake-up signal, the PRB index, and the first CRB.

[0171] Furthermore, the resource configuration information may also include the number of PRBs configured for the wake-up signal.

[0172] As another non-limiting example, the resource configuration information includes RIV information, which is used to indicate the frequency domain resources of the wake-up signal.

[0173] In specific implementations, the symbols configured for the wake-up signal can be continuous, and the resource configuration information includes a time-domain offset. The time-domain offset refers to the starting position of the time-domain resource of the wake-up signal relative to the starting position of the DRX on-duration associated with the wake-up signal, or the time-domain offset refers to the offset between the starting position of the time-domain resource of the wake-up signal and the starting position of the DRX cycle associated with the wake-up signal.

[0174] Furthermore, when the number of symbols configured for the wake-up signal is a variable, the resource configuration also includes the duration information of the wake-up signal, which is the duration of the wake-up signal or the maximum duration.

[0175] As another non-limiting example, the resource configuration information may include SLIV information, which indicates the time-domain resources of the wake-up signal.

[0176] In a specific implementation, the resource configuration information may include: resource grid information of the wake-up signal, wherein the resource grid information includes multiple candidate time-frequency resource units. In this case, the resource configuration device may further include: a second sending module 43, adapted to send resource indication information to the user equipment, wherein the resource indication information is used to indicate the time-frequency resource unit configured for the wake-up signal, so that the user equipment determines the time-frequency resource configured for the wake-up signal based on the resource indication information and the resource grid information.

[0177] The resource indication information indicates the time-frequency resource unit configured for the wake-up signal via a bitmap or index. The resource indication information may be transmitted via RRC signaling, MAC PDU, MAC CE, or DCI.

[0178] Furthermore, the resource configuration device 4 may further include: a second determining module 44, adapted to determine whether to send the wake-up signal on the time-frequency resource of the wake-up signal; and a third sending module 45, if so, the third sending module 45 is adapted to send the wake-up signal.

[0179] Furthermore, the resource configuration device 4 may also include: a fourth sending module 46, which is adapted to send a preset signal in time slot (N+K) if the time slot for sending the wake-up signal is time slot N, where N and K are non-negative integers, and the preset signal includes a tracking reference signal.

[0180] The tracking reference signal may include an aperiodic tracking reference signal, which is associated with the wake-up signal. The aperiodic tracking reference signal may be transmitted via RRC signaling.

[0181] It should be noted that when the wake-up signal is sent in time slot N, if a periodic tracking reference signal associated with the wake-up signal is sent in time slot (N+L) to time slot (N+L+Q), and (N+L+Q)≤(N+K), then the fourth sending module 46 is also used to stop sending the non-periodic tracking reference signal in time slot (N+K).

[0182] Furthermore, the resource allocation device 4 may also include a fifth transmission module 47, adapted to transmit PDCCH in time slot (N+K+P), where P is a non-negative integer. The values ​​of K and P are indicated by RRC signaling, MAC PDU, or MAC CE.

[0183] For more information on the working principle and operation mode of the resource allocation device 4, please refer to the above. Figure 2 The relevant descriptions in the text will not be repeated here.

[0184] The following section further elaborates on the signaling interaction between user equipment and network (e.g., NR base station) using typical application scenarios.

[0185] In a typical application scenario, refer to Figure 5 After user equipment 1 connects to base station 2 in the network, base station 2 can first perform operation s1, that is, determine the time and frequency resources of the wake-up signal and obtain resource configuration information.

[0186] When the resource configuration information is used to indicate the frequency domain resources of the wake-up signal and the frequency domain resources of the wake-up signal are continuous resources, if the number of PRBs configured in the wake-up signal is a preset number, then the wake-up signal may only include the frequency domain offset; if the number of PRBs configured in the wake-up signal is a variable, then the wake-up signal may include both the frequency domain offset and the number of PRBs configured in the wake-up signal. As an alternative embodiment, the resource configuration information may also include RIV information for indicating the frequency domain resources of the wake-up signal. For example, the RIV information may include the starting position of the frequency domain resources and the number of PRBs configured in the wake-up signal.

[0187] When the resource configuration information is used to indicate the time-domain resources of the wake-up signal and the time-domain resources of the wake-up signal are continuous resources, if the duration of the wake-up signal is a preset duration, then the wake-up signal may only include the time-domain offset; if the duration of the wake-up signal is a variable, then the wake-up signal may include the duration or maximum duration of the wake-up signal in addition to the time-domain offset. As an alternative embodiment, the resource configuration information may also include SLIV information for indicating the time-domain resources of the wake-up signal. For example, the SLIV information may include the start position of the time-domain resources and duration information, wherein the duration information is the duration or maximum duration of the wake-up signal.

[0188] Then, base station 2 can perform operation s2, which is to send the resource configuration information to user equipment 1.

[0189] Furthermore, upon receiving the resource configuration information, user equipment 1 can perform operation s3, that is, determine the resource configured for the wake-up signal based on the resource configuration information.

[0190] In yet another typical application scenario, refer to Figure 6 After user equipment 1 connects to base station 2 in the network, base station 2 can first perform operation s1, that is, determine the time-frequency resources of the wake-up signal and obtain resource configuration information. The resource configuration information may include: the resource grid information of the wake-up signal, and the resource grid information includes multiple candidate time-frequency resource units.
