Embodiment Construction

[0092] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0093] The terms involved in this application will be introduced below.

[0094] 1. Beam:

[0095] A beam is a communication resource, and different beams can be considered as different communication resources. Different beams can transmit the same information or different information. The beams may correspond to at least one of time domain resources, space resources and frequency domain resources.

[0096] Optionally, multiple beams with the same or type of communication characteristics may be regarded as one beam, and one beam may include one or more antenna ports for transmitting data channels, control channels, sounding signals, and the like. For example, a transmit beam may refer to the distribution of signal strengths in different directions in space after a signal is transmitted from an antenna; a receive beam may refer to the signal streng...

Abstract

The present application provides a method and apparatus for determining the state of an antenna panel. The terminal receives configuration information including at least one set of downlink signal resources, and when it is determined that the first antenna panel corresponding to the first set of downlink signal resources is turned on, uses the first antenna panel to measure the first set of downlink signal resources quality of the resources in the first downlink signal resource set, and send first feedback information, where the first feedback information may indicate the quality of the resources in the first downlink signal resource set. When the first antenna panel is turned off, the quality of resources in the first downlink signal resource set is not measured, and second feedback information is sent, where the second feedback information is used to indicate that the first antenna panel is turned off. In this way, the network device in the embodiment of the present application can know the state of the antenna panel, and then can reasonably schedule the antenna panel, thereby improving the data transmission efficiency.

Description

technical field [0001] The present application relates to the field of communications, and more particularly, to a method and apparatus for determining the state of an antenna panel. Background technique [0002] The fifth generation mobile communication system (5th generation, 5G) can use high-frequency communication, that is, use an ultra-high frequency band (eg, >6 GHz) to transmit data. A major problem with high-frequency communication is that the signal energy drops sharply with the transmission distance, resulting in short signal transmission distances. In order to overcome this problem, high-frequency communication adopts analog beam technology. By weighting a large-scale antenna array, the signal energy is concentrated in a smaller range to form a beam-like signal (which can be called "analog beam"). ”, which can also be referred to as “beam” for short), thereby increasing the transmission distance. [0003] Network equipment can generate different beams, pointi...
