Abstract: Systems and methods are described for performing carrier aggregation based on subframe configuration. It may be determined that conditions for a wireless device in communication with an access node meet a carrier aggregation criteria, wherein the access node and wireless device communicate using a first subframe configuration. Signal information may be received from the wireless device comprising received signal levels for a plurality of candidate secondary carriers. Subframe configurations used by the candidate secondary carriers to communicate with wireless devices may be retrieved. One or more of the plurality of candidate secondary carriers may be selected based on the received signal level information and the retrieved subframe configurations. And carrier aggregation may be activated such that the one or more selected secondary carriers are used to transmit downlink data to the wireless device.

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: Disclosed is a method and system for compensating for excessive attenuation on an RF connection between a remote radio head (RRH) and an antenna of cell site. In an example configuration, in which first and second RF carriers of a cell site traverse different RF paths between respective RRHs and respective antenna, the second RF carrier may be subject to more attenuation than the first. Consequently, antenna transmission power of the second RF carrier may be below one or another threshold. For communication services to user equipment devices that involve both the first and second RF carriers, the diminished antenna transmission power of the second RF carrier may cause service degradation. In accordance with example embodiments, a controlling network entity may determine that the power is diminished, and responsively reallocate transmission power from an underutilized carrier to the second carrier, thereby boosting its transmission power and remediating service degradation.

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: In systems and methods of transporting data over an optical transport network, a first client signal and a second client signal are received at a network element of the optical transport network, each of the first client signal and the second client signal comprising a header and a data payload. An optical data unit is assembled comprising the first client signal and the second client signal in sequence, and the optical data unit is transmitted over the optical transport network. The first data payload and the second data payload may not be interleaved, and further, the first header and the second header may not be interleaved. The optical data unit can comprise the first client signal and the second client signal in a time sequence.

Abstract: According to aspects of the disclosure, a method and system are provided for managing signaling in a wireless communication network. In accordance with the disclosure, a base station serves a plurality of user equipment devices (UEs) via an air interface extending between the base station and the UEs. The base station also receives, on an uplink of the air interface, a report from each UE indicating channel state information (CSI). The base station periodically receives the report from each UE according to a CSI reporting rate specified by the base station for the UE. The base station may determine that a level of loading on the uplink is greater than a threshold load value. Responsive to such determination, the base station selects a subset of the plurality of UEs and reduces the CSI reporting rate for the selected subset of the plurality of UEs to reduce congestion on the uplink.

Abstract: A computing system will detect when a UE engaged in a voice call hands over from a lower frequency coverage area to a higher frequency coverage area where it is raining, and the computing system will responsively take action to help improve the UE's communication quality, in an effort to help minimize the extent to which voice call quality will degrade as a result of the transition to the higher frequency where it is raining. In particular, per the disclosure, the computing system could respond to this scenario by causing the target base station to use a more robust wireless transmission mode than the source base station was using to serve the UE.

Abstract: Disclosed is a method and system to help manage handover of a UE based on data buffering. In accordance with the disclosure, when a base station receives data destined for a UE, the base station may record the received data into a data buffer for temporary storage and retrieve the data at some later time to transmit the data to the UE. The base station may then determine, based at least in part on an amount of elapsed time from recording the data to retrieving the data, whether to invoke handover of the UE from being served by the base station to being served by a different, neighboring base station.

Abstract: Retransmission parameters are determined for a wireless device based on a desired retransmission success rate, that is, a probability that subsequent random access requests transmitted from the wireless device re-initiating a contention-based random access procedure with an access node will reach the access node. The retransmission parameters are determined based on at least a quality of service associated with the wireless device, a distance of the wireless device from the access node, and a cell load of the access node. The retransmission parameters include a retransmission power and a retransmission backoff window size. A product of the power and backoff window is scaled such that it can be equated with a retransmission success rate.

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 group delay, group delay variation, or insertion loss; (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.
