Transmission preemption for enhanced component carriers
First Claim
1. A method for wireless communication by a first user equipment (UE) in communication with a base station, comprising:
- receiving, at the first UE, a downlink grant that assigns resources for transmission to at least the first UE;
monitoring, at the first UE, for a control signal indicating that a portion of the resources assigned by the downlink grant is to be preempted for transmission to a second UE;
determining, at the first UE based at least in part on the monitoring, whether to process the portion of the resources assigned by the downlink grant indicated to be preempted; and
discontinuing processing, at the first UE based at least in part on the determining, of the portion of the resources assigned by the downlink grant indicated to be preempted.

Abstract
Techniques are described for preempting resource allocations to one or more UEs in the event that delay sensitive data is received. A resource allocation of a number of symbols may be granted to a first user equipment (UE) for first associated data to be transmitted. Subsequently, data may be received for a second UE that is more delay sensitive than the first data. The resource allocation to the first UE may be preempted, and resources allocated to the second UE for the second data within a variable length transmission time interval (TTI) of the resource allocation to the first UE. UEs may monitor for preemption during transmissions to other UEs in order to receive new resource grants associated with the preempted resource grant. Whether a UE monitors transmissions for preemption may be determined based on a quality or service (QoS) of the UE.

12. An apparatus for wireless communication by a first user equipment (UE) in communication with a base station, comprising:
-
means for receiving, at the first UE, a downlink grant that assigns resources for transmission to at least the first UE; means for monitoring, at the first UE, for a control signal indicating that a portion of the resources assigned by the downlink grant is to be preempted for transmission to a second UE; means for determining, at the first UE based at least in part on the monitoring, whether to process the portion of the resources assigned by the downlink grant indicated to be preempted; and means for discontinuing processing, at the first UE based at least in part on the determining, of the portion of the resources assigned by the downlink grant indicated to be preempted. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. An apparatus for wireless communication, comprising:
-
a processor; memory in electronic communication with the processor; and instructions stored in the memory, the instructions being executable by the processor to cause the apparatus to; receive, at a first user equipment (UE), a downlink grant that assigns resources for transmission to at least the first UE; monitor, at the first UE, for a control signal indicating that a portion of the resources assigned by the downlink grant is to be preempted for transmission to a second UE; determine, at the first UE based at least in part on the monitoring, whether to process the portion of the resources assigned by the downlink grant indicated to be preempted; and discontinue processing, at the first UE based at least in part on the determining, of the portion of the resources assigned by the downlink grant indicated to be preempted. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A non-transitory computer-readable medium storing computer-executable code for wireless communication, the code executable by a processor to:
-
receive, at a first user equipment (UE), a downlink grant that assigns resources for transmission to at least the first UE; monitor, at the first UE, for a control signal indicating that a portion of the resources assigned by the downlink grant is to be preempted for transmission to a second UE; determine, at the first UE based at least in part on the monitoring, whether to process the portion of the resources assigned by the downlink grant indicated to be preempted; and discontinue processing, at the first UE based at least in part on the determining, of the portion of the resources assigned by the downlink grant indicated to be preempted.
