Description

The sending method of a kind of up channel, base station and subscriber equipment
Technical field
The present invention relates to the communications field, particularly relate to a kind of new uplink measurement reference signal (SoundingReferenceSignal is called for short SRS) and the sending method of PUCCH and PUSCH, base station and subscriber equipment in the system that have employed carrier aggregation technology.
Background technology
Long Term Evolution (LongTermEvolution, it being called for short LTE) uplink physical channel of system includes Physical Random Access Channel (PhysicalRandomAccessChannel, referred to as PARCH), Physical Uplink Shared Channel (PhysicalUplinkSharedChannel, referred to as PUSCH), Physical Uplink Control Channel (PhysicalUplinkControlChannel, referred to as PUCCH). The up employing single carrier OFDM (OrthogonalFrequencyDivisionMultiplexing of LTE, OFDM) technology, reference signal and data are to be multiplexed together by the mode of TDM (TimeDivisionMultiplexing, time division multiplex). Uplink reference signals is divided into demodulated reference signal (DemodulationReferenceSignal, referred to as DMRS) and measuring reference signals (SoundingReferenceSignal, referred to as SRS), wherein, DMRS is divided into PUCCH solution to call reference signal and PUSCH solution calls reference signal, is respectively used to different transmissions. The Main Function of DMRS is the estimation for up channel and base station (referred to as eNB) holds relevant detection and demodulation, the Main Function of SRS is the measurement for up channel, it is simple to eNB does frequency selective scheduling. In order to support this frequency selective scheduling, subscriber equipment (referred to as UE, UserEquipment) needs, to bigger bandwidth measurement, generally all to exceed the bandwidth of data transmission, and therefore SRS is a kind of " broadband " reference signal. In LTE, it is disposable or periodically send SRS that eNB can dispatch each UE, and when periodically sending, its transmission cycle can be 2/5/10/20/40/80/160/320 millisecond. In the cycle of SRS transmission and cycle, the side-play amount of subframe is determined by the signaling SRSConfigurationIndex of the specific 10Bit of UE. UE sends the SRS bandwidth used and depends on sending in the transmit power of UE, community the UE number etc. of SRS. Use bigger transmission bandwidth can obtain more accurate uplink signal-channel quality to measure, but when up path loss is bigger, UE needs bigger transmitting power to maintain the transmitting power density of SRS. For each system bandwidth, being configured with SRS bandwidth aggregation 8 kinds different in LTE, in each set, the UE that can be different in LTE distributes the different SRS bandwidth up to 4 kinds.
LTE specifies transmission on SRS last symbol in subframe, and simultaneously in order to avoid interfering between SRS and the PUSCH data between different user, LTE specifies that last symbol of corresponding subframe can not be used for sending PUSCH data by any UE. Generally, such regulation ensure that PUCCH and SRS will not conflict mutually. If there is SRS and PUCCH to send simultaneously, then lose SRS, to keep the single-carrier property of up-link. When the form of PUCCH is PUCCHFormat1/1a/1b (spatial structure is as shown in Figure 1), it is stipulated that the PUCCH format of truncate, as in figure 2 it is shown, now, last symbol of subframe may be employed to send SRS's. When SRS and PUCCHFormat2/2a/2b or SR (SchedulingRequest) conflicts, often lose SRS, only when with ACK/NACK simultaneous interpretation, it is possible to select PUCCH and the SRS of truncate to transmit simultaneously.
LTE-A (LTEAdvanced, referred to as LTE-A) system is the evolution system of future generation of LTE system, which introduces the concept of carrier aggregation (CarrierAggregation). the LTE system bandwidth of described carrier aggregation is considered as component carrier (ComponentCarrier frequency spectrum), each component carrier can also be called a Serving cell (servingCell), and namely a frequency spectrum can be polymerized by n component carrier frequency (Serving cell). resource for a R10UE (UserEquipment) is to be made up of n the Serving cell (component carrier) of frequency domain, wherein, one community is called main plot (Primarycell), and all the other communities are called secondary cell (Secondarycell). up support SU-MIMO, and 4 antennas can be used at most as transmitting antenna, that is UE can send SRS at synchronization on many antennas simultaneously, and eNB needs to estimate the status information on every channel according to the SRS received on every antenna. under the scene of carrier aggregation, PUCCH be integrally fixed on some upstream components carrier wave send, this will cause that the probability that ascending control channel and SRS send simultaneously becomes big, if still adopting the method destroying SRS, by the estimation of the measurement and downlink channel condition that affect up channel, and, lte-a system being supported, PUCCH and PUSCH sends simultaneously, that is in LTE-A, up single carrier is not the major consideration that up channel sends design, therefore, in LTE-A, the transmission of various up channels can adopt the mode different from LTE to carry out. it is therefore desirable to rethink under carrier aggregation scene, the sending method of various up channels.
