The terms "system" and "network" in embodiments of the application are often used interchangeably, and the techniques described may be used for both the above-mentioned systems and radio technologies, as well as other systems and radio technologies. However, the following description describes a New Radio (NR) system for exemplary purposes, and NR terminology is used in much of the following description, these techniques may also be applied to applications other than NR system applications, such as a 6 th Generation (6G) communication system.
Fig. 1 shows a block diagram of a wireless communication system to which an embodiment of the present application is applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be referred to as a terminal device or a User Equipment (UE), and the terminal 11 may be a terminal-side device such as a Mobile phone, a tablet Computer (Tablet Personal Computer), a Laptop (Laptop Computer) or a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA), a palm Computer, a netbook, an ultra-Mobile Personal Computer (ultra-Mobile Personal Computer, UMPC), a Mobile internet device (Mobile INTERNET DEVICE, MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), and the wearable device includes: a bracelet, earphone, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application. The network side device 12 may be a base station or a core network, where the base station may be called a node B, an evolved node B, an access Point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a Basic service set (Basic SERVICE SET, BSS), an Extended service set (Extended SERVICE SET, ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access Point, a WiFi node, a transmission and reception Point (TRANSMITTING RECEIVING Point, TRP), or some other suitable terminology in the field, and the base station is not limited to a specific technical vocabulary so long as the same technical effect is achieved, and it should be noted that, in the embodiment of the present application, only 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 according to the embodiments of the present application, the following description is provided.
1. Dual connection (Dual Connectivity, DC).
A dual connection, i.e. providing the UE with resources of two network nodes (access network elements), one of which is called Master Node (MN) and the other is called Secondary Node (SN). At each network node, a carrier aggregation technique (Carrier Aggregation, CA) is used, i.e. a series of serving cells, also called cell groups (cell groups), controlled by the node are configured for the UE. MN controls the primary cell Group (MASTER CELL Group, MCG) and SN controls the secondary cell Group (Secondary Cell Group, SCG). Each Cell group contains one special Cell (SPECIAL CELL, SPCELL) and a series of Secondary cells (scells). The special cell is called a primary cell (PRIMARY CELL, PCELL) in the MCG, and the special cell is called a primary secondary cell (Primary Secondary Cell, PSCell) in the SCG. SpCell uses the primary carrier in one cell group, while other secondary cells use the secondary carrier, and resource scheduling within one cell group is performed by SpCell.
2. SCG deactivated state.
In the related art, an SCG suspended (suspended) state is introduced, and when the UE is low or no data transmission for a long period of time, the network may suspend the SCG temporarily, instead of deleting the SCG directly and then adding back again when larger data occurs. The SCG is temporarily suspended, so that the terminal can work in a more power-saving mode for a longer period of time, and the SCG can be recovered faster when a large amount of data is required. In the related art, the statement of SCG deactivation (SCG deactivation) is used. Currently, the UE behavior and network control manner when SCG is deactivated are being discussed, and it may be determined that during SCG deactivation, the UE does not monitor PDCCH on SCG. For other UE behaviors during SCG, some behaviors may be limited to save UE power consumption, and another part of behaviors may continue to be performed to speed up activation or restoration of SCG so that data transmission may be started quickly when data volume is restored.
3. CSI reference signal (CSI REFERENCE SIGNAL, CSI-RS) measurement and reporting.
CSI measurements include periodic CSI measurements, semi-persistent CSI measurements, and aperiodic CSI measurements. The CSI measurement is based on CSI-RS or Synchronization SIGNAL AND PBCH block (SSB) reference signals sent by the network side.
CSI reporting may be periodic reporting, semi-persistent reporting or aperiodic reporting, in particular:
Periodic CSI reporting (P-CSI): the UE performs CSI measurement and reporting according to a radio resource control (Radio Resource Control, RRC) configuration, transmitting only on a physical uplink control channel (Physical Uplink Control Channel, PUCCH).
Semi-persistent CSI reporting (SP-CSI): on the PUCCH or Physical Uplink shared channel (Physical Uplink SHARED CHANNEL, PUSCH). If the SP-CSI on PUCCH is the SP-CSI on PUCCH, after the UE receives the reference signal of RRC configuration and reports the configuration, the MAC CE is required to activate the SP-CSI measurement. Reporting of measurement results also requires MAC CE-activated SP-CSI reporting. If the channel state information is the SP-CSI on PUSCH, the difference is that the channel state information is reported by depending on downlink control information (Downlink Control Information, DCI) scheduling compared with the SP-CSI on PUCCH.
Aperiodic CSI report (AP-CSI): and transmitting on the PUSCH only, and triggering the measurement and the reporting of the CSI by the DCI.

The type field may also be per cell group, e.g. the first type field indicates the measurement combination type of all the serving cells of the primary cell group and the second type field indicates the measurement combination type of all the serving cells of the secondary cell group. The type field may also be a cell that is only a feature, e.g., the type field specifies the type of combination of measurements that is only used to indicate the primary and secondary cells that are reported.
In one embodiment of the application, the type field occupies 1 to a plurality of bytes, and the measurement quantity combination type is identified by a type identification, for example, 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, are respectively identified using identifications 1,2, 3,4, 5, 6, 7, 8 using 4 bits in total. When the type field of the MAC CE indicates 0001, the CSI measurement quantity field reported by the indicating terminal may carry CRI, RI, PMI, CQI measurement results. When the type field indicates 0011, the CSI measurement quantity field reported by the indicating terminal may carry CRI, RI, I1 and CQI measurement results. Wherein I1 represents feedback information of wideband PMI or PMI wideband information field (X1).
In an embodiment of the present application, whether the CSI measurement is reported is indicated by a bitmap. The bitmap may be specifically a CSI measurement sequence bit, for example, a bitmap 1100000 indicates that only RI and CQI are reported in RI, CQI, PMI, CRI, SSBRI, LI, L-RSRP/L1-SINR, and the type field may also be for each cell, may also be common to all cells, may also be only used for PCell or only used for SCell, and may also be only used for one cell group.
The MAC CE of the embodiment of the present application is specifically described below with reference to specific examples.
Example one: the first MAC CE carries CSI measurements of multiple serving cells of the secondary cell group.
For example, the MAC control element includes a MAC subheader and a MAC protocol data unit, the MAC subheader including an LCID field.
As shown in table 1-1, codepoint/Index is a first value of 35, i.e. is used to indicate that the MAC control element is the first MAC control element (multiple CSI report), and the MAC protocol data unit can carry CSI measurements of M serving cells of the secondary cell group (the serving cell sequence bit field occupies 1 byte), e.g. M is 8.
Codepoint/Index is a second value of 36, i.e. is used to indicate that the MAC control element is the first MAC control element (multiple CSI report), and the MAC protocol data unit is capable of carrying CSI measurements for N serving cells of the secondary cell group (serving cell sequence bit field occupies S bytes), e.g. S is 4, N is greater than 8.

Codepoint/Index | LCID values |
35 | Multiple CSI reporting (one oct Ci) |
36 | Multiple CSI reporting (S ottet Ci) |
For example, as shown in tables 1-2, the MAC control element includes a MAC subheader and a MAC protocol data element, the MAC subheader includes eLCID fields, and the eLCID fields include a first parameter Codepoint and a second parameter Index. When Codepoint has a value of 0 and index has a value of 64, the MAC control unit is indicated to be a first MAC control unit (multiple CSI reports), and the MAC protocol data unit can carry CSI measurement results of M serving cells of the secondary cell group (the serving cell sequence bit field occupies 1 byte);
when Codepoint has a value of 1 and index has a value of 65, the MAC control element is indicated to be the first MAC control element (multiple CSI report), and the MAC protocol data unit can carry CSI measurement results of N serving cells of the secondary cell group (S bytes are occupied by the serving cell sequence bit field).
TABLE 1-2
Codepoint | Index | eLCID values |
0 | 64 | Multiple CSI reporting (one oct Ci) |
1 | 65 | Multiple CSI reporting (S ottet Ci) |
Assuming that the number of serving cells is not more than 8 at most, and according to a protocol convention or a network configuration, as shown in fig. 3, the CSI measurement result of each serving cell only reports RI and CQI, which occupy 1 and 4 bits, respectively. The information carried by the actual MAC CE, as shown in fig. 4, is the CSI measurement results of the serving cells with serving cell index numbers 7, 4 and 1. 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. Another implementation is to allow several bits of CSI measurement results of multiple cells to be carried in one byte, namely the last three bits of byte 2 are used to indicate the first 2 bits of RI and CQI of the secondary cell 4. Byte 3 carries the last 2 bits of the secondary cell 4 CQI and the 5 bits of secondary cell 1, the remaining one bit being the reserved bit, where byte 4 is not needed.
As shown in fig. 5, the structure diagram includes a type field, where the value in the type field of the secondary cells 1 and 7 is1, which indicates that the reported measurement quantity is CRI-RI-PMI-CQI, and the value in the type field of the secondary cell 4 is 2, which indicates that the reported measurement quantity is CRI-RI-CQI.
Example two: the second MAC CE carries CSI measurements of one serving cell in the secondary cell group.
For example, the MAC control element includes a MAC subheader and a MAC protocol data unit, the MAC subheader including an LCID field. As shown in table 2-1, when Codepoint/Index is a third value, i.e. 37, the MAC control element is used to indicate that the MAC control element is a second MAC control element, and the MAC protocol data unit can carry the CSI measurement result of one serving cell of the secondary cell group.

Codepoint/Index | LCID values |
37 | Single-item CSI reporting |
For another example, the MAC control element includes a MAC subheader and a MAC protocol data unit, the MAC subheader including eLCID fields, the eLCID fields containing a first parameter Codepoint and a second parameter Index. As shown in table 2-2, when Codepoint has a value of 2 and index has a value of 66, the MAC control element is indicated to be a second MAC control element, and the MAC protocol data unit can carry the CSI measurement result of one serving cell of the secondary cell group.

It is assumed that the protocol specifies or network configures the UE to report only spcell measurements. The network may also configure the terminal to report the CSI measurement result of a certain serving cell, for example, cell 2, and the UE only reports the CSI measurement result of the serving cell 2 in the second MAC CE. As to which measurement quantities are carried in the measurement results of the serving cell, the indication method in the multiple CSI reports may be used.
If the protocol commits to report RI, CQI, PMI and L1, the CSI measurement fields carried in the second MAC CE for the serving cell include RI, CQI, PMI and L1, as shown in fig. 6.
If the protocol does not agree on the type of CSI measurement for the UE to report to the serving cell, the UE may indicate that the measurement combination type is 1 in the type field, that is, CRI, RI, CQI, PMI that indicates that the UE reports spcell, as shown in fig. 7. Fig. 8 is a type field indicating whether various CSI measurement amounts are reported in the form of bitmap.
Example three: and reporting the SCG CSI measurement result in the process of executing random access on the SCG.
Step 1: the SCG is in a deactivated state, and the UE receives an SCG activation command;
Step 2: the UE initiates random access to SCG or PSCell, and carries the MAC CE or the RRC message in the random access process (for example, in msg 3);
example four: after activating SCG or completing random access, reporting SCG CSI measurement result.
Step 1: the UE receives an SCG activation command;
Step 2: the UE initiates random access in SCG or PScell;
step 3: upon completion of random access or upon activation of SCG:
a) If the UL resource for transmitting the MAC CE or the RRC message exists, the UE transmits the MAC CE or the RRC message;
b) If the UL resource of the MAC CE or the RRC message is not transmitted, the UE transmits a first request, where the first request is used to request the network side to allocate UL resources for transmitting the MAC CE or the RRC message, for example, transmit a scheduling request (Scheduling Request, SR).
C) After receiving a report command sent by the network side, the UE sends the MAC CE or the RRC message, and the report command instructs the UE to report the MAC CE or the RRC message.
Example five: and sending the SCG CSI measurement result through the main base station.
Step 1: the SCG is in a deactivated state, and the UE receives a report command from the main base station, wherein the report command can be generated by the main base station or generated by the auxiliary base station and is forwarded by the main base station;
step 2: and the UE sends the MAC CE or the RRC message to the master base station.
Step 3: if the report command is generated by the auxiliary base station, the report command can be forwarded to the auxiliary base station once the main base station receives the MAC CE or the RRC message.
According to the information reporting method, the Channel State Information (CSI) measurement result of the service cell of the terminal is carried by the MAC CE or RRC message, so that the reporting of the CSI measurement result in the SCG deactivation period can be realized, the base station can be helped to acquire the quality of the SCG service cell in time, and further, the data scheduling can be rapidly carried out after the SCG is activated.
