摘要： Techniques for performing rank prediction in a MIMO system are described. Performance metrics for a plurality of ranks are initially determined. Each rank is indicative of a different number of data streams to send simultaneously via a MIMO channel. The performance metrics may relate to the capacity or signal quality of the MIMO channel or the throughput of data transmission sent via the MIMO channel. Adjustments are applied to the performance metrics for the ranks to obtain adjusted performance metrics. The adjustments account for system losses such as losses due to an error correction code used for data transmission, channel estimation errors at a receiver, variation in interference observed by the receiver, variability in transmit power due to power control, and/or other factors. A rank is selected for use based on the adjusted performance metrics for the ranks.

摘要： Methods are described herein for adjusting characteristics of signals used to verify or track the reliability of communication between a remote sensor and a managing device. For example, an exchange rate of signals sent between the remote sensor and managing device may be adjusted to minimize power consumption when the devices are determined to be reliably communicating. In some embodiments, apparatuses and methods herein may further be configured to inform an individual of when a remote sensor approaches a physical boundary, moves out of a communication range, is turned off, becomes damaged, or otherwise has or may become incapable of proper or reliable communication.

摘要： Disclosed are methods, wireless network nodes and terminal devices for matching an uplink coverage area and a downlink coverage area. The method may include determine an uplink coverage margin and a downlink coverage margin, calculate an uplink-downlink coverage gap based on differences of the uplink coverage margins and the downlink coverage margins, determine whether the uplink coverage area and the downlink coverage area are matched with each other, and adjust at least one of the uplink coverage area and the downlink coverage area in response to a mismatch of the uplink coverage area and the downlink coverage area. With the proposed methods, wireless network nodes and terminal devices, the uplink and downlink coverage areas could be matched, thereby diminishing the communication overhead and decreasing the delay.

摘要： A radio terminal is provided that can provide a flexible transmission power control for an SRS without restrictions due to the transmission power control of a PUSCH, for the purpose of enabling use of an SRS for various purposes in a HetNet CoMP environment. The radio terminal receives a control signal including a transmission power control command (TPC command) to be applied to an aperiodic sounding reference signal (A-SRS), through a physical downlink control channel (PDCCH), updates a transmission power value of the A-SRS using the TPC command, and transmits the A-SRS using the updated transmission power value in accordance with a transmission request included in a control signal indicating assignment of a physical downlink data channel (PDSCH) or assignment of a physical uplink data channel (PUSCH).
