Abstract
Technology for a next generation node B (gNB) operable to transmit in multiple bandwidth parts (BWPs) is disclosed. The UE can determine a channel state information reference signal (CSI-RS) symbol location in a first bandwidth part (BWP). The UE can determine a CSI-RS symbol location in a second BWP. The UE can encode the CSI-RS in one or more of the first BWP or the second BWP for transmission to a user equipment (UE). The UE can have a memory interface configured to send to a memory the CSI-RS symbol location.
Claims16
An apparatus of a next generation node B (gNB) configured to transmit in multiple bandwidth parts (BWPs), the apparatus comprising:
- one or more processors configured to:
- determine a channel state information reference signal (CSI-RS) symbol location in a first bandwidth part (BWP);
- determine a CSI-RS symbol location in a second BWP;
- encode the CSI-RS in one or more of the first BWP or the second BWP for transmission to a user equipment (UE);
- and
- decode a signal from the UE to determine that one of:
- the UE supports a first subcarrier spacing (SCS) for the first BWP and a second SCS for the second BWP at a given time;
- or
- the UE supports the first SCS for both the first BWP and the second BWP at a given time;
- and
- a memory interface configured to send to a memory the CSI-RS symbol location.
An apparatus of a user equipment (UE) configured to transmit in multiple bandwidth parts (BWPs) at a given time, the apparatus comprising:
- one or more processors configured to:
- determine a sounding reference signal (SRS) symbol location in a first bandwidth part (BWP);
- determine a SRS symbol location in a second BWP;
- encode the SRS in one or more of the first BWP or the second BWP for transmission to a gNB;
- and
- encode for transmission to the gNB a signal to indicate that one of:
- the UE supports a first subcarrier spacing (SCS) for the first BWP and a second SCS for the second BWP at a given time;
- or
- the UE supports the first SCS for both the first BWP and the second BWP at a given time;
- and
- a memory interface configured to send to a memory the SRS symbol location.
At least one non-transitory machine readable storage medium storing instructions thereon, the instructions, when executed by one or more processors at a next generation node B (gNB), to cause the one or more processors to perform operations including:
- determining a channel state information reference signal (CSI-RS) symbol location in a first bandwidth part (BWP);
- determining a CSI-RS symbol location in a second BWP;
- encoding the CSI-RS in one or more of the first BWP or the second BWP for transmission to a user equipment (UE);
- and
- decoding a signal from the UE to determine that one of:
- the UE supports a first subcarrier spacing (SCS) for the first BWP and a second SCS for the second BWP at a given time;
- or
- the UE supports the first SCS for both the first BWP and the second BWP at a given time.
