Abstract
The present application relates to wireless devices and components including apparatus, systems, and methods for time-domain resource allocation for configured grant transmissions in New Radio (NR) systems operating on unlicensed spectrum. In some embodiments, a user equipment may be configured with periodicity, bitmap information, duration information, or slot-offset information to facilitate the time-domain resource allocation.
Claims20
One or more non-transitory, computer-readable storage-media having instructions that, when executed by one or more processors, cause a user equipment “UE” to:
- process one or more configuration messages from a gNB to determine a configured grant “CG” periodicity and a bitmap that is to indicate a plurality of time-domain resources of an unlicensed spectrum that are available for CG uplink transmissions to the gNB;
- and
- encode, based on the CG periodicity and the bitmap, a CG uplink transmission to be transmitted to the gNB in one or more time-domain resources of the plurality of time-domain resources.
A gNB comprising:
- protocol processing circuitry to:
- identify bitmap information that includes information corresponding to a bitmap that indicates whether time-domain resources of an unlicensed spectrum are available for configured grant uplink transmissions from a user equipment “UE” to the gNB;
- and
- encode the bitmap information in a radio resource control “RRC” message;
- and
- radio-frequency front-end circuitry, coupled with the protocol processing circuitry, to transmit the bitmap information to the UE.
A method of performing a configured grant transmission at a user equipment “UE,” the method comprising:
- receiving, in one or more configuration messages, slot-offset configuration information to configure a plurality of slot offsets within a configured grant periodicity and duration information to indicate a number of consecutive resources that are allocated for configured grant after individual slot offsets of the plurality of slot offsets;
- and
- selecting uplink resources based on the slot-offset configuration information and the duration information;
- and
- encoding a configured grant uplink transmission using the selected uplink resources.
