Abstract: Techniques are provided herein to optimize up-link transmission power from a wireless terminal to a base transceiver station in a multicarrier system. A pathloss between the wireless terminal and the base transceiver station is determined. A determination is made if the pathloss is less than or larger than a predetermined value.

A power cap command signal is sent from the base transceiver station to the wireless terminal for limiting a maximum allowable power transmitted by the wireless terminal to a predetermined level based on proximity of the one or more sub-carriers to an edge of a frequency band used for up-link transmissions made by the wireless terminal.

Abstract: Methods and apparatus for prioritizing voice call requests during data communication sessions involving a mobile communication device are disclosed. In one illustrative example, an end user invokes a voice call request though a user interface of the mobile device. If this request is made while the mobile device is engaged in a connected data communication service, the mobile device immediately forces the connected data service into a dormant state.

Subsequently, a voice call with the mobile device is established using a new traffic channel. When the voice call is completed, data communications will resume if needed. Advantageously, the mobile device prioritizes voice calls over data communication sessions which may be deemed less time-critical.

Abstract: To schedule uplink transmission time slots for a collection of mobile communication devices, a set of base station target interference patterns is associated with base stations. A time slot target interference pattern is assigned for each time slot and it repeats after several time slots. The time slot target interference pattern in a given time slot specifies the interference allowed by each time slot to a given base station by any single mobile. A priority index may be determined for each time slot for each mobile associated with the particular base station. The priority index may be based, in part, on a determined correlation between the time-slot target interference patterns and a potential interference profile of a mobile to which a time slot is to be allocated. A mobile's throughput requirement, the throughput already received over a specified past duration, the system fairness requirement, as well as the amount of data available for transmission are also used for evaluating the priority index.

Abstract: Terminals #1 to #3 which have already been connected and a terminal #4 which wants to make a new connection send packets to a base station in that order. The base station queues the packets from the terminals #1 to #3 at a non-priority queue and the packet from the terminal #4 at a priority queue. For example, a predetermined amount of packets from a new connection is queued at the priority queue. Packets in the priority queue are dequeued with priority. Therefore, the packet sent from the terminal #4 is first sent to a base-station controller, and then the packets sent from the terminals #1 to #3 are sent to the base-station controller. As a result, the base-station controller first receives the packet sent from the terminal #4, and the period of time required for the terminal #4 to establish a connection is reduced.
