An apparatus is described which includes a transceiver configured to be connectable to a first network node by a first uplink connection and at least a second network node by a second uplink connection. Uplink control signalling is generated independently for each network node, wherein the generated uplink control signalling for the first network node is sent via the first uplink connection, and the generated uplink control signalling for the second network node is sent via the second uplink connection.

An apparatus is described which includes a network interface configured to receive and/or send data for a user equipment from and/or to a network, a processor configured to control a split of the data for at least two component carriers, and a transceiver unit configured to perform a downlink and/or uplink transmission with a user equipment via at least a first one of the at least two component carriers, wherein the processor is configured to send and/or receive the data of at least a second one of the at least two component carriers to and/or from a slave network node

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.

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.

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.

The application relates to wireless transmission of load status information for load balancing among Home Node Bs (HNB) or Local Area Node Bs (LNB) for which an X2 interface is not available. In particular, an LNB may pretend to be a user equipment with a specific predefined user equipment ID value. A neighboring LNB which receives a data packet with this user equipment ID value knows that the data packet contains load information monitored, by a neighboring LNB.
摘要:
A method and apparatus for controlling retransmissions of subframes is disclosed. In the method the type of a received subframe is determined. Identification of the subframe for retransmission purposes is then controlled based on the determined type of the subframe. A node receiving a request for retransmission of the subframe provided with an identification based on the type of the subframe determines based on the identification for retransmission purposes the subframe for which retransmission is requested.
摘要:
According to several embodiments of the present invention, an apparatus (e.g., a UE) monitors a set of component carriers by referring to sub-bands having a sub-band size. The channel quality of the component carriers is detected, best component carriers are identified based on the channel quality, the number of the best component carriers is identified, and the subband size is varied based the identified number of the best component carriers. Identification information and channel quality information on the best component carriers may then be provided, for example to a network control element such as an eNode-B.
