Abstract
Apparatuses, methods, and systems are disclosed for determining a beam for preamble transmission. One apparatus includes a processor that determines a beam from multiple beams for preamble transmission. In response to the multiple beams including one or more beams configured with a contention-free resource, the one or more beams configured with a contention-free resource have a higher priority than other beams of the multiple beams.
Claims20
An apparatus comprising a base unit, the apparatus further comprising:
- a receiver that receives a preamble transmission on a beam, wherein the beam is selected by a user equipment from a plurality of beams, and, in response to the plurality of beams comprising one or more beams that are configured with a contention-free resource, the one or more beams that are configured with a contention-free resource have a higher priority than other beams of the plurality of beams, wherein the user equipment:
- determines a set of suitable beams from the plurality of beams having a signal quality greater than a predetermined threshold;
- in response to the set of suitable beams comprising a single beam configured with the contention-free resource, selects the single beam from the set of suitable beams as the beam for preamble transmission;
- in response to the set of suitable beams comprising multiple beams configured with the contention-free resource, selects one beam from the multiple beams as the beam for preamble transmission;
- and
- in response to the set of suitable beams comprising no beams configured with the contention-free resource, selects one beam from the set of suitable beams without a contention-free resource as the beam for preamble transmission;
- and
- a transmitter that transmits a response to the reception of the preamble transmission.
