Abstract
The invention relates to a method for transmitting power headroom information from a user equipment to the base station. The transmission is made dependent on scheduling type of the uplink resource, for which the power headroom information is to be calculated and over which it is to be transmitted. If the uplink resource is dynamically scheduled, then the extended power headroom report according to Rel. 10 is transmitted; if it is scheduled persistently, e.g. as part of a semi-persistent scheduling configuration, then a basic power headroom report according to Rel. 8/9 is transmitted. The invention circumvents the problem of delaying data in persistently allocated uplink resources when transmitting an extended power headroom report.

24. A method for transmitting power headroom information from a user equipment to a base station in an uplink resource, wherein the power headroom information is either a basic power headroom report or an extended power headroom report, and the user equipment is configured to report the power headroom information with extended power headroom reports, the method comprising the steps of:
-
in case the uplink resource is scheduled via a persistent scheduling configuration, transmitting a basic power headroom report as power headroom information to the base station in the uplink resource, and in case the uplink resource is scheduled via a dynamic scheduling, transmitting an extended power headroom report as power headroom information to the base station in the uplink resource. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31)

32. A user equipment for transmitting power headroom information to a base station in an uplink resource, wherein the power headroom information is either a basic power headroom report or an extended power headroom report, and the user equipment is configured to report the power headroom information with extended power headroom reports, the user equipment comprising:
-
a transmitter adapted to transmit a basic power headroom report as power headroom information to the base station in the uplink resource, in case the uplink resource is scheduled via a persistent scheduling configuration and the transmitter is adapted to transmit an extended power headroom report as power headroom information to the base station in the uplink resource, in case the uplink resource is scheduled via a dynamic scheduling. - View Dependent Claims (33, 34, 35, 36)
