  • Publication number: 20190155538
    Abstract: A method of operating a memory system, which includes a memory controller and at least one non-volatile memory, includes storing, in the memory system, temperature-dependent performance level information received from a host disposed external to the memory system, setting an operation performance level of the memory system to a first performance level, operating the memory controller and the at least one non-volatile memory device according to the first performance level, detecting an internal temperature of the memory system, and changing the operation performance level of the memory system to a second performance level that is different from the first performance level. The operation performance level is changed by the memory controller of the memory system, and changing the operation performance level is based on the temperature-dependent performance level information and the detected internal temperature.

  • Patent number: 10193614
    Abstract: A method for receiving data by a relay station (RS) in a wireless communication system includes: receiving radio resource allocation information via an R-PDCCH (R-Physical Downlink Control Channel); and receiving data from a base station (BS) via an R-PDSCH (R-Physical Downlink Shared Channel) indicated by the radio resource allocation information, wherein the radio resource allocation information includes information regarding an allocation of resource blocks in a frequency domain and information regarding an allocation of OFDM symbols in a time domain. Since the radio resource allocation information providing information regarding a time relationship between a control channel transmitted by the BS to a UE and a control channel transmitted by the RS to a UE connected to the RS is provided, the RS can reliably receive a signal transmitted from the BS in a backhaul link between the BS and the RS in a wireless communication system including the RS.
