Abstract: A method and system for controlling how many carriers to aggregate together for carrier-aggregation service of a UE. A base station could take into account how many MIMO layers a UE would support respectively for each of various candidate quantities of carriers, and the base station could select the candidate quantity of carriers that would result in use of a highest aggregate total number of MIMO layers. Further, the selection could involve mapping UE-reported rank to a quantity of carriers, with the rank being inversely proportional to the selected quantity of carriers. The base station could then configure carrier-aggregation service of the UE with the selected quantity of carriers.

Abstract: Methods and systems disclosed herein can help to dynamically adjust the degree of or enable/disable concatenation of page messages, depending upon whether a user equipment is operating as a single radio LTE (SRLTE) device. An exemplary method involves a radio access network: (i) determining that a UE is configured to use a single radio system for both (a) data communication under a first air interface protocol, and (b) voice calls under a second air interface protocol that is different from the first air interface protocol, (ii) based at least in part on the determination, selecting a page-concatenation level to be used to page the first UE, and (iii) transmitting at least on page message to the UE according to the selected page-concatenation level.

Abstract: Disclosed is a method and system for dynamically adjusting modulation and encoding scheme (MCS) and transport block size (TBS) used for downlink transmissions from a base station (BS) to a user equipment device (UE) based on a frequency of retransmission requests from the UE. The BS may identify the UE as belonging to a first class of UEs designated as being capable of receiving data at a first data rate that is higher than a second data rate designated for UEs of a second class, for the same downlink channel quality reported by the UE. Based on the identification, the BS may select a MCS and TBS for the UE corresponding to the first data rate. Upon receiving more than a threshold number of retransmission requests from the UE, the BS may switch to using the second, lower data rate. The first and second classes could correspond to later and earlier technology generations, for example.

Abstract: A method and system for paging of a wireless client device (WCD). When a wireless communication system encounters a trigger to page a WCD, the system will identify the WCD's most recent serving base station (e.g., the WCD's currently registered base station, or the base station providing the WCD's currently registered coverage area) and will determine whether that base station is a relay base station or rather a non-relay base station. If the base station is a non-relay base station, then the system will provide the initial page of the WCD via just that base station (e.g., as in the zone based paging process discussed above). Whereas, if the base station is a relay base station, then the system will provide the initial (ordinal first) page of the WCD via both that base station and the donor base station that provides the relay base station's wireless backhaul connection.

Abstract: Methods and systems disclosed herein can help to dynamically adjust page transmission power, and in particular, the transmission power for quick paging bits, depending upon whether a user equipment (UE) is operating as a single radio LTE (SRLTE) device. An exemplary method involves an access network making a determination that a UE is configured to use a single radio system for (a) data communication under a first air interface protocol, and (b) voice calls under a second air interface protocol; and responsively initiating a process to set a transmission power used to page the first UE for a voice call under the second air interface protocol to a higher power level, as compared to a transmission power level utilized to page a second UE configured to use separate radio systems for data communication under the first air interface protocol and voice calls under the second air interface protocol.

Abstract: A method and system to control WCD handover. A first base station will request load information from a second base station, and, based at least in part on a result of that request, the first base station will control handover of the WCD. The first base station may decline to hand over the WCD to the second base station in response to determining that the first base station did not responsively receive load information from the second base station. Further, the first base station may determine a level of confidence in load information of the second base station based on whether the first base station received load information of the second base station and based on whether the first and second base stations are provided by the same vendor, and the first base station may then use that level of confidence as a basis to control handover of the WCD.

Abstract: A method of managing modulation for transmission of data in anticipation of handover. When a source base station is serving a UE and determines that the UE is going to hand over to a target base station, the source base station automatically transitions to transmit data to the UE with a low-order MCS selected without regard to CQIs reported by the UE, or at least to apply an MCS corresponding with a CQI lower than that reported by the UE. By applying a low-order MCS to transmit data to the UE, the source base station may increase the likelihood that the data will arrive successfully at the UE, as the low-order MCS may be more tolerant to noise than higher-order MCSs.

Abstract: Disclosed is a method and system to help manage latency and reduce unnecessary signaling in setup of fallback communications, such as circuit switched fallback calls for instance, by taking into account the load in various fallback coverage areas. When the load of a fallback coverage area is threshold high, signaling may pass to a serving network to cause that fallback coverage area to be filtered out of a list of fallback coverage areas that a base station of the serving network would provide to a served device, so as to help avoid having the device scan for coverage of that fallback coverage area.

Abstract: Disclosed herein is a method and corresponding system for managing communication in a first network, where the first network is interconnected with a fallback network. The first network may detect, when a user equipment device (UE) served by a base station of the first network seeks to initiate a voice call, the UE will transition from being served by the first network to be served by the fallback network in order to initiate the voice call directly via the fallback network rather than initiate the voice call via the first network. In response to detecting this, and further in response to the base station not supporting signaling between the UE and the fallback network, the first network may cause the UE to not transition to be served by the fallback network and to instead stay served by the base station.
