Description

Method and device for downlink information transmission in UE (user equipment) and base station

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and in particular, to a transmission scheme and apparatus for downlink information.

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, research on New air interface technology (NR, New Radio) (or 5G) is decided on 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 global meetings.

To be able to adapt to a variety of different application scenarios, future wireless communication systems, in particular NR, will support a variety of mathematical structures (Numerology), which refers to a variety of subcarrier spacings, a variety of symbol time lengths, a variety of CP (Cyclic Prefix) lengths, etc. Meanwhile, in order to design the System more flexibly, the System Information (SI) in the NR System is divided into the Minimum set of System information (Minimum SI) that is periodically transmitted and the System information transmitted according to the requirement (On-Demand). The System Information of the Minimum set in turn comprises the System Information transmitted in a BCH (Broadcast Channel) and the System Information of the Remaining Minimum Sets (RMSI). The RMSI may be transmitted over a data channel in accordance with the conclusion of 3GPP RAN1# 88.

Disclosure of Invention

The transmission of the RMSI over the data channel can be achieved in two ways: one is that a data channel for transmitting the RMSI is scheduled by Downlink Control Information (DCI); in another example, the data channel for transmitting the RMSI is not scheduled by Downlink Control Information (DCI). If the downlink control information is used for scheduling, additional signaling overhead is introduced, and especially in consideration of a scenario (for example, carrier frequency is above 6 GHz) where the amount of information carried by the RMSI is limited and Beam Sweeping (Beam Sweeping) is required, the burden of the signaling overhead is very significant. When the data channel of the RMSI is transmitted by using a non-DCI scheduling method, due to lack of DCI scheduling or PBCH transmission scheduling information limitation, the configuration flexibility of the data channel for transmitting the RMSI is very limited, which is not favorable for multiplexing transmission with other channels and meets the requirements of future system development.

Aiming at the problems of large RMSI transmission head overhead and limited RMSI transmission flexibility, the application provides a compromise solution. By adopting the solution of the application, in the process of transmitting the RMSI, the overlarge head overhead caused by DCI scheduling is avoided, and meanwhile, certain configuration flexibility can be provided. It should be noted that, without conflict, the embodiments and features in the embodiments in the UE (User Equipment) of the present application may be applied to the base station, and vice versa.
