The network device may provide one or more candidate configurations to the terminal device, wherein one candidate configuration may include one or more "cells or cell groups". The network device can subsequently control the terminal device to make changes in multiple "candidate configurations" through L1 or L2 signaling to implement serving cell changes. For example, L1 signaling is sent through Downlink Control Information (DCI), or L2 signaling is sent through Medium Access Control (MAC) control element (Control Element, CE) to change the working cell from "cell -1" was changed to "Community-2". This control signaling may be called "cell change control signaling". This process can also be called the LTM (L1/L2-triggeredMobility) process.

In addition, the terminal device can also perform cell changes based on the network's "preconfigured conditions" and the "candidate configuration" corresponding to the conditions. Among them, one candidate configuration may include one or more "cells or cell groups". When the terminal device meets the "preconfigured conditions", the terminal device can change the serving cell or cell group to the cell or cell group included in the "candidate configuration". This process can be summarized as a "conditionally triggered mobility process", which specifically includes: conditional handover (CHO); conditional primary and secondary cell or cell group addition (Conditional PSCell Addition) , CPA); conditional primary and secondary cell or cell group change (Conditional PSCellChange, CPC), etc.

In the Long Term Evolution (LTE) or 5G New Radio (NR) system, the transmission of uplink and downlink data is implemented through HARQ. As shown in Figure 1, the terminal device can have multiple media access control (Medium Access Control, MAC) entities, such as the master cell group (Master Cell Group, MCG) MAC and the secondary cell group (Secondary Cell Group, SCG) MAC. Each MAC entity has its own independent HARQ entity. Each HARQ entity is used to control the data transmission and reception of a cell or frequency point, such as CC1 in Figure 1, that is, the transmission and retransmission of data of a communication content (CommunicationsContent, CC) are all implemented through the same HARQ entity. .

Each HARQ entity has multiple HARQ processes, and different data can be sent and received through different HARQ processes. Among them, the number of HARQ processes on each CC is determined by the HARQ Round Trip Time (RTT), that is, the time from data sending to receiving feedback for the data. If the return time is 8 milliseconds and each data transmission time is 1 millisecond, in order to be able to send data at each time point, the number of HARQ processes is 8. Among them, the data interface between the MAC entity and the upper-layer entity is a logical channel (Logcical Channel, such as LCH1 in Figure 1). The data of multiple logical channels can be used as the same MAC protocol data unit (Multiplexing) through the multiplexing function. ProtocolData Unit (PDU) is sent in the HARQ process. In the 5G system, the network device can configure the number of HARQ processes used in a specific serving cell of the terminal device, such as 2 HARQ processes, or 4 HARQ processes, or 10 HARQ processes, or 12 HARQ processes, or 16 HARQ process, etc.

When the terminal device moves in different areas, the serving cell (or cell for short) is likely to switch. At this time, the cached data of the HARQ process of the terminal device will be cleared, which will cause the cached data of the HARQ process of the terminal device to be lost. Retransmissions are performed, resulting in more packet loss and reducing the reliability of data transmission.

To this end, this embodiment proposes a communication processing method and device. Through network configuration or protocol agreement, the terminal device can retain the data in the HARQ process of the terminal device during the mobility process, thereby reducing the mobility of the terminal device. packet loss during the process and increases the reliability of data transmission.

For example, if the source cell SCell-1 of the terminal device is changed to the target cell PCell, the terminal device associates the HARQ process of the source cell SCell-1 with the HARQ process of the target cell PCell.

In some examples, association may mean that two HARQ processes have the same status, where the status of the HARQ process may refer to cached data and/or corresponding NID values in the HARQ process.

In some examples, association may mean that two HARQ processes have an equal relationship. For example, the HARQ process corresponding to the candidate cell configuration information can be considered to be the HARQ process corresponding to the target cell, and the HARQ process for the target cell can be considered to be the HARQ process corresponding to the target cell. The HARQ process of the source cell is the same.

In some examples, association may mean that the HARQ process of the target cell inherits the work processing content of the HARQ process of the source cell.

For example, in related technologies, when the source cell is switched to the target cell, the cached data in the HARQ process A of the source cell will be cleared. However, by applying the method of this embodiment, the HARQ process B of the target cell can be connected to the source cell. HARQ process A is associated. During the process of switching the source cell to the target cell, when the cell configuration information of the terminal device is determined to be changed to the candidate cell configuration information, the HARQ process B is processed, such as retaining the cached information in the HARQ process B. data, thereby allowing the data cached in the HARQ process B to be retransmitted.

The method of this embodiment is also applicable to dual connectivity architecture (Dual Connectivity, DC) scenarios, which may include two cells or two cell groups. These two cell groups are a master cell group (Master Cell Group, MCG) and a secondary cell. Group (Secondary Cell Group, SCG). Among them, MCG corresponds to the master node (MN) on the network side. MCG includes one primary cell (Primary Cell, PCell) and one or more secondary cells (Secondary Cell, SCell); SCG corresponds to the secondary cell on the network side. Node (Secondary Node, SN), SCG includes 1 primary secondary cell (Primary Secondary Cell, PSCell), and 1 or more SCell. Here PCell and PSCell can be collectively referred to as Special Cell (SpCell).

For example, if the PCell of the terminal device is changed and/or the PSCell is changed, during the cell change process, the cell configuration information of the serving cell where the terminal device is located will be changed to the candidate cell configuration information. When the cell configuration information of the terminal device is determined to be changed to the candidate cell configuration When receiving information, the HARQ process corresponding to the candidate cell configuration information is processed.

In some embodiments, the terminal device processes the first HARQ process, which may include at least one of the following processing behaviors:

Processing behavior A: The terminal device retains the cached data in the first HARQ process;

Processing behavior B: The terminal device retains the new data indicator (New DataIndicator, NDI) value corresponding to the first HARQ process;

Processing behavior C: The terminal device sets the NDI value corresponding to the first HARQ process to a first value. The first value may be a preset value, such as "0" or "1";

Processing behavior D: The terminal device determines the next transmission data of the second HARQ process corresponding to the first MAC entity as newly transmitted data, wherein the first MAC entity is the MAC entity corresponding to the first HARQ process, and the second HARQ The process is a HARQ process other than the first HARQ process among the HARQ processes corresponding to the first MAC entity.

In this embodiment, for two consecutive data transmissions, the previous transmission data can be considered as the data of the last transmission, and the latter transmission data can be considered as the data of the next transmission. In order to facilitate understanding, "data transmitted last time" and "data transmitted next" are uniformly used for explanation below.

The NDI indication is used to control the newly transmitted data (that is, the data transmitted for the first time) and the retransmitted data (that is, the data that is transmitted again) of the HARQ process. When the NDI value (for example, NDI=0) of the "last transmitted data" of the same HARQ process is the same as the NDI value (for example, NDI=0) of the "next transmitted data", then the "next transmission The "data" is the retransmitted data of the "last transmitted data", and the terminal device combines and decodes the "next transmitted data" and "last transmitted data". When the NDI value of the "last transmitted data" (for example, NDI=0) of the same HARQ process is different from the NDI value of the "next transmitted data" (for example, NDI=1), then the "next transmitted data" "data" is newly transmitted data. Since the HARQ process can only cache data once, the terminal device will discard the "last transmitted data" and only decode the "next transmitted data".

For example, when the cell configuration information of the terminal device is determined to be changed to the candidate cell configuration information, the HARQ process corresponding to the candidate cell configuration information is determined to be the HARQ process M, and the terminal device retains the cached data in the HARQ process M and retains the HARQ process. The NDI value corresponding to process M, so that when the NDI value of the "next transmitted data" of the HARQ process M is the same as the NDI value of the "last transmitted data", the terminal device can combine the "next transmitted data" and "Last transmitted data" is merged and decoded. Furthermore, this embodiment can also limit that in addition to HARQ process M, the "next transmission data" of other HARQ processes corresponding to the MAC entity (MAC entity corresponding to HARQ process M) are all newly transmitted data, that is, only HARQ process M The corresponding cached data and the corresponding NDI value are retained, which is used to realize that the cached data in the HARQ process M can be retransmitted, thereby reducing the occurrence of data packet loss and improving the reliability of data transmission.

For another example, when the cell configuration information of the terminal device is determined to be changed to the candidate cell configuration information, it is determined that the HARQ process corresponding to the candidate cell configuration information is HARQ process N, and the terminal device retains the cached data in the HARQ process N, and can according to The NDI value of the "last transmitted data" of the HARQ process N is set to the NDI value corresponding to the HARQ process N. For example, the NDI value of the "last transmitted data" of the HARQ process N is 1, then the NDI value corresponding to the HARQ process N is set. The NDI value is 1. In this way, when the NDI value of the "next transmitted data" of the HARQ process M is 1, it can be determined to be the same as the NDI value of the "last transmitted data", and the terminal device can combine the "next transmitted data" and the "last transmitted data". "Data transmitted once" are merged and decoded. Furthermore, this embodiment can also limit that in addition to HARQ process N, the "next transmission data" of other HARQ processes corresponding to the MAC entity (MAC entity corresponding to HARQ process N) are all newly transmitted data, that is, only HARQ process N The corresponding cached data is retained and the NDI value is set accordingly, which is used to realize that the cached data in the HARQ process N can be retransmitted, thereby reducing the occurrence of data packet loss and improving the reliability of data transmission.

In some embodiments, which of the above-mentioned processing behaviors (processing behaviors A, B, C, and D) is specifically used can be determined according to the network configuration or protocol agreement. That is, correspondingly, the terminal device can be used according to the protocol agreement or agreement.

In some examples, the cell type in the indication information includes at least one of the following:
