[0002] This application claims priority to Chinese Patent Application No. 202411577420.6, filed in China on November 6, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of electronic communication technology, specifically relating to a method for determining transmission parameters, a terminal, and a network-side device. Background Technology

[0004] With the development of mobile communication technology, network-side equipment determines transmission parameters and sends them to the terminal based on the mapping relationship between the downlink transmission environment and transmission parameters. The terminal then receives the signals sent by the network-side equipment based on these transmission parameters.

[0005] In related technologies, because the transmission parameters are semi-statically configured by the network-side equipment, they cannot be adjusted in a timely manner according to changes in the terminal's wireless communication environment. This leads to the terminal receiving signals using unsuitable transmission parameters, resulting in low signal reception efficiency. To address this, the terminal can typically monitor the signaling indicating the transmission parameters carried on the Physical downlink control channel (PDCCH) in real time, and receive signals according to the transmission parameters indicated by the signaling.

[0006] However, with frequent changes in the wireless communication environment, there will be a significant increase in signaling overhead, leading to a waste of resources. Summary of the Invention

The term "base station" is not limited to any specific technical terminology. It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station.

[0044] The following is an explanation of the technical terms used in the embodiments of this application:

[0045] Low-power receiver:

[0046] This refers to a low-power wake-up radio (LP-WUR) or an almost zero-power wake-up radio (AZP-WUR). The basic working principle of an LP-WUR is that the receiver consists of a first module and a second module. The first module is the main communication module, used for transmitting and receiving mobile communication data. The second module is a low-power receiver module, also called a low-power wake-up receiver module, used to receive the wake-up signal. In power-saving mode, the terminal activates the low-power receiver module to listen for LP-WUR and disables the main communication module. When downlink data arrives, the network sends a wake-up signal to the terminal. After the terminal detects the wake-up signal through the low-power receiver module, it triggers the main communication module to turn on after a series of checks. At this time, the low-power receiver module turns off. The low-power wake-up receiver module can be continuously or intermittently activated, and when activated, it can receive low-power wake-up signals.

[0047] Low-power wake-up signal:

[0048] To reduce receiving activity in standby mode and effectively shut down the radio frequency (RF) and modem modules, thereby significantly reducing power consumption during communication reception, this can be achieved by introducing a near-zero power receiver into the terminal's receiver module. This near-zero power receiver eliminates the need for complex RF module signal detection, such as amplification, filtering, and quantization, as well as modem signal processing; it relies solely on passive matched filtering and low-power signal processing.

[0049] On the base station side, by triggering a wake-up signal on demand, the receiver with near-zero power can be activated to receive the activation notification, thereby triggering a series of processes within the terminal, such as turning on the radio frequency transceiver and baseband processing modules.

[0050] These wake-up signals are typically simple on-off keying signals with a time-domain pattern. The receiver can then detect the wake-up notification through simple energy detection and subsequent sequence detection and recognition. Furthermore, while the terminal is activating its low-power wake-up receiver to receive the wake-up signal, the main receiver module can maintain a low power consumption level, thus saving power by receiving the wake-up signal.

[0051] Adaptive modulation method for downlink transmission:

[0052] In New Radio (NR) or Long Term Evolution (LTE) systems, the Physical Downlink Shared Channel (PDSCH), Physical Downlink Control Channel (PDCCH), Physical Uplink Shared Channel (PUSCH), and Physical Uplink Control Channel (PUCCH) all support dynamic adjustment of time, frequency, and spatial resources based on channel changes, using different modulation and coding schemes to achieve adaptive adjustment. For example, adaptive adjustment of the downlink data channel (PDSCH) can be indicated by the Downlink Control Information (DCI) of the PDSCH. Multiple MCSs can be semi-statically configured at higher layers, with one MCS dynamically indicated by the DCI. Furthermore, the DCI can dynamically indicate the PRB and OFDM symbol counts, as well as QCL parameters. Adaptive adjustment of the PDCCH can be achieved by configuring multiple different aggregation levels (ALs). The base station dynamically determines the AL, and correspondingly, the terminal blindly detects multiple ALs to determine the AL currently used by the PDCCH. Furthermore, the base station can be configured with multiple CORESET & Search spaces (SS), each with different QCL or TCI parameters for its CORESET. The base station can dynamically select a search space that best matches the current channel spatial characteristics for transmission. Correspondingly, the terminal can blindly detect multiple SSs.

[0053] The following example, using a low-power wake-up signal (LP-WUS) as the first signal, further explains the technical problem to be solved by this application.

[0054] In related technologies, network-side devices can configure LP-WUS parameters themselves, such as frequency domain resources, time domain resources, Manchester coding, repetition count, and spatial characteristics. Currently, the protocol only considers the semi-static configuration of these parameters by the network-side device. However, semi-static configuration cannot be adjusted in a timely manner according to changes in the terminal's wireless communication environment, resulting in low resource efficiency. For example, configuring these resource transmission parameters according to relatively poor conditions leads to resource waste, or the semi-static configuration parameters do not match the dynamic channel environment, making it impossible to guarantee the quality of LP-WUS reception by the terminal.

[0055] To support adaptive adjustment of LP-WUS, existing methods such as PDSCH, PUSCH, or PUCCH are not suitable. This is because the adaptive adjustment of these channels is based on the DCI indication carried by the PDCCH. However, a key function of LP-WUS is that the UE does not need to constantly monitor the PDCCH; it only monitors the PDCCH after receiving LP-WUS. Therefore, relying on DCI indication for LP-WUS adaptive adjustment parameters is not feasible. Furthermore, using signaling carried by the channel to indicate adaptive adjustment transmission parameters would result in wasted signaling overhead and resources.

[0056] To address this, this application provides a method for adaptively adjusting signal parameters suitable for LP-WUS. At least one of time resources, frequency domain resources, and spatial domain resources can be dynamically adjusted according to the UE's transmission environment.

[0057] Specifically, the transmission parameter determination method provided in this application embodiment involves a terminal determining the transmission parameters of a first signal based on first information. The first signal is either an uplink signal or a downlink signal. The first information includes at least one of the following: transmission parameters of a second signal (the last signal received by the terminal), transmission parameters of a third signal (the signal that triggered the terminal to transmit the first signal), measurement results obtained from a measurement reference signal, a candidate transmission parameter set, and transmission parameter information of the first signal reported by the terminal. In this solution, the terminal can obtain its current transmission environment based on the first information, thereby determining the transmission parameters of the first signal. The second signal, the third signal, and the measurement results obtained from the measurement reference signal can all be based on existing measurement or interaction information of the terminal, without the need for dedicated signaling to adjust the parameters of the first signal. This allows the terminal to determine the transmission parameters of the signal based on the current transmission environment while reducing signaling overhead. The candidate transmission parameter set is semi-statically configured, thus limiting the signaling overhead.

[0058] The following description, in conjunction with the accompanying drawings, details the transmission parameter determination method, terminal, and network-side device provided in this application through some embodiments and application scenarios.

[0059] The execution subject of the transmission parameter determination method provided in this embodiment can be a transmission parameter determination device, which can be a terminal, or a control module or processing module in the terminal, etc. The following uses a terminal as an example to illustrate the technical solution provided in this application embodiment.

[0060] This application provides a method for determining transmission parameters. Figure 2 shows a flowchart of a method for determining transmission parameters provided by this application, which can be applied to a terminal. As shown in Figure 2, the method for determining transmission parameters provided by this application may include the following step 201.

[0061] Step 201: The terminal determines the transmission parameters of the first signal based on the first information.

[0062] In some embodiments of this application, the first signal is either an uplink signal or a downlink signal.

[0063] In one example, when the first signal is an uplink signal, the first signal can be a probe reference signal, a demodulation reference signal, or a phase noise tracking reference signal, etc.

[0064] In another example, when the first signal is a downlink signal, the first signal can be a wake-up signal, a channel state information reference signal, a demodulation reference signal, a time-frequency tracking reference signal, or a phase noise tracking reference signal, etc.

[0065] For example, the above wake-up signal is used to wake up the terminal to monitor the PDCCH; or, to wake up the network.

[0066] It is understandable that the above "wake-up network" means that when the terminal is in an idle, inactive, or unconnected state, the terminal can wake up the corresponding network by receiving a wake-up signal, so that the terminal can access the network of different operators.

[0067] In some embodiments of this application, the first information mentioned above includes at least one of the following:

[0068] The transmission parameters of the second signal;

[0069] The transmission parameters of the third signal;

[0070] Measurement results obtained by measuring the reference signal;

[0071] Candidate transmission parameter set;

[0072] The transmission parameter information of the first signal.

[0073] In some embodiments of this application, the second signal mentioned above is the last signal received by the terminal.

[0074] For example, the second signal mentioned above is the last signal received by the terminal before a specific time point, or the second signal mentioned above is the last signal received by the terminal after a specific time point.

[0075] In some embodiments of this application, the aforementioned third signal is a signal that triggers the terminal to send or listen to the first signal.

[0076] In some embodiments of this application, the measurement results obtained from the above-mentioned measurement reference signal may or may not be reported to the network-side device.

[0077] In some embodiments of this application, the above-mentioned candidate transmission parameter set includes at least one set of signal transmission parameters.

[0078] In some embodiments of this application, the transmission parameter information of the first signal mentioned above may be the transmission parameters of the first signal that the terminal needs to report to the network-side device.

[0079] In some embodiments of this application, the above-mentioned transmission parameter information includes at least one of the following:

[0080] The first signal transmission parameter adjustment request

[0081] The transmission parameters of the first signal determined by the terminal.

[0082] The adjustment amount of the transmission parameters of the first signal.

[0083] In some embodiments of this application, the transmission parameters of the first signal include at least one of the following:

[0084] Time-domain resource parameters, frequency-domain resource parameters, spatial-domain resource parameters, coding parameters, information bit length parameters, and power parameters.

[0085] For example, the time-domain resource parameters mentioned above include at least one of the following:

[0086] The number of symbols occupied by the first signal in Orthogonal Frequency Division Multiplexing (OFDM);

[0087] The number of modulation symbols used;

[0088] Number of chips used;

[0089] The number of monitoring occupancy (MO) times.

[0090] The number M of second time units included in the first time unit.

[0091] The number of OOK chip symbols included in an OFDM symbol.

[0092] For example, the frequency domain resource parameters mentioned above include at least one of the following: the number of physical resource blocks (PRBs) occupied by the first signal, the number of subcarriers, and the frequency hopping parameters.

[0093] For example, the above airspace resource parameters include at least one of the following:

[0094] The first signal includes quasi-co-location (QCL), transmission configuration indicator (TCI), and sounding reference signal resource indicator (SRI).

[0095] For example, the above encoding parameters include at least one of the following: encoding type, such as one of the error control encoding techniques, Reed-muller (RM) code, number of repetitions, repetition factor, encoding rate, and rate matching rate.

[0096] In the transmission parameter determination method provided in this application embodiment, the terminal determines the transmission parameters of a first signal based on first information, where the first signal is an uplink signal or a downlink signal. The first information includes at least one of the following: transmission parameters of a second signal (the last signal received by the terminal), transmission parameters of a third signal (the signal that triggered the terminal to send or listen to the first signal), measurement results obtained from a measurement reference signal, a candidate transmission parameter set, and transmission parameter information of the first signal reported by the terminal. In this solution, the terminal can obtain its current transmission environment based on the first information, thereby determining the transmission parameters of the first signal. The second signal, the third signal, and the measurement results obtained from the measurement reference signal can all be based on existing measurement or interaction information of the terminal, without the need for signaling specifically used to adjust the parameters of the first signal. This allows the terminal to determine the transmission parameters of the signal based on the current transmission environment while reducing signaling overhead. The candidate transmission parameter set is semi-statically configured, therefore the signaling overhead is also limited.

[0097] Optionally, in some embodiments of this application, the terminal can learn about the current transmission environment of the terminal based on the different information contained in the first information, so as to determine the transmission parameters of the first signal.

[0098] The following describes in detail, with different embodiments, the process by which the terminal determines the transmission parameters of the first signal when the first information is different.

[0099] In a first possible embodiment, when the first information includes the transmission parameters of the second signal, the terminal learns the current transmission environment of the terminal based on the transmission parameters of the second signal, i.e., the last signal received by the terminal, so as to determine the transmission parameters of the corresponding first signal.

[0100] Specifically, in some embodiments of this application, the above step 201 "the terminal determines the transmission parameters of the first signal based on the first information" can be implemented by the following step 201a.

[0101] Step 201a: The terminal determines the transmission parameters corresponding to the transmission parameters of the second signal in the first mapping relationship as the transmission parameters of the first signal.

[0102] In some embodiments of this application, the first mapping relationship described above is used to represent the correspondence between the transmission parameters of the second signal and the transmission parameters of the first signal.

[0103] In some embodiments of this application, the first mapping relationship described above is agreed upon by the protocol or configured by the network-side device.

[0104] In some embodiments of this application, the first information mentioned above includes the transmission parameters of the second signal.

[0105] In some embodiments of this application, the transmission parameters of the second signal are the same as the transmission parameters of the second signal during the first transmission process.

[0106] For example, the second signal in the first transmission process described above includes at least one of the following: an uplink signal in the radio link recovery process, an uplink signal in the random access process, PUCCH, PUSCH, and a Sounding Reference Signal (SRS).

[0107] In some embodiments of this application, the transmission parameters of the second signal include at least one of the following: number of repetitions, spatial characteristic parameters, PUCCH format, and PRACH format.

[0108] In one example, when the second signal is a PDCCH, the transmission parameters of the second signal include at least one of the following: the aggregation level of the PDCCH, the spatial characteristics parameters of the PDCCH, the repetition transmission parameters of the PDCCH, the search space type of the PDCCH, and the control resource set (CORESET) type of the PDCCH.

[0109] In another example, when the second signal is a PDSCH, the transmission parameters of the second signal include at least one of the following: the modulation and coding scheme (MCS) of the PDSCH, the spatial characteristic parameters of the PDSCH, and the repetition transmission parameters of the PDSCH.

[0110] Example 1: Taking the terminal as an example, the transmission parameters of LP-WUS, i.e. the first signal mentioned above, are determined based on the aggregation level (AL) of the last received PDCCH.

[0111] Scenario 1: The terminal can determine the LP-WUS transmission parameters based on the mapping relationship between the PDCCH AL and the LP-WUS transmission parameters. For example, if PDCCH AL = 1 & 2, the corresponding LP-WUS transmission count is 1, meaning there is no repetition. When PDCCH AL > 2, the corresponding LP-WUS transmission count is 2, meaning the repetition factor is 2. Alternatively, when PDCCH AL = 1 & 2, it corresponds to set 1 of LP-WUS transmission counts, such as LP-WUS transmission count = 1; when PDCCH AL > 2, it corresponds to set 2 of LP-WUS transmission counts, such as LP-WUS transmission count = 1 or 2.

[0112] It should be noted that when the PDCCH AL is greater than a specific value, the terminal can exit LP-WUS reception and start monitoring the PDCCH, or the terminal can continue monitoring the PDCCH without entering LP-WUS reception in order to obtain the corresponding transmission parameters from the signaling.

[0113] Scenario 2: The terminal can determine the spatial characteristics of LP-WUS based on the spatial characteristics of PDCCH. For example, if the UE assumes that the TCI of LP-WUS is the same as the TCI of the detected PDCCH, it can determine the transmission parameters of LP-WUS based on the detected TCI.

[0114] Case 3: The PDCCH mentioned above is a PDCCH in the terminal's specific search space or in CORESET.

[0115] For example, the PDCCH is a PDCCH within the terminal's specific search space, such as the UE-specific search space. Typically, a broadcast PDCCH in the common search space needs to consider the channel conditions of multiple terminals. A PDCCH in the terminal-specific search space primarily considers the channel conditions of a single UE, thus providing a better reference for the LP-WUS transmission parameters of that terminal. Alternatively, it could be a PDCCH in the CSS, but this PDCCH is UE-specific.

[0116] According to another example, if an LP-WUS is a terminal group's LP-WUS, then the PDCCH is a common search space PDCCH, such as type-3 common search space. This is because the parameters of this LP-WUS also need to consider the channel states of multiple UEs. In this case, the type of PDCCH used by the terminal as a reference for the LP-WUS transmission parameters is predefined by the protocol, such as depending on the type of LP-WUS—whether it is connected, idle, intrinsic, or configured on the network side—to determine the LP-WUS transmission parameters.

[0117] Thus, since the second signal is the last signal received by the terminal, the terminal can directly know the current transmission environment based on the transmission parameters of the second signal, and then determine the transmission parameters of the first signal based on the current transmission environment. At this time, the terminal does not need extra signaling overhead, thereby reducing the waste of resources.

[0118] In a second possible embodiment, where the first information includes the measurement result obtained from the measurement reference signal, the signal quality threshold or signal strength value included in the measurement report can reflect the current transmission environment of the terminal. Therefore, the value in the measurement report can determine the transmission parameters of the corresponding first signal.

[0119] Specifically, in some embodiments of this application, the above step 201 "the terminal determines the transmission parameters of the first signal based on the first information" can be implemented by the following step 201b.

[0120] Step 201b: The terminal determines the transmission parameters corresponding to the measurement results of the measurement reference signal in the second mapping relationship as the transmission parameters of the first signal.

[0121] In some embodiments of this application, the first mapping relationship described above is used to represent the correspondence between the measurement result of the measurement reference signal and the transmission parameters of the first signal.

[0122] In some embodiments of this application, the second mapping relationship described above is agreed upon by the protocol or configured by the network-side device.

[0123] For example, the reference signal mentioned above includes at least one of the following: a synchronization signal block (SSB), a channel state information-reference signal (CSI-RS), a tracking reference signal (TRS), a demodulation reference signal (DMRS), a reference signal for radio resource management (RRM) measurement, a reference signal for radio link failure (RLF) measurement, a reference signal for beam failure (BF) measurement, a reference signal for channel state information (CSI) measurement, and a reference signal for mobility measurement.

[0124] For example, the measurement of the reference signal mentioned above includes at least one of the following: physical layer measurement, or higher layer measurement.

[0125] For example, the measurement of the reference signal mentioned above can be an L1 or L3 measurement.

[0126] For example, the measurement results of the reference signal used for Channel State Information (CSI) measurement include at least one of the following: Physical Layer Reference Signal Receiving Power (L1-RSRP), Physical Layer Signal to Interference plus Noise Ratio (L1-SINR), Channel State Information Reference Signal Resource Indicator (CSI-RS), Synchronous Broadcast Channel Block Resource Indicator (SS / PBCH Block Resource Indicator (SSBRI), Channel Quality Indication (CQI), Precoding Matrix Indicator (PMI), and Rank Indication (RI).

[0127] Example 2: Taking the terminal as an example to determine the transmission parameters of LP-WUS, i.e. the first signal mentioned above, based on the CSI measurement report.

[0128] Scenario 1: Taking L1-RSRP or L1-SINR in the CSI measurement report as an example, the values of L1-RSRP or L1-SINR can be divided into N levels, or compared with N thresholds. Among them, the levels or comparison results respectively correspond to different transmission parameters of LP-WUS. For example, when L1-RSRP or SINR is greater than or equal to the first threshold, the transmission count of LP-WUS = 1, that is, there is no repetition (repetition factor = 1), or it corresponds to the coding rate or rate matching rate R1. Or, when L1-RSRP or SINR is greater than or equal to the second threshold and less than the first threshold, the transmission count of LP-WUS = 2, that is, the repetition factor = 2, or it corresponds to one. Or the coding rate or rate matching rate R2, where R2 < R1. When L1-RSRP or SINR is greater than or equal to the first threshold, the set 1 of the transmission count of LP-WUS, for example, the transmission count = 1, that is, there is no repetition (repetition factor

[0129] = 1), or it corresponds to the coding rate or rate matching rate R1. Or, when L1-RSRP or SINR is greater than or equal to the second threshold and less than the first threshold, the set 2 of the transmission count of LP-WUS, for example, the transmission counts = 2 (repetition factor = 2) and the transmission count = 1, or it corresponds to the coding rates or rate matching rates R1 and R2.

[0130] Generally, the terminal determines the transmission parameters of LP-WUS according to the CSI report and receives LP-WUS according to the determined transmission parameters, with a certain processing delay. The base station side may also require a certain processing time. Therefore, the effective time can be specified. For example, the UE sends a CSI report in slot n, and the effective time of the transmission parameters of LP-WUS determined according to this CSI report is slot n + k.

[0131] Among them, k can be predefined by the protocol, or configured by the network side device, or related to the capability of the terminal, or related to the sub-carrier spacing (SCS), for example, the SCS of the PUSCH and PUCCH reporting CSI and / or the SCS of LP-WUS. Similarly, the method for determining the effective time also applies to the step of determining the transmission parameters of LP-WUS based on other rules in this embodiment.

[0132] It can be understood that when L1-RSRP or SINR is less than a specific threshold, the UE can exit the reception of LP-WUS and start monitoring the PDCCH to receive the signaling containing the transmission parameters from the PDCCH.

[0133] Scenario 2: Taking the CQI in the CSI report as an example, the CQI index can be divided into N levels, or compared with N thresholds. The levels or comparison results correspond to different LP-WUS transmission parameters. For example, if the CQI index is ≤ 7, then 7...<CQI index≤12,CQI index> 12, each corresponding to different LP-WUS transmission parameters. Or, different modulation schemes in CQI correspond to different LP-WUS transmission parameters.

[0134] Scenario 3: If the reported results also include spatial characteristic information, such as the terminal reporting L1-RSRPs and the corresponding SSB or CSI indexes for each RSRP, the terminal can determine the spatial characteristics of the LP-WUS based on these reports. For example, an LP-WUS and a reported SSB or CSI may satisfy a QCL relationship. The QCL relationship can be at least one of QCL types A, B, C, or D. The terminal can determine the corresponding LP-WUS transmission parameters based on the QCL relationship.

[0135] Scenario 3: The CSI measurement report mentioned above contains multiple measurement results.

[0136] For example, the terminal reports the best M L1-RSRPs (M>1) to the network-side device. The terminal selects one according to predefined rules or a custom selection to uniquely determine the LP-WUS transmission parameters. For instance, it can choose the value corresponding to the best channel condition, such as the largest L1-RSRP, or the value corresponding to the worst channel condition, such as the smallest L1-RSRP, to uniquely determine the LP-WUS parameters. Another example is that the terminal reports wideband CQI and subband CQI. The terminal determines the LP-WUS transmission parameters based on the wideband CQI, or based on the wideband CQI of the same carrier as the LP-WUS, or based on the CQI of the subband whose frequency domain resources overlap with the LP-WUS. Alternatively, the terminal can determine multiple candidate LP-WUS transmission parameters based on multiple results.

[0137] Understandably, if the LP-WUS transmission parameters determined by the terminal based on the CSI report are unique, the terminal can attempt to receive LP-WUS based on these uniquely determined parameters. If the LP-WUS transmission parameters determined by the terminal based on the CSI report are a set, the terminal can determine the LP-WUS transmission parameters through blind detection, as described in step 201d below, which will not be elaborated here.

[0138] Optionally, in some embodiments of this application, when the first information includes the measurement result obtained from the measurement reference signal, the transmission parameter determination method provided in the embodiments of this application further includes step 301.

[0139] Step 301: The terminal sends the measurement results to the network-side device.

[0140] In some embodiments of this application, the above measurement results are used to determine the transmission parameters of the first signal.

[0141] In some embodiments of this application, the above measurement results may be sent to the network-side device via signaling.

[0142] For example, the aforementioned signaling can be Downlink Control Information (DCI) signaling, or Medium Access Control Control Element (MAC CE) signaling, etc.

[0143] Thus, since the measurement results can serve as the measurement results for the reference signal, characterizing the terminal's transmission environment (e.g., signal quality thresholds or signal strength), the terminal can determine the current transmission environment based on the measurement results, thereby determining the transmission parameters of the first signal. Simultaneously, the measurement of the reference signal is a normal signal quality detection process for the terminal, thus eliminating the need for unnecessary signaling overhead and reducing resource waste.

[0144] In a third possible embodiment, when the first information includes a set of candidate transmission parameters, the network-side device sends multiple sets of transmission parameters to the terminal. The terminal determines the set of candidate transmission parameters based on these transmission parameters, and then determines the transmission parameters of the currently received or transmitted first signal by detecting the parameters contained in the set of candidate transmission parameters. In one case, if the set of candidate transmission parameters contains only one set of transmission parameters, then that set of transmission parameters is directly determined as the transmission parameters of the first signal.

[0145] Specifically, in some embodiments of this application, the above step 201 "the terminal determines the transmission parameters of the first signal based on the first information" can be implemented by the following step 201c.

[0146] Step 201c: The terminal receives the first signaling from the network-side device.

[0147] In some embodiments of this application, the first signaling described above is used to indicate at least one transmission parameter in the candidate transmission set.

[0148] In some embodiments of this application, the first signaling is carried by PDCCH or PDSCH.

[0149] For example, the first signaling mentioned above can be MAC CE signaling, DCI signaling, or RRC signaling. Other L1 signaling is also not excluded.

[0150] Optionally, in some embodiments of this application, when the first information includes a set of candidate transmission parameters and the set of candidate transmission parameters includes at least two first transmission parameters, the above step 201 can be specifically implemented by the following step 201d.

[0151] Step 201d: The terminal blindly detects at least two first transmission parameters to determine the transmission parameters of the first signal.

[0152] In some embodiments of this application, the terminal attempts to demodulate the first signal based on each first transmission parameter in the candidate transmission parameter set. If the first signal is successfully parsed based on a certain first transmission parameter, then that first transmission parameter is determined as the transmission parameter of the first signal.

[0153] Example 3: Taking the set of candidate transmission parameters for terminal blind detection as an example, determine the transmission parameters of LP-WUS, i.e., the first signal mentioned above.

[0154] If the network-side device is configured with a set of candidate transmission parameters for LP-WUS, for example, if the network-side device configures the repetition factor set as {1, 2, 4}, the terminal needs to blindly detect all configured repetition factors. Alternatively, if the network-side device is configured with a set of candidate transmission parameters for LP-WUS, for example, if the network-side device configures the repetition factor set as {1, 2, 4}, the terminal determines the applicable repetition factor set as a subset of the configured set based on the transmission parameters of the second signal or the measurement results of the measurement reference signal, for example, {2, 4}. Then, the terminal needs to blindly detect all repetition factors in this subset.

[0155] Optionally, in some embodiments of this application, the terminal determines the transmission parameters of the first signal by detecting the first signal on the MO. In this regard, the transmission parameter determination method provided in the embodiments of this application further includes step A1 or step A2.

[0156] Step A1: The terminal determines the number of MOs occupied based on the number of repetitions or the repetition factor.

[0157] Step A2: The terminal determines the number of repetitions or the repetition factor based on the number of MOs occupied.

[0158] For example, the terminal can determine the repetition factor based on the number R of MOs configured in the network-side device.

[0159] For example, the repetition factor is uniquely determined as R. That is, the terminal assumes that if the network-side device sends an LP-WUS (i.e., the first signal mentioned above), then the LP-WUS occupies R MOs. For example, the same information is sent in each MO, and it is sent R times. Alternatively, the repetition factor is a set, where each element in the set is less than or equal to R. For example, if the network-side device configures the number of MOs R = 4, the set of repetition factors is {1, 2, 4}. That is, the terminal assumes that if the network-side device sends an LP-WUS, one LP-WUS may occupy 1, 2, or 4 MOs. Alternatively, the network-side device can configure the repetition factor individually, and the configured repetition factor cannot exceed the configured number of MOs R. If no repetition factor is configured, then the repetition factor is considered to be R.

[0160] For example, the terminal determines the number R of MOs based on the configured repetition factor. For instance, if the network-side device configures a repetition factor of 4, the terminal can assume the number of MOs equals the repetition factor of 4. Alternatively, if the network-side device configures a set of repetition factors, the terminal can assume the number R of MOs equals the configured maximum repetition factor. Optionally, the terminal can listen to only a portion of the R MOs. For example, if the terminal successfully receives LP-WUS in the first MO, it can choose not to listen to the remaining R-1 MOs.

[0161] Optionally, in some embodiments of this application, the method for determining transmission parameters provided in the embodiments of this application further includes step A3 or step A4.

[0162] Step A3: The terminal maps the first signal starting from the first MO in the configured set of MOs.

[0163] Step A4: The terminal starts mapping from a specific MO in a set of configured MOs based on the number of repetitions or repetition factor of the first signal.

[0164] Optionally, in some embodiments of this application, the preamble in the first signal described above can be sent in a specific MO.

[0165] In some embodiments of this application, the preamble in the first signal described above can be transmitted in a specific MO, including any of the following:

[0166] Transmitted only in the first MO occupied by the first signal;

[0167] Transmitted only before the first MO occupied by the first signal;

[0168] Transmitted in each MO occupied by the first signal;

[0169] Transmitted before each MO occupied by the first signal.

[0170] It is understood that the first signal is only sent in the first MO occupied by the first signal as follows: the preamble in the first signal is sent in the first MO occupied by the first signal, and is not sent in other MOs occupied by the first signal, nor before the MO occupied by the first signal.

[0171] The first signal mentioned above is sent only before the first MO occupied by the first signal: the preamble in the first signal is sent before the first MO occupied by the first signal, and is not sent before other MOs occupied by the first signal, nor is it sent in the MOs occupied by the first signal.

[0172] For example, in an LP-WUS, i.e., the first signal mentioned above, if it includes a synchronization signal, such as a preamble, the preamble is sent only once and does not need to be repeated, while the payload is repeated. Alternatively, both the preamble and the payload are repeated.

[0173] For example, the preamble is sent only once and does not need to be repeated, and there is a one-to-one correspondence between the length of the preamble and the number of times the payload is repeated.

[0174] Example 4: Taking LP-WUS as the first signal as an example, this illustrates that the preamble in the first signal can be sent in a specific MO.

[0175] A repetition number of R i LP-WUS, limited to specific R i Transmission is performed in multiple MOs to reduce blind detection by the terminal. For example, if the network-side device is configured with R = 4 MOs, LP-WUS always starts transmitting from the first of these 4 MOs. For example, R... i The candidate transmission parameter set sums to 1, 2, and 4. Then LP-WUS represents the first MO for R. i =1, the first and second MOs for R i =2, and the 1st to 4th MOs for R i =4.

[0176] Or, R i =1 LP-WUS can be transmitted from any position among the 1st, 2nd, 3rd, and 4th MOs, R i =2 LP-WUS can occupy 2 MOs consecutively starting from either the 1st or 3rd MO, R i LP-WUS with m=4 can start transmitting from the first MO. This method offers better network flexibility compared to starting from the first MO, but increases terminal complexity. Taking formula (1) as an example, where m... (Ri) Let m be the number of candidates with a repetition factor of Ri. (Ri)This can be achieved through protocol predefinition or configuration on the network-side device. In this example, m (1) =4,m (2) =2,m (4) =1.

[0177] In some embodiments of this application, the first MO including preamble transmission is longer than the second MO not including preamble transmission.

[0178] Example 4: An LP-WUS, i.e., the relationship between multiple repeated transmissions of the first signal mentioned above and the MO.

[0179] Case 1: Multiple repeated transmissions of an LP-WUS are located in the same MO.

[0180] If the network-side device configures the MO length, the length cannot be less than the number of OFDM symbols required by LP-WUS for the maximum number of LP-WUS repetitions configured. Alternatively, if the network-side device does not configure the MO length, the terminal can determine it based on the number of LP-WUS repetitions.

[0181] For example, the network-side device is configured with a repetition factor set of {2, 4}. The terminal assumes that an LP-WUS repetition factor of 2 corresponds to one MO length, and a repetition factor of 4 corresponds to another MO length. Alternatively, the terminal determines the MO length based on the configured maximum repetition factor. An LP-WUS may only occupy a portion of the resources in the MO, for example, when the repetition factor is 2.

[0182] If the network-side device configures the interval between adjacent MOs and uses the end position of the previous MO as a reference point, then the end position of the previous MO is determined according to the length of the MO configured on the network side, or the length of the MO is determined by the number of OFDM symbols required by LP-WUS when the maximum number of repetitions of LP-WUS is configured on the network side.

[0183] For example, if the network-side device is configured with a repetition factor set of {2, 4}, then the ending position of the MO is determined according to the number of OFDM symbols required for a repetition factor of 4.

[0184] As shown in Figure 3, the network-side device configures the interval from the end of the first adjacent MO to the start of the second MO as P2. One LP-WUS can occupy part of the resources in an MO. For example, if the MO is configured with a repetition factor of 4, the network-side device can send an LP-WUS1 with a repetition factor less than 4. If the repetition factor is 2, then LP-WUS1 occupies part of the resources in the MO.

[0185] For example, a retransmission is invalid if at least a portion of its time or frequency domain resources collide with a specific resource. The specific resource is, for example, an uplink (UL) symbol in a Time Division Duplex (TDD) configuration, such as a UL symbol in a cell common TDD DL-UL configuration. Or, an SSB symbol, such as an SSB indicated in SIB1. Optionally, the invalid retransmission is discarded, as shown in (1) of Figure 4, or the retransmission continues in the next set of valid symbols, such as symbols that do not collide with the specific resource, as shown in (2) of Figure 4, or the symbols in the retransmission that overlap with the specific resource are punctured or rate-matched. For example, LP-WUS retransmissions 4 times, each retransmission occupying 10 OFDM symbols. Assume the starting point of MO is symbol 1 in time slot n. The resources for the four repeated transmissions are symbols 1-10 of time slot n, symbols 11-14 of time slot n, symbols 1-6 of time slot n+1, symbols 7-14 of time slot n+1, symbols 1-2 of time slot n+2, and symbols 3-12 of time slot n+2. Assuming that at least one OFDM symbol in the 10 OFDM symbols of the second repeated transmission is a TDD UL symbol, the second repeated transmission will not be transmitted in symbols 11-14 of time slot n and symbols 1-6 of time slot n+1, but will be postponed to symbols 7-14 of time slot n+1 and symbols 1-2 of time slot n+2. The third repeated transmission will be postponed to symbols 3-12 of time slot n+2, and the fourth repeated transmission will be postponed to symbols 13-14 of time slot n+2 and symbols 1-8 of time slot n+3, as shown in (2) of Figure 4. Alternatively, the second retransmission may not be transmitted in symbols 11-14 of time slot n and symbols 1-6 of time slot n+1. The third and fourth retransmissions may still be transmitted in symbols 7-14 of time slot n+1 and symbols 1-2 of time slot n+2, and symbols 3-12 of time slot n+2, respectively, as shown in Figure 4(1). Alternatively, assuming that symbols 11-14 of time slot n are TDD UL symbols, the second retransmission may start from symbol 1 of time slot n+1 and be transmitted in symbols 1-10. Subsequent retransmissions may follow the same pattern, as shown in Figure 4(3).

[0186] The above method can also be applied to the case where the repetition factor is 1, that is, when there is no repeated transmission.

[0187] Understandably, if the time resources for a retransmission exceed the resources of the MO in which the LP-WUS resides, the retransmission is discarded. For example, if the end position of the MO is the 14th OFDM symbol in slot n+2, although the 4th retransmission is postponed to symbols 13-14 in slot n+2 and symbols 1-8 in slot n+3, it will not be sent because it exceeds the end position of the MO. Alternatively, if the time resources for a retransmission overlap with the next MO, the retransmission is discarded.

[0188] In this way, LP-WUS performance can be guaranteed even when it collides with specific resources. Furthermore, the terminal can determine which resources can receive LP-WUS based on the above rules.

[0189] Case 2: Multiple repeated transmissions of an LP-WUS are located in different MOs.

[0190] When the repetition factor is R, an LP-WUS is located in R MOs, meaning there is one repeated transmission in one MO. These R MOs can be adjacent or non-adjacent MOs.

[0191] If a duplicate transmission or at least part of the time or frequency domain resources in an MO collides with a specific resource, then the duplicate transmission or the MO is invalid. The specific resource is, for example, an uplink symbol (UL) in a TDD configuration, such as the UL symbol in a cell common TDD DL-UL configuration. Or, an SSB symbol, such as the SSB indicated in SIB1. Optionally, this invalid duplicate transmission is discarded, as shown in (1) of Figure 5, assuming a set of MOs includes 4 MOs. If the repetition factor of LP-WUS is 4, then it is transmitted 3 times in MO1, MO3, and MO4, but not in MO1, and LP-WUS is not transmitted in this MO. Alternatively, this duplicate transmission continues in the next valid MO, where there are no symbols that collide with the specific resource in the valid MO, as shown in (2) of Figure 5, assuming the repetition factor of LP-WUS is 2, then it is transmitted 2 times in MO1 and MO3. Alternatively, the symbols that overlap with the specific resource in this duplicate transmission are punctured or rate-matched, that is, they are still transmitted in this MO, but not in the symbols that overlap with the specific resource, as shown in (3) of Figure 5.

[0192] The above method can also be applied to the case where the repetition factor is 1, that is, when there is no repeated transmission.

[0193] Optionally, if the time resources for a single retransmission exceed the resources of the MO group to which this LP-WUS belongs, the retransmission is discarded.

[0194] Optionally, if at least part of the time or frequency domain resources collide with a specific resource during the transmission of an LP-WUS (including cases where the repetition factor is 1 or greater than 1), then the LP-WUS is not transmitted, or the LP-WUS is postponed to the next valid MO or the next set of valid MOs.

[0195] In this way, LP-WUS performance can be guaranteed even when it collides with specific resources. Furthermore, the terminal can determine which resources can receive LP-WUS based on the above rules.

[0196] For example, each of the R MOs has the same length. For instance, the length is determined by the sum of the lengths of the payload portion and the preamble. If the preamble is sent only once in the first RO, and the payload portion is repeated in each RO, then in the 2nd through R MOs, LP-WUS only occupies a portion of the resources in the MO. Alternatively, the length is determined by the payload portion. The preamble is sent before the first MO.

[0197] Alternatively, the first MO in the R MOs can be longer, and the subsequent R-1 MOs can be of equal length and shorter than the first MO. For example, a preamble is only sent in the first MO and not in the other R-1 MOs. Therefore, the length of the first MO is set to be longer than the length of the other MOs.

[0198] As shown in Figure 6, the network-side device configures the interval of each MO (Multiple Interchange) starting point. Optionally, the interval within a group and the interval between groups can be configured separately, P1' and P2', or a single interval can be configured for both intra-group and inter-group use. Figure 6 uses the separate configuration of P1' and P2' as an example. The length of each MO can be equal or unequal. Figure 6 uses the example of the first MO in each group having a longer length and the other MOs having shorter lengths. One LP-WUS can occupy multiple MOs in a group, for example, if the repetition count is 4, it occupies 4 MOs. The information transmitted in each MO is the same.

[0199] This allows for more flexible support of sending preambles in one or more MOs.

[0200] This application provides a method for determining transmission parameters. Figure 7 shows a flowchart of a method for determining transmission parameters provided by this application, which can be applied to a terminal. As shown in Figure 7, the method for determining transmission parameters provided by this application may include the following step 401.

[0201] Step 401: The network-side device determines the transmission parameters of the first signal based on the first information.

[0202] In some embodiments of this application, the first signal is an uplink signal or a downlink signal;

[0203] In some embodiments of this application, the first information mentioned above includes at least one of the following:

[0204] The transmission parameters of the second signal;

[0205] The transmission parameters of the third signal;

[0206] The measurement results obtained by measuring the reference signal

[0207] Candidate transmission parameter set,

[0208] The transmission parameter information of the first signal.

[0209] In some embodiments of this application, the second signal is the last signal sent by the network-side device to the terminal.

[0210] In some embodiments of this application, the transmission parameter information of the first signal is the transmission parameter information of the first signal sent by the terminal and received by the network-side device.

[0211] In some embodiments of this application, the network-side device receives first information sent by the terminal and determines the transmission parameters of the first signal according to different mapping relationships.

[0212] It is understandable that the description of the first piece of information above is the same as that on the terminal side, and will not be repeated here.

[0213] In the transmission parameter determination method provided in this application embodiment, the network-side device determines the transmission parameters of a first signal based on first information, where the first signal is an uplink signal or a downlink signal. The first information includes at least one of the following: transmission parameters of a second signal, where the second signal is the last signal received by the terminal; transmission parameters of a third signal, where the third signal is the signal that triggered the terminal to transmit the first signal; measurement results obtained from a measurement reference signal; a candidate transmission parameter set; and transmission parameter information of the first signal reported by the terminal. In this solution, the network-side device can obtain the current transmission environment of the terminal based on the first information, and then determine the transmission parameters of the first signal based on the transmission environment. The second signal, the third signal, and the measurement results obtained from the measurement reference signal can all be based on existing measurement or interaction information of the terminal, without needing to specifically receive signaling for adjusting the parameters of the first signal. Furthermore, the candidate transmission parameter set is semi-statically configured and is also the signaling that is already present. Therefore, the network-side device can determine the transmission parameters of the signal based on the current transmission environment while reducing signaling overhead.

[0214] Optionally, in some embodiments of this application, step 401 above can be specifically implemented by step 401a below.

[0215] Step 401a: The network-side device determines the transmission parameters corresponding to the transmission parameters of the second signal in the first mapping relationship as the transmission parameters of the first signal.

[0216] In some embodiments of this application, the first mapping relationship described above is used to represent the correspondence between the transmission parameters of the second signal and the transmission parameters of the first signal.

[0217] In some embodiments of this application, the first mapping relationship described above is agreed upon by the protocol or configured by the network-side device.

[0218] Thus, since the second signal is the last signal received by the terminal, that is, the last second signal sent by the network-side device, the network-side device can determine the transmission parameters of the first signal based on the mapping relationship of the transmission parameters of the second signal. At this time, the network-side device does not need extra signaling overhead, thereby reducing the waste of resources.

[0219] Optionally, in some embodiments of this application, where the first information includes the measurement result of the measurement reference signal, the transmission parameter determination method provided in the embodiments of this application further includes step B1.

[0220] Step B1: The network-side device receives the measurement results reported by the terminal.

[0221] In some embodiments of this application, the above measurement results are used to determine the transmission parameters of the first signal.
