1. A method performed by a user equipment (UE) for selective transmission or reception of a signal or channel with a wireless network, the method comprising:
receiving a first physical downlink control channel (PDCCH) transmission from the wireless network; and
without determining whether a signal or channel is scheduled for the UE during a first duration immediately following the first PDCCH transmission, refraining from transmitting or receiving any signals or channels during the first duration, wherein the first duration is based on one or more of the following:
one or more predicted scheduling characteristics for the PDCCH;
one or more UE operating conditions; and
one or more communication characteristics of an application running on the UE;
wherein the one or more predicted scheduling characteristics for the PDCCH include one or more of the following predicted minimum offsets:
a first predicted minimum offset between a PDCCH transmission and physical downlink shared channel (PDSCH) transmission scheduled by the PDCCH transmission;
a second predicted minimum offset between a PDSCH transmission, scheduled by the PDCCH transmission, and a subsequent physical uplink control channel (PUCCH) transmission;
a third predicted minimum offset between a PDCCH transmission and physical uplink shared channel (PUSCH) transmission scheduled by the PDCCH transmission;
a fourth predicted minimum offset between a PDCCH transmission and a downlink reference signal (RS) scheduled by the PDCCH transmission; and
a fifth predicted minimum offset between a PDCCH transmission and a uplink sounding reference signal (SRS) scheduled by the PDCCH transmission.
