Description

Uplink control information transmission method, device, system and storage medium

Technical field

The present invention relates to communication technologies, and more particularly to an uplink control information transmission method, apparatus, system, and storage medium.

Background technique

With the development of communication technologies, mobile multi-connection data transmission technology has also been developed, wherein the mobile multi-connection data transmission technology includes a technology in which a terminal and a plurality of base stations simultaneously establish and connect a wireless link.

FIG. 1 is a schematic structural diagram of an embodiment of a mobile multi-connection data transmission system in the prior art. As shown in FIG. 1, the user equipment (UE) is respectively connected to at least one first network side device and one second network side device, and the second network side device and the at least one first network side device are respectively directly or In the indirect connection, the UE performs multiple connection operations with the at least one first network side device and one second network side device. The first network side device may be a secondary base station, and the second network side device may be a primary base station. The UE and the primary base station may separately perform physical layer uplink control information (UCI) transmission on the first wireless connection; the UE and the secondary base station 1 may independently perform UCI transmission on the second wireless connection; And the secondary base station N can independently perform UCI transmission on the third wireless connection. For example, after receiving a signal sent by an unlicensed carrier, the UE first needs to perform a Listen Before Talk (LBT) operation, that is, a Clear Channel Assessment (CCA), when the channel is idle. Under certain conditions, an unlicensed carrier channel can be used for data transmission for a period of time. The UCI information on any one of the wireless connection links does not contain any UCI information related to other wireless connection links, and is not affected by the quality of other wireless connection links.

However, in the process of implementing the above prior art, the inventors of the present invention found that the UE receives The UE needs to send the UCI in the uplink subframe n+L in the preset uplink subframe n+L. The UE needs to perform the LBT or CCA first because the LBT is required on the unlicensed carrier. It is detected that when detecting that it is not idle, the UE cannot use the subframe n+L to transmit the UCI. As a result, the network measurement device cannot know the case of transmitting the data block in the downlink through the subframe n and the CSI monitoring information in the past period, thereby causing the downlink data transmission performance of the system to decrease.

FIG. 5 is a schematic structural diagram of a system for transmitting an uplink control information according to an embodiment of the present invention; the system structure applicable to this embodiment is as shown in FIG. 5, and a single Pcell serving cell macro coverage is performed on an authorized carrier of the LAA-MeNB, and is passed at a remote end. The X2 interface is connected to the LAA-SeNB base station, wherein the total delay of the X2 interface control information transmission and processing is estimated to be 2 ms, and the LAA-SeNB has a plurality of LAA Scells deployed on the unlicensed carrier for hotspot capacity enhancement. When the UE is in the common coverage of the Pcell+LAA Scells, the primary base station LAA-MeNB decides to configure the LAA-DC dual-connection operation for the UE to perform downlink data splitting of the user service, that is, the UE can simultaneously from the LAA MCG-link and the LAA SCG. -link two wireless connection links, downlink receiving data blocks. Both the LAA-MeNB and the LAA-SeNB base station and UE support the capabilities of the inventive method.

It should be noted that, in this embodiment, the first network side device is a LAA-SeNB, and the second network side device is a LAA-MeNB.

The uplink control information transmission method provided by the embodiment of the present invention includes:

Step 501: The terminal acquires a data block that is sent by the first network side device by using the first link.

Here, the first network side device LAA-SeNB successfully competes for a certain Transmission Burst resource through the LBT operation, and the LAA-SeNB schedules and transmits one data block in the downlink subframe N time position on the LAA Scells. Then, after successfully parsing the data block, the UE generates the UCI belonging to the LAA SCG-link at the default N+4 uplink subframe time position, and simultaneously performs the CSI measurement of the LAA SCG-link, and finally generates a corresponding complete. UCI. The complete UCI may include any one or a combination of the following: a first UCI, a second UCI, and a third UCI. The UCI carries any one of the following or a combination thereof: physical layer uplink control information, channel state information, and uplink control information of a protocol layer.

It should be noted that, before or after the step 501, the LAA-MeNB performs LAA-DC dual connectivity operation on the RRC message RRC Connection Reconfiguration, and performs downlink transmission of the downlink data block on the LAA-SCG side. Further, the acquisition is The configuration information, that is, the LAA-MeNB enables and configures the LAA-SeNB and the UE to uplink and transmit its associated UCI uplink control information through the PUCCH channel on the primary base station Pcell.

Step 502: The UE sends the UCI information to the LAA-MeNB in the uplink according to the configured information on the PUCCH channel N+4 subframe time position on the Pcell.

Here, the UCI information of this embodiment includes both the UCI complete information of the LAA SCG-link and the UCI complete information of the LAA MCG-link, and contains respective identifiers for distinguishing UCI ownership, such as link id.

Step 503: The LAA-MeNB parses the received joint UCI information, and confirms that the first UCI, that is, the UCI information corresponding to the downlink data transmission of the LAA Scells, is included.

In an embodiment, the part of the UCI information may be extracted and transmitted to the LAA-SeNB through the X2 interface bearer. Since the LAA-SeNB has been previously enabled and configured by the LAA-MeNB, the LAA-SeNB does not need to monitor the UCI uplink assisted transmission of the UE on the LAA SCG-link for the UE, and only needs to monitor the UCI transmission from the LAA-MeNB side. . Since the LAA-SeNB knows in advance that the total delay of the X2 interface control information transmission and processing is 2 ms, the LAA-SeNB will be in the "virtual" time position of the N+6 uplink subframe (Long Term Evolution (LTE) subframe). The length of 1 ms) receives the data block UCI uplink control information corresponding to the location scheduling transmission of the downlink subframe N time.

Step 504: The LAA-SeNB successfully receives the UCI information from the LAA-MeNB side at the "virtual" time position of the uplink subframe of N+6.

In practical applications, it can be inferred that it corresponds to the data block that was previously sent in the downlink subframe N time on the LAA Scells, and knows its air interface transmission result and the CSI condition and other downlink transmission block transmission in the past observation period. Happening.

It should be noted that, as the LAA-SeNB continuously transmits data blocks on the LAA Scells, the foregoing process is repeated, and the UE does not need to perform uplink LBT operation and UCI uplink auxiliary transmission on the LAA Scells, that is, the pair is reduced. Unauthorized carrier resource competition, and always passed The PUCCH channel of the Pcell is used in conjunction with the uplink transmission assist UCI.

Step 505: The LAA-MeNB sends the configuration de-enable information through the radio resource control RRC message.

In this embodiment, the RRC message includes an RRC Connection Reconfiguration message, and the LAA-MeNB sends the configuration de-enable information through the Radio Resource Control (RRC) message to disable and configure the LAA-SeNB and the UE through the primary base station. The PUCCH channel on the Pcell uplink transmits its associated UCI uplink control information. Afterwards, the UE independently uploads its own UCI uplink control information through the LAA SCG-link, so that the UE needs to perform uplink LBT operation and UCI uplink auxiliary transmission attempt on the LAA Scells.

FIG. 6 is a schematic structural diagram of an uplink control information transmission system according to an embodiment of the present invention; the system structure applicable to this embodiment is as shown in FIG. 6 , and is aggregated in an LWA, ie, LTE and Wireless Local Area Networks (WLAN) wireless access nodes. In the scenario, there is a macro coverage of a single Pcell serving cell on the authorized carrier of the LWA-MeNB, and a WLAN LWA-WT base station is connected through the Xw interface at the remote end, wherein the total delay of the Xw interface control information transmission and processing is estimated to be 1ms, the LWA-WT has a WLAN AP deployment on the unlicensed carrier for hotspot capacity enhancement. When the UE is in the common coverage of the Pcell+WLAN AP, the primary base station LWA-MeNB decides to configure the LWA dual-connection operation for the UE to perform downlink data splitting of the user service, that is, the UE can simultaneously obtain two LTE-links and LWA WLAN-links from the LWA. On the wireless connection link, the downlink receives the data block and aggregates the reordering merge. Both the LWA-MeNB and the LWA-WT base station and UE support the content capabilities of the present invention.

It should be noted that, in this embodiment, the first network side device is an LWA-WT, and the second network side device is an LAA-MeNB.

Step 601: The LWA-MeNB performs an LWA dual-connection operation to the UE through the RRC message RRC Connection Reconfiguration, and performs offloading of the downlink data block on the LWA-WT WLAN wireless connection link side. Further LWA-MeNB enable and configure LWA-WT And the UE uplinks its associated UCI uplink control information through the PUCCH channel on the primary base station Pcell. According to the timing characteristics of the WLAN side downlink transmission and the UCI uplink auxiliary transmission, the LWA-MeNB defaults to: corresponding to the downlink data block (WLAN MAC PDU) received at the N-time position of the WLAN air interface, the UE needs the PUCCH channel N+ on the Pcell. 1 The uplink subframe time position transmits the corresponding UCI.

Step 602: The WLAN AP on the LWA-WT side successfully contends to a certain Transmission Burst resource through the LBT operation, and sends one data block at the N-th time of the WLAN air interface. After successfully parsing the data block, the UE generates complete UCI information (including ACK/NACK and other WLAN MAC PDU protocol headers) in the default N+1 uplink subframe time position. And other high-level control protocol package information).

Step 603: The UE sends the combined UCI information to the LWA-MeNB in the uplink of the PUCCH channel N+1 subframe time position on the Pcell according to the LWA-MeNB enable and configuration. The UCI information here includes both the complete UCI information of the WLAN wireless connection link side and the UCI complete information of the LWA LTE-link side, and contains respective identifiers for distinguishing UCI ownership, such as link id.

Step 604: The LWA-MeNB parses the received joint UCI information, and confirms that the complete UCI related information related to the WLAN wireless connection link side is included, so that the part of the UCI information is further extracted and transmitted to the LWA through the Xw interface bearer. WT. Since the LWA-WT has been previously enabled and configured by the LWA-MeNB, the LWA-WT does not need to monitor the UCI uplink assisted transmission of the UE on the WLAN wireless connection link for the UE, and only needs to monitor the UCI from the LWA-MeNB side. transfer. Since the LWA-WT knows in advance that the total delay of the Xw interface control information transmission and processing is 1 ms, the LWA-WT will receive the corresponding position in the "virtual" time position of the N+2 uplink subframe (the length of the LTE subframe is 1 ms). The data block UCI uplink control information transmitted at the N time position of the downlink subframe.

Step 605: The LWA-WT successfully succeeds from the "virtual" time position of the uplink subframe of N+2. The LWA-MeNB side receives the UCI information, so as to derive that it corresponds to the data block sent downstream in the downlink subframe N time on the WLAN air interface, and knows its air interface transmission result and the CSI situation and other downlinks in the past observation period. Packet transmission situation.

Step 606: As the LWA-WT continuously transmits data blocks on the WLAN air interface, the foregoing process is repeated, and the UE does not need to perform uplink LBT operation and UCI uplink auxiliary transmission attempt on the WLAN wireless connection link (reduce the unlicensed carrier). The competition of resources), and the uplink auxiliary UCI is jointly transmitted through the PUCCH channel of the Pcell.

Step 607: At a certain moment, the LWA-MeNB disables and configures the LWA-WT and the UE to uplink and transmit the related UCI uplink control information through the PUCCH channel on the primary base station Pcell through the RRC message RRC Connection Reconfiguration. Then, the UE independently uploads its own UCI uplink control information through the WLAN wireless connection link, so that the UE needs to perform uplink LBT operation and UCI uplink transmission attempt on the WLAN air interface.

FIG. 7 is a schematic structural diagram of an uplink control information transmission system according to an embodiment of the present invention; as shown in FIG. 7 , in the scenario of authorizing DC+LWA technology, there is a single Pcell serving cell on an authorized carrier of the MeNB. The macro coverage is connected to the SeNB through the X2 interface and the SeNB base station. The total delay of the X2 interface control information transmission and processing is estimated to be 1 ms. The SeNB has a PScell and several Scells deployed on the authorized carrier. Capacity enhancement; at the same time, the remote MeNB also connects to the WLAN LWA-WT base station through the Xw interface, and the total delay of the Xw interface control information transmission and processing is estimated to be 4 ms, and the LWA-WT has a WLAN AP deployment on the unlicensed carrier. Configured as hotspot capacity enhancement. When the UE is in the common coverage of the Pcell+PScell+Scells+WLAN AP, the primary base station MeNB decides to configure the DC+LWA three-connection operation for the UE to perform downlink downlink data for the user service, that is, the UE can simultaneously access the MCG-link and the SCG. -link and WLAN-Link three wireless connection links uplink and downlink receive data blocks. Both the MeNB and the SeNB base station and the LWA-WT base station and the UE support the content capabilities of the present invention. The uplink load or interference on the Pcell serving cell on the MCG side is heavy at this time, and The uplink load of the PScell on the SCG side is lighter, and the unlicensed carrier frequency of the WLAN AP is also less competitive and the Xw delay is larger. Therefore, the MeNB determines to enable and configure the UCI joint uplink auxiliary transmission mode of the present invention. The PUCCH channel on the PScell on the SCG side is responsible for the UCI joint uplink transmission related to the MCG/SCG serving cell, and the WLAN wireless connection link still independently transmits the UCI to which the UE belongs. The detailed implementation steps of the present invention are as follows:

It should be noted that, in this embodiment, the first network side device is an SeNB, the second network side device is an MeNB, and the third network side device is an LWA-WT.

Step 701: The MeNB performs a three-connection operation of the DC+LWA to the UE through the RRC message RRC Connection Reconfiguration, and simultaneously performs offload transmission of the downlink data block on the SeNB/SCG side and the LWA-WT side. Further, the MeNB enables and configures the SeNB and the UE to uplink and transmit the related UCI uplink control information through the PUCCH channel on the PScell of the secondary base station SeNB. The MeNB is configured to the UE: corresponding to the downlink data block received at the time of the downlink subframe N time on the Pcell, the UE needs to send the corresponding UCI at the PUCCH channel N+3 uplink subframe time position on the PScell.

Step 702: The MeNB schedules and transmits one data block in the downlink subframe N time position on the Pcell. After successfully parsing the data block, the UE generates the UCI information belonging to the MCG-link at the newly configured N+3 uplink subframe time position, and simultaneously performs the CSI measurement of the MCG-link, and finally generates the complete corresponding to the MCG side. UCI information.

Step 703: The UE sends the combined UCI information to the SeNB in the uplink of the PUCCH channel N+3 subframe time position on the SCG side PScell according to the MeNB enable and configuration. The UCI information here combines both the UCI complete information on the SCG-link side and the UCI complete information of the MCG-link, and contains its own identifier to distinguish the UCI belonging, such as the link id.

Step 704: The SeNB parses the received joint UCI information, and confirms that the UCI information corresponding to the downlink data transmission of the MCG side Pcell is included, so that the part of the UCI information is further extracted and transmitted to the MeNB through the X2 interface bearer. Since the SeNB has been previously MeNB The UeNB does not need to monitor the UCI uplink transmission of the UE on the MCG-link for the UE, and only needs to monitor the UCI transmission from the SeNB side. Since the MeNB knows in advance that the total delay of the X2 interface control information transmission and processing is 1 ms, the MeNB will receive the corresponding downlink subframe N in the "virtual" time position of the N+4 uplink subframe (the LTE subframe length is 1 ms). The time block is scheduled to transmit the UCI uplink control information and other downlink data block transmission conditions.

Step 705: The MeNB successfully receives the UCI information from the SeNB side in the "virtual" time position of the uplink subframe of the N+4, and deduces that it corresponds to the data block scheduled to be downlinked in the downlink subframe N time on the Pcell. And know its air interface transmission results and CSI conditions in the past observation period.

Step 706: As the MeNB continuously sends downlink data blocks on the Pcell, the foregoing process is repeated, and the UE does not need to perform UCI uplink auxiliary transmission attempt on the Pcell (reducing Pcell uplink load and interference), and always passes the PScell on the SCG side. The PUCCH channel is used in conjunction with the uplink transmission UCI. At the same time, the downlink data transmission on the WLAN Link side and the corresponding UCI uplink assistance are performed independently in the local link, and it does not matter with the MCG Link/SCG Link.

Step 707: At a certain moment, the MeNB commands the UE to enable the previous joint uplink auxiliary transmission mode by using the air interface MAC-CE message, and then the UE separately uploads its own UCI uplink assistance through the MCG-link and the SCG-link, so that the UE needs to be in the UE. The PGC on the MCG side attempts to make UCI uplink assisted transmission according to the traditional timing relationship of N+4. The UCI uplink auxiliary content received by the SeNB does not include the content belonging to the MCG side, so there is no need to transmit the relevant UCI content to the MeNB.

8 is a schematic structural diagram of an uplink control information transmission system according to an embodiment of the present invention; as shown in FIG. 8 , an operator jointly deploys and utilizes an authorized DC+LWA technology, and has an authorized carrier on the MeNB. A single Pcell serving cell macro coverage, connecting the SeNB base station through the X2 interface at the remote end, and estimating the total delay of the X2 interface control information transmission and processing is 1 ms. The SeNB has a PScell and a number of Scells deployed on the authorized carrier, and is configured to increase the hotspot capacity. At the same time, the remote MeNB also connects to the WLAN LWA-WT base station through the Xw interface to estimate the total delay of the Xw interface control information transmission and processing. 8ms, the LWA-WT has two WLAN APs deployed on the unlicensed carrier, configured with hotspot capacity enhancement. When the UE is in the common coverage of the Pcell+PScell+Scells+WLAN AP1+AP2, the primary base station MeNB decides to configure the DC+LWA four-connection operation for the UE to perform downlink traffic splitting of the user service, that is, the UE can simultaneously access the MCG-link. It receives uplink and downlink data blocks with four wireless connection links of SCG-link and WLAN-Link1+WLAN-Link2. Both the MeNB and the SeNB base station and the LWA-WT base station and the UE support the content capabilities of the present invention. The uplink load and interference on the SCcell serving cell on the SCG side are heavy, and the uplink load of the Pcell on the MCG side is lighter, and the unlicensed carrier frequency of the WLAN APs is less competitive and the Xw delay is larger. Therefore, the MeNB determines to enable and configure the UCI joint uplink auxiliary transmission mode of the present invention, so that the PUCCH channel on the Pcell of the MCG side bears the UCI joint uplink control information related to the MCG/SCG serving cell, and the WLAN wireless connection link still uplinks independently. The auxiliary implementation of the UCI to which the user belongs is as follows:

Step 801: The MeNB performs four-connection operation of the DC+LWA to the UE through the RRC message RRC Connection Reconfiguration, and simultaneously performs offload transmission of the downlink data block on the SeNB/SCG side and the LWA-WT side. Further, the MeNB enables and configures the SeNB and the UE to uplink and transmit the associated UCI uplink control information through the PUCCH channel on the Pcell of the primary base station MeNB. The MeNB is configured to the UE: corresponding to the downlink data block received at the time of the downlink subframe N time on the SCG side PScell or the Scells, the UE needs to send the corresponding UCI on the PUCCH channel N+3 uplink subframe time position on the Pcell.

Step 802: The SeNB sends a number of positions in the downlink subframe N time position on the PScell. According to the block. After successfully parsing the data block, the UE generates the UCI information belonging to the SCG-link at the newly configured N+3 uplink subframe time position, and simultaneously performs the CSI measurement of the SCG-link, and finally generates the complete corresponding to the SCG side. UCI information.

Step 803: The UE sends the combined UCI information to the MeNB in the uplink of the PUCCH channel N+3 subframe time position on the MCG side Pcell according to the MeNB enable and configuration. The UCI information here combines both the UCI complete information on the SCG-link side and the UCI complete information of the MCG-link, and contains its own identifier to distinguish the UCI belonging, such as the link id.

Step 804: The MeNB parses the received joint UCI information, and confirms that the UCI information corresponding to the downlink data transmission of the SCG side PScell is included, so that the part of the UCI information is further extracted and transmitted to the SeNB through the X2 interface bearer. Since the SeNB has been previously enabled and configured by the MeNB, the SeNB does not need to monitor the UCI uplink assisted transmission of the UE on the SCG-link for the UE, and only needs to monitor the UCI transmission from the MeNB side. Since the SeNB knows in advance that the total delay of the X2 interface control information transmission and processing is 1 ms, the SeNB will receive the corresponding downlink subframe N in the "virtual" time position of the N+4 uplink subframe (the LTE subframe length is 1 ms). The time position is scheduled to transmit the data block UCI uplink control information.

Step 805: The SeNB successfully receives the UCI information from the MeNB side in the "virtual" time position of the uplink subframe of the N+4, and deduces that it corresponds to the data block scheduled to be downlinked in the downlink subframe N time on the PScell. And know its air interface transmission results and CSI conditions and other downlink data block transmissions in the past observation period.

Step 806: As the SeNB continuously sends downlink data blocks on the PScell, the foregoing process is repeated, and the UE does not need to perform UCI uplink auxiliary transmission attempt on the PScell (reducing PScell uplink load and interference), and always passes the Pcell on the MCG side. The PUCCH channel is used in conjunction with the uplink transmission UCI. At the same time, the two downlink data transmissions on the WLAN Links side and the corresponding UCI uplink assistance are performed independently in the local link, and it does not matter with the MCG Link/SCG Link.

Step 807: At some time, the MeNB commands the UE to be enabled by using the air interface PDCCH message. The joint uplink assisted transmission mode, after which the UE independently uploads its own UCI uplink control information through MCG-link and SCG-link, so that the UE needs to perform UCI uplink auxiliary transmission according to the traditional timing relationship of N+4 on the PScell on the SCG side. try. The UCI uplink auxiliary content received by the MeNB does not include the content belonging to the SCG side, so there is no need to transmit the relevant UCI content to the SeNB.
