Abstract: A method and system for selecting carrier frequencies to use as a user equipment device's (UE's) primary component carrier (PCell) and secondary component carrier (SCell) for carrier aggregation service, based on consideration of the type of content that will be transmitted to or from the UE. A base station that is arranged to operate on a plurality of carrier frequencies may determine a type of content that will be communicated between the base station and a UE being served by the base station. Based on the determined type of content, the base station may select a first carrier frequency of the plurality to use as a PCell and may further select a second carrier frequency of the plurality to use as an SCell. The base station may then provide the UE with carrier aggregation service concurrently on the PCell and SCell.

Abstract: Disclosed is method and apparatus to help reduce PRACH interference. In accordance with the disclosure, when a first base station determines that there is a threshold level of interference from a second base station, the first base station transmits to the second base station a directive that causes the second base station to reduce PUSCH transmission in PUSCH resources that are coincident in frequency with the first base station's PRACH. In a scenario where two base stations provide overlapping coverage and operate on the same frequency as each other, and where coverage of the second base station may interfere with coverage of the first base station, this process may thereby help to minimize or eliminate interference that PUSCH communication in the second base station's coverage area would have on PRACH communication in the first base station's coverage area.

Abstract: Disclosed is a method and system for reducing the load on a downlink control channel of a given carrier of a plurality of carriers in a coverage area. As disclosed, a base station may determine that the downlink control channel of the given carrier is threshold loaded. In response to this determination, the base station may then (a) identify a particular subset of the UEs that are currently designated for DCI transmission on the downlink control channel of the given carrier and then (b) take action to de-designate the identified subset of UEs for DCI transmission on the given carrier and instead designate the identified subset of UEs for DCI transmission only on one or more other carriers in the coverage area.

Abstract: Coordinated multipoint (CoMP) may involve coordination between multiple sectors to receive and/or process a given user equipment's uplink signal. Embodiments herein may help to intelligently select the particular sectors that should coordinate to provide uplink CoMP, based on the types of applications being served in sectors that are candidates to provide uplink CoMP. For example, a base station serving a primary sector in an CoMP group that includes two or more candidates from which to select a secondary sector sectors for uplink CoMP, may evaluate the application being served by traffic flows in these candidates, in an effort to select secondary sectors having lower-priority traffic flows.

Abstract: Data identifying a plurality of wireless coverage areas in a region may be obtained. The data may identify geographic locations of the wireless coverage areas. Possibly based on the data, the wireless coverage areas may be arranged into a plurality of mutually exclusive tracking area groups. Each of the tracking area groups may include multiple wireless coverage areas and may be identified by respective unique tracking area identifiers. The tracking area groups may form a geographically-defined sequence across the region. A numerical sequence of wireless coverage area identifiers may be assigned to the wireless coverage areas in the region, one wireless coverage area identifier per wireless coverage area. The wireless coverage areas of the tracking area groups may be provisioned to use the assigned wireless coverage area identifiers.

Abstract: A method and system for controlling application of TTI bundling on a carrier on which an access node provides service, the carrier defining air-interface resources. An example method includes detecting that at least a predefined threshold number of devices of a predefined class (e.g., IoT devices) are connected with the access node on the carrier. Further, the example method includes, responsive to the detecting that at least the predefined threshold number of devices of the predefined class are connected with the access node on the carrier, proactively reserving a portion of the air-interface resources for use to serve communications between the access node and the devices of the predefined class and, in view of the proactive reserving of the portion of the air-interface resources, imposing a reduction in the application of the TTI bundling by the access node on the carrier.

Abstract: A method and system for controlling operation of a first access node that supports operation according to a first radio access technology (RAT) but does not support dual-connectivity operation according to the first RAT and a second RAT. A controller detects a high extent of occurrences of dual-connectivity-capable user equipment devices (UEs) being connected with the first access node when the dual-connectivity-capable UEs could instead connect with a second access node that supports the dual-connectivity operation. And in response, the controller suppresses coverage of the first access node, such as by reducing a maximum signal delay that the first access node applies for determining whether to accept random-access requests from UEs and/or (ii) reducing reference-signal transmission power of the first access node.

Abstract: A method and system for managing carriers on which a base station provides service to a user equipment device (UE), based on consideration of latency. A base station that is arranged to operate on a plurality of carriers may, while serving a UE on a set of one or more carriers of the plurality, select, from at least two other carriers of the plurality, an additional carrier to add to the set of one or more carriers on which the base station serves the UE, and may make the selection based a latency on the selected carrier. In response to selecting the additional carrier, the base station may add the selected carrier to the set of one or more carriers on which the base station serves the UE, and may then serve the UE on the set of one or more carriers including the selected carrier.
