It should be noted that the specific functions of the user terminal 11 and the base station 12 are described in detail through a plurality of embodiments below.

Referring to fig. 2, fig. 2 is a flowchart of a method for sending a DCI format message according to an embodiment of the present invention, as shown in fig. 2, including the following steps:

step 201, generating a DCI format message.

In this step, a corresponding DCI format message may be generated according to data transmission required by the base station and the user terminal.

Step 202, sending the DCI format message to a user equipment, and indicating a sequence number of a bandwidth fragment (bandwidth part) for data transmission through implicit resources related to the DCI format message.

The implicit resource related to the DCI format message may be a transmission resource occupied by the DCI format message, or may be resource information included in the DCI format message, for example: an information check field of a cyclic redundancy check code of the DCI format message, or a redundancy version of the DCI format message, and the like. By the implicit resource indication, the serial number of the bandwidth fragment used for data transmission can be transmitted without adding extra information in the DCI format message, thereby saving the cost of the DCI format message and achieving the purpose of reducing the cost of a downlink control link of a broadband user terminal.

It should be noted that, in this embodiment, the method described above may be applied to the base station shown in fig. 1. In addition, the present invention can be applied to a 5G System, and can also be applied to an application scenario in which a Global System for Mobile Communication (GSM) and a multi-carrier are applied to a Code Division Multiple Access (CDMA) technology, and in the application scenario, different ues can have different bandwidth transmission capabilities and overhead of DCI format messages can be reduced.

In this embodiment, a DCI format message is generated; and sending the DCI format message to a user terminal, and indicating the sequence number of the bandwidth fragment for data transmission through implicit resources related to the DCI format message. Since the implicit resource related to the DCI format message indicates the sequence number of the bandwidth segment used for data transmission, the overhead of the DCI format message can be reduced.

Referring to fig. 3, fig. 3 is a flowchart of another sending method for a DCI format message according to an embodiment of the present invention, as shown in fig. 3, including the following steps:

and step 301, generating a DCI format message.

Optionally, the DCI format message may include sequence numbers of Resource Blocks (RBs) or Resource Block groups (RB groups) used for data transmission in the bandwidth segment for data transmission, so that the RBs used for data transmission may be accurately indicated to the user terminal through the sequence numbers of the RBs or the RB groups, so as to improve communication performance of the base station and the user terminal.

Step 302, sending the DCI format message to a user equipment, and indicating a sequence number of a bandwidth segment for data transmission through implicit resources related to the DCI format message.

Resources within one carrier (Pcell or Scell) may be partitioned into a number of different bandwidth segments, for example: m bandwidth segments, a base station can transmit and receive data in multiple bandwidth segments. Here by m_BandpartTo indicate the serial number of the bandwidth segment, then 0 ≦ m_BandpartLess than or equal to M-1. The bandwidth segment for data transmission may be a base stationBandwidth segments that need to transmit data, such as: downlink transmission or uplink reception. That is, when the base station needs to transmit data in a certain bandwidth segment, a corresponding DCI format message is sent to the user equipment to indicate the sequence number of the bandwidth segment.

Optionally, the implicit resource related to the DCI format message includes a Control Channel Element (CCE) occupied by the DCI format message.

In this embodiment, the number of the bandwidth segment can be implicitly indicated by the CCE occupied by the DCI format message, so as to save the overhead of the DCI format message.

Optionally, before generating the DCI format message, the method further includes:

configuring a control channel resource set, the control channel resource set comprising at least two CCEs;

and sending the configuration parameters of the control channel resource set to the user terminal.

In this embodiment, Physical Downlink Control Channels (PDCCHs) of one or more user terminals may be configured in the same Control Channel resource set to be transmitted.

In addition, one control channel resource set is divided into a plurality of CCEs, so that a plurality of PDCCHs can be transmitted in one control channel resource set. The CCE may be a basic unit for PDCCH transmission, and the DCI format message of each PDCCH occupies one or more CCEs. Each CCE may include 6 Resource Element Groups (REGs), and each REG may occupy one Orthogonal Frequency Division Multiplexing (OFDM) symbol in a time domain and one RB in a Frequency domain. In addition, since one control channel resource set may include a plurality of CCEs, a sequence number may be arranged for each CCE, and if the control channel resource set includes N CCEs, the sequence numbers of the CCEs are CCE _0 to CCE _ N-1, as shown in fig. 4.

The configuration parameter may be configured through Radio Resource Control (RRC) signaling or other signaling. And the configuration parameter may be a time domain parameter and/or a frequency domain parameter of the control channel resource set. The user terminal can accurately detect the corresponding DCI format message in the control channel resource set through the configuration parameters, and determine the sequence number of the corresponding bandwidth fragment.

Optionally, the configuration parameter includes at least one of:

symbol information of the control channel resource set and frequency resource information of the control channel resource set.

The symbol information may represent OFDM symbols occupied by the control channel resource set in one subframe or slot (slot), and the frequency resource information may represent frequency resources used by the control channel resource set, for example: which RBs are specifically used. For example: the above configuration parameters may be as shown in table 1.

TABLE 1 information field for control channel resource set configuration

In this embodiment, the energy consumption of the ue for detecting the DCI format message may be reduced by the symbol information and the frequency resource information, because the ue only needs to detect a specific symbol and a corresponding RB according to the symbol information and the frequency resource information.

Optionally, the indicating, by using implicit resources related to the DCI format message, a sequence number of a bandwidth segment used for data transmission includes:

and indicating the sequence number of the bandwidth segment by the sequence number of at least one CCE occupied by the DCI format message in the control channel resource set.

In this embodiment, the DCI format message may be transmitted on at least one CCE, but only the sequence number of one CCE is required to indicate the sequence number of the bandwidth segment, so that the complexity of the system may be reduced, and the power consumption of the user terminal may be reduced.

Optionally, the indicating, by the sequence number of at least one CCE occupied by the DCI format message in the control channel resource set, the sequence number of the bandwidth segment includes:

and indicating the sequence number of the bandwidth segment by the sequence number of the first CCE in at least one CCE occupied by the DCI format message in the control channel resource set.

The first CCE may be a CCE ranked first in the order of the time domain or may be a CCE ranked first in the order of the frequency domain.

In this embodiment, the sequence number of the bandwidth segment can be indicated by using the sequence number of the first CCE in all CCEs occupied by the PDCCH for sending the DCI format, so that the user terminal can determine the sequence number of the bandwidth segment in time, thereby improving the working efficiency of the user terminal. Of course, in the embodiment of the present invention, the sequence number of the bandwidth segment is indicated by the first CCE, for example: it is also possible to indicate the sequence number of the bandwidth segment by the last-ranked CCE or the middle CCE, and so on.

and indicating the sequence number of the bandwidth segment used for data transmission by an operation result obtained by modulo the M by the sequence number of at least one CCE occupied by the DCI format message in the control channel resource set, wherein the M is the number of the bandwidth segments included in the carrier bandwidth.

The CCE may be a CCE used to indicate a bandwidth segment sequence number in CCEs occupied by DCI format, for example: the first CCE. For example: by n_CCETo indicate the sequence number of the first CCE (0 ≦ n) of all CCEs occupied by PDCCH transmitting DCI format message_CCEN-1) or less, the sequence number of the bandwidth segment used for data transmission indicated by the DCI format message is

m_Bandpart＝mod(n_CCE,M)

I.e. n_CCEAnd the operation result obtained by taking the modulus of M is the serial number of the bandwidth segment. Therefore, the user terminal can simply, quickly and accurately determine the sequence number of the bandwidth segment through the sequence number of the CCE.Of course, the embodiment of the present invention is not limited thereto, and for example: the base station may also send the DCI format message in the corresponding CCE according to a pre-obtained correspondence between the sequence number of the CCE and the sequence number of the bandwidth segment, and the user terminal determines the sequence number of the bandwidth segment according to the correspondence.

Optionally, the implicit resource related to the DCI format message includes an information check field of a Cyclic Redundancy Check (CRC) Code of the DCI format message.

In this embodiment, the indication of the sequence number of the bandwidth segment by the mask of the cyclic redundancy check code of the DCI format message may be implemented, so that the overhead of the DCI format message may be reduced.

Optionally, the generating the DCI format message includes:

and sending an information check field of the cyclic redundancy check code to the user terminal, and indicating the sequence number of the bandwidth segment for data transmission through the information check field.

The crc of the DCI format message may be a binary sequence with a length L. And the cyclic redundancy check code may be a cyclic redundancy check code of the data information of the DCI format message.

The mask sequence value corresponding to the sequence number of the bandwidth segment may be a mask sequence value having a corresponding relationship with the sequence number of the bandwidth segment, that is, the sequence number of the bandwidth segment may be determined by the mask sequence value. The information check field for generating the cyclic redundancy check code according to the cyclic redundancy check code and the mask sequence value corresponding to the sequence number of the bandwidth segment may be generated according to a mapping relationship among the cyclic redundancy check code, the mask sequence value and the information check field, or may be calculated on the cyclic redundancy check code and the mask sequence value to obtain the information check field of the cyclic redundancy check code.

In this embodiment, the information check field of the cyclic redundancy check code may be sent to the user terminal to indicate the sequence number of the bandwidth segment, so as to achieve the effect of saving the overhead of the DCI format message.

Optionally, the generating an information check field of the cyclic redundancy check code according to the cyclic redundancy check code and a mask sequence value corresponding to the sequence number of the bandwidth segment includes:

and calculating the cyclic redundancy check code and the mask sequence value to obtain an information check field of the cyclic redundancy check code.

The operation of the crc and the mask sequence value may be an or, not, or and operation according to binary bits to obtain an information check field of the crc.

Optionally, the cyclic redundancy check code, the mask sequence value, and the information check field of the cyclic redundancy check code are all binary numbers with a length of L, where L is an integer greater than or equal to 1;

and adding the kth bit data of the cyclic redundancy check code and the kth bit data of the mask sequence value, taking a modulo operation result of the added operation result to 2, and taking the operation result obtained by the modulo operation as the kth bit data of an information check field of the cyclic redundancy check code, wherein k is an integer equal to or less than L.

In this embodiment, the kth bit of the information check field of the crc code may be understood as any one bit of the information check field of the crc code, that is, the kth bit of the information check field of the crc codek is 0, 1, … L-1. For example: before the DCI format message is sent, a cyclic redundancy check code may be added after data information of the DCI format message, where the data information in the DCI format message uses binary data a₀,a₁,a₂,a₃,...,a_A-1To indicate (A is the length of the data information) that the cyclic redundancy check code is p₀,p₁,p₂,p₃,...,p_L-1To represent (L is the length of the parity bit), m_BandpartThe value of (i.e. the MASK sequence value corresponding to the sequence number of the bandwidth segment) is represented by a binary MASK (MASK) sequence with the same length as the information checked by the cyclic redundancy check code, i.e. x_SSI ^_, ₀,x_SSI,1,...,x_SSI,_L-1. A MASK (MASK) sequence value may be added to the final transmission information of the dcifomat message by:

c_k＝a_k for k＝0,1,2,…,A-1

c_k＝(p_k-A+x_SSI,k-A)mod 2 for k＝A,A+1,A+2,...,A+15.

wherein, c₀,c₁,c₂,c₃,...,c_K-1Final transmission information indicating DCI format message, c_k＝a_kAs data information, c_k＝(p_k-A+x_SSI,k-A) mod2 is the information check field of the crc generated by the crc and the mask sequence value, and K is a + L, so that the DCI format message may include the data information (DCI format), the mask sequence value corresponding to the sequence number of the bandwidth segment, and the crc. Therefore, the serial number of the bandwidth segment is indicated by using the implicit resource, and the transmission overhead of the system is saved. After the user terminal receives the information check field of the cyclic redundancy check code, the information check field of the cyclic redundancy check code may be checked to determine the sequence number of the bandwidth segment.

Optionally, in order to maximize the distance between the sequence numbers of the bandwidth segments to achieve the best transmission effect of the sequence numbers of the bandwidth segments, the mask corresponding to the sequence numbers of the bandwidth segmentsThe code sequence value is the sequence number and 2 of the bandwidth segment^L-JThe number of the values of the sequence number of the bandwidth segment is 2^JWherein J is an integer.

For example: mask sequence value x corresponding to sequence number of bandwidth segment_SSI,0,x_SSI,1,...,x_SSI,L-1A length L, and a value range of 0 to 2^L-1, the number M of values of the sequence numbers of the bandwidth segments being 2^JI.e. can identify 2^JA different bandwidth segment. M is more than or equal to 0_Bandpart≤2^JX for-1_SSI,0,x_SSI,1,...,x_SSI,L-1The sequence value is:

m_Bandpart×2^L/M＝m_Bandpart×2^L-J

further, if the number of the values of the sequence numbers of the bandwidth segments is not large, optimization can be performed at the codeword level. Optionally, in the mask sequence values corresponding to the sequence numbers of the adjacent bandwidth segments, the number of bits with different values is greater than or equal to L/2. For example: l16, the value that the mask sequence value can represent is 2^LAll possible values are only 9, from 2^LThe useful mask sequence value is selected from 9 values, thereby further improving the transmission effect of the sequence number of the bandwidth segment. For example: taking L-16 as an example, the correspondence between the sequence number of the bandwidth segment and the mask sequence value is shown in table 1.

Table 1: correspondence table between time sequence number and mask sequence value
