Abstract
Certain aspects of the present disclosure relate to methods and apparatus for uplink grant design for Narrow-Band Internet of Things (NB-IoT). A method is provided for wireless communications by a user equipment (UE). The method generally includes receiving an uplink grant indicating one or more tones within a resource block (RB) allocated to the UE for narrowband communication and transmitting using the one or more tones indicated in the uplink grant.
Claims48
A method for wireless communications by a user equipment (UE), comprising:
- receiving an uplink grant indicating, via a set of bits, one or more tones within a resource block (RB) allocated to the UE for narrowband communication using a scheduling unit size of at least one of:
- a single tone, three tones, six tones, or twelve tones, wherein:
- different values of the set of bits indicate different combinations of one or more contiguous tones within the RB;
- the different combinations are based on the scheduling unit size;
- and
- starting tone positions for the different combinations of one or more contiguous tones are restricted such that there is one combination for a scheduling unit size of twelve tones, two combinations for a scheduling unit size of six tones, four combinations for a scheduling unit size of three tones, and twelve combinations for a scheduling unit size of a single tone;
- and
- transmitting using the one or more tones indicated in the uplink grant.
