摘要： A wireless communication system includes an infrastructure device for transmitting and receiving communications to and from a plurality of user terminals. Each user terminal includes a receiver and a controller that receives a first orthogonal frequency division multiplexing (OFDM) signal on a first carrier frequency that has assignment information indicating a second carrier frequency to transmit uplink data and beam forming information. In response to the assignment information, a transmitter of the user terminal transmits a second OFDM signal on the second carrier frequency using a beam indicated in the beam forming information.

摘要： A temporary (temp) dedicated channel (DCH) is used to support communications. The temp-DCH channel is a channel that is assigned to a user having a set duration. After the duration expires, the channel is automatically released to the user. Embodiments of the invention relate to establishing the temp-DCH channel, determining the data rate and duration of the channel. Other embodiments relate to establishing back-to-back temp-DCH channels and the implementation details of these embodiments. Additionally, one embodiment relates to adding a start/stop function to the medium access controller which can be used in conjunction with temp-DCH as well as other applications.

摘要： A wireless network provides controlled wireless communications with multi-mode wireless WTRUs. The wireless network has at least one base station having a transceiver operating in an infrastructure communication mode with multi mode WTRUs and a controller that transmits control signals via infrastructure communications with a WTRU that control peer-to-peer mode communications of that WTRU with other WTRUs. A WTRU has transceiver components configured for selective operation in an infrastructure communication mode with a network base station and in a peer-to-peer communication mode with other WTRUs. The WTRU also has a transceiver controller configured to selectively control peer-to-peer mode communications with other WTRUs based on communication signals received in infrastructure communications with a network base station. Preferably, the transceiver controller is configured to control the transceiver components to switch between infrastructure communication mode and peer-to-peer communication mode based on Quality of Service criteria.
