Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular, to a data processing method and apparatus in wireless communication. Background Art

[0002] With the continuous development of wireless communication, especially the gradual improvement of the coverage of the fifth-generation mobile communication (5G) new radio (NR) network, 5G will support various types of network deployments and application types, including higher data rate experiences and greater bandwidth access capabilities, lower latency and highly reliable information interaction, larger scale, and low-cost access and management of machine-type communication devices. The connection characteristics of large bandwidth, low latency, and high data rate can meet the requirements of extended reality (XR) services. For example, there are more and more applications such as virtual reality (VR) panoramic videos, VR cloud games, augmented reality (AR), and mixed reality (MR), aiming to create a combined real and virtual, human-computer interactive environment through computer technology and wearable devices. Together with technologies such as 360-degree images, an interactive immersive experience effect is achieved.

[0003] Currently, XR is one of the key 5G multimedia applications considered in the industrial field. A data stream of an XR service may contain data packets of different importance levels. For example, for an XR video service, the differentiated processing requirements of data within the same service flow need to meet layered quality of service (QoS). Although in traditional technical solutions, the logical channel prioritization (LCP) process can map different data to different logical channels for transmission. However, to meet the requirements of the layered QoS of XR services, the traditional LCP process can no longer balance fairness and timeliness.

[0004] Therefore, how to enhance the LCP process has become an urgent problem to be solved. Summary of the Invention

[0005] The inventors of the present application have found through research that in XR services, since the priority of data within a logical channel is no longer distinguished, and there may be delay-critical data within the data. If the priority of the logical channel is increased, but the amount of delay-critical data contained in the data is very small, in the current technical solution, a large amount of non-delay-critical data will be preferentially transmitted, affecting the delay-critical data of other logical channels. Or, if there are multiple PDU sets, and the amount and degree of delay-critical data in each PDU set are different, similar problems will also occur.

[0006] In view of the above problems, the present invention provides an improved technical solution. In the above problem description, the NR system is taken as an example. The present invention is also applicable to scenarios such as the LTE (Long-Term Evolution) system, achieving technical effects similar to those of the NR system. Further, although the original intention of the present invention is for the Uu air interface, the present invention can also be used for the PC5 interface, achieving technical effects similar to those of the Uu air interface. Further, although the original intention of the present invention is for the scenario of terminal devices and base stations, the present invention is also equally applicable to the V2X (Vehicle-to-Everything) scenario, the communication scenarios between terminal devices and relays, and between relays and base stations, achieving technical effects similar to those in the scenario of terminal devices and base stations. Further, although the original intention of the present invention is for the Terrestrial Network (TN) scenario, the present invention is also equally applicable to the communication scenario of the Non-Terrestrial Network (NTN), achieving technical effects similar to those in the TN scenario. In addition, adopting a unified solution for different scenarios helps to reduce hardware complexity and cost.

[0079] As mentioned in the background art, XR services have put forward new requirements for wireless communication systems. The traditional LCP can no longer balance fairness and timeliness. Therefore, scheduling enhancement, such as enhancing the LCP process, is very necessary.

[0080] In the traditional technical solution, when the terminal device obtains a scheduling opportunity, that is, after obtaining the resources for uplink transmission data, it can decide the priority order of serving them according to the conditions of each uplink logical channel. Since the transmission channel capacity allocated to the terminal device within a TTI is limited, the MAC PDU cannot hold all the data packets provided by the logical channels. If the MAC layer entity of the terminal device only relies on the priority to allocate physical layer transmission opportunities for the radio bearers on multiple logical channels, it may cause the logical channels with low priority to never be able to send data.

[0081] The LCP process can ensure that lower-priority logical channels are not starved. Specifically, a network-side device (such as a gNB) sets a Prioritized Bit Rate (PBR) for each uplink logical channel of a terminal device, configures a priority (priority parameter) and a BSD (bucketSizeDuration parameter) for each logical channel. The size of the token bucket for each logical channel is PBR × BSD. The terminal device, based on the MAC layer scheduler, uses the token bucket algorithm to ensure the PBR of the logical channel. For the token bucket of logical channel j (j is a non-negative integer) within time T, the newly added token amount is PBR × T; the total amount of the logical channel j is denoted as Bj; T is the time elapsed since Bj was last incremented.

[0082] Accordingly, the MAC layer scheduler of the terminal device limits the transmission rate of each logical channel to below the PBR. If the data transmission rate of a high-priority logical channel exceeds the PBR, even if there is still data to be sent, the MAC layer scheduler will switch to serving low-priority logical channels that have not reached the PBR.

[0083] In specific implementation, on the terminal device side, tokens are put into the bucket according to the pre-agreed PBR, and each logical channel takes out tokens from the bucket to determine the amount of data to be sent. When the MAC layer scheduler of the terminal device allocates resources, it only considers logical channels with tokens in the bucket, that is, it sends the corresponding data when Bj > 0. If there are still resources afterwards, the resources are re-allocated in the order of priority. Under normal circumstances, the overall operation of the LCP mechanism in the current NR is good, which can ensure meeting the service quality requirements of XR applications.

[0084] However, when the network allocates an uplink (UL) grant to the terminal device and the terminal device has delay-critical data to transmit in the buffer, the terminal device will first select the logical channel with delay-critical data during LCP. Then, the non-delay-critical data in the logical channel with delay-critical data will also be preferentially transmitted, which may affect the scheduling performance of the non-delay-critical data in other logical channels with higher legacy priorities. If the priority of the logical channel is increased, the non-delay-critical data in the logical channel will also be transmitted with a higher priority, which will also affect the scheduling performance of the non-delay-critical data in other LCHs with higher legacy priorities. Therefore, it is very necessary to enhance the LCP process.

[0085] To facilitate the understanding of the embodiments of this application, first, a brief introduction is made to the concepts and technologies involved in the embodiments of the application. It should be understood that the relevant terms and explanations hereinafter are common to all embodiments throughout the text. Different embodiments can be used independently or in combination based on certain internal or external connections. Different implementation manners in the embodiments can be used independently or in combination.

[0086] 1. Service Data Unit (SDU);

[0087] Also known as the service data unit, it is a data set of the user service of a specified layer. After being sent to the next lower layer, the next lower layer encapsulates it in a Protocol Data Unit (PDU) and sends it out.

[0088] 2. Protocol Data Unit;

[0089] For each layer, the information unit from a higher layer is called the SDU of that layer, and the information unit sent to the next lower layer after being processed by that layer is called the PDU of that layer.

[0090] Specifically, the SDU is an information unit that comes from a higher protocol layer and is transmitted to a lower protocol layer. For example, the SDU of the Nth layer and the PDU of the layer above the Nth layer are in one-to-one correspondence. The SDU refers to the amount of information received from the entity of the (N + 1)th layer that has not been processed by the entity of the Nth layer and retains its identification. The PDU refers to a specific data unit at the N protocol layer, including the protocol control information of the N protocol layer and the possible user data of the N protocol layer.

[0091] 3. Medium Access Control (MAC) layer multiplexing;

[0092] Without considering space division multiplexing and carrier aggregation, a terminal device can only send one MAC PDU in a Transmission Time Interval (TTI). Therefore, it is necessary to multiplex the MAC SDUs of multiple logical channels onto the same MAC PDU, which is the origin of MAC layer multiplexing.

[0093] The sending end can multiplex the data of multiple logical channels into one transport channel (TCH) through the multiplexing function of the MAC layer, that is, multiplex multiple MAC SDUs into one MAC PDU and send it out through the physical layer.

[0094] 4. Priority;

[0095] Logical channels serve in the order of priority from high to low.

[0096] 5. Priority Bit Rate (PBR);

[0097] Used to ensure that the service of the relevant logical channel reaches its priority bit rate.

[0098] 6. Logical Channel Limitation;

[0099] Ensure that a certain amount of physical resources are reserved for a given set of logical channels.

[0100] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be noted that, without conflict, the embodiments and features in the embodiments of the present invention can be arbitrarily combined with each other.

[0101] Example 1

[0102] Embodiment 1 exemplifies a signaling flow diagram according to an embodiment of the present invention, as shown in the accompanying Figure 1 drawing. In the accompanying Figure 1 drawing, each box represents a step. It should be particularly emphasized that the order of the boxes in the figure does not represent the chronological relationship between the represented steps.

[0103] In Embodiment 1, the terminal in the present invention may be a terminal device, such as a UE, etc. The method run by the terminal is as follows:

[0104] Step S101, for uplink authorization, allocate resources for at least a part of the delay-critical data to be transmitted in the first logical channel according to the first type of priority;

[0105] Step S102, allocate the remaining resources for at least a part of the remaining data to be transmitted in the first logical channel according to the second type of priority;

[0106] Step S103, send the at least a part of the delay-critical data to be transmitted to the base station;

[0107] Among them, the remaining data to be transmitted includes at least one of delay-critical data and non-delay-critical data.

[0108] Specifically, in step S101, the terminal allocates resources for at least a part of the delay-critical data to be transmitted, and in step S103, sends the at least a part of the delay-critical data to be transmitted to the base station. Among them, the base station may be a network-side device.

[0112] After performing step S101, the remaining data to be transmitted in the first logical channel can be obtained, and the remaining resources of the resources can also be obtained. In other words, the remaining resources are UL resources other than the resources allocated for at least a part of the data to be transmitted with delay criticality in step S101.

[0113] In step S102, the remaining resources can be allocated to the remaining data to be transmitted in the first logical channel according to the second type of priority.

Figure 3 It is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture for controlling plane 300 is shown with three layers: L1, L2, and L3.

[0202] Example 4

[0203] Embodiment 4 exemplifies a schematic diagram of the hardware modules of a communication device according to an embodiment of the present invention, as shown in the appendix Figure 4 as follows. 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 an access network.

[0204] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0205] The second communication device 410 includes a controller / processor 475, a memory 476, a data source 477, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter / receiver 418, and an antenna 420.

[0206] 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 or from the data source 477 are provided to the controller / processor 475. The core network and the data source 477 represent all protocol layers above the L2 layer. The controller / processor 475 implements the functionality of the L2 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 to 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 spatial 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.

[0207] 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 that is provided 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 first communication device 450, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover the upper layer data packets from the second communication device 410. 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.

[0208] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, an upper layer data packet is provided to the controller / processor 459 using the data source 467. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission 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 performs header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels, and implements L2 layer functions for the user plane and the control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the second communication device 410. The transmit processor 468 performs modulation mapping and channel coding processing. The 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 the analog precoding / beamforming operation in the multi-antenna transmit processor 457, provides them to different antennas 452 via the 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.

[0209] 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 receiving functions 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 the multi-antenna receive processor 472 and the receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 jointly implement the L1 layer functions. The 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 first communication device 450. The upper layer data packet from the controller / processor 475 may be provided to the core network or all protocol layers above the L2 layer, and various control signals may also be provided to the core network or L3 for L3 processing.

[0227] Example 5

[0228] Embodiment 5 exemplifies a wireless signal transmission flowchart according to an embodiment of the present invention, as shown in the appendix. Figure 5 Specifically, the order in this example does not limit the signal transmission order and implementation order in the present invention. Among them, step F51 is an optional step.

[0229] For the terminal N51, in step S511, it receives the first signaling, and the first signaling is an RRC signaling. The first signaling is sent by the base station N52, and the base station N52 is the maintaining base station of the source cell. In an embodiment, the base station N52 is also the base station of the serving cell of N51.

[0230] For the base station N52, it sends the first signaling in step S521 and receives at least a part of the data with critical transmission delay in step S522.

[0231] Specifically, in step S512, the terminal N51 allocates resources for at least a part of the delay-critical data to be transmitted in the first logical channel according to the first type of priority for the uplink grant. In step S513, the remaining resources are allocated for at least a part of the remaining data to be transmitted in the first logical channel according to the second type of priority; in step S514, the at least a part of the delay-critical data to be transmitted is sent.

[0232] As an embodiment, the terminal N51 sending the at least a part of the delay-critical data to be transmitted to the base station N52 includes: sending the at least a part of the delay-critical data to be transmitted on the resources allocated for at least a part of the delay-critical data to be transmitted in the first logical channel according to the first type of priority.

[0233] As an embodiment, the remaining data to be transmitted includes delay-critical data.

[0235] As a sub-embodiment, the delay-critical data has different delay criticalities.

[0236] Exemplarily, the delay-critical data has different remaining times.

[0237] As an embodiment, the advantage of the remaining data to be transmitted including delay-critical data is that it can greatly improve the flexibility of resource allocation by the terminal.

[0238] Specifically, the base station N52 may send the first signaling to the terminal N51. In specific implementation, the first may be an RRC signaling. The RRC signaling may indicate the first type of priority of the first logical channel.

[0239] After receiving the RRC signaling, the terminal N51 may store the RRC signaling and obtain the first type of priority.

[0240] As an embodiment, the first signaling may further indicate the token bucket related parameters corresponding to the LCH set.

[0241] In another embodiment, the terminal N51 may receive the token bucket related parameters corresponding to the LCH set configured by the second signaling or the broadcast message.

[0245] As a variant, the first signaling and the second signaling are two different RRC signals.

[0246] As an embodiment, the first logical channel belongs to a logical channel group. The first - type priority of any logical channel in the logical channel group depends on the second - type priority of that logical channel.

[0250] As an embodiment, the second - type priority may refer to the priority in the LCP process in the 3GPP standard protocol TS32.1 Rel - 18 version.

[0251] As a sub - embodiment, the second - type priority is the priority configured by RRC.

[0252] As an embodiment, the logical channel prioritization (LCP) process is applied every time a new transmission is performed. RRC controls the scheduling of uplink data by sending signaling for each logical channel of each MAC entity.

[0253] As an embodiment, the larger the value of the first - type priority, the lower the first - type priority; the larger the value of the second - type priority, the lower the second - type priority.

[0254] As an embodiment, RRC also controls the LCP process by configuring mapping restrictions for each logical channel.

[0256] As an example, maxPUSCH-Duration, if configured, is greater than or equal to the PUSCH transmission duration associated with the UL grant.

[0257] As an example, if configuredGrantType1Allowed is configured, it is set to true when the UL grant is the configured grant type 1.

[0258] As an example, if allowedServingCells is configured, it includes cell information associated with the UL grant (note that this condition does not apply to the logical channels associated with DRBs configured with PDCP duplication within the same MAC entity (i.e., carrier aggregation ("CA") duplication) when CA duplication is deactivated for the DRB in the MAC entity); and

[0259] As an example, allowedCG-List, if configured, includes the configured grant index associated with the UL grant.

[0260] As an example, allowedPHY-PriorityIndex, if configured, includes the priority index associated with the dynamic UL grant.

[0261] As an example, allowedHARQ-mode, if configured, includes the uplink HARQ mode of the HARQ process associated with the UL grant.

[0262] As an example, Bj is a variable maintained for each logical channel j. The MAC entity initializes the maintained Bj to zero when the logical channel is established.

[0263] As an example, the terminal N51 uses the variable Bj for the logical channel prioritization LCP flow: different instances of Bj are maintained for each logical channel j. The MAC entity initializes the variable Bj of the logical channel to zero when the logical channel is established.

[0264] In specific implementation, before each instance of the LCP process, for each logical channel j, the MAC entity increments the value of Bj by the product of PBR×T, where T is the time elapsed since Bj was last incremented.

[0265] If the value of Bj is greater than the bucket size (i.e., PBR×BSD), the MAC entity sets Bj to the bucket size. Note that the exact moment when the UE updates Bj between LCP processes depends on the UE implementation, as long as Bj is up-to-date when the LCP processes the grant.

[0266] Note that when a resource is allocated to logical channel j, the value of Bj can become negative.

[0267] As an example, when a new transmission is to be performed, the MAC entity of terminal N51 selects a logical channel for each UL grant that satisfies all of the following conditions:

[0268] If the subcarrier spacing (SCS) index value allowed in the allowedSCS-List is configured, it includes the subcarrier spacing index related to the UL grant.

[0269] If maxPUSCH-Duration is configured, it shall be no less than the PUSCH transmission duration associated with the uplink (UL) scheduling.

[0270] If configuredGrantType1Allowed is configured, configuredGrantType1Allowed will be set to "true" provided that the UL grant is a configured type 1 (Type1) grant.

[0271] If allowedServingCells is configured, allowedServingCells will include the Cell information associated with the UL grant.

[0272] In the same MAC entity, when CA duplication is disabled for the DRB in that MAC entity, it does not apply to the logical channel associated with that DRB (i.e., PDCP duplication).

[0273] If allowedCG-List is configured, it includes the configured grant index associated with the UL grant.

[0274] If allowedPHY-PriorityIndex is configured, it includes the priority index associated with the dynamic UL grant (as described in Section 9 of TS 38.213 [6]).

[0275] If allowedHARQ-mode is configured, it includes the allowed UL HARQ mode of the HARQ process associated with the UL grant.

[0276] Note: The subcarrier spacing index, PUSCH transmission duration, cell information, and priority index included in the uplink transmission information received from the lower layer are related to the corresponding scheduled uplink transmission.

[0277] As an example, before the random access procedure of Dual Active Protocol Stack (DAPS) handover is successfully completed, the target MAC entity shall not select a logical channel corresponding to a non-DAPS DRB for the uplink grant received in the Random Access Response (RAR) or the uplink grant for transmitting the MSGA payload. The source MAC entity only selects the logical channel corresponding to the DAPS DRB during DAPS handover.

[0278] As an example, the terminal N51 shall also follow the following rules in the above scheduling process:

[0279] If the entire SDU (or a partial transmitted SDU or a retransmitted RLC PDU) can be placed in the remaining resources of the associated MAC entity, the terminal N51 shall not segment the RLC SDU.

[0280] If the UE segments the RLC SDU from the logical channel, it shall make the maximum size of the segments fill the allocation of the associated MAC entity as much as possible.

[0281] The terminal N51 shall maximize data transmission.

[0282] If the MAC entity is allocated a UL allocation size equal to or greater than 8 bytes (when not using eLCID) or 10 bytes (when using eLCID) when there is available data and is allowed to transmit (in accordance with Clause 5.4.3.1), the MAC entity shall not only transmit padding BSR and / or padding.

[0283] As an example, the first logical channel belongs to the first logical channel group, and the PBR of any logical channel in the first logical channel group is not infinite.

[0284] As a sub-example, the radio bearer of the data to be transmitted by the first logical channel is not an SRB.

[0285] As a sub-example, the radio bearer of the data to be transmitted by the first logical channel is a DRB.

[0286] As an example, the first type of priority is a temporary priority set for scheduling the delay-critical data.

[0287] As a sub-example, the temporary priority refers to the LCP-determined priority, but the determined priority is variable when allocating resources.

[0288] As an example, the first type of priority is temporary.

[0289] As an example, the term "temporary" means that the priority is determined each time before LCP or at the time of LCP.

[0290] As an example, any logical channel in at least one logical channel group corresponds to a first type of priority.

[0291] As an example, in at least one logical channel group, there is a logical channel that corresponds to a first type of priority.

[0292] As an example, there is a first logical channel group, and the first logical channel group includes the first logical channel, and the first logical channel corresponds to a first type of priority.

[0293] As an example, the first type of priority of any logical channel depends on the data to be transmitted on that logical channel.

[0294] As a sub - example, the first type of priority is used only when the data to be transmitted on any logical channel includes delay - critical data.

[0295] As a sub - example, the first type of priority of any logical channel is non - zero only when the data to be transmitted on any logical channel includes delay - critical data.

[0296] As an example, the larger the value of the first type of priority, the lower the first type of priority.

[0297] As an example, the first type of priority of any logical channel is equal to the second type of priority of that logical channel + delta, where delta < 0.

[0298] As a variant, for uplink grant, the data to be transmitted by terminal N51 includes the delay - critical data to be transmitted.

[0299] As an example, all the data to be transmitted are delay - critical data.

[0300] As another example, the data to be transmitted includes delay - critical data and non - delay - critical data.

[0301] In one example, the first logical channel transmits the delay - critical data to be transmitted.

[0302] In one example, terminal N51 determines the first variable Bj of the first logical channel. The value of Bj can be greater than 0 or less than 0.

[0303] In specific implementation, the value of Bj can be negative. If the MAC entity of the terminal N51 is requested to transmit multiple MAC PDUs simultaneously, or if the MAC entity receives multiple uplink authorizations in the same or multiple overlapping PDCCH opportunities (i.e., different serving cells), it is determined by the UE implementation in what order to process these uplink authorizations.

[0304] As an embodiment, Bj depends on PBR×T, where T represents the time elapsed since Bj was last incremented.

[0305] As an embodiment, Bj depends on delay critical data.

[0306] As an embodiment, Bj = the product of the rate of delay critical data and T.

[0307] As an embodiment, Bj is less than the data volume of data with a time threshold.

[0308] As an embodiment, Bj is less than the data volume of delay critical data with a time threshold.

[0309] In specific implementation, for UL authorization, determine the first variable Bj of the first logical channel, where Bj>0. Resources are allocated to the data to be transmitted in the first logical channel with Bj>0 in a decreasing priority order.

[0310] Specifically, the terminal N51 allocates the resources to at least a part of the delay critical data to be transmitted in the selected first logical channel with Bj>0 according to the first type of priority.

[0311] As an embodiment, the data volume of the delay critical data to be transmitted is very small. For example, the data volume is less than or equal to the first threshold. Under this condition, the terminal N51 allocates the resources to all the delay critical data to be transmitted in the selected first logical channel with Bj>0 according to the first type of priority.

[0312] As a variant embodiment, the data volume of the delay critical data to be transmitted is large. Under this condition, the terminal N51 allocates the resources to a part of the delay critical data to be transmitted in the selected first logical channel with Bj>0 according to the first type of priority.

[0313] In specific implementation, the data volume of a part of the delay critical data to be transmitted can depend on the implementation of the terminal N1 itself. In one embodiment, according to the current radio environment, such as network temporary congestion or temporary deteriorated channel conditions, the terminal N1 autonomously determines the data volume of a part of the delay critical data to be transmitted.

[0314] In specific implementation, when the MAC entity of terminal N1 performs a new transmission, it can select a logical channel that satisfies the logical channel priority mapping restriction and for which Bj > 0 in the logical channel set to which the logical channel belongs, and allocate resources in the order of decreasing priority of the logical channels. Among them, if the PBR corresponding to the LCH set to which a logical channel belongs is infinite, resources are preferentially allocated to all data to be transmitted on the logical channel.

[0315] Among them, the logical channel priority mapping restriction may refer to: a logical channel that meets the priority requirements, for example, the priority is greater than a predetermined priority.

[0316] In one embodiment, terminal N51 allocates resources for at least one logical channel. Specifically, it may include:

[0317] Terminal N1 selects a logical channel that satisfies the logical channel priority mapping restriction and for which Bj > 0 in the logical channel set to which the logical channel belongs, and allocates resources in the order of decreasing first-class priority of the logical channels. If the PBR of a logical channel is set to infinite, the MAC entity of terminal N51 will allocate resources for all data that can be used for transmission on the logical channel before satisfying the PBR of the lower-priority logical channel.

[0318] Terminal N1 subtracts the total size of the MAC SDUs serving the above logical channel j from Bj.

[0319] If there are any remaining resources after the above initial resource allocation, all selected logical channels are served in the order of strictly decreasing second-class priority (regardless of the value of Bj) until the data of the logical channel is exhausted or the UL grant is exhausted, whichever comes first. Note that logical channels configured with the same priority should be served equally.

[0320] As one embodiment, at least a part of the delay-critical data to be transmitted is carried by the MAC PDU.

[0321] As one embodiment, at least a part of the delay-critical data to be transmitted belongs to the MAC SDU.

[0322] As one embodiment, the remaining resources are the unallocated resources after allocating resources for at least a part of the delay-critical data in the first logical channel according to the first-class priority.

[0323] As one embodiment, each logical channel with delay-critical data to be transmitted has a first-class priority.

[0324] As one embodiment, each logical channel has a second-class priority.

[0325] As an example, the first type of priority of the first logical channel depends on the importance parameter of the delay-critical data to be transmitted.

[0326] In specific implementation, the importance parameter includes the importance parameter and the low importance parameter.

[0327] In specific implementation, if the importance parameter of the delay-critical data to be transmitted is importance, the value of the first type of priority of the first logical channel can be set smaller. Conversely, if the importance parameter of the delay-critical data to be transmitted is low importance, the value of the first type of priority of the first logical channel can be set larger.

[0328] As an example, the first type of priority of the first logical channel depends on the PDU set discard parameter of the delay-critical data to be transmitted.

[0329] As a sub-example, the PDU set discard parameter is pdu-SetDiscard.

[0330] As an example, if the delay-critical data to be transmitted is configured with pdu-SetDiscard, the expiration of the discardtimer of any PDCP SDU belonging to the same PDU set triggers the discarding of all PDUs in the same PDU set.

[0331] As an example, one PDU set carries one unit of application layer data.

[0332] As an example, one PDU set includes at least one PDU. Typically, one PDU set includes multiple PDUs.

[0333] As an example, if the delay-critical data to be transmitted is not configured with pdu-SetDiscard, the expiration of the discardtimer of any PDCP SDU belonging to the same pdu set only triggers the discarding of the any PDCP SDU.

[0334] As an example, the terminal N51 is a user equipment.

[0335] As an example, the terminal N51 is a relay device.

[0336] As an example, the base station N52 is the maintenance node of the first candidate target cell.

[0337] As an example, the base station N52 is one of a TRP, DU, CU, and base station equipment.

[0338] As an embodiment, the base station N52 is a maintenance node for the source cell or serving cell of the terminal N51.

[0340] Example 6

[0341] Embodiment 6 exemplifies a schematic diagram of allocating resources to logical channels according to priorities according to an embodiment of the present application, as shown in the appendix Figure 6 as follows.

[0342] Embodiment 6 illustrates allocating resources to 4 logical channels according to the first type of priority and the second type of priority. The present application does not limit the number of logical channels. In Embodiment 6, the first type of priority of the first logical channel is equal to 1, the first type of priority of the second logical channel is equal to 2, the first type of priority of the third logical channel is equal to 3, and the first type of priority of the fourth logical channel is equal to 4; the second type of priority of the first logical channel is equal to, the second type of priority of the third logical channel is equal to 6, and the second type of priority of the fourth logical channel is equal to 4; the larger the value of the priority, the lower the priority. The above numerical values of the priorities are only illustrative of how to allocate resources according to priorities in the case of different priorities. For how to specifically determine the first type of priority and the second type of priority, reference may be made to other parts of the present application.

[0343] As an embodiment, the first allocation in the appendix Figure 6 refers to: allocating resources to at least a part of the delay-critical data to be transmitted in the first logical channel according to the first type of priority.

[0344] As an embodiment, the second allocation in the appendix Figure 6 refers to: allocating the remaining resources to at least a part of the remaining data to be transmitted in the first logical channel according to the second type of priority.

[0345] As an embodiment, before the first allocation, the data to be transmitted in the first logical channel includes non-delay-critical data and delay-critical data; the data to be transmitted in the second logical channel includes delay-critical data; the data to be transmitted in the third logical channel includes non-delay-critical data and delay-critical data; the data to be transmitted in the fourth logical channel includes non-delay-critical data.

[0346] As an embodiment, in the first allocation, the first logical channel is first allocated resources, followed by the second logical channel, then the third logical channel, and finally the fourth logical channel.

[0347] As an example, in the first allocation, resources are allocated to all the partially delay-critical data and partially non-delay-critical data in the first logical channel.

[0348] As an example, the terminal determines whether to allocate resources to non-delay-critical data in the first allocation according to the amount of remaining resources. For example, when the remaining resources are more than a predetermined threshold, such as more than the resources determined by PBR, or more than 65% of the total resources, resources can be allocated to non-delay-critical data.

[0349] As an example, in the first allocation, resources are allocated to only the delay-critical data among the data to be transmitted in the first logical channel.

[0350] As an example, in the first allocation, resources can be allocated to both only the delay-critical data and non-delay-critical data among the data to be transmitted in the first logical channel.

[0351] As an example, in the first allocation, resources are allocated to the delay-critical data in the second logical channel.

[0352] As a sub-example of this example, in the first allocation, all the delay-critical data in the second logical channel are allocated resources.

[0353] As an example, in the first allocation, resources are allocated to only the delay-critical data in the third logical channel.

[0354] As an example, in the first allocation, no resources are allocated to the fourth logical channel.

[0355] As an example, when the data to be transmitted in a logical channel does not include delay-critical data, the first type of priority of the logical channel is equal to the second type of priority.

[0356] As an example, when the data to be transmitted in a logical channel does not include delay-critical data, the logical channel does not participate in the first allocation.

[0357] As an example, in the second allocation, the fourth logical channel is allocated resources limitedly, then the first logical channel, and finally the third logical channel.

[0358] As an example, in the second allocation, some non-delay-critical data in the fourth logical channel are allocated resources.

[0359] As an example, in the second allocation, some non-delay-critical data in the first logical channel are allocated resources.

[0360] As an example, in the second allocation, all the latency-critical data and some of the non-latency-critical data of the third logical channel are allocated resources.

[0361] As an example, in the second allocation, the latency-critical data of any logical channel does not have priority over the non-latency-critical data of the same logical channel.

[0362] As an example, in the second allocation, the latency-critical data of any logical channel has priority over the non-latency-critical data of the same logical channel.

[0363] As an example, in the second allocation, whether the latency-critical data of any logical channel has priority over the non-latency-critical data of the same logical channel depends on the implementation of the terminal.

[0364] As an example, if the first-class priorities of two logical channels are equal, the non-latency-critical data of one logical channel will not be allocated resources until the latency-critical data that still needs to be transmitted of the other logical channel is to be allocated resources.

[0365] As an example, if the second-class priorities of two logical channels are equal, the non-latency-critical data of one logical channel will not be allocated resources until the latency-critical data that still needs to be transmitted of the other logical channel is to be allocated resources.

[0366] As an example, if the second-class priorities of two logical channels are equal, the non-latency-critical data of one logical channel may be allocated resources before the latency-critical data that still needs to be transmitted of the other logical channel is to be allocated resources.

[0367] As an example, if the second-class priorities of two logical channels are equal, whether the non-latency-critical data of one logical channel is allocated resources depends on the implementation of the terminal until the latency-critical data that still needs to be transmitted of the other logical channel is to be allocated resources.

[0368] Example 7

[0369] Example 7 illustrates a schematic diagram for determining the first-class priority according to the second-class priority according to an embodiment of the present application, as shown in the appendix Figure 7 as shown.

[0370] As an example, the first-class priority of any logical channel is derived from the second-class priority of the same logical channel.

[0371] As an example, the first-class priority of any logical channel is not lower than the second-class priority of the same logical channel.

[0372] As an embodiment, the first type of priority of the first logical channel is derived from the second type of priority of the first logical channel.

[0373] As an embodiment, the first type of priority of the first logical channel is not lower than the second type of priority of the first logical channel.

[0374] As an embodiment, the value of the first type of priority of the first logical channel is less than the value of the second type of priority of the first logical channel.

[0375] As an embodiment, the first type of priority of the first logical channel is higher than the second type of priority of the first logical channel.

[0376] As an embodiment, the value of the first type of priority of the first logical channel is equal to the sum of the value of the second type of priority of the first logical channel and D1.

[0377] As a sub - embodiment of this embodiment, D1 is a negative number.

[0378] As a sub - embodiment of this embodiment, D1 is an integer.

[0379] As an embodiment, D1 depends on the remaining time of the first data in the delay - critical data of the data to be transmitted on the first logical channel.

[0380] As a sub - embodiment of this embodiment, the first data is the data with the minimum remaining time among the data to be transmitted on the first logical channel.

[0381] As a sub - embodiment of this embodiment, the first data is the data with the minimum remaining time among the data with a remaining time greater than the first specific threshold in the data to be transmitted on the first logical channel.

[0382] As a sub - embodiment of this embodiment, the first specific threshold is network - configured.

[0383] As an embodiment, there is a mapping relationship between D1 and the remaining time of the first data.

[0384] As an embodiment, there is a reciprocal relationship between D1 and the remaining time of the first data.

[0385] As an embodiment, D1 is a fixed value.

[0386] As an embodiment, D1 is network - configured.

[0387] As an embodiment, D1 depends on whether the delay - critical data to be transmitted on the first logical channel is configured with pdu - setDiscard.

[0388] As an embodiment, whether the D1 depends on whether the delay-critical data to be transmitted on the first logical channel is configured with pdu-setDiscard includes: when the delay-critical data to be transmitted on the first logical channel is configured with pdu-setDiscard, the first D1 is a first candidate value; when the delay-critical data to be transmitted on the first logical channel is not configured with pdu-setDiscard, the first D1 is a second candidate value.

[0389] As an embodiment, the first candidate value and the second candidate value are network-configured.

[0390] As an embodiment, the value of the D1 is for a specific logical channel.

[0391] As an embodiment, the D1 is for all logical channels.
