Description

Uplink transmission method based on carrier aggregation, storage medium and user equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to an uplink transmission method based on carrier aggregation, a storage medium, and a user equipment.

Background

The fifth generation mobile Communication system (5G NR) includes three major application scenarios, namely enhanced mobile Broadband (eMBB), Massive Machine Type Communication (mtc), and low-latency high-reliability Communication (URLLC). The scenes put forward the requirements of high reliability, low time delay, large bandwidth, wide coverage and the like for the system.

A User Equipment (UE) may support different types of traffic simultaneously, for example, a drone in a smart factory needs to support eMBB traffic (e.g., surveillance video) and URLLC traffic (e.g., motion control) simultaneously, resulting in uplink transmission collisions inside the UE, i.e., there is an overlap of radio resources between uplink information with different Quality of Service (QoS) requirements.

Uplink transmission collision inside the UE is the focus of research on 3GPP Release 16 and Release 17, and some solutions have been proposed for various scenarios. However, if the UE supports uplink Carrier Aggregation (CA), these solutions are not sufficient to solve the uplink transmission collision problem in the Carrier Aggregation scenario, and cannot ensure the reliability of communication.

In the description of the present application, "a plurality" means two or more unless specifically limited otherwise. In addition, the terms "first" and "second" are used to distinguish a plurality of elements from each other. For example, a first constraint may also be referred to as a second constraint, and similarly, a second constraint may also be referred to as a first constraint, without departing from the scope of the present application. The first constraint and the second constraint are both constraints, but they are not the same constraint.

As shown in fig. 1, fig. 1 is a schematic configuration diagram of a communication system. The communication system comprises a base station 1 and user equipment 2, wherein the base station 1 may comprise various macro base stations, micro base stations, relay stations, access points and the like, and the user equipment 2 may be various handheld devices, vehicle-mounted devices, wearable devices and other electronic devices with wireless communication functions. The base station 1 and the user equipment 2 may be connected through an air interface technology (such as NR UU).

The user equipment 2 may support carrier aggregation, which refers to a technique of aggregating multiple Component Carriers (CCs) together to support a larger transmission bandwidth. Different user equipments may be configured with different CCs, each CC may correspond to an independent Serving Cell (Serving Cell), for example, a primary CC corresponds to a primary Cell (PCell), a Secondary CC corresponds to a Secondary Cell (SCell), and the user equipment 2 supporting carrier aggregation may be connected to one PCell and multiple scells.

The ue 2 sends information to the base station 1 through a Physical Uplink Channel, where the Physical Uplink Channel includes a Physical Uplink Shared Channel (PUSCH) and a Physical Uplink Control Channel (PUCCH). The PUCCH may be used to transmit Uplink Control Information (UCI), which may include at least one of Channel State Information (CSI), hybrid automatic repeat request (HARQ), and Uplink Scheduling Request (SR). The PUSCH may be used to transmit uplink data information and may also be used to transmit UCI.

As shown in fig. 2, fig. 2 is a flowchart illustrating an uplink transmission method based on carrier aggregation according to an embodiment of the present application, where the uplink transmission method is applied to a user equipment, and the user equipment may be the user equipment 2 in fig. 1. The specific flow of the uplink transmission method may include steps 101 to 103:

101. when the transmission of a plurality of uplink messages has conflict, determining the conflict type of the plurality of uplink messages.

In the embodiment of the present application, the uplink information refers to information transmitted by the user equipment to the base station, and the uplink information has multiple information types, for example, PUCCH information, PUSCH information, and the like. The PUCCH information refers to information transmitted through the PUCCH, such as uplink control information UCI; the PUSCH information refers to information transmitted through the PUSCH, such as uplink data information. Different uplink information may be transmitted on different cells (i.e., different CCs) or may be transmitted on the same cell (i.e., the same CC).

The collision of the transmission of the plurality of uplink information means that the transmission resources of the plurality of uplink information overlap. According to the condition of the cell transmitting the plurality of uplink information, the collision type of the plurality of uplink information can be determined. The cell condition refers to whether multiple uplink information is transmitted in the same cell or different cells.

Specifically, as shown in fig. 3, when there is a collision in the transmission of multiple pieces of uplink information in step 101, determining the collision type of the multiple pieces of uplink information may include steps 201 to 203:

201. when the transmission of a plurality of uplink information has conflict, if the plurality of uplink information are transmitted in the same cell, determining that the conflict type is intra-cell conflict.

201. When the transmission of a plurality of uplink information has conflict, if the plurality of uplink information is transmitted in different cells, determining that the conflict type is inter-cell conflict.

203. When the transmission of a plurality of uplink information has conflict, if the plurality of uplink information is transmitted in a plurality of cells and a plurality of uplink information is transmitted in each cell, determining that the conflict type comprises intra-cell conflict and inter-cell conflict.

It should be noted that, the transmission collisions of multiple uplink information may be divided into three types, that is, there are only intra-cell collisions, only inter-cell collisions, and both intra-cell collisions and inter-cell collisions.

102. And processing the plurality of uplink information by adopting a corresponding transmission processing mode according to the conflict type.

In the embodiment of the application, different transmission processing modes are adopted for processing aiming at different conflict types so as to solve different uplink transmission conflict problems.

If the conflict type is intra-cell conflict, that is, conflicting uplink information does not exist between different cells, the uplink information in the same cell is processed by adopting a first transmission processing mode, so that the intra-cell uplink transmission conflict problem can be solved. If the conflict type is inter-cell conflict, that is, there is no conflicting uplink information in the same cell, the uplink information in different cells is processed by adopting a second transmission processing mode, so that the problem of inter-cell uplink transmission conflict can be solved. If the conflict type includes intra-cell conflict and inter-cell conflict, that is, multiple uplink information of conflict includes both uplink information transmitted in the same cell and uplink information transmitted in different cells, a first transmission processing mode is first adopted to process the uplink information of conflict in the same cell, that is, each cell first solves the problem of uplink transmission conflict inside each cell, so that no uplink information of conflict exists in the same cell after processing, and then a second transmission processing mode is adopted to process the uplink information of conflict between different cells, so as to solve uplink transmission conflict between different cells, thereby solving all uplink transmission conflict problems.

And when the conflict in the cell is solved, processing by adopting a first transmission processing mode. Specifically, as shown in fig. 4, the processing the plurality of uplink information by using the corresponding transmission processing manner according to the collision type in step 102 includes steps 301 to 304:

301. and when the conflict type is intra-cell conflict, determining the information types of a plurality of uplink information in the same cell.

Since the information type of the uplink information includes PUCCH information and PUSCH information, a plurality of uplink information in the same cell may have a plurality of types of collisions, which can be roughly classified into three types, that is, collision of PUCCH information and PUSCH information, collision of a plurality of PUSCH information, and collision of a plurality of PUCCH information. And according to different information types of the plurality of uplink information in the same cell, performing different processing on the plurality of uplink information in the same cell.

If the uplink information in the same cell includes the first PUCCH information and the first PUSCH information, step 302 is executed; if the uplink information in the same cell includes PUSCH information, step 303 is executed; if the plurality of uplink information in the same cell includes a plurality of PUCCH information, step 304 is performed.

302. Detecting whether the first PUCCH information and the first PUSCH information meet multiplexing conditions; if so, multiplexing the first PUCCH information and the first PUSCH information; and if not, processing the first PUCCH information and the first PUSCH information according to a priority strategy.

The priority policy refers to comparing priorities of a plurality of uplink messages and processing the uplink messages according to the priorities. The PUCCH Information (UCI) and PUSCH Information support two-level priority configuration, i.e., high priority and low priority, in the physical layer, and the priority is configured by Downlink Control Information (DCI) or Radio Resource Control (RRC) parameters. In order to ensure the transmission quality of the uplink information with high priority, the priority policy may be set to discard the uplink information with low priority and retain the uplink information with high priority, and if the priorities of multiple uplink information are the same, a policy of multiplexing NR release15 is adopted, or a policy of multiplexing NR subsequent versions is also adopted, which is not specifically limited herein.

For example, as shown in fig. 5, the uplink information collided in the PCell includes UCI1 and PUSCH1, where UCI1 is PUCCH information and PUSCH1 is PUSCH information. Detecting whether UCI1 and PUSCH1 meet multiplexing conditions, if so, multiplexing UCI1 and PUSCH1 and then transmitting the multiplexed UCI and PUSCH1 in the PCell, if not, adopting a priority strategy, selecting UCI1 with high priority from UCI1 and PUSCH1 and keeping the UCI1 in the PCell for transmission, and discarding PUSCH1 with low priority to solve transmission conflict between UCI1 and PUSCH 1. When UCI1 and PUSCH1 in the same cell collide, transmission after multiplexing of UCI1 and PUSCH1 is considered preferentially, so that the communication quality of high-priority transmission service is guaranteed, and meanwhile, the communication quality of low-priority transmission service is also guaranteed to a certain extent.

303. Detecting whether other cells have idle target transmission resources, wherein the time domain resources of the target transmission resources are the same as the time domain resources occupied by second PUSCH information, and the second PUSCH information is PUSCH information with low priority in the plurality of PUSCH information; if yes, allocating the target transmission resource to the second PUSCH information; and if not, discarding the second PUSCH information.

If a plurality of PUSCH information in the same cell collide with each other, the PUSCH information cannot be multiplexed, so that the PUSCH information with high priority is transmitted in the cell, and the PUSCH information with low priority is considered to be transmitted in other idle cells which do not transmit data.

For example, as shown in fig. 6, the uplink information collided in SCell1 includes PUSCH2 and PUSCH3, PUSCH2 and PUSCH3 are both PUSCH information, and PUSCH2 has high priority and PUSCH3 has low priority. If the PUSCH2 and the PUSCH3 are directly processed according to the priority policy, the transmission efficiency and the QoS requirement of the PUSCH may be reduced, so it is first detected whether other cells have idle target transmission resources, and when it is detected that the SCell2 is in an idle state at this time, that is, when the position of the SCell2 corresponding to the PUSCH3 in the SCell1 is in an idle state, the target transmission resource of the SCell2 is allocated to the PUSCH3, so that the PUSCH3 is transmitted in the SCell2, and the PUSCH2 is transmitted in the SCell1, so as to solve the problem of transmission collision between the PUSCH2 and the PUSCH3, and ensure simultaneous transmission of multiple paths of data while ensuring high priority transmission quality, and reduce the frequency of data discarding. The detection of whether SCell2 can transmit PUSCH3 is decided by the user equipment implementation inside, and is not required here.

For example, as shown in fig. 5, detecting that no other cell has an idle target transmission resource, according to the priority policy, the PUSCH3 is dropped and PUSCH2 is reserved for transmission in SCell1, so as to solve the problem of transmission collision between PUSCH2 and PUSCH 3.

304. Detecting whether second PUCCH information meets multiplexing conditions with first target PUSCH information transmitted in other cells, wherein the second PUCCH information is low-priority PUCCH information in the plurality of PUCCH information; if so, multiplexing the second PUCCH information and the first PUSCH information; and if not, discarding the second PUCCH information.

When a plurality of PUCCH information conflicts in the same cell, the PUCCH information with high priority is processed first, the PUCCH information with high priority is reserved in the cell to be transmitted, and then the PUCCH information with low priority is processed, and the PUCCH information with low priority is considered to be multiplexed with PUSCH information in other cells to be transmitted.

If the priorities of the plurality of PUCCH information configurations are the same, since the PUCCH information has a plurality of types, the priority order of the PUCCH information of different types may be set according to the type order of the high-level configuration, and the plurality of PUCCH information may be processed in sequence according to the priority order, for example, the priority order is aperiodic CSI, periodic/semi-static CSI, HARQ, SR, that is, aperiodic CSI is processed first, and SR is processed last, or the priority processing mechanism of NR release15 or a subsequent version may be multiplexed to perform priority processing on the PUCCH information of the same priority.

When detecting whether the low-priority PUCCH information and PUSCH information in other cells meet multiplexing conditions, detecting from small to large according to the cell sequence number, namely, detecting whether the other cells with the minimum cell sequence number have the PUSCH information which can be multiplexed or not, if so, multiplexing the low-priority PUCCH information and the PUSCH information in the cell and then transmitting the multiplexed information in the cell, otherwise, continuously detecting the other cells with the second-small cell sequence number, and if all other cells have no PUSCH information which can be multiplexed, discarding the low-priority PUCCH information.

For example, as shown in fig. 7, the multiple uplink information collided in the PCell includes UCI1 and UCI2, UCI1 and UCI2 are both PUCCH information, and UCI1 has a high priority and UCI2 has a low priority. The method comprises the steps of reserving UCI1 in a PCell for transmission, detecting whether a PUSCH1 between UCI2 and an SCell1 meets a multiplexing condition, if so, multiplexing the UCI2 and the PUSCH1 and then transmitting the multiplexed UCI1 and the multiplexed UCI 3583 in the SCell1, if not, continuously detecting whether a PUSCH2 between UCI2 and the SCell2 meets the multiplexing condition, if so, multiplexing the UCI2 and the PUSCH2 and then transmitting the multiplexed UCI2, and if not, discarding the UCI 2.

The uplink information with low priority is directly discarded, so that the stability of signaling and data transmission with high priority is mainly ensured, but the influence on the uplink information with low priority is large, if the current conflict is frequent, or certain uplink information with low priority has large data volume, the frequent discarding can have large influence on QoS, therefore, a cross-CC multiplexing method is preferably considered, so that the transmission quality of high priority is ensured, a plurality of uplink information is ensured to be transmitted simultaneously, and the frequency of data discarding is reduced.

In addition, if the uplink information collided in the same cell comprises a plurality of PUCCH information and a plurality of PUSCH information, the method in step 303 may be adopted to process the PUSCH information in the cell, so that the cell only retains one high-priority PUSCH information, the low-priority PUSCH information may be dropped or transmitted through other idle cells, then, the method in step 304 is used to process a plurality of PUCCH information, so that the cell only retains one high priority PUSCH information, the low priority PUCCH information can be discarded or multiplexed with the PUSCH information in other cells and transmitted in other cells, at this time, the cell only has one PUSCH information and one PUCCH information, the method in step 302 is continuously used to multiplex the retained PUCCH information with the PUSCH information and transmit in the cell, or processing the reserved PUCCH information and PUSCH information by adopting a priority strategy so as to solve the problem of various uplink transmission conflicts.

And when the inter-cell conflict is solved, processing by adopting a second transmission processing mode. Specifically, as shown in fig. 8, the processing the uplink information in step 102 by using the corresponding transmission processing manner according to the collision type includes steps 401 to 406:

401. and when the conflict type is inter-cell conflict, determining the information type of the uplink information in different cells and the transmission indication information of the user equipment.

Since the information type of the uplink information includes PUCCH information and PUSCH information, uplink information in different cells may have various types of combinations. However, since the user equipment supports carrier aggregation, PUCCH information (UCI) of all CCs can only be transmitted on one uplink CC, which also means that data transmitted by multiple downlink CCs may need to be acknowledged (acknowledged) in the same uplink CC, so the collision of uplink information in different cells can be roughly divided into two types, namely, collision of PUCCH information and PUSCH information and collision of multiple PUSCH information.

The transmission indication information of the user equipment may be used to indicate whether the user equipment supports simultaneous transmission of PUCCH information and PUSCH information, and whether simultaneous transmission of multiple PUSCH information is supported. It should be noted that the user equipment supporting carrier aggregation supports simultaneous transmission of multiple PUSCH information by default. The simultaneous transmission of the PUCCH information and the PUSCH information requires that the user equipment has or starts the related function, if the user equipment does not start the simultaneous transmission of the PUCCH and the PUSCH function or the user equipment does not have the capability, the transmission indication information indicates that the simultaneous transmission of the PUCCH information and the PUSCH information is not supported; if the user equipment starts the function of simultaneously transmitting the PUCCH and the PUSCH, the transmission indication information supports the simultaneous transmission of the PUCCH information and the PUSCH information.

And carrying out different processing on the uplink information in different cells according to the information types of the uplink information in different cells and the transmission indication information of the user equipment.

If the uplink information in different cells includes multiple pieces of PUSCH information, and the user equipment supports simultaneous transmission of the multiple pieces of PUSCH information by default, transmission of the multiple pieces of PUSCH information in respective cells is reserved, and mutual transmission is not affected.

As shown in fig. 9, PUSCH information in different cells includes PUSCH1 transmitted in Scell1 and PUSCH2 transmitted in Scell2, while PUSCH1 and PUSCH2 are transmitted, i.e., PUSCH1 is still transmitted through Scell1 and PUSCH2 is still transmitted through Scell2, without affecting each other's transmission.

If the uplink information in different cells includes the third PUCCH information transmitted in the first cell and the third PUSCH information transmitted in the second cell, step 402 is performed.

402. And detecting whether the transmission indication information supports simultaneous transmission of PUCCH information and PUSCH information, if so, executing step 403, and if not, executing step 404.

When the PUCCH information and PUSCH information in different cells collide, the transmission indication information is different, and the processing manner is different. It should be noted that, if the transmission indication information does not support simultaneous transmission of PUCCH information and PUSCH information, for a user equipment supporting carrier aggregation, the PUCCH information may be transmitted only on PCell, and there is no requirement for PUSCH information, that is, the PUSCH information may be transmitted on both PCell and SCell, that is, only PUSCH information may be transmitted on SCell; if the transmission indication information is to support simultaneous transmission of PUCCH information and PUSCH information, for a user equipment supporting carrier aggregation, the PUCCH information may be transmitted on only one uplink CC, and in this embodiment, it is assumed that the PUCCH information may be transmitted on only a PCell, and the PUSCH information may be transmitted on both the PCell and the SCell, that is, only PUSCH information may be transmitted on the SCell.

403. Reserving transmission of the third PUCCH information and the third PUSCH information.

If the transmission indication information supports simultaneous transmission of the PUCCH information and the PUSCH information, transmission of the PUCCH information and the PUSCH information in respective cells is reserved, and mutual transmission cannot be influenced.

As shown in fig. 9, uplink information in different cells includes UCI1 transmitted in PCell and PUSCH1 transmitted in Scell1, and UCI1 and PUSCH1 are transmitted simultaneously, that is, UCI1 is still transmitted through PCell and PUSCH1 is still transmitted through Scell1, which do not affect each other.

404. And detecting whether the third PUCCH information meets multiplexing conditions with second target PUSCH information transmitted in other cells, if so, executing step 405, and if not, executing step 406.

If the transmission indication information does not support simultaneous transmission of the PUCCH information and the PUSCH information, multiplexing the PUCCH information with PUSCH information transmitted in other cells is preferentially considered. And sequentially detecting whether the other cells have the reusable PUSCH information or not according to the sequence of the cell sequence numbers from small to large.

As shown in fig. 9, it is first detected whether PUSCH1 and UCI1 transmitted in SCell1 satisfy the multiplexing condition, and if so, step 405 is executed, and if not, it is continuously detected whether PUSCH2 and UCI1 transmitted in SCell2 satisfy the multiplexing condition, and if so, step 405 is executed, and if not, step 406 is executed.

405. Multiplexing the third PUCCH information with the second target PUSCH information.

And multiplexing the third PUCCH information and the second target PUSCH information and then transmitting the multiplexed information in the cell where the second target PUSCH information is located.

For example, as shown in fig. 9, if UCI1 and PUSCH1 transmitted in SCell1 satisfy the multiplexing condition, UCI1 and PUSCH1 are multiplexed and transmitted in SCell 1; if the multiplexing condition is not satisfied by UCI1 and PUSCH1 transmitted in SCell1, and the multiplexing condition is satisfied by UCI1 and PUSCH2 transmitted in SCell2, UCI1 and PUSCH2 are multiplexed and transmitted in SCell 2.

406. And processing the third PUCCH information and the third PUSCH information according to a priority strategy.

If the third PUCCH information and the PUSCH information transmitted in all other cells do not satisfy the multiplexing condition, a priority policy is adopted, the uplink information with high priority is retained from the third PUCCH information and the third PUSCH information to be transmitted in the cell corresponding to the third PUCCH information, and the uplink information with low priority is discarded, and if the priorities of a plurality of uplink information are the same, a policy of multiplexing NRrelease15 is adopted, or a policy of multiplexing NR subsequent versions is also adopted, which is not specifically limited herein.

For example, as shown in fig. 9, UCI1, PUSCH1, PUSCH2 do not satisfy multiplexing conditions, and UCI1 has higher priority than PUSCH1 and PUSCH2, transmission of UCI1 in PCell is reserved, and PUSCH1 and PUSCH2 are dropped.

In this embodiment, when the PUCCH information and the PUSCH information in different cells collide with each other, the multiplexing method is preferentially considered without affecting high-priority uplink transmission, so that the high-priority uplink transmission can be ensured, and the robustness of low-priority uplink transmission can be improved.

When the conflict type includes intra-cell conflict and inter-cell conflict, the intra-cell conflict and the inter-cell conflict need to be solved at the same time, a plurality of uplink information in the same cell may be processed according to the first transmission processing mode, so that only one uplink information or multiplexed uplink information is reserved in each cell, and then the uplink information still conflicting in different cells is processed according to the second transmission processing mode to solve the problem of multiple uplink transmission conflicts, which is not described in detail herein.

For example, as shown in fig. 5, the UCI1 and the PUSCH1 in the PCell are processed by the first transmission processing method, and if the UCI1 and the PUSCH1 satisfy the multiplexing condition, the UCI1 and the PUSCH1 are multiplexed. And meanwhile, processing the PUSCHs 2 and the PUSCHs 3 in the SCell1 by adopting a first processing mode, if other cells do not have idle resources corresponding to the PUSCHs 3, reserving the PUSCHs 2 with high priority, and discarding the PUSCHs 3 with low priority. Since the user equipment supports simultaneous transmission of multiple PUSCH information, the PCell no longer collides with uplink information in the SCell1, and then multiplexed UCI1 and PUSCH1 are transmitted in the PCell and PUSCH2 is transmitted in the SCell 1.

For example, as shown in fig. 6, PUSCH2 and PUSCH3 in SCell1 are processed by the first transmission processing method, and since SCell2 has idle resources, PUSCH3 with low priority is transmitted in SCell2, and PUSCH2 with high priority remains in SCell 1. And further, the UCI1 and the UCI2 in the PCell are processed by adopting a first transmission processing mode, the UCI1 with high priority is reserved in the PCell, and the UCI2 and the PUSCH3 with low priority meet multiplexing conditions, so that the UCI2 and the PUSCH3 are multiplexed in the SCell 2. After the uplink transmission collision processing in each cell is finished, if there is still collision between UCI1 reserved in the PCell and PUSCH2 reserved in SCell1, a second transmission processing mode is adopted to process UCI1 in the PCell and PUSCH2 in SCell1, and if UCI1 and PUSCH2 meet multiplexing conditions, UCI1 and PUSCH2 are multiplexed in SCell 1. After processing, multiplexed UCI1 and PUSCH2 are transmitted in SCell1, and multiplexed UCI2 and PUSCH3 are transmitted in SCell 2.

103. And transmitting the processed uplink information.

After the processing of step 102, if the PUCCH information remains in the original cell, the PUCCH information is still transmitted through the original cell, if the PUCCH information is multiplexed with the PUSCH information transmitted in the target cell, the PUCCH information is transmitted in the target cell after being multiplexed with the PUSCH information in the target cell, and if the PUCCH information is discarded, the PUCCH information is not transmitted. And if the PUSCH information is reserved in the original cell, the PUSCH information is still transmitted through the original cell, if the target idle resources of the target cell are reallocated by the PUSCH information, the PUSCH information is transmitted through the target cell, and if the PUSCH information is discarded, the PUSCH information is not transmitted.
