Abstract: There is described a Precision Time Protocol (“PTP”) transparent clock for inter-VLAN forwarding comprising a Layer 2 switch and a PTP module. The switch includes a first port associated with a first VLAN and a second port associated with a second VLAN. The switch detects a PTP frame at the first port and the PTP module receives the PTP frame. The switch forwards the PTP frame to the second port in response to the PTP module determining that the PTP frame is a forwardable frame. For another embodiment, the switch includes a ternary content-addressable memory (“TCAM”), and the PTP module configures the TCAM to include forwarding rules. The Layer 2 switch forwards the PTP frame to the second port in response to identifying a particular forwarding rule associated with forwarding the PTP frame.

A first device includes a baseband processor with an Orthogonal Frequency Division Multiplexing (OFDM) circuitry that uses a digital multi-carrier modulation scheme that defines a set of data subcarriers, a set of pilot subcarriers, and a direct current (DC) subcarrier to communicate data in a wireless channel between the first device and a second device.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless communications systems may employ one or more scheduling constraints to support efficient utilization of techniques for intra-device handling of overlapping scheduled uplink transmissions (e.g., intra-device dynamic resource cancelation and multiplexing) as well as inter-device handling of overlapping scheduled uplink transmissions (e.g., inter-device dynamic resource cancelation and multiplexing). Scheduling constraints may define how a device may apply intra-device and inter-device multiplexing and cancelation rules for various scenarios. For example, a device may apply intra-UE cancelation rules before inter-device cancelation rules. In some examples, later-received grants or uplink preemption indications (ULPIs) may not change a device's previously established decision to drop an uplink transmission.
