-The name of the invention of the original application: method and apparatus in a communication node for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to an uplink non-grant transmission scheme and apparatus.

Background

Future wireless communication systems have more and more diversified application scenes, and different application scenes have different performance requirements on the system. To meet different performance requirements of various application scenarios, research on a New air interface technology (NR, new Radio) (or 5G) is decided at the 3GPP (3 rd Generation Partner Project, third generation partnership project) RAN (Radio Access Network ) #72 full-time, and standardization Work on NR is started at the 3GPP RAN #75 full-time WI (Work Item) that passes the New air interface technology (NR, new Radio).

In order to be able to adapt to various application scenarios and meet different requirements, a research project of Non-orthogonal multiple access (NoMA, non-orthogonal Multiple Access) under NR is also passed on the 3gpp ran#76 meeting, and the research project starts in R16 version, starts WI after SI ends, and standardizes related technologies. Among the numerous NoMA transmission modes, non-Grant-Free uplink transmission is one mode of important research due to its low complexity requirement of the receiver.

Disclosure of Invention

In the non-grant uplink transmission, especially in the RRC (Radio Resource Control ) non-connected state (RRC INACTIVE Mode or RRC Idle Mode), the uplink transmissions of different ues are not yet synchronized. The non-grant uplink transmission based on a Preamble sequence may reduce timing complexity of the receiver due to the uplink non-synchronous transmission. In high frequency scenarios, large-scale antennas need to be deployed to combat penetration and transmission attenuation. Beam sweeping (Beam Sweeping) can employ analog beamforming to enhance coverage in the case of large-scale antennas while reducing the complexity of the radio frequency end, but analog beam-based beam sweeping requires a large amount of time domain resources to occupy, resulting in reduced resource utilization. This problem of reduced resource utilization due to Beam sweep is further accentuated by the fact that Beam Management (Beam Management) has not been performed after Beam Training (Beam Training) during non-grant uplink transmissions in the non-connected state. The present application provides a solution for beam configuration in non-grant uplink transmission. It should be noted that embodiments of the base station apparatus and features of the embodiments of the present application may be applied to the user equipment and vice versa without conflict.

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 first type of communication node device and the second type of communication node device 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 are terminated at the second type of communication node device on the network side.
