Abstract

DCI can be received. The DCI can include scheduling information for a physical channel carrying a TB. The physical channel can include a plurality of repetitions of the TB. The physical channel can span at least one slot. Each of the plurality of repetitions can be within a slot of the at least one slot. At least one repetition of the plurality of the repetitions can have a different duration than a duration of at least one other repetition of the plurality of the repetitions. A repetition duration of each of the plurality of repetitions can be determined based on a plurality of available symbols for the physical channel. The plurality of available symbols can be determined based on the DCI.

Claims20

Dependent claims

A method at a user equipment, the method comprising:

receiving downlink control information including scheduling information for a physical channel carrying a transport block,
where the scheduling information comprises information of a plurality of allocated symbols for the physical channel,
where the downlink control information further comprises information of a plurality of available symbols within the plurality of allocated symbols,
where the physical channel comprises a plurality of repetitions of the transport block,
where the physical channel spans at least one slot,
where each of the plurality of repetitions is within a slot of the at least one slot, and
where at least one repetition of the plurality of the repetitions has a different duration than a duration of at least one other repetition of the plurality of the repetitions;
and
determining a repetition duration of each of the plurality of repetitions based on the plurality of available symbols for the physical channel,
wherein all of the allocated symbols are not always available symbols.

An apparatus comprising:

a transceiver that receives downlink control information including scheduling information for a physical channel carrying a transport block,
where the scheduling information comprises information of a plurality of allocated symbols for the physical channel,
where the downlink control information further comprises information of a plurality of available symbols within the plurality of allocated symbols,
where the physical channel comprises a plurality of repetitions of the transport block,
where the physical channel spans at least one slot,
where each of the plurality of repetitions is within a slot of the at least one slot, and
where at least one repetition of the plurality of the repetitions has a different duration than a duration of at least one other repetition of the plurality of the repetitions;
and
a controller coupled to the transceiver, where the controller determines a repetition duration of each of the plurality of repetitions based on the plurality of available symbols for the physical channel,
wherein all of the allocated symbols are not always available symbols.
