US 11,122,527 B2 · Method and apparatus for performing data transmission based on multiple transmission time intervals, for transmitting control information, and for transmitting data by employing multiple ports

Abstract

The disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). A method for operating a terminal is provided. The method includes detecting, scheduling assignment (SA) of another terminal in a sensing window based on transmission time intervals (TTIs) with different lengths in a resource pool; detecting a receiving power of a scheduled data channel based on the SA and a receiving energy of each sub-channel of each subframe; determining resources for data transmission based on the SA, the receiving power and the receiving energy; and transmitting data on the resources.

Dependent claims

A first terminal in a wireless communication system, the first terminal comprising:

a transceiver;
and
at least one processor operably coupled to the transceiver, wherein the at least one processor is configured to:
receive control information on a physical sidelink control channel (PSCCH) for a second terminal, wherein the control information includes information on resources for a physical sidelink shared channel (PSSCH) scheduled by the PSCCH,
identify a reference signal received power (RSRP) of the PSSCH,
identify a resource set for a data transmission based on comparing the RSRP and a threshold, and
transmit data based on the resource set,
wherein the threshold is identified based on a length of a transmission time interval (TTI) of the PSSCH among a plurality of TTIs.
