Abstract: A wireless digital communication method for a plurality of user equipment mobile terminals (UEs) to communicate with a base station. Adaptive modulation and coding (AM&C) is used 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 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 user equipment transmits a signature in a selected one of a plurality of time slots of a common packet channel. The common packet channel is defined by a predetermined set of codes and has a plurality of access opportunities. Each access opportunity is defined by a time slot of the plurality of time slots and a signature. An identifier of a selected code of the predetermined set of codes is identified. The selected code is selected from a currently unused code, if available, based on a code association with the access opportunity defined by the selected signature and selected one time slot.

Abstract: A model for a wireless code division multiple access communication system is generated. A plurality of first snapshots is provided. Each first snapshot has a plurality of user equipments (UEs) and base stations. Locations of the UEs in each first snapshot vary between the first snapshots. For each first snapshot, that first snapshot is divided into an uplink and downlink snapshot. For the uplink snapshot, uplink resources are assigned to each UE and an uplink transmission power level is determined of that UE. Dropped and not admitted UEs are determined in the uplink snapshot. For the downlink snapshot, downlink resources are assigned to each UE. Dropped and not admitted UEs are determined in the downlink snapshot based on the assigned downlink resources. Statistics are gathered on a performance of the system using the determined dropped and not admitted UEs.

Abstract: A system and method for automatic gain control for a wireless transmit and receive unit in a time-slotted communications system includes initializing an automatic gain control loop, sampling a received signal, and estimating the power of the received signal. The estimated power of the received signal is compared with a reference power level and an error signal is generated based upon the difference between the estimated power and the reference power level. The error signals generated by a plurality of received signals are accumulated in an accumulator, and the value of the accumulator is looked up in a table to locate a control word for an attenuator. The control word is then passed to the attenuator to adjust the gain.

Abstract: A simulation is used to determine the effect of additional users on a communications system, such as a slotted wireless communications system. Users are sequentially added and determinations are made as to whether criteria for the additional user fall within predetermined limits. If the criteria are met, the user is accepted by the simulation and a power balancing is performed for all users. The simulation is repeated for each additional user. If the parameters are not within predetermined limits, the user is dropped. The simulation presents the system in a series of nullsnapshotsnull of communications activity.

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 correct escape mechanism is determined according to interference type. Transmission is arranged so that interference may be measured at all time slots as needed to compute a measure of variance in interference in time slots. If the variance is above a predetermined value, time division duplex escape mechanisms are employed. If the variance is below a predetermined value, appropriate escape mechanisms are employed depending on whether the escape mechanism is being implemented during an uplink or downlink. Interference causing FDD WTUs may be handed over to carrier bands to control interference experienced by TDD users.
