Abstract
Certain aspects of the present disclosure relate to communication systems, and more particularly, to techniques for mitigating inter-cell interference for uplink ultra-reliable low latency communications (URLLC).
Claims30
A method for wireless communications by a base station (BS), comprising:
- detecting a decoding failure of at least one grant free transmission received from a first user equipment (UE);
- and
- in response to the detection, triggering at least a second UE to reduce interference between one or more uplink transmissions from the second UE and one or more uplink transmissions subsequent to the at least one grant free transmission from the first UE.
A method for wireless communication by a user equipment (UE), comprising:
- sending at least a first transmission of one or more transmissions to a base station (BS) serving the UE;
- receiving an indication triggering the UE to reduce interference between at least a second transmission of the one or more transmissions and one or more uplink transmissions from another UE;
- and
- in response to the indication, reducing transmission power of the at least second transmission to reduce the interference.

An apparatus for wireless communications, comprising:
- a processing system configured to detect a decoding failure of at least one grant free transmission received from a first user equipment (UE);
- and
- a transmitter configured to, in response to the detection, trigger at least a second UE to reduce interference between one or more uplink transmissions from the second UE and one or more uplink transmissions subsequent to the at least one grant free transmission from the first UE.
An apparatus for wireless communications, comprising:
- a transmitter configured to transmit at least a first transmission of one or more transmissions to a base station (BS) serving the UE;
- a receiver configured to receive an indication triggering the UE to reduce interference between at least a second transmission of the one or more transmissions and one or more uplink transmissions from another UE;
- and
- a processing system configured to, in response to the indication, reduce transmission power of the at least second transmission to reduce the interference.
