摘要

Methods, systems, and devices for wireless communication are described. In one example, a base station may dynamically configure a user equipment (UE) to monitor or avoid monitoring for a preemption indication. Accordingly, the UE may have a lower chance of monitoring for a preemption indication when it is unlikely that an uplink or downlink transmission will be preempted. In another example, a base station may transmit a control message indicating whether future indications received from the base station are to be interpreted as preemption indications or permission indications. Accordingly, the base station may choose to use either preemption indications or permission indications (e.g., based on the probability of collisions between mobile broadband (MBB) and low latency transmissions) to facilitate MBB and low latency communication multiplexing with limited signaling.

說明書

In the example of FIG. 4, base station 105-b may transmit an interpretation indication 410 (e.g., in an RRC message) on carrier 405-a that indicates whether UE 115-b is to interpret future indications received from base station 105-b and pertaining to uplink transmissions on a carrier as either preemption indications or permission indications. That is, since preemption indications and permission indications may be transmitted in DCI having a same format (i.e., signaled using the same mechanism (e.g., same bit)), and the UE 115-b may monitor for preemption indications and permission indications using the same techniques, it may be appropriate for UE 115-b to identify whether DCI received from base station 105-b includes a preemption indication or a permission indication for MBB and low latency communication multiplexing.

The interpretation indication 410 may be a one-bit field, where a one may indicate that future indications received from base station 105-b and pertaining to uplink transmissions on a carrier correspond to preemption indications, and a zero may indicate that future indications received from base station 105-b and pertaining to uplink transmissions on a carrier correspond to permission indications (or vice versa). That is, the interpretation indication 410 may indicate to UE 115-b that the use case or purpose of future indications corresponds to preemption indications or permission indications. UE 115-b may therefore receive the interpretation indication 410 and may determine whether to interpret future indications as preemption indications or permission indications.
