Abstract: A device includes a gate electrode and a gate dielectric surrounding the gate electrode. The gate electrode surrounds a nanostructure. The nanostructure includes stacked nanosheets. The gate dielectric is formed by a high-k (HK) material. The HK material covers sidewalls of the gate electrode in a direction aligned to adjacent devices. Portions of the HK material are recessed from the sidewalls and refilled by a dielectric material with a dielectric constant less than the HK material and an electrical isolation capability greater than the HK material. Replacing the HK material over the sidewalls of the gate electrode with the dielectric material enhances electrical isolation between the gate electrode with adjacent contacts. Consequently, it can reduce electrical leakage between metal gate (MG) contacts and metal-to-device (MD) contacts in scaled transistors of an integrated circuit (IC).

In some other aspects, each AP in a multi-AP environment may be mapped to a respective time sector based on attributes associated with the multi-AP environment so that communications between an AP and its associated STAs can only occur within the respective time sector(s) to which the AP is mapped.

The preamble sending method includes sending a preamble containing two or more code pattern sequences, where the two or more code pattern sequences comprise a first code pattern sequence and a second code pattern sequence. That is, by enabling the preamble to support different code pattern sequences, the rapid transmission of the preamble is implemented by using functions corresponding to the different code pattern sequences, and thus the rapid equalization convergence can be performed after the rate of a passive optical network is improved, thereby improving the transmission efficiency and decreasing the processing delay. Through the preceding technical solutions, the problems in the related art that equalization time is long, transmission efficiency is reduced and processing delay is increased due to the fact that a preamble is not conducive to the convergence of an equalizer are solved.
