    Abstract: A method and apparatus in a user equipment transmit a subframe shared by multiple users through a dual-antenna transmission scheme by using space-time coding. A first and a second plurality of modulation symbols are generated. A third and a fourth plurality of modulation symbols are generated by performing Alamouti coding on each pair of modulation symbols in each of the first and second pluralities of modulation symbols. A spread matrix is generated for each modulation symbol such that the first and third pluralities of modulation symbols are mapped to a first slot of the subframe, and the second and third pluralities of modulation symbols are mapped to a second slot of the subframe. The subframe is transmitted such that the first and second pluralities of modulation symbols are transmitted via a first antenna, and the third and fourth pluralities of modulation symbols are transmitted via a second antenna.

    Abstract: A method for transmission, by dividing a transmission resource in a time domain subframe into a plurality of equal duration resource elements in a time and frequency domain, segregating the plurality of resource elements into a plurality of resource regions, modulating information to be transmitted to generate a sequence of modulation symbols at a transmitter, mapping the sequence of modulation symbols into the plurality of resource elements in the plurality of resource regions, and transmitting the modulation symbols via a plurality of antennas using the respective corresponding resource elements to a receiver. The mapping of the modulation symbols in at least one resource region is independent of a certain control channel information that is carried in said time domain subframe, and the mapping of the modulation symbols in at least another resource region is dependent upon said certain control channel information that is carried in said subframe. The information to be transmitted may be encoded to generate a plurality of code blocks, with roughly equal number of resource elements assigned to each of the plurality of code blocks in at least one resource region. Alternatively, the time domain subframe may contain only one resource region.

    Abstract: Methods and apparatus for transmitting Asynchronous Hybrid Automatic Repeat reQuest (ARQ) process identities in a wireless communication system. A linking scheme is established between at least two sets of process identities of two respective corresponding codewords. When a first process identity is selected from among a first set of process identities of a first codeword, a second process identity may be derived in dependence upon the first process identity and the established linking scheme. Finally, a first packet from the first codeword is transmitted using a first transmission channel indicated by the first process identity, and a second packet is transmitted from the second codeword using a second transmission channel indicated by the second process identity. In addition, a control message including only the first process identity is transmitted.
