    Abstract: Uplink reporting and logical channel prioritization in multiflow operation is described. In some embodiments, uplink reporting for multiflow operation utilizes bearer level splitting where the UE associates bearers or logical channel groups (LCGs) with cells for uplink reporting. In some embodiments, uplink reporting for multiflow operation utilizes packet level splitting where the UE groups buffers for all LCGs into a common pool for uplink reporting. In packet level splitting embodiments, the UE may perform uplink reporting based on the total amount of data available for transmission in the common buffer pool or by applying scaling coefficients associated with the serving cells. Some embodiments manage mapping of logical channel payloads to uplink grants for multiflow operation.

    Abstract: A method, an apparatus, and a computer program product for wireless communication where a macro eNB or similar device may be configured to adjust an ABS configuration that is used for designating ABS subframes are provided to provide a VoLTE service to a UE. The ABS configuration may be adjusted by imposing one or more restrictions, such as alignment of the DRX OnDuration of a UE with some offset to the serving cell non-ABS subframes, and imposing restrictions on the ABS subframe settings at the macro eNB. The method or apparatus may initiate or terminate a wireless communication feature for a UE, and may adjust an ABS configuration based on the wireless communication feature, such that a maximum limit is set on a number of ABS subframes or a minimum limit is set on a number of non-ABS subframes based on the wireless communication feature.

    Abstract: Techniques for wireless communication are described, which may include establishing a connection, by a user equipment (UE), with a first and second evolved NodeB (eNB), wherein each of the eNBs provide radio resources to the UE for respective uplink communications; receiving from the first eNB, at the UE, an indication including an allocation of uplink transmit power between the first eNB and at least the second eNB; and transmitting the uplink communications from the UE to the first and second eNBs based on the indication. The techniques may further include coordinating, by a first eNB, multi-connectivity communication for a UE with at least the first eNB and a second eNB; determining for the UE, at the eNB, an allocation of uplink transmit power between the first eNB and at least the second eNB; and transmitting an indication including the allocation of uplink transmit power allocation from the first eNB to the UE.

    Abstract: Systems and methods providing uplink coordinated multi-point (CoMP) communication are shown. A second cell may identify at least one first UE communicating with a first cell and capable of causing high uplink interference to the second cell. The second cell may estimate uplink interference from the at least one first UE at the second cell. The second cell may estimate uplink interference on specific resources. For example, the second cell may determine resources assigned to the at least one first UE for data transmission to the first cell (e.g., using pre-scheduling information provided by the first cell) and estimate uplink interference from the at least one first UE on the resources assigned to the at least one first UE. The second cell may schedule at least one second UE for uplink data transmission to the second cell based on the estimated uplink interference from the at least one first UE.
