Abstract: A network node that serves a host cell in a cellular communication system transmits, at (a) first time interval(s), first control channel information on a control channel that extends over a first bandwidth of a radiofrequency spectrum. The first control channel communicates information necessary to enable a first type of communication device to receive data from the host cell. The first type of communication device can receive first bandwidth-wide signals. At (a) second time interval(s), second control channel information is transmitted on a second control channel of a first M-cell. The second control channel occupies a second bandwidth that is smaller than the first bandwidth. The second time interval(s) do(es) not coincide with any of the first time interval(s). A second type of communication device having reduced receive bandwidth capabilities compared to those of the first type of communication device is thereby made capable of being served by the node.

Abstract: Methods and apparatus are disclosed for transmitting data to a remote node via each of two or mote transmitted earner signals, wherein a distinct outbound packet data traffic channel is mapped to each transmitted carrier signal. In an exemplary method, aggregated control channel data is formed by combining control channel data corresponding to each of two or more received carrier signals, simultaneously transmitting traffic channel data to the remote node on each of the two o or more outbound packet data traffic channels, and transmitting the aggregated control channel data using one or more physical control channels mapped to a first one of the transmitted carrier signals. In particular, these methods and apparatus may be applied to a multi-carrier High-Speed Packet Access (HSPA) system.

Abstract: A receiver (20) for use in wireless communications with plural transmitters (22) comprises transmitter selection logic (34); a signal estimator (36): and an image estimator (38). The image estimator (38) is configured to form an estimate of an image signal occurring on the second sub-carrier and attributable to a transmission of the first transmitter. The signal estimator (36) is configured, e.g., to use the estimate of the image signal and a signal received on the second sub-carrier to obtain an estimate of a portion of the signal received on the second sub-carrier which is attributable to the second transmitter. Thus, the receiver (20) is able to determine the portion of the signal received on the second sub-carrier which is attributable to the second transmitter in a way that compensates for the image signal occurring at the second sub-carrier.

Abstract: Channel estimation and/or equalization processing is performed m a wireless receiver in two stages. The first stage involves pre-filtering in the frequency domain to compact a grid-based representation of the net channel. The second stage involves implementing reduced-complexity time domain channel estimation and or equalization. According to one embodiment, a received signal transmitted over a net channel is processed by pre-filtering the received signal in the frequency domain The frequency domain pre-filtering compacts an N-tap effective grid-based representation of the net channel into a K-tap compacted grid-based representation of the net channel where K

Abstract: A change in a time derivative of a branch's received power is determined (402). In response to the absolute value of the received power exceeding (404) a predetermined threshold, a second branch is switched to (406). The determination (402) of the rate of change of the received power can include use of a received-signal-strength indicator. The threshold can be a function of modulation and coding. A rapid change in time derivative of the received power indicates that the branch will soon become frequency selective and that, therefore, the second branch should be switched to (406) in order to avoid the negative affects of the frequency selectivity of the first branch.

Abstract: Techniques for expanding the set of addressable interfering signals in an interference cancelling receiver are described, where the task of control message detection from interfering cells is integrated in an iterative receiver process where increasingly better a priori information on the received data signals from the previous iteration is used to detect additional control messages and successively grow the set of interfering signals included in the receiver's interference mitigation processing. In an example method, first estimated symbols for a desired signal are generated. A control channel corresponding to a first interfering signal is detected, where said detecting is based on the first estimated symbols. Signal characteristics information for the first interfering signal is then derived from the detected control channel signal, and used to generate second estimated symbols for the desired signal, using an interference-mitigation technique to mitigate the effects of the interfering signal.

Abstract: A wireless communication transmitter configured to transmit a multi- carrier signal, the multi-carrier signal being an aggregation of two or more separately modulated carriers occupying distinct frequency regions is operated by obtaining a baseline multi-carrier metric indicative of an amount by which a multi-carrier signal's maximum transmit power should be reduced from a predetermined nominal maximum to satisfy a predetermined out-of-band emission requirement when different scrambling codes are used on all carriers that are combined to create the multi-carrier signal. A compensating metric adjustment value that compensates for an estimation error that results from use of a same scrambling code on two or more of the carriers is estimated. A final multi-carrier metric is obtained by adjusting the baseline metric by an amount based on the compensating metric adjustment value when the same scrambling code is used on the two or more of the carriers.

Abstract: Performing channel estimation with a limited receiver includes performing a first estimation of a first portion of a signal to obtain first parameters of the portion of the signal. The first portion of the signal has predetermined offsets added during transmission. The predetermined offsets are based on the modulation format of a second portion. The first and second portions have different modulation formats. The first portion of the signal is demodulated using the first parameters to recover data symbols. An equalizer is tranined using a decision directed technique to obtain equalizer coefficients. The demodulated first portion of the signal is checked to confirm correct demodulation. The second protion of the signal is then demodulated using the equalizer coefficents.

Abstract: A method and network node (800) for controlling power of uplink transmissions from a user node (802) when switching between a first operating mode and a second operating mode. The network node (800) signals to the user node (802) a first value of a maximum allowed transmit power to be applied when operating in the first operating mode and a second value of the maximum allowed transmit power to be applied when operating in the second operating mode. The user node (802) then uses a transmit power not exceeding the first value when transmitting radio signals in the first operating mode, and uses a transmit power not exceeding the second value when transmitting radio signals in the second operating mode. Thereby, the user node (802) itself regulates the transmit power depending on operating mode without requiring further signalling from the network node (800).
