The present invention relates to a data transmission device and reception device in a wireless AV system. The present specification discloses a wireless data reception device comprising: a communication unit configured to receive data relating to an image from a wireless data transmission device via a wireless channel; a display unit for outputting the image; a processor configured to execute a standby mode in which a wireless data reception device or the wireless data transmission device is deactivated, and a connection reestablishment mode in which, when the wireless data reception device and the wireless data transmission device are activated, a connection setup relating to the wireless data transmission device is performed; and a memory connected to the processor and configured to store data relating to the image according to a command of the processor.

Data transmission device and reception device in wireless AV system

A method and apparatus for determining a positioning measurement interval in a wireless communication system are disclosed. The method includes acquiring a message including Observed Time Difference of Arrival (OTDOA) related data in a higher layer, wherein the OTDOA related data includes a plurality of cell identifiers and Positioning Reference Signal (PRS) configuration information of corresponding cells, transmitting the ODTOA related data to a physical layer from the higher layer, and determining the RSTD measurement interval by the following Equation by using a plurality of cell-specific PRS periods obtained using the PRS configuration information in the physical layer: T=T&#xb7;(M&#x2212;1)+&#x394; where Tdenotes the length of the RSTD measurement interval, Tdenotes the largest of the plurality of cell-specific PRS periods, M denotes the number of PRS positioning occasions, and &#x394; denotes a measurement time for one PRS positioning occasion.
