摘要： Systems and methods for hybrid automatic repeat-request (HARQ) communication, comprising a transmitter employing hybrid automatic repeat-request (HARQ) and able to retransmit an incorrectly received packet without differently re-encoding data bits. The transmitter is further able to select at least one bit from any in a set to forward in at least one retransmission. The set contains any bits punctured from an original transmission corresponding to the retransmission. Other embodiments transmit, by a transmitter using hybrid automatic repeat-request (HARQ), a packet containing at least one punctured bit, select—without differently re-encoding data bits—at least one bit from any in a set to forward in at least one re-transmission of an incorrectly received packet, and retransmit the packet with at least one different punctured bit. The set contains any bits punctured from an original transmission corresponding to the re-transmission.

摘要： Systems and methods for media access control (MAC) layer bridging of a real communication device to a simulated network are described herein. Some illustrative embodiments include a communication network bridge that includes a processor that executes simulation software that implements a simulated network and further implements a simulated network interface that provides a communication path to the simulated communication network, and a real network interface that provides a communication path to a real communication network. A first media access control (MAC) layer message that conforms to a protocol associated with the real communication network is received by the real network interface from across the real communication network. The first MAC layer message is transformed by a first transformation operation into a second MAC layer message that is forwarded to a physical (PHY) layer of the simulated network interface.

摘要： Various techniques for connection setup for Bluetooth Low Energy (BLE) devices are disclosed. The various embodiments save power. In one example, an apparatus (such as a BLE slave) includes a controller configured to transmit advertising packets and, based on responses to the packets, and lack thereof, the controller estimates the length of the scan window and scan interval. In another embodiment, an apparatus such as a master device is configured to generate a scan update packet that specifies the scan window length, scan interval, and start and end times for that master. The controller is configured to transmit the packet to one or more slave devices.
