Abstract: A base station configures a TDD carrier to have a first TDD configuration for serving of a first UE and to have a second TDD configuration for serving of a second UE concurrently with the serving of the first UE. Such configuring causes the second UE to engage in an uplink communication in at least one subframe in which the first UE engages in a downlink communication, which could lead to interference issues. Therefore, the base station causes the second UE to apply uplink beamforming, so as to help minimize interference resulting from the second UE engaging in the uplink communication in the at least one subframe in which the first UE engages in the downlink communication.

Abstract: A method and system to help minimize communication latency. When data is to be transmitted from a transmitting entity to a receiving entity, the transmission will be scheduled to occur in a time interval that selected based on a consideration of the delay-sensitivity of the data and based on a HARQ delay associated with the selected time interval. For instance, if the data is particularly delay-sensitive, then the transmission could be scheduled to occur in a time interval that is selected based on the time interval having a relatively low associated HARQ delay, so as to help reduce the overall delay of the communication. Whereas, if the data is not particularly delay-sensitive, then the transmission could be scheduled to occur in a time interval that has a relatively high associated HARQ delay.

Abstract: Disclosed is a method and system for use of DCN-ID data as a basis for service configuration and differentiation. A UE may be provisioned with a DCN-ID that correlates with a service plan to which the UE subscribes, and the UE may include the DCN-ID in an attach request that the UE sends to a NB. The NB may then map the included DCN-ID to a service configuration for the UE and take action to configure service for the UE accordingly. In an example implementation, the service configuration could include a quantity of secondary NBs to be added for concurrent service of the UE, a set of one or more DCNs in which the UE should be connected, and a set of one or more application-layer services to be provided for the UE.

Abstract: A method and system to help manage reference-signal transmission power. A base station's reference-signal transmission power will be adjusted based on consideration of the coverage quality of one or more WCDs that are located at or near a mid-point between the base station and an adjacent other base station. In particular, if a threshold extent of coverage quality reports for the base station's reference signal received at or near the mid-point are threshold low, then the serving base station could responsively increment its reference-signal transmission power and/or responsively cause the adjacent base station to decrement its reference-signal transmission power. Whereas, if a threshold extent of such coverage quality reports are threshold high, then the serving base station could responsively decrement its reference-signal transmission power and/or responsively cause the adjacent base station to increment its reference signal transmission power.
