Abstract: Methods and apparatus are provided for a base station to transmit repetitions of broadcast information and for a UE to detect the broadcast information. In a first method, the base station maps each repetition in a respective quadruple of subframe symbols while accounting for a possible different number of available sub-carriers among quadruplets of subframe symbols. In a second method, the base station maps the repetitions successively in available sub-carriers. For intermittent transmissions of repetitions, the UE can use the mapping structure of the repeated broadcast information to determine an existence of a transmission.

Abstract: Methods and apparatus are provided for a User Equipment (UE) and a base station in communication with each other to determine parameters for a Random Access (RA) process. The base station informs the UE through a System Information Block (SIB) of a number of resource sets for RA preamble transmission by the UE. Each resource set is associated with a number of repetitions for a RA preamble transmission, with a maximum number of RA preamble transmissions, and with a number of repetitions the base station transmits a response to a RA preamble reception. The SIB also informs an association between a range of path-loss values and a number of RA preamble repetitions. The UE determines a number of repetitions for a first RA preamble transmission from its path-loss measurement.

Abstract: A user equipment (UE) is configured by a Master enhanced NodeB (MeNB) for operation with dual connectivity to a Secondary eNB (SeNB) to transmit acknowledgement information when the UE is power limited and for a respective eNB to determine a UE power limitation. The UE, the MeNB, and the SeNB adjust operation according to a partitioning of a UE capability between the MeNB and the SeNB. The UE capability can be a transmission power, a soft buffer size, a reception or a transmission of a number of data transport block bits, or a number of decoding operations.
