  • Patent number: 9516626
    Abstract: Methods, systems, and devices are provided that may enable wireless communications systems that utilize flexible bandwidths to transmit at the same or similar rates as wireless communications systems that utilize normal bandwidths. Some embodiments identify a target rate for a broadcast channel of a first bandwidth carrier system and transmit broadcast information utilizing the target rate. The target rate is higher than a scaled rate that results from scaling the rate for a broadcast channel of a second bandwidth carrier system by a bandwidth scaling factor. The first and second bandwidth carrier systems may be flexible and normal bandwidth carrier systems, respectively. To compensate for the bandwidth scaling and effectively maintain the rate at which information is transmitted in normal bandwidth carrier systems, different optimized schedules for system and master information transmission, different channelization codes and channels, and/or different scaled spreading factors may be identified and utilized.

  • Patent number: 9504059
    Abstract: A device with concurrent long-term evolution (LTE) and WLAN uplink transmission includes a WLAN transceiver coupled to an LTE transceiver via an interface. The LTE transceiver includes an LTE Layer-1 module that determines whether an LTE data downlink activity is scheduled for an LTE downlink sub-frame of an LTE time frame, based on information in a first portion of the LTE downlink sub-frame. When determination is made that the LTE data downlink activity is not scheduled for the LTE downlink sub-frame, a message may be communicated through the interface to notify the WLAN transceiver that the second portion of the LTE downlink sub-frame is available for WLAN communication. The LTE time frame includes multiple LTE downlink sub-frames each including the first portion and a second portion. The first portion provides the information that indicates whether the LTE data downlink activity is scheduled for the second portion of that LTE sub-frame.

  • Patent number: 9491143
    Abstract: Methods and systems for improving accuracy, speed, and efficiency of context-aware pattern matching are provided. According to one embodiment, a packet stream is received by a first stage of a CPMP hardware accelerator of a network device. A pre-matching process is performed by the first stage to identify a candidate packet that matches a string or over-flow pattern associated with IPS or ADC rules. A candidate rule is identified based on a correlation of results of the pre-matching process. The candidate packet is tokened to produce matching tokens and corresponding locations. A full-match process is performed on the candidate packet by a second stage of the CPMP hardware accelerator to determine whether it satisfies the candidate rule by performing one or more of (i) context-aware pattern matching, (ii) context-aware string matching and (iii) regular expression matching based on contextual information, the matching tokens and the corresponding locations.
