In a specific implementation, the PDCP copy function is introduced to improve reliability of Ultra Reliable Low Latency Communication (URLLC) service transmission. Specifically, one PDCP packet is duplicated into two identical packets by the PDCP layer at the transmitting end and transmitted by using different radio data links (Leg), respectively. More specifically, the PDCP layer deletes one of the two PDCP packets and reserves only one of the two PDCP packets when the two PDCP packets are successfully received. That is, the same data packet is duplicated into two identical packets and transmitted through two different paths, thereby improving the reliability of data transmission. The PDCP Data packet may include a PDCP Protocol Data Unit (PDU) and a PDCP Service Data Unit (SDU).
However, in the prior art, how many sending end logical channels to be used are used to send the copied PDCP data packets, and which sending end logical channels to be used are used to perform data transmission, are indicated for the UE by signaling at the network side, resulting in a large signaling overhead for achieving more flexible activation/deactivation control.

Detailed Description
In the prior art, Two wireless data link replication (Two-legs replication) mode activation/deactivation mechanisms are supported. Specifically, for each RB in which a copy function is configured, activation or deactivation of the copy function of the RB is indicated by one bit (bit). The copy function activation can be used for instructing the PDCP to perform copy operation, and both wireless data links perform data transmission; the copy function deactivation may be used to instruct the PDCP not to perform a copy operation and to perform data transmission only over a Primary radio data link (Primary leg).
However, for Multi-connection replication (Multi-connection replication), more than two Radio data links (leg) may be configured for a Radio Bearer (RB) configured with a replication function, and it is unclear for one RB how many sending-end logical channels to be used are used to send replicated PDCP packets, and which ones are used to perform data transmission, and it is indicated by one bit. Specifically, one bit contains only 0/1 states, i.e. it can only be used to indicate two wireless data links, and cannot clearly indicate the use of multi-connection duplication.
Referring to fig. 1, fig. 1 is a schematic diagram of an operating scenario of a data transmission method in the prior art, where the data transmission method may be used in a PDCP replication architecture in a Carrier Aggregation (CA) scenario.
In the data transmission method, the sending-end PDCP entity 110 issues PDCP data packets to the first sending-end RLC entity 121 and the second sending-end RLC entity 122, respectively, and issues the PDCP data packets to the sending-end Medium Access Control (MAC) 130 through a first sending-end logical channel corresponding to the first sending-end RLC entity 121 and a second sending-end logical channel corresponding to the second sending-end RLC entity 122.
Since the first transmitting end logical channel and the second transmitting end logical channel are mapped to different cells, the PDCP data packet is transmitted through different cells, for example, the PDCP data packet transmitted by the first transmitting end logical channel is transmitted through the first cell 141 and the second cell 142, and the PDCP data packet transmitted by the second transmitting end logical channel is transmitted through the third cell 143, the fourth cell 144, and the fifth cell 145.
Further, the receiving-side medium access layer 150 receives PDCP data packets through different cells, for example, the first cell 141, the second cell 142, the third cell 143, the fourth cell 144, and the fifth cell 145, and uploads the PDCP data packets to the corresponding first receiving-side RLC entity 161 and the second receiving-side RLC entity 162, and uploads the PDCP data packets to the receiving-side PDCP entity 170 through the first receiving-side logical channel corresponding to the first receiving-side RLC entity 161 and the second receiving-side logical channel corresponding to the second receiving-side RLC entity 162.
In a specific implementation, each radio data link may be one of paths from the sending-end PDCP entity 110 to the receiving-end PDCP entity 170, for example, from the sending-end PDCP entity, the sending-end RLC entity, the sending-end medium access layer, a cell, the receiving-end medium access layer, the receiving-end RLC entity, to the receiving-end PDCP entity.
In the PDCP copy function architecture in the existing CA scenario, multiple steps of configuration, activation, deactivation, etc. may be included to implement the copy function.
Specifically, in the configuring step, the network side (e.g., the base station) may configure a PDCP duplication function for a plurality of Radio Bearers (RBs) by using an RRC message, and establish an additional duplicate RLC entity for the RB. The RRC message also indicates a cell group ID (cell group ID) and a Logical Channel ID (LCID) of the primary RLC entity. The RRC message may also set a copy initial state (e.g., active or inactive) for the RBs.
In the CA scenario, only one MAC entity is typically required. Through a Radio Resource Control (RRC) message, two RLC entities are also configured to be mapped to different carriers, respectively.
Further, after the configuration is completed, further activation is required to enable the copy function to be used. The step of activating/deactivating (Activation/Deactivation) is realized by sending an Activation/Deactivation MAC Control Element (CE) through a network side, where the MAC CE includes a bit table (bitmap), each bit in the bitmap corresponds to an RB replicated configuration (RB replicated with replication), a bit indication corresponding to a certain RB replicated configuration is 1 to activate the RB, and a bit indication corresponding to a bit indication is 0 to deactivate the RB.
The RB may include a Data Radio Bearer (DRB) and a Signaling Radio Bearer (SRB).
In the activation step, after a certain RB duplication configuration is activated, the PDCP layer performs duplication on a Data packet, and sends two identical duplicated PDCP Protocol Data Units (PDUs) to two RLC entities corresponding to the RB, respectively, where the two RLC entities send the duplicated PDCP PDUs, respectively.
In the deactivation step, after a certain RB duplication configuration is deactivated, the corresponding restriction between the Logical Channel (LCH) corresponding to the RB duplication configuration and the carrier is cancelled; the PDCP layer at the transmitting end does not perform a copy operation on the new packet and transmits the new data to the Primary (Primary) RLC entity (i.e., the Primary LCH) without transmitting the new data to the Secondary (Secondary) RLC entity (i.e., the Secondary LCH); the sending PDCP entity informs the secondary RLC entity to cancel (cancel) the buffered data in the secondary LCH.
Referring to fig. 2, fig. 2 is a schematic diagram of an operation scenario of another data transmission method in the prior art, where the other data transmission method may be used in a PDCP copy function architecture in a Dual Connectivity (DC) scenario.
As shown in fig. 2, there are multiple sending end medium access layers and receiving end medium access layers, for example, the sending end medium access layers may include a first sending end medium access layer 231, a second sending end medium access layer 232, and the like; the receiver media access layers may include a first receiver media access layer 251, a second receiver media access layer 252, and so on.
In a specific implementation, each radio data link may be one of paths from the sending-end PDCP entity 110 to the receiving-end PDCP entity 170, for example, from the sending-end PDCP entity, the sending-end RLC entity, the sending-end medium access layer, a cell, the receiving-end medium access layer, the receiving-end RLC entity, to the receiving-end PDCP entity. The multiple sending end medium access layers and the sending end RLC entities have a corresponding relation, and the multiple receiving end medium access layers and the receiving end RLC entities have a corresponding relation.
In the PDCP copy function architecture in the existing DC scenario, a plurality of steps such as configuration, activation, and deactivation may also be included to implement the copy function.
In particular, the configuration steps may be the same as in the CA scenario.
Further, after the configuration is completed, further activation is required to enable the copy function to be used. The step of activating/deactivating (Activation/Deactivation) is realized by sending an Activation/Deactivation MAC Control Element (CE) through a network side, where the MAC CE includes a bit table (bitmap), each bit in the bitmap corresponds to an RB replicated configuration (RB replicated with replication), a bit indication corresponding to a certain RB replicated configuration is 1 to activate the RB, and a bit indication corresponding to a bit indication is 0 to deactivate the RB.
In the activation step, after a certain RB duplication configuration is activated, the PDCP layer performs duplication on a Data packet, and sends two identical duplicated PDCP Protocol Data Units (PDUs) to two RLC entities corresponding to the RB, respectively, where the two RLC entities send the duplicated PDCP PDUs, respectively.
In the deactivation step, after a certain RB duplication configuration is deactivated, the UE will fall back to the Split Operation (Split Operation) and adopt the related configuration of the original Split Operation.
However, in the prior art, a large signaling overhead is generated to achieve more flexible activation/deactivation control.
The inventor of the present invention finds, through research, that in the prior art, how many sending end logical channels to be used are used to send duplicated PDCP data packets, and which sending end logical channels to be used are used to perform data transmission, which is indicated for the UE by signaling at the network side, and two disadvantages exist:
1. the number of RBs with configurable copy functions and configurable wireless data links in each RB is large, so that the overhead of activated signaling is large;
2. the activation status of each wireless data link may be adjusted according to the transmission quality, which may result in too frequent transmission of the activation signaling.
That is, if the activation state of each leg is to be flexibly adjusted according to the channel transmission condition, there will be a large signaling overhead; to save signaling overhead, a more flexible activation/deactivation control is not achieved.
In the embodiment of the invention, the measured value of the transmission quality parameter of each wireless data link of each RB configured with the PDCP replication function is determined through testing; arranging the wireless data links of each RB according to the measured value of the transmission quality parameter of each wireless data link obtained through the test; selecting a preset number of wireless data links as standby wireless data links according to the arrangement sequence; and copying the PDCP entity at the UE side into the PDCP data packets with the preset number, and sending the PDCP data packets through the inactive wireless data link. By adopting the scheme, the wireless data links of each RB are arranged according to the measured value of the transmission quality parameter of each wireless data link obtained through testing, and then the wireless data links with the preset number are selected as the wireless data links to be used according to the arrangement sequence.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 3, fig. 3 is a flowchart of a method for a user terminal to upload data according to an embodiment of the present invention. The method for uploading data by the user terminal may include steps S31 to S34:
step S31: determining a measurement value of a transmission quality parameter of each radio data link of each RB configured with the PDCP replication function through testing;
step S32: arranging the wireless data links of each RB according to the measured value of the transmission quality parameter of each wireless data link obtained through the test;
step S33: selecting a preset number of wireless data links as standby wireless data links according to the arrangement sequence;
step S34: and copying the PDCP entity at the UE side into the PDCP data packets with the preset number, and sending the PDCP data packets through the inactive wireless data link.
In a specific implementation of step S31, the transmission quality parameter may be used to indicate the transmission quality of each radio data link of each RB for which the PDCP duplication function is configured.
In particular, the transmission quality parameter may comprise one or more of: the amount of data successfully transmitted per unit time and channel interference noise.
The transmission quality of the wireless data link can be determined according to the comparison result of the successfully transmitted data volume and the transmitted data volume.
The larger the amount of data successfully transmitted per unit time, the better the transmission quality parameter can be considered.
The channel interference noise generally includes detection of an interference signal frequency, and may include a technique of directly performing frequency measurement in a frequency domain, such as a frequency measurement algorithm using a search frequency window and an adjacent frequency window; techniques that do not measure frequency directly in the frequency domain, such as using correlation convolvers and fourier transform algorithms, may also be included.
The smaller the test value of the channel interference noise, the better the transmission quality parameter can be considered.
It should be noted that, in the embodiment of the present invention, there is no particular limitation on the data amount successfully transmitted in the unit time and the measurement manner of the channel interference noise.
In a specific implementation of step S32, the UE ranks the radio data links of each RB according to the measured value of the transmission quality parameter of each radio data link obtained through the test.
Specifically, the step of the UE ranking the radio data links of each RB according to the measured value of the transmission quality parameter of each radio data link obtained through the test may include: and according to the data quantity successfully transmitted in the unit time, performing descending order on the wireless data link of each RB.
It can be understood that, according to conventional settings and conventional practices, the wireless data links of each RB can be selected in a sequence from front to back, and since the larger the amount of data successfully transmitted in the unit time is, the better the transmission quality parameter can be regarded as being, the wireless data links of each RB are arranged in a descending order according to the amount of data successfully transmitted in the unit time, which helps a user terminal to select a wireless data link with better transmission quality for uplink data transmission according to the amount of data successfully transmitted in the unit time, which helps to improve the transmission quality and improve the utilization efficiency of transmission resources.
Specifically, the step of the UE ranking the radio data links of each RB according to the measured value of the transmission quality parameter of each radio data link obtained through the test may include: and according to the channel interference noise, performing ascending arrangement on the wireless data link of each RB.
It can be understood that, according to conventional settings and conventional practices, the radio data links of each RB can be selected in a sequence from front to back, and the smaller the test value of the channel interference noise is, the better the transmission quality parameter can be regarded as, so that the radio data links of each RB are arranged in a descending order according to the channel interference noise, which helps a user terminal to select a radio data link with better transmission quality for uplink data transmission according to the channel interference noise, helps to improve the transmission quality, and improves the utilization efficiency of transmission resources.
In another specific implementation manner of the embodiment of the present invention, the transmission quality parameters include a data amount successfully transmitted in a unit time and channel interference noise, and the step of ranking the radio data links of each RB according to the measured value of the transmission quality parameter of each radio data link obtained through the test may include: carrying out weighted average on the successfully transmitted data volume and the channel interference noise in the unit time of each wireless data link so as to determine the value of the transmission quality parameter of each wireless data link; and according to the value of the transmission quality parameter, performing descending or ascending arrangement on the wireless data link of each RB.
Specifically, when two or more transmission quality parameters need to be considered simultaneously, since the two parameters often have different units and cannot be directly added, the value of the transmission quality parameter of each wireless data link can be determined by a weighted average method with appropriate weight.
In another embodiment, the value of each transmission quality parameter may be normalized, and then the normalized values of the transmission quality parameters may be weighted and averaged to determine the value of the transmission quality parameter of each wireless data link.
In the embodiment of the present invention, when the transmission quality parameter includes a data amount and channel interference noise successfully transmitted in a unit time, the data amount and channel interference noise successfully transmitted in the unit time of each wireless data link are weighted and averaged to determine a value of the transmission quality parameter of each wireless data link, which is helpful for selecting an appropriate weight according to interference degrees of different transmission quality parameters on transmission quality, so that an obtained result can more accurately represent the transmission quality of different wireless data links.
It should be noted that, in the embodiment of the present invention, the influence of a value of a certain transmission quality parameter may also be improved by setting a weight, for example, when the influence of channel interference noise is emphasized more, the weight value corresponding to the channel interference noise may be increased, so that the arranged first wireless data links have smaller channel interference noise.
In a specific implementation of step S33, the UE selects a preset number of wireless data links as the inactive wireless data links in the ranked order.
In a specific implementation, before selecting the preset number of wireless data links as the inactive wireless data links, the method for the user terminal to upload data may further include: a preset number of inactive wireless data links per RB is received from the network side.
The preset data may be sent to the UE by a network side (e.g., a base station), and the preset parameter threshold may be subsequently changed through reconfiguration. For example, may be configured using RRC/MAC/PYH messages.
The preset number may also be predefined, e.g. specified by a protocol, and not modifiable.
Referring to fig. 4, fig. 4 is a schematic view of a working scenario of a method for uploading data by a user terminal in an embodiment of the present invention. The data transmission method can be used for a PDCP copy function architecture in a DC scenario.
As shown in fig. 4, the RB configured with the PDCP replication function has N radio data links.
Specifically, the UE PDCP entity 410 may upload PDCP data packets to the first UE RLC entity 421, the second UE RLC entity 422, and the N UE RLC entity 423 in … …, respectively, and upload the PDCP data packets to the first UE medium access layer 431 through the first UE logical channel corresponding to the first UE RLC entity 421, the second UE logical channel corresponding to the second UE RLC entity 422 to the second UE medium access layer 432, and the N UE logical channel corresponding to the N UE RLC entity 423 to the N UE medium access layer 433. Wherein N is a positive integer.
Further, the PDCP packets may be respectively uploaded through different cells, for example, the PDCP packets sent by the first UE logical channel are uploaded through the first cell 441, the PDCP packets sent by the second UE logical channel are uploaded through the second cell 442, and the PDCP packets sent by the nth UE logical channel are uploaded through the nth cell 443 in … ….
In the embodiment of the present invention, taking the preset number of 2 as an example for explanation, two wireless data links can be selected as the standby wireless data links from the N wireless data links according to the ranking order.
Further, in the embodiment of the present invention, the preset number, which may be set to different RB settings, is the same or different.
Specifically, it may be set that all radio data links configured by all RBs configuring the copy function use the same preset number. For example, the preset number is 2, and the UE has three RBs to configure the copy function, and each RB has a configured radio data link (including a logical channel) as shown in fig. 4, each RB can use only 2 radio data links.
Further, the preset number of radio data links used by different RBs may be set to be different. For example, if the UE has three RBs to configure the copy function, and each RB configures a radio data link (including a logical channel) as shown in fig. 4, the preset number of the first RB may be set to 2, the preset number of the second RB may be set to 3, and the preset number of the third RB may be set to 4, so that the first RB may use 2 radio data links, the second RB may use 3 radio data links, and the third RB may use 4 radio data links.
In the embodiment of the present invention, the preset number that can be set to different RB settings is the same or different, so that different numbers of wireless data links can be adopted according to different RB requirements, which is helpful to improve the flexibility of selection and further improve the utilization efficiency of transmission resources.
It should be noted that, in the CA scenario, the preset number that can also be set to be different RB settings is the same or different, and for the related specific implementation and beneficial effects, reference is made to the foregoing and the related description in the DC scenario, and details are not repeated herein.
With continued reference to fig. 3, in a specific implementation of step S34, the UE side PDCP entity copies the preset number of PDCP data packets and transmits the PDCP data packets via the dormant radio data link.
In one embodiment, the PDCP entity receives 1 packet from an upper layer and copies the packet at the PDCP entity. Specifically, the PDCP entity may copy the PDCP data packets N-1 times to obtain a total number of PDCP data packets N according to the number of inactive radio data links being N, and further send the N PDCP data packets through the inactive radio data links.
In the embodiment of the invention, the wireless data links of each RB are arranged according to the measured value of the transmission quality parameter of each wireless data link obtained through testing, and then the wireless data links with the preset number are selected as the wireless data links to be used according to the arrangement sequence.
Referring to fig. 5, fig. 5 is a schematic structural diagram of an apparatus for uploading data by a user terminal in an embodiment of the present invention. The apparatus for uploading data by the user terminal may include:
