摘要： A method, in a network node, for transmitting data in a heterogeneous network cellular communication system comprises transmitting of a SFN pilot signal (262). A SFN pilot signal is a pilot signal transmitted by all radio units of a heterogeneous network cell. Optionally, configuration information about non-SFN pilot signals in a cell of the network node is transmitted (260). Non-SFN pilot signals are pilot signals transmitted by less than all radio units of a heterogeneous network cell. The non-SFN pilot signal is transmitted (264). A control channel signal is transmitted (270) on a control channel and a data channel signal associated with the transmitted control channel signal is transmitted (280) on a data channel. A network node operable therefore is also presented. A method for receiving data in a heterogeneous network cellular communication system and a wireless device operable therefore are also presented.

摘要： One aspect of the present invention concerns the management of processing resource allocations for a Turbo receiver, where such resources are consumed from a finite resource budget within a defined processing time interval. The contemplated Turbo receiver attempts to allocate more processing resources to those demodulation and/or Turbo decoding tasks that make more valuable contributions with respect to the ultimate goal of successfully decoding all data streams that are of interest in a received signal. The advantageous management approach allows the Turbo receiver to obtain better results for a given consumption of processing resources, and further permits the Turbo receiver to quit upon either achieving a successful outcome within a defined processing time interval or exhausting the budgeted resources.

摘要： A system and method in which a base station (34) treats the Channel State Information, CSJ. from wireless terminals (28, 29) as only partially- stale, and exploits this partially-stale CSi to predict the current channel from old estimates of the channel. The predicted channel is then used to design a precoder (60). The base station shapes the transmitted signal with the precoder so as to match it as closely as possible to the current channel. Particular embodiments of the disclosed solutions thus combine the benefits of the stale feedback scheme with preceding to match the channel. As a result, the signal received at a terminal (28, 29) is better conditioned, thereby providing a greater overall boost ra performance of the communication arrangement between the base station (34) and the terminal (28, 29). The usage of partially-stale CSI can be important for dense networks with a large number of simple terminals.

摘要： Channel quality metrics (such as SINR, BLER, and the like) are derived from a raw bit error rate (RBER), defined as the error rate of raw bits output by a demodulator. These initial raw bits are decoded and error-checked (or error-corrected). The error-free decoded bits are re-encoded, and the regenerated raw bits are compared to the initial raw bits to determine the RBER. The RBER is then converted to SINR, BLER, or other channel quality metric. The RBER-based metrics are derived from a data channel rather than reference signals, and hence more accurately reflect deviations from nominal transmission power level, and include receiver demodulator impairments.

摘要： A method and apparatus provide advantageous uplink power control for a set of uplink channels transmitted by a mobile terminal or other item of user equipment (UE). The proposed uplink power control maintains the total received power for the set of uplink channels at or about a target received power, while also maintaining the received signal quality for a subset of those channels---e.g, a particular one of them---at or about a target received signal qualify. In an advantageous but non-limiting example embodiment, the subset comprises a fixed-rate control channel, and the set includes that control channel and a variable-rate traffic channel Correspondingly, a base station generates first power control commands to maintain the received signal quality of the control channel at or about some quality target, and generates second power control commands to maintain the total received power (of the two channels) at or about some power target.

摘要： A pilot channel signal for time-division multiplexing with one or more traffic channel signals in a broadcast/multi-cast signal and for code-division multiplexing with a continuously transmitted pilot channel signal is described. In an exemplary method for transmitting a broadcast/multicast signal, a pilot symbol sequence is obtained for each slot of one or more frames of the broadcast/multicast signal, so that the pilot symbol sequence varies for each slot of a given frame. The pilot symbol sequence for each slot is spread with a channelization code, and the spread pilot symbol sequence for each slot is scrambled, using a scrambling code, to form a first pilot channel signal. The first pilot channel signal is transmitted so that it is time-division multiplexed with one or more traffic channel signals transmitted during each slot and code-division multiplexed with a second pilot channel signal transmitted during all slots of the one or more frames.

摘要： There is provided a method,and corresponding nodes,of enabling adjustment of the transmit power of a User Equipment, UE, in a wireless network. The method comprises the step (S10) of generating an individual gain factor for at least one specific channel, determining (S20) a dynamic gain factor command corresponding to the individual gain factor and sending (S30) the dynamic gain factor command to the UE to enable the UE to increase or boost the transmit power for communications on the at least one specific channel without increasing transmit power on other channels.

摘要： According to the teachings presented herein, 'spreading code' knowledge is used in forming amplitude references for QAM demodulation in a DS-CDMA receiver. Here, 'spreading code' broadly refers to spreading/channelization codes, scrambling codes, or the product of such codes. Further, these teachings apply to any linear DS-CDMA demodulator, such as Rake, Generalized Rake (G-Rake), or chip equalizer, and to nonlinear demodulators that employ linear filtering, such as decision feedback equalizers (DFEs). Advantageously, the determination of symbol-specific amplitude references relies on shared correlation estimates and/or shared combining weights that are common to two or more symbols of interest, thereby significantly reducing processing requirements as compared to the use of symbol-specific impairment correlation estimates.

摘要： Methods and apparatus are disclosed for suppressing both own-cell and other-cell interference in the processing of multiple signals of interest in a received composite signal. In an exemplary embodiment of the methods disclosed herein, combining weights for each of a first plurality of signals of interest in a composite information signal are computed (320), based on first shared signal correlation data computed (310) from the composite information signal. A reduced-interference composite signal is calculated (330) from the composite information signal, using, for instance, subtractive interference cancellation or interference projection techniques. Combining weights for processing each of a second plurality of signals of interest are computed (350) as a function of second shared signal correlation data corresponding to the reduced- interference composite signal. Corresponding apparatus, including G-Rake (50) and chip equalizer (60) embodiments are also disclosed.
