[0002] In coverage enhancement technology research, the repetition transmission of the Physical Uplink Control Channel (PUCCH) should ensure consistent power and phase continuity as much as possible to achieve joint channel estimation and thus improve transmission performance. To maintain the continuity of power and phase during PUCCH repetition, changes in the Transmission Reception Point (TRP) are not expected during the repetition process. This can lead to PUCCH transmission failure when the transmission signal encounters obstacles.
[0003] As can be seen from the above, the PUCCH repetition transmission in coverage enhancement technology suffers from poor reliability. Summary of the Invention

Within the second time window, the terminal maintains a first transmission characteristic for repeated transmission of the target uplink channel. The first information includes power control information used for each target uplink channel transmission in the repeated transmission. The first time window is a normal time window configured by the network-side device. The first transmission characteristic is a transmission characteristic with consistent power and continuous phase. When the power control information used for PUCCH transmission in PUCCH repetition changes, the terminal can determine a second time window from within the first time window based on this change. For example, after the power control information changes, the second time window for continuous transmission according to the first transmission characteristic is restarted. This allows PUCCH repetition transmission to be adaptable to situations where the power control information used for PUCCH transmission changes. Furthermore, by changing the power control information, the reliability of PUCCH repetition transmission can be improved, and joint channel estimation can be fully utilized to effectively improve PUCCH repetition performance.

[0040] In related technologies, coverage enhancement techniques are used to ensure that PUCCH repetition transmission maintains power consistency and phase continuity as much as possible, thereby enabling joint channel estimation and improving transmission performance. To maintain power consistency and phase continuity in PUCCH repetition transmission, this coverage enhancement technique requires restricting the switching of power control parameters during PUCCH repetition transmission.
[0041] In this embodiment, the terminal can maintain consistent power and phase continuity during multiple PUCCH repetitions. When the network receives a PUCCH repetition, it can obtain channel information for the transmission of other PUCCH repetitions based on the demodulation reference signal (DMRS) of one of the PUCCHs. Then, it can use the DMRS of the multiple PUCCHs to perform joint channel estimation to improve reception performance. This technique is called joint channel estimation. The time interval in which joint channel estimation can be performed is called the time domain window.
[0042] Specifically, a time window can be defined as a time interval during which the terminal can perform phase-continuous transmission. Within this interval, the terminal will be subject to power and phase constraints to maintain power consistency and phase continuity in transmission.
[0043] For example: Figure 2 As shown, assume two consecutive uplink time slots are labeled ( Figure 2 The "U" in the text represents the uplink time slot, and Figure 2 In the context of the downlink time slot, "D" indicates that the uplink transmission within the two uplink time slots needs to maintain power consistency and phase continuity. Thus, the uplink transmission within these two uplink time slots can be considered to have relatively small channel variations, and demodulation can be performed through joint channel estimation at the base station side to improve performance.
[0044] In this embodiment, a second time window for continuous transmission can be determined based on the power control information of each PUCCH transmission during PUCCH repetition transmission. This allows the second time window for continuous transmission according to the first transmission characteristic to be restarted after the power control information changes during PUCCH repetition transmission. This makes PUCCH repetition transmission adaptable to situations where the power control information used for PUCCH transmission changes. Furthermore, the reliability of PUCCH repetition transmission can be improved by changing the power control information. In addition, joint channel estimation can be fully utilized to effectively improve PUCCH repetition performance.
[0045] It is worth noting that the target uplink channel repetition transmission in the embodiments of this application may also include Physical Uplink Shared Channel (PUSCH) repetition transmission. The PUSCH repetition transmission is similar to the PUCCH repetition transmission. For ease of explanation, the following embodiments only use PUCCH as an example for illustration, and do not constitute a specific limitation.
[0046] The method, apparatus, terminal, and readable storage medium for determining a time window provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0047] Please see Figure 3 The execution entity of the method for determining the time window provided in this application embodiment can be a terminal, such as... Figure 3 As shown, the method for determining the time window may include the following steps:
[0048] Step 301: The terminal determines a second time window within a first time window based on the first information; wherein, the terminal maintains a first transmission characteristic for repeated transmission of the target uplink channel within the second time window; the first information includes power control information used for each target uplink channel transmission in the repeated transmission of the target uplink channel; the first time window is a normal time window configured by the network-side device; the first transmission characteristic is a transmission characteristic with consistent power and continuous phase.
[0049] In practical implementation, the aforementioned first time window can be understood as: a normal time domain window configured by the network-side device. This means the network-side device configures the terminal to perform continuous transmission with consistent power and phase within the first time window. Alternatively, within the first time window, the network-side device expects the terminal to maintain power consistency and phase continuity between PUCCH transmissions according to power consistency and phase continuity requirements. For ease of explanation, the first time window will be referred to as the configuration time window in the following embodiments. In practical applications, some behaviors or indications that can break power consistency and phase continuity may occur; such behaviors or indications are called a target event. Thus, in the event of a target event, the terminal cannot continue continuous transmission according to the previous power control information.
[0050] Furthermore, the aforementioned second time window can be understood as the actual time window during which the terminal performs continuous transmission. For ease of explanation, the second time window will be referred to as the "actual time window" in the following embodiments. In implementation, the first time window may include one or at least two second time windows, and the terminal can resume continuous transmission according to different power control information within different second time windows. That is to say, after the terminal opens a second time window, it may terminate the second time window due to the occurrence of a target event, and a new second time window can be restarted subsequently.
[0051] It is worth noting that the first transmission characteristic mentioned above is similar to the continuous transmission characteristic of maintaining power consistency and phase continuity in PUCCH repetition transmission in the coverage enhancement technology. The difference is that within a first time window, there can be one or at least two second time windows, and different power transmission information can be used in different second time windows.
[0052] Furthermore, if the target uplink channel includes a PUCCH channel, the aforementioned power control information may include at least one of the following:
[0053] Closed-loop power control status value ClosedLoopIndex;
[0054] The power control status information index of the PUCCH channel is p0-PUCCH-Id;
[0055] The path loss reference signal index for the PUCCH channel is pucch-PathlossReferenceRS-Id.
[0056] Option 1: PUCCH-PathlossReferenceRS-Id
[0057] The primary function of this value is to indicate a mapping index value for a corresponding reference signal when calculating path loss. It indicates the index of PUCCH-PathlossReferenceRS in different power control parameters corresponding to different power control parameter sets (hereinafter referred to as: power control parameter sets). Using this index, the UE will determine the type of reference signal corresponding to the power control parameter set (e.g., Synchronization Signal and PBCH block (SSB) or Channel State Information Reference Signal (CSI-RS)), and the specific index information of the reference signal (e.g., SSB-Index or CSI-RI resource index). The UE will then use this information to reference the corresponding reference signal and calculate and estimate the downlink path loss value.
[0058] Option 2: p0-PUCCH-Id
[0059] The main function of this value is to indicate a mapping index value for finding the corresponding power control state parameter information when deciding which power control state to use. It indicates the corresponding index information of different closed-loop power control states (e.g., closedLoopIndex) for different power control parameter sets. Through this index, the terminal will determine whether the specific power control state corresponding to this spatial relationship is 0 or 1.
[0060] Option 3: ClosedLoopIndex
[0061] The main function of this value is to provide the corresponding power control status information. Under normal circumstances, when the PUCCH is configured with twoPUCCH-PC-AdjustmentStates and power control parameter set, there will be two power control states. Which power control state is used depends on the specific indication information in the power control parameter set.
[0062] It should be noted that the power control parameter sets of options one to three above may include a set of power control parameters of at least one of the above parameters, including but not limited to the spatial relationship parameter PUCCH-SpatialRelationInfo.
[0063] In practice, network-side devices can configure one, two, or all of the above three power control parameters for the terminal to trigger the terminal to determine the second time window through the power control parameters. No specific limitations are made here.
[0064] It should be noted that, in implementation, in addition to the power control information mentioned above, the first information may also include other information, such as configuration / indication information from the network-side device. That is, the network-side device can use semi-static configuration (e.g., semi-static uplink / downlink frame structure configuration, frequency hopping, etc.) and / or dynamic configuration or indication (e.g., events triggered by Medium Access Control (MAC) Control Element (CE) signaling or Downlink Control Information (DCI) signaling) to trigger the terminal to determine the second time window based on the event. No specific limitation is made here.
[0065] In applications, within the first time window, behaviors or indications that can disrupt power consistency and phase continuity may occur; such behaviors or indications are referred to as events. The terminal's handling behavior differs depending on the type of event. For example, for events triggered by semi-static configuration (such as semi-static uplink / downlink frame structure configuration, frequency hopping, etc.), it is assumed that the terminal must restart the second time window on the symbol of the first PUCCH transmission after the event. For events triggered by MAC CE or DCI, whether the terminal can restart the second time window depends on the terminal's capabilities.
[0066] As an optional implementation, the PUCCH repetition transmission includes a first PUCCH transmission and a second PUCCH transmission;
[0067] The terminal determines a second time window within a first time window based on the first information, including:
[0068] If the power control information corresponding to the first PUCCH transmission is different from the power control information corresponding to the second PUCCH transmission, the terminal determines that a target event has occurred, and the target event refers to the terminal's inability to maintain the first transmission feature.
[0069] Based on the occurrence of the target event, the terminal determines a second time window within the first time window.
[0070] In implementation, the first PUCCH transmission and the second PUCCH transmission can be two PUCCH transmissions that are temporally adjacent and executed by the terminal. For example, the terminal executes the first PUCCH transmission immediately after executing the second PUCCH transmission, or executes the second PUCCH transmission after a certain interval. Furthermore, the power control information corresponding to the first and second PUCCH transmissions is different; this can be understood as the power control information used by the terminal device when executing the first PUCCH transmission being different from the power control information used when executing the second PUCCH transmission.
[0071] In some embodiments, if the power control information corresponding to the first PUCCH transmission is different from the power control information corresponding to the second PUCCH transmission, the terminal can determine that a target event has occurred that cannot maintain the first transmission characteristic, and then the terminal can determine a second time window within a first time window based on the occurrence of the target event.
[0072] The terminal determines a second time window within a first time window based on the occurrence of the target event. This can be understood as: the terminal triggers the determination of a second time window within a first time window based on the occurrence of the target event, or the terminal can also determine the second time window based on the occurrence time of the target event.
[0073] The determination of a second time window within a first time window based on the occurrence time of the target event can be understood as follows: the current second time window terminates at the last symbol of the last PUCCH before the occurrence time of the target event, and / or a new second time window restarts at the first symbol of the first PUCCH after the occurrence time of the target event. In other words, the current second time window may include the time for executing the first PUCCH transmission, and the restarted new second time window may include the time for executing the second PUCCH transmission.
[0074] Optionally, the terminal determines a second time window within the first time window, including at least one of the following:
[0075] The terminal determines to close the second time window corresponding to the uplink channel transmission of the first target;
[0076] The terminal determines to open a second time window corresponding to the uplink channel transmission of the second target, or the terminal determines not to open a new second time window within the first time window.
[0077] Scenario 1
[0078] The terminal may close the second time window corresponding to the first target uplink channel transmission after performing the first target uplink channel transmission, or close the current second time window before performing the second PUCCH transmission, or close the current second time window immediately after performing the first PUCCH transmission. The second time window corresponding to the first target uplink channel transmission can be understood as: within the second time window, continuous transmission with consistent power and continuous phase is performed on at least one uplink channel transmission, including the first target uplink channel transmission.
[0079] In this case, it can avoid the situation where the second PUCCH is transmitted according to the power and phase used by the first PUCCH when encountering problems such as obstruction, which would result in low transmission performance or even transmission failure of the second PUCCH. In other words, it can improve the reliability of the second PUCCH transmission.
[0080] Scenario 2
[0081] The terminal can close the second time window corresponding to the first target uplink channel transmission and then open the second time window corresponding to the second target uplink channel transmission. That is, after terminating continuous transmission according to the first transmission characteristics, it can resume continuous transmission according to the power control information after the target event. The second time window corresponding to the second target uplink channel transmission can be understood as: within the second time window, continuous transmission with consistent power and continuous phase is performed on at least one uplink channel transmission, including the second target uplink channel transmission.
[0082] For example: Figure 4 or Figure 5 As shown, after terminating actual time window 1, the terminal device can restart actual time window 2, and even after terminating actual time window 2, it can restart actual time window 3, and so on, until the first time window terminates or the PUCCH is transmitted to the last symbol of the last PUCCH.
[0083] In this case, by closing the second time window corresponding to the uplink channel transmission of the first target and opening the second time window corresponding to the uplink channel transmission of the second target, continuous transmission can be resumed according to the power control information of the second PUCCH after the continuous transmission is terminated. This allows the second PUCCH transmission and other PUCCH transmissions in the new second time window to apply joint channel estimation to improve transmission performance.
[0084] Scenario 3
[0085] The terminal may not open a new second time window after closing the second time window corresponding to the uplink channel transmission of the first target. That is, after terminating continuous transmission according to the first transmission characteristics, it may not resume continuous transmission according to the power control information after the target event.
[0086] For example: Figure 6 As shown, after the terminal device terminates actual time window 1, it will not start a new actual time window until the first time window terminates.
[0087] In this case, after closing the current second time window, the terminal will not open a new second time window, and can give up subsequent continuous transmission to reduce the overhead and resource consumption of continuous transmission-related signaling.
[0088] In practice, whether a terminal can restart a new actual time window after terminating the actual time window can be determined by referring to the terminal's capability information and / or the type of the target event.
[0089] As an optional implementation, the terminal determines to open a second time window corresponding to the uplink channel transmission of the second target, or the terminal determines not to open a new second time window within the first time window, including:
[0090] If the terminal's capability information supports opening a new time window and / or the terminal receives a first Radio Resource Control (RRC) signaling, the terminal closes the second time window corresponding to the first target uplink channel transmission, and opens a new second time window at the first symbol position of the first target uplink channel transmission after the occurrence of the target event. The first RRC signaling is used to enable the terminal to reopen a new time window; or...
[0091] If the terminal's capability information does not support opening a new time window and / or the terminal receives a second RRC signaling, the terminal closes the second time window corresponding to the first target uplink channel transmission, and does not open a new second time window within the first time window. The second RRC signaling is used to prevent the terminal from reopening a new time window; or...
[0092] The terminal closes the second time window corresponding to the uplink channel transmission of the first target, and opens a new second time window at the first symbol position of the first uplink channel transmission after the occurrence of the target event; or...
[0093] The terminal closes the second time window corresponding to the uplink channel transmission of the first target, and does not open a new second time window within the first time window.
[0094] Implementation Method 1
[0095] If the terminal's capability information supports opening a new time window and / or the terminal receives the first signaling, the terminal closes the second time window corresponding to the first target uplink channel transmission, and opens a new second time window at the first symbol position of the first target uplink channel transmission after the occurrence of the target event. The first signaling is used to enable the terminal to reopen a new time window.
[0096] In implementation, the terminal can report its capability information to the network-side device. For example, the capability information includes the maximum duration for which the terminal can maintain power consistency and phase continuity according to power consistency and phase continuity requirements. In this way, the network-side device can determine whether the terminal supports opening a new time window based on the terminal's capability information, and then perform PUCCH-related configurations based on the determination result to enable or disable the terminal from reopening a new time window.
[0097] For example, if the terminal capability supports restarting the time window, the network-side device enables the terminal to reopen a new time window after closing the previous time window through the first signaling (such as: PUCCH restart time window signaling (PUCCH-Window-Restart)). The first signaling can be RRC signaling, or it can be other types of signaling, such as: Media Access Control Unit (MAC) CE signaling or Downlink Control Information (DCI) signaling, etc., without specific limitations here.
[0098] Of course, in specific implementation, the network-side device can also determine whether to enable or disable the terminal to reopen a new time window based on other information besides the capability information reported by the terminal; or, the network-side device can obtain the terminal's capability information through other means and determine whether to enable or disable the terminal to reopen a new time window based on the terminal's capability information; or, if the terminal determines that its own capability information supports opening a new time window, it can directly restart a new second time window after closing the current second time window.
[0099] In this embodiment, the target event can be a dynamically triggered event (e.g., triggered by MAC CE signaling or DCI signaling sent by the network-side device). Whether the terminal can restart the second time window after terminating continuous transmission based on the dynamic event depends on the terminal's capability. That is, if the terminal supports opening a new time window, the network side can enable the terminal to open a new second time window at the first symbol position of the first target uplink channel transmission after closing the current second time window.
[0100] Implementation Method 2
[0101] If the terminal's capability information does not support opening a new time window and / or the terminal receives a second RRC signaling, the terminal closes the second time window corresponding to the first target uplink channel transmission, and does not open a new second time window within the first time window. The second RRC signaling is used to prevent the terminal from reopening a new time window.
[0102] Corresponding to the first embodiment described above, in this embodiment, if the terminal does not support opening a new time window, the network side may not enable the terminal to open a new second time window after closing the current second time window.
[0103] Implementation Method 3
[0104] The terminal closes the second time window corresponding to the first target uplink channel transmission, and opens a new second time window at the first symbol position of the first target uplink channel transmission after the occurrence of the target event.
[0105] In this embodiment, the target event can be a semi-static event triggered by semi-static behavior (e.g., triggered by semi-static uplink / downlink frame structure configuration, frequency hopping, etc.). In this case, under the triggering of the semi-static event, after the terminal closes the second time window corresponding to the transmission of the first target uplink channel, it needs to open the second time window corresponding to the transmission of the second target uplink channel.
[0106] Implementation Method 4
[0107] The terminal closes the second time window corresponding to the uplink channel transmission of the first target, and does not open a new second time window within the first time window.
[0108] In this embodiment, when the terminal closes the current second time window, it directly abandons maintaining the first characteristic transmission, so that no new second time window is opened within the first time window. This can reduce the signaling overhead and resource consumption required to open a new second time window.
[0109] In some embodiments, before the terminal determines a second time window within the first time window based on the first information, the method further includes:
[0110] The terminal receives a third signaling message, which is used to configure or indicate target PUCCH resources and at least two power control information.
[0111] In specific implementation, the aforementioned third signaling may include at least one of the following: RRC signaling, Media Access Control Unit (MAC) CE signaling, and Downlink Control Information (DCI) signaling. Alternatively, the third signaling may also be other signaling from network-side devices, which are not specifically limited here.
[0112] For example, in FR2, when a PUCCH resource is activated, the identifier of the PUCCH resource (PUCCHresource ID) is determined. At the same time, the identifiers (IDs) of two spatial relation Infos can also be determined. Each spatial relation Info ID corresponds to a different set of beam and power control information.
[0113] Of course, for FR1, the way it configures or indicates the target PUCCH resource and at least two power control information is similar to the way it configures the target PUCCH resource and at least two power control information in FR2 above. The difference is that what is determined is not the ID of spatial Relation Info, but the identifier of power control information (such as the ID of Power ControlSetting), which will not be elaborated here.
[0114] In this embodiment, the network-side device can configure the terminal to perform PUCCH repetition transmission on the target PUCCH resource through a third signaling configuration. This PUCCH repetition transmission can use at least two power control information entries, where the first information entry includes the at least two power control information entries. In other words, different PUCCH transmissions within the PUCCH repetition transmission can use different power control information entries, thus enabling power control information switching during the PUCCH repetition transmission.
[0115] It is worth noting that the embodiments of this application differ from PUCCH repetition transmission in general coverage enhancement scenarios in that:
[0116] In typical coverage enhancement scenarios, the PUCCH repetition transmission power cannot be changed. The following formula is the PUCCH power calculation expression. The most likely way to change the power is by modifying δ in the formula through a group common Transmit Power Control (TPC) command. PUCCH,b,f,c The (i,l) term, while the remaining terms are pre-configured and will not change, but due to the existing conclusion that the TPC power accumulation command does not take effect within the time window, δ PUCCH,b,f,c (i,l) only changes after the time window ends. Therefore, in a typical coverage enhancement scenario, the PUCCH power cannot be changed within the time window of PUCCH repetition transmission.
[0117]
[0118] Among them, P PUCCH,b,f,c (i,q u ,q d ,l) represents: PUCCH transmission power, P CMAX,f,c (i) represents the maximum transmit power that the terminal can be configured with, P O_PUCCH,b,f,c (q u ) represents the sum of several basic transmit powers of the PUCCH, and μ represents the coefficient related to the subcarrier spacing (SCS). Representation: A parameter related to the number of resource blocks (RBs) occupied by PUCCH, PL b,f,c (q d () indicates: the estimated value of downlink road loss. Indicates: the power adjustment amount determined by different PUCCH formats, Δ TF,b,f,c (i) indicates: power adjustment based on the number of bits per unit PUCCH, specifically determined by the number of bits occupied per unit symbol or per unit bandwidth; g b,f,c (i,l) represents the power quantity under different power control states.
[0119] Specifically, the above g b,f,c (i,l) can be calculated using the following formula:
[0120]
[0121] Where l represents the power control state, δ PUCCH,b,f,c (i,l) represents the cumulative TPC power, m is an integer between 0 and i, and c(C i )-1 is used to characterize the base of the cumulative power value within the cell from the start of sending a PUCCH repetition power command value to the end of the transmission.
[0122] In this embodiment, since the corresponding PUCCH resource and its corresponding at least two power control information (i.e., at least two sets of power control parameters) are activated by the third signaling indication, or the specific power control information switching method can also be indicated by the first indication information, a switching of power control information will occur during the PUCCH repetition transmission corresponding to the PUCCH resource. Furthermore, each time the power control information is switched, PL... b,f,c (q dThe value of 'i' in the formula changes, causing a change in the overall PUCCH power value. This affects the behavior of joint channel estimation. Even if the same beam is used for transmission and the TPC command is not effective within the time window, the power consistency and phase continuity of PUCCH repetition will change. Therefore, in this case, it is necessary to adjust the terminal's windowing behavior based on this target event that breaks power consistency and phase continuity, such as closing the current second time window and reopening a new second time window.
[0123] Optionally, the method for determining the time window further includes:
[0124] The terminal receives the first instruction information;
[0125] The terminal determines the number of times N is repeated for the target uplink channel according to the first indication information, wherein the terminal changes the power control information once every N times it performs the target uplink channel transmission, and N is an integer greater than or equal to 1.
[0126] In implementation, the aforementioned first indication information is used to instruct the terminal to change the power control information once every N PUCCH transmissions during PUCCH repetition. This first indication information may be carried in the aforementioned third signaling, or it may also be carried in other signaling or messages different from the third signaling, without specific limitations here.
[0127] For example: Figure 4 As shown, the network-side device can configure the PUCCH repetition transmission to use power control information A and power control information B through the third signaling. In this case, if N equals 2, the terminal uses power control information A in the first and second PUCCH transmissions and uses power control information B in the third and fourth PUCCH transmissions.
[0128] For example: Figure 5 or Figure 6 As shown, the network-side device can configure the PUCCH repetition transmission to use power control information A and power control information B through the third signaling. In this case, if N equals 1, the terminal uses power control information A in the first PUCCH transmission, uses power control information B in the second PUCCH transmission, uses power control information A in the third PUCCH transmission, and so on.
[0129] In some embodiments, the first indication information includes a mapping pattern configured by the network-side device, wherein the mapping pattern corresponds one-to-one with the N.
[0130] In implementation, the mapping pattern can include a sequential mode and a cyclic mode. In the sequential mode, the mapping pattern changes every two transmissions. Therefore, the power control information corresponding to the mapping pattern also changes every two transmissions, i.e., N equals 2. For example: Figure 4 As shown, during PUCCH repetition transmission, the terminal changes the power control information once every two PUCCH transmissions.
[0131] Furthermore, in the cyclic mode, the mapping pattern changes with each transmission. Therefore, the power control information corresponding to the mapping pattern also changes with each transmission, meaning N equals 1. For example: Figure 5 or Figure 6 As shown, during PUCCH repetition transmission, the terminal changes the power control information once for each PUCCH transmission.
[0132] In other factual methods, the above mapping pattern may also correspond one-to-one with the power control information, and the power control information can also be controlled by changing the mapping pattern, which will not be elaborated here.
[0133] It should be noted that, in addition to indicating the switching mode of power control information through the first indication information mentioned above, the switching mode of at least two power control information indicated by the third signaling may also be determined through other methods that are pre-agreed by the protocol or the default switching mode, which are not specifically limited here.
[0134] It is worth noting that changes to power control information can be achieved through one or at least two of the following methods:
[0135] By modifying power control parameters, such as the closed-loop power control state value ClosedLoopIndex, the power control state information index p0-PUCCH-Id of the PUCCH channel, and the path loss reference signal index PUCCH-PathlossReferenceRS-Id of the PUCCH channel.
[0136] In this embodiment, the switching frequency of power control information can be adjusted by configuring a mapping pattern.
[0137] As an optional implementation method,
[0138] The terminal does not expect N to be equal to 1.
[0139] In implementation, the terminal does not expect N to be equal to 1. This can be understood as the terminal not expecting to change the power control information once for every PUCCH transmission during PUCCH repetition, but rather to change the power control information once for every at least two PUCCH transmissions.
[0140] In other words, compared to Figure 5 and Figure 6 The terminal prefers to follow the transmission method shown. Figure 4 The transmission method shown performs PUCCH repetition transmission, which can improve the gain of the actual time window.
[0141] It should be noted that, in practice, after the terminal determines that it does not expect N to be equal to 1, the terminal still switches the power control information according to the value of N in the first indication information of the network-side device. For example, if the terminal does not expect N to be equal to 1, but the first indication information sent by the network-side device to the terminal carries N equal to 1, the terminal will still change the power switching information once after each PUCCH transmission. Alternatively, the terminal can also report the expected information so that the network-side device can configure the value of N according to the terminal's expected information. No specific limitation is made here.
[0142] As an optional implementation, the terminal determines a second time window within a first time window based on the first information, including:
[0143] After enabling the terminal to open or restart the time window, if N equals 1, the terminal expects not to open a new second time window within the first time window.
[0144] After enabling the terminal to open or restart the time window, the terminal can open the first second time window by default and close the second time window based on the occurrence of the target event. In this embodiment, after the terminal closes the second time window, if N equals 1, the terminal expects not to open a new second time window within the first time window.
[0145] N equals 1, which can be understood as follows: every time the terminal performs a PUCCH transmission, it changes the power control information once. If a new second time window is opened at this time, the second time window can only last for the duration of one PUCCH transmission. This will cause unnecessary signaling overhead and resource consumption related to the terminal opening a new second time window.
[0146] In other words, when N equals 1, relative to... Figure 5The terminal prefers to follow the transmission method shown. Figure 6 The transmission method shown is used for PUCCH repetition transmission.
[0147] In this embodiment, when the terminal learns that N equals 1, the terminal will not reopen a new second time window, which can reduce signaling overhead and resource consumption.
[0148] It should be noted that in real-world applications, if a terminal does not expect to open a new second time window within the first time window, it may still reopen the second time window as needed, which does not constitute a specific limitation.
[0149] In this embodiment, the terminal determines a second time window within a first time window based on first information. Within the second time window, the terminal maintains a first transmission characteristic for repeated transmission of the target uplink channel. The first information includes power control information used for each target uplink channel transmission in the repeated transmission. The first time window is a normal time window configured by the network-side device. The first transmission characteristic is a transmission characteristic with consistent power and continuous phase. When the power control information used for PUCCH transmission in PUCCH repetition changes, the terminal can determine a second time window from within the first time window based on this change. For example, after the power control information changes, the second time window for continuous transmission according to the first transmission characteristic is restarted. This allows PUCCH repetition transmission to be adaptable to situations where the power control information used for PUCCH transmission changes. Furthermore, by changing the power control information, the reliability of PUCCH repetition transmission can be improved, and joint channel estimation can be fully utilized to effectively improve PUCCH repetition performance.
