Description

Communication resource allocation instruction method, system and device thereof

technical field

The present invention relates to mobile communication physical layer technology, in particular to a technology for indicating allocation of physical resource blocks.

Background technique

At present, the Evolved Universal Terrestrial Radio Access (E-UTRA, Evolved Universal Terrestrial Radio Access) system proposed by the Third Generation Partnership Project (3GPP, Third Generation Partnership Project) uses Orthogonal Frequency Division Multiplexing (OFDM) in downlink transmission. , Orthogonal Frequency Division multiplexing) technology. OFDM is a multi-carrier communication technology that realizes multi-user multiplexing by allocating different physical resources for different users. The downlink transmission of the E-UTRA system can be further divided into Localized Transmission and Distributed Transmission. The transmission bandwidth of the E-UTRA system is evenly divided into multiple physical resource blocks (PRB, Physical Resource Block) composed of continuous subcarriers, and the physical resources occupied by centralized transmission and decentralized transmission are based on PRB as the basic unit. The PRB used for localized transmission is called L-PRB (Localized-PRB), and the PRB used for distributed transmission is called D-PRB (Distributed-PRB). The base station allocates one or more L-PRBs with better channel conditions for each centralized transmission user (L-UE, L-User) to achieve multi-user diversity; the base station assigns each decentralized transmission user (D-UE, D-User) allocates a certain number of subcarriers uniformly distributed in all D-PRBs to achieve frequency diversity.

After the base station scheduler allocates resources for each centralized transmission user and distributed transmission user to be scheduled, it sends control information through the physical layer shared control channel to inform the scheduling user of the resource allocation of centralized transmission and decentralized transmission, including the scheduled User identification (UE-ID) and resource allocation indication signaling. When the user receives the control information, he first determines whether he is scheduled, that is, whether the control information contains his UE-ID; if he is scheduled, the user confirms the location of the physical resource allocated by the base station through the resource allocation instruction signaling. The control information also includes other control information related to data transmission. The encoding methods of user control information are divided into independent encoding and joint encoding. Generating a coding block from control information of each user by the base station is called independent coding, and generating a coding block from control information of multiple users by the base station is called joint coding. Since there is a correlation among the resources allocated to each user, the joint coding can realize the joint indication of resource allocation for multiple users, and effectively reduce the signaling amount of the resource allocation indication signaling. For independent coding, the control information of each user is coded independently, and the resource allocation can only be indicated independently. Therefore, compared with joint coding, more signaling is required to complete the resource allocation indication for all scheduled users.

In the prior art, a hybrid coded transmission method of control information, multiple scheduling user resource allocation indication signaling and UE-ID and other signaling related to resource allocation (such as allocation duration) are jointly encoded and sent as common information , other control information of each user is coded separately and transmitted in its own control channel. All users demodulate the control information of the joint coding part, and confirm whether they are scheduled through the UE-ID information in the joint coding. If a user is scheduled, the scheduled user confirms the resource according to the resource allocation indication signaling of the joint coding Allocation and demodulation of control signaling belonging to its own independent coded part.

Assuming that the current scheduled users are UE_1, UE_2, UE_3 and UE_4, all of which are centralized transmission users, the channel resource allocation of the scheduled users is shown in FIG. 1 . The base station performs joint encoding on the resource allocation instruction signaling of the scheduled user and the UE-ID to generate control signaling and sends it to all users to inform the users of the resource allocation situation. The public information generation process includes:

The UE-IDs of all scheduled users are sorted, each UE-ID corresponds to a sequence number, and each sequence number is represented by a binary number. For example, if the transmission sequence of UE-ID is defined as {UE_1 UE_2 UE_3 UE_4}, the sequence number corresponding to each UE-ID is {00 01 10 11}.

A corresponding sequence is then generated according to the resource allocation situation of each scheduling user and the sequence number of the scheduling user corresponding to each PRB. For example, in Figure 1, scheduling user UE_1 occupies the first and second PRBs, scheduling user UE_2 occupies the third, fourth, fifth, seventh, and eighth PRBs, scheduling user UE_3 occupies the sixth PRB, and scheduling user UE_4 The ninth to twelfth PRBs are occupied, and the generated sequence is {00 00 01 01 01 10 01 01 11 11 11 11} according to the serial number of each user. The sequence is the required resource allocation indication signaling.

Finally, the UE-ID of the scheduling user and the resource allocation indication signaling are combined to form public information and sent to the user.

Although the above technical solution can realize the joint indication of resource allocation for multiple users, the public information also includes UE-ID, which causes more signaling overhead; and the length of the public information changes with the number of scheduled users. If Allocating the length of public information according to the maximum possible number of scheduling users will cause waste of resources when the number of scheduling users is small. If the length of public information is allocated according to the actual signaling amount, in order to ensure that users can demodulate the public information , additional information needs to be transmitted to indicate the length of the public information, or multiple blind checks are required to determine the length of the public information, which will increase the complexity of parsing the public information for users.

Detailed ways

The invention provides a resource allocation instruction method and system thereof. In order to make the present invention more clear, the present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings.

Please refer to FIG. 2 , which is a structural diagram of a preferred embodiment of the resource allocation indication system of the present invention. The resource allocation instruction system includes a sending device 10 and a receiving device 20, the sending device 10 may exist in a base station of a communication network, and the receiving device 20 may exist in a user terminal. The sending device 10 includes a resource allocation unit 11 , a resource allocation indication signaling generation unit 12 , an independent control signaling generation unit 13 and a physical resource mapping unit 14 . Wherein, the resource allocation unit 11 is configured to allocate resources to centralized transmission users and distributed transmission users. The resource allocation instruction signaling generation unit 12 generates jointly coded common information according to the resource allocation situation determined by the resource allocation unit 11 . The independent control signaling generation unit 13 generates independently coded control signaling according to the data transmission mode of the scheduled user, and scrambles the UE-ID into the control signaling for transmission. The physical resource mapping unit 14 is configured to map the common information generated by the resource allocation instruction signaling generation unit 12 and the independently coded control signaling generated by the independent control signaling generation unit 13 onto pre-designated shared control channel physical resources for transmission. The receiving device 20 includes a physical resource demapping unit 21 and a resource allocation indication signaling analysis unit 22 . Wherein, the physical resource demapping unit 21 is configured to obtain jointly coded common information and independently coded control signaling sent by the sending device 10 from the physical resource corresponding to the control channel in the received signal. The resource allocation indication signaling analysis unit 22 is configured to analyze the resource allocation indication signaling and the control signaling, so as to confirm whether the user is scheduled, and determine the resource position allocated to the user.

Please refer to FIG. 3 , which is a flow chart of a preferred embodiment of the resource allocation indication method provided by the present invention. In this embodiment, all resource allocation indication signaling is sent to all users as public information. The resource allocation indication method involved in this embodiment specifically includes the following steps:

Step 101: Allocate PRBs to scheduling users, including centralized transmission users and decentralized transmission users, that is, divide the system broadband into multiple PRBs, and allocate a certain number of PRBs to each scheduling user, among which L-PRBs are allocated to centralized transmission users and distributed transmission users Users allocate D-PRBs.

Step 102: Generate public information through joint coding according to the allocation of PRBs for centralized transmission users and distributed transmission users. The public information includes all resource allocation indication signaling for centralized transmission users and all resource allocation indication signaling for distributed transmission users.

For centralized transmission users, the list method can be used to generate all resource allocation indication signaling: the scheduled centralized transmission users are sorted, and a sequence number is generated for each centralized transmission user. The sequence number is represented by a binary number, and then corresponds to the scheduled The PRB allocation of the centralized transmission user generates a sequence, and the sequence is all resource allocation indication signaling of the centralized transmission user.

For distributed transmission users, since distributed transmission users allocate one or more consecutive D-VRBs to each distributed transmission user in sequence when performing resource allocation, the distributed transmission user resource allocation instruction signaling only needs to give each The number of D-VRBs allocated by the user can be distributed and transmitted.

Step 103: According to the data transmission mode of each scheduled user, generate corresponding independent coding-based control signaling, and scramble the UE-ID of the scheduled user into the control signaling.

For example, the control signaling based on independent encoding is encoded and rate-matched to generate sequences r _1,1 , r _1,2 ... r _1,40 , and the UE-ID information of the scheduled user is encoded to generate sequences c ₁ , c ₂ , . . . c ₄₀ . Then scramble the sequence generated by the UE-ID to the sequence generated by the control signaling to obtain the control signaling based on independent coding that is finally transmitted to the scheduling user, that is, the sequence s _1,1 , s _1,2 ... s _1,40 . The scrambling process is:

s _{1, k} = (r _{1, k} + c _k ) mod2 k = 1, 2...40

Or, the same method is used to scramble the UE-ID information of the scheduling user to the CRC check bit of the control signaling coding block.

Step 104: Map the generated public information and the control signaling based on the independent coding to the shared control channel for transmission.

Step 105: The user receives the common information transmitted by the shared control channel and the control signaling based on independent coding.

Step 106: The user detects the control signaling based on independent encoding in sequence, and checks whether it is scheduled, and if it is scheduled, determines the location of the allocated physical resource according to the resource allocation indication signaling in the public information and the independently encoded control signaling .

Wherein step 102 and step 103 can be performed at the same time, or step 103 can be performed first and then step 102 can be performed.

Please refer to FIG. 4 , which is a flow chart of another preferred embodiment of the resource allocation indication method provided by the present invention. In this embodiment, a part of the resource allocation indication signaling is sent to all users as public information, and another part of the resource allocation indication signaling is sent to corresponding users through independently coded control signaling. The resource allocation indication method involved in this embodiment specifically includes the following steps:

Step 201: Allocate resources for scheduling users, including centralized transmission users and distributed transmission users, that is, divide the system broadband into multiple PRBs, and allocate a certain number of PRBs for each scheduling user: allocate L-PRBs for centralized transmission users, and allocate L-PRBs for distributed transmission users. Users allocate D-PRBs.

Step 202: Generate jointly coded public information according to the allocation of PRBs for centralized transmission users and decentralized transmission users. The public information includes primary resource allocation indication signaling. The length of the public information is fixed. The following methods can be used for resource allocation indication:

Use two bits of information to indicate the four states of the PRB: for example, use 00 to indicate that the PRB and the previous continuous PRB belong to the same type. If the previous PRB is an L-PRB, it not only means that the PRB and the previous PRB are both L-PRB, It further indicates that the PRB and the previous PRB are allocated to the same user; use 01 to indicate that the PRB is L-PRB, and does not belong to the same user as all previous L-PRBs; use 10 to indicate that the PRB is D-PRB; use 11 indicates that the PRB is an L-PRB, and is allocated to the same user as one or several previous L-PRBs, but this PRB is not continuous with these L-PRBs. The multiple L-PRBs allocated to the same user include the initial continuous L-PRB part represented by 00 and the discontinuous continuous L-PRB part represented by 11. If the system bandwidth is divided into N PRBs, 2×N information bits can be used to indicate the status of each PRB and a part of resource allocation.

Step 203: According to the primary resource allocation indication signaling in the public information, generate the secondary resource allocation indication signaling in the control signaling independently coded by each scheduling user, and indicate the resource allocation of the scheduling user together with the public information.

For centralized transmission users, since the respective control channels of the users are mapped on the physical resources in sequence, the position of the control channel detected by the user is consistent with the sequence of the initial continuous L-PRB part. It can determine the initial continuous L-PRB part belonging to itself, so there is no need to indicate how to allocate the initial continuous L-PRB part to the user in the public information. Therefore, the sub-resource allocation indication signaling only needs to include the number of L-PRB parts that the user discontinuously continues.

For distributed transmission users, the base station allocates one or more continuous distributed-virtual resource blocks (D-VRB, Distributed-Virtual Resource Block) to each distributed transmission user in sequence, and maps the data to the allocated D-VRB corresponding transmission on the D-PRB. Since the primary resource allocation indication signaling in the public information indicates the positions of all D-PRBs, the secondary resource allocation indication signaling only needs to indicate how D-VRBs are allocated to users. The indication method of "start+length" can be adopted, for example, binary numbers are used to represent the start sequence number of the D-VRB allocated to each user and the number of consecutive allocations.

Step 204: Scramble the UE-ID of the scheduled user into the independently coded control signaling. The specific scrambling process is the same as that in the first preferred embodiment, and no further description is given here.

Step 205: Map the generated public information and the control signaling based on independent coding to a pre-designated shared control channel for transmission.

Step 206: All users receive common information transmitted on the shared control channel and scheduled users receive control signaling based on independent coding.

Step 207: The user detects the control signaling based on independent encoding in order to check whether it is scheduled, and if it is scheduled, according to the resource allocation indication signaling in the public information and the secondary resource allocation indication signal in the independently encoded control signaling command to determine the assigned physical resource location.

In order to further illustrate the resource allocation indication method of the present invention, an example will be described below.

Please refer to Figure 5 for an example diagram of user resource allocation. In Fig. 5, the system bandwidth of 5 MHz is divided into 12 PRBs, including 8 L-PRBs and 4 D-PRBs. The scheduled users include four concentrated transmission users named L-UE_1, L-UE_2, L-UE_3, and L-UE_4, and three distributed transmission users named D-UE_1, D-UE_2, and D-UE_3. The allocation of user resources for centralized transmission is as follows: the 0th and 1st PRBs are allocated to the initial continuous L-PRB part of user L-UE_1, the fourth PRB is allocated to the intermittent continuous L-PRB part of user L-UE_1, and the 3rd PRB The 10th PRB is allocated to user L-UE_2, the 7th and 8th are allocated to the initial continuous L-PRB part of user L-UE_3, the 10th PRB is allocated to the intermittent continuous L-PRB part of user L-UE_3, and the 9th PRBs are allocated to user L-UE_4. The distribution of distributed transmission user resources is as follows: the 0th and 1st D-VRB are allocated to user D-UE_1, the second D-VRB is allocated to user D-UE_2, and the third D-VRB is allocated to user D-UE_3 .

If a method of using a part of the resource allocation indication signaling as public information and another part of the resource allocation indication signaling as independently coded control signaling indicates user resource allocation. The resource allocation indication signaling in public information and the resource allocation indication signaling in independent coding-based control signaling are as follows:

The resource allocation indication signaling in the public information is {01 00 10 01 11 10 00 01 11 10}, where 00 indicates that the PRB and the previous continuous PRB belong to the same type. If the previous PRB is an L-PRB, it not only indicates that the PRB Both the previous PRB and the previous PRB are L-PRB, and further indicate that the PRB and the previous PRB are allocated to the same user; use 01 to indicate that the PRB is an L-PRB, and it does not belong to the same user as all the previous L-PRBs; Use 10 to indicate that the PRB is a D-PRB; use 11 to indicate that the PRB is an L-PRB, which is allocated to the same user as one or several previous L-PRBs, but the PRB is not continuous with these L-PRBs.

For each centralized transmission user, the resource allocation indication signaling in the control signaling based on independent coding is: L-UE_1[10], L-UE_2[00], L-UE_3[01], L-UE-4 [00]. Since there are 2

A discontinuous and continuous L-PRB needs to indicate which user is allocated to, so 2 bits are used for indication, 1 indicates that it is allocated to this user, and 0 indicates that it is not allocated to this user.

For each distributed transmission user, the resource allocation indication signaling in the independent coding-based control signaling is respectively: D-UE_1 [0010], D-UE_2 [1001], D-UE_3 [1101]. Since there are 4 D-VRBs, 2 bits are used to indicate the serial number of the starting D-VRB occupied by the user, and the other 2 bits are used to indicate the number of consecutive D-VRBs occupied by the user.

In addition, in order to ensure that all users can correctly receive the public information, a relatively high transmission power or a relatively low channel coding rate may be used for the public information. The method provided by the present invention can separately determine resource allocation indication signaling for uplink scheduling and downlink scheduling, and the two parts of information can be combined together as unified public information and sent.

Moreover, when the control information other than the resource allocation indication needs to be received and demodulated by multiple users, for example, when multi-antenna multi-codeword transmission is performed, the number of data streams for each user indicates information, and this part of information can be related to The jointly coded resource allocation indication signaling is sent together as common information. If the signaling length of the independently coded control signaling is variable, its length indication signaling can also be sent in common information together with the resource allocation indication signaling.

The resource allocation instruction method and system provided by the present invention have been described above in detail. In this paper, specific examples are used to illustrate the principle and implementation of the present invention. The description of the above embodiments is only used to help understand the present invention. method and its core idea; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope.
