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 information with different 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] This application discloses a solution to the problem of UCI multiplexing associated with different priority levels. It should be noted that URLLC is only used as a typical application scenario or example in the description of this application; this application is also applicable to other scenarios facing similar problems (such as scenarios with multiple services coexisting, or other scenarios with multiplexing of information with different priority levels, or scenarios with multiplexing of services with different QoS requirements, or 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) also 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 signaling message, the first signaling message being used to determine a first time-frequency resource set, the first time-frequency resource set including multiple REs;

[0008] A target bit subset is determined and a first signal is transmitted in the first time-frequency resource set. The target bit subset includes multiple bits, and any bit included in the target bit subset belongs to a first bit sequence. The first bit sequence is used to generate the first signal. The first bit sequence includes multiple sequentially indexed bits.

[0009] Wherein, the target quantity is equal to the number of bits included in the target bit subset, and the first signaling is used to determine the target quantity; the first time-frequency resource set includes a candidate RE set, and the target symbol is a symbol other than the latest symbol occupied by the candidate RE set in the time domain; the first intermediate quantity is equal to the number of bits carried by the candidate RE set after the target symbol, and the first feature quantity is equal to the number of REs included in the candidate RE set occupying the target symbol in the time domain. The target quantity, the first intermediate quantity, and the first feature quantity are used together to determine the target interval, and the target interval is a positive integer. The target interval is used to determine the distribution of the target bit subset in the first bit sequence.

[0010] As an example, the distribution of the target bit subset in the first bit sequence is determined according to the target interval, thereby supporting the determination of the RE resources occupied by the low priority UCI from back to front, ensuring the delay performance of the high priority UCI and UL-SCH when reusing the low priority UCI, and avoiding or reducing the adverse effects on the high priority transmission.

[0011] As an example, having the target symbol earlier than the latest symbol ensures that the discrete REs occupied by low-priority UCIs in the frequency domain are distributed first, thereby avoiding high-priority UCIs from being mapped into later REs and further avoiding the impact on the latency of high-priority transmissions.

[0012] According to one aspect of this application, the method is characterized in that the first signaling is used to determine a first level index value, and the second level index value is equal to the priority index value of the bits included in the target bit subset; the first level index value is a non-negative integer, the second level index value is a non-negative integer, and the second level index value is not equal to the first level index value.

[0013] According to one aspect of this application, the method is characterized in that the bits included in the target bit subset are indexed sequentially, the feature bit is a bit included in the target bit subset, the index value of the feature bit in the first bit sequence is equal to the first sequential index value, and the index value of the feature bit in the target bit subset is equal to the second sequential index value; the first sequential index value and the second sequential index value are positively correlated.

[0014] As an example, while supporting backward determination of the REs occupied by low-level UCIs in the time domain, the forward-to-back resource mapping in the time domain is still maintained, reducing the impact on the standard while supporting advance decoding of low-level UCIs.

[0015] According to one aspect of this application, the method is characterized in that the first bit sequence includes a first HARQ subset and a first data subset, the first HARQ subset including at least one bit, and the first data subset including at least one bit; the priority index value of the first HARQ subset and the priority index value of the first data subset are both greater than the priority index value of the target bit subset; the target bit subset is multiplexed into the first bit sequence before the first data subset, and the number of HARQ-ACK bits generated for the first HARQ subset is used to determine the order in which the first HARQ subset is multiplexed into the first bit sequence.

[0016] As an example, by arranging UCIs of different priorities and the multiplexing order of data bits, it is possible to support the multiplexing of low-priority UCIs onto symbols with later time domains without affecting the existing multiplexing design, thereby reducing the impact of the standard and maintaining backward compatibility.

[0017] According to one aspect of this application, the method is characterized in that the first signaling is used to determine a first offset value, the first offset value being one of X1 candidate offset values, where X1 is a positive integer greater than 1, and one of the X1 candidate offset values ​​is less than 1; a first type of bit subset is used to generate the target bit subset, the first type of bit subset including at least one control information bit, and the first offset value, the number of control information bits included in the first type of bit subset, and the number of REs included in the first time-frequency resource set are used together to determine the target quantity.

[0018] According to one aspect of this application, the method is characterized in that the number of REs included in the candidate RE set is equal to the reference number; when the number of control information bits included in the first type of bit subset is not greater than a first threshold, the first offset value, the first threshold, and the number of REs included in the first time-frequency resource set are used together to determine the reference number, wherein the first threshold is a positive integer; the candidate RE set includes any RE in the first time-frequency resource set whose time-domain symbol is later than the target symbol and can be used in the first type of bit subset, the number of REs included in the first time-frequency resource set whose time-domain symbol is occupied by the target symbol and can be used in the first type of bit subset is equal to the second feature number, and the first feature number and the second feature number are used together to determine the frequency domain distribution of the REs included in the candidate RE set whose time-domain symbol is occupied by the target symbol.

[0019] According to one aspect of this application, the method is characterized in that the first signal is used to carry a second type of bit subset, the second type of bit subset including at least one information bit, the second type of bit subset is used to generate a second bit sequence, the second bit sequence including at least one bit; the type of information bits included in the second type of bit subset, the number of control information bits included in the first type of bit subset, and the first offset value are used together to determine whether the first bit sequence includes all the bits of the second bit sequence.

[0020] As an example, when determining the UCI multiplexing method (perforation or rate matching), the influence of the first offset value is considered, thereby achieving a balance between the performance impact and resource consumption caused by HARQ-ACK missed detections, and minimizing the adverse effects on high-priority UCI or high-priority data transmission caused by multiplexing low-priority HARQ-ACK.

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. NG-RAN includes NR / Evolved Node B (gNB / eNB) 203 and other gNBs (eNBs) 204. gNBs (eNBs) 203 provide user and control plane protocol termination to UE 201. gNBs (eNBs) 203 can connect to other gNBs (eNBs) 204 via Xn / X2 interfaces (e.g., backhaul). gNBs (eNBs) 203 may also be referred to as a base station, base transceiver station, radio base station, radio transceiver, transceiver function, Basic Services Set (BSS), Extended Services Set (ESS), TRP (Transmitter Receiver Node), or some other suitable terminology. gNBs (eNBs) 203 provide UE 201 with an access point to the 5GC / EPC 210.

[0229] Example 3

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 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.).

[0238] 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.

[0239] In the DL (Downlink), upper-layer packets are provided to controller / processor 440. Controller / processor 440 implements functions of L2 layer and above. In the DL, controller / processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to first node device 450 based on various priority metrics. Controller / processor 440 is also responsible for HARQ operation, retransmission of lost packets, and higher-layer signaling to first node device 450. Transmit processor 415 implements various signal processing functions for L1 layer (i.e., physical layer), including coding, interleaving, scrambling, modulation, power control / allocation, precoding, and physical layer control signaling generation, such as the generation of the first signaling in this application, which is completed in transmit processor 415. The generated modulation symbols are divided into parallel streams and each stream is mapped to corresponding multicarrier subcarriers and / or multicarrier symbols, which are then mapped by transmit processor 415 to antenna 420 via transmitter 416 and transmitted as radio frequency signals. At the receiving end, each receiver 456 receives radio frequency signals through its corresponding antenna 460, recovers the baseband information modulated onto the radio frequency carrier, and provides the baseband information to the receiver processor 452. The receiver processor 452 implements various signal reception processing functions of the L1 layer. The signal reception processing functions include receiving 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)), followed by 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-level 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.

[0240] In uplink (UL) transmission, similar to downlink transmission, higher-layer information, including the higher-layer information carried by the first signal in this application, 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). The physical layer signal of the first signal is mapped by the transmitter processor 455 to the antenna 460 via the transmitter 456 and transmitted as a radio frequency signal. The receiver 416 receives the radio frequency signal through its corresponding antenna 420. Each receiver 416 recovers the baseband information modulated onto the radio frequency carrier and provides the baseband information to the receiver processor 412. The receiver processor 412 performs various signal reception processing functions for the L1 layer (i.e., physical layer), including receiving and processing the physical layer signal carrying the first signal in this application, and then providing data and / or control signals to the controller / processor 440. The controller / processor 440 performs L2 layer functions, including interpreting higher-layer information, such as the higher-layer information carried by the second signal in this application (when the second signal carries higher-layer information). The controller / processor may be associated with a buffer 430 that stores program code and data. The buffer 430 can be computer-readable media.
