Method and apparatus of indicating aggregation number in a wireless communication system

Abstract

A User Equipment (UE) receives a message including a first parameter indicative of a list of entries associated with time resource allocation for multiple PUSCHs. The list does not include a third parameter for configuring a number of repetitions. The UE does not expect the message to include a second parameter that configures and/or indicates an aggregation factor. The UE receives a Downlink Control Information (DCI) indicative of a first entry in the list. The UE performs one or more transmissions on one or more time occasions. A number of time occasions of the one or more time occasions is based on a number of time resource allocations of the first entry.
