    Abstract: Several open-loop solutions encompass the small delay CDD codeword cycling and codeword cycling between different re-transmissions of both small and large delay CDD, and include an open-loop codeword cycling method for an SFBC+FSTD scheme, as well as its extension to SFBC+FSTD based HARQ. In one method, a plurality of information bits are encoded, scrambled and modulated to generate a plurality of modulation symbols. The plurality of modulation symbols are mapped onto the subcarriers in at least one transmission layer of a transmission resource. The modulation symbols are then precoded using a matrix for cyclic delay diversity and a set of codewords from a certain codebook to generate a plurality of precoded symbols. The codewords are cycled for every a certain number of subcarriers. Finally, the precoded symbols are transmitted via a plurality of transmission antennas.

    Abstract: A subscriber station for use in a wireless network capable of communicating according to a multicarrier protocol determines a total average signal level across N subbands within a channel, where each subband comprises a plurality of subcarriers. The subscriber station also determines a first average signal level within a first subband. The subscriber station then transmits a channel quality indicator (CQI) feedback message to the wireless network. The CQI feedback message comprises a first data indicating the total average signal level across the N subbands and a second data indicating the first average signal level within the one subband. The first data may indicate the total average signal level as an absolute value and the second data may indicate the first average signal level relative to the total average signal level using one of two or more unequal quantization levels.

    Abstract: Asynchronous Hybrid Automatic Repeat reQuest (ARQ) process identities are transmitted 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.
