Description

The judgment means of uplink data channel resource multiplexing type and method

Technical field

The present invention relates to the communications field, relate in particular to the judgment means of uplink data channel resource multiplexing type and the apparatus and method of method and definite transmission block size.

Background technology

In the LTE system, the major function of physical uplink data channel (PUSCH) is carrying uplink business data (UL-SCH), can carry under specific circumstances upstream control signaling (UCI).Wherein, UCI comprises order indication (RI), definite response information (ACK/NACK), channel quality indication (CQI) and pre-coding matrix indication (PMI), for the transmission information relevant to downlink data transmission.

When UCI is carried on the PUSCH channel, have two kinds of resource multiplex types, Class1: PUSCH carries UCI and business datum simultaneously, and namely UCI and business datum adopt frequency division multiplexing (FDM) mode to transmit, as shown in Figure 1, Fig. 1 is that UCI and business datum are at PUSCH frequency division multiplexing schematic diagram; Type 2:PUSCH only carries UCI (in Fig. 1, the running time-frequency resource number of transfer of data is 0 situation).But specifically adopt any resource multiplex type to belong to the equipment problem of implementation (scheduling strategy) of eNodeB, the LTE agreement is not done regulation.When adopting the resource multiplex Class1, because the priority of UCI is high, it will preferentially take running time-frequency resource (RE), make can be used for the RE decreased number of business data transmission, if do not process, to cause the actual bit rate of business datum to improve, thereby reduce it, detect performance, the waste interface-free resources.

UCI number of modulation symbols on PUSCH is: when UCI is carried on the PUSCH channel, dissimilar UCI (RI, ACK and CQI/PMI) encodes respectively and modulates, and encoder bit rate depends on the spectrum efficiency that business datum adopts while transmitting for the first time in PUSCH.The acquisition of different UCI speed is under the condition of given UCI original information bits, by distributing different number of modulation symbols (being the RE number), realizes.

RI counts Q through the modulation symbol after coded modulation _RI' by formula (1), calculated:

Definite scheme of up TBS belongs to the equipment problem of implementation, and the LTE agreement is not done unified regulation.

At present the scheme of a kind of common definite up TBS as shown in Figure 2, comprises four steps:

S202: PRB number and the position of being determined to distribute to UE by the ascending resource distribution module.In the process that resource is distributed, at first according to the PRB number of the current transfer of data demand of UE and broadband CQI (being the SINR of full bandwidth) estimation distribution, then according to subband CQI, further determine to distribute number and the position of PRB.

S204: up AMC module is selected the MCS grade according to the locational time domain SINR of PRB that distributes for UE.That the MCS selection is used is base station measurement revised SINR on each PRB.

S206: obtain MCS index by the MCS selector, according to the mapping relations of MCS index and TBS index, table look-up and obtain TBS index.The mapping form of up MCS index and TBS index is referring to table 7.

S208: by the PRB number N_PRB of TBS index and CU, according to (TBS index, the N_PRB) mapping relations with TBS, obtain the size of TBS by searching the TBS form.Wherein, the TBS form is referring to table 8.

The shortcoming of existing scheme is:

1) when UCI need to transmit on PUSCH, existing scheme did not provide the determination methods of UCI and business datum multiplex mode;

2) when the mode of UCI and business datum employing FDM is transmitted simultaneously on PUSCH, eNodeB does not consider the impact of UCI when determining the TBS of business datum, cause the actual bit rate of business datum to improve, detecting hydraulic performance decline even makes a mistake, thereby cause HARQ to retransmit, the waste interface-free resources.
