摘要： Embodiments herein relate to a method performed by a transmitting device (12) for transmitting information bits to a receiving device (10) in a wireless communication network (1). The transmitting device (12) encodes information bits of a first type of information and a second type of information into a codeword. The transmitting device (12) interleaves the encoded information bits of the first type of information according to a first interleaving pattern and the encoded information bits of the second type of information according to a second interleaving pattern, thereby changing an order of the encoded information bits of at least one of the first type of information and the second type of information in the codeword and generating an interleaved encoded information bit sequence. At least one of the first and the second interleaving pattern is designed to allow the information bits of a first type of information to be decoded without knowing a length of the codeword. The transmitting device then transmits the interleaved encoded information bit sequence to the receiving device (10).

摘要： A control node (26) of a radio access network (24) comprises a soft handover unit (62) and a power control unit (50). The soft handover unit (62) controls a soft handover procedure wherein a user equipment unit (30) has diversity in radio transmissions with plural radio base stations (28) comprising an active set of base stations. The power control unit (50), during the soft handover procedure, facilitates an adjustment of an uplink power level used by the user equipment unit (30) for uplink radio transmissions to the plural base stations by an adjustment amount. The adjustment amount is determined to promote uplink synchronization for all radio base stations of the active set. In one example embodiment, the power control unit (50) comprises a soft handover power boost function (70) which, during the soft handover procedure, increases the uplink power level used by the user equipment unit (30) for uplink radio transmissions by the adjustment amount. The adjustment amount is preferably a function of a difference between power levels of downlink reference signals of the active set.

摘要： A method and a network node (300) for enabling wireless communication with a wireless device (302), wherein no more than a pre-determined maximum total transmit power is available for downlink transmission by the network node (300). When detecting that the wireless device (302) requires an extended transmission range (300B) which is larger than a nominal transmission range (300A), a boosted transmit power is determined and used for transmitting a first set of channels and/or signals to be used by the wireless device (302) to achieve the extended transmission range (300B). An attenuated transmit power is also determined and used for transmitting a second set of channels and/or signals not included in the first set of channels and/or signals, which provides a slightly reduced transmission range (300C) for the second set. The boosted transmit power is thus higher than a nominal transmit power, and the attenuated transmit power is lower than the nominal transmit power, so that the total transmit power used for transmitting said first and second sets does not exceed the pre-determined maximum total transmit power.
