Abstract: The described techniques relate to methods, systems, devices, and apparatuses that support narrowband reference signal (NRS) configuration for non-anchor carriers. Generally, the described techniques provide for increasing the length of an NRS scrambling sequence for non-anchor carriers. For example, the NRS scrambling sequence initialization equation may be a function of system frame number. A base station may transmit to a user equipment (UE) a non-anchor carrier configuration indicating that the NRS scrambling sequence is extended with respect to other NRS scrambling sequences. For example, the non-anchor carrier configuration may indicate the scrambling sequence initialization for the NRS. In some examples, the length of the NRS scrambling sequence is increased by extending the number of possible initializations. The base station and UE may communicate based on the extended length of the NRS scrambling sequence for non-anchor carriers of the NRS.

Abstract: Methods, systems, and devices for wireless communications are described to enable a base station to configure additional reference signals, which may be referred to as configured reference signals, to include in a transmission to a user equipment (UE). The UE may transmit a report to the base station, indicating a UE capability for supporting configured reference signals, and the base station may configure a pattern for the configured reference signals. The base station may transmit an indication of the pattern to the UE, where the indication may include one or more characteristics associated with the configured reference signals. The base station may transmit the configured reference signals to the UE according to the pattern, along with one or more baseline reference signals, within an associated transmission. The UE may use the configured reference signals and the baseline reference signals to receive a transmission from the base station.

Abstract: Systems and methods are disclosed for enhancing network performance by using modified traffic control (e.g., rate limiting and/or scheduling) techniques to control a rate of packet (e.g., data packet) traffic to a queue scheduled by a Quality of Service (QoS) engine for reading and transmission. In particular, the QoS engine schedules packets using estimated packet sizes before an actual packet size is known by a direct memory access (DMA) engine coupled to the QoS engine. The QoS engine subsequently compensates for discrepancies between the estimated packet sizes and actual packet sizes (e.g., when the DMA engine has received an actual packet size of the scheduled packet). Using these modified traffic control techniques that leverage estimating packet sizes may reduce and/or eliminate latency introduced due to determining actual packet sizes.

Abstract: A method for improving service reliability includes deciding, by a session function entity in a network, to initiate establishment of at least two transmission paths between a terminal and the user plane function entity, and instructing the terminal or the user plane function entity to transmit same data on the at least two paths. The user plane function allocates, based on a notification of the session function entity, user plane resources to the at least two transmission paths, and transmits the same data with the terminal on the at least two transmission paths. A core network initiates the establishment of the at least two transmission paths to the terminal. Two access devices may independently establish the at least two transmission paths.

Abstract: A user equipment (UE) is described. The user equipment includes receiving circuitry configured to receive a radio resource control (RRC) signal comprising first information. The receiving circuity is also configured to monitor a physical downlink control channel (PDCCH). The user equipment also includes transmitting circuitry configured to perform semi-persistent channel state information (SP-CSI) reporting. The user equipment also includes processing circuitry configured to drop the SP-CSI reporting based on that the SP-CSI reporting is being performed without multiplexing with an uplink shared channel (UL-SCH) and the SP-CSI reporting overlaps in time with a positive scheduling request (SR) transmission. The processing circuitry is also configured to drop the SP-CSI reporting based on that the SP-CSI reporting overlaps in time with an UL-SCH transmission in one symbol.

Abstract: Methods, systems, and devices for sidelink wireless communications are described in which multiple resource pools are available for sidelink communications. Each resource pool may include a set of frequency domain resources, a set of time domain resources, and one or more subsets of available spatial resources. A transmitting user equipment (UE) may select a first spatial resource of a first resource pool for the sidelink communication, and determine a demodulation reference signal (DMRS) pattern for the sidelink communications based on the selected first spatial resource of the first resource pool. The transmitting UE may then transmit the sidelink communication and DMRS to a receiving UE using the first spatial resource of the first resource pool. The receiving UE may identify the DMRS and use the DMRS to demodulate the sidelink communication of the transmitting UE.

Abstract: Data packet retransmission by a radio link control (RLC) protocol entity of a transmit end is described herein. The retransmission includes sending a target sequence number and a first data packet to a MAC entity of the transmit end and recording a quantity of times the target sequence number is transmitted to the MAC entity of the transmit end at an RLC layer. In accordance with receiving the target sequence number and a negative acknowledgement that are sent by the MAC entity, obtaining the RLC layer transmission count corresponding to the target sequence number. In accordance with determining the RLC layer transmission count is less than an RLC layer transmission threshold, sending a retransmission instruction based on the first data packet to the MAC entity. In accordance with a retransmission condition at the RLC layer being met, the RLC entity of the transmit end triggers retransmission at the RLC layer.

Abstract: A communication method, a base station, a radio communication node, and a user equipment are provided. A base station determines first resource configuration information, where the first resource configuration information is used for indicating N radio resource sets that are used when N radio communication nodes separately perform communication with a user equipment UE, and the radio resource includes a time domain resource and/or a frequency domain resource. The base station sends the first resource configuration information to the UE, where the UE communicates with a corresponding transmission point by using respective radio resource sets of transmission points, and the respective radio resource sets of the transmission points do not intersect. Therefore, a base station does not need to schedule a radio resource, thereby lowering a delay requirement on a backhaul link and eliminating interference.

Abstract: A system on a chip (SOC) is configured to support multiple time domains within a time-sensitive networking (TSN) environment. TSN extends Ethernet networks to support a deterministic and high-availability communication on Layer 2 (data link layer of open system interconnect “OSI” model) for time coordinated capabilities such as industrial automation and control applications. Processors in a system may have an application time domain separate from the communication time domain. In addition, each type time domain may also have multiple potential time masters to drive synchronization for fault tolerance. The SoC supports multiple time domains driven by different time masters and graceful time master switching. Timing masters may be switched at run-time in case of a failure in the system. Software drives the SoC to establish communication paths through a sync router to facilitate communication between time providers and time consumers. Multiple time sources are supported.
