Hereafter to the present embodiments relate to nonstandard bandwidth be introduced.
LTE defines the standard bandwidth of 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and 20MHz.For nonstandard bandwidth, it can realize by way of reducing the effective bandwidth of standard bandwidth, can both make full use of frequency resource and not influence existing terminal.
The technology for reducing effective bandwidth is actual available bandwidth to be configured to standard bandwidth use, and standard bandwidth is carried out some limitations and compression processing, allows in standard bandwidth and transmits the bandwidth of data within the scope of actual available bandwidth.The applicable range of this scheme is wider.
As shown in table 1, different bandwidth accommodates different RB (Resource Block, resource block) number.The method for reducing standard bandwidth effective bandwidth includes compression RB number and channel specially treated.By taking the nonstandard bandwidth for realizing 8MHz as an example, the standard bandwidth for accommodating the 10MHz of 50 RB can be compressed to 40 RB by compressing 10 RB to realize the nonstandard bandwidth of 8MHz by base station.
1 bandwidth of table and its RB number can be accommodated
Bandwidth (MHz) 1.4 3 5 8 9 10 15 19 20
RB number can be accommodated 6 15 25 40 46 50 75 98 100
It is transparent to terminal to compress RB.By compression standard bandwidth with obtained nonstandard bandwidth under, in order to reduce the performance loss that compression RB is generated, base station will be adjusted the Resource Management Algorithm of related physical channel, guarantee not distribute resource in the position RB of compression.Relevant physical channel is as described below.
Uplink physical channel:

PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) guarantees that distribution resource is not take up the RB of compression by scheduling.
SRS (Sounding Reference Signal, Sounding Reference Signal) only uses available RB, and resource distribution mode is constant.
Down physical channel:
PCFICH (Physical Control Format Indicator Channel, Physical Control Format Indicator Channel), the distribution of limitation PCI (Protocol Control Information, Protocol Control Information) guarantees that PCFICH is not take up the subcarrier on the RB of compression.
PHICH (Physical Hybrid ARQ Indicator Channel, physical mixed automatic re-transmission indicating channel) limits the Ng parameter of PCI distribution and PHICH, guarantees that PHICH is not take up the subcarrier on the RB of compression.
PDCCH:physical downlink control channel, Physical Downlink Control Channel, the CCE of certain UE, Control Channel Element control channel unit can be mapped on compression RB, need to improve PDCCH demodulation performance.
PDSCH:Physical Downlink Shared Channel-- Physical Downlink Shared Channel needs to limit the RB resource that do not dispatch on compression bandwidth.
Hereafter to the present embodiments relate to eMBMS related notion be introduced.
For eMBMS using point-to-multipoint unidirectionally lower line mode, the cell under base station distributes a sharable broadcasting service bearing resource, can provide business transmission to multiple terminals simultaneously.The characteristic of eMBMS is broadcasted using multi-plot joint, point-to-multipoint transmission mode, the data of control plane and user face are transmitted by public broadcast channel, for the same interested terminal of eMBMS business under cell, can be received on identical radio resource and shared with portion eMBMS business datum.Have the terminal that eMBMS business receives ability, supports to carry out the reception of eMBMS business datum in connected state or Idle state, and the reception of eMBMS business should not be influenced by whether terminal carries out unicast service simultaneously.Do not have the terminal that eMBMS business receives ability, it needs according to SIB2 (System Information Block Type 2, System information block 2) message content identification MBSFN sub-frame configuration information, MBSFN (networking of MBMS Single Frequency Network, MBMS single-frequency point) subframe is avoided in downlink measurement.
Cell in one synchronization zone MBSFN corresponds to identical frequency point；The corresponding synchronization zone MBSFN of the cell of identical frequency point in one base station.May exist multiple MA (MBSFN Area, MBMS single-frequency point group web area) under one synchronization zone MBSFN.There are MBSFN cell and MA to retain below one MA Two kinds of cells of cell.All MBSFN cells and MA below one MA, which retain cell, should have completely the same MBSFN radio resource allocation strategy.One cell may belong to multiple MA, i.e. MA can be overlapped.Be between MA and MBMS service area it is independent, without positive connection.But in order to which maximum resource utilization and plan of operation safeguard convenience, in MBMS business planning, it is desirable that plan one or more complete MA under a MBMS service area.
