Methods and apparatus for controlling the communications between a wireless microphone receiver and one or more wireless microphone transmitters are described. In accordance with some embodiments a common control channel is used for communicating control signals between the wireless microphone receiver and one or more wireless microphone transmitters, while separate audio data channels are used to carry audio data traffic from each individual wireless microphone transmitter to the microphone receiver. In accordance with some other embodiment, a time division approach is used in which there are microphone transmit time periods and control signaling time periods. During the microphone transmit time periods, wireless microphone transmitters transmit audio data signals and, in some embodiment, control signals, to the wireless microphone receiver using separate frequency subbands within a frequency band. During control signaling time periods, the wireless microphone receiver transmits a control signal to a wireless microphone transmitter using the frequency band.

Methods and apparatus related to timing synchronization used in a wireless microphone system to reduce and/or minimize interference are described. A wireless microphone receiver in some embodiments performs open loop timing control based on signals from an adjacent wireless microphone receiver and participates in closed loop timing control of wireless microphone transmitters which communicate with the particular wireless microphone receiver. The closed loop timing control includes instructing individual wireless microphone transmitters to advance or retard their symbol timing so that symbols transmitted by different wireless microphone transmitters are received in a synchronized manner at the wireless microphone receiver. The closed loop timing control allows a wireless microphone receiver to control wireless microphone transmitters to take into consideration their different distances to the receiver and the differing transmission times associated with the wireless microphone transmitters at different locations.

A wireless microphone receiver is used to control transmission power and/or channel configuration of wireless microphones which communicate audio data to the wireless microphone receiver. In some embodiments the wireless microphone receiver searches for available channels, e.g., on a periodic or other basis. Based on wireless microphone receiver loading and interference considerations, channel availability may be determined and channel assignments are made. In some embodiments channel assignments are made based on wireless microphone battery status. Channel assignments to wireless microphones are communicated via a control channel. In addition to channel assignments, wireless microphone transmitter power can be controlled by the wireless microphone receiver. Commands to increase or decrease transmission power may occur as channel conditions change and/or on a recurring periodic basis. The rate of power control transmission may be relatively infrequent, e.g., a second apart in some embodiments, given that wireless microphones tend to be relatively stationary during use.
