Abstract: A method for triggering cell transition in an uplink power limited condition is disclosed. The method can include a wireless communication device determining that the wireless communication device is experiencing an uplink power limited condition; deriving a modified downlink channel quality measurement by adjusting a measured downlink channel quality to indicate a lower downlink channel quality than the measured downlink channel quality; generating a measurement report including the modified downlink channel quality measurement; and sending the measurement report to the serving cell to trigger transition of the wireless communication device from the serving cell to a second cell.

Abstract: Apparatus and methods for implementing “intelligent” receive diversity management in e.g., a mobile device. In one implementation, the mobile device includes an LTE-enabled UE, and the intelligent diversity management includes selectively disabling receive diversity (RxD) in that device upon meeting a plurality of criteria including (i) a capacity criterion, and (ii) a connectivity criterion. In one variant, the capacity criterion includes ensuring that an achievable data rate associated with a single Rx (receive) chain is comparable to that with RxD.

Abstract: One or more processors are configured to execute instructions that cause a UE to perform operations. The operations include offloading a task to a first network node. The operations include determining a computation requirement forecast, wherein the computation requirement forecast indicates a computation requirement of the task at an upcoming time. The operations include transmitting the computation requirement forecast to the first network node. The operations include performing a handover procedure from the first network node to a second network node.

Abstract: Apparatuses, systems, and methods for split-bearer enhancements during dual-connectivity operation, e.g., in 5G NR systems and beyond (e.g., NextG, 6G, and so forth). A base station may set up a split-bearer for a UE operating in dual-connectivity and connected to the base station and one or more corresponding base stations, including setting up a ratio of a split of data to be delivered to the UE via the base station and the one or more corresponding base stations. The base station may transmit, based on the ratio of the split, a first portion of the data destined for the UE to the UE and a second portion of the data destined for the UE to the one or more corresponding base stations. The base station may adjust, based on one or more split-bearer quality reports received from the UE, the ratio of the split.

Abstract: A method for managing a QoE for a UE in a communications network is provided. The method includes determining, based at least on data received in a communications session, one or more parameters affecting the QoE. The method includes determining weights corresponding to the one or more parameters. The method includes computing an expected QoE for the UE based on the determined weights corresponding to the one or more parameters. The method includes determining that the expected QoE satisfies a threshold. The method includes transmitting, to one or more network nodes in the communications network, the determined weights corresponding to the one or more parameters. The method also includes adjusting the communications session at the UE.

Abstract: A user equipment (UE) device may perform random access to a base station in the context where propagation delay between the base station and the UE device is large. The UE device randomly selects a random access preamble from an available set of preambles. The UE device selects a time slot for transmission of the random access preamble based on a configured correspondence between allowable time slots and subsets of the available set. The UE device transmits the random access preamble to a base station in the selected time slot, with timing advance to compensate for a common delay. Thus, the base station, knowing the configured correspondence, is able to determine the time slot in which the random access preamble was transmitted. The UE device receives a random access response that has been addressed with a Random Access Radio Network Temporary Identifier (RA-RNTI).

Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A base station (BS) may receive from a user equipment (UE) a first buffer status report (BSR) indicating an amount of uplink data buffered by the UE for transmission to the BS, and may subsequently receive a first BSR update message indicating that an additional amount of uplink data has been buffered by the UE subsequent to transmission of the first BSR. The first BSR update message may be received prior to expiration of a timer authorizing transmission of a second BSR following the first BSR. In response, the BS may allocate resources for transmission to the UE, based on the first BSR and the first BSR update message. The BS may provide an uplink grant identifying the allocated resources.

Abstract: A user equipment (UE) device may communicate according to a new device category satisfying specified QoS (quality of service) requirements while also satisfying specified link budget requirements, and/or additional optimization requirements. The UE device may communicate with a cellular base station according to a first mode of operation associated with the new device category, and may switch to communicating with the cellular base station according to a second mode of operation associated with a second (pre-existing) device category in response to the link budget requirements exceeding a specified value and the quality of service requirements not being sensitive. The UE device may also switch to communicating with the cellular base station according to a third mode of operation associated with a third (pre-existing) device type in response to the link budget requirement not exceeding the specified value, or the QoS requirements being sensitive and a downlink throughput requirement exceeding a specified throughput value.
