This disclosure provides methods, components, devices and systems for enhanced downlink and uplink scheduling based on assistance information related to PDCP status reports. Some aspects specifically relate to a wireless communication system including a disaggregated base station architecture in which a CU provides a DU assistance information related to PDCP status reports from which assistance information the DU may determine appropriate downlink or uplink scheduling start timing for a UE. In some examples, the DU obtains from the CU assistance information indicating an unreceived PDCP SDU at a UE or the CU, and sends downlink data or an uplink grant to the UE based on the assistance information. The CU may deliver the downlink data to the DU prior to sending the assistance information or obtain uplink data from the DU after sending the assistance information. Duplication of PDCP SDU transmissions and unnecessarily extended scheduling delays may thus be minimized.
In some aspects, a network node may transmit access information indicating one or more probability values that are respectively associated with one or more network nodes. The probability values may be selected to “guide” or “steer” one or more UEs to select an anchor node and/or a non-anchor node for communication. As an illustrative example, if a first probability value associated with a first network node is 0.75, and if a second probability value associated with a second network node is 0.25, a UE may select the first network node with a probability of 75 percent and may select the second network node with a probability of 25 percent. In some implementations, an anchor node of the UE may transmit the access information via a system information block of type one (SIB1) that indicates the probability values.
An apparatus for multi-object tracking determines a current representation of a current object in a current image. The apparatus computes a joint Gaussian distribution between the current representation of the current object and a previous representation stored in one or more memory buffers, wherein the previous representation was determined from a previous image. The apparatus updates the one or more memory buffers based on the joint Gaussian distribution. For example, the apparatus determines whether to remove or replace the previous representation in the one or more memory buffers based on values of a covariance matrix of the joint Gaussian distribution.

The processor-based system includes a throttle request accumulate circuit to receive throttle requests, determine a highest or most aggressive throttle value among the throttle requests, and generate a throttle control signal configured to throttle activity in the plurality of processing circuits. Throttle requests have throttle values corresponding to a reduction in activity in at least a portion of the plurality of processing circuits and may correspond to a particular number of cycles of reduced activity in a window of cycles. In addition to reducing response time to local events or conditions compared to waiting for a hierarchical response, the throttle request accumulate circuit accumulates throttle requests from all circuits that adjust or throttle activity in the plurality of processing circuits, and ensures that the net effective throttle controlling activity in the processing circuits at any given time is based on the highest throttle value of those accumulated throttle requests.
A throttle control circuit receives a throttle control signal for controlling power consumption in a plurality of processing segment circuits. The throttle control signal has a throttle control value based on throttle requests from monitoring circuits that have detected power-related events or conditions and correspond to a requested change in activity in the plurality of processing segment circuits. The throttle control circuit receives the throttle control signal in a plurality of throttle administration circuits that each generates a throttle select signal to select an activity control signal for a corresponding processing segment circuit. In each of a first number (N) of consecutive cycles of a clock signal, the activity control signal disables state changes in the corresponding processing segment circuit for a second number (M) of cycles among the first number (N) of consecutive cycles to reduce power consumption in the processing segment circuits.
