    Abstract: The present invention is a user equipment (UE) which receives a communication signal over a physical reference channel using a reference channel receiver. An expected path loss is calculated using a path loss calculation device in response to the received communication signal. A signaling receiver receives an allocation of an uplink control channel including the amount of interference in the channel. Then, a power level calculation device, responsive to the path loss calculation device and the signaling receiver, determines an uplink power level based on the path loss and the interference level, whereby an uplink control channel transmission is initiated having the power level determined by the power level calculation device.

    Abstract: A method for a base station to optimize radio resource utilization and adjust data rates in a wireless digital communications system. The base station communicates with a plurality of user equipment mobile terminals (UEs) and employs adaptive modulation and coding (AM&C) to achieve improved radio resource utilization and provide optimum data rates for user services. Blocks of downlink (DL) data are received by the base station which requests downlink DL channel quality measurements only from those mobile terminals (UEs) with pending downlink transmissions. The UEs respond to the request by measuring and reporting DL channel quality to the base station, which then allocates resources such that the UEs will make best use of radio resources. The base station notifies the UEs of the physical channel allocation indicating the modulation/coding rate and allocated slots followed by transmission of blocks of downlink data which are transmitted to the UEs.

    Abstract: A data packet is provided for transmission having a first processing gain for reception at a first power level or higher. The data packet is modified prior to transmission such that the data packet has a preamble wherein data in the preamble has a second processing gain higher than the first processing gain for reception at a second power level lower than the first power level or higher. The user equipment unit transmits the modified data packet over the random access channel at a power level such that the modified data packet is initially received at the base station at at least the second power level. The transmission power level is adaptively controlled while the preamble data is transmitted such that the base station receives the data of the data packet having the first processing gain at least the first power level.

    Abstract: In telecommunications systems, a plurality of User Equipment (UEs) communicate with a common station via communication signals which have a system frame format. Commonly used time slots (CUTSs) are available for common use by the UEs for transmitting code identified signals for a specific uplink channel. The UEs select a code identifier from a plurality of identifiers, such as midambles. A UE transmission with a selected code identifier in a selected CUTS will fail if another UE transmits with the same code identifier in the same CUTS or if the UE transmission lacks sufficient power. Communication efficiency is enhanced by determining the number of successful and failed UE transmission in CUTSs per frame and adjusting one or more communication parameters in response to said determination such as a parameter upon which the UEs determine an access rate for transmitting in CUTSs and/or a power control parameter.
