Description

Method, device, equipment and readable storage medium for transmitting configuration information

Technical Field

The present disclosure relates to the field of wireless communications, and in particular, to a method, an apparatus, a device, and a readable storage medium for transmitting configuration information.

Background

In the course of the development of wireless communication technology, how to reduce the energy consumption of a base station is a hot spot of research.

One way to reduce the power consumption of a base station is to dynamically switch space elements, such as certain antenna elements, ports, transceiver chains (TRX chain), beams, panels, etc., but dynamic switch space elements may cause the actually transmitted beams or pilots to change, such as certain beams being turned off or certain pilots being turned off, etc.

In view of the downlink channel measurements and downlink beam management, the base station may configure multiple pilots for channel measurements, link listening, beam recovery. If the switch space unit is dynamic, it may result in configured pilots (e.g., pilots for channel measurement, link listening, beam recovery as described above) that have no way to be normally monitored and measured by the user equipment, resulting in inaccurate channel measurements, link measurements, etc.

Wherein QCL types (including QCL type a, QCL type B, QCL type C, and QCL type D) can be used to determine the relationship of the reception beams of different signals or different channels.

Having the same QCL reference source means that two different resources have the same QCL reference source when they have a QCL relationship with the same tracking reference signal (tracking reference signal, TRS). Thus, when multiple pilots have a QCL relationship with the same tracking reference signal (tracking reference signal, TRS), the multiple pilots are said to have the same QCL reference source.

Pilots belonging to the same spatial cell group have the same QCL type D reference source.

Alternatively, pilots belonging to the same spatial cell group correspond to multiple subgroups, each subgroup having the same QCL type D reference source.

In some possible implementations, the network device sends MAC signaling to the user equipment, the MAC signaling including the shutdown indication information.

In some possible embodiments, the closing instruction information indicates an identifier of a space unit group, so that after receiving the closing instruction information, the ue can learn that each space unit group corresponding to the indicated identifier is a space unit group that needs to be closed.

And S203, after the first moment, the user equipment closes the space unit group indicated by the closing instruction information, wherein the first moment is a moment corresponding to a set duration after the second moment, and the second moment is a moment when the closing instruction information is received.

In an example, the network device sends the MAC CE to the user device, where the MAC CE includes the close indication information, and the second time is an end position of a time slot where the MAC CE is located.

In an example, the network device configures 32 spatial cell groups for the UE through RRC layer signaling and uses MAC signaling for activation, 8 of the configured 32 spatial cell groups may be activated at a time. The DCI is used after activation to indicate the set of space units to be closed out of the 8 sets of space units that have been activated, for example: the 3 bits are used to indicate 1 out of the 8 spatial cell groups that have been activated. By activating a partial set of spatial units using MAC signaling and dynamically indicating to close a partial set of spatial units in the activated set of spatial units using DCI, bit overhead of the close indication may be saved compared to a way of indicating to close 32 configured sets of spatial units.

the maximum number of space unit groups configurable by a single user equipment according to the protocol is determined, for example: the number of bits is equal to the maximum number of the configurable space unit groups of the single user equipment agreed by the protocol (the maximum number of the configurable space unit groups of the single user equipment agreed by the protocol is 16, and the number of bits is 16);

and determining according to the number of the space unit groups activated by the user equipment, wherein the number of bits is equal to the number of the space unit groups activated by the user equipment.
