Abstract: Apparatus, and an associated method, for facilitating closed-loop power control in a radio communication system, such as upon reverse links defined in a CDMA2000, cellular communication system. Rate indications are modulated by a modulator upon a control channel carrier signal to form a modulated data segment. Then, the modulated data segment is repeated a selected number of times to form a concatenated sequence of modulated data segments. The modulated data segments are of sub-frame lengths and the concatenated sequences of a frame length. When the concatenated sequence is communicated and delivered to a communication station, the information contained in a sub-frame portion can be used to improve power control operations upon the reception of the sub-frame rather than waiting for an entire frame of information to be delivered to the communication station.

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.

During the modulating of the data, the data may be configured in such a way as to convey the configuration of the antennas through the modulation of the data. An antenna configuration is obtained by obtaining a representation of the antenna configuration, and masking the data with an error correcting code, where the mask corresponds to the antenna configuration.

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.
