摘要:
A base station apparatus assigns a plurality of cells to a mobile station apparatus, and the base station apparatus and the mobile station apparatus communicate with each other via the plurality of cells. The plurality of cells are grouped into a plurality of groups, each group being made up of at least one cell having an identical transmission timing in the mobile station apparatus. In a case where a cell that has been deleted from one of the plurality of groups is added to another one of the plurality of groups in accordance with an instruction from the base station apparatus, the mobile station apparatus sets the added cell to be in a deactivated state.

According to one embodiment of the present specification, a method for reporting performance of a terminal in a mobile communication system includes the steps of: receiving a request for performance reporting from a base station; determining an indicator of whether a delay time related operation that the terminal supports is in correspondence with the request which corresponds to a pre-set condition; and transmitting a message including the determined indicator to the base station. According to one aspect of the present specification, the size of the performance reporting message is minimized in reporting the performance of the terminal.

Systems, apparatuses, and methods for uplink timing maintenance in wireless communications are provided. Certain aspects of the disclosure involve applying a timing advance command to adjust uplink transmission timing/resume uplink synchronization; and determining a metric. The metric can be used in determining whether to apply a timing advance command (TAC) to resume uplink resynchronization.

A method for multiple point communications includes configuring a set of first communications system resources to form a plurality of first communications system resource groups, each first communications system resource group including a plurality of channels, and configuring a set of second communications system resources for each one of the plurality of first communications system resource groups, the set of second communications system resources used to convey a feedback transmission. The method also includes signaling information about the plurality of first communications system resource groups to a first user equipment, and signaling information about the sets of second communications system resources associated with the plurality of first communications system resource groups to the first user equipment.
摘要:
The present invention relates to a method and apparatus for the efficient estimation of the movement state of a terminal in a mobile communication system. The method for the estimation of the movement state of a terminal in a mobile communication system according to one embodiment of the present invention comprises the following steps: receiving, from a base station, cell counting information to be used in counting for cell change; determining whether or not counting is restricted using the cell counting information during the cell change; if the counting is not restricted, counting the number of cell changes; and estimating the movement state of a terminal using the counted number of cell changes. According to the present invention, the movement state of a terminal can be efficiently estimated in a mobile communication system in which a plurality of cells having different sizes are arranged.
摘要:
The present invention proposes a method of sending a UE the timing advance information per carrier group promptly and commanding preamble transmission, and activating secondary carriers in a wireless communication system supporting carrier aggregation technology using uplink transmission timings for the respective carrier groups. Through the present invention, the UE is capable of configuring the timing advance information of the carrier group promptly and activating the secondary carrier quickly, resulting in reduction of uplink transmission delay.
