Abstract: New radio (NR) unlicensed (NR-U) multi-channel access is disclosed for low-radio frequency (RF)-capable user equipment (UE). A base station may enable multi-channel access when single operator operations cannot be guaranteed within a shared communication spectrum. The primary and secondary channels are defined within the shared communication channel. The base station may then transmit a configuration message to one or more low-RF UEs that identifies the charnels and directs the UEs to monitor the primary channel for a successful listen before talk (LBT) indicator. The base station performs an LBT procedure on the primary channel and the secondary channel and signals the low-RF UEs to re-tune to the secondary channel for communication during a current transmission opportunity.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may monitor sets of decoding candidates over a search space in each monitoring occasion to detect downlink control transmissions. Such a monitoring process may be resource intensive. To reduce the processing power involved in monitoring the control channel, a UE may measure resources associated with the downlink control channel to obtain a quality metric. The UE may compare the quality metric to one or more thresholds and may perform a decoding process on a set of configured decoding candidates for the downlink control channel based on the comparing. In some cases, if the channel quality is relatively good, the UE may perform a list decoding process using a list size less than a maximum list size or may perform partial data tone processing to reduce the processing complexity for some of the decoding candidates.
