Abstract: The present invention provides a method, apparatus and system for handling unreliable feedback information in a wireless network. The present invention adjusts one or more communications (202) with a receiving unit (272) in a wireless communication network by receiving feedback information (302) relating to the receiving unit (102), determining a feedback information offset for the receiving unit (272), and adjusting the one or more communications (202) with the receiving unit (272) based on the feedback information and the feedback information offset (306).

Abstract: The application relates to a low power network node, LPN, and a method performed thereby for providing a primary serving cell to a wireless device associated with the low power network node are provided. A wireless device and a method performed thereby for camping on a cell in a wireless communication network when the wireless device is in an idle mode of operation are also provided. The wireless communication network also comprises a neighbouring network node, wherein the low power network node and the neighbouring network node are configured with a first set of frequency bands B' and the low power network node is configured with a second set of frequency bands B". The second set of frequency bands B" is specific for the LPN and the neighbouring network node is not configured with the second set of frequency bands B". When there is a dominance problem due to the LPN (420) and the neighbouring network node (430) using the same set of frequency bands, the wireless device (410) may experience problems receiving transmissions from the LPN on carriers in that set of frequency bands. One solution may be to hand over the wireless device to the neighbouring network node. However, then the neighbouring network node may become overloaded as it may be serving a large amount of wireless devices (435A, 435B). Thus, the LPN is configured with the second set of frequency bands B" which are not used by the neighbouring network node. Since the neighbouring network node does not use the second set of frequency bands B", the neighbouring network node may not cause interference on carriers of the second set of frequency bands B". However, since the number of carriers in the second set of frequency bands, B", generally is less, or even much less, than the number of carriers in the first set of frequency bands, B', the carriers in B" may relatively soon be all used up. Consequently, the LPN wants to, at the same time, minimise the use of carriers in B". This is achieved to use the second set of frequency bands B" only when the signal quality for carriers in the first set of frequency bands B' used by the LPN is lower than the received signal quality for carriers in the first set of frequency bands B' used by the neighbouring network node as measured by the wireless device.

Abstract: An apparatus, method, and system for dynamically assigning orthogonal codes to different information signals communicated between a Node B (52) and user equipment (11) in a cellular radio communication system in which a fixed number of codes are allocated between dedicated transport channels, DCHs, and high speed downlink shared channels, HS-PDSCHs. A radio controller, RNC, (55) allocates a minimum number of codes for HS-PDSCHs to the Node B (52). The Node B determines codes that are not currently being utilized and allocates HS-PDSCH codes from the unused codes with out having to communicate with RNC (55). When the additional HS-PDSCH codes are needed for DCH codes, the Node B reallocates the codes for DCH purposes without reducing the number of HS-PDSCH codes below the allocated minimum.
