  • Patent number: 11792062
    Abstract: The disclosed systems and methods for wireless communication directed are towards (i) encoding data bits to be transmitted over a multiple resource unit (MRU) in a wireless local area network (WLAN), (ii) creating a group of the encoded data bits based on a predetermined criterion, (iii) parsing the encoded bits in the group based on a proportional ratio associated with the MRU, (iv) modulating the parsed encoded data bits to generate modulated encoded data symbols, (v) mapping the modulated encoded data symbols to data subcarriers to generate encoded data subcarriers, the data subcarriers being associated with respective resource units (RUs) of the MRU, (vi) duplicating the encoded data subcarriers within the respective RUs, (vii) shuffling the duplicate encoded data subcarriers across the respective RUs of the MRU, and (viii) transmitting the encoded data subcarriers, and the duplicate encoded data subcarriers over the MRU in the WLAN.

  • Patent number: 6490249
    Abstract: An adaptive method and apparatus for regulating connection admission of traffic for networks, which includes a limiter that limits a volume of traffic admitted to a network through a connection admission control (CAC) procedure; and basing the connection admission control procedure at least in part on a pure measurement CAC that is solely based on measurements of actual traffic levels on the network. The connection admission control is based both on the pure measurement-based CAC and on a pure mathematical-based CAC that is solely dependent on user-supplied traffic parameters, thereby combining both types of the CAC to form a hybrid admission criterion. Where the network offers different services, managing link resources for CAC is effected by regulating the CAC procedure based on capacities assigned to service bandwidth pools that are defined for the different services offered by the network. The CAC procedure may take place on a virtual network (VN) environment.

  • Patent number: 5412647
    Abstract: A Frame Relay network must implement a rate (bandwidth) enforcement function at the access in the network so that service subscription violation by some users will not cause performance or throughput degradation of other users' service. A novel rate enforcement technique is disclosed. The new technique makes use of a "leaky bucket" algorithm in which a portion of one "leaky bucket" is set aside for high priority frames only.
