Abstract: Proposed is a method and apparatus for receiving UL data in a wireless LAN system. Particularly, a transmission apparatus transmits an NSRP trigger frame to a reception apparatus. The transmission apparatus receives an NSR control frame from the reception apparatus in response to the NSRP trigger frame. The NSR control frame includes an NAV value. When the NAV value is 0, the transmission apparatus transmits a trigger frame to the reception apparatus. The transmission apparatus receives UL data from the reception apparatus on the basis of the trigger frame.

Abstract: An apparatus and method are provided for receiving data by a first transceiver. The method includes receiving information for at least one transmission mode through higher layer signaling from a second transceiver; and receiving data on a first sub-frame based on a first demodulation reference signal (DMRS), if the at least one transmission mode is transmission mode 9 or transmission mode 10 and the first sub-frame is a multimedia broadcast multicast service single frequency network (MBSFN) sub-frame.

Abstract: The scheduling flexibility of CSI reference signals enables time and frequency synchronization using multiple non-zero CSI-RSs transmitted in the same subframe, or using CSI-RSs transmitted in the same subframe with other synchronization signals. Also, multiple synchronization signals may be scheduled in the same subframe to enable fine time and frequency synchronization without cell-specific reference signals.

Specifically, the present aspects include determining whether a gap length between a two-step random access channel (RACH) preamble transmission and a physical uplink shared channel (PUSCH) transmission satisfies a gap condition. The present aspects further include selecting a transmission procedure associated with the determined gap length for the PUSCH transmission. The present aspects further include performing the PUSCH transmission in accordance with the selected transmission procedure.

Abstract: This application describes apparatus and methods for using edge-computing to control resource distribution among access channels, such as a retail banking center. Edge-nodes may be configured to move a product display in response to detected or expected customer traffic flow in or near a retail location. Edge-nodes may be configured to redirect resources provided by a cloud computing environment to or away from the retail location. Based on customer traffic flow, edge-nodes may direct customers/resources to a retail location and ensure the retail location provides a predetermined quality of service.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support chained sidelink transmissions. A transmitting user equipment (UE) may send, to a receiving UE, sidelink control information (SCI) that reserves resources for transmission from the transmitting UE as well as reserves resources for a response transmission from the receiving UE. The receiving UE may respond with a transmission using the resources that were reserved in the SCI and without sending its own SCI to reserve resources for the response. The latency between the transmitting UE sending the first transmission and receiving a response from the receiving UE may be reduced, because the transmitting UE reserved the resources for itself and the receiving UE with the same SCI.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may interrupt a user equipment (UE) during transport block (TB) encoding. The UE may cancel transmission (e.g., suppress processing) of a TB based on the interruption, such that a first subset of code blocks is encoded and a second subset is unencoded. In some cases, the UE may receive a re-transmission request for a code block including cyclic redundancy check (CRC) bits for the TB, where the CRC bits are not prepared. In one example, the UE may modify the CRC bits (e.g., set them to a common value, drop them, etc.) to reduce processing time. In another example, the base station may request re-transmission of all preempted code blocks, supporting TB CRC calculation. In another example, the base station or UE may extend a processing timeline for the re-transmission to support TB CRC calculation.

Abstract: The present disclosure relates to a user equipment (UE) comprises a receiver, which receives reference signals from a serving base station on which the UE is camping, the serving base station controlling an unlicensed serving radio cell in which the UE is located. Processing circuitry of the UE monitors the reception of reference signals to determine a number of reference signals that are continuously missing. The processing circuitry determines to perform cell re-selection from the unlicensed serving radio cell on which the UE is camping to another radio cell that has a different frequency than the unlicensed serving radio cell, in case the determined number of reference signals that are continuously missing is above a threshold.

Abstract: In some embodiments, a method sets a threshold for utilization of a first table, wherein the utilization is based on layer 3 addresses and layer 2 addresses being stored in the first table. When a utilization of the first table does not meet the threshold, the method stores a layer 3 address in the first table. The first table uses a first type of lookup to determine a next hop address for the layer 3 addresses or the layer 2 addresses, and the first table also stores one or more layer 2 addresses. When the utilization of the first table meets the threshold, the method stores the layer 3 address in a second table where the second table uses a second type of lookup to determine the next hop address for layer 3 addresses.

Abstract: A user equipment has been allocated uplink resources, e.g. interlaced uplink channel resources, e.g. interlaced physical uplink shared channel (PUSCH) resources, and non-interlaced uplink channel resources. The UE receives cancellation indication (CI) information which rescinds the allocation for a portion of the previous granted resources. CI is communicated using different formats for resources which are in blocks and resources which are interlaced. The CI for the interlaced resources uses a more efficient format with less overhead to communicate frequency information corresponding to the cancellation for the interlaced channel.

In certain embodiments, these techniques include receiving, at a network device from a software-defined networking (SDN) controller, flow entries for installation into flow tables of the network device, where the flow entries are structured in a manner that assumes the flow tables can be looked-up serially by a packet processor of the network device, but where the flow tables are implemented using hardware lookup tables (e.g., TCAMs) that can only be looked-up in parallel by the packet processor. The techniques further include converting, by the network device, the received flow entries into a format that enables the packet processor to process ingress network traffic correctly using the flow entries, despite the packet processor's parallel lookup architecture, and installing the converted flow entries into the flow tables/hardware lookup tables.
