    Abstract: Disclosed is a method and apparatus to detect an intended packet by a sliding intermediate frequency (SIF) coherent ultra low power (ULP) wireless receiver. The method includes detecting a transition from a noise period to a signal period in a pair of input sequences received, dynamically adjusting a gain of the pair of input sequences in response to the signal period being initiated, distinguishing an intended packet from packets received in preambles included in the pair of input sequences, and compensating for a carrier frequency offset of the intended packet in the signal period.

    Abstract: A method and apparatus for a collision-free carrier sense multiple access (CSMA) are provided. The method of a node associated with a beacon enabled carrier sense multiple access (CSMA)-based wireless communication network through an access point (AP) includes receiving a beacon from the AP, the beacon comprising a back-off prime number and a beacon random number, and generating a back-off interval based on the beacon random number, the back-off prime number, a mapped identification (ID) of the node, and a current time slot of a frame of the beacon. The method and apparatus provide a collision-free CSMA scheme for a beacon enabled CSMA-based wireless communication network. In the collision-free CSMA scheme, uniformly distributed back-off intervals may be generated in a distributed fashion at each node for a CSMA-based wireless communication network. The back-off intervals may be correlated among the nodes even though the nodes do not communicate with each other.

    Abstract: A system and/or method for determining an Angle of Arrival (AoA) of a signal by a base station. The technique may include configuring different time intervals and multiple phase shifts across an antenna array of the base station. The technique may include receiving the signal from UEs at the different time intervals and the multiple phase shifts across the antenna array. The technique may include estimating phase angles of the signal received at the different time intervals and the multiple phase shifts. The technique may include determining the AoA of the signal received from the UEs based on the phase angles of the signal received at the different time intervals and the multiple phase shifts.
