(Frequency Division Duplexing, abbreviated as FDD) mode and Time Division Duplexing (TDD) mode.

Among them, the FDD mode communication system needs two independent channels when working, one channel (such as frequency F1) is used to transmit information downwards, and another channel (such as frequency F2) is used to transmit information upwards. In addition, the TDD mode communication system receives and transmits different time slots on the same frequency channel (i.e., carrier 1 or frequency F1) during operation, and separates the receiving and transmitting channels with guaranteed time. Therefore, in the prior art, both the base station and the terminal are in a half-duplex mode of operation, that is, the base station or the terminal is on the same frequency resource, either receiving information or transmitting information.

For a network deployed by a full-duplex base station (a base station can simultaneously transmit and receive information using the same frequency), how a half-duplex terminal in a mobile communication system selects an appropriate resource configuration to communicate with a base station is a problem to be solved. In addition, for a full-duplex base station, when the usage of the resources by the terminals is unbalanced, the network load is unbalanced and the data transmission efficiency is low. Therefore, for the full-duplex base station, how to perform resources on the terminal after the terminal accesses Reconfiguration is also a problem that needs to be solved.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. example. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. FIG. 1 is a schematic diagram of a prior art FDD mode transmission. As shown in FIG. 1 , a Long Term Evolution (Advanced) (LTE-A) system includes an evolved Node B (eNB) and a User Equipment (UE). The eNB is in a full-duplex mode, and the eNB can pass the eNB. The transmitting antenna simultaneously transmits the downlink data of UE1 and UE2 in the two frequency bands F1 and F2, and the eNB can receive the uplink data of UE2 and UE1 in the two frequency bands F1 and F2 through the receiving antenna at the same time; the UE is a half-duplex working mode. The UE1 sends uplink data in the F2 frequency band and downlink data in the F1 frequency band. The UE2 sends uplink data in the F1 frequency band and downlink data in the F2 frequency band. That is to say, for a half-duplex terminal in an FDD mode communication system, it is necessary to select a frequency band resource configuration mode for data transmission.

The eNB can send downlink data to the UE1 in the time slot n. The slot n receives the uplink data of the UE2, the eNB may receive the uplink data of the UE1 in the slot n+k, and send the downlink data to the UE2 in the slot n+k; the UE is in the half-duplex working mode, where the UE1 receives in the slot n Downstream data, transmitting uplink data in slot n+k; UE2 transmitting uplink data in slot n and receiving downlink data in slot n+k.

S302. The communication node determines a resource configuration used by the terminal to send signaling or data. Specifically, the communication node can learn the transmission resource used by the terminal to send the information (the signaling or the data) by receiving the information sent by the terminal, and then further determine the resource configuration used by the terminal by using the transmission resource used by the terminal. Wherein, the resource configuration

S 303: If the resource is configured as the first resource, determine that the terminal is the first terminal; or, if the resource is configured as the second resource, determine that the terminal is the second terminal.

Specifically, the communication node can learn the time-frequency resource configuration used by the terminal to send signaling or data (for example, the communication node receives on the time-frequency domain resource with the center frequency of F1 and the bandwidth of 10 MHz on the K-subframe of the S-frame. The information/signal sent to the terminal, and then determining the terminal type according to the resource configuration used by the terminal, wherein the terminal type is divided according to the resource configuration used by the terminal.

In this embodiment, after receiving the signaling or data sent by the terminal, the communication node determines whether the terminal is the first terminal or the second terminal by determining the resource configuration used by the signaling or data sent by the terminal, because the terminal type is According to the resource configuration used by the terminal, the number of terminals configured with different resources can be known, and the resource configuration used by the terminal to adjust the communication between the terminal and the communication node can be adjusted by sending a message to the terminal, thereby achieving network load balancing. , improve data transmission efficiency is low.

The first resource and the second resource configuration are time-frequency resource configurations. For example, the specific implementation may be:

In the first manner, specifically, the communication node notifies the resource configuration used by the terminal to communicate with the communication node by broadcasting or by transmitting a dedicated signaling manner to the terminal. For example, the terminal is instructed to communicate with the communication node using the first resource configuration. Or,

In the second manner, specifically, the terminal is aware of the resource configuration used by the terminal to communicate with the communication node (for example, there may be two types of resource configurations, a first resource configuration and a second resource configuration). The communication node transmits the priority of the dedicated signaling mode resource configuration to the terminal by broadcasting or by, for example, indicating that the terminal preferentially uses the second resource configuration to communicate with the communication node. Or,

In a third mode, specifically, the communication node notifies the terminal of the resource configuration used by the terminal to communicate with the communication node by broadcasting or by transmitting a dedicated signaling manner to the terminal, and the priority of the resource configuration used by the terminal.

Or,

FIG. 6 is a flowchart of Embodiment 6 of a data transmission method according to the present invention. As shown in Fig. 6, the method of the embodiment may include the following.

S601. The terminal determines a resource configuration as a resource configuration used by the terminal.

The resource configuration that can be used by the terminal includes: a first resource configuration and a second resource configuration, where

Specifically, the first resource configuration may be configured as a first resource for uplink transmission between the terminal and the communication site link (eg, the uplink is sent by the terminal to the communication node), and the second resource is configured to be used between the terminal and the communication site link. Downlink transmission (for example, the downlink is sent by the communication node to the terminal).

When applied to a frequency division duplex FDD system, the first resource includes: a frequency band with a center frequency of {fll, ···, fli, —fin}, or includes: a carrier {Cll, one, Cli~Cln}, where Lin iL n> l; the second resource includes: a frequency band with a center frequency of {f21, ···, f2j, ~f2m}, or includes: carrier {C21, one, 02 "0201}, where 1 jm and m > l; or,

When the transmission method is applied to a time division duplex TDD system, the first resource includes: a time slot s, a frequency band whose center frequency is {Π1,···, fli, —fin}, or includes: a time slot s, a carrier {Cll,..., Cli—Cln} , where 1 in and n> 1; the second resource includes: a time slot s+k, a frequency band with a center frequency of {Π1,···, fli, —fin}, or Including: time slot s+k, carrier {Cll,..., Cli-Cln}, where lin iL n> l.

In addition to the foregoing configuration, the first resource configuration includes when the terminal communicates with the communication node. Configuration information such as bandwidth, center frequency, and transmit power. For the case where the terminal and the communication node only use one carrier communication: for example, the first resource F1 frequency (or carrier C11) is used for uplink transmission between the terminal and the communication station link, the center frequency is fll, the bandwidth is 1 , and the uplink Configuration information such as transmit power P1. The second resource F2 frequency (or carrier C21) is used for downlink transmission between the terminal and the communication station link, where the central frequency point is f 21 and the bandwidth is 2 and other configuration information.

Similarly, the second resource is configured to configure the first resource for downlink transmission between the terminal and the communication site link, and configure the second resource for uplink transmission between the terminal and the communication site link. In addition to the foregoing configuration, the second resource configuration includes configuration information such as bandwidth, center frequency, and transmit power when the terminal communicates with the communication node. The detailed description is similar to the first resource configuration, and will not be described again.

Determining, by the terminal, a resource configuration as a resource configuration used by the terminal: First, the terminal selects a resource configuration from a resource configuration that it can use. For example, the terminal may randomly select a resource configuration from the resource configuration in which it can use the support; for example, the terminal may also measure the first resource (eg, carrier Cl1, C12~) and the second resource (eg, carriers C21 and C22). According to the measurement result (that is, the signal of the communication node is detected on the above carrier), the resource configuration used by the terminal is determined according to the signal quality.

The second possibility is that the terminal listens to the system message sent by the communication node, and obtains the resource configuration used by the terminal to communicate with the communication node from the system message, thereby determining a resource configuration as the resource configuration used by the terminal. For example, the system message may include a first resource configuration and a second resource configuration, and a priority of the terminal using the resource configuration, thereby determining a resource configuration as the resource configuration used by the terminal according to the foregoing information. For example, the system message may include one of the two configurations (e.g., the first resource configuration), thereby determining a resource configuration as the resource configuration used by the terminal according to the above information.

A third possibility is that the terminal receives the dedicated message sent by the communication node, and obtains the resource configuration used by the terminal to communicate with the communication node from the dedicated message, thereby determining a resource configuration as the resource configuration used by the terminal. For example, the dedicated resource may include a first resource configuration and a second resource configuration, and a priority of the terminal using the resource configuration, thereby determining a resource configuration as the resource configuration used by the terminal according to the foregoing information. For example, the dedicated message may include one of the two configurations (eg, the first resource configuration), thereby determining a resource configuration as the resource configuration used by the terminal according to the foregoing information. This is similar to the second possibility. For the fourth possibility, the terminal finally determines a resource configuration as the resource configuration used by the terminal according to its own identifier (for example, IMS I) through some calculation method. For example, (T/N) * (UE ID modN), the calculated value, for example, the odd number uses configuration 1, and the even number uses configuration 2, where the UE ID is the terminal identifier, such as IMS I or IMS Imodl 024, T is a period, N is the paging frame number of the paging UE. The invention does not limit specific technical formulas and calculation methods.

S602. The terminal sends signaling or data to the communication node by using the determined resource configuration. The first terminal is a terminal that communicates with the communication node by using the first resource, and the second terminal is a terminal that communicates with the communication node by using the second resource.

Specifically, the signaling or data sent by the terminal to the communication node may be any data information, and the communication node may determine the resource configuration used by the terminal through the data sent by the terminal, and finally determine the terminal type. The terminal type is divided according to the resource configuration used by the terminal.

Specifically, the signaling sent by the terminal to the communication node, such as an introduction message (preamb le ), an access message, an RRC message, a MAC layer message, a physical layer message, etc., the data sent by the terminal to the communication node may be in various forms. For example, da ta pacek t , PDU, etc., are not limited in the present invention.

The communication node determines the terminal type according to the resource configuration division used by the terminal. Specifically, the communication node determines the terminal type by determining the resource configuration used by the terminal. Specifically, the first possibility is that the communication node receives the information (such as signaling or data) sent by the terminal on a certain resource block, and determines the resource configuration used by the terminal according to the resource used by the terminal to send the information, Thereby determining the terminal type. For example, the communication node receives the information transmitted by the terminal on the first resource (e.g., carrier C11), thereby determining that the terminal uses the first resource configuration to communicate with the communication node. It is thus determined that the terminal is the first terminal. For the specific terminal to determine the resource configuration used, refer to the first mode to the fourth mode in step S601.

The second possibility is that the communication node sends a dedicated message, and after receiving the dedicated message, the terminal obtains the resource configuration used by the terminal to communicate with the communication node, and the terminal determines a resource configuration as the resource configuration used by the terminal. For example, the dedicated resource may include a first resource configuration and a second resource configuration, and a priority of the terminal using the resource configuration (eg, preferentially using the first resource configuration), thereby determining, according to the information terminal, that the second resource is configured to be used by the terminal. Resource configuration. Before/after/after the communication node sends the dedicated message, the communication node can determine that the terminal is the second terminal. Or after the dedicated message is sent and the received terminal receives the information (such as a reply message, or other signaling or data) sent by the terminal on the second resource, the communication node determines that the type of the terminal is the second terminal. Or after sending a dedicated message and Receiving information sent by the terminal using the original resource configuration (for example, the terminal uses the first resource configuration before/when the dedicated message is received), and receiving information (such as a reply message, or other signaling or data) sent by the terminal, Thereby the communication node determines that the type of the terminal is the second terminal.
