Abstract: Aspects are provided which allow a network entity to consider an identity property for received RS during analog combining or aggregation in order to achieve efficient channel sounding and estimation. The network entity may receive an RS in a time period via a plurality of antenna elements. The network entity may combine, in an analog domain, the RS received via each of the antenna elements based at least in part on weights associated with the antenna elements. At least one weight of the weights changes over the time period, and the weights are elements of a time domain orthogonal cover code or a DFT matrix. As a result of these weights, the network entity may estimate multiple combined or individual channels of antenna elements or groups from one or more RS in one or more symbols, potentially improving UE energy efficiency, efficient resource allocation, and coherency between the antenna elements.

Abstract: Techniques and apparatus for determining a transport block (TB) configuration and hybrid automatic repeat request (HARQ) acknowledgment (ACK)/negative acknowledgment (NACK) configuration for full duplex (FD) UE(s) are described. One technique involves receiving channel state information (CSI) report(s) from a UE operating in FD mode. At least one of a TB configuration or feedback type for a communication slot is determined based on the CSI report(s). The communication slot can include half duplex (HD) symbol(s) and FD symbol(s). An indication of at least one of the TB configuration or the feedback type is signaled to the UE. Another technique involves receiving, from a base station (BS), downlink data transmission(s) across a slot(s). A type of duplexing mode associated with each of the slot(s) is determined. The downlink data transmission(s) are acknowledged, based at least in part on the type of duplexing mode associated with each of the slot(s).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a grant delay request to a base station. The grant delay request may indicate a future time, at or thereafter a base station is requested to allocate resources to the UE. The base station may transmit the uplink grant to the UE allocating the resources to the UE based on the grant delay request, and the UE may transmit, to the base station, an uplink transmission including the uplink data based on the uplink grant. The UE may transmit the grant delay request as part of a scheduling request (SR), or as part of a buffer status report (BSR), or a combination of these.
