Description

Resource allocation method and device
Technical Field
The present disclosure relates to the field of communications, and in particular, to a method and an apparatus for resource allocation.
Background
5G, NR (New Radio) system related standardization is in progress in 3GPP (3 rd Generation Partnership Project, third generation partnership project).
In LTE (Long Term Evolution ) V2x (Vehicle to Everything, internet of vehicles), a resource pool is used to manage time-frequency resources of a sidlink (object direct connection) communication. One resource pool is a set of periodic time-frequency resources over a given system bandwidth. For the data to be sent, the sending end will send a control message to the receiving end, where the control message may include information such as a multicast address, a location of a time-frequency resource occupied by data transmission, and a modulation coding mode. The transmitting end is configured with a control information resource pool and a data resource pool, and transmits control information through the resources of the control information resource pool and data through the resources of the data resource pool.
Similarly, the receiving end monitors the control information resource pool, and knows whether data transmission exists or not by monitoring the control information sent by the sending end, and receives the data at the position of the resource occupied by the corresponding data.
In LTE, the address in the control information is typically a multicast address, and all physical layer Sidelink communications are multicast or broadcast based. Since multicast and broadcast communications require data to be transmitted to all potential users within communication range, LTE V2x does not support feedback information nor modulation coding adjustment and power control based on receiver feedback. Similarly, the LTE V2x receiving end needs to keep monitoring broadcast information of other user equipments at all times to avoid missing data.

In this step, the first correspondence may be as shown in table 1.
TABLE 1
The transmitting end may determine, according to table 1, a target data resource pool for transmitting target data, where the target data is data that needs to be transmitted to the receiving end.
For example, if the target address type is a unicast address, the transmitting end may select one unicast data resource pool from among unicast data resource pools as the target data resource pool according to table 1. Alternatively, the sender may select an appropriate unicast data resource pool as the target data resource pool according to the number of available resources in each unicast data resource pool. If the target address type is a multicast address, the sender may also select an appropriate multicast data resource pool as the target data resource pool according to table 1.

In the above embodiment, when the base station configures the first correspondence for the transmitting end in the vehicle network and the receiving end in the vehicle network in advance, if the address type is a unicast address, the resources of the unicast control information resource pool and the resources of the unicast data resource pool may be configured respectively based on a time division multiplexing mode, so that the receiving end of the vehicle network only needs to monitor and control the unicast information resource pool, and when there is transmitted unicast data, the receiving end receives the unicast data through the unicast data resource pool, thereby reducing the energy expenditure and complexity of the user equipment. If the address type is a multicast address, the base station configures the resources of the multicast control information resource pool and the resources of the multicast data resource pool respectively based on a frequency division multiplexing mode, and the receiving end can receive the transmitted data while receiving the control information, so that the influence caused by half duplex transmission and reception of the transmitting end and the receiving end is reduced, and the transmission delay is also reduced.
For the above step 302, the base station may send at least one of the first correspondence and the second correspondence to the sending end and the receiving end respectively through downlink signaling. The downlink signaling may include RRC signaling or DCI signaling of a physical layer.

The transmitting end transmits the target control information and/or the target data to the receiving end according to different target transmission modes, and the receiving end receives the target control information and/or the target data according to different target transmission modes.
In the above embodiment, the base station configures the third correspondence for the transmitting end of the vehicle network and the receiving end in the vehicle network, so that the physical layer unicast communication and the multicast communication can be simultaneously supported in the vehicle network.
In the embodiment of the present disclosure, the third correspondence may be written in advance in an underlying protocol of the transmitting end device and the receiving end device, and the transmitting end device and the receiving end device may use a non-cellular network spectrum or may use a pre-configuration when the base station configuration information cannot be received outside the coverage area of the cellular network.
In an embodiment, another resource allocation method is further provided in the embodiment of the present disclosure, and referring to fig. 23, another resource allocation method flowchart is shown according to an exemplary embodiment, and may include the following steps:
in step 401, a base station configures at least one of a first correspondence and a second correspondence for a transmitting end in a vehicle network and a receiving end in the vehicle network; the first corresponding relation is a corresponding relation between a data resource pool and an address type, and the second corresponding relation is a corresponding relation between a control information resource pool and the address type;

In step 403, the base station configures a third correspondence between the transmission mode and the direct link data transmission type for the transmitting end and the receiving end.
In step 404, the base station sends the third correspondence to the sending end and the receiving end through downlink signaling.
In step 405, the sender determines a destination address type corresponding to the direct link data transmission type, where the destination address type is used to indicate that a destination address corresponding to a receiver in the internet of vehicles belongs to a unicast address, a multicast address or a broadcast address.
In step 406, the sending end determines a target data resource pool corresponding to a target address type according to the first correspondence; and/or determining a target control information resource pool for transmitting target control information according to the second corresponding relation between the configured control information resource pool and the address type.
In step 407, the transmitting end determines, according to the third correspondence, a target transmission mode corresponding to the current direct link data transmission type.
In step 408, the transmitting end adopts the target transmission mode, uses the resources in the target data resource pool to transmit the target data, and/or uses the resources in the target control information resource pool to transmit the target control information.
In step 409, the receiving end determines, according to the first correspondence, a target data resource pool for receiving target data; and/or determining a target control information resource pool for receiving target control information according to the second corresponding relation.

In step 412, the receiving end receives the target data corresponding to the direct link data transmission type in the target data resource pool by adopting the target transmission mode corresponding to the direct link data transmission type.
In this step, after the receiving end monitors unicast data, the receiving end receives unicast data in a unicast transmission mode in the unicast data resource pool according to the position indicated by the position indication information included in the unicast control information.
And after the receiving end monitors the multicast data, the receiving end receives the multicast data in a multicast transmission mode in a multicast data resource pool according to the position indicated by the position indication information included in the multicast control information.

And the sending end sends the target control information and the target data to the receiving end through the resources of the target resource pool according to the target transmission mode. And the receiving end monitors target control information in a target control information resource pool according to the target transmission mode and receives target data in a target data resource pool according to the target transmission mode. The physical layer unicast communication and the multicast communication can be simultaneously supported in the Internet of vehicles through configuration of the resource pool. In addition, because unicast communication is supported, the physical layer transmission parameters of the sending end can be adjusted through feedback of the receiving end, so that the communication efficiency is improved. The receiving end can monitor the unicast control information resource pool only in a specific time, thereby reducing the energy expenditure and complexity of the user equipment.
