Abstract: A method and network entity for enabling higher order modulation (HOM) mode support for HOM capable wireless devices. The method includes determining a legacy mode power offset value for HOM mode capable wireless devices in legacy modulation mode and calculating a power headroom value for sending downlink data to the HOM mode capable wireless devices. When the power headroom value exceeds a threshold value, the HOM mode support for the HOM mode capable wireless devices is enabled using the identified legacy mode power offset value. When the power headroom value does not exceed the threshold value, and a HOM mode power offset value is available, the HOM mode power offset value being less than the legacy modulation mode power offset value, the HOM mode support for the HOM mode capable wireless devices is enabled using the HOM mode power offset value.

Abstract: Method in a network node of mapping one or more messages onto transmission resource for transmitting to a wireless device. The one or more messages are processed by the network node. The network node and the wireless device are adapted to be comprised in a wireless communications network. The network node maps the one or more processed messages onto the transmission resource. This is performed according to indexing information comprised in the one or more messages, and to a precalculated mapping table. The precalculated mapping table is calculated prior to obtaining the one or more messages to be mapped. The network node, the communications network, a second network node, a core network node in the wireless communications network, and methods therein are described.

Abstract: A method and system for managing a transmission buffer memory at a base station in a wireless communication system, the base station having a plurality of cells, the memory being circular and shared among the cells so that memory fragmentation when cells are removed or added is avoided.

Abstract: A downlink physical layer processing system includes a transport block segmentation processor that receives a transport block and generates segmented blocks from the transport block, an encoder that encodes the segmented blocks and forms encoded blocks, a mapping processor that maps the encoded blocks to symbols corresponding to resource elements to generate mapped symbols for transmission over a transmission medium, and a transmission signal generator that processes the mapped symbols to generate transmission signals for transmission over the transmission medium. The mapping processor maps the encoded blocks to the symbols in response to a control signal generated by the transmission signal generator. The encoder thereby operates in response to timing of data received by the encoder while the mapping processor operates in response to timing of processing of symbols by the transmission signal generator.
