    Abstract: A system, method and node for modulation and coding scheme adjustment for a Long Term Evolution (LTE) shared Data Channel. The method determines an actual number of orthogonal frequency division multiplexing (OFDM) symbols, NOS utilized for the shared Data Channel. A modulation order for transmission of data on the shared Data Channel is increased when the actual number of OFDM symbols Nos is less than 11 and decreased when NOS is more than 11. A modulation and coding scheme field (I MCS ) of a downlink control information of the shared Data Channel may also be determined. If o = IMCS +11- NOS = 28, the modulation order is modified by utilizing a factor of (IMCS + 11 - NOS ) in a standardized modulation scheme. If it is determined that IMCS + 11 - NOS 28, the modulation order is set to 64 Quadtrative Amplitude Modulation (64QAM).

    Abstract: A system, method and node for unambiguous encoding of Physical Downlink Control Channel (PDCCH) channels in a Long Term Evolution (LTE) telecommunications system to remove detection errors. The method includes the step of modifying a size of a circular buffer by excluding at least one coded bit from the circular buffer. The circular buffer collects interleaved bits from a PDCCH payload having a plurality of bits. The PDCCH payload is encoded with a convolutional code. The bits of the PDCCH payload are then interleaved. The interleaved bits are collected into the modified circular buffer. The bits are then selected from the modified circular buffer for transmission.

    Abstract: According to methods and apparatus taught herein, user equipments (UEs) in a wireless communication network are scheduled based on determining received signal power densities for a plurality of UEs to be scheduled, allocating UEs to scheduling intervals based on a sorting of their received signal power densities, and assigning UEs in the same scheduling interval to mirror frequency bands within an available frequency spectrum according to the sorting. For example, UEs to be scheduled are assigned to a given scheduling interval in rank order of their received signal power densities until the scheduling interval is fully allocated. Remaining UEs are assigned in rank order to one or more other scheduling intervals, and the process may be repeated or otherwise carried out on an ongoing basis. Such an allocation scheme tends to minimize both adjacent frequency and mirror frequency interferences between UEs scheduled in the same interval.
