Abstract: Certain aspects of the present disclosure relate to techniques for assigning resources for common reference signal (CRS) transmissions from user equipment (UE) relays. Aspects of the present disclosure provide techniques to use minimum possible resources for transmission of CRS in an attempt to reduce interference, reduce power consumption while providing appropriate reference for channel measurement and demodulation. In an aspect, a wireless node (e.g., a UE relay station) may determine resources for transmission of CRS in a subframe based, at least in part, on a type of one or more channels to be transmitted in the subframe, and may transmit the CRS using the determined resources.

Abstract: A routing platform for routing 4G and 5G mobile data traffic in a mobile core networks implementing Option-3 of 5G Non-Standalone deployment. The routing platform captures S6a Diameter messages sent between a Mobility Management Entity (MME) and a Home Subscriber Server (HSS) and examines the captured messages to determine whether a user equipment (UE) is configured for a 5G data connection. The routing platform intercepts a GTP Create-Session-Request message sent from a Serving Gateway (SGW) and determines whether the GTP message is associated with the UE previously determined to be configured for a 5G data connection. If the GTP message is associated with the UE configured for a 5G data connection, the GTP message is either sent to a dedicated 5G Packet Network Data Gateway (PGW) or the GTP message is modified so that a single PGW handling both 4G and 5G traffic can establish a 5G session for the UE.

Abstract: A method of maintaining a proper forbidden tracking area identifier (TAI) list is proposed. A UE receives a service area list comprising one or more allowed tracking areas. The service area list may be carried by a configuration update command. UE compares if any of the allowed tracking area having a matching TAI in the forbidden TAI list. Accordingly, UE removes any allowed tracking areas having a matching TAI from the forbidden TAI list. In one embodiment, UE sends a REGISTRATION REQUEST message to initiate a registration procedure. In response, UE receives a REGISTRATION ACCEPT message, which may also carry a service area list. UE may remove the allowed tracking area having a matching TAI from the forbidden TAI list. However, if UE is registered for emergency services, then UE shall not remove the allowed tracking area from the forbidden TAI list.

Abstract: Techniques for transmitting reference signals (RSs) having respective signal patterns in the coding chain to improve performance of multiple input, multiple output (MIMO) communication systems are presented. For downlink transmissions, an RS management component (RSMC) of a network node can determine a first resource element (RE) pattern for RSs of a first cell and a second RE pattern for RSs of a second cell in the time, frequency, or code domain RSMC can utilize an adaptive interleaver in the coding chain to improve performance of MIMO systems. RSMC can facilitate configuring user equipment (UE) about the interleaver at the RE domain or as part of virtual resource block (VRB)-to-physical resource block (PRB) domain. RSMC can thereby reduce interference on RSs from other co-channel RSs, thereby improving channel estimation performance for channel-state-information estimation and data detection by the UE, and achieving significant gains in link and system throughputs.

Abstract: A user equipment (UE) for wireless communication is configured to perform bandwidth part (BWP) switching operation in response to receiving a system information change indication. The UE receives the system information change indication via a currently active BWP in a BCCH modification period. The system information change indication notifies the UE that contents of system information have been changed. The UE switches from the currently active BWP to an initial active BWP to receive the changed contents of system information which are required for the UE. The UE receives the changed contents of system information via the initial active BWP in a next BCCH modification period that immediately follows the BCCH modification period. The UE updates the system information according to the changed contents.

Abstract: Systems, methods, and computer-readable media for reducing latency in TCP connections that utilize loss insensitive congestion control mechanisms. In some examples, packet arrival times for one or more TCP packets of a TCP connection are analyzed and based on the analysis, it is determined whether the packet arrival times are constantly spaced over a period of time. Whether a TCP control mechanism for the TCP connection is loss insensitive is identified based on whether the packet arrival times are constantly spaced over time. If it is determined that the TCP control mechanism is loss insensitive, then a total number of acknowledgement packets transmitted during the TCP connection and associated with transmission of the one or more TCP packets in the TCP connection is reduced.
