Abstract: Aspects described herein relate to communicating a demodulation reference signal (DMRS) corresponding to a downlink control channel, buffering, based on receiving the DMRS, samples of a downlink data channel associated with the downlink control channel, and processing, during on a time period indicated based at least in part on a sequence of the DMRS, at least a portion of the samples of the downlink data channel. Another aspect relates to determining, based at least in part on a sequence of the DMRS, a time offset from the downlink control channel to a downlink data channel, and determining, based at least in part on the time offset, a time period based on which to transmit or start processing samples of the downlink data channel.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for mitigating timing resolution limitations due to synchronization signal blocks (SSBs) with low subcarrier spacing (SCS). An example method by a user equipment (UE) generally includes detecting a SSB; determining a start time of a control resource set (CORESET) associated with the detected SSB, wherein the start time of the CORESET is aligned with a boundary of a symbol having a larger cyclic prefix (CP) than one or more other symbols in a same half-subframe; and monitoring the CORESET for a physical downlink control channel (PDCCH) transmission.

Abstract: Methods, apparatuses, and computer-readable medium for fronthaul compression are provided. An example method may include receiving, from a UE, uplink data via one or more active tones of a plurality of tones in a symbol, the uplink data corresponding to an access vector. The example method may further include compressing the uplink data based on a linear transformation of a pseudo-access vector generated based on the access vector, the linear transformation including a matrix, the compression enabling a second network entity to decompress the compressed uplink data without knowing one or more locations associated with the one or more active tones. The example method may further include transmitting, to the second network entity, the compressed uplink data.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless devices may support a prediction capability for prediction-based control information. A first device may receive, from a second device, first control signaling that activates the predication capability of the first device to generate a set of one or more control parameters for communications. The second device may transmit second control signaling to the first device to indicate initial values of the control parameters and a channel condition model for the first device. The first device and the second device may generate a set of multiple values associated with the control parameters over a time period based on the initial values of the control parameters and the channel condition model. The first device and the second device may communicate during at least the time period according to the set of generated values associated with the control parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify, for a user equipment (UE), a configuration for receiving a set of downlink control information (DCI) messages on one or more layers of a set of layers of a downlink shared channel. The base station may transmit, to the UE, a first DCI message in a downlink control channel, where the first DCI message may schedule resources of the downlink shared channel for the set of piggybacking DCI messages. The UE may receive the first DCI message and identify the configuration for receiving the set of DCI messages on the one or more layers of the downlink shared channel. The UE may receive, from the base station, the set of DCI messages on the one or more layers of the downlink shared channel based on the identified configuration.
