Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a data transmission method, related equipment and a readable storage medium. Background Art

[0002] In the existing mechanism, each terminal establishes its own control plane connection and user plane connection with the core network / access network, such as: Non-Access Stratum (NAS) connection of the core network control plane, Radio Resource Control (RRC) connection of the access network control plane, Protocol Data Unit (PDU) session of the core network user plane, Data Radio Bearer (DRB) or Quality of Service (QoS) flow of the access network user plane.

[0070] The embodiments of the present application are described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0071] See also Figure 2 , Figure 2 It is a flowchart of the data transmission method provided in an embodiment of the present application. Figure 2 The data transmission method can be executed by the master terminal. Figure 2 As shown, the following steps may be included:

[0072] Step 201: The master terminal performs a first operation.

[0073] The master terminal is the master terminal among Q terminals, and Q is an integer greater than 1. The Q terminals may include one master terminal and Q-1 auxiliary terminals. The master terminal among the Q terminals may be determined based on at least one of the following: the order of access to the network; the capability of the terminal; the link quality of the terminal. In practical applications, the master terminal among the Q terminals may be changed. For example, in the case where the master terminal is determined based on the link quality of the terminal, assuming that the Q terminals include UE1 and UE2. At a first time point, the link quality of UE1 is higher than the link quality of UE2, then UE1 may be determined as the master terminal at this time; if at a second time point, the link quality of UE2 improves and the link quality of UE2 is higher than the link quality of UE1, then UE2 may be determined as the master terminal at this time.

[0074] In the embodiment of the present application, the Q terminals can support jointly receiving data of the first service, that is, the Q terminals can support jointly receiving data of the same service. In the embodiment of the present application, the Q terminals supporting jointly receiving data of the same service can be regarded as having an associated relationship.

[0075] The Q terminals support jointly receiving data of the first service, which may be specifically manifested as any of the following:

[0076] The types of data of the first service received by the Q terminals are different, that is, different types of data of the first service are transmitted in different terminals, for example, different data streams are transmitted in different terminals. Data streams can be distinguished by QoS flow, and data with the same or similar QoS requirements can be mapped to the same QoS flow. In implementation, different data streams of the first service can be transmitted to the bearers (Radio Bearer, RB) corresponding to different terminals. For example, a user can use UE1 to receive data streams 1 and 2 of the first service, and use UE2 to receive data streams 3 and 4 of the first service.

[0077] The data of the first service received by the Q terminals are of the same type, that is, the same type of data of the first service is divided or copied and transmitted at different terminals, for example, the same data stream is transmitted at different terminals. In implementation, the data of the same RB corresponding to the first service may be divided or copied and transmitted to different terminals. For example, a user can use UE1 and UE2 to receive data streams 1 and 2 of the first service at the same time, and the data of the first service received by UE1 and the data of the first service received by UE2 are the same or different. If they are the same, the data can be detected and deleted for duplication, and if they are different, the received data can be sorted.

[0078] In a specific implementation, the first operation may include at least one of the following:

[0079] Receiving downlink information of a first object sent by a network side device;

[0080] Sending uplink information of the first object to the network side device;

[0081] The first object includes some or all of the Q terminals.

[0082] In the embodiments of the present application, the following situations may be included:

[0083] Case 1: The master terminal only supports the transmission of its own information (the information may include at least one of uplink information and downlink information).

[0084] Case 2: the master terminal at least supports the transmission of information of the first object. In some embodiments, the master terminal may support the transmission of information of the Q terminals.

[0085] It should be noted that in the embodiments of the present application, the main terminal supports the transmission of information of a certain terminal, which does not mean that the information of the terminal must be transmitted through the main terminal. For example: assuming that the main terminal supports the transmission of information of auxiliary terminal a, when auxiliary terminal a has not established an RRC connection with the network side device, the information of auxiliary terminal a can be transmitted through the main terminal agent (that is, the configuration information or reporting information of the auxiliary terminal is carried in the signaling of the main terminal, and the auxiliary terminal does not have its own signaling process); when auxiliary terminal a has established an RRC connection with the network side device, the information of auxiliary terminal a can be directly transmitted through the communication interface between auxiliary terminal a and the network side device, or it can be transferred through the main terminal (also called relay, intermediate transmission or assisted transmission). In addition, the information of the main terminal can also be transferred and transmitted through other auxiliary terminals that establish an RRC connection with the network side device. The specific details can be determined according to the actual situation, and the embodiments of the present application do not limit this.

[0086] For case 1, the communication interface between the master terminal and the network side device is only used to transmit the information of the master terminal, and the first object is the master terminal. The information of each of the Q terminals can be transmitted through the interface between itself and the network side device, that is, the information of the Q terminals can be transmitted independently.

[0087] For situation two, the communication interface between the main terminal and the network side device can transmit the information of some or all of the Q terminals, and the first object may include at least one of the Q terminals. In this case, the information of the auxiliary terminals of the Q terminals can be transmitted through the path between the auxiliary terminal and the main terminal, and the path between the main terminal and the network side device, that is, the information of the auxiliary terminal can be transferred or transmitted by the main terminal. Of course, it can be understood that the information of the auxiliary terminals of the Q terminals can also be transmitted through the communication interface between itself and the network side device, which can be determined according to the actual situation, and the embodiments of the present application do not limit this.

[0088] Optionally, the Q terminals include at least one secondary terminal, and the method may further include:

[0089] The master terminal performs a second operation, where the second operation includes at least one of the following:

[0090] After receiving first downlink information of a first terminal, sending the first downlink information to the first terminal, where the first terminal is any secondary terminal in the first object;

[0091] Before sending the first uplink information of the second terminal, the first uplink information sent by the second terminal is received, where the second terminal is any secondary terminal in the first object.

[0092] In specific implementation, for the downlink information of the auxiliary terminal, the network side device can send it to the main terminal through the communication interface between the main terminal and the network side device, and then the main terminal sends it to the auxiliary terminal through the communication interface between terminals.

[0093] For the uplink information of the auxiliary terminal, the auxiliary terminal may send it to the main terminal through the communication interface between the terminals, and then the main terminal sends it to the network side device through the communication interface between the main terminal and the network side device.

[0094] It should be noted that when the first object includes at least two terminals, the information of each terminal in the first object can be transmitted together or independently between the main terminal and the network side device. The specific information can be determined based on actual conditions, and the embodiments of the present application do not limit this.

[0095] In the data transmission method of this embodiment, the master terminal can transmit only its own information, or it can transmit the information of Q terminals that support the common reception of the first service. It can be seen that the network side device can configure an aggregated bearer or an independent bearer for the Q terminals, so that the Q terminals can realize the common reception of the same service under the control of the network side device, thereby improving the autonomy of the Q terminals in receiving the same service together, and further improving the service experience and system efficiency.

[0096] In the embodiment of the present application, optionally, the downlink information may include but is not limited to at least one of the following: timing advance (TA); cell-radio network temporary identifier (C-RNTI); resource scheduling information. Further, the resource scheduling information may include at least one of the following: dynamic resource scheduling information; semi-static resource scheduling information.

[0097] Optionally, the uplink information may include, but is not limited to, at least one of the following: physical layer control information; media access control (MAC) layer control information; hybrid automatic repeat request (HARQ) feedback information. Further, the MAC layer control information may include at least one of the following MAC control elements (CE): buffer status report (BSR); power headroom report (PHR); recommended bit rate (Recommended Bit Rate).

[0098] In an embodiment of the present application, for timers of control information, such as BSR retransmission timer, BSR cycle timer, etc., the timers of each terminal can be maintained separately based on each UE, that is, each UE maintains its own; or they can be maintained uniformly by the master terminal.

[0099] For different information, the information transmission method may be different, as described below:

[0100] 1. The downlink information includes TA.

[0101] In this case, the network side device can send the downlink information through a competitive random access process, or through a non-competitive random access process. In other words, the secondary terminal can obtain its own TA through a competitive random access process, or through a non-competitive random access process.

[0102] Furthermore, the downlink information may also include C-RNTI, that is, C-RNTI may also be sent through a random access process. Of course, in some embodiments, C-RNTI may also be sent through dedicated signaling.

[0103] In the case where the downlink information of the secondary terminal is sent through a competitive random access process, after the secondary terminal establishes an RRC connection with the network side device, it can send the identification information of the primary terminal to the network side device through the communication interface between itself and the network side device. In this way, the network side device can know the association relationship between the primary terminal and the secondary terminal, and then construct a first architecture for the common transmission of the Q terminals.

[0104] The first architecture of the embodiment of the present application can be understood as being similar to an inverted dual connection (DC) architecture, because the DC architecture is used for data transmission between one terminal and two network-side devices, while the first architecture is used for data transmission between Q terminals and one network-side device. In addition, since the first architecture includes multiple terminals and is used for common transmission of multiple terminals, the first architecture can also be called a multi-UE architecture or a multi-UE common transmission architecture.

[0105] In the case where the downlink information of the secondary terminal is sent through a non-contention access process, the method may further include:

[0106] After establishing an RRC connection with the network side device, the master terminal receives first information sent by the network side device, where the first information includes a dedicated random access resource of the third terminal;

[0107] The main terminal sends the first information to the third terminal;

[0108] The third terminal includes at least one auxiliary terminal among the Q terminals.

[0109] In this embodiment, after establishing an RRC connection with the main terminal, the network side device may send at least one dedicated random access resource to the main terminal. The main terminal may send the at least one dedicated random access resource to the auxiliary terminal. At least one auxiliary terminal among the Q terminals may use the dedicated random access resource allocated by the network side device to initiate a non-competitive random access process to obtain a TA. In this case, since the auxiliary terminal uses the dedicated random access resource allocated by the network side device to initiate a non-competitive random access process to obtain a TA, the network side may know the association relationship between the main terminal and the auxiliary terminals of the second part, and then construct a first architecture for the common transmission of the Q terminals.

[0110] Furthermore, the network side device may also send the C-RNTI together with the dedicated random access resource, so that the secondary terminal can receive the dedicated random access resource and the C-RNTI through one message.

[0111] It should be noted that in the embodiment of the present application, different terminals can share the same TA and / or C-RNTI. For example, assuming that the Q terminals include UE1 and UE2, UE1 is the primary terminal, UE2 is the secondary terminal, and UE1 and UE2 are close to each other, it can be considered that the TAs of the two terminals are consistent, UE2 can directly use the TA of UE1, UE2 does not need RACH, and the network side device can directly establish a dual UE architecture.

[0112] 2. The downlink information includes resource scheduling information.

[0113] In this case, the resource scheduling information of each terminal can be transmitted independently or through the master terminal. That is to say, the resource scheduling information of each terminal can be applicable to the aforementioned situation one or the aforementioned situation two.

[0114] In the case where the resource scheduling information of each terminal is transmitted through the master terminal, optionally, the resource scheduling information of each terminal in the first object is determined by any one of the following: indicated by the downlink information; allocated by the master terminal; negotiated by the first object.

[0115] In the scenario where the resource scheduling information of each terminal in the first object is indicated by the downlink information, the network side device can carry the resource scheduling information of each terminal and the identification information of the terminal corresponding to each resource scheduling information in the downlink information. In this way, after receiving the downlink information, the primary terminal can know the resource scheduling information of each terminal and forward the respective resource scheduling information to each secondary terminal.

[0116] In the case where the resource scheduling information of each terminal in the first object is allocated by the master terminal, the network side device only allocates the resource scheduling information of the Q terminals, but does not indicate the resource scheduling information corresponding to each terminal. After receiving the downlink information, the master terminal can determine the resource scheduling information of each terminal by itself and forward the respective resource scheduling information to each auxiliary terminal.

[0117] In the case where the resource scheduling information of each terminal in the first object is negotiated by the first object, the network side device only allocates the resource scheduling information of the Q terminals, but does not indicate the resource scheduling information corresponding to each terminal. After receiving the downlink information, the master terminal can forward the downlink information to each terminal, and each terminal negotiates to determine its corresponding resource scheduling information.

[0118] It should be noted that the above implementation manner may be applicable to dynamic resource scheduling information and / or semi-static resource scheduling information.

[0119] For dynamic resource scheduling information, considering the high timeliness requirement, the dynamic resource scheduling information of each terminal can be transmitted independently.

[0120] For semi-static resource scheduling information, allocation and activation of semi-static resources, semi-static resource scheduling information can be divided into two types. One is that the RRC signaling directly indicates information such as the time-frequency resource location and period, and the UE can use it directly without any activation. The other is that the RRC signaling only indicates the period information, and the time-frequency resource location information also needs to monitor the Physical Downlink Control Channel (PDCCH) scheduling or activation.

[0121] For the former, the semi-static resource scheduling information of each terminal can be transmitted independently or through the master terminal.

[0122] For the latter, the period information of each terminal can be transmitted independently or through the master terminal, and the time-frequency resource location information of each terminal can be transmitted independently to increase the activation rate of semi-static resources.

[0123] In an embodiment of the present application, semi-static resources can be temporarily transferred between terminals.

[0124] Optionally, when the downlink information includes resource scheduling information, and the resource scheduling information is semi-static resource scheduling information, after the master terminal performs the first operation, the method further includes:

[0125] The master terminal receives third information sent by the fifth terminal, where the third information indicates that the first semi-static resource of the fifth terminal is in an idle state;

[0126] The master terminal transmits fourth information through the first semi-static resource, where the fourth information includes identification information of the master terminal and data of the master terminal;

[0127] The fifth terminal is any auxiliary terminal among the Q terminals.

[0128] In this implementation manner, the fifth terminal has no data to send or receive on its own first semi-static resources, and can transfer the first semi-static resources to other terminals for use through interaction between terminals, thereby improving resource utilization.

[0129] In specific implementation, transmitting the fourth information may specifically include at least one of the following: sending the information of the main terminal; receiving the information of the main terminal. In order to facilitate the receiver of the fourth information to know which terminal the fourth information specifically belongs to, the identification information of the terminal may be carried in the fourth information.

[0130] Optionally, when the downlink information includes resource scheduling information, and the resource scheduling information is semi-static resource scheduling information, after the master terminal performs the first operation, the method further includes:

[0131] The master terminal sends fifth information to the sixth terminal, where the fifth information indicates that the second semi-static resource of the master terminal is in an idle state;

[0132] The sixth terminal includes at least one auxiliary terminal among the Q terminals.

[0133] In this implementation manner, the master terminal has no data to send or receive on its own second semi-static resources, and can transfer the second semi-static resources to other terminals for use through interaction between terminals, thereby improving resource utilization.

[0134] In the embodiment of the present application, in the first implementation mode, the network side device can allocate Q first uplink dedicated resources to the Q terminals, and the Q first uplink dedicated resources correspond to the Q terminals one by one. That is, the network side device allocates an independent uplink dedicated resource to each terminal for reporting uplink information.

[0135] In this implementation, uplink information of each terminal can be transmitted independently, and uplink information of the auxiliary terminal can be sent by the auxiliary terminal to the network side device through the uplink dedicated resource corresponding to the auxiliary terminal. The first object is part or all of the Q terminals.

[0136] In the second implementation mode, the network side device may allocate a second uplink dedicated resource to the master terminal of the Q terminals, and the second uplink dedicated resource corresponds to the Q terminals. In other words, the network side device may allocate and send all the uplink dedicated resources of the Q terminals to the master terminal, and the master terminal assists in reporting uplink information for other auxiliary terminals.

[0137] In this implementation, the uplink information of the auxiliary terminal can be transferred or transmitted by the main terminal, and after being sent to the main terminal, the main terminal sends the uplink information of the auxiliary terminal to the network side device through the uplink dedicated resource corresponding to the main terminal. The first object is the main terminal.

[0138] During implementation, the uplink dedicated resources may include at least one of the following: uplink dedicated scheduling request (Dedicated-Scheduling Request, D-SR) D-SR resources, physical uplink control channel (Physical Uplink Control Channel, PUCCH) resources.

[0139] Optionally, the master terminal sends uplink information of the first object to the network side device, including any of the following:

[0140] 1) The master terminal sends uplink information of a fourth terminal to a network side device at a first time-frequency resource position, where the first time-frequency resource position corresponds to the fourth terminal, and the fourth terminal is any terminal in the first object;

[0141] 2) The master terminal sends second information to the network side device, where the second information includes at least one uplink information and identification information of the terminal corresponding to the at least one uplink information.

[0142] In this embodiment, the main terminal can transmit the information of the auxiliary terminal, and the terminal can send the information of the auxiliary terminal in mode 1) or 2) to facilitate the network side device to distinguish the information of each terminal, thereby improving the effectiveness of information transmission. It can be understood that for downlink information, when the network side device sends the downlink information of each terminal, it can also send the downlink information in the same way as sending the uplink information, so as to facilitate the main terminal to distinguish the information of each terminal, thereby improving the effectiveness of information transmission.

[0143] In 1), different time domain resource positions can be allocated to different terminals, and the information of each terminal can be transmitted at the corresponding time domain resource position. In this way, the network side device or the main terminal can determine which terminal the information belongs to based on the time domain resource position corresponding to the received information.

[0144] In 2), the signaling carrying the terminal information also carries the terminal identification information. In this way, after receiving the signaling, the network side device or the terminal can determine which terminal the information in the signaling belongs to based on the terminal identification information carried in the signaling.

[0145] It should be noted that in 2), the information of multiple terminals can be sent in cascade or independently, which can be determined according to actual conditions and is not limited in this embodiment of the present application.

[0146] See also Figure 3 , Figure 3 It is a flowchart of the data transmission method provided in an embodiment of the present application. Figure 3 The data transmission method is executed by the auxiliary terminal. Figure 3 As shown, the data transmission method may include the following steps:

[0152] In the case where the second object is a network-side device, the information of each terminal is transmitted independently, and the information of each terminal can be transmitted through the interface between itself and the network-side device.

[0153] When the second object is the main terminal, the information of each terminal can be transmitted through the main terminal, and the information of the auxiliary terminal is transferred or transmitted through the main terminal, that is, the information of the auxiliary terminal is transmitted through the path between the auxiliary terminal and the main terminal, and the path between the main terminal and the network side device.

[0154] In the data transmission method of this embodiment, the information of the auxiliary terminal can be transmitted by itself, or can be transferred or transmitted by the main terminal. It can be seen that the network side device can configure an aggregated bearer or an independent bearer for the Q terminals, so that the Q terminals can receive the same service together under the control of the network side device, thereby improving the autonomy of the Q terminals to receive the same service together, and further improving the service experience and system efficiency.

[0172] The auxiliary terminal transmits seventh information through the third semi-static resource, where the seventh information includes identification information of the auxiliary terminal and data of the auxiliary terminal;

[0173] The seventh terminal is any terminal among the Q terminals except the auxiliary terminal.

[0174] In this implementation, the auxiliary terminal can use the semi-static resources of other auxiliary terminals or the main terminal to send and receive data when the semi-static resources of other auxiliary terminals or the main terminal are in an idle state, thereby improving resource utilization.

[0175] Optionally, when the downlink information includes resource scheduling information, and the resource scheduling information is semi-static resource scheduling information, after the secondary terminal performs the third operation, the method further includes:

[0176] The auxiliary terminal sends eighth information to an eighth terminal, where the eighth information indicates that the fourth semi-static resource of the auxiliary terminal is in an idle state, and the eighth terminal is any terminal among the Q terminals except the auxiliary terminal.

[0177] In this implementation manner, the auxiliary terminal may transfer its own idle semi-static resources to other auxiliary terminals or the main terminal for data transmission and reception, thereby improving resource utilization.

[0179] See also Figure 4 , Figure 4 It is a flowchart of the data transmission method provided in an embodiment of the present application. Figure 4 The data transmission method is executed by the network side device. Figure 4 As shown, the data transmission method may include the following steps:

[0186] When the third object and the fourth object are the same object, the information of each terminal is transmitted independently, and the information of each terminal can be transmitted through the interface between itself and the network side device. It should be noted that when the fourth object includes two or more terminals, the information of each terminal in the fourth object can be sent simultaneously or successively.

[0210] It should be noted that this embodiment is Figure 2The embodiments of the network side device corresponding to the method embodiments can therefore be found in Figure 2 The relevant descriptions in the method embodiment can achieve the same beneficial effects. In order to avoid repeated descriptions, they will not be repeated here.

[0211] In the embodiment of the present application, the Xth terminal (such as the first terminal to the eleventh terminal) can be any terminal of the Q terminals. In practical applications, different Xth auxiliary terminals can be the same auxiliary terminal or different auxiliary terminals, which can be determined according to actual conditions, and the embodiment of the present application does not limit this.

[0212] The various optional implementation modes introduced in the embodiments of the present application may be implemented in combination with each other or may be implemented separately, and the embodiments of the present application are not limited to this.

[0213] For ease of understanding, the following examples are provided:

[0214] This application mainly solves the problem of common transmission of services between two or more devices, and may include the following contents:

[0215] The TA and / or C-RNTI of the second UE may be obtained by the second UE initiating a normal contention-based random access process to the network to obtain the TA and C-RNTI, and the second UE or the first UE may report or request the association of the two UEs; or, a dedicated random access resource and / or a second C-RNTI may be obtained from the network via the first UE, and the second UE may use a dedicated random access process to obtain the TA from the network;

[0216] The physical layer transmissions of the two UEs are scheduled using different C-RNTIs, and the HARQ feedback is also independent of each other, according to the existing HARQ feedback mechanism; if it is a semi-static resource, it can be configured to a specific UE or designated for use by a specific UE during configuration;

[0217] The transmission of uplink physical layer or MAC layer control information can be performed by the first UE, and different UEIDs can be distinguished, or the two UEs can each transmit control information in the uplink.

[0218] The following is described in conjunction with embodiments:

[0219] Embodiment 1: TA acquisition.

[0220] TA is information that every UE with data transmission needs to obtain in order to perform uplink synchronous transmission, such as uplink HARQ feedback of uplink data or downlink data. The purpose of uplink synchronous transmission is to align the signals of different UEs when arriving at the base station, so as to better meet the orthogonality and improve the reception success rate.

[0221] For the architecture where two UEs jointly receive the same or related data, the base station needs to establish an architecture similar to inverted DC (Dual Connectivity) for the two UEs. The reason for inverted DC is that traditional DC is that one UE is connected to two gNBs for data transmission, while the requirement of this case is that two UEs are simultaneously connected to one gNB for data split transmission. The data of different bearers (Radio Bearers, RBs) can be transmitted separately in different UEs, or the data of the same RB can be split / copied and transmitted in two UEs.

[0222] Due to the different distances between the two UEs, the two UEs need to maintain their own TA and / or C-RNTI. The first UE to access the network is called the primary UE or the first UE. It first establishes an RRC connection with the network according to the existing process and obtains TA or TA+C-RNTI information through the existing contention-based random access process. The UE that accesses the network later is called the secondary UE or the second UE. It obtains TA or TA+C-RNTI in the following two ways:

[0223] The first one is that the second UE also autonomously initiates an access process to the network, uses the existing contention-based random access process, obtains TA or TA+C-RNTI information, and carries the association relationship between itself and the first UE in the RRC signaling, so that the base station can configure subsequent independent (separate) DRB or split DRB architecture for the two connected UEs.

[0224] The second type is that the first UE requests the establishment of a multi-UE architecture during the RRC signaling interaction with the base station. After the base station accepts the request, it will send a dedicated random access resource or a dedicated random access resource + a second C-RNTI to the first UE, such as a dedicated Preamble code or a dedicated time-frequency resource position, etc. The first UE forwards the dedicated random access resource information to the second UE through the interface between UEs. The second UE uses the dedicated random access resource to initiate a non-competitive random access process to the network, thereby obtaining TA or TA+C-RNTI information.

[0225] Through the above two methods, the use of C-RNTI and TA between UEs and the association relationship between them for the multi-UE architecture are established between the base station and the two UEs, and this information can be used for data transmission in the multi-UE architecture later.

[0226] It should be noted that, in this embodiment, two UEs are used as examples, but the same method can also be applied to the case of more UEs, that is, when there are two or more second UEs, they can also independently compete for random access to the network to obtain TA or TA+C-RNTI and then inform the network of the association relationship, or the first UE can apply to the network for multiple sets of dedicated random access resources, which are allocated to multiple second UEs for non-competitive random access process to obtain TA or TA+C-RNTI.

[0227] Here, the reason why there is a description like TA or TA+C-RNTI is mainly because TA must be obtained through a random access process, and C-RNTI can be obtained by a random access process or can also be obtained by dedicated signaling allocation. The two can be obtained together or separately.

[0228] Embodiment 2: Uplink control information transmission.

[0229] There are two modeling methods for uplink information transmission:

[0230] Mode 1: The two UEs are independent from the perspective of L2 / L1, and their respective L2 / L1 processes fully reuse existing UE behaviors;

[0231] Mode 2: The master UE is responsible for L2 / L1 uplink transmission and distinguishes UE ID during transmission.

[0232] There are two reasons for the existence of mode 2. One is that the transmission power of other UEs may be limited or they may not be able to complete uplink transmission well for the purpose of power saving. The other is the convenience of design and maintenance. Only one UE uplink is seen from the network side.

[0233] For mode 1, the two UEs are independently configured with uplink dedicated resources, such as uplink D-SR resources, PUCCH resources, etc., for their respective uplink transmissions, and the two UEs independently perform uplink transmissions according to their own needs. From the MAC layer, the transmission of various MACCEs, such as BSR (Buffer Status Report), PHR (Power Headroom Report), Recommended bitrate MAC CE, etc., is also independent and is performed according to their own needs. From the perspective of the system and gNB, two UEs are maintained.

[0234] For mode 2, since all uplinks need to be transmitted on one UE, generally the primary UE, because the primary UE usually has better capabilities or link monitoring mechanisms, it is necessary to distinguish UE IDs during transmission. For L1 information, there are two ways to distinguish UE IDs:

[0235] First, different time-frequency resource locations are allocated to different UEs in terms of resource locations, thereby naturally distinguishing UEs;

[0236] Second, the UE ID is carried in the signaling content. If there are two UEs, 1 bit is used to distinguish between the primary and secondary UEs.

[0237] For MAC CE, since MAC CE is multiplexed transmission, it is impossible to distinguish UEs from the transmission time and frequency resources. Therefore, the only way is to add a field to distinguish UE ID in the MAC CE PDU format and expand the cascading of two or more UE reports to increase the reporting distinction and efficiency.

[0238] For the UE side, the second UE needs to pass its L2 / L1 reporting content to the first UE, and then the first UE reports. In addition, since the reporting process also maintains the timer of the control information, such as the BSR retransmission timer, the BSR cycle timer, etc., it is recommended that these timers are also maintained separately on a per-UE basis, that is, each UE maintains its own, or the first UE can maintain it uniformly, and each UE can interact with the first UE to trigger the status update of the timer, etc.

[0239] Embodiment 3: Resource scheduling.

[0240] Resource scheduling is divided into two categories: dynamic resource scheduling and semi-static resource scheduling.

[0241] Since dynamic resource scheduling is highly time-sensitive and generally requires a response within a few milliseconds, it is recommended that different UEs perform it independently. That is, the first UE's dynamic scheduling monitors the PDCCH scheduling information encrypted by its own C-RNTI, and receives or sends according to the resource location indicated by the scheduling information, so that the subsequent feedback location is also based on the existing one, and the same is true for the second UE.

[0242] Allocation and activation of semi-static resources. Semi-static resources are divided into two types. One is that the RRC signaling directly indicates the time-frequency resource location and period information, and the UE can use it directly without any activation. The other is that the RRC signaling only indicates the period information, and the time-frequency resource location information still needs to listen to PDCCH scheduling or activation.

[0243] There are two ways to distinguish the RRC signaling part in these two types of semi-static resource allocation:

[0244] One is to send RRC signaling to different UEs separately and allocate semi-static resources only to the UE;

[0245] The other is to send a unified RRC signaling to the first UE, and clearly specify in the signaling which UE the semi-static resource is for, or to allow the UE to negotiate on its own without specifying, and then each UE obtains its own semi-static resource configuration.

[0246] Generally speaking, each UE can only send and receive data at its own semi-static resource location. In particular, if a UE's semi-static resource has no data to send, it can quickly interact with the UEs to transfer the semi-static resources once or multiple times, and send the data from another UE that has data. The network side can distinguish UE data by carrying explicit UE ID or implicit LCID and other information.

[0247] It can be seen that in the embodiment of the present application, in the multi-UE operation, the UE performs the transmission operation independently or the master UE assists the slave UE in performing the transmission operation.

[0248] In the TA acquisition of the secondary UE, the secondary UE can use the contention random access process of the normal UE to obtain the TA or TA+C-RNTI. The secondary UE reports the association with the primary UE to the network;

[0249] The primary UE may obtain dedicated random access resources from the network and forward the resources to the secondary UE, so that the secondary UE can obtain the TA or TA+C-RNTI using a non-contention random access procedure.

[0250] Multiple UEs independently perform dynamic scheduling reception and subsequent transmission and feedback. Multiple UEs each obtain semi-static resources through the RRC process, and use and feedback.

[0251] The network sends the semi-static resources of multiple UEs to the master UE through the RRC process and explicitly indicates the resource allocation of each UE, which is either allocated by the master UE or negotiated by the UE and distributed to each UE.

[0252] Semi-static resources can be temporarily transferred between UEs;

[0253] The network can allocate independent PUCCH resources to each UE for physical layer reporting.

[0254] Each UE can independently perform the MAC CE reporting process.

[0255] The network may send the PUCCH resource allocations of all UEs to the master UE, which then assists in reporting for other UEs.

[0256] The master UE can assist in MAC CE reporting for other UEs and distinguish UEs in the MAC CE PDU format, cascade, etc.

[0257] Through the embodiments of the present application, the RAN side can configure aggregated bearers or individual bearers for multiple UEs, so that the UE can transmit with multiple devices under the control of the network side, thereby ensuring the UE's service experience and system efficiency.
