摘要： A subscriber station for use in a wireless network capable of communicating according to a multicarrier protocol. The subscriber station determines a total average signal level across N subbands, where each of 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 field indicating the total average signal level and a second data field indicating the first average signal level. The first data field may indicate the total average signal level as an absolute value and the second data field may indicate the first average signal level relative to the total average signal level.

摘要： 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.
