PROBLEM TO BE SOLVED: To control reverse link interference among access terminals that are power-controlled by the sector of a base station, in a wireless communication system. SOLUTION: When the maximum effective noise power spectral density is higher than a predetermined threshold, the maximum effective noise power spectral density is used as a parameter for controlling the level of reverse link loading, by setting a reverse activity bit (RAB) so as to inform access terminals to reduce their data rates, in order to minimize the interferences among these access terminals.

Abstract:
PROBLEM TO BE SOLVED: To provide techniques for managing communications in a cellular network.SOLUTION: The cellular network can include one or more sectors in which hotspot carriers are deployed. The hotspot carriers can be available to mobile devices beyond sector boundaries defined by the signal strength of ubiquitous carriers. A mobile device can measure a signal strength of a candidate hotspot carrier and estimate a reverse link mobile device transmit power level for communicating on the hotspot carrier. The mobile device determines whether to add, remove, or maintain the hotspot carrier in its active set on the basis of the estimated transmit power so as to limit interference to the reverse link of non-hotspot sectors.

Abstract:
PROBLEM TO BE SOLVED: To provide a system and method for decreasing delays and thereby improving performance of data transmission by enabling an increased data transmission rate to be selected for a reverse link between an access terminal and an access network. SOLUTION: A new data rate is selected from several limiting data rates (including a data justified rate and a ramp-up-limited rate). In one embodiment, the data-justified rate is constrained to decrease in a controlled manner and cannot suddenly drop to zero. In another embodiment, the ramp-up-limited rate is allowed to return quickly to a sticky rate when the system is not busy rather than having to ramp up to the sticky rate according to the standard probabilities.

Abstract:
PROBLEM TO BE SOLVED: To increase the throughput in a sector.SOLUTION: Upon successful decoding of a first set of slots of a first data packet, an access network (AN) can send an acknowledge message (ACK) to an access terminal (AT) to indicate that the AN has successfully decoded the data received in the first set of slots of the first data packet. Upon unsuccessful decoding of the first set of slots of the first data packet, the AN can send a negative acknowledge message (NAK) to the AT to indicate that the AN has not successfully decoded the data received in the first set of slots of the first data packet. Based upon receipt of the NAK, the AT can resend the data by sending a second set of slots of the first data packet containing redundant data. Based upon receipt of the ACK, the AT can send a first set of slots of another packet.

Abstract:
Some implementations provide a method for prioritizing reverse link packets so that particular reverse link packets are transmitted with a reduced latency in order to improve spectral efficiency of the forward link. The method also optionally includes weighting packets according to their determined lengths and transmitting packets based on the determined weights. In one implementation the method includes sorting packets at least according to one of size type and nature of the data in the packets. Accordingly sorting of the packets includes at least one of determining the size and the type of each packet. In one implementation sorting the packets includes deep packet inspection to determine a respective priority value for each packet.
