Abstract
Methods, systems, and devices for enhanced carrier aggregation techniques described. For example, component carrier groups including multiple component carriers may be configured. In some cases, each component carrier group may be configured to include 2n component carriers. Also, component carriers may be managed on a per component carrier group basis. In some cases, a single management message may be used to communicate management information for a component carrier group. Similarly, a single control message may be used to communicate control information, such as physical layer parameters, for a component carrier group.

A method for wireless communication at a user equipment (UE), comprising:
- receiving, from a base station, an activation message indicating an activation of a first component carrier group for carrier aggregation communications between the UE and the base station, the first component carrier group comprising a first plurality of component carriers;
- receiving, from the base station, a first set of physical layer parameters for the first component carrier group, the first set of physical layer parameters applicable to each of the first plurality of component carriers in the first component carrier group;
- and
- communicating with the base station over the first plurality of component carriers according to the first set of physical layer parameters.
A method for wireless communication at a base station, comprising:
- transmitting, to a user equipment (UE), an activation message indicating an activation of a first component carrier group for carrier aggregation communications between the UE and the base station;
- transmitting, to the UE, a first set of physical layer parameters for the first component carrier group, the first set of physical layer parameters applicable to each of the first plurality of component carriers in the first component carrier group;
- and
- communicating with the UE over the first plurality of component carriers according to the first set of physical layer parameters.
An apparatus for wireless communication at a user equipment (UE), comprising:
- a processor,
- memory in electronic communication with the processor;
- and
- instructions stored in the memory and executable by the processor to cause the apparatus to:
- receive, from a base station, an activation message indicating an activation of a first component carrier group for carrier aggregation communications between the UE and the base station, the first component carrier group comprising a first plurality of component carriers;
- receive, from the base station, a first set of physical layer parameters for the first component carrier group, the first set of physical layer parameters applicable to each of the first plurality of component carriers in the first component carrier group;
- and
- communicate with the base station over the first plurality of component carriers according to the first set of physical layer parameters.
