Description

The indicating means and terminal of channel transmission state

Technical field

The present invention relates to the communications fields, and the indicating means and terminal of state are sent in particular to a kind of channel.

Background technique

With the continuous development of the prior art, mobile communication is developed to forth generation by the first generation.Wherein, forth generation is mobile The standard of communication system is relatively uniform in the world, is International Organization for standardization 3GPP (The third Generation Partnership Project) formulate long term evolution (Long Term Evolution/Long Term Evolution- Advanced, LTE/LTE-A), downlink is based on orthogonal frequency and mostly directly enters (Orthogonal Frequency Division Multiple Access, OFDMA), uplink is based on single carrier frequency division and mostly directly enters (Single Carrier-Frequency Division Multiple Access, SC-FDMA) access way, according to flexible bandwidth and adaptive modulating-coding Mode has reached downlink peak rates 1Gbps, the high-speed transfer of upstream peak rate 500Mbps.

By the authorization limited frequency spectrum that operator is possessed, therefore, it is desirable to by being expanded using unlicensed spectrum resource The capacity of LTE.Based on demand above-mentioned, 3GPP has formulated LTE in the standard i.e. LAA (Licensed- of unauthorized band operation Assisted Access, the i.e. access of authorization auxiliary).Unauthorized frequency range resource before use, needing to carry out channel-monitoring to keep away Exempt to interfere and collide, when judging that present channel is not occupied by other users, just meeting busy channel, this mechanism are referred to as elder generation (Listen-Before-Talk, LBT) is said after listening.Downlink transmission method is had standardized in the LAA of LTE R13, in LTE Ascending transmission method will be also standardized in eLAA the and MuLTEfire alliance of R14.LBT and downlink transfer are by base in downlink It stands side completion, and downlink data (such as PDSCH, Physical Downlink Shared can be sent at once after LBT success The abbreviation of Channel, i.e. Physical Downlink Shared Channel).It is different from downlink, upstream data (such as PUSCH, Physical The abbreviation of Uplink Shared Channel, i.e. Physical Uplink Shared Channel) and LBT by terminal UE (User Equipment's Abbreviation, i.e. user terminal) it completes, and uplink scheduling authorization signaling (UL grant) is sent before at least 4ms by base station, such as scheme Shown in 1, the UL grant on carrier wave and unauthorized carrier wave is authorized to send at the n-4 moment, is used to indicate unauthorized at the n moment The resource location of PUSCH on carrier wave.

Since the UL grant of eNB (abbreviation of evolved Node B, i.e. base station) is at least before the PUSCH transmission of UE 4ms send, therefore eNB when sending UL grant can not it is expected that UE LBT as a result, not can guarantee UE can scheduling when Upstream data is sent in frequency resource, for example, UE may fail due to LBT, PUSCH can not be sent.For in unauthorized frequency range For the UE for transmitting uplink, 1) the reason of not sending uplink (Discontinuous Transmission, DTX) includes: (E) PDCCH (Physical Downlink Control Channel, i.e. physical down control of traditional transmission UL grant Channel) reception failure；2) before the exclusive UE of unauthorized frequency range sends upstream data on the running time-frequency resource of scheduling, the LBT of UE Do not succeed.In authorized spectrum band, eNB can judge DTX by way of energy measuring, but in unauthorized frequency range, due to other Equipment equally understand the reason of busy channel and cause energy measuring judgement inaccuracy, namely unauthorized frequency range transmission due to The influence of interference and collision, the error probability that will lead to the UL grant transmitted in unauthorized frequency range rises, and then DTX probability Rise, while the competitive properties of unauthorized frequency range will lead to the LBT probability of failure (i.e. LBT is not in the success of scheduled transmission moment) of UE Increase with channel user number and increase, DTX probability can be further increased.

To sum up, eNB can not be identified effectively in the biggish DTX event of unauthorized frequency range probability of happening, that is, UE cannot be distinguished The situation of DTX (terminal does not send uplink) and PUSCH transmission mistake.When eNB to UE since DTX is without the resource of transmission When signal on position is demodulated, CRC (abbreviation of Cyclic Redundancy Check, i.e. cyclic redundancy are inevitably resulted in Bit check) check errors.If eNB is considered PUSCH transmission mistake and is cached, HARQ (Hybrid is initiated Automatic Repeat reQuest, i.e. hybrid automatic repeat-request) when retransmitting, it will lead to and receive the property that merges next time It can decline；If when eNB caching is the signal that other equipment are sent, influence is especially serious when terminal does not send uplink, Therefore ascending HARQ processing can not effectively be carried out.

Channel can not be correctly provided for ascending transmission method in the prior art and sends state, and uplink is caused to be imitated The low problem of rate, currently no effective solution has been proposed.
