Publication number: 20140376460Abstract: A method provides information to a UE specifying a UL-DL configuration to be applied to the UE. The information is indicative of: (a) a signaling time at which a UL-DL configuration signaling for a new UL-DL configuration is to take place, and (b) an application time at which the new UL-DL configuration is to be applied. This method complements UL-DL configuration signaling by providing more reliable reception of UL-DL configuration information. This indication is performed with smaller signaling overhead compared to conventional schemes and with reasonable complexity on both the UE side and an eNB side.Type: ApplicationFiled: June 17, 2014Publication date: December 25, 2014Inventors: Kari J.

Publication number: 20130196700Abstract: A first user equipment UE operating in a first/strong transmission mode determines that a second UE is operating in a second/weak mode and is allocated a same radio resource as the first UE. The first UE determines a transport format for transmissions to the second UE and uses that to decode and cancel a transmission received on the radio resource which is directed to the second UE, mitigating interference with a further transmission directed to the first UE. Various examples are given of specific resource allocation signaling used to determine that the second UE is operating in the second mode and is allocated the same radio resource, such as implicitly by a specific downlink control indication format or an explicit indication in a resource allocation directed to the first UE. The first UE can determine the transport format of the second UE from network signaling.Type: ApplicationFiled: January 30, 2012Publication date: August 1, 2013Inventors: Esa T. Tiirola, Kari P.
