Abstract
Aspects of the present disclosure provide for various methods and apparatuses for mitigating intra-cell interference when multiplexing grant-less traffic and grant-based traffic. When a wireless device transmits data without first requesting a grant of certain network resources from a base station, such data transmission may be called grant-less traffic in this disclosure. Different from grant-less traffic, when a wireless device needs to request a grant of certain network resources before transmitting data, such data may be called grant-based traffic in this disclosure.
Claims26
A method of wireless communication operable at a scheduling entity, the method comprising:
- communicating with a plurality of user equipments (UEs) utilizing a plurality of slots configured to multiplex grant-based traffic and grant-less traffic;
- determining interference to the grant-based traffic caused by the grant-less traffic;
- and
- transmitting control information to the plurality of UEs, to mitigate the interference by statistically controlling a number of the plurality of UEs that transmit grant-less traffic in one or more of the plurality of slots.
A method of wireless communication operable at a user equipment, the method comprising:
- communicating with a scheduling entity utilizing a plurality of slots configured to multiplex grant-based traffic and grant-less traffic;
- receiving control information from the scheduling entity;
- determining a first probability of transmitting grant-less traffic in one or more of the plurality of slots based on the control information;
- determining a second probability of transmitting grant-based traffic in one or more of the plurality of slots based on the control information;
- and
- transmitting grant-less traffic and grant-based traffic based on the first probability and the second probability.
A wireless communication apparatus comprising:
- a communication interface configured to communicate with a plurality of user equipments (UEs);
- a memory;
- and
- a processor operatively coupled to the memory and communication interface,
- wherein the memory and the processor are configured to:
- communicate with the plurality of UEs utilizing a plurality of slots configured to multiplex grant-based traffic and grant-less traffic;
- determine interference to the grant-based traffic caused by the grant-less traffic;
- and
- transmit control information to the plurality of UEs, to mitigate the interference by statistically controlling a number of the plurality of UEs that transmit grant-less traffic in one or more of the plurality of slots.
