Abstract
Certain aspects of the present disclosure relate to methods and apparatus for indicating resource element (RE) channel mapping using communications systems operating according to new radio (NR) technologies.
Claims41
A method of wireless communication by a user equipment (UE), comprising:
- receiving an indication, for one or more subband sets, of one or more resource elements (REs) indicated by channel state information reference signal (CSI-RS) resources;
- and
- performing rate matching around the one or more REs based on the received indication when processing a physical downlink shared channel (PDSCH).
A method of wireless communications by a base station (BS), comprising:
- generating an indication, for one or more subband sets, of one or more resource elements (REs) indicated by channel state information reference signal (CSI-RS) resources;
- and
- transmitting the indication to one or more user equipment (UE) that is configured to perform rate matching around the one or more REs based on the indication when processing a downlink physical shared channel (PDSCH).
A method of wireless communication by a user equipment (UE), comprising:
- receiving an indication, for one or more subband sets, of one or more resource elements (REs) indicated by channel state information reference signal (CSI-RS) resources;
- and
- avoiding mapping a physical downlink shared channel (PDSCH) to the one or more REs based on the received indication.
An apparatus for wireless communication, comprising:
- means for receiving an indication, for one or more subband sets, of one or more resource elements (REs) indicated by channel state information reference signal (CSI-RS) resources;
- and
- means for performing rate matching around the one or more REs based on the received indication when processing a downlink physical shared channel (PDSCH).
An apparatus for wireless communication, comprising:
- means for receiving an indication, for one or more subband sets, of one or more resource elements (REs) indicated by channel state information reference signal (CSI-RS) resources;
- and
- means for avoiding mapping a physical downlink shared channel (PDSCH) to the one or more REs based on the received indication.
