Dynamic power control for priority based traffic
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a deadline prior to a first uplink transmission associated with a secondary cell group (SCG), wherein the first uplink transmission is associated with a first priority level; determine whether to perform a second uplink transmission associated with a master cell group (MCG), wherein the second uplink transmission is initiated after the deadline, and wherein the second uplink transmission is associated with a second priority level; and adjust a transmit power of the first uplink transmission based at least in part on at least one of: determining whether to perform the second uplink transmission, or the first priority level and the second priority level. Numerous other aspects are provided.
1. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors coupled to the memory, wherein the one or more processors are configured to:
obtain uplink data for transmission on a component carrier associated with a master cell group (MCG), wherein the uplink data is obtained after a deadline associated with a time offset;
transmit the uplink data in a non-downlink control information (DCI)-scheduled physical uplink shared channel (PUSCH) transmission associated with the MCG, wherein the non-DCI-scheduled PUSCH transmission is associated with a first priority level; and
adjust a transmit power of a DCI-scheduled PUSCH transmission irrespective of the first priority level associated with the non-DCI-scheduled PUSCH transmission and a second priority level associated with the DCI-scheduled PUSCH transmission, wherein:
the DCI-scheduled PUSCH transmission is associated with a secondary cell group (SCG),
the non-DCI-scheduled PUSCH transmission overlaps in time with the DCI-scheduled PUSCH transmission,
the transmit power is adjusted according to a power sharing configuration that is based at least in part on the uplink data being obtained after the deadline,
the adjustment comprises a reduction of the transmit power of the DCI-scheduled PUSCH transmission partway through the DCI-scheduled PUSCH transmission, and
the DCI-scheduled PUSCH transmission is associated with a phase discontinuity based at least in part on the transmit power of the DCI-scheduled PUSCH transmission being reduced partway through the DCI-scheduled PUSCH transmission.
2. The UE of claim 1 , wherein, to adjust the transmit power of the DCI-scheduled PUSCH transmission irrespective of the first priority level associated with the non-DCI-scheduled PUSCH transmission and the second priority level associated with the DCI-scheduled PUSCH transmission, the one or more processors are configured to adjust, based at least in part on the second priority level failing to satisfy a priority threshold, the transmit power of the DCI-scheduled PUSCH irrespective of the first priority level associated with the non-DCI-scheduled PUSCH transmission and the second priority level associated with the DCI-scheduled PUSCH transmission.
3. The UE of claim 1 , wherein the non-DCI-scheduled PUSCH transmission is a configured grant (CG) PUSCH transmission and the DCI-scheduled PUSCH transmission is a dynamic grant (DG) PUSCH transmission.
4. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors coupled to the memory, wherein the one or more processors are configured to:
determine a deadline prior to a first uplink transmission associated with a secondary cell group (SCG), wherein the first uplink transmission is associated with a first priority level that satisfies a priority threshold;
determine whether to perform a second uplink transmission associated with a master cell group (MCG), wherein the second uplink transmission is initiated after the deadline, and wherein the second uplink transmission is associated with a second priority level; and
adjust a transmit power of the first uplink transmission as if the second uplink transmission is to be performed irrespective of whether the second uplink transmission is initiated, wherein:
the adjustment comprises a reduction of the transmit power of the first uplink transmission partway through the first uplink transmission,
the first uplink transmission is associated with a phase discontinuity based at least in part on the reduction of the transmit power of the first uplink transmission partway through the first uplink transmission, and
the adjustment is based at least in part on at least one of:
the determination whether to perform the second uplink transmission, or
the first priority level and the second priority level.
5. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors coupled to the memory, wherein the one or more processors are configured to:
determine a deadline prior to a first uplink transmission associated with a secondary cell group (SCG), wherein the first uplink transmission is associated with a first priority level that fails to satisfy a priority threshold;
determine whether to perform a second uplink transmission associated with a master cell group (MCG), wherein the second uplink transmission is initiated after the deadline, and wherein the second uplink transmission is associated with a second priority level; and
adjust a transmit power of the first uplink transmission irrespective of the first priority level and the second priority level, the adjustment based at least in part on the determination whether to perform the second uplink transmission, wherein:
the adjustment comprises a reduction of the transmit power of the first uplink transmission partway through the first uplink transmission, and
the first uplink transmission is associated with a phase discontinuity based at least in part on the transmit power of the first uplink transmission being reduced partway through the first uplink transmission.
6. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors coupled to the memory, wherein the one or more processors are configured to:
determine a deadline prior to a first uplink transmission associated with a secondary cell group (SCG), wherein the first uplink transmission is associated with a first priority level that satisfies a priority threshold;
determine whether to perform a second uplink transmission associated with a master cell group (MCG), wherein the second uplink transmission is initiated after the deadline, and wherein the second uplink transmission is associated with a second priority level; and
adjust a transmit power of the first uplink transmission based at least in part on at least one of:
the determination whether to perform the second uplink transmission, or
the first priority level and the second priority level,
wherein the adjustment comprises a reduction of the transmit power of the first uplink transmission partway through the first uplink transmission based at least in part on the first priority level satisfying the priority threshold and the second uplink transmission being initiated after the deadline, and
