Abstract: In a multiple node network, the method includes waking up at least one node from a sleep mode during at least one associated slot of a time-slotted frame, the sleep mode being a low power consumption mode. Also, in at least one node of a multiple node network, the period of time a node sleeps is based on the residual energy of the node, the residual energy of the nodes in the neighborhood, neighborhood node density, and combinations thereof.

Abstract: In a mobile station-mobile receiver arrangement a method and apparatus for a radio link control (RLC) protocol that allows partial recovery of data for streaming services. The maximum number of retransmissions allowed by the method for each RLC block is a function of the maximum delivery delay required by the streaming service and the round trip delay.

Abstract: A method and system for reducing delay in wireless communications by use of a burst based access and assignment system. The method for setting up a communication channel uses short burst(s) (essentially a slot of a time frame). Time is saved by keeping the uplink and downlink channels flexible and independent of each other. Thus less time is used trying to fit all requests and responses into constrained choices as in previous protocols. The result is less delay to the mobile user and greater usage density for the wireless service provider.

Abstract: In a wireless communications system which hops from frequency to frequency, rather than hopping according to a fixed dwell interval and a predetermined pseudo-random hop sequence, a quality-based frequency hopping methodology is defined in which a new frequency is hopped to when the channel quality on the current frequency degrades based on the measured value or values of one or more predetermined metrics that are associated with channel quality. When triggered to hop to a next frequency, the hop-to-frequency may be the next frequency in the pseudo-random hop sequence known to both the transmitter and receiver or, in order to improve the reliability of communications, may be determined based on channel quality measurements on different potential hop-to-frequencies.

Abstract: A method for scheduling transmissions to a plurality of users in a communication network determines a satisfaction metric and a dissatisfaction metric for each user in a given timeslot that is to be used for a next scheduled transmission to one of the users. Each user is assigned a weight based on a value of at least one of the user's satisfaction metric, the user's dissatisfaction metric and a rate requested by the user. The use having the highest weight is selected to be served the next scheduled transmission in the given timeslot.

Abstract: A scheduler and a method for scheduling transmissions to a plurality of users (105) in a communication network assigns a higher target minimum throughput for receiving a next transmission to a user based on a quality of service (QoS) class of the user. A token count that tracks the user's achieved performance relative to a target minimum throughput Is determined for each user in given timeslot, and a weight is determined for each user based on one or more of the token count and a current rate requested by the user. A user having the highest weight as determined by a weight function is scheduled to be served the next transmission. User priority for scheduling may be downgraded if an average data rate requested by the user is less than the target minimum throughput.
