Techniques for improved wireless reliability are provided. Data is transmitted to a client device using a first set of retry parameters. It is determined that the client device is an augmented reality (AR) or virtual reality (VR) device, and a second set of retry parameters is determined, where the second set of retry parameters are more robust than the first set of retry parameters. Data is transmitted to the client device using the second set of retry parameters.

A first device includes a processor, a wireless communication device in data communication with the processor, and a hardware storage device in data communication with the processor. The hardware storage device includes instructions stored thereon that, when executed by the processor, causes the host device to compare a Quality of Server Subtype (QoS-Subtype) value to a matching rule of a policy table stored on the hardware storage device, determine a transmission policy based at least partially on the QoS-Subtype value, wherein the transmission policy includes a transmission rate with a modulation and coding scheme (MCS) index based at least partially on the QoS-Subtype, and transmit a transmission to a second device according to the transmission policy.

A user equipment (e.g., C-V2X user equipment) can receive a transmission from a network device of a mobile network and decode the transmission using a first forward error correction code. The user equipment can determine an attribute of the transmission to determine a condition of the communication channel. Based on the condition of the communication channel, the user equipment can facilitate transmitting feedback to the network device, wherein the feedback is forwarded through the mobile network to an application server device that selects a second forward error correction code based on the feedback. The second forward error correction code can be transmitted to, and received by, the user equipment. The user equipment can use the second forward error correction code to decode subsequent transmissions.

The invention relates to a method, apparatus and system for configuring control channels in a mobile communication network and a mobile station. In order to suggest another improved scheme for configuring control channels, in particular control channels related to the transmission of user data the invention suggests aligning the size of the control channel information of different formats to an equal number of coded control channel information bits and/or modulation symbols for each control channel. The control channels may comprise scheduling related control information. According to another aspect of the invention, the size of the control channel information is aligned by means of modulation and/or coding, however the control channel information is aligned to one out of a set of numbers of coded control channel information bits and/or modulation symbols for each control channel.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a first communication that includes information to facilitate selection and/or switching of carrier aggregation or multi-connectivity for a first cell group and a second cell group. The UE may receive, based at least in part on transmitting the first communication, a second communication that configures and/or switches carrier aggregation or multi-connectivity for the first cell group and the second cell group. Numerous other aspects are provided.

The described technology is generally directed towards scheduling, by a distributed unit, the injection of custom traffic (signals/data) into a radio unit communications path. The distributed unit coordinates with the radio unit to schedule and synchronize such custom traffic in unscheduled (physical resource block), such as interleaved with to live-air and non-live-air traffic. The radio unit can request the unscheduled physical resource blocks for custom traffic to be inserted by the radio unit. Alternatively, the distributed unit can inject the custom traffic in otherwise unscheduled physical resource blocks for sending to the radio unit. The custom traffic is configured to perform some action by the radio unit, such as to perform antenna calibration, to perform test and measurement operations to obtain performance data, and the like. Performance data can be used, for example, to modify operating parameters of the radio unit to improve performance of the radio unit.

A Quality of Experience (QoE) optimization system and method are provided. An electronic device inputs key performance indicators (KPIs) and system control parameters collected from a core network, a base station and a user equipment (UE) into a QoE optimization model. The QoE optimization model then optimizes the system control parameters based on the KPIs and a user QoE fed back from the UE to output optimized system control parameters. Furthermore, a strategy emulator controls at least one of a base station emulator and a UE emulator, so as to emulate the QoE optimization model using the at least one of the base station emulator and the UE emulator. Non-real-time optimization adjustments to the QoE optimization model are made based on the result of the emulation performed by the at least one of the base station emulator and the UE emulator.

A data packet for delivery to a user equipment can be inspected. Based on the inspecting, whether to use a robust downlink delivery can be determined. Based on the determining, a robust modulation coding scheme (MCS) for the data packet can be selected. The data packet can be transmitted utilizing the selected robust MCS. At least one of the inspecting, the determining, the selecting, and the transmitting is performed using at least one processor of at least one computing system.
