Description

Uplink data scheduling method, base station and user equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an uplink data scheduling method, a base station, and a user equipment.

Background

In the field of wireless Communication, an eNB (evolved NodeB) may communicate with a UE (user equipment) directly in a conventional manner when communicating with the UE, or may communicate with another UE near the UE to forward data of a target UE, and the two UEs communicate with each other through a short-range wireless Communication method (such as bluetooth and WiFi), which may be referred to as multi-UE (multi-UE composite Communication). The method can select the UE with the best channel condition from a plurality of UEs to transmit uplink and downlink data, thereby achieving the effect of multi-user diversity. Among them, the UE for the spin-up attack may be referred to as S-UE (Supporting UE), and the destination UE may be referred to as B-UE (Benefited UE).

The communication protocol stack of the MUCC is different from the conventional LTE (Long Term Evolution) protocol stack, and the MUCC protocol stack needs to add a synthesis layer and perform data transmission by using a short-distance wireless communication mode. In the prior art, the composite layer is added on a PDCP (Packet Data Convergence Protocol) layer, or between the PDCP layer and an RLC (Radio Link Control) layer.

Based on the protocol stack structure, the eNB can set a data distribution strategy in two UEs according to the quality of an uplink channel, B-UE generates data to be sent and distributes the data to S-UE for storage, the S-UE requests the eNB to send the uplink data, and the S-UE can send the data only after the eNB sends an uplink data permission to the S-UE according to the uplink data sending request of the S-UE. There is a large time delay from the generation of data to be sent by the B-UE to the transmission of data by the S-UE, and when the data of the B-UE is sent by the S-UE, the quality of an uplink channel of the S-UE may have changed, and the current offloading policy may not be applicable any more, and the offloading policy is not adjusted in time.

Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The uplink data scheduling method and the base station of the embodiment of the invention can be applied to an FDD-LTE network, the LTE (Long term Evolution) network can comprise two duplex modes of TDD (Time Division duplex) and FDD (Frequency Division duplex), and the LTE applying the FDD mode is the FDD-LTE. The uplink data scheduling method and the base station of the embodiment of the invention can be applied to a scene including, but not limited to, a MUCC system and a MU-MIMO (Multi-User Multi-Input Multi-Output) system. Before the specific technical solution of the embodiment of the present invention is introduced, a simple introduction is first performed on the MUCC system and the MU-MIMO system.

Both the MUCC system and the MU-MIMO system can be considered as a multi-UE cooperative communication system, and are shown in fig. 1, which is a schematic structural diagram of a MUCC or MU-MIMO system, wherein a base station eNB10 schedules two UEs 20 to transmit uplink data to the base station, and the two UEs can communicate with each other in a short-distance wireless communication manner. In the MUCC system, two UEs have a synthetic communication relationship, when data needs to be sent, one UE can forward the data needing to be sent by the other UE, the UE with the forwarding function is S-UE, and the target UE is B-UE. In the MU-MIMO system, both UEs may be used as B-UEs or S-UEs of the other side, and are in a synchronous state with the eNB, that is, these UEs may be regarded as a large UE with multiple antennas, each sub-UE may transmit uplink data by using the same time-frequency resource, and each sub-UE needs to have data to be transmitted before the sub-UE transmits the uplink data.

When implementing the MUCC or MU-MIMO technology, the protocol stack needs to add a synthesis layer. The main functions of the composite layer on the B-UE are data packet shunting and data packet transmission to the S-UE in a short-distance wireless communication mode; the main function of the composite layer on the S-UE is to receive each data packet from the B-UE in a short-distance wireless communication mode and to map the data packet to a certain composite bearer on the S-UE for uplink data transmission according to the packet header information added on the composite layer of the S-UE. A new Protocol stack structure is proposed, in which a synthetic layer is considered to be moved down, the synthetic layer is placed in a Medium Access Control (MAC) layer, and when the synthetic layer is moved down to the MAC layer, a Protocol Data Unit (MAC PDU) is transmitted between UEs through a short-distance wireless communication method.

In addition, it should be noted that each UE in the MUCC system can only generate one MAC PDU within one TTI, and can only transmit one MAC PDU; however, in the MU-MIMO system, each UE may generate one or two MAC PDUs within one TTI (Transmission Time Interval), and each pair of UEs may cooperatively transmit two MAC PDUs, that is, each pair of UEs individually generates one MAC PDU and cooperatively uploads, or one UE generates two MAC PDUs and cooperatively uploads the two MAC PDUs with another UE, but when one UE itself uploads a MAC PDU, it is similar to the MUCC system, and only one MAC PDU may be generated within one TTI, and only one MAC PDU may be transmitted, specifically, what manner the UE employs to upload data is scheduled by the base station.

After the MUCC or MU-MIMO system shown in FIG. 1 is constructed, in order to solve the problem that the uplink data offloading strategy adjustment in the prior art is not timely, and meanwhile, since the synthesis layer moves down to the MAC layer, the MAC layer does not have a buffer and cannot store the MAC PDU, the B-UE cannot offload data to the S-UE for storage, and the following uplink data scheduling method is provided in the embodiment of the present invention.

Referring to fig. 2, which is a flowchart of an uplink data scheduling method in embodiment 1 of the present invention, this embodiment may be applied to an MUCC system, and the method implemented in a base station in this embodiment may include the following steps:

step 101: and the base station sends the uplink scheduling information to the S-UE and the B-UE so that the B-UE generates the MAC PDU required to be sent according to the uplink scheduling information and obtains an uploading data mode of the MAC PDU required to be sent.

Here, it may be assumed that the base station eNB already knows the synthetic relationship of each UE, knows that the B-UE has data to transmit and the size of the data to transmit, and knows the C-RNTI (Cell Radio network temporary Identifier) of the other UE between the UEs. The base station may schedule the S-UE to forward data for the B-UE or transmit data directly to the base station by the B-UE in each TTI.

Specifically, the uplink scheduling information sent by the base station may at least include data generation identification information and data sending prompt information. The data generation identification information may prompt which UE generates the MAC PDU and the number of generated MAC PDUs, and since this embodiment is applied to the MUCC scenario, each UE may only generate one MAC PDU according to the data generation identification information within one TTI, and may only transmit one MAC PDU. The data transmission prompt message may indicate whether uplink data is transmitted by the UE that generates the data itself or by the S-UE in cooperation. The process of sending uplink data to the base station by the UE is similar to the traditional method for directly sending the uplink data, so the embodiment of the invention mainly introduces a scheduling method for sending the uplink data to the base station by the B-UE through the S-UE. Further, the uplink scheduling information may further include receiving identification information, and the receiving identification information may prompt which UE receives the uplink scheduling information.

Then, the base station sends the uplink scheduling information to the S-UE and the B-UE, the B-UE may generate the MAC PDU to be sent according to the data generation identification information, and obtain the data uploading mode according to the data sending prompt information, where the data uploading mode of the MAC PDU to be sent may be data uploading through the S-UE or data direct uploading.

Step 102: and if the data uploading mode is to upload data through the S-UE, the base station receives the MAC PDU sent by the S-UE, and the MAC PDU sent by the S-UE is obtained after the S-UE receives the MAC PDU sent by the B-UE through the short-distance wireless communication mode.

Because the MAC PDU can be generated and transmitted only after the UE obtains the uplink scheduling information, the embodiment of the invention can directly receive the data uploaded by the S-UE by the base station eNB after the B-UE transmits the MAC PDU to the S-UE, reduces the interval from the generation of the MAC PDU by the B-UE to the transmission of the data to the base station through the S-UE, and the scheduling of the base station can timely adjust the change of the uplink channel condition. The short-range wireless communication method includes, but is not limited to, bluetooth, wifi (wireless fidelity), and the like.

The embodiment of the method can be applied to an MUCC system, and in addition, the UE can flexibly upload data according to the uplink scheduling information by utilizing the mode that the base station sends the uplink scheduling information, thereby realizing the purpose of flexibly scheduling the uplink data by the base station.

Referring to fig. 3, a flowchart of an uplink data scheduling method in embodiment 2 of the present invention is shown, where the flowchart includes:

step 201: and the base station sends the uplink scheduling information to the S-UE and the B-UE so that the B-UE generates the MAC PDU required to be sent according to the uplink scheduling information and obtains an uploading data mode of the MAC PDU required to be sent.

Step 202: and if the data uploading mode is to upload data through the S-UE, the base station receives the MAC PDU sent by the S-UE, and the MAC PDU sent by the S-UE is obtained after the S-UE receives the MAC PDU sent by the B-UE through the short-distance wireless communication mode.

Step 203: after receiving the MAC PDU sent by the S-UE, the base station sends Acknowledgement (ACK) to the S-UE, or sends Negative Acknowledgement (NACK) to the S-UE, so that the S-UE retransmits the MAC PDU according to the Negative Acknowledgement.

It should be noted that, after receiving the MAC PDU sent by the B-UE, the S-UE may send the received MAC PDU to a corresponding HARQ (Hybrid Automatic Repeat reQuest) process, so that when the base station feeds back data that is not correctly received and sent by the S-UE, the S-UE may directly resend the data that is not successfully transmitted.

Step 204: and the base station receives the MAC PDU retransmitted by the S-UE.

The steps 201-202 are similar to the steps 101-102, and are not described herein again. Compared with the method embodiment 1, in this embodiment, after the base station receives the MAC PDU sent by the S-UE, the base station further sends acknowledgement information or negative acknowledgement information to the S-UE according to the received MAC PDU, so that the S-UE resends the MAC PDU according to the negative acknowledgement information, and the base station receives the MAC PDU resent by the S-UE, so as to ensure correct transmission of uplink data.

Referring to fig. 4, which is a flowchart of an uplink data scheduling method in embodiment 3 of the present invention, this embodiment may be applied to an MUCC system, and the implementation of this embodiment in a B-UE may include the following steps:

step 301: and B-UE receives the uplink scheduling information.

The uplink scheduling information received by the B-UE may include at least: the data generation identification information and the data sending prompt information.

Step 302: and B-UE generates the MAC PDU required to be sent according to the uplink scheduling information and obtains the data uploading mode of the MAC PDU required to be sent.

Specifically, the B-UE may generate the mac pdu to be sent according to the data generation identification information; and confirming the data uploading mode of the MAC PDU needing to be sent according to the data sending prompt information.

Step 303: and if the data uploading mode is to upload data through the S-UE, the B-UE sends the MAC PDU to the S-UE through the short-distance wireless communication mode so that the S-UE sends the MAC PDU to the base station.

Further, the uplink scheduling information may further include receiving identification information, and according to the receiving identification information, the B-UE may receive the uplink scheduling information sent by the base station; or the B-UE receives the uplink scheduling information forwarded by the S-UE. Specifically, the B-UE determines whether to receive uplink scheduling information sent by the base station according to the reception identification information, and further, the B-UE determines whether the reception identification information stored in the B-UE itself includes the reception identification information according to the reception identification information.

For example, the uplink scheduling information carries the identity information of the B-UE as the receiving identification information, then both the S-UE and the B-UE receive the uplink scheduling information from the base station, that is, the B-UE receives the uplink scheduling information sent by the base station; and the uplink scheduling information carries the identity information of the S-UE as the receiving identification information, and the S-UE receives the uplink scheduling information from the base station and forwards the uplink scheduling information to the B-UE, namely the B-UE receives the uplink scheduling information forwarded by the S-UE.

The embodiment of the method can be applied to an MUCC system, corresponds to the embodiment 1-2 of the method, takes B-UE as an execution main body, and utilizes a base station to send uplink scheduling information, so that the UE can flexibly upload data, and the aim of flexibly scheduling the uplink data by the base station is fulfilled.

Referring to fig. 5, which is a flowchart of an uplink data scheduling method in embodiment 4 of the present invention, this embodiment may be applied to an MUCC system, and the implementation of this embodiment in an S-UE may include the following steps:

step 401: and the S-UE receives the uplink scheduling information.

The uplink scheduling information received by the S-UE may include at least: the data generation identification information and the data sending prompt information.

Step 402: and the S-UE determines an uploading data mode according to the uplink scheduling information.

Step 403: and if the data uploading mode is to upload data through the S-UE, the S-UE receives the MAC PDU which is sent by the beneficial user equipment B-UE through the short-distance wireless communication mode, and the MAC PDU is generated by the B-UE according to the uplink scheduling information.

Specifically, the S-UE may determine a data uploading manner according to the data sending prompt information, and determine that the data uploading manner of the MACPDU to be sent is to upload data through the S-UE; before the S-UE receives the MAC PDU sent by the B-UE through the short-range wireless communication mode, the method may further include: and the S-UE confirms that the received MAC PDU is the MAC PDU generated by the B-UE corresponding to the S-UE according to the data generation identification information.

Step 404: the S-UE transmits the MAC-PDU to the base station.

Further, the S-UE can also forward the uplink scheduling information to the B-UE. The uplink scheduling information may further include receiving identification information, and the S-UE may determine whether to forward the uplink scheduling information to the B-UE according to the receiving identification information. For example, the uplink scheduling information carries the identity information of the S-UE as the receiving identification information, the S-UE receives the uplink scheduling information from the base station, and the S-UE can confirm to forward the uplink scheduling information to the B-UE according to the receiving identification information.

The embodiment of the method can be applied to an MUCC system, corresponds to the embodiment 1-2 of the method, takes S-UE as an execution main body, and utilizes a base station to send uplink scheduling information, so that the UE can flexibly upload data, and the aim of flexibly scheduling the uplink data by the base station is fulfilled.

Based on method embodiments 1 to 4, referring to fig. 6, a flowchart of an uplink data scheduling method embodiment 5 according to an embodiment of the present invention is shown, including:

step 501: the base station sends uplink scheduling information to the S-UE and the B-UE, wherein the identity information of the B-UE is used as receiving identification information and data generation identification information so that the S-UE and the B-UE receive the uplink scheduling information, the B-UE generates MAC PDU required to be sent according to the data generation identification information, and an uploading data mode of the MAC PDU required to be sent is obtained according to the data sending prompt information.

When the uplink scheduling information carries the identity information of the B-UE as the receiving identification information and the data generation identification information, for example, the uplink scheduling information is scrambled by using the C-RNTI of the B-UE, both the S-UE and the B-UE receive the uplink scheduling information. When one B-UE corresponds to one S-UE, the uplink scheduling information may indicate whether the B-UE uploads data to the base station or uploads data through the S-UE, and when one B-UE corresponds to a plurality of S-UEs, the uplink scheduling information may indicate whether the B-UE uploads data to the base station or uploads data through the S-UE, specifically, through which S-UE the data is uploaded. When one B-UE corresponds to one S-UE, the uplink scheduling information can adopt a flag bit to indicate whether the B-UE uploads data to the base station or uploads the data through the S-UE; when one B-UE corresponds to a plurality of S-UEs, the data sending prompt information can comprise C-RNTIs of the S-UEs and also can comprise a pre-configured transmission path corresponding table, and the table comprises an index value of each S-UE of the B-UEs, so that the uplink scheduling information can indicate whether the B-UEs upload data to the base station or upload data through which S-UE.

Step 502: and if the data uploading mode is to upload data through the S-UE, the base station receives the MAC PDU sent by the S-UE, and the MAC PDU sent by the S-UE is obtained after the S-UE receives the MAC PDU sent by the B-UE through the short-distance wireless communication mode.

Step 503: after receiving the MAC PDU sent by the S-UE, the base station sends acknowledgement information ACK to the S-UE or sends negative acknowledgement information NACK to the S-UE, so that the S-UE resends the MAC PDU according to the negative acknowledgement information.

Step 504: and the base station receives the MAC PDU retransmitted by the S-UE.

Corresponding to the foregoing data scheduling method embodiment 5, an embodiment 1 of the present invention further provides an uplink data scheduling system, including a base station eNB, a B-UE, and an S-UE. The functions of the above-mentioned parts and the information interaction process between the parts are briefly described with reference to the signaling interaction diagram shown in fig. 7.

Step 601: the base station sends uplink scheduling information to S-UE and B-UE, wherein the identity information of the B-UE is used as receiving identification information and data generation identification information, and the S-UE and the B-UE both receive the uplink scheduling information.

Step 602: B-UE generates the MAC PDU which needs to be sent according to the data generation identification information, and obtains the uploading data mode of the MAC PDU which needs to be sent according to the data sending prompt information.

Step 603: and if the data uploading mode is to upload data through the S-UE, the B-UE sends the MAC PDU to the S-UE through the short-distance wireless communication mode.

Step 604: the S-UE sends MAC PDU to the base station, and the base station receives the MAC PDU.

Step 605: the base station sends acknowledgement information ACK to the S-UE or negative acknowledgement information NACK to the S-UE.

Step 606: and if the MAC PDU needs to be retransmitted, the S-UE retransmits the MAC PDU to the base station according to the negative acknowledgement information, and the base station receives the MAC PDU retransmitted by the S-UE.

In the conventional scheduling method, the interval from the time when the base station sends the scheduling information to the S-UE to the time when the base station receives the uplink data sent by the S-UE is 4ms, however, in the embodiment of the present invention, the time when the MAC PDU is wirelessly communicated between the UEs through a short distance needs to be considered, and if the forwarding delay time when the B-UE sends the MAC PDU to the S-UE is 1ms, the base station receives the MAC PDU after 5ms after sending the scheduling information to the UE in the embodiment of the present invention.

It should be noted that, if it is assumed that the time when the base station transmits the uplink scheduling information to the UE is N time, and when the data uploading mode of the B-UE is data uploading through the S-UE, the time when the base station receives the MAC PDU sent by the S-UE is N +5 time, the base station needs to avoid scheduling the S-UE to directly upload the data of the S-UE to the base station at N +5 time at N +1 time. Meanwhile, the specific occurrence time of each step may be set according to actual conditions, and the figure only shows an example, which is not limited in the embodiment of the present invention.

Based on method embodiments 1 to 4, referring to fig. 8, a flowchart of an embodiment 6 of an uplink data scheduling method according to an embodiment of the present invention is shown, where the flowchart includes:

step 701: the base station sends uplink scheduling information to S-UE and B-UE, wherein the identity information of the S-UE is used as receiving identification information and data sending prompt information, so that the S-UE receives the uplink scheduling information and forwards the uplink scheduling information to the B-UE in a short-distance wireless communication mode, the B-UE generates an MAC PDU (media access control protocol data unit) required to be sent according to the data generating identification information, and an uploading data mode of the MAC PDU required to be sent is obtained according to the data sending prompt information.

When the uplink scheduling information carries the identity information of the S-UE as the receiving identification information and the data sending prompt information, for example, the uplink scheduling information is scrambled by using the C-RNTI of the S-UE, only the S-UE receives the uplink scheduling information. The data generation identification information may include a C-RNTI of the B-UE, and may also include a pre-configured transmission path mapping table including an index value of each B-UE of the S-UE. The S-UE needs to forward the uplink scheduling information to the B-UE through a short-distance wireless communication mode according to the uplink scheduling information, and the B-UE can generate the MAC PDU needing to be sent and an uploading data mode of uploading data through the S-UE according to the uplink scheduling information.

Step 702: when the data uploading mode is data uploading through the S-UE, the base station receives the MAC PDU sent by the S-UE, and the MAC PDU sent by the S-UE is obtained after the S-UE receives the MAC PDU sent by the B-UE through the short-distance wireless communication mode.

Step 703: after receiving the MAC PDU sent by the S-UE, the base station sends acknowledgement information ACK to the S-UE, or sends negative acknowledgement information NACK to the S-UE, so that the S-UE resends the MAC PDU according to the negative acknowledgement information.

Step 704: and the base station receives the MAC PDU retransmitted by the S-UE.

Step 702-704 is similar to step 502-504, and will not be described herein. Compared with the method embodiment 5, in this embodiment, if the information carried in the uplink scheduling information is different, only the S-UE receives the uplink scheduling information, and the S-UE forwards the uplink scheduling information to the B-UE, thereby completing the subsequent uplink data scheduling. In addition, the uplink scheduling information is received by the B-UE and the S-UE simultaneously or the uplink scheduling information is received by the S-UE, and then the uplink scheduling information is forwarded to the B-UE by the S-UE, so that the base station can configure the uplink scheduling information when the synthetic relation is established between the UEs.

Similarly, corresponding to the data scheduling method embodiment 6, an embodiment 2 of the present invention further provides an uplink data scheduling system, which includes a base station eNB, a B-UE, and an S-UE. The functions of the above-mentioned parts and the information interaction process between the parts are briefly described with reference to the signaling interaction diagram shown in fig. 9.

Step 801: and the base station transmits uplink scheduling information to the S-UE and the B-UE, wherein the identity information of the S-UE is used as receiving identification information and data transmission prompt information, and only the S-UE receives the uplink scheduling information.

Step 802: and the S-UE forwards the uplink scheduling information to the B-UE in a short-distance wireless communication mode.

Step 803: B-UE generates the MAC PDU which needs to be sent according to the data generation identification information, and obtains the uploading data mode of the MAC PDU which needs to be sent according to the data sending prompt information.

Step 804: and if the data uploading mode is to upload data through the S-UE, the B-UE sends the MAC PDU to the S-UE through the short-distance wireless communication mode.

Step 805: the S-UE sends MAC PDU to the base station, and the base station receives the MAC PDU.

Step 806: the base station sends acknowledgement information ACK to the S-UE or negative acknowledgement information NACK to the S-UE.

Step 807: and if the MAC PDU needs to be retransmitted, the S-UE retransmits the MAC PDU to the base station according to the negative acknowledgement information, and the base station receives the MAC PDU retransmitted by the S-UE.

Assuming that the forwarding delay time for the S-UE to send the uplink scheduling information to the B-UE is 1ms, and the forwarding delay time for the B-UE to send the mac pdu to the S-UE is 1ms, the base station receives the mac pdu after 6ms after sending the scheduling information to the UE in the embodiment of the present invention. It should be noted that the specific occurrence time of each step may be set according to actual situations, and the illustration is only an example, which is not limited by the embodiment of the present invention.

On the basis of the above embodiments, the base station eNB schedules the B-UE to forward data through the S-UE, but at this time, the quality of the short-distance wireless communication link between the B-UE and the S-UE may not be good, and the mac pdu of the B-UE may not be successfully transmitted. Therefore, a corresponding timer can be set at the S-UE side, if the MAC PDU from the B-UE is received before the timeout, the MAC PDU is normally forwarded, and the timer is stopped; and if the timer is overtime, the short-distance wireless communication link between the B-UE and the S-UE is considered to be broken, the waiting is not required to be continued, and the uplink scheduling information stored before is discarded. Therefore, uplink time-frequency resources allocated by the base station eNB are blank, and the base station eNB can be implicitly informed of unsuccessful forwarding through the mode, so that the base station eNB does not need to request retransmission.

Further, when the timer of the S-UE expires, the S-UE may construct a MAC PDU, which includes a special MAC CE (MAC Control Element), and the rest is a padding bit. The MAC PDU is sent on an uplink time-frequency resource designated by the base station eNB. When the base station receives the MAC PDU, the base station can know that the data forwarding from the B-UE to the S-UE is unsuccessful by reading the special MAC CE in the MAC PDU.

Further, when the timer of the S-UE expires, the S-UE generates a MAC PDU of its own, which includes its identity information, such as a flag bit, or a MAC ce including its C-RNTI, and in this way, informs the eNB that the data of the S-UE is not the data of the B-UE. The MAC PDU is sent on uplink time-frequency resources designated by the eNB. When the base station receives the MAC PDU, the identity information of the S-UE in the MAC PDU is read, so that the base station can know that the MAC PDU is data of the S-UE and not data of B-UE, and the base station can know that the data forwarding from the B-UE to the S-UE is unsuccessful.

In addition, the B-UE can also know that the quality of the short-distance wireless communication link between the B-UE and the S-UE is not good or the mac pdu of the B-UE is not successfully transmitted to the S-UE, and then the B-UE can transmit data to the base station eNB by using the previously received uplink scheduling information.

The above cases can also be used for the base station to detect the quality of the short-distance wireless communication link between the UEs.

Referring to fig. 10, which is a flowchart of an uplink data scheduling method in embodiment 7 of the present invention, this embodiment may be applied to an MU-MIMO system, and the implementation of this embodiment in a base station may include the following steps:

step 901: and the base station sends uplink scheduling information to the first UE and the second UE so that the first UE and/or the second UE generate the MAC PDU which needs to be sent according to the uplink scheduling information.

Here, it is assumed that the base station eNB already knows the composition relationship of each UE, which UE has data to transmit and the size of the data to transmit, and knows the C-RNTI of the other UE between UEs. Data transmission by a single UE or joint transmission by multiple UEs is scheduled by the base station in each TTI.

Specifically, the uplink scheduling information may include at least data generation identification information and data transmission prompt information. The data generation identification information may prompt which UE generates the MAC PDU and the number of generated MAC PDUs, and since the embodiment is applied to the MU-MIMO scenario, one or two MAC PDUs can be generated by each UE within one TTI according to the data generation identification information. The data transmission prompt message may indicate whether uplink data is transmitted by the UE that generates the data itself or by two UEs in cooperation, specifically, which UE is to transmit the uplink data in cooperation. Similarly, the embodiment of the present invention focuses on a scheduling method for two UEs to cooperatively send uplink data to a base station.

Then, the base station sends uplink scheduling information to the first UE and the second UE, and the first UE and/or the second UE generates the MAC PDU to be sent according to the data generation identification information, and obtains the data uploading mode according to the data sending prompt information.

Step 902: the base station receives MAC PDU which is cooperatively sent by first UE and second UE in an MU-MIMO communication mode, wherein the MAC PDU is obtained after the first UE and the second UE are shared in a short-distance wireless communication mode; the MU-MIMO communication mode is determined by the way that the first UE and the second UE search the uploading data stored by the first UE and the second UE according to the uplink scheduling information.

Because the MAC PDU can be generated and transmitted only after the UE obtains the uplink scheduling information, the embodiment of the invention can ensure that the base station directly receives the data cooperatively uploaded by the two UEs after the two UEs share the MAC PDU, thereby shortening the time interval from the generation of the data MAC PDU needing to be transmitted by the UE to the cooperative transmission of the data to the base station by the other UE.

Compared with the method embodiment 1, the method embodiment can be applied to a MU-MIMO system, does not distinguish between S-UE and B-UE, and when two UEs upload data cooperatively, the base station can schedule any one of the two UEs to generate two MAC PDUs within one TTI, and then the two UEs upload the two MAC PDUs cooperatively, or schedule the first UE and the second UE to generate one MAC PDU respectively, and then the two UEs upload the two MAC PDUs cooperatively. When uploading data cooperatively, two UEs need to share the MAC PDU to be sent first, and then cooperatively send the MAC PDU to the base station. It should be noted that, when the UE uploads data to the base station directly, the base station can only schedule the UE to upload one MAC PDU generated by the UE in one TTI, which is similar to the prior art.

Referring to fig. 11, a flowchart of an uplink data scheduling method in embodiment 8 of the present invention is shown, where the flowchart includes:

step 1001: and the base station sends uplink scheduling information to the first user equipment UE and the second UE so that the first UE and/or the second UE generate the MAC PDU which needs to be sent according to the uplink scheduling information.

Step 1002: the base station receives MAC PDU which is cooperatively sent by first UE and second UE in an MU-MIMO communication mode, wherein the MAC PDU is obtained after the first UE and the second UE are shared in a short-distance wireless communication mode; the MU-MIMO communication mode is determined by the way that the first UE and the second UE search the uploading data stored by the first UE and the second UE according to the uplink scheduling information.

Step 1003: after receiving the MAC PDU cooperatively sent by the first UE and the second UE, the base station sends acknowledgement information to the first UE and the second UE, or sends negative acknowledgement information to the first UE and the second UE, so that the first UE and/or the second UE resends the MAC PDU according to the negative acknowledgement information.

Step 1004: and the base station receives the MAC PDU retransmitted by the first UE and/or the second UE.

The steps 1001 and 1002 are similar to the steps 901 and 902, and are not described herein again. Compared with method embodiment 7, in this embodiment, after the MAC PDU cooperatively sent by the first UE and the second UE, the method further includes sending acknowledgement information or negative acknowledgement information to the first UE and the second UE according to the received MAC PDU, if both MAC PDUs need to be retransmitted, the MAC PDU is cooperatively retransmitted according to an initial transmission mode, that is, the first UE and the second UE, and if only one MAC PDU needs to be retransmitted, the UE that generates the MAC PDU retransmits the MAC PDU to the base station eNB by itself.

Corresponding to the foregoing data scheduling method embodiment 8, an embodiment 3 of the present invention further provides an uplink data scheduling system, including a base station eNB, a first UE, and a second UE. The functions of the above-mentioned parts and the information interaction process between the parts are briefly described with reference to the signaling interaction diagram shown in fig. 12.

Step 1101: and the base station sends uplink scheduling information to the first user equipment UE and the second UE.

Step 1102: and the first UE and/or the second UE generate a media access control layer protocol data unit (MAC PDU) which needs to be sent according to the uplink scheduling information.

Step 1103: the first UE and the second UE share the MACPDU through a short-distance wireless communication mode.

Step 1104: the first UE and the second UE cooperatively send MAC PDU through an MU-MIMO communication mode, and the base station receives the MAC PDU cooperatively sent by the first UE and the second UE through the MU-MIMO communication mode.

Step 1105: and the base station sends confirmation information to the first UE and the second UE or sends non-confirmation information to the first UE and the second UE.

Step 1106: and if the MAC PDU needs to be retransmitted, the first UE and/or the second UE resends the MAC PDU according to the negative acknowledgement information, and the base station receives the MAC PDU resent by the first UE and/or the second UE.

In the conventional scheduling method, the interval from the time when the base station sends the scheduling information to the UE to the time when the base station receives the uplink data sent by the UE is 4ms, however, in the embodiment of the present invention, the time when the MAC PDU is wirelessly communicated between the UEs through a short distance needs to be considered, and assuming that the delay time when two UEs share the MAC PDU is 1ms, the base station receives the MAC PDU after 5ms after sending the scheduling information to the UE in the embodiment of the present invention.

It should be noted that, if it is assumed that the time when the base station sends the uplink scheduling information to the UE is time N, when the data uploading manner of the first UE and/or the second UE is that the first UE and the second UE cooperatively upload data, the time when the base station receives the MAC PDU cooperatively sent by the first UE and the second UE is time N +5, the base station needs to avoid scheduling the first UE to directly upload the data of the first UE to the base station at time N +5 at time N +1, or scheduling the second UE to directly upload the data of the second UE to the base station at time N +5 at time N + 1. Meanwhile, the specific occurrence time of each step may be set according to actual conditions, and the figure only shows an example, which is not limited in the embodiment of the present invention.

Referring to fig. 13, which is a flowchart of an uplink data scheduling method embodiment 9 in the embodiment of the present invention, this embodiment may be applied to an MU-MIMO system, and this embodiment is applied to only one UE generating a MAC PDU according to uplink scheduling information, where the method is implemented in a UE generating the MAC PDU, and may include the following steps:

step 1201: one UE receives uplink scheduling information.

The received uplink scheduling information may include at least: the data generation identification information and the data sending prompt information.

Step 1202: and one UE generates the MAC PDU needing to be sent according to the uplink scheduling information.

Specifically, one UE generates at least one MAC PDU to be transmitted according to the data generation identification information.

Step 1203: and one UE searches the uploading data mode stored by the UE according to the uplink scheduling information to determine that the uploading data mode is the MU-MIMO communication mode.

Specifically, one UE obtains a data uploading mode of the MAC PDU to be transmitted according to the data transmission prompt information.

Step 1204: one UE sends MAC PDU to another UE through short distance wireless communication mode, so that another UE can obtain MAC PDU, and after confirming the uploading data mode, communicates with the base station.

Step 1205: one UE transmits MAC PDU to the base station through MU-MIMO communication mode.

Further, a UE may also receive the negative acknowledgement message, and a UE may retransmit the mac pdu according to the negative acknowledgement message.

The embodiment of the method can be applied to an MU-MIMO system, and when two UEs upload data cooperatively, a base station can schedule any one of the two UEs to generate two MAC PDUs in one TTI. The embodiment of the method takes the UE generating the MAC PDU as an execution main body, and achieves the purpose that the base station flexibly schedules the uplink data.

Referring to fig. 14, which is a flowchart of an embodiment 10 of an uplink data scheduling method in the embodiment of the present invention, this embodiment may be applied to an MU-MIMO system, and this embodiment is applied to only one UE generating a MAC PDU according to uplink scheduling information, and the method is implemented in a UE that does not generate a MAC PDU, and may include the following steps:

step 1301: one UE receives uplink scheduling information.

The received uplink scheduling information may include at least: and generating identification information by the data and sending prompt information by the data.

Step 1302: and one UE confirms that the UE does not generate the MAC PDU according to the uplink scheduling information.

Specifically, a UE determines that it is not the source of the MAC PDU according to the data generation identification information.

Step 1303: and one UE searches the uploading data mode stored by the UE according to the uplink scheduling information to determine that the uploading data mode is the MU-MIMO communication mode.

Step 1304: one UE interacts with the other UE in a short-distance wireless communication mode, so that the one UE acquires the MAC PDU of the other UE and communicates with the base station after the data uploading mode is confirmed.

Step 1305: one UE transmits MAC PDU to the base station through MU-MIMO communication mode.

Further, a UE may receive the negative acknowledgement information, and a UE may retransmit the mac pdu according to the negative acknowledgement information.

The embodiment of the method can be applied to an MU-MIMO system, and when two UEs upload data cooperatively, a base station can schedule any one of the two UEs to generate two MAC PDUs in one TTI. The embodiment of the method takes the UE which does not generate the MAC PDU as an execution main body, and achieves the purpose of flexibly scheduling the uplink data by the base station.

Referring to fig. 15, which is a flowchart of an uplink data scheduling method embodiment 11 in the embodiment of the present invention, this embodiment may be applied to an MU-MIMO system, and this embodiment is applied to two UEs both generating MAC PDUs according to uplink scheduling information, and implementing the method on two UE sides may include the following steps:

step 1401: one user equipment UE receives uplink scheduling information with another UE.

Step 1402: and one UE and the other UE respectively generate the MAC PDU which needs to be sent according to the uplink scheduling information.

Specifically, one UE and the other UE generate a mac pdu to be sent according to the data generation identification information.

Step 1403: and one UE and the other UE search the uploading data mode stored by the UE according to the uplink scheduling information to determine that the uploading data mode is the MU-MIMO communication mode.

Specifically, one UE and the other UE search for the data uploading mode stored by the UE according to the data sending prompt information to determine that the data uploading mode is the MU-MIMO communication mode.

Step 1404: one UE and the other UE interact MACPDU through a short-range wireless communication mode.

Step 1405: and MAC PDUs transmitted by one UE and the other UE to the base station in an MU-MIMO communication mode.

One UE and another UE may also receive the negative acknowledgement information, and one UE and another UE may retransmit the MAC PDU based on the negative acknowledgement information.

The embodiment of the method can be applied to an MU-MIMO system, and when two UEs upload data cooperatively, a base station can schedule the two UEs to generate one MAC PDU in one TTI respectively. The embodiment of the method takes two pieces of UE generating MAC PDU as an execution main body, and realizes the purpose of flexibly scheduling uplink data by a base station.

Based on the foregoing method embodiment, referring to fig. 16, a flowchart of an uplink data scheduling method embodiment 12 according to an embodiment of the present invention is shown, where the flowchart includes:

step 1501: the base station sends uplink scheduling information to the first UE and the second UE, wherein the data generation identification information can carry identity information of the first UE, so that the first UE and the second UE receive the uplink scheduling information, the first UE generates at least one MAC PDU (media access control protocol data unit) required to be sent according to the data generation identification information, and an uplink data uploading mode is obtained according to the data sending prompt information;

similarly, the base station sends uplink scheduling information to the first UE and the second UE, where the data generation identification information may carry identity information of the second UE, so that the first UE and the second UE receive the uplink scheduling information, the second UE generates at least one MAC PDU to be sent according to the data generation identification information, and obtains an upload data mode according to the data sending prompt information.

When the data transmission prompting information prompts that the data uploading mode of the MAC PDU needing to be transmitted is that the first UE and the second UE upload data cooperatively in an MU-MIMO communication mode, the data generation identification information carrying the identity information of the first UE (for example, the uplink scheduling information is scrambled by using C-RNTI of the first UE) can schedule the first UE to generate two MAC PDUs needing to be transmitted or the data generation identification information carrying the identity information of the second UE (for example, the uplink scheduling information is scrambled by using C-RNTI of the second UE) can schedule the second UE to generate two MAC PDUs needing to be transmitted. Meanwhile, the data sending prompt message may also include a C-RNTI of another UE, or may also include a pre-configured transmission path mapping table, where the table includes index values of other UEs having a synthetic relationship with one UE. It should be noted that, when the first UE only has a composite relationship with the second UE and the data transmission prompt message prompts the two UEs to upload data cooperatively, it represents that a UE already knows which UE to upload data cooperatively, and the data transmission prompt message may not include the C-RNTI of the other UE.

In addition, the data sending prompt message can also prompt the data uploading mode to upload data to the base station, and the data generation identification message can prompt the UE to generate an MAC PDU. This process is similar to the prior art and will not be described further herein.

Step 1502: the base station receives MAC PDU cooperatively sent by first UE and second UE in an MU-MIMO communication mode, wherein the MAC PDU cooperatively sent by the first UE and the second UE is obtained after the first UE and the second UE share the MAC PDU in a short-distance wireless communication mode; the MU-MIMO communication mode is determined by the way that the first UE and the second UE search the uploading data stored by the first UE and the second UE according to the uplink scheduling information.

Step 1503: after receiving the MAC PDU cooperatively sent by the first UE and the second UE, the base station sends confirmation information to the first UE and the second UE or sends denial information to the first UE and the second UE, so that the first UE and/or the second UE resends the MAC PDU according to the denial information.

Step 1504: and the base station receives the MAC PDU retransmitted by the first UE and/or the second UE.

The embodiment is directed to a case that two MAC PDUs to be sent are from the same UE, and the uplink scheduling information carries identity information of the UE, so that the two UEs can be scheduled to jointly complete cooperative upload of the two MAC PDUs.

Referring to fig. 17, a flowchart of an uplink data scheduling method 13 according to an embodiment of the present invention is shown, including:

step 1601: the base station sends uplink scheduling information to the first UE and the second UE, wherein the data generation identification information carries the identity information of the first UE and the identity information of the second UE, so that the first UE and the second UE receive the uplink scheduling information, the first UE and the second UE respectively generate an MAC PDU (media access control protocol data unit) which needs to be sent according to the data generation identification information, and an uplink data uploading mode is obtained according to the data sending prompt information.

When the data transmission prompting information prompts that the data uploading mode of the MAC PDU needing to be transmitted is that the first UE and the second UE upload data cooperatively in an MU-MIMO communication mode, the data generation identification information carries the identity information of the first UE and the identity information of the second UE (for example, the uplink scheduling information utilizes the C-RNTI of the first UE and contains the related identity information of the second UE), and then the first UE and the second UE respectively generate the MAC PDU needing to be transmitted. Meanwhile, the data sending prompt message may also include a C-RNTI of another UE, or may also include a pre-configured transmission path mapping table, where the table includes index values of other UEs having a synthetic relationship with one UE. It should be noted that, when the first UE only has a composite relationship with the second UE and the data transmission prompt message prompts the two UEs to upload data cooperatively, it represents that a UE already knows which UE to upload data cooperatively, and the data transmission prompt message may not include the C-RNTI of the other UE.

Step 1602: the base station receives MAC PDUs cooperatively transmitted by first UE and second UE in an MU-MIMO communication mode, the MAC PDUs cooperatively transmitted by the first UE and the second UE are obtained after the first UE and the second UE share the MAC PDUs in a short-distance wireless communication mode, and the MU-MIMO communication mode is determined by searching for self-stored uploading data mode by the first UE and the second UE according to uplink scheduling information.

Step 1603: after receiving the MAC PDU cooperatively sent by the first UE and the second UE, the base station sends confirmation information to the first UE and the second UE or sends denial information to the first UE and the second UE, so that the first UE and/or the second UE resends the MAC PDU according to the denial information.

Step 1604: and the base station receives the MAC PDU retransmitted by the first UE and/or the second UE.

The steps 1602-1604 and 1502-1504 are similar and will not be described herein. Compared with the method embodiment 12, in this embodiment, for a case that two MAC PDUs to be uploaded are from different UEs, information carried in uplink scheduling information is different, and the two UEs can be scheduled to jointly complete cooperative uploading of the two MAC PDUs.
