It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in sequences other than those illustrated or described herein, and "first", "second" distinguishes Usually it is a class, and the number of objects is not limited. For example, the first object may be one or multiple. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

It is worth noting that the technologies described in the embodiments of this application are not limited to Long Term Evolution (LTE)/LTE-Advanced (LTE-Advanced, LTE-A) systems, and can also be used in other wireless communication systems, such as code Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (Orthogonal Frequency Division Multiple Access, OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used not only for the above-mentioned systems and radio technologies, but also for other systems and radio technologies. However, the following description describes a New Radio (NR) system for example purposes, and uses NR terminology in most of the following description, these techniques are also applicable to applications other than NR system applications, such as 6th generation (6 ^th Generation, 6G) communication system.

FIG. 1 shows a block diagram of a wireless communication system to which the embodiments of the present application can be applied. The wireless communication system includes a terminal 11 and a network side device 12. The terminal 11 may also be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 may be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital computer Assistant (Personal Digital Assistant, PDA), PDA, Netbook, Ultra-mobile Personal Computer (UMPC), Mobile Internet Device (MID), Wearable Device (Wearable Device) or vehicle-mounted device (VUE), pedestrian terminal (PUE) and other terminal-side devices, wearable devices include: bracelets, headphones, glasses, etc. It should be noted that, the embodiment of the present application does not limit the specific type of the terminal 11 . The network side device 12 may be a base station or a core network, wherein the base station may be referred to as a Node B, an evolved Node B, an access point, a Base Transceiver Station (BTS), a radio base station, a radio transceiver, a basic service Set (Basic Service Set, BSS), Extended Service Set (Extended Service Set, ESS), Node B, Evolved Node B (eNB), Home Node B, Home Evolved Node B, WLAN Access Point, WiFi Node, Send Transmitting Receiving Point (TRP) or some other suitable term in the field, as long as the same technical effect is achieved, the base station is not limited to specific technical terms. The base station in the NR system is taken as an example, but the specific type of the base station is not limited.

In order to enable those skilled in the art to better understand the information reporting method in the embodiments of the present application, the following description is first provided.

1. Dual Connectivity (DC).

Dual connectivity means that the UE is provided with resources of two network nodes (access network elements), one of which is called a master node (Master node, MN), and the other is called a secondary node (Secondary node, SN). At each network node, a carrier aggregation technology (Carrier Aggregation, CA) is used, that is, a series of serving cells controlled by the node are configured for the UE, also called a cell group (cell group). The MN controls the master cell group (Master Cell Group, MCG), and the SN controls the secondary cell group (Secondary Cell Group, SCG). Each cell group includes a special cell (Special Cell, SpCell) and a series of secondary cells (Secondary Cell, Scell). In the MCG, the special cell is called a primary cell (Primary Cell, PCell), and in the SCG, the special cell is called a primary secondary cell (Primary Secondary Cell, PSCell). In one cell group, the SpCell uses the primary carrier, while other secondary cells use the secondary carrier, and the resource scheduling in one cell group is performed by the SpCell.

2. SCG deactivated state.

In the related art, the SCG suspended (suspended) state is introduced. When the UE has low data transmission or no data transmission for a long time, the network can temporarily suspend the SCG instead of directly deleting the SCG and waiting for larger data. Add it back when it appears. By temporarily suspending the SCG, the terminal can work in a more power-saving manner for a longer period of time, and at the same time, the SCG can be resumed quickly when a large amount of data is required. In the related art, the term SCG deactivation is used. Currently, the behavior of the UE and the network control method in the SCG deactivation state are being discussed. It can be determined that the UE does not monitor the PDCCH on the SCG during the deactivation of the SCG. For other UE behaviors during SCG, some behaviors will be limited to save UE power consumption, and some behaviors may continue to be executed to speed up the activation or recovery of SCG, so that data transmission can be started quickly when the data volume recovers.

3. CSI Reference Signal (CSI-RS) measurement and reporting.

CSI measurement includes periodic CSI measurement, semi-persistent CSI measurement and aperiodic CSI measurement. The CSI measurement is based on the CSI-RS or synchronization signal/physical broadcast channel signal block (Synchronization Signal and PBCH block, SSB) reference signal sent by the network side.

CSI reporting can be periodic reporting, semi-continuous reporting or aperiodic reporting, specifically:

Periodic CSI report (P-CSI): It is only transmitted on the Physical Uplink Control Channel (PUCCH), and the UE performs CSI measurement and reporting according to the Radio Resource Control (Radio Resource Control, RRC) configuration.

Semi-persistent CSI report (SP-CSI): transmitted on PUCCH or Physical Uplink Shared Channel (PUSCH). If SP-CSI is on PUCCH, the UE needs to activate SP-CSI measurement by MAC CE after receiving the reference signal and reporting configuration configured by RRC. The reporting of measurement results also requires the MAC CE to activate SP-CSI reporting. If SP-CSI is on PUSCH, the difference compared to SP-CSI on PUCCH is that it relies on downlink control information (Downlink Control Information, DCI) scheduling to report CSI.

Aperiodic CSI reporting (AP-CSI): transmitted only on PUSCH, and DCI triggers CSI measurement and reporting.

For example, when the LCID field is the first value, the corresponding MAC CE is the first MAC CE, and supports reporting of CSI measurement results of at most 8 serving cells. Then, the bit field of the serving cell sequence may be one byte, that is, 8 bits, and each bit is used to indicate whether the measurement result of the corresponding serving cell occurs. If there are more than 8 serving cells, a 4-byte serving cell sequence bit field may be used. Each bit in the serving cell sequence bit field is represented by Ci, where i represents the index number or number of the serving cell, and the value of Ci is used to identify whether the MAC CE contains the CSI measurement result of serving cell i. For example, when the value of Ci is a first value (for example, 1), it means that the MAC CE contains the CSI measurement result of the serving cell with index i, and when the value of this field is a second value (for example, 0), it means that The MAC CE does not include the CSI measurement result of the serving cell with index i.

Optionally, in this embodiment of the present application, when the MAC protocol data unit includes the CSI measurement results of at least two serving cells, the CSI measurement amount field of each serving cell occupies a certain number of bits, and the at least two serving cells occupy a certain number of bits. The order of arrangement of the CSI measurement quantity fields of the serving cell is determined according to the bits of the serving cell sequence or is determined according to the identifier or index of the serving cell.

For example, for the first MAC CE, when the MAC CE reports the CSI measurement results of at most 8 serving cells, if the serving cell sequence bit fields are C ₈ =0, C ₇ =1, C ₆ =0, C ₅ respectively =0, C ₄ =1, C ₃ =1, C ₂ =0, C ₁ =0, C ₀ =1, then the CSI measurement field will contain the CSI measurement results of the serving cells with index numbers 1, 4, and 7 , and the order of appearance or reading of the CSI measurement results of the serving cells with index numbers 1, 4, and 7 may be:

1) arrange from small to large according to the serving cell index number: the measurement result of serving cell 1, the measurement result of serving cell 4, the measurement result of serving cell 7;

2) Arrange from large to small according to the serving cell index number: the measurement result of serving cell 7, the measurement result of serving cell 4, and the measurement result of serving cell 1;

3) Determine according to the serving cell sequence bits: the measurement result of serving cell 7, the measurement result of serving cell 4, and the measurement result of serving cell 1;

Optionally, the type field includes at least one type identifier, and each type identifier corresponds to a combination type of CSI measurement quantities;

Alternatively, the type field includes a bitmap, and each bit in the bitmap is used to indicate whether a CSI measurement quantity is reported.

The measurement quantity combination type may be agreed by the protocol, configured by the network, or reported by the terminal.

The type field can be per cell, that is, there is a type field for each serving cell to indicate the reported measurement combination type. The type field may also be per UE, that is, the indicated measurement quantity combination type is applicable to all serving cells of the UE. The type field may also be per cell group. For example, the first type field indicates the measurement combination type of all serving cells in the primary cell group, and the second type field indicates the measurement combination type of all serving cells in the secondary cell group. The type field may also be for a cell with only one characteristic. For example, the type field specifies the type of measurement combination only used to indicate the reported primary and secondary cells.

In an embodiment of the present application, the type field occupies 1 to multiple bytes, and the measurement combination type is identified by the type identifier, for example, the

identifiers

1, 2, 3, 4, 5, 6, 7, and 8 are used to respectively identify The following measurement quantity combination types: CRI-RI-PMI-CQI, CRI-RI-I1, CRI-RI-I1-CQI, CRI-RSRP, CRI-SINR, SSB-Index-RSRP, SSB-Index-SINR, CRI- RI-LI-PMI-CQI, using 4 bits in total. When the type field of the MAC CE indicates 0001, it indicates that the CSI measurement amount field reported by the terminal may carry CRI, RI, PMI, and CQI measurement results. When the type field indicates 0011, it indicates that the CSI measurement amount field reported by the terminal may carry CRI, RI, I1, and CQI measurement results. Among them, I1 represents the feedback information of the wideband PMI or the wideband information field (X1) of the PMI.

In an embodiment of the present application, whether the CSI measurement amount is reported is indicated by a bitmap. The bitmap can be specifically the CSI measurement sequence bits. For example, a bitmap of 1100000 indicates that only RI and CQI are reported in RI, CQI, PMI, CRI, SSBRI, LI, and L1-RSRP/L1-SINR. It can also be for each cell, or common to all cells, or only for PCell or only for SCell, or only for one cell group.

The MAC CE of the embodiments of the present application is specifically described below with reference to specific examples.

Example 1: The first MAC CE carries the CSI measurement results of multiple serving cells of the secondary cell group.

For example, the MAC control unit includes a MAC subheader and a MAC protocol data unit, and the MAC subheader includes an LCID field.

As shown in Table 1-1, Codepoint/Index is the first value of 35, which is used to indicate that the MAC control unit is the first MAC control unit (multiple CSI reports), and the MAC protocol data unit can carry secondary cells CSI measurement results of M serving cells in the group (serving cell sequence bit field occupies 1 byte), for example, M is 8.

Codepoint/Index is the second value 36, which is used to indicate that the MAC control unit is the first MAC control unit (multiple CSI reports), and the MAC protocol data unit can carry the CSI of the N serving cells of the secondary cell group The measurement result (the serving cell sequence bit field occupies S bytes), for example, S is 4 and N is greater than 8.

For example, as shown in Table 1-2, the MAC control unit includes a MAC subheader and a MAC protocol data unit, the MAC subheader includes an eLCID field, and the eLCID field includes a first parameter Codepoint and a second parameter Index . When the value of Codepoint is 0 and the value of Index is 64, it indicates that the MAC control unit is the first MAC control unit (multiple CSI reports), and the MAC protocol data unit can carry the M data of the secondary cell group. CSI measurement results of each serving cell (serving cell sequence bit field occupies 1 byte);

When the value of Codepoint is 1 and the value of Index is 65, it indicates that the MAC control unit is the first MAC control unit (multiple CSI reports), and the MAC protocol data unit can carry N of the secondary cell group. CSI measurement results of each serving cell (serving cell sequence bit field occupies S bytes).

Assuming that there are no more than 8 serving cells at most, and according to the agreement or network configuration, as shown in Figure 3, only RI and CQI are reported in the CSI measurement result of each serving cell, and RI and CQI occupy 1 and 4 bits respectively. The information carried by the actual MAC CE is shown in Figure 4, and the CSI measurement results of the serving cells with the serving cell index numbers of 7, 4 and 1 will appear. Wherein, byte 1 represents the serving cell sequence bit field, byte 2 represents the RI and CQI of the secondary cell 1, byte 3 represents the RI and CQI of the secondary cell 4, and byte 4 represents the RI and CQI of the secondary cell 7.

It is assumed that the protocol stipulates or the network configures that the UE only reports the measurement result of the SpCell. The network can also configure the terminal to report the CSI measurement result of a certain serving cell, for example, cell 2, then the UE only reports the CSI measurement result of serving cell 2 in the second MAC CE. Regarding which measurement quantities are carried in the measurement result of the serving cell, the indication methods in multiple CSI reports may be used.

If it is agreed in the protocol to report RI, CQI, PMI and L1, the CSI measurement quantity field carrying the serving cell in the second MAC CE includes RI, CQI, PMI and L1, as shown in FIG. 6 .

If the protocol does not stipulate that the UE reports the CSI measurement type of the serving cell, the UE can indicate that the measurement combination type is 1 in the type field, which means that the UE reports the CRI, RI, CQI, and PMI of the SpCell, as shown in FIG. 7 . Figure 8 shows whether the type field indicates whether various CSI measurement quantities are reported in the form of a bitmap.

Example 3: In the process of performing random access on the SCG, the SCG CSI measurement result is reported.

Step 1: The SCG is in the deactivated state, and the UE receives the SCG activation command;

Step 2: The UE initiates random access to the SCG or PSCell, and carries the MAC CE or the RRC message in the random access process (for example, in msg3);

Example 4: After activating the SCG or completing the random access, the SCG CSI measurement result is reported.

Step 1: The UE receives the SCG activation command;

Step 2: UE initiates random access in SCG or PSCell;

Step 3: On completion of random access or when the SCG is activated:

a) If there are UL resources for sending the MAC CE or the RRC message, the UE sends the MAC CE or the RRC message;

b) If the UL resource of the MAC CE or the RRC message is not sent, the UE sends a first request, and the first request is used to request the network side to allocate the UL resource for sending the MAC CE or the RRC message , such as sending a Scheduling Request (SR).

c) After receiving the reporting command sent by the network side, the UE sends the MAC CE or the RRC message, and the reporting command instructs the UE to report the MAC CE or the RRC message.

Example 5: Send the SCG CSI measurement result through the primary base station.

Step 1: the SCG is in a deactivated state, and the UE receives a reporting command from the primary base station, and the reporting command may be generated by the primary base station or generated by the secondary base station and forwarded by the primary base station;

Step 2: The UE sends the MAC CE or the RRC message to the primary base station.

Step 3: If the report command is generated by the secondary base station, once the primary base station receives the MAC CE or the RRC message, it can be forwarded to the secondary base station.
