US 12,471,117 B2 · Data transmission/reception method, device, and system in wireless communication system

Abstract

Disclosed is a method by which a terminal transmits a signal in a wireless communication system. The terminal can receive configuration information for setting a first subcarrier spacing (SCS) for a plurality of slots, and transmit a physical sidelink shared channel (PSSCH) in the plurality of slots. At this time, if the terminal coexists with a legacy terminal in a co-channel and the plurality of slots fully overlap a legacy subframe of the legacy terminal, second transmission power in at least one slot that excludes a first slot from among the plurality of slots can be limited by means of first transmission power of the first slot.

Claims14

Dependent claims

A terminal configured to operate in a wireless communication system, the terminal comprising:

a communication module;
and
a processor configured to control the communication module,
wherein the processor is configured to:
receive configuration information for configuring a first subcarrier spacing (SCS) for multiple slots;
and
transmit physical sidelink shared channel (PSSCH) transmissions in the multiple slots, and
wherein in case that the terminal coexists with a legacy terminal on a co-channel and the PSSCH transmissions in multiple slots overlap with a legacy subframe of the legacy terminal in a time domain, a second transmission power in at least one slot, other than a first slot, among the multiple slots for the PSSCH transmissions is configured to have a value that is not greater than a first transmission power in the first slot among the multiple slots for the PSSCH transmissions.
