Embodiment Construction

[0023] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0024] Referring to Chapter 7 of 3GPP TS 38.213 Vf30 and 3GPP TS 38.101-2 Vf30, for an activated cell, whether the PHR of the serving cell determined by the terminal device is based on the real power value or the assumed power value:

[0025] Based on the real power value, the power headroom is calculated as: carrier maximum power value - real power v...

Abstract

The invention discloses a power headroom reporting method, which is used for terminal equipment and is characterized in that N reported PUSCHs (Physical Uplink Shared Channel) are included in a time unit, and N is greater than or equal to 2; wherein each reported PUSCH is a PUSCH used for sending a power headroom report; wherein the power headroom report comprises power headroom values of M carriers, the time unit is a time unit of a timer triggering power headroom report, N is greater than or equal to 2, and M is greater than or equal to 2. The invention further comprises terminal equipment using the method. The transmission efficiency of PHR can be improved, and the scheduling accuracy of the network equipment is improved.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a method and apparatus for reporting power headroom of terminal equipment. 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 PHR through MAC CE, including the PH value. PH indicates how much headroom is available on the current carrier except for the PUSCH transmission power. The PH value can be used as a reference for network equipment to allocate uplink resource blocks. If the PH value is negative, it means that the current PUSCH transmission power has exceeded the maximum transmission power allowed by the terminal equipment, and the resource block allocation of the terminal equipment can be reduced in the next scheduling; If the PH value is positive, the number of res...
