Embodiment 1

[0119] The beam configuration information includes: beam indication information, monitoring period indication information and offset indication information. Wherein, the monitoring period indication information is used to indicate the monitoring period. The monitoring period indication information may include but not limited to the value of the monitoring period or the index of the monitoring period. The offset indication information is used to indicate the offset. The offset indication information may include but not limited to the value of the offset or the index of the offset.

[0120] In this embodiment, the base station indicates the monitoring period of the beam to the terminal by indicating the monitoring period of the beam to the terminal, of course, the application is not limited thereto. For example, if the base station and the terminal have agreed in advance or configured the monitoring period of a certain beam through signaling, the beam configuration information...

Embodiment 2

[0175] The beam configuration information includes: beam indication information, monitoring period indication information and search space indication information. Wherein, the search space indication information is used to indicate the search space, which may be an index of the search space, or a time domain index of the search space, or the like. This embodiment may be applicable to a scenario where a base station sends beam configuration information to a terminal, so that the terminal monitors downlink control information according to the beam configuration information.

[0176] Taking two search spaces, namely search space 0 and search space 1, as an example, the time-frequency resources occupied by these two search spaces include but are not limited to Figure 8 Of course, the present application is not limited to the several modes shown in (a) to (d). The downlink control information sent by the base station to the terminal is resource-mapped according to the search spac...

Embodiment 3

[0183] The beam configuration information includes: beam indication information, monitoring period indication information and multi-beam configuration indication information (multi-beam config). The multi-beam configuration indication information may be understood as: it is used to indicate the monitoring rules of the terminal when the monitoring periods of multiple beams overlap. For example, assuming that the monitoring period of beam 1 is 1 time slot, and the monitoring period of beam 2 is 2 time slots, the terminal will monitor the two beams in one time slot every 2 time slots. However, how to monitor specifically is the technical problem to be solved in this embodiment.

[0184] It should be noted that, in this embodiment, the monitoring rules of the terminal are mainly aimed at when the monitoring periods of multiple beams overlap. When the duty cycles of multiple beams do not overlap, the beam may be monitored on each symbol of the monitoring period where the monitorin...

Abstract

Embodiments of the invention disclose a communication method and apparatus, and relates to the technical field of communication. The communication method includes the steps: generating beam configuration information which includes beam indication information and beam monitoring information, and then sending the beam configuration information to a terminal. The technical scheme of the communicationmethod can be applied to a scene in which the terminal to monitor and receive beams according to the beam configuration information so as to receive downlink information sent from a base station, ora scene in which the terminal sends uplink information through a sending beam according to the beam configuration information.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a communication method and device. Background technique [0002] Regarding the transmission of the control channel in the 5G standard currently being discussed, due to the introduction of the concept of multi-beam, in order to improve the robustness of the control channel, the terminal can be configured to monitor multiple beams. [0003] According to the discussion of 5G, multiple beams can be maintained between the base station and the terminal. The multiple beams used for control channel transmission and monitoring may be a subset of the maintained multiple beams, which requires the base station to configure which specific beams the terminal detects. [0004] The current prior art does not provide a technical solution for the base station to configure which beams the terminal specifically monitors. Contents of the invention [0005...
