Abstract: The present disclosure relates to transmitting and receiving an improved wake-up signal (WUS) by grouping user equipment (UE). A base station may group and assign a plurality of UEs into UE groups. The base station can then determine and transmit a WUS identifying certain UEs to wake-up for a paging occasion (PO). The UEs can listen for their corresponding WUS. After receiving the WUS, the UEs can wake-up for the PO. The base station can also determine the total amount of different UE groups. Within each group, there can be both legacy and updated UEs, wherein each legacy UE receives the same legacy WUS and the updated UEs receive a group-specific WUS. The base station can also balance the amount of legacy and updated UEs within each group based on different factors. Also, each WUS can be turned on or off, which can be carrier specific.

Abstract: Methods, systems, and devices for wireless communications are described. A network may be configured to provide a beam measurement configuration to a UE that indicates durations for monitoring transmission beams, and tuning a component of the UE between the monitoring. The durations may include a first portion that a UE may use for a tuning operation and a second portion that the UE may use to monitor for or measure a respective reference signal. In various examples, the indicated durations may include a third portion that the UE may use for another tuning operation, or the durations may overlap with one another during an overlap duration that the UE may use for another tuning operation. During the indicated durations, the network may refrain from transmitting other downlink data or control information for the UE, and the UE may refrain from monitoring for such other downlink data or control information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use easily detectable transmission parameters to infer difficult-to-detect parameters for communications with a base station. For example, the base station may provide the UE with multiple sets of transmission parameters, and the UE 115 may choose from among these sets of transmission parameters for the communications. In some cases, the UE may be configured with a reference set of transmission parameters, receive one or more transmission parameters that are different relative to the reference set of transmission parameters, and then determine to use the different transmission parameters for the communications. Additionally or alternatively, the multiple sets of transmission parameters may be specified for a certain uplink message (e.g., random access channel messages), where the UE selects the transmission parameter set based on one or more characteristics of the uplink message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may activate or release one or more semi-persistent scheduling (SPS) configurations for group-common downlink shared channels based on signaling from a base station. For example, the UE may receive downlink control information (DCI) from the base station that includes a feedback process field, where a value of the feedback process field indicates at least one of one or more SPS configurations is to be activated. In some examples, the base station may transmit the DCI in a group-common downlink control channel or in a UE-specific downlink control channel. Additionally, the base station may transmit a deactivation message to the UE to indicate for the UE to release one or more activated SPS configurations, where the deactivation message is transmitted in a group-common downlink control channel or a UE-specific downlink control channel.
