This invention provides a method for jointly optimizing network coding, channel coding, and signal constellations in non-coherent wireless multiple-input multiple-output (MIMO) wireless relay networks for the case when transceivers cannot obtain any knowledge of channel state information (CSI) due to high-speed mobility of the transceivers. In the relay networks, two terminal transceivers simultaneously transmit data to an intermediate relaying transceiver, which in turn broadcasts mixed data using physical-layer network coding to both terminals. The embodiments of this invention exploit different blind space-time trellis-coded modulations (ST-TCM) for each user, whose codebook is jointly generated over a Grassmannian manifold. The method is provided by exponential mapping with affine-lattice convolution for joint optimization of channel coding, modulations, and network coding. The method is designed for fast fading channels with and without interleaving. The method significantly improves performance in non-coherent bidirectional relaying MIMO networks.

Номер: US20130083830A1

Автор: Mike LOCKE

Принадлежит: Broadcom Corp

Embodiments of the present invention provide systems for incorporating bonding processors while avoiding bonding processor buffer overflow by initiating retransmission requests on all data lines whenever corrupted data is encountered on one data line. Initiating these “extra” retransmission requests equalizes retransmissions delays over all transmission lines, preventing the bonding processor from receiving excess data that cannot be reassembled until the retransmission request is processed.

Systems and methods for packet re-transmission in multi-hop wireless networks are provided. In some embodiments, RLP packet re-transmission only starts from the hop where L 1 ARQ fails. This can result in an increased efficiency of radio resource utilization, such as in implementations where the last hop is more unstable than the remaining hops. In some embodiments, a short RLP recovery delay enables a higher number of re-transmissions of lost RLP packets which, in turn, translates into a higher target physical layer FER (frame error rate) being allowed and/or an increased system capacity. Alternately or additionally, a short RLP recovery delay may reduce the possibility of TCP re-transmission and slow start.

There exists a need to reduce re-transmission delays in real time feeds (such as video) by sending the packet with sufficient repair/recovery information inside the packet container so the relaying stations and/or the receiving devices can fix errors in transmission by perusing the contents of the packet and the repair information, and modify the packet and then relay it. By providing the relaying station the ability to fix the error, retransmission of the packet is avoided along each relay station along the network path from source to destination and also by receiving devices that would otherwise request a re-transmission. This application teaches a method so real time streams (e.g. video) may be more efficiently transported over a CSMA based network.

A timer for processing data blocks is proposed for a receiver of a mobile communications system. If the timer is not running, the timer is started based a data block. The data block has a sequence number higher than a sequence number of another data block that was first expected to be received. If the timer is stopped or expires, the timer is based on a highest sequence number of a data block among data blocks that cannot be delivered to a higher entity. The timer can be used to prevent a stall condition in mobile communications.

Принадлежит: Huawei Technologies Co Ltd

The present invention discloses a method for retransmitting a data packet in a quick path interconnect system, and a node. When a first node serves as a sending end, only the first data packet detected to be faulty is retransmitted to a second node, thereby saving system resources that need to be occupied in the data packet retransmission. When the first node serves as a receiving end, it implements that the packet loss does not occur in the first node in a case that the second node only retransmits the second data packet detected to be faulty, thereby ensuring reliability of the data packet transmission based on the QPI bus.
