Description

The present invention relates to communication technologies, and in particular, to a method for transmitting a neighboring identity indicator, a user equipment, and a base station. BACKGROUND OF THE INVENTION Proximity discovery is a technology that uses two or more user equipments (User Equipments; hereinafter referred to as UEs) to communicate with each other in physical locations, and has different applications in different scenarios, for example, Proximity discovery can be used in social networking applications to discover nearby friends or people with similar interests; also in the advertising application, to see what discount information is nearby; also in the location-based service, query nearby Information such as restaurants.

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. The embodiments are a part of the embodiments of the invention, and not all of the embodiments. 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.

The method for transmitting a neighboring identity indicator and the method for discovering a neighboring device provided by the embodiment of the present invention may be specifically applied to a process in which a UE performs a neighboring identity indicator transmission process or a UE discovers a proximity when a UE periodically transmits an indication signal. The process of the device. Hereinafter, an embodiment of the present invention will be described in detail by taking a communication system as an example of LTE.

FIG. 1 is a flowchart of an embodiment of a method for transmitting a proximity identity indicator according to the present invention. As shown in FIG. 1 , the method for sending a neighboring identity indicator provided by this embodiment specifically includes the following:

Step 101: The UE obtains the discovery application resource broadcasted by the base station, where the discovery application resource is a resource for requesting the time-frequency resource required for sending a Device to Device code (hereinafter referred to as D2Dcode).

When the UE is in the idle state, the base station broadcasts the discovery application resource to the UE in the coverage of the base station, and the UE receives the discovery application resource sent by the base station, where the discovery application resource is used by the UE to apply for sending the proximity identity indicator. The resource of the frequency resource, usually the proximity identity code is a machine code.

Step 102: The UE requests the base station to send the time-frequency resource required for sending the neighbor identity indicator of the UE by using the discovery resource, and obtains the time-frequency resource allocated by the base station for the UE to send the neighbor identity indicator of the UE. After receiving the discovery application resource sent by the base station, the UE may apply to the base station to send the time-frequency resource required for sending the UE's neighbor identity indicator by discovering the application resource, and obtain the neighbor identity indication allocated by the base station to the UE for sending the UE. The time-frequency resource of the code. For example, the base station may allocate time-frequency resources according to the user level of the UE, the service type, and the information of one or all of the requirements sent by the UE, which is not limited.

Step 103: The UE sends the neighbor identity indicator of the UE on the obtained time-frequency resource.

After the UE receives the time-frequency resource allocated by the base station for transmitting the neighbor identity indicator of the UE, the foregoing method of the UE is applicable to the case where the UE is idle. If it is active, the UE can directly carry one or more bits of information on the Physical Uplink Shared Channel (hereinafter referred to as PUSCH), and the base station can simultaneously share the channel in the physical downlink. The downlink link shared channel (hereinafter referred to as PDSCH) carries an index of the allocated time-frequency resource for transmitting the neighbor identity indicator, or may also send the number of times the neighbor identity indicator is sent.

It should be noted that the time-frequency resource in this embodiment is the same as the time-frequency resource used in the LTE system. Specifically, the time-frequency resource in the LTE system may be periodically divided into a part as a neighboring identity indication. For the resource of the time-frequency resource of the code, for example, the first lms of the 80 ms time-frequency resource may be used as the time-frequency resource for transmitting the neighbor identity indicator. That is to say, this embodiment does not require the operator to separately reserve a dedicated time-frequency resource to transmit the proximity identity indicator, thereby reducing the cost of the operator.

The method for transmitting a neighboring identity indicator code provided by the embodiment of the present invention obtains a discovery application resource broadcasted by the base station by using the UE, where the discovery application resource is a resource for requesting to send a time-frequency resource required for the neighboring identity indicator code; The resource applies to the base station for the time-frequency resource required to send the neighbor identity indicator of the UE, and obtains the time-frequency resource allocated by the base station for the UE to send the neighbor identity indicator of the UE, and then the UE can obtain the time-frequency resource. The neighboring identity indicator of the UE is sent. In the embodiment of the present invention, the time-frequency resource used by the UE to send the neighboring identity indicator is the same as the time-frequency resource in the LTE system, so the operator does not need to reserve a dedicated time-frequency resource separately. To send a proximity identity indicator, which reduces the cost of the operator.

2 is a flow chart of another embodiment of a method for transmitting a proximity identity indicator according to the present invention. As shown in FIG. 2, the execution entity of this embodiment is a UE, and the neighbor identity indicator is sent in this embodiment. The method specifically includes the following:

Step 201: The UE obtains a discovery application resource broadcasted by the base station, where the discovery application resource is a resource for requesting time-frequency resources required for sending the proximity identity indicator.

Step 202: The UE sends a public signature sequence on the time-frequency resource indicated by the application resource. After the UE receives the discovery application resource sent by the base station, the UE may send the public signature to the base station on the time-frequency resource indicated by the discovery application resource. The sequence is determined to determine that the UE that needs to apply for time-frequency resources is a UE that the base station can allocate time-frequency resources.

Specifically, the UE may send a public signature sequence on the time-frequency resource indicated by the discovery application resource, where the public signature sequence may be generated by the UE according to the public signature sequence set generation method carried in the discovery application resource broadcasted by the base station to the UE. The public signature sequence may also be randomly selected by the UE in a common signature sequence set, where the common signature sequence set is a preset sequence of the eNB and the UE; for example, the signature sequence may be a preamble in LTE. It can also be a relatively short sequence similar to the Sounding Reference Signal (SRS).

Step 203: The UE receives the response message sent by the base station. The response message is sent by the base station to the UE after receiving the public signature sequence, and the response message includes a first index of the time-frequency resource allocated by the base station to the UE for transmitting the information of the UE.

After the UE sends the public signature sequence to the base station on the time-frequency resource indicated by the application resource, the UE receives the response message sent by the base station, and the response message may include the time-frequency resource allocated by the base station to the UE for transmitting the information of the UE. An index, the time-frequency resource corresponding to the first index is a time-frequency resource that the base station allocates a neighboring identity indicator for the UE, that is, a time-frequency resource that the base station and the UE perform information transmission. The response message may further include a Temporary Cell Radio Network Temporary Identifier (hereinafter referred to as Temp C-RNTI) and/or a Time Advance value (hereinafter referred to as TA value for short). The Temp C-RNTI can be used in the scrambling process of the information transmission process between the UE and the base station, and the time adjustment value is the time when the UE is away from the base station. The base station can allocate the use of the UE time-frequency resource according to the time when the UE is away from the base station. Number of times or time interval.

Step 204: The UE selects a random number as the temporary identifier of the UE, and sends the information of the UE to the base station on the time-frequency resource corresponding to the first index. The information of the UE includes the temporary identifier of the UE, and may also include the user level of the UE. The UE may select one random number as the temporary identifier of the UE, and the length of the random number may be 32 bits, 40 bits, or 64 bits, etc. The temporary identifier of the UE may be used according to the first 40 bits (or the first 32 bits) or the last 40 bits (or the upper 32 bits) of the neighboring identity indicator from the upper to the lower bits. The UE may determine, according to the correspondence between the first index and the time-frequency resource, the time-frequency resource corresponding to the first index, where the mapping of the corresponding relationship may be set in the correspondence relationship set in the UE, or may be the record correspondence relationship set in the UE end. In the database.

The UE may send the information of the UE to the base station on the time-frequency resource corresponding to the first index, where the information of the UE includes one or all of the temporary identifier of the UE, the user level of the UE, the service type of the UE, and the sending requirement of the UE, where the UE may The user level and service type of the UE are obtained during the registration phase. The user level can be roughly divided into high and low levels, and can be divided into more levels according to network control or charging policies, for example, level 3, level 4 or level 9. The UE's service type may include target class discovery, no target class discovery, and the like. The sending requirements may include: the minimum number of times to be sent on the requested time-frequency resource, the need to send continuously, the time each time needs to be sent, and so on.

Step 205: The UE receives the UE identifier sent by the base station, and receives a second index of the time-frequency resource allocated by the base station to the UE for sending the neighbor identity indicator of the UE.

After the UE sends the information of the UE to the base station, the base station according to the user level of the UE sent by the UE,

The information of the service type of the UE and the transmission requirement of the UE are used to allocate the time-frequency resource and the number of transmissions to the UE, and the UE receives the UE identifier sent by the base station, and the neighboring identity indicator code used by the receiving base station to allocate the UE for transmitting the UE. The second index of the time-frequency resource may also receive the threshold of the number of transmissions of the neighboring identity indicator assigned by the base station to the UE or may also send other information capable of deriving the threshold of the number of transmissions, where the other information is not limited, and the base station is not limited. Send a message confirming that the UE received the information. The time-frequency resource of the neighboring identity indicator of the transmitting UE allocated by the UE is allocated by the second index. The number of times of transmission is the threshold of the number of times that the base station allocates the neighboring identity indicator code on the time-frequency resource allocated by the base station.

Step 206: If the UE determines that the UE identifier sent by the base station is the same as the temporary identifier of the UE, the UE determines that the time-frequency resource corresponding to the second index is the time-frequency resource used for sending the neighbor identity indicator of the UE.

The threshold of the number of transmissions of the proximity identity indicator assigned by the base station to the UE. If no transmission threshold is received, the default is unlimited. The threshold of the number of transmissions is a threshold number of base stations.

Step 306: If the UE determines that the UE identifier sent by the base station is the same as the temporary identifier of the UE, then the time-frequency resource of the neighbor identity indicator of the UE is sent.

After receiving the UE identifier sent by the base station, and receiving the threshold of the number of transmissions of the neighboring identity indicator code allocated by the base station, the UE determines whether the UE identifier sent by the base station and the temporary identifier generated by the UE itself are the same. The time-frequency resource is successful, and the UE obtains the time-frequency resource corresponding to the time-frequency resource index.

Step 307: The UE determines whether the number of times the neighboring identity indicator is saved by the UE is less than or equal to the number of times of sending; if yes, step 308 is performed; if not, the neighbor identity saved by the UE If the number of times the indicator code is sent is greater than the threshold of the number of times of transmission, step 309 is performed.

Step 308: The UE sends the neighbor identity indicator of the UE on the obtained time-frequency resource.
