In one example method, an access network device sends a plurality of pieces of time division multiplexing mode information to a terminal, where each of the plurality of pieces of time division multiplexing mode information indicates one time division multiplexing mode, and in the time division multiplexing mode, time division multiplexing is performed on a first uplink time domain resource and a second uplink time domain resource, the first uplink time domain resource is an uplink time domain resource of a first carrier, and the second uplink time domain resource is an uplink time domain resource of a second carrier. The access network device sends first information to the terminal, where the first information activates one of the plurality of time division multiplexing modes indicated by the plurality of pieces of time division multiplexing mode information.

Resource configuration method and communication apparatus

The present disclosure relates to time domain resource configuration methods and access network devices One example method includes determining a guard period (GP) resource required by a terminal device, where the GP resource required by the terminal device is a GP resource required by the terminal device for uplink synchronization with an access network device, and sending first time domain resource configuration information to the terminal device, where the first time domain resource configuration information indicates the GP resource required by the terminal device.

Time domain resource configuration method and access network device

An indication method includes: receiving, by a terminal device, configuration information sent by a network device, where the configuration information includes at least two of a subcarrier configuration parameter, a time parameter of a first period, and a total quantity of slots included in the first period; and determining, by the terminal device based on the configuration information, information about a second period within which the terminal device performs data transmission by using a bandwidth part BWP. The network device may notify the terminal device of a plurality of SCSs supported by a cell and period information corresponding to the SCSs. The terminal device may determine information about a period within which data transmission is performed by using the BWP, so that the terminal device transmits data by using the cell.

A method for controllingspp. blooms in harbors includes: designing different sites at equal intervals in an area in spring, collectingofspp. with an I-type trawl net for zooplankton from bottom to surface, determining whether polyps ofspp. inhabit in the vicinity of the sites; seeking large floating substrates that the polyps attach to using scuba diving in the determined habitats of the polyps; dragging the substrates to a shore base and scraping off all organisms attached to bottom surfaces of the substrates in a physical manner, then air drying the substrates for 7 days or more; and applying an antifouling paint on the bottom surfaces of the dried substrates followed by drying, then returning the substrates back to their original sites in the sea to control the bloom ofspp. in the area.

A lithography pupil shaping optical system and method for generating off-axis illumination mode. The invention is composed of illumination mode generation unit, rotatable wave plate, polarization beam splitter unit, ring I generation unit and ring II generation unit. Through selecting corresponding diffractive optical element and appropriate adjustment, this invention can generate various illumination modes including single ring illumination mode and double ring illumination mode. The intensity at pupil plane and the inner and outer diameters of the off-axis illumination mode can be adjusted continuously.
