Abstract
Description

[0002] The time unit for synchronization between the user equipment (UE) and the base station is the system frame. The UE is synchronized based on the system frame number (SFN). One SFN is 10ms. The SFN value range is 0-1023. When SFN reaches 1023, it restarts from 0. The maximum SFN period is 1024 system frames, that is, 10.24 seconds. The paging cycle and DRX cycle need to be less than 10.24 seconds.
[0003] With the increasing demand for power saving, 10.24 seconds cannot meet the requirements of paging cycle, DRX cycle and other cycles. Therefore, a new super system frame is defined. UE is synchronized based on the super system frame number (H-SFN, H System Frame Number). One super system frame corresponds to 1024 system frames, that is, one super frame is equal to 10.24s. The value range of H-SFN is 0-1023. The maximum period of H-SFN is 1024 H-SFNs, that is, 2.9127 hours. Summary of the invention

[0029] Please refer to Figure 1 , which shows a schematic diagram of the structure of a wireless communication system provided by an embodiment of the present disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of terminals 11 and a plurality of base stations 12 .
[0030] Among them, the terminal 11 can be a device that provides voice and / or data connectivity to the user. The terminal 11 can communicate with one or more core networks via a radio access network (RAN). The terminal 11 can be an Internet of Things terminal, such as a sensor device, a mobile phone (or a "cellular" phone), and a computer with an Internet of Things terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-built-in or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment (UE).

Alternatively, the terminal 11 may also be a roadside device, for example, a street lamp, a traffic light or other roadside device with a wireless communication function.
[0031] The base station 12 may be a network-side device in a wireless communication system. The wireless communication system may be a fourth generation mobile communication technology (4G) system, also known as a long term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system.

Alternatively, the base station 12 can also be a base station (gNB) adopting a centralized distributed architecture in the 5G system. When the base station 12 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU).

The specific implementation method of the base station 12 is not limited in the embodiment of the present disclosure.
[0033] A wireless connection can be established between the base station 12 and the terminal 11 through a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

[0036] Several base stations 12 are respectively connected to a network management device 13. The network management device 13 may be a core network device in a wireless communication system. For example, the network management device 13 may be a mobility management entity (MME) in an evolved packet core (EPC). Alternatively, the network management device may be other core network devices, such as a serving gateway (SGW), a public data network gateway (PGW), a policy and charging rules function (PCRF), or a home subscriber server (HSS). The implementation form of the network management device 13 is not limited in the embodiments of the present disclosure.
[0037] The execution entities involved in the embodiments of the present disclosure include, but are not limited to: UEs such as mobile phone terminals supporting cellular mobile communications, and base stations, etc.
[0038] One application scenario of the disclosed embodiment is that, since the H-SFN value range is 0-1023, 10 bits are needed to represent different H-SFNs. In the new radio (NR, New Radio), at least one of the 10 bits of H-SFN can be carried by using a base station downlink reference signal or the like.
[0039] like Figure 2 As shown, this exemplary embodiment provides an information transmission method, which can be applied to a base station, including:
[0040] Step 201: Send indication information indicating the state of a reference signal carrying H-SFN.
[0041] The value range of H-SFN is 0-1023, and 10 bits are needed to represent different H-SFNs.
[0042] The base station may divide the H-SFN into a plurality of parts. For example, the base station may divide the H-SFN into two parts, the first part having n bits and the second part having 10-n bits. The n bits of the first part may be bits at any position of the H-SFN. For example, the n bits of the first part may be n bits of the high position of the H-SFN or n bits of the low position of the H-SFN. 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.
[0043] The base station may carry n bits in a 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 may be carried in a system message and sent to the UE.
[0044] The base station may also not divide the H-SFN, but carry the entire H-SFN in a reference signal and send it to the UE, or carry the entire H-SFN in a system message and send it to the UE.
[0045] In one embodiment, the reference signal includes: a tracking reference signal (TRS, Tracking Reference Signal) or a channel state indication reference signal (CSI-RS, Channel State Information Reference Signal).
[0046] The base station can carry one or more bits of H-SFN through TRS or CSI-RS. TRS or CRS can be configured closer to the paging opportunity PO time, while the original synchronization signal block SSB is far away from the PO position, so the user needs to wake up a long time in advance to synchronize with the SSB. After using TRS or CRS, it can wake up later, so it can save more power.
[0047] In one embodiment, the TRS or CSI-RS is at least used for downlink synchronization of a user equipment UE in an idle state or an inactive state.
[0048] Here, the TRS or CSI-RS may be a TRS or CSI-RS shared by an idle UE or an inactive UE and a connected UE. The idle UE or the inactive UE and the connected UE may monitor the TRS or CSI-RS at the shared TRS or CSI-RS timing.
[0049] Here, the state of the reference signal carrying H-SFN can be at least used for the UE to determine the position of the bit of H-SFN. The state of the reference signal carrying H-SFN includes but is not limited to whether the reference signal carries H-SFN; the position of carrying H-SFN in the reference signal; whether the reference signal carries all bits of H-SFN, etc.
[0050] In this way, the base station can explicitly indicate the state of the reference signal carrying H-SFN through the indication information. On the one hand, the base station can flexibly choose whether to carry the H-SFN state in the reference signal, as well as the bit position carrying H-SFN, and inform the UE through the indication information, thereby improving the flexibility of the reference signal carrying H-SFN. On the other hand, the UE can determine the location of reading H-SFN based on the indication information, reduce the reading errors caused by the uncertain location of H-SFN, and improve the efficiency of reading H-SFN.
[0051] In an embodiment, the indication information is used to indicate whether the reference signal carries at least one bit of the H-SFN.
[0052] 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.
[0053] In response to the reference signal not carrying the bit of the H-SFN, the base station may send indication information to indicate that the reference signal does not carry the bit of the H-SFN.
[0054] The UE can determine whether the reference signal carries at least one bit of the H-SFN based on the indication information. If so, the UE can determine at least one bit of the H-SFN from the reference signal. Otherwise, the H-SFN can be determined from other information, such as a system message, based on a direct reservation between the base station and the UE or an agreement in the communication protocol.
[0055] In one embodiment, the indication information is used to indicate the number of bits of the reference signal carrying the H-SFN.
[0056] 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.
[0057] The UE may determine the number of bits of the reference signal carrying the H-SFN based on the indication information, and further determine a corresponding number of bits from the reference signal.
[0058] In an embodiment, the number of bits of the reference signal carrying the H-SFN may implicitly indicate the number of bits of the reference signal carrying the H-SFN.
[0059] In one embodiment, the indication information is used to indicate the number of low-order bits of the H-SFN carried by the reference signal.
[0060] Here, the number of bits of the H-SFN carried by the reference signal indicated by the indication information may be the number of low-order bits of the H-SFN. For example, the indication information may indicate the low-order 1 bit or the low-order 2 bits of the H-SFN.
[0061] In some scenarios, the UE only needs the lowest n bits for synchronization. A superframe occupies 10.24 seconds in the time domain, that is, the lowest bit of the H-SFN can identify plus or minus 10.24 seconds; the lowest two bits can identify plus or minus 20.56 seconds.
[0062] For the case where the UE is configured with the extended discontinuous reception (eDRX) mode, if the duration indicated by the n bits is greater than or equal to the longest eDRX cycle, the UE can only determine the synchronization deviation from the lower n bits of the H-SFN carried by the indication information to complete the synchronization. It is no longer necessary to read the remaining H-SFN bits in SIB1. This reduces the energy consumption generated by reading SIB1, thereby saving power.
[0063] Exemplarily, 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 the synchronization, and n may be selected as 1. When the longest eDRX cycle does not exceed plus or minus 20.48 seconds, the UE may only need to determine the synchronization deviation from the lower two bits of the H-SFN carried by the indication information to complete the synchronization, and n may be selected as 2.
[0064] The UE may determine the number of lower bits of the H-SFN carried by the reference signal based on the indication information, and further determine a corresponding number of lower bits in the reference signal.
[0065] In an embodiment, the sending of the indication information indicating the state of the reference signal carrying the H-SFN includes at least one of the following:
[0066] broadcasting the indication information indicating a state in which the reference signal carries the H-SFN;
[0067] The reference signal unicast indicates that it carries the indication information of the state of the H-SFN.
[0068] The base station may send the indication information to the UE in the form of broadcast and / or unicast.
[0069] For example, the base station may carry the indication information in a broadcast message. The UE may determine, from the broadcast message, that the reference signal carries the indication information of the state of the H-SFN.
[0070] The base station may carry the indication information in existing unicast signaling or add dedicated unicast signaling to send the indication information to the UE. The UE may determine the indication information of the state of the reference signal carrying the H-SFN from the unicast signaling.
[0071] In an embodiment, the sending of indication information indicating a state where a reference signal carries an H-SFN includes:
[0072] Sending a first downlink message carrying both the configuration information of the reference signal and the indication information; wherein the configuration information of the reference signal is at least used to indicate a transmission resource of the reference signal;
[0073] or,
[0074] Send 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.
[0075] The indication information and the configuration information of the reference signal can be carried in the same downlink message and sent to the UE. After receiving the downlink message, the UE can at least determine the transmission resource of the reference signal based on the configuration information of the reference signal, and can determine the state of the reference signal carrying the H-SFN based on the indication information. In this way, the utilization efficiency of the downlink message is improved.
[0076] 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 the number of bits of the reference signal carrying the H-SFN, the UE determines the bits of the H-SFN from the reference information.
[0077] 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 the bit of the H-SFN from other information such as a system message.
[0078] 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 the UE receives a downlink message, it may determine at least the transmission resource of the reference signal based on the configuration information of the reference signal. After the UE receives another downlink message, it may determine the state of the reference signal carrying the H-SFN based on the indication information. In this way, the flexibility of carrying the configuration information and indication information of the reference signal may be improved.
[0079] Here, the downlink message includes but is not limited to: Radio Resource Control (RRC) message.
[0080] In one embodiment, the method further comprises:
[0081] In response to the reference signal carrying at least one bit of the H-SFN, reference signal activation indication information is sent, wherein the reference signal activation indication information is used to indicate the activation state of the reference signal, that is, whether it is activated.
[0082] In response to the base station notifying the UE that the reference signal sent by it carries at least one bit of the H-SFN, the base station also needs to pre-notify the UE of the available state of the reference signal through reference signal activation indication information.
[0083] The reference signal activation indication information indicates that the available state of a reference signal, such as a TRS or a CRS, is represented as the activation state of the resource:
[0084] 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 reasonable, and the network is actually sending the reference signal corresponding to the resource; at this time, for the UE, the reference signal is available; the network expects the UE to use the reference signal resource to receive the reference signal.
[0085] In response to the reference signal activation indication information indicating that the reference signal is in an activated state, the UE may monitor the reference signal, and determine, based on the indication information carried by the reference signal, the state in which the reference signal carries the H-SFN.
[0086] The reference signal activation indication information may indicate that the reference signal is in an inactive state, that the configuration of the reference signal resource is unreasonable, or that the configuration of the resource is reasonable but the network does not actually send the reference signal corresponding to the resource; at this time, for the terminal, the reference signal is unavailable; the network does not expect the terminal to use the reference signal.
[0087] In response to the reference signal activation indication information indicating that the reference signal is in an inactive state, the UE may determine the H-SFN based on other information such as system information.
[0088] In one embodiment, the sending of reference signal activation indication information includes at least one of the following:
[0089] broadcasting a signaling carrying the reference signal activation indication information;
[0090] Sending RRC information carrying the reference signal activation indication information;
[0091] Send downlink control information (DCI, Downlink Control Information) carrying the reference signal activation indication information.
[0092] 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.
[0093] The base station may also carry the reference signal activation indication information through dedicated signaling such as an RRC message or a DCI.
[0094] In an embodiment, the sending of the indication information indicating the state of the reference signal carrying the H-SFN includes at least one of the following:
[0095] broadcasting a signaling carrying the indication information and the reference signal activation indication information;
[0096] Sending the RRC information carrying the indication information and the reference signal activation indication information;
[0097] Send the DCI carrying the indication information and the reference signal activation indication information.
[0098] When the base station notifies the UE of the activation state of the reference signal through broadcast signaling or dedicated signaling, such as RRC message or DCI, it can also carry indication information to notify the UE whether the reference signal sent by it carries at least one bit of the H-SFN.
[0099] In this way, the amount of information carried by broadcast signaling or dedicated signaling, such as RRC messages or DCI, can be increased, thereby improving transmission efficiency.
[0100] In one embodiment, the method further comprises:
[0101] Send the reference signal carrying n bits of the H-SFN, where n is a positive integer greater than or equal to 1 and less than or equal to m, where m is the number of bits of the H-SFN.
[0102] The value range of H-SFN is 0-1023, and 10 bits are needed to represent different H-SFNs.
[0103] In response to the base station dividing 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 at any position of the H-SFN, for example, the n bits of the first part can be n bits of the high position of the H-SFN, or n bits of the low position of the H-SFN. The base station can carry the n bits in the reference 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 SIB1 and sent to the UE.
[0104] The base station may also carry all 10 bits of the H-SFN in a reference signal and send it to the UE.
[0105] Here, the reference signal may be a TRS or a CSI-RS, and the TRS or the CSI-RS may be a shared TRS or CSI-RS, that is, a reference signal that can be used in a connected state, an idle state, or an activated state at the same time.
[0106] In an embodiment, the sending of indication information indicating a state where a reference signal carries an H-SFN includes:
[0107] In response to operating in the eDRX mode, sending the indication information indicating the state in which the reference signal carries the H-SFN.
[0108] In the eDRX mode, the eDRX cycle is long and needs to be synchronized using a super system frame. Thus, in the eDRX mode, the H-SFN needs to be indicated. The base station can indicate the state of the bit of the H-SFN through the indication information.
[0109] In one embodiment, the eDRX mode includes:
[0110] Idle eDRX mode or inactive eDRX mode.
[0111] The eDRX mode can be applied to an idle UE or an inactive UE. In response to the UE being in an idle state or an active state and operating in the eDRX mode, the UE and the base station use a super system frame for synchronization. The base station can indicate the state of the H-SFN bit through indication information.
[0112] like Figure 3 As shown, this exemplary embodiment provides an information transmission method, which can be applied to a user equipment, including:
[0113] Step 301: receiving instruction information;
[0114] Step 302: Determine the state of the reference signal carrying the H-SFN according to the indication information.
[0115] The value range of H-SFN is 0-1023, and 10 bits are needed to represent different H-SFNs.
[0116] The base station may divide the H-SFN into a plurality of parts. For example, the base station may divide the H-SFN into two parts, the first part having n bits and the second part having 10-n bits. The n bits of the first part may be bits at any position of the H-SFN. For example, the n bits of the first part may be n bits of the high position of the H-SFN or n bits of the low position of the H-SFN. 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.
[0117] The base station may carry n bits in a 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 may be carried in a system message and sent to the UE.
[0118] The base station may not divide the H-SFN, but may carry the entire H-SFN in a reference signal and send it to the UE, or may carry the entire H-SFN in a system message and send it to the UE.
[0119] In one embodiment, the reference signal includes: TRS or CSI-RS.
[0120] The base station can carry one or more bits of H-SFN through TRS or CSI-RS. TRS or CRS can be configured closer to the paging opportunity PO time, while the original SSB is far away from the PO position, so the user needs to wake up a long time in advance to synchronize with the SSB. After using TRS or CRS, it can wake up later, so it can save more power.
[0121] In one embodiment, the TRS or CSI-RS is at least used for downlink synchronization of a user equipment UE in an idle state or an inactive state.
[0122] Here, the TRS or CSI-RS may be a TRS or CSI-RS shared by an idle UE or an inactive UE and a connected UE. The idle UE or the inactive UE and the connected UE may monitor the TRS or CSI-RS at the shared TRS or CSI-RS timing.
[0123] Here, the state of the reference signal carrying H-SFN can be at least used for the UE to determine the position of the bit of H-SFN. The state of the reference signal carrying H-SFN includes but is not limited to whether the reference signal carries H-SFN; the position of carrying H-SFN in the reference signal; whether the reference signal carries all bits of H-SFN, etc.
[0124] In this way, the base station can explicitly indicate the state of the reference signal carrying H-SFN through the indication information. On the one hand, the base station can flexibly choose whether to carry the H-SFN state in the reference signal, as well as the bit position carrying H-SFN, and inform the UE through the indication information, thereby improving the flexibility of the reference signal carrying H-SFN. On the other hand, the UE can determine the location of reading H-SFN based on the indication information, reduce the reading errors caused by the uncertain location of H-SFN, and improve the efficiency of reading H-SFN.
[0125] In an embodiment, determining, according to the indication information, a state in which the reference signal carries the H-SFN includes:
[0126] Determine, according to the indication information, whether the reference signal carries at least one bit of the H-SFN.
[0127] 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.
[0128] In response to the reference signal not carrying the bit of the H-SFN, the base station may send indication information to indicate that the reference signal does not carry the bit of the H-SFN.
[0129] The UE can determine whether the reference signal carries at least one bit of the H-SFN based on the indication information. If so, the UE can determine at least one bit of the H-SFN from the reference signal. Otherwise, the H-SFN can be determined from other information, such as a system message, based on a direct reservation between the base station and the UE or an agreement in the communication protocol.
[0130] In an embodiment, determining, according to the indication information, a state in which the reference signal carries the H-SFN includes:
[0131] The number of bits of the reference signal carrying the H-SFN is determined according to the indication information.
[0132] 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.
[0133] The UE may determine the number of bits of the reference signal carrying the H-SFN based on the indication information, and further determine a corresponding number of bits from the reference signal.
[0134] In an embodiment, the number of bits of the reference signal carrying the H-SFN may implicitly indicate the number of bits of the reference signal carrying the H-SFN.
[0135] In an embodiment, determining, according to the indication information, the number of bits of the reference signal carrying the H-SFN includes:
[0136] According to the indication information, the number of low-order bits of the reference signal carrying the H-SFN is determined.
[0137] Here, the number of bits of the H-SFN carried by the reference signal indicated by the indication information may be the number of low-order bits of the H-SFN. For example, the indication information may indicate the low-order 1 bit or the low-order 2 bits of the H-SFN.
[0138] In some scenarios, the UE only needs the lowest n bits for synchronization. A superframe occupies 10.24 seconds in the time domain, that is, the lowest bit of the H-SFN can identify plus or minus 10.24 seconds; the lowest two bits can identify plus or minus 20.56 seconds.
[0139] In the case where the UE is configured with eDRX mode, if the duration indicated by the n bits is greater than or equal to the longest eDRX cycle, the UE can only determine the synchronization deviation from the lower n bits of the H-SFN carried by the indication information to complete the synchronization. It is no longer necessary to read the remaining H-SFN bits in SIB1. This reduces the energy consumption generated by reading SIB1 and saves power.
[0140] Exemplarily, 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 the synchronization, and n may be selected as 1. When the longest eDRX cycle does not exceed plus or minus 20.48 seconds, the UE may only need to determine the synchronization deviation from the lower two bits of the H-SFN carried by the indication information to complete the synchronization, and n may be selected as 2.
[0141] The UE may determine the number of lower bits of the H-SFN carried by the reference signal based on the indication information, and further determine a corresponding number of lower bits in the reference signal.
[0142] In one embodiment, the receiving indication information includes at least one of the following:
[0143] Receiving the broadcasted indication information;
[0144] Receive the unicast indication information.
[0145] The base station may send the indication information to the UE in the form of broadcast and / or unicast.
[0146] For example, the base station may carry the indication information in a broadcast message. The UE may determine, from the broadcast message, that the reference signal carries the indication information of the state of the H-SFN.
[0147] The base station may carry the indication information in existing unicast signaling or add dedicated unicast signaling to send the indication information to the UE. The UE may determine the indication information of the state of the reference signal carrying the H-SFN from the unicast signaling.
[0148] In one embodiment, the receiving indication information includes:
[0149] receiving a first downlink message carrying both the configuration information of the reference signal and the indication information; wherein the configuration information of the reference signal is at least used to indicate a transmission resource of the reference signal;
[0150] or,
[0151] A second downlink message carrying the indication information is received, wherein the second downlink message is different from a third downlink message carrying the configuration information of the reference signal.
[0152] The indication information and the configuration information of the reference signal can be carried in the same downlink message and sent to the UE. After receiving the downlink message, the UE can at least determine the transmission resource of the reference signal based on the configuration information of the reference signal, and can determine the state of the reference signal carrying the H-SFN based on the indication information. In this way, the utilization efficiency of the downlink message is improved.
[0153] 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 the number of bits of the reference signal carrying the H-SFN, the UE determines the bits of the H-SFN from the reference information.
[0154] 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 the bit of the H-SFN from other information such as a system message.
[0155] 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 the UE receives a downlink message, it may determine at least the transmission resource of the reference signal based on the configuration information of the reference signal. After the UE receives another downlink message, it may determine the state of the reference signal carrying the H-SFN based on the indication information. In this way, the flexibility of carrying the configuration information and indication information of the reference signal may be improved.
[0156] Here, the downlink message includes but is not limited to: RRC message.
[0157] In one embodiment, the method further comprises:
[0158] receiving reference signal activation indication information;
[0159] The activation state of the reference signal is determined according to the reference signal activation indication information, that is, whether the reference signal is in an activated state is determined.
[0160] In response to the base station notifying the UE that the reference signal sent by it carries at least one bit of the H-SFN, the base station also needs to pre-notify the UE of the available state of the reference signal through reference signal activation indication information.
[0161] The reference signal activation indication information indicates that the available state of a reference signal, such as a TRS or a CRS, is represented as the activation state of the resource:
[0162] 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 reasonable, and the network is actually sending the reference signal corresponding to the resource; at this time, for the UE, the reference signal is available; the network expects the UE to use the reference signal resource to receive the reference signal.
[0163] In one embodiment, the method further comprises at least one of the following:
[0164] In response to determining that the reference signal is in an activated state, and the indication information indicates that the reference signal carries at least one bit of the H-SFN, determining at least one bit of the H-SFN from at least the reference signal;
[0165] In response to determining that the reference signal is in an activated state, and the indication information indicates that the reference signal does not carry the at least one bit of the H-SFN, determining the at least one bit of the H-SFN from a system message.
[0166] In response to the reference signal activation indication information indicating that the reference signal is in an activated state, the UE may monitor the reference signal, and determine, based on the indication information carried by the reference signal, the state in which the reference signal carries the H-SFN.
[0167] 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, for the terminal, the reference signal is unavailable; the network does not expect the terminal to use the reference signal.
[0168] In one embodiment, the method further comprises:
[0169] In response to determining that the reference signal is in an inactive state, determining a bit position of the H-SFN from a system message.
[0170] In response to the reference signal activation indication information indicating that the reference signal is in an inactive state, the UE may determine the H-SFN based on other information such as system information.
[0171] In one embodiment, the receiving reference signal activation indication information includes at least one of the following:
[0172] receiving a signaling broadcasted by a base station and carrying the reference signal activation indication information;
[0173] Receiving RRC information carrying the reference signal activation indication information;
[0174] Receive DCI carrying the reference signal activation indication information.
[0175] 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.
[0176] The base station may also carry the reference signal activation indication information through dedicated signaling such as an RRC message or a DCI.
[0177] In one embodiment, the receiving indication information includes at least one of the following:
[0178] receiving a signaling broadcast by the base station and carrying the indication information and the reference signal activation indication information;
[0179] receiving the RRC information carrying the indication information and the reference signal activation indication information;
[0180] The DCI carrying the indication information and the reference signal activation indication information is received.
[0181] When the base station notifies the UE of the activation state of the reference signal through broadcast signaling or dedicated signaling, such as RRC message or DCI, it can also carry indication information to notify the UE whether the reference signal sent by it carries at least one bit of the H-SFN.
[0182] In this way, the amount of information carried by broadcast signaling or dedicated signaling, such as RRC messages or DCI, can be increased, thereby improving transmission efficiency.
[0183] In one embodiment, the method further comprises:
[0184] receiving the reference signal;
[0185] Based on the reference signal, n bits of the H-SFN carried by the reference signal are determined, where n is a positive integer greater than or equal to 1 and less than or equal to m, where m is the number of bits of the H-SFN.
[0186] In one embodiment, the method further comprises:
[0187] In response to n being less than m, determining bits other than the n bits of the H-SFN from a system message.
[0188] The value range of H-SFN is 0-1023, and 10 bits are needed to represent different H-SFNs.
[0189] In response to the base station dividing 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 at any position of the H-SFN, for example, the n bits of the first part can be n bits of the high position of the H-SFN, or n bits of the low position of the H-SFN. The base station can carry the n bits in the reference 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 SIB1 and sent to the UE.
[0190] The base station may also carry all 10 bits of the H-SFN in a reference signal and send it to the UE.
[0191] Here, the reference signal may be a TRS or a CSI-RS, and the TRS or the CSI-RS may be a shared TRS or CSI-RS, that is, a reference signal that can be used in a connected state, an idle state, or an activated state at the same time.
[0192] A specific example is provided below in combination with any of the above embodiments:
[0193] 1. The network side such as the base station explicitly notifies the terminal such as the UE of the reference symbols it sends, that is, whether the reference signal carries the H-SFN superframe information.
[0194] a) As an embodiment, the reference symbol is TRS or CSI-RS.
[0195] Furthermore: the reference symbol is a TRS or CSI-RS that assists non-connected users in synchronization.
[0196] 2. The network side explicitly notifies the terminal whether the reference symbols it sends carry H-SFN superframe information, including one of the following parameters:
[0197] a) The presence / absence of H-SFN superframe information.
[0198] b) The number of bits in the reference symbol that carry the H-SFN superframe information.
[0199] As an embodiment, the superframe information carried in the reference symbol is the lower N bits of the H-SFN index.
[0200] Furthermore, the number of N digits can be agreed upon in advance.
[0201] 3. The network side explicitly notifies the terminal whether the reference symbol it sends carries the H-SFN superframe information. The user needs to be notified by broadcast signaling or unicast:
[0202] a) Mode 1: As an embodiment, the indication information may be carried together in the configuration of the reference symbol.
[0203] b) Mode 2: As an embodiment, the indication information may not be sent together with the configuration of the reference symbol, that is, it may be sent separately.
[0204] c) Method 3: See description in 4b).
[0205] 4. If the network 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:
[0206] 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:
[0207] The activated state means that the configuration of the resource is reasonable and the network is actually sending a specific reference signal corresponding to the resource. At this time, the resource is available to the terminal and the network expects the terminal to use it.
[0208] The inactive state means that the resource configuration is unreasonable, or the resource configuration is reasonable but the network does not actually send the specific reference signal corresponding to the resource; at this time, it is unavailable to the terminal; the network does not expect the terminal to use it.
[0209] b) As an embodiment, the network notifies the terminal of the available status of the reference symbol through broadcast signaling or dedicated signaling (RRC message or DCI), and carries the indication information in 3 notifying the terminal whether the reference symbol sent by it carries the H-SFN superframe information.
[0210] 5. When the terminal obtains that the reference symbol is currently in an activated state and learns that the reference symbol carries superframe information, the terminal can obtain the H-SFN information using the information carried in the reference symbol;
[0211] a) Going one step further: the terminal obtains all the complete H-SFN bits; (the advantage of this is that the terminal does not need to obtain superframe information from system messages).
[0212] b) Furthermore, the terminal obtains the lower N H-SFN bits from the reference symbol; the remaining bits need to continue to be obtained from the system message.
[0213] As an embodiment, the system message is a MIB or SIB message. In this way, if the clock drift of the terminal is within the range of N H-SFN bits, it is not necessary to obtain superframe information from the system message.
[0214] 6. When the terminal obtains that the TRS or CRS is currently in a 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).
[0215] 7. Based on 1, the network side displays and notifies the terminal whether the reference symbols it sends carry H-SFN superframe information, which is only used in the scenario where the network supports eDRX.
[0216] a) As an embodiment, the network supports eDRX including idle state eDRX or inactive state eDRX.
