Device, system and selectively aborting reception of wireless communication packets


Some demonstrative embodiments include devices, systems and/or methods of selectively aborting reception of wireless communication packets. For example, a receiver may at least partially process a portion of a wireless communication packet, to determine based on the portion of the communication packet whether the packet is intended to be received by the receiver and, if the packet is not intended to be received by the receiver, to abort processing of a remainder of the communication packet by one or more components of a physical layer of the receiver.

Link adaptation method and apparatus in wireless lan system


A link adaptation method performed by a station (sta) in a wireless local area network (lan) system supporting multi-user multiple-input multiple-output (mu-mimo) is provided. The method includes: receiving a modulation and coding scheme (mcs) request, a steered sounding physical layer convergence procedure (plop) protocol data unit (ppdu) which is beam-formed to the sta, and a mimo indicator including mu-mimo-related information from an access point (ap); and transmitting feedback information including an mcs acquired from the steered sounding ppdu and the mu-mimo-related information to the ap in response to the mcs request..

Terminal device, base station device, and integrated circuit


There are provided a terminal device, a base station device, and an integrated circuit that enable a base station device and a terminal device to determine parameters related to uplink signals or uplink reference signals and to perform efficient communication. A terminal device that transmits a demodulation reference signal associated with a physical uplink shared channel to a base station device includes determining a base sequence number on the basis of a value of a parameter configured by a higher layer, determining the base sequence number on the basis of a physical layer cell identity, and generating a sequence of the demodulation reference signal on the basis of the base sequence number, wherein the base sequence number is determined on the basis of the physical layer cell identity in a case where a transmission on the physical uplink shared channel corresponding to a downlink control information format to which crc parity bits scrambled by a temporary c-rnti are attached is performed in a random access procedure..

Communication control method, data processing device, and storage medium


Communication performance can be appropriately and easily improved without changing an application on the host side when controlling communication between electronic devices. A computer that operates according to an operating system on an os kernel layer, has an application on an application layer that outputs a first unit of command data causing a connected electronic device to perform an operation, and has a communication port on a physical layer that sends data output from the application to the electronic device: receives data output from the application on the os kernel layer before the data is received by the communication port; accumulates the received data and generates a second unit of data that is larger than the first unit; and outputs the generated second unit of data to the communication port..

Terminal device, base station device, communication method, and integrated circuit


According to the present invention, there is provided a base station device, a terminal device, a communication method, an integrated circuit, and a radio communication system enabling a base station and a terminal device to decide a parameter related to a reference signal and efficiently communicate. A terminal device receives a reference signal associated with a physical downlink shared channel, the terminal device including means that receives the reference signal generated on the basis of a physical layer cell identity in a case in which a predetermined downlink control information format is used for scheduling of the physical downlink shared channel, and means that receives the reference signal generated on the basis of a parameter configured by a higher layer in a case in which a downlink control information format other than the predetermined downlink control information format is used for scheduling of the physical downlink shared channel..
