ethod and apparatus for controlling multi-antenna transmission in wireless communication network // 2474048
FIELD: information technology.SUBSTANCE: multi-antenna transmission control presented herein involves generating a set of virtual channel realisations in a transmitter (10) which shares the same second-order statistics as the actual channel realisations observed for a targeted receiver (12). By making the control-related quantities of interest at the transmitter (10) depend on the long-term statistics of the channel, the actual channel realisations are not needed for transmission control, e.g., for accurate multiple-input/multiple-output (MIMO) precoding and the related modulation and coding choice.EFFECT: use of virtual channel realisations enables transmission control which approaches the closed-loop channel capacity which would be provided by full feedback of the channel status information without requiring the overhead signalling burden which accompanies full feedback.17 cl, 4 dwg

Beam control and beam generation for wideband mimo/miso systems // 2463707
FIELD: radio engineering.SUBSTANCE: invention may be used to send data in communication systems with multiple inputs and multiple outputs or with multiple inputs and one output (MIMO/MISO). The method to process data for transfer along a wideband multi-input channel consists in receiving a control vector for each of multiple subranges, at the same time each control vector comprises multiple elements for multiple transmitting antennas, and in preliminary conversion of modulation symbols to be transferred in each subrange, using a control vector for a subrange, besides, the control vector for each subrange is received on the basis of its own vector corresponding to its main mode.EFFECT: improvement of working indices under unfavourable channel conditions.19 cl, 5 dwg

Setting maximum power in mobile communication system base station having multiple antennae // 2460216
FIELD: information technology.SUBSTANCE: MIMO-capable base station allocates a maximum transmission power resource to each of its antennae. For serving each of one or more MIMO and non-MIMO users, one or more carriers are allocated. For each carrier, information about the amount of allocated MIMO and non-MIMO user resources associated with the carrier is used to derive coefficients. For each carrier, the coefficients and the maximum transmission power resource for the carrier are used to derive a maximum transmission power resource for each of the antennae. For each antenna, a total maximum transmission power resource is derived. If it is determined that the total maximum transmission power resource of the antenna exceeds the transmission power limit for the antenna, and radio conditions for a non-MIMO user satisfy one or more predefined criteria, then one of the secondary antennae of the carrier is used to serve the non-MIMO user.EFFECT: efficient use of transmission power of a base station.16 cl, 5 dwg, 2 tbl

Feedback of channel state information for mimo and subband scheduling in wireless communication system // 2457621
FIELD: information technology.SUBSTANCE: techniques for efficiently sending channel state information using differential encoding are described. Differential encoding may be performed across space, across frequency, across space and frequency, across space, frequency and time, or across some other combination of dimensions. In one design, spatial state information may be determined for multiple spatial channels on multiple subbands. The spatial channels may correspond to different antennae, different precoding vectors, etc. Channel quality indicator (CQI) values may be obtained for the multiple spatial channels on the multiple subbands. The CQI values may be differentially encoded across the multiple spatial channels and the multiple subbands to obtain differential CQI information. In another design, CQI values may be obtained for multiple spatial channels on the multiple subbands in multiple time intervals and may be differentially encoded across space, frequency and time. The differential CQI information and the spatial state information may be sent as feedback.EFFECT: efficient transmission of channel state information in a wireless communication system.51 cl, 16 dwg
