    摘要: Aspects describe controlling a power level for an access terminal in a wireless communication system that utilizes multiple modulation waveforms. The power can be controlled after an Access Grant is received in response to an Access Probe until the mobile device transitions into a steady state. A reference power can be continuously monitored and a setting of a power amplifier can be modified only when the reference power changes. A digital gain of a reverse data channel can be adjusted relative to the reference power level.

    摘要: A method of facilitating a silence period in a directional communication network is provided. The method may comprise initiating, by a first apparatus, a listening period mode, wherein the listening period mode comprises ceasing at least a portion of current communication and configuring the first apparatus to receive a request to initiate a new communication, determining whether a request is received during a time period in the listening period mode, and transmitting a response if the request to initiate the new communication is received during the time period in the listening period mode.

    摘要: A method is provided for wirelessly transmitting from a transmitter to one or more receivers within a multi-user (MU) multiple-input and multiple-output (MIMO) communication system. A number of concurrent (spatial) streams are dynamically allocated in a MU-MIMO transmission to each of a plurality of served receivers to maximize total data transmitted on each transmission. Streams are allocated according to a corresponding transmission queue length for each receiver and the number of receive antennas used by each of the served receivers. A transmission timer is started upon sending the transmission. A random backoff counter is also started upon one of either: (a) expiration of the transmission timer or (b) receipt of data at a transmission queue. A new transmission is sent upon expiration of the random backoff counter if the transmission timer has expired. Otherwise, the random backoff counter is restarted one or more times until the transmission timer has expired.

    摘要: Certain aspects of the present disclosure provide techniques and apparatus for operating in a television white space (TVWS) network. One example method generally includes receiving, at an apparatus, a message with a field indicating a current version of an unused frequency spectrum map (e.g., a white space map (WSM)), the unused frequency spectrum map indicating channels usable for wireless communications; determining whether the current version of the unused frequency spectrum map is different than a previous version of the unused frequency spectrum map; and using a channel for wireless communications based on the determination. Another example method generally includes accessing a database of available channels for a current location of an apparatus via a neighboring portable or fixed enabling apparatus and enabling one or more portable dependent apparatuses for the wireless communications via one or more of the available channels.
