Description

[Technical Field]

[0001] This document relates generally to wireless communications. [Background technology]

[0002] Extended Reality (XR) is a term that stands for Augmented Reality (AR), Mixed Reality (MR), or Virtual Reality (VR). XR technology combines the real world with virtual information generated by digital devices. In this way, XR allows users to perceive an immersive experience in a mixed reality virtual environment. To support high-quality XR services, a network requires both high data rates and low latency.

[0003] Discontinuous reception (DRX) is a power-saving mechanism. For user equipment (UE) in connected mode (e.g., RRC_CONNECTED), DRX is referred to as connected DRX (CDRX). Generally, CDRX can be performed to control the UE's physical downlink control channel (PDCCH) monitoring operation for power saving when DRX is configured. For example, as shown in FIG. 1, when XR (downlink) traffic arrives at the gNB, the gNB can deliver a PDCCH for scheduling DL packets for the XR downlink traffic when the UE is within each DRX-on period. On the UE (i.e., receiver) side, the PDCCH can be monitored within the DRX-on state (i.e., on duration) interval, and the DL packet can be successfully decoded based on the detected PDCCH. During the DRX-off state interval, the UE does not need to monitor the PDCCH to save power. Therefore, if a packet arrives within that interval, it is delayed to the next on duration.

[0004] Although XR traffic is expected to be generated periodically, variable video encoding times, packet sizes, and network transmission times can introduce a level of jitter in the XR traffic reaching the gNB. In some cases, the jitter can be unpredictable. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION

[0058] The mechanism for starting the drx-onDurationTimer is described as follows. If the UE's drx-onDurationTimer is running, the UE is considered to be in the drx on state shown in Figure 1. Additionally, the inactivityTimer may continue to run when the drx-onDurationTimer expires. The UE is considered to be in active time (i.e., the drx on state) when the drx-onDurationTimer or the inactivityTimer is running.

[0059] In some embodiments that determine when to start the drx-onDurationTimer, the DRX mechanism is defined as follows:

[0060] 1. If a short DRX cycle (i.e., drx-ShortCycle) is used for the DRX group and [(SFN × 10) + number of subframes] modulo(drx-ShortCycle) = (drx-StartOffset) modulo(drx-ShortCycle), - Start the drx-onDurationTimer for this DRX group after drx-SlotOffset from the beginning of the subframe.

[0061] 2. If a long DRX cycle (i.e., drx-LongCycle) is used for the DRX group and [(SFN × 10) + number of subframes] modulo (drx-LongCycle) = drx-StartOffset, - Start the drx-onDurationTimer for this DRX group after drx-SlotOffset from the beginning of the subframe.

[0062] According to one embodiment, the Radio Resource Control (RRC) controls the DRX operation by configuring the following parameters: -drx-onDurationTimer: Duration at the start of a DRX cycle; -drx-SlotOffset: Delay before starting drx-onDurationTimer; -drx-InactivityTimer: the period after a PDCCH monitoring opportunity during which the PDCCH indicates a new UL or DL ​​transmission to the MAC entity; -drx-RetransmissionTimerDL (per DL HARQ process excluding broadcast process): maximum duration until DL retransmission is received; -drx-RetransmissionTimerUL (per UL HARQ process): maximum duration until a grant for UL retransmission is received; -drx-LongCycleStartOffset: drx-StartOffset defining the subframe in which the long DRX cycle and the long-short DRX cycle start; -drx-ShortCycle(optional): Short DRX cycle; -drx-ShortCycleTimer (optional): the period during which the UE should follow the short DRX cycle; -drx-HARQ-RTT-TimerDL (per DL HARQ process excluding broadcast process): minimum period before DL allocation for HARQ retransmission is expected by the MAC entity; -drx-HARQ-RTT-TimerUL (per UL HARQ process): minimum period before which a UL HARQ retransmission grant is expected by the MAC entity; In this disclosure, the prefix of each parameter may be omitted, for example, drx-onDurationTimer is also referred to as onDurationTimer in this context.

[0063] Additionally, the drx-onDurationTimer and / or the drx-InactivityTimer may be a duration or may be a precise timer that may run within a duration.

[0064] In the present disclosure, a period may be configured / defined via higher layer signaling (e.g., RRC signaling) to indicate a time interval during which a UE is allowed to monitor downlink control information (DCI) scheduling (e.g., a physical downlink control channel (PDCCH)). For example, the UE may monitor DCI scheduling within a period that may fall outside of an onDurationTimer and / or an inactivityTimer. In the present disclosure, a period configured by higher layer signaling to indicate a time interval during which a UE is allowed to monitor DCI scheduling is also referred to hereinafter as a "period" or a "time window."

[0065] 2 shows a schematic diagram of a configured period according to one embodiment of the present disclosure. As shown in FIG. 2, XR traffic is assumed to arrive at the gNB when the UE is within each DRX-on period. However, due to jitter, XR traffic may arrive at the gNB when the UE may be within a DRX-off period. Under such circumstances, traffic must be transmitted during the subsequent DRX-on period, resulting in reduced network performance.

[0066] By configuring the period during which the UE is allowed to monitor the PDCCH (during the DRX off period), the UE is guaranteed to detect scheduling at the corresponding PDCCH monitoring opportunity, even if the scheduling is not transmitted until the configured / defined period (due to jitter). In addition, the mechanism is flexible to allow the UE to perform PDCCH monitoring during the configured period on demand. Furthermore, in this case, legacy power saving techniques (e.g., DRX) can be applied without increasing design complexity, taking into account the impact of jitter.

[0067] The operation / design at the UE side according to the embodiment of the present disclosure is as follows. A. Receiving higher layer signaling In one example, the UE may receive higher layer signaling. In one embodiment, the higher layer signaling may be RRC signaling (e.g., "XR-r18"). The higher layer signaling may be / include a bit that is an indication of the presence of XR-specific configuration and / or an indication that enables new functionality in the network.

[0068] For example, if the bit has a value of '1', the network has an XR-specific RRC configuration. Alternatively, or in addition, a bit having a value of '1' or '0' indicates that at least one of the DCI format configuration, MAC CE configuration is configured for transmission or reception of control information.

[0069] Alternatively, the value of the bit is "1" or "0" to indicate whether service-related configuration and / or 5G QoS Identifier (5QI) and / or priority configuration is configured for transmission or reception of control / data information.

[0070] In one example, higher layer signaling is configured per UE, per bandwidth portion, and / or per cell.

[0071] For example, RRC signaling (eg, "XR-r18") may be broadcast to a group of UEs or unicast to the UEs.

[0072] B. Receive a specific RRC configuration with configured duration In one example, specific RRC signaling is received for a particular configuration of parameters, e.g., in the time domain. In one embodiment, the RRC signaling is transmitted for DRX operation / configuration, and more specifically, for time domain parameters associated with the DRX operation / configuration.

[0073] In some embodiments, the UE-specific RRC signaling is configured per UE. In one example, a period / window is configured.

[0074] In some embodiments, parameters related to the duration of the period / time window are configured to configure the period / time window. In addition, parameters related to the reference point or the first PDCCH monitoring opportunity may also be configured in the RRC signaling. Note that the reference point or the first PDCCH monitoring opportunity may be implicitly determined without a corresponding parameter (e.g., the reference point may be predefined).

[0075] 3 shows a schematic diagram of a configured time window according to one embodiment of the present disclosure. For each DRX cycle shown in FIG. 3, a period is configured to start from the end of onDurationTimer, and the duration of the period is also configured by the duration parameter. In this embodiment, the start point of the period is considered as a reference point that can be derived from legacy DRX parameters (e.g., onDurationTimer).

[0076] In some embodiments, the duration parameter is indicated by the number of search space sets. For example, the duration (parameter) may be 2*n search space sets, where n is a positive integer.

[0077] In some embodiments, the duration parameter is indicated by the number of PDCCH monitoring opportunities. For example, the duration is 2 n There may be n PDCCH monitoring opportunities, where n is an integer.

[0078] In some embodiments, the duration parameter is explicitly configured by the network. For example, the network may configure the duration parameter in units of milliseconds (ms) or slots. In one embodiment, the duration may be 1 / 2, 1 / 3, or 1 / 4 of the duration of the configured drx-onDurationTimer. Alternatively, or in addition, the duration may be one or more PDCCH monitoring occasions, or in the range of 1 ms to 16 ms.

[0079] In some embodiments, the time window starts at the first PDCCH monitoring opportunity or at the first symbol of the first slot after the end / expiry of the onDurationTimer or inactivityTimer.

[0080] 4 shows a schematic diagram of a time window according to one embodiment of the present disclosure. In FIG. 4, the duration starts at the end / expiry of the inactivityTimer. That is, in this embodiment, the reference point is configured / predefined as the end / expiry of the inactivityTimer.

[0081] In some embodiments, the time window starts at the first PDCCH monitoring opportunity in slot n+k or the first symbol in slot n+k, and the onDurationTimer or inactivityTimer ends in slot n. In one embodiment, k is an integer. In these embodiments, the new parameter "k" is configured with a corresponding "duration" parameter.

[0082] In one embodiment, the units of the configured parameter k may be milliseconds, slots or symbols.

[0083] In one embodiment, the units of the configured duration parameter may be milliseconds or slots.

[0084] In some embodiments, the time window starts at the first PDCCH monitoring opportunity in slot n+k or the first symbol in slot n+k, and the onDurationTimer or inactivityTimer starts in slot n. In one embodiment, k is an integer.

[0085] In some embodiments, the timer period starts or ends at a time that is a time offset after the first or last CG PUSCH or SPS PDSCH resource. Figure 5 shows a schematic diagram of a time window according to one embodiment of the present disclosure. In Figure 5, the end of the time window is at a time that is an offset after the last SPS PDSCH resource.

[0086] In some embodiments, the period is configured using absolute time with a system frame number (SFN) index / number and a slot index / number.

[0087] C. The UE activates a time window, or activates a timer, or reactivates an inactivityTimer, or extends an onDuration timer.

[0088] In one example, an indication of whether or not to activate the time window / timer is configured. In some embodiments, the UE receives an indication from the BS of whether to activate a configured time window / timer associated with the time period.

[0089] In some embodiments, the indication includes Downlink Control Information (DCI), a DCI format, a DCI bit field, a MAC CE, or a reference signal. In one embodiment, the DCI format may be a UE-specific DCI format. In one embodiment, the DCI format is received at the last PDCCH monitoring opportunity, the time interval of a running onDurationTimer or a running inactivityTimer, the first PDCCH opportunity after expiration of the onDurationTimer, or a DRX off period.

[0090] In some embodiments, the DCI may have the same format as DCI format 2_6 and further includes an indication of whether to activate a time window / timer. In one embodiment, the DCI includes a bit field indicating (1) whether to activate a time window / timer and / or (2) the duration of the time window / timer.

[0091] In some embodiments, the UE receives a MAC CE that indicates whether to activate a time window / timer.

[0092] In some embodiments, the UE receives a reference signal that indicates whether to activate a time window / timer. The reference signal may be a sounding reference signal (SRS), a channel state information reference signal (CSI-RS), a pseudo random (PN) sequence, or a Zadoff-chu (ZC) sequence.

[0093] In one example, the validity time of the instruction may also be configured. In some embodiments, the effective time for the activation of the timer may be configured / defined. For example, the effective time refers to the number of DRX cycles during which the time window / indication of whether to activate the timer is valid. The effective time for the activation may be configured as N DRX cycles, where N is configurable (e.g., via higher layer signaling). FIG. 6 shows a schematic diagram of the effective time for the activation of the timer according to one embodiment of the present disclosure. In the embodiment shown in FIG. 6, N is configured / defined as 2. In FIG. 6, the timer is activated in the first DRX cycle. Since N is 2, the effective time for the activation of the timer is two DRX cycles. Therefore, the timer is activated in both the first and second DRX periods in FIG. 6.

[0094] In some embodiments, if the UE's time window / timer is not activated, the UE enters the drx-off state when the onDurationTimer and / or inactivityTimer expire or when it receives an associated MAC CE indication.

[0095] In some embodiments, the indication of whether to activate a time window / timer associated with a period may be implicit, i.e., the UE decides to activate the timer when certain conditions are met / met.

[0096] In some embodiments, the conditions associated with the implicit instruction include at least one of the following: The UE does not successfully detect a PDCCH with a CRC scrambled by a new radio network temporary identifier (RNTI) until the onDurationTimer and / or the inactivityTimer expire; -onDurationTimer expires and inactivityTimer does not start; - the inactivityTimer expires and exceeds the beginning of the time window; There is a PDCCH monitoring opportunity for SPS / CG activation / deactivation within the time window.

[0097] In some embodiments, the new RNTI is assigned by RRC signaling. In some embodiments, the new RNTI value associated with the period may be represented in 16 bits.

[0098] In some embodiments, the new RNTI indicates the use of a (characteristic of XR, e.g., quasi-periodic traffic) specific transmission. For example, if a new-RNTI is configured, a DCI CRC scrambled using the new-RNTI is used as an indication of (XR) specific traffic. In some embodiments, the new RNTI is used to scramble the cyclic redundancy check (CRC) of a DCI used for DCI monitoring of XR traffic / transmissions (or for characteristics of XR, e.g., quasi-periodic traffic).

[0099] In one example, the UE performs PDCCH monitoring within a time window and / or when a timer is running.

[0100] In some embodiments, the UE monitors the DCI format used for a particular service (e.g., an XR service and / or a cloud computing service). For example, the DCI format used for the particular service may include at least one of DCI format 1_0, DCI format 0_0, DCI format 1_1, and DCI format 0_1.

[0101] In some embodiments, the UE monitors a DCI format that is a CRC scrambled with an XR-specific RNTI (i.e., the new RNTI described above).

[0102] In some embodiments, the UE monitors the PDCCH when the inactivityTimer is restarted.

[0103] In some embodiments, an XR-specific RNTI indicates the use of a specific transmission (characteristic of XR, e.g., quasi-periodic traffic). In one embodiment, if an XR-specific RNTI is configured, a DCI with a CRC scrambled by the XR-specific RNTI is used to indicate XR traffic / transmission.

[0104] In some embodiments, the XR-specific RNTI is used to scramble the CRC of the DCI used for DCI monitoring of XR traffic / transmissions (or for characteristics of XR, such as quasi-periodic traffic).

[0105] In one example, the UE activates a new period of active time. In some embodiments, the period / window is defined as a new period of active time (e.g., DRX on period). The BS indicates whether to activate the associated timer via DCI, MAC CE, or reference signal. In one embodiment, the validity time of the activation indication includes N DRX periods, where N is configurable.

[0106] In some embodiments, a new active period is configured and the UE determines whether to activate the timer if one of the following conditions is met: - the UE does not monitor a PDCCH with a CRC scrambled by the new-RNTI until the onDurationTimer and / or the inactivityTimer expire; -onDurationTimer expires and inactivityTimer does not start; - the inactivityTimer expires and exceeds the beginning of the time window; There is a PDCCH monitoring opportunity for SPS / CG activation / deactivation within the time window.

[0107] In some embodiments, the UE performs PDCCH monitoring for XR traffic transmissions in the new active period.

[0108] For example, the UE monitors DCI formats used for XR, such as DCI format 1-0, DCI format 0-0, DCI format 1-1, and DCI format 0-1. Alternatively or additionally, the UE monitors DCI formats that may be CRC-scrambled with an XR-specific RNTI (i.e., a new RNTI).

[0109] In some embodiments, the new active period may be implemented by extending the onDurationTimer, i.e., during the new active period, the UE performs the same behavior as that associated with the onDurationTimer.

[0110] D. Activating PDCCH monitoring In some embodiments, if the UE does not successfully detect a PDCCH with a CRC scrambled by the new RNTI until the onDurationTimer and / or the inactivityTimer expire, the UE starts or reactivates the inactivityTimer after the time the onDurationTimer expires.

[0111] In some embodiments, if the UE does not successfully detect a PDCCH with a CRC scrambled by the new RNTI until the onDurationTimer or the inactivityTimer expires, the UE reactivates the inactivityTimer after the inactivityTimer expires.

[0112] In some embodiments, if the onDurationTimer expires and the inactivityTimer does not start, the UE starts the inactivityTimer in the next slot or 1 millisecond after the onDurationTimer expires.

[0113] In some embodiments, the new RNTI is assigned by RRC signaling. In some embodiments, the new RNTI value associated with the period may be represented in 16 bits.

[0114] In some embodiments, the new RNTI indicates the use of a (characteristic of XR, e.g., quasi-periodic traffic) specific transmission. For example, if a new-RNTI is configured, a DCI CRC scrambled using the new-RNTI is used as an indication of (XR) specific traffic / transmission. In some embodiments, the new RNTI is used to scramble the cyclic redundancy check (CRC) of a DCI used for DCI monitoring of XR traffic (or for a characteristic of XR, e.g., quasi-periodic traffic).

[0115] The operation / mechanism on the BS side is shown below. A. Higher Layer Signaling Indication In some embodiments, the BS (e.g., gNB) transmits higher layer signaling associated with the time window to the UE. The higher layer signaling may be RRC signaling (e.g., "XR-r18"). The RRC signaling may comprise one bit to indicate the presence of XR-specific configuration and / or to enable related functionality of the network.

[0116] In some embodiments, higher layer signaling is configured per UE, per bandwidth portion, and / or per cell.

[0117] B. Specific RRC Configurations In one example, the BS transmits specific RRC signaling to configure a specific configuration of parameters, e.g., in the time domain. In one embodiment, the RRC signaling is transmitted for DRX operation / configuration, and more specifically, to configure time domain parameters associated with the DRX operation / configuration.

[0118] In some embodiments, the UE-specific RRC signaling is configured per UE. The design of the RRC configuration from the BS is similar to the design of the RRC configuration of the UE. Therefore, for the design of the RRC configuration of the BS, you can refer to the above section B of the UE.

[0119] C. PDCCH Transmission in Time Window In some embodiments, the BS (e.g., gNB) sends signaling to the UE to indicate to the UE whether to activate the configured time window / timer.

[0120] In some embodiments, the indication includes a DCI, a DCI format, a DCI bit field, a MAC CE, or a reference signal. In one embodiment, the DCI format may be a UE-specific DCI format. In one embodiment, the DCI format is transmitted during a running onDurationTimer or a running inactivityTimer, the first PDCCH opportunity after expiration of the onDurationTimer, or a DRX off period.

[0121] In some embodiments, the DCI may be DCI format 2_x or have the same format as DCI format 2_6 and further include an indication of whether to activate a time window / timer. In one embodiment, the DCI includes a bit field indicating (1) whether to activate a time window / timer and / or (2) the duration of the time window / timer. In one embodiment, the bit field may include two or three bits. In one embodiment, the duration and whether to activate the time window are indicated together. In another embodiment, the bit field indicates the duration of the time window, and the length of the duration can be one of several candidate values. For example, the candidate values ​​for the length of the duration can be ½, ⅓, or ¼ of the length of the configured onDurationTimer.

[0122] In some embodiments, the UE receives a MAC CE that indicates whether to activate a time window / timer.

[0123] In some embodiments, the UE receives a reference signal that indicates whether to activate a time window / timer. The reference signal may be an SRC, a CSI-RS, a PN sequence, or a ZC sequence.

[0124] In one example, the validity time of the instruction may also be configured. In some embodiments, the validity time of the timer activation may be configured / defined. For example, the validity time refers to the number of DRX cycles during which the indication of whether to activate the time window / timer is valid. The validity time of activation may be configured as N DRX cycles, where N is configurable (e.g., via higher layer signaling). In one embodiment, the network reuses legacy PDCCH monitoring that skips the SSSG with an extension of the value range until the DRX off time for the purpose of saving power.

[0125] For example, a denser search space set is used for PDCCH monitoring in a time window / timer.

[0126] In one embodiment, the BS indicates a PDCCH monitoring skip / SSSG in the new DRX cycle. Figure 7 shows a schematic diagram of a PDCCH monitoring skip / SSSG according to one embodiment of the present disclosure. In Figure 7, the gNB indicates a PDCCH monitoring skip / SSSG in the new cycle, which includes the configured time window for PDCCH monitoring in the original DRX off period. In one embodiment, dynamic change of the periodicity of the search space set can be configured for monitoring in the time window.

[0127] In one embodiment, the BS configures a time window, and if the time window is configured before the onDurationTimer starts, the UE monitors the PDCCH within the time window. For example, the UE monitors the PDCCH within the time window if the time window is configured for several slots before the onDurationTimer starts. Figure 8 shows a schematic diagram of a time window according to one embodiment of the present disclosure. In Figure 8, the BS configures the time window several slots before the onDurationTimer starts (i.e., before the next DRX-on period). Therefore, in this embodiment, the UE monitors the PDCCH within the time window.

[0128] In one embodiment, only slots with even or odd numbers / indexes are used for PDCCH monitoring within the time window.
