Method and device used in wireless communication node

Technical Field

Background

In the future, the application scenes of the wireless communication system are more and more diversified, and different application scenes put different performance requirements on the system. In order to meet different performance requirements of various application scenarios, a New air interface technology (NR, new Radio) (or 5G) is determined to be studied in 3GPP (3 rd Generation Partner Project) RAN (Radio Access Network) #72 fairs, and standardization Work on NR starts after passing through WI (Work Item) of the New air interface technology (NR, new Radio) in 3GPP RAN #75 fairs. The decision to start the Work of SI (Study Item) and WI (Work Item) of NR Rel-17 was decided on the 3GPP RAN # 86-time congress.

Among new air interface technologies, enhanced Mobile BroadBand (eMBB), ultra-reliable and Low Latency Communications (URLLC), and mass Machine Type Communications (mtc) are three main application scenarios.

Disclosure of Invention

In NR Rel-16, when UCI (Uplink Control Information) having different priority levels collide in the time domain, UCI of low priority level is discarded to guarantee transmission of UCI of high priority level. In NR Rel-17, multiplexing of UCI of different priority levels is supported on the same PUCCH or the same PUSCH.

The present application discloses a solution to the multiplexing problem of UCI associated to different priority levels. It should be noted that, in the description of the present application, URLLC is only used as a typical application scenario or example; the application is also applicable to other scenarios (for example, scenarios where multiple services coexist, or other scenarios where information with different priority levels is multiplexed, or scenarios where services with different QoS requirements are multiplexed, or for different application scenarios, such as car networking and eMBB multiplexing, etc.), which face similar problems, and can also achieve similar technical effects. Furthermore, the adoption of a unified solution for different scenarios (including but not limited to scenarios of URLLC) also helps to reduce hardware complexity and cost.

Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for a link between the first node device and the second node device through PHY301. The L2 layer 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, which terminate at the second node device.

In the DL (Downlink), upper layer packets, such as the upper layer information carried by the first signal in this application (when the first signal includes upper layer information), are provided to the controller/processor 440. The controller/processor 440 performs the functions of the L2 layer and above. In the DL, a controller/processor 440 provides packet header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to a first node device 450 based on various priority metrics. Controller/processor 440 is also responsible for HARQ operations, retransmission of lost packets, and signaling to first node device 450, such as higher layer information included in the first signal in this application, generated in controller/processor 440. The transmit processor 415 implements various signal processing functions for the L1 layer (i.e., physical layer), including encoding, interleaving, scrambling, modulation, power control/allocation, precoding, and physical layer control signaling generation, such as first signaling and second signaling and generation of a physical layer signal carrying the first signal as described herein, performed at the transmit processor 415. The generated modulation symbols are divided into parallel streams and each stream is mapped to a corresponding multi-carrier subcarrier and/or multi-carrier symbol and then transmitted as radio frequency signals by a transmit processor 415 via a transmitter 416 to an antenna 420. On the receive side, each receiver 456 receives a radio frequency signal through its respective antenna 460, and each receiver 456 recovers baseband information modulated onto a radio frequency carrier and provides the baseband information to a receive processor 452. The receive processor 452 implements various signal receive processing functions of the L1 layer. The signal reception processing functions include reception of the physical layer signal carrying the first signal and the first signaling and the second signaling in this application, demodulation based on various modulation schemes (e.g., binary Phase Shift Keying (BPSK), quadrature Phase Shift Keying (QPSK)) over multicarrier symbols in a multicarrier symbol stream, followed by descrambling, decoding, and deinterleaving to recover data or control transmitted by the second node device 410 over the physical channel, followed by providing the data and control signals to the controller/processor 490. The controller/processor 490 is responsible for the L2 layer and above, and the controller/processor 490 interprets the higher layer information (when the first signal includes upper layer information) included in the first signal in the present application. The controller/processor can be associated with a memory 480 that stores program codes and data. Memory 480 may be referred to as a computer-readable medium.

In Uplink (UL) transmission, similar to downlink transmission, the high layer information including the high layer information carried by the first PUSCH in the present application is generated by the controller/processor 490, and then is subjected to various signal transmission processing functions for the L1 layer (i.e., physical layer) by the transmission processor 455, wherein the determination of the first PUCCH and the determination of the second signal are generated by the transmission processor 455, and then the physical layer signal of the second signal is mapped to the antenna 460 by the transmission processor 455 via the transmitter 456 and is transmitted in the form of a radio frequency signal. Receivers 416 receive radio frequency signals through their respective antennas 420, each receiver 416 recovers baseband information modulated onto a radio frequency carrier, and provides the baseband information to receive processor 412. The receive processor 412 performs various signal receive processing functions for the L1 layer (i.e., physical layer), including receive processing of physical layer signals carrying the second signal in this application, and then provides data and/or control signals to the controller/processor 440. Implementing the L2 layer functions at controller/processor 440 includes interpreting higher layer information, such as that carried by the second signal in this application (when the second signal carries higher layer information). The controller/processor can be associated with a buffer 430 that stores program codes and data. Buffer 430 may be a computer-readable medium.
