Method and apparatus for transmitting and receiving different signal types in communication systems
First Claim
1. A method for transmitting a Reference Signal (RS) of a User Equipment (UE) in a wireless communication system, the method comprising:
- transmitting a Sounding Reference Signal (SRS) during one symbol in a sub-frame;
transmitting a DeModulation (DM) RS during one symbol of each slot in another sub-frame; and
transmitting an information signal during other symbols of each slot in the another sub-frame over a same bandwidth as the DM RS.

Abstract
A method and apparatus for multiplexing a reference signal from a User Equipment (UE), not having any other signal transmission in the respective Transmission Time Interval (TTI), with a reference signal from another UE also having data transmission in the respective TTI, or with the control signal and reference signal from another UE transmitted in the respective TTI. The multiplexed reference signal from the UE not having any other signal transmission in the respective TTI can serve as a sounding reference signal to enable the serving base station to apply link adaptation to a subsequent signal transmitted by the UE or it can serve as a reference signal conveying state information, such as resource request or service request.
