Abstract

The present application discloses a method and apparatus in a node for wireless communication. The node receives first information; receives first signaling; sends a first signal; the first information is used to determine a first set of characteristic parameters, the first signaling is used to determine a target from a first set of time lengths time length, the first characteristic parameter group includes at least one of the type of the sender of the first information, the height of the sender of the first information, and a common time offset; the first time length set is an alternative time length set in X candidate time length sets; the first characteristic parameter group is used to determine the first time length set from the X candidate time length sets; the target The time length and the common time offset are used together to determine the length of the time interval between the moment of reception of the first signaling and the moment of transmission of the first signal. This application guarantees successful uplink transmission.

Description

technical field [0001] The present application relates to a transmission method and device in a wireless communication system, and in particular, to a transmission scheme and device with a large delay in wireless communication. Background technique [0002] The application scenarios of future wireless communication systems are becoming more and more diversified, and different application scenarios place different performance requirements on the system. In order to meet the different performance requirements of various application scenarios, at the 72nd plenary meeting of RAN (Radio Access Network, Radio Access Network) of 3GPP (3rd Generation Partner Project), it was decided that the new air interface technology (NR, New Radio) (or 5G) research, passed the WI (Work Item, work item) of New Radio Technology (NR, New Radio) at the 3GPP RAN#75 plenary meeting, and began to standardize NR. [0003] In order to be able to adapt to various application scenarios and meet different ...
