Single codeword, multi-layer serial interference cancellation (SIC) for spatial multiplexing

Aspects of the subject disclosure can include, for example, associating a first logical codeword with HARQ identifier, wherein the first logical codeword is based on a first plurality of channel-encoded codewords of a first plurality of transport blocks. The first logical codeword is associated with multiple layers of a MIMO system to obtain a logical codeword mapping. In response to detecting an error in one of the channel-encoded codewords, a modified first logical codeword is generated based on the one channel-encoded codeword and mapped to the number of layers of the MIMO s system for transmission to the receiver for further processing associated with the HARQ identifier. Other embodiments are disclosed.

A system for providing full-duplex communications comprises a first transceiver for simultaneously transmitting first signals having a first orthogonal function applied thereto on a first channel and simultaneously receiving second signals having a second orthogonal function applied thereto at a same time. A second transceiver simultaneously receives the first signals having the first orthogonal function applied thereto on the first channel and simultaneously transmits the second signals having the second orthogonal function applied thereto at the same time. Application of the first orthogonal function to the first signals and application of the second orthogonal function to the second signals prevents interference between the first signals and the second signals.

Network signaling for network-assisted interference cancellation and suppression

Embodiments of the invention are directed to a cellular communication network that can determine whether communications between one base station-UE pair may interfere with another UE that is in the same cell or a different cell. The network identifies interference parameters associated with interference signals that may be received by a UE. The interference signals may be generated by the base station itself, such as communications with other UEs, or by a neighboring base station. The base station transmits the interference parameters to the UE. The UE receives the one or more parameters comprising information about signals expected to cause intra-cell or inter-cell interference. The UE then processes received signals using the one or more parameters to suppress the intra-cell or inter-cell interference.
