摘要： The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Next generation of wireless cellular operation is expected to be deployed in higher frequency above 6 GHz (eg. 10 GHz˜100 GHz, also called mmWave and/or cmWave) due to availability of large amount of spectrum bandwidths. The physical layer of wireless cellular system in both DL and UL operating in mmWave/cmWave would be based on new air-interface different from that of LTE-A air-interface because the radio characteristics is different for mmWave/cmWave bands. The initial deployment of mmWave/cmWave system is expected to operate as non-standalone system to provide additional radio resources to the UE which would be connected to the LTE-A cell for coverage purpose. The present disclosure covers initial access aspects of a UE on such future wireless system.

摘要： Methods and apparatuses are provided for communication between a UE and a Node B in a communication system. The UE receives a control signal including one bit of frequency hopping information, a resource allocation type, a resource allocation, and a cyclic shift for a reference signal from the Node B. It is determined that the frequency hopping information is used as a part of resource allocation information, if the resource allocation type indicates that two sets of resource blocks are allocated. The UE transmits data based on the frequency hopping information, the resource allocation type, and the resource allocation included in the control signal. Each of the resource blocks comprises one or more resource block groups, and a size of each resource block group is determined based on an uplink bandwidth.

摘要： Methods and apparatuses are provided for performing communication by a UE in a mobile communication system. A speed of the UE is measured by using an acceleration sensor in the UE. The UE determines that a change of the measured speed is detected in accordance with a predetermined criteria. The UE transmits information about the measured speed to a serving base station if the change of the measured speed is detected. Information about a target cell determined by the serving base station based on the measured speed is received from the serving base station. A handover procedure to the target cell is performed in response to receiving the information about the target cell.
