Description

A kind of resource distribution indicating means of backhaul link uplink control channel and system

Technical field

The present invention relates to moving communicating field, particularly relate to a kind of resource distribution indicating means and system of the ascending control channel for back haul link.

Background technology

Relaying technique, as a kind of emerging technology, causes and notes more and more widely, is regarded as the key technology of B3G/4G.Because future wireless system or cellular system require to improve the network coverage, support higher rate transmission, this proposes new challenge to wireless communication technology.Meanwhile, the cost issues of system building and maintenance is more outstanding.Along with the increase of transmission rate and communication distance, the energy consumption issues of battery also becomes outstanding, and the radio communication in future will adopt higher frequency, and the pathloss attenuation caused thus is more serious.By relaying technique, traditional one hop link can be divided into multiple multi-hop link, due to Distance Shortened, this greatly will reduce path loss, contribute to improving transmission quality, expand communication range, thus provide quicker better service for user.

At introducing relay station (RN, RelayNode) in network, as shown in Figure 1, evolved base station (eNB) and macrocell user (M-UE in network, MacroUserEquipment) link between is called the link that direct transfers, link between eNB and RN is called back haul link, and the link between RN and relay domain user (R-UE, RelayUserEquipment) is called access link.

Direct transfer on link in LTE system, ascending physical signal control channel (the PUCCH of M-UE, the information that can carry PhysicalUplinkControlChannel) has: dispatch request (SR, Schedulingrequest), HARQ feedback information and channel quality reporting.Wherein, HARQ feedback information and the data receiver situation of M-UE to the descending transmission of eNB carry out ACK/NACK feedback; Channel quality reporting comprises channel quality instruction (CQI, ChannelQualityIndicator), pre-coding matrix instruction (PMI, PrecodingMatrixIndicator) or order instruction (RI, RankIndication).M-UE adopts corresponding ascending control channel form to launch according to the different situations of reporting information, is respectively PUCCHformat1/1a/1b and PUCCHformat2/2a/2b.

In LTE system, 1 subframe is 1ms, is divided into 2 time slots (slot) of 0.5ms, and ascending physical signal resource is with Physical Resource Block (RB, ResourceBlock) for unit divides, and it is 1 slot that RB is defined as in time-domain, comprises continuous print individual SC-FDM symbol.Wherein, when frame structure employing general cyclic prefix (NormalCyclicPrefix) of system, when frame structure employing extended cyclic prefix (ExtendedCyclicPrefix) of system, it frequency domain is continuous print individual subcarrier, in units of RB, RB call number n can be used to the distribution of ascending physical signal resource _pRBindicate, wherein, for the RB quantity that up-link bandwidth comprises.

The physical source distributing of PUCCH channel by RB in units of, each PUCCH physical channel takies a pair RB couple, each slot takies respectively a RB, frequency hopping between slot, symmetrical at frequency band two ends.Generally, the physical resource of PUCCH channel is positioned at the two ends of up-link bandwidth, take the RB couple of some, as shown in Figure 2, for carrying the resource distribution of PUCCHformat2/2a/2b in the outside of up-link bandwidth, inwardly adjacent is successively the resource for carrying PUCCHformat1/1a/1b, high system level configuration parameter instruction is for carrying the RB of PUCCHformat2/2a/2b to quantity.Wherein, can configure mixedRB when system bandwidth is less, carry PUCCHformat1/1a/1b and PUCCHformat2/2a/2b at a pair RB to interior, as shown in Figure 3, mixing Physical Resource Block (mixedRB) is simultaneously corresponding RB couple.

The configuration instruction of eNB to the link PUCCH resource that direct transfers comprises following public high-rise configuration parameter: wherein, indicate RB for carrying PUCCHformat2/2a/2b to quantity, the namely original position of PUCCHformat1/1a/1b on frequency domain; refer to cyclic shift (cyclicshift) the sequence quantity for PUCCHformat1/1a/1b in mixedRB, when system configuration does not have mixedRB, refer to the relativity shift of the cyclically shifted sequences being used for PUCCHformat1/1a/1b; for the logic channel call number initial value of PUCCHformat1/1a/1b.Above-mentionedly configure relevant higher level parameters to PUCCH resource and indicate M-UE by system broadcast message or wireless heterogeneous networks (RRC, RadioResourceControl) message arrangement.

In LTE system, system broadcast message is the important sources that M-UE knows high system level control information, and the vital point that to be also eNB control/configure M-UE is to multicast communication configuration mode.

In LTE system, broadcast passes through the mapping relations of Broadcast Control Channel (BCCH, BroadcastControlChannel) as shown in Figure 4:

From the angle that system broadcast message sends, system information (SI, SystemInformation) is divided into following 3 parts:

$\mathrm{BCCH}\left\{\begin{array}{c}\mathrm{MIB}\\ \mathrm{SIB}1\\ \mathrm{otherSIBs}(e.g.:\mathrm{SIB}2,\mathrm{SIB}3......)\end{array}\right.$

MIB is mapped in broadcast channel (BCH, BroadcastChannel) on, be carried on Physical Broadcast Channel (PBCH again, PhysicalBroadcastChannel) on, system information block (SIB, SystemInformationBlock) SIBs is mapped on DSCH Downlink Shared Channel (DL-SCH, DownlinkSharedChannel), be carried on again on Physical Downlink Shared Channel (PDSCH, PhysicalDownlinkSharedCHannel).

In SI process of transmitting, SI sends with the form of SI message in its transmission window, except host system message block (MIB, MasterInformationBlock) other SIB and outside SIB1 will be mapped on SI and send, and the mapping relations of concrete SIB to SI will provide on SIB1.Concrete send mode sends according to following agreement:

MIB: to go forward 4 OFDM (OFDM) symbols at the slot1 of each radio frames subframe #0, frequency domain is on 6 RB (72 subcarriers) of centre, use fixing Quadrature Phase Shift Keying (QPSK, QuadraturePhaseShiftKeying) modulation system; The transmission of MIB is spaced apart 10ms, and 40ms changes and once launches the cycle as one.

SIB1: subframe #5 time domain being fixed on even number radio frames sends, dynamic dispatching on frequency domain.The transmission of SIB1 is spaced apart 20ms, and 80ms changes and once launches the cycle as one.

Other SIB (such as: SIB2, SIB3 etc.) except SIB: be mapped on corresponding SI, network side sends in units of SI message, UE side receives SI and obtains other corresponding SIB in corresponding SI window; In time domain in the SI window of correspondence, dynamic dispatching on frequency domain.

In LTE system, UE receives and the form with MIB, SIB1 and SI is obtained SI from eNB, and it can be used as the source of higher layer control messages important in this community.SI, as RRC information, will resolve at the rrc layer of UE and control function or the realization of associated sub-layer.With regard to sublayer citing, such as: radio link control (RLC, RadioLinkControl) sublayer, media interviews control (MAC, MediumAccessControl) sublayer

RRC information is transmitted between the chain of command rrc layer of eNB and UE,, a configurable one or more information element (IE in RRC information, informationelements), one or more IE item can be comprised further in IE, also can comprise and indicate the configuration of all kinds of parameter, identical IE item can be included in one or more RRC information and transmit.

In addition, according to the demand of Virtual network operator, also can be carried out the configuration instruction of parameter to the network equipment by OAM signaling, wherein, OAM signaling refers to operation (Operation), management (Administration), safeguards (Maintenance) related signaling.
