A communications method and apparatus are provided. The method includes: A first terminal side device determines a frequency domain resource of a scheduled first physical downlink shared channel (PDSCH), where the first PDSCH corresponds to a first demodulation reference signal (DM-RS) on a first antenna port; and when the frequency domain resource includes N consecutive frequency domain units, and there is a second DM-RS on a second antenna port in each of L consecutive frequency domain units in the N frequency domain units, determines that precoding of each second DM-RS is the same. The second DM-RS and the first DM-RS are in a same code division multiplexing (CDM) group, the second DM-RS corresponds to a second PDSCH scheduled for a second terminal side device, each N and L is an integer greater than 1, and L is less than or equal to N.

Communications method and apparatus

Disclosed is a combined LED grow lighting system, comprising an LED light track and at least one LED light strip which slidably connects with and longitudinally slides along the LED light track; wherein a remote control signal receiver to receive a remote control signal is configured within the LED light track, a processing device for processing the remote control signal received by the remote control signal receiver to generate a control signal for controlling a power of LED in each LED light strip is connected with each LED light strip, respectively; an LED constant current power supply and a constant current control circuit are configured within the LED light strip, and the constant current control circuit is connected with the processing device and receives the control signal regarding the power of the LED light strip sent from the processing device to control the LED constant current power supply.
