Abstract: One or more packets to be transmitted to or from a user equipment (UE) device are determined to have a particular packet length, e.g., based on a vocoder to be used for a voice over Long Term Evolution (VoLTE) call. An initial modulation and coding scheme (MCS) is selected for transmission of the packets based on channel conditions. The initial MCS is replaced by an alternative MCS having a lower efficiency than the initial MCS in response to a determination that the alternative MCS would require the same number of resource blocks to transmit a packet having the particular packet length as the initial MCS. One or more resource blocks are allocated for transmission of the one or more packets having the particular packet length using the alternative MCS. Indications of the allocated one or more resource blocks and the alternative MCS are transmitted to the UE.

Abstract: Disclosed are methods and systems for managing allocation of air interface resources to a relay user equipment device (relay-UE) that provides wireless backhaul connectivity for a relay base station (relay-BS). In particular, a base station may serve the relay-UE and may make a determination that the relay-UE is positioned within an indoor environment rather than within an outdoor environment. While serving the relay-UE, the base station may manage allocation of air interface resources to the relay-UE and may do so based at least on the determination that the relay-UE is positioned within an indoor environment rather than within an outdoor environment.

Abstract: A method and system for controlling application of MU-MIMO. The disclosure provides for considering the quantity of data buffered for transmission over the air between the base station and each of various UEs, and selecting UEs to be subject to MU-MIMO service based on the quantity of data buffered. For example, a base station could prefer application of MU-MIMO for UEs that have more data buffered for transmission than other UEs. Or the base station could condition application of MU-MIMO to a pair of UEs on a determination that each UE of the pair has at least a threshold quantity of data buffered for transmission.

Abstract: A method and system to help facilitate efficient use of frequency spectrum. A base station will provide service on two carriers that partially overlap with each other in frequency. To facilitate this, the base station could shift the frame timing of one carrier in relation to the other carrier, so as to minimize or avoid overlap of the carriers' downlink control channels. Further, the base station could control service on each carrier in a manner that helps avoid resource conflicts within the overlapping frequency region.

Abstract: When a UE is served by a first RAN and engages in signaling via the first RAN with a second RAN for the second RAN serve the UE with a call (e.g., in a circuit-switched fallback process), the second RAN will determine a speed of movement of the UE and will decide based on the speed of movement whether to provide the UE with a second-RAN traffic channel assignment in addition to providing the UE with an indication of second-RAN coverage in which the call will be served. For instance, if the UE is moving at a threshold high rate of speed, then the entity will provide the UE with a second-RAN traffic channel assignment so as to help expedite the start of the call and to help avoid an issue where the UE may move out of the second-RAN coverage in which the call is to be served.

Abstract: Disclosed herein are methods and systems for selection of a coordinated multipoint (CoMP) mode for a relay base station, based on traffic load being experienced between the relay WCD and donor base station that provide the relay tunnel used by the relay base station for backhaul communication. An exemplary method involves the relay base station: (i) determining a load indication for a communication link between a relay wireless communication device (WCD) and a donor base station, (ii) using the load indication for the communication interface between the relay WCD and the donor base station as a basis for selecting a CoMP mode from a plurality of available CoMP modes; and (iii) providing wireless service in at least one coverage area according to the selected CoMP mode.

Abstract: Disclosed herein are methods and systems for dynamically controlling bearer quality-of-service (QoS) configuration. In an example arrangement, a wireless communication device (WCD) may have a first bearer and a second bearer with a base station, where the first bearer has a first set of one or more QoS parameters defining a first priority level for the base station scheduling communications on the first bearer, and the second bearer has a second set of one or more QoS parameters defining a second priority level for the base station scheduling communications on the second bearer, the second priority level being different from the first priority level. In this arrangement, an example method may involve detecting that the base station is threshold highly loaded, and responsive to the detecting, reconfiguring the second bearer to have the same QoS parameters as the first set of one or more QoS parameters.

Abstract: Disclosed is a method and system for selectively muting default downlink transmission of particular reference signals in order to reduce interference experienced by user equipment devices (UEs) receiving user data. In scheduling transmission of a downlink resource block (RB), a base station may select a particular transmission mode (TM) that does not require transmission of the particular reference signal. The base station may also determine that no condition exists that requires default transmission of the particular reference signal during a time interval allocated for transmission of the RB and on sub-carrier frequencies allocated to the RB. With particular TM selected and the absence of other requirements for default transmission of the particular reference signal, the base station can then mute transmission of the particular reference signal during transmission of the downlink RB. The base station may also coordinate scheduling with a neighboring base station to achieve further interference reduction.

Abstract: A method and system to help control air interface resource allocation. A base station monitors for each served UE a ratio of physical resource block (PRB) allocation to queued data, as a PRB/data ratio. The base station then detects that the PRB/data ratio of a first served UE has been threshold lower than the PRB/data ratio of each of a plurality of second served UEs, and the base station responsively selects at least one of the second UEs based on its modulation and coding scheme (MCS) being relatively high, and the base station limits PRB allocation to the selected UE to help reduce its PRB/data ratio and to thereby help achieve a level of fairness in PRB allocation.

Abstract: A method and system for scanning for target coverage in order of signal strength threshold. In a wireless communication system that defines a plurality of wireless coverage areas, a user equipment device (UE) may seek to select one of the coverage areas in which to operate. Each coverage area may have a respective downlink receive signal strength threshold (DSST) defining a minimum downlink receive signal strength for triggering UE selection of the coverage area. While operating in the wireless communication system, the UE may be arranged to rank-order the coverage areas in order of their respective DSSTs so as to define a sequence of the coverage areas. The UE may be arranged to then scan the coverage areas in order of the defined sequence, in search of a coverage area to select to operate in.
