Abstract
Official abstract text for this publication.
A base station configured for carrier aggregation, includes: a receiver; and processing circuitry coupled to the receiver and configured to: allocate to a user equipment uplink resources for at least one activated serving cell configured with an uplink carrier, the uplink resources for new transmission and the allocated uplink resources may accommodate a power headroom report, and obtain, responsive to the allocated uplink resources, a configured maximum output power for an activated serving cell configured with an uplink carrier, where the activated serving cell has non-adaptive retransmission of uplink data, or the activated serving cell where the base station schedules channel state information but no allocated uplink grant for transmitting data of an uplink shared channel.
First claim
Opening claim text (preview).
What is claimed is: 1. A communication system, comprising: a user equipment; and a base station which communicates with the user equipment using carrier aggregation, wherein the user equipment includes: processing circuitry configured to: when a power headroom report has been triggered, and, for a current subframe, the user equipment has uplink resources allocated for new transmission and the allocated uplink resources may accommodate the power headroom report, judge whether for the current subframe the user equipment has non-adaptive retransmission of uplink data on an activated serving cell configured with an uplink carrier; obtain, from a physical layer, a configured maximum output power corresponding to the activated serving cell if for the current subframe the user equipment has non-adaptive retransmission of uplink data on the activated serving cell; and a transmitter configured to report the obtained configured maximum output power from the physical layer to the base station, and wherein the base station includes: a receiver configured to receive the configured maximum output power transmitted from the user equipment.
