Fig. 1 is a schematic flow chart illustrating an implementation of a first embodiment of an information processing method applied to a base station according to the present invention; as shown in fig. 1, the method includes:

step 101: detecting whether first transmission request information sent by the first electronic device is received, wherein the first transmission request information requests the base station to allocate first transmission resources for first transmission for the first electronic device, the first transmission is transmission between the first electronic device and second electronic device, and the first transmission request information at least includes identification information of the second electronic device;

here, taking as an example that the first electronic device is device 1, the second electronic device is device 2, and device 2 supports unicast transmission, the first transmission is D2D transmission between device 1 and device 2; the first transmission resource may be a resource block, such as a time resource, a frequency resource, etc., used by the device 1 when performing D2D transmission. After determining that the object performing D2D transmission with the device 2 is the device 2, the device 1 sends first transmission request information carrying the device 2 identification ID to the base station, so as to request the base station to allocate the resource block used for D2D transmission to the device 1 and request to acquire resource block information used when the device 2 performs uplink transmission.

Step 102: when the first transmission request information is received, sending first response information aiming at the first transmission request information to the first electronic equipment, wherein the first response information at least comprises first transmission resources, and the first transmission resources are used for representing transmission resources used by the first electronic equipment in first transmission; and sending, to the first electronic device, a second transmission resource of the second electronic device, where the second transmission resource is used to characterize a transmission resource used by the second electronic device in a second transmission, and the second transmission is between the second electronic device and the base station.

Here, the second transmission may be transmission between the device 2 and the base station, specifically, uplink transmission, and the second transmission resource is an uplink transmission resource used by the device 2. After receiving the first transmission request, the base station allocates a D2D transmission resource to the device 1, and sends the D2D transmission resource allocated to the device 1 and transmission resource information used by the device 2 in uplink transmission to the device 1, so that the device 1 initiates D2D transmission to the device 2 by using the transmission resource information.

Since D2D transmissions all occur in uplink resources of Time Division Duplex (TDD), after the base station receives the first transmission request sent by the device 1, the base station allocates, to the device 1, uplink resources used for D2D transmissions, and at the same Time, the base station performs uplink scheduling on the device 2 and allocates, to the device 2, uplink resources used for uplink transmissions; the uplink resource information allocated to the device 1 and the device 2 is returned to the device 1, so that the device 1 initiates D2D transmission to the device 2 by using the uplink resource information.

Correspondingly, fig. 2 is a schematic flow chart illustrating an implementation of the first embodiment of the information processing method applied to the first electronic device according to the present invention; the first electronic device is capable of D2D transmission with a second electronic device, as shown in fig. 2, the method includes:

step 201: acquiring a first transmission resource of first electronic equipment, wherein the first transmission resource is used for representing the transmission resource used by the first electronic equipment in first transmission;

here, the device 1 acquires the first transmission resource by receiving the D2D transmission resource allocated for the device 1 transmitted by the base station.

Step 202: acquiring a second transmission resource of a second electronic device, wherein the second transmission resource is used for representing a transmission resource used by the second electronic device during second transmission, and the second transmission is transmission between the second electronic device and a base station;

here, the device 1 acquires the second transmission resource by receiving uplink transmission resource information allocated to the device 2 transmitted by the base station.

It should be noted that

steps

201 and 202 do not have a strict sequence, and may also be performed simultaneously.

Step 203: detecting the first transmission resource and the second transmission resource to generate a first detection result;

here, it is detected whether a first transmission resource used for D2D transmission between device 1 and device 2 and a second transmission resource used for uplink transmission between device 2 and the base station collide.

Step 204: determining a transmission resource which accords with a first preset rule in the first transmission resources as a third transmission resource in the first detection result;

here, the device 1 selects, as the third transmission resource, a transmission resource that does not collide with the second transmission resource among the first transmission resources.

Step 205: initiating a first transmission to the second electronic device using the third transmission resource.

Here, device 1 makes a D2D transmission to device 2 using a third transmission resource that does not collide with the second transmission resource to avoid collision and so that uplink transmissions are not delayed by D2D transmissions.

Therefore, in this embodiment, the D2D transmission resource allocated by the base station to the first electronic device and the uplink transmission resource allocated by the base station to the second electronic device are detected, and the D2D transmission resource that does not conflict with the uplink transmission resource is selected as the transmission resource used when the first electronic device initiates the D2D transmission to the second electronic device 2, so that the conflict between the uplink transmission and the D2D transmission is avoided, the uplink transmission and the D2D transmission are performed normally, and the uplink transmission is not delayed by the D2D transmission.

The second embodiment of the information processing method applied to the base station provided by the invention, the base station can communicate with the first electronic equipment; the first electronic device may preferably be a mobile phone.

Fig. 3 is a schematic flow chart illustrating an implementation of a second embodiment of the information processing method applied to a base station according to the present invention; as shown in fig. 3, the method includes:

step 301: detecting whether first transmission request information sent by the first electronic device is received, wherein the first transmission request information requests the base station to allocate first transmission resources for first transmission for the first electronic device, the first transmission is transmission between the first electronic device and second electronic device, and the first transmission request information at least includes identification information of the second electronic device;

The process of determining that the object with which the device 1 performs D2D transmission is the device 2 is as follows:

the method comprises the steps that first information is sent to a second electronic equipment set by first electronic equipment, wherein the second electronic equipment set is a set of electronic equipment within a preset range from the first electronic equipment; receiving second information sent by electronic equipment in the second electronic equipment set, wherein the second information at least comprises identification information of the electronic equipment sending the second information; and determining second electronic equipment performing first transmission with the first electronic equipment according to the identification information. Specifically, the device 1 initiates the first information discovery to the second electronic device set, the device receiving the discovery feeds back its own ID to the device 1, and confirms the electronic device (the second electronic device) performing the unicast transmission of D2D with the device 1 according to the received ID information.

Step 302: when the first transmission request information is received, sending first response information aiming at the first transmission request information to the first electronic equipment, wherein the first response information at least comprises first transmission resources, and the first transmission resources are used for representing transmission resources used by the first electronic equipment in first transmission; and sending, to the first electronic device, a second transmission resource of the second electronic device, where the second transmission resource is used to characterize a transmission resource used by the second electronic device in a second transmission, and the second transmission is between the second electronic device and the base station.

Here, the second transmission may be transmission between the device 2 and the base station, specifically, uplink transmission, and the second transmission resource is an uplink transmission resource used by the device 2. After receiving the first transmission request, the base station allocates a D2D transmission resource to the device 1, and sends the D2D transmission resource allocated to the device 1 and uplink transmission resource information used by the device 2 in uplink transmission to the device 1, so that the device 1 initiates D2D transmission to the device 2 by using the transmission resource information.

Since D2D transmissions all occur on uplink resources of Time Division Duplex (TDD), after the base station receives the first transmission request sent by the device 1, the base station allocates, to the device 1, uplink resources used for D2D transmissions, and meanwhile, the base station performs uplink scheduling on the device 2 to allocate, to the device 2, uplink resources used for uplink transmissions; and return the uplink resource information allocated to device 1 and device 2 to device 1, so that device 1 initiates D2D transmission to device 2 using the uplink resource information.

In a preferred embodiment of the present invention, the method further comprises:

the base station detects whether third information sent by the first electronic device, such as device 1, is received, the third information is that the first electronic device notifies the base station to stop sending the second transmission resource of the second electronic device to the first electronic device, and when the third information sent by device 1 is detected to be received, the base station stops sending uplink transmission resource information allocated by the base station to the second electronic device to the first electronic device.

Correspondingly, fig. 4 is a schematic flow chart illustrating an implementation of the second embodiment of the information processing method applied to the first electronic device according to the present invention; the first electronic device is capable of D2D transmission with a second electronic device, as shown in fig. 4, the method includes:

step 401: acquiring a first transmission resource of first electronic equipment, wherein the first transmission resource is used for representing the transmission resource used by the first electronic equipment in first transmission;

Step 402: acquiring a second transmission resource of a second electronic device, wherein the second transmission resource is used for representing a transmission resource used by the second electronic device during second transmission, and the second transmission is transmission between the second electronic device and a base station;

It should be noted that

steps

401 and 402 do not have a strict sequence, and may also be performed simultaneously.

Step 403: acquiring M first attributes of M first transmission sub-resources in the first transmission resources, and acquiring N second attributes of N second transmission sub-resources in the second transmission resources; comparing the M first attributes with the N second attributes to obtain a first detection result;

here, when the first transmission resource and the second transmission resource are both time-frequency resources, both the first transmission sub-resource and the second transmission sub-resource may be time-frequency resource units, and the first attribute and the second attribute are time slots of the time-frequency resource units, after acquiring a time slot of a time-frequency resource unit (first transmission resource) used by the device 1 in D2D transmission and acquiring a time slot of a time-frequency resource unit (second transmission resource) used by the device 2 in uplink transmission, comparing the two time slots, and generating a first detection result.

This step may be used as a further description of detecting the first transmission resource and the second transmission resource and generating a first detection result in the embodiment of the present invention.

Step 404: determining L first attributes different from the N second attributes in the first detection result; selecting a first transmission sub-resource corresponding to the L first attributes as a third transmission resource;

m, N is a positive integer, L is an integer of 0 or more; in the first transmission resource, the time-frequency resource units corresponding to the time slots different from the time slots of all the time-frequency resource units in the second transmission resource are selected as the third transmission resource, that is, the first transmission resource which does not conflict with the second transmission resource is selected as the third transmission resource.

This step may be further described as determining, in the first detection result, a transmission resource that meets a first predetermined rule in the first transmission resources as a third transmission resource.

Step 405: initiating a first transmission to the second electronic device using the third transmission resource.

Here, the device 1 transmits the D2D data to the device 2 using a third transmission resource that does not collide with the second transmission resource to avoid a transmission collision between the D2D transmission of the device 1 and the uplink transmission of the device 2 while making the uplink transmission of the device 2 not delayed by the D2D transmission of the device 1.

In a preferred embodiment of the present invention, the obtaining M first attributes of M first transmission sub-resources in the first transmission resource includes:

determining a first transmission sub-resource in a first transmission resource adopted for next transmission in first transmission as a first target sub-resource, and acquiring a first attribute of the first target sub-resource; correspondingly, after acquiring the N second attributes of the N second transmission sub-resources in the second transmission resource, the method further includes: comparing the first attribute of the first target sub-resource with the N second attributes, and judging whether the first attribute of the first target sub-resource is the same as the N second attributes or not; if the first target sub-resource is judged to be not the same as the second target sub-resource, selecting the first target sub-resource as a third transmission resource; and if so, not initiating the first transmission to the second electronic equipment on the first target sub-resource. Specifically, when determining which time-frequency resource unit is used for the next D2D transmission, determining the time slot of the time-frequency resource unit, and determining whether the time slot of the time-frequency resource unit is the same as the time slots of all the time-frequency resource units in the second transmission resource, if the time slots of the time-frequency resource unit are determined to be different from the time slots of all the time-frequency resource units in the second transmission resource, the device 1 uses the time-frequency resource unit as a third transmission resource, and performs D2D transmission to the device 2 by using the time-frequency resource; when the same is determined to exist, the device 1 does not perform D2D transmission on the time-frequency resource unit.

In a further preferred embodiment of the present invention, the method further comprises:

when the first transmission resource, i.e., D2D transmission resource, is not exhausted, determining whether the first transmission is completed, i.e., determining whether the D2D transmission between device 1 and device 2 is completed;

when the judgment result shows that the first transmission is finished, the first electronic device sends third information such as a notification message to the base station to notify the base station to stop sending the second transmission resource of the second electronic device to the first electronic device;

when the determination result indicates that the first transmission is not completed, the first electronic device continues to send the first transmission request message to the base station to request the base station to allocate the D2D transmission resource for the base station again, and completes the D2D transmission according to the foregoing method, such as steps 401 to 405.

Correspondingly, when the base station detects that the third information such as the notification message is received, the base station stops sending the uplink transmission resource information allocated to the second electronic device to the first electronic device.

Therefore, in this embodiment, the D2D transmission resource allocated by the base station to the first electronic device and the uplink transmission resource allocated by the base station to the second electronic device are detected, and the D2D transmission resource that does not conflict with the uplink transmission resource is selected as the transmission resource used when the first electronic device initiates the D2D transmission to the second electronic device, so that the conflict between the uplink transmission and the D2D transmission is avoided, the uplink transmission and the D2D transmission are performed normally, and the uplink transmission is not delayed by the D2D transmission.

According to a first embodiment of the base station provided by the present invention, the base station is capable of communicating with a first electronic device; the first electronic device may preferably be a mobile phone.

here, taking as an example that the first electronic device is device 1, the second electronic device is device 2, and device 2 supports unicast transmission, the first transmission is D2D transmission between device 1 and device 2; the first transmission resource may be a resource block, such as a time resource, a frequency resource, etc., used by the device 1 when performing D2D transmission. In this embodiment, the first electronic device is the electronic device illustrated in fig. 6. After the device 1, specifically the first determining unit 604 determines that the object performing D2D transmission with the device 1 is the device 2, the first transmitting unit 605 sends first transmission request information carrying the identity ID of the device 2 to the base station, and the base station, specifically the first detecting unit 501, detects whether the request is received.
