Abstract
Methods and apparatuses for radio frequency exposure mitigation. A method for a user equipment (UE) to transmit a first channel includes receiving first information for a first downlink reference signal (DL RS) and a set of numbers of repetitions. The method further includes determining a first reference signal received power (RSRP) value for the first DL RS, a first spatial filter corresponding to the first DL RS, a first exposure value for the first spatial filter, and a first number of repetitions from the set of numbers of repetitions based on the first RSRP value and the first exposure value. The method further includes transmitting the first channel with the first number of repetitions using the first spatial filter.
Claims20
A method for transmitting a first channel, the method comprising:
- identifying first information for a set of ranges of exposure values;
- receiving second information for:
- a first downlink reference signal (DL RS),
- a set of ranges of reference signal received power (RSRP) values for the first DL RS,
- a set of numbers of repetitions, and
- a mapping among:
- the set of ranges of RSRP values,
- the set of ranges of exposure values, and
- the set of numbers of repetitions;
- determining:
- a first RSRP value for the first DL RS,
- a first spatial filter corresponding to the first DL RS,
- a first exposure value for the first spatial filter, and
- a first number of repetitions from the set of numbers of repetitions based on the first RSRP value, the first exposure value, and the mapping;
- and
- transmitting the first channel with the first number of repetitions using the first spatial filter.
A user equipment (UE) comprising:
- a processor configured to identify first information for a set of ranges of exposure values;
- and
- a transceiver operably coupled to the processor, the transceiver configured to receive first information for:
- a first downlink reference signal (DL RS),
- a set of ranges of reference signal received power (RSRP) values for the first DL RS,
- a set of numbers of repetitions for transmission of a first channel, and
- a mapping among:
- the set of ranges of RSRP values,
- the set of ranges of exposure values, and
- the set of numbers of repetitions;
- wherein the processor is further configured to determine:
- a first RSRP value for the first DL RS,
- a first spatial filter corresponding to the first DL RS,
- a first exposure value for the first spatial filter, and
- a first number of repetitions from the set of numbers of repetitions based on the first RSRP value, the first exposure value, and the mapping, and
- wherein the transceiver is further configured to transmit the first channel with the first number of repetitions using the first spatial filter.
A base station comprising:
- a processor configured to identify first information for a set of ranges of exposure values, and
- a transceiver operably coupled to the processor, the transceiver configured to:
- transmit second information for:
- a first downlink reference signal (DL RS),
- a set of ranges of reference signal received power (RSRP) values for the first DL RS,
- a set of numbers of repetitions for reception of a first channel, and
- a first mapping among:
- the set of ranges of RSRP values,
- the set of ranges of exposure values, and
- the set of numbers of repetitions;
- and
- receive the first channel with a first number of repetitions from the set of numbers of repetitions.
