Abstract

This application discloses a method and apparatus for a node used in wireless communication. The node receives a first information block, which is used to determine a first β value. The node determines a high-level HARQ bit block and a low-level HARQ bit block and transmits a target PUSCH, the target PUSCH carrying the high-level HARQ bit block and the low-level HARQ bit block. The high-level HARQ bit block generates a high-level reference bit block, and the first β value is used to determine the number of modulation symbols generated by the high-level HARQ bit block. When the target PUSCH is only used to carry HARQ-ACK, the number of HARQ-ACK bits included in the high-level HARQ bit block is used to determine whether the high-level reference bit block includes bits other than those in the high-level HARQ bit block. When the target PUSCH is also used to carry information bits other than HARQ-ACK, the high-level reference bit block and the high-level HARQ bit block are the same. This application improves the resource utilization of the PUSCH.

Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to transmission schemes and apparatus for uplink control information with high and low priority levels in wireless communication. Background Technology

[0002] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place different performance requirements on the system. To meet the diverse performance needs of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting decided to conduct research on New Radio (NR) (or 5G). The 3GPP RAN #75 plenary meeting approved the WI (Work Item) for NR, initiating standardization work for NR. The 3GPP RAN #86 plenary meeting decided to begin work on the SI (Study Item) and WI (Work Item) for NR Rel-17.

[0003] In new air interface technologies, enhanced mobile broadband (eMBB), ultra-reliable and low-latency communications (URLLC), and massive machine-type communications (mMTC) are three main application scenarios. Summary of the Invention

[0004] In URLLC communication, data or control information with different priority levels can be transmitted. In NR Rel-16, when UCIs (Uplink Control Information) with different priority levels collide in the time domain, the lower-priority UCI is abandoned to ensure the transmission of the higher-priority UCI. In NR Rel-17, multiplexing UCIs with different priority levels onto the same PUSCH is supported.

[0005] To address the issue of multiplexing UCIs associated with different priority levels onto the same PUSCH, this application discloses a solution. It should be noted that URLLC is described in this application only as a typical application scenario or example; this application is also applicable to other scenarios facing similar problems (e.g., scenarios with multiple services coexisting, or scenarios with multiplexing of information with different priority levels, or scenarios with multiplexing of services with different QoS requirements, or scenarios for different application scenarios, such as vehicle-to-everything (V2X) and eMBB multiplexing), and can achieve similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to URLLC scenarios) helps reduce hardware complexity and cost. Where there is no conflict, the embodiments and features in the first node device of this application can be applied to the second node device, and vice versa. In particular, the interpretation of terms, nouns, functions, and variables in this application (unless otherwise specified) can be found in the definitions in the 3GPP specification protocols TS36, TS38, and TS37 series.

[0006] This application discloses a method for a first node in wireless communication, characterized by comprising:

[0007] Receive a first information block, which is used to determine a first β value, wherein the first β value is a non-negative number;

[0008] Determine the high-level HARQ bit block and the low-level HARQ bit block and send the target PUSCH, which is used to carry the high-level HARQ bit block and the low-level HARQ bit block;

[0009] The high-priority HARQ bit block includes at least one high-priority HARQ-ACK bit, and the low-priority HARQ bit block includes at least one low-priority HARQ-ACK bit. The high-priority HARQ bit block is used to generate a high-priority reference bit block, which includes multiple bits. The first β value is used to determine the number of modulation symbols generated by the high-priority HARQ bit block. When the target PUSCH is only used to carry HARQ-ACK, the number of HARQ-ACK bits included in the high-priority HARQ bit block is used to determine whether the high-priority reference bit block includes bits other than those in the high-priority HARQ bit block. When the target PUSCH is also used to carry information bits other than HARQ-ACK, the high-priority reference bit block is the same as the high-priority HARQ bit block.

[0010] As an example, whether the target PUSCH is only used to carry HARQ-ACK is used as the criterion for whether to fill bits for high-priority HARQ-ACK. This supports the design of a reserved RE method when high and low priority HARQ-ACK are multiplexed on the same PUSCH, avoiding the waste of reserved RE and ensuring the resource utilization when controlled multiplexing on PUSCH.

[0011] According to one aspect of this application, the above method is characterized in that, when the target PUSCH is used only to carry HARQ-ACK bits and the number of HARQ-ACK bits included in the high-level HARQ bit block is less than 2, the high-level HARQ bit block is padded with "0" bits to generate the high-level reference bit block; when the target PUSCH is used only to carry HARQ-ACK bits and the number of HARQ-ACK bits included in the high-level HARQ bit block is not less than 2, the high-level reference bit block and the high-level HARQ bit block are the same.

[0012] According to one aspect of this application, the method is characterized in that the time-frequency resources occupied by the target PUSCH include a first time-frequency resource, the first time-frequency resource block being reserved for HARQ-ACK, the first time-frequency resource block including at least one RE; the first β value and the high-level reference quantity value are used together to determine the number of REs included in the first time-frequency resource block, the number of bits included in the high-level reference bit block being equal to the high-level reference quantity value; when the number of HARQ-ACK bits included in the high-level HARQ bit block is not greater than 2, any RE mapped by the modulation symbol generated by the low-level HARQ bit block is orthogonal to the first time-frequency resource block.

[0013] As an example, existing channel encoders are reused as much as possible when reserved REs are occupied, which reduces the implementation complexity under different multiplexing conditions. At the same time, different β offset values ​​are used to determine the number of reserved REs according to different conditions. This reduces the adverse effects caused by the ambiguity of the number of HARQ-ACK bits and optimizes the use of time and frequency resources as much as possible, thereby further improving the utilization rate of resources on PUSCH.

[0014] According to one aspect of this application, the method is characterized in that the first information block is used to determine a second β value, the second β value being a non-negative number; when the number of HARQ-ACK bits included in the low-level HARQ bit block is not greater than 2, the low-level HARQ bit block is used to generate a low-level reference bit block, the low-level reference bit block including multiple bits, the number of bits included in the low-level reference bit block being equal to a low-level reference quantity value, the low-level reference quantity value being greater than 2, the second β value and the low-level reference quantity value together being used to determine the number of modulation symbols generated by the low-level HARQ bit block; when the number of HARQ-ACK bits included in the low-level HARQ bit block is greater than 2, the second β value and the number of HARQ-ACK bits included in the low-level HARQ bit block together being used to determine the number of modulation symbols generated by the low-level HARQ bit block.

[0015] As an example, when high and low level HARQ-ACKs are multiplexed together on the PUSCH, the length of the output bit sequence after rate matching is calculated based on the number of bits of the padded low-level HARQ-ACK. At the same time, the existing resource (RE) mapping of CSI part 1 is reused. This reduces the complexity of implementation, makes rate matching and resource mapping more compatible, and reduces the impact caused by the ambiguity of the number of low-level HARQ-ACK bits.

[0016] According to one aspect of this application, the above method is characterized by comprising:

[0017] Receive the first signaling;

[0018] Wherein, the first signaling is used to determine the time-frequency resources occupied by the target PUSCH; the priority level corresponding to the target PUSCH and the first information block are used together to determine Y1 sets of β values; any β value set in the Y1 sets of β values ​​includes multiple candidate β values, any candidate β value included in any β value set in the Y1 sets of β values ​​is a non-negative number, and Y1 is a positive integer greater than 1; the first signaling is used to determine a first set of β values ​​from the Y1 sets of β values, the first β value is equal to one candidate β value included in the first set of β values, and the number of HARQ-ACK bits included in the high-level HARQ bit block is used to determine the first β value from the first set of β values.

[0019] As an example, different sets of β offset values ​​are used depending on whether HARQ-ACK with different priority levels is reused and the number of bits of HARQ-ACK reused, so that the effective code rate of the configured UCI meets the robustness requirements under different conditions and ensures the transmission performance of HARQ-ACK in URLLC.

[0020] According to one aspect of this application, the above method is characterized in that the scheduling signaling of the target PUSCH includes a first field, the value of which is a non-negative integer; the value of the first field is used to determine the number of HARQ-ACK bits included in the low-level HARQ bit block.

As shown in the figure, 5GS / EPS provides packet-switched services; however, those skilled in the art will readily understand that the various concepts presented throughout this application can be extended to networks providing circuit-switched services or other cellular networks.

Figure 3 As shown. Figure 3 This 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 the control plane 300 between the first node device (UE or gNB) and the second node device (gNB or UE) is illustrated using 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. L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the first and second node devices via PHY301. L2 layer 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security through encrypted data packets and supports cross-regional mobility between the second node devices and the first node device. RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among first-node devices. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the second-node devices and the first-node devices. The radio protocol architecture of user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). The radio protocol architecture for the first and second node devices in user plane 350 is largely the same as the corresponding layers and sublayers in control plane 300 for Physical Layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355, and MAC sublayer 352 in L2 layer 355. However, PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead. L2 layer 355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS flows and Data Radio Bearers (DRBs) to support service diversity.Although not illustrated, the first node device may have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., remote UE, server, etc.).

[0206] Example 4

[0207] Example 4 illustrates a schematic diagram of a first node device and a second node device according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown.

[0208] The first node device (450) may include a controller / processor 490, a data source / buffer 480, a receiver processor 452, a transmitter / receiver 456 and a transmitter processor 455, wherein the transmitter / receiver 456 includes an antenna 460.

[0209] The second node device (410) may include a controller / processor 440, a data source / buffer 430, a receiver processor 412, a transmitter / receiver 416 and a transmitter processor 415, wherein the transmitter / receiver 416 includes an antenna 420.

[0210] In the downlink (DL), upper-layer packets, such as the upper-layer information included in the first information block of this application and the upper-layer information included in the first signaling (when the first signaling includes upper-layer information), are provided to the controller / processor 440. The controller / processor 440 implements L2 and higher-layer functions. In the DL, the controller / processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation for the first node device 450 based on various priority metrics. The controller / processor 440 is also responsible for HARQ operations, retransmission of lost packets, and the generation of signaling to the first node device 450, such as the higher-layer information included in the first information block of this application and the higher-layer information included in the first signaling (when the first signaling includes higher-layer information), in the controller / processor 440. Transmit processor 415 implements various signal processing functions for the L1 layer (i.e., the physical layer), including encoding, interleaving, scrambling, modulation, power control / allocation, precoding, and physical layer control signaling generation. For example, the generation of the first signaling (when the first signaling only includes physical layer information) and the physical layer signal carrying the first information block is completed in transmit processor 415. The generated modulation symbols are divided into parallel streams and each stream is mapped to a corresponding multicarrier subcarrier and / or multicarrier symbol, and then transmitted by transmit processor 415 via transmitter 416 to antenna 420 in the form of radio frequency signals. At the receiving end, each receiver 456 receives the radio frequency signal through its corresponding antenna 460. Each receiver 456 recovers the baseband information modulated onto the radio frequency carrier and provides the baseband information to receiver processor 452. Receiver processor 452 implements various signal reception processing functions for the L1 layer. The signal reception and processing function includes receiving the physical layer signal carrying the first information block and the first signaling in this application; demodulating the multi-carrier symbols in the multi-carrier symbol stream based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)); subsequently descrambling, decoding, and deinterleaving to recover the data or control transmitted by the second node device 410 on the physical channel; and then providing the data and control signals to the controller / processor 490. The controller / processor 490 is responsible for the L2 layer and above, and interprets the higher-layer information included in the first information block and the higher-layer information included in the first signaling (when the first signaling includes upper-layer information). The controller / processor may be associated with a memory 480 that stores program code and data. The memory 480 may be referred to as computer-readable media.

[0211] In uplink (UL) transmission, similar to downlink transmission, higher-layer information, including the higher-layer information carried by the target PUSCH in this application (when carrying higher-layer information), is generated by the controller / processor 490 and then processed by the transmitter processor 455 to perform various signal transmission processing functions for the L1 layer (i.e., physical layer). This includes the generation of the physical layer signal of the target PUSCH in this application, which is completed by the transmitter processor 455 and then transmitted by the transmitter processor 455 via the transmitter 456 to the antenna 460 as a radio frequency signal.
