Method and apparatus for sending data and control information in a wireless communication system
First Claim
1. A method for wireless communication implemented by a user equipment (UE), comprising:
- identifying control information to be sent to a base station in an uplink signal;
determining whether data is to be sent by the UE in the uplink signal;
processing the control information for the uplink signal in accordance with a first processing scheme to obtain at least one modulation symbol for the control information when the data is not to be sent by the UE;
processing the control information and the data for the uplink signal in accordance with a second processing scheme to obtain one or more modulation symbols for the control information and the data when the data is to be sent by the UE; and
transmitting the uplink signal to the base station.

Abstract
Techniques for sending control information in a communication system are described. In an aspect, control information may be sent in a first frequency location (e.g., a first set of subcarriers) if data is not being sent and in a second frequency location (e.g., a second set of subcarriers) if data is being sent. In another aspect, control information may be processed in accordance with a first processing scheme if data is not being sent and with a second processing scheme if data is being sent. In one design of the first scheme, a CAZAC sequence may be modulated with each modulation symbol for control information to obtain a corresponding modulated CAZAC sequence, which may be sent on the first set of subcarriers. In one design of the second scheme, modulation symbols for control information may be combined with modulation symbols for data, transformed to frequency domain, and mapped to the second set of subcarriers.
