Description

Method and device used in user and base station of wireless communication Technical Field
The present application relates to a method and an apparatus for transmitting a radio signal in a wireless communication system, and more particularly, to a method and an apparatus for transmitting a radio signal in a wireless communication system supporting uplink control information.
Background
In a wireless communication system supporting multi-antenna transmission, it is a common technique for a UE (User Equipment) to feed back CSI (Channel Status Information) to assist a base station to perform multi-antenna processing. Implicit (im) CSI feedback is supported in legacy third generation partnership Project (3 GPP-3 rd generation partner Project) cellular network systems. In a conventional LTE (Long Term Evolution) system, when a UE needs to send CSI feedback and uplink data simultaneously on one sub-frame, the CSI feedback may be sent on an uplink physical layer data channel together with the data.
In the 5G system, as the number of antennas equipped on the base station side increases, the accuracy of the conventional implicit CSI feedback is difficult to meet the requirement of multi-antenna transmission. Therefore, studies for enhancing CSI are proposed in 3GPP R (Release) 14. The feedback Overhead (Overhead) required for the enhanced CSI is increased greatly, and thus, the feedback design for the enhanced CSI is a problem to be solved.
Disclosure of Invention
The inventors have found through research that the payload size (payload size) required for enhanced CSI feedback is different under different channel conditions, and the variation of such payload size is dynamic. Such dynamic load size changes may cause a bias in the understanding of the load size of CSI feedback by both parties of wireless communication. When the enhanced CSI feedback is transmitted on the uplink physical layer data channel along with the uplink data, this deviation from understanding will cause difficulty in the correct decoding of the uplink data.
In view of the above, the present application discloses a solution. It should be noted that although the initial motivation of the present application was for multi-antenna systems, the present application is also applicable to single-antenna systems. 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.

As an example, compared with the conventional scheme, the method has the following advantages:
in conventional LTE systems, the number of resource elements occupied by CSI feedback on the uplink physical layer data channel is fixed. The method in the application allows the UE to dynamically select the content and the load size of the CSI feedback according to the actual channel state, and dynamically adjust the number of the resource particles occupied by the CSI feedback on the uplink physical layer data channel according to the actual load size, thereby avoiding the waste of air interface resources caused by the number of the resource particles occupied by the fixed CSI feedback on the uplink physical layer data channel.
The resource element occupied by the CSI feedback on the uplink physical layer data channel is divided into two parts, fixed and dynamically varying. The dynamically changed part is reserved for uplink data which is transmitted together with CSI feedback, so that the understanding deviation of the modulation coding mode of the uplink data caused by the understanding deviation of the load size of the CSI feedback by both wireless communication parties is avoided, and the condition that the uplink data cannot be decoded caused by the understanding deviation is also avoided. The fixed and unchangeable part is reserved for CSI feedback, so that the great reduction of the receiving quality of the uplink data caused by the fact that the CSI feedback occupies too much air interface resources reserved for the uplink data is avoided. The method can well balance the utilization efficiency of the wireless resources and the receiving quality of the uplink data.

Embodiment 3 illustrates a schematic diagram of an embodiment of radio protocol architecture for the user plane and the control plane, as shown in fig. 3.
Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and the control plane, fig. 3 showing the radio protocol architecture for the UE and the eNB 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 eNB 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 an eNB on the network side. Although not shown, the UE may have several upper 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 data packets to reduce radio transmission overhead, security by ciphering the data packets, and handover support for UEs between enbs. 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. 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 eNB 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 eNB and the UE.

Example 4
Embodiment 4 illustrates a schematic diagram of an evolved node and a UE, as shown in fig. 4.
Fig. 4 is a block diagram of an eNB410 in communication with a UE450 in an access network. In the DL (Downlink), upper layer packets from the core network are provided to the 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 implements various signal processing functions for the L1 layer (i.e., the physical layer). The signal processing functions include decoding and interleaving to facilitate Forward Error Correction (FEC) at the UE450 and mapping to 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 coded and modulated symbols are then split into parallel streams. Each stream is then mapped to a multicarrier subcarrier, multiplexed with a reference signal (e.g., pilot) in the time and/or frequency domain, and then combined together using an Inverse Fast Fourier Transform (IFFT) to produce a physical channel carrying a time-domain multicarrier symbol stream. The multi-carrier stream is spatially pre-decoded to produce a plurality of spatial streams. Each spatial stream is then provided via a transmitter 418 to a different antenna 420. Each transmitter 418 modulates an RF carrier with a respective spatial stream for transmission. At the UE450, each receiver 454 receives a signal through its respective antenna 452. Each receiver 454 recovers information modulated onto an RF carrier and provides the information to a receive processor 456. The receive processor 456 performs various signal processing functions at the L1 level. The receive processor 456 performs spatial processing on the information to recover any spatial streams destined for the UE 450. If multiple spatial streams are destined for UE450, they may be combined into a single multicarrier symbol stream by receive processor 456. A receive processor 456 then converts the multicarrier symbol stream from the time-domain to the frequency-domain using a Fast Fourier Transform (FFT). The frequency domain signal comprises a separate multicarrier symbol stream for each subcarrier of the multicarrier signal. The symbols on each subcarrier, as well as the reference signal, are recovered and demodulated by determining the most likely signal constellation point transmitted by the eNB410, and generating soft decisions. The soft decisions are then decoded and deinterleaved to recover the data and control signals that were originally transmitted by the eNB410 on the physical channel. The data and control signals are then provided to a controller/processor 459. The controller/processor 459 implements the L2 layer. The controller/processor can 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 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. 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), a data source 467 is used to provide the upper layer packet to the controller/processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the functionality described in connection with the DL transmission of the eNB410, the controller/processor 459 implements the L2 layer for the user plane and the control plane by providing header compression, ciphering, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the eNB 410. The controller/processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the eNB 410. An appropriate coding and modulation scheme is selected and spatial processing is facilitated by a transmit processor 468. The spatial streams generated by the transmit processor 468 are provided to different antennas 452 via separate transmitters 454. Each transmitter 454 modulates an RF carrier with a respective spatial stream for transmission. The UL transmissions are processed at the eNB410 in a manner similar to that described in connection with the receiver functionality at the UE 450. Each receiver 418 receives a signal through its respective antenna 420. Each receiver 418 recovers information modulated onto an RF carrier and provides the information to a receive processor 470. Receive processor 470 may implement the L1 layer. The controller/processor 475 implements the L2 layer. 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 packets from the controller/processor 475 may be provided to the core network. Controller/processor 475 is also responsible for error detection using the ACK and/or NACK protocol to support HARQ operations.
