Abstract
A method for reporting a power headroom report (PHR) is performed by a terminal. The method includes: transmitting cooperatively physical uplink shared channels (PUSCHs) towards multiple transmission reception points (TRPs); measuring a power headroom (PH) on one or more cooperative TRPs; and reporting the PHR on the one or more cooperative TRPs according to the PH on the one or more cooperative TRPs.
Claims18
A method for reporting a power headroom report (PHR), performed by a terminal, the method comprising:
- transmitting cooperatively physical uplink shared channels (PUSCHs) towards multiple transmission reception points (TRPs);
- measuring a power headroom (PH) on one or more cooperative TRPs;
- and
- reporting the PHR on the one or more cooperative TRPs according to the PH on the one or more cooperative TRPs;
- wherein measuring the PH on the one or more cooperative TRPs comprises:
- determining that the terminal does not transmit a PUSCH actually, and measuring a virtual PH of the PUSCH according to a default or predefined reference format corresponding to a single TRP or multiple TRPs as a calculation assumption;
- wherein reporting the PHR on the one or more cooperative TRPs according to the PH on the one or more cooperative TRPs comprises:
- reporting the PHR comprising the virtual PH corresponding to the PUSCH.
A method for reporting a power headroom report (PHR), performed by a network device, the method comprising:
- configuring a terminal to transmit cooperatively physical uplink shared channels (PUSCHs) towards multiple transmission reception points (TRPs);
- configuring the terminal to measure a power headroom (PH) on one or more cooperative TRPs and report the PHR on the one or more cooperative TRPs according to the PH on the one or more cooperative TRPs;
- and
- obtaining the PHR on the one or more cooperative TRPs, reported by the terminal;
- wherein configuring the terminal to measure and report the PHR on the one or more cooperative TRPs comprises:
- in response to that the terminal does not transmit a PUSCH actually, configuring the terminal to measure a virtual PH of the PUSCH according to a default or predefined reference format corresponding to a single TRP or multiple TRPs as a calculation assumption, and configuring the terminal to report the PHR comprising the virtual PH corresponding to the PUSCH;
- wherein configuring the terminal to report the PHR comprising the virtual PH corresponding to the PUSCH comprises:
- configuring the terminal to determine a PUSCH reference format according to a reference cooperative transmission mode corresponding to transmitting cooperatively the PUSCHs towards the multiple TRPs;
- and
- configuring the terminal to report the PHR comprising the virtual PH corresponding to the PUSCH according to the PUSCH reference format.
A device for reporting a power headroom report (PHR), comprising
- a processor;
- and
- a memory for storing processor-executable instructions;
- wherein the processor is configured to:
- transmit cooperatively physical uplink shared channels (PUSCHs) towards multiple transmission reception points (TRPs);
- measure a power headroom (PH) on one or more cooperative TRPs;
- and
- report the PHR on the one or more cooperative TRPs according to the PH on the one or more cooperative TRPs;
- wherein the processor is further configured to:
- determine that the terminal does not transmit a PUSCH actually, measure a virtual PH of the PUSCH according to a default or predefined reference format corresponding to a single TRP or multiple TRPs as a calculation assumption;
- wherein the processor is further configured to:
- report the PHR comprising the virtual PH corresponding to the PUSCH.
