Beam information acquisition method and report method, network side device and terminal

Abstract

The embodiment of the invention discloses a beam information acquisition method and report method, a terminal and a network side device. The beam information acquisition method comprises a step of sending configuration information to the terminal and receiving beam information reported by the terminal based on the configuration information. The configuration information includes at least one of areport type identifier, a report offset, an information report identifier and a beam quality report switch identifier. According to the beam information acquisition method and report method, the terminal and the network side device disclosed in the embodiment of the present invention, the information required by a base station can be reported in a targeted manner according to the configuration information, thus the report of unnecessary information is avoided, and channel overhead is saved. On one hand, a discovery and / or detection result of a transmission beam transmitted by a network side acquisition terminal is satisfied, on the other hand, the further deterioration of a channel condition caused by the beam information or the further load increase of the network side device can be reduced as much as possible.

Description

technical field

[0001] The present invention relates to the field of wireless communication, in particular to a beam information acquisition method and reporting method, network side equipment and a terminal. Background technique

[0002] With the development of communication technology, the nodes on both sides of the communication will communicate through beamforming. Before performing communication, both communicating parties need to determine which beam to use for subsequent communication. In order to solve this problem, usually the user equipment (User Equipment, UE) in both communication parties is also called a terminal, which will measure the transmission beam of the base station, and then manage which beam to use for subsequent communication through the beam management between the terminal and the base station. However, in the prior art, on the one hand, there is no unified beam information reporting scheme; on the other hand, there is a problem that reporting signa...

example 1

[0163] The beam quality information acquisition method provided in this example may be a method applied to beam information of downlink beams in downlink beam management.

[0164] Figure 5 A schematic diagram of downlink beam management provided for this example, including:

[0165] Phase 1: The UE measures different transmit and receive beam node (Transmission and Reception Point, TRP) beams to determine the TRP transmit beam and the UE receive beam.

[0166] Phase 2: The receiving beam of the UE remains unchanged, and the transmitting beam within the TRP and / or between TRPs is changed for the UE to measure different TRP transmitting beams.

[0167] Phase 3: The beam sent by the TRP remains unchanged, and the receiving beam of the UE is changed, which is used for the UE to measure different UE receiving beams. In this example, the TRP may refer to a beam transmitting node such as a base station that transmits a beam to a terminal.

[0172] Such as Image 6 As shown, this example provides a beam quality information processing method, including:

[0173] Step S1: the base station acquires configuration information; the configuration information is any configuration information provided in the foregoing embodiments. For example, the configuration information may include: one or more of a report type identifier, a report offset, an information report identifier, and a beam quality report switch identifier. Certainly, the configuration information may also include: one or more of reporting time type identifier, reporting period indication, reporting bandwidth identifier, sending resource group identifier, sending resource identifier, receiving resource group identifier and receiving resource identifier.

[0174] Step S2: the base station sends the configuration information to the terminal, for example, sends the configuration information through RRC signaling or DCI or MAC layer CE.

[0175] Step S3: The ter...

example 3

[0180] Such as Figure 7 As shown, this example provides a method for reporting beam information, including:

[0181] Step S21: The TRP can carry the configuration parameters related to the beam group or beam reporting with a long change period through the NR RC signaling, such as: beam reporting type, reporting period, and reporting bandwidth.

[0182] The TRP can also report related configuration parameters through the NR MAC layer CE or the NR DCI on the New Radio Physical Downlink Control Channel (New RadioPhysical Downlink Control Channel, NR-PDCCH) carrying a beam group or beam with a shorter change cycle, such as: Send resource identification, etc.; for beam measurement and reporting on the UE side.

[0183] Therefore, in this example, the configuration information sent by the TRP to the terminal can be sent separately, and is not limited to one-time sending.

[0184] In this example, the corresponding bearer signaling is selected according to the change rate of the c...
