Title: Joint beamforming weights and iq data scaling approach for improved fronthaul
Inventor: LU CHENGUANG
IPC: H04B7/0452
Filed: 2022-03-31
Abstract: A method 1700 is performed by a baseband unit (BBU) 104 for scaling beamforming weights (BFWs) to assist a Radio Unit (RU) 102 with beamforming. The method includes obtaining 1702 a plurality of frequency-domain BFWs for beamforming of a number of downlink data streams in frequency-domain to be transmitted to at least one wireless device via a plurality of antennas. The BBU scales 1704 the plurality of frequency-domain BFWs based on at least one scaling factorand compresses 1706 the plurality of scaled frequency-domain BFWs. The BBU transmits 1708, to the RU, the scaled frequency-domain BFWs that have been compressed. The BBU also determines 1710 at least one user plane scaling factor for frequency-domain user plane IQ data, scales 1712 the frequency-domain user plane IQ data based on the user plane scaling factors, and transmits 1714 the scaled frequency-domain user plane IQ data to the RU.

Abstract: The present invention relates to a biological particle sorting channel and a microfluidic chip. The biological particle sorting channel comprises a first channel unit, which comprises a first side wall and a second side wall disposed oppositely, wherein the first side wall and the second side wall are asymmetric curved surfaces, and the side of the first channel unit close to the first side wall or the second side wall is provided with a deepened channel in a recessed manner that is disposed in an extension direction of the first channel unit. The first channel unit having the asymmetric curved surface is provided to form a focused flow, and the deepened channel is disposed in the extension direction of the first channel unit to disrupt the flow state of the liquid in the vicinity of the first channel unit close to the deepened channel so as to change the inertial lift force and the Dean drag force and thus destroy the original equilibrium such that particles, such as white blood cells, on the side close to the deepened channel can be in a disordered motion state, preventing a band of aggregation of white blood cells from overlapping with circulating tumour cells, which is conducive to the recovery of circulating tumour cells.
