摘要:
A method for data transmission is provided for determining movement speed and/or location of a mobile communication device; selecting, based on the movement speed and/or the location of the mobile communication device a frequency hopping mode from a plurality of frequency hopping modes to be used for data transmission to or from the mobile communication device; and transmitting the data using the selected frequency hopping mode.

A method of signalling system information and a method of receiving system information are provided. The method of signalling system information includes broadcasting a piece of system information in a radio cell, the piece of system information indicating that a first portion of a frequency spectrum, the frequency spectrum being available for the radio cell, is assigned to a first radio mode, the piece of system information further indicating that a second portion of the frequency spectrum is assigned to a second radio mode, the second radio mode being different from the first radio mode. A radio base station is configured to perform the method of signalling system information. A radio communication terminal is configured to receive the broadcasted piece of system information.

A method of cell reselection and a cellular radio terminal are provided. A method of cell reselection comprises measuring, while a mobile station is camped on a network cell, signals of neighboring network cells irrespective of a signal strength and a signal quality of the network cell, and performing a cell reselection of the mobile station if a cell reselection criterion is fulfilled according to a result of the measuring. A cellular radio terminal is configured to carry out the method of cell reselection.
摘要:
Wireless communication devices may directly communicate within groups of wireless communication devices using Layer-2 communications to implement “push-to-talk” type applications. In one implementation, a method may include generating a floor request signaling message to take control of a communication channel for a group. After transmitting data relating to the communications, a floor release signaling message may be generated and transmitted a number of times.

In an embodiment, a mobile radio communication device may be provided. The mobile radio communication device may include a first communication interface configured to communicate with another mobile radio communication device, a second communication interface configured to communicate with a mobile radio base station, and a relay quality determiner configured to determine a quality of relaying data between the other mobile radio communication device and the mobile radio base station via the first communication interface and the second communication interface.
摘要:
A method of accessing a physical random access channel, a method of signaling access information for accessing a physical random access channel, a mobile communication terminal and a base station are provided. The method of accessing a physical random access channel comprises selecting a plurality of transmission time intervals from transmission time intervals being allowed for accessing a physical random access channel, randomly selecting one transmission time interval of the plurality of transmission time intervals, and accessing the physical random access channel in the randomly selected transmission time interval. A mobile communication terminal is configured to carry out the method.
