Traffic type based scheduling in a wireless network and device
A wireless device receives at least one message. The at least one message may comprise: an uplink radio network temporary identifier (RNTI) for a periodic resource allocation, and at least one configuration parameter for the periodic resource allocation. The at least one configuration parameter may comprise: an uplink interval parameter, and at least one first parameter indicating one or more traffic types. A downlink control information (DCI) corresponding to the uplink RNTI may be received. The DCI may indicate activation of the periodic resource allocation. At least one transport block comprising data of the one or more traffic types may be transmitted employing the at least one configuration parameter.

6. The method of claim 1 , wherein the at least one configuration parameter further comprises at least one of:
a number of configured hybrid automatic repeat request (HARQ) processes; or at least one transmit power parameter.
7. A method comprising:
transmitting, by a base station, at least one radio resource control (RRC) message comprising:
an uplink radio network temporary identifier (RNTI) for a periodic resource allocation; and
at least one configuration parameter for the periodic resource allocation, the at least one configuration parameter comprising:
an uplink interval parameter; and
at least one first parameter indicating that the periodic resource allocation is for data associated with at least one logical channel identifier;
receiving, by the base station from a wireless device, assistance information comprising:
the at least one logical channel identifier for uplink periodic traffic; and
a message size for the uplink periodic traffic;
transmitting, based on the assistance information, a downlink control information (DCI) corresponding to the uplink RNTI, the DCI indicating activation of the periodic resource allocation; and
receiving, by the base station, at least one transport block comprising the data associated with the at least one logical channel identifier;
wherein the assistance information further comprises a traffic type for the uplink periodic traffic, wherein the traffic type comprises voice traffic and vehicle communication services traffic.
8. The method of claim 7 , wherein the at least one first parameter comprises the at least one logical channel identifier.
9. The method of claim 7 , further comprising transmitting a second DCI corresponding to the uplink RNTI, the second DCI releasing the periodic resource allocation.
10. The method of claim 7 , wherein:
the at least one RRC message further comprises a periodic resource allocation configuration index for the at least one configuration parameter, and the DCI comprises the periodic resource allocation configuration index; or
the DCI comprises at least one resource parameter; the transmitting, the at least one transport block, further employs the at least one resource parameter; and the at least one transport block is transmitted in a subframe determined employing the uplink interval parameter.
11. The method of claim 7 , wherein the at least one configuration parameter further comprises at least one of:
a number of configured hybrid automatic repeat request (HARQ) processes; or at least one transmit power parameter.
12. A wireless device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
receive, from a base station, at least one radio resource control (RRC) message comprising:
an uplink radio network temporary identifier (RNTI) for a periodic resource allocation; and
at least one configuration parameter comprising:
an uplink interval parameter; and
at least one first parameter indicating that the periodic resource allocation is for data associated with at least on logical channel identifier;
transmit, to a base station, assistance information comprising:
the at least one logical channel identifier for uplink periodic traffic; and
