Description

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 related to multiple antennas 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) is decided to be researched in 3GPP (3 rd Generation Partner Project, third Generation partnership project) RAN (RadioAccess Network ) #72 full-time, and a standardization Work for NR is started in 3GPP RAN #75 full-time with NR's WI (Work Item).

One key technology of NR is to support beam-based signal transmission, and its main application scenario is to enhance coverage of NR devices operating in the millimeter wave band (e.g., a band greater than 6 GHz). In addition, beam-based transmission techniques are also required to support large-scale antennas in low frequency bands (e.g., frequency bands less than 6 GHz). By weighting the antenna array, the rf signal forms a stronger beam in a particular spatial direction, while the 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 with each other, so that signals are sent and received with stronger power, and the coverage performance is improved. Beam measurement and feedback of an NR system operating in the millimeter wave band may be accomplished through a plurality of synchronous broadcast signal blocks (sspbch blocks, SSBs) and channel state Information reference signals (CHANNEL STATE Information-REFERENCE SIGNAL, CSI-RS). Different SSBs or CSI-RS may be transmitted by using different beams, and the User Equipment (UE) measures SSBs or CSI-RS sent by the gNB (next generation node B ) and feeds back SSB indexes or CSI-RS resource numbers to complete beam alignment.

In conventional cellular systems, data transmission can only occur over licensed spectrum, however with a dramatic increase in traffic, especially in some urban areas, licensed spectrum may be difficult to meet the traffic demand. 3GPP Release 17 will consider extending the application of NR to unlicensed spectrum above 52.6 GHz. To ensure compatibility with other access technologies on unlicensed spectrum, LBT (Listen Before Talk, listen-before-talk) technology is used to avoid interference due to multiple transmitters simultaneously occupying the same frequency resources. For unlicensed spectrum above 52.6GHz, directional LBT (Directional LBT) techniques are more suitable to avoid interference because beam-based signal transmissions have significant directivity.

In the Cat 4LBT (fourth type of LBT, category 4LBT, see 3gpp tr 36.889) procedure of LTE and NR, a transmitter (base station or user equipment) first performs energy detection during a delay period (refer Duration), and if the detection result is that a channel is idle, back off (backoff) is performed and energy detection is performed during the back off time. The time of backoff is counted in CCA (CLEAR CHANNEL ASSESSMENT ) slot periods, the number of slot periods of backoff being randomly selected by the transmitter within the CWS (Contention Window Size ). Thus, the duration of Cat 4LBT is uncertain. Cat 2LBT (second type of LBT, category 2LBT, see 3GPP TR36.889) is another type of LBT. Cat 2LBT determines whether a channel is idle by evaluating the energy level for a specific period of time. The duration of Cat 2LBT is determined. A similar mechanism is employed in NR. Cat 4LBT is used in downlink, also called Type 1downlink channel Access procedure (Type 1downlink channel access procedures); cat 4LBT is used in uplink, also called Type 1uplink channel Access procedure (Type 1uplink channel access procedures); cat 2LBT is used in the downstream and is also called Type 2downlink channel access procedure (Type 2downlink channel access procedures) Cat 2LBT is used in the upstream and is also called Type 2uplink channel access procedure (Type 2uplink channel access procedures). Specific definition can refer to 3gpp ts37.213, and Cat 4LBT in the present application is also used to represent a type 1downlink channel access procedure or a type 1uplink channel access procedure, and Cat 2LBT in the present application is also used to represent 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 LBT in that direction passes. Furthermore, for the millimeter wave band, shielding of an object or a human body may also cause a wireless signal in a certain direction to be not properly transmitted. If the directional LBT cannot pass or the occlusion is present for a long period of time, the wireless signal may fail in the wireless link due to an inability to transmit smoothly.

Disclosure of Invention

The inventor finds that the directional LBT technology is beneficial to improving the spectrum multiplexing efficiency and transmission performance of an NR system working on an unlicensed spectrum. Unlike an omni-directional LBT, a directional LBT is successful and then only signal transmission in the beam direction in which the LBT is successful, while signal transmission in the direction in which the directional LBT is not performed or in the direction in which the directional LBT is not successful will be limited. Therefore, how to avoid radio link failure due to an excessive number of LBT failures in a specific direction or long-time blocking of signals 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 on the unlicensed spectrum as an example, the present application is also applicable to other communication scenarios (such as a wlan scenario, a sidelink transmission scenario between the UE and the UE, etc.), and is also applicable to licensed spectrum, and achieves similar technical effects. Furthermore, the use of unified solutions for different scenarios (including but not limited to cellular networks, wireless local area networks, sidelink transmissions, licensed spectrum and unlicensed spectrum, etc.) 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 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.
