Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms "comprises," "comprising," or any other variation thereof, in the description and claims of this application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Furthermore, the use of "and/or" in the specification and claims means that at least one of the connected objects, such as a and/or B, means that three cases, a alone, B alone, and both a and B, exist.

In order to facilitate understanding of the embodiments of the present invention, several technical points are described below:

firstly, regarding descending Cross-slot scheduling (Cross-slot scheduling) and descending simultaneous slot scheduling (Same-slot scheduling):

a fifth generation mobile communication (5th-generation, 5G) terminal supports downlink Cross-slot scheduling and downlink Same-slot scheduling:

(1) descending Same-slot scheduling: a Physical Downlink Control Channel (PDCCH) of a current slot (slot) (a filled part of fig. 1 represents two Orthogonal Frequency Division Multiplexing (OFDM) symbols for transmitting the PDCCH) schedules a Physical Downlink Shared Channel (a blank part of fig. 1 represents 12 OFDM symbols in one slot for transmitting the Physical Downlink Shared Channel (PDSCH)) of the same slot.

After the terminal receives the PDCCH of multiple (e.g., two) symbols (padding part of fig. 1), extra processing time is required for decoding (decoding) to obtain the content of the PDCCH transmission (e.g.: downlink Control Information (DCI), including Resource Block (RB) allocation information, etc., therefore, before obtaining the RB allocation information, the terminal needs to receive and buffer the PDSCH of the entire bandwidth or bandwidth Part (BWP), compare power consumption, the number of time slots between the time slot of the PDCCH and the time slot of the PDSCH scheduled by the PDCCH, as indicated by the parameter K0, since the Same-slot scheduling is a PDCCH scheduling PDSCH of the Same slot, therefore, the K0 is 0slot, the related protocol supports that the base station indicates Time Domain Resource Allocation (TDRA) for each downlink scheduling through DCI, and the TDRA includes a K0 value, for the Same-slot scheduling, K0 is 0;

(2) downlink cross-slot scheduling: and the PDCCH of the current slot schedules the PDSCH of the subsequent different slots.

After the terminal receives the PDCCH with multiple (e.g., two) symbols, there is enough time to decode to obtain the content (e.g., DCI) of the PDCCH transmission, including RB allocation information, and so on, so the terminal only needs to receive the corresponding PDSCH on the relevant RB (there is no need to additionally receive and buffer the PDSCH with bandwidth, and thus power is saved); cross-slot scheduling is that the PDCCH schedules PDSCH of different slots, so K0 must be greater than 0.

In the discussion of the relevant standards, the handover between Cross-slot scheduling and same-slot scheduling may be triggered by layer 1(L1) signaling, and the L1 signaling may be DCI carried by PDCCH, which may be scheduling DCI or non-scheduling DCI.

To ensure the power saving of downlink Cross-slot scheduling, two conditions need to be satisfied:

condition 1: the base station triggers downlink Cross-slot scheduling of the terminal through the PDCCH;

condition 2: minimum K0> a; a > -0, a may be network configured or predefined.

For example, the minimum K0 may be configured, predefined, or take a default value by the network through Radio Resource Control (RRC) signaling or other signaling; when the two conditions are met, the terminal assumes that the value of K0 indicated by the subsequent base station through the scheduling DCI (or the TDRA field of the scheduling DCI) is greater than or equal to the minimum value of K0 until the base station triggers the terminal to close Cross-slot scheduling, and at this time, the terminal assumes that the value of K0 indicated by the subsequent base station through the scheduling DCI (or the TDRA field of the scheduling DCI) is greater than or equal to the minimum value of K0 and may be smaller than the minimum value of K0. It is clear that the minimum K0 and K0 are two different parameters. In a related protocol, K0 may be indicated by a TDRA field in DCI transmitted by a downlink scheduling PDCCH, and the minimum K0 is the minimum value of K0.

Two, regarding the Cross-slot scheduling and the Same-slot scheduling of the uplink:

the background and problems of uplink Cross-slot scheduling are similar to those of downlink Cross-slot scheduling, and the main difference is that the downlink parameter is K0, and the uplink parameter is K2, where the number of slots between the slot where the PDCCH is located and the slot where the PUSCH is scheduled is located is represented by a parameter K2.

To ensure the power saving of uplink Cross-slot scheduling, two conditions need to be satisfied:

condition 1: the base station triggers uplink Cross-slot scheduling of the UE through the PDCCH;

condition 2: minimum K2 > B; b > -0, B may be network configured or predefined

Wherein, the minimum K2 is configured by the network through RRC signaling or other signaling or adopts a default value; when the two conditions are met, the terminal considers that the value of K2 indicated by the subsequent base station through the scheduling DCI (or the TDRA field of the scheduling DCI) is greater than or equal to the minimum value K2 until the base station triggers the terminal to close uplink Cross-slot scheduling. It is clear that the minimum K2 and K2 are two different parameters. In a related protocol, K2 may be indicated by a TDRA field in DCI transmitted by an uplink scheduling PDCCH, and the minimum K2 is the minimum value of K2.

2) the UE reports the related state of closing downlink Cross-slot scheduling by the network, or the UE requests the network whether the current state is the related state of Cross-slot scheduling or not, or the UE requests the network for minimum K0 configuration;

3) after receiving the UE request, the base station retransmits the status indication information, for example: whether it is a cross-slot scheduling related status; or, the base station retransmits the minimum K0 configuration after receiving the UE request;

4) the UE performs adjustments based on the retransmitted information, for example: and closing the Cross-slot scheduling related state of the downlink.

2) the UE reports the related state that the network closes the uplink Cross-slot scheduling, or the UE requests the network whether the current state is the related state of the Cross-slot scheduling, or the UE requests the network for minimum K2 configuration;

3) after receiving the UE request, the base station retransmits the status indication information, for example: whether it is a cross-slot scheduling related status; or, the base station retransmits the minimum K2 configuration after receiving the UE request;

4) the UE performs adjustments based on the retransmitted information, for example: and closing the related state of uplink Cross-slot scheduling.

Treatment method 2:

if the UE receives a signaling that the base station triggers uplink Cross-slot scheduling, but the UE receives a signal that K2 indicated by the base station through the TDRA field is smaller than the minimum K2 value, one or more of the following may be performed:

1) the UE continues to work in cross-slot scheduling; alternatively, the UE assumes that the minimum K2 value is unchanged;

Treatment method 3:

1) the UE continues to operate in cross-slot scheduling, or the UE assumes that the minimum K2 is unchanged.

2) If the UE receives the next status indication message (for example: whether the UE is in the cross-slot scheduling related state) if N K2 (i.e. K2 indicated by DCI) are received within a period of time before the UE is in the cross-slot scheduling related state) and the minimum K2 value is smaller, the UE turns off the cross-slot scheduling related state, or the UE assumes that the minimum K2 is changed; wherein N is network configured or protocol defined;
