Optionally, a Device to Device (D2D) communication may be performed between the terminal devices 120.

Alternatively, the 5G system or the 5G network may also be referred to as a New Radio (NR) system or an NR network.

Fig. 1 exemplarily shows one network device and two terminal devices, and optionally, the communication system 100 may include a plurality of network devices and may include other numbers of terminal devices within the coverage of each network device, which is not limited in this embodiment of the present application.

Optionally, the communication system 100 may further include other network entities such as a network controller, a mobility management entity, and the like, which is not limited in this embodiment.

It should be understood that a device having a communication function in a network/system in the embodiments of the present application may be referred to as a communication device. Taking the communication system 100 shown in fig. 1 as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function, and the network device 110 and the terminal device 120 may be the specific devices described above and are not described herein again; the communication device may also include other devices in the communication system 100, such as other network entities, for example, a network controller, a mobility management entity, and the like, which is not limited in this embodiment.

It should be understood that the research and standardization of the 5G technology enables wireless broadband mobile communication to have higher peak rate, larger transmission bandwidth and lower transmission delay. For example, the working bandwidth of 5G terminal equipment is in the order of 100MHz to hundreds MHz, the data transmission rate is in Gbps, and the transmission delay is reduced to the ms level.

However, some implementation and specific use problems are also caused for the terminal device, for example, the power consumption of the terminal device is increased compared with the conventional wireless communication system due to the broadband terminal radio frequency and the extremely fast baseband processing. This may affect the standby time and the usage time of the 5G terminal device and even the battery life of the terminal.

In view of the above, the present application proposes a flexible configuration mechanism, in which a network device can send an indication signaling to a terminal device, by which the target configuration information for time domain resource allocation is flexibly indicated to the terminal device, therefore, the terminal device can determine the time domain resource of the transmission data channel according to the target configuration information, for example, in the case that the time delay requirement of the service to be transmitted on the data channel is low, the time domain resources for transmitting the data channel indicated by the target configuration information may be spaced apart from the time domain resources of the control channel scheduling the data channel by a larger time interval, thus, the terminal device can reduce the demodulation speed of the control channel and the coding speed of the data channel, that is, the terminal device can receive data or transmit data at a lower chip operation speed, thereby reducing the power consumption of the terminal device.

Fig. 2 is a schematic flow chart of a method for wireless communication according to an embodiment of the present application, where the method 200 may be performed by a terminal device, as shown in fig. 2, where the method 200 includes the following steps:

s210, a terminal device receives a first signaling, wherein the first signaling indicates target configuration information in a plurality of configuration information for time domain resource allocation;

s220, the terminal equipment determines the time domain resource used by the transmission data channel according to the target configuration information.

Optionally, in this embodiment of the present application, the plurality of configuration information for time domain resource allocation may be preconfigured, specifically, the plurality of configuration information may be agreed by a protocol, and further, the plurality of configuration information agreed by the protocol may be preset on the terminal device. Alternatively, the configuration information may also be configured by the network device, and optionally, the network device may configure the configuration information for the terminal device through static or semi-static signaling, for example, the network device may configure the configuration information for the terminal device through Radio Resource Control (RRC) signaling. Alternatively, some configuration information in the plurality of configuration information may be configured by the network device, and other configuration information may be preconfigured, which is not limited in this embodiment of the present application.

In this embodiment of the present application, the terminal device may receive a first signaling sent by the network device, where the first signaling may be used to indicate target configuration information in the multiple pieces of configuration information, and further, the terminal device may determine, according to the target configuration information indicated by the first signaling, a time domain resource used for transmitting a data channel, for example, information such as a time interval of the time domain resource used for transmitting the data channel relative to a time domain resource of a control channel that schedules the data channel, a scheduling manner of the data channel, and a start position and a length of the time domain resource.

Optionally, in this embodiment of the application, the first signaling may be dynamic signaling such as Media Access Control (MAC) Control Element (CE) signaling or Physical Downlink Control Channel (PDCCH).

Specifically, the indication information may be carried in the first signaling, where the indication information is used to indicate the target configuration information configured by the network device, and optionally, the indication information may be at least one bit, specifically, the length of the indication information may be determined according to the number of the plurality of configuration information, and it is assumed that the plurality of configuration information are two configuration information, in this case, the indication information may be 1 bit, or, if the plurality of configuration information are three configuration information, in this case, the indication information is 2 bits, and further, when the indication information is set to be different values, the indication information is used to indicate different configuration information.

Optionally, in this embodiment of the present application, the data Channel may be a Physical Downlink Shared Channel (PDSCH) or a Physical Uplink Shared Channel (PUSCH) or other channels for transmitting data or traffic.

It should be noted that the configuration information for time domain resource allocation (timesdomainresource allocation) may be used to determine the time domain resource of the transmission data channel, and optionally, each of the configuration information includes at least one of the following parameters:

the time domain resource of the data channel is relative to the time interval of the control channel for scheduling the data channel, or called timing difference, if the data channel is PDSCH, the positioning difference may be the timing difference between PDCCH and PDSCH, i.e. K0, or if the data channel is PUSCH, the positioning difference may be the timing difference between PDCCH and PUSCH, i.e. K2;

a scheduling manner of the data channel, or a mapping type (mappingType) of the data channel, for example, scheduling based on slot (slot) or scheduling based on non-slot (non-slot);

a starting time domain position and length (startsymbol and length) of a time domain resource of the data channel, which may optionally be used to indicate a starting symbol position and a number of consecutively occupied symbols of the data channel.

Of course, the configuration information for time domain resource allocation in the embodiment of the present application may also include other related parameters, which is not specifically limited in the embodiment of the present application.

It should be understood that the timing difference between the PDCCH and the PDSCH is an offset of a time unit in which the PDCCH and the PDSCH are located, and taking the time unit as a time slot as an example, the timing difference between the PDCCH and the PDSCH may be an offset of a time slot in which the PDCCH and the PDSCH are located. If the timing difference is zero, that is, K0 is 0, the PDSCH is scheduled in the same time slot, that is, the PDCCH for scheduling data and the scheduled PDSCH are in the same time slot; or if the timing difference is greater than zero, the PDSCH is scheduled across time slots, that is, the PDCCH for scheduling data and the scheduled PDSCH are in different time slots. The same is true for the meaning of the positioning difference K2, which is not described in detail here.

It can be understood that the simultaneous slot scheduling generally requires the terminal device to increase the demodulation speed of the PDCCH and the coding speed of the PUSCH, which causes the terminal device to receive data or transmit data at a higher chip clock running speed, resulting in greater power consumption of the terminal device. For cross-slot scheduling, the terminal device may reduce the demodulation speed of the PDCCH and the coding speed of the PUSCH, so that the terminal device may receive data or transmit data at a lower chip clock operation speed, which is beneficial to reducing power consumption of the terminal device.

Therefore, in this embodiment of the present application, a plurality of configuration information may be configured to a terminal device, where each configuration information corresponds to a set of parameters, and assuming that the plurality of configuration information includes a first configuration information and a second configuration information, the first configuration information is configured to support simultaneous slot scheduling, that is, the minimum K0/K2 is equal to 0, and the second configuration information is configured to support only cross-slot scheduling, that is, the minimum K0/K2 is greater than 0, in other words, the first configuration information may be applicable to a service with a higher scheduling latency requirement, and the second configuration information may be applicable to a service with a lower scheduling latency requirement, then in different scenarios, the network device may indicate different configuration information to the terminal device through the first signaling. Specifically, the network device may determine which configuration information is configured for the terminal device according to the delay requirement of the service to be scheduled, for example, in a case that the delay requirement of the service to be scheduled is low, the first signaling may indicate the second configuration information, so that the terminal device may reduce the demodulation speed of the PDCCH and the coding speed of the PUSCH, that is, the terminal device may receive data or transmit data at a low chip operation speed, so as to reduce the power consumption of the terminal device.

It should be understood that, in the embodiment of the present application, the plurality of configuration information may further include more configuration information, for example, third configuration information, each of which may correspond to an application scenario or a latency requirement, which is not limited in the embodiment of the present application, and the first configuration information and the second configuration information are taken as an example for description below.

Alternatively, in some embodiments, the first configuration information and the second configuration information may be independent configuration information (denoted as case 1), or the second configuration information may be configuration information based on the first configuration information (denoted as case 2), that is, the configuration information for time domain resource allocation of the data channel indicated by the second configuration information needs to be determined according to the first configuration information.

For example, the second configuration information may be offset information with respect to the first configuration information, so that the terminal device may determine, according to the first configuration information and the offset information, configuration information for time domain resource allocation corresponding to the second configuration information.

Hereinafter, the time domain resource allocation of the PDSCH will be described as an example with reference to specific tables shown in tables 1 to 4. The parameters shown in tables 1 to 4 are merely examples for explaining the problem, and do not limit the number, types, and values of the parameters at all.

For case 1, the first configuration information and the second configuration information may correspond to the configuration information shown in table 1 and table 2, respectively, and as can be seen from table 1 and table 2, the timing difference (i.e., K0) in table 1 is smaller than the timing difference in table 2, that is, table 1 is more suitable for the service with higher transmission delay requirement, and table 2 is more suitable for the service with lower transmission delay requirement. Therefore, under the condition that the time delay requirement of the service to be scheduled is not high, the network equipment can configure the configuration information in the step 2 for the terminal equipment, and the power consumption of the terminal equipment is favorably reduced; or, in a case that the delay requirement of the service to be scheduled is high, the network device may configure the configuration information in table 1, for example, configuration 1 or configuration 2 in table 1, to the terminal device, so as to ensure that the service to be scheduled is transmitted in time.

It should be understood that the first configuration information and the second configuration information may correspond to independent tables, or may also be a table corresponding to the first configuration information and the second configuration information may be merged into a table, for example, configuration 1 to configuration 4 in table 2 may be merged into table 1, and the index values are modified to configuration 5 to configuration 8, and then the network device may indicate the configured configuration information to the terminal device through the index values of configuration 1 to configuration 8, for this example, 3 bits may be used to indicate configuration 1 to configuration 8, and the 3 bits take different values to indicate configuration 1 to configuration 8.

Optionally, in this embodiment of the present application, the multiple pieces of configuration information may also be merged together, and a specific configuration item in each piece of configuration information after merging is indicated by a different index value.

For case 2, the first configuration information may correspond to the configuration information shown in table 3, the second configuration information may be offset information, and optionally, the offset information may be a single offset, and the single offset may be applied to each configuration item or a part of the configuration items in table 3, for example, the single offset may be applicable to configuration 1 to configuration 4 in table 3, or only to configuration 1 and configuration 2 in table 3; or the offset information may be a set of offsets, each corresponding to one configuration item in table 3, and the specific corresponding manner is not particularly limited.

Alternatively, taking the second configuration information indicating a single offset (K0_ offset) as an example, assuming that the K0_ offset is 2 and the single offset is applicable to each configuration item in table 3, the configuration information for time domain resource allocation corresponding to the second configuration information may be determined according to the first configuration information and the offset, as shown in table 4.

TABLE 3

TABLE 4

In a specific implementation, under a condition that a delay requirement of a service to be scheduled is not high, a network device may configure second configuration information to a terminal device, and further, the terminal device may obtain the configuration information in table 4 according to offset information indicated by the first configuration information and the second configuration information, and further may determine a time domain resource for transmitting the PDSCH according to the configuration information in table 4; under the condition that the delay requirement of the service to be scheduled is high, the network device may configure the configuration information in table 3, for example, configuration 1 or configuration 2 in table 1, to the terminal device, so as to ensure the timely transmission of the PDSCH.

Therefore, in this embodiment of the present application, the network device may flexibly configure, according to the delay requirement of the service to be scheduled, the time domain resource of the PUSCH or PDSCH for the terminal device through the first signaling, for example, when the delay requirement of the service to be scheduled is higher, configure the time domain resource with a smaller timing difference for the terminal device, thereby implementing timely scheduling of the service to be scheduled, or when the delay requirement of the service to be scheduled is lower, configure the time domain resource with a larger timing difference, that is, K0/K2, for the terminal device, thereby the terminal device may receive data or transmit data at a lower chip operation speed, which is beneficial to reducing the power consumption of the terminal device.
