Referring to fig. 1, an embodiment of the present invention provides a method for configuring a relay threshold of a terminal, where an execution subject of the method is a network device, for example, a base station, and includes step 101.

Step 101: and sending configuration information to the UE, wherein the configuration information is used for configuring a threshold parameter for the UE to provide the relay service.

The above configuration information is equivalent to configuring the UE to use a relay function, which means that the UE provides a relay service (or UE to UE relay service) to one or more other UEs (e.g. remote UE).

Further, a UE capable of providing relay service may also be referred to as a relay UE, which may provide relay service between a network device to one or more remote UEs, or which may provide relay service between one or more UEs (e.g., other relay UEs) to one or more remote UEs.

In some embodiments, the step 101 may include: receiving indication information from the UE, the indication information indicating that the UE is capable of providing the relay service; and then sending configuration information to the UE according to the indication information.

In some embodiments, the threshold parameter mentioned in step 101 may include one or more of the following:

(1) a signal quality threshold;

further, the signal quality threshold may include one or more of: highest signal quality in a non-Supplemental Uplink (SUL) cell; lowest signal quality in non-SUL cells; highest signal quality in the SUL cell; a lowest signal quality in a SUL cell, wherein the signal quality of the UE being less than or equal to the highest signal quality indicates that the UE is capable of providing a relay service, or the signal quality of the UE being greater than or equal to the lowest signal quality indicates that the UE is capable of providing a relay service.

(2) A first distance threshold value representing a distance threshold between the UE and the network device;

further, the first distance threshold value includes one or more of: a minimum distance between the UE and the network device in a non-SUL cell; a maximum distance between the UE and the network device in a non-SUL cell; the minimum distance between the UE and the network equipment in the SUL cell; a maximum distance between the UE and the network device in the SUL cell, where a distance between the UE and the network device is smaller than or equal to the maximum distance, indicating that the UE is capable of providing the relay service, or a distance between the UE and the network device is greater than or equal to the minimum distance, indicating that the UE is capable of providing the relay service.

(3) A second distance threshold value, the second distance threshold value representing a distance threshold between the UE and a remote terminal remote UE;

further, the second distance threshold value includes one or more of: a maximum distance between the UE and the remote UE in a non-SUL cell; the maximum distance between the UE and the remote UE in the SUL cell. Wherein, if the distance between the UE and the remote UE is less than or equal to the maximum distance, it indicates that the UE can provide the relay service.

In the embodiment of the invention, the network side can issue the threshold parameter for configuring the UE to provide the relay service to the UE, so that the UE can determine whether to provide the relay service according to the threshold parameter, the UE is prevented from blindly determining to provide the relay service, and the power consumption of the relay UE is further reduced.

Referring to fig. 2, an embodiment of the present invention further provides a method for controlling a relay service, where an execution subject of the method is a UE, and the method includes: step 201 and step 202.

Step 201: receiving configuration information from a network device, wherein the configuration information is used for configuring a threshold parameter for providing a relay service;

in some embodiments, before step 201, the UE sends indication information to the network side, where the indication information indicates that the UE is capable of providing the relay service.

Step 202: and judging whether to provide the relay service according to the configuration information.

In some embodiments, in step 202, it may be determined whether to provide the relay service according to the configuration information and the cell in which the UE is located.

In some embodiments, the threshold parameter mentioned in step 201 may include one or more of the following:

(1) a signal quality threshold;

Referring to fig. 3 and 4, a network deployment coverage may include non-SUL cells (e.g., Cell 1(Cell1)) and SUL cells (e.g., Cell 2(Cell 2)).

When the UE connects to Cell1 and Cell2, the UE may provide UE-to-UE relay service to other UEs. For example, the UE may be referred to as a Relay UE in Cell1 (Relay UE in Cell1) and/or a Relay UE in Cell2 (Relay UE in Cell 2).

However, if the UE is too close to the base station (i.e., the distance between the UE and the base station is short), or the UE is at a cell border UE, the UE may not be suitable as a relay UE to provide UE to UE relay service.

Because when the relay UE (relay UE) is too close to the base station, the distance from the relay UE to the remote UE may be relatively long, which may result in especially large power consumption of the relay UE. When the UE is located at the cell boundary, the distance between the relay UE and the base station is also relatively long, and there is a problem that the power consumption of the relay UE is particularly large. It is necessary to specify the range of the UE as a relay UE. The method comprises the following specific steps:

step 1: when the network knows that the UE can provide the UE to UE relay service, for example, the UE reports that the UE has the UE to UE relay capability, the base station issues the relay threshold capable of providing the UE to UE relay service to the UE.

Different relay thresholds may be set for different cells, including for example: SUL cell threshold and non-SUL cell threshold. Further, the relay threshold may include: a signal quality parameter within the non-SUL cell and the SUL cell, and/or a distance (distance) parameter within the non-SUL cell and the SUL cell.

Illustratively, the relay threshold may include one or more of:

(1) the maximum signal quality T1 of the non-SUL cell, when the signal quality signal of the UE is T1, the UE can provide the UE to UE relay service in the non-SUL cell (or the UE can provide the UE to UE relay function in the non-SUL cell).

(2) The non-SUL cell has the lowest signal quality T2, and when the signal quality signal > of the UE is T2, the UE can provide the UE to UE relay service in the non-SUL cell.

(3) The SUL cell has the highest signal quality T3, and when the signal quality signal of the UE is < ═ T3, the UE can provide UE to UE relay service in the SUL cell.

(4) The non-SUL cell has the lowest signal quality T4, and when the signal quality signal > of the UE is T4, the UE can provide the UE to UE relay service in the SUL cell.

It should be noted that, the threshold values used for determining whether the terminal can provide the UE to UE relay service in the SUL cell and the non-SUL cell may be equal.

Illustratively, the relay threshold may include one or more of:

(1) the minimum distance D1 in the non-SUL cell, when the UE is located at the distance > D1 from the base station, the UE can provide UE to UE relay service in the non-SUL cell.

(2) The maximum distance D2 in the non-SUL cell, when the UE is in the distance from the base station ═ D2, the UE can provide UE to UE relay service in the non-SUL cell.

(3) The minimum distance D3 in the SUL cell, when the UE is located at the distance > D3 from the base station, the UE can provide UE relay service in the SUL cell.

(4) The SUL cell has the maximum distance D4, and when the distance between the UE and the base station is equal to D4, the UE can provide UE relay service in the SUL cell.

(5) And d, when the distance between the UE and the remote UE is less than d, the UE can provide the UE to UE relay service in the SUL cell or the non-SUL cell.

Step 2: when the UE receives a relay threshold for providing the UE to UE relay service, which is issued by the network, the UE may determine whether to provide the UE to UE relay service according to a cell where the UE is located, an SUL cell or a non-SUL cell.

It can be understood that, when the UE does not satisfy the above relay threshold, the UE can only directly use Uu to connect with the network side or the UE as a remote UE.
