A transmitting node determines data for a first service will be transmitted during a time period when data for a second service will be transmitted. The data for the first service requires lower latency than the data for the second service and the data for the first service includes an original set of data for the first service and at least one repetition of the original set of data for the first service. The transmitting node adjusts resources consumed by the data for the first service based on available transmission resources.

Methods, systems, and devices for wireless communications are described. In some examples, a wireless communications system may support group channel quality indicator (CQI) reporting. For example, a user equipment (UE) may receive, from a base station, signaling indicating a group of component carriers (CCs) and one or more subbands within the group of CCs. The UE may receive one or more reference signals within the one or more subbands and determine a group CQI index corresponding to the group of CCs based at least in part on the one or more reference signals. The UE may then transmit a report to the base station indicating the group CQI index and the base station may determine a CQI index for each of the one or more subbands based on the group CQI index.

The method comprises the steps of: determining a selection window; selecting Y candidate slots within the selection window; determining at least one slot related to the Y candidate slots, on the basis of a resource reservation period value set for a resource pool; selecting at least one sidelink (SL) resource from among SL resources included in the Y candidate slots, on the basis of sensing the at least one slot; and performing SL communication on the basis of the at least one SL resource, wherein the value of Y may be a positive integer.
