A method and apparatus are disclosed for enabling very high throughput (VHT) communications. A wireless transmit and receive unit (WTRU) may receive, from an access point (AP), a management frame comprising VHT capabilities information. The VHT capabilities information may comprise an indication of support for reception via non-contiguous channels. The WTRU may transmit, on a condition that reception via non-contiguous channels is supported, at least one data packet, to the AP, via multiple non-contiguous channels. The multiple non-contiguous channels may be used simultaneously.

A semiconductor integrated circuit includes a first transmission power mode configured to transmit by a first power, and a second transmission power mode configured to transmit by a second power smaller than the first power, the semiconductor integrated circuit. The semiconductor integrated circuit includes a first transistor configured to receive and amplify a transmission signal in the second transmission power mode, and an attenuator including a resistor element and a switching element, provided between an output of the first transistor and an output terminal, configured to control attenuation of an output signal of the first transistor.

Systems and methods are provided that may be implemented to optimize or otherwise control radio module transmit power performance from a given wireless-enabled information handling system platform based on a set of system-specific RF parameter values that are provisioned and stored on the information handling system platform and that uniquely represent particular RF characteristics (e.g., such as specific device environment, system chassis configuration, etc.) of the given information handling system.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may determine, based at least in part on a first model, an estimated position of the first wireless communication device. The first wireless communication device may determine, based at least in part on a second model, an estimated direction for transmission of a packet to a second wireless communication device. The first wireless communication device may determine, based at least in part on a third model, an estimated transmit power for transmission of the packet. The first wireless communication device may determine, using a neural network, a narrow beam based at least in part on the estimated position, the estimated direction, and the estimated transmit power. The first wireless communication device may transmit the packet on the narrow beam to the second wireless communication device. Numerous other aspects are provided.

A method and apparatus for signaling the release of a persistent resource in long term evolution (LTE) are disclosed. An indication of the release of a downlink (DL) persistent resource is received by a wireless transmit receive unit (WTRU) from an evolved Node-B (eNB) via a physical downlink control channel (PDCCH). A positive acknowledgement (ACK) is transmitted by the WTRU which denotes that the indication has been received. The PDCCH or a medium access control (MAC) CE may be used by the eNB to signal the indication. At least one bit may be added to contents of the PDCCH to signal whether the PDCCH is for DL persistent or dynamic resource allocation. The DL persistent resource is then released and an indication that the DL persistent resource has been released is transmitted.

A wire device receives: configuration parameters of: a primary cell with a primary physical uplink control channel (PUCCH); and a secondary cell with a secondary PUCCH; a transmit power control (TPC) radio network temporary identifier (RNTI); a primary TPC index of the primary PUCCH; and a secondary TPC index of the secondary PUCCH. The wireless device receives a downlink control information (DCI) associated with the TPC RNTI. The secondary TPC index identifies a TPC command in an array of TPC commands in the DCI. The wireless device adjusts a transmission power of the secondary PUCCH based on the TPC command.
