Further, in the prior art, the beam for transmitting data corresponds to only one basic parameter set for one transmitting side and one receiving side, that is, the time domain basic parameter set and the frequency domain basic parameter in the prior art. The set is 10 ms per radio frame, one radio frame contains 10 subframes, one subframe contains two time slots, and one time slot contains seven symbols. Twelve consecutive subcarriers in the frequency, one time slot in the time domain constitutes one RB, each subcarrier spacing is 15k, one subcarrier in the frequency domain, one symbol in the time domain is one. It is fixedly defined so as to be called two REs.

In the embodiment of the present invention, there may be a plurality of basic parameter sets for one transmitting side and one receiving side, that is, the first basic parameter set and the second basic parameter set in the plurality of basic parameter sets. The set may have the same time domain basic parameter set, different frequency domain basic parameter sets, or the first basic parameter set and the second basic parameter set have the same frequency domain basic parameter set, different time domain basic parameter sets. Or the frequency domain basic parameter set of the first basic parameter set and the second basic parameter are different, the time domain basic parameter set is also different, or the time of the first basic parameter set and the second basic parameter set The embodiment of the present invention is not limited to this because the domain basic parameter set is different, the frequency domain basic parameter set is the same, the spatial domain basic parameter set is the same, and the like.

For easy understanding, for example, 5 ms is included for each radio frame of the first basic parameter set, 8 ms is included for each radio frame of the second basic parameter set, and these two time domain basic parameter sets are included. Each subframe of the first basic parameter set contains four time slots and each subframe of the second basic parameter set contains three time slots, which may be considered different. The parameter sets may be considered different, with each time slot in the first basic parameter set containing 12 symbols and each time slot in the second basic parameter set containing 8 symbols, these two times. It may be considered that the region basic parameter sets are different, the subcarrier spacing of the first basic parameter set is 10k and the subcarrier spacing of the second basic parameter set is 20k, these two frequency domain basic parameters. The sets may be considered different, with each fundamental frequency domain unit in the first fundamental parameter set containing 15 consecutive subcarriers and each fundamental frequency domain unit in the second fundamental parameter set being 8 consecutive.

For example, different basic parameter sets may be different REs, different RBs, different scheduling blocks (Scheduling Block: abbreviated as "SB"), for example, the RE of the first basic parameter set is 8 and the second. It may be considered that the RE of the basic parameter set is 10 and the first basic parameter set and the second basic parameter set are different, and the RB of the first basic parameter set contains 6 REs and the second. It may be considered that the RB of the basic parameter set contains 10 REs and the first basic parameter set and the second basic parameter set are different, and the SB of the first basic parameter set contains 20 RBs. It may be considered that the SB of the second basic parameter set contains 15 RBs and the first basic parameter set and the second basic parameter set are different, thereby causing different REs, RBs or SBs in the data transmission process. Data can be transmitted as a data unit and can be adapted to the data diversification needs of the network.

Optionally, the time domain resource mapping scheme can also include a time frequency resource allocation scheme, eg, one time slot in the first basic parameter set contains eight symbols, the first, third, and eighth. The control plane data can be transmitted by symbols, and one time slot of the second basic parameter set contains 12 symbols, and the control plane data can be transmitted by the second, ninth and tenth symbols. ..

The beam is transmitted using one basic parameter set and the beam is transmitted using the second basic parameter set with a bandwidth of 10 to 20 Mhz.

It should be understood that the above exemplary description of the different basic parameter sets is for ease of understanding only, the basic parameter set may be numerology, any of the elements in the time frequency domain resource numerology. The different basic parameters generated by this modification are within the scope of protection of the embodiments of the present invention.

It should be understood that the transmitting side may be a terminal device, the receiving side may be a network device, or the transmitting side may be a network device, and the receiving side may be a terminal device. Also, the embodiments of the present invention are not limited to this.

As one selectable embodiment, different basic parameter sets include different power calculation methods, and different power calculation methods include open-loop power calculation methods and closed-loop power calculation methods.

It should be understood that closed-loop power calculation means that the transmitting side calculates the transmission power of the signal based on the feedback information transmitted from the receiving side, and open-loop power calculation means that the transmitting side receives feedback from the receiving side. It is not necessary, and it is obtained by calculating the transmission power of the signal based on the measurement information of itself. For example, the open-loop power calculation method does not require the terminal device to receive information feedback from the network device, determines the transmission power of the network device pilot based on the system message, or determines the current received pilot power. By measuring and estimating the downlink loss, it may be possible to approximate the downlink loss as the uplink loss and calculate the uplink transmission power based on the uplink interference signal or the like. .. The closed-loop power calculation method may be such that the terminal device dynamically determines the signal transmission power of the terminal device based on the signal reception power of the network device.

As one selectable embodiment, the transmitting side establishes the first target basic parameter set of the first beam for transmitting the first data in N basic parameter sets. One channel is one basis, including determining the data type of the first data and the sender determining the first target basic parameter set according to the data type of the first data. It can be understood that a parameter set may be supported or a plurality of basic parameter sets may be supported.

As one selectable embodiment, the data type of the first data corresponds to M basic parameter sets, the N basic parameter sets include the M basic parameter sets, and M is 2 or more. And M is less than N, where the sender establishes the first target basic parameter set according to the data type means that the sender determines M according to the data type. It includes establishing the basic parameter set and determining the first target basic parameter set in the M basic parameter sets.

Further, the different data types may be at least one of the control plane data and the user plane data, for example if the first data is the control plane data, the control channel corresponds to a plurality of different basic parameter sets. If the primary data is user plane data, then the service channel can accommodate multiple different underlying parameter sets, and of course, if both user plane data and control plane data are present, then the control channel. Can correspond to one basic parameter set, the service channel can correspond to another basic parameter set, and the control channel and the service channel can correspond to the same basic parameter set, and the embodiments of the present invention are not limited thereto. ..

Further, the data types may be defined according to different data, and the data can be divided into two types, control plane data and user plane data, and the physical uplink control channel (Physical) for the control plane data. It can support two channels, U-link Control Channel (abbreviated as "PUCCH") and Physical Downlink Control Channel (abbreviated as "PDCCH"), and can support physical downlink for user plane data. It can support two channels, a shared channel (Physical Downlink Shared Channel: abbreviated as "PDSCH") and a physical uplink shared channel (abbreviated as "PUSCH"), and can also support, for example, downlink data. On the other hand, the channel can be divided according to different data types, for example, a broadcast channel (Physical Broadcast Channel: abbreviated as “PBCH”) and a downlink shared data channel (Physical Downlink Shared Channel: abbreviated as “PDSCH”). , Control Format Instruction Channel (Physical Control Method Indicator Channel: abbreviated as "PCFICH"), Downlink Control Channel (Physical Downlink Control Channel: abbreviated as "PDCCH"), HARQ Instruction Channel "Physical" It can be divided into physical multicast channel (abbreviated as "PMCH"), reference signal (reference signal: abbreviated as "RS") and synchronization signal (synchronization signal: abbreviated as "SCH"). , I will not list the uplink channel divisions one by one here. One physical channel described above can correspond to one basic parameter set, one physical channel can correspond to multiple basic parameter sets, and the same physical channel can correspond to multiple different resource positions. It can be understood that different resource locations can use different basic parameter sets, different resource locations have the same time domain, frequency domain, but different spatial domains, i.e., time domain and spatial domain. May be understood to be the same but different in frequency domain, and may be understood to be the same in frequency domain and spatial domain but different in time domain, i.e. at least of the time domain, frequency domain and spatial domain. If one is different, it may be defined as two different resource positions. Selectably, different physical channels can correspond to different basic parameter sets, and the embodiments of the present invention do not limit the correspondence between the channels and the basic parameter sets.

As one selectable embodiment, if the data type of the first data is control plane data, the sender is in the time domain resource, the space domain resource and the frequency domain based on the first target basic parameter set. Prior to transmitting the first beam, the method further comprises processing the third beam by the transmitting side based on a beamforming algorithm to obtain the first beam.

Specifically, in antenna technologies such as multi-input and multi-output (Mu1type-Input Mu1type-Output: abbreviated as "MIMO"), beamforming processing is performed on the third beam on the control channel to obtain directional data. It is possible to generate a single beam, etc., and selectively perform beamforming processing on the data transmitted on the data channel, and perform beamforming processing on the data transmitted on the control channel. Also, the embodiments of the present invention are not limited to this.

As one selectable embodiment, the method further establishes a second target basic parameter set for the second beam for the transmitter to transmit the second data in N basic parameter sets. The data type of the second data is different from the data type of the first data, the second target basic parameter set is different from the first target basic parameter set, and the sender is a time domain resource, a spatial domain resource, and the like. And the frequency region resource comprises transmitting the second beam based on the second target basic parameter set.

It should be understood that the first and second data may be the same data or different data, i.e. the first beam and the second beam may transmit the same data. Often, the same data here may be the same service data or the same control data, the different data may be different service data or different control data, or the first data may be service data. The second data may be control data, and the embodiments of the present invention are not limited thereto.

In one selectable embodiment, the first data and the second data are the same and the sender is the time domain resource, the spatial domain resource, and the frequency domain resource to the first target basic parameter set. Based on that, before transmitting the first beam, the method further causes the transmitting side to transmit beam resource configuration information to the receiving side, and the beam resource configuration information to transmit the first data. It is used to indicate the position of the first resource occupied by the first beam, the position of the second resource occupied by the second beam for transmitting the second data, and the receiving side is the beam resource. It includes processing the first data and the second data based on the configuration information.

Specifically, when the transmitting side is a network device and the receiving side is a terminal device, the network device can transmit the beam resource configuration information to the terminal device, and the beam for transmitting the same data as the beam resource configuration information. Used to indicate the resource location occupied by the terminal, when the terminal device receives the beam resource configuration information, it is possible to determine two different resource positions of the beam for transmitting the same data, thereby this. A combined gain calculation can be performed on the data received at two different resource locations.

As one selectable embodiment, the first data and the second data are the same, and the transmitter is in the time domain resource, the space domain resource, and the frequency domain resource to the first target basic parameter set. Based on that, before transmitting the first beam, the method further comprises acquiring the time interval period by the transmitting side, where the transmitting side is in the time domain resource, the space domain resource, and the frequency domain resource. Transmitting the first beam based on the first target basic parameter set means that the transmitting side uses the first target basic parameter set at the first time point based on the time interval period. Including transmitting the first beam, that the transmitting side transmits the second beam in the time domain resource, the space domain resource, and the frequency domain resource based on the second target basic parameter set. The transmitting side comprises transmitting the second beam at the second time point using the second target basic parameter set based on the time interval period, the first time point and the second time point. The time point is an adjacent time point at which the same data is transmitted based on the time interval period, and the first target basic parameter set and the second target basic parameter set are different.

As one selectable embodiment, the first data and the second data are the same, and the transmitter is in the time domain resource, the space domain resource, and the frequency domain resource to the first target basic parameter set. Based on this, the method further comprises acquiring the resource interval by the transmitting side, wherein the transmitting side is in the time domain resource, the spatial domain resource, and the frequency domain resource. Transmitting the first beam based on the first target basis parameter set means that the transmitter uses the first target basis parameter set in the first frequency domain resource based on the resource interval. Including transmitting the first beam, that the transmitting side transmits the second beam in the time domain resource, the space domain resource, and the frequency domain resource based on the second target basic parameter set. The transmitting side comprises transmitting the second beam in the second frequency domain using the second target basic parameter set based on the resource interval, the first frequency domain resource and the first. The second frequency domain resource is an adjacent resource for transmitting the same data based on the resource interval.

Specifically, it is possible to set a cycle interval and confirm that the transmitting side transmits the same data to the receiving side at each cycle interval, and the cycle interval may be an interval of time, whereby the terminal may be used.
