Abstract

A wireless device may receive a radio resource control message comprising first configuration parameter(s) of a configured periodic grant of a first type. The first configuration parameter(s) may indicate: a timing offset and a symbol number that identify a resource of an uplink grant of the configured periodic grant; a first periodicity of the configured periodic grant, the first periodicity indicating a time interval between two subsequent resources of the configured periodic grant; and one or more demodulation reference signal parameters of the configured periodic grant. The configured periodic grant may be activated in response to the radio resource control message. Symbol(s) of the resource of the uplink grant of the configured periodic grant may be determined based on the timing offset, the symbol number, and the first periodicity. Transport block(s) may be transmitted, via the resource, employing the demodulation reference signal parameter(s).

A method comprising:

receiving, by a wireless device, a radio resource control message comprising one or more first configuration parameters of a configured periodic grant of a first type, wherein the one or more first configuration parameters indicate:
a timing offset and a symbol number that identify a resource of an uplink grant of the configured periodic grant of the first type;
a first periodicity of the configured periodic grant of the first type, the first periodicity indicating a time interval between two subsequent resources of the configured periodic grant of the first type;
and
one or more demodulation reference signal parameters of the configured periodic grant of the first type;
activating the configured periodic grant in response to the radio resource control message;
determining one or more symbols of the resource of the uplink grant of the configured periodic grant of the first type based on the timing offset, the symbol number, and the first periodicity;
and
transmitting, via the resource, one or more transport blocks employing the one or more demodulation reference signal parameters.
