Description

Data transmission method and device, data receiving method and device, and electronic device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a data transmission method, a data transmission apparatus, a data reception method, a data reception apparatus, and an electronic device.

Background

At present, in order to solve the problem of reliability of data packet and signaling packet transmission, a scheme of copying a data packet and a signaling packet of a PDCP (packet data convergence protocol) layer at a user equipment side is mainly adopted. However, since the PDCP layer is located at the top layer of the protocol stack on the wireless device side, duplicate packets of the PDCP layer cannot be guaranteed to be transmitted on the bottom layer through two carriers, which may result in poor signal quality on the same carrier, and the probability of successful transmission of duplicate packets if they are still transmitted on the carrier is low.

In order to solve the problem, a method for combining a duplicate packet of the PDCP layer with a carrier is proposed, that is, one PDCP layer is mapped to different logical channels by establishing split bearer (bearer separation), and then mapped to different carriers to be sent to the base station.

One problem with this approach is that since the logical channel is bonded to the carrier to which it is mapped, if the carrier bonded to the logical channel experiences congestion or link problems, the logical channel will not be able to transmit data.

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 application.

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.

Fig. 1 is a schematic flow chart illustrating a data transmission method according to an exemplary embodiment, which may be applied to a user device, such as a mobile phone, a tablet computer, and the like. As shown in fig. 1, the method includes the following steps.

S1, first information sent by the base station is received, and the first information comprises configuration information.

In an embodiment, the base station may be a base station corresponding to any cell of the same cell group (cell group) corresponding to the user equipment, for example, a base station corresponding to a primary cell or a secondary cell in a cell group.

S2, creating a first RLC (Radio Link Control protocol) entity and a second RLC entity according to the configuration information, where the first RLC entity corresponds to the first logical channel and the second RLC entity corresponds to the second logical channel.

In one embodiment, the first RLC entity may correspond to the first logical channel and the second RLC entity may correspond to the second logical channel by marking the first RLC entity as associated with the first logical channel and the second RLC entity as associated with the second logical channel.

S3, the PDCP packet is copied to a copied packet, the PDCP packet is mapped to the first logical channel through the first RLC entity, and the copied packet is mapped to the second logical channel through the second RLC entity.

In one embodiment, the PDCP packet may include a data packet of the PDCP layer and may further include a signaling packet of the PDCP layer. If both the data packet and the signaling packet are included, step S3 copies the data packet and the signaling packet, respectively, and the copied packets may include two packets copied in this process.

As shown in fig. 2, a first RLC entity and a second RLC entity may be created in the RLC layer and configured to correspond to the first logical channel and the second RLC entity to the second logical channel through step S2; then, the data packets and/or the signaling packets of the PDCP layer are copied into duplicate packets, and then the data packets and/or the signaling packets are mapped to the first logical channel by the first RLC entity and the duplicate packets are mapped to the second logical channel by the second RLC entity, through step S4. Thereby creating a load bearing split, i.e. split bear.

S4, transmitting a buffer status report including buffer information of the first logical channel and the second logical channel to the base station, and receiving second information returned by the base station, where the second information includes allocation information of carrier resources generated according to the buffer status report.

In one embodiment, the Buffer Status Report (BSR) may include buffer information of other logical channels in addition to the buffer information of the first logical channel and the second logical channel. According to the buffer status report, the base station may allocate uplink resources to the currently available carriers, so that the carriers can satisfy that sufficient resources can be available to carry data to be transmitted (including PDCP packets and duplicate packets, and may also include other data) after the first logical channel or the second logical channel is mapped thereto.

S5, obtaining constraint information in the first information and/or the second information, and generating a constraint relationship according to the constraint information, where the constraint relationship is used to limit that the first logical channel and the second logical channel are respectively mapped to different carriers.

In an embodiment, the first information may include constraint information in addition to the configuration information, and the constraint information may be independent of the configuration information, or may be included in the configuration information, for example, bearer configuration information that may be included in the configuration information, or MAC layer configuration information that may be included in the configuration information. And/or the second information may include constraint information in addition to the assignment information, and the constraint information may be independent of the assignment information or may be included in the assignment information.

In an embodiment, in the case that the first information includes constraint information, and the second information does not include constraint information, the base station may carry constraint information for defining mapping of different logical channels to different carriers, and may also carry configuration information for indicating how a bearer is configured and how a MAC layer is configured, in the first information sent to the user equipment in step S1, for example, indicating RLC entities associated with other logical channels; the second information sent to the ue in step S4 carries allocation information used for indicating an allocation result of uplink resources of the ue carrier, for example, the allocation information may include an UL grant (uplink grant, which may also be referred to as an uplink grant) used for indicating which timeslots in the carrier are used for transmitting uplink data of the ue.

In this case, the constraint information may be included in the bearer configuration information of the configuration information, or may be located in the MAC layer configuration information of the configuration information.

For example, the constraint information is included in the bearer configuration information, the user equipment may configure the first logical channel and the second logical channel according to the constraint relationship by configuring the bearer. In this case, step S5 may be performed between step S4 and step S6 in the execution order shown in fig. 1, or the execution order of step S5 may be adjusted as necessary, as long as step S5 is guaranteed to be performed between step S2 and step S6.

For example, the constraint information is included in the MAC layer configuration information, the user equipment may generate the constraint relationship between the first logical channel and the second logical channel before allocating resources on the carrier for the logical channel through the MAC layer according to the MAC layer configuration information. In this case, step S5 is performed between step S4 and step S6 in the execution order shown in fig. 1.

In an embodiment, in the case that the second information includes constraint information, and the first information does not include constraint information, the base station may carry constraint information for limiting mapping of different logical channels to different carriers, and may also carry allocation information for indicating an allocation result of uplink resources of carriers of the user equipment in the second information sent to the user equipment in step S4, for example, the allocation information may include a UL grant for indicating which timeslots in a carrier are used for transmitting uplink data of the user equipment; the configuration information sent to the ue in step S1 is used to indicate how the bearer is configured, and indicate how the MAC layer is configured.

In one embodiment, in a case that the first information includes constraint information, and the second information also includes constraint information, the first information and the second information may respectively include complete constraint information, and then the user equipment may generate a constraint relationship according to the constraint information in the first information, or may generate a constraint relationship according to the constraint information in the second information; the first information may contain a first part of constraint information and the second information may contain a second part of constraint information, and the user equipment may generate the constraint relationship based on the first part of constraint information and the second part of constraint information.

S6, respectively allocating resources of different carriers to the first logical channel and the second logical channel according to the allocation information and the constraint relationship, so as to respectively transmit the PDCP packet and the duplicate packet to the base station via the different carriers.

In an embodiment, the constraint relationship may include a first identifier corresponding to the first logical channel and a second identifier corresponding to the second logical channel, and when the MAC layer allocates the resource of the carrier to the first logical channel, the MAC layer may determine the second logical channel according to the second identifier, and then query whether the resource of the carrier has been allocated to the second logical channel, if the resource of the carrier has not been allocated to the second logical channel, allocate the resource of the carrier to the first logical channel, and allocate the resource of another carrier to the second logical channel; if the second logical channel is allocated with the resources of the carrier wave, the first logical channel is allocated with the resources of other carrier waves.

In an embodiment, the constraint relationship may include mutual exclusion logic information, and when the MAC layer identifies the mutual exclusion logic information when allocating resources on carriers for the logical channels, the MAC layer allocates resources of different carriers for each logical channel.

In an embodiment, according to the constraint relationship, resources of different carriers may be allocated to the first logical channel and the second logical channel, and according to the allocation information, which resources, for example, timeslot resources, in the carriers are used for transmitting uplink data of the user equipment may be determined, so as to determine resources corresponding to the PDCP packet and the duplicate packet on different carriers, respectively, and further perform transmission.

For example, for 3 carriers A, B, C, when the user equipment transmits the PDCP packet and the duplicate packet to the base station at a certain time, the first logical channel is mapped to the a carrier and the second logical channel is mapped to the B carrier; when the user equipment transmits the PDCP packet and the duplicate packet to the base station next time, if it is detected that the a carrier has the congestion or the link, the first logical channel may be mapped to the C carrier, and the second logical channel may be mapped to the B carrier, that is, the PDCP packet and the duplicate packet of the PDCP packet may still be transmitted to the base station through the first logical channel and the second logical channel.

Fig. 3 is a schematic flow chart diagram illustrating another method of data transmission in accordance with an example embodiment. As shown in fig. 3, on the basis of the embodiment shown in fig. 1, the allocating resources of different carriers to the first logical channel and the second logical channel respectively includes:

step S61, when allocating the resource of the first carrier to the first logical channel, determining whether the resource of the first carrier has been allocated to the second logical channel, and if the resource of the first carrier has been allocated to the second logical channel, executing step S62; if the resource of the first carrier is not allocated to the second logical channel, go to step S63;

step S62, allocating resources of a second carrier to the first logical channel;

step S63, allocating the resource of the first carrier for the first logical channel, and allocating the resource of the second carrier for the second logical channel.

In one embodiment, when allocating resources of a first carrier for a first logical channel, if it is detected that resources of a second logical channel have been allocated on the first carrier, then in order to ensure that resources of different carriers are allocated for the first logical channel and the second logical channel, resources of a second carrier different from the first carrier may be allocated to the first logical channel; if it is detected that the second logical channel has not been allocated with resources on the first carrier, then the first logical channel may be allocated with resources directly on the first carrier, and then the second logical channel may be allocated with resources on the second carrier. Therefore, the first logic channel and the second logic channel corresponding to the two RLC entities belonging to the same bearing separation are ensured to allocate resources of different carriers.

Fig. 4 is a schematic flow chart diagram illustrating yet another method of data transmission according to an example embodiment. As shown in fig. 4, based on the embodiment shown in fig. 3 (not all steps in fig. 3), in the case that the first carrier resource is allocated to the first logical channel and the second carrier resource is allocated to the second logical channel, the method further includes:

Step S81, when detecting that the second carrier is not available, determining whether there is another carrier available, and if there is another carrier, executing step S82;

step S82, allocating resources of the other carriers to the second logical channel.

In one embodiment, carrier unavailability may refer to the carrier having congestion, link problems, and the like.

In one embodiment, since the first logical channel and the first carrier are not bonded, when it is detected that the first carrier is not available, available other carriers can be queried, and then resources of the other carriers are allocated to the first logical channel, so as to ensure that the PDCP packet can be successfully transmitted to the base station on the other carriers through the first logical channel.

In one embodiment, since the second logical channel and the second carrier are not bonded, when it is detected that the second carrier is not available, the available other carriers may be queried, and then resources of the other carriers may be allocated to the second logical channel, so as to ensure that the duplicate packet may be successfully transmitted to the base station on the other carriers through the second logical channel.
