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.
Referring to fig. 1, fig. 1 is a structural diagram of a DCI format message transmission system applicable to the embodiment of the present invention, and as shown in fig. 1, the DCI format message transmission system includes a user terminal 11 and a base station 12, where the user terminal 11 may be a ue (user equipment), for example: the terminal side Device may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and it should be noted that the specific type of the user terminal 11 is not limited in the embodiments of the present invention. The base station 12 may be a 5G base station (e.g., a gNB, a 5G NR NB), or may be a 4G base station (e.g., an eNB), or may be a 3G base station (e.g., an NB), and the like, and it should be noted that a specific type of the base station 12 is not limited in this embodiment of the present invention.
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:
In this step, a corresponding DCI format message may be generated according to data transmission required by the base station and the user terminal.
The control channel resource corresponding to the bandwidth segment may be a control channel resource configured in advance by the base station, or may be a control channel resource agreed in advance by the base station and the user terminal, or may be a control channel resource defined in a protocol, and the like.
In this embodiment, since the DCI format message is sent in the control channel resource corresponding to the bandwidth segment for data transmission, the order of the corresponding sequence number of the bandwidth segment is indicated by the control channel resource. The user terminal may determine the bandwidth segment for data transmission through the control channel resource, for example: and determining according to the corresponding relation between the control channel resources and the bandwidth fragments, so that the DCI format message does not need to include the serial numbers of the bandwidth fragments, and the overhead of the DCI format message is reduced.
It should be noted that, in the implementation of the present invention, the above method can 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 user terminals may have different bandwidth transmission capabilities, and the overhead of DCI format messages may be reduced, so as to achieve the purpose of reducing the control overhead in bandwidth scheduling.
In the embodiment of the invention, a DCI format message is generated; and sending the DCI format message to a user terminal on a control channel resource corresponding to the bandwidth fragment for data transmission. Therefore, the user terminal can determine the bandwidth fragment for data transmission through the control channel resource, thereby reducing the overhead of the DCI format message.
Referring to fig. 3, fig. 3 is a flowchart of a method for sending 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.
In this step, a corresponding DCI format message may be generated according to data transmission required by the base station and the user terminal.
Optionally, the DCI format message may include a sequence number of an RB used for data transmission in the bandwidth segment, so that the RB used for data transmission may be accurately indicated to the user terminal through the sequence number of the RB, so as to improve communication performance of the base station and the user terminal.
The bandwidth segment for data transmission may be a bandwidth segment that a base station needs to transmit data, for example: downlink transmission or uplink reception. That is, when the base station needs to transmit data on a certain bandwidth segment, the DCI format message is sent on the corresponding control channel resource set, so as to achieve the effect of indicating the sequence number of the corresponding bandwidth segment according to different control channel resource sets.
Optionally, the control channel resource may be a set of control channel resources, that is, the control channel resource may be a set of resources. The set of control channel resources may include one or more RBs occupying one or more Orthogonal Frequency Division Multiplexing (OFDM) symbols.
Optionally, before the DCI format message is sent to the user terminal by using the control channel resource corresponding to the bandwidth segment for data transmission, the method further includes:
and sending the configuration parameters of the control channel resources to the user terminal.
The configuration parameter may be a resource configuration parameter of the control channel resource, for example: the control channel resources can be accurately indicated to the user terminal through the configuration parameters, and the user terminal can accurately perform blind detection on the DCI format messages on the control channel resources, so that the blind detection performance of the user terminal is improved. Of course, in this embodiment, the base station may send configuration parameters of multiple or all control channel resources to the user terminal, so that the user terminal performs blind detection on the multiple or all control channel resources based on the configuration parameters, so as to accurately receive the DCI format message sent by the base station. In addition, the configuration parameter may be configured through Radio Resource Control (RRC) signaling, but the embodiment of the present invention is not limited to this, for example: it may also be configured through other higher layer signaling.
Optionally, the configuration parameter includes at least one of:
the serial number of the control channel resource, OFDM symbol information, frequency resource information and subframe information.
For example: taking the control channel resource set as an example, as shown in table 1:
TABLE 1 information field for control channel resource set configuration
The sequence number of the control channel resource may indicate a sequence number in a plurality of control channel resource sets configured by the base station, so as to distinguish different control channel resource sets and sequence numbers for each control channel resource set.
Optionally, the OFDM symbol information is used to indicate OFDM symbols occupied by the control channel resources in a subframe or slot. The OFDM symbols occupied by the control channel resources can be accurately indicated through the OFDM symbol information. In addition, since the user terminal needs to detect the control channel before detecting the data channel, the OFDM symbols occupied by the control channel resources generally occupy the first several OFDM symbols of one subframe or slot. And if more control information is needed, the control channel resources may occupy all OFDM symbols of one subframe or slot. Preferably, taking the set of control channel resources as an example, the OFDM symbol information may use 2 bits to represent four cases, and the specific content is shown in table 2.
TABLE 2 OFDM symbol information field indication
| 2 bit OFDM symbol information field | Controlling OFDM symbols used by a set of channel resources |
| 00 | OFDM symbol 0 used |
| 01 | Used OFDM symbols 0 and 1 |
| 10 | OFDM symbols 0, 1 and 2 used |
| 11 | All OFDM symbols using one frame or slot |
Optionally, the frequency resource information is used to indicate frequency resources occupied by the control channel resources. The frequency resource information can accurately indicate the frequency resource occupied by the control channel resource, such as: and correspondingly, the user terminal can perform blind detection on the corresponding RB so as to improve the efficiency of the blind detection of the user terminal.
Optionally, the subframe information (subframe index) is used to indicate a sequence number of a subframe or slot in which the control channel resource is located. The subframe or slot where the control channel resource is located can be accurately indicated through the subframe information, so that the blind detection efficiency of the user terminal is improved. For example: the subframe information is used to indicate a sequence number for transmitting the control channel resource set subframe/slot within one or more frames. Taking the set of control channel resources as an example, the set of control channel resources may be sent periodically. If the period is a frame, and there are generally 10 subframes or slots in a frame, a bitmap (bitmap) with 10 bits can be used to indicate the sequence number of the subframe or slot for transmitting the control channel resource set. If the kth subframe transmits the set of control channel resources, the kth bit is set to 1, and the corresponding bit of the subframe that is not used to transmit the set of control channel resources is 0. For example, 0110000010 indicates that sub-frames 2, 3, and 9 may be used to convey the set of control channel resources. If the period is N frames, generally a frame has 10 subframes or slots, a bitmap method with 10N bits can be used to indicate the sequence number of the subframe/slot for transmitting the control channel resource set. With the subframe information, different sets of control channel resources may use the same frequency and OFDM resources, but are transmitted in different subframes to improve the flexibility of the system.
Optionally, before sending the configuration parameter of the control channel resource to the user terminal, the method further includes:
and configuring corresponding control channel resources for each bandwidth segment included by the carrier resources.
The configuring of the corresponding control channel resource for each bandwidth segment included in the carrier resource may be configuring a plurality of control channel resources according to the number of the bandwidth segments. In this embodiment, the base station configures corresponding control channel resources for each bandwidth segment, that is, each bandwidth segment configures corresponding control channel resources, and the bandwidth segments correspond to the control channel resources one to one. Thereby determining the bandwidth segment through the control channel resources. In addition, in the embodiment of the present invention, the corresponding relationship between the bandwidth segment and the control channel resource may be pre-configured to the user terminal.
Optionally, before the DCI format message is sent to the user terminal by using the control channel resource corresponding to the bandwidth segment for data transmission, the method further includes:
and sending the configuration parameters of the bandwidth segments to the user terminal.
The configuration parameters may be frequency domain configuration parameters of the bandwidth segments, and the base station and the user terminal may accurately and efficiently perform data transmission through the configuration parameters. Of course, in this embodiment, the base station may send configuration parameters of multiple bandwidth segments or all bandwidth segments to the user terminal, so that the base station may perform data transmission with the bandwidth segments of the user terminal in different time periods. In addition, the configuration parameter may be configured through RRC signaling, which is not limited in this embodiment of the present invention, for example: it may also be configured through other higher layer signaling.
Optionally, the configuration parameter includes at least one of:
frequency position, bandwidth, subcarrier interval, cell identification and sequence number of control channel resource corresponding to the bandwidth segment.
For example, taking a control channel resource set as an example, the configuration parameters may be as shown in table 3:
TABLE 3 information field of Bandwidth fragment configuration
In this embodiment, the user equipment may accurately determine the bandwidth segment corresponding to the control channel resource through the sequence number of the control channel resource corresponding to the bandwidth segment, so as to reduce the overhead of the DCI format message, and of course, the correspondence between the bandwidth segment and the control channel resource is not limited to be indicated by the configuration parameter, and may also be predefined by the user equipment and the base station or by a protocol, which is not limited in the embodiment of the present invention.

And allocating the bandwidth segment to the user terminal as the bandwidth segment for data transmission. The generating the DCI format message according to the allocated bandwidth segment may be generating a DCI format message corresponding to data transmission in the bandwidth segment, or generating a DCI format message corresponding to the bandwidth segment.
In this embodiment, it may be implemented to allocate a bandwidth segment to a user equipment, generate a corresponding DCI format message, and send the DCI format message in a corresponding control channel resource, so that the DCI format message sent to the user equipment may better meet the requirement of the user equipment, so as to improve the communication performance of the user equipment.
