detailed description

The technical solutions in the embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

The symbol "/" in this document represents the relationship that the associated object is or, for example, A/B represents A or B.

The terms "first" and "second" in the specification and claims of the present disclosure are used to distinguish different objects, rather than to describe a specific order of objects. For example, the first mode and the second mode are used to distinguish different modes, not to describe a specific order of modes.

In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used as examples, illustrations, or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as being more advantageous than other embodiments or design solutions. To be precise, words such as "exemplary" or "for example" are used to present related concepts in a specific manner.

In the description of the embodiments of the present disclosure, unless otherwise specified, the meaning of “multiple” refers to two or more than two, for example, multiple beams refers to two or more than two beams.

The following explains some terms/nouns involved in the embodiments of the present disclosure.

MBMS: It is a service introduced by 3GPP in order to effectively utilize mobile communication network resources to support the provision of broadcast or multicast services in mobile communication networks. Specifically, the network device may send downlink service data and control information corresponding to the downlink service data to the receiving device in a broadcast/multicast manner, that is, one data source may send the same data to multiple receiving devices. The MBMS service can not only realize the message-type multicast and broadcast of plain text and low rate, but also realize the multicast and broadcast of high-speed multimedia services.

Multi-beam data transmission technology: refers to the technology that network equipment transmits multiple beams in different spatial directions in order to provide better network downlink coverage. It mainly includes two multi-beam data transmission methods. Among them, the first multi-beam data transmission method is: the network device can send the same data packet in different spatial directions at different times by beam scanning. For example, in slot1 and slot2, the network device can be in two The same data packet is sent in different spatial directions; the first multi-beam data transmission method is: network equipment can send the same data packet at the same time and in different spatial directions through multiple beams. For example, in slot1, the network equipment can separately Send the same data packet in multiple different spatial directions.

It should be noted that in related technologies, the user plane layer 2 (L2) protocol stack for receiving MBMS data can usually include the radio link control (RLC) layer and medium access control (medium access). control, MAC) layer, but does not include the packet data convergence protocol (PDCP) layer. When the network device adopts the multi-beam data transmission technology to send multiple identical MBMS data packets in different spatial directions, the receiving device will receive the multiple identical MBMS data packets. Since the MBMS data packet does not have a PDCP layer, the receiving device does not have a duplicate data packet detection mechanism, and will submit multiple identical MBMS data packets to a higher layer, which may cause application processing errors.

In the data receiving method and device provided by the embodiments of the present disclosure, the receiving device can obtain repeated configuration information, which is used to instruct the sending device to repeatedly send data packets; and according to the repeated configuration information, receive the repeatedly sent data packets. With this solution, since the sending device can configure the receiving device with configuration information that indicates the repeated transmission of data packets, when the sending device repeatedly sends multiple identical data packets, the receiving device can perform multiple data packets based on the configuration information. receive. For example, the receiving device can ignore other data packets except the one successfully received among the multiple identical data packets, thereby reducing the power consumption of the receiving device; in addition, the receiving device may not need to submit duplicate data packets to High-level, which can avoid application processing errors.
