Abstract: Through the identification of different packet-types, packets can be handled based on an assigned packet handling identifier. This identifier can, for example, enable forwarding of latency-sensitive packets without delay and allow error-sensitive packets to be stored for possible retransmission. In another embodiment, and optionally in conjunction with retransmission protocols including a packet handling identifier, a memory used for retransmission of packets can be shared with other transceiver functionality such as, coding, decoding, interleaving, deinterleaving, error correction, and the like.

Abstract: Systems and methods implementing a protocol that provides reliable transport over a point-to-point link characterized by deep and sustained fades. Such a communications link may be a free space optical channel or may be a radio frequency point-to-point channel. Data frames are processed through a circular data buffer that operates in a round robin fashion at a transmission node. The coding and forward error correction processes allow for continued operation in spite of possible signal fades due to atmospheric turbulence or other causes. At a receive node, incoming data is also saved in a circular buffer. A re-acknowledgment list is maintained at the receive node for tracking recently received and decoded data. This allows for a new acknowledgment to be sent in the event that a previously sent acknowledgment failed to reach the transmission node.

Abstract: Aspects of a method and system for determining a limited soft buffer size on transport blocks for rate matching are provided. A data stream may be processed for transmission between a base station (eNodeB) and a UE via HARQ procedures. A two-stage rate-matching algorithm may be used in the HARQ procedures. A limited virtual soft buffer size at the UE in the two-stage rate-matching algorithm may be calculated on site based on channel condition information, available channel bandwidth, number of layers in spatial multiplexing, and the capacity of the UE, respectively. The data stream may be first rate-matched to the calculated limited soft buffer size available at the UE, and forwarded for second stage rate-matching to an actual physical channel size determined by the base station. The amount of bits forwarded for second stage rate-matching may equal to the calculated limited virtual soft buffer size of the virtual soft buffer.
