Abstract
A user equipment (UE) that shares a radio frequency (RF) path between wireless communication for a first radio access technology (RAT) on a first frequency band and a second RAT on a second frequency band transmits an indication, to a network of the first RAT or the second RAT, indicating a shared RF path between the first RAT and the second RAT. A base station receives the indication from the UE and wireless communication with the UE based on the shared RF path at the UE.
Claims30
An apparatus for wireless communication at a user equipment (UE), comprising:
- memory;
- and
- at least one processor coupled to the memory and configured to:
- share a radio frequency (RF) path between wireless communication for a first radio access technology (RAT) on a first frequency band and a second RAT on a second frequency band, wherein the RF path is based on a number of RF shared chains that are shared between the first RAT on the first frequency band and the second RAT on the second frequency band;
- transmit an indication, to a network of the first RAT or the second RAT, wherein the indication indicates the number of the RF shared chains for the shared RF path between the first RAT and the second RAT and a list of frequency band combinations associated with the shared RF path including the first frequency band and the second frequency band;
- and
- receive a configuration for dual connectivity based on the first RAT and the second RAT.
A method of wireless communication at a user equipment (UE), comprising:
- sharing a radio frequency (RF) path between wireless communication for a first radio access technology (RAT) on a first frequency band and a second RAT on a second frequency band, wherein the RF path is based on a number of RF shared chains that are shared between the first RAT on the first frequency band and the second RAT on the second frequency band;
- transmitting an indication, to a network of the first RAT or the second RAT, indicating the number of the RF shared for the shared RF path between the first RAT and the second RAT and a list of frequency band combinations associated with the shared RF path including the first frequency band and the second frequency band;
- and
- receiving a configuration for dual connectivity based on the first RAT and the second RAT.
An apparatus for wireless communication at a base station, comprising:
- memory;
- and
- at least one processor coupled to the memory and configured to:
