Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and more specifically to a data transmission method, apparatus, communication device, and computer storage medium. Background Technology

[0002] 5G and Artificial Intelligence (AI) are gradually integrating into people's lives, and in the upcoming 6G era, AI will inevitably become an indispensable part of network architecture. Currently, the integration of network architecture and AI is still in its early stages of research. This integration faces challenges related to data source sourcing. The data required for artificial intelligence involves multiple fields, and in wireless systems, data exists in silos. Considering security and other factors, data sharing also faces significant challenges. Federated learning offers a feasible solution to data privacy protection. Under the premise of satisfying data privacy and security, federated learning gains benefits by keeping data from each party locally and establishing a virtual shared model through multiple collaborative groups.

[0056] The application will be further described in detail below with reference to the drawings and specific embodiments.

[0057] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as a Global System of Mobile communication (GSM) system, a Long Term Evolution (LTE) system, or a 5G system, etc. The 5G system or 5G network can also be referred to as a New Radio (NR) system or NR network.

[0058] For example, the communication system to which the embodiments of the present application are applied can include a network device and a user equipment (UE). The network device can be a device that communicates with the user equipment (or referred to as a communication terminal, terminal, terminal device). The network device can provide communication coverage for a specific geographic area, and can communicate with the terminal device located in the coverage area. Optionally, the network device can be a base station in a GSM system or a CDMA system, or an evolved node B (eNB or eNodeB) in an LTE system, or a base station (gNB) in a 5G system or an NR system, etc.

[0059] Figure 2 A scenario diagram for applying federated learning to a network architecture is shown in FIG. 1. Figure 9 As shown in FIG. 1, wi (such as w1, w2, …, wu shown in the figure) is a local federated learning model (or local federated model) of the i-th terminal, g is a global federated learning model, the terminal performs model training based on local data at the local end to obtain a local federated learning model, and the trained local federated learning model is transmitted to the base station. The base station calculates the global federated model g according to the local federated learning models of the terminals, and sends the global federated model g to each terminal.

[0060] In this way, the transmission of the local data of the terminal to the base station can be reduced, and the amount of data transmission can be effectively reduced. However, since the base station needs to receive the local federated learning models sent by all terminals, and uniformly calculates the global federated model according to all local federated learning models, the consistency of the arrival time of the local federated learning model and the effectiveness of the transmission are required. Based on this, the following embodiments of the present application are proposed.

[0061] The embodiment of the present application provides a data transmission method applied to a network device. Figure 1 A flowchart of the data transmission method of the embodiment of the present application is shown in FIG. 2. Figure 1 As shown in FIG. 2, the method comprises the following steps. Figure 2

[0062] ​Step 101: The network device sends common resource configuration information to user equipment in a user group, the common resource corresponding to the common resource configuration information being a common resource corresponding to the user group; the common resource being used for the user equipment to transmit data.

[0063] In this embodiment, by centralized scheduling of the common resource of the user group by the network device, resources are uniformly allocated to users in the user group, unified scheduling of the users in the user group is completed, and the scheduling results of the users in the user group are sent using the same uplink authorization, which can effectively reduce the time interval of data arrival between users, reduce the control signaling overhead of data scheduling, and ensure the effectiveness and reliability of federated learning.

[0064] In some optional embodiments, the network device sends common resource configuration information to user equipment in a user group, including: the network device sends configuration information to one or more user equipment included in the user group, the configuration information including the common resource configuration information.

[0065] In this embodiment, the network device can carry the above-mentioned common resource configuration information by sending configuration information to user equipment in the user group, and the above-mentioned configuration information is mainly used for configuring users in the user group. For example, the network device sends configuration information to one or more user equipment to inform the one or more user equipment that they are a user group.

[0066] Optionally, the configuration information further includes at least one of the following information: a common user identifier, a number of users in the user group, a user identifier corresponding to the user equipment, and a number of HARQ processes corresponding to the common resource.

[0067] The common user identifier corresponds to the user group, and it can be understood that all user equipment in the user group correspond to the same common user identifier. The common user identifier is used for scrambling of uplink and downlink authorization of user equipment in the user group, scrambling of transmission of user data in the group, and the like. The user identifier of the user equipment may, for example, be an index of the user equipment, and the index can have a value range of 0 to the number of users in the user group-1. In this embodiment, users in the user group can be added or deleted at any time, that is, the network device can update users in the user group by sending configuration information.

[0068] For example, the common resource can be a set of resources configured by the network device for the user equipment in the user group, and the user equipment in the user group can select a suitable resource from the set of resources for transmission when data transmission or uplink grant transmission is required. In an embodiment, the common resource (i.e., the set of resources) is labeled in the time domain and the frequency domain, and the label of the corresponding resource is configured for each user in the user group. In another embodiment, the common resource (i.e., the set of resources) is equally divided according to the number of users in the user group, and can be allocated in sequence according to the user identifier in the user group.

[0069] For example, the set of resources can be periodic resources, and the configuration information can further include a period corresponding to the periodic resources. For another example, the resources configured by the network device can also be resource block group (RBG) resources, and the common resource included in the configuration information can be the index of the RBG allocated for each user.

[0070] For example, the code example of the above configuration information can be as follows:

[0071] UEGroupConfig ::= SEQUENCE {

[0072] GroupCommonCRNTI

[0073] NumberOfUE (corresponding to the number of users in the user group)

[0074] UEIndexinGroup (corresponding to the user identifier of the user equipment in the user group)

[0075] resourceAllocation (resource configuration, corresponding to the above common resource configuration information)

[0076] periodicity (period corresponding to the periodic resource)

[0077] rbg-Size (RBG size)

[0078] nrofHARQ-Processes (number of HARQ processes corresponding to the common resource)

[0079] Optionally, the network device sends the configuration information to one or more user equipment included in the user group, including: the network device sends the configuration information to one or more user equipment included in the user group through RRC signaling.

[0080] In some alternative embodiments, the network device sends the common resource configuration information to the user equipment in the user group, comprising: the network device sends a grant notification, wherein the grant notification comprises the common user identifier and the common resource configuration information; the common user identifier is used for one or more user equipments in the user group to receive the grant notification.

[0081] In the embodiment, the network device can carry the common resource configuration information by sending a grant notification to the user equipment in the user group. The embodiment is applicable to the scenario that the user group has been configured by the configuration information. In the case that the user group has been configured, the network device can send a grant notification, wherein the grant notification comprises the common user identifier and the common resource configuration information. Generally, all user equipments in the user group can receive the grant notification and obtain the common resource configuration information carried in the grant notification.

[0082] For example, the resource set can be a periodic resource, and the configuration information can further comprise a period corresponding to the periodic resource. For another example, the resource configured by the network device can also be an RBG resource, and the common resource comprised in the configuration information can be an index of the RBG allocated to each user.

[0083] Optionally, the grant notification further comprises at least one of the following information: time information of uplink and downlink data transmission, modulation information.

[0084] In some alternative embodiments of the present application, the common resource comprises one of the following: time-domain time-determined frequency-domain resource, time-domain time-determined frequency-domain resource, time-domain time-determined frequency-domain resource, time-domain time-determined frequency-domain resource.

[0085] Figure 1 A schematic diagram of the common resource in the data transmission method of the embodiment of the present application is shown in FIG. 1, wherein the common resource is a time-domain time-determined frequency-domain resource, i.e., the time domain is determined, and different users correspond to different frequency-domain resources. Figure 2 A schematic diagram of the common resource in the data transmission method of the embodiment of the present application is shown in FIG. 1, wherein the common resource is a time-domain time-determined frequency-domain resource, i.e., the time domain is determined, and different users correspond to different frequency-domain resources. Figures 3a to 3d A schematic diagram of the common resource in the data transmission method of the embodiment of the present application is shown in FIG. 1, wherein the common resource is a time-domain time-determined frequency-domain resource, i.e., the time domain is determined, and different users correspond to different frequency-domain resources. Figure 3a A schematic diagram of the common resource in the data transmission method of the embodiment of the present application is shown in FIG. 1, wherein the common resource is a time-domain time-determined frequency-domain resource, i.e., the time domain is determined, and different users correspond to different frequency-domain resources. Figure 3bAs shown, the frequency domain resource is a specific time length of a periodic resource, i.e., the common resource is a frequency domain periodic resource, and in each frequency domain period, different time domain resources correspond to different users.

[0086] In some optional embodiments, the authorization notification further includes MCS information. For example, the MCS information can be an MCS index value.

[0087] In some optional embodiments, the MCS information of one or more user equipment included in the user group corresponds to the user identification of the user equipment.

[0088] In this embodiment, the network device configures one MCS information for each user equipment in the user group, as shown in Table 1.

[0089] Table 1

[0090]

[0091] In some other optional embodiments, the MCS information of one or more user equipment included in the user group corresponds to the common user identification.

[0092] In this embodiment, the network device configures an MCS for the user group, which can be referred to as a common MCS. In the previous embodiment, the MCS configured for each user equipment can be referred to as a UE-specific MCS. If the common MCS of this embodiment is used, only the common MCS needs to be carried in Table 2, and no UE-specific MCS needs to be carried subsequently. If the UE-specific MCS is used, the corresponding MCS can be determined according to the identification (such as the index) of the UE. Alternatively, in some embodiments, for the user equipment in the user group, some users can correspond to the UE-specific MCS, and some users can correspond to the common MCS. If the identification of a UE is set to a specific MCS, the user equipment can correspond to the MCS corresponding to the UE index (i.e., the UE-specific MCS). If the identification of a UE is not set to a specific MCS, the common MCS in the group can be used.

[0093] Table 2

[0094]

[0095] This embodiment can ensure that the transmission time interval of uplink and downlink data is as small as possible, and can reduce the signaling redundancy of uplink and downlink authorization and the number of transmissions of the corresponding PDCCH.

[0096] In this embodiment, the configuration information may further include the number of HARQ processes corresponding to public resources. User equipment within the group uses a unified HARQ process number, and uplink and downlink data using the public user identifier correspond to the same HARQ process. The HARQ process corresponding to the public user identifier is maintained separately.

[0097] In some alternative embodiments of the present invention, such as Figure 3c As shown, based on step 101, the method may further include:

[0098] Step 102: The network device receives data from user equipment within the user group, the data being scrambled based on the public user identifier; the data transmitted by the user equipment within the user group corresponds to the same HARQ process.

[0099] Optionally, the method further includes: if the network device does not receive data from the first user device in the user group, resending the authorization notification to the first user device; the first user device is at least some of the user devices included in the user group.

[0100] In this embodiment, the network device generates a corresponding authorization notification based on whether the data of each user device in the user group has been transmitted correctly, and sends the authorization notification only to the user devices that need to retransmit.

[0101] Figure 3d This is a schematic diagram of the authorization notification retransmission in the data transmission method of this invention; as shown. Figure 4 As shown, the user group includes UE1, UE2, UE3, UE4, and UE5. The base station sends an authorization notification for this user group. If all five UEs receive the authorization notification, they send feedback information (i.e., uplink authorization) to the base station. This means the network device receives data from the user equipment within the user group. The feedback information is scrambled based on a common user identifier, and each user equipment within the user group transmits feedback information corresponding to the same HARQ process. If the base station does not receive feedback information from UE3 and UE4, it resends the authorization notification to UE3 and UE4. After receiving the authorization notification, UE3 and UE4 send feedback information (i.e., uplink authorization) to the base station. Further assuming the base station still does not receive feedback information from UE4, it resends the authorization notification to UE4. After receiving the authorization notification, UE4 sends feedback information (i.e., uplink authorization) to the base station.

[0102] In this way, by scheduling retransmissions by group users, the overhead of HARQ process numbers can be reduced, the consistency of retransmission time can be guaranteed, and the time interval can be reduced.

[0103] Based on the foregoing embodiments, this invention also provides a data transmission method applied in a user equipment. Figure 5As shown in Fig. 3, the method comprises the following steps. Figure 5

[0104] Step 201: A user equipment receives common resource configuration information from a network device, the user equipment being one of user equipments in a user group; the common resource corresponding to the common resource configuration information being a common resource corresponding to the user group;

[0105] Step 202: The user equipment transmits data based on the common resource configuration information.

[0106] In this embodiment, the network device centrally schedules resources in the common resources of the user group, uniformly allocates resources to users in the user group, completes unified scheduling of the users in the user group, and sends the scheduling results of the users in the user group using the same uplink authorization, which can effectively reduce the time interval of data arrival between users, reduce the control signaling overhead of data scheduling, and ensure the effectiveness and reliability of federated learning.

[0107] In some optional embodiments, the user equipment receives common resource configuration information from a network device, comprising: the user equipment receives configuration information from the network device, the configuration information comprising the common resource configuration information.

[0108] In this embodiment, the network device can carry the above-mentioned common resource configuration information by sending configuration information to the user equipments in the user group, and the above-mentioned configuration information is mainly used for configuring the users in the user group.

The common user identifier is used for scrambling of uplink and downlink authorizations of user equipments in the user group, scrambling of transmission of user data in the group, and the like. The user identifier of the user equipment may, for example, be an index of the user equipment, and the index may, for example, have a value range of 0 to the number of users in the user group-1. In this embodiment, users in the user group can be added or deleted at any time, that is, the network device can update the users in the user group by sending configuration information.

[0111] ​For example, the common resource can be a set of resources configured by the network device for the user equipment in the user group, and the user equipment in the user group can select a suitable resource from the set of resources for transmission when data transmission or uplink grant transmission is required. In an embodiment, the common resource (i.e., the set of resources) is labeled in the time domain and the frequency domain, and the label of the corresponding resource is configured for each user in the user group. In another embodiment, the common resource (i.e., the set of resources) is equally divided according to the number of users in the user group, and can be allocated in sequence according to the user identifier in the user group.

[0112] For example, the set of resources can be periodic resources, and the configuration information can further include a period corresponding to the periodic resources. For another example, the resources configured by the network device can also be resource block group (RBG) resources, and the common resource included in the configuration information can be the index of the RBG allocated for each user.

[0113] Optionally, the user equipment receives the configuration information from the network device, including that the user equipment receives the configuration information from the network device through RRC signaling.

[0114] In some optional embodiments, the user equipment receives the common resource configuration information from the network device, including that the user equipment receives a grant notification from the network device, and the grant notification includes the common user identifier and the common resource configuration information.

[0115] In this embodiment, the network device can carry the common resource configuration information by sending a grant notification to the user equipment in the user group. This embodiment is applicable to the scenario that the user group has been configured through the configuration information. In the case that the user group has been configured, the network device can send a grant notification once, and the grant notification includes the common user identifier and the common resource configuration information. Generally, all user equipment in the user group can receive the grant notification and obtain the common resource configuration information carried in the grant notification.

[0116] In some optional embodiments, the user equipment receives the grant notification from the network device, including that the user equipment receives the grant notification based on the pre-configured common user identifier.
