    摘要: System and method embodiments are provided for enabling flexible and reliable UE-to-UE based relay. The embodiments include using fountain codes for combining signals at a suitable network layer higher than a media access control (MAC) sub-layer and using a MAC sub-layer hybrid automatic repeat request (HARQ) transmission scheme. When a relay UE in a UE group for joint reception receives, from a network access point, a data packet intended for a destination UE in the UE group and including fountain code at the higher network layer, the relay UE sends the data packet to the destination UE and returns a HARQ ACK message at the MAC sub-layer to the access point. The destination UE then receives and decodes the data packet. Subsequently, upon receiving the entire data, the destination UE sends an ACK message at the higher network layer to the access point.

    摘要: System and method embodiments are provided for transmission and reception scheduling for wireless devices in a multi-user full duplex transmission environment. The embodiments enable interference avoidance between neighboring wireless devices. The system and method also enable channel sounding. In an embodiment, a method for scheduling transmissions in a multi-user wireless system includes determining, by a transmission point, neighboring wireless devices for each of a plurality of wireless devices located within a coverage area of the transmission point and determining, by the transmission point, a transmission schedules for respective ones of the plurality of wireless devices according to the neighboring information of the devices such that each respective wireless device is scheduled to transmit data over different time-frequency resources than those in which neighboring wireless devices of the respective wireless device are scheduled to receive data.

    摘要: An embodiment method of resource allocation for sparse code multiple access (SCMA) transmissions includes partitioning a resource block into a plurality of resource regions. The method also includes assigning the plurality of resource regions to respective device groups. The resource region assignments are then signaled to devices of the respective device groups. The method also includes receiving SCMA signals from the devices of the respective device groups. The SCMA signals from one group of the respective device groups are asynchronous with respect to the SCMA signals from another group of the respective device groups.
