—In the conventional two-way relay channel, two sources exchange information with help from a relay. We introduce a generalized two-way relay channel where each source additionally sends private information to the relay. For this channel, we consider a protocol that consists of a multiple-access (MA) phase and a broadcast (BC) phase and obtain achievable(More)
—We introduce a generalized two-way relay channel where two sources exchange information (not necessarily of the same rate) with help from a relay, and each source additionally sends private information to the relay. We consider the Gaussian setting where all point-to-point links are Gaussian channels. For this channel, we consider a two-phase protocol(More)
We introduce the multiple access relay channel with generalized feedback (MARC-GF), which is more general than the known MARC (without feedback) and MAC-GF (without relay). In the MARC-GF, two sources, assisted by a common relay, send independent messages to a destination. The sources and relay each receives some feedback that may facilitate this(More)
—Motivated by the femtocell networks where cross-tier interference management is crucial to achieve higher system throughput, we consider a basic interference model consisting of a MIMO two-way relay communication network in presence of a one-way point-to-point MIMO communication link. We propose an upper-bound on the maximum degrees of freedom of this(More)
—This work establishes diversity-multiplexing trade-off (DMT) of the four-phase decode-and-forward (DF) protocol in the half-duplex, non-separated two-way relay channel. We consider a fading channel model where the source relay links are Rayleigh distributed but the direct link between sources is left more general as Nakagami-m distributed and investigate(More)
