The execution subject that this disclosed embodiment relates to includes but not limited to: a UE such as a mobile phone terminal supporting cellular mobile communication, and a base station.

One application scenario of the embodiment of the present disclosure is that, since the range of the H-SFN is 0 to 1023, 10 bits are required to represent different H-SFNs. At least 1 bit of 10 bits of the H-SFN can be carried in a New air interface (NR, New Radio) by using a reference signal of a base station downlink or the like.

As shown in fig. 2, the present exemplary embodiment provides an information transmission method, which may be applied in a base station, and includes:

step 201: and sending indication information indicating that the reference signal carries the state of the H-SFN.

The range of H-SFN values is 0-1023, and 10 bits are needed to represent different H-SFN.

The base station may divide the H-SFN into multiple portions, e.g., the base station may divide the H-SFN into two portions, a first portion having n bits and a second portion having 10-n bits. The n bits of the first portion may be any position of the H-SFN, for example, the n bits of the first portion may be the upper n bits of the H-SFN or the lower n bits of the H-SFN. Here, n may be less than or equal to the number of bits of the H-SFN, i.e. n may be a positive integer less than or equal to 10.

The base station may carry n bits in the reference signal 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 may be carried in a system message to the UE.

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

In one embodiment, the reference signal comprises: tracking Reference Signal (TRS) or Channel State indication Reference Signal (CSI-RS).

The base station may carry one or more bits of the H-SFN via the TRS or CSI-RS. The TRS or CRS may be configured closer to the PO time of the paging occasion, while the original synchronization signal block SSB is located further away from the PO, so the user needs to wake up and SSB synchronize very early. After the TRS or CRS is used, the TRS or CRS may wake up later, thereby saving more power.

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

Here, the TRS or CSI-RS may be a TRS or CSI-RS shared with a connected-state UE for an idle-state UE or an inactive-state UE. The idle state UE or the inactive state UE and the connected state UE can monitor the TRS or the CSI-RS at the shared TRS or CSI-RS occasion.

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

Therefore, the base station can explicitly indicate the state of the H-SFN carried by the reference signal through the indication information, on one hand, the base station can flexibly select whether the H-SFN carried by the reference signal, the bit position of the H-SFN and the like are carried by the reference signal, and informs the UE through the indication information, so that the flexibility of the H-SFN carried by the reference signal is improved. On the other hand, the UE can determine the position for reading the H-SFN based on the indication information, so that reading errors caused by the fact that the position where the H-SFN is not determined are reduced, and the efficiency for reading the H-SFN is improved.

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 the at least one bit of the H-SFN.

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

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, may determine the at least one bit of the H-SFN from the reference signal, otherwise, may determine the H-SFN from other information, such as a system message, based on a predetermined or communication protocol agreement between the base station and the UE.

In one 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.

The UE may determine, based on the indication information, a number of bits of the H-SFN carried by the reference signal, and then determine a corresponding number of bits from the reference signal.

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

In one embodiment, the indication information is used to indicate the number of lower-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 bits of the H-SFN, for example, the indication information may indicate the lower 1 bits or the lower 2 bits of the H-SFN.

In some scenarios, the UE only needs the lowest n bits for synchronization. The time domain of a superframe occupies 10.24s, namely the lowest bit of the H-SFN can be marked for plus or minus 10.24 s; the two bits of the lowest two bits are plus or minus 20.56 seconds that can be identified.

For the case that the UE configures Extended Discontinuous Reception (eDRX) mode, if the duration identified by n bits is greater than or equal to the longest eDRX cycle, the UE may only need to determine the synchronization deviation from the low n bits of the H-SFN carried by the indication information, thereby completing synchronization. It is no longer necessary to read the bits of the remaining H-SFN in SIB 1. Thereby reducing the power consumption resulting from reading the SIB1 and thereby saving power.

For example, when the longest eDRX cycle does not exceed plus or minus 10.24 seconds, the UE may only need to determine the synchronization deviation from the lowest bit of the H-SFN carried by the indication information to complete synchronization, and n may be selected to be 1. And when the longest eDRX period does not exceed plus or minus 20.48 seconds, the UE can only determine the synchronization deviation from the lower two bits of the H-SFN carried by the indication information to complete the synchronization, and n can be selected to be 2.

The UE may determine, based on the indication information, a number of lower-order bits of the H-SFN carried by the reference signal, and then determine a corresponding number of lower-order bits in the reference signal.

In one embodiment, the sending the indication information indicating the state of the H-SFN carried by the reference signal includes at least one of:

broadcasting the indication information indicating that the reference signal carries the state of the H-SFN;

unicast indicates that the reference signal carries the indication information of the state of the H-SFN.

The base station may transmit the indication information to the UE in the form of broadcast and/or unicast.

For example, the base station may carry the indication information in a broadcasted message. The UE may determine from the broadcasted message that the reference signal carries indication information of the state of the H-SFN.

The base station may carry the indication information in the existing unicast signaling or in the newly added dedicated unicast signaling, and send the indication information to the UE. The UE may determine from the unicast signaling that the reference signal carries indication information of the state of the H-SFN.

In an embodiment, the sending the indication information indicating the state of the H-SFN carried by the reference signal includes:

sending a first downlink message carrying the configuration information of the reference signal and the indication information at the same time; wherein the configuration information of the reference signal is at least used for indicating the transmission resource of the reference signal;

or,

and sending a second downlink message carrying the indication information, wherein the second downlink message is different from a third downlink message carrying the configuration information of the reference signal.

The indication information and the configuration information of the reference signal may be carried in the same downlink message and sent to the UE. After receiving the downlink message, the UE may determine at least transmission resources of the reference signal based on the configuration information of the reference signal, and may determine a state of the reference signal carrying the H-SFN based on the indication information. Therefore, the utilization efficiency of the downlink message is improved.

And in response to the indication information indicating that the reference signal carries at least one bit of the H-SFN and/or the indication information indicating that the reference signal carries the number of bits of the H-SFN, the UE determines the bits of the H-SFN from the reference information.

In response to the indication information indicating that the reference signal does not carry at least one bit of the H-SFN, the UE determines bits of the H-SFN from other information, such as a system message.

The indication information and the configuration information of the reference signal may also be carried in different downlink messages and sent to the UE. After receiving a downlink message, the UE may determine at least transmission resources of the reference signal based on the configuration information of the reference signal. After receiving another downlink message, the UE may determine a state of the H-SFN carried by the reference signal based on the indication information. Therefore, the flexibility of carrying the configuration information and the indication information of the reference signal can be improved.

Here, the downlink message includes, but is not limited to: a Radio Resource Control (RRC) message.

In one embodiment, the method further comprises:

and sending reference signal activation indication information in response to the reference signal carrying at least one bit of the H-SFN, wherein the reference signal activation indication information is used for indicating the activation state of the reference signal, namely whether the reference signal is activated or not.

In response to the base station notifying the UE of at least one bit carrying the H-SFN in the reference signal transmitted by the UE, the base station also needs to notify the UE of the available state of the reference signal in advance through the reference signal activation indication information.

The reference signal activation indication information indicates an available state of a reference signal, such as a TRS or a CRS, as an activation state of the resource:

the reference signal activation indication information may indicate that the reference signal is in an activated state, the configuration of the reference signal resource is reasonably present, and the network actually sends the reference signal corresponding to the resource; at this point, the reference signal is available to the UE; the network expects the UE to receive the reference signal using the resource of the reference signal.

In response to the indication information of reference signal activation indicating that the reference signal is in an activated state, the UE may monitor the reference signal and determine a state of the H-SFN carried by the reference signal based on the indication information carried by the reference signal.

The reference signal activation indication information may indicate that the reference signal is in an inactive state, the configuration of the reference signal resource is unreasonable, or the configuration of the resource is reasonable but the network does not actually send the reference signal corresponding to the resource; at this time, the reference signal is unavailable for the terminal; the network does not expect the terminal to use the reference signal.

In response to the reference signal activation indication information indicating that the reference signal is inactive, the UE may determine the H-SFN based on other information, such as system information.

In one embodiment, the sending of the reference signal activation indication information includes at least one of:

broadcasting a signaling carrying the reference signal activation indication information;

sending RRC information carrying the reference signal activation indication information;

and sending Downlink Control Information (DCI) carrying the reference signal activation indication Information.

The base station may carry the reference signal activation indication information through broadcast information, for example, by carrying the reference signal activation indication information in a system message.

The base station may also carry the reference signal activation indication information through dedicated signaling, such as RRC message or DCI.

broadcasting a signaling carrying the indication information and the reference signal activation indication information;

sending the RRC information carrying the indication information and the reference signal activation indication information;

and sending the DCI carrying the indication information and the reference signal activation indication information.

The base station may also carry indication information while notifying the UE of the activation state of the reference signal through broadcast signaling or dedicated signaling, such as RRC message or DCI, so as to notify the UE whether the reference signal sent by the base station carries at least one bit of the H-SFN.

Therefore, the information amount carried by broadcast signaling or special signaling, such as RRC message or DCI, can be increased, and the transmission efficiency can be increased.

In one embodiment, the method further comprises:

and transmitting the reference signal carrying n bits of the H-SFN, wherein n is a positive integer which is greater than or equal to 1 and less than or equal to m, and m is the number of the bits of the H-SFN.

The H-SFN is split into two parts in response to the base station, the first part having n bits and the second part having 10-n bits. The n bits of the first portion may be any position of the H-SFN, for example, the n bits of the first portion may be the upper n bits of the H-SFN or the lower n bits of the H-SFN. The base station may carry the n bits in the reference information to the UE and carry the other 10-n bits in the downlink information different from the indication information, e.g., the other 10-n bits may be carried in the SIB1 to the UE.

The base station can also transmit 10 bits of the H-SFN to the UE by carrying the bits in the reference signal.

Here, the reference signal may be a TRS or a CSI-RS, which may be a shared TRS or CSI-RS, i.e., a reference signal that may be simultaneously used in a connected state, an idle state, or an active state.

In an embodiment, the sending indication information indicating the state of the H-SFN carried by the reference signal includes:

sending the indication information indicating the state of the H-SFN carried by the reference signal in response to the operation in the eDRX mode.

In eDRX mode, eDRX cycle is long and a super system frame needs to be used for synchronization. As such, in eDRX mode, an H-SFN needs to be indicated. The base station may indicate the status of the bits of the H-SFN through the indication information.

In one embodiment, the eDRX mode includes:

an idle state eDRX mode or an inactive state eDRX mode.

The eDRX mode may be applied to an idle state UE or an inactive state UE. In response to the UE being in an idle state or an active state and operating in eDRX mode, the UE and the base station are synchronized using a super system frame. The base station can indicate the state of the bit of the H-SFN through the indication information.

As shown in fig. 3, the present exemplary embodiment provides an information transmission method, which may be applied to a user equipment, and includes:

step 301: receiving indication information;

step 302: and determining the state of the H-SFN carried by the reference signal according to the indication information.

The base station may divide the H-SFN into multiple parts, e.g., the base station may divide the H-SFN into two parts, a first part having n bits and a second part having 10-n bits. The n bits of the first portion may be any position of the H-SFN, for example, the n bits of the first portion may be the upper n bits of the H-SFN or the lower n bits of the H-SFN. Here, n may be less than or equal to the number of bits of the H-SFN, i.e. n may be a positive integer less than or equal to 10.

In one embodiment, the reference signal comprises: TRS or CSI-RS.

The base station may carry one or more bits of the H-SFN through the TRS or the CSI-RS. The TRS or CRS may be configured closer to the PO time of the paging occasion, while the original SSB is further away from the PO location, so the user needs to wake up well in advance and synchronize with the SSB. After the TRS or CRS is used, the TRS or CRS may wake up later, thereby saving more power.

Here, the TRS or CSI-RS may be a TRS or CSI-RS shared with a connected-state UE for an idle-state UE or an inactive-state UE. The idle state UE or the inactive state UE, and the connected state UE may monitor the TRS or CSI-RS at a shared TRS or CSI-RS occasion.

In an embodiment, the determining, according to the indication information, a state that a reference signal carries an H-SFN includes:

and determining whether the reference signal carries at least one bit of the H-SFN or not according to the indication information.

and determining the number of the bits of the H-SFN carried by the reference signal according to the indication information.

In an embodiment, the determining, according to the indication information, the number of bits of the H-SFN carried by the reference signal includes:

and determining the number of the bits of the low order bits of the H-SFN carried by the reference signal according to the indication information.

In some scenarios, the UE only needs the lowest n bits for synchronization. The superframe occupies 10.24s in time domain, namely the lowest bit of the H-SFN can be marked for plus or minus 10.24 s; the two bits of the lowest two bits are plus or minus 20.56 seconds that can be identified.

For the situation that the UE configures the eDRX mode, if the duration identified by the n bits is greater than or equal to the longest eDRX cycle, the UE may determine the synchronization deviation only from the low n bits of the H-SFN carried by the indication information, thereby completing the synchronization. It is no longer necessary to read the bits of the remaining H-SFN in SIB 1. Thereby reducing the power consumption resulting from reading the SIB1 and thereby saving power.

In one embodiment, the receiving indication information includes at least one of:

receiving the indication information broadcasted;

receiving the indication information of unicast.

The base station may carry the indication information in the existing unicast signaling or in the newly added dedicated unicast signaling, and send the indication information to the UE. The UE may determine from the unicast signaling that the reference signal carries information indicative of the state of the H-SFN.

In one embodiment, the receiving the indication information includes:

receiving a first downlink message carrying configuration information of the reference signal and the indication information at the same time; wherein the configuration information of the reference signal is at least used for indicating the transmission resource of the reference signal;

or,

receiving a second downlink message carrying the indication information, wherein the second downlink message is different from a third downlink message carrying the configuration information of the reference signal.

Further: the reference symbol is a TRS or CSI-RS for assisting the non-connected state user to carry out synchronization.

2. The network side explicitly informs the terminal whether the reference symbol sent by the terminal carries H-SFN superframe information or not, and the parameter comprises one of the following parameters:

a) presence/absence of H-SFN superframe information.

b) The reference symbols carry part of the bit number N of the H-SFN superframe information.

As an embodiment, the superframe information carried in the reference symbols is the low N bits of the H-SFN index (index).

Further, the N number of bits may be agreed upon in advance.

3. The network side explicitly informs the terminal whether the reference symbol sent by the terminal carries the indication of the H-SFN superframe information or not, and the indication needs to inform the user through a broadcast signaling or a unicast mode:

a) mode 1: as an example, the indication information may be carried together in the configuration of the reference symbols.

b) Mode 2: as an embodiment, the indication information may not be transmitted together with the reference symbol, i.e. separately transmitted.

c) Mode 3: see 4 b).

4. If the network side notifies the terminal that the reference symbol issued by the network side carries H-SFN superframe information, the available state of the reference symbol needs to notify the user:

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

wherein the activation state: that is, the configuration of the resource is reasonable, and the network actually transmits the specific reference signal corresponding to the resource; at this point, it is available to the terminal; the network is intended for the end use.

Wherein the inactive state: that is, the configuration of the resource is unreasonable, or the configuration of the resource is reasonable but the network does not actually transmit the specific reference signal corresponding to the resource; at this time, the terminal is unavailable; the network is not intended for end use.

b) As an embodiment, the network notifies the terminal of the available state of the reference symbol through broadcast signaling or dedicated signaling (RRC message or DCI), and at the same time, carries indication information in 3 that notifies the terminal whether the reference symbol sent by the terminal carries H-SFN superframe information.

5. When the terminal acquires that the reference symbol is in an active state at present and learns that the reference symbol carries superframe information, the terminal can acquire H-SFN information by using the information carried in the reference symbol;

a) further: the terminal acquires all complete H-SFNbit from the terminal; (this has the advantage that the terminal does not need to obtain superframe information in system messages).

b) Further, the terminal acquires the low N H-SFNbits from the reference symbols; the remaining bits need to continue to be retrieved from the system message.

In one embodiment, the system message is a MIB or SIB message. Therefore, the clock drift of the terminal does not need to acquire superframe information from the system message within the range of N H-SFN bits.

6. When a terminal acquires that a TRS or a CRS is in a deactivation state at present, information carried in a system message needs to be returned to acquire H-SFN information and synchronize with a network; (not effective at deactivation/activation).

7. Based on 1, the network side displays and informs the terminal whether the reference symbol issued by the terminal carries H-SFN superframe information and only refers to the scene that the network supports eDRX.

a) The network supports eDRX as an embodiment, and the eDRX includes idle eDRX or inactive eDRX.
