Abstract
Provided are a method for a terminal transmitting a sidelink in a wireless communication system, and a terminal using same. The method comprises: determining at least one sidelink subframe for sidelink transmission from subframes, in a set of all subframes, other than subframes having a sidelink synchronization signal (SLSS) resource configured, and reserved subframes; and transmitting the sidelink using the at least one sidelink subframe.

A method of performing sidelink transmission of a user equipment (UE) in a frequency division duplex (FDD) wireless communication system, the method comprising:
- performing sidelink transmission based on at least one subframe for sidelink transmission, where the at least one subframe for the sidelink transmission excludes, from a set of all subframes, (i) SLSS subframes in which a sidelink synchronization signal (SLSS) resource is configured and (ii) reserved subframes,
- wherein the reserved subframes are configured to satisfy the following condition:
- within subframes {l0, l1, . . . , l(10240−Nslss−1)} other than the SLSS subframes which are excluded from the set of all subframes, the reserved subframes are indexed by subframe index r that satisfies:
- wherein |*| represents a floor function,
- wherein Nslss represents a number of the SLSS subframes,
- wherein Nreserved=(10240-Nslss)mod Lbitmap represents a number of the reserved subframes, with Lbitmap representing a length of a bitmap that indicates the at least one subframe for the sidelink transmission.
A user equipment (UE) configured to operate in a frequency division duplex (FDD) wireless communication system, the UE comprising:
- a transceiver for transmitting and receiving a radio signal;
- and
- a processor operatively coupled to the transceiver,
- wherein the processor is configured to perform sidelink transmission based on at least one subframe for sidelink transmission, where the at least one subframe for the sidelink transmission excludes, from a set of all subframes, (i) SLSS subframes in which a sidelink synchronization signal (SLSS) resource is configured and (ii) reserved subframes,
- wherein the reserved subframes are configured to satisfy the following condition:
- within subframes {l0, l1, . . . , l(10240−Nslss−1)} other than the SLSS subframes which are excluded from the set of all subframes, the reserved subframes are indexed by subframe index r that satisfies:
- wherein |*| represents a floor function,
- wherein Nslss represents a number of the SLSS subframes,
- wherein Nreserved=(10240-Nslss)mod Lbitmap represents a number of the reserved subframes, with Lbitmap representing a length of a bitmap that indicates the at least one subframe for the sidelink transmission.
An apparatus comprising:
- a memory;
- and
- a processor operatively coupled to the memory,
- wherein the processor is configured to perform sidelink transmission based on at least one subframe for sidelink transmission, where the at least one subframe for the sidelink transmission excludes, from a set of all subframes, (i) SLSS subframes in which a sidelink synchronization signal (SLSS) resource is configured and (ii) reserved subframes,
- wherein the reserved subframes are configured to satisfy the following condition:
- within subframes {l0, l1, . . . , l(10240−Nslss−1)} other than the SLSS subframes which are excluded from the set of all subframes, the reserved subframes are indexed by subframe index r that satisfies:
- wherein |*| represents a floor function,
- wherein Nslss represents a number of the SLSS subframes,
- wherein Nreserved=(10240-Nslss)mod Lbitmap represents a number of the reserved subframes, with Lbitmap representing a length of a bitmap that indicates the at least one subframe for the sidelink transmission.
