Description

The method and apparatus of transmitting uplink data

Technical field

The present invention relates to the communications fields, and more particularly, to the method and apparatus of transmitting uplink data.

Background technique

Exemplary wireless communication network (such as, long term evolution (Long Term Evolution, referred to as " LTE " network) in, the selection that upstream data shares channel (Shared Data Channels) is based on scheduling/allowance (Scheduling/Grant) mechanism, it is controlled completely by base station (Base Station, referred to as " BS ").In the mechanism, user equipment (User Equipment, referred to as " UE ") issues uplink scheduling request to BS first.After BS receives the request, uplink Grant is issued to notify to distribute to the uplink transmission resource of the UE to UE.UE carries out data transmission in the uplink transmission resource by permitting accordingly.

Large-scale access is one of typical case scene of next-generation communication network.When mass users access, if continuing to use above-mentioned Scheduling/Grant mechanism, it on the one hand will lead to the scheduling pressure of huge signalling expense and BS resource allocation, on the other hand will cause significant propagation delay time.In consideration of it, next-generation communication network is to support mass users access that will use to exempt to authorize (Grant Free) transmission mode.Under Grant Free transmission mode, BS delimit the access area of competition transmission unit (Contention Transmission Unit, referred to as " CTU ") in uplink transmission resource.UE accesses uplink transmission resource in the area with competitive way, without following Scheduling/Grant mechanism.

Successfully to carry out Grant Free uplink, UE should determine the CTU resource of uplink first.Determine that CTU resource can be based on predetermined UE-CTU mapping ruler known to UE and BS both sides.The recessive manners such as the mapping ruler can be provided by standard or firmware is realized are UE precognition.It can also be notified by BS by dominant high-level signaling mode.For example, different mapping rulers can be defined in a standard first, the serial number of corresponding mapping ruler is then passed through into signaled UE by BS.

Different UE are allowed to carry out multi-upstream access transmission using same characteristic features wave (Signature).Will be clashed when multiple UE access using identical Signature identical running time-frequency resource (when i.e. identical-frequency-code resource) simultaneously, need accordingly advanced detection method be resolved.When it is multiple using it is identical when-frequency-code resource UE further use same pilot when, conflict be generally considered to be can not merely by detection method solve.Such situation needs to cooperate special conflict avoidance or settlement mechanism, for example remaps, retransmits.To reduce the conflict on particular UE or specific CTU, part UE can remap Onto new CTU resource.

The Grant Free transmission of above-mentioned mass users access will lead to competition conflict, reduce Grant Free transmission reliability due to allowing multiple UE to compete transmission in same CTU resource.To ensure that low time delay high reliability Grant Free is transmitted, it is necessary to which the UE for having particular service demand for part provides additional transmission guarantee.

Therefore, how the reliability of improve data transfer, save system resource overhead the problem of being current urgent need to resolve.

In receive process, for UE_iReception detection ACK/NACK feedback not be directed to I_CTU,ijEach CTU indicated is individually carried out, but in UE_iRedundancy merging is unified ACK/NACK after finishing receiving.

In embodiments of the present invention, optionally, different terminal equipment may carry out transmitting uplink data by identical CTU, clash so as to cause Grant Free initial transmission or HARQ transmission, corresponding mechanism is needed to be resolved.For example, UE1 and UE2 map to CTU602 in TTI1 and carry out initial transmission, therefore there is conflict on CTU602 as shown in Fig. 6 (a).To solve Grant Free transmission collision, conflict terminal device can be respectively mapped to new HARQ resource in TTI2.For example UE1 maps to CTU602, UE2 maps to CTU604.Only have UE2 on CTU604 and carry out HARQ transmission, therefore can successfully detect.CTU602 is upper, and due to there is the initial transmission event of the HARQ transmission of UE1 and UE5 simultaneously, there are still conflicts.To solve Grant Free HARQ transmission conflict, conflict terminal device can be respectively mapped in new HARQ resource in TTI3.For example UE1 maps to CTU608, UE5 maps to CTU602.

In Fig. 6 (b), UE1 and UE2 map to CTU602 and carry out initial transmission, therefore there is conflict on CTU602.Conflict terminal device is respectively mapped to new HARQ resource in TTI2.For example UE1 maps to CTU602, UE2 maps to CTU604.Only have UE2 on CTU604 and carry out HARQ transmission, therefore can successfully detect.CTU602 is upper, and due to there is the initial transmission event of the HARQ transmission of UE1 and UE5 simultaneously, there are still conflicts.To solve Grant Free HARQ transmission conflict, the signal on the CTU602 in the TTI1 clashed can be stored first, then helps to carry out the detection to UE1 and UE5 using the signal of the TTI2 UE2 solved.

Specifically, the receipt signal model in Fig. 6 (b), in TTI1 on CTU602 are as follows:

y₁₁=h₁₁₁x₁+h₁₂₁x₂+n₁₁ (1)

Reception signal in TTI2 on CTU602 and CTU604 is respectively as follows:

y₁₂=h₁₁₂x₁+h₁₅₂x₅+n₁₂ (2)

y₂₂=h₂₂₂x₂+n₂₂ (3)

Wherein, y_ikFor the reception signal on i-th of CTU in k-th of TTI, h_ijkIt indicates on i-th of CTU of k-th of TTI from UE_jTo the channel information of the network equipment, X_jIndicate UE_jTransmitting signal, n_ikIndicate the receiving end noise on i-th of CTU in the TTI of kth.

It is a kind of solve equation (1)~(3) method be to solve X from its independent equation (3) first₂Estimated valueThen according to estimated valueFrom cancellation X in equation (1)₂, and from eliminate X₂Equation afterwardsIn solve X₁Estimated valueFinally according to estimated valueAfter eliminating interference in equation (2), equation is solved

That is, to solve Grant Free HARQ transmission conflict, the CTU604 in TTI2 that can never clash first solves the information of UE2, interference of the UE2 to UE1 is then eliminated in signal from receiving for the CTU602 in TTI1 using the information of the UE2 solved, to release UE1 Information, finally eliminate the interference of UE1 from the reception signal of the CTU602 in TTI2 using the information of the UE1 solved and last solution obtain UE5.
