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 an Unlicensed Spectrum (Unlicensed Spectrum) related transmission scheme and apparatus 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 air interface technology (NR, New Radio) (or fine generation, 5G) is decided on 3GPP (3rd generation Partner Project) RAN (Radio Access Network) #72 sessions, and Work on NR starts on 3GPP RAN #75 sessions where WI (Work Item) of NR passes.
One key technology of NR is to support beam-based signal transmission, and its main application scenario is to enhance the coverage performance 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. Meanwhile, with the development of terminal devices, when a terminal is configured with a plurality of panels (panels), the terminal can simultaneously perform reception or transmission in a plurality of beam directions. In addition, in NR, the number of blind detection times based on one kind of SCS (sub-carrier Spacing) and the number of independent CCEs (Control Channel Elements) in one slot (slot) in one BWP (Bandwidth Part) of the terminal have upper limits; and the terminal can perform blind detection dynamic Sharing (Sharing) between a plurality of CORESETs (Control Resource sets) and a Search Space Set (Search Space Set) to improve the scheduling possibility. When the terminal performs wireless communication on the unlicensed spectrum, whether a beam can be used by the base station for communication is also limited by whether channel sensing passes, and the above scenario will make blind detection at the terminal side more complicated, and further needs to be redesigned.
Disclosure of Invention
In a large-scale antenna combining unlicensed spectrum scene based on beam transmission, because of the increase of beams, a terminal needs to blindly detect a PDCCH (physical downlink Control Channel) in a search space set corresponding to a plurality of beams. Currently, in NR, PDCCH candidates (candidates) in a search space set are all configured semi-statically through higher layer signaling. When the result of the base station LBT (Li sten-before talk, session after monitoring) is uncertain, the PDCCH candidate on the actually configured search space set does not need to be blind-detected, and the blind detection capability under reservation will be wasted.
In view of the above application scenarios and requirements, the present application discloses a solution, and it should be noted that, in a non-conflicting situation, features in the embodiments and embodiments of the first node in the present application may be applied to a base station, and features in the embodiments and embodiments of the second node in the present application may be applied to a terminal. In the meantime, the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict.
Further, although the original purpose of the present application is to the scenario of unlicensed spectrum, the present application can also be used in the scenario of licensed spectrum. Further, although the purpose of the present application is to target at a multi-beam scene under a large-scale antenna, the present application is also applicable to a scene of a non-large-scale antenna, and a technical effect similar to that under the large-scale antenna is obtained. Furthermore, the adoption of a unified solution for different scenarios (including but not limited to the communication scenario of the terminal and the base station) also helps to reduce hardware complexity and cost.

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 450 and a second communication device 410 communicating with each other in an access network.
The first 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.
The second communication 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.
In the transmission from the second communication device 410 to the first communication device 450, at the second 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 second 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 first communications device 450 based on various priority metrics. The controller/processor 475 is also responsible for retransmission of lost packets, and signaling to the first 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 410, as well as 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 second communications apparatus 410 to the first communications apparatus 450, each receiver 454 receives a signal through its respective antenna 452 at the first communications apparatus 450. 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 first 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 second 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 second 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 first communications device 450 to the second communications device 410, a data source 467 is used at the first 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 send function at the second communications apparatus 410 described in the transmission from the second communications apparatus 410 to the first 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 second 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 first communication device 450 to the second communication device 410, the functionality at the second communication device 410 is similar to the receiving functionality at the first communication device 450 described in the transmission from the second communication device 410 to the first 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 transmission from the first communications device 450 to the second 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. Upper layer data packets from the controller/processor 475 may be provided to a core network.
