According to one embodiment, a wireless communication device includes: a receiver configured to receive a plurality of first frames transmitted by spatial multiplexing; and a transmitter configured to transmit a second frame containing check results indicating whether the first frames are successfully received and first information specifying at least one communication device. The receiver is configured to receive a plurality of third frames transmitted by spatial multiplexing from a communication device having transmitted the first frame the check result of which represents failure and the communication device specified in the first information.

The embodiments provide a method implemented by a network device for transmitting link adaptation feedback in a Wireless Local Area Network (WLAN) that supports multi-user simultaneous transmission. The method generates and transmits a frame that includes one or more link adaptation feedback values associated with a wireless communications link between the network device and a second network device. In one aspect, the one or more link adaptation feedback values may include a link adaptation feedback value for an entire operation bandwidth of the wireless communications link and a link adaptation feedback value for a given subchannel within the operation bandwidth. In another aspect, link adaptation feedback values for one or more users of a multi-user simultaneous transmission are transmitted in a multi-user acknowledgment (ACK) frame. The embodiments allow for efficient link adaptation in a multi-user simultaneous transmission environment.

A WLAN device includes a processor implementing a MAC layer and a PHY layer which is coupled to a transceiver including a receive (Rx) chain and a transmit (Tx) chain that is coupled to an antenna. A preamble decode-based receive suspend algorithm has software stored in a memory that is implemented by the processor or by hardware including digital logic. The algorithm responsive to receiving a packet including a Physical Layer Convergence Protocol (PLCP) header, a MAC header, and data, is for analyzing a length field in the PLCP header to determine whether the packet is an undesignated packet and whether there is sufficient time remaining for implementing a turning off and then back on of an analog portion of the Rx chain to avoid missing a next packet. If the undesignated packet and sufficient time are present, the analog portion of the Rx chain is turned off.

In one embodiment, a method for improving content delivery for a user equipment (UE) is implemented on a computing device and includes: receiving a request from an application layer on the UE, determining whether said request is an ICN-based request using Information Centric Networking (ICN) transport protocol or an IP-based request using Internet Protocol (IP) transport protocol, and for each ICN-based request according to the determining: forwarding the ICN-based request to an ICN function on the UE, and compressing ICN headers in the ICN-based request using robust header (RoHC) compression.

Aspects of the disclosure provide an apparatus having a processing circuit and a transceiver. The processing circuit is configured to generate a frame to have an extended subtype under a control type, configure a media access control (MAC) header of the frame to indicate an extended control frame format, and configure a field of the frame to be an extended subtype field according to the extended control frame format to carry an identification for the extended subtype. The extended subtype is defined in addition to a plurality of subtypes that are identifiable using a subtype field in the frame according to a control frame format. The transceiver is configured to transmit signals to carry the frame.

A wireless communications apparatus includes first/second data source/sinks that respectively source/sink PDCP SDU and MAC PDU for transfer to/from a memory unit and hardware accelerators controlled by a control processor (CP). In response to sourcing transmit PDCP SDU for transfer to the memory unit, the CP controls the hardware accelerators to generate and write PDCP, RLC, MAC headers to the memory unit and assemble the generated headers and the transmit PDCP SDU from the memory unit into transmit MAC PDU for provision to the second data sink. In response to sourcing receive MAC PDU for transfer to the memory unit, the CP controls the hardware accelerators to decode PDCP, RLC MAC headers of the receive MAC PDU in the memory unit to determine locations of receive PDCP SDU in the memory unit and fetch the receive PDCP SDU from the determined locations for provision to the first data sink.

A system, device, and method for tracking and monitoring mobile phone usage while operating a vehicle in order to deter and prevent such usage are disclosed. The system comprises a device that engages with a vehicle and an application on a mobile phone to monitor the phone's usage in a vehicle and to prevent certain functions of the phone while the vehicle is being operated. The device may also record information about the different states of the device, such as the number of times and length of time the device is in each state, as well as the count and time that an audible and/or visual alarm is on, which data is transmitted to the mobile phone application. The device, in combination with the mobile phone application, may record information about certain behaviors the user engages in on the mobile phone while operating a vehicle.
