Method of uplink control information transmission

摘要

A method of uplink control information transmission for a mobile device with carrier aggregation in a wireless communication system is disclosed. The method comprises being configured a plurality of cells including a primary cell and at least a secondary cell by a network of the wireless communication system, determining to transmit the uplink control information in a transmission time interval, and when the primary cell has no uplink resource for the uplink control information transmission, transmitting the uplink control information on at least a secondary cell having uplink resources in the TTI.

1. A method of uplink control information transmission for a mobile device with carrier aggregation in a wireless communication system, the method comprising:
being configured a plurality of cells including a primary cell and at least a secondary cell by a network of the wireless communication system, wherein the primary cell is a Time Division Duplex (TDD) system, and is configured a TDD uplink and downlink configuration; when determining to transmit an uplink control information on the primary cell in a subframe of a transmission time interval (TTI), but the subframe in the TTI on the primary cell is configured as a downlink subframe according to the TDD uplink and downlink configuration, transmitting the uplink control information on the at least a secondary cell in the TTI; wherein the transmitting step comprises: determining whether an uplink grant is assigned for any of the at least a secondary cell; when the uplink grant is assigned for the at least a secondary cell, transmitting the uplink control information on the uplink grant of one secondary cell with the highest priority among the secondary cells assigned with the uplink grant; and when no uplink grant is assigned for any of the at least secondary cell, transmitting the uplink control information on a physical uplink control channel (PUCCH) of one secondary cell with the highest priority among PUCCH available secondary cells of the at least a secondary cell.
