Abstract: A UE is configured to receive an RRC message including first information containing a frequency hopping mode, a periodicity and a number of repetitions, and second information containing a slot offset, a time domain allocation indicating a start symbol and a length, a frequency domain allocation, and a frequency hopping offset. The UE is configured to determine, according to the first and second information, a plurality of PUSCH resources for repetitions of a transport block. A first one of the plurality of PUSCH resources is determined based on the periodicity, the slot offset, the time domain allocation, and the frequency domain allocation. The remaining ones of the plurality of PUSCH resources are to use consecutive slots. The UE is configured to transmit, on the plurality of PUSCH resources, the repetitions of the transport block, where the repetitions start on the first PUSCH resource associated with Redundancy Version 0.

Abstract: A method for reporting uplink control information (UCI) on a user equipment (UE) is described. A collision of multiple channel state information (CSI) reports corresponding to multiple component carriers (CCs) that are scheduled to be reported in the same subframe is detected. A highest priority CSI report of the multiple CSI reports is determined using a prioritization scheme. The highest priority CSI report is transmitted.

Abstract: The present disclosure relates to component carrier (CC) selection in a wireless communication system. A user equipment (UE) that is in idle mode may receive a reference signal (RS) from an evolved Node B (eNB), obtain signal quality measurements with respect to the RS, and switch to a new CC based on the signal quality measurements. For a UE that is in connected mode, an eNB may obtain uplink channel condition information corresponding to uplink CCs, obtain downlink channel condition information corresponding to downlink CCs, and select a CC pair for the UE to use based on the uplink channel condition information and the downlink channel condition information.

The UE also sends SCell Physical Downlink Shared Channel (PDSCH) HARQ-ACK information in the HARQ-ACK reporting subframe.

Abstract: A wireless communication device may autonomously transition from a multiple antenna port mode to a single antenna port mode. The wireless communication device may implicitly notify a base station about the autonomous transition from the multiple antenna port mode to the single antenna port mode. The base station may reallocate resources that were previously allocated to the wireless communication device but that are no longer being used by the wireless communication device. In some cases, the base station may configure the wireless communication device's antenna port mode via radio resource control signaling.

Abstract: Input data may be coded in accordance with a coding method that allows for either coded data or messages to be transmitted with pre-determined, but unequal reliability over a communication channel. The coding method may allow the messages to be transmitted with higher reliability than the coded data. Messages may be transmitted when they are available. Otherwise, the coded data may be transmitted.

Abstract: A method for generating sequences that are nearest to a set of sequences with minimum average cross-correlation is described. Each element of a set of sequences is projected to a nearest constellation point. The set of sequences is converted into a time domain representation. An inverse discrete Fourier Transform (IDFT) is performed on the set of sequences. A cubic metric of each sequence of the set of sequences is evaluated. A sequence is removed from the set if the cubic metric exceeds a threshold. A minimum maximum cross-correlation is obtained for the set of sequences.

Abstract: A method for assigning and coordinating uplink reference signals for cooperative communication is disclosed. Data about an assigned uplink reference signal sequence used by a wireless communication device is received at a non-serving base station. An uplink reference signal estimate is determined based on the data. The uplink reference signal estimate is used to coherently demodulate a signal received from the wireless communication device or is used to estimate an uplink channel between the non-serving base station and the wireless communication device.

Abstract: A method for transmitting uplink control information (UCI) using a physical uplink control channel (PUCCH) transmit diversity scheme is described. A UCI is coded with a Forward Error Correction code to obtain a coded UCI. The coded UCI is mapped to quadrature phase shift keying (QPSK) symbols to obtain a mapped coded UCI. A phase shift pattern is selected. A phase shift from the phase shift pattern is applied to the mapped coded UCI based on an acknowledge/negative-acknowledge (ACK/NACK) to obtain a phase shifted mapped coded UCI. The mapped coded UCI is sent using a PUCCH resource on a first antenna. The phase shifted mapped coded UCI is sent using a PUCCH resource on a second antenna.
