摘要： Provided are methods, corresponding apparatuses, and computer program products for performing out-of-band sensing on an unlicensed frequency band. A method comprises sending a configuration message for configuring measurement on at least one channel in a frequency band of a primary system; receiving a measurement report made based upon the configuration message; and determining the usability of the at least one channel based upon the measurement report, wherein the configuration message includes information regarding a respective predetermined threshold of energy detection or primary-system-feature detection, and the measurement report is for reception when a measured energy detection value or a measured primary-system-feature detection value of a received signal on the at least one channel is less than the respective predetermined threshold. With the claimed inventions, the spectrum efficiency would be improved and interference between a secondary system and an LTE system could be alleviated.

摘要： A method includes, in response to a determination one or more quiet periods conflict with specified hybrid automatic repeat request feedback timing, sending one or more indicators to one or more user equipment to indicate to the user equipment to shift the specified hybrid automatic repeat request feedback timing to a shifted hybrid automatic repeat request feedback timing. The method includes communicating hybrid automatic repeat request feedback based on the shifted hybrid automatic repeat request feedback timing. Another method includes receiving at a user equipment one or more indicators indicating to the user equipment to shift specified hybrid automatic repeat request feedback timing to a shifted hybrid automatic repeat request timing, and communicating hybrid automatic repeat request feedback based on the shifted hybrid automatic repeat request timing. Apparatus, computer program product, and computer programs are also disclosed.

摘要： Embodiments of the disclosure provide methods and apparatuses for scheduling radio resources in a communication system. According to the method, in response to receiving a request for accessing a target frequency band utilized by a Macro BS and a LPN from a frequency-shared system, a first notification is transmitted to the Macro BS, such that the Macro BS deactivates the target frequency band, and a second notification is transmitted to the LPN, such that the LPN extends its coverage. Then, information on the extended coverage is received from the LPN.
