Abstract
Wireless communications for random access procedures are described. One or more downlink control messages may indicate a system frame number corresponding to a random access preamble. The one or more downlink control messages may indicate the system frame number in a field and/or using a radio network identifier.
Claims18
A method comprising:
- receiving, by a base station, from a wireless device, and via a physical random access channel (PRACH) occasion in a system frame, a preamble;
- transmitting, by the base station, using a radio network identifier associated with the PRACH occasion, a first downlink control message comprising an indication of a system frame number of the system frame;
- receiving, based on the first downlink control message, one or more transport blocks;
- and
- transmitting a second downlink control message, wherein the second downlink control message comprises an indication of a second system frame number different from the system frame number, and wherein one or more second random access responses indicated by the second downlink control message are not for the preamble.
2 more elements
A base station comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, configure the base station to:
- receive, from a wireless device, and via a physical random access channel (PRACH) occasion in a system frame, a preamble;
- transmit, using a radio network identifier associated with the PRACH occasion, a first downlink control message comprising an indication of a system frame number of the system frame;
- receive, based on the first downlink control message, one or more transport blocks;
- and
- transmit a second downlink control message, wherein the second downlink control message comprises an indication of a second system frame number different from the system frame number, and wherein one or more second random access responses indicated by the second downlink control message are not for the preamble.
5 more elements
A non-transitory computer-readable medium storing instructions that, when executed, cause a base station to:
- receive, from a wireless device, and via a physical random access channel (PRACH) occasion in a system frame, a preamble;
- transmit, using a radio network identifier associated with the PRACH occasion, a first downlink control message comprising an indication of a system frame number of the system frame;
- receive, based on the first downlink control message, one or more transport blocks;
- and
- transmit a second downlink control message, wherein the second downlink control message comprises an indication of a second system frame number different from the system frame number, and wherein one or more second random access responses indicated by the second downlink control message are not for the preamble.
