Abstract: According to the present disclosure, a base station may be configured to serve a user equipment device (UE) over two or more beams using different modulation and coding schemes (MCSs) in response to determining that another base station is concurrently serving another UE at nearly the same location. For instance, a first base station may initially serve a first UE over two beams using the same MCS on both beams. The first base station may then determine that a second base station is serving a second UE at nearly the same location. And in response, the first base station may then change the MCS on at least one of the two beams so that the first base station then serves the first UE using different MCSs on the two beams. Serving the first UE with different MCSs concurrently on multiple beams may help to improve the first UE's reception.

Abstract: Disclosed herein are systems and methods for dynamically adjusting drop-timer thresholds based on loading. An embodiment takes the form of a method carried out by at least one network entity in a communication system that also includes a radio access network (RAN) providing wireless service to access terminals in a coverage area, in part by enforcing a drop timer having an associated start threshold and an associated stop threshold. The method includes determining a current level of load in the coverage area, and further includes adjusting one or both of the start threshold and the stop threshold based at least in part on the determined current level of load in the coverage area.

Abstract: A method and corresponding system is provided to help mitigate the potential quality-of-service degradation associated with fast-moving UEs operating in a network that provides higher-bandwidth frequency channels in some but not all wireless coverage sectors. In accordance with the method, a base station may evaluate a UE's current speed and, when that speed exceeds a threshold speed, the base station may instruct the UE to register on a low-bandwidth channel rather than a higher-bandwidth channel. Registering for service on a low-bandwidth channel instead of a higher-bandwidth channel may help ensure that the UE maintains a consistent quality of service as the UE moves from coverage area to coverage area. Further, the base station may also query nearby base stations to determine whether there exists a sufficient number of base stations that operate on higher-bandwidth channels. If so, the base station may instruct the UE to use a higher-bandwidth channel.
Abstract translation: 提供了一种方法和相应的系统，以帮助减轻与在一些但不是全部无线覆盖扇区中提供更高带宽频率信道的在网络中操作的快速移动UE相关联的潜在服务质量下降。 根据该方法，基站可以评估UE的当前速度，并且当该速度超过阈值速度时，基站可以指示UE在低带宽信道而不是较高带宽信道上注册。 在低带宽信道上注册服务而不是较高带宽信道可能有助于确保UE随着UE从覆盖区域移动到覆盖区域而保持一致的服务质量。 此外，基站还可以查询附近的基站，以确定是否存在在较高带宽信道上操作的足够数量的基站。 如果是，则基站可以指示UE使用较高带宽信道。

Abstract: Disclosed is a method and apparatus and system for managing frequency use in a system where multiple air interface protocols are in use. When a wireless communication device (WCD) is operating under a particular air interface protocol on a particular frequency channel, the WCD detects a threshold signal under another air interface protocol, and the WCD responsively transitions from operating under the particular air interface protocol on the particular frequency channel to operating under the particular air interface protocol on a different frequency channel. The method may thereby help to reduce likelihood of interference.

Abstract: A method and system for dynamically allocating backhaul bearer service based on network loading conditions to help use backhaul-network resources more efficiently. A RAN detects an event relating to bearer service establishment for a given application. Then the RAN identifies a standard bearer service for the given application, where the standard bearer service has a first quality of service. After detecting the event, the RAN determines that a load of the backhaul communication network does not exceed a load threshold. Then, based on the determination that the load of the backhaul communication network does not exceed the load threshold, the RAN selects a bearer service for the given application, where the selected bearer service has a second quality of service that is higher than the first quality of service. Next, the RAN causes the selected bearer service to be established.

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: In a wireless network comprising a plurality of carriers available for carrier aggregation transmissions between a base station and UE, the base station: (i) determines whether a requirement exists to transmit data between the UE and the base station via a carrier aggregation transmission; (ii) in response to determining that the carrier aggregation transmission requirement exists, selects a primary component carrier and one or more secondary component carriers from the plurality of carriers for the carrier aggregation transmission based on one or more of each carrier's receive power at the UE, transmit power at the base station, and frequency; (iii) allocates the selected primary and secondary component carriers to the carrier aggregation transmission; (iv) informs the UE of the allocation; and (v) executes the carrier aggregation transmission according to the allocation.

Abstract: Systems and methods for performing UE handover based on group delay variation include a base station (i) selecting a target neighbor sector from a plurality of neighbor sectors for the handover, where each neighbor sector has a group delay metric, and where the target neighbor sector is selected from the neighbor sectors based at least in part on each neighbor sector's group delay variation and (ii) initiating handover of the UE to the target neighbor sector. Some embodiments include creating a neighbor relations table (NRT) comprising at least some of the neighbor sectors, and prioritizing the NRT based on group delay and/or group delay variation. In some embodiments, selection of the target neighbor sector for the handover is additionally based on neighbor sector handover success rates and Reference Signal Receive Power (RSRP) values for neighbor sectors reported by the UE for which the handover is to be performed.

Abstract: A radio access network (RAN) determines whether transmission time interval (TTI) bundling is warranted for a wireless communication device (WCD) based on information contained in one or more reports from the WCD. The information may include a reference-signal value, such as a reference signal received power (RSRP) or a reference signal received quality (RSRQ), in a measurement report, an amount of data indicated in a buffer status report as being buffered by the WCD for transmission via one or more bearers in a bearer group, and a service class associated with the bearer group. If the RAN determines that TTI bundling is warranted for the WCD, the RAN may further select a TTI bundle size for the WCD. The RAN may select the TTI bundle size from among a plurality of values, which values may include a standard TTI bundle size and a smaller TTI bundle size.
