Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, information configuring an active bandwidth part (BWP) that does not include a bandwidth associated with one or more of a synchronization signal block (SSB) or a control resource set zero (CS0). The UE may perform, based at least in part on a radio frequency (RF) retune mode, an RF retune to a union bandwidth that covers the active BWP and the bandwidth associated with one or more of the SSB or the CS0. Numerous other aspects are described.

Abstract: To reduce power consumption, a user equipment (UE) may trigger a microsleep in a subframe when a physical downlink control channel (PDCCH) does not include a downlink grant. However, because the microsleep depends on the PDCCH not including a downlink grant, the UE cannot trigger the microsleep until after the PDCCH is decoded. Accordingly, in some aspects, a UE may enable an aggressive extra microsleep in which a microsleep duration may be increased by reducing a PDCCH decode time. For example, a UE may use a stale channel estimate and noise estimate from a previous subframe to perform PDCCH demapping when conditions related to a PDCCH block error rate are satisfied. In this way, removing channel estimation and noise estimation from a PDCCH demapping path may reduce the PDCCH decode time, whereby the UE may trigger a microsleep sooner to increase a sleep ratio and thereby increase power savings.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a scaling factor for a beam failure detection (BFD) evaluation period associated with a secondary cell group of a set of secondary cell groups. The scaling factor may be determined based at least in part on a number of secondary cell groups included in the set of secondary cell groups. In some aspects, the UE may perform a BFD measurement, associated with the secondary cell group, based at least in part on the scaling factor for the BFD evaluation period. Numerous other aspects are provided.

Abstract: A configuration for pre-configuring a UE with a gap configuration for each possible BWP, to allow the UE to only use gaps needed to perform a measurement based on an active BWP of the UE. The apparatus receives a first configuration for one or more BWPs. The apparatus receives a second configuration for one or more gaps for one or more measurements. The apparatus receives an indication of an active BWP from the one or more BWPs. The apparatus determines whether to apply a gap of the one or more gaps based on the active BWP and a measurement to be performed for the one or more measurements.

Abstract: Methods and apparatus are described for performing a cell search procedure. For example, the methods and apparatus may include making multiple signal power measurements over multiple bandwidths on a wideband frequency channel, where the signal power measurements may correspond to a signal received on the wideband frequency channel. Further, the methods and apparatus may further include performing a narrowband rejection procedure based on the signal power measurements, where the narrowband rejection procedure may determine whether the signal power measurements correspond to a narrowband signal or a wideband signal. Moreover, the methods and apparatus may also include continuing a wideband cell search procedure on the wideband frequency channel based on the narrowband rejection procedure determining that the signal power measurements correspond to the wideband signal.

Abstract: A wireless communication network includes a user equipment (UE) to receive a set of instructions, from a base station, to perform a simultaneous change of a set of current bandwidth parts (BWPs) to a set of new BWPs in a set of cells. The set of instructions schedules set of slots for the UE to receive and/or transmit a set of downlink and/or uplink signals via the set of new BWPs, respectively. The UE also determines a delay associated with performing the simultaneous change of the set of current BWPs to the set of new BWPs, respectively, and determines whether it is able to receive and/or transmit the set of downlink and/or uplink signals via the set of new BWPs in the set of slots satisfying the delay, respectively. A base station is also included to communicate with the UE to effectuate the aforementioned operation.
