Description

Transmission processing method, terminal and network device TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of communication, and particularly relates to a transmission processing method, a terminal and a network device. BACKGROUND

[0002] In a communication system, after a terminal receives a downlink signal, the terminal can determine the position of a downlink signal subframe. In order to avoid uplink interference, a network device needs to ensure that signals sent by different terminals arrive at a fixed time, and therefore, the network side needs to configure a timing advance (TA) for the uplink transmission of a UE. After receiving the TA value, if the terminal needs to send an uplink signal, the terminal sends the uplink signal by further advancing the TA time value based on the position of the downlink subframe.

[0152] In some embodiments, the technical solutions of the present disclosure can be applied to an Open RAN architecture, at this time, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can become internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0153] In some embodiments, the access network device can be composed of a central unit (CU) and a distributed unit (DU), where the CU can also be referred to as a control unit. The CU-DU structure can split the protocol layers of the access network device, and some of the protocol layers are controlled by the CU, and the remaining or all of the protocol layers are distributed in the DU and controlled by the CU, but not limited thereto.

[0154] In some embodiments, the core network device can be one device including one or more network elements, or can be multiple devices or device groups including all or part of the one or more network elements. The network element can be virtual or physical. The core network includes at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next-generation core (NGC).

[0155] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed in the embodiments of the present disclosure. Those skilled in the art can know that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems.

[0156] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1 or part of the subject, but are not limited thereto. The subjects shown in FIG. 1 are examples, and the communication system can include all or part of the subjects in FIG. 1, or include other subjects other than FIG. 1. The number and form of each subject is arbitrary, each subject can be physical or virtual, the connection relationship between each subject is an example, each subject can not be connected or can be connected, and the connection can be in any way, can be direct connection or indirect connection, can be wired connection or wireless connection.

[0157] Embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based thereon, and the like. In addition, a plurality of systems can be combined (for example, combination of LTE or LTE-A and 5G, and the like).

[0158] In the embodiments of the present disclosure, the terminal needs to acquire the TA value only in the uplink out-of-sync state, and therefore, the terminal can trigger or the network device triggers the terminal to initiate a random access process, and the network sends the terminal a TA value in a random access response.

[0159] Since the location of the terminal is changing all the time, the validity of the TA value needs to be maintained. The network side TA value maintenance can set a time alignment timer (TAT) for the terminal TA value, start when the TA is issued to the terminal, and issue a new TA value to the terminal before the timer expires. The terminal TA value maintenance starts or restarts according to the timer set by the network side when receiving the TA value, and considers the TA value invalid after the timer expires. The terminal is in an out-of-sync state.

[0160] In some embodiments, one cell of the terminal can be configured with one primary timing advance group (PTAG) and up to three secondary timing advance groups (STAGs).

[0161] The special cell (or cell group) (SpCell) can only belong to the PTAG. The SpCell can include the primary cell (or cell group) (PCell) and the primary secondary cell (or cell group) (PSCell).

[0162] The secondary cell (or cell group) (SCell) can belong to the PTAG or the STAG.

[0163] In the 5G system, a dual connectivity (DC) architecture is adopted, including two cell groups: a master cell group (MCG) and a secondary cell group (SCG).

[0164] The MCG corresponds to the network side master node (MN), and the SCG corresponds to the network side secondary node (SN).

[0165] The MCG can include one PCell and one or more SCells, and the SCG can include one PSCell and one or more SCells.

[0166] FIG. 2 is another exemplary schematic diagram of an architecture of a communication system according to embodiments of the present disclosure; as shown in FIG. 2, since the terminal can be configured to send uplink signals to multiple different locations of transmission and reception points (such as TRP_1 and TRP_2) of the same cell, and the TA values referenced by the multiple different locations of transmission and reception points for sending uplink signals are not the same, different timing advance groups (TAGs) (such as corresponding to TA_1 and TA_2) can be configured for the multiple different transmission and reception points of the same cell respectively, and the same TAG can also correspond to multiple cells (such as Cell_1 and Cell_2), and the same TAG corresponding to multiple cells can be understood as that the TAG is configured to the multiple cells.

[0167] When the TAT timer corresponding to the TAG times out, the terminal stops the uplink transmission of all cells corresponding to the TAG. When the terminal is configured to send uplink signals to multiple different locations of transmission nodes of the same cell, since multiple different transmission and reception points of the same cell can be configured with different TAGs, and the same TAG can also correspond to multiple cells. At this time, how to manage the TAG of the terminal and the corresponding TAT so as to reduce the impact on uplink transmission is a problem to be solved, for example, interference or sending terminals caused by TAT timeout, i.e. TA unavailable.

[0168] FIG. 3 is an interaction schematic diagram of a transmission processing method according to embodiments of the present disclosure. As shown in FIG. 3, the embodiments of the present disclosure relate to a transmission processing method, and the method comprises:

The PCell is configured with 2 TAGs (TAG_1 and TAG_2), the SCell_1 is configured with 2 TAGs (TAG_2 and TAG_3), and the SCell_2 is configured with 2 TAGs (TAG_3 and TAG_4), each of which has a respective TAT.

[0176] In some embodiments, the terminal 101 can receive first information.

[0177] In some embodiments, the number of TAGs configured by the network device for the first cell can be 1 or multiple. No limitation is made in this regard.

[0178] In some embodiments, the type of the first cell can include at least one of a secondary cell SCell and a special cell SpCell, wherein the special cell SpCell includes a primary cell PCell or a primary secondary cell PSCell.

[0179] In some embodiments, under the MCG, there can be many cells, one of which is used to initiate initial access, which is called PCell. As the name implies, the PCell is the most "primary" cell in the MCG.

[0180] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and the terms "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "parameter", etc. can be replaced with each other.

[0181] In some embodiments, "acquire", "obtain", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be replaced with each other, which can be interpreted as receiving from other subjects, obtaining from protocols, obtaining from higher layers, processing to obtain, autonomous implementation, etc.

[0185] The second information is used to indicate whether the TAG configured for the first cell is expired and / or running.

[0186] In some embodiments, whether the TAG is expired can be understood as whether the TAT corresponding to the TAG is expired.

[0187] In some embodiments, whether the TAG is running can be understood as whether the TAT corresponding to the TAG is running.

[0188] In some embodiments, whether the TAG is expired can be determined according to whether the running time of the TAT corresponding to the TAG reaches a configured threshold value. If the running time of the TAT corresponding to the TAG reaches the configured threshold value, it is determined that the TAG is expired. If the TAT corresponding to the TAG starts running but the running time does not reach the configured threshold value, it is determined that the TAG is not expired.

[0208] In some embodiments, the terms of "frame", "radio frame", "subframe", "slot", "sub-slot", "mini-slot", "symbol", "symbol", "transmission time interval (TTI)", and the like can be replaced with each other.

[0209] In some embodiments, the timing difference between the TAGs of different cells being greater than or equal to the timing threshold can indicate that the TAGs have uplink transmission errors.

[0210] In some embodiments, the first condition can be that the type of the first cell is SpCell, and the number of TAGs is 1, and the TAG is timed out. The first condition can also be that the type of the first cell is SpCell, and the number of TAGs is multiple, and each TAG is timed out.

Optionally, the expired TAG is a PTAG.

Therefore, if each TAG corresponding to the first cell corresponds to the indication information, it means that the multiple TAGs corresponding to the first cell all have uplink transmission errors.

[0219] In some embodiments, the indication information can be determined according to the relationship between the timing difference between the TAG and other TAGs and the timing threshold. Optionally, in the case that the timing difference between the TAG and other TAGs is greater than or equal to the timing threshold, it is determined that the TAG has corresponding indication information, and the indication information can be used to indicate that the timing difference between the corresponding TAG and other TAGs is greater than or equal to the timing threshold.

[0237] In some embodiments, the number of TAGs corresponding to the first cell is multiple, at least one TAG is expired, and at least one TAG is running. That is, the multiple TAGs corresponding to the first cell include an expired TAG and a running TAG. For example, one SCell corresponds to two TAGs, STAG-1 and STAG-2, the TAT corresponding to STAG-1 is expired, and the TAT corresponding to STAG-2 is running. Alternatively, the TAG whose TAT is expired can be a STAG or other TAG that is not a PTAG. Alternatively, the TAG to which the non-running TAT belongs is a STAG.

[0238] In some embodiments, the number of TAGs corresponding to the first cell is multiple, at least one TAG is expired, and at least one TAG is not running.
