Abstract: Methods, systems, and devices for wireless communications are described. Described techniques may include broadcasting a first Bluetooth packet over a channel bandwidth during a first set of one or more master slots of a periodic broadcast window; performing one or more received signal strength indication (RSSI) measurements during a first set of one or more slave slot of the periodic broadcast window; receiving from one or more receiving devices, based at least in part on the one or more RSSI measurements, one or more negative acknowledgement (NACK) signals corresponding to the first Bluetooth packet; and rebroadcasting, during a second set of one or more master slots of the periodic broadcast window, the first Bluetooth packet based at least in part on the one or more NACK signals.

Abstract: An apparatus comprises two or more SIM card connectors in a communication system configured to operate according to a plurality of communication protocols and coupled to at least one processor (610) for processing communication signals, a control unit (632) configured to generate a control signal to select a communication path (629-1, 629-2, 631-1, 631-2, 645-1, 647-1, 647-2) dedicated to an associated SIM card connector, and a switch (630) responsive to the control signal to switch the communication signals received from or transmitted to any one of the two or more SIM card connectors using the selected communication path. An apparatus comprises a plurality of radio frequency integrated circuit RFICs (640-1, 640-2) coupled to a plurality of RF interfaces of a digital baseband (600) of a communication apparatus, the plurality of RFICs includes a programmable state machine that executes programmed instructions to perform write to the RFICs, thereby enabling RF control.
