Description

Method, related equipment and system for controlling information processing

Technical Field

The present invention relates to the field of communications, and in particular, to a method, a related device, and a system for controlling information processing.

Background

With the development of mobile communication, Wearable Devices (WD) are expected to perform basic communication services, such as sending and receiving short messages, and the number of WD is expected to increase dramatically in the future. In order to prolong the endurance of the wearable device, the energy consumption of the wearable device should be reduced as much as possible.

One possible solution is that the WD does not need to directly send data to a base station at a longer distance, but may form a Device cooperation group with one or more Relay Devices (RD) at a shorter distance, and since the short-distance Device-to-Device (D2D) may greatly reduce the transmission power of the wearable Device, the uplink data of the wearable Device may be sent to the Relay Device by short-distance D2D communication, and then forwarded to the network by the Relay Device.

In a multi-user relay scenario, because multiple RDs need to perform Hybrid Automatic Repeat Request (HARQ) merging before decoding when forwarding Data for a certain WD, from the perspective of the RD, Data of different objects cannot be multiplexed in a Protocol Data Unit (PDU) of a Media Access Control (MAC). Referring to fig. 1, fig. 1 is a schematic diagram illustrating that a relay device cannot distinguish control information in the prior art, so that according to the prior art, an RD may send a plurality of buffer status reports (full english name: buffer status Report, abbreviated english: BSR) to a base station as data request resources of different objects. For example, in the case shown in fig. 1, RD1 needs to forward data of WD1 and WD2 to the base station, RD1 itself also has data to transmit to the base station, at this time, RD1 may transmit BSR0, BSR1, and BSR2 to the base station, BSR0 requests its own data resource for RD1, BSR1 requests forwarding of data resource of WD1 for RD1, and BSR2 requests forwarding of data resource of WD2 for RD 1.

In the prior art, after receiving the BSR0, the BSR1, and the BSR2, the base station performs priority processing according to Information in each BSR, and issues Downlink Control Information (DCI) corresponding to each BSR to the RD. Assuming that DCIs corresponding to BSR0, BSR1, and BSR2 are DCI0_0, DCI0_1, and DCI0_2, respectively, when a base station issues DCI0_0, DCI0_1, and DCI0_2 to RD1, due to a priority processing procedure at the base station side, RD1 cannot distinguish which BSR the three DCIs correspond to, and therefore, RD1 may not correspond data to be transmitted with corresponding control information in a data transmission procedure.

Disclosure of Invention

The embodiment of the invention provides a method, related equipment and a system for processing control information, which can enable first equipment to recognize the accurate direction of control information issued by a network side.

In view of the above, a first aspect of the present invention provides a method for controlling information processing, described from the perspective of a first device, including the following processes:

the first device first needs to receive first control information sent by the base station, where the first control information is obtained by the base station scrambling the second control information with the first identifier and the second identifier according to the resource request message, in other words, after the base station receives the resource request message sent by the first device, the base station scrambles the second control information with the first identifier and the second identifier together according to the received information, and obtains the first control information, and then sends the scrambled first control information to the first device, so that the first device can descramble the first control information with the first identifier and the second identifier, and obtain the second control information at the first device side, where the second control information is used for the first device to determine a data transmission resource required for forwarding data of the second device.

The embodiment of the invention provides a method for distributing control information, wherein first equipment for controlling information processing receives first control information sent by a base station, the first control information is obtained by scrambling second control information by using a first identifier and a second identifier according to a resource request message by the base station, and the first equipment descrambles the first control information by using the first identifier and the second identifier to obtain the second control information, wherein the second control information is used for determining data transmission resources required for forwarding data of second equipment by the first equipment. By adopting the method, the first equipment can obtain the second control information by descrambling the first control information after receiving the first control information, and finally can determine the data transmission resource required by forwarding the data of the second equipment according to the second control information, so that the first equipment can identify the accurate direction of the control information issued by the network side.

With reference to the first aspect of the embodiment of the present invention, in a first possible implementation manner, before the first device receives the first control information sent by the base station, the method may further include the following steps:

the first device sends a resource request message to the base station, wherein the resource request message is used for requesting the base station by the first device to forward data transmission resources required by data of the second device. Specifically, the resource request message may be a BSR, which is used to provide the base station with how much data the first device and the second device share in an uplink buffer to transmit.

Secondly, in the embodiment of the present invention, it is specifically described that the base station needs to receive the resource request message sent by the first device before performing the subsequent scrambling processing, and the resource request message is mainly used for requesting, by the first device, the base station to forward the data transmission resource required by the data of the second device. The base station determines which objects to request resources for data through the received resource request message, and the scrambling mode is unchanged, so that the scheme has stronger practicability, has directivity on scrambled contents, and simultaneously strengthens the feasibility of the scheme.

With reference to the first aspect of the embodiment of the present invention, in a second possible implementation manner, the first identifier is an identifier of a first device, the second identifier is an identifier of a cooperation group in which the second device is located, and the cooperation group includes one second device and at least one first device.

Specific contents of the first identifier and the second identifier are defined, the two identifiers are used simultaneously during scrambling, and during descrambling, the identifier of the first device is used for descrambling, and then the identifier of the cooperation group where the second device is located is used for descrambling for the second time on the basis of descrambling for the first time, so that whether the first control information is directed at data of the second device of a certain cooperation group is determined.

In the embodiment of the present invention, the meaning of the dual identifiers is specifically defined, the first identifier is an identifier of the first device itself, and the second identifier is an identifier of the cooperative group in which the second device is located, so that the first device performs descrambling processing on the first control information by using the identifier of the first device itself, so as to know whether the first control information is data for the first device itself, and if not, continues to perform descrambling processing by using the identifier of the cooperative group, and determines whether the first control information is data for the cooperative group, thereby ensuring that the first device can recognize an accurate direction of sending control information by the network side.

With reference to the first aspect, the first implementation manner of the first aspect, or the second implementation manner of the first aspect, in a third possible implementation manner, the performing, by the first device, descrambling processing on the first control information by using the first identifier and the second identifier to obtain the second control information may include the following steps:

first, the first device uses the first identifier to perform descrambling processing on the first control information, and according to the specific reference of the first identifier mentioned immediately above, it can be understood that the first device first uses its own identifier to perform descrambling processing on the first control information, and if the descrambling processing on the first control information using the first identifier fails, it indicates that the first control information is not for the first device, and then the first device obtains third control information, where the third control information is control information obtained after the first device uses the first identifier to perform descrambling processing on the first control information, that is, control information subjected to one descrambling. The first device further uses the second identifier to perform descrambling processing on the third control information, where the second identifier is also the identifier of the cooperation group where the second device is located, and if descrambling processing on the third control information using the second identifier is successful, the first device obtains the second control information.

Further, in the embodiment of the present invention, how the first device performs descrambling on the first control information by using the first identifier and the second identifier, and obtains the second control information is specifically described. And after the first control information is subjected to descrambling failure by using the first identifier, the first equipment adopts the second identifier to descramble on the basis of the first control information subjected to descrambling failure for the first time. Therefore, the first device can further distinguish whether the control information aims at the first device to forward the assisted second device data or not on the basis of not influencing the original behavior of the first device for receiving the control information. If the control information is for the first device to forward the data assisting the second device, on the premise that the first device can assist a plurality of second devices, the scheme of the invention can further distinguish which second device the first control information is for, thereby improving the practicability and flexibility of the scheme.

A second aspect of the present invention provides a method for controlling information processing, described from the perspective of a base station, comprising the following procedures:

firstly, a base station receives a resource request message sent by a first device to the base station, specifically, the resource request message may refer to a BSR, but is not limited to the BSR in practical application, and then the base station performs scrambling processing on second control information by using a first identifier and a second identifier according to the resource request message to obtain first control information, and then the base station sends the first control information to the first device, so that the first device performs descrambling processing on the first control information by using the first identifier and the second identifier to obtain second control information, wherein the second control information is used for the first device to determine a data transmission resource required for forwarding data of a second device.

In the embodiment of the present invention, a method for allocating control information is provided, in which a base station performs scrambling processing on second control information by using a first identifier and a second identifier according to a resource request message, and obtains first control information, and then sends the scrambled first control information to a first device, so that the first device performs descrambling processing on the first control information by using the first identifier and the second identifier, and obtains second control information, where the second control information is used by the first device to determine a data transmission resource required for forwarding data of a second device. By adopting the method, the first equipment can obtain the second control information by descrambling the first control information after receiving the first control information, and finally can determine the data transmission resource required by forwarding the data of the second equipment according to the second control information, so that the scheme of the invention can lead the first equipment to identify the accurate pointing of the control information issued by the network side, and the scrambling mode of the base station by utilizing double identifiers is unchanged, thereby improving the feasibility of the scheme.

and the base station uses the first identifier and the second identifier to carry out scrambling processing on the cyclic redundancy code CRC in the second control information according to the resource request message, and obtains the first control information.

Specifically, after receiving the resource request information sent by the first device, the base station may know whether the resource that the first device needs to request is of the first device itself or the resource that is needed to forward the data of the second device. If it is the resources required to request the data of the first device itself, it is only necessary to scramble the first control with the identity of the first device, i.e. the first identity, and this operation is prior art.

And scrambling the CRC in the second control information by using the first identifier and the second identifier together is a step to be emphasized by the scheme of the present invention, so as to obtain the first control information.

Further, in the embodiment of the present invention, the base station performs scrambling processing on the CRC in the second control information by using the first identifier and the second identifier according to the resource request message, and obtains the first control information. The method for scrambling is specifically described, so that the scheme has stronger practicability in practical application, and the operability of the scheme is improved.

Detailed Description

The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

It should be understood that the present invention is applicable to the scenario of Device-to-Device (abbreviated in english: D2D) communication, and D2D communication refers to a technology for realizing direct communication between close-range user equipments (abbreviated in english: UEs) without the aid of a third party. With the popularization of intelligent terminals, intelligent devices in a network are in an explosive growth stage, and at this time, the industry starts to pay attention to the development of the D2D technology, because the D2D technology in a cellular architecture can help an operator to share heavy network load, unload cellular service, supplement an existing cellular network architecture and bring a new profit income mode, and can improve spectrum efficiency and obtain higher throughput performance and lower transmission delay based on natural advantages of near field communication.

Referring to fig. 2, fig. 2 is a schematic diagram of device-to-device communication with/without network coverage in an embodiment of the present invention, as shown in the left side of fig. 2, a single-hop D2D communication with network coverage is shown, cell users can communicate directly through a D2D link in addition to communicating through a base station service, D2D communication and cell users reuse the same resource, and users performing D2D communication are also controlled by a cell base station. The system base station controls the resources used by the D2D communication and the transmit power of the D2D communication to ensure that the interference that D2D brings to the cell's existing communications is within an acceptable range.

The right side of fig. 2 is a single-hop D2D communication schematic under no network coverage, and in the case of no network coverage (for example, in a disaster scene), the D2D technology can also support direct interaction of information between terminals, so as to avoid complete interruption of local communication caused by network breakdown.

It can be seen that the D2D technology plays a very important role in the future network evolution, and therefore, it has been used as the fifth generation mobile communication technology (english full name: 5)^thGeneration, english abbreviation: 5G) one of the candidate technologies of (2) is widely studied by academia and industry.

The present invention is specifically applied to a Long Term Evolution (Long Term Evolution, english abbreviation: LTE) communication system, please refer to fig. 3, fig. 3 is a schematic diagram of a Long Term Evolution system architecture in an embodiment of the present invention, wherein descriptions of each network element and interface are as follows:

mobility Management Entity (Mobility Management Entity, abbreviated in English: MME)/Serving GateWay (Serving GateWay, abbreviated in English: S-GW): the MME is a key control node in the third Generation Partnership Project (3 rd Generation Partnership Project, 3GPP), and belongs to a core network element, and is mainly responsible for a signaling processing part, i.e., a control plane function, including functions such as access control, mobility management, attach and detach, a session management function, and gateway selection. The S-GW is an important network element of a core network in 3GPP LTE, and is mainly responsible for a user plane function of user data forwarding, that is, routing and forwarding of a data packet are performed under control of the MME.

A base station: the base station in LTE is mainly responsible for radio resource management, Quality of Service (QoS) management, data compression, encryption, and other functions on the air interface side. And towards the core network side, the eNB is mainly responsible for forwarding the control plane signaling to the MME and forwarding the user plane service data to the S-GW.

UE: the UE is a device in LTE that accesses a network side through a base station, and may be a handheld terminal, a notebook computer, or other devices that can access the network.

Interface S1: is the standard interface between the base station and the core network. The base station is connected with the MME through an S1-MME interface and is used for controlling the transmission of signaling, and the base station is connected with the S-GW through an S1-U interface and is used for the transmission of user data. Wherein the S1-MME interface and the S1-U interface are collectively called S1 interface.

X2 interface: and the standard interface between the base stations is used for realizing the intercommunication between the base stations.

A Uu interface: the Uu interface is a radio interface between the UE and the base station, and the UE accesses the LTE network through the Uu interface.

It should be understood that the first device in the embodiment of the present invention is a relay device, and a mobile phone is taken as an example for description, but the first device is not limited to a mobile phone in practical application, and may also be a terminal device such as a tablet computer (Pad), a palmtop computer (PDA), and the like, so that the first device is not limited herein.

It should be understood that the second device in the embodiment of the present invention is a master device, which will be described herein with reference to WD as an example, but in practical applications, the second device may also be a mobile phone terminal device with limited power, a Machine Type Communication (MTC) terminal device, and the like, and therefore, the second device is not limited herein.

The number of WDs will increase dramatically in the future, and it is expected that WDs will perform some basic communication services, such as short message service or voice service. In order to extend the endurance of the WD, the energy consumption of the WD should be reduced as much as possible. As seen from the results of the various party evaluations, the energy consumption of the device for transmission accounts for approximately 80% of the total energy consumption, and it is therefore desirable to reduce the transmission power of the WD to reduce its power consumption. One possibility is that the WD does not need to send data directly to a base station at a greater distance, but rather forms a cooperative group with one or more nearby RDs, since the short-range D2D communication can greatly reduce the transmission power of the WD, and the uplink data of the WD may be sent to the RD by the short-range D2D communication before being forwarded to the network by the RD. It can be seen that the two-hop mode based on D2D has a great advantage in saving WD power consumption.

Referring to fig. 4, fig. 4 is a schematic diagram of a multi-user relay scenario in the embodiment of the present invention, as shown in fig. 4, a relay device 1(RD1), a relay device 2(RD2), and a wearable device 1(WD1) form a device cooperation group1, and RD1 and RD2 serve as a relay device auxiliary WD1 of WD1 to forward uplink data to a network; RD1 and relay device 3(RD3) assist WD2 as a relay device of wearable device 2(WD2) in forwarding its upstream data to the network. It can be seen that the same RD may serve different WDs at the same time, e.g. RD1 belongs to cooperation group1 and cooperation group2 at the same time in the figure, i.e. it serves WD1 and WD2 at the same time. The two cooperating groups each have a respective group identity, which may be some form of group Radio Network Temporary Identity (RNTI).

Referring to fig. 5, an embodiment of a method for controlling information processing according to an embodiment of the present invention includes:

101. the base station uses the first identifier and the second identifier to carry out scrambling processing on the second control information according to the resource request message, and obtains first control information;

In a wireless network communication system, a base station transmits data to a UE through downlink transmission, and the UE generally includes two steps when receiving downlink data: firstly, the UE receives Downlink Control signaling (DCI) in a Physical Downlink Control Channel (PDCCH) or an enhanced Physical Downlink Control Channel (ePDCCH), the DCI instructs the UE to perform a series of actions including instructing the UE how to receive Downlink data, how to transmit uplink data, how to perform transmit power adjustment, and the like, and secondly, after correctly receiving the DCI, the UE receives real Downlink data in a Physical Downlink Shared Channel (PDSCH) according to an instruction received from the DCI. In order to help the UE determine the usage of the received DCI, the DCI in the LTE system is divided into a plurality of DCI formats, and different types of RNTIs are used for parity bit generation. When the UE receives the DCI, the purpose of the DCI can be determined by judging which DCI format and RNTI the received DCI adopts.

102. The base station sends the first control information to the first equipment, so that the first equipment descrambles the first control information by using the first identifier and the second identifier, and obtains second control information;

in this embodiment, after scrambling the second control information by using the first identifier and the second identifier according to the resource request message, the base station may obtain the first control information, and then send the first control information to the first device, so that the first device descrambles the first control information by using the first identifier and the second identifier together after receiving the first control information, and obtains the descrambled second control information.

103. The first device uses the first identifier and the second identifier to perform descrambling processing on the first control information and obtain second control information, wherein the second control information is used for the first device to determine data transmission resources required for forwarding data of the second device.

In this embodiment, the first device performs descrambling processing on the first control information by using the first identifier, and then performs descrambling processing on a result after the first descrambling processing by using the second identifier for a second time, where the second control information is a data transmission resource that is used by the first device to determine to forward data of the second device.

Optionally, on the basis of the embodiment corresponding to fig. 5, in a first optional embodiment of the method for processing control information according to the embodiment of the present invention, from the perspective of the first device, before the first device receives the first control information sent by the base station, the method may further include:

the first device sends a resource request message to the base station, wherein the resource request message is used for requesting the base station by the first device to forward data transmission resources required by data of the second device.

From the perspective of the base station, before the scrambling the second control information by using the first identifier and the second identifier according to the resource request message, the base station may further include:

the base station receives a resource request message sent by the first device, wherein the resource request message is used for the first device to request the base station for transmitting data transmission resources required by the data of the second device.

In this embodiment, first, a first device sends a resource request message to a base station, where the resource request message is mainly used by the first device to request a data transmission resource required for forwarding data of a second device, and then, the base station receives the resource request message sent by the first device and performs subsequent processing on the resource request message, where the subsequent processing is described in steps 101 to 103 in the foregoing embodiment and is not described here again.

The resource request message may specifically be a BSR, where the BSR is mainly used to inform the base station of how much data the UE has to send in an uplink buffer, and provide information of uplink resource scheduling for the base station.

Optionally, on the basis of the embodiment corresponding to fig. 5, in a second optional embodiment of the method for controlling information processing according to the embodiment of the present invention, the first identifier is an identifier of a first device, the second identifier is an identifier of a cooperation group in which the second device is located, and the cooperation group includes one second device and at least one first device.

In this embodiment, it is described that the first identifier is an identifier of the first device, and in this case, when the first device uses the first identifier to perform descrambling processing on the first control information, it may be determined whether the first control information is associated with data of the first device itself. The second identifier is an identifier of a cooperation group in which the second device is located, the cooperation group includes one second device and at least one first device, and the first device can also serve multiple cooperation groups at the same time, however, one cooperation group only has one second device. When the first device fails to descramble the first control information by using the identifier of the first device, descrambling processing may be performed by using the identifier of the cooperation group where the second device is located on the basis of the first control information that has failed to descramble, thereby determining whether the first control information is directed to data of the second device of a certain cooperation group.

Optionally, on the basis of the first or second optional embodiment corresponding to fig. 5 and fig. 5, in a third optional embodiment of the method for processing control information according to the embodiment of the present invention, the performing, by the first device, descrambling processing on the first control information by using the first identifier and the second identifier to obtain the second control information may include:

the first device uses the first identifier to perform descrambling processing on the first control information;

if the descrambling processing of the first control information by using the first identifier fails, the first device acquires third control information, wherein the third control information is the control information obtained after the descrambling processing of the first control information by using the first identifier by the first device;

the first equipment uses the second identifier to perform descrambling processing on the third control information;

and if the third control information is descrambled successfully by using the second identifier, the first device acquires the second control information.

In this embodiment, a first device performs descrambling on first control information by using a first identifier and a second identifier to obtain second control information, specifically referring to fig. 6, fig. 6 is a flowchart illustrating a method for processing control information in an embodiment of the present invention, and as shown in fig. 6, when receiving the first control information, the first device may distinguish the control information by using the flow:

step 201: the first device firstly carries out first-layer descrambling, and descrambles and verifies by using a first Identifier of the first device, namely a Cell Radio Network Temporary Identifier (English full name: Cell Radio Network Temporary Identifier, English abbreviation: C-RNTI);

step 202: the first equipment judges whether descrambling and checking by using the C-RNTI are successful;

step 203: skipping to step 205 if the first device uses the C-RNTI for descrambling and checking successfully, and skipping to step 204 if the first device uses the C-RNTI for descrambling and checking unsuccessfully;

step 204: after the first device fails to use the C-RNTI to descramble and check, the first control information which has been descrambled once is taken as third control information, at the moment, the first device continues descrambling and checking of a second layer, namely, the third control information is descrambled and checked by using a wireless Network temporary identifier (English full name: Group Radio Network temporary identifier, English abbreviation: Group-RNTI) of a cooperative Group;

step 205: after the first device uses the C-RNTI for descrambling and checking successfully, it is determined that the first control information is the data of the first device itself, however, the method for judging the control information through one layer of descrambling is the prior art, so the detailed description is not provided herein;

step 206: if descrambling of the third control information by using the Group-RNTI is successful according to step 204, obtaining the second control information, and determining that the second control information is directed to data of a second device of a certain cooperative Group;

step 207: if descrambling of the third control information using the Group-RNTI according to step 204 fails, the first device determines that the first control information is not assigned to the first device.

Optionally, on the basis of the first or second optional embodiment corresponding to fig. 5 and fig. 5, in a fourth optional embodiment of the method for processing control information according to the embodiment of the present invention, the performing, by the base station, scrambling the second control information by using the first identifier and the second identifier according to the resource request message, and obtaining the first control information may include:

In this embodiment, after receiving the resource request information sent by the first device, the base station may know whether the resource that the first device needs to request is of the first device itself or the resource that is needed to forward the data of the second device. If it is the resources needed to request the data of the first device itself, it is only necessary to scramble the first control with the identity of the first device, i.e. the first identity, and this operation is prior art.

However, for the case that the first device forwards the resource required by the data of the second device, the first identifier and the second identifier are used to scramble the first control information at the same time, and the scrambling of the DCI by using the corresponding RNTI may be specifically embodied in the scrambling of a Cyclic Redundancy Code (CRC) part of the DCI.

CRC is one of the most commonly used error checking codes in the field of data communication, and is characterized in that the lengths of the information field and the check field can be arbitrarily selected.

The basic principle of generating a CRC code is that any code consisting of a binary string of bits can be one-to-one mapped to a polynomial whose coefficients are only "0" and "1". For example: the polynomial corresponding to the code 1010111 is x⁶+x⁴+x²+ x +1, and the polynomial is x⁵+x³+x²+ x +1 corresponds to code 101111.

The CRC check code software is generated by polynomial division with the remainder being the check field, for example: 1011001, the information field code is corresponding to m (x) x⁶+x⁴+x³+ 1; assume the generator polynomial to be: g (x) x⁴+x³+1, the code corresponding to g (x) is 11001; let x be⁴m(x)＝x¹⁰+x⁸+x⁷+x⁴The corresponding code is noted as: 10110010000, obtaining a remainder of 1010 by polynomial division (i.e. the check field is 1010)

10110011010, the receiver checks with the same generator code, i.e. the received field/generator code (binary division) is correct if it can be divided up.

It should be noted that, by using the scheme of the present invention, on the basis of not affecting the original behavior of the RD for receiving the control information, the RD can further distinguish whether the control information is for the WD data for the RD forwarding assistance. The following scheme may also be used to ensure that the RD can correctly associate the control information with the corresponding resource request information on the basis of not changing the RD receiving the control information, specifically:

referring to the schematic diagram of the multi-user relay scenario in fig. 4, please refer to fig. 7, fig. 7 is a schematic diagram of differentiating control information in the embodiment of the present invention, and for the scenario shown in fig. 4, it is assumed that the relay device RD1 sends the BSR0, the BSR1, and the BSR2 to the base station to apply for sending own data and forwarding resources required for WD1 and WD2 data. In order to make the RD accurately distinguish the control information of different purposes, another way is that the base station side and the RD side are well defined, and the base station determines the time sequence for sending the control information to the relay according to the time sequence for receiving the BSR, as shown in fig. 7 specifically:

in fig. 7, the base station side issues corresponding control information to RD1 according to the sequence of receiving BSRs reported by RD1 in the time domain.

It can be understood that, although the scheduling flexibility of the base station side is reduced compared with the embodiment of the present invention, the implementation is simpler, the receiving behavior of the relay device side for the control information does not need to be changed, the RD can be ensured to correctly associate the control information with the corresponding reported information on the basis of not changing the RD receiving control information, and the implementation is simple.

For easy understanding, a detailed description is given below of a method for processing control information according to the present invention in a specific application scenario, please refer to fig. 8, where fig. 8 is a schematic diagram of distinguishing control information in an application scenario, specifically:

assuming that for the multi-user relay scenario shown in fig. 4, if the relay device RD1 sends the BSR0, the BSR1, and the BSR2 to the base station, that is, applies for sending resources required for sending own data and forwarding the WD1 and the WD2 data to the base station, and the relay device RD2 sends the BSR3 to the base station, that is, applies for forwarding the resources required for the WD1 data to the base station, the RD can accurately distinguish control information of different purposes by using the method shown in fig. 8.

In fig. 8, the base station jointly scrambles DCI0_1 by using Group identity Group1-RNTI of Group1 where RD1 and WD1 are located and identity RD1-C-RNTI of RD1 itself, where DCI0_1 is control information used by the base station to indicate to RD1 to forward WD1 data, and the base station uses Group identity Group2-RNTI of Group2 where RD1 and WD2 are located and identity RD 1-C-jointly scrambles DCI0_2 of RD1 itself, where 0_2 is control information used by the base station to indicate to DCI 1 to forward WD2 data. The base station scrambles DCI0_3 jointly by using Group identification Group1-RNTI of a cooperative Group1 in which RD2 and WD1 are located and identification RD2-C-RNTI of RD2, wherein the DCI0_3 is control information related to the base station and used for indicating to the RD2 to forward WD1 data, the base station scrambles DCI0_0 by using identification RD1-C-RNTI of RD1, and the DCI0_0 is control information related to the base station and used for indicating to the RD1 to send RD1 data.

Scrambling the DCI using the corresponding RNTI may embody scrambling of the CRC portion in the DCI. For example, the CRC redundancy check bits of the four DCIs (DCI0_0, DCI0_1, DCI0_2, and DCI0_3) are respectively:

CRC redundancy check bits before DCI0_0 scrambling:

CRC redundancy check bits before DCI0_1 scrambling:

CRC redundancy check bits before DCI0_2 scrambling:

CRC redundancy check bits before DCI0_3 scrambling:

through the scrambling of fig. 8, the CRC redundancy check bits after each DCI scrambling are as follows:

CRC redundancy check bits after DCI0_0 scrambling:

CRC redundancy check bits after DCI0_1 scrambling:

CRC redundancy check bits after DCI0_2 scrambling:

CRC redundancy check bits after DCI0_3 scrambling:

for all k e [0, …,15]，

Wherein,andthe bit values are corresponding to the kth bit in the bit sequence of RD1-C-RNTI, RD2-C-RNTI, Group1-RNTI and Group2-RNTI in FIG. 8. When the base station side scrambles the control information in the above manner, the relay device may distinguish the control information by using the following procedures when receiving the control information:

the first step is as follows: the RD descrambles and verifies by using the C-RNTI of the RD;

the second step is that: if the RD uses the self C-RNTI to descramble and verify successfully, the control information is determined to be the data of the RD, if the RD uses the self C-RNTI to descramble and verify unsuccessfully, the second layer of descrambling is carried out, and the Group-RNTI of the cooperation Group where the RD is located is used for descrambling and verifying on the basis of the first layer of descrambling;

the third step: and if the second layer descrambling check is successful, determining that the control information is directed to the WD data of a certain cooperation group, and if the second layer descrambling check is failed, determining that the control information is not distributed to the RD.
