Problems solved by technology

Although beam refinement can be performed step by step, it is difficult to determine the measurement under other independent paths
In this case, on the one hand, it will limit the beam training for other paths, and choose backup paths or effective space division multiplexing; on the other hand, in the data transmission stage, once the path is blocked, it is difficult to retrain other paths so that To achieve uninterrupted data transmission
[0006] A beam scanning scheme for multiple independent paths that solves the above technical problems has not been given in the related art

Embodiment 1

[0196] The present application provides a beam scanning and switching method, which is applied to a transmitting end of a reference signal. The M beam grouping sequence number flags are used to instruct the receiving end of the reference signal to perform one or more of the following:

[0197] switching the beams of the control channel and / or the data channel to the corresponding beam grouping;

[0198] Beam scanning under the corresponding beam grouping;

[0199] Channel quality measurement under the corresponding beam grouping;

[0200] Channel quality feedback under the corresponding beam grouping.

[0201] In some implementation manners, before notifying the receiving end of the M beam grouping sequence number indications, the method may further include: performing beam grouping to obtain a grouping result, where the grouping result includes the M beam grouping sequence number indications.

[0202] In some implementation manners, before notifying the receiving end of the ...

Embodiment 2

[0264] This embodiment provides a method for beam scanning and switching, which is applied to a receiving end of a reference signal, including:

[0265] The receiving end uses the M beam grouping sequence numbers to indicate the corresponding beam groupings, and performs one or more of the following:

[0266] switching the beams of the control channel and / or the data channel to the corresponding beam grouping;

[0267] Beam scanning under the corresponding beam grouping;

[0268] Channel quality measurement under the corresponding beam grouping;

[0269] Channel quality feedback under the corresponding beam grouping;

[0270] The sequence numbers of the M beam groupings are indicated by the transmitting end of the reference signal to the receiving end, and the M is an integer greater than or equal to 1.

[0271] In some implementations, the receiving end feeds back acknowledgement information to the transmitting end using one of the following beam groupings:

[0272] Beari...

Embodiment 3

[0304] This embodiment provides a response method, applied to a terminal, including:

[0305]The terminal receives the signaling sent by the base station, generates the first effective time of the signaling, and sends the first effective time to the base station; wherein, the signaling carries M number of beam group sequence number indications, and the M is an integer greater than or equal to 1, and the M beam group sequence number flags are used to instruct the terminal to perform one or more of the following: switch the beam of the control channel and / or the data channel to the corresponding beam group; beam scanning; channel quality measurement under the corresponding beam grouping; channel quality feedback under the corresponding beam grouping.

[0306] Wherein, the effective time includes: #1 takes effect immediately; #2 is in K time units, where K is an integer greater than or equal to 0.

[0307] In some implementations, the signaling may be beam measurement signaling,...

Abstract

This paper discloses a method and device for beam scanning and switching, which are applied to a transmitting end of a reference signal, including: the transmitting end notifying the receiving end of M number of beam grouping sequence numbers, where M is an integer greater than or equal to 1, The M beam grouping sequence number marks are used to instruct the receiving end of the reference signal to perform one or more of the following: switch the beam of the control channel and / or the data channel to the corresponding beam grouping; the beam scanning under the corresponding beam grouping; the corresponding beam Channel quality measurement under grouping; channel quality feedback under corresponding beam grouping. The transmitter and receiver can perform beam training and channel quality measurement for the transmit and receive beams under a specific independent path.

Description

technical field [0001] The present application relates to the field of communications, and in particular, to a method and apparatus for beam scanning and switching. Background technique [0002] The ultra-wide bandwidth high frequency band (ie millimeter wave communication) has become an important direction for the development of mobile communication in the future, attracting the attention of academia and industry around the world. In particular, with the increasingly congested spectrum resources and a large number of physical network accesses, the advantages of millimeter waves become more and more attractive, and many standards 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 an important innovation point of 5G NewRadio Access Technology (New RAT) by virtue of its significant advantages of large bandwidth. [0003] However, high-frequency communica...
