Abstract

The invention discloses a method and an apparatus in a node for wireless communication. The method comprises the steps of: enabling a node to receive first information, wherein the first information is used for determining X alternative formats; sending a first signal, wherein the first signal adopts a first format; sending a second signal, wherein the second signal adopts a second format, wherein the first format is one alternative format in the X alternative formats, and the second format is one alternative format in the X alternative formats, a first timing offset value is used for determining the sending timing of the first signal, a second timing offset value is used for determining the sending timing of the second signal, the first timing offset value and the second timing offset value are not equal, the first format is related to the first timing offset value, the second format is related to the second timing offset value, and the first signal and the second signal are both used for random access. The random access performance is improved.

Description

technical field [0001] The present application relates to a transmission method and device in a wireless communication system, in particular to a transmission scheme and device for random access in wireless communication. Background technique [0002] The application scenarios of future wireless communication systems are becoming more and more diversified, and different application scenarios put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, the new air interface technology (NR, New Radio) (or 5G) research, passed the WI (Work Item, work item) of the new air interface technology (NR, New Radio) at the 3GPP RAN#75 plenary meeting, and started to standardize NR. [0003] In order to adapt to various application scenarios and meet different needs, the 3GPP RAN#75 plenary meeting also passed the research project of non-terrestrial networks (NTN, Non-Terrestrial Networks) under ...
