Abstract

The present application discloses a method for determining a power headroom, which is used for a terminal device, comprising the following steps: determining a reporting PUSCH for sending a power headroom report, and the reporting PUSCH is located on a first carrier; in the target carrier, determining and At least one symbol in the first time slot where the reported PUSCH overlaps is a target symbol set, and the PUSCH time overlapping with the target symbol set is determined as the target PUSCH, and the power headroom value of the target carrier is calculated. The present application also discloses a terminal device for determining a power headroom. The invention solves the problem that the prior art cannot effectively determine the PUSCH basis for calculating the power headroom value.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a method and device for determining a power headroom. Background technique [0002] The network device receives a power headroom report (PHR, Power Headroom Report) from the terminal device while controlling the uplink transmission power of the terminal device. The terminal device sends a PHR to the terminal device through the MAC CE, including the PH parameters of each carrier. PH indicates the available power of the terminal equipment in addition to the PUSCH transmission power of the current carrier. If the PH is a negative value, it means that the network device has scheduled a data transmission rate for the terminal device that is higher than its available transmission power can support at that time. The PH value can be used as a reference basis for network equipment to allocate uplink resource blocks. If the PH value is negative, it means that ...
