Configuring authorization operations

Abstract

Embodiments of the present disclosure relate to CG operations. In one aspect, a first device receives a first CG configuration and a second CG configuration from a second device. The first CG configuration is associated with a second CG configuration. If the first device determines that the set of occasions associated with the first CG configuration will be deactivated within the time period, the first device activates the second CG configuration. In this manner, fast reactivation of the CG configuration may be achieved, and communication latency may be reduced.

Examples of such functions include boot server functions and / or home subscriber servers, which may be implemented in the user equipment device by providing software to the user equipment device that is configured to cause the user equipment device to perform from the perspective of these functions / nodes.

[0040] XR refers to all combined real and virtual environments and associated human-computer interactions generated by computing and wearable devices. XR encompasses representative modalities such as augmented reality (AR), mixed reality (MR), and virtual reality (VR), as well as areas intervening between them. The main XR-related video service characteristics in the uplink (UL) can be summarized as follows: non-integer periodicity (e.g., 16.6ms for 60fps); packet delay budget (PDB) requirements, with 30ms as the baseline and 10ms and 15ms as options; and a varying video frame size based on a truncated Gaussian distribution, averaging 20.8kByte for 60fps and 10Mbit / s. In addition to video in the UL, gesture or control information can also be transmitted, with the following key characteristics: a periodicity of 4ms; a strict PDB requirement of 10ms; and a frame size of 100 bytes.

[0041] Recently, efforts towards capacity enhancement have been proposed, such as multiple CG physical uplink shared channel (PUSCH) transmission opportunities within a period of a single CG PUSCH configuration, and dynamic indication of unused CG PUSCH opportunities based on uplink control information (UCI) by the user equipment (UE).

[0042] As is well known, scheduling in UL can be achieved by adopting CG. For CG-based scheduling, parameters are configured via radio resource control (RRC) messages. The actual UL grant can be configured via RRC (type 1) or can be provided via the physical downlink control channel (PDCCH), for example, addressed to the configured scheduling radio network temporary identifier (CS-RNTI) (type 2). The main features of the New Radio (NR) Release 16 UL CG are: UL radio resources are configured for the UE to send one transport block (TB) with a regular time periodicity; the periodicity is: 2, 7, n*14 symbols, where the range of n depends on the configured subcarrier spacing (SCS); up to 12 CG configurations per bandwidth part (BWP) (configured via RRC signaling).

[0043] The motivation for the CG enhancement is the large and variable video sizes in the UL, which in many cases requires sending more than one time slot. For some XR applications such as AR, there can be different services in the UL: (i) gesture or control every 4ms, (ii) video every 16.67ms for 60fps. The PDB for gesture or control is equal to 10ms, and the PDB for UL video is 30ms, with options of 10ms or 15ms. It is very likely that gesture or control in the UL can be sent using CG resources to meet the PDB requirements.

[0044] Whenever video and gestures are sent in the UL, different CG configurations may be required: CG configuration 1 is used for video with periodicity close to the video periodicity and a large TB size, or for video with multiple CG opportunities per time period; CG configuration 2 is used for gestures, for example, once every 4ms, with a small TB size (e.g., 100 bytes).

[0045] As described above, if the CG resources associated with the CG configurations conflict with each other, only one CG configuration can be used for transmission, and the other CG configurations can be indicated as not required. If the user indicates to cancel certain CG opportunities and associated services, the valid CG resources will not be used for service transmission.

[0046] In view of this, an embodiment of the present disclosure provides a solution for communication of CG operation to overcome the above and other potential problems. In this solution, CG configurations can be associated with each other. If a set of timings associated with one of the CG configurations is deactivated within a time period, the other CG configurations can be assumed to be activated within the time period. If one of the CG configurations is used, the other CG configurations can be assumed to be deactivated.

[0047] In other words, when two or more CG configurations collide and only one CG configuration is selected to transmit data, the other CG configuration(s) may be deactivated in N time slots while the collision persists. If the network device receives an indication from the terminal device of a certain opportunity to deactivate the selected CG configuration for carrying data of a previously deactivated (e.g., due to a collision) CG configuration, the network device and the terminal device regard the indication as a trigger to reactivate the previously deactivated CG configuration(s).

[0048] In this way, a CG configuration can be implicitly activated or deactivated based on the terminal device's use of at least one of the other CG configurations. Therefore, rapid reactivation of the CG configuration can be achieved and communication latency can be reduced.

[0049] The principles and implementations of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0050] Figure 1 1 illustrates a schematic diagram of an example communication environment 100 in which some embodiments of the present disclosure may be implemented. Figure 1 As shown, the communication environment 100 may include a first device 110 and a second device 120 serving the first device 110. For illustration, the first device 110 is shown as a terminal device, and the second device 120 is shown as a network device.

[0051] It should be understood that Figure 1The number of first devices and second devices in the communication environment 100 is given for illustration purposes only and does not represent any limitation to the present disclosure. The communication environment 100 may include any suitable number of first devices and / or second devices suitable for implementing the present disclosure.

[0052] For illustrative purposes only, and not intended to limit the scope of the present disclosure, some embodiments will be described in the context of first device 110 being a terminal device and second device 120 being a network device. It should be understood that in other embodiments, first device 110 may be a network device, and second device 120 may be a terminal device. In other words, the principles and spirit of the present disclosure can be applied to both uplink and downlink transmissions.

[0053] like Figure 1 As shown, the first device 110 and the second device 120 can communicate with each other via a wireless communication channel. The communication within the communication environment 100 can comply with any suitable standard, including but not limited to LTE, LTE evolution, advanced LTE (LTE-A), wideband code division multiple access (WCDMA), code division multiple access (CDMA) and global system for mobile communications (GSM) etc. In addition, the communication can be performed according to any generation of communication protocols currently known or to be developed in the future. The example of the communication protocol includes but is not limited to first generation (1G), second generation (2G), 2.5G, 2.75G, third generation (3G), fourth generation (4G), 4.5G, fifth generation (5G) or sixth generation (6G) communication protocol.

[0054] In some embodiments, the second device 120 may send one or more CG configurations to the first device 110. One or more CG configurations may be activated or deactivated for service transmission. A CG configuration may be associated with one or more services.

[0055] In some scenarios, CG configurations may conflict with each other, and only one CG configuration is used for transmission. One straightforward possibility is to select a CG configuration with a larger TB size to carry conflicting services, such as video and gestures. In the absence of the need for other CG configurations, the conflict may last for N consecutive time slots. Figure 2A FIG200A illustrates an example scenario of a conflict of CG configurations in which embodiments of the present disclosure may be implemented. In this example, it is assumed that the time division duplex (TDD) structure is DDDSU, and gestures arrive every 4 ms and video frames arrive every 16.67 ms. Figure 2A As shown, gesture and video arrive. CG1 is configured for video transmission, and CG2 is configured for gesture transmission. CG1 and CG2 in some UL time slots collide with each other.

[0056] Since the network device knows the number of consecutive time slots used for CG1 (denoted as N), the network device can deactivate CG2 resources within N consecutive time slots. Figure 2B FIG200B is illustrated, which shows an example scenario in which embodiments of the present disclosure may be implemented, where traffic is transmitted using one CG configuration (e.g., CG1) under conflicting CG configurations. In this example, it is assumed that the TDD structure is DDDSU and SCS=30kHz. Figure 2B As shown, CG1 and CG2 conflict with each other. After the gesture and video arrive, the gesture and video are sent via CG1, and CG2 is deactivated within 3 UL time slots.

[0057] However, video frames in the UL can be of variable size and therefore the exact number of resources or time slots required cannot be predicted. Therefore, a dynamic indication of the unused CG PUSCH opportunities was agreed upon. The key benefit of the dynamic indication is the ability to reallocate unused UL resources. That is, the terminal device can indicate that a certain opportunity or opportunities are not required and the network equipment can consider these resources for other users. For example, the terminal device can Figure 2B UCI is sent in UL timeslot 210 in , to indicate that UL timeslot 220 is not needed. In this case, the next posture will have no valid CG resources because CG2 is implicitly disabled within 3 timeslots in this example.

[0058] Therefore, the embodiment of the present disclosure provides a solution for communication of CG operation. Figure 3 Describe in more detail.

[0059] Figure 3 FIGURE 1 illustrates a flow diagram showing a communication process 300 for CG operations according to some embodiments of the present disclosure. For discussion purposes, reference will be made to Figure 1 Describe process 300. Process 300 may involve Figure 1 A first device 110 and a second device 120 are shown. Assume that the first device 110 is served by the second device 120.

[0060] like Figure 3 As shown, the second device 120 can send 310 a first CG configuration and a second CG configuration to the first device 110. The first CG configuration is associated with the second CG configuration. In other words, the first CG configuration and the second CG configuration are linked or paired. It should be understood that the present disclosure does not limit the number of first CG configurations and second CG configurations. In other words, the second device 120 can send multiple CG configurations, and multiple CG configurations can be linked or paired. For convenience, the following description is given by taking the first CG configuration and the second CG configuration as an example.

[0061] In some embodiments, the first CG configuration may be associated with the first business, or may be associated with both the first business and the second business. That is, the first CG configuration may be used for the first business or for both the first business and the second business. The second CG configuration may be associated with the second business. That is, the second CG configuration may be used for the second business. It should be understood that each CG configuration in the first CG configuration and the second CG configuration may be associated with multiple businesses or any business, and the present disclosure does not limit the number and type of businesses.

[0062] In some embodiments, the first CG configuration may overlap with the second CG configuration. For example, the first CG configuration may completely overlap with the second CG configuration. In another example, the first CG configuration may partially overlap with the second CG configuration. Alternatively, the first CG configuration may not overlap with the second CG configuration.

[0063] Continue to refer Figure 3 , the first device 110 may determine 320 that a set of opportunities associated with the first CG configuration will be deactivated within a time period. In some embodiments, the set of opportunities may be all opportunities associated with the first CG configuration. In some embodiments, the set of opportunities may be a portion of the opportunities associated with the first CG configuration. In some embodiments, the time period may be any suitable number of consecutive time slots. It should be understood that any other suitable time unit is also feasible.

[0064] In some embodiments where the first CG configuration is associated with the first service and the second CG configuration is associated with the second service, if the first CG configuration and the second CG configuration overlap, the first device 110 can determine that a set of opportunities for carrying the first service and the second service during the overlapping period of the first CG configuration and the second CG configuration will be deactivated.

[0065] In some embodiments where a first CG configuration is associated with a first service and a second CG configuration is associated with a second service, the first device 110 may determine that a set of opportunities associated with the first CG configuration will be deactivated if the size of the cache associated with the first service is lower than a first threshold size.

[0066] For example, the first device 110 is configured with two CG configurations: CG#1 sized for UL video frames, and CG#2 sized for UL posture information. The first device 110 can use CG#1 to send UL data and any other additional data related to the UL video frame. When the first device 110 has completed video frame transmission and there is no more relevant data in the UL buffer (e.g., the size of the buffer is below a first threshold size), the first device 110 can deactivate CG#1 and use CG#2 to send, for example, UL posture information.

[0067] This results in CG#1 being assumed to be implicitly unused within N time slots (where N is configurable) or when video data is available for transmission. In some embodiments, the second device 120 may know that CG#1 is being used based on the UCI indication. In some embodiments, the second device 120 may know that CG#1 is being used based on the timing configured for CG#1. For example, when there are multiple opportunities per configured time period, the first opportunity of the time period is always assumed to be used. In another example, multiple (e.g., configurable) transmissions based on CG#2 are required to cause implicit disabling of CG#1.

[0068] In some embodiments, a CG configuration may be associated with a particular UL buffer state, and implicit disabling or enabling of the CG configuration may be based on the contents of a buffer status report (BSR). In some embodiments, the first device 110 may determine that a set of opportunities associated with the first CG configuration is to be deactivated if the buffer state of a logical channel group (LCG) associated with the first CG configuration in the BSR is below a threshold state. For example, when the first device 110 reports a BSR and the reported buffer state of an LCG containing logical channels (LCHs) that are allowed to utilize the CG (e.g., according to an allowed CG list) is below a configured threshold (e.g., a threshold state), certain (e.g., larger UL data rate) CG configurations are assumed to be implicitly disabled, while other (e.g., smaller UL data rate) CG configurations are assumed to be enabled.

[0069] Alternatively or additionally, if the buffer size reported in the BSR is above a second threshold size and the first CG configuration corresponds to a data rate below a threshold rate, the first device 110 may determine that a set of opportunities associated with the first CG configuration is to be deactivated. For example, when the buffer size reported in the BSR exceeds a certain configured threshold (e.g., a second threshold size), certain (e.g., smaller UL data rate) CG configurations are assumed to be implicitly disabled, while other (e.g., larger UL data rate) CG configurations are assumed to be enabled. In another example, implicit activation may result if the buffer size reported in the BSR exceeds or falls below a configured threshold for a given time.

[0070] Continue to refer Figure 3 , based on deactivating the set of opportunities associated with the first CG configuration, the first device 110 may activate 330 the second CG configuration. In some embodiments, the first device 110 may send 331 an indication to the second device 120 that the set of opportunities will be deactivated within the time period. In other words, the first device 110 dynamically indicates that certain CG resources are not being used. In this case, the first device 110 may activate 332 the linked or paired CG configuration (e.g., the second CG configuration).

[0071] In some embodiments, if the first CG configuration is deactivated, the first device 110 may activate a second CG configuration. In some embodiments in which the first CG configuration is associated with a first service, the first device 110 may activate the second CG configuration if no retransmission is scheduled for the first service associated with the first CG configuration during the time period. For example, the first device 110 is configured with two CG configurations: CG#1 sized for UL video frames, and CG#2 sized for UL posture information. If no retransmission is scheduled for the PUSCH carrying UL video during time X or via a PDCCH-based activation indication, the first device 110 may activate CG#2 for the expected UL posture information transmission.

[0072] In some embodiments, if a first CG configuration that overlaps with a second CG configuration is reactivated, the first device 110 may use the first CG configuration for transmission and deactivate the second CG configuration during the overlapping period of the first CG configuration and the second CG configuration. For example, the first device 110 is configured with two CG configurations: CG#1 sized for UL video frames, and CG#2 sized for UL posture information. If CG#1 that overlaps with CG#2 is reactivated (e.g., due to a retransmission), CG#2 is not activated, and CG#1 sends both posture and video during the overlapping period.

[0073] Continue to refer Figure 3 , the first device 110 may determine 340 that a first CG configuration is used for transmission.

[0074] In some embodiments, if the first CG configuration has a higher priority than the second CG configuration, the first device 110 may determine that the first CG configuration is used for transmission. For example, it may be configured which linked CG configuration is prioritized, and when CG opportunities conflict, or only one of the linked CG configurations will be used within a duration (e.g., they are considered associated). When there is data transmission for a prioritized CG configuration, the first device 110 may select the prioritized CG configuration to construct a TB and indicate the use of one or more CG opportunities. Alternatively, when there are multiple opportunities per time period, the first opportunity within the time period of the high-priority CG configuration is always used. For associated opportunities, when the CG opportunity of the prioritized CG configuration is used, the non-priority CG configuration is automatically activated or used, and vice versa. Based on the indication, the second device 110 may know whether to use the prioritized CG configuration or the non-priority CG configuration, and may therefore allocate unused resources to other devices. In this case, only one indication is required for the linked CG configuration, and therefore there is no need to explicitly indicate the non-priority CG configuration.

[0075] In some alternative or additional embodiments, if the first CG configuration has more resources than the resources of the second CG configuration, the first device 110 may determine that the first CG configuration is used for transmission.In some alternative or additional embodiments, if the first CG configuration is associated with both the first service and the second service, and the second CG configuration is associated with the second service, the first device 110 may determine that the first CG configuration is used for transmission.

[0076] Continue to refer Figure 3 After determining that the first CG configuration is used for transmission, the first device 110 may deactivate 350 the second CG configuration. In some embodiments, the first device 110 may deactivate the second CG configuration for a duration. In some embodiments, the first device 110 may deactivate the second CG configuration within a set of overlapping opportunities between the first CG configuration and the second CG configuration.

[0077] Still refer to Figure 3 In some embodiments where the first CG configuration is associated with the first service and the second CG configuration is associated with the second service, the first device 110 may further receive 360 a third CG configuration for the second service from the second device 120. The third CG configuration is also associated with the first CG configuration. In some embodiments, the second CG configuration and the third CG configuration may have the same time-frequency resource allocation but different demodulation reference signal (DMRS) and media access control (MAC) configurations. It should be understood that this is merely an example and that the third CG configuration may be configured independently of the second CG configuration.

[0078] refer to Figure 3 , if the first traffic arrives during the time period (during which the set of opportunities associated with the first CG configuration will be deactivated), the first device 110 may send 370 the second traffic based on the third CG configuration. In some embodiments, after the transmission of the second traffic based on the third CG configuration, the first device 110 may activate 375 the first CG configuration while deactivating the second CG configuration and the third CG configuration.

[0079] After receiving the second traffic on the CG resources of the third CG configuration, the second device 120 may determine 380 that the first CG configuration is activated and the second CG configuration and the third CG configuration are deactivated. The second device 120 may send 385 hybrid automatic repeat request (HARQ) feedback for the reception of the second traffic to the first device 110. In some embodiments, after receiving the HARQ feedback, the first device 110 may activate 390 the first CG configuration while deactivating the second CG configuration and the third CG configuration.

[0080] For example, the first device 110 is configured with three CG configurations: CG#1 sized for UL video frames, and CG#2 and CG#3 sized for UL posture information. CG#2 is used as a normal CG to carry posture, and CG#3 is used only when the first device 110 needs to indicate that a larger grant is required while still conveying posture information. In this example, CG#1 has been indicated by the first device 110 as not to be used or assumed to be disabled within N time slots (for example, because the UL video frame has already been sent or the UL buffer is below a threshold). The first device 110 is using CG#2 to send posture information. If a video frame arrives at the UL buffer during the duration of N time slots, the first device 110 can send posture information in CG#3 to indicate that a larger grant needs to be activated. The first device 110 may need to indicate in some way that a previously deactivated UL video grant needs to be reactivated. Therefore, the first device 110 can use a special CG#3 to send posture, and thereby implicitly request activation of the large video grant CG#1.

[0081] This results in both the first device 110 and the second device 120 assuming that CG#1 is activated and that CG#2 and CG#3 are deactivated (e.g., implicitly). This assumption can be confirmed or applied when the second device 120 sends HARQ feedback for UL transmissions to the first device 110, or via an activation indication based on the PDCCH. If CG#1 is deactivated again or temporarily deactivated, CG#2 can be activated because CG#2 is the primary grant used only for posture information. CG#3 is only needed as an indication that a larger grant is needed.

[0082] So far, the communication process for CG operation has been described. Using process 300, fast reactivation of CG configuration can be achieved and communication latency can be reduced.

[0083] It should be noted that the above process 300 is merely an example and may have additional or fewer operations.It should also be noted that the operations of the above process 300 may be performed individually or in any suitable combination.

[0084] Corresponding to the above process, exemplary embodiments of the present disclosure also provide a communication method. Figure 4 FIGURE 4 is a flow diagram illustrating an example method 400 implemented at a first device according to some embodiments of the present disclosure. For discussion purposes, reference will be made to Figure 1 Method 400 is described.

[0085] At block 410 , the first device 110 receives a first CG configuration and a second CG configuration from the second device 120 , the first CG configuration being associated with the second CG configuration.

[0086] At box 420, the first device 110 determines that a set of opportunities associated with the first CG configuration are to be deactivated within a time period.

[0087] In some embodiments, if no retransmission is scheduled for the first service associated with the first CG configuration during the time period, the first device 110 may activate the second CG configuration. In some embodiments, if the first CG configuration is deactivated, the first device 110 may activate the second CG configuration.

[0088] In some embodiments, if the first CG configuration overlapping with the second CG configuration is reactivated, the first device 110 may use the first CG configuration for transmission and deactivate the second CG configuration during the overlapping period of the first CG configuration and the second CG configuration.

[0089] In some embodiments, the first CG configuration may be associated with the first service, and the second CG configuration may be associated with the second service. In some embodiments, if the first CG configuration and the second CG configuration overlap, the first device 110 may determine that a set of opportunities for carrying the first service and the second service during the overlapping period of the first CG configuration and the second CG configuration will be deactivated.

[0090] In some embodiments, if the size of the cache associated with the first service is below a first threshold size, the first device 110 may determine that a set of opportunities associated with the first CG configuration will be deactivated within the time period.

[0091] In some embodiments, if the cache status of the logical channel group associated with the first CG configuration in the cache status report is lower than a threshold state, the first device 110 can determine that the set of opportunities associated with the first CG configuration will be deactivated within the time period.

[0092] In some embodiments, if the cache size reported in the cache status report is higher than a second threshold size and the first CG configuration corresponds to a data rate lower than a threshold rate, the first device 110 can determine that a set of opportunities associated with the first CG configuration will be deactivated within the time period.

[0093] At block 430 , the first device 110 activates the second CG configuration.

[0094] In some embodiments, the first device 110 may send an indication to the second device 120 that the set of opportunities will be deactivated within the time period. In some embodiments, following transmission of the indication, the first device 110 may activate the second CG configuration.

In some embodiments, the first device 110 may determine that the first CG configuration is used for transmission and deactivate the second CG configuration within a set of overlapping opportunities between the first CG configuration and the second CG configuration.

[0096] In some embodiments, if the first CG configuration has a higher priority than the second CG configuration, the first device 110 may determine that the first CG configuration is used for transmission. In some embodiments, if the first CG configuration has more resources than the second CG configuration, the first device 110 may determine that the first CG configuration is used for transmission. In some embodiments, if the first CG configuration is associated with both the first service and the second service, and the second CG configuration is associated with the second service, the first device 110 may determine that the first CG configuration is used for transmission.

[0097] In some embodiments where the first CG configuration may be associated with the first service and the second CG configuration may be associated with the second service, the first device 110 may receive a third CG configuration for the second service from the second device 120, the third CG configuration being associated with the first CG configuration. If the first service arrives during the time period, the first device 110 may send the second service based on the third CG configuration. If HARQ feedback for the transmission of the second service based on the third CG configuration is received, or if the second service is sent based on the third CG configuration, the first device 110 may activate the first CG configuration and deactivate the second CG configuration and the third CG configuration. In some embodiments, the second CG configuration and the third CG configuration may have the same time-frequency resource allocation, but different demodulation reference signals and media access control configurations.

[0098] Using the method 400, the CG configuration can be quickly reactivated and the communication delay can be reduced.

In some embodiments, the second CG configuration and the third CG configuration may have the same time-frequency resource allocation but different demodulation reference signal and media access control configurations.
