Patent number: 8532689Abstract: The present invention relates to a cellular communication and addresses the problem of an LTE UE measuring downlink quality when the load in cell varies instantaneously and over a wide frequency spectrum. The UE lacks capacity to measure over frequency bandwidth and time needed to make a cell load measure with sufficient reliability for making a inter-cell handover or an inter RAT handover. The solution is the DL power transmitted in a narrow band of the carrier frequency is adjusted to reflect the total cell load. The total cell load is measured and averaged over time and made proportional to the frequency carrier bandwidth. The power may be controlled for specific time slots in the narrow frequency band for the terminal to measure on. This is advantageous because then the waste power needed for enabling the UE measured can be reduced and the extra interference caused by the invention be reduced.Type: GrantFiled: October 31, 2008Date of Patent: September 10, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventor: Walter Muller

Patent number: 8532025Abstract: Certain embodiments of the present disclosure may allow WiMAX signaling overhead to be reduced by sending burst allocation information to MSs using messages that may be transmitted using more efficient modulation coding schemes (MCSs) than that allowed for DL-MAP and UL-MAP messages. For example, burst allocation information may be sent in SUB-DL-UL-MAP or HARQ-MAP messages that may be encoded with selectable MCSs that result in higher data rate than an MCS used for conventional DL-MAP and UL-MAP messages. For certain embodiments, MSs may be partitioned into groups based on CINR and the burst allocation information for each group may be transmitted using an MCS that is appropriate for that group based on the CINR for MSs in that group.Type: GrantFiled: June 19, 2008Date of Patent: September 10, 2013Assignee: QUALCOMM IncorporatedInventors: Tom Chin, Kuo-Chun Lee

Patent number: 8532682Abstract: A radio access network (11) facilitates transmission of a Multimedia Broadcast/Multicast Service to plural user equipment units served by a radio base station. A radio network controller node (26) includes in a first message (70) of a Common Transport Channel Setup procedure an indication that sharing of a common transport bearer (60) involved in a session of the Multimedia Broadcast/Multicast Service is allowed. A radio base station (28) makes a determination whether to share the common transport bearer (60) among user equipment units (30) situated in plural cells (C) served by the radio base station (28). If the determination is positive, the radio base station (28) includes in a second message (80) of the Common Transport Channel Setup procedure an identification of an already-established channel to be used as the shared common transport bearer.Type: GrantFiled: April 15, 2011Date of Patent: September 10, 2013Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Sharokh Amirijoo, Tarmo Kuningas

Patent number: 8526351Abstract: Channel characterization and training within multiple user, multiple access, and/or MIMO wireless communications. Within such communication systems, there can be a number of devices (e.g., STAs) that communicate with a single device (e.g., AP). A multi-cast sounding frame may be transmitted from a transmitting device to a number of receiving devices. Appropriate scheduling or ordering of feedback signals from some or all of the receiving devices may be performed explicitly (e.g., sounding frame sent from the transmitting device to a receiving device) or implicitly (e.g., control information sent from the transmitting device to the receiving device, sounding frame sent to the transmitting device from the receiving device). Such characterization and training is with respect to a channel or path in which data will subsequently follow. Such characterization and training can be performed in accordance with group membership (e.g., with respect to only some of the receiving devices).Type: GrantFiled: June 8, 2010Date of Patent: September 3, 2013Assignee: Broadcom CorporationInventors: Matthew James Fischer, Joonsuk Kim, Peiman Amini, Joseph Paul Lauer, Vinko Erceg

Patent number: 8526981Abstract: A method for delivering a short message service (SMS) message to an interworking wireless local area network user equipment (UE) begins by registering the UE with an Internet Protocol short message gateway (IP-SM-GW). A capability report is sent from the UE to the IP-SM-GW, the capability report including the capabilities of the UE. A SMS message is transmitted from a short message service center (SMSC) to the IP-SM-GW. The capabilities of the UE are evaluated at the IP-SM-GW to determine whether the UE can receive the SMS message, and the SMS message is delivered to the UE via the IP-SM-GW if the UE has the capabilities to receive the SMS message.Type: GrantFiled: May 3, 2012Date of Patent: September 3, 2013Assignee: InterDigital Technology CorporationInventor: Kamel M.
