    Abstract: Embodiments of the invention are directed to a cellular communication network that can determine whether communications between one base station-UE pair may interfere with another UE that is in the same cell or a different cell. The network identifies interference parameters associated with interference signals that may be received by a UE. The interference signals may be generated by the base station itself, such as communications with other UEs, or by a neighboring base station. The base station transmits the interference parameters to the UE. The UE receives the one or more parameters comprising information about signals expected to cause intra-cell or inter-cell interference. The UE then processes received signals using the one or more parameters to suppress the intra-cell or inter-cell interference.

    Abstract: Systems and methods for selecting Physical Uplink Control Channel (PUCCH) resources are disclosed. An Enhanced Physical Downlink Control Channel (EPDCCH) is detected in signals received from a base station in a first subframe. A HARQ-ACK resource indicator offset (ΔARO) value is identified for the EPDCCH. A PUCCH resource is selected for transmission of a Hybrid Automatic Repeat reQuest-ACKnowledgement (HARQ-ACK) corresponding to the EPDCCH. The PUCCH resource is selected based upon the ΔARO value. The ΔARO value may correspond to a semi-statically configured PUCCH resource. A second PUCCH resource may be selected for transmission of the HARQ-ACK on a second antenna port. A HARQ-ACK resource offset field value may be detected in a Downlink Control Information (DCI) format of the EPDCCH. A table that maps the HARQ-ACK resource offset field value for certain DCI formats to ΔARO values may be used to determine the ΔARO value for the EPDCCH.

    Abstract: This invention is a technique for coordinate multi-point wireless transmission between a plurality of geographically separated transmission points (TP) and at least one user equipment (UE).
    For coordinated multi-point communication (CoMP), UE measures the downlink wireless propagation channel corresponding to multiple geographically separated transmission points. The network configures multiple channel state indicator-reference signal (CSI-RS) resources, each of which is associated with a TP. UE measures the downlink channel using the multiple configured CSI-RS resources, and reports multiple CSIs in the uplink feedback channel. Each CSI report is defined as a “CSI-process”, where a CSI-process with a lower CSI-process-index has a higher priority. Multiple CSI-processes can be reported periodically. Each periodic CSI feedback comprises a single CSI-process. Different CSI-processes are time-domain-multiplexed on different uplink feedback time instances, and are not multiplexed in the same feedback time instance. If two CSI-processes collide in the time domain, the CSI-process of a higher priority is reported, and the CSI-process of a lower priority is dropped. The UE can also feedback multiple CSI-processes in an aperiodic manner, where multiple CSI-processes are reported simultaneously. Aperiodic feedback by the UE is triggered by an n-bit CSI-triggering field in an uplink grant transmitted by the network. Each codepoint of the n-bit triggering field triggers feedback of a subset of CSI-processes configured by the higher-layer. If a UE is configured with CoMP and without carrier aggregation (CA), CSI-processes are ordered by decreasing CSI-process priority. If a UE is configured with CoMP and carrier aggregation simultaneously, CSI-processes are ordered firstly by decreasing carrier index, and secondly by decreasing CSI-process priority.
