摘要： A method, a non-transitory computer-readable medium and an apparatus for receiving a data packet that is transmitted from a first sensor node are disclosed. For example, the method performs a channel scan of a particular burst of channel scans. When the preamble packet is detected, the method determines whether the preamble packet is addressed to the second sensor node. When the preamble packet is addressed to the second sensor node, the method sends an acknowledgement packet to the first sensor node. The method then receives the data packet that is transmitted from the first sensor node. The method then sleeps for a duration of time, when there is no packet transmission that is ongoing that is destined to the second sensor node.

摘要： Methods and apparatus for wireless communication for improving the call performance and power consumption during the connection state of a user equipment (UE). Aspects of the methods and apparatus relate to receiving a transmit power control (TPC) command from a network entity and decoding every TPC slot of the TPC command.

摘要： Adaptive layer selection by a power limited device is provided by reducing a transmit power level of a mobile device by a predefined value as a result of detecting an event associated with a change to the transmit power level. A received signal level of a signal received from a network element is measured as signal level data. The signal level data representing the received signal level is modified based on the predefined value to obtain modified signal level data representing the received signal level as modified. The modified signal level data is reported to the network element.
