Description
Technical Field
The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission method and apparatus for wireless signals in a wireless communication system supporting a cellular network.
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 the 3GPP (3 rd GenerationPartnerProject, third Generation partnership project) RAN (Radio Access Network ) #72 times of the whole meeting, and standardized Work is started on NR by the 3GPP RAN #75 times of the whole meeting through the WI (Work Item) of NR.
The multi-antenna technology is a key technology in a 3GPP (3 rd Generation Partner Project, third generation partnership project) LTE (Long-term evolution) system and an NR (new radio) system. Additional spatial freedom is obtained by configuring multiple antennas at a communication node, such as a base station or UE (User Equipment). The multiple antennas are formed by beam forming, and the formed beams point to a specific direction to improve the communication quality. When a plurality of antennas belong to a plurality of TRP (Transmission/reception point)/panel (antenna panel), an additional diversity gain can be obtained by using a spatial difference between different TRP/panels. The beams formed by multi-antenna beamforming are generally relatively narrow, and the beams of both communicating parties need to be aligned for effective communication. When there is a mismatch between the transmit/receive beams due to UE movement or the like, the communication quality will be greatly degraded or even impossible to communicate, and thus the beams need to be updated in time. In the NR protocol, TCI (Transmission Configuration Indicator, transmission configuration indication) is used to determine a Quasi co-location (QCL) relationship of a physical channel, and the Quasi co-location relationship is used to determine a large-scale fading characteristic and a reception beam of the physical channel. For PDSCH (PhysicalDownlink SharedChannel ), the gNB (next generationNode B, next generation node B) first configures multiple TCI states for the UE through RRC (Radio Resource Control) layer signaling and MAC-CE (MediumAccess Control-Control Element), and then indicates one of the multiple TCI states to the UE through PDCCH (Physical Downlink Control Channel ), and the UE uses the TCI states to determine the quasi co-sited relationship and reception beam of the PDSCH.
Disclosure of Invention
WI (Work Item) of NRR (release) 17 is passed through 3gpp ran (RadioAccess Network ) #86 full-meeting, including enhanced multi-TRP transmission to support HST (High Speed Train) -SFN (Single FrequencyNetwork ) scenarios. The inventor finds through research that in the HST-SFN scenario, the main challenges encountered by signal transmission include the effect of doppler shift on receiver performance due to high-speed mobility. Also, since the directions of the different TRPs with respect to the UE are different, doppler shifts generated at the UE receiver by signals transmitted from the different TRPs are different, and the UE receiver will receive a plurality of copies of signals having different center frequencies, which makes reception of signals difficult.
In view of the above, the present application discloses a solution. It should be noted that, although the above description uses beamforming and HST-SFN scenarios as examples, the present application is also applicable to other scenarios such as LTE multi-antenna systems, medium-low speed mobile scenarios, and achieves technical effects similar to those in beamforming and HST-SFN scenarios. Furthermore, the adoption of a unified solution for different scenarios (including but not limited to beamforming, HST-SFN scenarios, LTE multi-antenna systems and medium and low speed mobile scenarios) also helps to reduce hardware complexity and cost.

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.

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.
