A headset system comprising a headset and a base station. Each of said headset and base station comprises a transceiver configured to transmit radio signals between said headset and said base station according to a first wireless communication protocol, and each of said headset and base station further comprises a transceiver configured to transmit radio signals between said headset and said base station according to a second wireless communication protocol. At least one of said headset and said base station further comprises selecting means, such as a protocol selector configured to select one of said first and second wireless communication protocols for transmission of radio signals between said headset and said base station. The protocol selector is adapted to select the first wireless communication protocol for transmission of voice communication and the second wireless communication protocol for transmission of media content.

Methods and apparatus for flexible bandwidth operation in a wireless communication network are provided. A User Equipment (UE) monitors a first set of resources for a first control channel in a first bandwidth region. In response, to detecting the first control channel, the UE monitors a second set of resources in a second bandwidth region for at least one of control information or data, the second bandwidth region larger than the first bandwidth region, wherein the monitoring the second set of resources for the control information includes monitoring the second set of resources for a second control channel for receiving the control information scheduling resources for receiving the data.

A method and a device for adjusting frequencies of intercom apparatuses are provided. The method includes: detecting, at a current operating frequency of a first intercom apparatus, an unknown speech signal sent from an intercom apparatus other than the first intercom apparatus, the first intercom apparatus communicating with at least one second intercom apparatus associated with at least one second terminal; determining a target operating frequency; and sending a first adjusting instruction instructing the first intercom apparatus to adjust the current operating frequency to the target operating frequency; and sending a frequency changing message to the at least one second terminal for controlling the at least one second intercom apparatus to adjust the current operating frequency to the target operating frequency.
