摘要： Systems and methods are disclosed herein that relate to a wireless device that intelligently uses different reference crystal oscillators (XOs) for a Phase Locked Loop(s) (PLL(s)) in a transceiver of the wireless device. Embodiments of a method of operation of a wireless device comprising a first XO that operates at a first reference frequency and a second XO that operates at a second reference frequency that is greater than the first reference frequency are disclosed. In some embodiments, the method of operation of the wireless devices comprises making a decision as to whether to configure a receiver of the wireless device to use the first XO or the second XO and configuring the receiver of the wireless device to use the first XO or the second XO in accordance with the decision. In a first embodiment the decision is based, on whether or not the wireless device is synchronized to a wireless network and in a second embodiment the decision is based on whether or not a synchronization signal was detected whilst performing an initial cell search.

摘要： The invention relates to a method and an apparatus for operating a limited bandwidth communication device. A communication system node transmits first control channel information on a control channel that extends over a first bandwidth of a radiofrequency resource. The first control channel information is necessary to enable a first type of communication device, capable of receiving a signal having the first bandwidth, to establish a connection with a host cell. A MIB, occupying a second bandwidth-size part of the first bandwidth, is transmitted. The second bandwidth is smaller than the first bandwidth and is receivable by the limited bandwidth, second type of communication device having reduced receive bandwidth capabilities. The MIB has a first part comprising first part information necessary to enable the first type of communication device to establish the connection with the host cell, and a second part comprising second part information directly or indirectly enabling the second type of communication device to obtain parameters that enable connection establishment with the host cell.

摘要： A method of a transceiver arranged to operate according to a Radio Access Technology, RAT, in a cellular communication system is disclosed. The method comprises determining (100) a position value for the transceiver; accessing (104) a database based on the determined position value, wherein a transceiver parameter set corresponding to the position value is acquired, wherein the transceiver parameter set is arranged to adapt operation of the transceiver for the determined position within the RAT; and applying (106) settings of the transceiver according to the acquired transceiver parameter set. A transceiver and a computer program are also disclosed.

摘要： Embodiments herein relate to a method in a transceiver (400) for enabling control of interference cancelling in the transceiver (400). The transceiver (400) is in a first decoding mode. The transceiver (400) stores a received signal comprising a data block. The transceiver (400) decodes the received signal using the first decoding mode, thereby obtaining the data block. When an event is triggered, the transceiver (400) retrieves the stored signal. The transceiver (400) decodes the retrieved signal using a second decoding mode, thereby obtaining the data block. The transceiver (400) controls the interference cancelling in the transceiver (400), based on the data block decoded using the first decoding mode and the data block decoded using the second decoding mode.

摘要： In a mobile communication network comprising a pico base station and macro base station with overlapping coverage areas, the pico base station transmits a supplemental synchronization signal to enable synchronization when the mobile terminal is operating within a link imbalance zone. The supplemental synchronization signal is transmitted using different time, frequency, and/or code resources from the primary and/or secondary synchronization signals to differentiate and separate the supplemental synchronization signals.
