Embodiment Construction

[0072] Embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0073] The terms "first" and "second" in the embodiments of the present invention are used for description purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features.

[0074] See figure 1 , figure 1 It is a schematic structural diagram of a beam switching system provided by an embodiment of the present invention. The beam switching system includes a base station and a terminal device. Various analog beams are maintained between the base station and the terminal device, and communication is performed through the various analog beams. In addition, the base station can use single-level DCI or two-level DCI to instruct the UE...

Abstract

The embodiment of the present invention discloses a wave speed switching method and related equipment, including: the terminal equipment receives the first subframe sent by the base station through the first beam, and the first subframe includes the first-level downlink control information and the second-level downlink control information. Control information; the terminal device searches for the second-level downlink control information according to the first-level downlink control information, and the first-level downlink control information includes the second-level downlink control information in the first sub-level position indication information in the frame; the terminal device switches from the first beam to the second beam to receive the second subframe according to the found second-level downlink control information, and the downlink control information includes the Handover indication field for the second beam. By adopting the embodiment of the present invention, the flexibility of beam switching is improved, the load balance of the control channel is realized, and the time delay of beam switching is reduced.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a beam switching method and related equipment. Background technique [0002] Beam Forming (BF) technology can achieve higher antenna array gain by spatially oriented in a specific direction, and the use of beam forming technology for transmission in the fifth-generation mobile communication technology (5th-Generation, 5G) is the focus Direction of development. For example, an important research direction in high frequency (High Frequency, HF) communication is analog plus digital hybrid beam forming (Hybrid Beam Forming, HBF), which can not only reduce the loss of high frequency signals due to the transmission distance, but also put The complexity and hardware cost are controlled within an acceptable range. [0003] The analog beamforming can be implemented by using a phase shifter, and the phase of a radio frequency (Radiofrequency, RF) link is adjusted by using th...
