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 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 difficulties in allocating radio resources for uplink transmission, and since the base station cannot know the load size required for enhanced CSI feedback in advance, the base station cannot reserve radio resources of a suitable size for CSI feedback. How to solve the problem that resource waste caused by too much wireless resources reserved by a base station or CSI feedback cannot be completely sent caused by too little wireless resources reserved by the base station is needed to be solved.

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. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.

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

when the CSI feedback and the uplink data are sent together on the uplink physical layer data channel and the base station does not know the load size of the CSI feedback in advance, if the radio resource allocated to the CSI feedback by the base station exceeds the actual requirement, the UE may send additional uplink data on the redundant radio resource, thereby avoiding resource waste caused by excessive resource allocated to the CSI feedback and improving the resource utilization rate. Or, the UE may repeatedly transmit the scheduled uplink data on the redundant radio resources, thereby improving the transmission reliability of the uplink data.

The base station can allocate wireless resources to the CSI feedback according to the maximum possible load size, so that the situation that the CSI cannot be completely fed back due to insufficient resource allocation is avoided.

The extra transmitted uplink data and the scheduled uplink data belong to the same TB, simplifying the processing at the MAC layer.

The actual load size of the CSI feedback does not affect the transmission of the scheduled uplink data, thereby ensuring that the scheduled uplink data can still be received when the base station fails to receive the CSI feedback.

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 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. 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 channel encoder 477, a channel decoder 478, a transmitter/receiver 418, and an antenna 420.

The UE450 includes a controller/processor 459, memory 460, a data source 467, a transmit processor 468, a receive processor 456, a channel encoder 457, a channel decoder 458, a transmitter/receiver 454, and an antenna 452.

In the DL (Downlink), at the gNB, 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 allocation of radio resources for 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 channel encoder 477 perform various signal processing functions for the L1 layer (i.e., the physical layer). Channel encoder 477 performs coding and interleaving to facilitate Forward Error Correction (FEC) at UE 450. Transmit processor 416 performs mapping for 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)) and performs spatial precoding/beamforming on the encoded 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. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the transmit processor 416 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. The receive processor 456 and channel decoder 458 implement the various signal processing functions of the L1 layer. Receive processor 456 converts the 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 physical layer data is recovered into spatial streams destined for the UE450 through multi-antenna detection in the receive processor 456. The symbols on each spatial stream are demodulated and recovered at a receive processor 456 and soft decisions are generated. Channel decoder 458 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the gNB410 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 functionality of 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 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. The channel encoder 457 performs channel encoding and the encoded data is modulated into a multi-carrier/single-carrier symbol stream by modulation performed by the transmit processor 468 and multi-antenna spatial precoding/beamforming processing and provided to different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the transmit processor 468 into a radio frequency symbol stream that is provided 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 radio frequency signals through its respective antenna 420, converts the received radio frequency signals to baseband signals, and provides the baseband signals to a receive processor 470. Receive processor 470 and channel decoder 478 together implement the functions of layer L1. 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 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.

A block diagram of circuitry for generating a block of CRC bits for the given block of information bits is shown in fig. 20. { the given information bit block, the given check bit block } is any one of { { the first control information in this application, the CRC bit block of the first control information }, { the second control information in this application, the CRC bit block of the second control information }, { the first data in this application, the fourth check bit block in this application }, { the second data in this application, the second check bit block in this application }, { the first combined data in this application, the first check bit block in this application }, { the second combined data in this application, the third check bit block in this application }, { the first residual data in this application, the fourth check bit block in this application } }.

In fig. 20, the CRC loop generator polynomial is represented as: g_LD^L+…+g₁D+g₀Wherein { g₀,g₁,…,g_L-is the coefficients of the CRC cyclic generator polynomial, L being the number of bits in the CRC bit block of the given information bit block, the value of any one of the coefficients of the CRC cyclic generator polynomial belonging to {0, 1 }. The circuit of fig. 20 includes a shift register sequence of L shift registers, two switches, L +1 taps, and L exclusive-or operators. The L +1 taps are respectively located at two ends of the L shift registers, as shown in fig. 20. The indexes of the L shift registers are # {0, 1, … and L-1} respectively, and the indexes of the two change-over switches are # {0 and 1} respectively.

The change-over switch #0 is then switched back to position 1 in fig. 20, and the remaining bits in the given block of information bits continue to be sequentially input into the shift register sequence of L shift registers while being sequentially output. The above process is repeated 1 or more times until all bits in the given block of information bits are input into the shift register sequence of L shift registers. Then, the position of the change-over switch #0 is switched to the position 2 in fig. 20, and all or a part of the values in the L shift registers are sequentially output, and the change-over switch #1 is sequentially switched to the corresponding position. The output of the switch #0 at position 2 in fig. 20 constitutes the CRC bit block of the given information bit block.
