摘要： A tuneable radio and method for automatically adjusting the seek sensitivity alignment for seek operations. The radio has a radio receiver for receiving broadcast radio wave signals, and a tuner adjustable for selecting from a plurality of radio wave signal channels. A detector detects signal strength of the received radio wave signals, and a seek input allows a user to initiate a seek operation to select a signal channel having a signal strength exceeding a seek sensitivity threshold. A controller calculates an average signal value and adjusts the seek sensitivity threshold based on the average value. The controller adjusts the seek sensitivity when it is determined that the radio has travelled beyond a minimum distance.

摘要： Methods and apparatus that support controlled transmission and directional reception of RTS and/or CTS messages, are described. Controlled transmission may include transmitting a same RTS message multiple times in the same direction and/or transmitting an RTS message with a length that is multiple times longer than a standard RTS message. In an aspect, a receiver may determine spatial directions of a plurality of transmitters including a first transmitter and at least one other transmitter, and may perform a beam sweep in the determined spatial directions for receiving one or more RTS messages. A transmitter may determine that a receiver is to perform a beam sweep in K different spatial directions, and may transmit a same RTS message for a data transmission K times in the same direction or an RTS message with a length approximately K times longer than a standard RTS message, during a duration of the beam sweep.
