摘要： Apparatus and methods for interlacing communications in random access control channels of an Orthogonal Frequency Division Multiple Access (OFDMA) wireless communication system are described. A wireless communication device communicating over distinct OFDMA control channels to multiple serving sectors may operate under link limited conditions. The wireless communication device can interlace the communications between the multiple serving sectors. The wireless communication device can interlace the control channel communications in a number of interlaces equal to the number of distinct control channels over which communications are scheduled. In another embodiment, the wireless communication device divide the multiple scheduled control channel communications into two or more sets and can interlace the sets. In another embodiment, the wireless communication device can reserve a first interlace for control channel communications with the serving sector and can time multiplex the remaining control channel communications on a second interlace.

摘要： Techniques for utilizing a capacity-based effective signal-to-noise ratio (SNR) to improve wireless communication are described herein. In an embodiment, a mobile terminal can determine the effective SNR from a forward link channel using pilot/data symbols. The mobile terminal can convey the effective SNR to a base station. In order to minimize transmission overhead, the mobile terminal can quantize the effective SNR prior to transmitting it to the base station. In another embodiment, the base station can determine the effective SNR from a reverse link. The base station can utilize the effective SNR to facilitate scheduling transmissions from the mobile terminal, transmitting power control commands to the mobile terminal, and determining a supporting data rate for the mobile terminal, for example. Suitable SNRs include constrained, unconstrained, average, and/or approximated effective SNRs. In addition, various filters, such as an averaging filter, can be utilized to further process the effective SNR.

摘要： Inter-sector interference for a target user in a sector may be controlled by selectively blanking or attenuating transmit powers for interfering users in neighboring sectors whenever their transmissions collide. The sector provides the frequency hopping (FH) sequence or subband usage for the target user to the neighboring sectors. Each neighboring sector uses the target user's FH sequence to form a blanking pattern. Each neighboring sector then either blanks or reduces transmit power for each subband in its blanking pattern. Each user in each neighboring sector receives either (1) punctured symbols for subbands in the blanking pattern, if blanking is performed, or (2) lower energy symbols for these subbands, if attenuation is performed. In any case, the target user and each neighboring user may process their received symbols in the normal manner and do not need to be informed of the blanking/attenuation.

摘要： For channel estimation in a spectrally shaped wireless communication system, an initial frequency response estimate is obtained for a first set of P uniformly spaced subbands (1) based on pilot symbols received on a second set of subbands used for pilot transmission and (2) using extrapolation and/or interpolation, where P is a power of two. A channel impulse response estimate is obtained by performing a P-point IFFT on the initial frequency response estimate. A final frequency response estimate for N total subbands is derived by (1) setting low quality taps for the channel impulse response estimate to zero, (2) zero-padding the channel impulse response estimate to length N, and (3) performing an N-point FFT on the zero-padded channel impulse response estimate. The channel frequency/impulse response estimate may be filtered to obtain a higher quality channel estimate.

摘要： Techniques are provided to support fast frequency hopping with a code division multiplexed (CDM) pilot in a multi-carrier communication system (e.g., an OFDMA system). Each transmitter (e.g., each terminal) in the system transmits a wideband pilot on all subbands to allow a receiver (e.g., a base station) to estimate the entire channel response at the same time. The wideband pilot for each transmitter may be generated using direct sequence spread spectrum processing and based on a pseudo-random number (PN) code assigned to that transmitter. This allows the receiver to individually identify and recover multiple wideband pilots transmitted concurrently by multiple transmitters. For a time division multiplexed (TDM)/CDM pilot transmission scheme, each transmitter transmits the wideband pilot in bursts. For a continuous CDM pilot transmission scheme, each transmitter continuously transmits the wideband pilot, albeit at a low transmit power level. Any frequency hopping rate may be supported without impacting pilot overhead.

摘要： Techniques for selecting a reverse link (RL) serving base station for a terminal are described. The terminal sends a transmission on the reverse link to multiple base stations in a wireless communication system. The transmission may be for signaling sent on a control channel. The terminal receives feedback (e.g., power control (PC) commands and/or erasure indications) from the multiple base stations. Each base station may generate feedback based on the control channel and/or some other transmission received from the terminal. The terminal performs reverse link power control and further selects an RL serving base station based on the received feedback. For example, the terminal may select the base station with the lowest transmit power level, the largest percentage of power down commands, or the lowest erasure rate as the RL serving base station.
