Abstract: Systems, methods, and computer-readable media are provided for determining a packet's round trip time (RTT) in a network. A system can receive information of a packet sent by a component of the network and further determine an expected acknowledgement (ACK) sequence number associated with the packet based upon received information of the packet. The system can receive information of a subsequent packet received by the component and determine an ACK sequence number and a receiving time of the subsequent packet. In response to determining that the ACK sequence number of the subsequent TCP packet matches the expected ACK sequence number, the system can determine a round trip time (RTT) of the packet based upon the received information of the packet and the received information of the subsequent packet.

Abstract: Systems and techniques for transmitting channel state information (CSI) include: receiving configuration information related to the CSI from a base station, the configuration information including information on a CSI-RS resource set; receiving a CSI-reference signal (CSI-RS) from the base station; and transmitting the CSI to the base station based on the configuration information and the CSI-RS. The CSI-RS resource set includes M CSI-RS resource groups; in addition, N CSI-RS resource groups (N?M) for reporting the CSI are determined from the M CSI-RS resource groups; the CSI includes N CSI sets generated based on a CSI-RS resource combination in the N CSI-RS resource groups. To generate an n-th (1?n?N) CSI set, a specific CSI-RS resource in an n-th (1?n?N) CSI-RS resource group is used for channel measurement; and a specific CSI-RS resource in the remaining CSI-RS groups other than the n-th CSI-RS resource group is used for interference measurement.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications networks may support carrier aggregation such that a user equipment (UE) may operate on both a primary cell using a first frequency range and a secondary cell using a second frequency range. In some cases, a beam failure associated with one or more beams of the secondary cell may be identified by the UE, and a beam failure recovery procedure may be triggered. The UE may send a beam failure recovery request message in an uplink data field of a physical uplink control channel (PUCCH) message to a base station of the primary cell. In response to the beam failure recovery request message, the base station of the primary cell may transmit a response to the UE which includes beam failure mitigation information.

Abstract: An improved channel access mechanism provides collision avoidance improves throughput. A communications device, e.g. an end node in a long range wireless communications system, determines that data is to be transmitted and performs a channel activity detection operation to determine if a communications channel is busy or idle. In response to determining that the channel is busy, the communications device determines a wait time based on a random number and a number of times a busy channel has been detected since determining that data is to be transmitted. The communications device uses the determined wait time in determining when to transmit.

Abstract: This disclosure provides systems, methods, and apparatuses for a beam-based channel access countdown procedure. In one aspect, a channel sensing beam may be permitted to include one or more transmit beams and, thus, may differ from a transmit beam that is to be used for a transmission. As such, defining a manner in which a channel access countdown procedure is performed is desirable. Some aspects described herein provide techniques and apparatus for a beam-based channel access countdown procedure. In some aspects, the systems, methods, and apparatuses described herein provide a beam-based channel access countdown procedure that allows a single channel sensing beam, including multiple transmit beams, to be utilized in association with determining channel availability for the multiple transmit beams, thereby improving performance of beam-based directional transmissions.

Abstract: Example embodiments of the present disclosure relate to reporting beam failure. A terminal device performs beam failure detection on a first number of serving cells configured for the terminal device. The terminal device determines information to at least indicate respective results of the beam failure detection on a second number of serving cells among the first number of serving cells, where the second number is smaller than the first number. The determined information is transmitted by the terminal device to a network device serving the terminal device using a resource allocated for the terminal device. Based on the information, the network device determines an overall result of the beam failure detection performed on the first number of serving cells.

Abstract: Automatic load-balancing techniques in a network device are used to select, from a multipath group, a path to assign to a flow based on observed state attributes such as path state(s), device state(s), port state(s), or queue state(s) of the paths. A mapping of the path previously assigned to a flow or group of flows (e.g., on account of having then been optimal in view of the observed state attributes) is maintained, for example, in a table. So long as the flow(s) are active and the path is still valid, the mapped path is selected for subsequent data units belonging to the flow(s), which may, among other effects, avoid or reduce packet re-ordering. However, if the flow(s) go idle, or if the mapped path fails, a new optimal path may be assigned to the flow(s) from the multipath group.

The UE may transmit, by an upper layer of the UE to an application of the UE, information to cause an indication of the second RAT to be displayed by the UE based at least in part on a bearer type associated with a link with the secondary cell and the indication that the RACH procedure with the secondary cell is successful. Numerous other aspects are provided.
