Description

Method and apparatus in a node used 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 related to multiple antennas in wireless communication.

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, research on New Radio interface (NR) technology (or fine Generation, 5G) is decided in 3GPP (3rd Generation Partner Project) RAN (Radio access Network) #72 fairs, and standardization Work on NR is started in 3GPP RAN #75 fairs that passed NR.

One key technology for NR is to support beam-based signal transmission, and its main application scenario is to enhance the coverage of NR devices operating in the millimeter wave frequency band (e.g., greater than 6 GHz). In addition, beam-based transmission techniques are also required to support large-scale antennas at low frequency bands (e.g., less than 6 GHz). Through the weighting process of the antenna array, the rf signal forms a stronger beam in a specific spatial direction, and the rf signal is weaker in other directions. After the operations of beam measurement, beam feedback and the like, the beams of the transmitter and the receiver can be accurately aligned to each other, so that signals are transmitted and received with stronger power, and the coverage performance is improved. The beam measurement and feedback of the NR system operating in the millimeter wave band may be accomplished by a plurality of synchronous broadcast Signal blocks (SS/PBCH blocks, SSBs) and Channel State Information-Reference signals (CSI-RS). Different SSBs or CSI-RSs may use different beams for transmission, and a User Equipment (UE) measures an SSB or CSI-RS sent by a gNB (next generation Node B) and feeds back an SSB index or a CSI-RS resource number to complete beam alignment.

In conventional cellular systems, data transmission can only take place over licensed spectrum, however, with the dramatic increase in traffic, especially in some urban areas, licensed spectrum may be difficult to meet traffic demands. 3GPP Release 17 will consider extending the application of NR to unlicensed spectrum above 52.6 GHz. To ensure compatibility with other access technologies over unlicensed spectrum, LBT (Listen Before Talk) techniques are used to avoid interference due to multiple transmitters occupying the same frequency resources at the same time. For unlicensed spectrum above 52.6GHz, directional lbt (directional lbt) techniques are preferably used to avoid interference due to the significant directivity of beam-based signal transmission.

In the Cat4LBT (fourth type LBT, Category 4LBT, see 3GPP TR36.889) procedure of LTE and NR, a transmitter (base station or user equipment) first performs energy detection for a delay period (Defer Duration), and if the detection result is that the channel is idle, performs backoff (backoff) and performs energy detection within the backoff time. The backoff time is counted in CCA (Clear Channel Assessment) time slot periods, and the number of backoff time slot periods is obtained by the transmitter randomly selecting in a CWS (Contention Window Size). Thus, the duration of Cat4LBT is uncertain. Cat2LBT (second type of LBT, Category 2LBT, see 3GPP TR36.889) is another type of LBT. The Cat2LBT determines whether the channel is idle by evaluating the energy level in a specific time period. The duration of Cat2LBT is determined. A similar mechanism is employed in NR. When the Cat4LBT is used for downlink, it is also called Type 1downlink channel access procedure (Type 1downlink channel access procedure); when the Cat4LBT is used for uplink, it is also called Type 1uplink channel access procedure (Type 1uplink channel access procedure); when the Cat2LBT is used for downlink, it is also called Type 2downlink channel access procedure (Type 2downlink channel access procedure) and when the Cat2LBT is used for uplink, it is also called Type 2uplink channel access procedure (Type 2uplink channel access procedure). The specific definition may refer to 3gpp TS37.213, Cat4LBT in this application is also used to indicate a type 1downlink channel access procedure or a type 1uplink channel access procedure, and Cat2LBT in this application is also used to indicate a type 2downlink channel access procedure or a type 2uplink channel access procedure.

For directional LBT, a wireless signal in a certain direction can be transmitted only when the LBT in that direction passes. In addition, for the millimeter wave frequency band, the shielding of an object or a human body may also cause that the wireless signal in a certain direction cannot be correctly transmitted. If the directional LBT fails to pass or the occlusion persists for a longer period of time, the wireless signal may fail due to the inability to transmit successfully.

Disclosure of Invention

The inventors have found through research that the directional LBT technique is beneficial to improve the spectrum multiplexing efficiency and transmission performance of NR systems operating on unlicensed spectrum. Unlike omni-directional LBT, directional LBT can only be successfully followed by signal transmission in the beam direction where LBT was successful, while signal transmission in the direction where directional LBT was not performed or in the direction where directional LBT was not successful will be limited. Therefore, how to avoid the radio link failure caused by the excessive LBT failure times in a specific direction or the signal being blocked for a long time is a problem to be solved.

In view of the above, the present application discloses a solution. It should be noted that, although the above description uses the scenario of air interface transmission between the cellular network gNB and the UE over the unlicensed spectrum as an example, the present application is also applicable to other communication scenarios (for example, a wireless local area network scenario, a sidelink transmission scenario between the UE and the UE, etc.), and is also applicable to the licensed spectrum, and similar technical effects are achieved. Furthermore, the adoption of a unified solution in different scenarios (including but not limited to cellular networks, wireless local area networks, sidelink transmissions, licensed spectrum and unlicensed spectrum) also helps to reduce hardware complexity and cost.

receiving a first signaling and a second signaling;

transmitting a first wireless signal with a first multi-antenna related parameter on a first set of time frequency resources, the first wireless signal comprising a first data block and a second data block;

wherein the first signaling indicates that Q1 multiple antenna related parameters are configured for the first group of time-frequency resources, the Q1 being an integer greater than 1; the second signaling is used for determining a modulation coding mode of the first data block; the first multiple-antenna related parameter is one of the Q1 multiple-antenna related parameters; the first multi-antenna related parameter is used for determining a modulation and coding mode of the second data block; the first data block indicates a modulation coding scheme of the second data block.

As an example, the benefits of the above method include: the first multi-antenna related parameter is self-selected by the first node, and the modulation and coding scheme of the second data block is determined by the first multi-antenna related parameter, so that the modulation and coding scheme of the second data block is unknown to the receiver of the first wireless signal. The modulation and coding mode of the second data block is indicated through the first data block.

The receiver of the first wireless signal can be prevented from performing blind detection on the second data block, which is beneficial to reducing complexity.

As an example, the benefits of the above method include: for the unlicensed spectrum, when the channel occupation time of the first wireless signal may be shared by the receiver of the first wireless signal, the receiver of the first wireless signal may determine the first multi-antenna related parameter according to the first data block, and further determine a spatial direction that may be shared.

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 communicating with each other in an access network.

The first communications device 410 includes a controller/processor 475, a memory 476, a receive processor 470, a transmit processor 416, a multiple antenna receive processor 472, a multiple antenna transmit processor 471, a transmitter/receiver 418, and an antenna 420.

The second communications 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, at the first communication device 410, upper layer data packets from the core network are provided to the controller/processor 475. The controller/processor 475 implements the functionality of layer L2. In transmissions from the first communications device 410 to the first communications device 450, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communications 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., the physical layer). The transmit processor 416 implements coding and interleaving to facilitate Forward Error Correction (FEC) at the second communication device 450 and mapping of signal constellation 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, including codebook-based precoding and non-codebook based precoding, and beamforming processing on the coded and modulated symbols to generate one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, 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 the physical channels carrying the time-domain multicarrier symbol streams. 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 multi-antenna transmit processor 471 into a radio frequency stream that is then provided to a different antenna 420.

In a transmission from the first communications device 410 to the second communications device 450, at the second communications device 450, each receiver 454 receives a signal 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 multi-carrier symbol stream that is provided to a receive processor 456. Receive processor 456 and multi-antenna receive processor 458 implement the various signal processing functions of 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. Receive processor 456 converts the baseband multicarrier symbol stream after the receive 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 signals and the reference signals to be used for channel estimation are demultiplexed by the receive processor 456, and the data signals are subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial streams destined for the second communication device 450. The symbols on each spatial stream are demodulated and recovered at a receive processor 456 and soft decisions are generated. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the first communications device 410 on the physical channel. The upper layer data and control signals are then provided to a controller/processor 459. The controller/processor 459 implements the functionality 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 transmissions from the first communications device 410 to the second communications device 450, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer packets from the core network. The upper layer packet is then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

In a transmission from the second communications device 450 to the first communications device 410, a data source 467 is used at the second communications 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 function at the first communications apparatus 410 described in the transmission from the first communications apparatus 410 to the second communications apparatus 450, the controller/processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller/processor 459 is also responsible for retransmission of lost packets and signaling to said first communications device 410. A transmit processor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding by a multi-antenna transmit processor 457 including codebook-based precoding and non-codebook based precoding, and beamforming, and the transmit processor 468 then modulates the resulting spatial streams into multi-carrier/single-carrier symbol streams, which are provided to different antennas 452 via a transmitter 454 after analog precoding/beamforming in the multi-antenna transmit processor 457. 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 the radio frequency symbol stream to the antenna 452.

In a transmission from the second communication device 450 to the first communication device 410, the functionality at the first communication device 410 is similar to the receiving functionality 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 an rf signal through its respective antenna 420, converts the received rf signal to a baseband signal, and provides the baseband signal to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multiple antenna receive processor 472 collectively implement the functionality of the L1 layer. Controller/processor 475 implements the L2 layer functions. The controller/processor 475 can be associated with a memory 476 that stores program codes and data. Memory 476 may be referred to as a computer-readable medium. In transmissions from the second communications device 450 to the first communications device 410, the controller/processor 475 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer packets from the UE 450.
