Description

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

[ technical field ] A method for producing a semiconductor device

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

[ background of the invention ]

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

When the transmission timing of the SDT collides with the PO/PEI transmission timing, a User Equipment (UE) generally performs the SDT preferentially, that is: the sending of the uplink data or the receiving of the feedback information is preferentially performed without receiving the PEI and the paging message.

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

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

The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be understood that the term "and/or" as used herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., A and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

In the embodiment of the present invention, the transmission opportunity of the SDT may include an uplink data transmission opportunity or a downlink receiving window, where the uplink data transmission opportunity may be used to send uplink data by using an uplink scheduling-free resource, and the downlink receiving window may be used to receive feedback information corresponding to the uplink data sent by the network side device. As an alternative, the network side device may be a base station.

If the PO of the current Paging Cycle (Paging Cycle) collides with the uplink data transmission time, the UE may send the uplink data to the network side device through the uplink data transmission time, but the PO of the current Paging Cycle is unavailable. If the PO of the current paging cycle does not collide with the uplink data transmission time, 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 time of the current paging cycle collides with the uplink data transmission time, the UE can send the uplink data to the network side equipment through the uplink data transmission time, and the PEI transmission time of the current paging cycle is unavailable. And if the PEI transmission time of the current paging cycle does not collide with the uplink data transmission time, the PEI transmission time of the current paging cycle is available.

If the PEI transmission time 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 PEI transmission time of the current paging cycle is unavailable. And if the PEI transmission time of the current paging cycle does not collide with the downlink receiving window, the PEI transmission time of the current paging cycle is available.

In the embodiment of the present invention, the collision between the PO and SDT transmission occasions of the current paging cycle may specifically include: the PO of the current paging cycle collides with the uplink data transmission time, or the PO of the current paging cycle collides with the downlink receiving window.

In the embodiment of the present invention, the non-collision of the PO and SDT transmission occasions in the current paging cycle may specifically include: the PO of the current paging cycle does not collide with the uplink data transmission opportunity and the PO of the current paging cycle does not collide with the downlink receiving window.

In the embodiment of the invention, the validity of the reference signal transmission opportunity indicates that the reference signal transmission opportunity is available, and the invalidity of the reference signal transmission opportunity indicates that the reference signal transmission opportunity is unavailable.

In the embodiment of the present invention, the reference signal may be a TRS or a CSI-RS, and the reference signal transmission timing may be a TRS transmission timing or a CSI-RS transmission timing.

As shown in fig. 1a, for example, a PEI transmission timing, a Synchronization Signal Block (SSB) transmission timing, a reference Signal transmission timing, and a PO are sequentially arranged in one paging cycle, where the number of SSB transmission timings may be multiple, and only one SSB is described in fig. 1a as an example. In this embodiment, as shown in fig. 1a, as an alternative, the reference signal transmission timing corresponding to the PO is located before and closest to the PO. Alternatively, the reference signal transmission timing corresponding to the PO is located before the PO and closest to the SSB transmission timing, which is not shown in fig. 1 a.

In the embodiment of the present invention, in an idle state or an inactive state, the UE may complete time-frequency synchronization, Automatic Gain Control (AGC) and Radio Resource Management (RRM) measurement for a serving cell through one or more SSBs. In the process of performing the time-frequency synchronization, AGC, and RRM measurements, the UE may be frequently awakened, thereby increasing power consumption of the UE. To solve the above problem, the time-frequency synchronization, AGC, and RRM measurements may be centralized by the TRS or CSI-RS to reduce the number of times of wake-up of the UE, thereby reducing the power consumption of the UE.

The UE receives the PEI sent by the network side equipment through the PEI transmission opportunity of the current paging cycle.

As an alternative, the eighth bit field may be 1bit, for example, when the eighth bit field is "1", it indicates that the reference signal transmission timing corresponding to the PO of the current paging cycle is valid, and when the eighth bit field is "0", it indicates that the reference signal transmission timing corresponding to the PO of the current paging cycle is invalid.

In this embodiment, if the PEI transmission timing of the current paging cycle collides with the transmission timing of the SDT, it is determined whether the reference signal transmission timing corresponding to the PO of the current paging cycle is valid or invalid, thereby achieving the validity of determining the reference signal transmission timing when the PEI transmission timing of the current paging cycle collides with the transmission timing of the SDT.

In this embodiment, if the PEI transmission timing of the current paging cycle collides with the transmission timing of the SDT, the UE determines whether the reference signal transmission timing corresponding to the PEI transmission timing of the next paging cycle is valid or invalid, thereby achieving the validity of determining the reference signal transmission timing when the PEI transmission timing of the current paging cycle collides with the transmission timing of the SDT.
