This disclosure relates to the field of communication technologies, and in particular, to a data transmission method, an apparatus, and a storage medium.
In some communication systems, such as a 5th generation (5G) communication system, a network device may configure a measurement gap (GAP) for a terminal device, and the terminal device measures a reference signal of a neighbor cell in the measurement GAP without transmitting data with a serving cell.
However, measurement GAPs configured by the network device are usually dense, causing high resource occupation of the measurement GAPs. Therefore, how to reduce the resource occupation of the measurement GAPs is an urgent problem to be resolved.
Embodiments of this disclosure provide a data transmission method, an apparatus, and a storage medium, to reduce resource occupation of a measurement GAP.
According to a first aspect, an embodiment of this disclosure provides a data transmission method, including: A first terminal device determines N second GAP occasions based on M first GAP occasions, where the M first GAP occasions include the N second GAP occasions, the M first GAP occasions are periodic time domain positions that are of a first GAP and that are configured by a first network device, M is greater than N, and both M and N are positive integers; and the first terminal device stops, on the N second GAP occasions, receiving a first signal sent by the first network device.
According to the data transmission method provided in the first aspect, some GAP occasions are determined from a plurality of GAP occasions configured by the first network device, to prevent all the configured GAP occasions of a GAP from taking effect on the first terminal device, which results in the GAP occupying a large quantity of resources, and therefore to reduce resource occupation of the GAP.
In a possible implementation, the method further includes: The first terminal device receives configuration information sent by the first network device, where the configuration information is used to configure the periodic time domain positions of the first GAP.
According to the data transmission method provided in this implementation, the periodic time domain positions of the first GAP are configured for the first terminal device, to determine the N second GAP occasions from the periodic time domain positions of the first GAP.
In a possible implementation, the configuration information includes at least one of a periodicity, an offset value, and a time domain length of the first GAP.
According to the data transmission method provided in this implementation, the first GAP is flexibly configured.
In a possible implementation, the N second GAP occasions are determined from the M first GAP occasions based on an identifier of the first terminal device or an identifier of a terminal device group to which the first terminal device belongs.

The data transmission method provided in this implementation helps the N second GAP occasions that can be used by the first terminal device to be selected from the M first GAP occasions, to prevent the GAP from occupying a large quantity of communication resources of the first terminal device.

In a possible implementation, W is less than or equal to a quotient of the periodicity T of the first GAP and the measurement periodicity L.
According to the data transmission method provided in this implementation, a smaller value of W than the quotient of the periodicity T of the first GAP and the measurement periodicity L indicates denser second GAP occasions, so that the second GAP occasions can better cover a measurement time of the reference signal, and accuracy of radio resource management (RRM) measurement of the first terminal device is higher.

The network device may provide a service for the terminal device in a form in which a central unit (CU) and a distributed unit (DU) are separated. A specific technology and a specific device form that are used by the network device are not limited in embodiments of this disclosure.

A spectrum resource used between the network device and the terminal device is not limited in embodiments of this disclosure.
For ease of understanding of embodiments of this disclosure, a communication system applicable to embodiments of this disclosure is first described in detail with reference to
It should be understood that a communication system 101 may be a subsystem of the communication system 100 or a communication system independent of the communication system 100. A communication system 102 may be a subsystem of the communication system 100 or a communication system independent of the communication system 100.
Regardless of whether the terminal device in the communication system shown in
A signal received by the terminal device by using the main circuit may be referred to as being transmitted on the primary link. The primary link represents a connection relationship between the terminal device and the network device, and is a logical concept rather than a physical entity. It may be understood that the primary link is merely a name for differentiation, and a specific name of the primary link does not limit the protection scope of this disclosure.
A WUR module is configured to: receive a wake-up signal (WUS, also referred to as a low-power wake-up signal (LP-WUS)) sent by the network device, and demodulate wake-up indication information based on an information bit carried in the WUS, to wake up a main receiver or a main receiving module that is disabled (or that is in a sleep state) in the terminal device. In this embodiment, that the terminal device receives the wake-up signal by using the WUR module is also referred to as operating on a WUR link, or is also referred to as that the WUR module is in an operating state. The wake-up signal may be used to wake up at least one terminal device or at least one group of terminal devices. In an example, the wake-up signal includes wake-up information. The wake-up information indicates information related to waking up the terminal device. For example, the wake-up information is information related to paging. For example, the wake-up information may be used by the terminal device to determine whether to perform a paging receiving procedure, or may be used by the terminal device to determine whether to initiate random access. When paging information carried in the wake-up signal indicates a paged terminal device, the wake-up information may include information (such as a UE ID) about one or more terminal devices that need to be woken up. In this case, a woken-up terminal device may directly initiate random access after the MR is started. When the paging information carried in the wake-up signal indicates a paged terminal device group (UE group), the wake-up information may include a group identifier of the terminal device group. In this case, a woken-up terminal device in the group may continue to receive paging information on a PO after the MR is started, to determine whether the terminal device is paged. In some scenarios, the wake-up signal may further carry scheduling information. In this case, the terminal device is in a connected state, and the wake-up signal indicates whether the terminal device needs to start an MR to receive the scheduling information (for example, whether a physical downlink control channel (PDCCH) needs to be monitored).
In an NR system, the terminal device may implement cell reselection through radio resource management (RRM) measurement. The RRM measurement may include serving cell measurement and neighbor cell measurement. The neighbor cell measurement includes intra-frequency measurement, inter-frequency measurement, and inter-system (inter-RAT) measurement. It should be understood that the intra-frequency measurement means that a serving cell of a terminal device and a to-be-measured neighbor cell are on a same carrier frequency. The inter-frequency measurement means that a serving cell of a terminal device and a to-be-measured neighbor cell are not on a same carrier frequency. The inter-system measurement means that a serving cell of a terminal device and a to-be-measured neighbor cell are not in a same communication system or do not use a same communication standard. For example, the serving cell is in a 5G system, and the neighbor cell is in a 4G communication system or uses a 4G communication standard.
A carrier frequency of the serving cell may also be referred to as a working frequency of the serving cell, and a carrier frequency of the neighbor cell may also be referred to as a working frequency of the neighbor cell. In an RRM measurement scenario, when the terminal device receives a reference signal at the working frequency of the serving cell to implement the serving cell measurement, the working frequency of the serving cell may also be referred to as a measurement frequency of the serving cell. Similarly, when the terminal device receives a reference signal at the working frequency of the neighbor cell to implement the neighbor cell measurement, the working frequency of the neighbor cell may also be referred to as a measurement frequency of the neighbor cell.
Based on the example of the low-power wake-up scenario shown in
In Scenario 1, the terminal device may perform serving cell measurement and neighbor cell measurement by using the MR. When the terminal device performs inter-frequency measurement, the terminal device switches a measurement frequency of the MR to the measurement frequency of the neighbor cell.
In Scenario 2, the terminal device may perform serving cell measurement and neighbor cell measurement in the following several possible manners:
In Manner 1 and Manner 2, the terminal device switches the current communication apparatus from the WUR to the MR. The following is described with reference to a diagram of an architecture of a communication apparatus shown in
Modules/Components and connection relationships between the modules/components shown in
It should be understood that, when the terminal device performs RRM measurement by using the MR, a received reference signal may be a synchronization signal block (SSB). When the terminal device performs RRM measurement by using the WUR, a received reference signal may include a low-power measurement reference signal, where the low-power measurement reference signal may be periodically sent. In a case, the received reference signal may also include a low-power synchronization signal (LP-SS), where the low-power consumption synchronization signal may be periodically sent.
It should be further understood that, when the terminal device performs inter-frequency measurement by using the MR in Scenario 1 or performs inter-frequency measurement by using the WUR in Manner 3 of Scenario 2, the measurement frequency needs to be switched to the measurement frequency of the neighbor cell. In Manner 1 and Manner 3 of Scenario 2, the terminal device switches the current communication apparatus from the WUR to the MR, to perform serving cell measurement or neighbor cell measurement by using the MR. Regardless of whether the terminal device performs measurement frequency switching or communication apparatus switching, communication of the terminal device on an original measurement frequency (or working frequency) or by using an original communication apparatus is interrupted. Therefore, it is considered that a measurement GAP is configured, so that the terminal device can perform inter-frequency measurement or inter-system measurement in the measurement GAP.
To enable configured measurement GAPs to meet measurement requirements of different terminal devices, GAPs configured by the network device are usually dense, causing high resource occupation of the measurement GAPs.
For the problem of high resource occupation of the measurement GAPs, in an embodiment of this disclosure, a terminal device determines some measurement GAP occasions from measurement GAP occasions of the configured measurement GAPs, and does not receive, on the determined some measurement GAP occasions, a first signal sent by a network device. The first signal may be a signal transmitted on a frequency before frequency switching, or may be a signal that can be received by a communication apparatus before communication apparatus switching. This prevents the configured GAPs from occupying a large quantity of resources.
It should be noted that, for ease of understanding, in this embodiment of this disclosure, only an example in which a terminal device performs inter-frequency measurement or inter-system measurement in a measurement GAP is used for description. However, that a configured GAP is a measurement GAP and that the terminal device performs measurement in the GAP are not limited in this disclosure. The GAP may be understood as a periodic time domain position at which the terminal device does not receive the first signal.
That the terminal device determines some GAP occasions from a plurality of GAP occasions of the configured GAP may also be expressed as selecting some GAP occasions from the plurality of GAP occasions of the configured GAP. In this disclosure, meanings expressed by “determining” and “selecting” used alternately are consistent.
It should be further understood that, when a GAP occasion is used by the terminal device (or a GAP occasion corresponds to the terminal device), the network device cannot send the first signal to the terminal device on the GAP occasion. Therefore, there are less available resources of the network device for sending the first signal to the terminal device. Less available resources of the network device for sending the first signal may be understood as higher GAP overheads, that is, higher resource occupation of the GAP.
In this embodiment of this disclosure, the terminal device determines some GAP occasions, that is, GAP occasions used by the terminal device, from the plurality of GAP occasions of the configured GAP. However, on an unselected GAP occasion in the plurality of GAP occasions of the configured GAP, the network device may still send the first signal to the terminal device. In other words, the GAP occasion that is not selected by the terminal device does not occupy available resources for communication between the terminal device and the network device.
The following describes a communication method provided in embodiments of this disclosure with reference to the accompanying drawings.
It should be understood that, for ease of understanding and description, the following mainly describes the method provided in embodiments of this disclosure by using interaction between a first terminal device and a first network device as an example. For example, the first terminal device may be a terminal device 121 or 122 in
In some embodiments, interaction between the first terminal device and a second network device is used as an example to further describe the method provided in embodiments of this disclosure. For example, the first terminal device may be the terminal device 121 or 122 in
Optionally, the first terminal device may be used in the low-power wake-up scenario shown in
However, it should be understood that this shall not constitute any limitation on an execution body of the method provided in this disclosure. Any device that can perform, by using a program that runs code of the method provided in embodiments of this disclosure, the method provided in embodiments of this disclosure may be used as the execution body of the method provided in embodiments of this disclosure. For example, the first terminal device shown in the following embodiments may also be replaced with a component in the first terminal device, for example, a chip, a chip system, or another functional module that can invoke a program and execute the program. The network device shown in the following embodiments may also be replaced with a component in the network device, for example, a chip, a chip system, or another functional module that can invoke a program and execute the program.
It should be noted that the time domain position of the first GAP in each GAP periodicity is one GAP occasion. The time domain positions of the first GAP in GAP periodicities include the M first GAP occasions. The M first GAP occasions may be all or some of the configured time domain positions of the first GAP. This is not limited in this disclosure.
It should be further understood that the M first GAP occasions cover GAP occasions (for example, the N second GAP occasions) required by the first terminal device, and a quantity of the M first GAP occasions is greater than a quantity of the GAP occasions required by the first terminal device. For example, the M first GAP occasions may be dense GAP occasions that are configured by the first network device to meet measurement requirements of a plurality of terminal devices. The plurality of terminal devices may be all or some of terminal devices in a serving cell of the first network device, and the first terminal device is any one of the plurality of terminal devices.
The first network device may send the configuration information to all of the plurality of terminal devices including the first terminal device, to configure the first GAP for each terminal device. Each terminal device may determine respective second GAP occasion based on the periodic time domain position that is of the first GAP and that is configured by the first network device. Correspondingly, the first network device may determine the second GAP occasion of each terminal device based on the configured periodic time domain position of the first GAP.
Optionally, the configuration information may include at least one of a periodicity, an offset value, and a time domain length of the first GAP. Refer to
The N second GAP occasions may be GAP occasions that are in the M first GAP occasions and that have a mapping relationship with the first terminal device. For example, the mapping relationship may be a mapping relationship between an identifier (for example, UE_ID) of the first terminal device and the first GAP. For another example, the mapping relationship may be a mapping relationship between an identifier (for example, group_ID) of a terminal device group to which the first terminal device belongs and the first GAP.
For example, the M first GAP occasions may be divided into W groups, where W is a positive integer. The N second GAP occasions may be some or all of first GAP occasions in a group of the W groups. With reference to
The mapping relationship between the first terminal device and the first GAP may be represented by using the following formula:
i is an identifier (for example, an index (index)) of the first GAP, and mod represents a modulo (or referred to as a modulo) operation.
In a first embodiment, D in the foregoing formula may be the identifier (for example, UE_ID) of the first terminal device. For example, the M first GAP occasions are divided into four groups, and a terminal device whose identifier is 1 has a mapping relationship with a 1st first GAP occasion, a 5th first GAP occasion, a 9th first GAP occasion, and the like. In other words, when the identifier of the first terminal device is 1, the N second GAP occasions corresponding to the first terminal device include the 1st first GAP occasion, the 5th first GAP occasion, the 9th first GAP occasion, and the like.
In a second embodiment, D in the foregoing formula may be the identifier (for example, group_ID) of the terminal device group to which the first terminal device belongs. For example, the M first GAP occasions are divided into four groups, and a group whose identifier is 1 has a mapping relationship with a 1st first GAP occasion, a 5th first GAP occasion, a 9th first GAP occasion, and the like. In other words, when the identifier of the group to which the first terminal device belongs is 1, the N second GAP occasions corresponding to the first terminal device include the 1st first GAP occasion, the 5th first GAP occasion, the 9th first GAP occasion, and the like.
In the second embodiment, the identifier (for example, group_ID) of the terminal device group to which the first terminal device belongs may be configured by the network device, or may be obtained through calculation based on the identifier (for example, UE_ID) of the first terminal device.
Further, to enable the N second GAP occasions to better meet the measurement requirement, the M first GAP occasions may be divided into W groups based on a measurement periodicity L. The measurement periodicity L may be a measurement periodicity that meets a measurement periodicity requirement. The measurement periodicity requirement may be predefined (for example, defined in a protocol). For example, the measurement periodicity L may be equal to the measurement periodicity requirement. Alternatively, when the measurement periodicity L meets the measurement periodicity requirement, the measurement periodicity may be determined with reference to a sending periodicity of a reference signal of the network device and a requirement of a communication service on communication quality.
In an implementation of dividing the M first GAP occasions into W groups based on the measurement periodicity L, W may be equal to a quotient of a periodicity T of the first GAP and the measurement periodicity L. For example, with reference to
In another implementation, W may be less than the quotient of the periodicity T of the first GAP and the measurement periodicity L. In this case, the first terminal device may determine denser second GAP occasions. For example, the periodicity of the first GAP is 3.2 s, the measurement periodicity requirement is 12.8 s, W is equal to 2, and there is one second GAP occasion in every two first GAP occasions. When density of the second GAP occasions is increased, impact of a small quantity of second GAP occasions on accuracy of the RRM measurement of the first terminal device can be avoided.
By adjusting a degree to which W is less than the quotient of the periodicity T of the first GAP and the measurement periodicity L, GAP overheads can be flexibly controlled.
In S220, an implementation in which the first network device determines the N second GAP occasions is similar to the implementation in which the first terminal device determines the N second GAP occasions. A sequence of performing S210 and S220 by the first network device is not limited in this embodiment of this disclosure. For example, the first network device may determine the N second GAP occasions before sending the configuration information, or the first network device may determine the N second GAP occasions after sending the configuration information.
That the first terminal device stops receiving, on the N second GAP occasions, the first signal sent by the first network device may be expressed as that the first terminal device does not receive, on the N second GAP occasions, the first signal sent by the first network device, or may be expressed as that the first terminal device deactivates, on the N second GAP occasions, receiving of the first signal sent by the first network device.
In some examples of S230, on the N second GAP occasions, the first terminal device does not expect to receive the first signal sent by the first network device, or the first terminal device does not expect to monitor the first signal sent by the first network device, or the first terminal device does not need to receive the first signal sent by the first network device, or the first terminal device does not need to monitor the first signal sent by the first network device.
Correspondingly, that the first network device stops, on the N second GAP occasions, sending the first signal to the first terminal device may be expressed as that the first network device does not send the first signal to the first terminal device on the N second GAP occasions, or may be expressed as that the first network device deactivates, on the N second GAP occasions, sending of the first signal.
Therefore, with reference to the method 200 shown in
In some embodiments, the configuration information may be carried in a broadcast message sent by the first network device, so that a terminal device in an idle state or an inactive state receives the configuration information, to resolve a problem in which the terminal device currently in the idle state or the inactive state cannot determine a measurement GAP. Certainly, that the first terminal device is in the idle state or the inactive state when receiving the broadcast message is not limited in this disclosure. For example, the first terminal device may be in a connected state.
Optionally, the broadcast message includes radio resource control (RRC) signaling. The RRC signaling includes the configuration information of the first GAP, and the RRC signaling may be sent by using a system information block (SIB).
It should be noted that, when the terminal device performs measurement by using an MR, a measurement frequency of a serving cell may be a frequency domain position/frequency range of an SSB of the serving cell, and a measurement frequency of a neighbor cell may be a frequency domain position/frequency range of an SSB of the neighbor cell. When the terminal device performs measurement by using a WUR, the measurement frequency of the serving cell may be a frequency domain position/frequency range at which the first signal of the serving cell is sent, or may be referred to as a working frequency for receiving the first signal in the serving cell, that is, the first frequency range. The measurement frequency of the neighbor cell may be a frequency domain position at which the second signal of the neighbor cell is sent, or may be referred to as a working frequency for receiving the second signal in the neighbor cell, that is, the second frequency range.
With reference to the low-power wake-up scenario shown in
Certainly, this is not limited in this disclosure. Alternatively, the first signal may be any signal received by the MR on the measurement frequency (or the working frequency) of the serving cell. For example, an MR of the first terminal device is in an on state, and the first terminal device may receive, outside of the N second GAP occasions by using the MR in the first frequency range, the first signal sent by the first network device. In this case, on the N second GAP occasions, the first terminal device may fail to receive the first signal due to measurement frequency switching.
That the first terminal device and the first network device stop transmitting the first signal in the first frequency range includes: The first terminal device stops receiving the first signal in the first frequency range, and the first network device stops sending the first signal in the first frequency range. As described above, stopping receiving may also be expressed as not receiving or deactivating receiving, and stopping sending may also be expressed as not sending or deactivating sending.
As described above, the first terminal device may perform neighbor cell measurement, for example, inter-frequency measurement or inter-system measurement, on the N second GAP occasions. The second frequency range may be a frequency range in which the measurement frequency of the neighbor cell is located. In this way, the first network device and the first terminal device align time domain positions occupied for the neighbor cell measurement, so that communication stability is improved.
In an implementation of S232, the first terminal device may receive the second signal in the second frequency range by using a first communication apparatus. The first communication apparatus may be a WUR. When the MR of the first terminal device is in an off state, the first terminal device may receive the signal of the first network device and/or the second network device by using the WUR. For example, the first terminal device receives the first signal outside of the N second GAP occasions by using the WUR in the first frequency range in which the frequency of the serving cell is located, switches the WUR to the measurement frequency of the neighbor cell on the N second GAP occasions, and further receives the second signal in the second frequency range in which the measurement frequency of the neighbor cell is located. Optionally, the second signal may include a measurement reference signal of the neighbor cell.
In another implementation of S232, the first terminal device may receive the second signal in the second frequency range by using a second communication apparatus. For example, the second communication apparatus may be an MR. The first terminal device may receive the first signal outside of the N second GAP occasions by using the first communication apparatus (for example, the WUR) in the first frequency range in which the frequency of the serving cell is located, switch the communication apparatus from the WUR to the MR on the N second GAP occasions, and receive, by using the MR, the second signal in the second frequency range in which the measurement frequency of the neighbor cell is located. Optionally, the second signal may include a measurement reference signal of the serving cell or the measurement reference signal of the neighbor cell. It should be understood that, when the second signal includes the measurement reference signal of the serving cell, the first communication apparatus may be a communication apparatus that does not support RRM measurement or does not have an RRM measurement capability. When the second signal includes the measurement reference signal of the neighbor cell, the first communication apparatus may be a communication apparatus that does not support neighbor cell measurement or does not have a neighbor cell measurement capability.
Therefore, in the embodiment shown in
In some embodiments, the time domain length of the first GAP is greater than or equal to duration for measuring a reference signal of the neighbor cell, so that the first terminal device can completely receive, on each second GAP occasion, a reference signal sent in one reference signal periodicity of the neighbor cell.
Further, when the first terminal device receives the second signal in the second frequency range, frequency switching needs to be performed, for example, the measurement frequency of the serving cell needs to be switched to the measurement frequency of the neighbor cell. In this case, the time domain length of the first GAP should further include duration for measurement frequency switching, for example, a time for a radio frequency front-end switch to switch between different frequencies. In this case, the time domain length of the first GAP may be several milliseconds or tens of milliseconds. Alternatively, when the first terminal device receives the second signal in the second frequency range, the first communication apparatus needs to be switched to the second communication apparatus. In this case, the time domain length of the first GAP should further include duration for switching from the first communication apparatus to the second communication apparatus. In this case, the time domain length of the first GAP may be several milliseconds (ms) or tens of milliseconds. The first communication apparatus is configured to receive the first signal in the first frequency range, and the second communication apparatus is configured to receive the second signal in the second frequency range.
In some embodiments, when the second communication apparatus performs communication apparatus switching (for example, switching from the first communication apparatus to the second communication apparatus), the second communication apparatus is not started, and the time domain length of the first GAP should further include duration for starting the second communication apparatus. In this case, the time domain length of the first GAP may be several milliseconds or several seconds. Certainly, if the second communication apparatus has been started before the second communication apparatus performs communication apparatus switching (for example, switching from the first communication apparatus to the first communication apparatus), duration of the first GAP does not include the duration for starting the second communication apparatus.
For example, the first communication apparatus is a WUR and the second communication apparatus is an MR. The MR may be started under wakeup of the WUR. As described above, the WUR may wake up the MR after receiving an LP-WUS. In addition, the WUR may periodically wake up the MR. This is not limited in this disclosure.
Considering that the duration of the first GAP can cover at least one of the duration for measurement frequency switching, the duration for communication apparatus switching, and the duration for starting the second communication apparatus, in different measurement scenarios, the first terminal device can completely receive, on each second GAP occasion, the reference signal sent in one reference signal periodicity of the neighbor cell.
