Efficient uplink feedback in a wireless communication system

摘要

A method for transmitting control information by transmitting a reference signal from a first transceiver to a second transceiver, in response to the reception of the reference signal, determining at the second transceiver a plurality of control channel elements based upon the received reference signal, jointly encoding the plurality of control channel elements at the second transceiver to generate a control signal, and transmitting the control signal from the second transceiver to the first transceiver.

1. A method for transmitting control information by a user equipment (UE), the method comprising:
receiving a reference signal from a first transceiver; in response to the reception of the reference signal, determining a plurality of control information based upon the received reference signal; jointly encoding the plurality of control information using a block code; modulating the encoded control information to generate a plurality of modulated symbols using a modulation scheme; multiplying a selected sequence with the modulated symbols to generate a plurality of multiplied sequences; mapping the plurality of multiplied sequences into two sets of resource elements in time and frequency domains in a subframe, the two sets of resource elements allocated to the UE,
a first set of the two sets of resource elements being located in one edge of the subframe in the frequency domain and in a first half of the subframe in the time domain, anda second set of the two sets of resource elements being located in an opposite edge of the subframe in the frequency domain and in a second half of the subframe in the time domain; and converting the mapped sequences to radio frequency signals for transmission.
