Description

Technical Field

[0001] This application relates to methods and apparatuses in a wireless communication system, and particularly to methods and apparatuses for supporting a Logical Channel Prioritization (LCP) process in wireless communication. 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 Partner Project) RAN (Radio Access Network) to conduct research on the New Radio (NR) (or 5G) technology. At the 75th plenary session of 3GPP RAN, the WI (Work Item) of the New Radio technology was approved, and the standardization work of NR began.

[0003] FD (Full Duplex) can significantly improve spectral efficiency and thus become a research hotspot, among which SBFD (SubBand non-overlapping Full Duplex) has particularly attracted the research interest of the industry.

[0004] The logical channel prioritization process is used to select logical channels in uplink transmission. With the introduction of new services and the application of various new radio technologies, the logical channel prioritization process has been evolving and is also an important feature of future 5G, 5G evolution, and 6G radio access. Summary of the Invention

Without conflict, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

In addition, adopting a unified solution for different scenarios helps to reduce hardware complexity or improve compatibility. Without conflict, the embodiments and features in the embodiments of any node in this application can be applied to any other node. In particular, the explanations of the terms, nouns, functions, and variables in this application (if not otherwise specified) can refer to the definitions in the 3GPP specification protocols TS38 series and TS37 series.

[0136] As an example, at least one logical channel is composed of logical channels that satisfy a first set of conditions and have Bj greater than 0, selected from the first set of logical channels according to at least one parameter in the first set of parameters.

[0181] Embodiment 3 exemplifies a schematic diagram of the radio protocol architecture of the user plane and the control plane according to an embodiment of this application, as shown in the appendix Figure 3 as follows. Figure 3 It is a schematic diagram illustrating an embodiment of the radio protocol architecture for the user plane 350 and the control plane 300, Figure 3The radio protocol architecture of the control plane 300 of the UE and gNB 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. Layer 1 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 UE and gNB through PHY 301. Layer 2 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, and these sublayers terminate at the gNB on the network side. The PDCP sublayer 304 provides data encryption and integrity protection, and the PDCP sublayer 304 also provides handover support for the UE between gNBs. The RLC sublayer 303 provides segmentation and reassembly of data packets, retransmission of lost data packets through ARQ, and the RLC sublayer 303 also provides duplicate packet detection and protocol error detection. The MAC sublayer 302 provides the mapping between logical and transport channels and the multiplexing of logical channel identities. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell among UEs. The MAC sublayer 302 is also responsible for HARQ (Hybrid Automatic Repeat Request) operations. The RRC (Radio Resource Control) sublayer 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 gNB and the UE. The radio protocol architecture of the user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). The radio protocol architecture in the user plane 350 is generally the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, the RLC sublayer 353 in the L2 layer 355, and the MAC sublayer 352 in the L2 layer 355, but the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead. The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356, and the SDAP sublayer 356 is responsible for the mapping between QoS flows and data radio bearers (DRBs, Data Radio Bearer) to support service diversity. The radio protocol architecture of the UE in the user plane 350 may include some or all of the protocol sublayers of the SDAP sublayer 356, the PDCP sublayer 354, the RLC sublayer 353, and the MAC sublayer 352 in the L2 layer.Although not shown, the UE may also have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) that terminates at the P-GW on the network side and an application layer that terminates at the other end of the connection (e.g., a remote UE, a server, etc.).

[0206] Example 4

[0207] Example 4 exemplifies a schematic diagram of the hardware modules of a communication device according to an embodiment of this application, as shown in the appendix Figure 4 as shown. Figure 4 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.

[0208] 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, a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter / receiver 454, and an antenna 452.

[0209] The second communication device 410 includes a controller / processor 475, a memory 476, a data source 477, a receive processor 470, a transmit processor 416, a multi-antenna receive processor 472, a multi-antenna transmit processor 471, a transmitter / receiver 418, and an antenna 420.

[0210] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, an upper-layer data packet from the core network or an upper-layer data packet from the data source 477 is 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 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.

[0211] 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 multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover higher 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.

[0212] 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 implements 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 stream into a multi-carrier / single-carrier symbol stream, and after passing through the analog precoding / beamforming operation in the multi-antenna transmit processor 457, it is provided 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.

[0213] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the reception 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 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 functions of the L1 layer. 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.

[0312] Example 7

[0313] Embodiment 7 exemplifies the signal - processing flowchart in the first node according to an embodiment of the present application, as shown in the appendix Figure 7 as follows.

[0314] In Embodiment 7, the first node determines in step S701 whether the first radio bearer is configured with PDCP duplication and whether the PDCP duplication is activated. If so, step S702 is executed; if not, step S703 is executed. In step S702, it is determined that the first type of parameters of the first logical channel is applied. In step S703, it is determined that the first type of parameters of the first logical channel is not applied. In step S704, at least one logical channel is selected from the first logical channel set according to at least one parameter in the first parameter set.

[0315] As an embodiment, whether the first type of parameters of the first logical channel is applied depends on whether the first radio bearer is configured with PDCP duplication and whether the PDCP duplication is activated. Among them, the first logical channel is associated with the first radio bearer.

[0316] As an embodiment, it is determined whether the first type of parameters of the first logical channel is applied according to whether the first radio bearer is configured with PDCP duplication and whether the PDCP duplication is activated.

[0317] As an embodiment, when the first radio bearer is configured with PDCP duplication and the PDCP duplication is activated, the first type of parameters of the first logical channel is applied. As an embodiment, when the first radio bearer is configured with PDCP duplication and the PDCP duplication is activated, a PDCP data packet of the first radio bearer is transmitted through multiple paths.

[0318] As an embodiment, when the first radio bearer is configured with PDCP duplication and the PDCP duplication is activated, a PDCP entity of the first radio bearer is associated with multiple RLC entity transmissions.

[0319] As an embodiment, the first logical channel is one of the multiple logical channels associated with the first radio bearer.

[0320] As an embodiment, the first radio bearer is a Data Radio Bearer (DRB).

[0321] As an embodiment, the first radio bearer is a Signaling Radio Bearer (SRB).

[0322] As an embodiment, the first radio bearer is a Multicast / Broadcast Service Radio Bearer (MBS RadioBearer, MRB).

[0323] As an example, the first radio bearer is configured with PDCP duplication and the PDCP duplication is activated, and the first parameter of the first logical channel is applied.

[0324] As an example, when the first radio bearer is configured with PDCP duplication and the PDCP duplication is activated, a PDCP data packet of the first radio bearer is copied and sent through at least two RLC entities.

[0325] As an example, the symbol type included in the first type of parameters configured for one logical channel associated with the first radio bearer is different from the symbol type included in the first type of parameters configured for other logical channels associated with the first radio bearer.

[0326] As an example, the symbol type included in the first type of parameters configured for one logical channel associated with the first radio bearer is orthogonal to the symbol type included in the first type of parameters configured for other logical channels associated with the first radio bearer.

[0327] As an example, the symbol type included in the first type of parameters configured for one logical channel associated with the first radio bearer includes at least one symbol type that does not belong to the symbol type included in the first type of parameters configured for other logical channels associated with the first radio bearer.

[0328] The above three examples can ensure that PDCP data packets are sent using different symbol types on different paths, which can improve transmission reliability and avoid using the same symbol type for transmission on multiple paths, thus unable to obtain the combining gain.

[0329] Specifically, the first radio bearer is associated with two logical channels, namely logical channel 1 and logical channel 2. The first type of parameters configured for logical channel 1 indicate the SBFD symbol, and the first type of parameters configured for logical channel 2 indicate only non - SBFD symbols. When the type of the symbol included in the time - domain resource indicated by the first UL grant is the SBFD symbol, logical channel 1 can be selected and logical channel 2 cannot be selected; when the type of the symbol included in the time - domain resource indicated by the first UL grant is the non - SBFD symbol, logical channel 2 can be selected; the duplication of the data packets of the first radio bearer is sent through different symbol types, which can effectively avoid transmission failures caused by strong interference on one type of symbol and can obtain the combining gain.

[0330] As an example, when the first radio bearer is configured with PDCP duplication and the PDCP duplication is not activated, the first type of parameters of the first logical channel are not applied.

[0331] As an example, when the first radio bearer is not configured with PDCP duplication, the first type of parameters of the first logical channel are not applied.

[0332] As a sub - example of the above two examples, the above method can be backward - compatible and can reduce the implementation complexity.

[0333] As an example, the PDCP duplication is at least one of PDCP CA (Carrier Aggregation) duplication or PDCP DC (Dual Connectivity) duplication.

[0334] As a sub - example of the above example, the locations of the at least two RLC entities used for PDCP duplication are used to determine whether the PDCP duplication is PDCP CA duplication, PDCP DC duplication, or both PDCP CA duplication and PDCP DC duplication.

[0335] As an example, the PDCP duplication is PDCP CA duplication and the PDCP duplication is activated.

[0336] As a sub - example of the above example, the same PDCP data packet is sent over the air through different carriers.

[0337] As a sub - example of the above example, the same PDCP data packet is associated with at least two RLC entities for transmission, and the at least two RLC entities are located within the same base station.

[0338] As an example, the PDCP duplication is PDCP DC duplication and the PDCP duplication is activated.

[0339] As a sub - example of the above example, the same PDCP data packet is sent over the air through cells maintained by different base stations.

[0340] As a sub - example of the above example, the same PDCP data packet is associated with at least two RLC entities for transmission, and the at least two RLC entities are located in different base stations respectively.

[0341] As an example, the PDCP duplication is both PDCP CA duplication and PDCP DC duplication, and the PDCP duplication is activated.

[0342] As a sub - example of the above example, the same PDCP data packet is sent over the air both through different carriers and through cells maintained by different base stations.

[0343] As a sub - embodiment of the above - mentioned embodiment, the same PDCP data packet is associated with at least three RLC entities for transmission, where at least two of the at least three RLC entities are located within the same base station, and at least two of the at least three RLC entities are located in different base stations.

[0344] Example 8

[0345] Embodiment 8 exemplifies the signal - processing flowchart in a first node according to an embodiment of the present application, as shown in the appendix Figure 8 as follows.

[0346] In Embodiment 8, the first node determines in step S801 whether the type of the symbol included in the time - domain resource indicated by the first UL grant is an SBFD symbol. If so, step S802 is executed; if not, step S804 is executed. In step S802, it is determined whether the first radio bearer is configured with PDCP duplication and whether the PDCP duplication is activated. If so, step S803 is executed; if not, step S804 is executed. In step S803, it is determined that the first - type parameters of the first logical channel are applied. In step S804, it is determined that the first - type parameters of the first logical channel are not applied. In step S805, at least one logical channel is selected from the first logical - channel set according to at least one parameter in the first parameter set.

[0347] As an embodiment, whether the first - type parameters of the first logical channel are applied depends on the type of the symbol included in the time - domain resource indicated by the first UL grant, and whether the first - type parameters of the first logical channel are applied also depends on whether the first radio bearer is configured with the PDCP duplication and whether the PDCP duplication is activated.

[0348] Specifically, the first radio bearer is associated with two logical channels, namely logical channel 1 and logical channel 2. The first type of parameters configured for logical channel 1 indicate the SBFD symbols, and the first type of parameters configured for logical channel 2 indicate only the non-SBFD symbols. When the type of the symbols included in the time domain resources indicated by the first UL grant is the non-SBFD symbol, neither the first type of parameters of logical channel 1 nor the first type of parameters of logical channel 2 are applied, that is, both logical channel 1 and logical channel 2 can be selected; when the type of the symbols included in the time domain resources indicated by the first UL grant is the SBFD symbol, logical channel 1 can be selected and logical channel 2 cannot be selected; the replication of the data packets of the first radio bearer is sent through different symbol types, which can effectively avoid transmission failures caused by strong interference occurring on a certain type of symbols and can obtain a combining gain.

[0349] The above method can further reduce the latency of high-reliability and low-latency services and improve transmission reliability.
