METHOD AND APPARATUS FOR SIMULTANEOUS TRANSMISSION OF DOWNLINK HARQ-ACK AND SR
First Claim
Patent Images
1. A method of transmitting a Hybrid Automatic Repeat reQuest (HARQ) response from a User Equipment (UE) to a base station, the method comprising:
- establishing a Radio Resource Control (RRC) connection with the base station through a first serving cell, the first serving cell supporting a Frequency Division Duplex (FDD) mode;
receiving, at the UE, an RRC message through the first serving cell, the RRC message comprising carrier aggregation (CA) configuration information, the CA configuration information comprising information of a second serving cell supporting a Time Division Duplex (TDD) mode, and the first serving cell and the second serving cell being aggregated by an FDD-TDD CA scheme;
receiving a transport block through the first serving cell;
mapping a bit for the HARQ response in association with the received transport block; and
transmitting the HARQ response using resources for a Scheduling Request (SR) in a Physical Uplink Control Channel (PUCCH), the PUCCH being transmitted to the base station through the first serving cell.
