Abstract: Systems, methods, and devices for secondary cell activation using temporary reference signals are provided. In one aspect, a method of wireless communication performed by a user equipment (UE), includes receiving, from a base station (BS) via a first cell, an activation command to activate a second cell different from the first cell, and receiving, from the BS via the second cell during an activation period, a first reference signal different from a synchronization signal block (SSB). The method further includes performing a measurement of the first reference signal, and operating in the second cell based on the measurement. In some aspects, using reference signals different from SSBs may reduce the delay associated with activating the secondary cell.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication between a user equipment (UE) and a base station. The UE monitors for a wake-up signal (WUS) within a WUS monitoring window based on a jitter monitoring window associated with jittered data traffic at a base station. The base station transmits, to the UE, the WUS. The UE determines whether the WUS is received within the WUS monitoring window. The UE detects a semi-persistent scheduling (SPS) occasion following a location of the WUS by an offset based on the WUS being received within the WUS monitoring window. The base station transmits, to the UE, in the SPS occasion following the WUS by the offset, a physical downlink shared channel including a data frame of the jittered data traffic.

The UE may receive downlink control information (DCI) activating at least one SPS configuration, of the first SPS configuration and the second SPS configuration. The UE may perform the communication using the at least one activated SPS configuration. Numerous other aspects are described.

Abstract: A method of wireless communication for a user equipment (UE) includes entering a dormancy period for a secondary cell group (SCG) of a base station (BS) during which no downlink (DL) data or control transmissions are received from the SCG; performing a channel state information (CSI) measurement on the SCG during the dormancy period to generate a measurement report; determining an uplink (UL) beam of a primary secondary cell (PSCELL) of the SCG; transmitting the measurement report to the BS on the UL beam of the SCG; and determining, during the dormancy period and after transmitting the measurement report, one or more downlink (DL) beams for communicating on the SCG based on one or more rules and based on the measurement report, wherein the one or more rules result in the BS determining the same one or more DL beams based on the measurement report.

Abstract: Methods, systems, and devices for time domain single carrier (SC) waveform communications are described. A user equipment (UE) may generate an SC waveform by resampling (e.g., up-sampling) mapped information bits prior to insertion of a cyclic prefix (CP) or guard interval (GI). Performing resampling prior to CP/GI insertion allows for resource allocation flexibility and a base station may allocate resources for the SC waveform in accordance with this flexibility. For example, a base station may not be limited or restricted to a certain number of resources for SC waveform communications and may therefore determine a resource allocation for the UE based on the capability of the UE to perform resampling prior to CP/GI insertion. The resampling may be performed according to a set of parameters including a resampling ratio, which may be indicated to the UE via control signaling (e.g., from the base station).

The UE may disconnect from the set of source CGs after connecting to the set of target CGs. Numerous other aspects are provided.

Abstract: A base station transmits an indication of a configuration indicating one or more time-variable parameters for a group-specific wake-up signal (WUS) to an associated group of user equipment (UEs). The base station determines a value of the one or more time-variable parameters based on a time associated with the group-specific WUS and transmits the group-specific WUS to the group of UEs based on the determined value. A UE in the group of UEs receives the indication of the configuration from the base station and determines a value of the one or more time-variable parameters based on a time associated with the group-specific WUS. The UE monitors for the group-specific WUS based on the determined value.
