Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a power method, apparatus, terminal, network-side equipment, medium, and product. Background Technology

[0002] In related technologies, wake-up signals, as a key technology for low-power design, are typically sent by network-side devices to wake up terminal devices in a sleep state. Related technologies already allow terminals to send uplink wake-up signals, enabling them to actively trigger communication with network-side devices. However, the uplink wake-up signal transmission methods in related technologies are limited and lack flexibility. To improve the flexibility of uplink wake-up signal transmission, this application considers introducing multiple types of wake-up signal transmission methods.

[0003] In related technologies, duplex enhancement mainly targets connected terminals, with the network side supporting full-duplex and the terminal side supporting half-duplex. This application, to improve the flexibility of terminal transmission, considers dynamically configuring full-duplex mode in situations such as the terminal's idle or inactive state, during cell search, or during random access.

[0004] Based on the above considerations, when the terminal sends an uplink wake-up signal, the diversity of uplink wake-up signal transmission modes may lead to uncertain signal interference, and / or, since the terminal is configured to send and receive simultaneously in full-duplex mode, the transmission of the uplink wake-up signal may introduce self-interference.

[0039] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0040] (1) Enhanced duplex mode

[0041] The main scenarios for 5G (5th Generation) mobile communication technology include Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low-Latency Communications (URLLC), and Massive Machine-Type Communication (mMTC). 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.

[0042] In this application embodiment, the enhanced duplex mode can also be described as enhanced duplex, Cross Division Duplex (XDD), Full Duplex (FD), Enhanced Full Duplex, Enhanced Full Duplex Mode, and Subband Full Duplex (SBFD). All of the above descriptions can represent the same concept. The enhanced duplex mode can also be expressed as supporting uplink subband within the downlink time unit, and / or supporting downlink subband within the uplink time unit, and / or supporting both uplink and downlink subband transmission within a flexible time unit.

[0043] When deploying traditional cellular networks, based on available spectrum and service characteristics, either Frequency Division Duplex (FDD) or Time Division Duplex (TDD) can be used. In FDD, uplink and downlink transmissions operate on different frequencies, do not interfere with each other, and can occur simultaneously. In TDD, uplink and downlink transmissions operate on the same frequency, interleaved using a time-division method. Each duplex method has its advantages and disadvantages. In NR, configuring full-duplex operation can significantly improve the latency and coverage performance of TDD systems. For example, non-overlapping subband full-duplex can improve transmission latency and enhance coverage.

[0044] For downlink slots (DL slots) (configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), the network configures the downlink bandwidth part (DL BWP) for the UE; for uplink slots (UL slots) (configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), the network configures the uplink bandwidth part (UL BWP) for the UE, for example, as follows. Figure 2 The time slots shown are slot 1 and slot 4.

[0045] For full duplex scenarios, the following scenarios (cases) are included:

[0046] Case 1: Configure DL BWP, i.e., slot 1

[0047] Case 2: Configure DL BWP and uplink subband (UL subband), i.e., slot 2.

[0048] Case 3: Configure UL BWP, i.e., slot 4

[0049] Case 4: Configure UL BWP and downlink subband (DL subband), i.e., slot 5.

[0050] For SBFD operations, 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 time-domain symbol) used by access network devices for SBFD operations can be referred to as an SBFD time unit (e.g., slot or time-domain symbol).

[0051] Under the Rel-15 communication standard, in TDD mode, the network side and the terminal can only send or receive at any given time. However, in Rel-18, the network side is full-duplex, allowing simultaneous sending and receiving, while the terminal side can only use half-duplex mode, meaning it can only send or receive at any given time. To improve the flexibility of terminal transmission, full-duplex mode on the terminal side can be considered, allowing both the network and terminal sides to send and receive simultaneously.

[0052] (2) Uplink power control

[0053] 1) Road damage compensation

[0054] Based on uplink power control in LTE systems, two path loss compensation methods are considered: full path loss compensation and partial path loss compensation. In NR systems, it can be assumed that the UE measures the Reference Signal Received Power (RSRP) using a specific type of reference signal (RS), and then uses the RSRP to derive the path loss between the UE and its associated gNB.

[0055] By taking into account the estimated path loss, the uplink transmission power from the UE can be fully or partially compensated. First, full path loss compensation maximizes fairness for cell-edge UEs; in other words, the power received by the gNB from a cell-edge UE will be comparable to the power received from a cell-center UE. On the other hand, if partial path loss compensation is used, the gNB-received power from a cell-center UE will be significantly higher than that from a cell-edge UE. Path loss for cell-edge UEs can be compensated by adjusting other power parameters or offsets to appropriately control the power received from cell-edge UEs, while the power received from cell-center UEs is often redundant due to already sufficient received power.

[0056] In the case of uplink data channel transmission, this redundant power can be used to improve spectral efficiency by applying higher modulation and coding scheme (MCS) levels (e.g., a UE in the cell center can use fewer physical resource blocks (PRBs) for the same transport block (TB) size). On the other hand, in the case of uplink control channel transmission using a fixed amount of resources, it is unclear how to use redundant power to improve spectral efficiency, since the uplink control information (UCI) size will not depend on the UE location or channel conditions. Therefore, it is best to consider full compensation for uplink control channel power control.

[0057] Furthermore, in the case of partial path loss compensation for uplink data channel transmission, the value of the partial path loss compensation factor can be used to adjust the received power difference between the UE at the cell center and the UE at the cell edge, and this value can vary depending on the cell radius and target performance.

[0058] 2) Transmit Power Control (TPC) commands

[0059] TPC commands can be used to compensate for channel changes caused by fast fading. For current LTE, the Physical Uplink Control Channel (PUCCH) power can be adjusted using TPC commands signaled in the Downlink Control Information (DCI), while the PUSCH (or Sounding Reference Signal (SRS)) power can be adjusted using TPC commands signaled in the Uplink Grant DCI. Furthermore, for uplink transmissions without a corresponding DCI, such as semi-persistent scheduling (SPS), periodic Channel State Information (CSI), or SRS, TPC commands can be signaled to a specific UE group using DCI format 3 / 3A. There are two types of TPC procedures for updating uplink transmit power: accumulative TPC and absolute TPC. Accumulative TPC is well-suited for fine-tuning UE transmit power by using relatively small steps of the TPC value. On the other hand, by using a relatively large step size for the TPC value, the absolute TPC can be used to immediately increase the UE transmit power.

[0060] 3) Additional functions of power control in NR

[0061] In NR design, deployments based on analog (or hybrid) beamforming are considered, particularly for high-frequency bands (e.g., above 6 GHz). This analog beamforming may require gNB TX / RX beam scanning (e.g., time division multiplexing (TDM) between different gNB TX / RX beams) not only for transmitting downlink common signals and information, such as synchronization signals (e.g., Primary Synchronization Signal (PSS) / Secondary Synchronization Signal (SSS) in LTE) or broadcast system information (e.g., Physical Broadcast Channel (PBCH) in LTE), but also for uplink and downlink control and data channel transmission to serve UEs located in different areas (or beam directions). In this case, it may be necessary to consider the differentiation of power control parameters between different beams of the UE, as the power required for UE performance will be different for each beam of the UE.

[0062] Typically, the amount of information transmitted through the uplink data channel is much greater than that through the uplink control channel. Therefore, the power required for uplink data transmission is also greater than that for the uplink control channel. For NR design, TDM is considered for the multiplexing structure between uplink data and control channels to reduce latency, provide flexible uplink / downlink configuration, and simulate beamforming. When uplink data and control channels are multiplexed using TDM, it is necessary to address the power imbalance between these two different channels, which may be greater than in current LTE. Furthermore, considering the various orthogonal frequency division multiplexing (OFDM) techniques used in NR (e.g., different subcarrier spacings or symbol durations), it is also necessary to handle the power transient cycles between uplink data and control channels for certain numericalities (e.g., large subcarrier spacings).

[0063] 4) Power control per TRP and per layer

[0064] For high-frequency bands in NR, the number of primary rays per TRP or individual panel may be limited. To achieve high Single User Multiple Input Multiple Output (SUMIMO) spectral efficiency, a thorough investigation of coordinated transmission schemes across multiple TRPs is needed in NR, including Coordinated Multi-Point Dynamic Point Selection (CoMP DPS) and Joint Transmission (JT). When the downlink-related DCI indicates the transmission rank and the applied coordination scheme, DCI decoding latency on the UE side can be a major issue whenever analog beamforming is applied in a given time instance. This is because DCI transmission can be performed by the serving TRP, but, as an example, actual data transmission can be performed by another TRP.

[0065] In the case of independent layer JTs, where specific layers can transmit from different TRPs, the uplink transmission power corresponding to each layer group may need to be configured and controlled by the gNB, since the path loss from different TRPs may differ. Furthermore, the individual uplink power control process for different TRPs needs further investigation in the context of uplink CoMP.

[0066] (3) PUSCH power control

[0067] The following formula is the power calculation expression for PUSCH:

[0068]

[0069] Among them, P PUSCH,b,f,c (i,j,q d ,l) represents the actual transmission power of PUSCH, which is the power at time i of PUSCH transmission in the l-th state under the j-th power control parameter set in cell c, carrier f, and uplink bandwidth b. d Index for the reference signal RS. P CMAX,f,c (i) represents the maximum transmit power that the terminal can configure under cell c and carrier f, P O_PUSCH,b,f,c (j) represents the sum of several basic transmit power values ​​of PUSCH under the j-th power control parameter set, and μ represents the coefficient related to subcarrier spacing (SCS). α represents a parameter related to the number of resource blocks (RBs) occupied by the PUSCH in cell c, carrier f, and uplink bandwidth b. b,f,c (j) represents the path loss adjustment factor determined by p0-PUSCH-Alpha configured by MSG3 or RRC and based on the SRS resource indicator (SRI) under the j-th power control parameter. b,f,c (q d ) represents the estimated downlink path loss for cell c, carrier f, and uplink bandwidth b, Δ TF,b,f,c (i) represents the power offset adjustment value determined by the MCS. If the RRC parameter enables deltaMCS and has a value of 1.25, then this MCS modulation value is determined by averaging the power value and power offset of each resource element (RE); otherwise, it is 0. b,f,c (i,l) represents the power quantity under different power control states. It is a dynamic control quantity, and the power control value is adjusted by the TPC command.

[0070] The power methods, apparatus, terminals, network-side devices, media, and products provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0071] See Figure 3 , Figure 3 This is a flowchart of a power control method provided in an embodiment of this application, used in a terminal, such as... Figure 3 As shown, the method includes the following steps:

[0072] Step 301: The terminal determines the transmission power of the first signal based on at least one of the transmission type and transmission resource type of the first signal;

[0073] The first signal is an uplink signal used to wake up the target signal and / or the target communication process.

[0074] In this embodiment of the application, the first signal can be understood as an uplink signal used for the wake-up function, that is, the terminal wakes up (or can be described as triggering) a specific target signal to perform transmission, and / or, a specific target communication process begins to be executed by transmitting the first signal uplink.

[0075] In this embodiment, the function of the first signal is for wake-up. The first signal can be a signal that reuses other functions, or it can be a signal specifically configured for wake-up. This embodiment does not specifically limit the specific type of signal. The aforementioned first signal can be WUS, or other signals, which are not limited, 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.

[0076] For ease of explanation, embodiments of this application may be described using the WUS signal. It is understood that the first signal in embodiments of this application is not limited to the WUS signal. The WUS signal is only used as an example of the first signal. In embodiments where the WUS signal is used as an example, WUS can also be replaced with other signals with wake-up function, such as PRACH and / or SRS signals with wake-up function.

[0077] Optionally, the first signal may be a Wake-up Signal (WUS), a Physical Random Access Channel (PRACH) for wake-up, and / or a Channel Sounding Reference Signal (SRS) for wake-up.

[0078] It is understood that in related technologies, the function of PRACH or SRS is generally not to wake up other signals, nor does it have this capability. In the embodiments of this application, the first signal can be a PRACH and / or SRS with wake-up function. The PRACH and / or SRS with wake-up function (first signal) can be transmitted on specific or dedicated time-frequency domain resources, or in other words, the sequence resources used are specific or dedicated.

[0079] In this embodiment, the target signal and target communication process are used to describe the awakened object, that is, the awakened object can be a communication signal or a communication process. The target signal can be any signal that needs to be triggered, and the target communication process can be any communication process that needs to be triggered; this embodiment does not impose any specific limitations on these.

[0080] Optionally, the target signal mentioned above may be at least one of the following: Physical Random Access Channel (PRACH), Synchronization Signal and PBCH block (SSB), System Information Block 1 (SIB1), Other System Information (OSI), Control Resource Set #0 (CORESET#0), Paging message, Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), ConfiguredGrant CG Physical Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS), and Common Reference Signal (CommonRS). The terminal can wake up or trigger the transmission of at least one of PRACH, SSB, SIB1, OSI, CORESET#0, Paging, Paging PDCCH, Paging PDSCH, CG PUSCH, SRS, and Common RS by sending a first signal.

[0081] Optionally, the target communication process described above can be a random access procedure, such as a four-step random access procedure (Type-1 random access procedure) and / or a two-step random access procedure (Type-2 random access procedure); it can also be a communication process such as Small Data Transfer (SDT) based on RACH or Small Data Transfer based on CG. The terminal can wake up or trigger the random access procedure by sending a first signal.

[0082] For example, in order to support the dynamic activation of specific public signals or channels, a corresponding first signal can be transmitted during cell search or random access. This first signal is used to activate / wake up the public signal or channel, such as activating the SSB channel or the PRACH channel.

[0083] The first signal is used for the wake-up process. In this embodiment, the transmission power is determined specifically based on the transmission type (or transmission method) and / or transmission resource type (or transmission resource) of the first signal, so that the transmission power of the first signal can match the different transmission methods and / or resources of the first signal, thereby improving the reliability of uplink wake-up.

[0084] Optionally, the first signal may include a sequence, or the first signal may include a sequence and a payload.

[0085] In this embodiment, the first signal may have different types and structures. Taking WUS as an example, the WUS-related signal format includes a WUS sequence and / or a WUS PUSCH (load). Optionally, the first signal may only include the sequence, or it may further include a load when the sequence is included. The load can also be described as a PUSCH.

[0086] In this embodiment of the application, the transmission mode or transmission process of the first signal can be divided into different types according to different signal compositions.

[0087] Optionally, the transmission type of the first signal includes at least one of the following:

[0088] A first transmission type, wherein the first transmission type is used to transmit a first sequence;

[0089] A second transmission type is used to transmit a second sequence and a first payload, wherein the second sequence and the first payload are transmitted through the same channel or an associated channel.

[0090] A third transmission type is used to transmit a third sequence and a second payload, the second payload being transmitted based on a feedback message of the third sequence.

[0091] In this embodiment, the wake-up process can be completed by transmitting only the sequence (e.g., the first transmission type), or it can be completed after both the sequence and the payload have been transmitted (e.g., the second transmission type or the third transmission type). Specifically, when there is payload transmission, during one wake-up process (corresponding to one completion of the first signal transmission), the payload transmission channel and the sequence transmission channel can be the same or different, and can be associated or unassociated.

[0092] For the third transmission type, the second payload being transmitted based on the feedback message of the third sequence can be understood as at least one of the following scenarios:

[0093] The terminal will send the second payload only after receiving the feedback message of the third sequence;

[0094] If the terminal receives a feedback message containing the first scheduling information of the second payload in the third sequence, the terminal transmits the second payload based on the first scheduling information.

[0095] If the terminal receives a feedback message in the channel that schedules the third sequence and contains second scheduling information for the second payload, the terminal transmits the second payload based on the second scheduling information.

[0096] In this embodiment of the application, the above feedback message can also be described as a wake-up response message, or a wake-up feedback message, or feedback information, used to provide feedback on the transmission of the first uplink signal (sequence and / or payload) during the wake-up process.

[0097] For ease of understanding, taking the transmission of the first signal as an example of WUS transmission, the WUS transmission type or process includes at least one of the following:

[0098] Type A: Wake-up process based on WUS sequence (first sequence);

[0099] Type B: A wake-up process based on the WUS sequence (or WUS preamble, or second sequence) and the WUS payload (or WUS PUSCH, or first payload). In Type B, the WUS sequence and WUS payload can reside in one channel, or simultaneously in two associated channels. These associated channels can be two channels with predefined or pre-configured offsets in the time or frequency domain. The entire wake-up process is considered complete only after both the WUS sequence and WUS payload portions have been successfully received.

[0100] The third transmission type (Type C): Wake-up process based on WUS sequence (third sequence) and PUSCH (second payload); in Type C, WUS sequence and PUSCH are two independent uplink transmissions. PUSCH transmission can be performed after the feedback signal of WUS sequence transmission is received. The entire wake-up process is only completed after PUSCH is successfully received.

[0101] In this embodiment of the application, when the terminal determines the transmission power of the first signal according to the transmission type of the first signal, it can be understood that different transmission types of the first signal correspond to corresponding transmission power parameters. For example, the first signal of the first transmission type is transmitted using the first transmission power parameter, the first signal of the second transmission type is transmitted using the second transmission power parameter, and the first signal of the third transmission type is transmitted using the third transmission power parameter. More specifically, the first sequence of the first signal can be transmitted using the fourth transmission power parameter, the second sequence of the first signal can be transmitted using the fifth transmission power parameter, the third sequence of the first signal can be transmitted using the sixth transmission power parameter, the first payload of the first signal can be transmitted using the seventh transmission power parameter, and the second payload of the first signal can be transmitted using the eighth transmission power parameter.

[0102] Optionally, the transmission resource type of the first signal includes at least one of the following:

[0103] The first transmission resource type is an enhanced full-duplex uplink resource.

[0104] The second transmission resource type is a non-enhanced duplex uplink resource.

[0105] Optionally, enhanced duplex uplink resources include at least one of the following: uplink subband resources in an uplink time unit containing downlink subbands; uplink subband resources in a downlink time unit; and uplink subband resources in a flexible time unit.

[0106] Optional, non-enhanced duplex uplink resources include: resources in the uplink time unit that only contains uplink subbands.

[0107] In this embodiment of the application, the time unit can be a time slot, a symbol, a subframe, or a sub-slot.

[0108] In this embodiment, the transmission resource type of the first signal is classified according to whether it is an enhanced-duplex uplink resource, specifically including a first transmission resource type and a second transmission resource type. That is, when the first signal is transmitted using enhanced-duplex uplink resources, the transmission resource type of the first signal is the first transmission resource type; when the first signal is transmitted using non-enhanced-duplex uplink resources, the transmission resource type of the first signal is the second transmission resource type.

[0109] When the terminal determines the transmission power of the first signal based on the transmission resource type of the first signal, it can be understood that different transmission resource types of the first signal correspond to corresponding transmission power parameters. For example, the first signal transmitted using the transmission resources of the first transmission resource type is transmitted using the ninth transmission power parameter, and the first signal transmitted using the transmission resources of the second transmission resource type is transmitted using the tenth transmission power parameter.

[0110] Optionally, the first transmission resource type includes at least one of the following:

[0111] The third type of transmission resource is the enhanced full-duplex uplink resource that does not include downlink common signals and / or broadcast signals in the time domain.

[0112] The fourth type of transmission resource is enhanced full-duplex uplink resources, which include downlink common signals and / or broadcast signals in the time domain.

[0113] And / or, the second transport resource type includes at least one of the following:

[0114] The fifth transmission resource type is a non-enhanced duplex uplink resource whose interval with the SSB within the time domain symbol is greater than or equal to a first preset value.

[0115] The sixth transmission resource type is a non-enhanced duplex uplink resource in which the interval between the transmission resource and the SSB in the time domain symbol is greater than or equal to the second preset value, and the time domain resource includes downlink common signals and / or broadcast signals.

[0116] In related technologies, time-domain formats can include the following types:

[0117] DL: The transmission direction is DL, and only DL transmission is performed;

[0118] UL: The transmission direction is UL, and only UL transmission is performed;

[0119] X: The downlink subband (DL) and uplink subband (UL) contain the transmission directions DL and UL respectively, i.e., a subband full duplex is performed.

[0120] Accordingly, in the embodiments of this application, the first signal (taking the WUS signal as an example) may include one or more of the following types:

[0121] Type 1: WUS transmission resources located on time-domain resources with time-domain format UL, which can correspond to the non-enhanced duplex uplink resources in the second transmission resource type in the embodiments of this application;

[0122] Type 2: WUS transmission resources located in time domain format X and not containing downlink common / broadcast signals (SSB / SIB / Master Information Block MIB / Paging, etc.);

[0123] Type 3: WUS transmission resources located on time-domain resources with time-domain format X and containing downlink common / broadcast signals (SSB / SIB / MIB / Paging, etc.);

[0124] Types 2 and 3 mentioned above can correspond to the uplink subband resources in the flexible time unit of the enhanced duplex uplink resources in the first transmission resource type in the embodiments of this application; they can also correspond to the third and fourth transmission resource types in the embodiments of this application.

[0125] For WUS transmission resources (such as Type 2 and Type 3) located on time-domain resources of time-domain format X, the transmission power can also be determined based on the frequency-domain location of the WUS transmission resource (including the frequency-domain resource location and / or the frequency-domain spacing with the DL transmission resource). For example, if the frequency-domain spacing between the WUS transmission resource and the DL transmission resource is >Y or <=Y, the transmission power when transmitting WUS signals using that WUS transmission resource will be different.

[0126] Type 4: WUS transmission resources located on a set of time-domain symbols with a gap exceeding a certain size between them and the SSB, and containing downlink common / broadcast signals (SSB / SIB / MIB / Paging, etc.), corresponding to the sixth transmission resource type in the embodiments of this application;

[0127] Type 5: At least one of the following: WUS transmission resources on the uplink subband of the downlink time unit, on the non-downlink subband of the uplink time unit, and on the uplink subband of the flexible time unit, corresponding to the enhanced duplex uplink resource in the first transmission resource type in the embodiments of this application.

[0128] In this embodiment, enhanced-duplex uplink resources can be further subdivided based on whether their time-domain resources include downlink common signals and / or broadcast signals. Non-enhanced-duplex uplink resources can be further subdivided based on whether their time-domain resources include downlink common signals and / or broadcast signals, the interval between the time-domain symbol and the SSB, and other conditions. That is, the first transmission type can be further subdivided into a third transmission resource type and / or a fourth transmission resource type, and the second transmission type can be further subdivided into a fifth transmission resource type and / or a sixth transmission resource type. In this embodiment, the transmit power parameters for transmitting the first signal can be determined using the third, fourth, fifth, and / or sixth transmission resource types.

[0129] In this embodiment of the application, when the transmission power of the first signal is determined according to the transmission resource type of the first signal, in addition to considering the division attributes of the resource itself (enhanced duplex uplink resources and non-enhanced duplex uplink resources), the downlink transmission characteristics in the time domain of the resource are further considered. The transmission of downlink common signals, broadcast signals and / or SSBs is used as a reference factor for the transmission power, thereby improving the rationality of the transmission power setting and thus improving the reliability of uplink wake-up.

[0130] In this embodiment of the application, when the terminal determines the transmission power of the first signal based on the transmission type and transmission resource type of the first signal, it can be understood that the transmission power of the first signal is determined comprehensively based on the different transmission types and transmission resource types of the first signal.

[0131] When a terminal operates in full-duplex mode, it is susceptible to interference from uplink signals transmitted by itself while receiving downlink data from network-side devices. This interference can also cause side-link interference to the downlink transmissions of other terminals. When a terminal transmits a first signal while receiving downlink data, the self-interference effect is related to the transmission power of the first signal; for example, higher transmission power results in greater interference. The transmission type of the first signal can vary, and the interference varies depending on the type. In this embodiment, adjusting the transmission power of the first signal based on the transmission type and transmission resource type can improve the terminal's transmission performance, particularly its full-duplex transmission performance.

[0132] Optionally, the terminal determines the transmission power of the first signal based on at least one of the transmission type and transmission resource type of the first signal, including:

[0133] The terminal determines the transmission power of the first signal based on at least one of the transmission type and transmission resource type of the first signal, and the frequency domain information of the transmission resource of the first signal; wherein, the frequency domain information of the transmission resource of the first signal includes at least one of the following: the frequency domain position of the transmission resource of the first signal; the frequency domain spacing between the transmission resource of the first signal and the downlink transmission resource within the same domain symbol.

[0134] In this embodiment of the application, the terminal determines the transmission power of the first signal. Based on considering the transmission type and / or transmission resource type of the first signal, it may further consider the frequency domain position of the transmission resource of the first signal, that is, consider the frequency domain position of the resource used to transmit the first signal; it may also consider the frequency domain spacing between the transmission resource of the first signal and the downlink transmission resource within the same domain symbol.

[0135] In 5G and future 6G systems, network-side devices and terminals may adopt full-duplex mode. For a communication device, simultaneous uplink and downlink transmissions can cause self-interference. To ensure transmission in the direction of interference, the communication device needs to have self-interference cancellation capabilities, which can be achieved by reserving a guard band (i.e., the aforementioned frequency domain spacing) between the receiving and transmitting frequency bands. Different frequency domain spacings may lead to different degrees of self-interference (for example, the larger the frequency domain spacing, the smaller the self-interference impact), resulting in differences in the required transmission power of the first signal. In this embodiment, the terminal determines the transmission power of the first signal by specifically considering the frequency domain spacing between the transmission resources of the first signal and the downlink transmission resources within the same domain symbol, which can improve the rationality of the transmission power setting and thus improve the reliability of uplink wake-up.

[0136] Optionally, the method further includes:

[0137] The terminal receives power configuration information sent by the network-side device, the power configuration information including at least one of the following: power parameters related to at least one transmission type; power parameters related to at least one transmission resource type;

[0138] The terminal determines the transmission power of the first signal based on at least one of the transmission type and transmission resource type of the first signal, including: the terminal determines the transmission power of the first signal based on at least one of the transmission type and transmission resource type of the first signal, and the power configuration information.

[0139] In this embodiment of the application, the network-side device can send power configuration information to the terminal. The power configuration information configures corresponding power parameters for each transmission type and / or transmission resource type. Then, the terminal can determine the power parameters and transmission power corresponding to the transmission of the first signal based on the specific transmission type and / or transmission resource type of the first signal and the power configuration information.

[0140] Optionally, based on the first signal including a sequence, or the first signal including a sequence and a load, the power configuration information can specifically configure power parameters for the sequence and / or configure power parameters for the load.

[0141] Optionally, when the transmission type of the first signal includes a first transmission type, a second transmission type, and / or a third transmission type, the power configuration information described above can specifically configure power parameters for at least one of the first sequence, the second sequence, the third sequence, the first load, and the second load.

[0144] Power parameters of the load associated with at least one transmission type;

[0145] Power parameters of a sequence associated with at least one transmission resource type;

[0146] Power parameters of the load associated with at least one transmission resource type;

[0147] The sequence includes at least one of a first sequence, a second sequence, and a third sequence; the load includes at least one of a first load and a second load.

[0148] Optionally, the power parameters of the sequence are related to at least one of the following: the type of the sequence, the index of the sequence, the length of the sequence, the number of repetitions of the sequence, the format of the sequence, and the cyclic shift of the sequence.

[0149] In this embodiment, the power parameter of the sequence can specifically correspond to at least one of the sequence type, index, length, repetition count, format, and cyclic shift. Optionally, the network-side device can set power parameters for different sequence types, different sequence indices, different sequence lengths, different sequence repetition counts, different sequence formats, and / or different sequence cyclic shifts. For example, a first power parameter can be configured for a first sequence, a second power parameter for a second sequence, and / or a third power parameter can be configured for a third sequence.

[0150] For ease of understanding, the following uses WUS sequences (first sequence, second sequence, and / or third sequence) as an example to illustrate the relationship between sequence and power parameter configuration.

[0151] 1) The type of sequence, for example, when the WUS sequence is a ZC (Zadoff Chu) sequence, a set of power control parameters and / or a power control method are applied; when the WUS sequence is an m sequence, another set of power control parameters and / or another power control method are applied.

[0159] In this embodiment, the power parameter can be at least one of the above-mentioned parameters, or other power parameters in related technologies, and this embodiment does not limit this. It is understood that configuring different power parameters for different first signals or different components (sequences / loads) of the first signal by the network-side device can mean that the types of configured power parameters are at least partially different, and / or the values ​​of the power parameters are at least partially different.

[0160] Optionally, the power parameters of the second payload include at least one of the following: common initial transmit power P. O_NOMINAL,PUSCH,f,c Terminal-specific initial transmit power P O_UE_PUSCH,b,f,c and power attenuation factor α b,f,c .

The foregoing description relates to P... O_PUSCH,b,f,c (j) represents the sum of several basic transmit power values ​​of PUSCH under the j-th power control parameter set. In this embodiment, the common initial transmit power P O_NOMINAL,PUSCH,f,c Terminal-specific initial transmit power P O_UE_PUSCH,b,f,cThat is, the sum of the above-mentioned basic transmission power and the two constitutes P. O_PUSCH,b,f,c (j).

[0191] Optionally, the transmit power of the second payload is determined based on at least one of the following:

[0193] In an optional embodiment, the transmit power of the payload is determined based on the transmit power of its corresponding sequence (the sequence corresponding to the first payload is the second sequence, and the sequence corresponding to the second payload is the third sequence), and / or based on the uplink power control method. Optionally, the aforementioned uplink power control method may refer to the power calculation expression of the PUSCH described above.

[0198] In an optional implementation, the transmit power of the payload can be determined by referring to the transmit power of its corresponding sequence, or by referring to its transmission resource type and / or the power configuration information sent by the network-side device.

[0199] In an optional implementation, the transmit power of the payload can be determined directly based on its corresponding sequence, without depending on the transmission resource type and / or the power configuration information sent by the network-side device.

[0200] For example, determining the transmission power of the Type B WUS PUSCH (first payload) may also include at least one of the following:

[0201] The Type B WUS sequence (second sequence) associated with this Type B WUS PUSCH transmission has the same transmission power;

[0202] The initial transmission power is the same as that of the Type B WUS sequence;

[0204] It is the same as the minimum retransmission power among multiple Type B WUS sequences;

[0205] The transmit power is determined based on uplink power control.

[0206] For example, determining the transmit power of the Type C PUSCH (second payload) may also include at least one of the following:

[0207] The transmission power is the same as the most recent transmission power of the Type C WUS sequence (third sequence). The most recent transmission power can be understood as the transmission power when the WUS sequence was successfully transmitted. For example, the transmission of the WUS sequence may have been retransmitted multiple times. The power when the last retransmission was successful is used as the transmission power of the Type C PUSCH.

[0208] It is the same as the maximum retransmission power among multiple Type C WUS sequences;

[0209] It is the same as the minimum retransmission power among multiple Type C WUS sequences;

[0214] The second resource is used to transmit the first payload;

[0216] In this embodiment of the application, different transmission resources can be determined according to different transmission types. Correspondingly, the transmission resource type of the first signal can correspond to at least one of the transmission resource types of the first resource, the second resource, and the third resource.

[0217] Optionally, the method further includes:

[0218] The terminal determines the power boosting parameters of the first signal based on the relevant information of the first signal.

[0219] In this embodiment of the application, during the retransmission and repeated transmission of the first signal, it may be necessary to increase the transmission power of the first signal. For example, if the previous transmission of the first signal fails, it may be necessary to increase the transmission power of the first signal before retransmission; as another example, for SIB1 transmission for wake-up on-demand transmission, in order to improve the success rate of wake-up, it may be necessary to repeatedly transmit the WUS signal multiple times, with the transmission power of each repeated transmission increasing by n dB based on the previous transmission, where n is a positive number.

[0220] In this embodiment of the application, determining the power boosting parameters of the first signal based on the relevant information of the first signal can be understood as determining whether to perform power boosting and how to perform power boosting based on the relevant information of the first signal.

[0221] The failure to transmit (or receive, or send) the first signal (e.g., WUS) or the sequence of the first signal (e.g., WUS sequence) and / or the payload of the first signal (e.g., WUS PUSCH) may refer to the terminal not receiving the corresponding feedback information or not receiving feedback information within a certain period of time (e.g., within the random access response window).

[0222] Optionally, the relevant information of the first signal includes at least one of the following:

[0223] The signal associated with the first signal, the signal group associated with the first signal, the carrier associated with the first signal, the carrier group associated with the first signal, the subband associated with the first signal, the transmit / receive point (TRP) associated with the first signal, the TRP group associated with the first signal, the bandwidth portion (BWP) associated with the first signal, the transmission resource type of the first signal, and the transmission type of the first signal.

[0224] In this embodiment, the relevant information of the first signal may be transmission type and / or transmission resource type. That is, the transmission type and / or transmission resource type of the first signal can be used to determine both the transmission power of the first signal and the power boosting parameters of the first signal. The relevant information of the first signal may also include information such as the signal or signal group associated with the first signal, carrier or carrier group, subband, TRP or TRP group, BWP, etc., which are specifically used to determine the power boosting parameters of the first signal.

[0225] Optionally, the signal associated with the first signal includes at least one of the following: an uplink reference signal associated with the first signal; a physical random access channel (PRACH) associated with the first signal; a downlink reference signal associated with the first signal; a paging signal associated with the first signal; and a path loss estimation reference signal associated with the first signal.

[0226] In this embodiment of the application, at least one of the aforementioned uplink reference signal, PRACH, downlink reference signal, paging signal, and path loss estimation reference signal associated with the first signal can be used to determine the power boosting parameters of the first signal.

[0227] Optionally, the power boost parameters include at least one of the following: power boost step size, power boost counter, and maximum number of power boosts.

[0228] In this embodiment, the specific parameters involved in power boosting include power boost step size, power boost counter, and maximum number of power boosts. The power boost step size can be understood as the power increase value each time; the power boost counter can be used to record the cumulative number of times the power has been boosted when the first signal is transmitted; when the power boost counter is cleared, the transmission power returns to the initial transmission power, which can be understood as the transmission power before power boosting; the maximum number of power boosts is the number of times the power is allowed to be boosted when the first signal is transmitted.

[0229] Optionally, the terminal determines the power boosting parameters of the first signal based on relevant information of the first signal, including any one of the following:

[0230] When the relevant information of the first signal changes, the terminal stops increasing the transmission power of the first signal;

[0231] When the relevant information of the first signal changes, the terminal continues to increase the transmission power of the first signal;

[0232] When the relevant information of the first signal changes, the terminal resets the power boost parameters of the first signal.

[0233] In this embodiment, changes to the relevant information of the first signal may affect the power boosting. Optionally, if any one or more of the following changes occur: the signal associated with the first signal, the signal group associated with the first signal, the carrier associated with the first signal, the carrier group associated with the first signal, the subband associated with the first signal, the transmit / receive point (TRP) associated with the first signal, the TRP group associated with the first signal, the bandwidth portion (BWP) associated with the first signal, the transmission resource type of the first signal, or the transmission type of the first signal, the power boosting of the first signal can be stopped, the power boosting of the first signal can continue, or the power boosting parameters of the first signal can be reset. Resetting the power boosting parameters of the first signal may involve clearing the power boosting counter, i.e., restoring the initial transmit power value.

[0234] Optionally, continuing to increase the transmission power of the first signal when the relevant information of the first signal changes includes:

[0235] When the relevant information of the first signal changes, the terminal performs a power boosting operation using the power boosting parameters corresponding to the changed relevant information of the first signal.

[0236] When the relevant information of the first signal changes, the terminal performs a power boosting operation using the power boosting parameters corresponding to the relevant information of the first signal before the change.

[0237] In this embodiment, the relevant information of the first signal is correlated with the power boosting parameters. For example, the first transmission resource type corresponds to the first power boosting parameter, and the second transmission resource type corresponds to the second power boosting parameter. When the relevant information of the first signal changes, and it is necessary to continue boosting the transmission power of the first signal, the power boosting parameter used can be either the boosting parameter before the change or the boosting parameter after the change. For example, when the first signal switches from the first transmission resource type to the second transmission resource type, the boosting can be performed using the first power boosting parameter, or the boosting can be performed using the second power boosting parameter; the boosting can be based on the accumulated power value or on the initial power value.

[0238] This application embodiment allows the terminal to reasonably determine the transmission power of the first signal when using different first signal transmission resource types and / or transmission types, thereby increasing the success rate of first signal transmission, avoiding power waste, and reducing the impact of self-interference, thus ensuring the receiving performance of downlink transmission.

[0239] To facilitate understanding of this application, the following uses WUS signal as the first signal as an example to illustrate the embodiments of this application.

[0240] In optional implementations, appropriate power control is performed on the transmission of WUS signals for different duplex configurations and WUS signal transmission types. Several power control methods for WUS signals are proposed, considering the following aspects:

[0241] Determining the transmit power of WUS sequences under different enhanced duplex configurations;

[0242] Determining the transmit power of WUS transmission carrying payload under different enhanced duplex configurations;

[0243] Determining the transmit power of the independent PUSCH after receiving the WUS feedback signal under different enhanced duplex configurations;

[0244] Power boost of WUS sequences under different enhanced duplex configurations;

[0245] The power increase of WUS transmission when different resource types change.

[0246] Optionally, the power control method for the WUS signal can be proposed for the transmission type and / or resource type of the WUS signal transmission in the idle / inactive state configured in full-duplex mode.

[0247] In this embodiment of the application, the time-frequency resources required to send a wake-up signal WUS can be described as WO (WUS Occasion). In this embodiment of the application, the WUS resources can be WUS time-frequency resources (such as WO) and / or WUS sequence resources.

[0248] Example 1: Determining the transmit power of WUS sequences under different enhanced duplex configurations

[0249] In some embodiments, the transmit power of the WUS sequence (including WUS sequences in Type A / B / C) is determined based on the WO resource type.

[0250] WO types include:

[0251] Type 1: WO located on a time-domain resource with a time-domain format of UL;

[0252] Type 2: WO located on time-domain resources with time-domain format X and which do not contain downlink public / broadcast signals (SSB / SIB / MIB / Paging, etc.);

[0253] Type 3: WO located on time-domain resources with time-domain format X and containing downlink public / broadcast signals (SSB / SIB / MIB / Paging, etc.);

[0254] The network is configured with different power offset values ​​for WUS sequences of type 1 / 2 / 3 respectively:

[0255] Type 1, offset 1 = 0

[0256] Type 2, offset 2 = N

[0257] Type 3, offset 3 = M

[0258] As a sub-example of the previous embodiment, when the UE selects to transmit WUS on a time-domain resource with time-domain format UL (i.e., type 1), the transmit power of the WUS sequence is determined according to the following:

[0259] P WUS,b,f,c (i)=min{P CMAX,f,c (i),P WUS,target,f,c +PL b,f,c [dBm],

[0260] Among them, P WUS,target,f,c That is, the target received power corresponding to the WUS sequence, for example, the formula for calculating its value is as follows:

[0261] wusReceivedTargetPower + (WUS_POWER_RAMPING_COUNTER – 1) × WUS_POWER_RAMPING_STEP + DELTA_WUS. Here, wusReceivedTargetPower is the initial target received power that the gNB expects to receive from the WUS sequence; WUS_POWER_RAMPING_COUNTER is the power boost counter; WUS_POWER_RAMPING_STEP is the power boost step size; and DELTA_WUS is the power offset value. The values ​​of these parameters may be related to the sequence type, index, length, repetition count, format, and cyclic shift.

[0262] PL b,f,c This represents the estimated downlink path loss for cell c, carrier f, and uplink bandwidth b;

[0263] P CMAX,f,c (i) represents the maximum transmit power that the terminal can configure in cell c and carrier f at transmission time i.

[0264] As a sub-example of the previous embodiment, when WUS is transmitted on a time-domain resource located in time-domain format X and not containing downlink common / broadcast signals (SSB / SIB / MIB / Paging, etc.) via WO (i.e., type 2), the transmit power of the WUS sequence is determined according to the following:

[0265] P WUS,b,f,c(i)=min{P CMAX,f,c (i),P WUS,target,f,c +offset2+PL b,f,c [dBm],

[0266] Furthermore, another possibility is that offset2 is reflected in P. WUS,target,f,c In the calculation formula, that is, P of different WO types. WUS,target,f,c The calculation formulas are different.

[0267] As a sub-example of the previous embodiment, when the UE selects to transmit WUS on a time-domain resource with time-domain format X and containing downlink common / broadcast signals (SSB / SIB / MIB / Paging, etc.) via WO (i.e., type 3), the transmit power of the WUS sequence is determined according to the following:

[0268] P WUS,b,f,c (i)=min{P CMAX,f,c (i),P WUS,target,f,c +offset3+PL b,f,c [dBm],

[0269] Furthermore, another possibility is that offset3 is reflected in P. WUS,target,f,c In the calculation formula, that is, P of different WO types. WUS,target,f,c The calculation formulas are different, meaning that different power offset values ​​exist in the calculation formulas.

[0270] Example 2: Determining the transmit power of WUS PUSCH transmission carrying payload under different enhanced duplex configurations

[0271] In some embodiments, when transmitting in full duplex mode, the transmit power of the Type B WUS PUSCH is determined based on the WO type.

[0272] WO types include:

[0273] Type 1: WO located on a time-domain resource with a time-domain format of UL

[0274] Type 2: WO located on time-domain resources with time-domain format X and which do not contain downlink public / broadcast signals (SSB / SIB / MIB / Paging, etc.).

[0275] Type 3: WO located on time-domain resources with time-domain format X and containing downlink public / broadcast signals (SSB / SIB / MIB / Paging, etc.).

[0276] The network is configured with different power offset values ​​for Type B WUS PUSCH for Type 1 / 2 / 3 WUS sequences respectively:

[0277] For WUS sequences using WO type 1, the corresponding Type B WUS PUSCH offset 1 = 0.

[0278] For WUS sequences using WO type 2, the corresponding Type B WUS PUSCH offset 2 = N

[0279] For WUS sequences using WO type 3, the corresponding Type B WUS PUSCH offset 3 = M

[0280] As a sub-implementation of the previous embodiment, when the UE selects to transmit the Type B WUS sequence (second sequence) on a time-domain resource with a time-domain format of UL (i.e., type 1), the transmit power of the Type B WUS PUSCH (first payload) is determined according to the following:

[0281] P typeB,PUSCH =min{P CMAX,f,c (i), P UL_PC,PUSCH [dBm],

[0282] P CMAX,f,c (i) represents the maximum transmit power that the terminal can configure in cell c and carrier f at transmission time i;

[0283] P UL_PC,PUSCH Calculate using the power calculation expression for PUSCH mentioned earlier;

[0284] As a sub-implementation of the previous embodiment, when the UE selects to transmit the Type B WUS sequence on a time-domain resource with time-domain format X that does not contain downlink common / broadcast signals (SSB / SIB / MIB / Paging, etc.), the transmit power of the Type B WUS PUSCH is determined according to the following when transmitting the Type B WUS PUSCH:

[0285] P typeB,PUSCH =min{P CMAX,f,c (i), P UL_PC,PUSCH +offset2}[dBm

[0286] As a sub-implementation of the previous embodiment, when the UE selects to transmit the Type B WUS sequence on a time-domain resource with time-domain format X and containing downlink common / broadcast signals (SSB / SIB / MIB / Paging, etc.), the transmit power of the Type B WUS PUSCH is determined according to the following when transmitting the Type B WUS PUSCH:

[0287] P typeB,PUSCH =min{P CMAX,f,c (i), P UL_PC,PUSCH +offset3}[dBm]

[0288] Example 3: Determination of the transmit power of the independent PUSCH (second payload) after receiving the WUS feedback signal under different enhanced duplex configurations.

[0289] In some embodiments, during full-duplex transmission, the transmit power of the Type C PUSCH (second payload) is determined based on the WO type.

[0290] WO types include:

[0291] Type 1: WO located on a time-domain resource with a time-domain format of UL;

[0292] Type 2: WO located on time-domain resources with time-domain format X and which do not contain downlink public / broadcast signals (SSB / SIB / MIB / Paging, etc.);

[0293] Type 3: WO located on time-domain resources with time-domain format X and containing downlink public / broadcast signals (SSB / SIB / MIB / Paging, etc.);

[0294] The network is configured with different power offset values ​​for Type C PUSCH for Type 1 / 2 / 3 WUS sequences:

[0295] For WUS sequences using WO type 1, the corresponding Type C PUSCH offset 1 = 0.

[0296] For WUS sequences using WO type 2, the corresponding Type C PUSCH offset 2 = N

[0297] For WUS sequences using WO type 3, the corresponding Type C PUSCH offset 3 = M

[0298] As a sub-example of the previous embodiment, when the UE selects to transmit WUS on a time-domain resource with time-domain format UL (i.e., type 1), the transmit power of the Type C PUSCH after receiving the WUS feedback signal is determined according to the following:

[0299] P typeC,PUSCH =min{P CMAX,f,c (i), P UL_PC,PUSCH [dBm],

[0300] P CMAX,f,c (i) represents the maximum transmit power that the terminal can configure in cell c and carrier f at transmission time i;

[0301] P UL_PC,PUSCH The power calculation expression for PUSCH is referred to above. As a sub-example of the previous embodiment, when the UE selects to transmit WUS on a time-domain resource with time-domain format X that does not contain downlink common / broadcast signals (SSB / SIB / MIB / Paging, etc.) via WO (i.e., type 2), the transmit power of the Type CPUSCH after receiving the WUS feedback signal is determined according to the following:

[0302] P typeC,PUSCH =min{P CMAX,f,c (i), P UL_PC,PUSCH +offset2}[dBm

[0303] As a sub-example of the previous embodiment, when the UE selects to transmit WUS on a time-domain resource with time-domain format X and containing downlink common / broadcast signals (SSB / SIB / MIB / Paging, etc.) via WO (i.e., type 3), the transmit power of the Type C PUSCH after receiving the WUS feedback signal is determined according to the following:

[0304] P typeC,PUSCH =min{P CMAX,f,c (i), P UL_PC,PUSCH +offset3}[dBm]

[0305] Example 4: Power boost of WUS sequences under different enhanced duplex configurations

[0306] In some embodiments, during full-duplex transmission, the power ramping step of the WUS sequence (including WUS sequences in Type A / B / C) is determined according to the WO type.

[0307] WO types include:

[0308] Type 1: WO located on a time-domain resource with a time-domain format of UL;

[0309] Type 2: WO located on time-domain resources with time-domain format X and which do not contain downlink public / broadcast signals (SSB / SIB / MIB / Paging, etc.);

[0310] Type 3: WO located on time-domain resources with time-domain format X and containing downlink public / broadcast signals (SSB / SIB / MIB / Paging, etc.);

[0311] The network is configured with different power ramping steps for WUS sequences of type 1 / 2 / 3.

[0312] Type 1, power ramping step1 = N

[0313] Type 2, power ramping step 2 = M

[0314] Type 3, power ramping step 3 = L

[0315] Furthermore, in this embodiment, when determining the transmit power of the WUS sequence, the power parameters determined in other embodiments can be used as a basis, and on this basis, the power boost step size parameters can be further determined based on the WO resources.

[0316] As a sub-implementation of the previous embodiment, when the UE selects to transmit the WUS sequence on a time-domain resource with a time-domain format of UL (i.e., type 1), the UE needs to retransmit the WUS sequence. When the UE continues to select WO type 1 to transmit the WUS sequence, the transmit power of the WUS sequence is determined according to the following:

[0317] P WUS,b,f,c (i)=min{P CMAX,f,c (i), P WUS,target,f,c +PL b,f,c +power ramping step 1} [dBm]

[0318] P CMAX,f,c (i) represents the maximum transmit power that the terminal can configure in cell c and carrier f at transmission time i;

[0319] P WUS,target,f,c That is, the target received power corresponding to the WUS sequence. For details, please refer to Example 1, which will not be repeated here.

[0320] PL b,f,c This represents the estimated downlink path loss for cell c, carrier f, and uplink bandwidth b.

[0321] Specifically, if the previous retransmission of the WUS sequence failed, it needs to be retransmitted again (i.e., a second retransmission of the WUS sequence). The transmission power of the WUS sequence is the power of the previous retransmission plus power ramping step 1, that is:

[0322] P WUS,b,f,c (i)=min{P CMAX,f,c (i), P WUS,target,f,c +PL b,f,c +power ramping step 1+

[0323] Power ramping step 1} [dBm]

[0324] or

[0325] P WUS,b,f,c (i)=min{P CMAX,f,c (i), P WUS,target,f,c +PL b,f,c +2*power ramping step1}[dBm]

[0326] In particular, another possibility is that the power increase in retransmission is reflected in P. WUS,target,f,c In the calculation formula.

[0327] As a sub-implementation of the previous embodiment, when the UE selects to transmit the WUS sequence on a time-domain resource with time-domain format X that does not contain downlink common / broadcast signals (SSB / SIB / MIB / Paging, etc.) using WO (i.e., type 2), the UE needs to retransmit the WUS sequence. When the UE continues to select WO type 2 to transmit the WUS sequence, the transmit power of the WUS sequence is determined according to the following:

[0328] P WUS,b,f,c (i)=min{P CMAX,f,c (i), P WUS,target,f,c +PL b,f,c +power ramping step 2}

[0329] As a sub-example of the previous embodiment, when the UE selects to transmit the WUS sequence on a time-domain resource with time-domain format X and containing downlink common / broadcast signals (SSB / SIB / MIB / Paging, etc.), the UE needs to retransmit the WUS sequence. When the UE continues to select WO type 3 to transmit the WUS sequence, the transmit power of the WUS sequence is determined according to the following:

[0330] P WUS,b,f,c (i)=min{P CMAX,f,c(i), P WUS,target,f,c +PL b,f,c +power ramping step 3}

[0331] As a sub-implementation of the previous embodiment, when the UE selects to transmit the WUS sequence on a time-domain resource with time-domain format UL (i.e., type 1):

[0332] The UE needs to retransmit the WUS sequence. When the UE continues to select WO type 1 to transmit the WUS sequence, the transmission power of the WUS sequence is increased according to Power ramping step 1.

[0333] When the UE needs to retransmit the WUS sequence, and the UE selects WO type 2 to transmit the WUS sequence, the transmit power of the WUS sequence is determined according to one of the following:

[0334] P WUS,b,f,c (i)=min{P CMAX,f,c (i), P WUS,target,f,c +PL b,f,c +power ramping step 1+

[0335] Power ramping step 2} (i.e., the power ramping of different WO types of WUS sequences can be accumulated)

[0336] P WUS,b,f,c (i)=min{P CMAX,f,c (i), P WUS,target,f,c +PL b,f,c +power ramping step2} (i.e., different)

[0337] The power rise of WUS sequences of type WO does not accumulate.

[0338] It should be noted that the failure to receive (or transmit, or send) the first signal (e.g., WUS) or the sequence of the first signal (e.g., WUS sequence) and / or the payload of the first signal (e.g., WUS PUSCH) can mean that the terminal did not receive the corresponding feedback information or did not receive any feedback information within a certain period of time (e.g., within the random access response window).

[0339] Example 5: Power Surge in WUS Transmission When Different Resource Types or WUS Transmission Types Change

[0340] When WUS performs retransmissions or repeated transmissions, its power resources may need to be increased. Under certain conditions, such as when the downlink carrier or carrier group associated with the retransmitted WUS resources changes, the corresponding WUS transmission may need to reset its power, recalculating the power increase from the target power to avoid power waste. Alternatively, it may continue to increase the power based on the power of the previous WUS transmission to increase the success rate of WUS transmission. Optionally, the following embodiments are available.

[0341] In some embodiments, the determination of WUS retransmission power or repeated transmission power includes one of the following indication methods:

[0342] When at least one of the following changes in the signal or signal group, carrier or carrier group, subband, TRP or TRP group, BWP, transport resource type, or transport type associated with a WUS retransmission or repeat transmission: Perform at least one of the following:

[0343] Stop WUS's power ramp-up

[0344] Reset the WUS power ramp counter;

[0345] Based on the power of the previous WUS transmission, continue to ramp up the WUS power.

[0346] Based on the power of the previous WUS transmission, the WUS power ramp-up continues and the ramp-up power step size is related to at least one of the following: new signal or signal group, carrier or carrier group, subband, TRP or TRP group, BWP, transmission resource type, and transmission type.

[0347] Based on the power of the previous WUS transmission, the power of WUS continues to ramp up, and the ramp power step size used is related to at least one of the following: the signal or signal group, carrier or carrier group, subband, TRP or TRP group, BWP, transmission resource type, and transmission type before the change.

[0348] Whether or how WUS retransmissions or repeated transmissions perform power ramp-up depends on whether the downlink reference signal or path loss estimation reference signal associated with WUS has changed. For example, if at least one of the signals or signal groups, carriers or carrier groups, subbands, TRPs or TRP groups, BWPs, transmission resource types, or transmission types associated with WUS retransmissions or repeated transmissions changes, WUS power ramp-up can only continue based on the power of the previous WUS transmission if at least the downlink reference signal or path loss estimation reference signal associated with WUS has not changed.

[0349] Optionally, the WUS retransmission / repeated transmission here can be a retransmission / repeated transmission of a WUS sequence, a retransmission / repeated transmission of a Type B WUS PUSCH, or a retransmission / repeated transmission of a Type C PUSCH.

[0350] As an optional embodiment of the above embodiment, the signal or signal group, carrier or carrier group, subband, TRP or TRP group, BWP, transmission resource type, and transmission type satisfy at least one of the following:

[0362] Transmission resource types include: enhanced duplex uplink resources and non-enhanced duplex uplink resources.

Furthermore, where SSB is mentioned in various embodiments, it can be replaced with Channel State Information Reference Signal (CSI-RS), SRS, Positioning Reference Signals (PRS), Phase-tracking Reference Signal (PTRS), and / or downlink WUS signals to form new embodiments of this application.
