Description

Method and device used in user equipment and base station for wireless communication

Technical Field

The present application relates to methods and apparatus in a wireless communication system, and more particularly, to methods and apparatus in a wireless communication system supporting multiple antennas.

Background

Large scale (Massive) MIMO has become a research hotspot for next generation mobile communications. In large-scale MIMO, multiple antennas form a narrow beam pointing to a specific direction by beamforming to improve communication quality. The beams formed by multi-antenna beamforming are generally narrow, and the beams of both communication parties need to be aligned for effective communication. In order to ensure that a UE (User Equipment) can receive or transmit data with a correct beam, the base station transmits beam indication information in scheduling signaling. Since a UE side needs a certain time to monitor and decode the scheduling signaling, when the UE needs to receive downlink data by using the beam specified in the scheduling signaling, the base station needs to reserve a sufficient time interval between the scheduling signaling and the downlink data. According to the discussion result of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) 1, when the time interval between the scheduling signaling and the downlink data is smaller than a threshold value, or the scheduling signaling does not include the beam indication information of the downlink data, the UE receives the downlink data by using a predefined or default beam associated on the control channel.

Disclosure of Invention

The inventors found through research that for UEs supporting Carrier Aggregation (Carrier Aggregation) or multiple BWPs (Bandwidth Part), downlink data and corresponding scheduling signaling may come from different carriers/BWPs. In this case, if the antenna ports on the two carriers/BWPs are not QCL (Quasi Co-Located), the UE cannot receive data on one carrier/BWP with a beam on the other carrier/BWP, otherwise the transmission performance may be greatly degraded due to beam misalignment.

In view of the above, the present application discloses a solution. Without conflict, embodiments and features in 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.

The application discloses a method used in a user equipment for wireless communication, which is characterized by comprising the following steps:

receiving first signaling in a first time window on a first sub-band;

receiving a first wireless signal in a second time window on a second sub-band, the first signaling being used to determine a first index,

the first index is used to determine the second subband from among V candidate subbands, the V being a positive integer greater than 1;

wherein the first signaling comprises scheduling information of the first wireless signal; at least one transmitting antenna port of the first wireless signal is quasi co-located with one antenna port of a first antenna port group, the first antenna port group being associated with the first index; a time interval between the first time window and the second time window is less than a first threshold, or the first signaling does not include a first domain; the first threshold is a positive real number, and the first domain indicates a transmitting antenna port of a wireless signal scheduled by signaling to which the first domain belongs; the first antenna port group includes a positive integer number of antenna ports.

As an embodiment, the problem to be solved by the present application is: in the case of cross-carrier or cross-BWP scheduling, when a UE receives data on another carrier or BWP with a beam on the scheduled carrier or scheduled BWP, transmission performance is degraded due to beam inaccuracy. The above method solves this problem by establishing a correlation between the first set of antenna ports and the first index.

As an embodiment, the method is characterized in that, when the UE cannot obtain the transmit antenna port information of the first wireless signal from the first signaling, the UE may assume that the transmit antenna port of the first wireless signal and the antenna ports in the predefined/configured first antenna port group are quasi co-located. The first antenna port group has a different definition/configuration for different ones of the V candidate subbands. The benefit of this approach is that it ensures that the UE can receive the first wireless signal with the most suitable receive beam on each of the V candidate subbands, ensuring reliability of data transmission on any one candidate subband.

As an embodiment, the above method has a benefit that a corresponding set of antenna port groups may be flexibly defined/configured for each of the V candidate subbands, ensuring that the UE can receive the first wireless signal with the most suitable receiving beam on each of the V candidate subbands.

As an embodiment, the method is characterized in that, for each of the V candidate subbands, a plurality of antenna port groups may be predefined/configured in advance, and the QCL relationship of the first wireless signal is determined by implicitly indicating one of the plurality of antenna port groups through the first signaling.

Although not shown, the UE may have several protocol layers above the L2 layer 305, including a network layer (e.g., IP layer) that terminates at the P-GW213 on the network side and an application layer that terminates at the other end of the connection (e.g., far end UE, server, etc.). The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides header compression for upper layer packets to reduce radio transmission overhead, security by ciphering the packets, and handover support for UEs between gnbs. The RLC sublayer 303 provides segmentation and reassembly of upper layer packets, retransmission of lost packets, and reordering of packets to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat reQuest). The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in one cell among the UEs. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for the UE and the gNB is substantially the same for the physical layer 301 and the L2 layer 305, but without the header compression function for the control plane. The Control plane also includes an RRC (Radio Resource Control) sublayer 306 in layer 3 (layer L3). The RRC sublayer 306 is responsible for obtaining radio resources (i.e., radio bearers) and configures the lower layers using RRC signaling between the gNB and the UE.

Example 4

Embodiment 4 illustrates a schematic diagram of an NR node and a UE as shown in fig. 4. Fig. 4 is a block diagram of a UE450 and a gNB410 in communication with each other in an access network.

gNB410 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 UE450 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 DL (Downlink), at the gNB410, upper layer data packets from the core network are provided to a controller/processor 475. The controller/processor 475 implements the functionality of layer L2. In the DL, the controller/processor 475 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the UE450 based on various priority metrics. Controller/processor 475 is also responsible for HARQ operations, retransmission of lost packets, and signaling to UE 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 UE450, 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 the DL (Downlink), at the UE450, 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 UE 450. The symbols on each spatial stream are demodulated and recovered at a receive processor 456 and soft decisions are generated. Receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the gNB410 on the physical channels. 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 the DL, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer data 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. The controller/processor 459 is also responsible for error detection using an Acknowledgement (ACK) and/or Negative Acknowledgement (NACK) protocol to support HARQ operations.

In the UL (Uplink), at the UE450, a data source 467 is used to provide upper layer data packets to the controller/processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function at the gNB410 described in the DL, the controller/processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the gNB410, implementing L2 layer functions for the user plane and the control plane. The controller/processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the gNB 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 UL (Uplink), the function at the gNB410 is similar to the reception function at the UE450 described in DL. 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 the UL, 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. Controller/processor 475 is also responsible for error detection using the ACK and/or NACK protocol to support HARQ operations.
