摘要： Techniques are disclosed relating to acknowledgements and preemption indicators in the context of multiplexing different services on wireless physical layer frames. In some embodiments, transport blocks for a transmission are divided into code blocks and code block groups. Information indicating the division may be communicated between a base station and mobile device. In some embodiments, a preemption indicator is transmitted which indicates a portion of the transport block preempted by another data service, and the preemption indicator is specified at a different granularity than a code block group. In some embodiments, acknowledgement information is transmitted that indicates, for each code block group included in the transport block, whether the code block group was successfully decoded by the user device. In various embodiments, the disclosed techniques may facilitate preemption by a low-latency, high-reliability data service.

摘要： A device and method generates a hopping scheme for mobile stations of a wireless network. The method includes receiving a number of channels N of the wireless network. The method includes generating a shuffling matrix as a function of the number of channels N, each row of the shuffling matrix being indicative of a respective one of the mobile stations, each column of the shuffling matrix being indicative of a respective broadcast time of a discovery signal in a hopping scheme. The method includes generating the hopping scheme for the mobile stations in the channels as a function of the shuffling matrix. The hopping scheme maximizes an interval between two consecutive broadcast times that any two of the mobile stations are assigned to transmit discovery signals on adjacent channels.

摘要： In some embodiments, a user equipment device (UE) implements a method for discovering the presence of neighboring UEs using an on-demand discovery signal transmission technique. This discovery process may be performed to enable the UEs to perform peer-to-peer communications with each other, wherein peer-to-peer communications is defined as direct communication between the UEs without involving a base station. The UE may be configured to transmit a discovery request signal when it has moved greater than a threshold amount since transmission of a prior discovery request signal. The discovery request signal causes one or more neighboring UEs to each transmit a discovery signal in response, and also causes the UE which generated the discovery request signal to transmit its own discovery signal. The received discovery signal from each of the neighboring UEs is useable to discover, or detect the presence of, these neighboring UEs.

摘要： 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.

摘要： A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.

摘要： A user equipment (UE) transmits concurrent channel state information (CSI) processing capability information to a base station. The capability information can take various forms, and is intended to constrain the base station in the types of CSI requests that can be made to the UE. For example, the UE may indicate different CSI processing capabilities for intra-CC and inter-CC cases and/or for different codebook types. The UE may also specify supported combinations of codebook types for concurrent CSI reporting. The UE may also specify maximum resources or weighting factors for different codebook types. The UE may further restrict the rank information it provides and use a priority rule for “dropping” CSI report data due to payload size restrictions. The base station may direct, or the UE may implement, improved utilization of CSI resources that are shared for multiple concurrent CSI reports. Minimum time requirements for CSI reporting may also be relaxed.
