In the DRX mechanism, when at least one of the following techniques is applied, such as Physical Downlink Control Channel (PDCCH) skipping, search space group switching, and DRX start offset, part of the terminal's uplink transmission may be in the DRX sleep period. This will cause the terminal to be woken up during the sleep period, resulting in higher power consumption. Summary of the Invention

[0032] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0033] I. Extended Reality (XR) Business.

[0034] XR refers to all combinations of real and virtual environments and human-computer interactions created by computer technology and wearable devices. It includes representative forms such as Augmented Reality (AR), Mixed Reality (MR), and Virtual Reality (VR), as well as the interpolation regions between them. The levels of virtual worlds range from partial sensory input to fully immersive virtual reality. A key aspect of XR is the expansion of human experience, especially experiences related to presence (represented by VR) and cognitive acquisition (represented by AR).

[0035] II. Radio Resource Control (RRC) Connected State DRX.

[0036] The basic mechanism of DRX is to configure a DRX cycle for a UE in the RRC_CONNECTED state. The DRX cycle consists of "On Duration" and "Opportunity for DRX": during "On Duration," the UE listens to and receives the Physical downlink control channel (PDCCH), etc.; during "Opportunity for DRX," the UE does not listen to the PDCCH to save power. The On Duration period is considered the active time, or wake-up time, while the Opportunity for DRX period is outside the active time, or inactive time, also known as sleep time. Furthermore, the network-side equipment configures an inactivity timer. If a new PDCCH is received within the onduration period, the inactivity timer will be started or restarted to extend the UE's PDCCH listening time.

[0037] DRX configuration can bring energy savings, but it also increases packet transmission latency.

[0038] Optionally, in the XR service model, service packets arrive at equal intervals, and the intervals are small floating-point numbers (non-positive integers) (e.g., 60 FPS / 16.67). Furthermore, XR services have very high latency requirements, with the Packet Delay Budget (PDB) for air interface transmission required to be around 10ms / 20ms. However, current standards cannot be configured to perfectly match the DRX configuration to the packet arrival period. This mismatch can cause a severe misalignment between data packets and the DRX period, significantly increasing the likelihood that data packets will be dropped before completing transmission within the PDB.

[0039] III. DRX Timer and Period Configuration Parameters.

[0040] A DRX cycle equals the sum of the UE's wake-up time and sleep time. In LTE systems, the system can configure either a short DRX cycle or a long DRX cycle for the UE based on different service scenarios. For example, during Voice over Internet Protocol (VoIP) services, the voice codec typically sends a VoIP packet every 20ms, so a 20ms short DRX cycle can be configured. During longer silent periods in a voice call, a long DRX cycle can be configured. If both short and long cycles are configured simultaneously, and the DRX short cycle timer (drx-ShortCycleTimer) times out, the UE will enter a long DRX cycle. The drx-ShortCycleTimer will be activated after the DRX inactivity timer (drx-InactivityTimer) times out.

[0041] The DRX timer can include the following timers: DRX duration timer (drx-onDurationTimer), drx-InactivityTimer, downlink discontinuous receive retransmission timer (drx-RetransmissionTimerDL), downlink discontinuous receive HARQ round-trip timer (drx-HARQ-RTT-TimerDL), uplink discontinuous receive retransmission timer (drx-RetransmissionTimerUL), uplink discontinuous receive HARQ round-trip timer (drx-HARQ-RTT-TimerUL), and drx-ShortCycleTimer.

[0042] When DRX is configured, the aforementioned drx-onDurationTimer indicates the duration for which the corresponding Medium Access Control (MAC) listens to the PDCCH within a DRX cycle. Furthermore, drx-onDurationTimer is activated only once per DRX cycle.

[0043] The aforementioned `drx-InactivityTimer` indicates the duration for which the corresponding MAC address needs to listen to the PDCCH after receiving a PDCCH indicating a new transmission. This `drx-InactivityTimer` starts or restarts on the first symbol after the reception of the PDCCH indicating a new transmission has ended. When the corresponding MAC receives a DRX command or a long DRX command from the MAC control unit (Long DRXcommand MAC CE), the `drx-InactivityTimer` stops. When the `drx-InactivityTimer` times out, if the corresponding MAC address is configured for a short DRX cycle, it enters the short DRX cycle; otherwise, it enters the long DRX cycle.

[0044] The aforementioned drx-RetransmissionTimerDL is a parameter for each Hybrid Automatic Repeat Request (HARQ) procedure, representing the maximum duration for which the PDCCH needs to be monitored to receive a downlink retransmission. During the execution of this timer, the corresponding MAC listens to the PDCCH. This timer starts on the first symbol after the drx-HARQ-RTT-TimerDL times out. The drx-RetransmissionTimerDL stops when a PDCCH indicating downlink transmission is received. This retransmission timer represents the maximum number of PDCCH slots the UE needs to continuously monitor to receive the desired downlink retransmission data.

[0045] The aforementioned drx-HARQ-RTT-TimerDL is a parameter specific to each HARQ process, representing the minimum duration required to receive downlink allocations for retransmission. This drx-HARQ-RTT-TimerDL is started on the first symbol after the downlink HARQ feedback transmission concludes. During the execution of this drx-HARQ-RTT-TimerDL, the corresponding MAC does not listen to the PDCCH. When this drx-HARQ-RTT-TimerDL times out, the drx-RetransmissionTimerDL for the corresponding HARQ process is started.

[0046] The drx-RetransmissionTimerUL parameter mentioned above is for each HARQ procedure, representing the maximum duration required to receive an uplink grant for uplink retransmission. During the execution of this drx-RetransmissionTimerUL, the corresponding MAC listens for the PDCCH. This drx-RetransmissionTimerUL starts on the first symbol after the drx-HARQ-RTT-TimerUL times out. It stops when a PDCCH indicating uplink transmission is received.

[0047] The drx-HARQ-RTT-TimerUL parameter described above is for each HARQ process and represents the minimum duration required to receive the uplink grant for retransmission. During the execution of this drx-HARQ-RTT-TimerUL, the corresponding MAC does not listen to the PDCCH. This timer is started on the first symbol after the completion of the first repetition of the Physical Uplink Shared Channel (PUSCH) transmission for the corresponding HARQ. When this drx-HARQ-RTT-TimerUL times out, the drx-RetransmissionTimerUL for the HARQ process is started.

[0048] The duration of the aforementioned drx-ShortCycleTimer is an integer multiple of the short cycle. When drx-inactivityTimer times out or a DRX command is received, and the corresponding MAC address is configured with a short cycle, drx-ShortCycleTimer is started. When drx-ShortCycleTimer times out and the corresponding MAC address enters a long cycle, or when a LongDRX Command is received, drx-ShortCycleTimer is stopped, and the corresponding MAC address enters a long cycle.

[0049] The above-mentioned period configuration parameters include two parts: the first part is the Long DRX period size, and the second part is the DRX start offset (drx-StartOffset), which is used to define the subframe at which the long period DRX and the short period DRX begin; in some embodiments, the long and short period drx-startoffsets need to be the same.

[0050] IV. Solution for skipping PDCCH monitoring.

[0051] 1. PDCCH skipping is a method of energy saving that dynamically instructs the UE to skip PDCCH listening for a certain period of time through Downlink Control Information (DCI). For example, PDCCH skipping DCI can be used to instruct the UE to skip PDCCH listening for the next 4, 8, or 16 slots. Skipping listening means not listening. Since the UE has been instructed to skip listening, it can enter the corresponding sleep state during this period.

[0052] 2. Search space group switching, for example, switching between search space group 0 and search space group 1, wherein the search space in search space group 0 is characterized by a sparser PDCCH monitoring period, and the search space in search space group 1 is characterized by a denser PDCCH monitoring period.

[0053] Optionally, search space group 0: the search space associated with sparse PDCCH listening cycles. Switching to search space group 0 can reduce PDCCH listening, saving energy but increasing scheduling latency.

[0054] Search Space Group 1: The search space associated with dense PDCCH listening cycles. Switching to Search Space Group 1 can reduce scheduling latency, but it consumes more power.

[0055] 5. Scheduling request.

[0056] A scheduling request is a marker indicating that a terminal is requesting uplink resources from the uplink scheduler. The terminal sends scheduling requests on the PUCCH using pre-configured dedicated periodic Physical Uplink Control Channel (PUCCH) resources. Dedicated PUCCH scheduling request resources can be configured for the terminal; short periods support low-latency services, while long periods are used for low-overhead services. New Radio (NR) supports configuring multiple scheduling requests for a single terminal. For terminals without configured scheduling requests, resources must be requested through a random access mechanism.

[0057] Network-side equipment needs to allocate scheduling request resources to the terminal's logical channels and check for SR reports on the allocated scheduling request resources. The terminal's MAC layer can be configured with zero or one or more scheduling request configurations. Each scheduling request configuration corresponds to one scheduling request identifier element (SchedulingRequestId IE). Each scheduling request configuration can contain multiple PUCCH resources used for sending scheduling requests, which can span multiple Bandwidth Parts (BWPs) and multiple cells. A logical channel can be configured with at most one scheduling request PUCCH resource for one BWP. Each scheduling request configuration corresponds to one or more logical channels. Each logical channel can be mapped to a 0 or 1 SR configuration configured by RRC.

[0058] VI. Definitions of k0, k1 and k2.

[0059] k0 refers to the slot interval between the downlink scheduling DCI and its scheduled physical downlink shared channel (PDSCH).

[0060] k1 refers to the slot interval between the PDSCH and its Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) response.

[0061] k2 refers to the slot interval between the uplink scheduling DCI and its scheduled PUSCH.

[0062] Optionally, for PDSCH, the UE side has a clear HARQ feedback process to determine whether the received PDSCH is correct.

[0063] The uplink transmission processing method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0064] Please see Figure 2 , Figure 2 This is a flowchart of an uplink transmission processing method provided in an embodiment of this application, such as... Figure 2 As shown, it includes the following steps:

[0065] Step 201: If the first preset condition is met, the terminal performs the first operation;

[0066] The first operation includes at least one of the following: skipping the target uplink transmission and canceling the target timer, wherein the target timer is used to trigger a retransmission of the target uplink transmission; the first preset condition includes at least one of the following:

[0067] The terminal receives target indication information sent by the network-side device. The target indication information is used to indicate skipping uplink transmissions within a preset time period. The target uplink transmission is the uplink transmission within the preset time period.

[0068] The target uplink transmission occurs within the inactive time period of the discontinuous reception DRX cycle.

[0069] In this embodiment, the terminal can determine whether a first preset condition is met, and if the first preset condition is met, trigger the execution of a first operation. This first preset condition can be agreed upon by a protocol or configured by the network-side device, and is not further limited here.

[0070] Optionally, when the first condition includes the terminal receiving target indication information sent by the network-side device, since the network-side device skips uplink transmission within a preset time period by indicating that the uplink transmission is to be skipped, the terminal skips the target uplink transmission based on the target indication information, thereby reducing terminal power consumption. The terminal can also cancel the corresponding target timer to avoid triggering retransmission of the target uplink, thus reducing terminal power consumption. It should be understood that the preset time period can refer to a period after receiving the target indication information, and the preset time period is associated with the terminal's inactive time period. For example, it can include the terminal's inactive time period, or it can only include a portion of the inactive time period. This avoids the terminal needing to be woken up to perform uplink transmission when it is in a sleep state during the inactive time period, which would result in high power consumption.

[0071] The first condition includes the target uplink transmission being located within an inactive period of a discontinuous reception DRX cycle. In this case, if the terminal determines that the target uplink transmission is located within an inactive period of the DRX cycle, the terminal can skip the target uplink transmission, thereby avoiding waking up to perform the target uplink transmission during the inactive period, thus reducing terminal power consumption. The terminal can also cancel the corresponding target timer, thereby avoiding retransmission of the target uplink transmission and further reducing terminal power consumption.

[0072] It should be understood that skipping the target uplink transmission mentioned above can be interpreted as canceling the target uplink transmission, or in other words, not performing the target uplink transmission. This can also be called skipping the target uplink transmission or canceling the target uplink transmission. Canceling the target timer can be understood as not starting or activating the target timer.

[0073] In this embodiment, the terminal performs a first operation when a first preset condition is met. The first operation includes at least one of the following: skipping a target uplink transmission and canceling a target timer, where the target timer triggers a retransmission of the target uplink transmission. The first preset condition includes at least one of the following: the terminal receives target indication information from a network-side device, where the target indication information indicates skipping uplink transmissions within a preset time period, and the target uplink transmission is an uplink transmission within the preset time period; the target uplink transmission is located within an inactive time period of a non-continuous DRX reception cycle. This avoids the need for the terminal to be woken up and perform uplink transmission or retransmission during the DRX inactive time period. Therefore, this embodiment can reduce terminal power consumption.

[0074] Optionally, in some embodiments, the above-mentioned target uplink transmission includes at least one of the following:

[0075] Hybrid Automatic Repeat Request (HARQ) feedback;

[0076] Dynamically scheduled transmission of the Physical Uplink Shared Channel (PUSCH);

[0077] Physical uplink control channel (PUCCH) transmission;

[0078] The Sounding Reference Signal (SRS) is transmitted.

[0079] It should be understood that, in some embodiments, when the target uplink transmission includes HARQ feedback, the target timer includes at least one of a downlink discontinuous receive retransmission timer and a downlink discontinuous receive HARQ round-trip time timer.

[0080] In this embodiment of the application, when HARQ feedback is cancelled, at least one of the downlink discontinuous reception retransmission timer and the downlink discontinuous reception HARQ round-trip time timer can be cancelled, thereby avoiding triggering HARQ feedback retransmission.

[0081] Optionally, in some embodiments, when the target uplink transmission includes dynamically scheduled PUSCH, the terminal performing the first operation under the condition of satisfying a first preset condition includes at least one of the following:

[0082] If the first preset condition is met, skip the dynamically scheduled PUSCH transmission and cancel the target timer;

[0083] If the first preset condition is met, the dynamically scheduled PUSCH transmission is not skipped and the target timer is canceled;

[0084] The target timer includes at least one of an uplink discontinuous reception retransmission timer and an uplink discontinuous reception HARQ round-trip time timer.

[0085] In this embodiment, if a dynamically scheduled PUSCH transmission is canceled or skipped, the corresponding drx-RetransmissionTimerUL and / or drx-HARQ-RTT-TimerUL are also canceled. If the dynamically scheduled PUSCH transmission is not canceled or skipped, the corresponding drx-RetransmissionTimerUL and / or drx-HARQ-RTT-TimerUL can also be canceled. Because drx-RetransmissionTimerUL and / or drx-HARQ-RTT-TimerUL are canceled, retransmission of PUSCH transmissions can be avoided, thus reducing terminal power consumption.

[0086] Optionally, in some embodiments, the target indication information is a first downlink control information (DCI), wherein the first DCI satisfies any one of the following:

[0087] Carry PDCCH skip instruction;

[0088] Carries a search space group switching instruction;

[0089] Carries DRX initial offset adjustment indication;

[0090] Carrying first indication information, the first indication information includes first sub-indication information, which is specifically used to indicate whether to skip uplink transmissions within a preset time period.

[0091] In this embodiment of the application, when the terminal receives a first DCI carrying a PDCCH skip instruction, a search space group switching instruction, or a DRX start offset adjustment instruction, the terminal may be implicitly instructed to perform a first operation.

[0092] It should be understood that during XR service transmission, the starting subframe of the next DRX cycle duration can be adjusted using the aforementioned DRX start offset adjustment instruction. This allows for the configuration of a DRX setup that perfectly matches the arrival cycle of XR service packets, preventing severe misalignment between XR service packets and the DRX cycle, which could lead to packets being dropped before completing transmission within the PDB. Therefore, the reliability of XR service transmission can be improved.

[0093] When the terminal receives a first DCI carrying the aforementioned first indication information, it can display an indication of whether to perform the first operation through the first sub-indication information in the first indication information. The first DCI carrying the aforementioned first indication information can be a DCI of an existing format or a DCI of a defined new format, without further limitation here.

[0094] Furthermore, in some embodiments, the first indication information further includes at least one of the following:

[0095] The second sub-indication information is used to indicate the skipped target uplink transmission;

[0096] The third sub-indication information is used to indicate the effective time information, and the preset time period includes the effective time period corresponding to the effective time information.

[0097] In this embodiment of the application, the aforementioned second sub-indication information is specifically used to indicate skipping a specified target uplink transmission. For example, indication 0 can indicate that the skipped target uplink transmission is a HARQ feedback transmission; indication 1 can indicate that the skipped target uplink transmission is a dynamically scheduled PUSCH transmission; indication 2 can indicate that the skipped target uplink transmission is a PUCCH transmission; and indication 3 can indicate that the skipped target uplink transmission is an SRS transmission. Of course, a single value can also indicate that the skipped target uplink transmission is one of two or more uplink transmissions, and no further limitations are made here.

[0098] The aforementioned effective time period can be either the aforementioned preset time period or a portion of the aforementioned preset time period. If the effective time period is the aforementioned preset time period, then when the terminal receives the first DCI, it determines to skip uplink transmissions within the effective time period based on the first indication information.

[0099] It should be noted that the rules for determining whether to skip a transmission differ depending on the type of uplink transmission. Optionally, in some embodiments, skipping the target uplink transmission includes: skipping the target uplink transmission according to a preset rule;

[0100] The preset rules include at least one of the following:

[0101] The first sub-rule is used to determine whether to skip HARQ feedback;

[0102] The second sub-rule is used to determine whether to skip dynamically scheduled PUSCH transmissions.

[0103] Skip the first PUCCH transmission, which is used for periodic or semi-persistent channel state information (CSI) reporting;

[0104] Skip periodic or semi-continuous SRS transmissions.

[0105] It should be understood that in the embodiments of this application, when the first preset condition includes the terminal receiving target indication information sent by the network-side device, and the first indication information carried by the target indication information includes third sub-indication information, the determination of whether to skip the target uplink transmission can be skipped without following the preset rules, and the target uplink transmission can be skipped directly.

[0106] Optionally, in some embodiments, the first sub-rule includes any of the following:

[0107] Rule 1: Skip all HARQ feedback within the preset time period;

[0108] Rule 2: If all N1 first HARQs are positive ACKs, skip the feedback of the N1 first HARQs. N1 is a positive integer. The N1 first HARQs are all the HARQs to be transmitted in a time unit within the preset time period, or the N1 first HARQs are the HARQs corresponding to a HARQ codebook within the preset time period.

[0109] Rule 3: If at least one of the N2 second HARQs is a negative acknowledgment (NACK), the feedback of the N2 second HARQs shall not be skipped. N2 is a positive integer. The N2 second HARQs are all the HARQs to be transmitted within a time unit of the preset time period, or the N2 second HARQs are the HARQs corresponding to a HARQ codebook within the preset time period.

[0110] Rule 4: If at least one of the N3 third HARQs is NACK, only NACK feedback is performed. N3 is a positive integer. The N3 third HARQs are all the HARQs to be transmitted within a time unit of the preset time period, or the N3 third HARQs are the HARQs corresponding to a HARQ codebook within the preset time period.

[0111] Rule 1 can be understood as follows: as long as there is HARQ feedback within a certain period of time (preset time period), HARQ feedback is required or skipped.

[0112] Rule 2 can be understood as follows: if all HARQ feedbacks to be transmitted in the same time unit or the same HARQ codebook are ACKs, then all HARQ feedbacks in that time unit are canceled or skipped.

[0113] Rule 3 can be understood as follows: if at least one of the HARQ feedbacks to be transmitted in the same time unit or the same HARQ codebook is NACK, then the HARQ feedback at that moment is not canceled or skipped.

[0114] Rule 4 can be understood as follows: if at least one of the HARQ feedbacks to be transmitted in the same time unit or the same HARQ codebook is NACK, then only NACK feedback will be transmitted at that time.

[0115] In this embodiment, the definition of the time unit can be set according to actual needs. For example, in some embodiments, the time unit can be a time slot. Optionally, if HARQ feedback is canceled or skipped in a subsequent period, the corresponding drx-RetransmissionTimerDL and / or drx-HARQ-RTT-TimerDL are also canceled.

[0116] Optionally, in some embodiments, the second sub-rule includes at least one of the following:

[0117] If the priority of the data sent by the first PUSCH in the dynamic scheduling is lower than the preset priority, the first PUSCH transmission is skipped.

[0118] If the logical channel type carried by the dynamically scheduled second PUSCH belongs to a preset type, the transmission of the second PUSCH is skipped.

[0119] If the Quality of Service (QoS) characteristics corresponding to the dynamically scheduled third PUSCH meet the second preset condition, the transmission of the third PUSCH is skipped.

[0120] In this embodiment, the priority of the data transmitted by the first PUSCH can be understood as logical channel priority or physical layer priority. Optionally, low-priority PUSCHs can be canceled or skipped, while high-priority PUSCHs cannot be canceled or skipped. For example, different priorities can be set for data in the base layer and enhancement layer. Assuming that the transmission of base layer data is of high priority and the transmission of enhancement layer data is of low priority, only base layer data can be transmitted.

[0121] Optionally, different priorities can be set for data within the field of view (FOV) and data outside the field of view (non-FOV). Assuming that transmitting data within the field of view has a high priority and transmitting data outside the field of view has a low priority, then only data within the field of view can be transmitted.

[0122] The QoS mentioned above can be explained using latency requirements as an example. PUSCHs with low latency requirements can be canceled or skipped, while PUSCHs with high latency requirements cannot be canceled or skipped. If the PUSCH transmission involves data multiplexing between logical channels, the latency requirement of the logical channel with the most urgent latency among the multiplexed logical channels can be considered.

[0123] Optionally, in some embodiments, the preset time period includes at least one of the following:

[0124] Skip the PDCCH listening time period;

[0125] The inactive period of the DRX cycle;

[0126] The first symbol is the last symbol of the first PDCCH or the last symbol of the time slot in which the first PDCCH is located. The first PDCCH is used to carry the first DCI. The first DCI is the target indication information. The first time is the start time of the next DRX cycle, or the first time is located before the start time of the next DRX cycle and is spaced apart from the start time of the next DRX cycle by a first preset time.

[0127] Skip the start time of the PDCCH monitoring period to the second time, where the second time is the start time of the next DRX cycle, or the second time is before the start time of the next DRX cycle and is spaced apart from the start time of the next DRX cycle by a second preset time.

[0128] The search space group switching completion time is the third time, where the third time is the start time of the next DRX cycle, or the third time is located before the start time of the next DRX cycle and is spaced apart from the start time of the next DRX cycle by a third preset time.

[0129] The end time of the second symbol to the fourth time, the second symbol is the last symbol of the second PDCCH or the last symbol of the time slot in which the second PDCCH is located, the fourth time is the start time of the next DRX cycle, or the fourth time is before the start time of the next DRX cycle and is spaced four preset times apart from the start time of the next DRX cycle, the second PDCCH is used to carry the DCI indicating the DRX start offset adjustment;

[0130] The effective time period corresponding to the effective time information indicated by the third sub-indication information is included in the first indication information carried by the first DCI. The first indication information also includes the first sub-indication information, which is specifically used to indicate whether to skip uplink transmission within a preset time period.

[0131] To better understand this application, the implementation of this application will be described in detail below through some specific embodiments.

[0132] Example 1: Once the terminal receives the first DCI, the effective time for subsequent cancellation or skipping of HARQ feedback and other transmissions is from the moment the first DCI is received until the start of the next DRX cycle. The moment the first DCI is received falls within the DRX active time, meaning that HARQ feedback and other transmissions can be skipped within the active time.

[0133] Upon receiving the first DCI indicating PDCCH skipping, search space group switching, or DRX start offset adjustment within the on-duration or inactivity timer, the terminal immediately cancels or skips HARQ feedback, PUSCH transmission, PUCCH transmission, or SRS transmission based on the following first rule until the start of the next DRX cycle. The first rule is as follows:

[0134] If all HARQ feedbacks to be transmitted in the same time unit are ACKs, then all HARQ feedbacks at that time are canceled or skipped.

[0135] If at least one of the HARQ feedbacks to be transmitted in the same time unit is NACK, then the HARQ feedback at that time is neither canceled nor skipped.

[0136] If at least one of the HARQ feedbacks to be transmitted in the same time unit is NACK, then only all NACK feedbacks are transmitted at that time.

[0137] Whether to cancel a PUSCH transmission depends on at least one of the following: the priority of the data transmitted, the type of logical channel it carries, and the logical channel priority. For example, only low-priority PUSCH transmissions can be canceled or skipped.

[0138] like Figure 3As shown, during the active period, PDSCH 1, PDCCH 1, and PDCCH 2 transmissions were performed. The terminal received the first DCI in PDCCH 1. At this time, the period from the end of the last symbol of PDCCH 1 carrying the first DCI to the start of the next DRX cycle is the time for canceling or skipping uplink transmission. If the HARQ feedback corresponding to PDSCH 1 is performed via PUSCH 1 within the time for canceling or skipping uplink transmission, then the PUSCH 1 transmission is canceled, that is, the HARQ feedback corresponding to PDSCH 1 is canceled, and PUSCH 2 transmission is performed during the duration of the next DRX cycle. This PUSCH 2 transmission can be understood as a retransmission of PUSCH 1, that is, re-performing the HARQ feedback. Furthermore, when the terminal receives the aforementioned first DCI in PDCCH 2, the time from the end of the last symbol of PDCCH 2 carrying the first DCI to the start of the next DRX cycle is the time for canceling or skipping uplink transmission. If the first DCI in PDCCH 2 schedules PUSCH 3 transmission, and the PUSCH 3 transmission is within the time for canceling or skipping uplink transmission, then the PUSCH 3 transmission is canceled, and PUSCH 4 transmission is performed within the duration of the next DRX cycle. The PUSCH 4 transmission can be understood as a retransmission of PUSCH 3.

[0139] Example 2: After the terminal receives the first DCI, the effective time for subsequent cancellation or skipping of HARQ feedback and other transmissions is from the start time of the DRX non-active time to the end time of the DRX non-active time.

[0140] like Figure 4 As shown, the only difference between this embodiment and Embodiment 1 is the start time of the cancellation or skipping of uplink transmission. After receiving the first DCI indicating PDCCH skipping, search space group switching, or DRX start offset adjustment within the on-duration or inactivity timer, the terminal cancels or skips HARQ feedback, PUSCH transmission, PUCCH transmission, or SRS transmission based on the first rule during the period from the start time to the end time of the DRX non-active time.

[0141] Example 3: The terminal cancels or skips HARQ feedback and other transmissions between the start time of skipping PDCCH listening and the start time of the next DRX cycle. The start time of skipping PDCCH listening may be within the DRX active time or within the non-active time.

[0142] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 lies only in the start time of canceling or skipping uplink transmission. When the terminal receives a DCI indicating PDCCH skipping within the on-duration or inactivity timer, it cancels or skips HARQ feedback, PUSCH transmission, PUCCH transmission, or SRS transmission based on the first rule during the period from the start time of skipping PDCCH listening to the start time of the next DRX cycle.

[0143] Example 4: The effective time for canceling or skipping HARQ feedback and other transmissions is the duration of skipping PDCCH listening, where the duration of skipping PDCCH listening is generally indicated by PDCCH skipping DCI.

[0144] like Figure 6 As shown, the difference between this embodiment and Embodiment 1 is only that the start and end times of canceling or skipping uplink transmission are different. In this embodiment, the first DCI indicates the duration of skipping PDCCH listening, and the duration of skipping PDCCH listening is the time of canceling or skipping uplink transmission.

[0145] Example 5: In the normal connected state of DRX (Connected DRX, CDRX), if there are transmissions such as HARQ feedback in the DRX non-active time, then the transmissions such as HARQ feedback are canceled or skipped.

[0146] For short-cycle services like XR (e.g., a cycle of 8.33ms), the following DRX configuration is used: DRXCycle = 8ms, on-duration = 2ms, inactivity timer = 1ms. This means that after receiving a PDCCH indicating a new transmission, the PDCCH needs to be listened to for 1ms.

[0147] For example, when the inactivity timer is less than k1, the HARQ feedback time corresponding to the latest PDSCH transmission of the terminal (the most recent uplink slot that can perform HARQ feedback) is already in the DRX sleep state, then the HARQ feedback is canceled or skipped based on the first rule mentioned above.

[0148] For example, when the inactivity timer is less than k2, the PUSCH transmission scheduled by DCI received by the terminal within the active time is in the DRX sleep state, then the PUSCH transmission is canceled or skipped based on the first rule mentioned above.

[0149] Optionally, the decision to cancel a PUSCH transmission can be based on the priority of the data transmitted or the logical channel type / logical channel priority. Only low-priority PUSCH transmissions can be canceled or skipped.

[0150] Example 6: When the terminal receives a DCI indicating PDCCH skipping, it cancels or skips the HARQ feedback and the corresponding drx-RetransmissionTimerDL and drx-HARQ-RTT-TimerDL during the duration of skipped PDCCH listening. Specifically, this includes the following scenarios:

[0151] Scenario 1: If it is an ACK, cancel the ACK transmission, and the network-side device assumes that the data reception is correct.

[0152] In scenario 2, if it is a NACK, the NACK transmission cannot be cancelled, but drx-RetransmissionTimerDL and drx-HARQ-RTT-TimerDL will still be cancelled, and the corresponding retransmission scheduling will be delayed until after the PDCCH skipping duration.

[0153] In scenario 3, if it is a NACK, the NACK transmission will still be cancelled, and drx-RetransmissionTimerDL and drx-HARQ-RTT-TimerDL will also be cancelled.

[0154] Example 7: When the terminal receives the first DCI indicating PDCCH skipping, it cancels or skips the PUSCH transmission during the duration of skipped PDCCH listening, as well as the corresponding drx-RetransmissionTimerUL and drx-HARQ-RTT-TimerUL.

[0155] Alternatively, the terminal receives the first DCI indicating PDCCH skipping and schedules PUSCH. After the UE transmits PUSCH, it performs PDCCH skipping, at which point the corresponding drx-RetransmissionTimerUL and drx-HARQ-RTT-TimerUL are canceled.
