Background

In order to effectively utilize mobile communication network resources, a Multimedia Broadcast Multicast Service (MBMS) has been proposed, which supports providing a broadcast or multicast service in a mobile communication network.

Currently, a network device may transmit data packets of the same MBMS in different spatial directions at different times by means of beam scanning (beam scanning), for example, in slot (slot)1 and slot2, and the network device may transmit data packets of the same MBMS in two different spatial directions. Alternatively, the network device may transmit the same MBMS data packet in different spatial directions at the same time through multiple beams, for example, in slot1, and the network device may transmit the same MBMS data packet in different spatial directions, respectively.

However, the receiving device (e.g., User Equipment (UE)) receives multiple identical packets at the same time, which causes additional power consumption problem. In addition, if the receiving device receives the same data packets from multiple different directions, repeated delivery of the data packets to higher layers may cause processing errors for the application.

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 term "and/or" herein is an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The symbol "/" herein denotes a relationship in which the associated object is or, for example, a/B denotes a or B.

The terms "first" and "second," and the like, in the description and in the claims of the present invention are used for distinguishing between different objects and not for describing a particular order of the objects. For example, the first and second manners, etc. are for distinguishing between different manners and not for describing a particular order of the manners.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "such as" in an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the description of the embodiments of the present invention, unless otherwise specified, "a plurality" means two or more, for example, a plurality of beams means two or more beams, and the like.

Some terms/nouns referred to in the embodiments of the present invention are explained below.

MBMS: is a service that supports a broadcast or multicast service provided in a mobile communication network, which is introduced by 3GPP in order to effectively utilize resources of the mobile communication network. Specifically, the network device may send the downlink service data and the 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 implement not only pure text low-rate message multicast and broadcast, but also multicast and broadcast of high-speed multimedia service.

Multi-beam data transmission techniques: the present invention relates to a technology for a network device to transmit multiple beams in different spatial directions in order to provide better downlink coverage of a network, and mainly includes two multi-beam data transmission modes. The first multi-beam data transmission mode is as follows: the network device may send the same data packet in different spatial directions at different times by means of beam scanning, for example, in slots and slots 2, the network device may send the same data packet in two different spatial directions; the first multi-beam data transmission mode is as follows: the network device may transmit the same data packet in different spatial directions at the same time through multiple beams, for example, in a slot, and the network device may transmit the same data packet in different spatial directions, respectively.

It should be noted that, in the related art, a user plane layer two (layer 2, L2) protocol stack for receiving MBMS data may generally include a Radio Link Control (RLC) layer and a Medium Access Control (MAC) layer, but does not include a Packet Data Convergence Protocol (PDCP) layer. When a network device uses a multi-beam data transmission technology to transmit a plurality of identical MBMS data packets in different spatial directions, a receiving device receives the plurality of identical MBMS data packets. Since the MBMS data packet does not have the PDCP layer, the receiving device does not have a duplicate packet detection mechanism and delivers the multiple identical MBMS data packets to the higher layer, which may cause processing errors of the application program.

According to the data receiving method and the data receiving device provided by the embodiment of the invention, the receiving device can obtain the repeated configuration information, and the repeated configuration information is used for indicating the sending device to repeatedly send the data packet; and receiving the repeatedly transmitted data packet according to the repeated configuration information. With this arrangement, since the transmitting apparatus can configure the receiving apparatus with the configuration information for instructing to repeatedly transmit the data packet, when the transmitting apparatus repeatedly transmits a plurality of identical data packets, the receiving apparatus can receive the plurality of data packets according to the configuration information. For example, the receiving apparatus may ignore other packets than the one that is successfully received among the plurality of identical packets, so that power consumption of the receiving apparatus may be reduced; in addition, the receiving device may not need to deliver duplicate packets to higher layers, so that processing errors of the application may be avoided.

The data receiving method and the data receiving equipment provided by the embodiment of the invention can be applied to a communication system. The method can be particularly applied to the scene that the receiving device receives the data packet.

Fig. 1 is a schematic diagram illustrating an architecture of a communication system according to an embodiment of the present invention. As shown in fig. 1, the communication system may include a receiving apparatus 01 and a transmitting apparatus 02. Wherein a connection can be established between the receiving device 01 and the transmitting device 02.

In the embodiment of the present invention, the receiving device 01 and the sending device 02 shown in fig. 1 may be connected wirelessly.

In addition, fig. 1 is an exemplary illustration in which the receiving device is a UE and the transmitting device is a network device, which does not limit the embodiments of the present invention and may be determined according to actual use requirements. It is understood that, in practical implementation, the receiving device may be a UE, or a network device, or other possible receiving devices, etc.; the sending device may be a network device, or a UE, or other possible sending devices, etc.

A UE is a device that provides voice and/or data connectivity to a user, a handheld device with wired/wireless connectivity, or other processing device connected to a wireless modem. A UE may communicate with one or more core network devices via a Radio Access Network (RAN). The UE may be a mobile terminal such as a mobile phone (or "cellular" phone) and a computer having a mobile terminal, or a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device that exchanges speech and/or data with the RAN, such as a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), and so on. The UE may also be referred to as a user agent (user agent) or a terminal device, etc.

A network device is a device deployed in a RAN for providing wireless communication functions for a UE. In the embodiment of the present invention, the network device may be a base station, and the base station may include various macro base stations, micro base stations, relay stations, access points, and the like. In systems using different radio access technologies, the names of devices with base station functionality may differ. For example, in a (5-generation, 5G) system, it may be referred to as a 5G base station (gNB); in a fourth generation wireless communication (4-generation, 4G) system, such as a Long Term Evolution (LTE) system, it may be called an evolved NodeB (eNB); in a third generation (3-generation, 3G) system, it may be referred to as a base station (Node B). As communication technology evolves, the name "base station" may change.

The following describes in detail a data receiving method, a device and a system according to an embodiment of the present invention with reference to the drawings and a specific embodiment and an application scenario thereof.

Based on the communication system shown in fig. 1, an embodiment of the present invention provides a data receiving method. As shown in fig. 2, the data receiving method may include S201 to S203 described below.

Optionally, the data packet repeatedly sent by the sending device may be a plurality of same service data packets, or a plurality of same control data packets corresponding to the service data, or other possible data packets, and the like.

Alternatively, the data packet repeatedly transmitted by the transmitting device may be a data packet of an MBMS, or other data packets that may be repeatedly transmitted. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Specific implementation manners of the configuration manner of the repeated configuration information will be described in the following embodiments, and are not described herein again.

S202, the receiving equipment acquires the repeated configuration information.

In the embodiment of the present invention, after the sending device sends the duplicate configuration information to the receiving device, the receiving device may receive the duplicate configuration information configured by the sending device.

Optionally, a possible implementation manner is that the receiving device may immediately start receiving the data packet according to the received repeated configuration information. Another possible implementation manner is that the receiving device may store the duplicate configuration information in the receiving device first, and in some cases, start receiving the data packet according to the stored duplicate configuration information.

And S203, the receiving equipment receives the repeatedly transmitted data packet according to the repeated configuration information.

It should be noted that, for a specific implementation manner of "the receiving device receives the repeatedly transmitted data packet according to the repeated configuration information", the following embodiments will be described, and details are not described here.

In the data receiving method provided by the embodiment of the present invention, the receiving device may obtain the repeated configuration information, where the repeated configuration information is used to instruct the sending device to repeatedly send data packets; and receiving the repeatedly transmitted data packet according to the repeated configuration information. With this arrangement, since the transmitting apparatus can configure the receiving apparatus with the configuration information for instructing to repeatedly transmit the data packet, when the transmitting apparatus repeatedly transmits a plurality of identical data packets, the receiving apparatus can receive the plurality of data packets according to the configuration information. For example, the receiving apparatus may ignore other data packets than the one that is successfully received among the plurality of identical data packets, so that power consumption of the receiving apparatus may be reduced; in addition, the receiving device may not need to deliver duplicate packets to higher layers, so that processing errors of the application may be avoided.

The time domain configuration information, the frequency domain configuration information, the spatial domain configuration information, and the code domain configuration information will be described below by (1) to (4) below, respectively.

(1) The duplicate configuration information includes: time domain configuration information.

Optionally, the configuration manner of the time domain configuration information may include any one of the first manner and the second manner. The first mode may be configured by time domain position information, and the second mode may be configured by a bitmap.

For the first mode

In this embodiment of the present invention, the time domain position information may be used to indicate a time domain position or a time position of repeatedly transmitting the data packet.

Optionally, the time domain location information may be used to indicate at least one of: and repeatedly transmitting the time domain position and the single time transmission time domain position.

Optionally, the repeatedly sending time domain position may also be referred to as: the transmission time position or the repetition period is repeated. In the repeated sending time domain position, the sending device may repeatedly send the same data packet K times, that is, the repeated sending time domain position is a time domain resource occupied by repeatedly sending K same data packets. Wherein K is a positive integer.

Optionally, the repeatedly transmitting time domain position may include a plurality of time positions, and some or all of the time positions may be used for repeatedly transmitting the data packet. Wherein, one time position may be one slot.

Illustratively, as shown in fig. 3, the repeatedly transmitted time domain position may include 8 slots. slot1 and slot2 may be used to transmit 1 data packet, slot3 and slot4 may be used to transmit 1 data packet, slot5 and slot6 may be used to transmit 1 data packet, and these 3 data packets are the same data packet. That is, in the repeated transmission time domain position, the transmitting device may repeatedly transmit the packet 3 times.

It should be noted that, in the embodiment of the present invention, the data packets sent at different repeated sending time domain positions may be the same data packet or different data packets. For example, in the 1 st retransmission time domain position, the transmitting device may repeat transmitting packet 13 times; in the 2 nd repeat transmission time domain position, the transmitting device may repeat transmitting packet 13 times. For another example, in the 1 st retransmission time domain position, the transmitting device may repeat transmitting data packet 13 times; in the 2 nd repeat transmission time domain position, the transmitting device may repeat transmitting packet 23 times. The method and the device can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Optionally, the single-transmission time domain position may also be referred to as: a single transmission time location or a single transmission period. In a single-transmission time domain position, the transmitting device may transmit one data packet, that is, a single-transmission time domain position is a time domain position occupied by transmitting one data packet at a time.

Alternatively, one single-transmission time-domain location may include at least one time location. Wherein, one time position may be one slot.

Optionally, in a case where one single-transmission time domain position includes a plurality of time positions, the plurality of time positions may be continuous time positions or discrete time positions.

For example, as shown in fig. 3, in 1 repeated transmission time domain position, the transmitting device may transmit 1 data packet at slot1 and slot2, repeatedly transmit the 1 data packet at slot3 and slot4, and repeatedly transmit the 1 data packet at slot5 and slot 6. That is, in 1 repeated transmission time domain position, the 1 st single transmission time domain position is slot1 and slot2, the 2 nd single transmission time domain position is slot3 and slot4, and the 3 rd single transmission time domain position is slot5 and slot 6.

For example, in the repeated transmission time domain position, the transmitting device may transmit 1 data packet at slot1 and slot3, and repeatedly transmit the 1 data packet at slot5 and slot 7. That is, in the repeated transmission time domain positions, the 1 st single transmission time domain positions are slot1 and slot3, and the 2 nd single transmission time domain positions are slot5 and slot 7.

Optionally, in the case that the time domain location information is used to indicate a repeatedly transmitted time domain location, the time domain location information may also be used to indicate: the start position offset of the time domain position is repeatedly transmitted.

Optionally, the starting position offset of the repeatedly transmitted time domain position may also be referred to as: the offset of the start position of the repetition period, and the offset of the start time domain position of the repeated transmission of the data packet.

Illustratively, the System Frame Number (SFN) 1 and slot1 may be the starting time domain positions of the repeated transmission of the data packet in the repeated transmission time domain positions.

Optionally, in the case that the time domain location information is used to indicate a single-transmission time domain location, the time domain location information may also be used to indicate: a start position offset of the time domain position is sent a single time.

Optionally, the starting position offset of the single-transmission time domain position may also be referred to as: the offset of the starting position of the single transmission period, the offset of the starting time domain position of the single transmission time domain resource and the offset of the starting time position of the single transmission time domain resource.

For example, as shown in fig. 3, in 1 repeated transmission time domain position, slot1 may be the starting time position of the 1 st single transmission time domain position, slot3 may be the starting time position of the 2 nd single transmission time domain position, and slot5 may be the starting time position of the 3 rd single transmission time domain position.

Optionally, the starting position offset of the single-transmission time domain position may be obtained by: at the starting time position of the repeated transmission time domain position, x time positions are shifted (i.e., increased or decreased). Wherein x is a positive integer.

For example, assume SFN 1 and slot1 are the starting time positions of the repeated transmission time domain positions. As shown in fig. 3, of the 1 st repeated transmission time domain position, the starting time position of the 1 st single transmission time domain position is slot 1. If the time domain position is shifted by 2 slots from the start time position of the repeated transmission time domain position, the start time position of the 2 nd single transmission time domain position is slot 3. If the time domain position is shifted by 4 slots from the start time position of the repeated transmission time domain position, the start time position of the 3 rd single transmission time domain position is slot 5.

For the second mode

Optionally, each bit in the bitmap is used to indicate at least one of: a particular time domain location, initial data transmission or repeated data transmission, whether the same data transmission.

Optionally, in a case that each bit in the bitmap is used to indicate a specific time domain position, each bit may be specifically used to identify: a particular transmit time domain location, a particular receive time domain location. The specific transmission time domain position may also be referred to as a specific transmission time position, and the specific reception time domain position may also be referred to as a specific reception time position.

For example, the 1 st bit may be used to identify SFN 1 and slot1, the 2 nd bit may be used to identify SFN 1 and slot2, and the transmitting device may transmit 1 data packet at slot1 and slot 2. The 3 rd bit may be used to identify SFN 1 and slot3, the 4 th bit may be used to identify SFN 1 and slot4, and the transmitting device may repeatedly transmit 1 data packet at slot3 and slot 4. The 5 th bit may be used to identify SFN 1 and slot5, the 6 th bit may be used to identify SFN 1 and slot6, and the transmitting device may repeatedly transmit 1 data packet at slot5 and slot 6.

Optionally, when each bit in the bitmap is used to indicate initial data transmission or repeated data transmission, each bit is specifically used to indicate: whether the time position corresponding to each bit is initial data transmission or repeated data transmission.

For example, assume that 1 initial data packet is transmitted at slot1 and slot2, the data packet is repeatedly transmitted at slot3 and slot4, and the data packet is repeatedly transmitted at slot5 and slot 6. If the bit value of "1" indicates initial packet transmission and the bit value of "0" indicates repeated packet transmission, the bitmap may be "110000".

Optionally, when each bit in the bitmap is used to indicate whether the bits are transmitted for the same data, each bit may be specifically used to indicate whether the time positions corresponding to each bit are transmitted for the same data.

For example, assuming that the data packets transmitted on slot1 and slot2 are the same and the data packets transmitted on slot3 and slot4 are the same, the bitmap may be "1100" or "0011".

(2) The duplicate configuration information includes: frequency domain configuration information.

Optionally, the configuration manner of the frequency domain configuration information may include any one of the third manner and the fourth manner. The third mode may be configured by frequency domain interval information, and the fourth mode may be configured by a bitmap.

For the third mode

Optionally, the frequency domain interval information may be used to indicate at least one of: and repeatedly transmitting the frequency domain interval and the single transmission frequency domain interval.

Optionally, the repeatedly-transmitted frequency domain interval may also be referred to as: the frequency domain interval is repeated. In the repeated transmission frequency domain interval, the transmitting device may repeatedly transmit the data packet for multiple times, that is, the repeated transmission frequency domain interval may be a frequency domain resource occupied by repeatedly transmitting multiple data packets.

Optionally, the repeated transmission frequency domain interval may include a plurality of Physical Resource Blocks (PRBs), and some or all of the PRBs in the plurality of PRBs may be used to repeatedly transmit the data packet.

For example, as shown in fig. 4, the repeated transmission frequency-domain section may include 8 PRBs. PRB 1 and PRB 2 may be used to transmit 1 packet, PRB 3 and PRB 4 may be used to transmit 1 packet, PRB 5 and PRB 6 may be used to transmit 1 packet, and the 3 packets are the same packet. That is, in the repeated transmission frequency domain section, the transmitting apparatus can repeatedly transmit the packet 3 times.

It should be noted that, in this embodiment of the present invention, the data packets sent in different retransmission frequency domain intervals may be the same data packet or different data packets. For example, in the 1 st repetitive transmission frequency domain section, the transmitting apparatus may repeat transmission of packet 13 times; in the 2 nd repetitive transmission frequency domain section, the transmitting apparatus can repeat transmission of the data packet 13 times. For another example, in the 1 st repeated transmission frequency domain interval, the transmission apparatus may repeatedly transmit the data packet 13 times; in the 2 nd repetitive transmission frequency domain section, the transmitting apparatus can repeat transmission of the data packet 23 times. The method and the device can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Optionally, in a single transmission frequency domain resource, the transmitting device may transmit a data packet, that is, a single transmission frequency domain interval is a frequency domain interval occupied by transmitting a data packet at a single time.

Optionally, one single-transmission frequency-domain interval may include at least one PRB.

Optionally, when one single-transmission frequency domain interval includes multiple PRBs, the multiple PRBs may be continuous PRBs or may also be discrete PRBs.

For example, as shown in fig. 4, in the frequency domain interval of repeated transmission, the transmitting device may transmit 1 data packet in PRB 1 and PRB 2, transmit the 1 data packet in PRB 3 and PRB 4, and transmit the 1 data packet in PRB 5 and PRB 6. That is, in the repeated transmission frequency domain resource, the 1 st one-time transmission frequency domain section is PRB 1 and PRB 2, the 2 nd one-time transmission frequency domain section is PRB 3 and PRB 4, and the 3 rd one-time transmission frequency domain section is PRB 5 and PRB 6.

For example, in the repeated transmission frequency domain section, the transmission apparatus may transmit 1 data packet in PRB 1 and PRB 3, and repeatedly transmit the 1 data packet in PRB 5 and PRB 7. That is, in the repeated transmission frequency domain section, the 1 st single transmission frequency domain section is PRB 1 and PRB 3, and the 2 nd single transmission frequency domain section is PRB 5 and PRB 7.

Optionally, when the frequency domain interval information is used to indicate that the frequency domain interval is repeatedly transmitted, the frequency domain interval information may also be used to indicate: the start position offset of the frequency domain interval is repeatedly transmitted.

Optionally, the offset of the starting position of the repeatedly transmitted frequency domain interval may also be referred to as: the offset of the starting frequency domain position of the repeated frequency domain interval and the offset of the starting frequency domain position of the repeated data packet sending.

For example, PRB 1 may be a starting frequency-domain position of repeated transmission of a data packet in a repeated transmission frequency-domain interval.

Optionally, in a case that the frequency domain interval information is used to indicate the frequency domain resource for single transmission, the frequency domain interval information may also be used to indicate: the starting position offset of the single transmission frequency domain interval.

Optionally, the offset of the starting position of the single-transmission frequency domain interval may also be referred to as: the offset of the starting frequency domain position of the frequency domain interval is transmitted once.

For example, as shown in fig. 4, in the repeated transmission frequency domain section, the PRB 1 may be the starting position of the 1 st single transmission frequency domain section, the PRB 3 may be the starting position of the 2 nd single transmission frequency domain section, and the PRB 5 may be the starting position of the 3 rd single transmission frequency domain section.

Optionally, the offset of the starting position of the single-transmission frequency domain interval may be obtained by: at the start position of the repeated transmission frequency domain section, y PRBs are offset (i.e., increased or decreased). Wherein y is a positive integer.

For example, PRB 1 is assumed as the start position of the repeated transmission frequency domain interval. As shown in fig. 4, in the repeated transmission frequency domain section, the starting position of the 1 st single transmission frequency domain section is PRB 1. If the start position of the repeated transmission frequency domain interval is shifted by 2 PRBs, the start position of the 2 nd single transmission frequency domain interval is PRB 3. If the start position of the 3 rd single transmission frequency domain section is shifted by 4 PRBs from the start position of the repeated transmission frequency domain section, the start position of the 3 rd single transmission frequency domain section is PRB 5.

For the fourth mode

Optionally, each bit in the bitmap may be used to indicate at least one of: a particular frequency domain location, initial data transmission or repeated data transmission, whether the same data transmission.

Optionally, in a case that each bit in the bitmap is used to indicate a specific frequency domain position, each bit may be specifically used to identify: a particular transmit frequency domain location, a particular receive frequency domain location.

For example, the 1 st bit may be used to identify PRB 1, the 2 nd bit may be used to identify PRB 2, and the transmitting device may transmit 1 data packet in PRB 1 and PRB 2. The 3 rd bit may be used to identify PRB 3, the 4 th bit may be used to identify PRB 4, and the transmitting device may repeatedly transmit the 1 data packet at PRB 3 and PRB 4.

Optionally, repeatedly sending the location identifier of the spatial domain resource may include at least one of: the identification of the target object and the control channel identification corresponding to the target object. Wherein the target object is a beam or a transmission node.

Since the transmission node may be configured to transmit a signal (or a data packet), the receiving device may receive one data packet of a plurality of identical data packets according to an identifier of the transmission node or a control channel identifier corresponding to the transmission node.

For example, the transmitting device may schedule PDCCH 1 to transmit data packet 1 via RNTI 1 and may schedule PDCCH 2 to transmit data packet 2 via RNTI 2. The data packet 1 and the data packet 2 are the same data packet.

For example, the transmitting device may encode PDSCH 1 through RNTI 1 to transmit data packet 1 and encode PDSCH 2 through RNTI 2 to transmit data packet 2. The data packet 1 and the data packet 2 are the same data packet.

In the data receiving method provided by the embodiment of the present invention, the sending device configures at least one of time domain configuration information, frequency domain configuration information, space domain configuration information, and code domain configuration information for the receiving device, so that the receiving device can not receive repeatedly transmitted data packets after successfully receiving data packets according to the configuration information.

Optionally, in this embodiment of the present invention, the step S203 may be specifically implemented by a first possible implementation manner or a second possible implementation manner described below.

First possible implementation

Referring to fig. 2, as shown in fig. 5, S203 may pass through S203A described below.

S203A, the receiving device receives a first data packet of the repeatedly transmitted data packets according to the repeated configuration information, and abandons receiving other data packets of the repeatedly transmitted data packets.

It should be noted that the first data packet may be a data packet transmitted on a specific resource.

Alternatively, assuming that the sending device repeatedly sends a plurality of identical data packets on a plurality of resources, and the first data packet is a data packet transmitted on a specific resource of the plurality of resources, the receiving device may receive the first data packet on the specific resource according to the repeated configuration information, and abandon receiving data packets transmitted on other resources of the plurality of resources.

Illustratively, the transmitting device may transmit packet 1 on a first resource, packet 2 on a second resource, and packet 3 on a third resource, with packet 1, packet 2, and packet 3 being the same packet. The receiving device may select to receive the data packet 1 on the first resource, and to abandon receiving/stopping receiving the data packet 2 transmitted on the second resource, and to abandon receiving/stopping receiving the data packet 3 transmitted on the third resource, according to the obtained duplicate configuration information. That is, the receiving device may receive the first packet transmitted on a particular resource and discard from receiving packets transmitted on other resources.

According to the data receiving method provided by the embodiment of the invention, the receiving equipment receives one data packet transmitted on a specific resource and abandons the reception of data packets transmitted on other resources, so that the power consumption of the receiving equipment can be reduced, and processing errors of an application program caused by delivering a plurality of repeated data packets to a high layer can be avoided.

Second possible implementation

Referring to fig. 2, as shown in fig. 6, S203 may be S203B described below.

S203B, the receiving device receives a plurality of data packets in the repeatedly transmitted data packets according to the repeated configuration information, and abandons (abandon) or discards (ignore) the other data packets in the plurality of data packets when receiving one data packet in the plurality of data packets.

It should be noted that "reception completed" refers to successful reception of the data packet, i.e. the data packet is correctly received and successfully decoded.

The "one packet" may be any one of a plurality of packets.

Illustratively, the transmitting device may transmit packet 1 on a first resource, packet 2 on a second resource, and packet 3 on a third resource, with packet 1, packet 2, and packet 3 being the same packet. The receiving device may receive the data packets transmitted on the three resources according to the obtained duplicate configuration information. If the receiving device successfully receives packet 1 on the first resource, the receiving device may drop receiving packet 2 on the second resource, drop receiving packet 3 on the third resource, and deliver the decoded packet 1 to higher layers. That is, the receiving device may, in the event that reception of one of the plurality of data packets is completed, forgo reception of the other of the plurality of data packets.

For example, the transmitting device may transmit data packet 1 on the first resource, transmit data packet 2 on the second resource, and transmit data packet 3 on the third resource, and data packet 1, data packet 2, and data packet 3 are the same data packet. The receiving device may receive the data packets transmitted on the three resources according to the obtained duplicate configuration information. If the receiving device receives packet 1 on the first resource, receives packet 2 on the second resource, receives packet 3 on the third resource, and successfully decodes packet 1, the receiving device may discard packets 2 and 3 and deliver decoded packet 1 to a higher layer. That is, the receiving device may discard receiving other data packets of the plurality of data packets if receiving one data packet of the plurality of data packets is completed.

According to the data receiving method provided by the embodiment of the invention, under the condition that the repeated data packets are received, the receiving equipment can ignore the repeatedly received data packets through a detection mechanism. It is therefore possible to reduce the power consumption of the receiving device and avoid delivering multiple duplicate packets to higher layers causing processing errors in the application.

Optionally, since the receiving device may repeatedly perform the receiving process of the data packet in the foregoing embodiment, when the receiving device may receive a plurality of different data packets, as shown in fig. 7 in combination with fig. 2, the data receiving method provided in the embodiment of the present invention may further include S204 described below.

S204, under the condition that the receiving equipment receives a plurality of different data packets, the receiving equipment transmits the plurality of different data packets to the upper layers (upperlayers) according to the sequence of the receiving time of the plurality of different data packets.

In the embodiment of the present invention, the upper layer may be layer three (layer 3, L3).

Optionally, the plurality of different data packets may be data packets received through a user plane layer two protocol stack. The user plane layer two protocol stack can be an RLC layer, an MAC layer and a PDCP layer.

For example, it is assumed that the receiving device receives the data packet a, the data packet b, and the data packet c sequentially through a layer two protocol stack, and the data packet a, the data packet b, and the data packet c are different data packets. The receiving device may deliver the data packet a, the data packet b, and the data packet c to the higher layer in the order of the receiving time of the 3 data packets.

The data receiving method provided by the embodiment of the invention is different from the related technology in that a plurality of different data packets are transmitted to a high layer according to the number sequence of the plurality of different data packets.
