Abstract
Official abstract text for this publication.
A user equipment (UE) is described. The UE may comprise higher layer processing circuitry configured to acquire first radio resource control (RRC) information and second RRC information. The first RRC information may indicate a search space set for a detection of a physical downlink control channel (PDCCH) with downlink control information (DCI) format 2_0. The DCI format 2_0 may include a field for indicating a channel occupancy duration. The second information may configure a Channel State Information-Reference Signal (CSI-RS). The UE may also comprise receiving circuitry configured to monitor the PDCCH with the DCI format 2_0. If a set of symbol(s) is indicated as not being within the channel occupancy duration by a value of the field in the DCI format 2_0, the PDCCH may be monitored on the set of symbol(s) and the CSI-RS may not be received on the set of symbol(s).
First claim
Opening claim text (preview).
The invention claimed is: 1. A user equipment (UE) comprising: higher layer processing circuitry configured to acquire first radio resource control (RRC) information and second RRC information, the first RRC information indicating a search space set for a detection of a physical downlink control channel (PDCCH) with downlink control information (DCI)_format 2_0, the DCI format 2_0 including a field for indicating a channel occupancy duration, the second RRC information configuring a channel state information-reference signal (CSI-RS); and receiving circuitry configured to monitor the PDCCH with the DCI format 2_0, wherein if a set of symbol(s) is indicated as not being within the channel occupancy duration by a value of the field in the DCI format 2_0, the CSI-RS is not received on the set of symbol(s). 2. A base station comprising: higher layer processing circuitry configured to send first radio resource control (RRC) information and second RRC information, the first RRC information indicating a search space set for a detection of a physical downlink control channel (PDCCH) with downlink control information (DCI) format 2_0, the DCI format 2_0 including a field for indicating a channel occupancy duration, the second RRC information configuring a channel state information reference signal (CSI-RS); and transmitting circuitry configured to transmit the PDCCH with the DCI format 2_0, wherein if a set of symbol(s) is indicated as not being within the channel occupancy duration by a value of the field in the DCI format 2_0, the CSI-RS is not transmitted on the set of symbol(s). 3. A method for a user equipment (UE), the method comprising: acquiring first radio resource control (RRC) information and acquiring second RRC information, the first RRC information indicating a search space set for a detection of a physical downlink control channel (PDCCH) with downlink control information (DCI) format 2_0, the DCI format 2_0 including a field for indicating a channel occupancy duration, the second RRC information configuring a channel state information reference signal (CSI-RS); and monitoring the PDCCH with the DCI format 2_0, wherein if a set of symbol(s) is indicated as not being within the channel occupancy duration by a value of the field in the DCI format 2_0, the CSI-RS is not received on the set of symbol(s).
