Embodiment 2

[0188] Figure 4 It is a schematic structural diagram of a hybrid precoding transceiver according to an optional embodiment of the present invention, such as Figure 4 As shown, the transmitting end and the receiving end are configured with multiple antenna units and multiple radio frequency channels. Wherein, each radio frequency channel is connected (or partially connected) to the antenna array unit, and each antenna unit has a digital keying phase shifter. By loading the signals on each antenna unit with different phase shifts, the high-frequency band system realizes beamforming on the analog side. Specifically, in a hybrid beamforming transceiver, there are multiple streams of RF signals. Each signal stream loads the antenna weight vector (Antenna Weight Vector referred to as AWV) through the digital keying phase shifter, and is sent from the multi-antenna unit to the high-frequency physical propagation channel; at the receiving end, the radio frequency signal received b...

Abstract

The invention provides a beam information feedback method and device, and a configuration information feedback method and device. The beam information feedback method comprises the following steps: areceiving end receives reference signals sent by a sending end, wherein the reference signals are carried on one or more beams, or each reference signal group is carried on the same beam, and the reference signal group is a reference signal group obtained by dividing the reference signals according to time-frequency code resources; the receiving end obtains the beam sequence number and channel state information according to the reference signal; and the receiving end sends the set containing the beam sequence number and the channel state information to the sending end. The technical scheme provided by the invention solves the problem that the receiving end can not feed back the related characteristics among the beams, so that the sending end can not carry out accurate and flexible data transmission according to the related characteristics of the receiving end, thereby reducing the diversity and multiplex gain of the system; therefore, the diversity and multiplex gain of the system areimproved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a feedback method and device for beam information and configuration information. Background technique [0002] The high frequency band with ultra-wide bandwidth, that is, millimeter wave communication, has become an important direction for the development of mobile communication in the future, attracting the attention of academic and industrial circles around the world. In particular, the advantages of mmWave are becoming more and more attractive in the current increasingly congested spectrum resources and massive access to physical networks. Many standard organizations, such as IEEE and 3GPP, have begun to carry out corresponding standardization work. For example, in the 3GPP standard group, high-band communication will become a 5G New Radio Access Technology (New Radio Access Technology, It is an important innovation point of New RAT for short. [0003] However, there are a...
