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: 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: 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.

Abstract: Disclosed are methods and systems for segregating user equipment devices (UEs) among carriers to help facilitate operation in lean-carrier mode in which a base station (BS) engages in a reduced extent of reference signaling on a particular carrier. In practice, the BS may operate in the lean-carrier mode when bearer data is not being communicated on the particular carrier. Given this arrangement, the BS may identify one or more UEs, of a plurality of UEs served by the BS, based on each UE communicating bearer data less frequently than a threshold frequency of bearer data communication. And the BS may serve just the identified UEs on the particular carrier, thereby increasing a probability of the BS operating in the lean-carrier mode.

Abstract: Coordinated multipoint (CoMP) can improve uplink service in cellular networks. However, uplink CoMP can also burden an access network, such as by increasing processing loads at base stations and/or increasing traffic on backhaul links between base stations. Accordingly, exemplary methods and systems help to dynamically select an uplink CoMP mode for a user equipment (UE) based on various factors, such as whether the UE is located at a border cell, whether or not carrier aggregation is being utilized for downlink communications with the UE, and/or whether or not the UE is a heavy data user, among other possible factors.

Abstract: When a base station is serving a user equipment device (UE) that tunes away from the base station during recurring tune-away periods, the base station will determine that the base station did not receive a communication expected to be received at a particular time from the UE. Based on the determining, the base station will estimate a first tune-away period of the UE's recurring tune-away periods to be a time period that encompasses the particular time. And based on the estimated first tune-away period, the base station will estimate times of subsequent tune-away periods. The base station will then configure itself such that it avoids communicating with the UE during the estimated times of the subsequent tune-away periods.

Abstract: A method and system for controlling handover of a WCD based on the WCD's operating temperature. In an example implementation, a determination is made that the WCD's operating temperature is threshold high, and that determination is used as a basis to trigger handover of the WCD to another coverage system, such as to another carrier frequency or to another base station coverage area. Further, in another example implementation, a determination is made that the WCD's operating temperature is threshold low (e.g., is not threshold high), and that determination is used as a basis to trigger handover of the WCD to another coverage system, such as back to the WCD's initially serving coverage system.

Abstract: A method and corresponding system to help improve handoff of a wireless communication device from a first network to a particular second network. The first network may maintain data that includes operational parameters of each of a plurality of second networks, such as networks that provide coverage in the same market area as the first wireless network. When the first network receives from a wireless communication device an indication that the device has detected coverage of a particular one of the second networks, the first network may then provide the device with the corresponding set of operational parameters for the detected second network.

Abstract: Disclosed is a method and system to help ensure contention-free response to a paging message. As disclosed, when a base station transmits a paging message for receipt by a UE, the base station includes in the paging message a contention-free random-access preamble useable by the UE to engage in contention-free random access in response to the paging message. The UE thus receives the paging message and responsively engages in a contention-free random access process with the base station, to establish a radio-link-layer connection between the UE and the base station.
