Description

Beam guiding method, and inter-beam cooperative transmission method and device

Technical Field

The present invention relates to the field of radio communications, and in particular, to a beam steering method, and an inter-beam cooperative transmission method and apparatus.

Background

The realization of fast migration of terminal communication links among cells through cooperative transmission among cells is a demand for the subsequent evolution of an lte (long term evolution) system. The proposed coordinated multipoint transmission in the LTE system is to improve the transmission rate of the cell edge terminal, and specifically to improve the received signal strength of the terminal in the edge area. The implementation of coordinated multipoint transmission (CoMP) is based on inter-cell interference coordination, which is a transmission diversity or MIMO transmission scheme that must be implemented when the inter-multipoint interference is avoided.

CS/cb (coordinated scheduling and beamforming) is an inter-beam coordination technique that can dynamically reduce interference from other cells. The data of the UE can be obtained from the service node, and the scheduling and beam forming of the user are based on the coordination result between eNodeBs in the CoMP cluster.

The core technology of downlink CoMP is JPT (joint processing and transmission), and JPT includes two implementation manners:

dynamic node selection, according to CSI information, dynamically selecting one eNodeB from a cluster of eNodeBs participating in cooperative transmission for sending data to UE;

joint sending, according to the CSI information, dynamically selecting two or more eNodeBs from a cluster of eNodeBs participating in cooperative transmission to simultaneously send data to the UE;

for multiple enodebs simultaneously used to transmit data to a UE, two cases are possible: non-coherent transmission, typically in transmit diversity, and coherent transmission, typically in MIMO transmission.

From the view of the link control mode of CoMP, one is a respective control mode of each cell/node adopted by the existing CoMP transmission in the LTE system, and is characterized in that: in coordinated multipoint transmission (CoMP), a control instruction sent by each wireless node/cell participating in coordinated multipoint transmission is only used for controlling data transmission between the cell and a terminal, and does not control data transmission between the terminal and other nodes participating in coordinated multipoint transmission, and the control instruction adopted by the existing CoMP is essentially based on a traditional control instruction of transmission/single stream transmission of the cell; the other is the patent with application number 200910203029.9, the name of the invention is: one node in a group of nodes participating in CoMP is used as a control node, and the control node sends a scheduling instruction to control data transmission of other nodes participating in COPM transmission.

During soft handoff, the mobile station searches all pilot signals to detect existing CDMA channels and measure their strengths. When the mobile station detects that the Pilot signal Strength of the adjacent Pilot signal set or the remaining Pilot signal sets exceeds T _ ADD, it sends a Pilot Strength Measurement Message (PSMM) to the serving base station.

The service base station sends the report to the MSC, the MSC informs the switching destination base station to arrange a forward service channel to the mobile station, the forward service channels of the two base stations send the same modulation symbols except the power control sub-channel, and the service base station sends a switching indication Message (HDM) containing the PN number, the forward service channel number, the switching parameters and the like of the switching destination base station to indicate the mobile station to start switching.

The mobile station adds the PN of the switching target base station into an effective pilot frequency set according to the received switching indication message, and demodulates the forward service channels of the two base stations. After the demodulation is completed, a Handover Complete Message (HCM) is transmitted.

As the mobile station moves, the mobile station starts a handoff DROP timer T _ TDROP when one of the pilot signal strengths of the active set is below T _ DROP. When the timer T _ TDROP expires, it sends a PSMM to both base stations.

After receiving PSMM, two base stations send the message to MSC, MSC returns corresponding HDM, base station forwards to mobile station, mobile station moves the pilot signal out of active set according to switching indication message, and sends HCM.

Although the soft handover realizes the migration process of the terminal between the wireless nodes after the terminal is connected and then disconnected between the cells with the same frequency, the time consumption of the soft handover of the terminal is large, only the measurement process of a physical layer takes 200 milliseconds, in addition, the diversity connection of the service channels of two adjacent base stations and the terminal is not always necessary, and the diversity connection limits the flexibility of configuring the time-frequency resource of the service channel for the migrated terminal between the adjacent base stations.

In the prior art of Searching and Tracking targets by radars, a Tracking While Scanning (TWS) radar is a radar which continuously tracks targets and must continuously scan and search a space.

Advanced fire control or police radar generally adopts a multifunctional module to execute various tactical tasks, and can implement searching in a multi-target environment and also can implement tracking in the multi-target environment. The number of targets is different, the number of working modes is different, the radar frame periods are different, for an airborne radar, in order to guarantee detection of targets above the horizon, the frame period is 10 seconds, and when the frame period exceeds 10 seconds, the targets are not reported.

The patent number US54720711 entitled "beam-jump track-while-scan radar system" (Agile-beam-scan radar system) discloses a radar with tracking dwell and search dwell, which operates as follows: emitting an illumination signal tracking the dwell and searching for the dwell during the dwell period; receiving echo signals from the illuminated target; configuring a predetermined number of tracking dwell intervals within a dwell period; determining the acceleration of a target transmitting an echo signal; the priority of the target is divided according to the acceleration of the target; updating the irradiation frequency of different levels of the target in a dwell period; a search dwell time is inserted within the tracking interval.

In summary, the prior art has the following disadvantages: under the condition that no signaling is directly connected between the wireless access point and the terminal, the relative azimuth information and the channel state between the wireless access point and the terminal cannot be quickly acquired, and the potential cooperative transmission relationship between the beams of the wireless access point and the adjacent wireless access points cannot be determined in real time.
