Patent ID: 8265008

Claim:
A transmission resource assigning method for response signals, comprising: determining a list of mobile stations required to transmit response signals currently; determining the number of the response signals required to be transmitted by each mobile station; and assigning a frequency-domain sequence and a time-domain sequence having a length of 4 bits for each mobile station to transmit the response signals; wherein for multiple mobile stations assigned with the same frequency-domain sequence, the time-domain sequence assigned to the mobile station required to transmit multiple response signal is divided into multiple subsequences having a length of 2 bits to be used to transmit the multiple response signal of the mobile station respectively; and the divided subsequences of the time-domain sequence assigned to different mobile stations are orthogonal to each other between the different mobile stations, and wherein in the case where the mobile stations assigned with the same frequency-domain sequence comprise a first mobile station comprising one response signal group including 2 bits of response signals and a second and a third mobile stations comprising 1 bit of response signal respectively, the time-domain sequence is from a Hadamard matrix.
