摘要： An apparatus and method estimate a high speed frequency offset in a wireless communication system. The apparatus includes a correlator, an accumulator, a phase calculator, and a frequency offset coupler. The correlator performs a first correlation and a second correlation based on a first reference signal and a second reference signal. The accumulator accumulates results of the correlations. The phase calculator calculates a first phase and a second phase from the accumulated first correlation value and the accumulated second correlation value. The frequency offset coupler determines whether a frequency offset deviates from a frequency offset estimate range based on a difference between the first phase and the second phase, and compensates the frequency offset according to the determination result. The apparatus can estimate a frequency offset within an error allowable range under an environment where a terminal moves at high speed.

摘要： An apparatus and method for encoding/decoding a transport format combination indicator (TFCI) in a CDMA mobile communication system. In the TFCI encoding apparatus, a one-bit generator generates a sequence having the same symbols. A basis orthogonal sequence generator generates a plurality of basis orthogonal sequences. A basis mask sequence generator generates a plurality of basis mask sequences. An operation unit receives TFCI bits that are divided into a first information part representing biorthogonal sequence conversion, a second information part representing orthogonal sequence conversion, and a third information part representing mask sequence conversion and combines an orthogonal sequence selected from the basis orthogonal sequence based on the second information, a biorthogonal sequence obtained by combining the selected orthogonal sequence with the same symbols selected based on the first information part, and a mask sequence selected based on the biorthogonal sequence and the third information part, thereby generating a TFCI sequence.

摘要： A resource allocation for reducing overhead in a mobile communication system is provided. An operating method of a base station for changing a fixed resource allocation to reduce overhead in a mobile communication system includes calculating a total amount of resources allocated to a corresponding subframe in a period of a corresponding fixed allocation resource; when the total amount of the resources allocated to the corresponding subframe is greater than a threshold, temporarily canceling one or more corresponding fixed allocation resources to make the total amount of the resources allocated to the corresponding subframe less than or equal to the threshold; and reallocating the one or more canceled fixed allocation resources according to a corresponding rule.

摘要： A method of adapting a mobile telecommunication system to channel conditions. To control transmission of a data packet from an access network (AN) in both a link adaptation scheme and an ARQ (Automatic Repeat reQuest) scheme, an access terminal (AT) compares the received power of a forward pilot signal received from the AN with a predetermined first threshold, checks errors in the data packet of a received time slot if the reception power is greater than the first threshold, and transmits a signal requesting termination of retransmission of the data packet to the AN if no errors are found in the data packet after decoding.

摘要： There is provided an encoding apparatus and method in a CDMA communication system. To encode input information of a k-bit sequence and generate a codeword with length N>(2k−1), an encoder encodes the input information using an (r, k) simplex code and generates a sequence of code symbols of length r (r=2k−1), a repeater repeats the sequence of code symbols t times ( t = ⌊ N r ⌋ + 1 ) , and a puncturer performs puncturing A times (A=rt−N) on the t repeated code symbol sequences so that the resulting codes have length N. The punctured symbols are distributed uniformly across the repeated code symbol sequences or confined to the tth repeated code symbol sequence.
