Detailed Description
The present application will be described in further detail with reference to the following drawings and examples.
In the related art, the designed access network is mainly oriented to a ground network and is not suitable for the integrated scene of the access network in the air, the sky and the ground.
On the other hand, in the related art, the user identifier for terminal scheduling mainly includes a cell radio network temporary identifier (C-RNTI) and a modulation and coding strategy cell radio network temporary identifier (MCS-C-RNTI); wherein, the C-RNTI is used for a common scene, and the MCS-C-RNTI is used for an ultra-reliable low-delay communication (URLLC) scene. In the sky-ground integrated Yangtze river, the scheduling of the terminal may encounter more scenes, for example, in the case of a longer propagation delay, the scheduling of the UE may correspond to different processing flows. Therefore, in order to further optimize the use of the access network in the air-space-ground integrated scenario, it may be considered to introduce different user identifiers to perform corresponding different air interface transmission method processing.
Based on this, in various embodiments of the present application, a new user identifier is introduced for a scene with a large transmission delay (transmission delay may also be referred to as propagation delay), and a network side and a terminal side can know a scene where a current network is located according to different user identifiers.
An embodiment of the present application provides a data transmission method, which is applied to a network device (specifically, a network device of an access network, such as a base station), and as shown in fig. 2, the method includes:
step 201: determining that the terminal is in a first network environment; the transmission delay is high in the first network environment;
step 202: carrying out data transmission with the terminal by utilizing the first user identification of the terminal; wherein the content of the first and second substances,
the first user identification is different from a second user identification of the terminal; the second user identification is used for scheduling and data transmission of the terminal when the terminal is in a second network environment; the second network environment represents that the terminal is in a ground network.
The terminal may also be referred to as User Equipment (UE) or a user.
In practical applications, the first user identity may be a Radio Network Temporary Identity (RNTI), and the first user identity is a new RNTI compared with the RNTI in the related art.
The first user identifier is used for identifying scheduling of the terminal in a specific scene after the terminal establishes connection, and specifically, identifying scheduling in a large-delay transmission scene. When the first user identifier is used, it is described that an air interface link (which may also be understood as current transmission) where the terminal is currently located is large transmission delay, and corresponding physical layer or higher layer processing flows are different. For example, for terminals using satellite communication and underwater communication, user identification other than a terrestrial network may be employed.
Here, in practical application, the network device may estimate a transmission delay (for example, estimate the transmission delay according to the time of arrival of uplink data), and may also obtain the transmission delay in a manner that the terminal reports the transmission delay, and when the transmission delay is longer than a preset time (which may be set as required), it is determined that the transmission delay is high, and the terminal is currently located in the first network.
The network device selects a subscriber identity suitable for the current use. And when the terminal is determined to be in the first network environment, namely corresponding to a large delay scene, notifying the terminal by using the control information scrambled by the first user identification during uplink and downlink scheduling of the terminal.
Based on this, in one embodiment, first control information is sent to the terminal; and scrambling the first control information by adopting the first user identification.
Here, in practical application, the first control information may be Downlink Control Information (DCI), that is, the first user identifier may be used for scrambling processing of a Physical Downlink Control Channel (PDCCH). Accordingly, the first subscriber identity may be used for a terminal for descrambling of the PDCCH.
Accordingly, the first subscriber identity may be used for scrambling of a Physical Downlink Shared Channel (PDSCH) when data transmission is performed. Accordingly, the first subscriber identity may be used for a terminal for descrambling of the PDSCH.
That is, the first subscriber identity may be used for scheduling and data transmission of the terminal in a downlink when the terminal is in a first network environment.
Of course, the first subscriber identity may also be used for scheduling and data transmission in uplink for the terminal when the terminal is in the first network environment.
Based on this, in an embodiment, the network device receives second control information (such as HARQ ACK/NACK, etc.) and/or data sent by the terminal, that is, the first user identifier may be used for descrambling of a Physical Uplink Shared Channel (PUSCH); accordingly, the first user identification is used for a terminal for scrambling processing of a PUSCH.
By introducing the first subscriber identity, under the same access network architecture, such as the network architecture shown in fig. 1, the network device may determine an appropriate air interface transmission mechanism according to the transmission delay, so as to be compatible with different air interface transmissions, thereby achieving characteristics of an air interface environment and achieving the purpose of adaptive delay.
In practical application, the first user identifier is also required to be configured for the terminal, so that the terminal can obtain the first user identifier, and subsequently, the first user identifier can be used to acquire a scene with high transmission delay, and correspondingly process received information and data.
Based on this, in an embodiment, the method may further include:
and configuring the first user identification to the terminal.
Here, in actual application, the first ue may be configured to the terminal through RRC signaling.
Specifically, the first ue may be configured to the terminal through RRC signaling in a process of using RRC signaling, such as in an RRC connection establishment process, or in an RRC connection establishment reconfiguration, or in an RRC link re-establishment process, and so on.
Illustratively, the first subscriber identity may be configured in this Information Element (IE, Information Element) of a physical cell group configuration (expressed in english as physical cell group configuration), as follows:
PhysicalCellGroupConfig information element
wherein X-RNTI represents the first user identification.
In actual application, the first subscriber identity may be configured to the terminal through the native MAC CE.
Illustratively, the network side marks the corresponding content and format of the MAC CE by sending a logical channel id (lc id) corresponding to the MAC CE indicating the first subscriber identity, as shown in table 1. And marking the corresponding MAC CE as the first user identifier through the specified LC ID value, and analyzing according to a format corresponding to the first user identifier.
TABLE 1
In practical application, the first subscriber identity in the MAC CE may adopt the format shown in fig. 3. In fig. 3, X-RNTI represents the first subscriber identity.
After the terminal acquires the first subscriber identity, the first subscriber identity is stored, and the first subscriber identity may be actively reported to the network device when needed, for example, the conditions of cell handover, cell reselection, beam recovery or synchronization loss, and the like.
Based on this, in an embodiment, the method may further include:
and receiving the first user identification reported by the terminal.
Here, in actual application, the first user identifier reported by the terminal may be received through an RRC signaling, for example, the terminal carries the first user identifier in an RRC connection establishment request. The first user identifier reported by the terminal can also be received through the MAC CE.
The first user identifier is a user identifier of the terminal in a special scenario, and a value of the first user identifier may be consistent with a value of the user identifier in the ground network, for example, a value range of the first user identifier includes 0001-FFF 2.
Correspondingly, an embodiment of the present application further provides a data transmission method, which is applied to a terminal, and includes:
data transmission is carried out on data needing to be transmitted in a first network environment by adopting a first user identifier of the terminal; wherein the content of the first and second substances,
the terminal is in a first network environment; the transmission delay is high in the first network environment; the first user identification is different from a second user identification of the terminal; the second user identification is used for scheduling and data transmission of the terminal when the terminal is in a second network environment; the second network environment represents that the terminal is in a ground network.
In an embodiment, the receiving network side receives first control information sent by the network side; scrambling the first control information by adopting the first user identification;
descrambling by using the first user identification to obtain the first control information.
Here, after the terminal descrambles the first control information successfully by using the first subscriber identity, it can be determined that the terminal is in the first network environment and needs to perform data transmission with the network side by using the first subscriber identity.
And the terminal receives uplink and downlink scheduling and data corresponding to the first user identifier and can process the uplink and downlink scheduling and data by adopting a corresponding physical layer processing mode under the condition of large transmission delay.
Specifically, at the time of data transmission, at the physical layer, the scrambling is performed by using the first subscriber identity. That is, the terminal needs to adopt an air interface transmission mode matched with the first network environment.
In an embodiment, the method may further comprise:
and receiving the first user identification configured by the network side.
