Patent ID: 8451915

Claim:
A method for transmitting control information, 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 selected modulation scheme; multiplying a selected sequence with the modulated symbols to generate a plurality of multiplied sequences; identifying available transmission resources comprised of a plurality of equal duration resource elements in time and frequency domain, with each resource element corresponding to a respective one of a plurality of subcarriers, and a number of the subcarriers being equal to a number of elements within each of the plurality of multiplied sequences; mapping the plurality of multiplied sequences into two sets of resource elements in time and frequency domains in a subframe, with a number of resource elements in the two sets being equal to a number of elements of the plurality of multiplied sequences, 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, and a 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.
