Abstract: Methods for wireless communications over a wideband carrier are provided. Time-frequency resources of the wideband carrier within a transmission time interval are divided into multiple time-frequency resource blocks. Each of the time-frequency resource blocks corresponds to a group of contiguous subcarriers of the wideband carrier and orthogonal frequency division multiplexing symbols. Data streams may be scheduled to be transmitted in different time-frequency resource blocks, and may be destined for different user equipments or the same user equipment. Baseband processing operations may be performed on data streams scheduled in different time-frequency resource blocks independently from one another. Separate control channels or one common control channel may be configured for data transmissions in different time-frequency resource blocks.

Abstract: Communications in a wireless network for carrier Selection and switching are provided. A terminal in the wireless network is simultaneously receiving data on at most m carriers. A base station in the wireless network sends an activation command associated with more than m carriers to the terminal. The terminal activates the more than m carriers. Then the base station selects a first subset from the activated carriers, and sends a first monitoring command associated with the first subset via a first physical-layer signaling to the terminal. When load and/or interference situations are changed, the base station selects a second subset from the activated carriers, and sends a second monitoring command associated with the second subset via a second physical-layer signaling to the terminal, wherein the first subset is different from the second subset.

Abstract: A method for providing user equipment access to millimeter wave stations through a microwave station includes receiving an indication of millimeter wave stations operating within a microwave coverage area of a microwave station. In a microwave band, information associated with the millimeter wave stations is broadcasted to user equipment in the microwave coverage area. A request is sent to the millimeter wave stations to transmit configuration signals over a microwave band. An instruction is transmitted over the microwave band to the user equipment to perform proximity measurements of the configuration signals. According to the proximity measurements, a request is sent to a particular millimeter wave station to transmit beamforming signals over a millimeter wave band. An instruction is transmitted over the microwave band to the user equipment to perform beamforming measurements of the beamforming signals. According to the beamforming measurements, the user equipment is switched to millimeter wave operation.
