Abstract: A system, method and non-transitory computer readable media for optimizing input data for an ML model associated with a communications network. In one implementation, example ML model(s) may be trained using a modified dataset obtained for a plurality of cellular aggregation units (CAUs) of the RAN infrastructure(s), wherein the modified dataset is derived from data collected for individual CAUs over a data collection period with respect to a plurality of KPI variables. The modified data set is optimized by replacement of null values of variables with corresponding modal values of the variables. The trained ML model may be used for predicting one or more KPIs based on a set of test data associated with the RAN infrastructure(s).

Abstract: A method of operating a wireless terminal communicating with a base station over a wireless channel may include determining whether the wireless terminal is in an edge area or an interior area of coverage of the base station. Responsive to determining that the wireless terminal is in an edge area of coverage of the base station, a transmit diversity communications rank indicator may be selected to select diversity communications over the wireless channel between the wireless terminal and the base station. Related wireless terminals are also discussed.

Abstract: Upon receiving a particular data unit by a receiving layer of a wireless device, it is detected that a previous data unit earlier in sequence to the particular data unit has not yet been received by the receiving layer. A timer is started in response to the detecting, where the timer has a time-out period that is variable dependent upon a parameter associated with receipt of the particular data unit. Upon expiration of the timer based on the timeout period, the receiving layer generates an error indication.

Abstract: A method and apparatus for controlling a Network Load Balancing (NLB) algorithm that balances a traffic load between multiple downlink (DL) sectors in a cellular telecommunication network. A Connection Integrity Preservation (CIP) algorithm, which runs on top of the NLB algorithm in the Radio Network Controller/Base Station Controller (RNC/BSC), minimizes the risk of degrading network performance due to NLB offload decisions. The CIP algorithm may override an NLB offload decision, for example, if there have been too many offload failures, there are no target DL sectors available to acquire an offloaded Access Terminal (AT), or the offloaded AT is not acquired within a threshold time period. The CIP algorithm ensures required metrics are collected, and minimizes the impact on RNC/BSC processing due to Routing Update messages needed to make offload decisions. The invention enables the NLB algorithm to realize its potential without negative side-effects.

Abstract: A method, apparatus, and radio receiver system for canceling multi-user interference in a single-carrier radio communication system. A front-end receiver such as a RAKE receiver receives a radio signal formatted in a sequence of frames, and outputs a plurality of user signals. A processing selector selects on a frame-by-frame basis, either a first signal processing chain that serially decodes and removes the interference contributions of the user signals, or a second signal processing chain that simultaneously decodes and removes the interference contributions of the user signals in parallel. The processing selector may select the first signal processing chain when the number of user signals is greater than or equal to a threshold value, and may select the second signal processing chain when the number of user signals is less than the threshold value.

Abstract: A UE of a spread spectrum wireless telecommunications system includes a network interface unit which receives multiple path energies of a wireless signal. The UE includes a rake receiver in communication with the network interface unit. The UE includes an equalizer in communication with the network interface unit, either the rake receiver or the equalizer processes the signal based on a predetermined criteria. A method of maintaining performance of a user equipment (UE) in a spread spectrum wireless telecommunications system includes the steps of receiving multiple path energies of a wireless signal at a network interface unit of the UE. There is the step of processing the signal with either a rake receiver of the UE in communication with the network interface unit or an equalizer of the UE in communication with the network interface unit based on a predetermined criteria.

Abstract: Multiple antennas at the transmitter and receiver increase the capacity in a wireless communication system. Received signal quality can be enhanced through diversity by transmitting the same symbol on multiple antennas. Data rate can be increased through multiplexing by transmitting different symbols on the transmitting antennas. Operating in one particular mode only is generally not suitable. Choosing diversity or multiplexing by taking into account the location of a user can enhance both throughput and reliability.

Abstract: A method, apparatus, and radio receiver system for canceling multi-user interference in a single-carrier radio communication system. A front-end receiver such as a RAKE receiver receives a radio signal formatted in a sequence of frames, and outputs a plurality of user signals. An ordering unit determines for a current frame, an order in which to decode and remove the interference contributions of the plurality of user signals. The order may be based on a list of user signals sorted in the order of descending signal-to-interference-plus-noise ratio (SINR), modified by the success or failure of attempts to decode each user signal. A frame calculator determines a coherence time, which is used to calculate the number of subsequent frames in which the user signals are decoded in the determined order.

Abstract: A communication device includes a decoder that sequentially decodes sub-packets of a first packet that contain redundant traffic information. The decoder identifies a first sequence location where it successfully decoded one of the sub-packets of the first packet to output the traffic information. The decoder then sequentially decodes sub-packets of a second packet starting at a second sequence location that is determined in response to the first sequence location. Related methods, user equipment node, and radio access network nodes are also disclosed.
