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： 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： 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 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： 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： 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 mobile terminal transmits one or more first communication channels in a first frequency region and one or more second communication channels in a second frequency region. With the channels experiencing different fading conditions, the terminal receives separate transmit power control (TPC) commands. Instead of simply adjusting the transmit power of the channels as commanded, the terminal computes a power offset indicative of the difference between the commanded power of one or more of the first channels and the commanded power of one or more of the second channels. The terminal then selectively performs transmit power control of the first and second channels on either an independent basis, according to the respective TPC commands, or a joint basis, depending on whether the computed power offset falls outside of a pre-determined range of values. In doing so, the terminal allows independent control of channels, while also mitigating self-interference and/or spectral emissions.
摘要翻译：移动终端在第二频率区域中的第一频率区域和一个或多个第二通信信道中发送一个或多个第一通信信道。通道经历不同的衰落条件时，终端接收单独的发射功率控制（TPC）命令。代替简单地按照命令调整信道的发射功率，终端计算表示一个或多个第一信道的命令功率与一个或多个第二信道的命令功率之间的差的功率偏移。然后，根据所计算的功率偏移是否超出预定值的范围，终端根据相应的TPC命令或联合基础，独立地选择性地执行第一和第二信道的发射功率控制。在这样做时，终端允许信道的独立控制，同时也减轻自身干扰和/或频谱发射。

摘要： Methods and apparatus are disclosed for reducing mobile terminal energy consumption during data transmissions by allocating link resources and adapting link parameters in an energy-aware manner, based on throughput requirements and prevailing channel conditions. A combination of transmit parameters that includes a transmit channelization scheme and is designed to minimize the total energy consumed during data transmission is selected based on a throughput requirement and one or more channel conditions associated with the data transmission. The channelization scheme includes a number of subchannels to be used and subchannel configuration parameters for each subchannel, such as spreading codes, spreading factors, and subchannel power levels. The combination of transmit parameters may also include a modulation format,\ coding scheme, and transmit power setting, as well as parameters relating to multiple-antenna transmit schemes.

摘要： Methods and apparatus are provided for detecting the radio access technology (RAT) employed in a received signal prior to performing a cell search. The RAT detection method may be used to identify the most likely RAT employed for each candidate frequency identified in an initial frequency scan. Once the most likely RAT is identified, the mobile communication device can then attempt synchronization according to the procedures for the most likely RAT. Identifying the RAT prior to the cell search reduces the number of synchronization attempts and, consequently, the time needed to perform the cell search.
