Problems solved by technology

[0007] The problem addressed by the present invention is that in the existing millimeter wave system, there is no suitable signaling and process for the terminal to notify the base station of the beam reciprocity capability, resulting in resource allocation, beam management, and beam correction in the existing multi-beam operating system. The utilization rate and work efficiency of operation resources are relatively low, and new signaling and procedures are required for the notification of the terminal beam reciprocity capability, so as to improve the work efficiency and resource utilization rate of the system

[0051] In this embodiment, a method and device for reporting the beam reciprocity capability of a terminal will be introduced in combination with a specific wireless communication system, wherein the information about the beam reciprocity capability of a terminal is explicitly carried through message 3 in the random access process Information.

[0052] figure 1 It is an interaction process between a base station and a terminal according to the first embodiment of the present invention. figure 1 The wireless communication system includes a terminal 110 and a base station 120 for interactive communication.

[0053] In order to realize the capability of reporting terminal beam reciprocity, the specific process on the terminal side is as follows:

[0054] Step 101: The terminal 110 acquires random access configuration information in a system information block (System Information Block, SIB), including random access channel configuration and preamble resource pool information.

[0090] In the second embodiment, a manner of notifying the beam reciprocity capability will be introduced in combination with a specific wireless communication system, wherein the beam reciprocity capability is notified implicitly through the used random access resources. For example, different beam reciprocity capabilities of terminals are distinguished based on random access channel time-frequency resources or based on random access preamble sequences.

[0091] Figure 5 It is a schematic diagram of a possible resource allocation according to the second embodiment of the present invention, in which different beam reciprocity capabilities of terminals are distinguished by using a resource division method based on random access channel time-frequency resources.

[0092] In a wireless communication system, the parameter N is predefined BC , represents the number of subsets of terminal beam reciprocity capabilities, where N BC ≥1. N BC = 1 means that the system does not dist...

Abstract

The invention provides a random access method and device and a method and device for distributing random access resources. The random access method of a terminal comprises the steps of transmitting amessage 3 containing indication of the beam reciprocity capacity of the terminal if a random access response is successfully detected during the random access; and detecting conflict resolution information so as to complete the random access.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a notification method of terminal beam reciprocity capability. Background technique [0002] With the rapid development of the information industry, especially the growing demand from the mobile Internet and the Internet of Things (IoT, internet of things), it brings unprecedented challenges to future mobile communication technologies. For example, according to the report ITU-R M.[IMT.BEYOND 2020.TRAFFIC] of the International Telecommunication Union ITU, it can be predicted that by 2020, the growth of mobile traffic will increase by nearly 1,000 times compared to 2010 (4G era), and the number of user equipment connections will also increase. It will exceed 17 billion. As massive IoT devices gradually penetrate into mobile communication networks, the number of connected devices will become even more astonishing. In response to this unprecedented chall...
