Abstract  Abstract

The invention claims effective method the method for managing multiple CCs for CA enabled mobile network. For CC enable/disable single LCID value for representing enable and disable command. providing a plurality of instruction commands for enabling and/or disabling multiple CCs. In addition to preventing CC unnecessary re-enable or disable considered for enabling/disabling explicit feedback. For scheduling mechanism provides a novel BSR process wherein all the TB in a TTI of the good prepared after only calculating a BSR. The new PHR format and a trigger. for the DL-UL link based on the DL grant or UL grant with CIF creating each link type. various link types used in different applications to improve scheduling flexibility and load balancing.

Methods to manage multiple component carriers (CCs) efficiently in a mobile network with carrier aggregation (CA) enabled are proposed. For CC activation/deactivation a single LCID value is used to represent both activation and deactivation command. A single command with multiple instructions is provided to activate and/or deactivate multiple CCs. In addition unnecessary re-activation or re-inactivation of a CC is prevented and explicit feedback for activation/deactivation is considered. For scheduling mechanism a novel buffer status reporting (BSR) procedure is provided where only one BSR is calculated after preparing all the transport blocks (TB) within one transmission time interval (TTI). Novel power headroom reporting (PHR) format and trigger are also provided. For DL-UL linking various linking types are created based on whether there is carrier indicator field (CIF) in DL grant or UL grant. The various linking types are used in different applications to improve scheduling flexibility and load balancing.
