摘要： Teachings presented herein provide a method (100) and apparatus (10) for processing input information bits (16) for coding using a code (20), such that the length of the information word (14) formed from the input information bits (16) matches a fixed information word length defined by the code 20. In at least one embodiment, a coding circuit (10) receives input information bits (16) and adds error protection bits (26) as needed, to make the information word length match the fixed information word length. The method (100) and apparatus (10) contemplate generating the error protection bits (26) by sub-coding a subset (28) of the input information bits (26) (e.g., parity bit generation), thereby providing extra protection for that subset (28). These teachings allow the same code (20) to be used for coding feedback or other information, where the amount of information to be coded varies as a function of operating modes.

摘要： A method and apparatus for code multiplexing one or more control signals onto a shared control channel. According to the present invention, a control signal for transmission from a base station to a mobile station terminal is repeated in each slot of a predetermined time interval. The control signal in each slot is spread using a bit-level spreading sequence, where the bit-level spreading sequence varies from slot to slot according to a predefined sequence-hopping pattern. The spread control signals generated for transmission to each mobile station terminal are then combined and spread using a common channelization code.

摘要： Exemplary combining weight generation is based on estimating received signal impairment correlations using a weighted summation of interference impairment terms, such as an interference correlation matrix associated with a transmitting base station, and a noise impairment term, such as a noise correlation matrix, the impairment terms scaled by fitting parameters. The estimate is updated based on adapting the fitting parameters responsive to measured signal impairment correlations. The interference matrices are calculated from channel estimates and delay information, and knowledge of the receive filter pulse shape. Instantaneous values of the fitting parameters are determined by fitting the impairment correlation terms to impairment correlations measured at successive time instants and the fitting parameters are adapted at each time instant by updating the fitting parameters based on the instantaneous values.

摘要： A pilot channel signal for time-division multiplexing with one or more traffic channel signals in a broadcast/multi-cast signal and for code-division multiplexing with a continuously transmitted pilot channel signal is described. In an exemplary method for transmitting a broadcast/multicast signal, a pilot symbol sequence is obtained for each slot of one or more frames of the broadcast/multicast signal, so that the pilot symbol sequence varies for each slot of a given frame. The pilot symbol sequence for each slot is spread with a channelization code, and the spread pilot symbol sequence for each slot is scrambled, using a scrambling code, to form a first pilot channel signal. The first pilot channel signal is transmitted so that it is time-division multiplexed with one or more traffic channel signals transmitted during each slot and code-division multiplexed with a second pilot channel signal transmitted during all slots of the one or more frames.

摘要： According to a first aspect of embodiments herein, the object is achieved by a method in a network node for assisting a first user equipment in interference mitigation. The network node is comprised in a cellular communications network. The cellular communications network further comprises the first user equipment and a second user equipment. The second user equipment causes interference to the first user equipment when at least one of the first user equipment and second user equipment communicate by using Device-to-Device, D2D communication. The network node obtains (202) information about the receiver of the first user equipment. The network node then determines (203) one or more parameters required by the first user equipment for mitigating the interference. The parameters relate to the obtained information and to the interfering second user equipment. The network node then sends (204) the one or more parameters to the first user equipment thereby assisting the first user equipment to mitigate interference caused by the second user equipment.

摘要： A system and method in which a base station (34) treats the Channel State Information, CSJ. from wireless terminals (28, 29) as only partially- stale, and exploits this partially-stale CSi to predict the current channel from old estimates of the channel. The predicted channel is then used to design a precoder (60). The base station shapes the transmitted signal with the precoder so as to match it as closely as possible to the current channel. Particular embodiments of the disclosed solutions thus combine the benefits of the stale feedback scheme with preceding to match the channel. As a result, the signal received at a terminal (28, 29) is better conditioned, thereby providing a greater overall boost ra performance of the communication arrangement between the base station (34) and the terminal (28, 29). The usage of partially-stale CSI can be important for dense networks with a large number of simple terminals.
