Number of the original application: 201910165255.6

-The name of the invention of the original application: user equipment, method and device in base station for wireless communication

Technical Field

The present application relates to transmission methods and apparatus in wireless communication systems, and more particularly to communication methods and apparatus supporting data transmission over unlicensed spectrum (Unlicensed Spectrum).

Background

In the conventional 3GPP (3 rd Generation Partner Project, third generation partnership project) LTE (Long-term Evolution) system, data transmission can only occur on the licensed spectrum, however, with the rapid increase of the traffic, especially in some urban areas, the licensed spectrum may be difficult to meet the traffic demand. Communications on unlicensed spectrum in Release 13 and Release 14 are introduced by the cellular system and used for transmission of downlink and uplink data. To ensure compatibility with access technologies on other unlicensed spectrum, LBT (Listen Before Talk, listen-before-talk) technology is adopted by LAA (LICENSED ASSISTED ACCESS, licensed spectrum assisted access) of LTE to avoid interference due to multiple transmitters simultaneously occupying the same frequency resources. The LBT is wideband in the LTE system, i.e. the bandwidth of the LBT is typically the same as the bandwidth of CC (Component Carrier).

The 5GNR (New Radio Access Technology ) Phase1 (Phase 1) system introduces the concept of BWP (Bandwidth Part) in the CC for better supporting UEs (User Equipment) with different reception bandwidths and transmission bandwidths capabilities. When a UE with a larger bandwidth capability communicates with a cell, the UE may perform downlink reception or uplink transmission on a BWP with a larger bandwidth. NR RELEASE 16 in the discussion about access techniques for unlicensed spectrum, it has been agreed that sub-band (Subband) LBT is currently adopted, the bandwidth of which is an integer multiple of 20MHz, which may be equal to or smaller than the bandwidth of BWP.

Disclosure of Invention

The inventor finds through research that compared with wideband LBT of the LTE system, the NR system adopts subband LBT to improve channel access opportunity, and also causes more dynamic change of actually occupied resources, and how to improve transmission reliability in this case is a key problem to be solved.

In view of the above, the present application discloses a solution. It should be noted that the embodiments of the present application and the features in the embodiments may be arbitrarily combined with each other without collision.

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, radio link layer control protocol) sublayer 303 and a PDCP (PACKET DATA Convergence Protocol ) sublayer 304, which terminate at the gNB on the network side.

The control plane also includes an RRC (Radio Resource Control ) sub-layer 306 in layer 3 (L3 layer).
