Claim of US Patent No. 10,973,070

1. A base station, comprising:at least one antenna;
at least one radio, wherein the at least one radio is configured to perform cellular communication using a first radio access technology (RAT);
one or more processors coupled to the at least one radio, wherein the one or more processors and the at least one radio are configured to perform voice and/or data communications;
wherein the one or more processors are configured to cause the base station to:
receive a first capability indicating that a user equipment device (UE) supports uplink (UL) sharing for one or more system bandwidths in a dual connectivity configuration with the first RAT and a second RAT;
receive a second capability indicating binary information indicating one of no switching gap needed and switching gap needed;
coordinate UL resources over an interface with a second base station serving a second cell using a second RAT; and
transmit an allocation of first UL resources associated with a first cell served by the base station using the first RAT to the UE, wherein the allocation of first UL resources is in accordance with time division multiplexing (TDM) for UL data transmissions for the first RAT and the second RAT.
