User terminal
A user terminal according to an aspect of the present disclosure includes a receiving section that receives a channel state information-reference signal (CSI-RS), and a control section that determines whether to control transmission and reception of data at timing to measure the CSI-RS based on whether the control section is able to assume a synchronous environment. According to the aspect of the present disclosure, even when a measurement other than SSB measurement is performed, it is possible to appropriately control transmission and reception of data simultaneously with the measurement.
1. A terminal comprising:
a receiver that receives a channel state information reference signal (CSI-RS); and
a processor that, when the processor is able to assume, based on information regarding whether a neighbor cell is synchronous with a serving cell, that the neighbor cell is synchronous with the serving cell, and when an intra-band carrier aggregation (CA) is configured, applies a scheduling restriction of a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUCCH), a Sounding Reference Signal (SRS), a Physical Downlink Shared Channel (PDSCH), a Physical Downlink Control Channel (PDCCH) and a CSI-RS at an intra-frequency measurement timing of the CSI-RS to all serving cells in a same band.
2. The terminal according to claim 1 , wherein when the processor performs a measurement of the CSI-RS in a time division duplex (TDD) band, the processor does not expect to transmit data having numerology different from that of the CSI-RS on a symbol of the CSI-RS and one symbol before and one symbol after the symbol of the CSI-RS.
3. The terminal according to claim 2 , wherein when the processor performs a measurement of the CSI-RS in a certain frequency band, the processor does not expect to transmit or receive data having numerology different from that of the CSI-RS on a symbol of the CSI-RS.
4. The terminal according to claim 1 , wherein when the processor performs a measurement of the CSI-RS in a certain frequency band, the processor does not expect to transmit or receive data having numerology different from that of the CSI-RS on a symbol of the CSI-RS.
5. The terminal according to claim 4 , wherein the certain frequency band is a frequency band above 24 GHz.
6. A radio communication method for a terminal, comprising:
receiving a channel state information reference signal (CSI-RS); and
when the terminal is able to assume, based on information regarding whether a neighbor cell is synchronous with a serving cell, that the neighbor cell is synchronous with the serving cell, and when an intra-band carrier aggregation (CA) is configured, applying a scheduling restriction of a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUCCH), a Sounding Reference Signal (SRS), a Physical Downlink Shared Channel (PDSCH), a Physical Downlink Control Channel (PDCCH) and a CSI-RS at an intra-frequency measurement timing of the CSI-RS to all serving cells in a same band.
7. A base station comprising:
a transmitter that transmits a channel state information reference signal (CSI-RS) to a terminal; and
a processor that generates information based on which it is able to assume that a neighbor cell is synchronous with a serving cell, and configures an intra-band carrier aggregation (CA), in order to make the terminal perform a control for applying a scheduling restriction of a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUCCH), a Sounding Reference Signal (SRS), a Physical Downlink Shared Channel (PDSCH), a Physical Downlink Control Channel (PDCCH) and a CSI-RS at an intra-frequency measurement timing of the CSI-RS to all serving cells in a same band.
8. A system comprising a terminal and a base station; wherein
the terminal comprises:
a receiver that receives a channel state information reference signal (CSI-RS); and
a first processor that, when the first processor is able to assume, based on information regarding whether a neighbor cell is synchronous with a serving cell, that the neighbor cell is synchronous with the serving cell, and when an intra-band carrier aggregation (CA) is configured, applies a scheduling restriction of a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUCCH), a Sounding Reference Signal (SRS), a Physical Downlink Shared Channel (PDSCH), a Physical Downlink Control Channel (PDCCH) and a CSI-RS at an intra-frequency measurement timing of the CSI-RS to all serving cells in a same band, and
the base station comprises:
a transmitter that transmits the CSI-RS to the terminal; and
a second processor that generates the information and configures the CA.
