Description

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

Technical Field

The present application relates to a transmission method and apparatus in wireless communication, and more particularly, to a method and apparatus for performing wireless relay (Relaying) using a terminal device.

Background

In 3GPP (3rd Generation Partner Project) Release 12, D2D (Device to Device) communication is established and discussed, and an essential feature of D2D is to allow data transfer between UEs (User Equipment). In the current Mode 1 transmission Mode in D2D transmission, a base station sends a resource occupied by a data channel on a Sidelink (Sidelink) to a sending terminal in D2D transmission through DCI (Downlink Control Information), and then the sending terminal sends the resource occupied by the data channel to a receiving terminal in D2D transmission through SCI (Sidelink Control Information) and simultaneously sends the data channel corresponding to the SCI to the receiving terminal in D2D transmission, so as to implement data communication.

In the discussion of 3GPP regarding 5G, SI (Study Item) regarding FeD2D (futher enhancements to LTE D2D, Further enhanced inter-device communication) has been established and discussed in 3 GPP. One feature of the FeD2D is that wireless relay transmission is performed by the terminal device under the architecture of Release 12D 2D.

Disclosure of Invention

An important feature of Release 12D2D is that feedback on Sidelink (Sidelink or PC5 link) is not supported, whereas an important enhancement in FeD2D is the need to feedback to the network side the transmission quality on PC5 link. Researchers find through research that a direct implementation manner is that a base station configures an independent time-frequency resource for a PC5 link on a Cellular link, and a receiving end of D2D transmission sends feedback information for the PC5 link on the time-frequency resource. However, one problem with this approach is that, considering the False Alarm (False Alarm) problem of two-hop reception of DCI and SCI, the receiving end in D2D communication does not always send the transmission quality for the PC5 link, and the fixed reservation of the time-frequency resources may occupy too much time-frequency resources on the Cellular link, resulting in a reduction in spectral efficiency.

The present application provides a solution to the above problems. It should be noted that the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict. For example, embodiments and features in embodiments in the user equipment of the present application may be applied in the base station and vice versa.

Example 3

Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for the user plane and the control plane according to the present application, 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 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.

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).

Example 4

Embodiment 4 shows a schematic diagram of an evolved node and a given user equipment according to the present application, 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 eNB 410. 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 UL, 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 a data sink 462, which represents all protocol layers above the L2 layer. Various control signals may also be provided to the data sink 462 for processing by the L3. 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. 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.
