Abstract: A system and method to instruct a user equipment (UE) how Uplink Control Information (UCI) on a Physical Uplink Shared Channel (PUSCH) should be transmitted with carrier aggregation. A semi-static signaling of a UCI mapping bit (via a Radio Resource Control (RRC) parameter) is used by a base station such as an eNodeB to require the UE to transmit UCI using one of two pre-determined UCI transmission modes. The bit can be decided by the base station, considering, for example, the available bandwidth or quality of different Uplink Component Carriers (UL CCs) associated with the UE. This network-based solution allows the network to either configure a general rule of UCI transmission by the UE or to enforce the UCI transmission on the Uplink Primary cell (UL Pcell). Because of the rules governing abstracts, this abstract should not be used to construe the claims.

Abstract: Systems and methods are disclosed herein for configuring a wireless device individually (i.e., separately) per uplink subframe set as to whether or not the wireless device can use uplink 256 Quadrature Amplitude Modulation (256QAM). In some embodiments, a method of operation of a network node comprises configuring a wireless device for use of a Modulation and Coding Scheme (MCS) table for uplink 256QAM separately per uplink subframe set for two or more uplink subframe sets. In some embodiments, the two or more uplink subframe sets are two or more uplink subframe sets for separate uplink power control. In this manner, 256QAM can be utilized in more subframes and, as a result, uplink data rate can be increased.

Abstract: Systems and methods provide for an increase in hearability by a user equipment (UE, 116). This increase in hearability can be used to improve positioning results. Two different types of positioning subframes can be transmitted by cells in a radio access network (RAN) to improve hearability: measurement subframes and low-interference subframes. The selection of which type of positioning subframe to transmit can be determined algorithmically by the transmitting entity.
