摘要： A radio resource management, RRM, apparatus for at least one wireless communication network macrocell is provided. The macrocell includes at least a first coverage region and second coverage region. The RRM apparatus includes a processor that is configured to determine at least one scheduling block, SB, for use by at least one user device. The determination of the at least one SB is based at least in part on a first noise metric when the at least one user device is located within the first coverage region. The determination of the at least one SB is based at least in part on a second noise metric different from the first noise metric when the at least one user device is located within the second coverage region.

摘要： A channel estimation system disclosed herein jointly estimates the channels for users transmitting signals allocated overlapping frequency resources in a received composite wideband signal. The channel estimation system may further limit the joint channel estimation process to only locally scheduled UEs and those desired users transmitting detectable desired signals using frequency resources at least partially overlapping the locally scheduled UE's frequency resources. More particularly, a local base station processes the received composite wideband signal to determine which of the potential desired user(s) have transmitted user signals allocated frequency resources that at least partially overlap the frequency resources allocated to locally scheduled users and having a sufficient signal strength and quality to be detectable as present in the received signal. The local base station processes the local and detected desired user signals in the received signal to jointly calculate channel estimates for the corresponding users based on the corresponding reference sequences.

摘要： Systems and methods are disclosed for controlling cell selection between a high power base station and a neighboring low power base station in a cellular network. In one embodiment, a primary direction of traffic flow for a user equipment located within a transition zone between a high power base station cell of the high power base station and a low power base station cell of the low power base station is determined to be either an uplink direction or a downlink direction. Cell selection for the user equipment is then controlled based on the primary direction of traffic flow for the user equipment such that selection of the high power base station cell is favored if the primary direction of traffic flow is the downlink direction and selection of the low power base station cell is favored if the primary direction of traffic flow is the uplink direction.

摘要： Embodiments herein provide reduced backhaul bandwidth requirements for Coordinated Multi-Point reception of an uplink signal. A cooperating base station receive and demodulates the uplink signal to produce soft output values that each indicate the value of a corresponding information symbol in the uplink signal and the level of certainty in that symbol value. The cooperating base station then selectively sends particular ones of the soft output values to a serving base station over a backhaul communication link based on whether or not the level of certainty indicated by each soft output value exceeds a certainty threshold. The serving base station likewise receives and demodulates the uplink signal to produce its own soft output values. The serving base station then combines respective ones of the soft output values it received from the cooperating base station and the soft output values it produced itself that are associated with the same information symbol.

摘要： A method of interference management of multiuser in-coverage device-to-device communications at a network node is presented. A WAN signal from a WAN device is received, the WAN signal being mixed with an interferer signal caused by a D2D communication between a transmitting D2D device and a receiving D2D device of a D2D pair. An attribute value difference between a first attribute value of the WAN signal and a second attribute value of the interferer signal is determined. If the attribute value difference does not meet a target difference, a transmission parameter of at least one of the WAN device and the transmitting D2D wireless device is controlled to adjust the difference to meet the target difference.

摘要： The base stations in a coordinating set, i.e., CoMP set, implement distributed V-MIMO processing to decode uplink signals transmitted from multiple user terminals over the same time and frequency resources. Each base station uses the extrinsic information received from its coordinating base stations to facilitate demodulation and decoding. In the event that one of the base stations successfully decodes an uplink signal, it may provide the decoded data to the other coordinating base stations in the coordinating set. In this case, the coordinating base stations do not need to decode the uplink signal. Even if the uplink signal is not successfully decoded, the demodulated data received from the coordinating base station increases the likelihood of successfully decoding uplink signal in the next iteration of a HARQ process.

摘要： A base station node (BS) of a heterogeneous radio access network comprises a terminal locator (34) and a scheduler (36). The terminal locator (34) obtains an indication of location of a wireless terminal (30) in a cell served by the base station (BS), e.g., whether the wireless terminal (30) is in a center region (M) or an edge region (E) for the cell served by the base station node (BS). The scheduler (36) uses the indication of location to assign to the wireless terminal (30) a frequency of a frequency bandwidth usable by the heterogeneous radio access network. The scheduler (36) assigns a frequency from a partitioned portion of the frequency bandwidth if the cell served by the base station node is a micro cell and the wireless terminal is in an edge region of a micro cell. The scheduler (36) also assigns a frequency of the frequency bandwidth if the cell served by the base station node is a micro cell and the wireless terminal is in a center portion of the micro cell.
