Abstract
A method and apparatus for power headroom reporting are provided. The power headroom reporting method for a mobile terminal may include determining whether a Physical Uplink Shared Channel (PUSCH) transmission and a Physical Uplink Control Channel (PUCCH) transmission are allowed to occur in a same subframe; determining whether an event for requesting power headroom reporting is generated; and reporting a first power headroom and a second power headroom to a base station.
Claims20
A power headroom reporting method for a mobile terminal, comprising:
- reporting, upon detection of an event requesting power headroom reporting, by the mobile terminal, a first power headroom and a second power headroom to a base station.
An apparatus for power headroom reporting, comprising a mobile terminal for supporting a power headroom reporting function, and reporting, upon detection of an event requesting power headroom reporting, a first power headroom and a second power headroom to a base station.
A resource allocation method for a base station using power headroom reporting, comprising:
- determining whether a mobile terminal is allowed to conduct both a Physical Uplink Shared Channel (PUSCH) transmission and a Physical Uplink Control Channel (PUCCH) transmission in a same subframe;
- receiving, when the mobile terminal is allowed to conduct both the PUSCH transmission and the PUCCH transmission in the same subframe, from the mobile terminal, a report including a power headroom that is determined by subtracting a transmit power for the PUSCH transmission and a transmit power for the PUCCH transmission from a maximum transmit power according to a power class of the mobile terminal;
- and
- allocating resources to the mobile terminal on a basis of the received power headroom in a scheduled subframe at which the mobile terminal conducts the PUSCH transmission and the PUCCH transmission.
An apparatus for power headroom reporting comprising a base station for performing resource allocation using power headroom reporting, determining whether a mobile terminal is allowed to conduct both a PUSCH transmission and a PUCCH transmission in a same subframe, receiving, when the mobile terminal is allowed to conduct both the PUSCH transmission and the PUCCH transmission in the same subframe, a report including a power headroom that is determined by subtracting a transmit power for PUSCH transmission and a transmit power for PUCCH the transmission from a maximum transmit power according to a power class of the mobile terminal, and allocating resources to the mobile terminal on a basis of the received power headroom in a scheduled subframe in which the mobile terminal conducts the PUSCH transmission and the PUCCH transmission.
