摘要:
Communication systems, such as the long term evolution (LTE) advanced (LTE-A) of the third generation partnership project (3 GPP) may benefit from various enhancements. These enhancements can include LTE time division duplex (TDD) enhancements for traffic adaptation and uplink (UL)-downlink (DL) interference management. A method can include determining whether a first cell, in a network including the first cell and a second cell, autonomously selects a time division duplex uplink-downlink configuration. The method can also include sending an authority indicator to a base station of the first cell regarding a determination of whether the first cell is to autonomously select the configuration.

A method for neighbor cell assisted TDD configurations is described. The method includes receiving, from a serving cell, a first configuration. The first configuration is a cell specific configuration which indicates a first set of individual configurations for each of a plurality of SFs. A second configuration is received from the serving cell. The second configuration is a UE specific configuration which indicates a second set of individual configurations for each of the plurality of SFs. The method includes determining whether a given SF is configured differently in the first configuration than in the second configuration. In response to determining that the given SF is configured differently in the first configuration than in the second configuration, the method also includes communicating, with a neighbor cell, in the given SF as configured in the second configuration. Apparatus and computer readable media are also described.

Methods, corresponding apparatuses, and computer program products for mobility control in a heterogeneous network are provided. The method comprises sending, by a source local area base station (e.g., a source access point), a handover request for handing over a user equipment to a target local area base station (e.g., a target access point), wherein the source and target local area base stations are connected with a same wide area base station and the user equipment is connected with the same wide area base station via the source local area base station. The method also comprises handing over, based on a handover request acknowledgement from the target local area base station, the user equipment to the target local area base station for continuing with at least one of an ongoing local area service and an ongoing wide area service without changing security keys of the same wide area base station. With the claimed inventions, the handover latency and service continuity during the inter-AP mobility would be efficiently improved in a secure manner.

According to an example embodiment of this application, a method may include determining a distance from a network element; and assigning at least one of a downlink resource or an uplink resource to the network element based at least in part on the determined distance, wherein the assigned resource is used for both a downlink and an uplink communication of the network element.

A method, apparatus and computer program product are provided to support traffic offloading in a manner that relies upon,a wireless access point having a co-located local gateway (L-GW), but that does not require each access point to have a co-located L-GW. In the context of a method, the traffic offloading capabilities of at least one other access point is initially determined. The method may also cause a tunnel to be established with another access point with a co-located L-GW having traffic offloading capabilities. Further, the method cause communications with a network to be conducted via the tunnel established with the another access point so as to utilize the traffic offloading capabilities of the another access point.

In one non-limiting, exemplary embodiment, a method includes: receiving radio resource control signaling with a user equipment, wherein the radio resource control signaling is indicative of at least one frequency sub-band to be measured by the user equipment for a particular cell in a manner transparent to at least one of an interference control scheme and a handover scheme implemented for the cell; performing at least one measurement of the at least one frequency sub-band; and reporting information descriptive of the at least one measurement.

A white space entity reserves spectrum in white space from a reservation system. Consequently, the white space entity may utilize television bands that are unused at a specified time period and geo-location in order to support different services such as wireless audio transmission, networking, video surveillance, and video conferencing. The white space entity requests reservation of spectrum resources from the reservation system by sending a reservation request. The request includes request parameters that may include geo-location, model number or manufacture code number, priority of entity, reservation time period, and maximum power level. The reservation system consequently verifies the request from the priority of the white space entity and the availability of white space spectrum for the desired time period. The white space entity then extracts confirmation parameters from a reservation confirmation message and subsequently transmits on white spectrum in accordance with the parameters.

There is a pattern for downlink almost blank sub frames ABSFs for a first network node (e.g., macro eNB) operating in a first component carrier (e.g., PCell). For a user equipment UE operating with the first network node on the first component carrier and also with a second network node on the second component carrier, then either or both of the following are imposed. The UE is scheduled on the first component carrier such that no uplinic control information UCI from the UE is scheduled for any uplink subframe in the first component carrier which maps from any of the ABSFs; and the UE is scheduled on the second component carrier such that UCI from the UE is scheduled only for an uplinic subframe in the second component carrier which maps from any of the ABSFs. By example, the UCI includes either/or ACKs and NACKs corresponding to data sent downlink to the UE.
