Description

Method for determining validity of reference signal transmission opportunity and user equipment

[ field of technology ]

The present invention relates to the field of communications technologies, and in particular, to a method for determining validity of reference signal transmission opportunity and a user equipment.

[ background Art ]

Currently, 3GPP R17 is standardizing a mechanism for small data transmission (Small Data Transmission, SDT for short) based on periodic uplink scheduling-free resources. In idle/inactive (inactive) state, there is a problem that the transmission timing of SDT overlaps (overlap) with the Paging timing (PO)/Paging advance indication (Paging Early Indication, PEI). The transmission timing of the SDT may be an uplink data transmission timing or a downlink receiving window.

When the transmission opportunity of the SDT collides with the PO/PEI transmission opportunity, the User Equipment (UE for short) usually prioritizes SDT, i.e.: the transmission of uplink data or the reception of feedback information is preferentially performed, without receiving PEI and paging (paging) messages.

In idle/inactive (idle) state, the validity of the reference signal needs to be indicated by the network side, that is, the UE needs to determine whether the subsequent reference signal transmission opportunity is valid by receiving the reference signal validity indication issued by the network side device in advance, that is: determining whether a reference signal exists at a subsequent reference signal transmission occasion. The Reference Signal may be a tracking Reference Signal (Tracking Reference Signal, abbreviated as TRS) or a channel state information-Reference Signal (Channel State Information-Reference Signal, abbreviated as CSI-RS).

However, in the related art, there is no scheme capable of determining the validity of the reference signal transmission timing when the transmission timing of the SDT collides with the PO/PEI transmission timing.

If the PO of the current paging cycle does not collide with the uplink data transmission opportunity, the PO of the current paging cycle is available.

If the PO of the current paging cycle collides with the downlink receiving window, the UE can receive the feedback information sent by the network side equipment through the downlink receiving window, and the PO of the current paging cycle is unavailable. If the PO of the current paging cycle does not collide with the downlink receiving window, the PO of the current paging cycle is available.

If the PEI transmission opportunity of the current paging cycle collides with the uplink data transmission opportunity, the UE can send uplink data to the network side equipment through the uplink data transmission opportunity, and the PEI transmission opportunity of the current paging cycle is unavailable. If the PEI transmission opportunity of the current paging cycle is not collided with the uplink data transmission opportunity, the PEI transmission opportunity of the current paging cycle is available.

If the PEI transmission opportunity of the current paging cycle collides with the downlink receiving window, the UE can receive feedback information sent by the network side equipment through the downlink receiving window, and the PEI transmission opportunity of the current paging cycle is unavailable.
