摘要： Data Block Transmission with Variable Retransmission Feedback Time For communicating data between a transmitter (10) and a receiver (14), wireless transmission of data blocks is implemented on the basis a retransmission protocol with variable value of a feedback time. The feedback time defines a time interval between transmission of one of the data blocks (22) and transmission of a feedback message (23) indicating whether the data block (22) was successfully received. The transmitter (10) or the receiver (14) determines the value of the feedback time. Depending on the determined value of the feedback time, the transmitter (10) controls transmission of the data block (22) to the receiver and/or the receiver (14) controls reception of the data block (22) at the receiver (14). The transmitter (10) may for example be a base station of a mobile network, and the receiver (14) may be a terminal device connected to the mobile network. (Fig. 1)

摘要： A node (100; 300) of a mobile network is responsible for scheduling transmissions of data blocks between the mobile network and a terminal device (200, 200'). The node (100; 300) may for example be a base station (100) or a control node (300) of the mobile network. The node (100; 300) determines a processing time required by the terminal device (200; 200') for processing signals for transmission of one of the data blocks. The processing time is determined from a plurality of supported processing times. On the basis of the determined processing time, the node (100; 300) schedules the transmission of the data block. The terminal device (200, 200') may provide control data for determining the processing time to the node (100; 300).

摘要： A communication system node transmits first control channel information on a control channel that extends over a first bandwidth of a radio frequency 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 a 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： 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.

摘要： A method of controlling operation of a communication device arranged to operate in a cellular communication network employing a paging signal to allow discontinuous reception for communication devices is disclosed. The communication device is arranged for three main communication states: detached state where the communication device is not registered to the cellular communication network; idle state where the communication device is registered to the cellular communication network, and receives paging signals through discontinuous reception; and active state where the communication device is registered to the cellular communication network and performs communication with the cellular communication network essentially continuously. The method comprises: i) connecting to the cellular communication network such that a transition from the detached state to any of idle state or active state is made; ii) performing scheduled operations in the active state or idle state; iii) determining, when a transition from the active state to the idle state occurs, time instant for next operation in the active state; iv) disconnecting from the cellular communication network such that a transition to the detached state is made; and v) when the time for next operation in the active state is approaching, returning the procedure to step i). A transceiver and a computer program are also disclosed.

摘要： 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.

摘要： Methods and apparatus taught herein estimate the amount by which to reduce a multi-carrier signal's maximum transmit power based on metrics specific to each carrier of the multi-carrier signal. These carrier-specific metrics may include a maximum-power reduction or cubic metric determined for that carrier as if it would be transmitted alone. In one embodiment, estimation of the required back-off is based on a weighted sum of the carrier-specific metrics, where the weights applied depend on a power ratio. Only a few relatively small look-up tables or simple computations are required in this case one for obtaining the carrier-specific metrics based on configuration parameters of each carrier, and another for obtaining the weights based on the power ratio. Accordingly, methods and apparatus herein advantageously require less computational complexity and/or memory usage than that needed if estimating the required back-off based on similar metrics obtained for the multi-carrier signal as a whole.

摘要： The invention relates to a radio base station and method for a radio base station of a cellular communications system for controlling self- interference. The radio base station supports communication with a user equipment using multiple uplink and multiple downlink carriers. The method comprises detecting a degraded downlink performance on a downlink carrier due to self - interference by determining that a set of predefined conditions applies. The method further comprises executing, in response to detection of the degraded downlink performance, an action to reduce self - interference between the uplink and downlink carriers. The action is one of: uplink scheduling to reduce self - interference, deactivation of a secondary uplink carrier, deactivation of a secondary downlink carrier, and initiation of carrier reconfiguration to reduce self - interference. Accordingly, benefits of using multi - carrier operation may be balanced against a possible associated drawback of degraded downlink performance due to self - interference.
摘要翻译：本发明涉及用于控制自干扰的蜂窝通信系统的无线基站的无线基站和方法。无线电基站支持使用多个上行链路和多个下行链路载波与用户设备进行通信。该方法包括通过确定一组预定义条件适用来检测由于自干扰而导致的下行链路载波上的劣化的下行链路性能。该方法还包括响应于对劣化的下行链路性能的检测而执行减少上行链路和下行链路载波之间的自干扰的动作。该动作是：减少自干扰的上行链路调度，辅助上行链路载波的去激活，二次下行链路载波的去激活以及载波重配置的启动以减少自干扰。因此，使用多载波操作的好处可以与由于自干扰引起的下行链路性能下降的可能的相关缺点进行平衡。
