20140036849 | Joint Transmission CoMP with Single Carrier Cell Aggregation - A method, apparatus, and computer program determine each transmission point participating in a joint cooperative multi-point transmission to a UE, send a downlink message to the UE which identifies each of the transmission points, and which schedules for the UE downlink resources on which each of the transmission points are to send downlink data to the UE, and send a transmission to the UE on one of the downlink resources in conjunction with each other transmission point's transmission to the UE. A method, apparatus, and computer program receive a downlink message which identifies each of transmission points participating in a joint cooperative multi-point transmission with a UE and which schedules downlink resources on which the UE is to receive downlink data from the transmission points for the joint transmission, and receive, at the UE, a transmission on one of the downlink resources in conjunction with the other transmission point's transmission. | 02-06-2014 |
20110317657 | Change of rate matching modes in presence of channel state information reference signal transmission - In one aspect thereof the exemplary embodiments of this invention provide a method that includes, prior to confirmation that a network access node has correctly acquired capabilities of a user equipment, operating a user equipment with the network access node in accordance with a first rate matching mode and, only after confirmation to the user equipment that the network access node has correctly acquired capabilities of the user equipment, changing the rate matching mode to a second rate matching mode. In an embodiment the first rate matching mode comprises puncturing a downlink shared channel transmission with a set of resource elements, which may be at least one of reference symbols and muted resource elements, and the second rate matching mode comprises rate matching the downlink shared channel around those resource elements that are members of the set of resource elements. Also described are apparatus and computer readable storage medium storing program code that operate in accordance with the method. | 12-29-2011 |
20110223903 | Apparatus And Method For Synchronization - Embodiments provide a method and apparatus configured to measure a timing difference to at least one neighbouring base station, cell, NodeB, enhanced NodeB, relay and/or relays, evaluate or generate a time control command depending on the measured timing difference, and send the time control command to a serving base station or NodeB or eNB. | 09-15-2011 |
20100120360 | METHOD OF AND RADIO NETWORK FOR TRANSMITTING LAYERED DATA TO MULTIPLE RECEIVING STATIONS - A radio network with at least one sending station, at least one relay station and at least a first and a second receiving station transmits data organized in at least a first and a second layer, where at least the first layer is routed via a first path from the base station to the relay station to a first receiving station and at least the second layer is routed to the second receiving station via a different second path. | 05-13-2010 |
