Description

A kind of method and device transmitting pilot configuration information
Technical field
The present invention relates to the communications field, particularly relate to transmit the method and device of pilot configuration information.
Background technology
In communication process, the demodulation to channel is requisite link.Generally use the pilot tone received Carry out demodulated channel.Before receiving pilot tone, need to be known a priori by the port numbers of pilot tone and port number, in order to Pilot tone is received in corresponding position.Pilot tone includes public guide frequency (such as cell common reference signal (CRS)) With dedicated pilot (such as demodulated reference signal (DMRS)).
When pilot tone is CRS, the port number of CRS can obtain by receiving broadcast message.In community All trunkings and subscriber equipment (UE) all use identical pilot tone to carry out channel demodulation, and problem is nothing Method is individually for certain equipment configuration CRS.
When pilot tone is DMRS, owing to DMRS is only used for the demodulation of data channel, therefore its port Number and port number can not transmit in broadcast channel, be currently at Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) control information format in transmit.But, base station (as Evolution base station (eNB)) while trunking transmission PDCCH, trunking is also to subscriber equipment Transmission PDCCH, therefore trunking cannot receive the PDCCH of base station transmission, the most just cannot be from PDCCH Middle acquisition port information demodulates the Physical Downlink Control Channel (R-PDCCH) etc. of relaying.
To sum up, the most not yet the port information of vaild notice DMRS is to the scheme of trunking, in causing The equipment of continuing cannot receive DMRS and the demodulation of follow-up channel.And, it is impossible to it is embodied as equipment and is separately configured CRS。

Detailed description of the invention
In the embodiment of the present invention, the pilot configuration information configured for R-PDCCH is sent out by base station by high-level signaling Give trunking, make via node can receive pilot tone according to pilot configuration information and R-PDCCH is entered Row channel demodulates.Pilot configuration information includes pilot type information and pilot frequency port information, it is also possible to include Other information relevant with pilot tone.Pilot type information includes public guide frequency type information or dedicated pilot class At least one in type information.Pilot frequency port information includes the pilot frequency port information for R-PDCCH configuration With at least one in pilot frequency port information of number.Broadcast channel or dedicated channel are passed through by described height in base station Layer signaling is sent to trunking.High-level signaling such as wireless heterogeneous networks (RRC) etc..Therefore, the present invention Embodiment had both solved the port information that cannot notify DMRS to the problem of trunking, solved again nothing Method is embodied as the problem that equipment is separately configured CRS.
Seeing Fig. 1, the relay system in the present embodiment includes base station and trunking.
Base station is the most mutual with trunking and subscriber equipment, it is also possible to be directly connected with core net (CN). Base station is for generating the pilot type information included for R-PDCCH configuration, and includes for R-PDCCH The pilot frequency port information of configuration and/or the high-level signaling of pilot frequency port information of number, and by described high-rise letter Order is sent to trunking.
Trunking, for forwarding the message between subscriber equipment and base station, receives the high-rise letter that base station sends Order, and parse the pilot type information into R-PDCCH configuration, and include configuring for R-PDCCH Pilot frequency port information and/or pilot frequency port information of number, and according to the pilot tone configured for R-PDCCH Type information, and for R-PDCCH configuration pilot frequency port information and/or pilot frequency port information of number Receive pilot tone.
Wherein, pilot type information has multiple concrete manifestation form, as realized by type identification, different Type identification represent public guide frequency and dedicated pilot.Or, represent special with a type identification and lead Frequently, when high-level signaling carries the type mark, the pilot configuration information of instruction dedicated pilot, if not Carry the type mark, it indicates that the pilot configuration information of public guide frequency.Can be there to be other form, this Place does not enumerates.
High-level signaling can include pilot frequency port information and/or pilot frequency port information of number.Such as, high-rise Signaling can only include pilot frequency port information, and the whole port numbers configured for R-PDCCH are carried by base station In high-level signaling, the program can be that R-PDCCH configures discontinuous port numbers.High-level signaling can be only Including pilot frequency port information of number, pilot frequency port information of number can be the coding of concrete numeral or numeral Deng, the program needs to prenotice trunking and initiates pilot frequency port number, can be notified by high-level signaling Can also be configured for trunking by Operation and Maintenance entity etc., then high-level signaling is passed through by pilot tone in base station Port number information notifies that trunking is according to initial pilot frequency port number and pilot frequency port number to trunking Mesh information determines pilot frequency port number, and if initial pilot frequency port number is 7, pilot frequency port information of number is 2, then Pilot frequency port number for R-PDCCH configuration is 7 and 8.The program is primarily adapted for use in configuration continuous print pilot tone Port numbers, and relative to only including the mode of pilot frequency port information, Signalling length can be saved.High-rise When signaling includes pilot frequency port information and pilot frequency port information of number, pilot frequency port information can be Beginning pilot frequency port number, trunking determines pilot tone according to initial pilot frequency port number and pilot frequency port information of number Port numbers, which is relative to the mode only carrying pilot frequency port information of number, it may not be necessary to fixes and joins Put initial pilot frequency port number, different initial pilot frequency port number can be specified during configuration every time.And joining When the pilot frequency port number put is more, more save signaling money relative to the mode only carrying pilot frequency port information Source.If being pre-configured with the corresponding relation of initial pilot frequency port number and pilot type information, such as public guide frequency Initial pilot frequency port number be 0, the initial pilot frequency port number of dedicated pilot is 7, then can be at high-level signaling Middle omission pilot type information, is represented by pilot frequency port embodying information.If fixed configurations pilot frequency port number Mesh information and the corresponding relation being pre-configured with initial pilot frequency port number and pilot type information, the most only by height Floor signals pilot type information also can imply expression pilot frequency port information and pilot frequency port information of number. To sum up, high-level signaling can only carry pilot type information, or only carries pilot frequency port information, or Carry pilot type information and pilot frequency port information of number, or carry pilot frequency port information and pilot frequency port Information of number, or carry pilot type information, pilot frequency port information and pilot frequency port information of number.
