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. In a new air interface (NR, New Radio), a downlink reference signal of the base station or the like can be used to carry at least 1 bit of the 10 bits of the H-SFN.

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 indicating the state that the reference signal carries the H-SFN.

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 multiple parts, for example, 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. Here, n may be less than or equal to the number of bits of the H-SFN, that is, n may be a positive integer less than or equal to 10.

The base station can carry n bits in the reference signal and send it to the UE, and carry the other 10-n bits in downlink information different from the indication information, for example, the other 10-n bits can carry Sent to the UE in a system message.

The base station may also carry the entire H-SFN in a reference signal and send it to the UE without dividing the H-SFN, or carry the entire H-SFN in a system message and send it to the UE.

In one embodiment, the reference signal includes: Tracking Reference Signal (TRS, Tracking Reference Signal) or Channel State Indication Reference Signal (CSI-RS, Channel State Information Reference Signal).

The base station may carry one or more bits of the H-SFN through TRS or CSI-RS. The TRS or CRS can be configured to be closer to the paging occasion PO, while the original synchronization signal block SSB is farther away from the PO, so the user needs to wake up a long time in advance to synchronize with the SSB. After using TRS or CRS, you can wake up later, so you can save more power.

In an embodiment, the TRS or CSI-RS is at least used for downlink synchronization for user equipment UEs in an idle state or an inactive state.

Here, the TRS or CSI-RS may be the TRS or CSI-RS shared by UEs in idle state or inactive state and shared with UEs in connected state. The idle state UE or the inactive state UE, and the connected state UE can monitor the TRS or CSI-RS at the shared TRS or CSI-RS timing.

Here, the state that the reference signal carries the H-SFN can be at least used for the UE to determine the location of the bits of the H-SFN, and the state that the reference signal carries the H-SFN includes, but is not limited to, whether the reference signal carries the H-SFN; - The position of the SFN in the reference signal; whether the reference signal carries all the bits of the H-SFN, etc.

In this way, the base station can explicitly indicate the state that the reference signal carries H-SFN through the indication information. The indication information informs the UE, which improves the flexibility of the reference signal to carry the H-SFN. On the other hand, the UE can determine the position of reading the H-SFN based on the indication information, so as to reduce the reading error caused by the uncertainty of the position of the H-SFN, and improve the efficiency of reading the H-SFN.

In an embodiment, the indication information is used to indicate whether the reference signal carries at least one bit of the H-SFN.

In response to the base station carrying at least one bit of the H-SFN in the reference signal, the base station may send indication information, indicating that the reference information carries at least one bit of the H-SFN.

In response to the reference signal not carrying the bits of the H-SFN, the base station may send indication information indicating that the reference information does not carry the bits of the H-SFN.

The UE may determine whether the reference signal carries at least one bit of the H-SFN based on the indication information, and if so, it may determine at least one bit of the H-SFN from the reference signal, otherwise, it may be based on a direct predetermined or The agreement of the communication protocol to determine the H-SFN from other information, such as system messages.

In an embodiment, the indication information is used to indicate the number of bits of the H-SFN carried by the reference signal.

In response to the base station carrying at least one bit of the H-SFN in the reference signal, the base station may send indication information indicating the number of bits carrying the H-SFN in the reference information.

In one embodiment, the number of bits that the reference signal carries the H-SFN may implicitly indicate that the reference signal carries the bits of the H-SFN.

In an embodiment, the indication information is used to indicate the number of low-order bits of the H-SFN carried by the reference signal.

Here, the number of bits of the H-SFN carried by the reference signal indicated by the indication information may be the number of bits of the lower order of the H-SFN. For example, the indication information may indicate that the lower 1 bit of the H-SFN is carried, or the lower 2 bits bit.

In some scenarios, the UE only needs the lowest n bits for synchronization. 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 Extended Discontinuous Reception (eDRX, Extended Discontinuous Reception) mode, if the duration identified by n bits is greater than or equal to the longest eDRX cycle, the UE may only need the H-SFN carried in the indication information. The lower n bits of , determine the synchronization deviation, and then complete the synchronization. It is no longer necessary to read the remaining H-SFN bits in SIB1. Thus, the power consumption generated by reading the SIB1 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 offset 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 UE may determine the number of low-order bits of the H-SFN carried by the reference signal based on the indication information, and then determine the corresponding number of low-order bits in the reference signal.

Further, the N number of digits can be agreed in advance by agreement.

3. The network side explicitly informs the terminal whether the reference symbols sent by it carry the H-SFN superframe information. The indication needs to be notified to the user through broadcast signaling or unicast:

a) Mode 1: As an embodiment, the indication information may be carried together in the configuration of the reference symbol.

b) Mode 2: As an embodiment, the indication information may not be sent together with the reference symbol configuration, that is, sent separately.

c) Mode 3: see description in 4b).

4. If the network side notifies the terminal that the reference symbols it sends carry H-SFN superframe information, the available status of the reference symbols needs to be notified to the user:

a) As an embodiment, the network notifies the terminal that the available state of the TRS or CRS is represented as the activation state of the resource:

The active state: that is, the configuration of the resource exists reasonably, and the network is actually sending the specific reference signal corresponding to the resource; at this time, it is available to the terminal; the network expects the terminal to use it.

Inactive state: that is, the configuration of the resource does not exist reasonably, or the configuration of the resource exists reasonably but the network is not actually sending the specific reference signal corresponding to the resource; at this time, it is unavailable for the terminal; The network does not expect end use.

b) As an embodiment, the network notifies the terminal of the available status of the reference symbols through broadcast signaling or dedicated signaling (RRC message or DCI), and at the same time carries the information in 3 to inform the terminal whether the reference symbols it sends carry H- Indication information of SFN superframe information.

5. When the terminal obtains that the reference symbol is currently active and learns that the reference symbol carries superframe information, it can obtain the H-SFN information by using the information carried in the reference symbol;

a) Going a step further: the terminal obtains the complete H-SFNbit from it; (the advantage of this is that the terminal does not need to obtain the superframe information from the system message).

b) Further, the terminal obtains the lower N H-SFN bits from the reference symbol; the remaining bits need to be continuously obtained from the system message.

As an embodiment, the system message is an MIB or SIB message. In this way, the clock drift of the terminal is within the range of N H-SFN bits and does not need to obtain the superframe information from the system message.

6. When the terminal obtains that the TRS or CRS is currently in the deactivated state, it needs to fall back to the information carried in the system message to obtain the H-SFN information and synchronize with the network; (it does not take effect during deactivation/activation).

7. Based on 1, the network side displays and informs the terminal whether or not the H-SFN superframe information is carried in the reference symbols issued by the network side, which is only quoted in the scenario where the network supports eDRX.

a) As an embodiment, the eDRX supported by the network includes an eDRX in an idle state or an eDRX in an inactive state.
