Abstract: A system implementing switching diversity in a scalable radio frequency communication system includes a primary radio frequency integrated circuit (RFIC), a first secondary RFIC, and a second secondary RFIC. The first secondary RFIC is configured to receive a radio frequency (RF) signal from a device via antenna elements based on a first beam setting, and transmit the RF signal to the primary RFIC. The primary RFIC is configured to receive the RF signal; downconvert the RF signal to an intermediate frequency (IF) signal; transmit the IF signal to a baseband processor; receive, from the baseband processor, a control signal including a second beam setting; and transmit the control signal to the second secondary RFIC. The second secondary RFIC is configured to receive the control signal from the first primary RFIC, and receive the first RF signal from the device via second antenna elements based on the second beam setting.

Abstract: A device implementing an unscheduled power save mode with peer notification may include at least one processor that may be configured to receive, from a network coordinator device, an acknowledgement of a request to enter an unscheduled power save mode. The processor may be further configured to, responsive to receipt of the acknowledgment, transmit an indication of entering the unscheduled power save mode to at least one other device of the network and then enter the unscheduled power save mode. While in the unscheduled power save mode, the processor may be configured to receive, from the network coordinator device, an acknowledgement of a request to exit the unscheduled power save mode. The processor may be further configured to exit the unscheduled power save mode responsive to the acknowledgment, and transmit an indication of exiting the unscheduled power save mode to the at least one other device of the network.

Abstract: A system of codeword puncturing for varying code rates may include at least one transmitter circuit. The at least one transmitter circuit may be configured to perform error correction coding to generate codewords at a first code rate. The at least one transmitter circuit may be further configured to puncture a number of bits from a location within each of the codewords to implement a second code rate that is greater than the first code rate. The at least one transmitter circuit may be further configured to provide the punctured codewords for transmission. The device may further include at least one receiver circuit that may be configured to receive bit sequences comprising received punctured codewords. The at least one receiver circuit may be further configured to insert bits into the bit sequences to compensate for the puncturing and perform error correction decoding on the bit sequences including the inserted bits.

Abstract: A device implementing low latency packet forwarding may include at least one processor circuit. The at least one processor circuit may be configured to receive a packet, retrieve routing information from the packet prior to performing an integrity check on the packet, and prepare to transmit the packet based at least in part on the routing information. The routing information may be in the form of, for example, a tag, a label, or a segment, and the routing information may be retrieved from at least one of a preamble, a PHY header, or a MAC header. In the case of the preamble, the information retrieved may be used to both perform channel estimation and route the packet. In multiple-input and multiple-output (MIMO) and/or channel aggregation implementations, at least a portion of the preamble of each stream (or channel) can be combined to form the routing information.
