Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and device, and a computer-readable storage medium. Background Art

[0002] Delay State Report (DSR) has been introduced in extended reality (XR) scenarios. The terminal device indicates to the network the DSR Media Access Control (MAC) Control Element (CE), which contains the minimum remaining time for each logical channel group (LCG) and the amount of delay-critical packets. The remaining time is the difference between the current packet time and the discard timer expiration time. The shortest remaining time is the shortest remaining time among all packets in the LCG. Delay-critical packets include packets with a remaining time below a threshold, and / or some control packets and retransmission packets. The threshold is configured by the network. When the shortest remaining time within a LCG falls below the threshold, the terminal device triggers DSR. After the network configures uplink authorization, the terminal device performs multiplexing and reassembly, including the Logical Channel Prioritization (LCP) process. When the current LCP groups packets, it will group packets in the order of the priority of the logical channels, that is, the logical channels with higher priorities will be grouped first.

[0003] However, the time-delayed urgent data packet may be in a low-priority logical channel. According to the existing LCP packet assembly order, the time-delayed urgent data packet cannot be successfully assembled during the actual packet assembly, resulting in the time-delayed urgent data packet failing to be successfully transmitted within the delay requirements and then being discarded, affecting the user service experience.

[0041] The communication systems to which the embodiments of the present application are applicable include, but are not limited to, Long Term Evolution (LTE) systems, fifth-generation (5G) systems, new radio (NR) systems, and future evolution systems or multiple communication convergence systems. Among them, the 5G system can be a non-standalone (NSA) 5G system or a standalone (SA) 5G system. The technical solution of the present application is also applicable to different network architectures, including but not limited to relay network architecture, dual-connection architecture, vehicle-to-everything architecture and other architectures.

[0042] This application mainly relates to the communication between terminal devices and network devices. Among them:

[0043] The network device in the embodiment of the present application may also be referred to as an access network device, for example, a base station (BS) (also referred to as a base station device), which is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, the devices that provide base station functions in the second-generation (2G) network include the base transceiver station (BTS), the devices that provide base station functions in the third-generation (3G) network include the node B (NodeB), and the devices that provide base station functions in the fourth-generation (4G) network include the evolved node B (eNB). In wireless local area networks (WLAN), the device that provides base station functions is the access point (AP), and the devices that provide base station functions in NR are the next generation node base station (gNB) and the evolved node B (ng-eNB). The gNB and the terminal device communicate using NR technology, and the ng-eNB and the terminal device communicate using evolved universal terrestrial radio access (E-UTRA) technology. Both gNB and ng-eNB can be connected to the 5G core network. The network devices in the embodiments of the present application also include devices that provide base station functions in future new communication systems, etc.

[0044] The terminal equipment in the embodiments of the present application may refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents or user devices. The terminal equipment may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolved Public Land Mobile Network (PLMN), etc., and the embodiments of the present application are not limited thereto. The terminal equipment may also be referred to as User Equipment (UE), a terminal, etc.

[0045] As described in the background technology, the time-delayed urgent data packet may be in a low-priority logical channel. According to the existing LCP packet assembly order, during the actual packet assembly, it is limited by the scheduling resources allocated by the network side (for example, the resource size limit of the allocated scheduling resources, etc.), and the time-delayed urgent data packet cannot be successfully assembled. As a result, the time-delayed urgent data packet cannot be successfully transmitted within the delay requirements and is then discarded, affecting the user service experience.

[0046] This application designs a logical channel that participates in delay-aware scheduling. By configuring the first information, the terminal device can use the first resource to prioritize the transmission of delay-critical data packets under the instruction of the first information, or enable delay-aware scheduling to prioritize the transmission of delay-critical data packets, thereby prioritizing the transmission of delay-critical data packets and improving communication services, especially the smooth development of XR services.

[0047] In the technical solution of this application, delay-aware scheduling refers to a scheduling method that takes into account the remaining time in the logical channel, including considering the delay information of the data packet in the logical channel in the processes such as uplink resource allocation, logical channel priority adjustment, multiplexing and assembly, and logical channel prioritization.

[0048] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0049] See also Figure 1 The method provided in this application specifically includes the following steps:

[0050] Step 101: A network device sends first information to a terminal device.

[0051] It is understood that, in a specific implementation, the communication method can be implemented in the form of a software program, which runs in a processor integrated within a chip or chip module. The method can also be implemented in the form of software combined with hardware, which is not limited in this application.

[0052] In a non-limiting embodiment, the first information may indicate a first resource, and the first resource may be used to transmit a delay-critical packet. Specifically, the first resource may be used to transmit a delay-critical packet, i.e., may transmit a delay-critical packet or may not transmit a delay-critical packet; the first resource may also transmit both a delay-critical packet and a non-delay-critical packet simultaneously. Alternatively, the first resource may be used only to transmit a delay-critical packet.

[0053] In another non-limiting embodiment, the first information may indicate that delay-aware scheduling is enabled. Enabling delay-aware scheduling means that when the terminal device sends a transmission block (TB), data packets in the transmission block are determined based on one or more of the following: a priority of at least one logical channel, whether at least one logical channel is allowed to participate in delay-aware scheduling, whether at least one logical channel includes a delay-critical data packet, and a status of the delay-critical data packet.

[0054] In a specific implementation, the network device sends first downlink control information to the terminal device, where the first downlink control information is a new type of downlink control information (Downlink Control Information, DCI).

[0055] That is to say, by enhancing the uplink grant (UL Grant), when the terminal device receives a new type of downlink control information, the terminal device can know that the authorized resources (that is, the first resources) can be used to transmit delay-critical data packets, or enable delay-aware LCP.

[0056] In another specific embodiment, the network device sends first downlink control information to the terminal device, the first downlink control information including an indication bit, the indication bit carrying the first information. In other words, the network device explicitly indicates the first resource to the terminal device or whether to enable delay-aware scheduling through the indication bit.

[0057] In a non-limiting embodiment, the network device may configure a logical channel for the terminal device to allow it to participate in delay-aware scheduling.

[0058] Please refer to Figure 2 In step 201, the network device sends first configuration information to the terminal device. The first configuration information includes a logical channel set, and the logical channel set includes at least one logical channel allowed to participate in delay-aware scheduling.

[0059] In this embodiment, the terminal device can know which logical channels are allowed to participate in delay-aware scheduling through the first configuration information. Therefore, the terminal device can select data packets from the data packets of the above-mentioned logical channels allowed to participate in delay-aware scheduling to form a transmission block.

[0060] Furthermore, the terminal device may also select data packets from logical channels that are allowed to participate in delay-aware scheduling and have delay-critical data packets to form a transmission block.

[0061] In another specific embodiment, the terminal device may not be restricted by the above logical channel set and may directly select data packets from the logical channel with delayed urgent data packets to form a transmission block.

[0062] For example, the terminal device selects a logical channel that is allowed to participate in delay-aware scheduling; or, the terminal device selects a logical channel in which there are delayed urgent data packets (statistically counted by the terminal device); or, the terminal device selects a logical channel that is allowed to participate in delay-aware scheduling and there are delayed urgent data packets.

[0063] In a non-limiting embodiment, before step 201, the network device may send first information to the terminal device. When the first information indicates that delay-aware scheduling is enabled, the terminal device selects data packets from data packets of logical channels allowed to participate in delay-aware scheduling and / or logical channels with delay-critical data packets to form a transmission block.

[0064] When the first information indicates the first resource, the terminal device selects data packets from among the data packets of the logical channels permitted to participate in delay-aware scheduling and / or the logical channels with delay-critical data packets to form a transport block. In other words, the data packets in the transport block are selected from the logical channels permitted to participate in delay-aware scheduling and / or the logical channels with delay-critical data packets.

[0065] In step 202, the terminal device sends a transport block to the network device.

[0066] It should be noted that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0067] In an optional embodiment, the terminal device may selectively perform step 202. That is, the terminal device sends a transport block, and the data packets in the transport block are determined based on one or more of the following: the priority of at least one logical channel, whether the at least one logical channel includes a time-delayed urgent data packet, and the status of the time-delayed urgent data packet.

[0068] For example, the terminal device selects data packets from a logical channel including time-delayed urgent data packets to form a transmission block.

[0069] For another example, in a logical channel including a time-delayed urgent data packet, the terminal device selects data packets to form a transmission block according to the status of the time-delayed urgent data packet.

[0070] For another example, the terminal device selects a logical channel including a delayed urgent data packet according to the priority of the logical channel, and then selects a data packet to form a transmission block according to the status of the delayed urgent data packet.

[0071] In one variation, reference is made to Figure 2 The terminal device may also selectively receive the first information and execute step 202. In the case where the first information indicates the first resource, the terminal device sends the transport block using the first resource.

[0072] When the first information indicates that delay-aware scheduling is enabled, the data packets in the transmission block are determined based on one or more of the following: the priority of at least one logical channel, whether at least one logical channel is allowed to participate in delay-aware scheduling, whether at least one logical channel includes delay-critical data packets, and the status of the delay-critical data packets.

[0073] For example, the terminal device selects data packets to form a transmission block in a logical channel that is allowed to participate in delay-aware scheduling.

[0074] For example, the terminal device selects data packets to form a transmission block in a logical channel that is allowed to participate in delay-aware scheduling and includes delay-critical data packets.

[0075] For another example, in a logical channel that is allowed to participate in delay-aware scheduling and includes delay-critical data packets, the terminal device selects data packets to form a transmission block according to the status of the delay-critical data packets. Furthermore, the network device may pre-configure a priority range for the logical channels that participate in delay-aware scheduling. For logical channels whose priorities fall outside the priority range, the priority of the logical channel cannot be adjusted, but the logical channel may participate in the packetization process of the transmission block, that is, the data in the transmission block may also come from logical channels that are not allowed to participate in delay-aware scheduling. The data in the transmission block may also include non-delay-critical data packets.

[0076] In other words, the first resource is used first to transmit delayed urgent data packets. If there is any first resource left, non-delayed urgent data packets can be transmitted, thereby ensuring that delayed urgent data packets are transmitted first and meeting the delay requirements of delayed urgent data packets.

[0077] In a non-limiting example, see Figure 3 In step 301, the network device sends second information to the terminal device. The second information indicates that a first Hybrid Automatic Repeat reQuest (HARQ) process is prohibited from providing retransmission feedback. The first HARQ process carries a transport block containing one or more of the following: a delay-critical data packet, a data packet selected after enabling delay-aware scheduling, and a data packet in a logical channel participating in delay-aware scheduling.

[0078] In this embodiment, for delay-critical data packets, HARQ retransmission feedback is not required to reduce latency. The network device may configure, through the second information, the HARQ process and / or the HARQ process carrying the following transport blocks, namely, transport blocks including delay-critical data packets, data packets selected after enabling delay-aware scheduling, and / or data packets in a logical channel associated with delay-aware scheduling, to disable retransmission feedback or not start the HARQ timer (including the retransmission timer). Exemplarily, this configuration may be uplinkHARQ-FeedbackDisabled.

[0079] In a non-limiting example, see Figure 4 In step 401, the terminal device sends a transmission block to the network device. The same transmission block includes delayed urgent data packets or non-delayed urgent data packets. In other words, delayed urgent data packets and non-delayed urgent data packets are not grouped into the same transmission block.

[0080] Furthermore, the data packets in the transport block are selected from a logical channel having delayed urgent data packets.

[0081] In this embodiment, the terminal device determines the data packet in the transmission block according to one or more of the following: whether the logical channel includes the time-delayed urgent data packet and the status of the time-delayed urgent data packet.

[0082] For example, the terminal device selects data packets in a logical channel with delayed urgent data packets to form a transmission block.

[0083] For another example, the terminal device selects data packets in a logical channel having delayed urgent data packets to form a transmission block according to the status of the delayed urgent data packets.

[0084] In an optional embodiment, the terminal device may receive first information before sending a transport block. If the first information indicates the first resource, it means that the currently scheduled resource is a resource for transmitting a delayed emergency data packet. In this case, when selecting a logical channel, the terminal device excludes the logical channel without the delayed emergency data packet.

[0085] More specifically, during packetization, the same logical channel may contain both time-critical and non-time-critical data packets. In this case, only the time-critical data packets are grouped into a transmission block. In other words, for different logical channels, their time-critical data packets are grouped into a transmission block.

[0086] If the first information indicates that delay-aware scheduling is enabled, this means that a logical channel that is allowed to participate in delay-aware scheduling exists. The terminal device then determines the data packets in the transport block based on one or more of the following: whether the logical channel is allowed to participate in delay-aware scheduling, whether the logical channel includes a delay-critical data packet, and the status of the delay-critical data packet.

[0087] Furthermore, if the network device does not configure the first information for the terminal device, the terminal device may form a transmission block based on whether the logical channel with the highest priority during actual packet formation has a delayed urgent data packet.

[0088] In a specific implementation, if there is a delayed urgent data packet in the highest priority logical channel, the data packets in the transmission block only include the delayed urgent data packet; if there is no delayed urgent data packet in the highest priority logical channel, the data packets in the transmission block only include the non-delayed urgent data packet.

[0089] Furthermore, the logical channel with the highest priority includes one or more of the following: a logical channel with the highest priority among all logical channels; a logical channel with the highest priority among logical channels containing data.

[0090] Specifically, when the priorities of the logical channels are the same, whether the logical channel contains a delayed urgent data packet, the remaining time of the delayed urgent data packet, the data volume of the delayed urgent data packet, etc. are considered during packet assembly.

[0091] Furthermore, when the remaining time and data volume of the delayed urgent data packets are also the same, they can be sorted according to the identifiers of the logical channels when grouping the packets.
