Description

Technical Field

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, and particularly to a method and apparatus for resource allocation. 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, R18 has enhanced for XR services. The 3GPP (the 3rd Generation Partnership Project) RAN (Radio Access Network) #103 meeting decided to launch the "NR (New Radio) XR (Extended Reality) Phase 3" Work Item (WI), aiming to provide efficient and effective scheduling to improve system capacity. For example, the time limit for resource allocation is relaxed as much as possible while meeting the latency requirements or avoiding too late PDUs (Protocol Data Units). Among them, solving this problem through UE (User Equipment) Logical Channel Prioritization (LCP) and rate enforcement / avoidance of starvation is a research direction.

[0003] In the prior art, the LCP process is used to allocate resources, and the LCP process is applied whenever a new transmission is performed. Among them, a Bj is maintained for each logical channel; the initial value of Bj is 0, and before each execution of the LCP process, Bj is increased by PBR (Prioritized Bit Rate) × T; the logical channels with Bj greater than 0 will be preferentially allocated resources, and after being allocated resources, Bj is decreased; if there are still remaining resources, Bj is ignored, and resources are allocated to logical channels in descending order of strict priority, and logical channels with the same priority should receive the same service. Summary of the Invention

[0004] The applicant has found through research that the mechanism of preferentially allocating resources in the existing resource allocation is not conducive to the timely transmission of delay-critical data, thus affecting system performance. Therefore, it is necessary to enhance the preferential allocation of resources.

[0005] In view of 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), future 5G+ or 6G systems, and achieves technical effects similar to those of the NR system. Further, although the original intention of the present application is for XR, the present application can also be used for the transmission of other services with higher priorities and achieve technical effects similar to those of XR. 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 and achieve technical effects similar to those of the Uu air interface. Further, although the original intention of the present application is for the scenario of the terminal and the base station, the present application is also applicable to the V2X (Vehicle-to-Everything) scenario, the communication scenarios between the terminal and the relay, and between the relay and the base station, and achieves technical effects similar to those in the scenario of the terminal and the base station. Further, although the original intention of the present application is for the scenario of the terminal and the base station, the present application is also applicable to the communication scenario of IAB (Integrated Access and Backhaul) and achieves technical effects similar to those in the scenario of the terminal and the base station. Further, although the original intention of the present application is for the terrestrial network (TN) scenario, the present application is also applicable to the communication scenario of the non-terrestrial network (NTN) and achieves technical effects similar to those in the TN scenario. In addition, adopting a unified solution for different scenarios helps to reduce the hardware complexity and cost.

[0006] As an embodiment, the interpretation of the terms in the present application refers to the definitions in the 3GPP specification protocol series TS38.

[0007] As an embodiment, the interpretation of the terms in the present application refers to the definitions in the 3GPP specification protocol series TS37.

[0008] It should be noted that, without conflict, the embodiments and features in the terminal of the present application can be applied to the base station. Without conflict, the embodiments and features in the base station of the present application can be applied to the terminal. Without conflict, the embodiments and features in the present application can be arbitrarily combined with each other.

[0009] The present application discloses a method applied to a terminal, characterized by including:

[0010] Receiving a first signaling; wherein, the first signaling indicates a first logical channel;

[0011] Before the resource prioritization allocation in the first LCP (Logical Channel Prioritization) process, set Bj of the first logical channel to a first value; wherein, the first value is greater than 0;

[0012] Wherein, setting Bj of the first logical channel to the first value depends on at least that Bj of the first logical channel is not greater than a first threshold, and the first threshold is not less than 0.

[0013] In the existing resource allocation, only the logical channels with Bj greater than 0 will be prioritized for resource allocation, and the total amount of the prioritized resources does not exceed Bj. If Bj is not greater than 0, it may lead to the inability to allocate resources in a timely manner. The above method makes Bj of the first logical channel greater than 0 in the resource allocation of the first LCP process, thus ensuring that the data on the first logical channel is sent first, which is beneficial to improving the transmission performance of the data that temporarily needs to improve the priority.

[0014] According to one aspect of the present application, it is characterized in that,

[0015] Setting Bj of the first logical channel to the first value also depends on the second LCP process;

[0016] Wherein, the second LCP process is before the first LCP process.

[0017] The above method considers that if the data of this logical channel is not allocated enough resources in one LCP process and Bj of this logical channel is not greater than 0 in the next LCP, this logical channel will not be prioritized for resource allocation. If the service cannot be obtained in a timely manner, it will lead to more serious delay of this logical channel. The above method ensures the transmission of the remaining data in one LCP process by setting Bj of the first logical channel to the first value also depending on the second LCP process.

[0018] The above method is beneficial to network control and reduces the unnecessary logical channels from being prioritized for resource allocation.

[0019] According to one aspect of the present application, it is characterized in that,

[0020] The first threshold depends on at least the data volume of the first type of data on the first logical channel; the first signaling indicates the first type.

[0025] According to one aspect of the present application, it is characterized in that

[0026] The first threshold depends on the bucket size of the first logical channel.

[0027] The above method helps to avoid affecting other logical channels.

[0028] The above method is conducive to the fairness of resource allocation.

[0029] According to one aspect of the present application, it is characterized in that

[0030] The first value depends on the bucket size of the first logical channel.

[0033] According to one aspect of the present application, it is characterized in that

[0034] The first value is not less than the first threshold.

[0035] The above method further restricts the first value and the first threshold, ensuring that by setting Bj of the first logical channel to the first value, Bj of the first logical channel is set from a smaller value to a larger value, avoiding meaningless operations.

[0036] According to one aspect of the present application, it is characterized in that

[0037] After the first LCP process, a first MAC (Medium Access Control) PDU is generated and sent;

[0042] According to one aspect of the present application, it is characterized in that

[0043] Setting the Bj of the first logical channel to the first value also depends on a second LCP process;

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: 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 PHY301 herein. Layer 2 (L2 layer) 305 is above PHY301 and includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304.

[0213] Example 4

[0214] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to this application, as shown in the appendix Figure 4 as 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 an access network.

[0215] 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.

[0216] The second communication device 410 includes a controller / processor 475, a memory 476, 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.

[0217] 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. 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 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.

[0218] 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 corresponding 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 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 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.

[0219] 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 upper layer data packets 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. 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 a multi-carrier / single-carrier symbol stream, and after an analog precoding / beamforming operation in the multi-antenna transmit processor 457, provides the symbol stream 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.

[0220] 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 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 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 L1 layer functions. 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 upper layer data packets from the UE 450.
