Abstract: Methods and apparatuses are described for improving identification of reference signal transmissions at a user equipment (UE). One or more restrictions related to reference signal transmissions in one or more interfering signals can be identified. One or more reference signal transmissions received in the one or more interfering signals can then be detected based at least in part on the one or more restrictions. The one or more reference signal transmissions received in the one or more interfering signals can be processed to improve communications with a serving base station.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which mandated retransmission of data packets according to a compressed timeline provide an alternative to TTI bundling. A first data unit is transmitted in a first subframe and automatically retransmitted in one or more non-consecutive subframes before a response to a preceding transmission or retransmission of the first data unit has been processed. The retransmissions are terminated after an acknowledgement is processed. The automatic retransmissions occur periodically with a predetermined number of intervening subframes transmitted before each retransmission of the first data unit.

Abstract: Methods and apparatus are disclosed for improving blind-decoding and interference suppression associated with interference from non-serving cells in a wireless network, specifically, performing interference suppression on the non-serving cell control channel. Various aspect employ network-assisted blind-decoding of non-serving cell signals at UEs through the coordination, communication, and use of communication restriction conditions. Network aspects may restrict certain communications between eNBs and served UEs, and communicate the restrictions to non-served UE. The non-served UEs can then leverage the restrictions for more efficient blind-decoding of interfering eNB signals and interference cancellation of interfering eNB signals.

Abstract: Network identifiers used for control information are typically correlated in time. This correlation in time may be leveraged to reduce the control space searched, and thus the number of blind decodes performed by a UE during blind decoding of neighbor cell control information. An apparatus that exploits this correlation in time decodes a control channel transmitted by a neighbor cell to obtain a current network identifier used to perform an operation on the control channel transmission, compares the current network identifier with a set of network identifiers obtained from previously decoded control channels transmitted from the neighbor cell, and determines if the decoded control channel is valid based at least in part on the comparison. The set of network identifiers may be a list of network identifiers, or a range of network identifiers. The set of network identifiers may further include aggregation level information and frequency of occurrence information.
