Background

When electronic devices such as a terminal and the like need to occupy the channel for communication in an unlicensed frequency band, the channel can be monitored first, and the channel can be occupied for communication under the condition that the channel is determined to be idle.

In the time when the terminal successfully occupies the channel, the terminal may transmit a physical Uplink Control channel pucch (physical Uplink Control channel), a dynamic grant physical Uplink Shared channel dg (dynamic grant) -PUSCH (physical Uplink Shared channel), a configuration grant physical Uplink Shared channel cg (configured grant) -PUSCH, and the like in an Uplink manner. In order to communicate with the base station, the terminal may share the successfully occupied channel with the base station, and specifically, may send shared information to the base station to notify the base station how to occupy the channel for downlink transmission.

In the related art, in a UE initiated COT (Channel occupancy Time), that is, in a Time when a terminal successfully occupies a Channel as an initiating end, only the terminal is supported to carry shared Information through a CG-UCI (Uplink Control Information) in a CG-PUSCH. However, in some cases, the CG-PUSCH is not transmitted for a long time after the terminal successfully occupies the channel, for example, only the DG-PUSCH is transmitted in the first half of the time when the terminal successfully occupies the channel, which results in that the terminal cannot transmit the shared information to the base station, and downlink transmission of the base station is affected.

Detailed Description

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

Fig. 1 is a schematic flow chart diagram illustrating a sharing indication method according to an embodiment of the present disclosure. The method shown in this embodiment may be applied to a base station, which includes but is not limited to a base station in a communication system such as a 4G base station, a 5G base station, a 6G base station, and the like. The base station may communicate with a terminal as a user equipment, where the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other electronic devices. In an embodiment, the terminal may be a terminal to which the sharing determination method described in any subsequent embodiment is applied.

As shown in fig. 1, the sharing indication method may include the following steps:

in step S101, after a terminal successfully occupies an unlicensed channel as an initiator, the terminal sends shared indication information to the terminal, where the shared indication information is used to indicate, to the terminal, occupation information that the base station is to occupy the unlicensed channel for downlink transmission.

In an embodiment, after the terminal successfully occupies an unlicensed channel (a channel in an unlicensed frequency band) as an initiator, the uplink information may be sent to the base station in the unlicensed channel, and after the base station receives the uplink information sent by the terminal in the unlicensed frequency band, the base station may determine that the terminal successfully occupies the unlicensed channel as the initiator, and then may send the sharing indication information to the terminal.

In an embodiment, the base station may send the shared indication information to the terminal on the authorized channel, or may send the shared indication information to the terminal on the unlicensed channel, for example, the shared indication information may be specifically sent to the terminal on the unlicensed channel successfully occupied by the terminal, or the shared indication information may be sent to the terminal on an unlicensed channel other than the unlicensed channel successfully occupied by the terminal.

The base station may indicate, to the terminal, occupation information that the base station is to occupy the unlicensed channel for downlink transmission, such as a start time at which the unlicensed channel is to be occupied for downlink transmission, a duration for which the unlicensed channel is to be occupied for downlink transmission, and the like, by sending the shared indication information to the terminal, so that the terminal may determine how to receive the downlink information.

According to the embodiment of the disclosure, after the terminal successfully occupies the unlicensed channel as the initiating terminal, the base station may send the shared indication information to the terminal, so as to indicate the terminal with the occupation information that the base station is to occupy the unlicensed channel for downlink transmission. Because the sharing indication information is sent by the base station, the base station can determine how to occupy the unauthorized channel for downlink transmission according to the sharing indication information, so that the terminal is not required to send the sharing information to the base station to inform the base station how to occupy the unauthorized channel for downlink transmission, and even if the CG-PUSCH is not sent in a long time after the terminal successfully occupies the unauthorized channel, the base station can also determine how to occupy the unauthorized channel for downlink transmission.

Optionally, the format of the sharing indication information is log₂And C bits, wherein C is the number of the sharing parameter groups in the sharing indication information.

In one embodiment, the format of the sharing indication information may be log₂C bit, where C is the number of the sharing parameter group in the sharing indication information, the number of bits occupied by the sharing indication information may be determined according to the number of the sharing parameter groups, for example, if there are 2 sharing parameter groups, the sharing indication information occupies log₂When the bit is 0, the base station may be instructed to adopt the first group sharing parameter group to the terminal, and when the bit is 1, the base station may be instructed to adopt the second group sharing parameter group to the terminal. Similarly, for example, if there are 4 sets of sharing parameter sets, the sharing indication information accounts for log₂4-2 bits.

Optionally, the set of sharing parameters includes at least one of the following sharing parameters:

the base station will occupy the duration of the downlink transmission of the unauthorized channel, and the base station will occupy the initial time of the downlink transmission of the unauthorized channel.

In an embodiment, a terminal that occupies an unlicensed channel as an initiator may include two types, one type is Load-Based Equipment (LBE), and the other type is Frame-Based Equipment (FBE), where for the two types of terminals, the shared parameter set may include both a duration that the base station will occupy the unlicensed channel for downlink transmission and a start time that the base station will occupy the unlicensed channel for downlink transmission.

According to the starting time and the duration, the terminal can accurately determine the time domain resource which is to occupy the unauthorized channel by the base station for downlink transmission.

Optionally, the starting time is represented as a first offset with respect to a slot in which the sharing indication information is located.

In an embodiment, the starting time at which the base station to occupy the unlicensed channel for downlink transmission, which is included in the set of shared parameters, may specifically be a first offset, and a unit of the first offset may be set according to needs, for example, may be a slot (slot). After receiving the sharing indication information, the terminal may determine a time slot in which the sharing indication information is located, and then add the first offset to the time slot in which the sharing indication information is located, and an obtained result is used as an initial time at which the base station will occupy the unlicensed channel for downlink transmission.

Optionally, the shared indication information is carried in downlink control information of a physical uplink shared channel for scheduling dynamic grant.

In an embodiment, during the time when the terminal occupies the unlicensed channel, the base station may send Downlink Control Information (DCI) of the DG-PUSCH to the terminal for scheduling the DG-PUSCH, where the format of the Downlink Control channel includes, but is not limited to, DCI format 0-0, DCI format 0-1, and DCI format 0-2.

The downlink control information can carry sharing indication information, so that the sharing indication information does not need to be sent to a terminal independently, and occupation of communication resources is reduced.

Optionally, the starting time is represented by a second offset relative to a time slot in which the dynamically granted physical uplink shared channel is located.

In an embodiment, when the sharing indication information is carried in DCI for scheduling DG-PUSCH, the terminal may determine that the base station schedules DG-PUSCH, the terminal may send DG-PUSCH to the base station according to the DCI scheduled resource, and the base station may send downlink information to the base station according to the received DG-PUSCH, where the starting time of downlink transmission by the base station is after the time when the terminal sends DG-PUSCH to the base station according to the DCI scheduled resource.

In this case, the starting time at which the base station included in the shared parameter group will occupy the unlicensed channel for downlink transmission may specifically be a second offset, and a unit of the second offset may be set according to needs, and may be, for example, a time slot. After receiving the sharing indication information, the terminal may determine a time slot in which the DG-PUSCH scheduled by the DCI is located, and then add the second offset to the time slot, where the obtained result is used as an initial time at which the base station will occupy an unlicensed channel for downlink transmission.

In general, the time slot in which the DG-PUSCH scheduled by the DCI is located is closer to the starting time at which the base station will occupy the unlicensed channel for downlink transmission than the time slot in which the shared indication information is located, that is, the second offset is generally smaller than the first offset in the above embodiment, so that bits occupied by indicating the starting time by the second offset may be relatively less than bits occupied by indicating the starting time by the first offset.

Optionally, in response to the terminal being a load-based device, the set of sharing parameters further includes sharing parameters:

channel Access Priority Class (CAPC for short).

In an embodiment, when the terminal is a load-based device, the terminal may further indicate a channel access priority to the terminal through a shared parameter value, so that the terminal knows a relevant parameter of the base station access channel. And when the terminal is a frame-based device, it may not be necessary to indicate a channel access priority to the terminal.

Optionally, the shared indication information is used to indicate that the base station starts to occupy the unlicensed channel for downlink transmission for a first time period after the time slot in which the shared indication information is located, and a duration of occupying the unlicensed channel for downlink transmission is less than or equal to a relevant time period of a subcarrier interval of the unlicensed channel;

or

The shared indication information is used for indicating the base station not to occupy the unauthorized channel for downlink transmission.

In an embodiment, the format of the shared indication information may be a preset number of bits, and the base station may indicate, to the terminal, occupation information that the base station is to occupy the unlicensed channel for downlink transmission through the shared indication information of the preset number of bits, for example, an initial time at which the unlicensed channel is to be occupied for downlink transmission, a maximum transmission duration at which the unlicensed channel is to be occupied for downlink transmission, and the like.

In an embodiment, the shared indication information of the preset number of bits may indicate two situations, for example, including that the base station is to occupy the unlicensed channel for downlink transmission, and does not occupy the unlicensed channel for downlink transmission.

For example, when the preset number of bits is equal to the first value, the base station may be instructed not to occupy the unlicensed channel for downlink transmission. For example, the preset number is 1, the first value is 0, that is, the format of the sharing indication is 1 bit, and when the bit is 0, the terminal may determine that the base station does not occupy the unlicensed channel for downlink transmission, and may not need to monitor the unlicensed channel for a period of time after receiving the sharing indication information.

For example, when the preset number of bits is equal to the second value, the base station may be instructed to start to occupy the unlicensed channel for downlink transmission for a first time period after the time slot in which the shared indication information is located, and a duration for occupying the unlicensed channel for downlink transmission is less than or equal to a relevant time period of a subcarrier interval of the unlicensed channel.

Correspondingly, for example, the preset number is 1, the first value is 1, that is, the format of the sharing indication is 1 bit, and when the bit is 1, the terminal may determine that the base station starts to occupy the unlicensed channel for downlink transmission for a first time period after the time slot in which the sharing indication information is located, and the duration for occupying the unlicensed channel for downlink transmission is less than or equal to the relevant time period of the subcarrier interval of the unlicensed channel.

The unit of the first duration may be set as required, for example, a time slot, a symbol, and the like. The specific first time duration may be preconfigured to the terminal by the base station, for example, by RRC (Radio Resource Control) layer signaling.

After receiving the sharing indication information, the terminal may determine a time slot in which the sharing indication information is located, then add the first duration to the time slot in which the sharing indication information is located, obtain a result as an initial time at which the base station will occupy an unlicensed channel for downlink transmission, and then monitor the unlicensed channel from the initial time so as to receive downlink information sent by the base station.

If the SubCarrier Spacing (also referred to as SubCarrier bandwidth) of the unlicensed channel can be determined, and then the correlation duration of the SubCarrier Spacing (the correlation duration of different SubCarrier spacings can be predetermined by a communication protocol) is determined, the unlicensed channel can be monitored in a time domain range smaller than or equal to the correlation duration.

Fig. 2 is a schematic flow chart diagram illustrating another sharing indication method according to an embodiment of the present disclosure. As shown in fig. 2, the sending of the sharing indication information to the terminal includes:

in step S1011, in response to the physical uplink shared channel that does not receive the configuration grant sent by the terminal within the second duration, sending sharing indication information to the terminal.

In an embodiment, the base station may determine that the terminal successfully occupies the unlicensed channel as an initiator and then start timing to determine a duration of a CG-PUSCH transmitted by the terminal, and may transmit the sharing indication information to the terminal if the duration is greater than or equal to the second duration.

Under the condition that the terminal can carry the shared information through the CG-UCI in the CG-PUSCH, when the base station receives the CG-PUSCH, the shared information carried by the CG-UCI can be obtained from the CG-UCI, and then the shared information determines which channel is occupied for downlink transmission.

However, if the base station does not receive the CG-PUSCH transmitted by the terminal within the second duration, the base station does not know how to occupy the unlicensed channel for a long time after the terminal successfully occupies the unlicensed channel, so that it is difficult to transmit downlink information to the terminal in the unlicensed channel.

In this case, the base station may determine how to occupy the authorized channel by itself, for example, may determine according to a historical communication condition with the terminal, and further generate the shared indication information, and then send the shared indication information to the terminal, so as to ensure that after the terminal successfully occupies the unauthorized channel, the base station can determine how to occupy the unauthorized channel in time, so as to send downlink information to the terminal.

Fig. 3 is a schematic flow chart diagram illustrating yet another sharing indication method according to an embodiment of the present disclosure. As shown in fig. 3, the method further comprises:

in step S102, in response to receiving the physical uplink shared channel of the configuration grant sent by the terminal within the third duration, according to the uplink control information of the configuration grant in the physical uplink shared channel of the configuration grant, the occupancy information that the base station is to occupy the unlicensed channel for downlink transmission is determined.

In an embodiment, the base station may determine that the terminal successfully occupies the unlicensed channel as an initiator and then starts timing to determine a duration of not receiving the CG-PUSCH transmitted by the terminal, and if the duration is less than or equal to a third duration, that is, the CG-PUSCH transmitted by the terminal is received within the third duration, that is, the sharing indication information may be transmitted to the terminal.

Under the condition that the terminal can carry the shared information through the CG-UCI in the CG-PUSCH, the base station can obtain the shared information carried by the CG-UCI when receiving the CG-PUSCH, and further determine which channel is occupied for downlink transmission according to the shared information.

After the base station receives the CG-PUSCH sent by the terminal in the third time length, namely the terminal successfully occupies the unauthorized channel, the base station can know how to occupy the unauthorized channel in a shorter time, so that the downlink information is sent to the terminal in the unauthorized channel.

In this case, the base station may determine, according to the shared information carried by the CG-UCI, occupation information that the base station is to occupy the unlicensed channel for downlink transmission, without sending the shared indication information to the terminal.

It should be noted that the time length related parameters such as the first time length, the second time length, the third time length, and the like in all embodiments of the present disclosure may be set as needed, and the time length related parameters may be equal or unequal.

Fig. 4 is a schematic flow chart diagram illustrating a sharing determination method according to an embodiment of the present disclosure. The method shown in this embodiment may be applied to a terminal, where the terminal includes, but is not limited to, an electronic device such as a mobile phone, a tablet computer, a wearable device, a sensor, and an internet of things device. The terminal may communicate with a base station as a user equipment, and the base station includes but is not limited to a 4G base station, a 5G base station, and a 6G base station. In an embodiment, the base station may be a base station to which the sharing indication method described in any of the above embodiments is applied.

As shown in fig. 4, the sharing determination method may include the steps of:

in step S201, an originating node occupies an unlicensed channel;

in step S202, receiving sharing indication information sent by the base station;

in step S203, the occupation information that the base station is to occupy the unlicensed channel for downlink transmission is determined according to the shared indication information.

In an embodiment, after the terminal successfully occupies an unlicensed channel (a channel in an unlicensed frequency band) as an initiator, the terminal may send uplink information to the base station on the unlicensed channel, and after the base station receives the uplink information sent by the terminal in the unlicensed frequency band, the base station may determine that the terminal successfully occupies the unlicensed channel as the initiator, and then may send shared indication information to the terminal, and the terminal may receive the shared indication information sent by the base station.

In an embodiment, the terminal may receive, in the authorized channel, the shared indication information sent by the base station, or may receive, in the unlicensed channel, the shared indication information sent by the base station, for example, the shared indication information sent by the base station may be specifically received in the unlicensed channel successfully occupied by the terminal, or the shared indication information sent by the base station may be received in an unlicensed channel other than the unlicensed channel successfully occupied by the terminal.

According to the received shared indication information, the terminal may determine occupation information that the base station is to occupy the unlicensed channel for downlink transmission, for example, a starting time at which the unlicensed channel is to be occupied for downlink transmission, a duration time at which the unlicensed channel is to be occupied for downlink transmission, and the like, so that the terminal may determine how to downlink information.

According to the embodiment of the disclosure, after the terminal serving as an initiator successfully occupies an unlicensed channel, the terminal may receive shared indication information sent by a base station to determine occupation information that the base station is to occupy the unlicensed channel for downlink transmission. Because the sharing indication information is sent by the base station, the base station can determine how to occupy the unauthorized channel for downlink transmission according to the sharing indication information, so that the terminal is not required to send the sharing information to the base station to inform the base station how to occupy the unauthorized channel for downlink transmission, and even if the CG-PUSCH is not sent in a long time after the terminal successfully occupies the unauthorized channel, the base station can also determine how to occupy the unauthorized channel for downlink transmission.

Optionally, the format of the sharing indication information is log₂And C bits, wherein C is the number of the sharing parameter groups in the sharing indication information, and C is greater than or equal to 1.

In one embodiment, the format of the sharing indication information may be log₂C bit, where C is the number of the sharing parameter group in the sharing indication information, the number of bits occupied by the sharing indication information may be determined according to the number of the sharing parameter groups, for example, if there are 2 sharing parameter groups, the sharing indication information occupies log₂When the bit is 0, the terminal may be instructed to adopt the first set of shared parameter group by the base station, and when the bit is 1, the terminal may be instructed to adopt the base station by the base stationThe second set shares the parameter set. Similarly, for example, if there are 4 sets of sharing parameter sets, the sharing indication information accounts for log₂4-2 bits.

As shown in fig. 5, the determining, according to the shared indication information, that the base station is to occupy the unlicensed channel for downlink transmission includes:

in step S20311, the start time is determined according to the time slot where the sharing indication information is located and the first offset in the sharing parameter set.

Fig. 7 is a schematic flow chart diagram illustrating yet another sharing determination method according to an embodiment of the present disclosure. As shown in fig. 7, the receiving the sharing indication information sent by the base station includes:

in step S2021, the shared indication information is obtained from the downlink control information of the physical uplink shared channel for scheduling dynamic grant.

In one embodiment, the base station may send downlink control information of the DG-PUSCH to the terminal for scheduling the DG-PUSCH during a time when the terminal occupies the unlicensed channel, where a format of the downlink control channel includes, but is not limited to, DCI format 0-0, DCI format 0-1, and DCI format 0-2.

The downlink control information can carry sharing indication information, and the terminal can acquire the sharing indication information from the downlink control information, so that the base station is not required to independently send the sharing indication information to the terminal, and the occupation of communication resources is reduced.

or

In step S2034, it is determined that the base station does not occupy the unlicensed channel for downlink transmission according to the shared indication information.

The unit of the first duration may be set as required, for example, a time slot, a symbol, and the like. The specific first time duration may be preconfigured to the terminal by the base station, for example, by RRC layer signaling.

If the subcarrier spacing of the unlicensed channel can be determined, and then the correlation duration of the subcarrier spacing is determined (the correlation duration of different subcarrier spacings can be predetermined by a communication protocol), the unlicensed channel can be monitored in a time domain range smaller than or equal to the correlation duration.
