Abstract: A solution for radio resource allocation in a cellular telecommunication system is provided. According to the invention, the frequency bands of a plurality of cells of the telecommunication system are divided independently into more than one frequency band sub-block. User terminals within the coverage area of each cell are then allocated to the frequency band sub-blocks on the basis of the modulation and coding schemes used by the user terminals. Furthermore, transmission power of the user terminals is controlled on the basis of the allocation of the user terminals in order to improve data throughput.

Abstract: From the network perspective, an uplink resource allocation (PDCCH) is sent that grants an uplink resource to a plurality of user equipments UEs, and the allocation has an indication of a cyclic shift CS for each of the plurality of UEs. The granted uplink resource is mapped to a downlink resource (PHICH) in dependence on the indicated CS for each of the plurality of UEs. The mapping is such that for a predetermined number of UEs being allocated a same uplink resource in a single MU-MIMO uplink resource allocation grant, each pair of said predetermined number of UEs which map to an adjacent downlink resource exhibit an optimized CS relative to one another. The network sends to each of the respective plurality of UEs on the respective mapped downlink resource an indication (ACK/NACK) about data received (on a PUSCH). Apparatus, method, and computer programs for network and UE side implementations are detailed.

Abstract: A reference signal cyclic shift (CS) is quantized as a combination of a cell specific CS with an outcome of a pseudo-random hopping, and an indication of the cell specific CS is broadcast in the cell. In one embodiment the CS is quantized as a modulo operation on a sum of the cell specific CS, the outcome of the pseudo-random hopping, and a user specific CS, in which case an indication of the user specific CS is sent in an uplink resource allocation and a user sends its cyclically shifted reference signal in the uplink resource allocated by the uplink resource allocation. The CS may also be quantized according to length of the reference signal as cyclic_shift_symbol=(cyclic_shift_value*length of the reference signal)/12; where cyclic_shift_value is between zero and eleven and cyclic_shift_symbol is the amount of CS given in reference signal symbols.
