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, a base station needs to transmit 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 less than a threshold, the UE receives the downlink data by using a predefined or default beam associated on the control channel.

Disclosure of Invention

The inventors discovered through research that for a UE supporting carrier aggregation (carrieraggereration), downlink data and corresponding scheduling signaling may come from different carriers. In this case, the UE cannot receive data on one carrier with a beam on another carrier, otherwise the transmission performance is greatly reduced due to the 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.

Fig. 3 is a schematic diagram illustrating an embodiment of radio protocol architecture for the user plane and the control plane, fig. 3 showing the radio protocol architecture for the UE and the gNB in three layers: layer 1, layer 2 and layer 3. 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 PHY 301. Layer 2(L2 layer) 305 is above PHY301 and is responsible for the link between the UE and the gNB through PHY 301. In the user plane, the L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the gNB on the network side. 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.

Example 6

Embodiment 6 illustrates a schematic diagram of antenna ports and antenna port groups; as shown in fig. 6.

In embodiment 6, one antenna port group includes a positive integer number of antenna ports; one antenna port is formed by superposing antennas in a positive integer number of antenna groups through antenna Virtualization (Virtualization); one antenna group includes a positive integer number of antennas. One antenna group is connected to the baseband processor through one RF (Radio Frequency) chain, and different antenna groups correspond to different rfchains. The mapping coefficients of all antennas in the positive integer number of antenna groups included by a given antenna port to the given antenna port constitute a beamforming vector corresponding to the given antenna port. Mapping coefficients of a plurality of antennas included in any given antenna group in the positive integer number of antenna groups included in the given antenna port to the given antenna port constitute an analog beamforming vector of the given antenna group. And the diagonal arrangement of analog beamforming vectors corresponding to a positive integer number of antenna groups included in the given antenna port forms an analog beamforming matrix corresponding to the given antenna port. The given antenna port comprises a positive integer number of antenna groups, and mapping coefficients of the given antenna port form a digital beamforming vector corresponding to the given antenna port. The beamforming vector corresponding to the given antenna port is obtained by multiplying an analog beamforming matrix corresponding to the given antenna port by a digital beamforming vector. Different antenna ports in one antenna port group are formed by the same antenna group, and different antenna ports in the same antenna port group correspond to different beam forming vectors.

Two antenna port groups are shown in fig. 6: antenna port group #0 and antenna port group # 1. The antenna port group #0 is composed of an antenna group #0, and the antenna port group #1 is composed of an antenna group #1 and an antenna group # 2. Mapping coefficients of a plurality of antennas in the antenna group #0 to the antenna port group #0 constitute an analog beamforming vector #0, and mapping coefficients of the antenna group #0 to the antenna port group #0 constitute a digital beamforming vector # 0. Mapping coefficients of the plurality of antennas in the antenna group #1 and the plurality of antennas in the antenna group #2 to the antenna port group #1 constitute an analog beamforming vector #1 and an analog beamforming vector #2, respectively, and mapping coefficients of the antenna group #1 and the antenna group #2 to the antenna port group #1 constitute a digital beamforming vector # 1. A beamforming vector corresponding to any antenna port in the antenna port group #0 is obtained by a product of the analog beamforming vector #0 and the digital beamforming vector # 0. A beamforming vector corresponding to any antenna port in the antenna port group #1 is obtained by multiplying an analog beamforming matrix formed by diagonal arrangement of the analog beamforming vector #1 and the analog beamforming vector #2 by the digital beamforming vector # 1.

As an example, an antenna port set includes only one antenna group, i.e., one RFchain, e.g., the antenna port set #0 in fig. 6.

As a sub-implementation of the foregoing embodiment, the analog beamforming matrix corresponding to the antenna ports in the one antenna port group is reduced to an analog beamforming vector, the digital beamforming vector corresponding to the antenna ports in the one antenna port group is reduced to a scalar, and the beamforming vector corresponding to the antenna ports in the one antenna port group is equal to its corresponding analog beamforming vector. For example, the antenna port set #0 in fig. 7 includes only the antenna set #0, the digital beamforming vector #0 in fig. 6 is reduced to a scalar, and the beamforming vector corresponding to the antenna port in the antenna port set #0 is the analog beamforming vector # 0.

As a sub-embodiment of the above-described embodiment, the one antenna port group includes 1 antenna port.

As an embodiment, one antenna port group includes a plurality of antenna groups, i.e., a plurality of rfchains, for example, the antenna port group #1 in fig. 6.

As an embodiment, any two antenna ports in a group of antenna ports are quasi co-located.

As an embodiment, the quasi-co-location of one antenna port and another antenna port means: the one antenna port and the another antenna port QCL (Quasi Co-Located).

As an example, the specific definition of QCL is seen in section 5.1.5 of 3gpp ts 38.214.

As an embodiment, the quasi-co-location of one antenna port and another antenna port means: all or part of the large-scale (properties) characteristics of the wireless signal transmitted on the other antenna port can be deduced from all or part of the large-scale (properties) characteristics of the wireless signal transmitted on the one antenna port.
