摘要:
The present application describes embodiments of methods for network assisted interference cancellation. Some embodiments of the method include broadcasting control information from a first cell over a common control channel. The control information is associated with a data channel transmitted by the first cell and the control information is usable by user equipment served by a second cell to mitigate interference caused by the data channel at the user equipment.

At least one example embodiment discloses a system including a network element configured to transmit downlink control channel information to a user equipment (UE) using a first bandwidth, the first bandwidth being at least a portion of a long term evolution (LTE) bandwidth, transmit a preamble to the UE using a second bandwidth, the second bandwidth being a bandwidth excluding the LTE bandwidth, and the preamble indicating a scheduled data transmission, and transmit data to the UE using the second bandwidth in accordance with the downlink control channel information and the preamble.

At least one example embodiment discloses a system including a network element configured to transmit at least first downlink control information and second downlink control information to a first user equipment (UE) being served by a serving cell, the first downlink control information associated with a first identification and the second downlink control information associated with a second identification, and the second downlink control information corresponding to at least one interfering source.
摘要:
Base stations can exchange information indicating that the base stations are transmitting (or going to transmit) downlink signals over one or more unlicensed frequency bands. For example, a first indication that a first base station is reserving a first subset of a plurality of unlicensed frequency bands for downlink transmission can be transmitted over one or more interfaces between the first base station and one or more second base stations. The one or more second base stations can then refrain from transmitting potentially interfering downlink transmissions over the first subset of the plurality of unlicensed frequency bands. Information identifying the first subset may be stored by the one or more second base stations.

A method of controlling communication between a first network node and a second network node in a multi-carrier wireless communications system, network nodes and a computer program product are disclosed. The method of controlling communication between a first network node and a second network node in a multicarrier wireless communications system in which a predetermined set of a plurality of carriers are utilized to support communication between the first network node and the second network node, the predetermined set of the plurality of carriers comprising a primary carrier and at least one secondary carrier, comprises the steps of: determining an occurrence of an event requiring a change in the primary carrier; indicating to a third network node that a physical layer instruction is to be transmitted between said first network node and the second network node; and transmitting a physical layer instruction between the first network node and the second network node, the physical layer instruction encoding reselection information to cause the second network node to select a different carrier from the plurality of carriers as a new primary carrier. By sending the instruction using the layer one or physical layer, the speed at which the instruction can be transmitted between the network nodes is vastly increased, which enables fast switching to occur, thereby preventing a loss of communications between the network nodes. By indicating to a third network node that a physical layer instruction is to be transmitted between the first network node and the second network node, maintenance of synchronization is simplified and unpredictable network behavior is minimized.
摘要:
In one example embodiment, the machine type communication device includes a processor configured to determine whether a first uplink control channel and a second uplink control channel will collide during a transmission from the machine type communication device to the communication network, and adjust the transmission of the second uplink control channel relative to the first uplink control channel if the processor determines that the first and second control channels will collide.
摘要:
Methods are disclosed for efficient scheduling of frequency resources (for example, subband and/or PRB locations) and/or identification of Modulation & Coding Scheme (MCS) for a UE in a wireless communication system. The UE may comprise, without limitation, a Low Complexity Machine Type Communication (LC-MTC) device. Frequency resource allocations (e.g., subband and/or PRB) are selected from among one or more subsets of available resource allocations (i.e., fewer than the entirety of possible resource allocations) within a frequency space, which allows the resource allocations to be specified with a relatively small number of DCI bits.
