    摘要： Systems and methods relating to an unacknowledged connection release in a cellular communications network are disclosed. In some embodiments, a method of operation of a base station in a cellular communications network comprises sending a connection release message to a wireless device that is in an Out-of-Sync (OOS) state and releasing a connection with the wireless device without receiving, from the wireless device, an acknowledgement of receipt of the connection release message. In this manner, signaling overhead for releasing the connection of the wireless device that is in OOS state is substantially reduced.

    摘要： To relieve signaling congestion, UEs (30) having delay-tolerant data are moved more rapidly to the non UL synchronized state, freeing up PUCCH resources for users that have not indicated a delay-tolerance. In one embodiment, a resource conservative mode is defined for a UE (30) having delay-tolerant data (e.g., from a “background” app); otherwise, the UE (30) assumes a default mode. In one embodiment, the network sends the UE a pair of first and a second values (or indices to them) for a Time Alignment Timer, TAT (56, 66) in the UE (30). The first value—which is typically smaller than the second value—is used by the UE (30) in the resource conservative mode when the user data plane is internally concluded as being delay-tolerant or has already been confirmed to be delay-tolerant; the second value is used otherwise (i.e., in default mode). In the resource conservative mode, the shorter TAT value moves the UE from PUCCH more rapidly, and the UE (30) uses random access for infrequent scheduling requests. In the default mode, the UE (30) retains PUCCH and has low latency for scheduling requests. The network may preconfigure the pair of TAT values. The mechanism is furthermore capable of achieving a synchronized start of a TAT value, and also stopping any TAT (56, 66) that is running.

    摘要： Systems and methods related to scheduling for a cluster of cells controlled by a base station of a cellular communications network are disclosed. In some embodiments, a method of operation of a base station in a cellular communications network to provide scheduling for a cluster of cells controlled by the base station is provided. In some embodiments, the method of operation of the base station comprises identifying a first set of Radio Access Bearers (RABs) for cluster scheduling for a Transmit Time Interval (TTI) and a second set of RABs for individual cell scheduling for the TTI, where the first set of RABs and the second set of RABs are non-over-lapping sets. The method further includes performing cluster scheduling for the first set of RABs for the TTI and performing individual cell scheduling for the second set of RABs for the TTI.
