Description

Further enhance DRX operation of XR and cloud games in mobile communications

The present invention relates generally to mobile communications, and, more particularly, to further enhancing discontinuous reception (DRX) operations of extended reality (XR) and cloud gaming in mobile communications.

Unless otherwise stated, the methods described in this section are not prior art to the claims listed later and are not considered prior art by inclusion in this section.

In wireless communications, such as mobile communications under the 3rd Generation Partnership Project (3GPP) specifications for fifth generation (5G) New Radio (NR), such as extended reality , XR) and cloud gaming, applications and services with strict latency and high bandwidth requirements are emerging and becoming more common. However, there are still some issues that need to be addressed. One of the issues relates to the mismatch between the DRX cycle and the quasi-periodic XR business. This is because traditional DRX cycle values do not match the periodicity (or quasi-periodicity) of typical XR services. Over time, the difference may increase, and the DRX on duration (referred to interchangeably in this article as "on duration") may be completely outside the jitter cycle (e.g., out of sync). Another question is about the jitter of XR business/cloud gaming, because the jitter of XR and cloud gaming business may be large (for example, [-4, +4] milliseconds). Even assuming that the DRX cycle mismatch problem is resolved, covering the entire jitter cycle with the on duration may have a large impact on the UE's power consumption. On the other hand, in the case where the on-duration is less than the jitter, some downlink (DL) data may be delayed until the next on-duration. Therefore, a solution is needed to further enhance the DRX operation of XR and cloud gaming in mobile communications.

The following summary is illustrative only and is not intended to be limiting in any way. That is, the following summary is provided to introduce the concepts, highlights, benefits and advantages of the novel and non-obvious technologies described herein.

It is believed that the aforementioned issues related to DRX cycle mismatch and XR and cloud gaming jitter can be avoided, reduced or otherwise mitigated according to various proposed solutions.

In one aspect, a method may involve the UE entering DRX mode during wireless communications. The method also involves the UE receiving a value for at least one DRX timer or an indication regarding transmission. The method also involves the UE controlling either or both of the at least one DRX timer and the at least one on-duration occasion in response to the reception.

Embodiments according to the present invention relate to various technologies, methods, solutions and/or solutions related to further enhancing DRX operations of XR and cloud games in mobile communications. According to the present invention, a plurality of possible solutions can be implemented individually or jointly. That is to say, although the solutions are described separately below, two or more of the possible solutions can be implemented in one combination or another combination.

Figure 1 shows a schematic diagram of an example network environment 100 in which various solutions or solutions proposed in accordance with the present invention are implemented. Figures 2 to 6 show examples of implementations of various solutions in the network environment 100 proposed according to the present invention. The following description of the various proposed solutions is provided with reference to Figures 1-6.

Referring to Figure 1, network environment 100 may involve a UE 110 in wireless communication with a RAN 120 (eg, a 5G NR mobile network or another type of network such as NTN). UE 110 may communicate wirelessly with RAN 120 via a base station or network node 125 (eg, eNB, gNB, or transmit and receive point (TRP)). RAN 120 may be part of network 130. In the network environment 100, as described below, the UE 110 and the network 130 (via the network node 125 of the RAN 120) can implement various solutions related to further enhancing DRX operation of XR and cloud gaming in mobile communications. It is worth noting that although various proposed solutions, options and methods may be described individually below, in actual applications, these proposed solutions, options and methods may be implemented individually or jointly. That is, in some cases, each or a plurality of the presented solutions, options, and methods may be implemented individually or separately. In other cases, some or all of the proposed solutions, options and methods may be implemented jointly.

Under the first proposed aspect according to the present invention, one or a plurality of operations may be performed or otherwise implemented with respect to the corresponding value of each DRX timer, for example, starting a duration timer (interchangeably referred to herein as are "OnDurationTimer" and "ODT"), inactivation timer (herein referred to interchangeably as "drx-InactivityTimer", "InactivityTimer" and "IAT"), assist-on duration timer (herein referred to interchangeably as "drx-InactivityTimer", "InactivityTimer" and "IAT") is "SecondaryOnDurationTimer" or "SODT") and the retransmission timer (referred to interchangeably in this document as "Retransmission Timer DL/UL" and "RT"). For example, the corresponding value of each of ODT, IAT, SODT and RT may be indicated by downlink control information (DCI) signaling in the physical downlink control channel (PDCCH) , where the DCI can be a scheduled DCI or a separate DCI. Alternatively or additionally, the corresponding value for each of ODT, IAT, SODT and RT may be indicated by a control element (CE) of the DL medium access control (MAC). Alternatively or additionally, the corresponding value for each of ODT, IAT, SODT and RT may be selected from a set of values from the radio resource control (RRC) configuration.

Alternatively or additionally, each of ODT, IAT, SODT and RT may have separate DL and UL values for DL and UL transmission. For example, when the PDCCH indicates a (new) DL transmission, the corresponding DL values for ODT, IAT, SODT and RT can be applied. Similarly, when the PDCCH indicates (new) UL transmission, the corresponding UL values for ODT, IAT, SODT and RT can be applied. Alternatively or additionally, the corresponding value for each of ODT, IAT, SODT and RT may be set to 0 for both DL and UL or individually. For example, the network can indicate that the IAT applies only to DL or UL transmissions. Alternatively or additionally, additional bit fields in the DCI for DL or UL transmission may indicate whether the corresponding value for each of ODT, IAT, SODT, and RT applies to DL transmission or UL transmission.

Alternatively or additionally, when using multiple (active) DRX configurations, updates to the DRX configuration (e.g., ODT/IAT/SODT/RT) may be applied to the current on-duration (e.g., where the PDCCH is received) On duration) corresponding DRX configuration or the currently activated DRX configuration (index). Alternatively or additionally, updates to a DRX configuration (eg, ODT/IAT/SODT/RT) may be applied to other DRX configurations. In this case, the index of the updated DRX configuration may be signaled in the DCI and/or MAC CE to apply. The index may be the same as the index signaled in the RRC configuration used to configure DRX.

Figure 2 shows an example scenario 200 according to the first proposed solution of the present invention. Referring to Figure 2, the DRX On Duration Timer (ODT) can be stopped when any one of a plurality of conditions is met. Such conditions may include, for example, but not limited to: (1) PDCCH is received and a new UL or DL transmission is indicated; (2) a new DL transmission is received (on the Physical Downlink Shared Channel (PDSCH)) or a new UL or DL transmission is performed; UL transmission (on the physical uplink shared channel (PUSCH)); (3) Each time the DRX inactivation timer (IAT) is turned on. Additionally, the Secondary On Duration Timer (SODT) may be turned on only for the first PDCCH/data arriving during the On Duration, but unlike the inactivation timer, the SODT will not be turned on again for subsequent data arrivals. Additionally, the UE 110 may be in active time (eg, monitoring the PDCCH) while the SODT is running. It is worth noting that the condition for UL transmission may be used in the case where the overlay network 130 is sending an unsolicited dynamic grant (DG) to the UE 110 . The UL grant may instruct the UE 110 to stop monitoring the PDCCH for the current on duration.

Under the second proposed solution according to the present invention, in the case where an on-duration group is defined and the UE stops ODT and/or skips on-duration opportunities in the current group (for example, when the PDCCH indicates that a new UL or DL transmission), you can start another timer (such as SODT) after stopping ODT itself. For example, SODT can be turned on only for the first PDCCH/data arriving during the current turn-on duration group (but unlike IAT, is not turned back on for subsequent legal entity data). Furthermore, the same conditions as those described above with respect to the first proposed scheme can be applied to the parameters of the turn-on duration group (e.g., the values of ODT/IAT/SODT/RT) (e.g., they can be determined by the CE of the DCI or DL MAC to indicate, to select from a set of values for RRC configuration, and may include separate values for UL and DL or be set to 0).

Figure 3 shows an example scenario 300 according to the second proposed solution of the present invention. Referring to Figure 3, DRX on duration groups can be defined in a new way. For example, UE 110 may skip on-duration occasions in the current group and/or may stop ODT. Additionally, SODT can be started after stopping ODT. SODT can be turned on when the first PDCCH/data arrives during the current turn-on duration group (without restarting for subsequent data).

Under the third proposed solution according to the present invention, when a new timer (for example, SODT) is started after stopping the ODT, the running duration of the SODT can be limited to the end of the original ODT (for example, when the original ODT expires Stop SODT). Additionally, the duration of the SODT may depend on the arrival timing of the first material or the first PDCCH (eg, if the first material/PDCCH is received before time T0, the value SODT_0 is applied, otherwise a value SODT_1 different from SODT_0 is applied). It should be believed that since the scheduling is delayed until the end of the original ODT, the proposed scheme can improve the energy saving of the UE.

Figure 4 shows an example scenario 400 according to the third proposed solution of the present invention. Referring to Figure 4, when a PDCCH is received and a new UL or DL transmission is indicated, the original ODT may be stopped. Additionally, SODT can be turned on (and optionally, IAT can be turned on or back on). SODT may be stopped upon expiration of the original ODT timer for the current on duration of the PDCCH being received.

In the fourth proposed solution according to the invention, the behavior according to the above proposed solution may depend on one or a plurality of conditions. Under the proposed scheme, when a PDCCH indicating a new UL transmission (eg, UL grant) is received, the behavior according to the above proposed scheme may depend on a logical channel (LCH), where the LCH may be Or use UL permission to send or multiplex in a transport block (TB) (e.g., based on LCH restrictions). For example, IAT may or may not be enabled where the UL grant can be used to send material from the LCH subset. In addition, if the data is only available on a specific LCH, IAT does not need to be enabled. Additionally, IAT can be turned on where the data is only available on any LCH with specific settings. In addition, IAT can be disabled for gesture and/or control information, but can be enabled for other data (for example, Hypertext Transfer Protocol (HTTP) and/or File Transfer Protocol (FTP) services) . Under the proposed scheme, the behavior according to the above proposed scheme may depend on some indication within the PDCCH or DCI or the nature of the PDCCH or DCI. For example, the indication may include DCI or PUSCH or PDSCH duration in DCI format. It is worth noting that the above conditions/options are not mutually exclusive.

In view of the above, under various proposed aspects in accordance with the present invention, a method may involve indicating the corresponding value of each of one or a plurality of ODT, IAT, SODT and RT via DCI and/or MAC CE. Additionally or alternatively, the DRX timers for UL and DL transmissions may have these values (eg, the values of IAT and/or SODT) set separately (eg, set to 0). Additionally or alternatively, ODT may be stopped, and optionally other on-duration opportunities within the same on-duration group may be skipped, while a new timer may be started when a PDCCH indicating a new DL/UL transmission is received (e.g., SODT), and while the SODT is running, the PDCCH can be monitored. Additionally or alternatively, the expiration time of the SODT may be limited to the expiration time of the original ODT, or the value of the SODT may be set based on when the PDCCH for a new DL/UL transmission is received. Additionally or alternatively, the corresponding value of each of one or more DRX timers (eg, ODT, IAT, SODT, and RT) and/or the behavior of the DRX timer may be determined based on the LCH, where the LCH may be Transmitted in TB or multiplexed in TB.
