Method of resolving overlaps in data transmission and user equipment therefor
First Claim
1. A method of transmitting symbols by a user equipment in a wireless communication, each symbol including a cyclic prefix and a data part, the method comprising:
- receiving, by the user equipment, a timing adjustment command from a base station, the timing adjustment command indicating an advance of uplink transmission timing relative to a current uplink transmission timing;
transmitting, by the user equipment, a first symbol to which the current uplink transmission timing is applied to the base station; and
transmitting, by the user equipment, a second symbol to which the timing adjustment command is applied to the base station,wherein, when the first symbol and the second symbol are overlapped due to the timing adjustment command, the first symbol is transmitted completely and an overlapped part of the second symbol is not transmitted.

Abstract
A user equipment and corresponding method of transmitting symbol by the user equipment in a wireless communication. The user equipment transmits a plurality of symbols to a base station, each symbol including a cyclic prefix and a data part. The method includes: receiving a timing adjustment command from the base station, the timing adjustment command advancing a transmission timing of symbol after a predetermined time; and transmitting a timing adjusted symbol to the base station. A length of the timing adjusted symbol is varied so that the timing adjusted symbol does not include an overlapping part with a previous symbol.

9. A user equipment used for a wireless communication system, wherein the user equipment transmits symbols to a base station, each symbol including a cyclic prefix and a data part, the user equipment comprising:
-
a wireless communication unit configured to receive a transmission timing adjustment command from the base station, the timing adjustment command indicating an advance of uplink transmission timing relative to a current uplink transmission timing, transmit a first symbol to which the current uplink transmission timing is applied to the base station, the non-timing adjusted symbol being a complete symbol, and transmit a second symbol to which the timing adjustment command is applied to the base station; and a symbol generation unit, wherein, when the first symbol and the second symbol are overlapped due to the timing adjustment command, the first symbol is transmitted completely and an overlapped part of the second symbol is not transmitted. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
