The execution subjects involved in the embodiments of the present disclosure include, but are not limited to, UEs such as mobile phone terminals that support cellular mobile communication using the new air interface NR, and base stations.

An application scenario of the embodiment of the present disclosure is that, since the value range of the H-SFN is 0-1023, 10 bits need to be used to represent different H-SFNs. How to carry 10 bits of H-SFN in a new air interface (NR, New Radio) is an urgent problem to be solved.

As shown in FIG. 2, this exemplary embodiment provides an information transmission method, and the information transmission method can be applied to a base station, including:

Step 201: Send indication information, wherein the indication information is different from the information bits carried by the system information block.

Here, the base station and the UE may communicate based on NR. The UE may use eDRX mode for data transmission.

The indication information may be broadcast downlink signaling, or may be downlink signaling unicast to the UE.

The indication that the information is different from the information bits carried by the system information block may include, but is not limited to: the indication information is different from the entire system information block, and/or the indication information is not part of the information in the system information block.

In this way, a new downlink indication information for carrying information is provided. When the base station sends information, one of the indication information or the system information block can be selected for sending, which improves the flexibility of the base station in selecting downlink signaling.

In one embodiment, as shown in FIG. 3, step 201 includes:

Step 2011: Send indication information carrying n bits of H-SFN, where n is a positive integer greater than or equal to 1 and less than or equal to 10, wherein the system information block carries the H-SFN bits other than the n bits of .

The value range of H-SFN is 0-1023, and 10 bits are required to represent different H-SFNs. The base station may divide the H-SFN into two parts, the first part has n bits and the second part has 10-n bits. The n bits of the first part can be bits in any position of the H-SFN. For example, the n bits of the first part can be the n bits of the high order of the H-SFN, or the n bits of the low order of the H-SFN. bit.

The base station can carry n bits in the indication information and send it to the UE, and carry the other 10-n bits in the downlink information different from the indication information. For example, the other 10-n bits can be carried in the downlink information. It is sent to the UE in the system information block. Here, the system message block may include but is not limited to: system message block 1 (SIB1, System Information Block 1).

In one embodiment, n is 1 or 2.

Exemplarily, the base station may carry 1 or 2 bits in the indication information and send it to the UE, and carry another 10-n bits in downlink information different from the indication information, such as SIB1, and send it to the UE. Here, the indication information may be broadcast downlink signaling or unicast downlink signaling. The reserved bits in the existing downlink signaling can be used to carry n bits, or new dedicated downlink signaling can be used to carry n bits.

In one embodiment, the sending the indication information carrying n bits of H-SFN includes:

The indication information carrying the n bits of the H-SFN is sent in response to communication using the new air interface NR.

Exemplarily, since there are not enough reserved bits in the MIB to carry n bits in NR communication, the base station may carry n bits through indication information different from the system information block.

In one embodiment, the time domain position of the indication information carrying n bits is before the system information block carrying the remaining 10-n bits.

The base station may first send the indication information carrying n bits, and then send the system information block carrying the remaining 10-n bits.

The UE may receive the indication information, and determine the n bits carried by the indication information from the indication information.

The UE may also receive the system information block, and determine the remaining 10-n bits carried by the system information block from the system information block.

In this way, for NR, the indication information different from the system information block carries n bits, and the system information block carries the remaining 10-n bits, so that the H-SFN is carried in the NR communication. Then, the UE can perform synchronization based on the super system frame to meet the requirements of a longer paging cycle and a DRX cycle, thereby reducing the power consumption of the UE and saving power.

The indication information carrying n consecutive bits of the H-SFN lower bits is sent.

Here, the indication information may carry the lower n bits of the H-SFN, for example, the indication information may carry the lowest bit of the H-SFN, or the lower 2 bits.

A superframe occupies 10.24s in the time domain, that is, the lowest bit of the H-SFN can identify plus or minus 10.24 seconds; the two lowest two bits can identify plus or minus 20.56 seconds.

For the case where the UE is configured with the eDRX mode, if the duration identified by n bits is greater than or equal to the longest eDRX cycle, the UE only needs to determine the synchronization offset from the lower n bits of the H-SFN carried in the indication information to complete the synchronization. It is no longer necessary to read the remaining H-SFN bits in the system information block. Thus, the power consumption generated by reading the system information block is reduced, thereby saving power.

Exemplarily, when the longest eDRX cycle does not exceed plus or minus 10.24 seconds, the UE may only need to determine the synchronization offset from the lowest bit of the H-SFN carried in the indication information to complete synchronization, and n may be selected as 1. When the longest eDRX cycle does not exceed plus or minus 20.48 seconds, the UE only needs to determine the synchronization deviation from the lower two bits of the H-SFN carried in the indication information, and then complete the synchronization, and n can be selected as 2.

The base station can adjust n based on actual requirements, such as the eDRX cycle. That is, the base station can adjust the number of bits of the H-SFN carried in the indication information and the number of bits of the H-SFN in the system information block based on actual requirements.

In this way, by carrying the n low-order bits in the indication information, when the UE only needs to use the low-order bits of the H-SFN for synchronization, it can only read the indication information and no longer read the system information block, thereby reducing read Take the energy consumption generated by the system information block to save power.

In one embodiment, in response to using frequency band 1 (FR1, Frequency Range 1) for data transmission, the sending of the indication information carrying n bits of H-SFN includes:

sending synchronization signal block index (SSB Index) indication information, wherein the reserved bits of the SSB Index indication information carry the n bits of the H-SFN;

or,

Send the remaining minimum system information control resource set (RMSI CORSET, Remain System Information Control Resource Set) indication information, wherein the reserved bits of the RMSI CORSET indication information carry the n bits of the H-SFN.

The SSB Index indication information may be located in three bits of A+5, A+6 and A+7 on the 8-bit additional payload on the PBCH. Here, A+6 and/or A+7 may be used to carry n bits of H-FSN. When n is 1, it can be carried by A+6 or A+7, and when n is 2, it can be carried by A+6 and A+7.

In response to data communication between the base station and the UE based on FR1, the UE only needs to read the MIB DMRS to obtain the SSB Index indication information, that is, to obtain n bits of the H-FSN. Therefore, when the base station and the UE conduct data communication based on FR1, the The n bits of the H-FSN are carried in the SSB Index indication information, so that the MIB can not be read, thereby reducing the energy consumption generated by reading the MIB, thereby saving power.

If the SSB Index indication information is unavailable, the n bits of the H-FSN can be carried by the RMSI CORSET indication information. The RMSI CORSET indication information is in PDCCH-ConfigCommon and can be used to indicate the RMSI CORSET configuration. The reserved bits in the RMSI CORSET indication information can be used to carry n bits of the H-FSN. When n is 1, one bit in the RMSI CORSET indication information can be used to carry 1 bit of H-FSN, and when n is 2, two bits in the RMSI CORSET indication information can be used to carry two H-FSN bits. bits.

The time domain position of the SSB Index indication information and RMSI CORSET indication information is located before the time domain position of the system information block. Therefore, when the UE only needs to read n bits of the H-FSN, the UE can read the SSB Index indication information and/or Or read from the RMSI CORSET instruction information, and no longer read the system information block, thereby reducing the energy consumption generated by reading the system information block, thereby saving power.

In an embodiment, the sending RMSI CORSET indication information, wherein the reserved bits of the RMSI CORSET indication information carry the n bits of the H-SFN, including:

The reserved bits sent in the controlResourceSetZero field carry the n-bit RMSI CORSET indication information.

There are two ways to indicate the information of RMSI CORSET: ControlResourceSet or ControlResourceSetZero. The ControlResourceSetZero field has reserved bits, therefore, the reserved bits of the ControlResourceSetZero field can be used to carry n bits of the H-FSN.

In one embodiment, in response to using frequency band 2 (FR2, Frequency Range 2) for data transmission, the sending of the indication information carrying n bits of H-SFN includes:

Sending search space (SearchSpace) indication information, wherein the reserved bits of the SearchSpace indication information carry the n bits of the H-SFN.

The SearchSpace indication information in PDCCH-ConfigCommon can be used to indicate the Search Space configuration, and the reserved bits of the SearchSpace indication information can be used to carry n bits of the H-FSN.

The time domain position of the SearchSpace indication information is located before the time domain position of the system information block. Therefore, when the UE only needs to read n bits of the H-FSN, the UE can read it from the SearchSpace indication information and no longer reads the system information. information blocks, thereby reducing the energy consumption of reading system information blocks, thereby saving power.

In one embodiment, the sending of the SearchSpace indication information, wherein the reserved bits of the SearchSpace indication information carry the n bits of the H-SFN, including:

The reserved bits in the SearchSpaceZero field carry the SearchSpace indication information of the n bits.

There are two types of SearchSpace indication information, one of which is SearchSpaceZero. The SearchSpaceZeroo field has reserved bits, therefore, the reserved bits of the SearchSpaceZero field can be used to carry n bits of the H-FSN.

For FR2, because the UE must read the MIB, and SSB and Coreset#0 are FDM modes, there are reserved bits in searchSpaceZero, and n bits of HSFN can be placed on the last n reserved bits in searchSpaceZero.

Send a Tracking Reference Signal (TRS, Tracking Reference Signal) and/or a Channel State Indication Reference Signal (CSI-RS, Channel State Information Reference Signal) carrying the n bits of the H-SFN.

TRS or CSI-RS can assist UE in synchronization. TRS or CSI-RS can assist UEs in idle or inactive state to perform synchronization.

The n bits of the H-FSN can be carried by TRS or CSI-RS. When n is 1, one bit of TRS or CSI-RS can be used to carry 1 bit of H-FSN; when n is 2, two bits of TRS or CSI-RS can be used to carry H-FSN. two bits.

The time domain position of the TRS or CSI-RS can be configured to be located before the time domain position of the system information block. Therefore, when the UE only needs to read n bits of the H-FSN, the UE can read from the TRS or CSI-RS. , the system information block is no longer read, thereby reducing the energy consumption generated by reading the system information block, thereby saving power.

In one embodiment, the method further includes:

The TRS or CSI-RS carrying the lower 4th to 3rd+mth bits of the SFN is transmitted, where m is a positive integer greater than or equal to 1 and less than or equal to 3.

At present, the DMRS of the SSB carries the lower 3 bits of the SFN, and the MIB carries the remaining bits of the SFN. Under FR1, it is possible to synchronize without reading the information in the MIB. In response to using FR2 for data communication, the lower 4th to 3rd+mth bits of the SFN also need to read the MIB. Here, the lower 3+m bits of the SFN can be carried in the TRS or CSI-RS. In this way, in response to using FR2 for data communication, it is not necessary to read the MIB, and only the SFN carried in the TRS or CSI-RS can be read. The 4th to 3rd+mth bits of the lower order can complete the synchronization. That is, the UE combines the low-order n bits of the HSFN, the low-order 4th to 3rd+m bits of the SFN carried in the TRS or CSI-RS, and the low-order 3 bits of the SFN of the DMRS in the SSB. Perform frame synchronization to avoid reading MIB information. Thus, the power consumption generated by reading the MIB is reduced, thereby saving power.

When the base station has the information to be sent, it can select one of the indication information or the system information block to send, which improves the flexibility of the base station to select downlink signaling.

The base station can carry n bits in the indication information and send it to the UE, and carry the other 10-n bits in the downlink information different from the indication information. For example, the other 10-n bits can be carried in the downlink information. It is sent to the UE in the system information block. Here, the system message block may include but is not limited to: system message block 1 (SIB1, System Information Block 1). In one embodiment, n is 1 or 2.
