Description

Technical Field

[0001] This application relates to a transmission method in a wireless communication system, involving enhanced Logical Channel Prioritization (LCP), especially a method for XR (Extended Reality) services. Background Art

[0002] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios pose different performance requirements on the system. To meet the different performance requirements of various application scenarios, it was decided at the 72nd plenary session of 3GPP (3rd Generation Partnership Project) RAN (Radio Access Network) to conduct research on the New Radio (NR) (or Fifth Generation, 5G) new air interface technology. At the 75th plenary session of 3GPP RAN, the WI (Work Item) of NR was approved, and the standardization work of NR began.

[0003] In communication, both LTE (Long Term Evolution) and 5G NR involve accurate reception of reliable information, optimized energy efficiency ratio, determination of information effectiveness, flexible resource allocation, scalable system architecture, efficient non-access stratum information processing, low service interruption and disconnection rates, support for low power consumption. This is of great significance for the normal communication between base stations and user equipment, for the reasonable scheduling of resources, and for the load balancing of the system. It can be said to be the cornerstone of high throughput, meeting the communication needs of various services, improving spectrum utilization, and improving service quality. It is indispensable for both eMBB (enhanced Mobile BroadBand), URLLC (Ultra Reliable Low Latency Communication), and eMTC (enhanced Machine Type Communication). Logical channel optimization is an important technology in wireless communication systems. It involves the effective allocation and use of wireless resources to ensure network performance and user experience. With the development of wireless communication technology, new technologies and methods are constantly being introduced into logical channel optimization to adapt to higher data transmission rates, better service quality requirements, and more complex network environments.

[0004] With the continuous increase in the scenarios and complexity of the system, higher requirements are put forward for reducing the interruption rate, reducing latency, enhancing reliability, enhancing the stability of the system, the flexibility of services, and power savings. At the same time, when designing the system, the compatibility between different system versions also needs to be considered. Summary of the Invention

[0005] Researchers have found that in the scenario of logical channel optimization by terminals in a wireless communication system, the problem that some delay-critical data cannot be transmitted in time needs to be solved.

[0006] In response to the above problems, the present application provides a solution. In the above problem description, the NR system is taken as an example, and the present application is also applicable to scenarios such as LTE (Long-Term Evolution), LTE-A (Long-Term Evolution Advanced), 5G+, or 6G systems, achieving similar technical effects to the NR system; further, although the present application gives specific implementation manners for transmitting delay-critical data without tokens, the present application can also be used to solve other communication problems, such as network optimization, artificial intelligence, and mobility management; the method proposed in the present application is also very suitable for solving problems in network convergence scenarios. Further, adopting a unified design solution for different scenarios also helps to reduce hardware complexity and cost. Further, although the original intention of the present application is for the Uu air interface, the present application can also be used for the PC5 interface, achieving similar technical effects to the Uu air interface. Further, although the original intention of the present application is for the terminal-to-base station scenario, the present application is also equally applicable to the V2X (Vehicle-to-Everything) scenario, the communication scenarios between terminals and relays, and between relays and base stations, achieving similar technical effects to the terminal-to-base station scenario. Further, although the original intention of the present application is for the terminal-to-base station scenario, the present application is also equally applicable to the IAB (Integrated Access and Backhaul) communication scenario, achieving similar technical effects to the terminal-to-base station scenario. Further, although the original intention of the present application is for the terrestrial network (TN) scenario, the present application is also equally applicable to the non-terrestrial network (NTN) communication scenario, achieving similar technical effects to the TN scenario. In addition, adopting a unified solution for different scenarios also helps to reduce hardware complexity and cost.

[0166] As an example, Bj is a parameter for logical channel prioritization (LCP).

[0167] As an example, when a logical channel is established, the MAC entity initializes Bj of this logical channel to 0.

[0168] As an example, for any logical channel j, during each LCP, the MAC entity increases Bj by PBR×T, where T is the time elapsed since Bj was last increased, and PBR is the priority data rate.

[0169] As an example, the PBR of any logical channel is indicated by the network.

[0170] As an example, the PBR of any logical channel is indicated by the first signaling.

[0171] As an example, when the value of Bj is greater than the size of the bucket, Bj is set to the size of the bucket, where the size of the bucket is equal to PBR×BSD, and BSD is configured by the network.

[0172] As an example, for a new transmission, the MAC entity allocates resources as follows: for logical channels with Bj greater than 0, resources are allocated for the first uplink grant in descending order of priority.

[0173] As an example, if the PBR of one of the at least first logical channels is infinite, all data of this logical channel is allocated resources before considering logical channels with lower priority.

[0174] As an example, reduce Bj of any logical channel j by the sum of all MAC SDUs (service data units) that have transmitted data of this logical channel j.

[0175] As an embodiment, the meaning that whether a logical channel is selected depends on the first variable of this logical channel includes: under the condition that parameters other than the first variable of the logical channel are the same, the data to be transmitted on the logical channel with a larger first variable is preferentially transmitted.

[0176] As an embodiment, the meaning that whether a logical channel is selected depends on the first variable of this logical channel includes: under the condition that parameters other than the first variable of the logical channel are the same, the data to be transmitted on the logical channel with a smaller first variable is preferentially transmitted.

[0178] As an embodiment, the only part is or corresponds to Bj of the target logical channel.

[0179] As an embodiment, the size of the only part is indicated by the first signaling.

[0180] As an embodiment, the only part refers to the data with a higher priority in the target logical channel.

[0181] As an embodiment, the only part refers to delay-critical data.

[0183] As an embodiment, selecting at least a first logical channel for a first uplink grant includes: the data of the logical channel with a higher priority is always transmitted prior to the data of the logical channel with a lower priority.

[0184] As an embodiment, the meaning that the data of a logical channel is preferentially transmitted includes: when selecting for the first uplink grant, this logical channel is preferentially selected.

[0185] As an embodiment, the meaning that the data of a logical channel is preferentially transmitted includes: when allocating resources for the logical channel, this logical channel is preferentially allocated resources.

[0186] As an embodiment, the at least first logical channel includes multiple logical channels.

[0187] As an embodiment, allocating resources for the data of the at least first logical channel includes: for all other logical channels among the at least first logical channels except the target logical channel, all the data to be transmitted is allocated resources.

[0188] As an example, the target logical channel is the logical channel with the lowest priority among the at least first logical channels.

[0189] As an example, maintaining a first variable for the first logical channel includes initializing it to 0, incrementing, and decrementing the first variable.

[0190] As an example, maintaining a first variable for the first logical channel includes modifying the first variable according to the progress of the LCP (Logical Channel Prioritization) process.

[0191] As an example, transmitting at least one MAC PDU depending on at least the latter of the data type and the first variable includes transmitting at least one MAC PDU depending only on the first variable; and transmitting at least one MAC PDU depending on the data type and the first variable.

[0192] As an example, the first threshold and the second threshold are pre-configured.

[0193] As an example, the first threshold and the second threshold are network-configured. The advantage of doing so is that the network can obtain more comprehensive information and make an optimal decision.

[0194] As an example, the first threshold and the second threshold are terminal-configured. The advantage of doing so is that the terminal can make adjustments according to its own services and more flexibly support XR services, etc.

[0195] As an example, the first threshold and the second threshold are real numbers.

[0196] As an example, the first threshold is not equal to the second threshold.

[0197] As an example, the first threshold is less than the second threshold.

[0198] As an example, the first threshold is negative. The advantage is that it can transmit delay-critical data in a timely manner, reduce latency, and ensure that the service is more efficient in a timely manner.

[0199] As an example, the second threshold is 0. The advantage is that it can ensure a certain transmission rate for the first logical channel with low priority and avoid the logical channel with low priority being unable to be allocated resources all the time.

[0200] As an example, the second threshold is positive. The advantage is that it can reserve a part of the uplink grant to cope with unexpected situations, such as scenarios where a large amount of data with higher priority needs to be transmitted suddenly.

[0201] As an example, the transmission of the at least one MAC PDU depends on the type of the data of the at least first logical channel and at least the latter of the first variables, including: when the first variable is not greater than the first threshold, the at least one MAC PDU is not transmitted.

[0202] As an example, when the type of the data of the at least first logical channel is delay-critical data and the first variable is greater than the first threshold, the at least one MAC PDU is transmitted; the meaning of transmitting the at least one MAC PDU when the first variable is greater than the second threshold is: the at least one MAC PDU is transmitted only when the type of the data of the at least first logical channel is delay-critical data and the first variable is greater than the first threshold or the first variable is greater than the second threshold.

[0203] As an example, when the type of the data of the at least first logical channel is delay-critical data and the first variable is greater than the first threshold, the at least one MAC PDU is transmitted; the meaning of transmitting the at least one MAC PDU when the first variable is greater than the second threshold is: when the type of the data of the at least first logical channel is delay-critical data and the first variable is not greater than the first threshold and the first variable is not greater than the second threshold, the at least one MAC PDU is not transmitted.

[0219] Example 3

[0220] Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to the present application, as shown in the appendix Figure 3 as shown. Figure 3 It is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3The radio protocol architecture of the control plane 300 for a terminal (UE, gNB) and a network node (gNB, UE), or between two UEs, is shown in three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. The L1 layer will be referred to as PHY 301 in this document. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the terminal and the network node and between two UEs through PHY 301. The L2 layer 305 includes a MAC (Medium Access Control) sub-layer 302, an RLC (Radio Link Control) sub-layer 303, and a PDCP (Packet Data Convergence Protocol) sub-layer 304, and these sub-layers terminate at the network node. The PDCP sub-layer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sub-layer 304 also provides security by encrypting data packets and provides support for handover of the terminal between network nodes. The RLC sub-layer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for disordered reception due to HARQ. The MAC sub-layer 302 provides multiplexing between logical and transport channels. The MAC sub-layer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell between terminals. The MAC sub-layer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sub-layer 306 in Layer 3 (L3 layer) of the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the network node and the terminal. The PC5-S (PC5 Signaling Protocol) sub-layer 307 is responsible for the processing of the signaling protocol of the PC5 interface. The radio protocol architecture of the user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). For the physical layer 351, the PDCP sub-layer 354 in the L2 layer 355, the RLC sub-layer 353 in the L2 layer 355, and the MAC sub-layer 352 in the L2 layer 355, the radio protocol architecture for the terminal and the network node in the user plane 350 is generally the same as the corresponding layers and sub-layers in the control plane 300, but the PDCP sub-layer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead.The L2 layer 355 in the user plane 350 further includes an SDAP (Service Data Adaptation Protocol) sub-layer 356. The SDAP sub-layer 356 is responsible for the mapping between QoS flows and data radio bearers (DRBs) to support service diversity. The SRB can be regarded as a service or interface provided by the PDCP layer to higher layers, such as the RRC layer. In the NR system, the SRB includes SRB1, SRB2, and SRB3, which are respectively used to transmit different types of control signaling. The SRB is a bearer between the UE and the access network and is used to transmit control signaling including RRC signaling between the UE and the access network. SRB1 is of particular significance to the UE. After each UE establishes an RRC connection, there will be an SRB1 for transmitting RRC signaling. Most signaling is transmitted through SRB1. If SRB1 is interrupted or unavailable, the UE must perform RRC reconstruction; one SRB1 is established for each RRC connection. SRB2 is generally only used to transmit NAS signaling or signaling related to security; one SRB2 is established for each RRC connection. The UE may not be configured with SRB3. Except for emergency services, the UE must establish an RRC connection with the network to perform subsequent communication. Although not shown, the terminal may have several upper layers above the L2 layer 355. In addition, it also includes a network layer (e.g., IP layer) terminated at the P-GW on the network side and an application layer terminated at the other end of the connection (e.g., a remote UE, a server, etc.).

[0225] Example 4

[0226] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to an embodiment of this application, as shown in the appendix Figure 4 shown. Figure 4 It is a block diagram of a first communication device 450 and a second communication device 410 that communicate with each other in the access network.

[0227] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmit processor 468, a receive processor 456, and optionally a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter / receiver 454, and an antenna 452.

[0228] The second communication device 410 includes a controller / processor 475, a memory 476, a receive processor 470, a transmit processor 416, and optionally a multi-antenna receive processor 472, a multi-antenna transmit processor 471, a transmitter / receiver 418, and an antenna 420.

[0229] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements the functionality of the L2 (Layer-2) layer. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation for the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). The transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of signal constellations based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital space precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then uses the inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. Subsequently, the multi-antenna transmit processor 471 performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream, and then provides it to different antennas 420.

[0230] In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives signals via its respective antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier, and converts the radio frequency stream into a baseband multi-carrier symbol stream and provides it to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 perform various signal processing functions of the L1 layer. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receivers 454. The receive processor 456 uses the fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receive processor 456, where the reference signal will be used for channel estimation, and the data signal recovers any spatial streams destined for the first communication device 450 after multi-antenna detection in the multi-antenna receive processor 458. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. Subsequently, the receive processor 456 decodes and de-interleaves the soft decisions to recover the upper layer data and control signals transmitted by the second communication device 410 on the physical channel. Subsequently, the upper layer data and control signals are provided to the controller / processor 459. The controller / processor 459 performs the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program code and data. The memory 460 may be referred to as a computer-readable medium. In the transmission from the second communication device 410 to the second communication device 450, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the core network. Subsequently, the upper layer data packets are provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing.

[0231] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, a data source 467 is used to provide an upper layer data packet to a controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function described at the second communication device 410 in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, and implements L2 layer functions for the user plane and the control plane. The controller / processor 459 is also responsible for retransmission of lost packets and signaling to the second communication device 410. A transmit processor 468 performs modulation mapping and channel coding processing, and a multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Subsequently, the transmit processor 468 modulates the generated spatial streams into multi-carrier / single-carrier symbol streams, and after passing through an analog precoding / beamforming operation in the multi-antenna transmit processor 457, provides them to different antennas 452 via a transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and then provides it to the antenna 452.

[0232] In the transmission from the first communication device 450 to the second communication device 410, the functions at the second communication device 410 are similar to the receive function described at the first communication device 450 in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives a radio frequency signal through its corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 jointly implement the functions of the L1 layer. A controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as a computer-readable medium. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover the upper layer data packet from the UE 450. The upper layer data packet from the controller / processor 475 may be provided to the core network.

[0324] As an example, the first value is non - negative.

[0326] As an example, the first value is the size of at least one MAC SDU for the first logical channel.

[0327] As an example, the first value is the size of at least one MAC SDU of the first logical channel associated with the sending of at least one MAC PDU.

[0328] As an example, selecting at least a first logical channel for the first uplink grant includes: whether a logical channel is selected depends on the priority of this logical channel.

[0329] As an example, the priority of the logical channel is network - configured.

[0330] As an example, the priority of the logical channel is configured or indicated by the first signaling.

[0331] As an example, the priority of the logical channel is indicated by DCI.

[0332] As an example, the priority of the logical channel is determined by the priority of a logical channel group.

[0333] As an example, the larger the value of the priority of the logical channel, the lower the priority.

[0334] As an example, selecting at least a first logical channel for the first uplink grant includes: the meaning that whether a logical channel is selected depends on the priority of this logical channel includes: under the condition that parameters other than the priority of the logical channel are the same, the data to be transmitted of the logical channel with a higher logical channel priority is sent first.

[0335] As an embodiment, the selecting of at least a first logical channel for the first uplink grant includes: the meaning that whether a logical channel is selected depends on the priority of this logical channel includes: under the condition that parameters other than the priority of the logical channel are the same, the logical channel with delay-critical data is preferentially transmitted.

[0336] As an embodiment, the act of selecting at least a first logical channel for the first uplink grant includes: whether a logical channel is selected depends on the Bj of this logical channel.

[0337] As an embodiment, the fact that whether a logical channel is selected depends on the Bj of this logical channel includes that when the Bj of this logical channel is greater than a first threshold and the data is delay-critical data or when the Bj of this logical channel is greater than a second threshold, this logical channel is selected.

[0348] As an embodiment, the j is a positive integer.

[0349] As an embodiment, the Bj is a parameter for logical channel priority determination.

[0350] As an example, when a logical channel is established, the MAC entity initializes Bj of this logical channel to 0.

[0351] As an example, for any logical channel j, when performing LCP each time, the MAC entity increases Bj by PBR × T, where T is the time elapsed since Bj was last increased, and PBR is the priority data rate.

[0352] As an example, the PBR of any logical channel is indicated by the network.

[0353] As an example, the PBR of any logical channel is indicated by the first signaling.

[0354] As an example, the upper limit of the first variable is the product of PBR and BSD, where the PBR is the priority data rate and the BSD is the bucket duration.

[0355] As an example, the first variable maintained for the first logical channel is not greater than the upper limit of the first variable.

[0356] As an example, if the first variable is greater than the upper limit of the first variable after the first variable is increased, the first variable is equal to the upper limit of the first variable.

[0357] As an example, when the value of Bj is greater than the size of the bucket, Bj is set to the size of the bucket, where the size of the bucket is equal to PBR × BSD, and the BSD is configured by the network.

[0358] As an example, the advantage of the above method is to avoid high-priority data occupying all resources and preventing low-priority data from being transmitted.

[0359] As an example, for a new transmission, the MAC entity allocates resources according to the following method: for logical channels with Bj greater than 0, allocate resources for the first uplink grant in descending order of priority.

[0360] As an example, if the PBR of one of the at least first logical channels is infinite, all data of this logical channel will be allocated resources before considering logical channels with lower priority.

[0361] As an example, reduce Bj of any logical channel j by the sum of all MAC SDUs (service data units) of the data transmitted on this logical channel j.

[0362] As an embodiment, the first uplink grant selects at least a first logical channel, including: the meaning that whether a logical channel is selected depends on Bj of this logical channel includes: under the condition that parameters other than Bj of the logical channel are the same, the data to be transmitted on the logical channel with a larger Bj is preferentially transmitted.

[0363] As an embodiment, the first uplink grant selects at least a first logical channel, including: the meaning that whether a logical channel is selected depends on Bj of this logical channel includes: under the condition that parameters other than Bj of the logical channel are the same, the data to be transmitted on the logical channel with a smaller Bj is preferentially transmitted.

[0364] As an embodiment, the resource allocation for the data of each logical channel in the at least first logical channel includes: only a part of the data to be transmitted in the target logical channel in the at least first logical channel is allocated resources.

[0365] As an embodiment, the only part is or corresponds to Bj of the target logical channel.

[0366] As an embodiment, the size of the only part is indicated by the first signaling.

[0367] As an embodiment, the action of allocating resources for the data of the at least first logical channel includes: for all other logical channels in the at least first logical channel except the target logical channel, all the data to be transmitted is allocated resources.

[0368] As an embodiment, the target logical channel is the logical channel with the lowest priority in the at least first logical channel.

[0369] As an embodiment, the MAC entity of the terminal maintains a copy of a first variable for each logical channel; whether a logical channel is selected depends on the copy of the first variable of this logical channel.

[0370] As a sub - embodiment of this embodiment, under the condition that other parameters are the same, the larger the copy of the first variable of a logical channel, the more preferentially this logical channel is selected.

[0371] As a sub - embodiment of this embodiment, under the condition that other parameters are the same, the smaller the copy of the first variable of a logical channel, the more preferentially this logical channel is selected.

[0372] As an example, the transmission of at least one MAC PDU depends on the type of the data on the at least first logical channel and the first variable, where at least the latter includes: the transmission of at least one MAC PDU depends on the first variable; the transmission of at least one MAC PDU depends on the type of the data on the at least first logical channel and the first variable.

[0373] As an example, the transmission of at least one MAC PDU depending on the first variable includes: when the first variable is greater than a second threshold, transmitting at least one MAC PDU; when the first variable is not greater than a first threshold, not transmitting at least one MAC PDU.

[0374] As an example, the transmission of at least one MAC PDU depending on the type of the data on the at least first logical channel and the first variable includes: when the type of the data on the at least first logical channel is delay-critical data and the first variable is greater than a first threshold, transmitting at least one MAC PDU; when the type of the data on the at least first logical channel is delay-critical data and the first variable is not greater than a first threshold, not transmitting at least one MAC PDU; when the type of the data on the at least first logical channel is non-delay-critical data and the first variable is greater than a second threshold, transmitting at least one MAC PDU; when the type of the data on the at least first logical channel is non-delay-critical data and the first variable is not greater than a second threshold, not transmitting at least one MAC PDU.

[0375] As an example, the first variable can be negative when transmitting the at least one MAC PDU.

[0376] As an example, the first threshold is a negative number.

[0377] As an example, the first value is a positive number.

[0378] As an example, the first variable can be negative or 0 before decreasing by a first value.

[0379] As an example, if the first variable is less than or equal to the first threshold before decreasing by the first value, the condition for transmitting the at least one MAC PDU is not satisfied, and the at least one MAC PDU cannot be transmitted.

[0380] As an example, for the data type being delay-critical data, if the first variable is greater than the first threshold before decreasing by the first value and less than or equal to the first threshold after decreasing by the first value, the condition for transmitting the at least one MAC PDU is satisfied, and the at least one MAC PDU can be transmitted.

[0381] As an example, the reduction of the first value occurs when preparing to transmit the at least one MAC PDU.

[0382] As an example, the reduction of the first value occurs before allocating resources to the at least one MAC PDU.

[0383] As an example, the reduction of the first value occurs after allocating resources to the at least one MAC PDU for the last time.

[0384] As an example, if the first variable is less than or equal to the first threshold before reducing the first value, resources cannot be allocated to the at least one MAC PDU.

[0385] As an example, the allocation of resources to the at least one MAC PDU is the allocation of uplink grant resources.

[0386] As an example, at least one of the at least one MAC PDU for which resources are allocated comes from the first logical channel selected by the first signaling.

[0387] As an example, the second threshold is 0.

[0388] As an example, the second threshold is greater than 0.

[0389] As an example, the first variable must be greater than 0 before reducing the first value.

[0390] As an example, for the data type that is non-delay-critical data, if the first variable is less than or equal to the second threshold before reducing the first value, the condition for transmitting the at least one MAC PDU is not met, and the at least one MAC PDU cannot be transmitted.

[0391] As an example, for the data type that is non-delay-critical data, if the first variable is greater than the second threshold before reducing the first value and less than or equal to the second threshold after reducing the first value, the condition for transmitting the at least one MAC PDU is met, and the at least one MAC PDU can be transmitted.

[0392] As an example, for the data type that is non-delay-critical data, if the first variable is less than or equal to the second threshold before reducing the first value, resources cannot be allocated to the at least one MAC PDU.

[0413] Example 7

[0414] Embodiment 7 exemplifies a schematic diagram of a first logical channel maintaining a first variable according to an embodiment of the present application, as shown in the appendix Figure 7 shown. In the appendixFigure 7 Among them, the first logical channel is the first logical channel selected by the first uplink grant.

[0415] In Embodiment 7, maintaining a first variable for the first logical channel includes: when the first logical channel is established, the first variable is initialized to 0; in each logical channel priority determination process, the first variable is increased by the product of the PBR and T, where the PBR is the priority data rate and T is the time elapsed since the first variable was last increased; after resources are allocated for the first logical channel, the first variable is decreased by a first value.

[0416] As an embodiment, the first variable is used for the determination of logical channel priority.

[0417] As an embodiment, the first variable is used for the selection of logical channels.

[0418] As an embodiment, the first variable is used for selecting at least the first logical channel for the first uplink grant.

[0419] As an embodiment, the first variable is used for allocating resources for the data of each logical channel in the at least first logical channel.

[0420] As an embodiment, the first variable is Bj.

[0421] As an embodiment, the time when the first variable is updated depends on the implementation of the terminal.

[0422] As an embodiment, the first variable is updated after data is sent on each logical channel.

[0423] As an embodiment, the first variable is updated after a fixed time interval.

[0424] As an embodiment, the first variable is updated before data is sent on each logical channel.

[0425] As an embodiment, each logical channel maintains a first variable.

[0426] As an embodiment, along with the transmission of at least one MAC PDU for the behavior, the value of the first variable is decreased.

[0427] As an embodiment, all MAC PDUs transmitted on the resources of the first uplink grant belong to the at least one MAC PDU.

[0428] As an embodiment, the first value is the size of at least one MAC SDU for the first logical channel.

[0429] As an embodiment, the first value is the size of at least one MAC SDU of the first logical channel associated with sending the at least one MAC PDU.

[0430] As an embodiment, the first value is non - negative.

[0431] As an embodiment, when the data type is delay - critical data, the condition for sending the at least one MAC PDU includes that the first variable must be greater than a first threshold before reducing the first value.

[0432] As an embodiment, the first variable can be negative when sending the at least one MAC PDU.

[0433] As an embodiment, the first threshold is a negative number.

[0434] As an embodiment, the advantage of the first threshold being a negative number is that it can ensure that when the value of the first variable is not negative or too much resources were allocated in the previous transmission, the current transmission can still be sent, thus improving the transmission performance of delay - critical data.

[0435] As an embodiment, the first threshold is a positive number.

[0436] As an embodiment, the first value is a positive number.

[0437] As an embodiment, the first variable can be negative or 0 before reducing the first value.

[0440] As an embodiment, the reduction of the first value occurs when preparing to send the at least one MAC PDU.

[0441] As an embodiment, the reduction of the first value occurs before allocating resources to the at least one MAC PDU.

[0442] As an example, the reduction of the first value occurs after resources are allocated to the last at least one MAC PDU.

[0443] As an example, if the first variable is less than or equal to the first threshold before the first value is reduced, resources cannot be allocated to the at least one MAC PDU.

[0444] As an example, the allocation of resources to the at least one MAC PDU is the allocation of uplink grant resources.

[0445] As an example, at least one of the at least one MAC PDU for which resources are allocated comes from the first logical channel selected by the first signaling.

[0446] As an example, when the data type is non-delay-critical data, the condition for transmitting the at least one MAC PDU includes that the first variable must be greater than the second threshold before the first value is reduced.

[0447] As an example, the second threshold is 0.

[0448] As an example, the second threshold is greater than 0.

[0449] As an example, the advantage of the second threshold being greater than 0 is that for data with lower priority or non-delay-critical data, the first threshold being a positive number can ensure the transmission of other service data / is conducive to avoiding competition for resources with data on high-priority logical channels, especially delay-critical data, can improve efficiency, and avoid fragmentation of data transmission.

[0450] As an example, for the first type of data, the condition for transmitting the at least one MAC PDU includes that the first variable must be greater than the first threshold before the first value is reduced.

[0451] As a sub-example of this example, the first type of data is the data to be transmitted on the logical channel.

[0452] As an example, for the second type of data, the condition for transmitting the at least one MAC PDU includes that the first variable must be greater than the second threshold before the first value is reduced.

[0453] As a sub-example of this example, the second type of data is the data to be transmitted on the logical channel.

[0454] As an example, the first type of data is high-priority data; the second type of data is non-high-priority data.

[0455] As an example, the data of the first type is latency-critical data; the data of the second type is non-latency-critical data.

[0456] As an example, the data of the first type is higher layer signaling; the data of the second type is higher layer data.

[0457] As an example, the data of the first type is high-importance data; the data of the second type is non-high-importance data.

[0458] As an example, the data of the first type is the data of the first SRB; the data of the second type is the data of the second SRB.

[0459] As an example, for the data type that is non-latency-critical data, if the first variable is less than or equal to the second threshold before decreasing the first value, the condition for transmitting the at least one MAC PDU is not satisfied, and the at least one MAC PDU cannot be transmitted.

[0460] As an example, for the data type that is non-latency-critical data, if the first variable is greater than the second threshold before decreasing the first value and less than or equal to the second threshold after decreasing the first value, the condition for transmitting the at least one MAC PDU is satisfied, and the at least one MAC PDU can be transmitted.

[0461] As an example, for the data type that is non-latency-critical data, if the first variable is less than or equal to the second threshold before decreasing the first value, resources cannot be allocated to the at least one MAC PDU.

When there are remaining resources after resource allocation, the first uplink grant selects at least the first logical channel only depending on the priority of the first logical channel, and does not depend on the first variable of the first logical channel.

[0465] As an example, the only part is or corresponds to Bj of the target logical channel.

[0466] As an example, the size of the only part is indicated by the first signaling.

[0467] As an embodiment, the size of only a part is determined by the size of the delay-critical data in the data to be transmitted on the target logical channel.
