Patent number: 8670775Abstract: A CDMA data transmission system and method for periodically allocating channels to subscriber units, wherein prior to the beginning of any period all active subscriber units are identified that are in communication with the transmitter and for which there are data, exceeding a given minimal quantity, stored in a buffer. For each active subscriber unit one or more priority factors are calculated as a function of associated power levels; and on the basis of the priority factors, at least one channel is allocated to a corresponding active subscriber unit. The channel allocation is repeated in respect of any active subscriber units to which no channels have yet been allocated, subject to an availability of unallocated channels and subject to a limitation of maximum transmitter power.Type: GrantFiled: April 20, 2012Date of Patent: March 11, 2014Assignee: Quark Remote Research LLCInventor: Aharon Shapira

Patent number: 7403499Abstract: A cellular radio system transmits data from an IP-based network, through a base station controller (BSC) and any Base Station Transceiver (BTS) controlled by the BSC, to a plurality of active subscriber units. Instantaneous data transmission from the BTS to any active subscriber unit is at one of a plurality of given transmission rates and at a defined power level that is a product of a specific power and a multiplier, relative to a maximum total power transmittable by the corresponding BTS. A method for estimating the instantaneous specific power of transmission from the BTS to active subscriber units comprises defining in time a succession of observation windows, observing the data flowing into the BSC and addressed to each of the active subscribers and, for each subscriber, measuring the data flow during each of the observation windows, thus allowing calculation of an estimated specific power for each of the subscribers.Type: GrantFiled: December 1, 2003Date of Patent: July 22, 2008Inventor: Aharon Shapira

Publication number: 20040156387Abstract: An adaptive slot allocation system (50) is connectable to a data transmission system that transmits data from a transmitter (10) to a plurality of receivers over a common channel in successive time slots, each time slot being allocatable to one particular receiver for transmitting data thereto, there being for each receiver during each time slot, a given acceptable transmission rate (ATR), derived from a corresponding measured signal-to-noise ratio (SNR) reported by the receiver. All subscriber units the transmission queue currently holds data to it will be referred as belonging to a queue group. The adaptive slot allocation system (50) includes a queue group identifier (53), operative to identify all receivers belonging to the queue group and a rate factors calculator (54), operative to determine for each receiver of the queue group a rate factor.Type: ApplicationFiled: March 19, 2004Publication date: August 12, 2004Inventor: Aharon Shapira
