Abstract: A system and method for determining a Physical Uplink Control Channel (PUCCH) power control parameter h(nCQI,nHARQ) for two Carrier Aggregated (CA) PUCCH formats—PUCCH format 3 and channel selection. The value of h(nCQI,nHARQ) may be based on only a linear function of nHARQ for both of the CA PUCCH formats. Based on the CA PUCCH format configured for the User Equipment (UE), the e-Node B (eNB) may instruct the UE to select or apply a specific linear function of nHARQ as a value for the power control parameter h(nCQI,nHARQ), so as to enable the UE to more accurately establish transmit power of its PUCCH signal. Values for another PUCCH power control parameter—ΔF—PUCCH(F)—are also provided for use with PUCCH format 3. A new offset parameter may be signaled for each PUCCH format that has transmit diversity configured.

Abstract: Methods and arrangements for resource allocation in a telecommunication system in which aggregation of component carriers is applied. The size of the resource allocation field is determined based on the transmission bandwidth of a selection of component carriers. The selection of component carriers comprises the component carrier on which the resource allocation message is monitored and the component carriers which are cross-scheduled from said component carrier. The resource allocation message comprising the resource allocation field with the determined size is transmitted to the user equipment over a particular component carrier of the selection of component carriers. Furthermore, with only one size of the resource allocation field a smaller number of code word sizes needs to be monitored by the UE. This leads to a smaller number of blind decodings performed in the UE. The present invention enables a more tailored approach when determining the size of the resource allocation field to avoid too high overhead but also a too coarse resource allocation.

Abstract: In various embodiments, a method for transmitting uplink control information in a cell is provided. The uplink control information is transmitted during a time slot. According to this method, bits corresponding to uplink control information are mapped to complex modulation symbols. The complex modulation symbols are spread in the time slot using a set of orthogonal cover code, OCC, sequences, such that at least two of the complex modulation symbols are spread using different OCC sequences. The uplink control information is then transmitted using said spread complex modulation symbols.

Abstract: Power headroom reporting and report handling are discussed in the context of a Physical Uplink Shared Channel (PUSCH), on which a user equipment (UE) has no valid uplink grant, and a Physical Uplink Control Channel (PUCCH) on which a UE has no transmission. Under these circumstances, it is not possible to directly calculate one or more parameters which are used to calculate power headroom. Accordingly, exemplary embodiments provide for predetermined, known values to be used by the UE to calculate the power headroom, and by the eNodeB to understand the meaning of a received power headroom report.

Abstract: Embodiments herein include a method in a user equipment (UE) for transmitting uplink control information in time slots of a subframe over a radio channel to a radio base station. The uplink control information is comprised in a block of bits.The UE maps the block of bits to a sequence of complex valued modulation symbols. The UE block spreads the sequence across Discrete Fourier Transform Spread—Orthogonal Frequency Division Multiplexing (DFTS-OFDM) symbols. This is performed by applying a spreading sequence to the sequence of complex valued modulation symbols, to achieve a block spread sequence of complex valued modulation symbols. The UE further transforms the block-spread sequence, per DFTS-OFDM symbol. This is performed by applying a matrix that depends on a DFTS-OFDM symbol index and/or slot index to the block-spread sequence. The UE also transmits the block spread sequence, as transformed, over the radio channel to the radio base station.
