Abstract: To comport with specific absorption rate (SAR) requirements for a transmitting multi radio mobile device transmissions of the multiple radios may be duplexed to ensure compliance with communication regulations. Duplexing of transmissions may occur if overall transmissions exceed a particular threshold value. The duplexing may be opportunistic or deterministic.

Abstract: Systems and methodologies are described that facilitate estimating transmit covariance from evaluation of a channel (e.g., forward link channel, reverse link channel, . . . ) to be utilized in linear precoding for multiple-input multiple-output (MIMO) wireless communication systems. Predefined codebooks that include any number of precoding matrices may be modified based upon transmit covariance estimations to yield improved precoding performance. Further, channel related feedback may be generated and analyzed by utilizing the modified codebooks.

Abstract: Systems and methodologies are described that facilitate generating and/or utilizing explicit and implicit feedback related to a forward link channel for linear precoding in a time division duplex (TDD) multiple-input multiple-output (MIMO) system. Implicit feedback may be provided by estimating a reverse link channel, which may be substantially similar to at least a portion of the forward link channel (e.g., based upon reciprocity). Moreover, explicit feedback may be yielded by quantizing at least part of an estimate of the forward link channel (e.g., utilizing vector and/or scalar quantization).

Abstract: Techniques to enhance the performance in a wireless communication system using segments called subbands and using precoding are shown. According to one aspect, the bandwidth for transmission to an access terminal is constrained to a preferred bandwidth which is less than the bandwidth available for transmission to an access terminal and precoding information related to the subcarriers within the constrained bandwidth is provided to a transmitter. The precoding information related to the subcarriers within a constrained bandwidth provides feedback about the forward link channel properties relative to different subbands and may be fed back on a channel associated with the bandwidth.

Abstract: A method for enhancing performance in a wireless communication environment is disclosed. The method comprises: receiving a user preference for a transmission mode; associating the user preference with an entry or entries in a codebook, where the codebook is notified from a base station to a mobile device; and assigning the user to a transmission mode corresponding to the entry or entries. A method of determining a user's preference of a transmission mode is also disclosed. The method comprises: selecting a transmission mode or modes from a codebook to apply, where the codebook is notified from a base station to a mobile device; and transmitting an identifier of the mode or modes selected.
