Description

Communication method and device, and computer-readable storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 22, 2024, with application number 202410200233.X and invention name “Communication method and device, computer-readable storage medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] 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

[0003] 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.

[0004] 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.

[0052] This application mainly relates to the communication between terminal devices and network devices. Among them:

[0053] 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, in the second generation (2nd-Generation, 2G) network, the device providing the base station function includes a base transceiver station (Base Transceiver Station, BTS), in the third generation (3rd-Generation, 3G) network, the device providing the base station function includes a node B (NodeB), in the fourth generation (4th-Generation, 4G) network, the device providing the base station function includes an evolved node B (evolved NodeB, eNB), in the wireless local area network (Wireless Local Area Networks, WLAN), the device providing the base station function is an access point (Access Point, AP), and the device providing the base station function in NR is the next generation Node Base station (gNB), and the further evolved node B (ng-eNB), wherein 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, and both gNB and ng-eNB can be connected to the 5G core network. The network device in the embodiment of the present application also includes a device that provides a base station function in a future new communication system, etc.

[0054] 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.

[0055] 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 restricted by the scheduling resources allocated by the network side (for example, the size limit of the allocated scheduling resources, etc.), and the time-delayed urgent data packet cannot be successfully assembled, resulting in the time-delayed urgent data packet being unable to be successfully transmitted within the delay requirements and then being discarded, affecting the user service experience.

[0056] The technical solution of the present application sets when the terminal device adjusts the priority of the logical channel and how the priority of the logical channel is adjusted, so that delay-critical data packets can be transmitted first, or meet the delay requirements and are not discarded.

[0057] The technical solution of the present application utilizes the adjustment priority of the logical channel or the delay status of the delayed urgent data packet in the logical channel to select the transmission block, and gives priority to transmitting the delayed urgent data packet, which can ensure the transmission of the delayed urgent data packet and improve the communication business, especially the smooth development of the XR business.

[0058] 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.

[0059] Referring to FIG1 , the method provided in this application specifically includes the following steps:

[0060] Step 101: The terminal device sends a transmission block to the network device.

[0061] It should be noted that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0062] 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.

[0063] In one specific embodiment, data packets within a transport block are selected based on the adjustment priority of at least one logical channel (LCH). Specifically, the adjustment priority of a logical channel can be configured for a terminal device by a network device or determined by the terminal device based on a preset rule. The adjustment priority of a logical channel represents the priority of data packets within the logical channel during packet assembly, for example, specifically the priority of the logical channel.

[0064] Specifically, at least one logical channel has an initial priority and / or an adjusted priority. Compared with the initial priority, the adjusted priority also takes into account the status of delayed emergency data packets in the logical channel, such as whether there are delayed emergency data packets, the number of delayed emergency data packets, the shortest remaining time of delayed emergency data packets, etc., thereby ensuring that the terminal device can give priority to delayed emergency data packets when selecting data packets in the transmission block according to the adjusted priority, thereby ensuring the priority transmission of delayed emergency data packets.

[0065] It should be noted that the initial priority of each logical channel may be pre-configured by the network device for the terminal device.

[0066] In another specific embodiment, the data packets in the transmission block are selected based on the delay status of the delayed urgent data packets in at least one logical channel.

[0067] Furthermore, the delay status includes one or more of the following: the number of delayed urgent data packets, the shortest remaining time among the remaining times of all delayed urgent data packets in the logical channel, and the distribution of the remaining time of each delayed urgent data packet in the logical channel.

[0068] Furthermore, the priority of a logical channel with a larger number of delayed emergency data packets is higher than the priority of a logical channel with a smaller number of delayed emergency data packets, or the priority of a logical channel with a shorter minimum remaining time is higher than the priority of a logical channel with a longer minimum remaining time, or the priority of a logical channel with a minimum remaining time lower than a first threshold and a number of delayed emergency data packets higher than a second threshold is higher than the priority of a logical channel with a minimum remaining time of other values ​​and a different number of delayed emergency data packets. The priority here may be an adjusted priority.

[0069] For example, the logical channel whose shortest remaining time is lower than the first threshold and the number of delayed emergency data packets is higher than the second threshold has the highest adjustment priority;

[0070] The logical channel whose shortest remaining time is lower than the first threshold and the number of delayed emergency data packets is lower than the second threshold has the next highest adjustment priority;

[0071] The logical channel whose shortest remaining time is higher than the first threshold and whose number of delayed emergency data packets is higher than the second threshold has the next highest adjustment priority;

[0072] The adjustment priority of the logical channel whose shortest remaining time is higher than the first threshold and the number of delayed emergency data packets is lower than the second threshold is the next highest.

[0073] Furthermore, when the adjustment priorities of the logical channels are the same, the terminal device can determine the data packets in the transmission block according to the initial priorities of the logical channels.

[0074] Furthermore, when the delay states of the delayed urgent data packets in the logical channels are the same, the terminal device can determine the data packets in the transmission block according to the initial priority of the logical channel.

[0075] Furthermore, when the adjustment priority of the logical channels is the same or the delay status of the delayed emergency data packets in the logical channels is the same, the terminal device can determine the data packets in the transmission block according to the order of the logical channel identifiers (for example, ascending or descending).

[0076] In yet another specific embodiment, the data packets in the transport block are selected based on an adjustment priority of at least one logical channel and a delay status of a delayed urgent data packet in the logical channel.

[0077] Specifically, when the adjustment priorities of the logical channels are the same, a data packet in the transport block is selected based on the delay status of the delayed urgent data packets in the logical channels. Alternatively, when the delay status of the delayed urgent data packets in the logical channels is the same, for example, the number of delayed urgent data packets and / or the shortest remaining time in the logical channels are the same, a data packet in the transport block is selected based on the adjustment priority of the logical channels.

[0078] It should be noted that the same as mentioned in the embodiments of the present application may mean that the numerical values ​​are completely equal, the numerical difference is within a certain range, or the quantized indexes are equal. The present application does not impose any restrictions on this.

[0079] In a non-limiting embodiment, the adjustment priority may be configured by the network device for the terminal device.

[0080] In this embodiment, after the terminal device sends the DSR, the terminal device receives the priority of the logical channel configured by the network device, and this priority is the adjustment priority.

[0081] 2 , in step 201, the network device sends first configuration information to the terminal device. The first configuration information indicates an adjustment priority of at least one logical channel.

[0082] In a specific embodiment, the network device sends downlink control information (DCI), medium access control (MAC) control element (CE) or radio resource control (RRC) to the terminal device, and the above signaling carries the first configuration information.

[0083] In step 202, the terminal device sends a transport block to the network device. The terminal device selects data packets in the transport block according to the adjustment priority of at least one logical channel and / or the delay status of the delayed urgent data packets in at least one logical channel.

[0084] Furthermore, the first configuration information includes an adjustment priority set and an identifier of the adjustment priority.

[0085] Then, in a specific implementation of step 201, the terminal device receives an adjustment priority set, which includes each adjustment priority and its identifier; the terminal device then receives the identifier of the adjustment priority, which may specifically be a priority index.

[0086] Specifically, the adjustment priority set can be configured for each logical channel, and the adjustment priority identifier corresponds to the logical channel; or it can be configured for each logical channel group (Logical Channel Group, LCG), then the adjustment priority identifier corresponds to the logical channel group; or the adjustment priority set can be configured for all LCH / LCG, then the adjustment priority identifier corresponds to all LCH / LCG.

[0087] Furthermore, the first configuration information may also indicate other parameters besides the logical channel priority, such as

[0088] - Prioritized Bit Rate, used to set the priority bit rate (prioritisedBitRate which sets the Prioritized Bit Rate (PBR));

[0089] - Token bucket duration, used to set the token bucket duration (bucketSizeDuration which sets the Bucket Size Duration (BSD)).

[0090] Furthermore, the first configuration information may further include mapping restriction parameters for each LCP in the LCP process. The mapping restriction parameters may specifically include one or more of the following:

[0091] - allowed subcarrier spacing (SCS) list, used to set the allowed subcarrier spacing for transmission (allowedSCS-List which sets the allowed subcarrier spacing(s) for transmission);

[0092] - Maximum Physical Uplink Shared Channel (PUSCH) duration, which sets the maximum PUSCH duration allowed for transmission;

[0093] - configuredGrantType1Allowed which sets whether a configured grant Type 1 can be used for transmission;

[0094] - allowed serving cells, which sets the allowed cells for transmission (allowedServingCells which sets the allowed cell(s) for transmission);

[0095] - allowed CG list, used to set the allowed transmission configuration authorization (allowedCG-List which sets the allowed configured grant(s) for transmission);

[0096] - allowedPHY-PriorityIndex which sets the allowed PHY priority index(es) of a dynamic grant for transmission;

[0097] - allowedHARQ-mode which sets the allowed UL HARQ mode for transmission.

[0098] Furthermore, the first configuration information may also configure the Bj size of the logical channel LCH j, where Bj is not restricted and Bj, etc., is not considered.

[0099] Furthermore, for multiple logical channels with the same adjustment priority, the terminal device may determine the target priorities of the multiple logical channels, and then determine the data packets in the transport block based on the target priorities of the multiple logical channels. The terminal device may determine the target priorities of the multiple logical channels in one or more of the following ways:

[0100] Mode 1: The target priority of the logical channel with delayed urgent data packets is higher than the target priority of the logical channel without delayed urgent data packets;

[0101] Mode 2: The target priority of the logical channel with a larger number of delayed urgent data packets is higher than the target priority of the logical channel with a smaller number of delayed urgent data packets;

[0102] Mode 3: The target priority of a logical channel with a shorter minimum remaining time is higher than the target priority of a logical channel with a longer minimum remaining time;

[0103] Method 4: The target priority of a logical channel whose shortest remaining time is lower than the first threshold and the number of delayed emergency data packets is higher than the second threshold is higher than the target priority of a logical channel with the shortest remaining time of other values ​​and other numbers of delayed emergency data packets.

[0104] For example, the target priority of the logical channel whose shortest remaining time is lower than the first threshold and the number of delayed emergency data packets is higher than the second threshold is the highest;

[0105] The target priority of the logical channel whose shortest remaining time is lower than the first threshold and the number of delayed emergency data packets is lower than the second threshold is the second;

[0106] The target priority of the logical channel whose shortest remaining time is higher than the first threshold and the number of delayed urgent data packets is higher than the second threshold is the second;

[0107] The target priority of the logical channel whose shortest remaining time is higher than the first threshold and the number of delayed emergency data packets is lower than the second threshold is next.

[0108] Mode 5: The target priority of the logical channel participating in delay-aware scheduling is higher than the target priority of the logical channel not participating in delay-aware scheduling. In this case, whether the logical channel participates in delay-aware scheduling can be pre-configured by the network device for the terminal device.

[0109] It should be noted that the specific values ​​of the first threshold and the second threshold can be configured or indicated by the network device, for example, included in the first configuration information or the second configuration information, or specified by the communication standard protocol, and this application does not impose any restrictions on this.

[0110] In another non-limiting embodiment, the adjustment priority may be determined by the terminal device according to the delay status of the delayed emergency data packet in the logical channel.

[0111] In this embodiment, the terminal device receives the initial priority configured by the network device, and then adjusts the initial priority of the logical channel. The adjusted priority is the adjusted priority.

[0112] In this embodiment, for multiple logical channels having the same initial priority, the terminal device determines the adjustment priorities of the multiple logical channels in one or more of the following ways:

[0113] Mode A: The adjustment priority of the logical channel with delayed urgent data packets is higher than the adjustment priority of the logical channel without delayed urgent data packets;

[0114] Mode B: the adjustment priority of the logical channel with a larger number of delayed urgent data packets is higher than the adjustment priority of the logical channel with a smaller number of delayed urgent data packets;

[0115] Mode C: The adjustment priority of the logical channel with a shorter minimum remaining time is higher than the adjustment priority of the logical channel with a longer minimum remaining time;

[0116] Method D, the adjustment priority of the logical channel whose shortest remaining time is lower than the first threshold and the number of delayed emergency data packets is higher than the second threshold is higher than the adjustment priority of the logical channel with the shortest remaining time of other values ​​and other numbers of delayed emergency data packets.

[0117] Mode E: The adjustment priority of the logical channel participating in delay-aware scheduling is higher than the adjustment priority of the logical channel not participating in delay-aware scheduling. In particular, whether the logical channel participates in delay-aware scheduling can be pre-configured by the network device for the terminal device.

[0118] In another non-limiting embodiment, the network device configures a priority adjustment rule of a logical channel to the terminal device, and the terminal device determines the adjustment priority of the logical channel.

[0119] 3 , in step 301 , the network device sends second configuration information to the terminal device. The second configuration information includes one or more of the following: a logical channel priority adjustment rule, a set of logical channels whose initial priorities are allowed to be adjusted, and a priority range allowed to be adjusted.

[0120] Then, the terminal device determines the adjustment priority of the logical channel according to the configuration of the second configuration information and the logical channel priority adjustment rule within the set of logical channels that allow adjustment of the initial priority and / or within the priority range that allows adjustment.

[0121] This embodiment can avoid affecting the logical channel data transmission of certain signaling radio bearers (SRBs) 1, such as the RRC reconfiguration completion message, thereby affecting network performance by setting a logical channel set that allows adjustment of the initial priority and / or a priority range that allows adjustment.

[0122] In a specific embodiment, the logical channel priority adjustment rules include one or more of the following: data packets in the transmission block give priority to delayed urgent data packets in the logical channel; when there are no delayed urgent data packets in the logical channel, the data packets in the transmission block are selected according to the priority of the logical channel, for example, the priority of the logical channel here is the initial priority of the logical channel.

[0123] In another specific embodiment, the logical channel priority adjustment rule includes one or more of the following:

[0124] Rule 1: The adjustment priority of a logical channel containing time-delayed emergency data packets is higher than the adjustment priority of a logical channel without time-delayed emergency data packets. For the terminal device, time-delayed emergency data packets are prioritized for packet assembly. After the time-delayed emergency data packets are assembled, the transmission block is formed according to the initial priority of the logical channel (i.e., the priority of the logical channel in the prior art).

[0125] Furthermore, the second configuration information also includes a priority range for allowed packet grouping. For the first logical channel whose priority is within the priority range for allowed packet grouping, the data packets in the transmission block give priority to the delayed urgent data packets in the first logical channel; when there are no delayed urgent data packets in the first logical channel, the data packets in the transmission block are selected according to the priority of each logical channel.

[0126] That is to say, the terminal device can give priority to the delayed urgent data packets for packetization within the priority range allowed for packetization, and after the delayed urgent data packets are completed, packetization is performed according to the initial priority of the logical channel.

[0127] Rule 2: The adjustment priority of a logical channel with a larger number of delayed urgent data packets is higher than the adjustment priority of a logical channel with a smaller number of delayed urgent data packets.

[0128] Rule 3: The adjustment priority of a logical channel with a shorter minimum remaining time is higher than the adjustment priority of a logical channel with a longer minimum remaining time.

[0129] Rule 4: The adjustment priority of a logical channel whose shortest remaining time is lower than the first threshold and the number of delayed emergency data packets is higher than the adjustment priority of a logical channel with the shortest remaining time of other values ​​and other numbers of delayed emergency data packets.

[0130] For example, the logical channel whose shortest remaining time is lower than the first threshold and the number of delayed emergency data packets is higher than the second threshold has the highest priority;

[0131] The priority of the logical channel whose shortest remaining time is lower than the first threshold and the number of delayed emergency data packets is lower than the second threshold is the next highest;

[0132] The priority of the logical channel whose shortest remaining time is higher than the first threshold and the number of delayed emergency data packets is higher than the second threshold is the next highest;

[0133] The priority of the logical channel whose shortest remaining time is higher than the first threshold and the number of delayed emergency data packets is lower than the second threshold is next highest.

[0134] Rule 5: Calculate the adjustment priority of the logical channel based on the shortest remaining time of the logical channel and / or the number of delayed emergency data packets in the logical channel.

[0135] For example, first compare the shortest remaining time, and when the shortest remaining time is the same, calculate the adjustment priority of the logical channel according to the number of delayed emergency data packets; or first compare the number of delayed emergency data packets, and when the number of delayed emergency data packets is the same, calculate the adjustment priority of the logical channel according to the shortest remaining time.

[0136] For another example, new LCH priority is calculated according to the formula: new LCH priority = K × (T)^m + H × (N)^n; K, where T represents the shortest remaining time, N represents the number of delayed emergency data packets, and H, m, and n are weight coefficients configured by the network side.

[0137] Rule 6: Calculate the adjustment priority of the logical channel based on the shortest remaining time of the logical channel, the number of delayed emergency data packets in the logical channel and / or the initial priority of the logical channel.

[0138] For example, New LCH priority = K×(T)^m+H×(N)^n+a×(P1)^r, where P1 represents the initial priority of the logical channel, and K, H, m, n, a, and r are weight coefficients.

[0139] In a non-limiting embodiment, the terminal device groups delayed urgent data packets and non-delayed urgent data packets according to different priorities.

[0140] Specifically, please refer to Figure 4. In step 401, for delayed urgent data packets in the logical channel, they are selected to the transmission block according to the adjustment priority of the logical channel; for non-delayed urgent data packets in the logical channel, they are selected to the transmission block according to the initial priority of the logical channel.

[0141] In this embodiment, the adjustment priority of the logical channel may be configured by the network device in the aforementioned second configuration information, or may be determined by the terminal device according to a priority adjustment rule.

[0142] It is understandable that the initial priority of the logical channel can be configured according to the method in the prior art, and this application does not limit this.

[0143] In an optional embodiment, the terminal device receives third configuration information, which includes the first priority of at least one logical channel; wherein, for delayed emergency data packets in the logical channel, they are selected to the transmission block according to the first priority (i.e., the adjusted priority), and for non-delayed emergency data packets in the logical channel, they are selected to the transmission block according to the second priority (i.e., the initial priority).

[0144] In this embodiment, at least one logical channel has two priorities, namely a first priority and a second priority. The first priority is configured by the network device through third configuration information, and the second priority may be the initial priority of the logical channel.

[0145] In another optional embodiment, the terminal device receives third configuration information, which includes a first priority and a second priority of at least one logical channel; wherein, for delayed emergency data packets in the logical channel, the transmission block is selected according to the first priority, and for non-delayed emergency data packets in the logical channel, the transmission block is selected according to the second priority.

[0146] In this embodiment, at least one logical channel has two priorities, namely a first priority and a second priority. Both priorities are configured by the network device through third configuration information.

[0147] Unlike the previous embodiment, the first priority and the second priority can be configured by the network device in the same signaling. For example, the first priority and the second priority can be configured in a new type of downlink information. In addition, the second priority can be the same as the initial priority of the logical channel, or it can be different from the initial priority of the logical channel (i.e., the priority reconfigured by the network for the non-delayed emergency data packets of the logical channel).

[0148] 4 , in step 402 , the terminal device sends a transmission block to the network device.

[0149] In a non-limiting embodiment, for a logical channel including delayed emergency data packets, different adjustment priorities of the logical channel are determined based on the remaining time distribution of the delayed emergency data packets, wherein the adjustment priority of the logical channel with a shorter minimum remaining time is higher than the adjustment priority of the logical channel with a longer minimum remaining time.

[0150] In this embodiment, as the shortest remaining time of a data packet in a logical channel changes, the adjustment priority of the logical channel also changes.

[0151] For example, the shortest remaining time of the logical channel LCH1 is 5ms, and the adjustment priority of LCH1 is 1;

[0152] After the data packets with a remaining time of 5 ms are grouped, the shortest remaining time of the logical channel LCH1 is 10 ms, and the adjustment priority of LCH1 is updated to 2;

[0153] After the data packets with a remaining time of 10ms are grouped, the shortest remaining time of the logical channel LCH1 is 15ms, and the adjustment priority of LCH1 is updated to 3;

[0154] In other cases, the priority of LCH1 is the initial priority.

[0155] For example, for at least one logical channel including time-delay emergency data packets, different adjustment priorities of the at least one logical channel are determined according to the remaining time distribution of the time-delay emergency data packets, where the adjustment priority of the logical channel with a shorter shortest remaining time is higher than that of the logical channel with a longer shortest remaining time.

[0156] In a specific embodiment, for example:

[0157] For logical channels LCH 1 and LCH2, the remaining times of the time-delay emergency data packets in logical channel LCH 1 are 5 ms and 7 ms respectively, and the remaining times of the time-delay emergency data packets in logical channel LCH2 are 6 ms and 10 ms respectively.

[0158] Then, the priority order of LCH 1 and LCH2 is as follows:

[0159] The remaining time of the time-delay emergency data packet in LCH 1 is 5 ms, the data volume is 40 Bytes, and the priority of LCH1 is 1;

[0160] The remaining time of the time-delay emergency data packet in LCH two is 6 ms, the data volume is 30 Bytes, and the priority of LCH2 is 2;

[0161] The remaining time of the time-delay emergency data packet in LCH1 is 7 ms, the data volume is 50 Bytes, and the priority of LCH1 is 3;

[0162] The remaining time of the time-delay emergency data packet in LCH2 is 10 ms, the data volume is 20 Bytes, and the priority of LCH2 is 4.

[0163] In a specific example, LCH1 is configured with parameter Bj1, where the number of time-delay emergency data packets in LCH1 is a, and the number of non-time-delay emergency data packets is b, a < Bj1 < a + b; LCH2 is configured with parameter Bj2, where the number of time-delay emergency data packets is c, and the number of non-time-delay emergency data packets is d, c < Bj2 < c + d; the network device indicates that the authorized resource is m, Bj1 + Bj2 < m < a + b + c + d.

[0164] When performing time-delay-aware scheduling, the priority of LCH1 is higher than that of LCH2; when performing non-time-delay-aware scheduling, the priority of LCH1 is lower than that of LCH2; then when the terminal device assembles packets, the following steps are executed in sequence:

[0165] 1. First assemble a of LCH1, and the remaining packet-assembling quantity of LCH1 is: Bj1 - a;

[0166] 2. Then assemble c of LCH2, and the remaining packet-assembling quantity of LCH2 is: Bj2 - c;

[0167] 3. At this time, there is no delay in the urgent data packet, and the priority of LCH1 is restored to LCH1 lower than LCH2; continue to assemble the packet.

[0168] 4. Then, part d of LCH2 (i.e., Bj2-c) is packaged into a MAC packet data unit (PDU), and d-(Bj2-c) remains unpackaged.

[0169] 5. Then part b of LCH1 (i.e. Bj1-a) is grouped into the MAC PDU, and b-(Bj1-a) remains unpacked.

[0170] 6. At this point, Bj1 and Bj2 of LCH2 and LCH1 are used up, and the package assembly continues;

[0171] 7. At this point, the remaining portion of LCH2 is grouped into the transport block, and there are no remaining packets in LCH2.

[0172] 8. Some data packets of LCH1 are grouped into the transmission block, and b-(macd) remains ungrouped into the transmission block.

[0173] In a non-limiting embodiment, the network device may further configure a second logical channel for the terminal device that allows adjustment of the initial priority.

[0174] Specifically, referring to Figure 5 , in step 501, the network device sends fourth configuration information to the terminal device. The fourth configuration information configures whether at least one second logical channel allows adjustment of the initial priority. In other words, it configures whether at least one second logical channel participates in delay-aware scheduling (LDP). Specifically, the second logical channel can be a specific logical channel or a specific logical channel group.

[0175] That is, when the second channel allows adjustment of the initial priority, the terminal device adjusts its initial priority to obtain the adjusted priority of the second logical channel.

[0176] Furthermore, under the configuration of the fourth configuration information, the terminal device adjusts the initial priority according to one or more of the following methods:

[0177] Mode A1: adjusting the initial priority of the third logical channel belonging to the at least one second logical channel among the logical channels corresponding to the extended display service in the delay status report; or

[0178] Mode A2: Adjust the initial priority of the fourth logical channel belonging to the at least one second logical channel in the corresponding logical channel in the delay status report;

[0179] Mode A3: Adjust the initial priority of the corresponding logical channel in the delay status report; or

[0180] Mode A4: adjusting the initial priority of the at least one second logical channel;

[0181] Mode A5: adjusting the initial priority of the fifth logical channel that contains the emergency data packet and belongs to the at least one second logical channel;

[0182] Method A6: Adjust the initial priority of the logical channel containing the emergency data packet;

[0183] Mode A7: Receive the first signaling, and adjust the initial priority of the sixth logical channel indicated by the first signaling.

[0184] The above method is executed by the terminal device when it is deactivated by default.

[0185] In one specific embodiment, the network device may send a DCI, MAC CE, or RRC to the terminal device, where the signaling carries the fourth configuration information. That is, the network device configures whether the logical channel / logical channel group participates in delay-aware scheduling through DCI, MAC CE, or RRC signaling.

[0186] Specifically, the DCI may include an indication bit, such as a 1-bit indication bit, or an implicit indication method, such as a new type of UL Grant / DCI, indicating whether the terminal device is allowed to enable delay-aware scheduling.

[0187] In another specific embodiment, when the default is activated, the terminal device adjusts the initial priority according to one or more of the following methods:

[0188] Mode A8: prohibiting the adjustment of the priority of the logical channel corresponding to the non-extended display service in the delay status report;

[0189] Mode A9: prohibiting adjustment of the priority of the seventh logical channel belonging to the at least one second logical channel among the logical channels corresponding to the delay status report;

[0190] Mode A10: prohibiting the adjustment of the priority of the logical channel corresponding to the delay status report;

[0191] Mode A11: prohibiting adjustment of the priority of the at least one second logical channel;

[0192] Mode A12: prohibiting the adjustment of the priority of logical channels that do not contain emergency data packets;

[0193] Mode A13: Receive the second signaling, and prohibit adjusting the priority of the eighth logical channel indicated by the second signaling.

[0194] In another specific embodiment, the terminal device determines whether to adjust the initial priority of the logical channel according to actual conditions, and performs one or more of the following steps:

[0195] Mode A14 adjusts the initial priority of the ninth logical channel corresponding to the extended display service in the delay status report;

[0196] Mode A15: Adjust the initial priority of the tenth logical channel corresponding to the delay status report;

[0197] Mode A16: Adjusting the initial priority of the at least one logical channel;

[0198] Mode A17: Adjust the initial priority of the logical channel containing the emergency data packet;

[0199] Mode A18: Receive the third signaling, and adjust the initial priority of the eleventh logical channel indicated by the third signaling.
