Description

Technical Field

[0001] The present invention relates to wireless communication technology, and more specifically, to a wireless communication method and related equipment, such as a user equipment (UE) and a base station (BS), such as a gNB. Background Art

[0002] The wireless communication system of the third generation (3G) mobile phone standards and technologies is well known. Such 3G standards and technologies are developed by the Third Generation Partnership Project (3GPP). The third generation of wireless communication is developed to support macrocellular mobile phone communications, so that communication systems and networks are moving towards broadband and mobile systems. In a cellular wireless communication system, a user equipment (UE) is connected to a radio access network (RAN) via a wireless link. The RAN includes a group of base stations (BS) and an interface to the core network (CN), the former providing a wireless link with the UE in the base station coverage area, and the latter providing overall network control. The RAN and CN each perform their respective functions related to the entire network.

[0003] The 3rd Generation Partnership Project developed the Long-Term Evolution (LTE) system, the Evolved Universal Mobile Telecommunications System Radio Access Network (E-UTRAN), for mobile access networks, where one or more macro base stations are supported by base stations called eNodeB or eNB (evolved NodeB). LTE is further evolving towards the so-called 5G or New Radio (NR) system, where one or more cells are supported by base stations called Next Generation NodeB base stations (gNB).

[0004] The 5G wireless communication system is designed to provide enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC) and massive machine type communication (mMTC) services.

[0005] Extended Reality (XR) and cloud gaming services are important media applications supported by 5G. XR is a general term for different types of reality, referring to all real and virtual combined environments and human-computer interactions generated 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 areas inserted between them. A new research project description (SID) on XR evaluation has been approved, and the characteristics and challenges of XR traffic are summarized as follows:

[0006] High data rates with limited latency

[0007] For high-resolution 3D VR videos based on different frame rates, color codecs, bit depths, compression rates, etc., the transmission data rate can reach up to 60Mbps and above, with limited latency of about 10 to 30ms.

[0008] Non-integer cycles with jitter

[0009] The benchmark for downlink (DL) and uplink (UL) video streams has been determined to be 60 frames per second (fps), and 30fps, 90fps, and 120fps can be optionally evaluated. According to the formula for packet arrival time, the corresponding period is {33.33ms, 16.67ms, 11.11ms, 8.33ms}. In addition, XR traffic arrival also has jitter characteristics. According to the RAN1 protocol, the jitter of the traffic is modeled using a truncated Gaussian distribution, and its jitter range varies from [-4,4]ms (baseline) or [-5,5]ms (optional).

[0010] Different frame sizes

[0011] In the field of video compression, three main frame types are defined by three different video algorithms, which have the following characteristics:

[0012] -I frames are the least compressible and can be decoded independently

[0013] -P frames can use the previous frame for decompression and are more compressible than I frames.

[0014] -B frames can use the previous and forward frames to get the highest amount of data compression.

[0049] The embodiments of the present invention describe technical matters, structural features, implementation purposes and effects in detail with reference to the accompanying drawings. Specifically, the terms in the embodiments of the present invention are only used for the purpose of describing specific embodiments, rather than limiting the disclosure.

[0050] The following problems exist in business traffic, such as XR business transmission.

[0051] Discontinuous Reception (DRX) is one of the effective methods for user equipment (UE) to save power. When the UE enters the DRX-OFF state, it will suspend for physical downlink control channel (PDCCH) monitoring and can enter a dormant state to save UE power. As discussed in the RAN 1 meeting of Release 17, a truncated Gaussian distribution is used to model the jitter of DL and UL video streams for XR services. The jitter range is agreed to be [-4, 4] ms (baseline) and [-5, 5] ms (optional). This means that the XR packet may arrive at the gNB or UE within a time window of 8 ms or 10 ms, and the exact arrival time is not known in advance. When XR traffic arrives before discontinuous reception on (DRX-ON), the scheduling grant will be monitored in the DRX of the duration timer. However, when XR traffic arrives after DRX-ON, the UE needs to wait for the scheduling grant until the next DRX cycle. This will result in a large delay. Some enhancements should be considered to handle XR jitter for DRX.

[0052] DRX is one of the effective methods for UE power saving. When the UE enters the discontinuous reception off (DRX-OFF) state, the UE will suspend for PDCCH monitoring and can enter the sleep state to save UE power. In the current 3GPP specification, the UE needs to monitor PDSCH in the configured semi-persistent scheduling (SPS) opportunity, regardless of whether it is in DRX ON or OFF when DRX is configured. According to the discussion of the traffic model, the average packet size is very large. Taking AR / VR 60Mbps as an example, the average packet size is 125000 bytes. To transmit such a large transport block (TB), multiple time slots need to be used in the time domain. When DRX and / or SPS / configuration grant (CG) are configured, for packets arriving before SPS / CG, the SPS / CG transmission opportunity cannot fully transmit these packets. Then, if the UE waits for the scheduling grant until the next DRX on duration, this will also cause a large delay. Some enhanced methods are needed to solve this problem. In addition, the TB size of XR varies over time. If the SPS / CG resource configuration is conservative, a lot of resources and power will be wasted. On the contrary, when SPS / CG resources are fully configured, CG / SPS transmission opportunities may fail to fully transmit TBs. Some enhancement methods to handle these issues should be considered.

[0053] In Release 15 / 16 / 17, the UE needs to monitor the Physical Downlink Shared Channel (PDSCH) at the configured SPS opportunities, regardless of whether it is in DRX ON or OFF when DRX is configured. However, receiving PDSCH with a dynamic scheduling method when the UE is in active time has greater flexibility in resource allocation and hybrid automatic repeat request (HARQ) feedback. In addition, in some cases, when part of the CG / SPS overlaps with the DRX active time, the PDSCH received on the SPS or the Physical Uplink Shared Channel (PUSCH) transmitted on the CG will consume more energy. Therefore, a method to skip SPS / CG should be considered.

[0054] In Rel-15 / 16 / 17, physical downlink control channel (PDCCH) adaptation is indicated by scheduling downlink control information (DCI), which means that PDCCH adaptation can only be triggered by DCI scheduling PDSCH / PUSCH. However, PDCCH adaptation is not triggered when there is no data to be transmitted or received. In addition, in the current 3GPP specification, the radio resource control (RRC) value of the PDCCH skip duration can be indicated by DCI. However, in some cases, these values ​​(for example, the values ​​are too small or too large) cannot match well with XR services. Improvements to these issues should be considered.

[0055] The present invention can be summarized as follows:

[0056] 1. When XR traffic arrives before DRX-ON, the scheduling grant will be monitored in the DRX-ON duration timer. However, when XR traffic arrives after DRX-ON, the UE needs to wait for the scheduling grant until the next DRX cycle. This will cause a large delay. Some enhancements should be considered to handle XR jitter for CDRX. Method 1: Multiple values ​​of DRX-onDuration timer may be considered. Method 2: Configure a sliding DRX-onDurationtimer. A time offset set and a reference or default value of the DRX-onDurationtimer may be configured for the UE, where the time offset is used to indicate the start of the DRX-onDurationtimer and the reference or default value is used to determine the actual duration of the DRX-onDurationtimer. Method 3: Configure a larger value for DRX-onDurationtimer. This value can cover the jitter range and some parts of DRX-onDurationtimer can be skipped. Method 4: Configure multiple active DRX configurations (a set of active DRX configurations). A DRX configuration set includes one or more DRXs. Dynamic or semi-static methods can be used to activate and switch DRXs within the set. Method 5: Configure a negative integer group, wherein the negative integer group includes one or more values. Signaling may indicate a value in the set and modify the start of the next one or more DRX-onDuration timers.

[0057] 2. When DRX and SPS / CG are configured, the data packet arrives before SPS / CG, and the SPS / CG transmission opportunity cannot fully transmit the data packet, then if the UE waits for scheduling until the DRX on duration, it will cause a large delay. Some enhancement methods are needed to solve this problem. In addition, the TB size of XR varies over time, and when the SPS / CG resource configuration is conservative, a lot of resources and power will be wasted. Conversely, when the SPS / CG resource configuration is aggressive, the CG / SPS transmission opportunity cannot fully transmit the TB. Some enhancement methods to deal with these problems should be considered. Method 1: For CG, the default value of the additional DRX on-duration timer DRX-ondurationtimer can be configured. UCI signaling can be used to trigger the additional DRX on-duration timer DRX-ondurationtimer, where UCI is carried on the CG PUSCH. The additional DRX on-duration can be pre-configured through RRC signaling. Mode 2: For CG, a set of additional DRX on-duration timer DRX-ondurationtimer values ​​can be configured. UCI is used to indicate one of the values ​​of the set of additional DRX on-duration timer. The size of UCI is related to the size of the set of additional DRX on-duration timer. Each state of UCI can indicate a value in the set of additional DRX on-duration timer, where UCI is carried on CG PUSCH.

[0058] 3. In the current 3GPP specification, the UE needs to monitor PDSCH at the configured SPS opportunity, regardless of whether it is in DRX on or DRX off when DRX is configured. However, when the UE is in active time, receiving PDSCH with a dynamic scheduling method has greater flexibility in resource allocation and HARQ-ACK feedback. In some cases, when part of the CG / SPS overlaps with the DRX active time, the PDSCH received on the SPS or the PUSCH transmitted on the CG will consume more energy. Therefore, a method of skipping SPS / CG should be considered. ·Method 1: The default method can be used to indicate whether CG / SPS can be skipped during the DRX-onDuration timer, where skipping CG / SPS means that the UE does not send PUSCH or receive PDSCH on the corresponding CG / SPS configuration (when SPS is skipped, the HARQ feedback corresponding to SPS is also skipped). Method 2: A semi-static mechanism can be considered to introduce RRC signaling to indicate whether CG / SPS can be skipped during the DRX-onDuration timer. ·Method 3: Use scheduling DCI (e.g., UE-specific DCI) or non-scheduling DCI (e.g., group-common DCI) to indicate whether a CG / SPS or a group of CG / SPS or a part of CG / SPS can be skipped.

[0059] 4. In the current 3GPP specification, PDCCH adaptation is indicated by scheduling DCI, which means that PDCCH adaptation can only be triggered by DCI scheduling PDSCH / PUSCH. However, PDCCH adaptation will not be triggered when there is no data to transmit or receive. In addition, in the current 3GPP specification, the RRC value of the PDCCH skip duration can be indicated by DCI at most. However, in some cases, these values ​​cannot be well matched with XR services. For example, the values ​​are too small or too large. Some improvements to these issues should be considered. A non-scheduled DCI, used to indicate PDCCH adaptation. The size of the non-scheduled DCI is configurable. • Reuse the reserved field in the scheduling DCI to indicate PDCCH skipping. The reserved field can be redefined as the remaining PDCCHs skipped within a period of time. A set of PDCCH skip modes is configured for XR, and then either scheduled DCI or non-scheduled DCI can be used to indicate the set value.

[0060] Figure 1A communication network system 30 for an embodiment of the present invention is illustrated. In some embodiments, the communication network system 30 is used to provide wireless communication, which includes one or more user equipments (UEs) 10 and a base station (e.g., gNB or eNB) 20. One or more UEs 10 may include a memory 12, a transceiver 13, and a processor 11 coupled to the memory 12 and the transceiver 13. The base station 20 may include a memory 22, a transceiver 23, and a processor 21 coupled to the memory 22 and the transceiver 23. The processor 11 or 21 may be configured to implement the proposed functions, processes, and / or methods described in this description. The layers of the radio interface protocol may be implemented in the processor 11 or 21. The memory 12 or 22 works with the processor 11 or 21 and stores various information to operate the processor 11 or 21. The transceiver 13 or 23 works with the processor 11 or 21, and the transceiver 13 or 23 sends and / or receives radio signals.

[0061] The processor 11 or 21 may include an application specific integrated circuit (ASIC), other chipsets, logic circuits and / or data processing devices. The memory 12 or 22 may include a read-only memory (ROM), a random access memory (RAM), a flash memory, a memory card, a storage medium and / or other storage devices. The transceiver 13 or 23 may include a baseband circuit for processing radio frequency signals. When the embodiment of the present invention is implemented in software, the technology described in the present invention may be implemented by executing the functional modules (e.g., procedures, functions, etc.) described in the present invention. The modules may be stored in the memory 12 or 22 and executed by the processor 11 or 21. The memory 12 or 22 may be integrated inside the processor 11 or 21, or may be implemented outside the processor 11 or 21, in which case they may be communicatively coupled with the processor 11 or 21 in various ways known in the art.

[0062] The present invention proposes a potential method for handling XR jitter in DRX.

[0063] Configuring a DRX pattern with periodicity or some time offset for the corresponding DRX cycle may help match the XR traffic. Figure 2 As shown in Figure 1, when XR packets arrive with jitter, configuring the mode or time offset is no longer useful. Since jitter can cause large delays, it is necessary to handle XR jitter for DRX. One way to do this is to configure a larger DRX-onDurationTimer value to cover the jitter range. However, a larger DRX-onDurationTimer value will result in higher power consumption. Therefore, some potential enhancements should be considered.

[0064] Figure 3 is a flow chart of a wireless communication method according to a first embodiment of the present invention. Figure 1 and Figure 3 , the method 100 includes the following contents. In step 110, the UE 10 is configured by the base station 20 with one or more discontinuous reception (DRX) configurations, each of which includes one or more on-durations (DRX-ondurations) matching one or more services. Using this method, the jitter of the XR data packet can be covered by the on-duration, thereby improving the XR traffic service.

[0065] When configuring DRX, the DRX-on duration (DRX-on duration) can be understood as the time controlled by the DRX-on duration timer (DRX-onDurationTimer). The following description in this article uses "DRX-onDurationtimer" for illustration. It should be noted that the terms "DRX-on duration DRX-on duration" and "DRX-onDurationTimer DRX-onDurationTimer" are equivalent and interchangeable in most cases based on the spirit and meaning of the present invention.

[0066] In the first embodiment, multiple values ​​of DRX-onDurationtimer can be configured. Using this method, when there is no jitter when the data packet arrives, the regular DRX-onDurationtimer of the DRX cycle can be configured to the UE, and when there is jitter when the data packet arrives, the unconventional DRX-onDurationtimer of the DRX cycle can be configured to the UE. The time length of the unconventional DRX-onDurationtimer is greater than the regular DRX-onDurationtimer, and the DRX-on duration can cover the jitter range. Figure 4 As shown, the regular DRX-onDuration timer is configured for DRX cycle 1 and DRX cycle 2, and the irregular DRX-onDuration timer is configured for DRX cycle 3. The value of the irregular DRX-onDuration timer is different from that of the regular DRX-onDuration timer. In some embodiments, multiple values ​​of DRX-onDuration are cycled in the DRX cycle.

[0067] In some embodiments, a UE fixed mode can be configured for XR services. Two types of DRX on-duration timers DRX-onDurationtimer can be considered. One is a conventional DRX on-duration timer DRX-onDurationtimer, and the other is an unconventional DRX on-duration timer DRX-onDurationtimer. A set of DRX on-duration timer DRX-onDurationtimer values ​​can be configured to the UE. The values ​​of the set of DRX on-duration timer DRX-ondurationtimer may include conventional values ​​and unconventional values ​​of DRX-onDurationtimer. A corresponding time offset group may also be configured to the UE, wherein each DRX-onDurationtimer in the time offset group is associated with the corresponding set of time offset values. This pattern can be cyclic in time.

[0068] In some embodiments, a set of values ​​of the DRX-onDuration timer DRX-onDurationtimer and a time offset of the DRX-onDurationtimer within a certain number of cycles may be configured.

[0069] In some embodiments, a jitter time window may be introduced. Within the jitter time window, DRX-onDurationtimer is configured as an unconventional DRX on-duration timer DRX-onDurationtimer (default mode), and the conventional DRX-onDurationtimer may be used outside the jitter time window in the time domain.

[0070] In the second embodiment, if no PDCCH is detected during the DRX-on duration timer DRX-onDurationTimer, an additional DRX active time or an additional DRX on duration timer DRX-onDurationTimer will be triggered, where the additional DRX active time or DRX-onDurationTimer may be predefined. The DRX active time indicates that the UE is in an awake state or in an active time, and the UE monitors the PDCCH during the active time. In some embodiments, the additional DRX active time or DRX-onDurationTimer is indicated by the gNB. The start of the additional DRX active time or DRX-onDurationTimer is indicated by the gNB, which is similar to the determination of the additional DRX-on described in the first possible implementation of the second embodiment below. For details, please refer to the first possible implementation of the second embodiment.

[0071] In a third embodiment, a sliding DRX-onDurationtimer may be configured. A time offset set and a reference or default value of a DRX on duration timer DRX-onDurationtimer may be configured to the UE, wherein the time offset is used to indicate the start of the DRX on duration timer DRX-onDurationtimer and the reference or default value is used to determine the actual duration of the DRX on duration timer DRX-onDurationtimer. New RRC signaling or drx-LongCycleStartOffset may be used to indicate the time offset set, and new RRC signaling or DRX-onDurationTimer in DRX-config may be used to indicate the reference value or default value of the DRX-onDurationTimer.

[0072] In some embodiments, when the sliding DRX-onDurationtimer is enabled, a UE is woken up and starts monitoring the PDCCH at the start of the DRX-onDurationtimer, which is represented as time i. When the UE monitors the DCI at time j, the actual DRX-onDurationtimer starts at time i, and the duration of the DRX-onDurationtimer is "reference or default value + j-i+1" or "reference or default value + ji". The time units of i and j can be symbols, time slots or milliseconds.

[0073] In some cases, the DRX cycle can be configured with the start of the DRX-onDuration timer DRX-onDurationtimer. The UE wakes up at the start of the time, which is represented by a time offset, such as Figure 5 As shown. Taking DRX cycle 3 as an example, the green arrow is the start time of the DRX on-duration timer DRX-onDurationtimer in DRX cycle 3, and the red arrow is the time position when the UE detects the PDCCH in DRX cycle 3. Then the actual value of the DRX on-duration timer DRX-onDurationtimer 3 (DRX-onDurationtimer of DRX cycle 3) is equal to "the time position of the red arrow - the time position of the green arrow + 1 + reference or default value" or "the time position of the red arrow - the time position of the green arrow + reference or default value", where the unit of the time position and the reference or default value can be symbol or time slot or millisecond. That is, the reference will apply to the first PDCCH reception after the start of the DRX-on duration.

[0074] In some cases, the DRX-onDurationTimer mode can be configured within a cycle, such as Figure 6 As shown. The green arrow indicates the start time of the DRX-onDurationtimer in the time period, and the red arrow indicates the time position at which the UE detects the PDCCH in the time period. Then the real number of a DRX-onDurationtimer is equal to "the time position of the red arrow - the time position of the green arrow + 1 + the reference or default value" or "the time position of the red arrow - the time position of the green arrow + the reference or default value", where the position of the red arrow is the PDCCH closest to the position of the green arrow.

[0075] In some embodiments, RRC signaling is introduced to enable or disable the sliding DRX-onDurationtimer function of DRX.

[0076] In some embodiments, the sliding DRX-onDuration timer DRX-onDurationtimer is disabled when the following conditions are met. - During the duration from the start of the DRX-on duration timer DRX-onDurationtimer to "DRX-onDuratinotimer start + reference or default value", the UE monitors the PDCCH.

[0077] In the fourth embodiment, a larger DRX-onDurationtimer value is configured, which can cover the jitter range and skip some parts of the DRX-onDurationtimer. Figure 7 As shown in Figure 1, a larger DRX-onDurationTimer, i.e., DRX cycle 2, is configured to cover the jitter of XR. However, this will result in more power consumption due to the increased wake-up time of the UE. The DCI signal can be used to indicate PDCCH skipping, and the UE can enter the sleep state during the skipped time, such as Figure 7 When the UE monitors the PDCCH that skips the DCI, the UE can skip multiple PDCCH monitoring events and enter the sleep state during this period. Figure 7 As shown, some PDCCH monitoring opportunities of each DRX-on duration are skipped in a discrete manner. The DCI may be a UE-specific DCI, a set of common DCIs, a new format DCI, or a new RNTI scrambled DCI. In some embodiments, the PDCCH skip indication signaling may be based on MAC-CE.

[0078] In some embodiments, the DRX-onDuration timer DRX-onDurationtimer can be divided into several parts, each part of the DRX-onDuration timer DRX-onDurationtimer has its own PDCCH monitoring opportunity (dense or sparse PDCCH monitoring opportunities or different search space configurations). Figure 8 As shown, the DRX-onDurationTimer in DRX cycle 1 is divided into two parts, part 1-1 and part 1-2, part 1-1 has sparse PDCCH monitoring opportunities, and part 1-2 has dense PDCCH monitoring opportunities. The DRX-onDurationTimer in DRX cycle 2 is divided into three parts, part 2-1, part 2-2, and part 2-3, part 2-1 and part 2-3 have sparse PDCCH monitoring opportunities, and part 2-2 has dense PDCCH monitoring opportunities.

[0079] In some embodiments, several components and corresponding PDCCH monitoring opportunities are pre-configured and cycled in time.

[0080] In some embodiments, the search space configuration of each portion is different or the same.

[0081] In a fifth embodiment, multiple active DRX configurations (a set of active DRX configurations) are configured. A DRX configuration set includes one or more DRX. A dynamic or semi-static method can be used to activate or switch to a DRX configuration in the set, such as Fig. 9 As shown. Multiple active DRX configurations can solve the delay problem caused by Jitter. The UE should wake up at any DRX-onDurationTimer in multiple active DRX configurations. For example, the UE needs to wake up at any DRX-onDurationTimer of DRX 1, DRX 2, and DRX 3.

[0082] In some embodiments, it is possible to consider dynamically activating a set of DRX configurations, wherein the DRX configuration set includes one or more DRXs. It is possible to consider introducing an index for each DRX (for example, adding an information element (IE) in the DRX-config) and configuring the DRX table to activate or deactivate multiple DRXs. Each row in the table contains one or more DRXs (for example, the index of the DRX), and the activation or deactivation of the DCI represents a row index of the table, and then a set of DRX configurations associated with the index should be activated or deactivated. The DCI can be a UE-specific DCI or a group-common DCI, or it can be a new RNTI-scrambled DCI or a DCI of a new format. In some embodiments, a set of DRXs can be activated or deactivated by MAC-CE.

[0083] In some embodiments, the DRX configuration can be switched dynamically. The DCI includes DRX configuration activation and deactivation information. For example, two fields in the DCI, one for activating the DRX configuration and the other for deactivating the DRX configuration. In some cases, if only one DRX can be activated at a time, when the DCI activates a new DRX, it means that the currently activated DRX configuration should be deactivated.

[0084] In some embodiments, multiple DRX configurations are configured, but only one of them is activated at a time. A default DRX configuration may be configured, or one of the DRX configurations may be activated by a DCI. If the UE does not monitor any PDCCH on the DRX on-duration timer DRX-onDurationtimer in the active DRX configuration, the closest DRX configuration among the multiple DRX configurations will be activated, where the closest DRX configuration is defined as the configuration closest to the currently activated DRX configuration in which no DCI is detected. The UE needs to wake up at the start of the DRX on-duration timer DRX-onDurationtimer in the most recent DRX configuration, which corresponds to the DRX-onDurationtimer of the currently activated DRX configuration in which no DCI is detected. When all relevant timers have expired, the most recent DRX configuration will be deactivated. Fig.10 As shown, three DRX configurations are configured. DRX 1 (indicates DRX configuration 1) is configured as the default configuration or activated by DCI. When the UE does not detect PDCCH during Drx on 2, DRX 2 will be activated. The UE needs to wake up at the start of Drx on 2 in DRX 2 and deactivate DXR2 when the timer of Drx on 2 runs out.

[0085] In some embodiments, the DRX-onDuration timer DRX-onDurationtimer in the closest DRX configuration overlaps with the DRX-onDuration timer DRX-onDurationtimer of the currently active DRX configuration, in which no DCI is detected. In some embodiments, the DRX-onDuration timer DRX-onDurationtimer in the closest DRX configuration does not overlap with the DRX-onDurationtimer of the currently active DRX configuration, in which no DCI is detected.

[0086] In a sixth embodiment, a negative integer set is configured, wherein the negative integer set includes one or more negative values. The signal may indicate a value in the set and modify the start of the next one or more DRX-onDuration timers DRX-onDurationtimer, such as Fig.11 As shown. DRX is configured, the base station (e.g., gNB) wants to modify the start of Drx on 3, and the signaling (before Drx on 3 or Drx on 2) indicates a negative integer -i, then the start of Drx on 3 (t1) is equal to: t2-i+1 or t2-i. In some embodiments, the granularity of t1 and t2 is symbol or slot or ms.

[0087] In some embodiments, the set of negative integers may be configured by RRC signaling. In some embodiments, the set of negative integers may be dynamically indicated by DCI or MAC CE signaling. In some embodiments, the set of negative integers is configured by RRC signaling, and the DCI or MAC CE indicates that one of the values ​​in the set is a UE.

[0088] In some embodiments, a set of integers may be configured, wherein the set of integers includes one or more positive integers or multiple positive integers or negative integers. Signaling may indicate a value in the set and modify the start of the next one or more DRX-onDurationtimers. If the value is a positive integer, it indicates that the start time of the DRX-onDurationtimer is postponed. If the value is a negative integer, it indicates that the start of the DRX-onDurationtimer is advanced.

[0089] This disclosure proposes potential methods to trigger additional transmission opportunities for XR.

[0090] Low power consumption is very important for many types of devices such as smart glasses, smartphones, and tablets for XR applications and Could Gaming. DRX is one of the effective ways for UE to save power. When the UE enters the DRX-OFF state, it will suspend for PDCCH monitoring and can enter a dormant state to save UE power. In the current 3GPP specification, the UE needs to monitor the PDSCH in the case of configured semi-persistent scheduling (SPS), regardless of whether it is in DRX ON or OFF when DRX is configured. When the UE is configured with DRX, the UE only monitors the PDCCH in the DRX-ON state. In addition, the UE can also transmit PUSCH on the configured grant (CG) resources. Assuming that the UE is configured with DRX and CG / SPS configuration, when the UE is in the DRX-OFF state and a large transport block (TB) arrives before the SPS transmission event, the gNB can use SPS to transmit the TB. Due to the large size, the SPS resources can only transmit part of the TB, and the rest needs to be postponed until the UE turns to DRX-ON. However, it will cause a large alignment delay. Potential methods for triggering additional activity time can be considered.

[0091] Fig.12 A flow chart of a wireless communication method according to a second embodiment of the present invention is shown. Fig.12 , the method 200 includes the following contents. In step 210, the UE 10 is configured by the base station 20 with discontinuous reception (DRX) and / or with configuration grant (CG) and / or semi-persistent scheduling (SPS) opportunities. In step 220, the UE 10 is configured by the base station 20 with an additional DRX-on duration or an additional DRX active time, after a CG physical uplink shared channel (PUSCH) / SPS physical downlink shared channel (PDSCH), wherein the additional DRX-on duration or the additional DRX active time is triggered or not triggered. Using this method, the latency of the XR service can be improved.

[0092] The DRX active time means that the UE is in an awake state or in an active time, and the UE monitors the PDCCH during the active time.

[0093] In the first embodiment, for CG, other preset values ​​of DRX-onDurationTimer can be configured. UCI signaling can be used to trigger an additional DRX on duration timer DRX-onDurationtimer, where UCI is carried on CG PUSCH and the duration of the additional DRX-on is pre-configured by RRC signaling. Fig.13As shown, when the UE sends PUSCH on CG 2 and the PUSCH carries UCI to indicate whether to trigger additional DRX-on (DRX-onDurationtimer). For example, if only a default value of the additional DRX-onDuratinotimer is used, the size of the UCI is 1 bit. When the status of the UCI is "1", it means that the additional DRX on duration timer DRX-onDurationtimer is triggered. When the status of the UCI is "0", it means that the additional DRX on duration timer DRX-onDurationtimer will not be triggered.

[0094] In addition, the start of the additional DRX-onDuration timer DRX-onDurationtimer should also be determined. Two methods can be considered:

[0095] 1) UCI ​​indicates the value of k, where k can be symbol, slot or millisecond. The reference point for the start of the additional DRX-ondurationtimer is based on the slot, end slot or start slot of the CG PUSCH carrying the UCI. Fig.14 As shown, the start time of the additional DRX on-duration timer DRX-onDurationtimer is: time slot i+k or time slot i+k-1. In some embodiments, the reference point at which the additional DRX on-duration timer DRX-onDurationtimer starts is based on the first symbol of the CGPUSCH carrying the UCI or the last symbol of the CG PUSCH carrying the UCI or the start symbol of the UCI or the end symbol of the UCI. The start time of the additional DRX on-duration timer DRX-onDurationtimer is: reference point+k or reference point+k-1.

[0096] 2) Another method for determining the start time of the additional DRX-OnDurationTimer is based on the UE capability type. Different types of UEs have different processing times. The start time (e.g., time slot) of the additional DRX-onDurationtimer is the nearest time slot greater than the processing time, where the processing time is predefined and the processing time starts from the end symbol of the CG PUSCH.

[0097] For SPS, the default value of the additional DRX-ondurationtimer can be configured. DCI signaling can be used to trigger the additional DRX on duration timer DRX-onDurationtimer, where the DCI is carried on the SPS PDSCH. The duration of the additional DRX on duration timer DRX-onDurationtimer is pre-configured by the RRC signal. Similarly, the method for determining the start of the additional DRX on duration timer DRX-onDurationtimer for the CG can also be used for SPS.

[0098] In some embodiments, whether to trigger an additional DRX-on duration timer DRX-onDurationtimer may be configured, and RRC signaling may be used to enable or disable the function.

[0099] In the second embodiment, for the CG, a set of additional DRX on-duration timer DRX-onDurationtimer values ​​can be configured. UCI represents one of the values ​​of a set of different durations of additional DRX on-duration timer DRX-onDurationtimer (or a set of additional DRX on-duration timer DRX-onDurationtimer). The size of UCI is related to the size of the set of additional DRX on-duration timer DRX-onDurationtimer. Each state of UCI can indicate a value in the set of additional DRX on-duration timer DRX-onDurationtimer, where UCI is carried on the CG PUSCH. For example, the number of this set of values ​​is 4, and the UCI size is 2 bits, as shown in Table 1. Table 1. Relationship between UCI and collection UCI Status definition 00 The first value in the collection 01 The second value in the set 10 The third value in the set 11 The fourth value in the set

[0100] In the above method, a similar method may be applied to determine the start time of other DRX-onDuration timers DRX-onDurationtimer.

[0101] For SPS, a set of additional DRX-on duration timer DRX-onDurationtimer (or a set of additional DRX-on duration timers) values ​​can be configured. DCI is used to indicate a value in the set. The size of the DCI is related to the size of the set. Each state of the DCI can indicate a value in the set, where the DCI is carried on the SPS PDSCH.

[0102] In some embodiments, whether to trigger an additional DRX-on duration timer DRX-onDurationtimer may be configured, and RRC signaling may be used to enable or disable this function.

[0103] The present disclosure proposes a potential method for skipping unused CG / SPS transmissions. In addition, a method for triggering a retransmission timer should also be provided.

[0104] In the current 3GPP specification, the UE needs to monitor the PDSCH at the configured SPS opportunity, regardless of whether it is DRX ON or DRX OFF when DRX is configured. However, when the UE is in active time, receiving PDSCH using a dynamic scheduling method has greater flexibility in resource allocation and HARQ-ACK feedback. Therefore, a method to skip SPS / CG should be considered. In addition, when sending or receiving CG / SPS, a timer for retransmission (such as drx-RetransmissionTimerUL or drx-RetransmissionTimerDL) can be configured to ensure reliability. However, the XR service has a very low requirement for the Block Error Rate (BLER), so the possibility of retransmission is also low. Since the UE requires a duration wake-up timer after each CG / SPS transmission, it will result in greater power consumption. Therefore, some enhanced methods can be studied to solve this problem.

[0105] Fig.15 is a flow chart of a wireless communication method according to a third embodiment of the present invention. Fig.15 , method 300 includes the following. In step 310, UE 10 is configured with discontinuous reception (DRX) and / or CG / SPS by base station 20, and indicates whether to skip one or more configured grant (CG) / semi-persistent scheduling (SPS) opportunities within the DRX on duration, or whether to skip DRX retransmission opportunities. In step 310, if one or more CG / SPS opportunities are skipped within the DRX on duration, PUSCH is not sent or PDSCH is not received on the CG / SPS configuration corresponding to the one or more CG / SPS opportunities. Using this method, XR power saving can be achieved.

[0106] In a first embodiment, a default method can be used to indicate whether one or more CG / SPS opportunities can be skipped during the DRX on-duration timer DRX-onDurationtimer. Skipping CG / SPS means that the UE will not transmit PUSCH or receive PDSCH on the corresponding CG / SPS configuration (when skipping SPS, the HARQ feedback corresponding to SPS will also be skipped). If the time domain resources of the CG / SPS configuration completely overlap with the DRX-onDurationTimer, the CG / SPS configuration can be skipped. In some embodiments, if the time domain resources of the CG / SPS configuration partially overlap with the DRX-onDurationTimer, the CG / SPS configuration can be skipped. In some embodiments, if the time domain resources of the CG / SPS configuration completely overlap with the DRX active time, the CG / SPS configuration can be skipped. In some embodiments, if the time domain resources of the CG / SPS configuration partially overlap with the DRX active time, the CG / SPS configuration can be skipped.

[0107] In the second embodiment, a semi-static mechanism can be considered to introduce RRC signaling to indicate whether one or more CG / SPS opportunities can be skipped during the DRX-onDurationtimer. If the RRC signaling indicates that the CG / SPS skip is "disabled", the UE needs to transmit PUSCH and receive PDSCH on each CG / SPS configuration. If the RRC signal indicates that the CG / SPS skip is "enabled", the UE needs to skip the CG / SPS during the DRX-onDurationtimer. CG / SPS skipping means that the UE will not transmit PUSCH or receive PDSCH on the corresponding CG / SPS configuration (when skipping SPS, the HARQ feedback corresponding to SPS will also be skipped). If the time domain resources of the CG / SPS configuration completely overlap with the DRX-onDurationTimer, the CG / SPS configuration can be skipped. In some embodiments, if the time domain resources of the CG / SPS configuration partially overlap with the DRX-onDurationTimer, the CG / SPS configuration can be skipped. In some embodiments, if the time domain resources configured by CG / SPS completely overlap with the DRX active time, the CG / SPS configuration can be skipped. In some embodiments, if the time domain resources configured by CG / SPS partially overlap with the DRX active time, the CG / SPS configuration can be skipped.

[0108] In a third possible implementation, a scheduled DCI (scheduled data transmission) (e.g., a UE-specific DCI) or a non-scheduled DCI (scheduled data transmission without data transmission) (e.g., a group-common DCI) is used to indicate whether a CG / SPS or a group of CG / SPS or a portion of a CG / SPS can be skipped. In some embodiments, a MAC CE or DCI piggyback of a PDSCH or a UCI piggyback of a PUSCH can be used to indicate whether a CG / SPS or a group of CG / SPS or a portion of a CG / SPS can be skipped.

[0109] To further save UE power consumption, the timer used for retransmission (e.g. drx-RetransmissionTimerUL or drx-RetransmissionTimerDL) can be optimized when sending or receiving CG / SPS (DRX is also configured).

[0110] Generally speaking, the retransmission probability of XR TB is very low (0.01 or 0.001), so the UE does not need to wake up during most retransmission times. In the current 3GPP specification, if the DRX retransmission timer RetransmissionTimerUL or drx-RetransmissionTimerDL is configured, the UE needs to wake up after CG / SPS transmission / reception to detect the retransmission authorization. However, using this mechanism will result in greater power consumption. Therefore, it is possible to study how to skip the DRX retransmission timer drx-RetransmissionTimer for DL / UL.

[0111] In the first alternative embodiment, an RRC signaling is introduced to enable or disable the retransmission time skipping of CG / SPS. If the RRC signaling is configured as "enabled", it means that the UE can skip the DRX retransmission timer drx-ReTransmissionTimer on DL / UL after transmitting CG or receiving SPS. If the RRC signaling is configured as "disabled", it means that the UE cannot skip the DRX retransmission timer drxReTransmissionTimer on DL / UL after transmitting CG or receiving SPS.

[0112] In a second alternative embodiment, for CG configuration, UCI may indicate whether to skip the DRX retransmission timer drx-ReTransmissionTimerUL. UCI is carried on the CG PUSCH. For example, assuming that the UCI size is 1 bit, if the UCI shows "1", it means that the UE can skip the DRX retransmission timer drx-ReTransmissionTimerUL after CG transmission. If the UCI shows "0", it means that the UE cannot skip the DRX retransmission timer drx-ReTransmissionTimerUL after CG transmission. Fig.16 As shown, if the UCI indication is "1", drx-ReTransmissionTimer 1 will be skipped.

[0113] For SPS configuration, DCI can indicate whether to skip the DRX retransmission timer drx-ReTransmissionTimerDL. DCI is carried on the SPS PDSCH. For example, assuming that the DCI size is 1 bit, if the DCI shows "1", it means that the UE can skip drx-ReTransmissionTimerDL after receiving SPS. If the UCI indicates "0", it means that the UE cannot skip drx-ReTransmissionTimerdL after re-verifying SPS.

[0114] In a third alternative implementation, whether to skip drx-ReTransmissionTimerDL / UL depends on the packet delay budget (PDB) and the duration between the last symbol or timeslot of CG / SPS and the next DRX-onDurationTimer. If the delay is greater than the threshold, the UE cannot skip drx-ReTransmissionTimerDL / UL. If the delay is less than the threshold, the UE can skip drx-ReTransmissionTimerDL / UL. The delay is defined as the duration between the last symbol of CG / SPS and the start symbol of DRX-onDurationTimer next to CG / SPS. The threshold or parket delay budget can be predefined. Taking CG as an example, Fig.17 As shown, if the delay is greater than the data packet delay budget, the UE cannot skip the DRX retransmission timer drx-ReTransmissionTimer1; if the delay is less than the data packet transaction budget, the UE can skip the DRX retransmission timer drx-ReTransmissionTimer1.

[0115] The present disclosure proposes a potential method for PDCCH adaptation (PDCCH skipping and search space group switching) through non-scheduled DCI. In the current 3GPP specification, PDCCH adaptation is based on scheduled DCI and does not support non-scheduled DCI. This means that PDCCH adaptation is not performed when there is no data transmission. However, this is not friendly to power saving and delay-sensitive traffic. In addition, in the current 3GPP specification, the RRC value of the PDCCH skip duration can be represented by DCI at most. However, in some cases, these values ​​do not match the XR service. For example, the value is too small or too large.

[0116] Fig.18 is a flow chart of a wireless communication method according to a fourth embodiment of the present invention. Fig.18 , the method 400 includes the following contents. In step 410, no data transmission is scheduled by non-scheduled downlink control information (DCI), and the UE 10 is indicated by physical downlink control channel (PDCCH) adaptation related to PDCCH skipping and search space group switching. Using this method, PDCCH adaptability is enhanced.

[0117] The following methods can be considered for PDCCH adaptation. 1. Non-scheduled DCI is used to indicate PDCCH adaptation, and the size of non-scheduled DCI can be configured. 2. In the scheduled DCI, the reserved field can be used to indicate PDCCH skipping. The reserved field can be redefined as the remaining PDCCH after skipping for a period of time, where the duration can be predefined or the remaining duration of the DRX-onDurationTimer or the remaining duration of the DRX active time. 3. Configure a set of PDCCH skip modes for XR, and then the scheduled DCI or non-scheduled DCI can be used to indicate the value in the set.

[0118] The commercial benefits of some embodiments are as follows. 1. Solve problems in the prior art 2. Promote XR traffic services. 3. Improve latency. 4. Improve power saving effect of XR. 5. Enhance PDCCH adaptability 6. Provide good communication performance.
