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: 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: During a communication session, a filter in the RAN may filter signals sent over the communication pathway. When the filter filters signals sent over communication pathway, it may also cause some filter loss in the signals. The amount of the filter loss may vary as a function of frequency. Before the start of a communication session, the RAN may determine a filter loss for a given frequency. Because a higher filter loss indicates the RAN will transmit (or receive) a weaker signal, it may be undesirable to transmit signals to WCDs that are located a far distance from the RAN with frequencies having high filter losses. Thus, once the RAN has determined a filter loss for a given frequency, the RAN may reserve the given frequency for use in communication between the RAN and at least one WCD based on a distance between the WCD and the RAN.

Abstract translation: 在通信会话期间，RAN中的过滤器可以过滤通过通信路径发送的信号。 当滤波器过滤通过通信路径发送的信号时，它也可能导致信号中的一些滤波器损耗。 滤波器损耗的量可以随着频率的变化而变化。 在通信会话开始之前，RAN可以确定给定频率的滤波器损耗。 由于较高的滤波器损耗表示RAN将发送（或接收）更弱的信号，因此可能不希望将信号发送到与RAN的距离远的WCD，频率具有较高的滤波器损耗。 因此，一旦RAN已经确定给定频率的滤波器损耗，RAN可以基于WCD和RAN之间的距离来保留用于RAN与至少一个WCD之间的通信中的给定频率。
