Method and device used in user equipment and base station for 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 a cellular network.

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 the cellular system 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) to avoid interference due to multiple transmitters simultaneously occupying the same frequency resources. A transmitter of the LTE system employs a quasi-omni antenna to perform LBT.

Currently, a technical discussion of 5G NR (New Radio Access Technology) is underway, wherein Massive MIMO (Multi-Input Multi-Output) becomes a research hotspot of next-generation mobile communication. In massive MIMO, multiple antennas form a beam pointing to a specific spatial direction through Beamforming (Beamforming) to improve communication quality, and when considering coverage characteristics caused by Beamforming, the conventional LAA technique needs to be considered again, such as LBT scheme.

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 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.

As an example, the radio protocol architecture in fig. 3 is applicable to the user equipment in the present application.

A beamforming vector corresponding to any antenna port in the antenna port group #0 is obtained by a product of the analog beamforming vector #0 and the digital beamforming vector #0. A beamforming vector corresponding to any antenna port in the antenna port group #1 is obtained by multiplying an analog beamforming matrix formed by diagonal arrangement of the analog beamforming vector #1 and the analog beamforming vector #2 by the digital beamforming vector #1.
