The technical solutions in the present application are clearly and completely described in the following with reference to the drawings in the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

The D2D technology (that is, the terminal eNB) is a method in which a neighboring UE can directly transmit data through a direct link within a short range, and does not need to be forwarded through a central node (ie, an eNB).

The short-distance communication characteristics and direct communication mode of D2D technology have the following advantages: (1) UE short-distance direct communication can achieve higher data rate, lower delay and lower power consumption; (2) using the network Short-range characteristics of widely distributed UE and D2D communication links, Effective use of spectrum resources can be realized; (3) D2D direct communication can adapt to local data sharing requirements such as wireless P2P services, and provide flexible adaptive data services; (4) D2D direct communication can utilize the number of networks A large and widely distributed UE that expands the coverage of the network.

In the Long Term Evolution (LTE) system, the D2D technology refers to the D2D communication process that is controlled by the LTE system in the LTE licensed band. It fully utilizes the advantages of the D2D technology, and the control of the LTE system can overcome the traditional D2D technology. Some problems, such as uncontrollable interference. In addition, the D2D communication can also be performed on the non-LTE licensed frequency band or without the control of the LTE system. At this time, the D2D communication between the UEs is completed by the autonomous organization, and no base station equipment assists the control.

The D2D communication process includes D2D discovery and D2D communication; the UE discovers other UEs in its vicinity through the D2D discovery signal, and performs data communication after establishing the D2D connection; within the network coverage, the resources used by the D2D discovery signal are notified by the base station device. The transmitting UE and the receiving UE are enabled to enable the transmitting UE and the receiving UE to perform discovery using resources configured by the base station device. In addition, outside the network coverage, the resources used by the D2D discovery signal may also be predefined resources, or may be resources allocated by one of the UEs.

The transmitting end UE sends a D2D discovery signal on the resource configured by the base station device, and the multiple receiving end UEs can simultaneously receive the D2D discovery signal on the resource to discover the transmitting end UE. In addition, the transmitting end UE can also configure the resource in the base station device. On other resources, the D2D discovery signals of other UEs are received. The transmitting UE needs to transmit the D2D discovery signal on one OFDM (Orthogonal Frequency Division Multiplexing) symbol, and needs to receive the D2D discovery signal of other UEs on at least one other OFDM symbol.

Due to the limitation of the radio frequency, the UE needs a certain conversion time (20 us) between transmitting the D2D discovery signal and receiving the D2D discovery signal. Therefore, the transmitting UE sends the OFDM symbol on one OFDM symbol. When the D2D discovery signal is sent, the OFDM symbols on both sides of the OFDM symbol cannot be used to receive the D2D discovery signal of other UEs, but only serve as a guard interval for transceiving and translating.

Whether D2D communication can be performed between the UEs, and then the D2D communication pairing between the transmitting end UE and the receiving end UE is completed. As shown in FIG. 1, the method for transmitting D2D response information includes the following steps: Step 101: A UE (ie, a receiving UE) determines a physical resource occupied by a D2D discovery signal. In the embodiment of the present application, the UE determines the physical resource occupied by the D2D discovery signal, and specifically includes: the UE receives the indication information that the D2D discovery signal from the base station device occupies the physical resource, and uses the indication information to determine the physical resource occupied by the D2D discovery signal; or The UE (the receiving end UE) receives the indication information that the D2D discovery signal from the transmitting end UE occupies the physical resource, and uses the indication information to determine the physical resource occupied by the D2D discovery signal; or, the UE detects whether the physical resource is separately detected on multiple physical resources. A D2D discovery signal is received to determine the physical resources occupied by the D2D discovery signal.

In a specific implementation manner, the base station device needs to configure the physical resource occupied by the transmitting end UE to send the D2D discovery signal, and notify the sending end UE and the receiving end UE of the indication information of the physical resource occupied by the D2D discovery signal; Determining, by the UE, the physical resource occupied by the D2D discovery signal, and then transmitting the D2D discovery signal; The receiving UE determines the physical resource occupied by the D2D discovery signal by using the indication information, and then receives the D2D discovery signal.

In another specific implementation manner, the transmitting end UE may configure the physical resource occupied by the D2D discovery signal, send the D2D discovery signal on the physical resource, and notify the receiving and receiving the indication information of the physical resource occupied by the D2D discovery signal. The UE is used by the receiving end UE to determine the physical resource occupied by the D2D discovery signal, and then receives the D2D discovery signal.

In another specific implementation manner, the base station device needs to configure the physical resource occupied by the transmitting end UE to send the D2D discovery signal, and notify the sending end UE of the indication information of the physical resource occupied by the D2D discovery signal; The indication information determines the physical resource occupied by the D2D discovery signal, and then transmits the D2D discovery signal. Further, the receiving end UE determines whether the D2D discovery signal is received on the plurality of physical resources to determine the physical resource occupied by the D2D discovery signal.

Step 102: The UE receives the D2D discovery signal on the physical resource occupied by the D2D discovery signal. The transmitting end UE needs to send the D2D discovery signal on the physical resource occupied by the D2D discovery signal, and the receiving end UE needs to receive the D2D discovery signal on the physical resource occupied by the D2D discovery signal.

Step 103: The UE generates D2D response information according to the reception result of the D2D discovery signal. In the embodiment of the present application, the D2D response information includes but is not limited to one or any combination of the following:

(1) The identification information of the UE (ie, the transmitting end UE) that sends the D2D discovery signal; the identification information may be an index of all the UEs that the transmitting end UE needs to discover at the receiving end UE, for example, the receiving end UE is configured by the base station device to discover The four-bit information may be used to indicate the identification information corresponding to the four UEs. The identifier information may also be a D2D-dedicated ID configured by the base station device to the transmitting UE, that is, the base station device may be a UE for each transmitting end. Configure the appropriate D2D ID.

(2) whether the UE successfully receives the feedback information of the D2D discovery signal (determined based on the reception result of the D2D discovery signal); for example, by using the identifier 1 to characterize that the UE successfully receives the D2D discovery signal, and uses the identifier 0 to characterize that the UE is unsuccessful Received a D2D discovery signal.

(3) Received power strength information obtained by measuring the D2D discovery signal; for example, after receiving the D2D discovery signal successfully, the receiving UE can obtain received power strength information by measuring the received D2D discovery signal, and the receiving The power strength information is similar to the RSRP (Reference Signal Received Power) information in the existing system.

(4) A request for establishing a D2D communication connection between the UE (ie, the receiving UE) and the UE transmitting the D2D discovery signal (ie, the transmitting UE) needs to be different from the communication connection request of the existing cellular network.

In this embodiment, the D2D response information may include multiple pieces of content, which are multiple content corresponding to one sending end UE, or multiple content corresponding to multiple sending end UEs; for this, when D2D response information The process of generating the D2D response information by the UE includes: the UE generates D2D response information including the content for each content; or, the UE jointly encodes the multiple content, and generates the content for the jointly encoded content. D2D response information of the content; or, the UE performs a concatenation process on the multiple content, and generates D2D response information including the content for the concatenated processed content; wherein, the UE may perform multiple content in the order indicated by the base station device A plurality of contents are subjected to cascading processing in a cascading process or in an order determined based on identification information of the D2D discovery signal.

Step 104: The UE determines the feedback resource occupied by the D2D response information, and sends the D2D response information on the feedback resource, that is, the D2D response information is sent to the base station device or the sending end UE. In the embodiment of the present application, the UE (ie, the receiving UE) determines the feedback resource occupied by the D2D response information, which includes but is not limited to the following manners:

Manner 1: The UE receives the downlink signaling from the base station device for configuring the feedback resource occupied by the D2D response information, and obtains the feedback resource occupied by the D2D response information from the downlink signaling.

In the first mode, the base station device may notify the UE of the feedback resource information occupied by the D2D response information, such as the high layer signaling or the DCI (downlink control information) signaling, by the UE from the high layer signaling or the DCI signaling. The feedback resources occupied by the D2D response information are obtained. For example, if the D2D response information needs to be sent in the manner of a PUCCH (Physical Uplink Control Channel), the base station device can configure the PUCCH resource used by the corresponding PUCCH format by using the high layer signaling; If the Uplink Shared Channel is transmitted in the manner of the physical uplink shared channel, the base station device may indicate the resource occupied by the corresponding PUSCH in the scheduled DCI.

Manner 2: The UE calculates the feedback resource occupied by the D2D response information corresponding to the D2D discovery signal by using the sequence information of the physical resource and/or the physical resource occupied by the D2D discovery signal.

In the second mode, the feedback resource occupied by the L D2D response information may be represented by a resource index n_response. For example, if the n_response can represent the PUCCH resource occupied by the D2D response information, then: the starting position of the physical resource occupied by the n_response and the D2D discovery signal. The sequence identifier of the physical resource occupied by the D2D discovery signal (ie, n_ID) has a corresponding relationship: n_response = f (n_low, n_ID).

For example, n_response=( floor ( n_low/N_dis ) *N_ID +n_ID ) mod N_res; or, n_response= ( round ( n_low/N_dis ) *N_ID +n_ID ) mod N_res; In the above formula, the N_ID represents the same resource Number of sequence multiplexing, said N_dis is the number of PRBs occupied by each D2D discovery signal. The N_res is the total size of the feedback resources occupied by the D2D response information. The floor function is rounded down and the round function is rounded off.

It should be noted that if a D2D discovery signal is received by multiple UEs (receiver UEs) and multiple UEs need to feed back D2D response information, different feedback resources need to be used between the multiple UEs; The UE obtains the starting position of a resource or a resource from the physical resource and/or the sequence information of the physical resource of the D2D discovery signal; that is, n_response is an index of a resource, or represents a starting position of a resource, or a resource. Number, each resource number maps a resource.

Manner 3: The UE obtains the feedback resource occupied by the D2D response information corresponding to the D2D discovery signal by using the resource information carried in the D2D discovery signal.

In the third mode, when the resource information carried in the D2D discovery signal includes the index value n_response of the feedback resource occupied by the D2D response information, the feedback resource occupied by the D2D response information is determined by using the n_response carried in the D2D discovery signal; When the resource information carried in the information includes the starting position of the feedback resource occupied by the D2D response information, the starting position carried in the D2D discovery signal and related information (such as D2D ID) are used to determine the feedback resource occupied by the D2D response information.

In the fourth mode, the UE (ie, the receiving UE) receives the control signaling from the sending UE for configuring the feedback resource occupied by the D2D response information, and obtains the feedback resource occupied by the D2D response information from the control signaling.

In the fourth mode, the transmitting end UE may notify the receiving end UE of the feedback resource information occupied by the D2D response information by using the high layer signaling or the DCI signaling, and the receiving end UE obtains the D2D response from the high layer signaling or the DCI signaling. Feedback resources used by the information. For example, if the D2D response information needs to be sent in the manner of a PUCCH, the transmitting end UE may configure the PUCCH resource used by the corresponding PUCCH format by using the high layer signaling; The information needs to be sent in the manner of the PUSCH, and the transmitting end UE can indicate the resources occupied by the corresponding PUSCH in the scheduling DCI.

In this embodiment, the UE sends the D2D response information corresponding to the D2D discovery signal on the feedback resource, including but not limited to the following:

In a first mode, the UE (ie, the receiving UE) sends the D2D response information corresponding to the D2D discovery signal to the base station device at a time on the feedback resource; that is, the UE sends the D2D response information corresponding to the D2D discovery signal to the base station device. For example, the receiving UE collects the D2D response information corresponding to the D2D discovery signal by using the PUCCH resource after successfully discovering the transmitting UE (ie, the feedback information of the successfully received D2D discovery signal and the measured received power strength). Information) is sent to the base station device.

In the second mode, the UE (ie, the receiving UE) periodically sends the D2D response information corresponding to the D2D discovery signal on the feedback resource until the D2D discovery signal is successfully received (that is, the UE that successfully sends the D2D discovery signal is successfully found); that is, the UE is in the UE. The D2D response information corresponding to the D2D discovery signal is periodically sent to the base station device or the transmitting end UE, until the UE transmitting the D2D discovery signal is successfully found; for example, the UE receives the D2D discovery signal at the physical resource configured by the base station device, If the D2D discovery signal is not successfully received, the D2D response information corresponding to the D2D discovery signal is periodically fed back (ie, the feedback information of the D2D discovery signal is not successfully received), and once the UE successfully receives the D2D discovery signal, the D2D will be successfully received. The feedback information of the discovery signal is sent to the base station device, and the corresponding feedback resource is released.

In the third mode, the UE (ie, the receiving UE) periodically transmits the D2D response information corresponding to the D2D discovery signal on the feedback resource after successfully receiving the D2D discovery signal; that is, the UE periodically responds to the D2D discovery signal on the feedback resource. The D2D response information is sent to the base station device or the transmitting end UE. For example, whether the UE successfully receives the D2D discovery signal, the PUCCH format 2 (format 2) is periodically reported in the PUCCH. D2D response information.

In a fourth mode, the UE (ie, the receiving UE) sends the D2D response information corresponding to the D2D discovery signal on the feedback resource after receiving the response triggering command from the base station device or the transmitting UE; that is, the UE receives the base station device or the sending UE. After the response triggering command, the D2D response information corresponding to the D2D discovery signal is sent to the base station device or the transmitting end UE on the feedback resource; for example, the base station device schedules the PUSCH transmission for transmitting the D2D response information by using the DCI, and the UE passes the indicated PUSCH. The resource feedback D2D response information; or, the base station device triggers the UE to perform layer reporting of the D2D response information by using a specific event, and the UE feeds back the D2D response information after being triggered by the specific event.

In this embodiment, the UE may send the D2D response information through the physical layer signaling on the feedback resource. Alternatively, the UE may send the D2D response information through the high layer signaling on the feedback resource.

In the embodiment of the present application, the base station device needs to receive the D2D response information from the UE on the corresponding feedback resource, and when the base station device learns from the D2D response information that the receiving UE has successfully received the D2D discovery signal of the sending UE, Some or all of the content of the D2D response information is notified to the transmitting end UE; after receiving the notification, the transmitting end UE may stop transmitting the D2D discovery signal.

Thereafter, the UE A determines the indication information by using the indication information. The D2D discovers the physical resources occupied by the signal, and then can transmit the D2D discovery signal; and the UE B uses the indication information to determine the physical resource occupied by the D2D discovery signal, and then can receive the D2D discovery signal.

Step 502: UE A sends a D2D discovery signal on a physical resource occupied by the D2D discovery signal, and UE B receives the D2D discovery signal on a physical resource occupied by the D2D discovery signal.

The base station device may pre-configure a plurality of D2D discovery signal sets by using high layer signaling, and then trigger D2D response information corresponding to one of the D2D discovery signal sets by DCI; or configure only one D2D discovery signal set.

After receiving the trigger signaling of the base station device, the UE B sends the D2D response information corresponding to the D2D discovery signal indicated by the trigger signaling on the PUSCH resource indicated by the corresponding DCI; if the trigger signaling indicates multiple D2D discovery signals, The UE B cascades the D2D response information corresponding to the multiple D2D discovery signals and then reports the information to the base station device.
