摘要： A method of Coordinated Multipoint (CoMP) communication between a base station having a plurality of points with at least one user equipment (UE). At least one UE receives at least one transmission from the base station having the plurality of points. This UE measures downlink channel state information for each of the plurality of points including a rank indicator (RI), a precoding matrix indicator (PMI) and a channel quality indicator (CQI). This UE transmits the downlink channel state information in an uplink feedback channel to the base station.

摘要： The primary serving base station transmits PDSCH with zero energy on the inter-cell CRS resource element location. This is called mute PDSCH. Within the first Physical Resource Block (PRB 0), the RE positions in the frequency domain are indexed between 0 and 11. The muted PDSCH RE positions per antenna port are computed using the cell IDs of all CoMP cells other than the cell ID i. The invention defines the Orthogonal Frequency Division Multiplexing (OFDM) symbols in which muting occurs.

摘要： A base station selects a subset of at least one geographically separated antennas for each of the plurality of user equipments. The base station forms at least layer of data stream including modulated symbols, precodes the data stream via multiplication with the NT-by-N precoding matrix where N is the number of said layers and NT is the number of transmit antenna elements and transmits the precoded layers of data stream to the user equipment via the selected geographically separated antennas. The base station signals the subset of the plurality of geographically separated antennas via higher layer Radio Resource Control or via a down link grant mechanism. The base station optionally does not signal the subset of the plurality of geographically separated antennas to the corresponding mobile user equipment.

摘要： In one embodiment, an object is stored in a k-dimensional forest that has a plurality of k-dimensional trees and each k-dimensional tree has a different size. If the smallest k-dimensional tree in the k-dimensional forest is not full, then the object is stored as a specific node in the smallest k-dimensional tree. Otherwise, a first k-dimensional tree in the k-dimensional forest is located, which is the smallest k-dimensional tree in the k-dimensional forest that is capable of storing the first object, objects in one or more second k-dimensional trees from the k-dimensional forest that are smaller than the first k-dimensional tree, and objects currently in the first k-dimensional tree. The object is stored as a specific node in the first k-dimensional tree. In addition, the objects in the second k-dimensional trees are moved and stored as specific nodes in the first k-dimensional tree.

摘要： This invention mitigates interference in wireless telephony in heterogeneous networks having a macro base station and a low power base station. This invention attempts to avoid cross carrier scheduling on an anchor carrier and a non-anchor carrier. If cross carrier scheduling is unavoidable, then this invention attempts: (1) semi-statically signalling a CFI value on a cross-scheduled component carrier; (2) semi-statically signalling a channel quality information (CSI) value on a cross-scheduled component carrier setting a Physical Hybrid ARQ Indicator CHannel (PHICH) value to be maximum; or (3) semi-statically signalling a channel quality information (CSI) value on a cross-scheduled component carrier using Physical Control Format Indicator CHannel (PCFICH) power boosting on cross-scheduled component carriers (CC).

摘要： A system and method are provided wherein one or more femtocell base stations are deployed within a range of a cellular base station and utilize substantially the same frequency band as the cellular base station. Each femtocell base station may be configured to employ one or more interference avoidance techniques such that coexistence between the cellular and the corresponding femtocell base station is enabled. The interference avoidance techniques employed may include use of randomized time or frequency hopping; randomly selecting a predetermined number, or identifying one or more unutilized, frequency subchannels for signal transmission; using two or more transmit and two or more receive antennas; nulling one or more transmissions in a direction of a nearby cellular base station user; handing off at least one cellular user to one of the femtocell base stations and vice versa; and/or reducing the transmission power of at least one femtocell base station.
