Abstract

For scheduling transmissions of data channels, control channels, or random access channels using downlink control information (DCI) formats, a DCI format can configure a transmission of one or multiple data channels over respective one or multiple transmission time intervals. A first DCI format can configure the parameters for a channel transmission and a second DCI format can trigger the channel transmission and indicate respective one or more transmission time intervals.

6. The UE of claim 1 , wherein the DCI format includes a field indicating a time offset between a time of the PDCCH reception and a time of the first PUSCH transmission.

7. The UE of claim 1 , wherein:

the DCI format includes a field triggering a channel state information (CSI) report,

the transmitter is further configured to transmit the CSI report in a second PUSCH.

8. A base station, comprising:

a transmitter configured to transmit:

the DCI format schedules reception of n PUSCH ≥1 physical uplink shared channels (PUSCHs) up to a maximum of N PUSCH PUSCH receptions;

an encoder configured to encode the DCI format, wherein the DCI format includes:

a hybrid automatic repeat request (HARQ) process number field that indicates a HARQ process number n HARQ from a maximum of N HARQ HARQ process numbers, wherein,

the HARQ process number n HARQ applies for a first PUSCH reception, and

when n PUSCH >1, a HARQ process number (n HARQ +j−1)mod N HARQ applies for a j-th PUSCH reception, wherein 1<j≤n HARQ ,

a redundancy version (RV) field, wherein

when n PUSCH =1, the RV field includes two bits for the PUSCH reception, and
