The present invention discloses a method for compensating when part of channels in the intelligent antenna system lapses. The invention aims at the problem that the downward beam shaping capacity of the intelligent antennae will dramatically decline when a certain or a plurality of channels in the intelligent antenna system lapse. The compensating method of the invention in the intelligent antenna system when part channels lapse comprises the steps of: (1) obtaining the number of the disabled ascending descending channels, the disabled channel number and the lapse style; (2) sharing equally the business of all the user covered by the intelligent antenna system to each effective descending antenna to transmit if the lapse style is that the shaping antenna of the special channel is damaged;and choosing the channel with the maximal transmitting power in the effective descending channel or adapting the common signal channel to compensate the weight by the descending beam shaping weight if the lapse style is that the shaping antenna of the common signal channel is damaged. The invention perfects the covering of the intelligent antenna system to the small district and increases the capacity of the small district and the speech quality of the user.

The invention discloses a method, a device and equipment for determining a data transmission mode, which relate to communication technology and can save the power consumption of a terminal at the same time of increasing the capacity of a cell. The method for determining the data transmission mode provided by the embodiment of the invention comprises that: an access network determines the working mode of HS-SCCH less operation needing configuring to the terminal according to the acquired service type of the terminal; and the access network informs the terminal of the determined working mode of the HS-SCCH less operation needing configuring to the terminal, wherein the working mode comprises the mode of supporting or not supporting the HS-SCCH less operation.

The present invention discloses an uplink power control method, which is suitable for WCDMA systems. The method includes: after receiving the first subframe of a wireless frame, the base station uses the first subframe to estimate the signal-to-noise ratio (SIR); if the first subframe If the SIR estimation result of the frame does not exceed the preset threshold, then the target signal-to-noise ratio (SIRtarget) of the user terminal is reduced in subframes following the transmission time interval TTI. Thereby reducing the transmit power of the HSUPA user terminal. The invention also discloses an uplink power control device, a base station and a system. Through the invention, the transmission power of the HSUPA user terminal can be effectively reduced, the uplink interference can be reduced, and system performance and capacity can be improved.

The invention provides a method and a device for pre-coding matrix / vector in a multi-input and multi-output system. The method comprises the steps as follows: a data receiving terminal selects the pre-coding matrix index or the pre-coding vector index of a user by judging whether every data stream of the user transferred is retransmission data stream or not. After the condition that the user retransmission is needed or not is considered, pre-coding index information fed back by the user in a multi-input and multi-output pre-coding system is selected, thereby the throughput of the system is further enhanced.

The invention discloses a method and a device for receiving information by high speed shared information channels (HS-SICH), which are used for improving the utilization rate of HS-SICH resources and the signal receiving quality of the HS-SICH. The method for receiving the information by the HS-SICHs comprises that: a base station allocates an identical high speed shared control channel (HS-SCCH)for each user equipment in each group obtained by grouping according to space division multiple access (SDMA) pairing grouping conditions, and allocates a plurality of different HS-SICHs for the userequipment in the group; and for the user equipment in each group, the base station indicates the user equipment in the group by the HS-SCCHs allocated for the user equipment to transmit the information to the base station by adopting the HS-SICHs allocated for the user equipment, and simultaneously receives the information from the user equipment in the group by the plurality of different HS-SICHs.

The invention relates to a method for receiving a long scrambling code of a downstream cluster service in a time division duplex communication system, which comprises the steps as follows: a base station broadcasts and transmits system data information with the long scrambling code to a target user group in the cell; user equipment estimates channel impulse responses for training sequences in the cell and in the neighboring cells according to the received system data information to obtain the channel impulse responses corresponding to each cell; the power of the channel impulse responses of each cell is estimated to obtain the power of the channel impulse responses corresponding to each cell, and the power of the channel impulse responses is sorted to determine the cells with effective receptions; and the rake reception and interference elimination, demodulation and decoding process are carried out cell by cell to the cells with effective receptions so as to obtain expected user data. Based on the method, the invention also provides a receiver-transmitter unit for realizing the method. The invention effectively overcomes the multi-cell interference, so as to improve the transmission performance of the cluster mass-sending service and the cell capacity.
