COEXISTENCE OF GRANT-BASED AND GRANT-FREE UPLINK TRANSMISSIONS IN A CHANNEL

摘要

Aspects of this disclosure mitigate interference in a time division duplexed frame by altering a transmission parameter of grant-based uplink transmissions upon determining that a portion of the grant-based transmission will coincide with the retransmission of a detected grant-free uplink transmission. In particular, a base station may determine that a grant-free retransmission is to occur over resources scheduled to carry a grant-based transmission, and then send a signal instructing a UE to delay, or puncture a portion, of the grant-based transmission. This may mitigate interference between the grant-based transmission and the grant-free transmission.
