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 first network node may receive second phase tracking reference signal (PTRS) configuration information for a second PTRS that is associated with a second network node. The first network node may transmit a physical downlink shared channel (PDSCH) that includes a first PTRS that is based at least in part on first PTRS configuration information, the PDSCH being based at least in part on cross-PTRS rate matching and the second PTRS configuration information. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for reducing a quantity of data sent carrier aggregation (CA) related capability reporting by a UE operating in a cell using full dimension multiple-input multiple-output (FD-MIMO) techniques. In an exemplary method, a base station obtains a relative weight of baseband processing for a component carrier (CC) configured for full-dimension multiple-input multiple-output (FD-MIMO) communications for a user equipment (UE); determines, based on the relative weight, to enable FD-MIMO downlink (DL) transmissions to the UE via the CC; and transmits an FD-MIMO transmission via the CC to the UE.

Abstract: A method for wireless communication by a network node includes transmitting a first group of frames comprising a group of normal slots and one or more first special slots. The method also includes reconfiguring one or more second special slots within a second group of frames scheduled after the first group of frames based on a block error rate (BLER) associated with the group of normal slots failing to satisfy a BLER condition. The method further includes transmitting the second group of frames based on reconfiguring the one or more second special slots within the second group of frames.

Abstract: The present disclosure presents methods and apparatuses for enhanced received signal processing using signal-based channel impulse response (CIR) estimation. For example, according to an example method presented herein, a user equipment (UE) or a component therein may receive a signal corresponding to a transmitted signal sent by a network entity, wherein the transmitted signal comprises at least a data channel, estimate chip contents of the transmitted signal, based on the received signal including the data channel, to obtain estimated chip contents, and compute an estimated channel impulse response (CIR) based on at least the estimated chip contents. Based on this estimated CIR, the UE may thereafter reprogram a received signal reconstruction filter, perform interference cancelation procedures, and/or adjust one or more equalizer taps. By performing such functions, the UE may exhibit improved communication characteristics and enable a more robust user experience.
