A method includes determining position information of a main transmission sink having a primary transmission path to a communications device and of at least one mirror transmission sink associated with the main transmission sink by at least one secondary transmission path between the main transmission sink and the communications device, estimating primary channels between the communications device and antennas of an antenna array of the main transmission sink and secondary channels between the communications device and antennas of an antenna array of the at least one mirror transmission sink, the estimating is at least partially based on the position information of the main transmission sink and the at least one mirror transmission sink and position information of the antennas in the antenna arrays, and instructing use of the estimated primary channels and the estimated secondary channels.


A system and method of subframe configuration in licensed-assisted access using long-term evolution (LAA-LTE) with carrier aggregation (CA). A wireless device such as an eNodeB (eNB) may transmit control information in a subframe from a secondary cell (SCell) in downlink control information (DCI) to a user equipment (UE). The SCell may operate in an unlicensed band. The control information may indicate at least one of a non-ending subframe in a data burst, an ending subframe, and a duration of the ending subframe. The duration may be one of a predefined number of orthogonal frequency-division multiplexing (OFDM) symbol durations, and the ending subframe may be a partial or full subframe. A partial ending subframe may use a time slot structure in a time division duplexing (TDD) scheme, e.g., downlink pilot time slots (DwPTS). The eNB may then transmit to the UE data in the subframe according to the control information.


A system and method for system and method for multiplexing control and data channels in a multiple input, multiple output (MIMO) communications system are provided. A method for transmitting control symbols and data symbols on multiple MIMO layers includes selecting a first set of codewords from N_(cw )codewords, distributing control symbols onto the first set of layers, placing data symbols of the first set of codewords onto the first set of layers, placing data symbols of the (N_(cw)-N_(cw1)) remaining codewords to remaining layers if N_(cw)>N_(cw1), and transmitting the multiple MIMO layers. The first set of codewords is associated with a first set of layers from the multiple MIMO layers, and the N_(cw )codewords are to be transmitted simultaneously and the first set of codewords comprises N_(cw1 )MIMO codewords, where N_(cw )and N_(cw1 )are integers greater than or equal to 1. The remaining layers are MIMO layers from the multiple MIMO layers not in the first set of layers.

A network node that provides egress fault protection for a primary egress node. The network node may receive a service label associated with an application from a primary egress node of a primary label switched path (LSP). The network node may use the service label to add a forwarding entry into a forwarding table associated with the primary egress node. Following a fault in the primary egress node, the network node may receive a data packet comprising an LSP label and the service label from a partial backup LSP. The network node may use the LSP label to locate the forwarding table associated with the primary egress node. The service label may be used to deliver the data packet to a destination node according to the forwarding table associated with the primary egress node.

A method includes allocating, by a communications controller, a first set of resource blocks to an enhanced physical downlink shared channel (ePDSCH), where the ePDSCH has a first starting point and allocating, by the communications controller, a second set of resource blocks to an enhanced physical downlink control channel (ePDCCH). The method also includes identifying, by the communications controller, a second starting point for the ePDSCH, where the second starting point for the ePDSCH is located within a legacy control region, where the first starting point of the ePDCCH is located within the legacy control region, and where the second starting point of the ePDSCH is different than the first starting point of the ePDCCH. Additionally, the method includes signaling, by the communications controller to a user equipment (UE) the second starting point and a number of the second set of resource blocks allocated to the ePDSCH.

System and Method for Content Encryption in a Key/Value Store System and method embodiments are provided for content encryption in a key/value store. The embodiments include encrypting both the key and value of client data blocks for storage so that the data can be retrieved reliability without compromising the key. An embodiment method includes obtaining a key from a data block comprising the key and a value, encrypting the key using a deterministic encryption algorithm with an encryption key to map the key to a cypher text in a one-to-one mapping, and encrypting the value using a second encryption algorithm to randomly map the value to a second cypher text. Encrypting both the key and the value provides more protection to the client data instead of encrypting only the value and leaving the key vulnerable without encryption. The encrypted key can also be protected from unauthorized access and from the owner of the database or the storage system.
