Description
Technical field
The present invention relates to the communications fields, in particular to a kind of public reference signal CRS information processing methods and dress
It sets.
Background technology
Long term evolution(Long Term Evolution, abbreviation LTE)System is after it experienced the several versions of R8/9/10, again
R11 technologies are accurately studied successively.R8 the and R9 stages are being experienced, R10 increases many new spies again on the basis of the above two
Property, for example, demodulated reference signal(Demodulation Reference Signal, referred to as DMRS), channel state information ginseng
The pilot tones characteristics such as signal (Channel State Information Reference Signal, CSI-RS) are examined, 8 antennas are supported
Enhancing is offset Deng transmission and feedback characteristics etc., especially inter-cell interference(ehanced Inter-Cell Interference
Cancellin, referred to as eICIC)Technology further considers the interference between cell on the basis for considering R8/9ICIC
Avoid technology.It is dry for cell of the technology in the case where R10 initial stages in stage mainly consider homogenous networks for solving interference problem between cell
Disturb and avoid, wherein mainstream the considerations of eICIC technologies and multipoint cooperative(Coordinated Multi-point, referred to as CoMP)
Technology.
Exactly multiple nodes cooperate to one or more UE in identical running time-frequency resource or difference CoMP as its name suggests
Running time-frequency resource carry out transmission data.Technology can reduce the interference between cell in this way, improve the throughput of cell edge, expand
MPS process.But due to discussing that the later stage considers heterogeneous network and introduces more scenes, the complexity and R10 of CoMP technologies
The time restriction of discussion, it is final to determine not introducing additional CoMP standardized contents in the R10 stages, but can designing CSI-RS
Designed with considering the demand of the parts CoMP, thus CoMP technologies after 60bis meetings with regard to without carrying out further discussion.
LTE defines Physical Downlink Control Channel(Physical downlink control channel, referred to as
PDCCH)Dispatching distribution and other control information are carried, each PDCCH is by several control channel units(Control
Channel Element, CCE)Composition, the CCE numbers of each subframe are determined by the quantity and downlink bandwidth of PDCCH.
UE by search space blind Detecting obtain PDCCH, search space is divided into public search space and UE is special searches
Rope space, public search space refer to the region that all UE can be searched, and what this space carried is cell Proprietary Information.Specially
It is the spatial dimension that single UE can be searched with search space, the dedicated search space of multiple UE is possible to be overlapped, only generally
Initial searching position is different.Before blind examination, UE operating modes are notified by high-level signaling and for the CRC (Cyclic of PDCCH
Redundancy Check, cyclic redundancy check) scrambled radio network temporary identifier (Radio Network Temporary
Identity, referred to as RNTI) type.
Table 1 is search spaceWith aggregation level L and candidate's PDCCH quantity M(L)Between relation table, as shown in table 1.It is poly-
Close the CCE number that grade, that is, PDCCH is occupied.User's dedicated search space carry out blind Detecting when, user equipment first according to
Mark (UE ID) and subframe numbers etc. calculate blind examination initial position Y at familyk, then it is detected in search space, until detection
Until the PDCCH for giving oneself.
Table 1
Table 2 is relative position of the first control channel unit of aggregation level and PDCCH in user's dedicated search space
Mapping table.Relative position of the first control channel unit of PDCCH in user's dedicated search space refers to PDCCH occupancy
First CCE indexes nCCE and blind examination initial position YkRelative position, herein use nCCE, offset indicate, nCCE,
offset=nCCE-Yk, the value range of nCCE, offset are 0 ~ 6,8,10.As shown in table 2, it is UE dedicated search space, it can
First position CCE of energy and its relation table of corresponding polymerization grade.
