The terminal device may also be referred to as a User Equipment (UE), a terminal, etc.

As described in the background art, in the prior art, the resource efficiency of the system is seriously reduced by adopting the repeated transmission manner, so as to limit the system capacity of the IOT NTN.

Specifically, the inventor discovers that the unlicensed data transmission mode can save the resource overhead of the control signaling, further improve the capacity of the IOT NTN system, and can consider that the unlicensed data transmission mode is introduced in the IOT NTN. And how to implement activation/deactivation of the pre-configured resources is a problem to be solved.

In the technical scheme of the application, the activation/deactivation of the preconfigured data transmission resource can be realized through the first information, so that the scheduling-free uplink and downlink transmission is realized, the overhead of control signaling can be reduced, and the system capacity of the narrowband Internet of things network is greatly improved.

Specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1, the method provided by the application specifically includes the following steps:

Step 101: the network device sends the first information to the terminal device. Wherein the first information indicates activation or deactivation of at least one set of pre-configured data transmission resource parameter sets. Accordingly, the terminal device receives the first information.

It will be appreciated that in a specific implementation, the communication method may be implemented in a software program running on a processor integrated within a chip or a chip module. The method may also be implemented by combining software with hardware, and the application is not limited.

In this embodiment, the preconfigured data transmission resource may be preconfigured for the terminal device by the network device. The number of the pre-configured data transmission resource parameter sets may be one or more, and the terminal device may determine the corresponding periodic pre-configured data transmission resource through the one pre-configured data transmission resource parameter set. Each set of preconfigured data transmission resources may be a periodic uplink resource or a periodic downlink resource.

Specifically, for uplink pre-configured resources, two transmission types may be included: uplink configuration grant type (Configured GRANT TYPE 1) and uplink configuration grant type2 (Configured GRANT TYPE).

More specifically, for uplink configuration grant type 1, the network device may be configured (e.g., field IE ConfiguredGrantConfig) through radio resource control (Radio Resource Control, RRC). After receiving the configuration of the uplink configuration authorization type 1, the terminal equipment can use the uplink resource of the uplink configuration authorization type 1 to carry out uplink data transmission, namely, the uplink configuration authorization type 1 resource can be used after network configuration, and activation/deactivation is not required through downlink control information.

For uplink configuration grant type 2, the network device may configure (e.g., field IE ConfiguredGrantConfig) the relevant parameters through radio resource control (Radio Resource Control, RRC). And then, activating and deactivating the resources of the uplink configuration authorization type 2 through the DCI indication, namely, after the network transmits relevant parameter configuration through RRC for the uplink configuration authorization type 2 resources, the network needs to activate/deactivate through downlink control information, and only the uplink configuration authorization type 2 resources in an activated state can be used for uplink data transmission.

Specifically, for the downlink pre-configured resource, it may be a Semi-persistent scheduling (Semi-PERSISTENT SCHEDULING, SPS) resource. The network device specifies radio resources used by the terminal device using SPS resources (i.e., SPS C-RNTI scrambled PDCCHs) with which the terminal device periodically transceives data. Specifically, after receiving a specific DCI (i.e., DCI in an SPS C-RNTI scrambled PDCCH) or an RRC configuration message, the terminal device starts to periodically perform PDSCH reception until such persistent scheduling is stopped.

The network device activates or deactivates the parameter set of the preconfigured data transmission resource through the first information, so that the terminal device can utilize the activated preconfigured data transmission resource to perform uplink and downlink data transmission. The embodiment of the application enables the IOT NTN to support the uplink and downlink transmission without scheduling, which can reduce the cost of control signaling and greatly improve the system capacity of the IOT NTN.

In one non-limiting embodiment, the first information is carried on a first indication field of the downlink control information (Downlink Control Information, DCI).

In the embodiment of the application, the DCI is designed to bear the first information, so that the network can activate and deactivate the preconfigured uplink or downlink data transmission resources, and the utilization efficiency of the resources is further improved.

Further, the first information may be carried in different indication fields in the DCI. This will be described in detail with reference to specific examples.

In embodiment 1, the first indication field includes a subcarrier indication field, the first information is used to activate the parameter set of the preconfigured data transmission resource, the first information is carried on N bits in the subcarrier indication (Subcarrier indication) field, and the remaining bits in the subcarrier indication field (i.e., bits other than the N bits in the subcarrier indication field) indicate a corresponding target subcarrier allocation scheme on the frequency domain of at least one preconfigured data transmission resource, where N is a positive integer greater than or equal to 1.

The preconfigured data transmission resource in this embodiment is a preconfigured uplink data transmission resource. The first information indicates activation of at least one set of pre-configured uplink data transmission resource parameter sets. And the terminal equipment determines an activated pre-configured uplink data transmission resource parameter set according to the value of the N bits. In addition, the terminal device can also determine the target subcarrier where the preconfigured data transmission resource is located according to the remaining bits of the subcarrier indication field, so that the terminal device can perform data transmission on the preconfigured data transmission resource activated on the target subcarrier.

Further, the pre-configured data transmission resources may be referred to as configuration scheduling (Configured Scheduled) resources.

In this embodiment, the format (format) of the DCI is N0. The DCI of format N0 is used for PUSCH scheduling and pre-configuring activation and deactivation operations of uplink data transmission resources. DCI format N0 includes a subcarrier indication field, a resource allocation indication field, a scheduling delay indication field, a redundancy version (Redundancy version) indication field, a number of repeated transmissions indication field, a hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) process number (process number) indication field, a modulation and coding scheme (Modulation and coding scheme) indication field, and the like.

Specifically, the N bits of the subcarrier indication field may be high N bits, low N bits, or N bits of a fixed position, which is not limited in the present application.

Specifically, each bit of the N bits corresponds to one or more sets of preconfigured uplink data transmission resource parameter sets, and when a certain bit of the N bits takes a value of 1, the one or more sets of preconfigured uplink data transmission resource parameter sets corresponding to the bit are indicated to be in an active state. Or when the value of one bit of the N bits is 0, one or more sets of pre-configured uplink data transmission resource parameter sets corresponding to the bit are activated. The remaining bits of the subcarrier indication field indicate that the target subcarrier allocation scheme is applied to the corresponding active pre-configured data transmission resources.

Specifically, the value of N is 4, and each bit of the 4 bits of the subcarrier indication field corresponds to a set of preconfigured uplink data transmission resource parameter sets. As shown in table 1, bit 0 corresponds to the preconfigured uplink data transmission resource parameter set 0, bit 1 corresponds to the preconfigured uplink data transmission resource parameter set 1, bit 2 corresponds to the preconfigured uplink data transmission resource parameter set 2, and bit 3 corresponds to the preconfigured uplink data transmission resource parameter set 3.

3	Preconfigured uplink data transmission resource parameter set 3

Referring to fig. 2 together, an interaction flow chart of the communication method provided in embodiment 1 of the present application specifically includes the following steps:

In step 201, the network device sends a first higher layer signaling to the terminal device. Accordingly, the terminal device receives the first higher layer signaling. The first higher layer signaling is used to indicate a plurality of candidate subcarrier allocation schemes, each candidate subcarrier allocation scheme including a position of a subcarrier and a number of subcarriers, and at least a portion of the plurality of candidate subcarrier allocation schemes of the target subcarrier allocation scheme.

That is, the network device indicates a plurality of candidate subcarrier allocation schemes to the terminal device through the first higher layer signaling, and then indicates an activated preconfigured data transmission resource parameter set and a target subcarrier allocation scheme applied on a frequency domain of the activated preconfigured data transmission resource through the DCI.

Specifically, the number of remaining bits of the subcarrier indication field is 2. As shown in table 2, when the value of the remaining bits is 00, the target subcarriers allocated on the frequency domain of the preconfigured data transmission resource are subcarriers indicated by subcarrier index 0 and subcarrier index 4; similarly, when the value of the remaining bit is 01, the target subcarriers allocated on the frequency domain of the preconfigured data transmission resource are subcarriers indicated by subcarrier index 2 and subcarrier index 6; when the value of the residual bit is 10, the target subcarriers allocated on the frequency domain of the pre-configured data transmission resource are subcarriers indicated by subcarrier indexes 4 and 8; and when the value of the residual bit is 11, the target subcarriers allocated on the frequency domain of the preconfigured data transmission resource are subcarriers indicated by a subcarrier index 6 and a subcarrier index 12.

Step 202, the network device sends first information to the terminal device. Accordingly, the terminal device receives the first information.

In an alternative embodiment, the plurality of candidate subcarrier allocation schemes may also be defined by a communication standard protocol, as the application is not limited in this regard.

In this embodiment, the terminal device determines the deactivated preconfigured uplink data transmission resource parameter set according to the value of the N bits.

In this embodiment, each bit of the N bits corresponds to one or more sets of preconfigured uplink data transmission resource parameter sets, and when a certain bit of the N bits takes a value of 1, the one or more sets of preconfigured uplink data transmission resource parameter sets corresponding to the bit are in a deactivated state. Or when the value of one bit of the N bits is 0, one or more sets of pre-configured uplink data transmission resource parameter sets corresponding to the bit are in a deactivated state.

Wherein, the preconfigured uplink data transmission resource corresponding to the preconfigured uplink data transmission resource parameter set in the deactivation state is in the deactivation state.

In a specific embodiment, values of other indication fields in DCI of format N0 are shown in table 4.

In embodiment 3, the first indication field includes a retransmission number indication field, the first information is used to activate the parameter set of the preconfigured data transmission resource, the first information is carried on N bits of the retransmission number indication field, and the remaining bits of the retransmission number indication field (i.e. bits other than the N bits in the retransmission number indication field) indicate the target retransmission number corresponding to the at least one preconfigured data transmission resource. In this embodiment, the target number of repeated transmissions corresponding to at least one preconfigured data transmission resource indicates the number of repeated transmissions applied to the at least one preconfigured data transmission resource.

In a specific embodiment, the preconfigured data transmission resource may be an uplink resource, i.e. a preconfigured uplink data transmission resource. In this case, the format of DCI is N0. The first information indicates activation or deactivation of a pre-configured uplink data transmission resource parameter set. And the terminal equipment determines an activated or deactivated pre-configured uplink data transmission resource parameter set according to the value of the N bits.

In another embodiment, the preconfigured data transmission resource may be a downlink resource, i.e. a preconfigured downlink data transmission resource. In this case, the format of DCI is N1. Wherein DCI of format N1 is used for scheduling of each PDSCH codeword per Transmission time interval (Transmission TIME INTERVAL, TTI) in one cell, a random access procedure initiated by PDCCH order, informing SC-multicast control channel (Multicast Control Channel, MCCH) of change, and operation on preconfigured downlink resources. The first information indicates activation or deactivation of a pre-configured downlink data transmission resource parameter set. And the terminal equipment determines an activated or deactivated pre-configured downlink data transmission resource parameter set according to the value of the N bits.

Further, the pre-configured downlink data transmission resource may be a Semi-persistent scheduling (Semi-PERSISTENT SCHEDULING, SPS) resource.

Specifically, the N bits of the retransmission number indication field may be high N bits, low N bits, or N bits of a fixed position, which is not limited in the present application.

Specifically, each bit of the N bits corresponds to one or more sets of pre-configured downlink data transmission resource parameter sets, and when the value of a certain bit of the N bits is 1, the one or more sets of pre-configured downlink data transmission resource parameter sets corresponding to the bit are indicated to be in an active state. Correspondingly, when the value of a bit on the N bits is 0, one or more sets of pre-configured downlink data transmission resource parameter sets corresponding to the bit are shown as the repeated transmission times corresponding to the activated pre-configured data transmission resource in the deactivated state repeated transmission times indication field.

Referring to fig. 3, an interaction flow chart of the communication method provided in embodiment 3 of the present application specifically includes the following steps:

The second higher layer signaling is used to indicate a number of candidate retransmissions. The target number of retransmissions is at least a portion of the plurality of candidate number of retransmissions.

That is, the network device indicates a plurality of candidate repeated transmission times to the terminal device through the second higher layer signaling, and then activates the pre-configured data transmission resource parameter set and the target repeated transmission times applied to the frequency domain of the pre-configured data transmission resource through the DCI indication.

Specifically, the number of repeated transmission times indicates that the number of remaining bits of the field is 2. As shown in table 5, when the value of the remaining bits is 00, the number of repeated transmissions of the preconfigured data transmission resource application is 2; similarly, when the value of the remaining bit is 01, the number of repeated transmission times of the pre-configured data transmission resource application is 4; when the value of the residual bit is 10, the repeated transmission times of the pre-configured data transmission resource application are 6; and when the value of the remaining bit is 11, the repeated transmission times of the pre-configured data transmission resource application are 8.
