Unlicensed spectrum (also known as shared spectrum or unlicensed spectrum) is the spectrum allocated by countries and regions that can be used for radio equipment communication. This spectrum can be used according to the regulatory requirements set by the region on the spectrum, without applying for a dedicated spectrum license from the government.

In order to enable various communication systems that use unlicensed spectrum for wireless communication to coexist amicably on this spectrum, some countries or regions have stipulated regulatory requirements that must be met when using unlicensed spectrum. For example, a communication device follows the principle of "Listen Before Talk (LBT)", that is, before a communication device transmits a signal on an unlicensed spectrum channel, it needs to perform channel listening first, and only when the channel listening result is The communication device can send signals only when the channel is idle; if the channel detection result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot send signals. In order to ensure fairness, in a transmission, the duration of signal transmission by a communication device using an unlicensed spectrum channel cannot exceed the maximum channel occupancy time (Maximum Channel Occupancy Time, MCOT).

For another example, in order to avoid causing subband interference to signals transmitted on unlicensed spectrum channels, and to improve the detection accuracy of communication devices when detecting unlicensed spectrum channels, signals transmitted on unlicensed spectrum channels need to be Occupy at least a certain percentage of the channel bandwidth. For example, the 5GHz frequency band is 80% of the channel bandwidth occupied by the signal, and the 60GHz frequency band is 70% of the channel bandwidth occupied by the signal. Taking 20MHz as an example, if the target of 80% of the channel bandwidth occupied by the signal is to be satisfied, the bandwidth occupied by the signal should be at least 16MHz.

For another example, in order to avoid the power of the signal transmitted on the channel of the unlicensed spectrum being too large and affecting the transmission of other important signals on the channel, such as radar signals, the regulations stipulate that the communication equipment uses the channel of the unlicensed spectrum for signal transmission. maximum power and maximum power spectral density at .

In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, which all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

For better understanding of the embodiments of the present application, the CG timer mechanism and the related background of the NRU are first described below.

NRU related background:

NRU includes the following working scenarios:

Scenario A: In a carrier aggregation scenario, the primary cell (Primary Cell, PCell) corresponds to the licensed spectrum, and the secondary cell (Secondary Cell, SCell) corresponds to the unlicensed spectrum.

Scenario B: Dual-connection working scenario, PCell corresponds to LTE licensed spectrum, and Primary Secondary Cell (PScell) corresponds to unlicensed spectrum.

Scenario C: Independent working scenario, an independent cell works on unlicensed spectrum.

Scenario D: NR single-cell scenario, the uplink (Uplink, UL) works on the licensed spectrum, and the downlink (Downlink, DL) works on the unlicensed spectrum;

In the NRU scenario, in order to better serve periodic services, the concept of pre-configured resources is introduced, such as Semi-Persistent Scheduling (SPS) and Configured Grant (CG) resources. The maximum number of Hybrid Automatic Repeat reQuest (HARQ) processes supported by the terminal is 16. For each CG resource, the network configures a limited number of HARQ process numbers for it, and the HARQ process of the CG resource at time t0 The number is the same as the HARQ process number of the CG resource at time t1. For example, when the media access control (Media Access Control, MAC) packet generates MAC protocol data unit (Protocol Data Unit, PDU) 1 at time t0, the MAC PDU1 is stored in the HARQ process A. After time t1, due to the HARQ process The same, MAC PDU1 will be overwritten (flush), even if the MAC PDU has not been transmitted correctly at this time. Therefore, a mechanism for configuring a grant timer (configuredGrantTimer) per (per)HARQ process is introduced. Before the configuredGrantTimer expires, the MAC PDU stored in the HARQ process cannot be flushed. After the configuredGrantTimer times out, the terminal device determines that the network device will not adjust and retransmit, and can use the resources corresponding to the HARQ process for data transmission.

Among them, the configured Grant Timer is maintained by each HARQ process, that is, the configured Grant Timer only restricts the use of the CG resources of its corresponding HARQ process, and does not restrict the use of the CG resources of other HARQ processes.

A configuration grant retransmission timer (cg-RetransmissionTimer) is introduced to trigger automatic retransmission on CG resources. Specifically, before the cg-RetransmissionTimer timer expires and the configuredGrantTimer does not expire, if no acknowledgement (Acknowledgement, ACK) is received, automatic retransmission is triggered.

Example 3-1:

As an example, if the first HARQ process is in a not pending state (not pending), the terminal device may use the first CG resource to perform new data transmission. The fact that the first HARQ process is not suspended indicates that data on the first HARQ process has been transmitted, and in this case, the first CG resource can be used to perform new data transmission.

As another example, if the first HARQ process is in a pending state (pending), the terminal device may use the first CG resource to retransmit data. The suspension of the first HARQ process can be understood as the data on the first HARQ process has been packaged but not yet transmitted, or the data on the first HARQ process has been acquired but not yet transmitted. Data retransmission is performed using the first CG resource.

As another example, if there is untransmitted data in the first HARQ process, the terminal device uses the first CG resource to perform new transmission or retransmission of data. The existence of untransmitted data in the first HARQ process indicates that there is still data to be transmitted in the first HARQ process. In this case, the untransmitted data may be transmitted in a new transmission or retransmission manner.

As another example, if there is no untransmitted data in the first HARQ process, the terminal device uses the first CG resource to perform new data transmission.

As another example, if there is untransmitted data on the first HARQ process and the first HARQ process is in an unsuspended state, the terminal device uses the first CG resource to perform new data transmission.

As another example, if the first HARQ process is in a suspended state and the last resource corresponding to the first HARQ process is a CG resource, the terminal device uses the first CG resource to retransmit data.

As another example, if the network device indicates that the DFI content is NACK for the first HARQ process, the terminal device uses the first CG resource to retransmit data.

As another example, if the network device indicates that the DFI content is ACK for the first HARQ process, the terminal device uses the first CG resource to perform new data transmission.

As another example, if the network device indicates that the DFI content is NACK for the first HARQ process, and the HARQ process is not pending, the terminal device uses the first CG resource to retransmit data.

As another example, if the network device indicates that the DFI content is ACK for the first HARQ process, and the HARQ process is not pending, the terminal device uses the first CG resource to perform new data transmission.

To sum up, the terminal device can use the first CG resource to retransmit data when at least one of the following conditions is satisfied: the first HARQ process is in a suspended state;

S320, the network device sends the configuration information of the first CG resource to the terminal device.

Correspondingly, the terminal device receives the configuration information of the first CG resource sent by the network device.

Optionally, in some embodiments, the first CG resource may be a resource on an unlicensed spectrum, that is, the embodiment of the present application may be applied to a scenario in which data transmission is performed using a resource on an unlicensed spectrum, for example Several NRU scenarios described above.

Optionally, in some embodiments, the configuration information of the first CG resource shown may further include information of the first CG resource, such as the starting position of the resource, the size and period of the resource, and the like. That is, when configuring the CG resource, the network device may configure the CG retransmission timer corresponding to the CG resource at the same time.

In this embodiment, the configuration information of the first CG resource may be generated based on a first constraint, and the first constraint may be used to indicate that the CG timer and the CG retransmission timer corresponding to the same CG resource need to be They are configured together, or in other words, both are configured or neither are configured. In other words, when the CG retransmission timer is configured, the CG timer needs to be configured at the same time.

Optionally, the first constraint condition may be set in the configuration rule of the CG timer, or set in the configuration rule of the CG retransmission timer. Exemplarily, it may be defined in the domain description in the RRC of the cg-RetransmissionTimer, or may be defined in the domain description in the RRC of the configuredGrantTimer.

Alternatively, This field is always configured for operation with shared spectrum. channel access together with cg-RetransmissionTimer".

Among them, "This field is always configured for operation with shared spectrum channel access together with cg-RetransmissionTimer or harq-ProcID-Offset" means: the configuredGrantTimer field is usually used together with cg-RetransmissionTimer or harq-ProcID-Offset for shared spectrum channel access operation.

Among them, "This field is always configured for operation with shared spectrum channel access together with cg-RetransmissionTimer" means: The configuredGrantTimer field is usually used together with cg-RetransmissionTimer for the operation of shared spectrum channel access.

The harq-ProcID-Offset represents the HARQ process offset, which is used to determine which HARQ processes of the CG resource are.

As a concrete example:

The field description for configuredGrantTimer can be:

"Indicates the initial value of the configured grant timer(see TS 38.321[3]) in multiples of periodicity. When cg-RetransmissonTimer is configured, if HARQ processes are shared among different configured grants on the same BWP, configuredGrantTimer is set to the same value for all of configurations on this BWP.This field is always configured for operation with shared spectrum channel access together with cg-RetransmissionTimer".

When cg-RetransmissonTimer is configured, if HARQ processes are shared among different configured grants on the same BWP, configuredGrantTimer is set to the same value for all of configurations on this BWP" means: to indicate the initial value of the configured grant timer (see TS 38.321[3]). The configuredGrantTimer timer length is a multiple of the period. With cg-RetransmissonTimer configured, if HARQ processes are shared between different configuration grants on the same BWP, then configuredGrantTimer is set to the same value for all configurations on that BWP.

Wherein, the "This field is always configured for operation with shared spectrum channel access together with cg-RetransmissionTimer" indicates that the configuredGrantTimer field is usually used together with the cg-RetransmissionTimer field for the operation of shared spectrum channel access.

The domain description for cg-RetransmissionTimer can be:

"Indicates the initial value of the configured retransmission timer(see TS 38.321[3]) in multiples of periodicity. The value of cg-RetransmissionTimer is always less than the value of configuredGrantTimer. This field is always configured for operation with shared spectrum channel access together with harq-ProcID-Offset.This field is not configured for operation in licensed spectrum or simultaneously with harq-ProcID-Offset2.If this field is configured,configuredGrantTimer is always configured together”.

Among them, "Indicates the initial value of the configured retransmission timer(see TS 38.321[3]) in multiples of periodicity. The value of cg-RetransmissionTimer is always less than the value of configuredGrantTimer. This field is always configured for operation with shared spectrum channel access together with harq-ProcID-Offset.This field is not configured for operation in licensed spectrum or simultaneously with harq-ProcID-Offset2" means: indicates the initial value of the retransmission timer (see TS 38.321[3]). The length of the cg-RetransmissionTimer timer is a multiple of the period. The value of cg-RetransmissionTimer is always less than the value of configuredGrantTimer. This field is always configured with harq-ProcID-Offset for shared spectrum channel access operation. This field is not configured in licensed spectrum or at the same time as harq-ProcID-Offset2.

Wherein, the "This field is always configured for operation with shared spectrum channel access together with cg-RetransmissionTimer" indicates that the cg-RetransmissionTimer field is usually used together with the configuredGrantTimer field for the operation of shared spectrum channel access.

For example, after the terminal device sends the first data using the first CG resource, it can start or restart the configured Grant Timer of the HARQ process. When the terminal device starts the configured Grant Timer corresponding to the HARQ process, it simultaneously starts the cg-RetransmissionTimer corresponding to the HARQ process, wherein the duration of the cg-RetransmissionTimer is shorter than the configured Grant Timer. Before the cg-RetransmissionTimer times out and the configured Grant Timer does not time out, if no ACK is received, the terminal device triggers data retransmission using the first CG resource.
