Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method and apparatus that carries out up channel or signal transmission in the system that has adopted carrier aggregation technology.
Background technology
Long Term Evolution (Long Term Evolution; Abbreviation LTE) uplink physical channel of system comprises Physical Random Access Channel (Physical Random Access Channel; Abbreviate PRACH as), Physical Uplink Shared Channel (Physical Uplink Shared Channel; Abbreviate PUSCH as), Physical Uplink Control Channel (Physical Uplink Control Channel abbreviates PUCCH as).Wherein the effect of PRACH channel mainly is to realize uplink synchronous and sub-district switching.The up employing DFT-S-OFDMA of LTE (DFT-Spread OFDM, DFT expands OFDM) technology, reference signal and data are multiplexing together through the mode of Time Division Multiplexing.Uplink reference signals is divided into demodulated reference signal (Demodulation Reference Signal; Be called for short DMRS) and detection reference signal (Sounding Reference Signal; Be called for short SRS); Wherein the main effect of SRS is the measurement that is used for up channel, is convenient to eNB and does frequency selective scheduling, is a kind of " broadband " reference signal.
In the LTE system,, cause the time of a plurality of UE signals arrival eNB also inequality because different user equipment (User Equipment abbreviates UE as) is different apart from the position of base station (abbreviating eNB as).Real system is to be benchmark the time with eNB, therefore just needs to estimate that different UE arrives the time delay of base station, guarantees that the signal of different UEs is received by eNB at one time.The mode that UE uses the PRACH channel to send targeting sequencing (preamble) can be used for measuring the time delay of different UEs to the base station, realizes uplink synchronous.In the process that switch the sub-district, the PRACH channel is realized the quick switching of minizone through sending targeting sequencing target BS synchronously simultaneously.Random access procedure between user and the sub-district is divided into two kinds of competitive way and non-competing modes.Random access procedure based on competitive way need collide processing, does not then need based on the random access procedure of non-competing mode.
In order to satisfy (the International Telecommunication Union-Advanced of senior International Telecommunications Union; Abbreviate ITU-Advanced as) requirement; Senior Long Term Evolution (Long Term Evolution Advanced as the evolution standard of LTE; Abbreviating LTE-A as) system need support bigger system bandwidth (reaching as high as 100MHz), and need backward compatibility LTE prior standard.On the basis of prior LTE system; Can the bandwidth of LTE system be merged and obtain bigger bandwidth; This technology is called carrier aggregation (Carrier Aggregation; Abbreviate CA as) technology, the availability of frequency spectrum, alleviation frequency spectrum resource that this technology can improve the IMT-Advance system are in short supply, and then optimize the utilization of frequency spectrum resource.
In the system that has introduced carrier aggregation, the carrier wave that carries out polymerization is called component carrier (Component Carrier abbreviates CC as), is also referred to as a sub-district (Cell).Simultaneously; Principal component carrier wave/sub-district (Primary Component Carrier/Cell has also been proposed; Abbreviate PCC/PCell as) and the notion of auxilliary component carrier/sub-district (Secondary Component Carrier/Cell abbreviates SCC/SCell as), in the system that has carried out carrier aggregation; At least comprise a principal component carrier wave and auxilliary component carrier, wherein the principal component carrier wave is in state of activation always.
Because the LTE-A system has introduced the notion of carrier aggregation, possibility that exists a plurality of up channels to send simultaneously particularly under other Cell have kept synchronous prerequisite, if permission SCell does random access procedure, just need be sent PRACH on SCell.The possibility that just exists this moment PRACH and the up channel on other Cell and signal on the SCell to send simultaneously.
