Abstract: Methods, systems, and apparatus for a low-latency network interface. One of the methods includes receiving a signal having encoded data. A bit stream is generated from the received signal. Bits of the bit stream are shifted into a shift register until a feedback signal generated by a synchronization decoder is received. After the feedback signal is received, output of the shift register is descrambled to generate descrambled data. The descrambled data is stored in a first parallel register when the synchronization decoder determines that the data in the shift register is aligned to a word boundary. If the data in the first parallel register is properly aligned, the output is stored in a second parallel register.

Abstract: A technique allows stations to utilize an equal share of resources (e.g., airtime or throughput). This prevents slow stations from consuming too many resources (e.g., using up too much air time). Fairness is ensured by selective dropping after a multicast packet is converted to unicast. This prevents slow stations from using more than their share of buffer resources. Multicast conversion aware back-pressure into the network layer can be used to prevent unnecessary dropping of packets after multicast to unicast (1:n) conversion by considering duplicated transmit buffers. This technique helps achieve airtime/resource fairness among stations.

The failover linked list corresponds to a switchover rule. The mirroring rule and the switchover rule are stored in the same table. Copies of the packet are forwarded according to a multicast rule that is represented by a hierarchical linked list with N tiers.

Abstract: A user equipment (UE) receives and decodes a first erroneous transport block (TB) from a base station in a mobile communication network. The UE allocates a first soft buffer having a first buffer size. The first soft buffer is associated with a first HARQ process for storing the first TB. The UE then receives and decodes a second erroneous TB from the base station. The UE allocates a second soft buffer having a second buffer size. The second soft buffer is associated with a second HARQ process for storing the second TB. The UE releases a portion of the first soft buffer to be allocated as part of the second soft buffer. The dynamic buffer allocation method reduces mismatch between rate matching and soft buffer storing when the total number of HARQ processes is small. In addition, more HARQ processes can be supported when the corresponding TB size is small.
