Configuration grant enhancements

Abstract

An embodiment of the present disclosure relates to an extension of configuration grant (CG). An apparatus determines whether at least one resource within a predetermined time period is used for CG data transmission, and the at least one resource follows a target resource in the time domain. Based on the determination result, the apparatus transmits a notification on the target resource to a network apparatus, the notification indicating whether the at least one resource is used or canceled. In this way, the UE can notify the CG usage opportunity for each time period with little increase in signaling overhead. In some cases, the network can dynamically update the scheduling priority of the UE based on such notification.

[0003] XR-related data (e.g., video traffic, attitude control information) are characterized by variable size and non-integer periodicity. Such data is scheduled using configuration grants (CGs). In some XR applications, video frame sizes vary significantly, requiring multiple slots across multiple uplink (UL) CG opportunities to transmit XR-related data. However, due to data size variations, not all CG opportunities are necessarily used in one period. Therefore, improving resource utilization in CG transmission is necessary. Summary of the Invention

[0025] As used herein, the term "controller" refers to any entity / function / device / apparatus for control. In some embodiments, a controller is an apparatus used to implement domain orchestration, network optimization, network management functions, etc.

[0026] While the functionality described herein may be performed in fixed and / or wireless network nodes in various embodiments, in other embodiments it may be implemented in a user equipment device (e.g., a mobile phone, a tablet computer, a laptop, a desktop computer, a mobile IoT device, a fixed IoT device, etc.).

Examples of such functionality include a bootstrap server function or a home subscriber server, which are implemented by providing software to the user equipment device that configures the user equipment device to operate from the perspective of these functions / nodes.

[0027] The main characteristics of XR-related video traffic on UL can be summarized as follows: Non-integer periodicity (e.g., 16.67ms for 60fps) Packet Delay Budget (PDB) requirement, with a base value of 30 ms and optional values ​​of 10 ms or 15 ms Video frame sizes vary, averaging 20.8 kB at 60 fps and 10 Mbit / s, which follows a truncated Gaussian distribution.

[0028] In addition to UL video traffic, attitude / control information may be transmitted with the following key characteristics: Period: 4 ms Strict PDB Requests (10 ms) Frame size 100 bytes

[0029] As mentioned above, CG can be used to schedule UL data transmissions, including (but not limited to) XR related traffic. In CG based scheduling, parameters are configurable via RRC messages. The actual UL grant is configured via RRC for CG type 1 or provided via the Physical Downlink Control Channel (PDCCH) (destined to CS-RNTI) for CG type 2. The main characteristics of NR Rel-16 UL CG are: A UE is configured with UL radio resources for transmitting one transport block at regular time periods. A period contains 2, 7 or n*14 symbols, where the range of n depends on the configured SCS. Up to 12 CG configurations are possible per bandwidth portion (BWP), which can be configured via RRC signaling.

[0030] XR-related traffic may often be sent across multiple slots due to large variations in video size. For certain XR applications, such as AR, there may be varying amounts of traffic on the UL, such as (i) attitude / control information every 4 ms, and / or (ii) video traffic every 16.67 ms at 60 fps. The attitude / control information PDB may be 10 ms, and the UL video PDB may be 30 ms, with options for 10 ms or 15 ms.

[0031] To enhance XR, different types of CG configurations (e.g., one CG opportunity per period or multiple CG opportunities per period) are possible to transmit XR transmissions of various sizes. Furthermore, networks such as gNBs are expected to understand the utilization status of CG opportunities at the UE side. In this case, the gNB can allocate unused resources to other UEs.

[0032] According to embodiments of the present specification, a solution for CG transmission is provided, in which a UE can provide a notification indicating unused or used CG data transmission opportunities without additional signaling overhead. This notification is applicable to various CG configurations, such as one CG opportunity per period or multiple CG opportunities per period.

[0033] Based on the notification, the gNB can reuse the released resources for other transmissions. Furthermore, the scheduling priority of the UE can be dynamically updated based on whether the UE provides a notification and / or the number of unused resources indicated by the UE, thereby motivating the UE to provide such a notification to the gNB.

[0034] 1 illustrates an example communication environment 100 in which embodiments of the present disclosure can be implemented. The communication environment 100 is a communication network that supports various types of CG configurations, such as a single CG Physical Uplink Shared Channel (PUSCH) opportunity per CG transmission period or multiple CG PUSCH opportunities per CG transmission period. The communication network 100 includes a first device 110 and a second device 120.

[0035] The first device 110 may be, for example, a terminal device such as a UE. The second device 120 may be, for example, a network device that provides a service to the first device 110, such as a gNB. Thus, the first device 110 and the second device 120 can communicate with each other. Hereinafter, the first device 110 may also be referred to as a terminal device 110 or a UE 110. The second device 120 may also be referred to as a network device 120 or a gNB 120.

[0036] In some embodiments, the link from the second device 120 to the first device 110 is referred to as the downlink (DL), and the link from the first device 110 to the second device 120 is referred to as the uplink (UL). In the DL, the second device 120 is the transmitting (TX) device (or transmitter) and the first device 110 is the receiving (RX) device (or receiver). In the UL, the first device 110 is the TX device (or transmitter) and the second device 120 is the RX device (or receiver).

[0037] In some embodiments, UL transmissions from the first device 110 may be scheduled by the CG. Thus, in the context of these embodiments, such UL transmissions may also be referred to as CG data transmissions. The second device 120 may configure the first device 110 with a CG configuration. As previously mentioned, communication network 100 supports both a configuration in which one CG opportunity is configured per CG transmission period and a configuration in which multiple CG opportunities are configured per CG transmission period.

[0038] The first device 110 determines whether a slot or opportunity configured for UL transmission is to be canceled. In some cases, not all slots or CG opportunities are used for CG data transmission, for example, due to variable size of the CG data transmission. In this case, the first device 110 sends a resource utilization notification to the second device 120 to indicate one or more used or unused CG opportunities. This notification can be sent in either a dynamic or fixed manner, as described in more detail below.

[0039] 1 are merely illustrative examples and are not intended to imply any limitations. Communications network 100 may include any suitable number of devices configured to implement embodiments of the present disclosure. While not shown, it should be understood that one or more additional devices and connections may be disposed in communications network 100.

[0040] Communications in the communication environment 100 may be conducted according to any suitable communication protocol, including, but not limited to, cellular communication protocols such as first generation (1G), second generation (2G), third generation (3G), fourth generation (4G), fifth generation (5G), and sixth generation (6G), wireless local network communication protocols such as Institute of Electrical and Electronics Engineers (IEEE) 802.11, and / or other protocols now known or developed in the future. Further, communications may utilize any suitable wireless communication technology, including, but not limited to, code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), frequency division duplex (FDD), time division duplex (TDD), multiple input multiple output (MIMO), orthogonal frequency division multiplexing (OFDM), discrete Fourier transform spread OFDM (DFT-s-OFDM), and other technologies now known or developed in the future.

[0041] The embodiments of the present specification will be described in detail below with reference to the accompanying drawings.

[0042] Please refer to Fig. 2. Fig. 2 shows a signaling chart for CG transmission according to some embodiments of the present disclosure. As shown in Fig. 2, a process 200 includes a first device 110 and a second device 120. For illustrative purposes, the signaling flow 200 will be described with reference to Fig. 1.

[0043] In process 200, data transmissions from the first device 110 are scheduled based on the CG. To this end, the second device 120 configures a CG setting for the first device 110. In some embodiments, the CG setting is one CG PUSCH opportunity per CG transmission period. In other embodiments, the CG setting is multiple CGPUSCH opportunities per CG transmission period.

[0044] The first device 110 determines whether at least one CG opportunity within a predetermined time period will be used for CG data transmission. In the context of this specification, the term "CG opportunity" or "CG PUSCH opportunity" refers to a time resource configured for CG data transmission, which may have various sizes and types and may include equivalents with different names based on any suitable generation communication protocol and / or communication standard now known or developed in the future.

[0045] In some embodiments, the first device 110 can determine whether a future CG opportunity is needed. For example, the first device 110 can evaluate the status of the UL buffer and, based on the status, determine whether at least one future CG opportunity is needed.

[0046] In some embodiments, the first device 110 determines whether to use or not use a future CG opportunity based on whether the amount of data in the UL buffer has fallen below a UL buffer data volume threshold. For example, if the amount of data in the UL buffer is below a data volume threshold, the first device 110 determines to not use or cancel a future CG opportunity. On the other hand, if the amount of data in the UL buffer is not below the threshold, the first device 110 determines to use a CG event for CG data transmission. It should be understood that a particular threshold may also be suitable for indicating a UL buffer empty state.

[0047] The UL buffer threshold is used to evaluate whether a future CG opportunity is needed for CG data transmission. Additionally or alternatively, in some embodiments, the UL buffer threshold may be determined based on the size of a CG opportunity before the CG opportunity is marked as unused.

[0048] In some embodiments, the first device 110 determines whether to use or not use a future CG opportunity based, at least in part, on the validity period of the UL buffer data. In particular, the validity period of the UL buffer may be based on at least one of a PDB, a PSDB, a Packet Data Convergence Protocol (PDCP) discard timer, etc. If the validity period of the UL buffer data expires before the future CG opportunity, the first device 110 determines that the future CG opportunity is unnecessary and can release / cancel it. Conversely, if the validity period of the UL buffer data does not expire before the future CG opportunity, the first device 110 determines that the future CG opportunity should be utilized for transmitting the UL buffer data.

[0049] Additionally or alternatively, in some embodiments, the first device 110 may further consider the importance or priority of the protocol data unit (PDU) being transmitted to determine whether to use or leave a future CG opportunity unused.

[0050] Therefore, the first device 110 transmits a notification to the second device 120 indicating whether the at least one CG opportunity is used or canceled based on the determination result, the notification being transmitted on the target resource, and the at least one CG opportunity being transmitted in the time domain following the target resource.

[0051] In some embodiments, the predetermined period is at least one CG transmission period, or a sliding window starting from the target resource or the first number of resources immediately following the target resource in the time domain, as described below.

[0052] In some embodiments, this notification is conveyed via uplink control information (UCI). One example implementation is to set a bit in the UCI as the notification, where the bit is set to a first value (e.g., "1") to indicate the next applicable CG opportunity is to be canceled or unused, and is set to a second value (e.g., "0") to indicate that the next applicable CG opportunity is to be used.

[0053] Furthermore, in embodiments where multiple CG opportunities are configured per CG transmission period, if a one-bit indication in the UCI, for example indicating the next applicable CG opportunity in the next slot or the next CG opportunity within a slot, is unused or canceled, it also implicitly indicates that all subsequent opportunities within the same period are unused or canceled.

[0054] FIG. 3A illustrates a schematic diagram of an example UCI notification 300 according to some embodiments of the present disclosure. In the example of FIG. 3A, the CG configuration has three CG opportunities per CG period: CG1_1, CG1_2, and CG1_3. UCI1, transmitted in CG1_1, indicates the resource utilization status of the next upcoming opportunity. Specifically, UCI1 indicates whether the CG opportunity for CG1_2 is used or unused. All remaining CG opportunities within that CG period may be implicitly canceled. For example, if the notification of UCI1 cancels the next opportunity, it applies to CG1_3.

[0055] In some embodiments, if the CG configuration has a single CG opportunity per CG period, a one-bit notification can indicate that the next applicable CG opportunity is canceled. Figure 3B shows a schematic diagram of another example UCI notification 310 according to some embodiments of the present disclosure. In the example of Figure 3B, the CG configuration has one CG opportunity per CG period, and UCI1 transmitted in CG1 indicates resource utilization in the next upcoming period. In particular, UCI1 indicates whether the CG opportunity for CG2 is used or not.

[0056] In some embodiments, if the CG configuration has a single CG opportunity per CG period, a 1-bit notification may indicate that the next applicable CG opportunity is canceled, and the cancellation of the CG opportunity continues until the next frame arrives. For example, if UCI1 indicates that the CG opportunity for CG2 is canceled, it also implicitly indicates that the CG opportunities for CG3 through CG6 are canceled until the next frame arrives.

[0057] In some embodiments, at least one applicable CG opportunity (e.g., in at least one next slot) may be set by the second device 120. Alternatively, or additionally, the at least one applicable CG opportunity may be implicitly determined based on the processing time of the first device 110 or a processing time reference provided by the second device 120.

[0058] In summary, if the given period is a CG cycle and multiple CG opportunities are configured per CG cycle, then a 1-bit notification in the UCI: a first value of a bit indicating that a CG occurrence in a CG period immediately following the target resource is unused; a first value of the bit indicating that all CG opportunities within the CG period following the target resource are unused; a second value of the bit indicating that a CG occurrence within the CG period immediately following the target resource is to be used for CG data transmission; or a second value of the bit indicating that all CG opportunities within the CG period following the target resource are used for CG data transmission; At least one of the following can be shown.

[0059] Furthermore, if the predetermined period is a CG period and a single CG opportunity is configured per CG period, when the target resource precedes the CG transmission period in the time domain, the 1-bit notification of UCI a first value of the bit indicating that the CG opportunity in the CG period immediately following the target resource is unused; a second value of the bit indicating that a CG opportunity within the CG period immediately following the target resource will be used for CG data transmission; or a second value of the bit indicating that all CG opportunities for CG data transmission are unused until a CG data transmission occurs; At least one of the following can be shown.

[0060] In another embodiment, multiple bits (e.g., N bits) in the UCI can be set as notifications, where each of the N bits indicates whether the next N applicable CG opportunities are to be canceled. In some embodiments, each UCI carries notifications for the next N slots or CG opportunities in a sliding scale.

[0061] In some embodiments, when the CG setting of multiple CG opportunities per period is enabled, UCI is transmitted every N CG opportunities in a fixed pattern.

[0062] In some embodiments, the N unused or used CG opportunities can be considered a sliding window. That is, the first device 110 transmits such an N-bit notification for each CG opportunity for the next N slots. Returning to FIG. 3A, in this case, N=3. That is, each UCI includes three bits indicating resource utilization. Specifically, UCI1 indicates the used / unused slots of CG1_2, CG1_3, and CG2_1. Furthermore, a UCI can indicate a group of slots starting from the next slot or a group of slots starting from the same slot. In other words, the sliding window can start from the next slot or the same slot. In the former case, UCI1 indicates the used / unused slots of CG1_2, CG1_3, and CG2_1, and UCI2 indicates the used / unused slots of CG1_3, CG2_1, and CG2_2. In the latter case, UCI1 indicates the used / unused slots of CG1_1, CG1_2, and CG1_3, and UCI2 indicates the used / unused slots of CG1_2, CG1_3, and CG2_1.

[0063] In summary, if the predetermined period is a CG period and the notification includes a first number of bits in the UCI, the first number of bits indicate the use or cancellation, respectively, of a first number of CG opportunities in the CG period following the target resource, with a first value of one bit indicating that each of the first number of CG opportunities is to be unused and a second value of the bit indicating that each of the CG opportunities is to be used for CG data transmission.

[0064] In some embodiments, instead of UCI, a demodulation reference signal (DMRS) can be used to convey the notification. For example, different types of DMRS sequences can be configured in the first device 110. For example, if the next CG opportunity is used for UL data transmission, the first device 110 uses DMRS sequence #1. Otherwise, if the next CG opportunity is canceled or left unused, the first device 110 uses DMRS sequence #2. In this way, notification of resource utilization can be achieved without additional signaling overhead. As another example, different DMRS mapping patterns to resource elements (REs) can be used to indicate whether the next slot or CG opportunity is used or canceled.

[0065] In the above embodiment, the second device 120 can recognize whether the next slot or CG opportunity is used by the first device 110 based on the detected DMRS sequence or DMRS mapping pattern. Note that the DMRS detection performance only requires one bit of information.

[0066] In some embodiments, the first device 110 may be motivated to provide such notification to the second device 120. For example, the second device 120 may determine whether to increase the scheduling priority of the first device 110 based on whether the first device 110 provides such notification. Additionally or alternatively, the second device 120 may increase the scheduling priority of the first device 110 depending on (e.g., as a function of) the number of unused / canceled CG opportunities that it has been notified about.

[0067] Additionally or alternatively, in some embodiments, the scheduling priority of the first device 110 may be dynamically updated using a sliding window or moving average of the number of notified unused / canceled CG opportunities.

[0068] According to one embodiment of the present disclosure, a solution for CG transmission is provided, in which a UE determines whether at least one time slot or CG opportunity can be canceled. This allows the UE to provide a gNB with a resource utilization notification with low signaling overhead. Based on this notification, the gNB can allocate the released resources for other purposes, thereby improving resource utilization within the network.

[0069] Some steps in process 200 may be optional or skippable, and the order of steps is presented for illustrative purposes, and thus, embodiments of the present disclosure are not limited in this respect.

[0070] An exemplary description of embodiments herein, as well as potential standardization impacts and information models in standards, is provided below, with the understanding that the details, values, and configurations in the following description are provided as exemplary embodiments and are not intended to be limitations on embodiments herein.

For example, the first device may include a terminal device (e.g., a UE) or a portion of a terminal device. For ease of explanation, the method 400 is described from the perspective of the first device 110 of FIG. 1.

[0072] In block 410, the first device 110 determines whether at least one resource within a predetermined period is used for CG data transmission, the at least one resource following the target resource in the time domain.
