Abstract: A method of user equipment (UE) in a wireless communication system. The method comprises receiving, from a base station (BS), a downlink signal including position information for orthogonal frequency division multiplexing (OFDM) symbols of a short physical uplink control channel (PUCCH), determining, based on the position information, a position of the OFDM symbols of the short PUCCH included in a slot, and transmitting, to the BS, the short PUCCH using the OFDM symbols based on the determined position.

Abstract: A method comprises sniffing an input from a client device to a host device and an output from the host device to the client device; recording a first time parameter in response to a characteristic data unit being inserted into the input that is outputted from a host stack of a host device; recording a second time parameter in response to the output that comprises the characteristic data unit being received by the host stack; and measuring a latency based on the first time parameter, the second time parameter and arrival time of the input and the output at a sniffing point.

Abstract: Machine-readable media, methods, and apparatus are described. In some embodiments, a header policy for a packet to be transmitted through the network is defined based upon characteristics of the network and a header of the packet is compressed based upon whether the header policy indicates the header of the packet is to be compressed.

Abstract: According to one embodiment of the invention, a method for receiving in a signal processing subsystem a first signal comprising a predetermined pattern and a second signal comprising the predetermined pattern, and determining by the signal processing subsystem a transmission latency between the received first signal and the received second signal based on the predetermined pattern. According to another embodiment a system comprising a pattern insertion subsystem to insert a predetermined pattern into a first signal and a second signal, and a signal processing subsystem to (i) receive the inserted first signal and the inserted second signal, and (ii) determine a transmission latency between the received signals based on the predetermined pattern.
