METHOD AND APPARATUS FOR POWER HEADROOM REPORTING FOR UPLINK DATA REPETITIVE TRANSMISSION IN NETWORK COOPERATIVE COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17858897 titled 'METHOD AND APPARATUS FOR POWER HEADROOM REPORTING FOR UPLINK DATA REPETITIVE TRANSMISSION IN NETWORK COOPERATIVE COMMUNICATIONS

Simplified Explanation

The abstract describes a method performed by a user equipment (UE) in a wireless communication system. The method involves receiving higher layer configuration information from a base station, which includes information associated with a sounding reference signal (SRS) resource set and downlink control information (DCI) containing scheduling information for a physical uplink shared channel (PUSCH). The UE then identifies a plurality of SRS resource indicators (SRIs) for PUSCH repetition from the DCI, in case two SRS resource sets are configured. Based on the identified SRIs, the UE determines an SRS resource for the PUSCH repetition. Additionally, the UE calculates a power headroom report (PHR) by comparing a first PHR based on actual transmission with a second PHR based on a reference format configured from the higher layer configuration information. Finally, the UE transmits the determined PHR on the PUSCH.
