Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The method for communicating based on the auxiliary resource set provided by the embodiment of the present disclosure may be applied to the direct connection communication system shown in fig. 1. Referring to fig. 1, in a scenario of performing direct connection communication between direct connection communication devices, a network device configures various transmission parameters for data transmission for the direct connection communication device 1. The direct connection communication device 1, the direct connection communication device 2 and the direct connection communication device 3 perform direct connection communication. There may be an obstacle between the direct communication device 2 and the direct communication device 3. The link for communication between the network device and the direct connection communication device is an uplink and downlink link, and the link between the direct connection communication device and the direct connection communication device is a direct connection link (Sidelink).

In the present disclosure, a communication scenario for direct communication between direct connection communication devices may be a Vehicle to event (V2X) service scenario. Wherein V represents an in-vehicle device and X represents any object interacting with the in-vehicle device. Currently X mainly contains on-board equipment, handheld devices, traffic side infrastructure and networks. The information mode of V2X interaction includes: interaction between the Vehicle-mounted device and the Vehicle-mounted device (V2V), between the Vehicle-mounted device and the roadside device (V2I), between the Vehicle-mounted device and the handheld device (V2P), and between the Vehicle-mounted device and the Network (V2N).

With the development of a new generation of 5G mobile communication technology, support for new V2x communication services and scenarios, such as fleet management (Vehicles platform), Extended sensing (Extended Sensors), Advanced Driving (Advanced Driving), and remote Driving (remote Driving), is implemented in 3GPP Rel-16 by using 5G NR technology. In general, 5G V2x sidelink can provide higher communication speed, shorter communication delay and more reliable communication quality.

The communication scenario for direct communication between direct communication devices may also be a terminal-to-terminal (D2D) communication scenario. The direct communication device performing direct communication in the embodiments of the present disclosure may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, which have wireless communication functions, and various forms of User Equipment (UE), Mobile Stations (MS), terminals (Terminal), Terminal devices (Terminal Equipment), and the like. For convenience of description, the following embodiments of the present disclosure take a direct connection communication device as a user equipment as an example for explanation.

Among other things, the enhancement of NR Sidelink can improve transmission reliability and reduce latency. In the NR Sidelink enhancement, in terms of enhancing Mode2 resource allocation, 3GPP working group reaches the conclusion, and needs to research a way for assisting resource selection among ues. In this approach, two user equipments are specified, such as user equipment a and user equipment B. Wherein user equipment a is a secondary user equipment of user equipment B. The user equipment B is the user equipment that needs to perform resource selection for own data transmission. The user equipment a provides the auxiliary information and sends the auxiliary information to the user equipment B in a mode2, and when the user equipment B selects the resource, the auxiliary information sent by the user equipment a is considered, that is, the user equipment B uses an auxiliary information assistance mechanism to select the resource. Wherein user device B may send data to user device a and/or other user devices.

In the related art, the auxiliary information sent by the ue a for the ue B may be an auxiliary resource set, and the auxiliary resource set supports different auxiliary resource set types. The auxiliary resource Set type of the auxiliary resource Set sent by the ue a to the ue B includes a Set of resources preferred for the ue B's transmission and a Set of resources non-preferred for the ue B's transmission.

In the related art, the user equipment B needs to distinguish the types of the received auxiliary resource sets and perform different processing for different types of auxiliary resource sets. For example, for the type of the auxiliary resource set preferred by the user equipment B, the user equipment B intersects the perceived resource set with the type of the auxiliary resource set preferred by the user equipment B to determine a resource set required for data transmission. For the non-preferred auxiliary resource set type of the user equipment B, the user equipment B makes a difference between the perceived resource set and the non-preferred auxiliary resource set type of the user equipment B, that is, the user equipment B excludes the non-preferred auxiliary resource set type of the user equipment B from the perceived resource set, so as to determine the resource set required for data transmission. However, in the related art, the ue a cannot determine the type of the auxiliary resource set required by the ue B, and thus cannot determine which type of the auxiliary resource set is provided for the ue B.

In view of this, an embodiment of the present disclosure provides a method for performing communication based on an auxiliary resource set, where a user equipment providing the auxiliary resource set determines a type of the auxiliary resource set, and sends the auxiliary resource set corresponding to the determined type of the auxiliary resource set, so that a first user equipment can determine and send the auxiliary resource set corresponding to the type of the auxiliary resource set required by a second user equipment, and communication based on the auxiliary resource set is enhanced.

Namely, the first user equipment provides an auxiliary resource set for the second user equipment, and the second user equipment performs resource selection and data transmission by using the auxiliary resource set provided by the first user equipment. In other words, the first user equipment and the second user equipment communicate with each other based on the auxiliary information, which may also be understood as the first user equipment and the second user equipment communicate with each other based on the auxiliary resource set.

In step S11, an auxiliary resource set type provided to the second user equipment is determined based on the configuration information of the resource pool.

In step S12, an auxiliary resource set corresponding to the auxiliary resource set type is sent to the second user equipment.

In this embodiment of the present disclosure, the configuration information of the resource pool may include an auxiliary resource set type, where the auxiliary resource set type may be a preferred auxiliary resource set (preferred resource set) or may also be a non-preferred resource set (non-preferred resource set).

The first device may determine the type of the auxiliary resource set based on the configuration information of the resource pool, and send the auxiliary resource set corresponding to the type of the auxiliary resource set, so as to send the auxiliary resource set corresponding to the type of the required auxiliary resource set. For example, an auxiliary resource set corresponding to the type of the auxiliary resource set required by the second user equipment may be sent.

The resource pool includes a transmission resource pool (TX pool) and a reception resource pool (RX pool). Wherein, the sending resource pool and the receiving resource pool can be in one resource pool. The sending resource pool and the receiving resource pool may not be in one resource pool.

Hereinafter, for convenience of description, the transmission resource pool of the first user equipment is referred to as a first transmission resource pool. And the transmission resource pool of the second user equipment is called a second transmission resource pool. The secondary resource set type determined based on the configuration information of the first transmission resource pool is referred to as a first secondary resource set type. The secondary resource set type determined based on the configuration information of the second transmission resource pool is referred to as a second secondary resource set type. And the first sending resource pool and the second sending resource pool are pre-configured with auxiliary resource set types. The first secondary resource set type may be a secondary resource set type of the first transmission resource pool. The second auxiliary resource set type may be an auxiliary resource set type of the second transmit resource pool.

FIG. 3 is a flow diagram illustrating a method for determining a secondary resource set type, which may be performed alone or in combination with other embodiments of the present disclosure, according to an example embodiment. As shown in fig. 3, the method of determining a type of a secondary resource set is performed by a first user equipment and comprises the following steps.

In the embodiment of the present disclosure, the first resource pool is preconfigured with the auxiliary resource set type. The first user equipment determines an auxiliary resource set type of the first transmission resource pool. The first user equipment may provide the corresponding auxiliary resource set in accordance with the pre-configured auxiliary resource set type of the first resource pool. In other words, the first auxiliary resource set type may be a pre-configured auxiliary resource set type of the first resource pool.

In one embodiment, the first transmission resource pool and the second transmission resource pool belong to the same transmission resource pool. The first user equipment and the second user equipment can achieve the understanding that the auxiliary resource set types are consistent, that is, the auxiliary resource set types corresponding to the first sending resource pool and the second sending resource pool are consistent. And the first user equipment provides a corresponding auxiliary resource set to the second user equipment according to the pre-configured auxiliary resource set type of the first resource pool. After receiving the auxiliary resource set sent by the first user equipment, the second user equipment can determine that the auxiliary resource set type corresponding to the auxiliary resource set is the auxiliary resource set type of the resource pool where the second user equipment is located.

In one example, the transmission resource pool of user equipment a and the transmission resource pool of user equipment B are in the same resource pool. Assuming that the sequence number of the sending pool is 1, the pre-configured auxiliary resource set of the resource pool with sequence number 1 is referred resource set. User equipment a provides preferred resource set to user equipment B.

The first user equipment needs to acquire the auxiliary resource set type of the second sending resource pool, and determines the auxiliary resource set type for subsequently providing the auxiliary resource set to the second user equipment based on the acquired auxiliary resource set type of the second sending resource pool.

In one example, the transmission resource pool of user equipment a and the transmission resource pool of user equipment B are in different resource pools. For example, the sequence number of the transmission resource pool of the user equipment a is 1, and the sequence number of the transmission resource pool of the user equipment B is 2. The user equipment A configures the non-preferred resource set by acquiring the auxiliary resource set type configuration information of the sending resource pool of the user equipment B. User equipment a provides non-preferred resource sets to user equipment B.

In this embodiment of the disclosure, when determining the auxiliary resource set type provided to the second user equipment based on the auxiliary resource set type of the second sending resource pool, the first user equipment needs to perform communication interaction with the second user equipment to obtain the auxiliary resource set type of the second sending resource pool, and determine the auxiliary resource set type corresponding to the second sending resource pool as the auxiliary resource set type for subsequently providing the auxiliary resource set.

For example, the serial number of the TX pool is 1, the resource pool with the serial number of 1, and the configured auxiliary resource set is referred to as a preferred resource set. And if the resource set is non-predicted resource set, the resource set perceived by the UE B is a difference set with the non-predicted resource set, namely the non-predicted resource set is excluded from the resource set perceived by the UE B.

Example two: the UEA needs to acquire configuration information of a sending resource pool of the UEB and provides an auxiliary resource set according to a pre-configured resource set type of the sending resource pool of the UEB; and the UEB executes corresponding resource selection behaviors according to the resource set type configured by the self-sending resource pool.

Wherein, the UEB carries the sending resource pool configuration information (including the auxiliary resource set type) of the UEB and/or the auxiliary resource set type configuration information of the sending resource pool of the UEB in the auxiliary request. Or through high-level signaling, after the ue a and the ue b exchange signaling, the ue a obtains the resource pool where the ue b is located and the configuration information of the resource pool auxiliary resource set type.

For example, the transmission resource pool of ue a and the transmission resource pool of ue b are in different resource pools. For example, the sequence number of the transmission resource pool of the ue a is 1, and the sequence number of the transmission resource pool of the ue b is 2. And the UE A acquires the auxiliary resource set type configuration information of the transmission resource pool of the UE B as non-predicted resource set, and the UE A provides the non-predicted resource set to the UE B. The UEB also knows that it received a non-predicted resource set, and the UEB intersects the perceived resource set with the predicted resource set.
