    摘要： There are provided measures for mobility in heterogeneous network environments, said measures exemplarily including configuring, at a network entity, and/or transmitting, from the network entity to one or more terminals, one or more terminal-unspecific handover qualification data defining a qualification of one or more cells for handover cell selection depending on a terminal speed, autonomously determining a terminal speed, and selecting one or more cells for handover cell selection using the received one or more handover qualification data on the basis of the determined terminal speed. Said measures may exemplarily be applied for mobility procedures in heterogeneous network environments based on LTE, LTE-Advanced, HSPA and/or UMTS radio access systems.

    摘要： A cell informs surrounding cells about an orthogonal resource allocation strategy of the informing cell so as to induce cooperative behavior among the cells. The informing cell also receives resource allocation strategies from the surrounding cells. Each cell allocates its orthogonal resources according to the mutually exchanged information. The result is to reduce interference in the system. For example, a BS informs other cells on which clusters it generates a small interference, e.g., close UEs concentrated into a particular cluster, and indicate that to its neighbors. Other cells would concentrate UEs which are on the edge to the indicating cell exactly in this cluster. This would mean an “overload invitation”, i.e. inviting the neighbors to produce overload on a particular cluster. If a cell sends an overload invitation on a sufficiently large cluster, this will automatically reduce the interference in the other clusters.

    摘要： Wireless channel interference information is determined (e.g., a background interference matrix BIM constructed from multiple user equipment measurements). Reliability of the interference information is classified and sent with the interference information to a neighbor network access node such as a HeNB. In various embodiments there are three layers of reliability, the above being the first. The second layer utilizes variability of a plurality of such reliability indications received from the same neighbor HeNB, which is updated as new interference information and reliability indications are received from that same neighbor HeNB. The third layer utilizes a peer review/update process on the neighbor HeNBs themselves, where each HeNB's performance is shared among all and updated by one another as different HeNBs utilize one another's BIM and assesses how reliably it reflected actual interference conditions. This addresses concerns for data/source reliability since communication interfaces among HeNB groups may not be controlled by a single network operator.

    摘要： An apparatus, method, system and computer program product provide control channel coordination in heterogeneous networks. Parameters are provided indicating the availability of resources, wherein a resource is defined as an available radio frequency per time interval, and parameters indicate configuration of a physical channel configured for downlink control, for a physical control channel configured for format indication, and for a physical channel configured for HARQ indication, for use in both of two different communication cells providing radio communication services for terminals located therein. Further, a first resource allocation set and a second resource allocation set are determined, wherein determinations of the first resource allocation set and the second resource allocation set are made to be as mutually disjoint in resource allocation as possible in consideration of the parameters.

    摘要： A network access node eNB sends to a user equipment UE a pattern of subframe measurement restrictions and an indication of how to utilize the pattern for measuring subframes. The indication may select from among: the UE's own-cell measurements; the UE's neighbor-cell measurements; both same and neighbor-cell measurements, and no measurement restrictions. The eNB may generate the pattern from an almost-blank subframe ABS pattern for the UE's own-cell and of its neighbor-cell. The pattern and indication may be sent in separate RRC messages, or if sent in one message there is a second indication sent in a second RRC message instructing the UE to terminate utilizing the pattern and indication for restricting its subframe measurements. Embodiments are particularly useful for inter-cell interference mitigation eICIC for the LTE-Advanced system.
