Frame structure signaling for multefire
First Claim
1. A method of wireless communication, comprising:
- receiving a downlink (DL) control message using a shared radio frequency spectrum band;
identifying downlink control information (DCI) of the DL control message;
identifying a control channel type of the DL control message from a plurality of control channel types, the plurality of control channel types comprising a first control channel type and a second control channel type;
determining a function of the DL control message based at least in part on the DCI, wherein the function of the DL control message comprises at least one of an uplink transmission trigger or a frame structure indication;
determining an uplink (UL) transmission based at least in part on the function of the DL control message;
determining a starting time for the determined UL transmission based at least in part on the control channel type being of the first control channel type or the second control channel type, wherein the first control channel type corresponds to the starting time being a first starting time at a first time resource and the second control channel type corresponds to the starting time being a second starting time at a second time resource; and
transmitting the UL transmission starting at the determined starting time.

Abstract
Methods, systems, and devices for wireless communication are described. A downlink control message type used for triggering uplink transmissions may convey additional information, including timing for uplink transmissions. The type or format of the control channel (e.g., physical downlink control channel (PDCCH) type or format) used to trigger an uplink transmission may also indicate a starting time or a time period, or both for the uplink transmission. In some cases, downlink control information (DCI) may indicate the function of a downlink control message that includes the DCI. Additionally, system information identified in a downlink control message may be used to determine a subframe length which, in some examples, may be used to determine whether or how long to monitor a discovery reference signal (DRS) subframe.
