DETAILED DESCRIPTION

Hereinafter, preferable embodiments of the present disclosure will be described in detail with reference to the accompany drawings. It should be understood that the preferable embodiments described in the following are only for an explanation and an interpretation of the present disclosure, but not for a limitation to the present disclosure.

In the information processing method and the electronic device provided the embodiments of in the present disclosure, the related first electronic device (electronic device) and the second electronic device include, but not limit to, various kinds of computer such as a industrial controlled computer, a personal computer, or the like, a all-in-on computer, a tablet computer, a cell phone, an electronic reader, or the like. The first electronic device (electronic device) in an optional embodiment of the present disclosure is the cell phone.

In the first embodiment of the information processing method applied to the base station provided in the present disclosure, the base station can communicate with the first electronic device which may be the cell phone optionally.

FIG. 1 is a schematic flowchart of the information processing method applied to the base station provided in the first embodiment of the present disclosure. As shown in FIG. 1, the method comprises the following steps.

In a step 101, it is detected whether first transmission request information transmitted from the first electronic device is received or not, the first transmission request information being used by the first electronic device for requesting the base station to allocate a first transmission resource for a first transmission, as a transmission resource between the first electronic device and a second electronic device, the first transmission request information comprising at least identification information of the second electronic device.

Herein, taking an example in which the first electronic device is a device 1 and the second electronic device is a device 2 supporting the unicast transmission, the first transmission is the D2D transmission between the device 1 and the device 2. The first transmission resource may be a resource block used in the D2D transmission by the device 1, such as the time resource, the frequency resource, or the like. The device 1 transmits the first transmission request information carrying the ID of the device 2 to the base station after determining that the target of the D2D transmission is the device 2, to request the base station to allocate the resource block used in the D2D transmission for the device 1, and to request to acquire resource block information used by the device 2 in the uplink transmission.

In a step 102, first response information for the first transmission request information is transmitted to the first electronic device when the first transmission request information is received, the first response information comprising at least the first transmission resource assignment indicating transmission resource used by the first electronic device in a first transmission； and second transmission resource assignment for the second electronic device is transmitted to the first electronic device, the second transmission resource assignment indicating a transmission resource used by the second electronic device in a second transmission, as a transmission resource between the second electronic device and the base station.

Herein, the second transmission may be a transmission between the device 2 and the base station, particularly an uplink transmission. The second transmission resource may be the uplink transmission resource used by the device 2. After the base station has received the first transmission request information, it allocates the D2D transmission resource for the device 1, and transmits the D2D transmission resource assignment allocated for the device 1 and the transmission resource information used by the device 2 in the uplink transmission, to the device 1, so that the device 1 uses these transmission resource information for the D2D transmission to the device 2.

Since the D2D transmission all occurs in the uplink resource which is time division duplexed (TDD) , after the base station has received the first transmission request information transmitted from the device 1, the base station allocates the uplink resource used in the D2D transmission for the device 1. Meanwhile, the base station performs uplink schedule for the device 2 and allocates the uplink resource used in the uplink transmission for the device 2, and returns the uplink resource information allocated for the devices 1 and 2 to the device 1, so that the device 1 uses these uplink resource information to perform the D2D transmission to the device 2.

Accordingly, FIG. 2 is a schematic flowchart of the information processing method applied to the first electronic device provided in the first embodiment of the present disclosure, the first electronic device being capable of performing the D2D transmission with the second electronic device. As shown in FIG. 2, the method comprises the following steps.

In a step 201, a first transmission resource assignment for the first electronic device is received, the first transmission resource assignment indicating a transmission resource used by the first electronic device in a first transmission.

Here, the device 1 receives the first transmission resource assignment by receiving the D2D transmission resource allocated to the device 1 by the base station.

In a step 202, a second transmission resource assignment for the second electronic device is received for indicating a transmission resource used by the second electronic device in a second transmission as a transmission resource between the second electronic device and a base station.

Here, the device 1 receives the second transmission resource assignment by receiving the uplink transmission resource information allocated to the device 2, which is transmitted by the base station.

It is to be noted that there is no strict order between the

steps

201 and 202, and they may be performed concurrently.

In a step 203, the first transmission resource assignment and the second transmission resource assignment are detected to generate a first detection result.

Here, it is detected whether there is a conflict between the first transmission resource assignment used for the D2D transmission between the device 1 and the device 2 and the second transmission resource assignment used for the uplink transmission between the device 2 and the base station.

In a step 204, a transmission resource meeting a first predetermined rule among the first transmission resource assignment is determined as a third transmission resource, in the first detection result.

Here, the device 1 selects the transmission resource in which there is no conflict between the first transmission resource assignment and the second transmission resource assignment, as the third transmission resource.

In a step 205, the first transmission to the second electronic device is performed with the third transmission resource.

Here, the device 1 uses the third transmission resource which does not conflict with the second transmission resource, to perform the D2D transmission with the device 2 to avoid any conflict and to make the uplink transmission not be delayed by the D2D transmission.

It can be seen that in the present embodiment, the D2D transmission resource allocated to the first electronic device by the base station and the uplink transmission resource allocated to the second electronic device by the base station are detected, and the D2D transmission resource which does not conflict with the uplink transmission resource is selected as the transmission resource used for the D2D transmission from the first electronic device to the second electronic device, thereby the conflict between the uplink transmission and the D2D transmission is avoided so that the uplink transmission and the D2D transmission can be performed normally and the uplink transmission won’t be delayed by the D2D transmission.

In the second embodiment of the information processing method applied to the base station provided in the present disclosure, the base station can communicate with the first electronic device which may be the cell phone optionally.

FIG. 3 is a schematic flowchart of the information processing method applied to the base station provided in the second embodiment of the present disclosure. As shown in FIG. 3, the method comprises the following steps.

In a step 301, it is detected whether first transmission request information transmitted from the first electronic device is received or not, the first transmission request information being used by the first electronic device for requesting the base station to allocate a first transmission resource for a first transmission, as a transmission resource between the first electronic device and a second electronic device, the first transmission request information comprising at least identification information of the second electronic device.

Herein, taking an example in which the first electronic device is a device 1 and the second electronic device is a device 2 supporting the unicast transmission, the first transmission is the D2D transmission between the device 1 and the device 2. The first transmission resource may be a resource block used in the D2D transmission by the device 1, such as the time resource, the frequency resource, or the like. The device 1 transmits the first transmission request information carrying the ID of the device 2 to the base station after determining that the target of the D2D transmission is the device 2, to request the base station to allocate the resource block used in the D2D transmission for the device 1, and to request to acquire resource block information used in the uplink transmission by the device 2.

Here, the process of the device 1 determining the target of the D2D transmission being the device 2 is as follows.

The first electronic device transmits the first information to a set of the second electronic devices. The set of the second electronic devices is a set of electronic devices in a preset range from the first electronic device. The second information transmitted from the electronic device in the set of the second electronic devices is received, which comprises at least the identification information of the electronic device transmitting the second information. The second electronic device to which the first transmission is performed by the first electronic device is determined based on the identification information. In particular, the device 1 transmits the first information ‘discovery’ to the set of the second electronic devices, the device receiving the ‘discovery’ feeds back to the device 1 with its ID, and the electronic device (the second electronic device) to which the D2D unicast transmission is performed by the device 1 is determined by the device 1based on the received ID information.

In a step 302, first response information for the first transmission request information is transmitted to the first electronic device when the first transmission request information is received, the first response information comprising at least the first transmission resource assignment indicating transmission resource used by the first electronic device in a first transmission； and second transmission resource assignment for the second electronic device is transmitted to the first electronic device, the second transmission resource assignment indicating a transmission resource used by the second electronic device in a second transmission as a transmission between the second electronic device and the base station.

Since the D2D transmission all occurs in the time division duplexed (TDD) uplink resource, after the base station has received the first transmission request information transmitted from the device 1, the base station allocates the uplink resource used in the D2D transmission for the device 1. Meanwhile, the base station performs uplink schedule for the device 2 and allocates the uplink resource used in the uplink transmission for the device 2, and returns the uplink resource information allocated for the devices 1 and 2 to the device 1, so that the device 1 uses these uplink resource information to perform the D2D transmission to the device 2.

In an optional embodiment of the present disclosure, the method further comprises the following steps.

It is detected whether third information transmitted by the first electronic device is received or not by the base station, the third information being used for the first electronic device to notify the base station of stopping to transmit the second transmission resource assignment for the second electronic device to the first electronic device. The base station stops to transmit the uplink transmission resource information allocated for the second electronic device to the first electronic device, when the third information transmitted by the first electronic device is received.

Accordingly, FIG. 4 is a schematic flowchart of the information processing method applied to the first electronic device provided in the second embodiment of the present disclosure, the first electronic device being capable of performing the D2D transmission with the second electronic device. As shown in FIG. 4, the method comprises the following steps.

In a step 401, a first transmission resource assignment for the first electronic device is received for indicating a transmission resource used by the first electronic device in a first transmission.

In a step 402, a second transmission resource assignment for the second electronic device is received for indicating a transmission resource used by the second electronic device in a second transmission as a transmission resource between the second electronic device and a base station.

Here, the device 1 receives the second transmission resource by receiving the uplink transmission resource information allocated to the device 2, which is transmitted by the base station.

It is to be noted that there is no strict order between the

steps

401 and 402, and they may be performed concurrently.

In a step 403, a number of M first attributes of a number of M first transmission sub resource in the first transmission resource assignment are acquired, a number of N second attributes of a number of N second transmission sub resource in the second transmission resource assignment are acquired, and the number of M first attributes are compared with the number of N second attributes to obtain the first detection result.

Here, when the first transmission resource and the second transmission resource are both time frequency resource, the first transmission sub resource and the second transmission sub resource may both be time frequency resource units. The first attribute and the second attribute are time slots of the time frequency resource units. After acquiring the time slot of the time frequency resource unit (the first transmission resource) used in the D2D transmission by the device 1 and the time slot of the time frequency resource unit (the second transmission resource) used in the uplink transmission by the device 2, the two groups of time slots are compared to generate the first detection result.

The process in this step is a detailed process of detecting the first transmission resource assignment and the second transmission resource assignment to generate the first detection result, in the embodiment of the present disclosure.

In a step 404, a number of L first attributes different from the number of N second attributes are determined in the first detection result, and the first transmission sub resource corresponding to the number of L first attributes is selected as the third transmission resource, wherein M and N are positive integers and L is an integer larger than or equal to 0.

In the first transmission resource, the time frequency resource unit corresponding to the time slot different from the time slots of all the time frequency resource units in the second transmission resource assignment is selected as the third transmission resource, that is, the first transmission resource which does not conflict with the second transmission resource assignment is selected as the third transmission resource.

The process in this step is a further process of determining the transmission resource meeting the first predetermined rule among the first transmission resource as the third transmission resource.

In a step 405, the first transmission to the second electronic device is performed with the third transmission resource.

Here, the device 1 uses the third transmission resource which does not conflict with the second transmission resource, to perform the D2D transmission with the device 2 to avoid any transmission conflict between the D2D transmission by the device 1 and the uplink transmission by the device 2, and to make the uplink transmission by the device 2 not be delayed by the D2D transmission by the device 1.

In an optional embodiment of the present disclosure, the step of acquiring a number of M first attributes of a number of M first transmission sub resource in the first transmission resource comprises: determining the first transmission sub resource in the first transmission resource used in a next transmission in the first transmission as a first target sub resource, and acquiring the first attribute of the first target sub resource； and accordingly, the method further comprises: comparing the first attribute of the first target sub resource with the number of N second attribute to determine whether the first attribute of the first target sub resource and the number of N second attribute are at least partially identical, after acquiring a number of N second attributes of a number of N second transmission sub resource in the second transmission resource assignment； selecting the first target sub resource as the third transmission resource when they are not the same； not performing the first transmission to the second electronic device in the first target sub resource when they are at least partially identical. Particularly, when determining which time frequency resource unit to use in the next D2D transmission, the time slot of the time frequency resource unit is determined and it is determined whether the time slot of the time frequency resource unit and the time slots of all the time frequency resource units in the second time frequency resource unit are at least partially identical. If they are all different, the device 1 makes the time frequency resource unit to be the third transmission resource, and uses it to perform the D2D transmission to the device 2. When it is determined that they are at least partially identical, the device 1 does not perform the D2D transmission in this time frequency resource unit.

In another optional embodiment of the present disclosure, the method further comprises: determining whether the first transmission has been finished or not when the first transmission resource assignment, i.e., the D2D transmission resource, has not been exhausted； transmitting, to the base station, third information such as notification information for notifying the base station of stopping to transmit the second transmission resource assignment for the second electronic device to the first electronic device, when the first transmission has been finished； determining whether the first transmission has been finished or not when the first transmission resource assignment has been exhausted； transmitting the first transmission request information to the base station, when the first transmission has not been finished, to request the base station to allocate the D2D transmission resource again, and finishes the D2D transmission according to the above method, such as the steps 401-405, and transmitting the third information to the base station, when the first transmission has been finished.

Accordingly, when the base station detects that the third information such as the notification information is received, it stops to transmit the uplink transmission resource information allocated for the second electronic device to the first electronic device.

It can be seen that in the present embodiment, the D2D transmission resource allocated to the first electronic device by the base station and the uplink transmission resource allocated to the second electronic device by the base station are detected, and the D2D transmission resource which does not conflict with the uplink transmission resource is selected as the transmission resource used for the D2D transmission from the first electronic device to the second electronic device, thereby the conflict between the uplink transmission and the D2D transmission is avoided, so that the uplink transmission and the D2D transmission can be performed normally and the uplink transmission won’t be delayed by the D2D transmission.

In the first embodiment of the base station provided in the present disclosure, the base station can communicate with the first electronic device which may be the cell phone optionally.

FIG. 5 is a schematic diagram of a structure of the base station provided in the first embodiment of the present disclosure. As shown in FIG. 5, the base station comprises a first detecting unit 501 and a first transmitting unit 502.

The first detecting unit 501 detects whether first transmission request information transmitted from the first electronic device is received or not, the first transmission request information being used by the first electronic device for requesting the base station to allocate a first transmission resource for a first transmission as a transmission resource between the first electronic device and a second electronic device, the first transmission request information comprising at least identification information of the second electronic device.

Herein, taking an example in which the first electronic device is a device 1 and the second electronic device is a device 2 supporting the unicast transmission, the first transmission is the D2D transmission between the device 1 and the device 2. The first transmission resource may be a resource block used in the D2D transmission by the device 1, such as the time resource, the frequency resource, or the like. In the present embodiment, the first electronic device described above is the electronic device described in FIG. 6. The first transmitting unit 605 transmits the first transmission request information carrying the ID of the device 2 to the base station after the device 1, particularly the first determining unit 604, determines that the target of the D2D transmission is the device 2. The base station, particularly the first detecting unit 501, detects whether the request is received or not.

The first transmitting unit 502 transmits first response information for the first transmission request information to the first electronic device when the first detecting unit 501 detects that the first transmission request information is received, the first response information comprising at least the first transmission resource assignment indicating transmission resource used by the first electronic device in a first transmission； and second transmission resource assignment for the second electronic device is transmitted to the first electronic device, the second transmission resource assignment indicating a transmission resource used by the second electronic device in a second transmission as a transmission between the second electronic device and the base station.

Herein, the second transmission may be a transmission between the device 2 and the base station, particularly an uplink transmission. The second transmission resource may be the uplink transmission resource used by the device 2.

In the second embodiment of the base station provided in the present disclosure, the base station can communicate with the first electronic device which may be the cell phone optionally.

FIG. 7 is a schematic diagram of a structure of the base station provided in the second embodiment of the present disclosure. As shown in FIG. 7, the base station comprises a first detecting unit 701 and a first transmitting unit 702.

The first detecting unit 701 detects whether first transmission request information transmitted from the first electronic device is received or not, the first transmission request information being used by the first electronic device for requesting the base station to allocate a first transmission resource for a first transmission as a transmission resource between the first electronic device and a second electronic device, the first transmission request information comprising at least identification information of the second electronic device.

Herein, taking an example in which the first electronic device is a device 1 and the second electronic device is a device 2 supporting the unicast transmission, the first transmission is the D2D transmission between the device 1 and the device 2. The first transmission resource may be a resource block used in the D2D transmission by the device 1, such as the time resource, the frequency resource, or the like. In the present embodiment, the first electronic device is the electronic device described in FIG. 8. The device 1, particularly the first transmitting unit 805, transmits the first transmission request information carrying the ID of the device 2 to the base station after the device 1, particularly the first determining unit 804, determines that the target of the D2D transmission is the device 2. The base station, particularly the first detecting unit 701, detects whether the request is received or not.

The first electronic device, particularly the first transmitting unit 805, transmits the first information to a set of the second electronic devices. The set of the second electronic devices is a set of electronic devices in a preset range from the first electronic device. The second information transmitted from the electronic device in the set of the second electronic devices is received by the first electronic device, particularly the first transmitting unit 805, which comprises at least the identification information of the electronic device transmitting the second information. The first electronic device, particularly the first determining unit 804 determines the second electronic device for performing the first transmission with the first electronic device based on the identification information. In particular, the device 1, particularly the first transmitting unit 805, broadcasts the first information ‘discovery’ to the set of the second electronic devices, the device receiving the ‘discovery’ feeds back to the device 1 with its ID, and the electronic device (the second electronic device) which performs the D2D unicast transmission with the device 1 is determined based on the received ID information by the device 1, particularly the first determining unit 804.

The first transmitting unit 702 transmits first response information for the first transmission request information to the first electronic device when the first detecting unit 701 detects that the first transmission request information is received, the first response information comprising at least the first transmission resource assignment indicating transmission resource used by the first electronic device in a first transmission； and second transmission resource assignment for the second electronic device is transmitted to the first electronic device, the second transmission resource assignment indicating a transmission resource used by the second electronic device in a second transmission as a transmission resource between the second electronic device and the base station.

Herein, the second transmission may be a transmission between the device 2 and the base station, particularly an uplink transmission. The second transmission resource may be the uplink transmission resource used by the device 2. After the base station, particularly the first detecting unit 701, has received the first transmission request information, it allocates the D2D transmission resource for the device 1, and notify the first transmitting unit 702 of transmitting the D2D transmission resource allocated for the device 1 and the transmission resource information used by the device 2 in the uplink transmission, to the device 1, particularly the first receiving unit 801 and the second receiving unit 802, so that the device 1 uses these transmission resource information for the D2D transmission to the device 2.

Since the D2D transmission all occurs in the time division duplexed (TDD) uplink resource, after the base station, particularly the first detecting unit 701, has received the first transmission request information transmitted from the device 1, the base station allocates the uplink resource used in the D2D transmission for the device 1, and returns the uplink resource information allocated for the devices 1 and 2 to the device 1 by the first transmitting unit 702, so that the device 1 uses these uplink resource information to perform the D2D transmission to the device 2.

As shown in FIG. 7, the base station further comprises the following units.

A second detecting unit 703 detects whether third information, such as notification information, transmitted by the first electronic device is received or not.

A first stopping unit 704 stops to transmit the uplink transmission resource assignment for the second electronic device to the first electronic device, when the second detecting unit 703 detects that the third information transmitted by the first electronic device is received.

Accordingly, FIG. 8 is a schematic diagram of the electronic device provided in the second embodiment of the present disclosure, the electronic device being capable of performing the first transmission with the second electronic device. As shown in FIG. 8, the electronic device comprises a first receiving unit 801, a second receiving unit 802, a first detecting unit 803, a first determining unit 804 and a first transmitting unit 805.

The first receiving unit 801 receives a first transmission resource assignment for the first electronic device for indicating a transmission resource used by the first electronic device in a first transmission.

Here, the device 1, particularly the first receiving unit 801, receives the first transmission resource assignment by receiving the D2D transmission resource allocated to the device 1 by the base station.

The second receiving unit 802 receives a second transmission resource assignment for the second electronic device for indicating a transmission resource used by the second electronic device in a second transmission as a transmission resource between the second electronic device and a base station.

Here, the device 1, particularly the second receiving unit 802, receives the second transmission resource assignment by receiving the uplink transmission resource information allocated to the device 2, which is transmitted by the base station.

The first detecting unit 803 acquires a number of M first attributes of a number of M first transmission sub resource in the first transmission resource assignment, acquires a number of N second attributes of a number of N second transmission sub resource in the second transmission resource assignment, and compares the number of M first attributes with the number of N second attributes to obtain the first detection result.

Here, when the first transmission resource and the second transmission resource are both time frequency resource, the first transmission sub resource and the second transmission sub resource may both be time frequency resource units. The first attribute and the second attribute are time slots of the time frequency resource units. After the first detecting unit 803 acquires the time slots of the time frequency resource unit (the first transmission resource) used by the device 1 in the D2D transmission and the time slots of the time frequency resource unit (the second transmission resource) used by the device 2in the uplink transmission, the two groups of time slots are compared to generate the first detection result.

The above description is a further description to the first detecting unit 803 detecting the first transmission resource assignment and the second transmission resource assignment to generate the first detection result, in the embodiment of the present disclosure.

The first determining unit 804 determines a number of L first attributes different from the number of N second attributes, and selects the first transmission sub resource corresponding to the number of L first attributes as the third transmission resource, n the first detection result, wherein M and N are positive integers and L is an integer larger than or equal to 0.

In the first transmission resource, the first determining unit 804 selects the time frequency resource unit corresponding to the time slot different from the time slots of all the time frequency resource units in the second transmission resource as the third transmission resource, that is, selects the first transmission resource which does not conflict with the second transmission resource as the third transmission resource.

The above description is a further description to the first determining unit 804 determining the transmission resource meeting the first predetermined rule among the first transmission resource assignment as the third transmission resource in the first detection result generated by the first detecting unit 803.

The first transmitting unit 805 performs the first transmission to the second electronic device with the third transmission resource.

Here, the device 1, particularly the first transmitting unit 805, uses the third transmission resource which does not conflict with the second transmission resource, to perform the D2D transmission with the device 2 to avoid any conflict between the D2D transmission of the device 1 and the uplink transmission of the device 2, and to make the uplink transmission not be delayed by the D2D transmission.

In an optional embodiment of the present disclosure, the first detecting unit 803 is further used for determining the first transmission sub resource in the first transmission resource assignment used in a next transmission in the first transmission as a first target sub resource, and acquiring the first attribute of the first target sub resource； and comparing the first attribute of the first target sub resource with the number of N second attribute to determine whether the first attribute of the first target sub resource and the number of N second attribute are at least partially identical, after acquiring a number of N second attributes of a number of N second transmission sub resource in the second transmission resource assignment； transmitting a first trigger signal to the first determining unit 804 when they are different； transmitting a second trigger signal to the first determining unit 804 when they are at least partially identical. Accordingly, the first determining unit 804 is used for selecting the first target sub resource as the third transmission resource when receiving the first trigger signal, and notifying the first transmitting unit 805 of not performing the first transmission to the second electronic device on the fist target sub source when receiving the second trigger signal. Particularly, when the first detecting unit 803 determines which time frequency resource unit to use in the next D2D transmission, the time slot of the time frequency resource unit is determined and it is determined whether the time slot of the time frequency resource unit and the time slots of all the time frequency resource units in the second time frequency resource unit are at least partially identical. If they are all different, the first trigger signal is transmitted to the first determining unit 804, and the first determining unit 804 makes the time frequency resource unit be the third transmission resource, and notifies the first transmitting unit 805 of using it to perform the D2D transmission to the device 2. When the first detecting unit 803 determines that they are at least partially identical, the second trigger signal is transmitted to the first determining unit 804. The first determining unit 804 notifies the first transmitting unit 805 of not performing the D2D transmission in this time frequency resource unit.

In another optional embodiment of the present disclosure, as shown in FIG. 8, the electronic device further comprises: a first determining unit 806 for determining whether the first transmission has been finished or not when the first transmission resource assignment, i.e., the D2D transmission resource, has not been exhausted； a first transmitting unit 805 for transmitting, to the base station, third information such as notification information for notifying the base station of stopping to transmit the second transmission resource assignment for the second electronic device to the first electronic device, when the first transmission has been finished； a second determining unit 807 for determining whether the first transmission has been finished or not when the first transmission resource assignment i.e., the D2D transmission resource, has been exhausted； a first transmitting unit 805 for transmitting the first transmission request information to the base station, when the first transmission has not been finished, to request the base station to allocate the D2D transmission resource again, and transmitting the third information to the base station, when the first transmission has been finished.

Accordingly, when the base station, particularly the second detecting unit 703, detects that the third information such the notification information is received, the first stopping unit 704 stops to transmit the uplink transmission resource allocated for the second electronic device to the first electronic device.
