Problems solved by technology

[0003] However, for broadcast channels such as synchronization information and system information, it is necessary to ensure that terminals located at various locations in the cell can receive the information. The beamforming technology based on single beam cannot guarantee the initial accuracy of broadcast channels such as broadcast channels due to the narrow beam width. Access control channel coverage

Embodiment 1

[0096] This embodiment provides an information transmission method, which is applied to a terminal, such as figure 2 As shown, the method includes the following steps:

[0097] Step 201: receiving first information sent by the base station in a multi-beam-based manner;

[0098] Here, the multi-beam-based manner may be beam scanning.

[0099] The first information may include first system information and / or synchronization information.

[0100] Wherein, the first system information may be referred to as basic system information, and may include: system bandwidth, random access configuration, and other basic system information required by terminals in idle state, and / or measurement and handover configuration required by terminals in connected state Wait.

[0101] The synchronization information is the information that needs to be received first before the terminal accesses the system. It is used for the terminal to obtain the system timing and is received before the basic sy...

Embodiment 2

[0193] In order to implement the method in Embodiment 1 of the present invention, this embodiment provides a terminal, such as Figure 8 As shown, the terminal includes:

[0194] The first receiving unit 81 is configured to receive first information sent by the base station in a multi-beam-based manner; the first information includes at least first system information and / or synchronization information;

[0195] The first acquiring unit 82 is configured to acquire second information of the base station when transmitting in a multi-beam-based manner; the second information represents optimal transmit beam information when transmitting in a multi-beam-based manner;

[0196] The first determining unit 83 is configured to use the second information to determine the reporting resources required for reporting the request information in the reserved resources;

[0197] The reporting unit 84 is configured to use the determined reporting resource to report the request information to th...

Abstract

The present invention discloses an information transmission method, comprising: a terminal receives first information sent by a base station in a multi-beam-based manner; the first information includes first system information and / or synchronization information; The second information when transmitting in beam mode; the second information represents the optimal transmission beam information when transmitting in a multi-beam mode; using the second information, determine the information required to report the request information in the reserved resources Reporting resources; using the determined reporting resources to report the request information to the base station; the request information is used to request the base station to send corresponding third information. The invention also discloses a terminal and a base station at the same time.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to an information transmission method, a terminal and a base station. Background technique [0002] Through beamforming, a wider, narrower, and more energy-concentrated beam can be obtained, thereby increasing the transmission distance of the signal. In a Long Term Evolution (LTE, Long Term Evolution) system, the beamforming technology has been used in the transmission of a user-specific data channel, so as to improve the coverage of the data channel. [0003] However, for broadcast channels such as synchronization information and system information, it is necessary to ensure that terminals located at various locations in the cell can receive the information. The beamforming technology based on single beam cannot guarantee the initial accuracy of broadcast channels such as broadcast channels due to the narrow beam width. Access control channel coverage. The basic multi-...
