Embodiment 1

[0086] Such as figure 1 As shown, the embodiment of the present disclosure provides a method for determining a beam monitoring object, including:

[0087] Step 101: Determine TCI (Transmission Configuration Indication) information of the control channel;

[0088] Generally speaking, TCI information is configured through high-level signaling or Media Access Control (MAC, Media Access Control) signaling. TCI is mainly used to indicate transmission-related parameters, such as quasi-co-location QCL parameters.

[0089] Step 102: Determine a reference signal set q1 according to the transmission configuration indication information, where q1 includes reference signals for indicating spatial parameters;

[0090] It should be noted that QCL parameters include QCL indications about spatial parameters. The spatial parameters generally represent the transmission beam implicitly, which indicates a reference signal or a group of reference signals that are relatively close to the spatial parameters ...

Embodiment 2

[0098] Such as figure 2 As shown, the embodiment of the present disclosure provides a method for determining a beam monitoring object, including:

[0099] Step 201: Obtain a preset beam monitoring reference signal set q4;

[0100] Step 202: Determine the transmission configuration indication information of the control channel to be detected;

[0101] Step 203: Determine a reference signal set q1 according to the transmission configuration indication information, where q1 includes reference signals for indicating spatial parameters;

[0102] Step 204: Set the intersection of q4 and q1 or a subset of the intersection as the beam monitoring reference signal set q2.

[0103] It is understandable that since aperiodic reference signals may be excluded, the beam monitoring reference signal set q2 may also be set to a subset of the intersection of q4 and q1.

[0104] Optionally, if there is no intersection between q4 and q1, then q2 is q1, or a subset of q1, or an empty set.

[0105] It is under...

Embodiment 3

[0109] Such as image 3 As shown, the embodiment of the present disclosure provides a configuration method, including:

[0110] Step 301: Determine the corresponding indication reference signal in the TCI state candidate set of the control channel;

[0111] Wherein, the indication reference signal corresponds to the spatial parameter of the state in the TCI state candidate set.

[0112] Step 302: Determine the type of the indicated reference signal;

[0113] Step 303: Determine whether the type of the indicated reference signal includes an aperiodic reference signal;

[0114] Step 304: If the judgment result is yes, the base station configures the beam monitoring reference signal set q2 used when the TCI points to the aperiodic reference signal.

Description

Technical field [0001] The present disclosure relates to the field of virtual reality technology, and in particular to a method and device for determining a beam monitoring object. Background technique [0002] In the fifth-generation mobile communication technology (5G, 5rd-generation), the 5G base station side uses a large-scale antenna array, and uses beamforming technology to form a directional beam (Beam) for communication. To ensure that sufficient signal gain is ultimately obtained, the base station needs to use a large number of narrow beams to ensure that users in any direction in the cell can be effectively covered, that is, the narrower the beam, the greater the signal gain. However, the use of narrow beam transmission is more sensitive to the movement of the user equipment and the blocking of the beam link, especially in high frequencies, where the blocking phenomenon is more serious, which often causes the failure of the beam link. Therefore, when the wireless chann...
