[0001] Embodiments of the present application relate to the field of communication technology. BACKGROUND

[0002] Extended Reality (XR, eXtended Reality) refers to all real and virtual combined environments and human-machine interactions produced by computer technology and wearable devices. XR is a general term for different types of reality. XR includes AR, MR, VR, and other representative forms and mixed cross fields. Different application fields of XR include, for example, entertainment, medical care, education, etc.

[0003] Virtual Reality (VR, Virtual Reality) is a rendered version of the published visual and audio scene. When the observer or user moves within the limits defined by the application, the rendering aims to simulate the visual and auditory sensory stimuli of the real world as naturally as possible.

[0004] Augmented Reality (AR, Augmented Reality) refers to providing additional information or artificially generated items or content overlaid on the user's current environment.

[0005] Mixed Reality (MR, Mixed Reality) is an advanced form of AR, in which some virtual elements are inserted into a physical scene, with the aim of providing an illusion that makes people feel that these elements are part of the real scene. 5G technology is studying key issues, solutions and conclusions to support advanced media services, such as High Data Rate Low Latency (HDRLL) services, Augmented Reality (AR) / Virtual Reality (VR) / Extended Reality (XR) services, and haptic / multi-modal communication services. The goals include enhanced functions related to Radio Resource Management (RRM) measurement gaps or wireless resource management measurement restrictions.

[0006] Measurement gaps (MG) can affect scheduling delays and affect the performance of XR.

The above technical scheme cannot be considered as known to those skilled in the art merely because it is described in the background section of the present application.

[0008] SUMMARY

[0009] In the current communication system, factors that cause limitations on the availability of terminal device scheduling include: radio resource management measurement, radio link monitoring measurement, beam failure detection, etc. In the process of scheduling limitation, the terminal device does not decode the physical downlink control channel (PDCCH), so it cannot be scheduled. These scheduling limitations result in higher scheduling latency.

[0010] The present inventor finds that, since most XR protocol data units need to be delivered within a time of millisecond order, the performance of XR is greatly affected by high scheduling latency, and due to the scheduling limitation, the latency-sensitive XR service may not meet the latency requirement, thereby affecting the performance of the XR service. How to be able to transmit and / or receive in the measurement gap or limitation caused by radio resource management measurement is a problem to be solved.

[0011] To solve at least one of the above problems or other similar problems, the embodiments of the present application provide a method, device and communication system for enhancing measurement gap, which make the terminal device perform transceiving operation in the gap or limitation caused by RRM measurement through indication, solve the problem of transmitting and / or receiving in the measurement gap or limitation caused by radio resource management measurement, and thus can better support XR service and improve the user experience of XR and media service.

[0014] perform transceiving operation based on the indication,

[0053] The following describes a scenario of an embodiment of the present application by way of example, but the present application is not limited thereto.

[0054] FIG. 1 is a schematic diagram of a communication system according to an embodiment of the present application, which schematically illustrates a case taking a terminal device and a network device as an example. As shown in FIG. 1, the communication system 100 can include a network device 101, a terminal device 102 and a terminal device 103. For simplicity, FIG. 1 only takes two terminal devices and one network device as an example for illustration, but the embodiments of the present application are not limited thereto.

[0055] In the embodiments of the present application, the network device 101, the terminal device 102 and the terminal device 103 can perform existing services or future implementable services transmission. For example, these services can include but are not limited to: enhanced mobile broadband (eMBB), massive machine type communication (mMTC), ultra-reliable and low-latency communication (URLLC) and related communication of reduced capability terminal devices, etc.

[0056] Among them, the terminal devices 102 and 103 can be in an RRC_IDLE state, or an RRC_INACTIVE state or an RRC_CONNECTED state, and the terminal devices 102 and 103 can also communicate with the network device 101. For example, taking the terminal device 102 as an example, the terminal device 102 can send data to the network device 101, or can perform data retransmission.

[0057] It is worth noting that FIG. 1 shows that the terminal device 102 and the terminal device 103 are both within the coverage of the network device 101, but the present application is not limited thereto. The terminal device 102 and the terminal device 103 can both be outside the coverage of the network device 101, or one of the terminal device 102 and the terminal device 103 is within the coverage of the network device 101 and the other is outside the coverage of the network device 101.

[0058] Embodiments of the first aspect

[0059] The embodiments of the present application provide a method for enhancing a measurement gap, applied to the terminal device 102.

[0060] FIG. 2 is a schematic diagram of the method for enhancing a measurement gap according to the embodiments of the first aspect. As shown in FIG. 2, the method for enhancing a measurement gap comprises the following steps.

[0061] Operation 201: receiving an indication sent by the network device 101, the indication being used to make the terminal device 102 perform a transceiving operation in one or more radio resource management (RRM) measurement gaps, wherein the indication is sent through downlink control information (DCI) in a physical downlink control channel (PDCCH); and

[0062] Operation 202: the terminal device 102 performs a transceiving operation based on the indication.

[0063] The embodiments of the present application enable the terminal device 102 to perform data transmission and / or reception in the gap or restriction caused by RRM measurement through the indication, thereby solving the problem of how to perform data transmission in a measurement gap, and thus better supporting XR and media service applications with high latency requirements.

[0064] In the present application, since the indication is sent through downlink control information (DCI), in the following description, “indicated by the indication (indicate / indicates / indicating)” is also referred to as “indicated by the downlink control information (DCI)”, and both have the same meaning.

[0065] In the present application, the indication of operation 201 is a dynamic indication, which can be an explicit indication, or can also be an implicit indication.

[0066] The following describes the indication manner of the dynamic indication, wherein: the following method 1 and method 2 correspond to the explicit indication, and the DCI can use 1_1, 1_0, 1_2, 0_2, etc. format; and the method 3 corresponds to the implicit indication.

[0067] Method 1:

[0068] In method 1, the skipping of a measurement gap is indicated by explicit indication in DCI.

[0069] The skipping of a measurement gap means that the pre-defined measurement operation is not performed in the originally configured measurement gap time. The skipping of a measurement gap can also be called cancelling of a measurement gap, deactivating of a measurement gap, dropping of a measurement gap, etc. Since the dynamic indication of skipping of a measurement gap is actually for one or more measurement gap occasions in the semi-statically configured measurement gap, the skipping of a measurement gap can also be called skipping of a measurement gap occasion.

[0070] In some examples, one bit information can be added in the DCI to indicate skipping of the first measurement gap occasion after the DCI. For example, the bit is 1 to indicate skipping of the first measurement gap occasion after the DCI, and the bit is 0 to indicate not skipping of the first measurement gap occasion after the DCI.

[0071] Wherein, the first measurement gap occasion after the DCI means the first measurement gap occasion starting after the last symbol time of the PDCCH carrying the DCI plus the first time length. The first time length can also be called minimum time offset or minimum time interval, etc. The first time length is set to enable the terminal device 102 to have time to perform decoding and other processing after receiving the PDCCH, so as to respond to the change operation of the measurement gap configuration.

[0072] In addition, the first measurement gap occasion after the DCI can also be defined as the starting time of the measurement gap occasion after the last symbol time of the PDCCH plus the minimum time offset, so that only the measurement gap occasion that has not started can be cancelled. That is, the DCI indicates skipping of the first measurement gap occasion starting after the last symbol time of the PDCCH carrying the DCI plus the first time length.

[0073] In the above example, the first time length is configured by the network device 101 through a radio resource control (RRC) message. For example, at least one field or parameter representing the first time length can be added in the measurement gap configuration information element (measGapConfig IE) in the measurement configuration information element (measConfig IE) in the radio resource control reconfiguration message (RRCReconfiguration). In addition, the first time length can also be predefined; or the first time length is one of different time lengths predefined according to the capability of the terminal device 102.

[0074] FIG. 3 is a schematic diagram of indicating skipping of a measurement gap occasion according to the first aspect.

[0075] In some examples, as shown in FIG. 3, the measurement gaps 403a and 403b are configured by the network through RRC signaling, with configuration parameters including a measurement gap repetition period (MGRP) 404, such as 40 ms, and a measurement gap length (mgl), a gap offset (gapOffset) indicating the start time of the gap.

[0076] Both of the two downlink control information (DCI) 401a and 401b in FIG. 3 contain information indicating to skip the RRM measurement gaps 403a and 403b. The first measurement gap opportunity 403a starts after a defined first time length 402a after the last symbol of the PDCCH carrying the downlink control information 401a, for example, the start time 405a, so it is skipped; the second measurement gap opportunity 403b starts at a time 405b before a second time length 402b after the second PDCCH carrying DCI, so it is not skipped and RRM measurement is still to be performed in the second measurement gap opportunity 403b. Here, the first time length 402a is equal to the second time length 402b. For example, in the scenario of FIG. 3, the first measurement gap opportunity 403a and the second measurement gap opportunity 403b correspond to the same configuration, so the first time length 402a is equal to the second time length 402b.

[0077] In some examples of Method 1, if the network device performs multiple measurement gap configurations, the periodic measurement gap opportunities can overlap in time, so a gap priority (gapPriority) can be configured to determine which measurement gap opportunity is skipped. When dynamically indicating to skip a measurement gap opportunity, only the measurement gap opportunity that has not been canceled is skipped. That is, the DCI is used to indicate to skip the first measurement gap opportunity that has not been canceled, starting after the last symbol time of the physical downlink control channel (PDCCH) carrying the downlink control information plus a first time length. The measurement gap opportunity that has not been canceled means that it has not been canceled based on the gap priority in the case of conflict with other measurement gap opportunities.

[0078] FIG. 4 is another schematic diagram of indicating to skip a measurement gap opportunity according to an embodiment of the first aspect, showing a case of multiple priority measurement gap configurations.

[0079] There are two measurement gap configurations in FIG. 4, the first measurement gap configuration includes 403a, 403b, and the second measurement gap configuration includes 406a, 406b, the first measurement gap configuration has higher priority than the second measurement gap configuration. The first measurement gap opportunity 403a of the first measurement gap configuration and the first measurement gap opportunity 406a of the second measurement gap configuration have time overlap (conflict), for example, time period 407a, so the first measurement gap opportunity 406a of the second measurement gap configuration is cancelled. If the downlink control information 401a indicates skipping the next measurement gap opportunity, the terminal device skips the first measurement gap opportunity 403a of the first measurement gap configuration in FIG. 4.

[0080] In some embodiments, after the terminal device 102 receives the indication (for example, DCI) through the low layer (for example, the physical layer) and determines the skipped measurement gap opportunity (for example, determines the skipped measurement gap opportunity according to the method shown in FIG. 3 or FIG. 4), the terminal device 102 submits the indication of skipping the measurement gap opportunity to the high layer of the terminal device 102, for example, the medium access control (MAC) layer. In addition, if the terminal device 102 receives the indication that the measurement gap opportunity does not need to be skipped, the physical layer does not need to inform the high layer (MAC layer). That is, the physical layer decides which measurement gap opportunity to skip.

[0081] In some examples, the process of the MAC layer handling the measurement gap can be enhanced as follows:

[0082] If the low layer indicates that the measurement gap opportunity is skipped, it is considered that the measurement gap opportunity is skipped or deactivated, so that the measurement activity in the measurement gap opportunity is not performed, and data transmission and reception is performed in the measurement gap opportunity.

[0083] In other examples, the process of the MAC layer handling the measurement gap can be enhanced using the following method:

[0084] In the activated measurement gap opportunity, in addition to the skipped measurement gap opportunity indicated by the low layer, the entity (for example, the MAC entity) of the high layer performs at least one of the following operations in one or more serving cells in the frequency range corresponding to the activated measurement gap opportunity configured by the measurement gap configuration information element (measGapConfig IE):

[0085] Not sending hybrid automatic repeat request (HARQ) feedback, not sending scheduling request (SR), not sending channel state information (CSI);

[0086] Not reporting Sounding Reference Signal (SRS);

[0087] Not transmitting data on Uplink Shared CHannel (UL-SCH) except for the payload of message 3 or message A.

[0088] If the random access response window (ra-ResponseWindow) or the random access contention resolution timer (ra-ContentionResolutionTimer) or the message B response window (msgB-ResponseWindow) is running, or a Layer 1 / Layer 2 triggered mobile (LTM) cell switch without random access (RACH-less) is ongoing in the terrestrial network, or a handover without random access is ongoing, then monitor the Physical Downlink Control CHannel (PDCCH); otherwise, do not monitor the PDCCH and do not receive on the Downlink Shared CHannel (DL-SCH).

[0089] In some other embodiments, after the terminal device 102 receives the indication of the downlink control information (DCI) through the physical layer, if it is indicated to skip a certain measurement gap opportunity, the indication is delivered to the higher layer (e.g., the MAC layer). That is, the MAC layer decides which measurement gap opportunity to skip. In this case, the process of the MAC layer handling the measurement gap can be enhanced as follows:

[0090] If the lower layer indicates that the next measurement gap needs to be skipped, it is considered that the first measurement gap starting after a first time length (e.g., a minimum time offset) is skipped or deactivated.

[0091] Method 2:

[0092] A time window is indicated by the DCI for skipping one or more measurement gap opportunities within the time window.

[0093] The time window can be indicated by a start time and an end time, or a start time and a time window length. The specific time can be indicated by a system frame number, a subframe number, a slot number, a symbol, or a time offset, or a start time offset and a time window length. The time offset refers to a time length after the last symbol time of the PDCCH carrying the DCI, for example, in milliseconds. The start time offset of the time window can be the minimum time offset of method 1; the end time offset of the time window is a time offset greater than the start time offset.

[0094] Similar to method 1, the minimum time offset can be configured by the network through an RRC message or predefined. The length of the time window can also be configured by RRC. In this way, only one bit of indication needs to be added in the DCI to indicate skipping of the originally non-canceled measurement gap opportunity within the time window configured after the last symbol time of the PDCCH carrying the DCI plus the minimum time offset. A bit of 1 indicates skipping of the measurement gap opportunity within the time window, and a bit of 0 indicates not skipping the measurement gap opportunity within the time window.

[0095] FIG. 5 is a schematic diagram of the DCI indicating a time window. As shown in FIG. 5, the DCI indicates the terminal device 102 to skip one or more measurement gap opportunities 603a, 603b within the time window 605.

[0096] For example, the time window 605 can be indicated by a start time 605a and an end time 605b, or by a start time 605a and a length of the time window 605. The start time offset of the time window 605 is indicated by 602.

[0097] In some examples, after the terminal device receives the indication of the DCI through the physical layer, if it is indicated to skip one or more measurement gap opportunities, and the skipped measurement gap opportunities are determined according to the above method, the indication of skipping of the one or more measurement gap opportunities is delivered to the upper layer (MAC layer). If the received indication is that the measurement gap opportunity does not need to be skipped, the physical layer does not need to notify the upper layer. That is, the physical layer decides which measurement gap opportunities to skip. The process of the MAC layer processing the measurement gap is enhanced as follows:

[0098] If the lower layer (for example, the physical layer) indicates that the measurement gap opportunity is skipped, it is considered that the measurement gap opportunity is skipped or deactivated, so that the measurement activity within the measurement gap opportunity is not performed, and data transmission and reception is performed in the measurement gap opportunity.

[0099] In some other examples, after the terminal device receives the DCI indication through the physical layer, if it is indicated to skip one or more measurement gap opportunities, the terminal device submits the indication to the high layer (MAC layer). That is, the MAC layer decides which measurement gap opportunities to skip. For example, using the new DCI bit indication, and using the RRC configuration of the minimum time offset and the time window length, the MAC layer processing of the measurement gap is enhanced as follows:

[0100] If the low layer indicates that the measurement gap needs to be skipped, and one or more measurement gaps and a time window are fully or partially overlapped, the start time of the time window is the minimum time offset after receiving the indication, and the time length of the time window is determined by the configured time window size, then the one or more measurement gaps are considered to be skipped or deactivated.

[0101] In addition, a coincidence threshold can be defined. When the overlapping part of the measurement gap and the time window (such as the overlapping ratio, the ratio of the overlapping time length to the measurement gap time length) exceeds a threshold, it is considered that they are overlapped in time, and the above cancellation (skipping) operation needs to be performed, otherwise the measurement gap is not cancelled. The coincidence threshold can be predefined or configured by RRC signaling.

[0102] Method 3:

[0103] In method 3, a data transmission or reception is scheduled by DCI on the time domain resource that overlaps with a measurement gap opportunity to implicitly indicate skipping the measurement gap opportunity.

[0104] That is, dynamic scheduling by DCI can be dynamic downlink scheduling (allocation) or dynamic uplink scheduling (granting). If the scheduled resource is fully or partially overlapped in time with the measurement gap opportunity, it is implicitly indicated to skip the measurement gap opportunity.
