308 results about "PCell" patented technology

PCell stands for parameterized cell, a concept used widely in the automated design of analog integrated circuits. A PCell represents a part or a component of the circuit whose structure is dependent on one or more parameters. Hence, it is a cell which is automatically generated by electronic design automation (EDA) software based on the values of these parameters. For example, one can create a transistor PCell and then use different instances of the same with different user defined lengths and widths. Vendors of EDA software sometimes use different names for the concept of parameterized cells, e.g. T-Cell and Magic Cell.

Network Energy Saving for Multiple Cells

Techniques for neighbor cell measurement in wireless communications systems

Methods, systems, and devices for wireless communications are described for a user equipment (UE) to report information associated with neighbor cells when one or more of the neighbor cells are operating in an energy saving mode. A serving cell of a network entity, such as a primary cell (PCell) may request a neighbor cell report from a served UE and, if a neighboring cell is in a NES mode, the served UE may provide an indication that the neighbor cell is in the NES mode. The UE 115 in some cases may transmit a demand for an on-demand signal from the neighbor cell, and monitor for the subsequent signal. The UE may transmit the neighbor cell report to the serving cell based on information provided from one or more of the transmissions of the neighbor cell.
