Description

Method and device in communication node for wireless communication
The application is a divisional application of the following original applications:
application date of the original application: 2018, 02 and 28 days
- -application number of the original application: 201810167081.2
The invention of the original application is named: method and device in 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-granted transmission scheme and apparatus.
Background
In the future, the application scenes of the wireless communication system are more and more diversified, and different application scenes put different performance requirements on the system. In order to meet different performance requirements of various application scenarios, a New air interface technology (NR, new Radio) (or 5G) is determined to be studied in 3GPP (3 rd Generation Partner Project) RAN (Radio Access Network) #72 fairs, and standardization Work on NR starts after passing through WI (Work Item) of the New air interface technology (NR, new Radio) in 3GPP RAN #75 fairs.
In order to adapt to various application scenarios and meet different requirements, a research project of Non-orthogonal Multiple Access (NoMA) under NR is also adopted in the 3gpp ran #76 conference, the research project starts at the R16 version, and WI is started to standardize the related technology after SI ends. Among the numerous NoMA transmission schemes, the Grant-Free uplink transmission is an important research scheme due to its advantages such as low complexity requirement on the receiver.
Disclosure of Invention
In the non-granted uplink transmission, especially in the case of RRC (Radio Resource Control) non-connected (RRC Inactive Mode or RRC Idle Mode), the uplink transmissions of different ues are not yet synchronized. Due to the non-synchronous transmission of the uplink, the timing complexity of the receiver can be reduced in the non-granted uplink transmission based on the Preamble sequence. In high frequency scenarios, large-scale antennas need to be deployed to combat penetration loss and transmission attenuation. Beam Sweeping (Beam Sweeping) can reduce the complexity of a radio frequency end while enhancing coverage by adopting analog Beam forming under the condition of a large-scale antenna, but the Beam Sweeping based on analog beams needs to occupy a large amount of time domain resources, so that the resource utilization rate is reduced. The problem of resource utilization reduction caused by Beam sweeping is more prominent because the Beam Training (Beam Training) and Beam Management (Beam Management) processes are not performed in the non-granted uplink transmission in the non-connection state. The application provides a solution for beam configuration in non-granted uplink transmission. It should be noted that, in case of no conflict, the embodiments and features in the embodiments in the base station apparatus of the present application may be applied to the user equipment, and vice versa.

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 the PHY301, and is responsible for a link between the first type of communication node device and the second type of communication node device through the 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 second type of communication node device on the network side.
