Abstract: User equipment aggregates connections in at least one of a first unlicensed frequency band and a second unlicensed frequency band with a connection in a licensed frequency band to form a wireless backhaul connection to the user equipment. The user equipment selectively allocates a third unlicensed frequency band to a tethering connection.

Abstract: A user equipment determines a set of licensed and unlicensed frequency bands that are available for wireless communication. The user equipment selects a first subset of the set as targets for a handover involving at least one unlicensed frequency band and transmits information indicating the first subset. A base station receives information indicating a first subset of a set of licensed and unlicensed frequency bands. The first subset are targets for a handover of user equipment involving at least one unlicensed frequency band. The base station selects a second subset based on the first subset and transmits information indicating the second subset.

Abstract: Policy control and charging functionality in a network receives information indicating tariffs for a call session associated with a user equipment. The policy control and charging functionality defines, based on the information indicating the tariffs, a policy governing allocation of one or more licensed frequency bands and one or more unlicensed frequency bands to the call session. The policy and control charging functionality transmits the policy to a base station associated with the user equipment.

Abstract: A base station receives a charging policy indicating data usage tariffs for licensed and unlicensed frequency bands. The base station selectively allocates one or more of the licensed or unlicensed frequency bands to user equipment based on the data usage tariffs. A network charging system transmits a charging policy indicating data usage tariffs for licensed and unlicensed frequency bands. The network charging system receives a message including charging parameters for data usage by one or more of the licensed or unlicensed frequency bands that are selectively allocated based on the charging policy.

Abstract: Mobile units are handed over from LTE to carrier grade WiFi. The LTE can be licensed (LTE-L) or unlicensed (LTE-U). Charging mechanisms for co-located and integrated WiFi are also provided. When an LTE-U capable mobile unit moves into the LTE-U coverage area of a small cell, the mobile unit can use the unlicensed spectrum for a data session, thereby effectively increasing the data capacity of the network. When the mobile unit moves within the carrier grade Wi-Fi coverage area of the small cell, the small cell can handover the entire data session to the carrier grade Wi-Fi access point, thereby freeing up LTE system resources to provide data services to other mobile units.

Abstract: Nodes in a wireless communication system can mitigate interference in unlicensed frequency bands by coordinating downlink transmissions. The nodes may negotiate, based on messages exchanged over an interface between a first node and at least one second node, time intervals for downlink transmissions by the first node and the at least one second node over a channel of an unlicensed frequency band in response to the at least one second node transmitting over the channel of the unlicensed frequency band.

Abstract: In one embodiment, a message is sent from the wireless network to a user equipment having a variable rate vocoder. The message defines transport block sizes for the user equipment to select from in making uplink transmissions if the user equipment is permitted to vary a packet size for uplink transmission. A scheduling grant is sent to the user equipment, and the scheduling grant includes an indicator indicating that the user equipment is permitted to vary the packet size for uplink transmissions by selecting a transport block size from among the defined transport block sizes.

Abstract: The present invention provides a method of determining handoff parameters. One embodiment of the method includes determining values of a hysteresis for a handoff from a serving cell, one or more pairwise offset values for hand off between the serving cell and one or more neighbor cells, and one or more times-to-trigger (TTTs) for hand off between the serving cell and the neighbor cell(s). The values may be determined So that hand off is triggered beyond a first distance from the serving cell selected to avoid ping-ponging and within a second distance from the serving cell selected so that a mobile unit moving at a selected velocity does not travel beyond a third distance within the TTT.

Abstract: To address the need for new interference cancellation techniques that are able to deliver adequate performance but with reduced processing requirements, various embodiments are described. In some embodiments, a receiving device demodulates and decodes (101) at least one first-group user from a multi-user input signal. This multi-user input signal includes at least one first-group user and at least one second-group user, the first-group users having a shorter transmission time interval (TTI) than the second-group users. The receiving device reconstructs (102) an interference signal for each of the first-group users that were successfully decoded and subtracts (103) each interference signal from the multi-user input signal to generate an interference-canceled signal. The receiving device then demodulates and decodes (104) at least one second-group user using this interference-canceled signal.
