Patent number: 11101920Abstract: A transmitting device performs a channel assessment in a previous sub-frame in an unlicensed carrier. After a successful channel assessment, the transmitting device starts a data transmission. The transmitting device transmits a control message for indicating the data transmission in (E)PDCCH. The control message may include the starting time of the data transmission and/or at least one transmission characteristic in the previous sub-frame. The transmission device may transmit an initial control message for indicating a potential data transmission being started in the sub-frame in which the initial control message is transmitting. Method and apparatus enable (E)CCA to take place at any time, and data transmission to start earlier than the next sub-frame boundary after a successful completion of (E)CCA, thus improving the data transmission capacity, especially in circumstances when the maximum length of transmission is constrained.Type: GrantFiled: November 7, 2014Date of Patent: August 24, 2021Assignee: ALCATEL LUCENTInventors: Matthew P.

Patent number: 11095370Abstract: A bidirectional optical repeater having two unidirectional optical amplifiers and a supervisory optical circuit connected to optically couple the corresponding two optical paths through the repeater. In an example embodiment, the supervisory optical circuit is symmetrical in the sense that it enables the two optical input/output port pairs of the repeater to be interchangeable and functionally equivalent at least with respect to two supervisory wavelengths and some in-band and/or out-of-band wavelengths. This symmetry can advantageously be used, e.g., to improve the installation process directed at installing such optical repeaters in an undersea cable system. For example, a single directional orientation of the optical repeaters does not need to be maintained throughout the cable system, which can significantly reduce the risk and/or cost of installation errors.Type: GrantFiled: February 18, 2020Date of Patent: August 17, 2021Assignee: ALCATEL SUBMARINE NETWORKSInventor: Stephane Ruggeri
