Terminal apparatus and method
The present invention efficiently performs communication. Included are a transmitter configured to transmit a measurement report including a measurement result for a serving cell c and/or a PUSCH for the serving cell c, wherein in a case that the number of SS blocks and/or CSI-RSs used for the RSRP measurement is greater than one for the serving cell c, the measurement result of RSRP included in the measurement report and the RSRP used for evaluation of a path loss for transmit power of the PUSCH are calculated separately.
1. A terminal apparatus comprising:
a receiver configured to receive one or more Synchronization Signal and Physical Broadcast Channel (SS) blocks or Channel State Information Reference Signals (CSI-RSs);
a channel statement measurement unit configured to perform a first Reference Signal Received Power (RSRP) measurement by using the one or more SS blocks or CSI-RSs for a serving cell c, wherein the channel state measurement unit is also configured to measure a cell quality of the serving cell c by using a second RSRP measurement based on the one or more SS blocks or CSI RSs;
an uplink control information generation unit configured to perform an evaluation of a path loss for transmit power of a Physical Uplink Shared Channel (PUSCH) by using a third RSRP measurement based on one SS block or CSI-RS of the one or more SS blocks or CSI-RSs for the serving cell c; and
a transmitter configured to transmit a measurement report including a first measurement result of the RSRP for the serving cell c, a second measurement result of the RSRP for the cell quality of the serving cell c, and a third measurement result of the RSRP for the PUSCH for the serving cell c, wherein in a case that more SS blocks or CSI-RSs are used for the first RSRP measurement than are used for the third RSRP measurement, the first measurement result of the RSRP and the third measurement result of the RSRP are calculated separately, and wherein in a case that multiple SS blocks or CSI-RSs are used for the second RSRP measurement, the second measurement result is an average of those RSRPs of the multiple SS blocks or CSI-RSs that are greater than a predetermined threshold.
2. The terminal apparatus according to claim 1 , wherein in a case that the first measurement result of the RSRP is calculated by using multiple SS blocks or CSI-RSs of the one or more SS blocks or CSI-RSs for the serving cell c, one common transmit power value is configured for the multiple SS blocks or CSI-RSs.
3. The terminal apparatus according to claim 2 , wherein in a case that the measurement report is transmitted by using the PUSCH for the serving cell c, the path loss for the transmit power of the PUSCH is evaluated based on the first measurement result of the RSRP included in the measurement report, and wherein whether or not the path loss for the transmit power of the PUSCH is evaluated by using the first measurement result of the RSRP is determined based on a higher layer parameter or a value of a field included in a downlink control information (DCI) format.
4. The terminal apparatus according to claim 1 , wherein in a case that the first measurement result of the RSRP is based on one SS block or CSI-RS of the one or more SS blocks or CSI-RSs, whether or not that one SS block or CSI-RS corresponding to the first measurement result is identical to the one SS block or CSI-RS used for the evaluation of the path loss that results in the third measurement result is determined based on a higher layer parameter.
5. A method comprising the steps of:
receiving one or more Synchronization Signal and Physical Broadcast Channel (SS) blocks and/or Channel State Information Reference Signals (CSI-RSs);
performing a first Reference Signal Received Power (RSRP) measurement by using the one or more SS blocks or CSI-RSs for a serving cell c;
measuring a cell quality of the serving cell c by using a second RSRP measurement based on one or more SS blocks or CSI-RSs;
performing path loss evaluation for transmit power of a Physical Uplink Shared Channel (PUSCH) by using a third RSRP measurement based on one SS block or CSI-RS of the one or more SS blocks or CSI-RSs for the serving cell c; and
transmitting a measurement report including a first measurement result of the RSRP for the serving cell c, a second measurement result of the RSRP for the cell quality of the serving cell c, and a third measurement result of the RSRP for the PUSCH for the serving cell c, wherein in a case that more SS blocks or CSI-RSs are used for the first RSRP measurement than care used for the third RSRP measurement, the first measurement result of the RSRP and the third measurement result of the RSRP are calculated separately, and wherein in a case that multiple SS blocks or CSI-RSs are used for the second RSRP measurement, the second measurement result is an average of those RSRPs of the multiple SS blocks or CSI-RSs that are greater than a predetermined threshold.
