Patent number: 9386543Abstract: This disclose sets forth methods and devices for calculation of uplink transmission power. An indication of a non-contiguous allocation of resource blocks for an uplink transmission is received. A first additional maximum power reduction (“A-MPR”) is determined based on a smallest contiguous allocation containing the non-contiguous allocation and an allocation correction factor. A second A-MPR is determined as a non-contiguous resource allocation A-MPR for the non-contiguous resource allocation. An uplink transmission power is calculated based on a lesser of the first A-MPR and the second A-MPR. The uplink transmission is performed based on the uplink transmission power.Type: GrantFiled: April 21, 2014Date of Patent: July 5, 2016Assignee: Google Technology Holdings LLCInventors: Jean-Aicard Fabien, Colin D.

Patent number: 7321570Abstract: A communication system is provided that dynamically allocates power to a Multimedia Broadcast/Multicast Service (an MBMS service). In response to determining to establish a Point-to-Multipoint (PTM) communication channel to multiple user equipment (UEs), the communication service assigns the PTM communication channel to the MBMS service, determines a power requirement associated with each user equipment (UE) of the multiple UEs based on a handover quality measurement associated with the UE to produce multiple power requirements, and allocates a power level to the PTM communication channel based on the multiple power requirements. The communication system further dynamically adjusts the allocated power based on a handover quality measurement associated with a UE of the multiple UEs that is received during provision of the MBMS service.Type: GrantFiled: February 3, 2004Date of Patent: January 22, 2008Assignee: Motorola, Inc.Inventors: Rapeepat Ratasuk, Jean-Aicard Fabien, Amitava Ghosh, Weimin Xiao

Patent number: 7085575Abstract: In a mobile telecommunication system (10), a number of user equipments (40–45) may receive multimedia broadcast multicast services. The method for power allocation and user assignment for MBMS services determines any number (K) of user equipments which may be served without complete cell area coverage (78). For more than K user equipments (40–45) requesting MBMS services, dedicated channels are assigned (84). For user equipments requesting MBMS service during a broadcast, such user equipment is assigned to the channel (broadcast or dedicated) with the lower power requirement, if power is available. If the user is assigned to the broadcast channel, and power is available, power of the broadcast channel is adjusted (108). Otherwise, the power of the broadcast channel is increased and no further power is indicated as being available (112).Type: GrantFiled: August 18, 2003Date of Patent: August 1, 2006Assignee: Motorola, Inc.Inventors: Jean-Aicard Fabien, Amitava Ghosh, Rapeepat Ratasuk

A communication indicator (300) that is compatible with UMTS protocols and includes, in addition to paging indicators, one or more broadcast category indicator codes (304) is provided. Devices receiving the communication indicator (300) are able to ascertain based on the broadcast category indicator codes (304) whether there is a need to expend further power in determined whether they are subscribed to the broadcast.Type: GrantFiled: October 3, 2003Date of Patent: April 11, 2006Assignee: Motorola, Inc.Inventors: Jean-Aicard Fabien, Richard C.

Publication number: 20050043035Abstract: A communication system conveys Multimedia Broadcast Multicast Service (MBMS) data to multiple mobile stations (MSs) subscribing to an MBMS service while minimizing possible congestion over an Iub interface. A network controller receives at least one MBMS data packet comprising an MBMS payload. In response to receiving the at least one data packet, the network controller establishes communication channels to the multiple MSs for conveyance of MBMS data and conveys to a downstream network element, via an Iub interface, a single copy of the payload. The downstream network element replicates the received payload to produce a copy of the payload for each established communication channel. The downstream network element then assembles, in association with each established communication channel, a set of one or more data packets for conveyance via the established communication channel, wherein each set of data packets includes a copy of the payload.Type: ApplicationFiled: August 9, 2004Publication date: February 24, 2005Inventors: Michael Diesen, Zhijun Cai, Jean-Aicard Fabien
