-the name of the invention of the original application: method and apparatus in a node for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission scheme and apparatus for random access in wireless communication.

Background

Future wireless communication systems have more and more diversified application scenes, and different application scenes have different performance requirements on the system. To meet the different performance requirements of various application scenarios, a New air interface technology (NR) study is decided on the 3GPP (3 rd Generation Partner Project, third Generation partnership project) RAN (Radio Access Network ) #72 full-time, and a standardization Work for NR is started on the 3GPP RAN #75 full-time with the WI (Work Item) of NR.

In order to be able to adapt to various application scenarios and meet different requirements, a research project of Non-orthogonal multiple access (NoMA, non-orthogonal Multiple Access) under NR is also passed on the 3gpp ran#76 meeting, and starts with Release 16 version, and starts with WI after SI ends to standardize the related technology. As a study item for accepting NoMA, WI of two-step random access (2-step RACH) under NR was also passed on the 3gpp ran #82 full-scale.

Disclosure of Invention

The NR Release-16 system introduces a two-Step random access procedure (2-Step RACH, random Access Channel) to meet the fast access requirements. The MsgA (Message a) of the two-step random access procedure includes a random access preamble (PRACH preamble) and a physical uplink shared channel load (PUSCH payload); wherein, the random access preamble is sent on one RO (RACH timing), and the physical uplink shared channel load occupies one PRU (PUSCH Resource Unit, shared channel resource unit) to be sent on one PO (PUSCH timing). The random access preamble and the PRU in message a are each independently configured and part of the random access preamble and part of the PRU are invalid due to some resource collision. The association mapping between the random access preamble and the PRU in message a is implicitly determined, resulting in a partial random access preamble without a corresponding PRU association. When a User Equipment (UE) selects a random access preamble that always selects no associated PRU, the PUSCH load cannot be transmitted in message a, resulting in this UE actually operating in a four-step random access procedure. The RAR response window for the two-step random access procedure is typically longer than the RAR response window for the four-step random access procedure. When the UE is configured as a two-step random access procedure and selects a preamble without an associated PRU, the access delay of the two-step random access procedure is longer than that of the four-step random access rate procedure, and the normal access delay requirement cannot be guaranteed.

In view of the above problems, the present application discloses an RAR response mechanism in a random access procedure, which can ensure that when a UE selects a random access preamble without an associated PRU, the performance of access delay is equivalent to that of a four-step access procedure. It should be noted that, without conflict, the embodiments in the user equipment and the features in the embodiments of the present application may be applied to the base station, and vice versa. The embodiments of the present application and features in the embodiments may be combined with each other arbitrarily without conflict. Further, while the present application is initially directed to random access, the present application can also be used for beam failure recovery (Beam Failure Recovery).

Further, while the present application is primarily directed to Uplink (Uplink), the present application can also be used with Sidelink (sidlink). Further, while the present application is primarily directed to single carrier communications, the present application can also be used for multi-carrier communications. Further, while the present application is primarily directed to single antenna communications, the present application can also be used for multiple antenna communications. Further, although the present application is initially directed to the terminal and base station scenario, the present application is also applicable to the V2X scenario, the terminal and relay, and the communication scenario between the relay and the base station, and similar technical effects in the terminal and base station scenario are obtained. Furthermore, the adoption of a unified solution for different scenarios (including but not limited to V2X scenarios and communication scenarios of terminals with base stations) also helps to reduce hardware complexity and cost.

It should be noted that the term (terminal) in the present application is explained with reference to the definitions in the specification protocols TS36 series, TS37 series and TS38 series of 3GPP, but can also refer to the definitions of the specification protocols of IEEE (Institute of Electrical and Electronics Engineers ).

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.

Example 4

Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in fig. 4. Fig. 4 is a block diagram of a first communication device 410 and a second communication device 450 in communication with each other in an access network.

The first communication device 410 includes a controller/processor 475, a memory 476, 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.

The second 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.

In the transmission from the first communication device 410 to the second communication device 450, upper layer data packets from the core network are provided to a controller/processor 475 at the first communication device 410. The controller/processor 475 implements the functionality of the L2 layer. In the transmission from the first communication device 410 to the first communication device 450, a controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication device 450 based on various priority metrics. The controller/processor 475 is also responsible for retransmission of lost packets and signaling to the second 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., physical layer). Transmit processor 416 performs coding and interleaving to facilitate Forward Error Correction (FEC) at the second communication device 450, as well as mapping of signal clusters 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 digitally space-precodes the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. A transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes with reference signals (e.g., pilots) in the time and/or frequency domain, and then uses an Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying the time domain multicarrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding/beamforming operations on the time domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multiple antenna transmit processor 471 to a radio frequency stream and then provides it to a different antenna 420.

In a transmission from the first communication device 410 to the second communication device 450, each receiver 454 receives a signal at the second communication device 450 through its respective antenna 452. Each receiver 454 recovers information modulated onto a radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream that is provided to a receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various signal processing functions for the L1 layer. A multi-antenna receive processor 458 performs receive analog precoding/beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. The receive processor 456 converts the baseband multicarrier symbol stream after receiving the analog precoding/beamforming operation from the time domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receive processor 456, wherein the reference signal is to be used for channel estimation, and the data signal is subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial stream destined for the second communication device 450. The symbols on each spatial stream are demodulated and recovered in a receive processor 456 and soft decisions are generated. A receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals that were transmitted by the first communication device 410 on the physical channel. The upper layer data and control signals are then provided to the controller/processor 459. The controller/processor 459 implements the functions of the L2 layer. The controller/processor 459 may be associated with a memory 460 that stores program codes and data. Memory 460 may be referred to as a computer-readable medium. In the transmission from the first communication device 410 to the second 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. The upper layer packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

In the transmission from the second communication device 450 to the first communication device 410, a data source 467 is used at the second communication device 450 to provide upper layer data packets to a controller/processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the transmit functions at the first communication device 410 described in the transmission from the first communication device 410 to the second 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 allocations, implementing L2 layer functions for the user and control planes. The controller/processor 459 is also responsible for retransmission of lost packets and signaling to the first communication device 410. The transmit processor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming, with the multi-antenna transmit processor 457 performing digital multi-antenna spatial precoding, after which the transmit processor 468 modulates the resulting spatial stream into a multi-carrier/single-carrier symbol stream, which is analog precoded/beamformed in the multi-antenna transmit processor 457 before being provided to the 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 provides it to an antenna 452.

In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving function at the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals to baseband signals, and provides the baseband signals to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 collectively implement the functions of the L1 layer. The controller/processor 475 implements L2 layer functions. The controller/processor 475 may be associated with a memory 476 that stores program codes and data. Memory 476 may be referred to as a computer-readable medium. In the transmission from the second communication device 450 to the first communication device 410, a controller/processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the UE 450. Upper layer packets from the controller/processor 475 may be provided to the core network.
