Abstract: A method and apparatus provide a user equipment (UE) configured to communicate with a plurality of carrier aggregation (CA) groups with at least a first CA group (CG1) and a second CA group (CG2). The UE includes processing circuitry. The processing circuitry is configured to determine whether the UE is power-limited. The UE is scheduled to transmit acknowledged information in a physical uplink shared channel (PUSCH) to a cell of the CG1 and uplink control information (UCI), other than the acknowledgement information, in a physical uplink control channel (PUCCH) to a cell of the CG2. The processing circuitry is also configured to, responsive to the UE being power-limited, prioritize the PUSCH for power allocation. The processing circuitry is also configured to transmit the PUSCH to the cell of the CG1.

Abstract: A method of executing inter-eNB CoMP JT between a CoMP UE and multiple CoMP eNBs is disclosed. A first CoMP eNB constructs a first set of dynamic control information (DCI). The first set of DCI is independently constructed by the first CoMP eNB. The first CoMP eNB transmits the first set of DCI to the CoMP UE. The first set of DCI includes independent DL assignments allowing the first CoMP eNB to perform independent scheduling of a PDSCH associated with the first CoMP eNB. A second CoMP eNB constructs a second set of DCI. The second set of DCI is independently constructed by the second CoMP eNB. Furthermore, the second CoMP eNB transmits the second set of DCI to the CoMP UE. The second set of DCI includes independent DL assignments allowing the second CoMP eNB to perform independent scheduling of a PDSCH associated with the second CoMP eNB.

Abstract: Orthogonal multi-user, multiple input, multiple output (MU-MIMO) multiplexing capacity for demodulation reference signals (DMRSs) is increased without increasing the overhead in resource elements per physical resource block by using length-4 orthogonal cover codes (OCC-4). A base station switches between legacy DMRS antenna port mappings and OCC-4 mapping based upon either a transmission mode or a channel station information process configuration field value.

Abstract: Coordinate multi-point (CoMP) transmission is facilitated by resolving collisions between feedback reporting. Based upon the conditions within the network, collision resolution may be by dropping a channel report during a subframe, multiplexing channel reports from a plurality of user equipment, compressing channel reports a plurality of user equipment, and combined reporting, either through joint reports or by using carrier aggregation, for conditions between a user equipment and a plurality of transmission points. New signaling and reporting formats facilitate selection of a collision resolution suitable for current network conditions.

Abstract translation: 通过解决反馈报告之间的冲突，便于协调多点（CoMP）传输。 基于网络中的条件，冲突解决可以是通过在子帧期间丢弃信道报告，从多个用户设备复用信道报告，压缩信道报告多个用户设备，以及组合报告，通过联合报告或通过 使用载波聚合，用于用户设备和多个传输点之间的条件。 新的信令和报告格式有助于选择适合当前网络条件的冲突解决方案。
