The invention of the original application is named: 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 a wireless communication system, and more particularly, to a communication method and apparatus supporting data transmission over an Unlicensed Spectrum (Unlicensed Spectrum).

Background

In a conventional 3GPP (3 rd Generation Partner Project) LTE (Long-term Evolution) system, data transmission can only occur on a licensed spectrum, however, with a drastic increase in traffic, especially in some urban areas, the licensed spectrum may be difficult to meet the traffic demand. Communication over unlicensed spectrum in Release 13 and Release 14 was introduced by cellular systems and used for transmission of downlink and uplink data. To ensure compatibility with other Access technologies over unlicensed spectrum, LBT (Listen Before Talk) technology is adopted by LAA (Licensed Assisted Access) of LTE to avoid interference due to multiple transmitters simultaneously occupying the same frequency resources. LBT in LTE systems is wideband, i.e. the bandwidth of LBT is typically the same as the bandwidth of CC (Component Carrier).

The 5G NR (New Radio Access Technology ) Phase 1 (stage 1) system introduces the concept of BWP (Bandwidth Part) in CC for better supporting UEs (User Equipment) with different receiving Bandwidth and transmitting Bandwidth capabilities. When a UE with larger bandwidth capability communicates with a cell, the UE may perform downlink reception or uplink transmission on a BWP with larger bandwidth. NR Release 16 is discussing access techniques for unlicensed spectrum, it has been presently agreed to adopt sub-band (Subband) LBT, whose bandwidth is an integer multiple of 20MHz, which may be equal to or smaller than the bandwidth of BWP.

Disclosure of Invention

The inventor finds that, compared with wideband LBT of LTE system, NR system using sub-band LBT can improve channel access opportunity, and also result in more dynamic change of actually occupied resource, in which case how to improve transmission reliability is a key issue to be solved.

In view of the above, the present application discloses a solution. 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.

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 User Equipment (UE) and the base station equipment (gNB or 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 PHY301. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the UE and the gNB through PHY301. 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 upper layers above the L2 layer 305, including a network layer (e.g., IP layer) that terminates at the P-GW 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 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 a RRC (Radio Resource Control) sublayer 306 in layer 3 (L3 layer). 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.
