Description
Technical field
The present invention relates to wireless communication technology field.More specifically, the present invention relates to a kind of mixed self-adapting repeating method and equipment for uplink coordinated multicast system.
Background technology
In third generation partner plan (3GPP) the 53rd RAN meeting, passed through a work clause about cooperative multipoint transmission.This work clause is proposed research operation relevant with uplink coordinated multicast communication in isomorphism and heterogeneous network configuration.In addition, in the 67th meeting of 3GPP RAN1, receive publicity and be discussed in detail separately about the motion of uplink coordinated multicast communication.
In the scene of numerous uplink coordinated multicast communications, the asymmetric scene of a kind of uplink downlink has been subjected to paying close attention to widely.In the uplink coordinated multicast communication of reality, when user equipment to transmit ascending data, if the size of the power that system can receive according to its peripheral base station, freely select one or more base station to receive the upstream data of user device transmissions, then the performance of system can access very big improvement, thereby simultaneously the transmitting power of subscriber equipment can be reduced and prolongs its battery service time.
The received power of receiving terminal depends primarily on the size of transmitting terminal transmitting power and the path loss between transmitting terminal and the receiving terminal.For up link, subscriber equipment is unique transmitting terminal, and its peripheral base station all can be used as receiving terminal, and the received power of different base station receiving terminals is different and different according to the path loss between subscriber equipment and each base station.For homogeneous network, because the transmitting power of all base station transmitting terminals is the same, the received power of all receiving terminal subscriber equipmenies only depends on the path loss between each base station and the subscriber equipment.In homogeneous network, optimum descending transmitting terminal base station is optimum up receiving terminal base station.
Yet, for heterogeneous network, because the base station has different down transmitting powers with little base station, can cause for some subscriber equipmenies, the descending transmitting terminal base station of its optimum may not be the up receiving terminal base station of optimum.Fig. 1 shows the sample scenario of the cooperative multipoint transmission in the heterogeneous network.As shown in Figure 1, although base station 10 is bigger to the path loss of subscriber equipment 30 than little base station 20 to the path loss of subscriber equipment 30, but because base station 10 has stronger transmitting power than little base station 20, therefore 10 power that receive are also bigger from the base station for subscriber equipment 30, so subscriber equipment 30 is selected from the base station 10 downlink data receivings.In addition, because the little base station of subscriber equipment 30 distance 20 is nearer, then its path loss is corresponding just little, so subscriber equipment 30 is selected to send upstream datas to little base station 20.
In the asymmetric scene in up-downgoing path shown in Figure 1, need the transmission problem of physical mixed self adaptation retransmission indicating chanel (PHICH) in the resolution system.Particularly, in the version of the Release-8/9/10 of LTE, when some subscriber equipmenies are assigned to the ascending resource transmit ascending data at subframe k, this subscriber equipment then can detect corresponding PHICH resource at subframe k+4, thereby obtains the ACK/NACK information that subframe k goes up the upstream data of transmission.According to the definition among the up-to-date LTE Rel-10, the resource of PHICH is associated with the lowest index number of the ascending resource that distributes before.In the scene of traditional uplink downlink symmetry, the cyclically shifted sequences of a specific demodulation reference signaling (DMRS) and the lowest index number of a PUSCH ascending resource are determined a unique PHICH resource.
Yet in scene shown in Figure 1, base station 10 sends Downlink Control Information for subscriber equipment 30, comprises in this control information that the up PUSCH of subscriber equipment 30 transmits the cyclically shifted sequences of the demodulation reference signaling of resource needed and use.Because this subscriber equipment 30 sends the PUSCH data to little base station 20, then the ascending resource of its use in principle can be multiplexing by other subscriber equipment institutes in the macrocell, thereby improve power system capacity.At this moment, if subscriber equipment 30 continues to continue to use the PHICH resource allocation process among the LTE Rel-8/9/10, then can cause the PHICH resource of a plurality of subscriber equipmenies to bump.
