It is understood that the invention is not limited to the described embodiments. All modifications, variations and equivalents are intended to be included within the scope of the appended claims.

Currently, for example, a base station may be required to assist a user equipment in establishing a direct (D2D) communication connection between devices, and dynamically allocating resources for direct (D2D) communication between devices. In this case, the user device needs to simultaneously dimension Two types of wireless links are guarded, that is, a communication link between the user equipment and the base station, and a communication link between the user equipment. While the inventors have realized in the process of implementing the present invention, for example, there may be the following situations in direct communication between devices: Case 1: The current communication mode of the user equipment is cellular communication, and the user equipment wishes to be converted into direct communication between devices. ;

Scenario 2: The current communication mode of the user equipment is direct communication between devices, and the frequency of direct communication between the devices used is ft. However, due to the increased interference on the frequency, one way to maintain direct communication between devices is to transfer On the frequency f ₂ of direct communication between another device;

Case 3: The current user equipment 1 is making direct communication with the user equipment 2, but the link quality of the direct communication between the user equipment 1 and the user equipment 2 is deteriorated (for example, the distance between the user equipment 1 and the user equipment 2) Further, the user equipment 1 needs to find another information source that can obtain the same information. The user equipment 3 continues to perform direct communication between the user equipments;

Scenario 4: The communication mode of the current user equipment is direct communication between user equipments, and the frequency of direct communication between the user equipments used is ft. At this time, the network side needs real-time understanding of the current direct communication between the user equipments of the user equipment. The channel quality of the road to determine whether to switch to other frequencies for communication to achieve better throughput and quality of service.

In the above scenario, the network side needs to obtain the link channel conditions in which the current user equipment is performing direct communication between devices or an alternative link channel condition in which direct communication between devices can be performed. However, there is currently no corresponding resource allocation method for link measurement and direct measurement reporting mechanism for direct communication between devices.

Thus, for example, when the above situation is encountered (but not limited to these cases), the user equipment cannot effectively perform link measurement of direct communication between devices, thereby failing to effectively perform frequency selection of direct communication between devices, or directly communicating between devices. Mode conversion between cellular communication.

The embodiment of the invention provides a resource configuration method, a link measurement method, a measurement result reporting method and a device for link measurement of direct communication between devices, and the user equipment can perform effective direct communication between devices based on resource information configured on the network side. Link measurement, which helps the network side to know the ongoing or alternative link channel conditions for direct communication between devices, so that the network side can reasonably and efficiently perform the frequency selection of direct communication between devices, or directly communicate between devices. Mode conversion between cellular communication.

Therefore, with the embodiment of the present invention, the user equipment can perform effective link measurement of direct communication between devices based on resource information configured on the network side, thereby helping the network side to learn about an ongoing or alternative chain that can directly communicate between devices. Channel channel condition, the frequency of direct communication between devices is reasonably and efficiently based on the link channel conditions. Rate selection, or mode conversion between direct communication between devices and cellular communication.

The following describes the resource configuration method, the link measurement method, and the measurement result of the direct communication between devices in the embodiment of the present invention by using the network side base station that configures the resource information of the link measurement and the user equipment that performs the link measurement as an example. The method is described in detail. Example 1

1 is a flow chart of a resource configuration method according to Embodiment 1 of the present invention. Corresponding to the network side, as shown in Figure 1, the method includes:

Step 101: The network side configures, for the user equipment, resource information for link measurement for direct (D2D) communication between devices;

The resource information includes information about a time domain resource, and/or a frequency domain resource and/or a code domain resource.

In this embodiment, as shown in FIG. 1, the method further includes step 102, notifying the configured user equipment information to the user equipment;

In this way, the user equipment can perform link measurement of the D2D communication based on the resource information, where the resource information can be notified by any kind of message, and details are not described herein again.

In this embodiment, the time domain resource configured on the network side indicates which subframes on the time domain the user equipment can perform link measurement for direct communication between devices. The time domain resource may include a measurement period and/or a starting point of each period, and a subframe position for performing link measurement in each period.

There are various ways to configure the time domain resource, for example:

Method 1: Configure time domain resources in the form of bitmap images. For example, Figure 2 is a schematic diagram of configuring a time domain resource using a bitmap. As shown in FIG. 2, a bitmap image configuration method with a period of 40 ms and a system frame number (SFN, System Frame Number) mod 4=0 as a starting point is shown, as shown in FIG. 2, if the bit position is If set to 1, it means that the measurement can be performed on the subframe corresponding to the bit; if the bit is set to 0, it means that the measurement is not performed on the subframe corresponding to the bit, and vice versa. In the above embodiment, the period and the starting point may be determined according to actual conditions, and are not limited to the above embodiment. Manner 2: The network side presets a mapping relationship between the first index value and the time domain resource, and indicates the time domain resource by using the configured first index value. For example, Table 1 exemplarily shows the mapping relationship between the configured index value and the time domain resource, where the cycle start point is a frame of the system frame number (SFN, System Frame Number) mod P/10=0, where P is The period, the configuration index value 0 indicates that the measurement is performed on the #0 subframe with a period of 40 ms, and the configuration index value 1 indicates that the measurement is performed on the #1 subframe set with the period of 40 ms, ..., the configuration index value n indicates that the period is #m, ······· #1^ The measurement is performed on the sub-frame set, where n is an integer greater than or equal to zero; P, m, and k are integers greater than or equal to zero.

Table 1

In this embodiment, the frequency domain resource configured on the network side indicates which physical resource blocks (PRBs) on the frequency domain can perform link measurement on direct communication between devices. For example, in the configured frequency domain resource, as long as the location of the physical resource block is specified, the user equipment can perform link measurement of direct communication between devices on the corresponding physical resource block, for example, in the corresponding physical resource block. The specific location, for example, is measured on the last Orthogonal Frequency Division Multiplexing (OFDM) symbol, but can also be measured on other OFDM symbols.

There are various ways to configure the frequency domain resources, for example:

Manner 1 indicates the physical resource block to be used by indicating the starting position and length of the physical resource block. In this way, the location of the physical resource block can be determined, and the user equipment can perform link measurement of direct communication between devices (D2D) on the corresponding physical resource block.

Manner 2: The mapping relationship between the second index value preset by the network side and the frequency domain resource, and the frequency domain resource is indicated by the configured second index value. For example, Table 2 exemplarily shows the mapping relationship between the configured index value and the frequency domain resource, wherein the configuration index value 0 indicates that the measurement is performed on the resource block of the frequency domain #0, and the configuration index value 1 indicates the frequency domain # The measurement is performed on the resource block set of 1, ..., the configuration index value n represents the resources in the frequency domain #m, ... #k Measurements are taken on the block set. The values of n, m, and k are as described above, and are not described here.

Table 2

In this embodiment, the code domain resource configured on the network side indicates the code domain sequence label and sequence information of the measurement object to be measured, and the measurement object may be a link or a frequency to be measured.

For example, the communication frequency of direct communication between devices (D2D) is ft, UE1 and UE2 communicate in frequency ft by D2D mode, and UE1 and UE3 communicate in frequency ft by D2D mode, if the base station instructs UE1 to measure between UE1 and UE2. communication link, the measurement object is a communication link between the UE1 and UE2; as another example, UE1 and UE2 way D2D communication using frequency. ft, UE1 and UE3 way D2D communication using a frequency f _2, if the base station indicates UE1 measures the communication link between UE1 and UE2, and the measurement object is the communication frequency between UE1 and UE2.
