Technical field

The present application relates to the field of communications technologies, and in particular, to a method, device, device, and system for identifying a user equipment in an unauthorized transmission.

Background technique

Existing cellular communication systems, such as Global System for Mobile Communication (GSM), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), etc. In the system, the supported communications are primarily for voice and data communications. In general, a traditional base station (BS) supports a limited number of connections and is easy to implement. It should be noted that in LTE (4G, 4th generation mobile communication system), the base station can be called a 4G base station (eNodeB, eNB); in the next generation (5G, fifth generation) mobile communication system (also called new) A new radio (NR) base station may be referred to as a 5G base station (gNodeB, gNB).

The next-generation mobile communication system will not only support traditional communication, but also support massive machine type communication (mMTC) and Ultra-Reliable and Low Latency Communications (URLLC) to meet different services. Demand. For the URLLC service, not only the transmission delay is required, but also the requirement is reliable, such as a vehicle to vehicle (V2V). If the transmission is not reliable, it will cause retransmission.

In the LTE system, when the user equipment (User Equipment, UE) has uplink (UL) data to be transmitted, the UE may first send a Scheduling Request (SR) command to notify the base station of the amount of data to be transmitted. After receiving the SR command, the base station sends the first uplink scheduling message to the UE; the UE sends a Buffer Status Report (BSR) according to the first uplink scheduling message, such as the expected data transmission amount; and then, the base station according to the BSR The second uplink scheduling message is sent to the UE, and then the UE can send the uplink data according to the indication of the second uplink scheduling message. This transmission method is a transmission method based on Grant-based (also referred to as UL Transmission with grant). Generally, the UE may have a delay of more than 10 ms from the time the SR command is sent to actually send the uplink data. For future network systems, such delay cannot meet the low delay requirement.

Compared to traditional authorization-based transmission methods, next-generation wireless communication networks introduce non-authorization (Grant-free, also known as Grantless, or Grant-less, or UL Transmission without grant, or configuration). The transmission method of the configured (autonomous UL transmission, etc.), that is, the base station first divides one or more pieces of resources for unauthorized transmission for the UE (Grant-free resources, which may also be called GFRC, Grant) -free resource, Grantless resource, resource for UL transmission without grant, etc., because the resource used for unauthorized transmission uses Physical UL Shared Channel (PUSCH) resources, so The resources for unlicensed transmission may also be referred to as GF-PUSCH resources, that is, physical uplink shared channels that can be used for unlicensed transmission. Specifically, the UE directly sends the uplink data (such as the uplink Grant-free data) in the resource for the unlicensed transmission, and does not need to go through the uplink authorization process that the UE sends the SR command to the base station to send the uplink scheduling message to the UE. Therefore, it has great advantages in network delay and signaling overhead. In addition, the base station in the NR can also configure multiple resources for unlicensed transmission for the UE. As shown in FIG. 1 , the base station can allocate different unlicensed transmission resources, such as GFRC1 and GFRC2, to the UE in the frequency domain. Different business needs, while blanks can be used for authorized transfers. In FIG. 1, the MCS may indicate a transmission rate (including a modulation order and the like) used by a UE configured by the base station to the UE to transmit uplink data in the corresponding unlicensed transmission resource, and a Transmission Block Size (TBS) 1 may be used. The size of the uplink data sent by the UE configured by the base station to the UE in GFRC1, and the TBS2 may indicate the size of the uplink data sent by the UE configured by the base station to the UE in GFRC2. It should be noted that the time-frequency domain resources (depending on MCS and TBS) actually used by the UE in GFRC1 and GFRC2 may be smaller than the time-frequency domain resources of GFRC1 and GFRC2.

At present, it has been determined in the NR that different UEs can be identified by the frequency of the Grant-free resource and the Demodulation Reference Signal (DMRS) parameter. For example, in GFRC1, the DMRS parameter 1 corresponds to UE1. DMRS parameter 2 corresponds to UE2, and so on. Specifically, when the UE performs the uplink data transmission, the DMRS is sent to the base station in the DMRS resource region to which the uplink data is mapped, to help the base station demodulate the uplink data sent by the UE. Here, the UE generates a DMRS using DMRS parameters. At present, the total number of DMRS parameters is limited, and the theoretical upper limit is 12, that is, at most one of the Grant-free resources carries 12 UEs that correspond one-to-one with the DMRS parameters. In practice, in order to maintain orthogonality between DMRS parameters, the number of DMRS parameters actually available in a Grant-free resource is usually less than 12, such as 4 or 6.

Therefore, in the prior art, there is a problem that the number of UEs that are in one-to-one correspondence with the DMRS parameters in the Grant-free resource is small.

Detailed ways

The method, device, device and system for identifying a user equipment in an unauthorized transmission provided by the embodiments of the present application can be applied to a scenario of unauthorized transmission. As shown in FIG. 2, the application architecture of the embodiment of the present application may include a first user equipment and a network device, and the first user equipment is in communication connection with the network device. Among them, the network device can configure resources for unauthorized transmission. The first user equipment may use the resources configured by the network device for unauthorized transmission for unauthorized transmission.

The first user equipment may include, but is not limited to, an Internet device such as a smart phone (such as an Android mobile phone, an IOS mobile phone, etc.), a personal computer, a tablet computer, a palmtop computer, a mobile internet device (MID), or a wearable smart device. Wait.

The network device may include a base station, which may be a base transceiver station (BTS) in a GSM or system, or an NB (NodeB) in a WCDMA system, or an evolved base station in LTE ( Evolved NodeB, eNB), or a relay station, or an in-vehicle device, a wearable device, and an access network device in a future 5G network or an access network device in a publicly evolved public land mobile network (PLMN) network, etc. This application is not limited.

The technical solutions of the present application are described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in some embodiments.

FIG. 3 is a flowchart of Embodiment 1 of a method for identifying a user equipment in an unauthorized transmission according to an embodiment of the present disclosure. As shown in FIG. 3, the method in this embodiment may include:

Step 301: The first user equipment generates, according to the first DMRS parameter set corresponding to the first user equipment, a DMRS corresponding to each of the K first messages that are repeatedly transmitted.

In this step, the first DMRS parameter set indicates that the first user equipment generates DMRS on each resource when performing repeated transmission on each resource of the resource for unauthorized transmission at L. a DMRS parameter, each DMRS parameter corresponding to one of the resources at the L, wherein each of the resources at the L has a different frequency, L is an integer greater than 1, and K is greater than or An integer equal to L. It should be noted that, the time domain of each resource of the L resource in the embodiment may be different, or may be the same or partially the same, which is not limited in this application. The time domain of the same resource is not limited in this application. For example, the time domain of the same resource may be continuous or discontinuous.

Specifically, when configuring the resource for unauthorized transmission, the network device may configure multiple frequency domain information for the unlicensed transmission resource, and each frequency domain information may be used to indicate a resource for unauthorized transmission. Frequency Range. Optionally, each frequency domain information may have corresponding time domain information, where the time domain information may be used to indicate a time range of resources used for unauthorized transmission. The resource for unlicensed transmission corresponding to the same frequency domain information may be considered as a resource for unauthorized transmission. As shown in Figure 1, GFRC1 can be considered as a resource for unlicensed transmission, and GFRC2 can be considered as another resource for unauthorized transmission. It should be noted that the network device may separately notify multiple user resources for unauthorized transmission through multiple pieces of configuration information, or may notify multiple user resources for unauthorized transmission through a configuration information. This application does not limit this. As shown in FIG. 4, Grant-free resource 1 can be considered as a resource for unauthorized transmission, and Grant-free resource 2 can be considered as another resource for unauthorized transmission.

The repeated transmission may specifically refer to repeated transmission of a physical layer. In the unlicensed transmission, different user equipments can be directly sent in the Grant-free resource when there is uplink data. When the different user equipments send the uplink data, the time-frequency domain resources (assuming that the multiple access method is not considered) are all or When partially overlapping, a collision may be sent and the uplink transmission may fail. Therefore, the user equipment in the unlicensed transmission can improve the transmission reliability of the uplink data by repeating the transmission (K-repetition), that is, the uplink data is repeatedly transmitted in the Grant-free resource multiple times, such as 4 times (K=4). Specifically, the repeated transmission of the uplink data comprises at least two types, one for the initial transmission (1 ^st transmission) of the uplink data remaining the same repeated transmission data other than the initial uplink transmission scenario, only the base station successfully demodulated multiple times The uplink data may be obtained by any one of the uplink data that is repeatedly transmitted; the other is that the uplink data of the initial transmission is completely different or partially different from the uplink data of the repeated transmissions other than the initial transmission, and the uplink data transmission is reliable at this time. The performance is mainly obtained by the base station to perform Soft Combining on the received uplink data of multiple repeated transmissions (also referred to as Incremental Redundancy). The soft combining is that the receiving end (for example, the user equipment or the network device) receives the data packet that cannot be correctly decoded, and the receiving end saves the received error data packet in a buffer and performs subsequent retransmission with the received packet. The data is combined to obtain a more reliable packet than the individual decoding, and then the receiver decodes the combined packet.

It should be noted that the K first messages repeatedly transmitted may be in one-to-one correspondence with the uplink data of the K times of repeated transmissions, and the K first messages repeatedly transmitted are used to carry the uplink data of the K times of repeated transmissions. It is assumed that the number of the first message repeatedly transmitted by the first user equipment in the Grant-free resources at the first to the Lth can be respectively recorded as K1, K2, ..., KL, then K1+K2+...+KL=K, And K1, K2, ..., KL are positive integers.

Alternatively, the number K of repeated transmissions may be greater than or equal to L. When K is equal to L, a repeated transmission is performed in each of the resources for unauthorized transmission at L for each of the resources for unauthorized transmission. When K is greater than L, at least one of the resources for unauthorized transmission at L is repeatedly transmitted in the resource for unauthorized transmission. It should be noted that, when performing multiple repeated transmissions in a resource for unauthorized transmission, the uplink data transmitted repeatedly needs to send the corresponding DMRS, and the DMRS parameters used by the transmitted DMRS are repeatedly transmitted each time. All the same.

Optionally, the first DMRS parameter set may include L elements, and the L elements are in one-to-one correspondence with resources for unauthorized transmission at the L, and each of the L elements indicates the The first user equipment will perform DMRS parameters used in the repeated transmission to generate the DMRS on the corresponding resource at the L. It should be noted that the first DMRS parameter set may specifically include a parameter value of the DMRS parameter, or may also include an identifier corresponding to the parameter value of the DMRS parameter, which is not limited in this application.

It should be noted that the first DMRS parameter set may also be referred to as a first DMRS parameter index set, and other names may be used. The present application does not limit this, as long as the functions are the same. For the specific form of the first DMRS parameter set, the application is not limited. For example, when the first DMRS parameter set is {identity of Grant-free resource 1, identifier of Grant-free resource 2, identity of Grant-free resource 3; DMRS parameter 1, DMRS parameter 2, DMRS parameter 3}, it can be represented The DMRS parameter 1 is used when generating the DMRS on the Grant-free resource 1, the DMRS parameter 2 is used when the DMRS is generated on the Grant-free resource 2, and the DMRS parameter 3 is used when the DMRS is generated on the Grant-free resource 3.

It should be noted that a first message may correspond to one or more DMRSs, which is not limited in this application. For example, when a first message is carried in a time domain transmission unit, and only one DMRS is sent in the time domain transmission unit, the first message may correspond to one DMRS. When a first message is carried in a time domain transmission unit, and the multiple DMRSs are sent in the time domain transmission unit, the first message may correspond to multiple DMRSs. When a first message is carried in multiple time domain transmission units, the first message may correspond to multiple DMRSs. The time domain transmission unit may refer to one time slot, or one micro time slot, or several OFDM symbols, or several time slots, or one subframe.

It should be noted that, in the resources used by the first user equipment for unauthorized transmission at the L, the DMRS parameters used for repeated transmission on the same resource are the same. The DMRS parameters used by the first user equipment for repeated transmission on each of the resources for unlicensed transmission at L may be different, or all the same, or partially identical. Optionally, the DMRS parameters corresponding to each of the first messages of the K first messages are the same; or the DMRS parameters corresponding to each of the first messages of the K first messages are different; or, The DMRS parameters corresponding to each of the first messages in the first message in a message are the same, and the DMRS parameters corresponding to each of the first messages in the first message are different.

Optionally, the first user equipment generates a parameter value of the DMRS parameter used by the DMRS on each resource when performing repeated transmission in each of the Grant-free resources in the Grant-free resource at the L (or, The identification of the parameter values can be combined into a first DMRS parameter set to form a multi-dimensional user equipment identification index set, such as

Taking L=2, and the two resources for unauthorized transmission are Grant-free resource 1 and Grant-free resource 2 respectively, the first DMRS parameter set may be

among them,

The DMRS parameter used by the first user equipment to generate the DMRS when performing repeated transmission on the Grant-free resource 1 may be indicated.

The DMRS parameters used by the DMRS to generate the DMRS when the first user equipment performs repeated transmission on the Grant-free resource 2 may be indicated. Here, the multi-dimensional means that the frequency domain locations of the unlicensed resources used by the user equipment are different.

It should be noted that the specific manner for the first user equipment to determine the first DMRS parameter set is not limited in this application. For example, the first user equipment may be directly allocated to the first user equipment by using the first DMRS parameter set; or the first user equipment may be configured by the network equipment to configure a plurality of first DMRS parameter sets that may be used, and then through a specific index. Instructing to use which first DMRS parameter set in the plurality of first DMRS parameter sets, the process may be embodied in a tabular form; or may be generated by the first user equipment according to preset information, eg, a device number of the user equipment; .

It should be noted that the relationship between the number of DMRS parameters and L is not limited in this application.

Step 302: The first user equipment repeatedly transmits the K first messages to the network device and sends the DMRSs corresponding to the K first messages respectively on the resources at the L.

In this step, the DMRS corresponding to the K first messages is used by the network device to identify that the user equipment that sends the first message is the first user equipment. Specifically, the first user equipment may send the DMRS corresponding to the K first messages repeatedly transmitted to the network device together with the K first messages. The first DMRS parameter set delivered by the network device received by the first user equipment in the first message is

For example, the first message of K1 and K2 repeated transmissions is sent in the Grant-free resource 1 and the Grant-free resource 2 respectively, and the first message of the K1 sent by the first user equipment in the Grant-free resource 1 and use

The generated DMRS corresponding to the first message of the K1, the first message of the K2 sent by the first user equipment in the Grant-free resource 2, and the use

The generated DMRS corresponding to the K2 first message respectively.

It should be noted that, the specific sending manner of the first user equipment on a Grant-free resource is not limited in this application. For example, the first user equipment may adopt a frequency hopping transmission mode, or may not adopt a frequency hopping transmission mode, and whether the frequency hopping is used herein is determined by the configuration of the base station. Assuming that the bandwidth of a Grant-free resource is 2 MHz, the first user equipment adopts a frequency hopping transmission method, for example, in the Grant-free resource, the first frequency of the 1 MHz resource is used first, and the frequency of the larger frequency is 1 MHz. Resources.

It should be noted that, for the specific relationship between step 301 and step 302, the application is not limited, and only needs to ensure that the first message is repeatedly transmitted on a resource in the resource for unauthorized transmission at L. The DMRS corresponding to the first message repeatedly transmitted on the resource may be used.

It should be noted that, when the first user equipment repeatedly transmits the K first message to the network device in the Grant-free resource at the L, the specific time may be repeated transmission to the network device at the same time of the Grant-free resource at the L. K first messages, for example, as shown in FIG. 1, GFRC1 and GFRC2 corresponding to time unit n repeatedly transmit K first messages to the network device. Alternatively, the K first message may be repeatedly transmitted to the network device at different time resources of the Grant-free resource at L. For example, as shown in FIG. 1, the GFRC2 corresponding to the time unit n corresponds to the time unit n+1. GFRC1 repeatedly transmits K first messages to the network device, or GFRC1 and GFRC2 corresponding to time unit n, and GFRC1 corresponding to time unit n+1 repeatedly transmits K first messages to the network device. When the K first message is repeatedly transmitted to the network device at different time resources of the Grant-free resource at the L, the network device and the first user device may agree on a time resource allocation manner.

Step 303: The network device parses the received DMRS corresponding to the K first messages, and parses out the DMRS parameters corresponding to the K first messages.

In this step, optionally, the DMRS corresponding to a first message may be one or more, and the number of DMRSs corresponding to each first message in the K first messages may be different, or all the same or partially the same . Optionally, when the number of DMRSs corresponding to each of the first messages in the K first message is one, the number of DMRS parameters corresponding to the first message parsed in step 303 and the K The number of DMRSs corresponding to the first message may be the same. When the number of the DMRSs corresponding to the first message in the K first message is multiple, the number of the DMRS parameters corresponding to the first message may be smaller than the corresponding one of the K first messages. The number of DMRS.

Step 304: The network device identifies, according to the parsed DMRS parameter, a correspondence between the first user equipment and the first DMRS parameter set, that the user equipment that sends the first message is the first User equipment.

In this step, optionally, the network device identifies, according to the parsed DMRS parameter, a pre-known correspondence between the first user equipment and the first DMRS parameter set, that the user equipment that sends the first message is The first user equipment. Optionally, the network device may identify the DMRS parameter according to the user equipment that is sent by the first user equipment, and may form a DMRS parameter set.

Among them, the DMRS parameter set

Determining, by the first user equipment, DMRS parameters respectively used by the DMRS on each resource when performing repeated transmission on the resources at the L. Further optionally, when the network device obtains the DMRS parameter set according to the parsed DMRS parameter

The first DMRS parameter set that should be used with the first user equipment

When matching, the network device can identify that the user equipment that sends the first message is the first user equipment. The DMRS parameter set that the first user equipment should use (that is, the first DMRS parameter set corresponding to the first user equipment)

The representation may be represented by a correspondence between the first user equipment and the first DMRS parameter set. It should be noted that the DMRS parameter set obtained according to the parsed DMRS parameter is matched with the first DMRS parameter set that the first user equipment should use, and can be specifically understood as indicating that the DMRS parameter set obtained according to the parsed DMRS parameter is The DMRS parameters used by the DMRS when performing repeated transmissions on each of the resources at the L are repeated with each resource at the L indicated by the first DMRS parameter set that the first user equipment should use. The DMRS parameters used to generate the DMRS during transmission are the same. For example, the DMRS parameter set obtained by the network device according to the parsed DMRS parameters is the same as the first DMRS parameter set that the first user equipment should use.

When the network device receives the first message and the corresponding DMRS sent by the same user equipment in each Grant-free resource in the Grant-free resource at the L, the network device can directly identify according to the obtained DMRS parameter set. The user equipment that sent the first message. In one example, the network device configures two Grant-free resources to the user equipment for unauthorized transmission, where the user equipment 1 can be at the first Grant-free resource (such as Grant-free resource 1) and the second place Grant The -free resource (such as Grant-free resource 2) sends the first message of K1 and K2 respectively, and assumes that the network device determines that the DMRS parameter set that user equipment 1 should use is {1, 4}. If the parameter value of the DMRS parameter that the network device resolves in the Grant-free resource 1 is "1", and the parameter value of the DMRS parameter that is parsed in the Grant-free resource 2 is "4", that is, the DMRS obtained by the network device. The parameter set is {1, 4}, and the network device can determine that the obtained DMRS parameter set matches the DMRS parameter set that the user equipment 1 should use, thereby determining that the first message is sent by the user equipment 1.

When the network device receives the first message and the corresponding DMRS that are repeatedly transmitted by the multiple user equipments in each Grant-free in the Grant-free resource at the L, the network device may determine, according to the obtained DMRS parameter set, Sending user equipments of different first transmission corresponding to the first message respectively. It is assumed that the network device can configure two Grant-free resources (such as Grant-free resource 1 and Grant-free resource 2) to multiple user devices for unauthorized transmission. In an example, as shown in FIG. 5A, the DMRS parameter set that should be used by multiple user equipments (such as UE1, UE2, ..., UE8) may be: UE1={1,3}, UE2={2,4} , UE3 = {3, 1}, UE4 = {4, 2}, UE5 = {2, 3}, UE6 = {3, 4}, UE7 = {4, 1}, UE8 = {1, 2}. When the network device parses multiple DMRS parameters in the same Grant-free resource, if the parameter values of the DMRS parameters parsed by the network device in the Grant-free resource 1 are "1" and "3", the network device may The DMRS parameter set that the multiple user equipments should use respectively determines that the DMRS corresponding to the parameter value “1” in the Grant-free resource 1 may be sent by the UE1 or the UE8, and the DMRS corresponding to the parameter value “3” may be sent by the UE3 or the UE6. . Further, assuming that the parameter values of the DMRS parameters parsed by the network device in the Grant-free resource 2 are "3" and "4", the network device may determine the DMRS parameter set according to the DMRS parameter set that the multiple user equipments should respectively use. 1,3} corresponds to UE1, DMRS parameter set {3, 4} corresponds to UE6, that is, DMRS with parameter value "1" in Grant-free resource 1, and the first message corresponding to the DMRS is sent by UE1, Grant-free resource 1 The DMRS of the parameter value “3” and the first message corresponding to the DMRS are sent by the UE6, the DMRS of the parameter value “3” in the Grant-free resource 2, and the first message corresponding to the DMRS are sent by the UE1, and the Grant-free resource 2 is used. The DMRS of the parameter value "4" and the first message corresponding to the DMRS are transmitted by the UE 6.

When the network device receives the first message and the corresponding DMRS that are repeatedly transmitted by the multiple user equipments in each Grant-free in the Grant-free resource at the L, the network device may perform according to the obtained DMRS parameter set and The number of user equipments that are repeatedly transmitted, and the user equipment that sends the first message corresponding to the different repeated transmissions is determined. It is assumed that the network device can configure two Grant-free resources (such as Grant-free resource 1 and Grant-free resource 2) to multiple user devices for unauthorized transmission. In another example, as shown in FIG. 5A, the DMRS parameter set that should be used by multiple user equipments (such as UE1, UE2, ..., UE8) may be: UE1={1,3}, UE2={2,4} , UE3 = {3, 1}, UE4 = {4, 2}, UE5 = {2, 3}, UE6 = {3, 4}, UE7 = {4, 1}, UE8 = {1, 2}. When the network device resolves multiple DMRS parameters in the same Grant-free resource, the parameter values of the DMRS parameters parsed by the network device in Grant-free resource 1 are "1" and "2", but in Grant-free. The parameter values of the DMRS parameters parsed in the resource 2 are “2” and “3”, and the network device may determine that the first message may be sent by the UE1, the UE5, and the UE8 according to the DMRS parameter set that the multiple user equipments should use respectively. Further, if the first message that the network device resolves in a Grant-free resource is sent by two user equipments, the network device may determine that the first message is sent by the UE5 and the UE8. If the first message parsed by the network device in one of the Grant-free resources is sent by three user equipments, the network device may determine that the first message is sent by UE1, UE5, and UE8.

When the first DMRS parameter set is allocated by the network device to the first user equipment, the step 301 may further include: the network device sending a second message to the first user equipment, where the second message indicates The first DMRS parameter set corresponding to the first user equipment. Correspondingly, the first user equipment receives the second message sent by the network device. Optionally, the second message may be semi-static signaling or dynamic signaling. Specifically, the second message may be a master information block (MIB), a system information block (SIB), a radio resource control (RRC) signaling, a physical layer control message, Media Access Control Control Element (MAC CE) signaling, Minimum Residual System Information (RMSI) or Other System Information (OSI). The physical layer control message may specifically be L1 signaling, Downlink Control Information (DCI), group common DCI, and the like. It should be noted that, the specific manner in which the second message indicates the first DMRS parameter set is not limited in this application. For example, the second message may include the first DMRS parameter set, or include an identifier of the first DMRS parameter set, and the like.

It can be seen that, when the network device obtains the corresponding DMRS parameter in the Grant-free resource at the L to match the first DMRS parameter set corresponding to the first user equipment, the first message is sent by the first user equipment, and The larger the L, the higher the complexity and the lower the efficiency. Therefore, from the perspective of complexity, efficiency, and the number of user equipments carried in Grant-free resources, L can be equal to 2.

Optionally, the foregoing DMRS parameters may include: Cyclic Shift.

Step 305: The network device sends a response message to the first user equipment.

In this step, the response message may be used to indicate a positive response or a negative response to the first user equipment. Optionally, when the network device successfully demodulates any second message sent by the user equipment, the network device may send an ACK (Acknowledge) to the first user equipment, to determine that the second is successfully received. a message: when the network device successfully obtains the DMRS parameter but fails to demodulate the K second message, the network device may send a NACK (Negative Acknowledge) to the first user equipment to determine that the network device is not successfully received. Said K second message.

The affirmative response may be a positive response sent by the network device for a certain user equipment (such as UE specific DCI), or may be an affirmation indicated in a response message (such as a Group Common DCI) sent by the network device for multiple user equipments. response. Alternatively, the network device may also indicate a positive response to the first user equipment by not sending a response message to the first user equipment. For example, the first user equipment starts a timer after sending the first message. If the scheduling message from the network device is not received before the timer expires, the user equipment considers that the first message is successfully sent, and the network device may indicate a positive response to the first user equipment by using other methods, which is not limited herein.

The negative response may be a negative response sent by the network device to a user equipment, such as a scheduling message or a scheduling message indicating that the network device is not successfully demodulated to the second message, or the network device is targeting multiple user equipments. The network device can also indicate a negative response to the first user equipment in other manners, which is not limited herein.

It should be noted that step 305 is an optional step.

In this embodiment, the DMRS is generated by using the DMRS on each resource when the first user equipment performs repeated transmission according to the resource indicating that the first user equipment uses the resource for unauthorized transmission at the L. a first DMRS parameter set of the DMRS parameter, the DMRS is generated, the first user equipment repeatedly transmits the K first message to the network device on the resource at the L, and the sending corresponds to the K first message respectively DMRS, the network device parses the received DMRS corresponding to the K first messages, and parses out the DMRS parameters corresponding to the K first messages, and according to the parsed DMRS parameters, Determining a correspondence between the first user equipment and the first DMRS parameter set, identifying that the user equipment that sends the first message is the first user equipment, and implementing the DMRS received according to each resource at the L The corresponding DMRS parameters (which can be understood as multi-dimensional DMRS parameters, the DMRS parameters corresponding to the DMRS received on each resource can be regarded as one-dimensional DMRS parameters) to identify the user equipment, and are received on only one resource. Compared with the user equipment corresponding to the DMRS parameters, the DMRS parameter of the DMRS improves the number of user equipments that can be identified, thereby increasing the number of user equipments carried in the resources for unauthorized transmission. For example, when the parameter value of the DMRS parameter can take any one of four possible values of “1”, “2”, “3”, and “4”, and L is equal to 2, the prior art adopts different When the frequency hopping mechanism between the frequency domain resources is used, the user equipment can directly identify one DMRS parameter in each frequency domain resource, so at most 4*1=4 user equipments can be identified, as shown in FIG. 5B. UE4, 4 user equipments; and the identification method provided in this embodiment can identify at most 4*4=16 user equipments, such as UE1-UE16 and 16 user equipments in FIG. 5C, thereby improving the capability of Grant-free resources. The number of UEs carried.

In addition, as shown in FIG. 6, if the resources used by the user equipment for repeated transmission (such as U1/U2/U3/U4) are less differentiated in the frequency domain (ie, the frequency bands are similar), the frequency is fading due to repeated transmissions. Similar characteristics may result in multiple duplicate transmissions. In the embodiment of the present application, uplink data of multiple repeated transmissions sent by the user equipment may be discretely opened at a larger interval in the frequency domain, as shown in FIG. 7 , the first time (1 ^st ) and the second time of UE1 (2 ^nd ) K-repetition can be performed in Grant-free resource 1, and the third (3 ^rd ) and fourth (4 ^th ) retransmission can be performed in Grant-free resource 2 to obtain Frequency diversity gain, which in turn improves transmission reliability.

It should be noted that, in the first embodiment of the method for identifying the user equipment in the unlicensed transmission, the message that the first user equipment repeatedly transmits is recorded as the first message, and the network device is sent to the first user equipment. The message indicating the first DMRS parameter set is recorded as the second message. In the second embodiment of the method for identifying the user equipment in the unlicensed transmission, the message indicating the first DMRS parameter set by the network device to the first user equipment is recorded as the first message, and the first user is used according to the order in which the messages appear. The message that the device repeatedly transmits is recorded as the second message.

FIG. 8 is a flowchart of Embodiment 2 of a method for identifying a user equipment in an unauthorized transmission according to an embodiment of the present disclosure. As shown in FIG. 8, the method in this embodiment may include:

Step 101: The network device sends a first message to the user equipment to indicate a DMRS parameter index set used by the user equipment to perform repeated transmission in multiple Grant-free resources, for the network device to identify the user equipment.

In this step, the user equipment can be understood as the foregoing first user equipment, and the DMRS parameter index set can be understood as the foregoing first DMRS parameter set, where the plurality of locations can be understood as L, and L is an integer greater than 1. A Grant-free resource is a resource used for unauthorized transmission. Specifically, in the unlicensed transmission, when the user equipment can send the repeatedly transmitted uplink data in the Grant-free resource at the L, the network device may be the Grant of the user equipment in the Grant-free resource at the L- The corresponding DMRS parameters are configured in the free resource, and the corresponding DMRS parameters in each of the Grant-free resources in the Grant-free resource at the L can be combined into a first DMRS parameter set to form a multi-dimensional user equipment identification index set. ,Such as

For example, the network device can configure two Grant-free resources (ie, L=2, such as Grant-free resource 1 and Grant-free resource 2) used by the user equipment to send the repeatedly transmitted uplink data, and the network device sends the user equipment to the user equipment. The first message sent indicates that the first DMRS parameter set may be

among them

The DMRS parameter used by the corresponding DMRS when the user equipment sends the uplink data in the Grant-free resource 1.

The DMRS parameter used by the corresponding DMRS when the user equipment will send the uplink data in the Grant-free resource 2.

It should be noted that the specific description of the repeated transmission can be referred to the first embodiment of the foregoing method, and details are not described herein again. For a specific description of the manner in which the network device sends the first message to the user equipment, refer to the related description of the second message in the first embodiment of the foregoing method, and details are not described herein again.

Step 110: The user equipment sends a second message to the network device, where the second message is uplink data of the retransmission of the unauthorized transmission.

In this step, specifically, the user equipment repeatedly transmits K second messages to the network device and sends DMRSs respectively corresponding to the K second messages on each resource at the L. It should be noted that, in a specific manner that the user equipment repeatedly transmits the K second messages to the network device and the DMRSs corresponding to the K second messages respectively in the Grant-free resource at the L, refer to the foregoing method embodiment 1 In the step 301 and the step 302, the first user equipment repeatedly transmits the K first message to the network device in the Grant-free resource at the L, and sends a related description of the DMRS corresponding to the K first message respectively. Narration.

Step 111: The network device receives the second message, and determines, by using the obtained DMRS parameter index set, that the second message is sent by the user equipment.

In this step, specifically, the network device parses the received DMRS corresponding to the K second messages, and parses out the DMRS parameters corresponding to the K second messages, and according to the parsed Determining the DMRS parameter, and the correspondence between the first user equipment and the DMRS parameter set, and identifying that the second message is sent by the user equipment.

And the network device in step 304 parses the DMRS parameters respectively corresponding to the K first messages, and identifies, according to the parsed DMRS parameters, that the user equipment that sends the first message is a related description of the first user equipment, where not Let me repeat.

Step 112: The network device sends a response message to the user equipment.

In this step, the response message may be used to indicate a positive response or a negative response to the user equipment. Optionally, when the network device successfully demodulates any two second messages sent by the user equipment, the network device may send an ACK (Acknowledge) to the user equipment to determine that the second message is successfully received. When the network device successfully obtains the DMRS parameter but fails to demodulate the K second message, the network device may send a NACK (Negative Acknowledge) to the user equipment to determine that the K-strip is not successfully received. Two messages.

The affirmative response may be a positive response sent by the network device for a certain user equipment (such as UE specific DCI), or may be an affirmation indicated in a response message (such as a Group Common DCI) sent by the network device for multiple user equipments. response. Alternatively, the network device may also indicate a positive response to the user equipment by not sending a response message to the user equipment. For example, the user equipment starts a timer after sending the second message, if the timer expires. The user equipment does not receive a scheduling message from the network device, and the user equipment considers that the second message is successfully sent. The network device may also indicate a positive response to the user equipment in other manners, which is not limited herein.

The negative response may be a negative response sent by the network device to a user equipment, such as a scheduling message or a scheduling message indicating that the network device is not successfully demodulated to the second message, or the network device is targeting multiple user equipments. The network device can also indicate a negative response to the user equipment in other manners, which is not limited herein.

It should be noted that step 112 is an optional step.

In this embodiment, the first message is sent to the user equipment by the network device, to indicate the DMRS parameter index set used by the user equipment to perform repeated transmission in the Grant-free resource at the L, for the network device. Identifying the user equipment, where the user equipment sends K second messages in the Grant-free resource at L, and the network device receives the DMRS corresponding to the K second messages respectively according to the Grant-free resource at the L, Obtaining a DMRS parameter index set consisting of DMRS parameters corresponding to the DMRS received by each Grant-free resource, and confirming that the K second message is sent by the user equipment by using the obtained DMRS parameter index set, and implementing the basis according to the L The DMRS parameters corresponding to the DMRS received on each of the resources are used to identify the user equipment, and the number of user equipments carried in the resources for unauthorized transmission is increased.

In the prior art, for a non-authorized transmission in which a slot is a time domain transmission unit (ie, at least one time slot in an uplink data field sent by a user equipment), the user equipment is at least in the time slot. One of the Orthogonal Frequency Division Multiplexing (OFDM) symbols (for example, Orthogonal Frequency Division Multiplexing (OFDM) symbol 3 in FIG. 9) transmits the DMRS; when the base station considers that the user equipment is in a special environment The mobile station may also configure more than one OFDM symbol for the user equipment, such as the OFDM symbol 11 in FIG. 9, and the user equipment may send an additional DMRS (additional DMRS) on the OFDM symbol 11 to better support the user equipment. Mobility. The DMRS parameter configured by the base station is received by the user equipment, and the DMRS sent on the OFDM symbol 3 and the OFDM symbol 11 is generated by using the DMRS parameter.

Hereinafter, based on a scenario in which a plurality of DMRS resources (for example, OFDM symbol 3 and OFDM symbol 11 in FIG. 9) are configured for a user equipment in one time domain transmission unit, identification in unauthorized transmission as shown in FIG. 10 is provided. User device method.

FIG. 10 is a flowchart of Embodiment 3 of a method for identifying a user equipment in an unauthorized transmission according to an embodiment of the present disclosure. As shown in FIG. 10A, the method in this embodiment may include:

Step 1001: The first user equipment generates, according to the L demodulation reference signal DMRS parameters, L DMRSs sent on L DMRS resources in the same time domain transmission unit among the resources used for unauthorized transmission.

In this step, the L DMRS parameters are in one-to-one correspondence with the DMRS resources at the L, and each of the L DMRS parameters is used by the first user equipment to generate the DMRS resource at the L. The DMRS sent on the corresponding resource, L is an integer greater than 1. The time domain transmission unit may refer to one time slot, or one micro time slot, or several OFDM symbols, or several time slots, or one subframe. For example, one time slot in Figure 9 can be considered a time domain transmission unit. As shown in FIG. 9, a time domain transmission unit includes two DMRS resources (ie, L is equal to 2), which are OFDM symbol 3 and OFDM symbol 11, respectively. Correspondingly, the number of DMRS parameters is also 2, such as DMRS parameter 1 and DMRS parameter 2. It is assumed that the one-to-one correspondence between the L DMRS parameters and the DMRS resources at the L is that the DMRS parameter 1 can correspond to the OFDM symbol 3, and the DMRS parameter 2 can correspond to the OFDM symbol 11, and the user equipment can generate the OFDM symbol 3 according to the DMRS parameter 1. DMRS1 generates DMRS2 transmitted on OFDM symbol 11 according to DMRS parameter 2.

It should be noted that, in FIG. 9 , taking one slot including 14 OFDM symbols as an example, the number of OFDM symbols included in one slot may also be other values, for example, 7 OFDM symbols. Different from the foregoing embodiments shown in FIG. 3 and FIG. 8 , in the embodiment, the DMRS resources at the L are all located in the same time domain transmission unit, and the frequencies of the DMRS resources at the L are the same.

It should be noted that the specific manner in which the first user equipment acquires L demodulation parameters corresponding to the DMRS resources at the L is not limited in this application. For example, the first user equipment may be directly allocated to the first user equipment by using the L demodulation parameters that are specifically used with the DMRS resources at the L; or the network equipment may be configured by the network equipment to use the multiple groups and the possible The L demodulation parameters corresponding to the DMRS resources at the L are respectively indicated by the specific index, and the process may be performed in a tabular form; the first user equipment may also be based on the preset information, For example, the device number of the user device is generated; and so on.

Optionally, before the step 1001, the network device sends, to the first user equipment, M pieces of second messages, where the M second messages correspond to the DMRS resources at the L; each second message corresponds to the Determining at least one DMRS resource in the DMRS resource at the L; the M second message is used to indicate a DMRS parameter that the first user equipment can separately use on each DMRS resource of the DMRS resource at the L, M is an integer greater than 0 and less than or equal to L.

Optionally, the second message may be semi-static signaling or dynamic signaling. Specifically, the second message is: a primary information block MIB, a system information block SIB, a radio resource control RRC signaling, a physical layer control message, a media access control control element MAC CE, a minimum remaining system information RMSI, or other system information. OSI.

When M=1, it can be understood that the network device sends the corresponding relationship between the DMRS resource and the DMRS parameter at the L to the first user equipment by using a second message, where the second message is used to indicate the DMRS resource at the L Correspondence relationship of the L DMRS parameters. It should be noted that the specific manner of indicating the correspondence between the DMRS parameters of the L and the L DMRS parameters is not limited by the application.

It should be noted that, in the prior art, there is only one DMRS parameter for one user equipment, and the DMRS parameter is used to generate the DMRS sent on two DMRS resources. However, in the embodiment of the present application, for the user equipment, the DMRS resources in the DMRS resources of the L correspond to one DMRS parameter, and the DMRS parameters sent by the DMRS resources are generated by using the DMRS parameters corresponding to the resources.

Optionally, for the method for identifying the user equipment in the unauthorized transmission provided by the embodiment of the present application, the switch control may be provided. For example, when it is required to be enabled or activated, correspondingly, the first user equipment may generate the L DMRSs according to L DMRS parameters corresponding to the DMRS resources at the L. Deactivating or deactivating when not in use, correspondingly, the first user equipment may not generate the L DMRSs according to L DMRS parameters corresponding to the DMRS resources at the L, For example, L DMRSs are generated according to one DMRS parameter that does not have a corresponding relationship with the DMRS resources. Therefore, optionally, the step 1001 may further include: the network device sending a third message to the first user equipment, where the third message is used to indicate that the first user equipment is configured according to the DMRS resource at the L A corresponding DMRS parameter generates the L DMRSs. Here, the third device is sent by the network device to the first user equipment to instruct the first user equipment to generate the L DMRSs according to the L DMRS parameters corresponding to the DMRS resources at the L, and the flexibility can be improved.

Step 1002: The first user equipment sends a first message to the network device in the same time domain transmission unit, and sends the foregoing information corresponding to the first message to the network device on the DMRS resource at the L. L DMRSs.

In this step, the L DMRSs are respectively sent on the corresponding resources in the DMRS resources at the L, and the L DMRSs are used by the network device to identify that the user equipment that sends the first message is the First user device. The first message can be a message. The L DMRSs are used to demodulate the first message. For example, the first user equipment uses one slot as a time domain transmission unit, and the first user equipment may send DMRS1 in OFDM symbol 3 in the same time domain transmission unit, and send DMRS2 on OFDM symbol 11. And transmitting the first message on other OFDM symbols than OFDM symbol 3 and OFDM symbol 11.

Step 1003: The network device identifies, according to the DMRS parameter corresponding to the DMRS received on each resource of the DMRS resource at the L, that the user equipment that sends the first message is the first user equipment.

In this step, optionally, the network device is configured according to the DMRS parameter corresponding to the DMRS received on each resource of the DMRS resource at the L, and each of the DMRS resources of the different user equipment at the L that are known in advance. The DMRS parameter corresponding to the DMRS is sent on the resource, and the user equipment that sends the first message is identified as the first user equipment. Specifically, when the network device determines the DMRS parameter corresponding to the DMRS received on each resource at the L, and the DMRS parameter that the first user equipment should use to send the DMRS on each resource at the L When the same, the user equipment that sends the first message may be determined to be the first user equipment. For example, suppose that the network device knows in advance that the DMRS corresponding to the DMRS parameter 1 transmitted by the user equipment 1 in the OFDM symbol 3, the DMRS corresponding to the DMRS parameter 2 transmitted by the user equipment 1 in the OFDM symbol 11, and the DMRS parameter corresponding to the DMRS transmitted by the user equipment 2 in the OFDM symbol 3. 2. The DMRS sent by the user equipment 2 in the OFDM symbol 11 corresponds to the DMRS parameter 1, and the network device sends the L DMRSs and the L DMRSs to the network device in the same time domain transmission unit. After the corresponding first message, if it is determined that the DMRS corresponding to the DMRS parameter 1 is received on the OFDM symbol 3, and the DMRS received on the OFDM symbol 3 corresponds to the DMRS parameter 2, the user equipment that sends the first message may be determined as the user equipment. If it is determined that the DMRS received on the OFDM symbol 3 corresponds to the DMRS parameter 2, and the DMRS received on the OFDM symbol 3 corresponds to the DMRS parameter 1, the user equipment that sends the first message may be the user equipment 2.

Optionally, after the network device identifies that the user equipment that sends the first message is the first user equipment, the following step 1104 may also be performed.

Step 1004: The network device sends a response message to the first user equipment.

In this step, the response message may be used to indicate a positive response or a negative response to the first user equipment. Optionally, when the network device successfully demodulates the first message sent by the first user equipment, the network device may send an ACK (Acknowledge) to the first user equipment, to determine that the first is successfully received. a message: when the network device successfully obtains the DMRS parameter but fails to demodulate the first message, the network device may send a NACK (Negative Acknowledge) to the first user equipment to determine that the first message is not successfully received. A message.

The affirmative response may be a positive response sent by the network device for a certain user equipment (such as UE specific DCI), or may be an affirmation indicated in a response message (such as a Group Common DCI) sent by the network device for multiple user equipments. response. Alternatively, the network device may also indicate a positive response to the user equipment by not sending a response message to the first user equipment. For example, the first user equipment starts a timer after sending the first message, if If the scheduling message is not received from the network device before the timer expires, the first user equipment considers that the first message is successfully sent, and the network device may indicate a positive response to the first user equipment in other manners, which is not limited herein.

The negative response may be a negative response sent by the network device to a user equipment, such as a scheduling message or a scheduling message indicating that the network device is not successfully demodulated to the first message, or the network device is targeting multiple user equipments. The network device can also indicate a negative response to the first user equipment in other manners, which is not limited herein.

For example, when the parameter value of the DMRS parameter can take any one of four possible values of “1”, “2”, “3”, and “4”, and L is equal to 2, the prior art can only identify at most 4*1=4 user equipments corresponding to the DMRS parameters one by one, such as UE1-UE4 in FIG. 10B, a total of 4 user equipments, and the DMRS parameters used by each UE are {1}, {2}, { 3} and {4}; and the identification method provided in this embodiment can identify at most 4*4=16 user equipments, such as UE1-UE16 in FIG. 10C, a total of 16 user equipments, and DMRS parameters used by each UE respectively. For {1,1},{1,2},{1,3},{1,4},{2,1},{2,2},{2,3},{2,4},{ 3,1,},{3,2},{3,3},{3,4},{4,1,},{4,2},{4,3},{4,4}, thus The number of UEs that can be carried in the Grant-free resource is increased.
