Abstract: Methods and devices for reducing traffic over a wireless link through the compression or suppression of high layer packets carrying predictable background data prior to transportation over a wireless link. The methods include intercepting application layer protocol packets carrying the predictable background data. In embodiments where the background data is periodic in nature, the high layer packets may be compressed into low-layer signaling indicators for communication over a low-layer control channel (e.g., an on off keying (OOK) channel). Alternatively, the high layer packets may be suppressed entirely (not transported over the wireless link) when a receiver side daemon is configured to autonomously replicate the periodic background nature according to a projected interval. In other embodiments, compression techniques may be used to reduce overhead attributable to non-periodic background data that is predictable in context.

Abstract: Embodiments are provided for a compress and forward relaying scheme in joint multi-cell processing. A plurality of base stations receive similar combinations of user signals from a plurality of users, compress the signals using quantization, and relay the signals over respective backhaul links to a processor in the network for decoding the signal. The processor determines suitable quantization noise levels for the backhaul links according to a weighted sum-rate maximization function for optimizing the quantization noise levels, subject to a backhaul sum capacity constraint on the backhaul links. The determined quantization noise levels are sent to the base stations, which then quantize the received combinations of user signals according to the quantization noise levels and relay the quantized signals to the processor. The quantization is according to a Wyner-Ziv coding or a single user compression algorithm that excludes statistical correlations between the user signals at the base stations.

Abstract: A grant-free transmission mode may be used to communicate small traffic transmissions to reduce overhead and latency. The grant-free transmission mode may be used in downlink and uplink data channels of a wireless network. In the downlink channel, a base station transmits packets to a group of UEs in a search space without communicating any transmission code assignments to the UEs. The UEs receive the downlink packets using blind detection. In the uplink channel, UEs transmit packets in an access space using assigned access codes which are either independently derived by the UEs or otherwise communicated by the base station using a slow-signaling channel. Hence, the grant-free transmission mode allows mobile devices to make small traffic transmissions without waiting for uplink grant requests.
Abstract translation: 可以使用免授权传输模式来传送小的业务传输以减少开销和延迟。 无授权传输模式可用于无线网络的下行链路和上行链路数据信道。 在下行链路信道中，基站向搜索空间中的一组UE发送分组，而不向UE通信任何传输码分配。 UE使用盲检测接收下行链路分组。 在上行链路信道中，UE使用分配的接入码来发送接入空间中的分组，所述分配的接入码由UE单独导出，或者由基站使用慢信令信道进行通信。 因此，免授权传输模式允许移动设备在不等待上行链路授权请求的情况下进行小的业务传输。

Abstract: 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.

Abstract: Embodiments of the invention describe a novel solution to enhance network service to devices with limited or no connectivity. Embodiments include network-aware nodes deployed by an end-user or operator which are configured by a network to achieve enhanced coverage, enhanced throughput, enhanced battery life, and mitigation of cell boundary experiences, etc. Embodiments provide these benefits to a specified or non-specified set of user equipment (e.g., neighboring user equipment). The service expansion terminal can be an available user equipment that is idle and that has been volunteered, assigned, or is a dedicated node with limited user interface and designed for carrying out enhanced coverage, enhanced throughput, enhanced battery life, and the mitigation of cell boundary experiences, etc. Embodiments may therefore provide low-cost, flexible deployment, and mobility thereby enabling boundaryless service.
