Abstract
Methods and apparatuses for wireless communications are described. The aspects relate to a frame structure for new radio shared spectrum. For instance, the frame structure may provide shared medium access by multiple operators in a new radio shared spectrum system. Specifically, the present aspects provide for utilizing reservation preambles associated with a distinct operator for announcing to other operators a reservation of at least one transmission opportunity of a given frame in the new radio shared spectrum.
Claims20
A method of wireless communications at a user equipment (UE) associated with a first operator, comprising:
- receiving, on a preamble timeslot assigned to the first operator from a network entity, a downlink reservation preamble;
- and
- transmitting, within the preamble timeslot assigned to the first operator and subsequent to the reception of the downlink reservation preamble, an uplink reservation preamble of the first operator to a second network entity.
An apparatus for wireless communications, comprising:
- a memory;
- and
- a processor coupled to the memory and configured to:
- receive, on a preamble timeslot assigned to the first operator from a network entity, a downlink reservation preamble;
- and
- transmit, within the preamble timeslot assigned to the first operator and subsequent to the reception of the downlink reservation preamble, an uplink reservation preamble of the first operator to a second network entity.
A non-transitory computer-readable medium storing computer code executable by a processor for wireless communication, comprising code for:
- receiving, on a preamble timeslot assigned to a first operator from a network entity, a downlink reservation preamble;
- and
- transmitting, within the preamble timeslot assigned to the first operator and subsequent to the reception of the downlink reservation preamble, an uplink reservation preamble of the first operator to a second network entity.
