However, the C-RNTI in the current mobile communication technology (e.g. 4G) is 16 bits long, which may cause excessive transmission overhead if each UE carries the C-RNTI for identification in uplink transmission data.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

In the future, a new generation of mobile communication system (for example, a fifth generation mobile communication system 5G) may propose three typical scenarios of enhanced multimedia mobile broadband, low power consumption, large connection, low latency and high reliability. The low-power-consumption large connection aims at the scene of massive Internet of things, the typical data packet size is small in the scene, and the number of users is huge.

For a large number of users, a non-orthogonal multiple access technology is currently being researched. Among them, there are non-orthogonal Multiple Access techniques based on Code domain, including PDMA (Pattern Division Multiple Access), SCMA (Sparse Code Multiple Access), MUSA (Multi-User Shared Access), etc.; there are non-orthogonal Multiple Access techniques based on an interleaver, including IDMA (Interleave Division Multiple Access), IGMA (Interleave-Grid Multiple Access), and the like, and non-orthogonal Multiple Access techniques based on a power domain.

For small data packet transmission, uplink non-scheduling transmission mechanism is currently being studied. Uplink scheduling-free transmission means that dynamic and explicit scheduling grant of network side equipment is not required for transmission of the UE, and multiple UEs can share the same time-frequency resource. The scheduling-free transmission can be used for both orthogonal and non-orthogonal multiple access techniques.

Currently, in the discussion of 3GPP (3rd Generation Partnership Project), a resource for uplink schedule-free transmission is referred to as a Multiple Access resource (MA resource). The MA resources include MA physical resources (multiple access physical resources) and MA signatures (multiple access signatures). Wherein, the MA physical resource refers to a time-frequency resource block used for uplink scheduling-free transmission; the MA signature is to assist the network side device in distinguishing users in multi-user detection. According to different multiple access technologies, the MA signature may comprise at least one of: codebooks, codewords, sequences, interleavers, mapping patterns, demodulation reference signals, preambles, spatial domains, power domains, and the like.

For uplink scheduling-free transmission, one mechanism is that the UE randomly selects an MA resource; another mechanism is that the MA resources of the UE are predetermined or preconfigured by the network side device.

The scheduled transmission mechanism in current mobile communication systems (e.g. fourth generation mobile communication system 4G) can guarantee that only one UE transmits data on a specific time-frequency resource. Because the time-frequency resource is allocated by the network side equipment, the UE does not need to carry the UE identification additionally. For the scheduling-free transmission mechanism, multiple users are supported to share the same MA physical resource, so that the UE cannot be identified by the MA physical resource. On the same MA physical resource, it may happen that multiple UEs select the same MA signature, depending on different schedule-free transmission mechanisms and/or the configuration of the network side device. Therefore, the UE cannot be identified with the MA signature either.

The UE may be a terminal Device such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and the network side Device may be an access network entity such as a base station. It should be noted that, in the embodiment of the present invention, specific types of the UE and the network side device are not limited.

The method for identifying UE of the present invention will be described in detail below based on the uplink scheduling-free transmission mechanism, and it should be noted that each scheme in the following embodiments is only taking the uplink scheduling-free transmission mechanism as an application scenario, but is not limited to taking the uplink scheduling-free transmission mechanism as an application scenario. That is, the various schemes in the following embodiments may also be applied in the context of other data transmission mechanisms.

Referring to fig. 1, fig. 1 is a method for identifying a UE according to an embodiment of the present invention, and as shown in fig. 1, the method includes:

step 101, a UE sends a data packet carrying an identification code of the UE to a network side device in a target MA resource, wherein the identification code of the UE is used to identify the UE in the target MA resource.

In this step, the UE sends a data packet carrying an identification code of the UE to a network side device in a target MA resource, where the identification code of the UE is used to identify the UE in the target MA resource. The UE may determine a target MA resource during uplink non-scheduling transmission, and then determine an identification code that identifies the UE in the target MA resource according to the target MA resource.

The UE may determine the target MA resource by selecting one MA resource from a set of MA resources including one or more UE-level MA resources as the target MA resource. The UE-level MA resource set may be a UE-level MA resource set that the network side device is configured to be accessible to the UE, or may be a UE-level MA resource set that the UE can access, which is determined by the UE according to a preset rule.

The network side equipment can configure a public MA resource set through public information, and then configure a UE level MA resource set for each UE according to preset configuration rules. Wherein the UE-level MA resource set may be the same set as the common MA resource set or may be a subset of the common MA resource set. In some embodiments of the present invention, when the network side device does not configure the UE-level MA resource set for the UE, the UE may determine the UE-level MA resource set that the UE can access according to a preset rule. For example, when the network side device does not configure the UE-level MA resource set for the UE, the UE defaults the common MA resource set of the network side device to the UE-level MA resource set of the UE.

The MA resources include MA physical resources and MA signatures, and the network side device may configure a UE-level MA physical resource set for the UE first, and then configure a UE-level MA signature set supported by the MA physical resources for each MA physical resource in the UE-level MA physical resource set.

For example, referring to fig. 2, fig. 2 is a schematic diagram of an application environment provided by an embodiment of the present invention, as shown in fig. 2, an MA physical resource in a common MA resource set configured by the network side device through a common message includes a MA physical resource A, MA physical resource B, MA physical resource C shown in fig. 2, where a cycle of the MA physical resource a is T1, a cycle of the MA physical resource B is T2, and a cycle of the MA physical resource C is T3. The MA signatures in the common MA resource set are MA signature sets corresponding to the MA physical resource A, MA physical resource B and the MA physical resource C, respectively, and the MA signature sets corresponding to the MA physical resource A, MA physical resource B and the MA physical resource C may be configured by the network side device through a common message, or may be predefined, which is not limited herein. The network side device may configure, for UEa, a UE-level MA resource set including MA physical resource A, MA physical resource B and a UE-level MA signature corresponding to MA physical resource A, B, respectively, and may configure, for UEb, a UE-level MA resource set including MA physical resource B and a UE-level MA signature set corresponding to MA physical resource B. When the network side device does not configure a UE-level MA resource set for UEc, the UEc determines, according to a common message configuration, that the UE-level MA resource set of UEc includes MA signature sets corresponding to MA physical resources A, MA physical resources B, MA physical resources C and MA physical resources A, B, C, respectively.

It can be understood that, the network side device may also configure a UE-level MA signature for the UE first, and then configure a MA physical resource set supported by the MA signature for each MA signature in the UE-level MA signature.

After the UE determines the target MA resource in the MA resource set, the UE may select an identification code of the UE in the target MA resource from a pre-acquired identification code set. The target MA includes a target MA physical resource and a target MA signature. The pre-acquired identification code set may be an identification code set configured for the UE by the network side device. The set of identification codes comprises an identification code of the UE in each MA resource in the UE-level MA resource set.

In this embodiment of the present invention, the set of identification codes is configured for the UE by the network side device and sent to the UE. The set of identification codes includes an identification code identifying the UE in each MA resource in the set of MA resources. The identification code identifying the UE in each MA resource may be an identification code identifying the UE in an MA physical resource of the MA resource; may also be an identification code identifying the UE in an MA signature of the MA resource; the UE may also be identified for an identification code that identifies the UE in an MA physical resource of the MA resource and an MA signature.

After determining the identification code identifying the UE in the target MA resource, the UE may send a data packet carrying the identification code of the UE to the network side device in the MA resource. The data packet includes an identifier of the UE and uplink data transmitted by the UE, and the UE identifier and the uplink data may be channel-coded together or separately. In this embodiment, the UE identifier and the uplink data are separately channel-coded, as shown in fig. 3, so as to avoid a situation that the UE sending the data packet cannot be determined if the network side device cannot correctly decode the data packet.

The network side equipment receives a data packet which is sent by the UE and carries the UE identification code, decodes the data packet after receiving the data packet and sends feedback information to the UE according to the decoding condition of the data packet sent by the UE, the feedback information is used for determining whether the data packet transmitted by the UE is successfully transmitted, the UE can determine whether the transmitted data packet is successfully transmitted according to the feedback information, and if the transmission is not successful, the UE can timely resend the data packet.

The feedback information may include an identification code of the UE transmitting a successful data packet and/or an identification code of the UE transmitting a failed data packet. And the UE receives the feedback information and can determine the transmission condition of the data packet sent by the UE according to the identification code of the UE. For example, in the case that the feedback information only includes the identification code of the UE transmitting the successful data packet, the UE may determine whether the data transmitted by the UE is successfully transmitted by judging whether the identification code of the UE exists in the feedback information.

The feedback information may also include a transmission code of each UE in the plurality of UEs arranged according to the first preset order, where the transmission code is used to determine a transmission condition of each UE, and the transmission condition of the UE includes that data packet transmission is successful, data packet transmission is failed, or an identification code of the UE is not detected. The method prescribes a mapping relation between a plurality of transmission codes and a plurality of different transmission conditions in advance, wherein the transmission codes can be ACK and NACK and respectively correspond to transmission success and transmission failure. The transmission code may also be "001", "010", or "011", which corresponds to successful transmission, failed transmission, and undetected UE identification code, respectively. The UE may obtain a transmission code corresponding to the position according to the position of the UE in the first preset sequence, and then determine a transmission condition of the UE according to the transmission code.

The feedback information may also be data transmission conditions in a plurality of MA resources arranged according to a second preset order, where the data packet transmission condition in each MA resource includes an identification code of a UE transmitting a successful data packet and/or an identification code of a UE transmitting a failed data packet in the MA resource. The MA physical resources in the MA resources may be arranged according to the second preset sequence, and may also be MA signatures in the MA resources.

The following describes the present invention by way of example for three different cases where the UE identification code is an identification code that identifies the UE in an MA physical resource, an identification code that identifies the UE in an MA signature, and an identification code that identifies the UE in an MA physical resource and an MA signature.

For the case that the identification code for identifying the UE in each MA resource is the identification code for identifying the UE in the MA physical resource of the MA resource, at this time, the method identifies the UE in units of MA physical resources, that is, the identification code in the identification code set is the intra-group ID for identifying the UE in each MA physical resource, and the UE can select the identification code in the target MA physical resource (i.e., the intra-group ID of the UE in the target MA physical resource) from the UE identification code set according to the target MA physical resource in the target MA physical resource.

For example, as shown in fig. 2, the MA physical resources in the common MA resource set configured by the network side device include a MA physical resource A, MA physical resource B, MA physical resource C shown in fig. 2, where a cycle of the MA physical resource a is T1, a cycle of the MA physical resource B is T2, and a cycle of the MA physical resource C is T3. The MA signatures in the common MA resource set are MA signature sets corresponding to the MA physical resource A, MA physical resource B and the MA physical resource C, respectively, and the MA signature sets corresponding to the MA physical resource A, MA physical resource B and the MA physical resource C may be configured by the network side device through a common message, or may be predefined, which is not limited herein.

If the MA physical resources included in the MA resource set configured by the network side device for the ue a are MA physical resources a and MA physical resources B, the identification code in the MA physical resource a configured by the network side device for the ue a is "00001", and the identification code in the MA physical resource B is "00001".

The network side device does not configure a UE-level MA physical resource set for the UEb, the default UEb may select all public MA physical resources configured by the network side device, and the network side device configures an identification code "00010" for the UEb, corresponding to all MA physical resources.

The network side device does not configure UEc with a UE-level MA physical resource set, default UEc may select all public MA physical resources configured by the network side device, the network side device configures UEc with an identifier code of "00011" in MA physical resource a, an identifier code of "00011" in MA physical resource B, and an identifier code of "00001" in MA physical resource C.

Assuming that ue a, ue b and ue c all choose to initiate uplink non-scheduled transmission on MA physical resource a at time t1, data packets carrying identification codes "00001", "00010" and "00011" are transmitted, respectively.

And the network side equipment receives and decodes the UE a, the UE b and the UE c respectively, and supposing that the network side equipment successfully decodes the identification codes and the uplink data of the UE a and the UE b, successfully decodes the identification code of UEc and unsuccessfully decodes the uplink data of UEc.

The feedback information sent by the network side device to the UE may be an identification code of the UE transmitting a successful data packet as shown in fig. 4, and the feedback information is an identification code of the UE transmitting a successful data packet (i.e. correctly receiving ACK) (i.e. identification code "00001" of UEa in the MA physical resource a and identification code "00010" of UEb in the MA physical resource a).

The feedback information sent by the network side device to the UE may also be a transmission code of each UE in the multiple UEs arranged according to a first preset order, where the transmission code is used to determine a transmission condition of each UE, and the transmission condition of the UE includes that data packet transmission is successful, data packet transmission is failed, or an identification code of the UE is not detected. The position of each UE feedback information on the feedback message is predefined, as shown in fig. 5, a transmission code "ACK" (indicating that data transmission is successful) is indicated at the position corresponding to the UE a and the UE b, and a transmission code "NACK" (indicating that data transmission is failed) is indicated at the position corresponding to the UEc.

For different ways of identifying the UE, one feedback message may carry feedback messages for multiple MA physical resources, and the position of each MA physical resource feedback information on the feedback message is predefined. Suppose that ue a, ue b, and ue C all choose to initiate uplink schedule-free transmission at time t1, where ue a and ue b choose MA physical resource a, UEc chooses MA physical resource C, and ue a, ue b, and ue C send the identification codes "00001", "00010", and "00001" carried in the data packet, respectively. Assuming that the network side device successfully decodes the identification code and uplink data in the data packet sent by the UE a, the UE b, and the UE c, the feedback information may be the feedback information as shown in fig. 6, where different information fields in the feedback information correspond to the feedback information of different MA physical resources, and the feedback information in the different information fields may be the identification code of the UE that successfully transmits the data packet as shown in fig. 6, or may be the transmission code corresponding to the UE arranged in each information field according to a predetermined sequence.

For the case that the identification code identifying the UE in each MA resource is the identification code identifying the UE in the MA signature of the MA resource, the method identifies the UE in MA signature units.

In the following, taking orthogonal scheduling-free transmission and MA signature as a pilot (specifically, uplink demodulation reference signal) as an example, the method specifies a mapping relationship between the number n of one or more uplink demodulation reference signals and one or more demodulation reference signals in advance. And the network side equipment configures an uplink demodulation reference signal number '1' for the UE a, configures an uplink demodulation reference signal number '2' for the UE b and configures an uplink demodulation reference signal number '3' for the UEc, and when the UE a, the UE b and the UE c all select to initiate uplink scheduling-free transmission at the time of t1, uplink demodulation reference signals corresponding to the uplink demodulation reference signal numbers '1', '2' and '3' are respectively adopted for uplink transmission.

Assuming that the network side device successfully decodes the identification code of the UEa and the uplink data, successfully decodes the identification code of the UEb but not successfully decodes the uplink data of the UEb, and the identification code of UEc is not successfully detected, the network side device may indicate a transmission success message for the identification code "00001" and/or a transmission failure message for the identification code "00010" and/or an undetected identification code message for the identification code "00011" in the feedback message.

For the case that the identification code identifying the UE in each MA resource may also be an identification code identifying the UE in an MA physical resource of the MA resource and an MA signature, the network side device configures a UE and an MA physical resource set for the UE, and configures a corresponding UE-level MA signature set for each MA physical resource in the UE-level MA physical resource set, where the MA signature set includes one or more MA signatures. It should be noted that, the above description is only given by taking the example that the network side device pre-configures the UE-level MA physical resource set for the UE, but the present invention is not limited thereto. That is to say, the network side device may also configure a UE-level MA signature set for the UE first, and then configure a corresponding MA physical resource set for each MA signature in the UE-level MA signature set. The identification code of the UE is now determined by the UE's intra-group ID in MA physical resources and its selected MA signature.

The following description is made by taking PDMA as an example, where the MA signature in this example is a codeword (specifically, a PDMA pattern).

Assume that the method contracts the pattern rectangle for PDMA to be:

each column is a pattern of PDMA, and the number is 0-7. Suppose that a network side device configures multiple MA physical resources as shown in fig. 2 through a common message, the network side device configures, for the UE a, MA physical resources in the UE-level MA resources including MA physical resource a and MA physical resource B, and configures a UE-level signature set including PDMA patterns 0 to 3, that is, the network side device configures multiple MA physical resources as shown in fig. 2, where the MA physical resources include MA physical resource a and MA physical resource B, and configures the UE-level signature set including

The intra-group ID corresponding to each PDMA pattern corresponding to each MA physical resource is "0001".

The network side equipment does not configure a UE level MA physical resource set for the UEb, the default UEb can select all public MA physical resources configured by the network side equipment, and the network side equipment configures the UE level MA signature set for the UEb and contains PDMA patterns 4-7, namely

The network side device configures UEc that MA physical resources in the UE-level MA resource set include MA physical resource a, does not configure a UE-level MA signature corresponding to MA physical resource a for UEc, and defaults to UEc that all PDMA patterns can be selected, where the in-group ID corresponding to each PDMA pattern corresponding to MA physical resource a is "0010".

Suppose that UEa, UEb, UEc all choose to select MA physical resource a to initiate uplink hands-free transmission at time t1, where UEa selects PDMA pattern

Carry intra-group ID "0001"; UEb selects PDMA pattern

Carry intra-group ID "0001"; UEc select PDMA pattern

The intra-group ID "0010" is carried.

Assuming that the network side device successfully decodes the intra-group ID and the uplink data of the ue a and the ue b, successfully decodes UEc the intra-group ID, but unsuccessfully decodes UEc the uplink data, the network side device indicates the intra-group ID or the intra-group ID and the PDMA pattern number in the corresponding feedback message.
