Configuration authorization enhancements

Abstract

Example embodiments of the present disclosure relate to configuration authorization (CG) enhancements. The apparatus determines whether at least one resource in a predetermined duration is to be used for CG data transmission, the at least one resource after the target resource in the time domain. The apparatus transmits, to the network device, an indication indicating whether the at least one resource is used or cancelled on the target resource based on a result of the determination. In this manner, the UE can indicate the use of CG opportunities in each cycle without little increase in signaling overhead. In some cases, the network may dynamically update the scheduling priority of the UE based on such an indication.

For some XR applications, due to the large and variable video frame size, multiple time slots in multiple UL CG opportunities are required to transmit XR-related data. However, due to the variable data size, not all CG opportunities can be used in one period. Therefore, there is a need to improve the resource utilization for CG transmission.

The embodiments of the present disclosure can be applied to various communication systems. In view of the rapid development of communications, there will certainly be future types of communication technologies and systems that can embody the present disclosure. The scope of the present disclosure should not be considered to be limited to the aforementioned systems.

[0032] As used herein, the term "network device" refers to a node in a communication network via which a terminal device accesses the network and receives services from it.

[0033] The term "terminal device" refers to any terminal device capable of wireless communication. By way of example and not limitation, a terminal device may also be referred to as a communication device, user equipment (UE), subscriber station (SS), portable subscriber station, mobile station (MS), or access terminal (AT).

In the following description, the terms "terminal device", "communication device", "terminal", "user equipment" and "UE" may be used interchangeably.

[0034] As used herein, the term "control device" refers to any entity / function / device / apparatus for controlling. In some example embodiments, the control device is a device for implementing domain orchestration, network optimization, and network management functions, among others.

[0035] While in various example embodiments, the functionality described herein may be performed in fixed and / or wireless network nodes, in other example embodiments, the functionality may be implemented in a user equipment device (such as a cell phone or tablet or laptop or desktop computer or mobile IoT device or fixed IoT device).

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

[0036] The main XR-related video service features in UL can be summarized as follows: Non-integer period (e.g., 16.67ms for 60fps); Packet delay budget (PDB) requirement with a baseline of 30ms and optional 10ms or 15ms; For 60fps and 10Mbit / s, the video frame size varies with an average of 20.8kbytes following a truncated Gaussian distribution.

[0037] In addition to video traffic in UL, attitude / control information can be sent using the following key features: 4ms cycle; Strict PDB requirements (10ms); 100-byte frame size.

[0038] As mentioned above, CG can be used to schedule UL data transmission, including but not limited to XR-related services. For CG-based scheduling, parameters can be configured via RRC messages. The actual UL grant can be configured via RRC for CG type 1, or provided via the Physical Downlink Control Channel (PDCCH) (addressed to CS-RNTI) for CG type 2. The main features of NR Rel-16 UL CG are as follows: ·Configure the UE with UL radio resources for transmitting one transport block at a regular time period; A period consists of 2, 7, or n*14 symbols, where the range of n depends on the configured SCS. Up to 12 CG configurations per bandwidth part (BWP), which can be configured through RRC signaling.

[0039] In many cases, due to the large and variable video size, XR-related traffic may be sent in more than one time slot. For some XR applications, such as AR, there may be different traffic in the UL, such as (i) attitude / control information every 4ms, and / or (ii) video traffic every 16.67ms for 60fps. The PDB for attitude / control information is equal to 10ms, and for UL video it is 30ms, with optional 10ms or 15ms.

[0040] To enhance XR, different types of CG configurations (e.g., one CG opportunity per cycle or multiple CG opportunities per cycle) are enabled for sending XR transmissions of various sizes. In addition, the network (such as the gNB) may want to know the CG opportunity utilization on the UE side. In this case, the gNB can allocate unused resources to another UE.

[0041] According to an exemplary embodiment of the present disclosure, a solution for CG transmission is provided. In this solution, a UE can provide an indication of used or unused opportunities for CG data transmission without excessive signaling overhead. This indication is applicable to various CG configurations, such as one CG opportunity per cycle or multiple CG opportunities per cycle.

[0042] Based on this indication, the gNB can reuse the released resources for other transmissions. Furthermore, the UE's scheduling priority can be dynamically updated based on whether the UE provides an indication and / or the number of unused resources indicated by the UE. In this way, the UE is incentivized to provide such an indication to the gNB.

[0043] Figure 1 An example communication environment 100 is shown in which example embodiments of the present disclosure may be implemented. The communication environment 100 may be a communication network that supports various types of CG configurations, such as a single CG physical uplink shared channel (PUSCH) opportunity per CG transmission cycle, or multiple CG PUSCH opportunities per CG transmission cycle. The communication network 100 includes a first device 110 and a second device 120.

[0044] The first device 110 may be a terminal device, such as a UE. The second device 120 may be a network device serving the first device 110, such as a gNB. Accordingly, the first device 110 and the second device 120 may communicate with each other. Hereinafter, the first device 110 may also be referred to as the terminal device 110 or the UE 110. The second device 120 may also be referred to as the network device 120 or the gNB 120.

[0045] In some example embodiments, the link from second device 120 to first device 110 is referred to as a downlink (DL), and the link from first device 110 to second device 120 is referred to as an uplink (UL). In the DL, second device 120 is a transmitting (TX) device (or transmitter), and first device 110 is a receiving (RX) device (or receiver). In the UL, first device 110 is a TX device (or transmitter), and second device 120 is an RX device (or receiver).

[0046] In some example embodiments, the UL transmission from the first device 110 may be scheduled by a CG. Therefore, in the context of the example embodiments, such UL transmission may also be referred to as a CG data transmission. The second device 120 may configure the first device 110 with a CG configuration. As previously described, the communication network 100 supports configurations of one CG opportunity per CG transmission cycle and multiple CG opportunities per CG transmission cycle.

[0047] The first device 110 can identify whether a time slot or opportunity configured for UL transmission is to be canceled. In some cases, not all time slots or CG opportunities can be used for CG data transmission due to, for example, variable-sized CG data transmission. In this case, the first device 110 can send a resource utilization indication to the second device 120, which indicates which CG opportunity(s) are used or not used. This indication can be sent dynamically or in a fixed manner, which will be discussed in detail below.

[0048] It should be understood that Figure 1 The number of devices and their connections shown in FIG is for illustrative purposes only and does not imply any limitation. Communication network 100 may include any suitable number of devices configured to implement the example embodiments of the present disclosure. Although not shown, it should be understood that one or more additional devices and connections may be deployed in communication network 100.

[0049] Communications in the communication environment 100 may be implemented according to any suitable communication protocol, including but not limited to first generation (1G), second generation (2G), third generation (3G), fourth generation (4G), fifth generation (5G), sixth generation (6G), etc. cellular communication protocols, wireless local area network communication protocols such as Institute of Electrical and Electronics Engineers (IEEE) 802.11, etc., and / or any other protocol currently known or developed in the future. In addition, 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 multiple access (OFDM), discrete Fourier transform spread OFDM (DFT-s-OFDM), and / or any other technology currently known or developed in the future.

[0050] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0051] Now refer to Figure 2 , which shows a signaling diagram for CG transmission according to some example embodiments of the present disclosure. Figure 2 As shown, process 200 involves a first device 110 and a second device 120. For discussion purposes, reference is made to Figure 1 Let's describe the signaling flow 200.

[0052] In process 200, data transmission from first device 110 may be scheduled based on a CG. To this end, second device 120 may configure 205 first device 110 with a CG configuration. In some example embodiments, the CG configuration may be a single CG PUSCH opportunity per CG transmission cycle. In some other example embodiments, the CG configuration may be multiple CG PUSCH opportunities per CG transmission cycle.

[0053] The first device 110 determines 210 whether at least one CG opportunity of the predetermined duration is to be used for CG data transmission. In the context of the present disclosure, the term "CG opportunity" or "CG PUSCH opportunity" refers to a time resource configured for CG data transmission, which may be of various sizes or types and includes equivalents with different names according to any suitable generation of communication protocols and / or communication standards currently known or developed in the future.

[0054] In some example embodiments, the first device 110 may determine whether an upcoming CG opportunity is required. As an example, the first device 110 may evaluate a UL buffer status and determine whether at least one upcoming CG opportunity is required based on the UL buffer status.

[0055] In some example embodiments, the first device 110 may determine whether the upcoming CG opportunity will be used or not based on whether the amount of data in the UL buffer has dropped below a data amount threshold for the UL buffer. For example, if the amount of data in the UL buffer is below the data amount threshold, the first device 110 may determine that the upcoming CG opportunity will not be used or will be canceled. Otherwise, if the amount of data in the UL buffer is not below the data amount threshold, the first device 110 may determine that the CG opportunity will be used for CG data transmission. It should be understood that the threshold may also be applicable to a state indicating that the UL buffer has become empty.

[0056] The threshold of the UL buffer is used to evaluate whether an upcoming CG opportunity is required for CG data transmission. Additionally or alternatively, in some example embodiments, the threshold of the UL buffer may be determined based on the size of the CG opportunity before the CG opportunity is indicated as not being used.

[0057] In some example embodiments, the first device 110 may decide whether an upcoming CG opportunity will be used or not based at least in part on the validity time of the UL buffer data. In particular, the validity time 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 time of the UL buffer data will expire before the upcoming CG opportunity, the first device 110 may determine that the upcoming CG opportunity is no longer needed and can therefore be released / canceled. Otherwise, if the validity time of the UL buffer data will not expire before the upcoming CG opportunity, the first device 110 may determine that the upcoming CG opportunity needs to be used to send the UL buffer data.

[0058] Additionally or alternatively, in some example embodiments, the first device 110 may decide whether the upcoming CG opportunity will be used by further considering the importance or priority of the protocol data unit (PDU) to be transmitted.

[0059] Therefore, the first device 110 sends 215 an indication indicating whether at least one CG opportunity is used or canceled to the second device 120 based on the determination result. The indication can be sent on the target resource, and the at least one CG opportunity is after the target resource in the time domain.

[0060] In some example embodiments, the predetermined duration may be at least one CG transmission period, or starting at the target resource, or starting at a sliding window of one of a first number of resources that immediately follow the target resource in the time domain, which will be discussed in detail later.

[0061] In some example embodiments, the indication may be carried via uplink control information (UCI). As an implementation, a bit in the UCI may be set to indicate, wherein the bit is set to a first value (e.g., "1") to indicate that the next applicable CG opportunity is to be canceled or not used, and the bit is set to a second value (e.g., "0") to indicate that the next applicable CG opportunity is to be used.

[0062] In addition, in an example embodiment in which multiple CG opportunities are configured in each CG transmission cycle, a 1-bit indication in the UCI indicating that the next applicable CG opportunity (e.g., in the next time slot or CG opportunity within a time slot) is not used or canceled also implicitly indicates that all subsequent opportunities in the same cycle are not used or canceled.

[0063] Figure 3A FIG2 is a schematic diagram showing an example UCI indication 300 according to some example embodiments of the present disclosure. Figure 3AIn the example shown in FIG, the CG configuration has three CG opportunities per CG period, namely, CG1_1, CG1_2, and CG1_3. UCI 1 sent in CG 1_1 indicates resource utilization in the next upcoming opportunity. Specifically, UCI 1 indicates whether the CG opportunity for CG 1_2 will be used. If UCI 1 indicates that the next opportunity is to be canceled, all remaining CG opportunities in the CG period can be implicitly canceled, such as CG 1_3.

[0064] In some example embodiments, if the CG configuration has a single CG opportunity per CG period, the 1-bit indication may indicate that the next applicable CG opportunity is canceled. Figure 3B FIG. 3 is a schematic diagram illustrating another example UCI indication 310 according to some example embodiments of the present disclosure. Figure 3B In the example of , the CG configuration has one CG opportunity per CG cycle, and UC1 sent in CG1 indicates the resource utilization in the next upcoming cycle. Specifically, UCI 1 indicates whether the CG opportunity of CG 2 will be used.

[0065] In some example embodiments, if the CG configuration has a single CG opportunity per CG period, a 1-bit indication may indicate that the next applicable CG opportunity is canceled, and the cancellation of the CG opportunity will persist until the next frame arrives. For example, if UCI 1 indicates that the CG opportunity for CG 2 is canceled, it also implicitly indicates that the CG opportunities for CG 3 to CG 6 are canceled until the next frame arrives.

[0066] In some example embodiments, at least one applicable CG opportunity (e.g., in at least one next time slot) may be configured 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 reference information of the processing time provided by the second device 120.

[0067] In summary, if the predetermined duration is a CG cycle and each CG cycle is configured with multiple CG opportunities, the 1-bit indication in the UCI may indicate at least one of the following: The first value of the bit indicates that the CG opportunity immediately following the target resource in the CG period will not be used, The first value of the bit indicates that all CG opportunities after the target resource in the CG period will not be used, The second value of the bit indicates that the CG opportunity immediately following the target resource in the CG transmission period is to be used for CG data transmission, or The second value of the bit indicates that all CG opportunities after the target resource in the CG period are to be used for CG data transmission.

[0068] In addition, if the predetermined duration is a CG period and a single CG opportunity is configured for each CG period, the target resource appears before the CG transmission period in the time domain, and the 1-bit indication in the UCI may indicate at least one of the following: The first value of the bit indicates that the CG opportunity immediately following the target resource in the CG period will not be used, The second value of the bit indicates that the CG opportunity immediately following the target resource in the CG period will be used for CG data transmission, or the second value of the bit indicates that all CG opportunities for CG data transmission will not be used until CG data transmission is completed. occur.

[0069] As another implementation, multiple bits (e.g., N bits) in the UCI may be set to indicate whether a corresponding CG opportunity in the next N applicable CG opportunities is canceled. In some example embodiments, each UCI may carry indications for the next N time slots or CG opportunities in a sliding manner.

[0070] In some example embodiments, once the CG configuration of multiple CG occasions per cycle is activated, UCI may be sent at every N CG occasions in a fixed pattern.

[0071] In some example embodiments, the N unused or used CG opportunities may be considered as a sliding window. In other words, the first device 110 may send such an N-bit indication for each CG opportunity in the next N time slots. Figure 3A , in this case, N=3, that is, each UCI may include 3 bits for indicating resource utilization. Specifically, UCI 1 indicates the used / unused time slots for CG 1_2, CG 1_3, and CG 2_1. In addition, UCI may indicate the time slot starting from the next time slot or from the same time slot. In other words, the sliding window may start from the next time slot or from the same time slot. In the former case, UCI 1 indicates the used / unused time slots for CG 1_2, CG 1_3, and CG 2_1, and UCI 2 indicates the used / unused time slots for CG 1_3, CG 2_1, and CG 2_2. In the latter case, UCI 1 indicates the used / unused time slots for CG 1_1, CG 1_2, and CG 1_3, and UCI 2 indicates the used / unused time slots for CG 1_2, CG 1_3, and CG 2_1.

[0072] In summary, if the predetermined duration is a CG cycle and the indication includes a first number of bits in the UCI, then in this case, the first number of bits may indicate the corresponding use or cancellation of a first number of CG opportunities in the CG cycle after the target resource, where the first value of the bit indicates that the corresponding CG opportunities in the first number of CG opportunities will not be used, and the second value of the bit indicates that the corresponding CG opportunities will be used for CG data transmission.

[0073] In some example embodiments, instead of UCI, a demodulation reference signal (DMRS) may be used to convey the indication. For example, different types of DMRS sequences may be configured to the first device 110. For example, if the next CG opportunity will be used for UL data transmission, the first device 110 may use DMRS sequence #1. Otherwise, if the next CG opportunity will be canceled or remain unused, the first device 110 may use DMRS sequence #2. In this way, indication of resource utilization is enabled without additional signaling overhead. For another example, different DMRS mapping patterns to resource elements (REs) may be used to indicate whether the next time slot or CG opportunity will be used or canceled.

[0074] In the above embodiment, the second device 120 can know whether the first device 110 will use the next time slot or CG opportunity based on the detected DMRS sequence or DMRS mapping pattern. It should be noted that the detection performance of DMRS should be good enough to carry only one bit of information.

[0075] In some example embodiments, first device 110 may be motivated to provide such an indication to second device 120. For example, second device 120 may determine 220 whether to increase the scheduling priority of first device 110 based on whether first device 110 provides such an indication. Additionally or alternatively, second device 120 may increase the scheduling priority of first device 110 based on (e.g., as a function of) the number of unused / canceled CG opportunities as indicated.

[0076] Additionally or alternatively, in some example embodiments, the scheduling priority of the first device 110 may be dynamically updated by using a sliding window or moving average of the number of unused / canceled CG opportunities as indicated.

[0077] According to some exemplary embodiments of the present disclosure, a CG transmission scheme is provided. With this scheme, the UE determines whether at least one time slot or CG opportunity can be canceled. Consequently, the UE can provide resource utilization indications to the gNB with low signaling overhead. Based on this indication, the gNB can allocate the released resources for other purposes, thereby improving resource utilization in the network.
