Description
Technical field
The present invention relates to communication technique field, more particularly to a kind of method for adjusting physical downlink control channel polymerization
And device.
Background technology
In 3GPP LTE (Long Term Evolution, Long Term Evolution) system, base station is according to UE (User
Equipment, user terminal) transmission mode, and transmission plan gives user's selection to send various DCI (Downlink
Control Information, Downlink Control Information) Format Type, it is carried on PDCCH (physical downlink
Control channel, Physical Downlink Control Channel) in be transmitted.
In the LTE 10ms defined frame structure, one TTI (Transmission Time of 1ms descending sub frames correspondence
Interval, Transmission Time Interval) in, PDCCH only takes up time domain and gone forward n OFDM (Orthogonal Frequency
Division Multiplexing, orthogonal frequency division multiplexi) symbol, the remaining frequency after remaining channel occupancy is removed on frequency domain
Band, wherein mainly including reference signal, PCFICH (Physical Control Format Indicator Channel, physics
Format indication channel), PHICH (Physical HARQ Indicator Channel, Physical HARQ Indicator Channel;Wherein,
HARQ is:Hybrid Automatic Repeat Request, hybrid automatic repeat-request) etc..Therefore row subframe in each of the lower
Interior, only the reserved running time-frequency resource of limited quantity can be used for transmission Downlink Control Information, and this part is referred to as into control domain.
The least unit of PDCCH time-frequency resource allocatings is CCE (Control Channel Element, control channel money
Source), a CCE includes 9 REG (Resource Element Group, resource unit group), i.e., 36 RE (Resource
Element, resource unit).PDCCH uses QPSK (Quadrature Phase Shift Keying, quadrature phase shift key
Control), in order to provide different reliabilities by code rate, it is allowed to which CCE has four kinds of degree of polymerization, respectively 1,2,4,8.
Prior art discloses a kind of method for determining number of channel control blocks, specific as follows:According to CQI (Channel
Quality Indicator, CQI) information, determine in a radio frames what each optional PDCCH can be carried
Maximum number bits;The maximum number bits that can be carried according to each PDCCH of determination, and be currently needed for the control signaling of transmission
Data volume, it is determined that each PDCCH mass parameter;By mass parameter maximum in all PDCCH of determination mass parameter with
Threshold value is compared, and a PDCCH is selected in all optional PDCCH from a radio frames according to comparative result, and really
Determine the corresponding control channel numbers of blocks of PDCCH of selection.
A kind of method of PDCCH resource distribution is also disclosed in the prior art, it is specific as follows:It is multiple to divide PDCCH resource
Control channel unit CCE collection;Integrated according to multiple CCE as the main CCE collection of cell configuration and auxiliary CCE collection;Main CCE collection resource is distributed to
