    摘要: In an embodiment method, a central controller of a wireless system selects a common reference signal (“CRS”) pattern for muting on a first type of control channel by the central controller, wherein the first type of control channel is formed with resource elements (“REs”). The central controller identifies, for a set of user equipments (“UEs”) in a serving area of the central controller, a set of subframes including the first type of control channel, wherein the set of subframes has REs that overlap the CRS pattern for muting. The central controller mutes the overlapping REs in the first type of control channel, and frequency-division multiplexes the first type of control channel with data channels. The central controller transmits, to the set of UEs, the first type of control channel with the muted REs on the identified set of subframes.

    摘要: A system and method for mapping and decoding codewords in acknowledgement information communications are provided. A method for communications device operations includes determining a hybrid automatic repeat request (HARQ) response for each component carrier (CC) in a set of configured CCs, thereby producing a set of HARQ responses, generating an information vector from the set of HARQ responses, encoding the information vector based on a (n, k) linear block code corresponding to the set of configured CCs, and transmitting the encoded information vector. A unique set of bits selected from the information vector is assigned to represent a HARQ response for each different CC in the set of configured CCs. The (n, k) linear block code is obtained by a linear transformation of an original (n, k) linear block code, where n is a length of code words, and k is a length of information vectors.

By applying the subband coding with threshold method and differential perspective coding method, which change the image compression ratio and coding rate according to the characteristics of the image, the image transmission quality keeps unchanged. By changing the spread spectrum factor and adjusting the emission power accordingly or by applying the discontinuous emission mode without changing the spread spectrum factor, the purpose of increasing CDMA system capacity is reached.
