Semi-persistent scheduling in a wireless network
A wireless device receives, one or more radio resource control messages comprising first periodic resource allocation configuration parameters comprising a first periodicity parameter of a first periodic resource allocation. Downlink control information indicating activation of the first periodic resource allocation is received. The downlink control information comprises one or more first fields. A plurality of transport blocks are transmitted via radio resources associated with the first periodic resource allocation. A time interval between two subsequent transmission occasions of the first periodic resource allocation is based on the one or more first fields and the first periodicity parameter.
