Detailed Description

To make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 1 is a schematic diagram of a network structure to which the embodiment of the present invention is applicable, and as shown in fig. 1, the network structure includes a terminal 11 and a network side device 12, where the terminal 11 may be a User Equipment (UE) or other terminal devices, for example: a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), a robot, a vehicle, and other terminal side devices, and it should be noted that the specific type of the terminal is not limited in the embodiment of the present invention. The network side device 12 may be a base station, for example: macro station, LTE eNB, 5G NR NB, etc.; the network side device may also be a small station, such as a Low Power Node (LPN), pico, femto, or the network side device may be an Access Point (AP); the network side device may also be a network node formed by a Central Unit (CU) and a plurality of Transmission Reception Points (TRPs) managed and controlled by the CU. It should be noted that, in the embodiment of the present invention, the specific type of the network-side device is not limited.

In addition, the repeated transmission in the embodiment of the present invention may be applied to repeated transmission in Carrier Aggregation (CA) and Dual Connectivity (DC) including but not limited to those shown in fig. 2.

In CA and DC scenarios, that is, one RB (corresponding to one PDCP entity) of the PDCP layer, transmission is performed through a plurality of Logical channels (RLC entities) respectively in a Radio Link Control (RLC) layer. For the CA model, multiple logical channels corresponding to the repeatedly transmitted RBs are processed by one MAC entity at a Media Access Control (MAC) layer, and data from different RLC logical channels are mapped to one or more carriers for transmission. For the DC model, the PDCP entity may send data corresponding to a Master Cell Group (MCG) to an RLC entity, send data corresponding to a Secondary Cell Group (SCG) to an RLC entity, map a plurality of logical channels corresponding to repeated transmission RBs (duplicate RBs) to different MAC entities, and map data of logical channels corresponding to different RLC entities to different carriers for transmission.

Referring to fig. 3, fig. 3 is a flowchart of a cache information reporting method according to an embodiment of the present invention, and as shown in fig. 3, the method includes the following steps:

301. under the condition that a terminal deactivates repeated transmission to an RB, the terminal reports to a network side device that a buffer of a logical channel group corresponding to a logical channel deactivated by the RB for deactivating repeated transmission is empty, wherein the deactivation repeated transmission is controlled by the terminal.

In the embodiment of the present invention, both the activation repeat transmission and the deactivation repeat transmission of the RB may be controlled by the terminal, that is, the terminal may autonomously decide to activate or deactivate the repeat transmission of the RB, for example: the terminal can determine to activate or deactivate the repeated transmission of one or more RBs according to the terminal capability, service requirement, equipment resource condition and other reasons, so that the terminal capability can be improved, and the terminal transmission mode can be matched with the terminal more, so as to improve the terminal transmission performance.

In addition, in the case that the terminal deactivates the repeated transmission to the RB, the reporting, by the terminal, to the network side device that the buffer of the logical channel group corresponding to the logical channel deactivated by the RB that deactivates the repeated transmission is empty may be that, when the terminal deactivates the repeated transmission to the RB, reporting, to the network side device, buffer information indicating that the buffer of the logical channel group corresponding to the logical channel deactivated by the RB that deactivates the repeated transmission is empty.

Wherein, the reporting that the buffer of the logical channel group corresponding to the logical channel deactivated by the RB that deactivates the repeated transmission is empty may explicitly report that the logical channel is empty, for example: and setting the buffer size field to be 0, or implicitly reporting that the logic channel is empty.

After receiving the buffer report of the terminal, the network side device determines the logical channel configured for repeated transmission in the logical channel group with empty buffer report as the logical channel deactivated by the RB deactivated for repeated transmission, so that the resource scheduling can be performed on the logical channel no longer, and the resource waste is avoided.

In the embodiment of the invention, the terminal can control the repeated transmission deactivation of the RB through the steps so as to improve the capability of the terminal, and the transmission mode of the terminal can be more matched with the terminal so as to improve the transmission performance of the terminal.

As an optional implementation manner, the reporting, by the terminal to a network side device, that a buffer of a logical channel group corresponding to a logical channel deactivated by the RB that deactivates the repeated transmission is empty includes:

The setting of the buffer size field to 0 may indicate that the buffer of the deactivated logical channel is empty, and further may indicate that the buffer configured with the repeatedly transmitted logical channel in the logical channel group is 0, so as to indicate that the logical channel is deactivated to the network side device. Therefore, when the terminal deactivates the repeat transmission for the bearer configured with the repeat transmission, the terminal triggers the Buffer report for the logic channel for deactivating the repeat transmission, and reports the Buffer size of all 0 s on the logic channel group corresponding to the logic channel. In this way, the deactivated logical channel is indicated by the Buffer size, so that no additional signaling is needed, and the signaling format is modified, thereby reducing the complexity. For example: as shown in fig. 4, a first row in the BSR indicates that Logical Channel Group (LCG) 1 and LCG2 (including deactivated Logical channels) are 1, and the remaining LCGs are 0, so as to indicate that data buffers of LCG1 and LCG2 are indicated in the Logical Channel Group indication, and there are no data buffers of the remaining LCGs. The second row shows the buffer size field corresponding to LCG1, and the third row shows the buffer size field corresponding to LCG2.

In addition, the indication of reporting the logical channel group in the logical channel group indication in the BSR may indicate that the BSR reports the data buffer of the logical channel group in the logical channel group indication, and since a buffer size domain does not appear, the reporting indicates that the buffer is empty, so that no signaling needs to be added, and the overhead of the BSR can be saved. So that the network side device can determine the logical channel whose buffer is empty. As shown in fig. 5, in the BSR, the first row indicates that LCG1 and LCG2 (including deactivated logical channels) are 1, and the remaining LCGs are empty (which may also be understood as 0), so as to indicate that data buffers of LCG1 and LCG2 are indicated in the logical channel group indication, and there are no data buffers of the remaining LCGs. In addition, the second row shows the buffer size field corresponding to LCG1, and the buffer size field corresponding to LCG2 does not appear.

As an optional implementation manner, the mapping manner of the logical channel of the RB and the logical channel group is one of the following:

mode 1, different logical channels of the same repeatedly transmitted RB are mapped to different logical channel groups;

and 2, mapping the simultaneously deactivated logical channels in the plurality of RBs capable of simultaneously deactivating the repeated transmission to the same logical channel group.

In the above mode 1, different Logical Channels (LCHs) corresponding to one repeat transmission RB may be mapped to respective independent Logical Channel groups, for example, RB1 corresponds to LCH1 and LCH2, and LCH1 and LCH2 are respectively mapped to LCG1 and LCG2.

In the above mode 1, because different logical channels of the same RB that is repeatedly transmitted are mapped to different logical channel groups, it may be achieved that the corresponding deactivated logical channel is directly indicated by reporting that the buffer size field corresponding to the logical channel group is 0 or does not appear.

The above manner 2 may be to map the logical channels that can be simultaneously deactivated in a group of RBs that can simultaneously deactivate the repeated transmission to the same logical channel group, for example, RB1 and RB2 can simultaneously deactivate the repeated transmission, RB1 corresponds to LCH1 and LCH2, RB2 corresponds to LCH3 and LCH4, where LCH2 and LCH4 can simultaneously deactivate the repeated transmission, LCH1 and LCH3 are mapped to LCG1, and LCH2 and LCH4 are mapped to LCG2.

In the above mode 2, since the simultaneously deactivated logical channels are mapped to the same logical channel group, it may be achieved that the corresponding plurality of deactivated logical channels are directly indicated by reporting that the buffer size domain corresponding to the logical channel group is 0 or does not appear.

As an optional implementation manner, the first logical channel group including the logical channel corresponding to the repeatedly transmitted RB further includes a logical channel corresponding to an RB for which repeated transmission is not configured.

In this embodiment, a third LCH-to-LCG mapping scheme may be implemented: that is, in addition to the above mapping method 1 and method 2, other logical channels not configured with retransmission may be mapped to the same logical channel group as the logical channel configured with retransmission. Alternatively, it may be a further extension of the above-described

modes

1 and 2, for example: in the above-described

modes

1 and 2, the LCG2 may further include a logical channel LCH5 that does not perform repeated transmission.

In this embodiment, the logical channel group includes a logical channel configured with repeated transmission and an unconfigured logical channel, so that the deactivated logical channel can be indicated in the above manner, and since the logical channel configured with repeated transmission is included, the configuration of too many logical channel groups for the terminal is avoided, so as to save overhead.

Further, the reporting, by the terminal to a network side device, that the buffer of the logical channel group corresponding to the logical channel deactivated by the RB that deactivates the repeated transmission is empty may include:

and the terminal reports a first BSR to network side equipment, wherein a buffer size domain corresponding to the first logical channel group in the first BSR is 0 or the buffer size domain does not appear, but reporting of the logical channel group is indicated in the logical channel group indication to represent a deactivated logical channel.

In this embodiment, it may be implemented that the buffer size domain is 0 or the buffer size does not appear, and the report of the logical channel group is indicated in the logical channel group indication to indicate a deactivated logical channel, so that no additional signaling is required, and the overhead of the BSR is reduced. For example: the first BSR may refer to the BSR of fig. 3 or fig. 4.

Further, the method may further include:

The actual buffer size indicated by the second BSR may be a buffer size of a logical channel other than the activated logical channel in the first logical channel group. Therefore, if the logic channel group comprises other logic channels and data caches of the other logic channels besides the logic channels for deactivating repeated transmission, after the first BSR is reported, the BSR reporting is triggered again, and the real cache of the LCG is reported.

It should be noted that, the mapping manner between the logical channels and the logical channel groups may be configured by the network side device to the terminal, but is not limited to this, for example: agreed upon.

As an optional implementation manner, the terminal triggers and reports to the network side device that the buffer of the logical channel group corresponding to the deactivated logical channel is empty, and the BSR can trigger the scheduling request SR.

In this embodiment, the triggering behavior of the BSR described above may be implemented, and the SR may also be triggered, so as to implement timely triggering of the SR, so as to reduce the triggering behavior of the terminal. For example: taking the BSR triggered behavior reporting that the buffer of the deactivated logical channel is 0 as regular (regular) BSR triggering, which may trigger a scheduling request SR.

and the terminal reports that the buffer of the logical channel group corresponding to the logical channel deactivated by the RB for deactivating repeated transmission is empty to the network side equipment on the uplink resource allocated by the network side.

The uplink resource may be configured to the terminal by the network side device before the buffer report.

In the embodiment of the present invention, when a terminal deactivates the repeated transmission to an RB, the terminal reports to a network side device that a buffer of a logical channel group corresponding to a logical channel deactivated by the RB that deactivates the repeated transmission is empty, where the deactivation of the repeated transmission is controlled by the terminal. This may enable the terminal to control the deactivation of the repeated transmission, thereby improving the capability of the terminal.

Referring to fig. 6, fig. 6 is a flowchart of a method for receiving cache information according to an embodiment of the present invention, as shown in fig. 6, including the following steps:

601. the network side equipment receives the cache report of the terminal;

602. and the network side equipment confirms the logical channel configured for repeated transmission in the logical channel group with empty buffer report as the logical channel deactivated by the RB for deactivating the repeated transmission, wherein the deactivation is controlled by the terminal.

Optionally, the receiving, by the network side device, the buffer report of the terminal includes:

the network side equipment receives the BSR reported by the terminal;

Optionally, the first logical channel group including the logical channel corresponding to the repeatedly transmitted RB further includes a logical channel corresponding to an RB without configuration for repeated transmission.

the network side device receives a first BSR reported by the terminal, where a buffer size domain corresponding to the first logical channel group in the first BSR is 0 or the buffer size domain does not appear, but reporting of the logical channel group is indicated in the logical channel group indication to indicate a deactivated logical channel.

Optionally, the method further includes:

It should be noted that, this embodiment is used as an implementation of the network side device corresponding to the embodiment shown in fig. 3, and specific implementation thereof may refer to the relevant description of the embodiment shown in fig. 3, so that, in order to avoid repeated description, this embodiment is not described again, and the same beneficial effects may also be achieved.

The method provided by the embodiment of the present invention is exemplified by taking a network side device as a base station through a plurality of embodiments as follows:

example 1

In this embodiment, the base station configures different logical channels of the repeated transmission RB as separate logical channel groups

A terminal side:

step 1: a terminal receives configuration of repeated transmission RBs sent by a base station side, a logical channel corresponding to each repeated transmission RB, and mapping from the logical channel to a logical channel group, for example, the repeated transmission RB1 corresponds to the logical channels LCH1 and LCH2, the LCG1 corresponds to the LCH1 uniquely, and the LCG2 corresponds to the LCH2 uniquely;

step 2: the terminal determines to deactivate the repeated transmission of the repeated transmission RB1 on the logical channel 2, the data buffer of the LCH2 is 0, the buffer corresponding to the LCG2 is 0, and triggers BSR reporting, where the BSR format is as shown in fig. 4 in the case where only RB1 data is available. In the figure, the Buffer Size domain corresponding to LCG2 is set to all 0, it should be noted that this is not allowed in some related technologies (for example, in the prior art), which is newly defined by the embodiment of the present invention.

The BSR reporting the empty buffer may be reported in one of the following manners:

(1) The behavior triggered by the empty BSR is regarded as a regular BSR trigger, and a scheduling request SR can be triggered; or

(2) The triggered empty BSR can be allocated on the allocated uplink resource only when there is uplink resource allocation.

And step 3: and the terminal receives the uplink resource scheduling allocation of the base station and does not transmit the LCH2 new data.

A base station side:

step 1: the base station sends repeated transmission configuration to the terminal, configures repeated transmission RBs, a logical channel corresponding to each repeated transmission RB, and mapping from the logical channel to a logical channel group, for example, the repeated transmission RB1 corresponds to the logical channels LCH1 and LCH2, the LCG1 corresponds to the LCH1 uniquely, and the LCG2 corresponds to the LCH2 uniquely;

and 2, step: when a specific logical channel group is assigned with a cache report and its corresponding buffer size is set to 0, for example: if the logical channel group is LCG2, it is determined that the logical channel (LCH 2) associated with the repeated transmission RB in the logical channel group does not participate in the repeated transmission, that is, the logical channel does not transmit the repeated transmission data;

and step 3: after determining that the RB and the logic channel for deactivating the repeated transmission are deactivated, the base station does not perform resource scheduling on the logic channel.

Example 2

In this embodiment, the base station maps a group of simultaneously deactivatable logical channels, which may simultaneously deactivate the repeatedly transmitted RBs, to the same logical channel group

A terminal side:

step 1: a terminal receives configuration of repeated transmission RBs sent by a base station side, a logical channel corresponding to each repeated transmission RB, and mapping of the logical channel to a logical channel group, for example, RB1 and RB2 can simultaneously deactivate repeated transmission, RB1 corresponds to LCH1 and LCH2, RB2 corresponds to LCH3 and LCH4, LCH2 and LCH4 can simultaneously deactivate repeated transmission, LCH1 and LCH3 are mapped to LCG1, and LCH2 and LCH4 are mapped to LCG2;

step 2: the terminal determines to deactivate the duplicate transmission bearers RB1 and RB2, deactivate the duplicate transmission of RB1 on LCH2, and deactivate the duplicate transmission of RB2 on LCH4, where the data Buffer of LCH2 and LCH4 is 0, and the Buffer corresponding to LCG2 is 0, and trigger BSR reporting, where only RB1 and/or RB2 data exists, the BSR format is shown in fig. 4, where the Buffer Size domain corresponding to LCG2 is all 0, it needs to be noted that this point is not allowed in some related technologies (e.g., the prior art), which is newly defined by the embodiment of the present invention.

And step 3: and the terminal receives the uplink resource scheduling allocation of the base station and does not transmit new data on the LCH2 and the LCH 4.

A base station side:

step 1: a base station sends repeated transmission configuration to a terminal, configures repeated transmission RBs, a logical channel corresponding to each repeated transmission RB, and mapping of the logical channel to a logical channel group, wherein if the repeated transmission RBs are configured to be RB1 and RB2, the RB1 and RB2 can simultaneously deactivate repeated transmission, the RB1 corresponds to LCH1 and LCH2, the RB2 corresponds to LCH3 and LCH4, the LCH2 and LCH4 can simultaneously deactivate repeated transmission, and then the LCH1 and LCH3 are mapped to LCG1, and the LCH2 and LCH4 are mapped to LCG2;

step 2: when a specific logical channel group is assigned with a cache report and its corresponding buffer size is set to 0, for example: if the logical channel group is LCG2, it is determined that the logical channels (LCH 2 and LCH 4) associated with the repeated transmission RB in the logical channel group do not participate in the repeated transmission, that is, the logical channels do not transmit the repeated transmission data;

and step 3: after determining that the RB1 and the RB2 which are repeatedly transmitted and the logical channels LCH2 and LCH4 which are repeatedly transmitted are deactivated, the base station does not perform resource scheduling on the logical channels.

Example 3

In this embodiment, the base station maps different logical channels of one RB to different logical channel groups, and the logical channel group may also map other logical channels

A terminal side:

step 1: a terminal receives configuration of repeated transmission RBs sent by a base station side, a logical channel corresponding to each repeated transmission RB, and mapping of the logical channel to a logical channel group, for example, the repeated transmission RB1 corresponds to logical channels LCH1 and LCH2, LCH1 is mapped to LCG1, LCH2 is mapped to LCG2, and meanwhile, another logical channel LCH3 bearing RB3 is also mapped to LCG2;

step 2: the terminal determines to deactivate the repeated transmission of the repeated transmission bearer RB1 on the LCH2, then the data Buffer of the LCH2 is 0, the Buffer of the LCG2 is set to 0 (even though there is a data Buffer on the LCH 3), and BSR reporting is triggered, where only the LCG1 and the LCG2 exist, the BSR format is as shown in fig. 4, and the Buffer Size domain corresponding to the LCG2 in the figure is set to all 0, it should be noted that this point is not allowed in some related technologies (for example, the prior art), which is newly defined in the embodiment of the present invention.

(1) The behavior of the empty BSR trigger is regarded as a regular BSR trigger, and a scheduling request SR can be triggered; or

And step 3: and the terminal receives the uplink resource scheduling allocation of the base station and does not transmit the LCH2 new data. Optionally, if the LCH3 has a data buffer, the BSR report is triggered again, and the buffer data volume of the LCH3 is reported in the LCG2.

A base station side:

step 1: the base station sends a repeated transmission configuration to the terminal, configures repeated transmission RBs, a logical channel corresponding to each repeated transmission RB, and mapping from the logical channel to a logical channel group, for example, the repeated transmission RB1 corresponds to logical channels LCH1 and LCH2, the LCH1 is mapped to LCG1, the LCH2 is mapped to LCG2, and simultaneously, another logical channel LCH3 bearing RB3 is also mapped to LCG2;

step 2: a base station receives a buffer report sent by a terminal side, and when a specific logical channel group is designated with the buffer report and the corresponding buffer size is set to 0, for example, the LCG2 indicates an empty buffer in the embodiment, it is determined that a logical channel (LCH 2) associated with a repeated transmission RB in the logical channel group (LCG 2) does not participate in repeated transmission;
