Abstract: Embodiments disclosed herein provide techniques to selectively distribute Precision Time Protocol (PTP) data in a network. The network can include multiple different network devices (e.g., switches) connected to form a network architecture (e.g., a spine/leaf architecture). Rather than distributing the PTP data (e.g., PTP timestamps) through all the network devices in order to synchronize local clocks to a global, master clock, the embodiments herein describe an out-of-band distribution network which selectively distributes the PTP data to select network devices in the network.

Abstract: Various aspects described herein relate to communicating in a wireless network. A transmission time interval (TTI) for an uplink control channel transmission within a subframe is determined, wherein the TTI comprises of a number of symbols which are a subset of a plurality of symbols in the subframe. Uplink control data can be transmitted over the uplink control channel during the TTI.

Abstract: A base station and mobile device (UE) may coordinate transmission of reference signals and reception of corresponding channel state information (CSI) reports. If a periodic reference signal is scheduled for transmission outside the on-duration period of the UE, even if the reference signal corresponds to a periodic CSI report scheduled to be transmitted by the UE during the on-duration period, the base station may not transmit the periodic reference signal, thereby allowing the UE not to prematurely exit a low-power state. The base station may instead transmit an aperiodic reference signal at a specified point in time later than the scheduled transmission of the periodic reference signal. The UE may receive the aperiodic reference signal and either transmit the periodic CSI report or an aperiodic CSI report in response, depending on how close to the start of the on-duration period the transmission of the periodic CSI report is scheduled.

Abstract: An electronic device is provided for use in a NAN cluster. The electronic device includes Wi-Fi communication circuitry; a memory that stores instructions; and a processor that executes the instructions to, while the electronic device operates as a master of the NAN cluster based on a first master preference, control the Wi-Fi communication circuitry to transmit discovery signals outside of discovery windows (DWs), based on a determination that a state of the processor is switched from a wake-up state to a sleep state, change control information for the NAN cluster, wherein the changed control information for the NAN cluster includes data regarding a second master preference that is distinct from the first master preference, and provide the changed control information to the Wi-Fi communication circuitry. The Wi-Fi communication circuitry, while the processor is switched to the sleep state, transmits the changed control information for the NAN cluster.

Abstract: The described techniques provide for devices (e.g., a base station, a user equipment (UE)) to determine control channel processing limits for control channels for a CA configuration for a plurality of component carriers (CCs) with mixed numerology and synchronicities (e.g., CCs may have different transmission time interval (TTI) durations, subcarrier spacings, or frame timing). The devices may determine control channel processing limits for numerology groups or synchronization groups of the CA configuration based on a UE capability for processing control channels for a number of CCs, which may be allocated proportionally according to number of cells, allocated equally, or allocated using weighting factors assigned to synchronization or numerology groups. A base station may establish a CA configuration or control channel configuration according to the capability, or may ensure that a per-numerology restraint is not exceeded by determining a combined processing parameter.

Abstract: A user device provides, to a network, information associated with the user device, and receives, from the network, a multi-bit network indication that indicates access technologies, services, and network capabilities provided by the network. The user device determines whether the user device is in a home network or a visited network based on the multi-bit network indication. The user device passes bits of the multi-bit network indication to an upper layer when the user device is in the home network or passes a portion of the bits of the multi-bit network indication to the upper layer when the user device is in the visited network. The user device receives a selection of one of the access technologies, the services, or the network capabilities, and receives, from the network, the one of the access technologies, the services, or the network capabilities for the user device based on the selection.

Abstract: Disclosed are a wireless base station, wireless terminal, and channel signal formation method that can prevent the quality of downstream assignment control data from degrading, while preventing the number of blind determinations from increasing on the wireless terminal on the receiving side of the downstream control channel signal. In a base station (100), a control unit (101) and a data size regulation unit (103) control the data size of downstream assignment control data and upstream assignment control data contained in the PDCCH signal based on the communication format used between the base station (100) and a terminal (200), the number of antennas (M) (nonnegative number) on the base station (100), the number of antennas (N) (nonnegative number) on the terminal (200), the bandwidth of the downstream band, and the bandwidth of the upstream band.

Abstract: Methods and techniques are described for efficiently supporting periodic and triggered location services for a user equipment (UE) in a Fifth Generation wireless network. A serving core network (CN) node, such as an AMF, receives a request for periodic or triggered location for the UE from another CN entity, such as a GMLC, and transfers the request to a location server, such as an LMF, which initiates and establishes the periodic and triggered location session with the UE. The serving CN node then releases all resources for the location request. The UE monitors for periodic or trigger events and reports each event to a location server which forwards an event report, optionally containing a UE location, to an external client via a CN entity, such as GMLC. The event reporting can be efficient because a serving CN node is not materially involved.

Abstract: Certain aspects of the present disclosure provide techniques for service request (SR) prioritization for intra-UE (user equipment) ultra-reliable low-latency communication (URLLC) service and enhanced mobile broadband (eMBB) service multiplexing.

The method includes determining one or more transmission resources for one or more service requests (SRs) for a first type of service and/or a second type of service. The method includes determining one or more priority levels associated with the one or more transmission resources. The method includes transmitting the one or more SRs using the determined one or more transmission resources based on the associated priority levels.

Abstract: Mechanisms of CCA status reporting and NAV distribution for coordinated transmissions in a multi-AP WLAN. A coordinator AP may broadcast a RTS frame to a set of coordinated APs, which allow the coordinated APs with a CCA clear status to set a protected period in a CST frame to silence the associated non-AP STAs. The coordinator AP also polls the coordinated APs to have them individually report their CCA statuses as well as additional information used for transmission coordination. In some embodiments, a status report from a coordinated AP may integrate the protected period setting and the CCA clean status indication, and therefore the coordinator AP just needs to poll for such a report without using RTS/CTS exchange. A coordinated AP may set a protected period to end at the complete transmission of a coordination frame. The coordination frame may specify the remaining TXOP duration information.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may implement polar coding to generate codewords for transmission, for example, in a physical broadcast channel (PBCH). The base station may identify a subset of the bandwidth allocated for PBCH transmission (e.g., corresponding to a bandwidth for a synchronization signal), and may assign sub-channels to information bits based on the identified bandwidth subset. The base station may generate a codeword based on the assigned sub-channels, and may map a subset of encoded bits for the codeword to the subset of the bandwidth such that the subset of encoded bits includes bits corresponding to the assigned subchannels for the information bits. A user equipment (UE) may receive the encoded bits in the subset of the bandwidth, and may decode the subset of encoded bits to determine the information bits.

Abstract: Apparatus and methods for discovery, synchronization and operation of network components. In one embodiment, the network comprises a passive optical network (PON), and the components being synchronized include an enhanced OLT (eOLT) and one or more enhanced ONUs (eONUs). The eOLT is configured in one variant to utilize control protocol messaging (such as those used in the MPCP or Multi Point Control Protocol) to communicate particular synchronization parameters and durations to the eONU(s), whether individually or via multicast/broadcast. The synchronization parameter and durations are selected to optimize discovery and synchronization of the eONU(s) with the eOLT, and also optimize (subsequent) normal operation, in one implementation through selection of synchronization patterns which enable most efficient AGC determination, clock recovery (CDR), SBD, and EBD identification.

Abstract: A reorder queue device for a multipath receiver includes a reorder queue and a reorder queue controller. The reorder queue is configured to queue data packets numbered in sequence which are received over multiple paths of a multipath channel. The reorder queue controller is configured to reorder the data packets in the reorder queue according to a reorder criterion, wherein the reorder criterion is based on at least one of the following: path-specific sequence numbering of the data packets, overall sequence number comparison across the multiple paths, or path-specific characteristics of the multiple paths. The data packets are numbered in a path-specific sequence and in an overall specific sequence. The reorder queue controller is configured to detect a packet loss on a specific path based on determining the overall sequence numbers and/or the path-specific sequence numbers of at least two packets of the specific path.
