Disclosed are a downlink control information configuration and acquisition method, a base station and a terminal, wherein the base station configures a plurality of sets of receiving information for the terminal via a terminal specific high-layer signaling, and the base station indicates, to the terminal, which set in the plurality of sets of receiving information to use to perform a DMRS and/or physical downlink shared channel (PDSCH) reception by using at least one of the following information: a localized virtual resource block/distributed virtual resource block assignment (LVRB/DVRB) bit in the DCI Format 1A; a control channel mode where the DCI Format 1A is located, PDCCH and ePDCCH; an ePDCCH transmission mode where the DCI Format 1A is located, diversity transmission mode and localized transmission mode; and an ePDCCH cluster where the DCI Format 1A is located.

Downlink control information configuration and acquisition method, base station and terminal

A method for notifying a downlink demodulation pilot control signaling, includes: a base station side notifying a user equipment (UE) side of an index of a virtual signaling group and/or index of port offset signaling group used when generating a downlink pilot sequence and/or mapping the generated downlink pilot sequence through at least one of the following information: UE-specific or common high layer signaling; antenna indication information of DL_Grant; new data indication information in a Disable TB signaling in the DL_Grant; scrambling indication information in the DL_Grant; in a UE-specific or common search space, an aggregation level of the DL_Grant, a relative position of a first control channel element of the DL_Grant in the UE-specific or common search space, a subframe number where the DL_Grant is located and a system frame number where the DL_Grant is located.

Method, base station, and terminal for notifying and receiving downlink demodulation pilot frequency control signaling

The disclosure discloses a method and system for processing control channel information. A receiving side is notified, by a network side via one or more types of the following signaling, of the information required to receive or perform blind detection for a control channel, wherein the signaling part comprises at least: a Radio Resource Control (RRC) signaling, a System Information Block (SIB)x (x=2, 3) signaling, and a Physical Downlink Control Channel (PDCCH) signaling located at the first n (n=1, 2, 3, 4) Orthogonal Frequency-Division Multiplexing (OFDM) symbols. In the control channel information processing technology of the disclosure, the receiving side can be notified, via signaling configuration, of at least the time domain or frequency domain location occupied by the control channel. This scheme allows for full utilization of space division technology, thus reducing the load on a physical downlink control channel, and reducing interference between control channels.

Method and system for processing control channel information

The present invention discloses a method for determining a radio frame bearing a multimedia broadcast multicast service notification message, including: a sending end configuring a Multicast Control Channel (MCCH) Modification Period (MCCHMP), a period coefficient (PeriodCoeff) and a notification message offset (NotificationOffset), and when a system frame number (SFN) modulo a ratio of the MCCHMP to the PeriodCoeff is equal to the NotificationOffset, a radio frame corresponding to a value of said SFN is the radio frame of sending the Multimedia Broadcast Multicast Service (MBMS) notification message. The present invention obtains the radio frame of sending the MBMS notification message by less MCCH information, so that the receiving and analyzing processes of the terminal save power.

Method for determining wireless frame bearing multimedia broadcast multicast service notification information and transmitter thereof

A method and device for realizing smart antenna in WCDMA system are disclosed in the invention, including array antenna, radio frequency channel module, beam forming module, channel environment detection and classification module, beam-forming algorithm selection and weight value generation module. After processing the signals received by the antenna array in RF channel, the baseband array data X including multiple components is obtained, then the channel environment is estimated and identified according to the characteristics of said array data, and the channel type which the channel belongs to is determined; the corresponding adaptive beam forming algorithm is selected according to the identification result of the channel type, so as to calculate the uplink weight value W including multiple components; said array data X and weight value W are multiplied so as to form beam Y. The invention can adopt corresponding adaptive beam forming algorithm based on the channel environments, thus it can effectively restrain the interference under various channel environments.
