Abstract: A service option overlay for a CDMA wireless communication in which multiple allocatable subchannels are defined on a reverse link by assigning different code phases of a given long pseudonoise (PN) code to each subchannel. The instantaneous bandwidth needs of each on-line subscriber unit are then met by dynamically allocating none, one, or multiple subchannels on an as needed basis for each network layer connection. The system efficiently provides a relatively large number of virtual physical connections between the subscriber units and the base stations on the reverse link for extended idle periods such as when computers connected to the subscriber units are powered on, but not presently actively sending or receiving data. These maintenance subchannels permit the base station and the subscriber units to remain in phase and time synchronism. This in turn allows fast acquisition of additional subchannels as needed by allocating new code phase subchannels.

Abstract: A UE system implements dynamic link adaptation by adding or changing control information to notify a receiver which timeslots and codes are currently active and which timeslots should be avoided. The UE provides synchronization such that the receiver knows which timeslots and codes the UE has used to map the coded composite transport channel onto physical channels. The UE attempts to avoid the timeslots which are experiencing transmission difficulties, while attempting to utilize the timeslots which are not experiencing transmission problems.

Abstract: A wireless handset including an antenna array. The antenna array includes an active antenna element and two passive antenna elements. The active and passive antenna elements are arranged to form a triangle with a vertex. The vertex includes a vertex angle and the active antenna element is disposed at the vertex. The vertex angle is between 90 degrees and 180 degrees.

Abstract: A method and apparatus for supporting Adaptive Modulation and Coding (AM&C) and Hybrid Automatic Repeat Request (H-ARQ) functions in a cellular system including at least one wireless transmit/receive unit (WTRU) and a Node B. A signal is received at the WTRU indicating a need for AM&C and H-ARQ control signaling. An AM&C and H-ARQ control signaling transport channel (TrCH) is dynamically allocated by informing a transport format selection process of the need for AM&C and H-ARQ control signaling. The transport format is selected for required transmission time intervals (TTIs) which assign transport format combinations (TFCs) to establish the AM&C and H-ARQ control signaling transport channel.
