Macro and micro discontinuous transmission
Methods, systems, and devices for wireless communication are described. A wireless device may receive during an active duration, an indication of an opportunity to request uplink (UL) transmission. The wireless device may identify an opportunity to request UL transmission based at least in part on the indication. In some cases, the active duration may be a discontinuous transmission (DTX) configuration. The wireless device may then transmit on the UL resources during the opportunity to request UL transmission.
