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 design scheme and apparatus for feedback information transmission in wireless communication.

Background

In a conventional LTE (Long-Term Evolution ) and LTE-a (Long-Term Evolution-enhanced) system, a base station supports a terminal To receive a Multicast service in a Single-Cell-Point-To-Multipoint (SC-PTM) manner through an MBSFN (Multicast Broadcast Single Frequency Network). The NR (New Radio) R (release) -17 standard has begun to discuss how Multicast (Multicast) and Broadcast (Broadcast) services can be supported under a 5G architecture. In the discussion of two PTM transmission schemes, one is a Group Common (Group Common) PDCCH (Physical Downlink Control Channel) scheduling Group Common PDSCH (Physical Downlink Shared Channel), and the other is a User Equipment (UE) dedicated (Specific) PDCCH scheduling Group Common PDSCH.

Disclosure of Invention

Currently, a scheme for PTM (Point-To-Multipoint) transmission is being discussed, and existing SPS (Semi-Persistent Scheduling) transmission is still supported in an MBS (Multicast Broadcast service) scenario. In the 5G NR system, whether transmission of a downlink signaling for activating/releasing an SPS is correctly received or not needs to be fed back by a terminal side through a PUCCH (Physical Uplink Control Channel) or a PUSCH (Physical Uplink Shared Channel), and based on the discussion of the existing PTM transmission manner, a PDCCH dedicated to a user equipment may schedule data transmission of an MBS service, and further, when the SPS transmission under the MBS service is activated or released through the PDCCH of UE-Specific, how to determine a time-frequency resource occupied by the feedback for activating or releasing the MBS service 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 communication scenario of PTM as an example, the present application is also applicable To other scenarios, such as unicast system, and achieves the technical effect similar To that in PTM (Point-To-Multipoint). Furthermore, the adoption of a unified solution for different scenarios (including but not limited to PTM) also helps to reduce hardware complexity and cost. Without conflict, embodiments and features in embodiments in any node of the present application may apply to any other node, and vice versa.

It should be noted that, without conflict, the embodiments and features in the embodiments in the user equipment of the present application may be applied to the base station, and vice versa. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict. Further, although the purpose of the present application is for cellular networks, the present application can also be used for internet of things and car networking. Further, although the present application was originally directed to multi-carrier communication, the present application can also be applied to single-carrier communication. Further, although the present application was originally directed to multicast, it can also be used for unicast communication. Further, although the original intention of the present application is directed to the terminal and base station scenario, the present application is also applicable to the terminal and terminal, the terminal and relay, the Non-Terrestrial network (NTN), 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 the communication scenario of the terminal and the base station) also helps to reduce hardware complexity and cost.

As an embodiment, one technical feature of the above method is that: when unicast PDCCH (physical downlink control channel), namely the first signaling, is used for activating/releasing multicast transmission, namely the first type of signals, the position of a time domain resource occupied by corresponding feedback information of multicast transmission, namely the time domain position of the time domain resource occupied by the target information block does not refer to the time domain position of the first signaling, but is related to the position of a search space set which is closest to the first signaling and is allocated for scheduling MBS service, namely the position of the time domain resource occupied by the first search space set.

As an embodiment, another technical feature of the above method is: the method not only realizes the activation/release of the multicast service by the unicast PDCCH, but also can be used for other configurations related to the multicast PUCCH, and has better compatibility with the existing system.

As an example, compared with the conventional scheme, the method has the following advantages:

when unicast PDCCH, i.e. the first signaling, is used to activate/release multicast transmission, i.e. the first type of signal, the position of the time domain resource occupied by the feedback information of the corresponding multicast transmission, i.e. the time domain position of the time domain resource occupied by the target information block, does not refer to the time domain position of the first signaling, but is related to the position of the closest search space set allocated for scheduling MBS services to the first signaling, i.e. the position of the time domain resource occupied by the first search space set; besides realizing the activation/release of multicast service by adopting a unicast PDCCH, the method can be used for other configurations related to the multicast PUCCH, and has better compatibility with the existing system;

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 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 multiple antenna transmit processor 457, a multiple 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 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 a controller/processor 475. The controller/processor 475 implements the functionality of the L2 layer. 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 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 received analog precoded/beamformed baseband multicarrier symbol stream 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 communication 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 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 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. The 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 communication 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 that is provided 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. 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 transmission from the first communication device 450 to the second communication 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.
