Embodiment Construction

[0069] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0070] The first embodiment of the present invention provides a codebook determination method, such as figure 1 and 7 As shown in the figure, the following specific steps are included:

[0071] Step S11, the UE determines the timing at which the UE can receive physical downlink shared channel PDSCH data according to the timing of being woken up;

[0072] During the implementation of this step, it specifically includes: the UE det...

Abstract

The invention discloses a codebook determination method, a codebook determination device, a terminal, a base station and a storage medium, and the codebook determination method comprises the steps that UE determines the time when the UE can receive PDSCH data according to the awakened time; and the UE forms a corresponding hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook according to the time when the PDSCH data can be received. In the embodiment of the invention, the UE determines the opportunity of receiving the PDSCH data from the middle machine capable of transmitting the PDSCH data, and then forms the codebook for the opportunity of receiving the PDSCH data, so that the problem of higher codebook overhead is solved, the size of the codebook is reduced, and the codebook overhead is reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a codebook determination method, a codebook determination device, a terminal, a base station and a storage medium. Background technique [0002] In the existing codebook determination method, the UE always calculates the possible timing of PDSCH transmission according to the value set of the interval K1, regardless of whether the base station sends PDSCH data at this timing, and regardless of whether the UE receives PDSCH at this timing, The UE always forms a HARQ-ACK codebook for each occasion. In order to make the UE energy-saving, a new channel or signal is introduced, called WUS or WUP, whose basic function is to wake up the sleeping UE. Generally, after the UE is woken up by WUS / WUP, the UE will need to work in the corresponding carrier or bandwidth. That is to say, before WUS / WUP, the UE handles the sleep state to save energy. After waking up, the UE...
