Gap configuration in wireless communications
A method of wireless communication may include determining a gap configuration for a mobile device, wherein the gap configuration defines a desired gap between a scheduled downlink transmission for reception by a mobile device and an uplink transmission from the mobile device; determining whether a gap between a scheduled downlink transmission for reception by a mobile device and an uplink transmission from the mobile device is less than a defined number of symbols for the desired gap; and/or puncturing at least one of the downlink transmission and the uplink transmission when the gap is determined to be less than the defined number of symbols. The puncturing may be performed on the downlink transmission and/or the uplink transmission when the scheduled gap is less than a desired gap, and optionally the puncturing is performing without puncturing a CSI-RS, a DMRS, or a PTRS. Other aspects and features are also claimed and described.
