Half-duplex operation in dual connectivity

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• a transceiver configured to receive a first slot format configuration for a first cell and a second slot format configuration for a second cell, the first cell being associated with a first radio access technology (RAT) and a first radio frequency (RF) spectrum band and the second cell being associated with a second RAT and a second RF spectrum band;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• identify, for at least a portion of a transmission time interval (TTI), a conflict between a first communication direction on the first RF spectrum band for the first cell and a second communication direction on the second RF spectrum band for the second cell;
• and
• determine, in response to the identified conflict, that the first cell has a priority over the second cell, wherein the priority is determined based at least in part on the first slot format configuration and the second slot format configuration, or the first RF spectrum band and the second RF spectrum band, or a combination thereof;
• wherein
• the transceiver is further configured to communicate, during the portion of the TTI, on the first cell in the first communication direction based at least in part on the first cell having the priority over the second cell.

An apparatus for wireless communication at a user equipment (UE), comprising:

• means for receiving a first slot format configuration for a first cell and a second slot format configuration for a second cell, the first cell being associated with a first radio access technology (RAT) and a first radio frequency (RF) spectrum band and the second cell being associated with a second RAT and a second RF spectrum band;
• means for identifying, for at least a portion of a transmission time interval (TTI), a conflict between a first communication direction on the first RF spectrum band for the first cell and a second communication direction on the second RF spectrum band for the second cell;
• means for determining, in response to the identified conflict, that the first cell has a priority over the second cell, wherein the priority is determined based at least in part on the first slot format configuration and the second slot format configuration, or the first RF spectrum band and the second RF spectrum band, or a combination thereof;
• and
• means for communicating, during the portion of the TTI, on the first cell in the first communication direction based at least in part on the first cell having the priority over the second cell.

A non-transitory computer-readable medium storing code for wireless communication at a user equipment (UE), the code comprising instructions executable by a processor to:

• receive a first slot format configuration for a first cell and a second slot format configuration for a second cell, the first cell being associated with a first radio access technology (RAT) and a first radio frequency (RF) spectrum band and the second cell being associated with a second RAT and a second RF spectrum band;
• identify, for at least a portion of a transmission time interval (TTI), a conflict between a first communication direction on the first RF spectrum band for the first cell and a second communication direction on the second RF spectrum band for the second cell;
• determine, in response to the identified conflict, that the first cell has a priority over the second cell, wherein the priority is determined based at least in part on the first slot format configuration and the second slot format configuration, or the first RF spectrum band and the second RF spectrum band, or a combination thereof;
• and
• communicate, during the portion of the TTI, on the first cell in the first communication direction based at least in part on the first cell having the priority over the second cell.
