摘要： Methods, systems, and devices for wireless communications are described. A base station and a user equipment (UE) may communicate in a high reliability and low latency communications system (e.g., ultra-reliable low latency communications (URLLC)). The base station may signal a UE-specific scheduling request (SR) repetition configuration that the UE may utilize to transmit an instantaneous SR when a buffer status report (BSR) is triggered by a new data packet. The UE may repeatedly transmit the SR until a number of repetitions or a time period of repetitions is met or an uplink grant is received from the base station. The SR repetition configuration may include a number of parameters including a repetition setting, power settings, a resource allocation, and an acknowledgement/negative acknowledgment (ACK/NACK) procedure.

摘要： An electronic device includes a transmitter and processing circuitry communicatively coupled to the transmitter. The processing circuitry is configured to transmit a first signal directed to a communication node, determine unsuccessful receipt of the first signal by the communication node, and transmit a second signal to the communication node at a transmission power that is increased based on a trend of an elevation angle of the communication node with respect to the electronic device and based on the unsuccessful receipt of the first signal by the communication node.

摘要： A base station may transmit configuration parameters indicating positions, in a DCI, of a first bit of a first TPC command and a first bit of a second TPC command that are applicable, respectively, to a first cell and a second cell of a PUCCH group. The base station may receive uplink control information via a PUCCH. A transmission power of the PUCCH may be based on the first TPC command if the first cell is a cell for PUCCH transmission in a transmission timing. The transmission power of the PUCCH may be based on the second TPC command if the second cell is the cell for PUCCH transmission in the transmission timing.

摘要： Systems and methods are disclosed for triggering a long range extension mode of operation for a wireless device in a cellular communications network. In one preferred embodiment, the wireless device is a Machine Type Communication (MTC) device. In one embodiment, a node in the cellular communications network determines that the wireless device is to operate in the long range extension mode if there is difficulty in establishing communication between the wireless device and the cellular communications network. If the wireless device is to operate in the long range extension mode, the node activates one or more long range extension mechanisms with respect to the wireless device such that the wireless device operates in the long range extension mode. In this manner, the long range extension mode is selectively triggered for the wireless device.

摘要： Various methods and systems are provided for allocating time-frequency resources for downlink (DL) and uplink (UL) communications between base stations and mobile stations. Different forms of resource allocation messages including combinations of bitmaps and bitfields provide additional information about the resources and/or how they are assigned. In some implementations the resource allocation messages enable reduced overhead, which may ultimately improve transmission rates and/or the quality of transmissions.
