Abstract
Methods, apparatuses, and software can be used for providing power headroom reporting in a telecommunication system. A method can include configuring a user equipment to send a power headroom report control element in uplink, wherein the power headroom report control element includes a bitmap indicating which power headroom reports are being reported. The method can further include receiving the power headroom report control element from the user equipment. The method additionally can include processing the received power headroom report control element based on the configuration of the user equipment.
Claims10
A non-transitory computer-readable medium including code for performing a process to be executed on a computer, the process comprising:
- configuring a user equipment, at a time, to send a first media access control (MAC) subheader and a first power headroom report (PHR) control element, the first MAC subheader including a first logical channel identifier (LCID), the first LCID corresponding to a power headroom report for a single component carrier;
- receiving the first PHR control element from the user equipment;
- processing the first PHR control element;
- configuring the user equipment, at another time, to send a second MAC subheader and a second PHR control element, the second MAC subheader including a second LCID, the second LCID indicating a bitmap in the second PHR control element, the bitmap including a plurality of bits for power headroom reports for a plurality of secondary cells;
- receiving the second PHR control element from the user equipment;
- and
- processing the second PHR control element.
A non-transitory computer-readable medium including code for performing a process to be executed on a computer, the process comprising:
- preparing, at a time, a first media access control (MAC) subheader and a first power headroom report (PHR) control element, the first MAC subheader including a first logical channel identifier (LCID), the first LCID corresponding to a power headroom report for a single component carrier;
- sending the first MAC subheader and the first PHR control element to a base station;
- preparing, at another time, a second MAC subheader and a second PHR control element, the second MAC subheader including a second LCID, the second LCID indicating a bitmap in the second PHR control element, the bitmap including a plurality of bits for power headroom reports for a plurality of secondary cells;
- and
- sending the second MAC subheader and the second PHR control element to the base station.
