How lower mask body introduction control information indicates the second running time-frequency resource in the first running time-frequency resource.

In the first realization method, whether it includes that the second time-frequency provides that control information is used to indicate in the first running time-frequency resource Source, it can be that communications standard specification is arranged that specific second running time-frequency resource, which is located at the specific location in the first running time-frequency resource, terminal Equipment determines the position of the second running time-frequency resource according to the communications standard specification after receiving control information；Alternatively, the network equipment The position of the second running time-frequency resource is indicated to terminal device by high-level signaling, control information, which is used to indicate in the first running time-frequency resource, is No includes the second running time-frequency resource, and terminal device receives and determines the second running time-frequency resource according to the instruction of high-level signaling after control information Position；Or the network equipment indicates a part of location information of the second running time-frequency resource by high-level signaling to terminal device, Control information is additionally operable to another part location information of the second running time-frequency resource in the first running time-frequency resource of instruction included, terminal device The position of the second running time-frequency resource is determined according to high-level signaling and control information.

Specifically, the network equipment is by high-level signaling, such as wireless heterogeneous networks (Radio Resource Control, RRC) include in signaling or media access control (Media Access Control, MAC) signaling the first running time-frequency resource of instruction Second running time-frequency resource.For example, high-level signaling carries instruction information, instruction information instruction is by this when the transmission of a block of information When controlling message scheduling, when the first running time-frequency resource corresponding with the carrying third running time-frequency resource of the block of information includes second Frequency resource.The format of the control information is can be with X (Format X).

That is, the network equipment is enabled by the high-level signaling or activated terminals equipment carries out channel state information It reports.

In another implementation, the network equipment can explicitly use the control information to terminal device instruction first The second running time-frequency resource for including in running time-frequency resource, if the control information includes a field, which at least can serve to indicate that It include the second running time-frequency resource in the first running time-frequency resource of terminal device.The network equipment implicitly can use the control information to terminal Equipment indicates to include the second running time-frequency resource in the first running time-frequency resource, and if the control information includes a field, which at least may be used Channel state information corresponding with the first running time-frequency resource is reported for instruction terminal equipment needs, for obtaining the channel shape Second running time-frequency resource of state information includes in the first running time-frequency resource.

That is, meeting simultaneous is sent on the second running time-frequency resource when the network equipment sends first information block Zero energy reference signal.It is referred to the second running time-frequency resource it should be understood that sending zero energy reference signal on the second running time-frequency resource Vacant, in other words, the network equipment carries any transmission signal without using the second running time-frequency resource, and in other words, the network equipment is being sent Signal power corresponding with the second running time-frequency resource is set as zero when signal.

Further, control information is additionally operable to instruction terminal equipment and carries out interference measurement, tool according to the second running time-frequency resource Body, terminal device is measured using corresponding second running time-frequency resource of above-mentioned zero energy reference signal to be interfered and obtains interference measurement knot Fruit.

When the first information block of third running time-frequency resource carrying is URLLC business, the relatively large period in traditional solution Interferometry resource cannot be satisfied the requirement of URLLC business high reliability, therefore, terminal device use and third running time-frequency resource The second running time-frequency resource corresponding to corresponding zero energy reference signal can obtain more fine interference measurement results.The interference Measurement result helps to improve the accuracy of terminal device channel estimation, and then improves the performance of terminal device demodulating and decoding.

Step 405, the terminal device obtains the corresponding letter of first running time-frequency resource according to the interference measurement results Channel state information.

Specifically, terminal device can determine the corresponding channel shape of first running time-frequency resource according only to interference measurement results State information can also determine the corresponding channel status of first running time-frequency resource according to interference measurement results and channel measurement Information.

It should be understood that above-mentioned channel state information can be the energy of interference signal, and channel quality instruction, network equipment scheduling Data transmission uses the index of MCS using the index of MCS, CQI indexes, the difference of CQI indexes, network equipment schedule data transmission Difference, the size or bandwidth of a frequency domain resource, pre-coding matrix instruction, order instruction or transmission number of repetition among It is at least one.

For example, the channel state information can be the energy of interference signal.Terminal device can be according to interference measurement knot Fruit determines the absolute figure (such as magnitude of power) of interfering energy, and the absolute figure of the interfering energy is determined as the first time-frequency money The corresponding channel state information in source；Terminal device can also determine interfering energy according to interference measurement results, according to channel measurement As a result it determines and receives signal energy, then the opposite of receipts signal energy is connected to each other as with reference to by interfering energy to receive signal energy Numerical value (such as decibel dB numerical value) is used as the channel state information.

In another example, the channel state information can be that channel quality indicates (Channel Quality Indicator, CQI)).Terminal device can determine to meet according to interference measurement results and channel measurement (in other words can Reach) Modulation and Coding Scheme (Modulation of the target Block Error Rate (Block Error Rate, BLER) of first information block And Coding Scheme, MCS), and selection indexes the index of maximum target MCS from the MCS for meet condition, alternatively, from Meet the index that the highest target MCS of code check is selected in the MCS of condition, alternatively, the efficiency of selection highest from the MCS for meet condition Target MCS index, the index of target MCS is determined as the corresponding CQI of the first running time-frequency resource.Wherein, said one tune It includes a kind of modulation system and a kind of scheme of coding mode, specifically, a kind of above-mentioned coding mode that encoding scheme processed, which is one, Can be a kind of prespecified modulating-coding of Communications Protocol Specification and a kind of code rate, a kind of above-mentioned Modulation and Coding Scheme A corresponding efficiency numbers, the exponent number that the efficiency numbers are equal to its corresponding modulation system are multiplied by its corresponding code rate.

In another example, the channel state information can be the difference of a MCS index, can be referred to as Delta MCS.Terminal device can determine the target for meeting first information block according to interference measurement results and channel measurement The MCS of Block Error Rate, and the maximum target MCS indexes of MCS indexes are selected from the MCS for meet condition, then by the maximum target MCS indexes are determined as the corresponding channel state information of the first running time-frequency resource with the difference of the MCS indexes of the control information instruction.

In another example, the channel state information can be the size or bandwidth of a frequency domain resource.Eventually End equipment can determine target Block Error Rate and the use for meeting first information block according to interference measurement results and channel measurement It is described control information instruction MCS need running time-frequency resource bandwidth, and using the bandwidth information of the bandwidth as with the first time-frequency The corresponding channel state information of resource, the bandwidth are the sizes of the frequency domain shared by the running time-frequency resource (for example, showing as The number of resource block or the number of resource block group).Wherein, it is false when the terminal device determines the bandwidth of the running time-frequency resource If the time domain size shared by the running time-frequency resource is identical as the time domain size shared by third running time-frequency resource or the running time-frequency resource shared by Time domain size made an appointment by communications standard specification.

In addition, the channel state information can with pre-coding matrix instruction (Precoding Matrix Indicator, PMI), alternatively, order instruction (Rank Indicator, RI), or it disclosure satisfy that the transmission number of repetition of target BLER.

Step 406, the terminal device sends the channel state information to the network equipment.

Specifically, when the first running time-frequency resource is the running time-frequency resource on the n-th-k time domain units, terminal device can be predetermined It is sent to the network equipment on the time domain unit of justice or the time domain unit (for example, n-th of time domain unit) specified from the network equipment Measure obtained channel state information, wherein when the network equipment and the terminal device work in FDD system, N-th-the k time domain units are the n-th-k downlink time domain units, which is n-th of uplink time domain unit, when When the network equipment and the terminal device work in TDD system, the n-th-k time domain units can be used under carrying Row signal, n-th of time domain unit can be used for carrying uplink signal, and n is integer, and k is natural number.

Therefore, because the channel state information that terminal device obtains is reliable much sooner, the network equipment can be set according to terminal The channel state information of standby feedback, the MCS that adjustment uses when being retransmitted to first information block are conducive to the reliable of raising business transmission Property, meet the low time delay requirement of business.
