Abstract: The present invention is provides a method and apparatus for routing a data packet in a network. For each nearby device capable of routing the packet toward a further destination, an associated cost or utility is determined. The device with lowest cost or highest utility is selected and the packet is forwarded toward same. The selecting may use a comparator tree. The cost or utility may be associated with forwarding the data packet from the candidate device toward the further destination. The cost or utility may be based on a distance from candidate device to the further destination, and may be determined using a Haversine function or approximation thereof, or by computing an inner product of a first vector and a second vector originating at a center of Earth, the first vector directed toward the candidate device, the second vector directed toward the further destination.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support signaling an indication of a duration (for example, in UE capability information) for the UE to perform a beam switch (for example, to switch between different directional beams). Among other examples, base stations may be configured with a default value related to a duration for UEs to perform a beam switch. Thus, in an absence of the above signaling by the UE, base stations may identify a duration for UEs to perform a beam switch according to the configured default value. Additionally, base stations may allocate symbols between different physical channels (such as, downlink channels or uplink channels) related to directional communications. One or more symbols may be exclusive of or be part of resources related to the physical channels to provide improvements to beam switching for UEs.

Abstract: This application provides a method and an apparatus that are for transmitting data in a random access process. The method includes sending a message 1 to a network device. The method further includes receiving a message 2 sent by the network device, where the message 2 includes uplink grant information, where the uplink grant information includes first indication information, and where the first indication information is used to indicate a largest transport block size TBS allowed for a message 3. The method includes determining a target TBS in candidate TBSs based on the allowed largest TBS, where the target TBS is less than or equal to the allowed largest TBS. The method further includes sending the message 3 to the network device, where the message 3 includes uplink data transmitted based on the target TBS.

Abstract: A user equipment (UE) includes a receiver that receives, from a base station (BS), one or more Transmission Configuration Indication (TCI) states for Physical Downlink Control Channel (PDCCH) reception via Radio Resource Control (RRC) signaling and a Medium Access Control Control Element (MAC CE) activation command for one of the TCI states via a Physical Downlink Shared Channel (PDSCH). The UE further includes a transmitter that transmits, to the BS, a Hybrid Automatic Repeat reQuest (HARQ) for the MAC CE activation command in a slot and a processor that activates the one of the TCI states k slots after the slot where the transmitter transmits the HARQ. A value of the k indicates a number of slots.

Abstract: A user device performing communication with another user device by beamforming in a first frequency and a second frequency different from the first frequency is provided. The user device includes a receiving unit configured to receive a first sensing signal in the first frequency; a control unit configured to select a resource in the second frequency used for transmission, based on a resource location on a radio frame in which the first sensing signal is provided, or based on information, contained in the first sensing signal, indicating a resource location on a radio frame in the second frequency; and a transmitting unit configured to perform data transmission in the second frequency by using the selected resource.

Abstract: A data transmitting method, a data receiving method, a terminal device, and a network device are provided. The method includes: determining, by a terminal device, a target resource based on a time index and/or configuration information; and transmitting, by the terminal device, data to a network device on the target resource. The terminal device can control resource granularity of the target resource to meet transmission requirements of the terminal device, and can further avoid an actual data transmission process from occurring only on a same frequency domain resource and can further improve the frequency diversity gain in the non-slot transmission. In addition, randomness of interference can be enhanced as much as possible to avoid a same user from always or frequently being in conflict, so when a DMRS of the terminal device conflicts with that of other terminals, performance of user identification can be effectively improved.

Abstract: Embodiments discussed herein refer to systems, methods, and circuits for managing and establishing contactless communications lanes between two contactlessly coupled systems. A contactless communication lane can be formed for each coupled pair of contactless communication units existing in the two systems. A contactless communications interface can enable software-defined connectivity that manages use of the contactless communication data lanes to enable data communications according to a selected one of a plurality of communications interfaces. The contactless communications interface may serve as a protocol translator and virtualization layer for enabling higher level software such as an operating system of a first system to communicate with a second system without requiring interface protocol specific hardware and software. This advantageously simplifies hardware and software components needed to simultaneously service a multitude of interface protocols.

Abstract: Aspects herein generally relate to a system and/or a method for enforcing synchronization of WiFi users interacting with a common hierarchical multi-element VR/AR scene. The aspects can use Orthogonal Frequency Division Multiple Access (OFDMA) and trigger frames to synchronize parallel updates to different scene elements. Deep Packet Inspection (DPI) can be used to analyze standard VR/AR streaming formats to identify those VR scene elements that are to be synchronized. The result is a more immersive AR/VR experience for the users, who receive the same scene elements at the same time.

Abstract: An apparatus aborts a transmission of a first message of a first type of traffic in a first slot or sub-slot without resuming the transmission in the first slot or sub-slot. The apparatus then stores a payload of the first message. The apparatus later retransmits the payload in full in a second slot or sub-slot that is subsequent the first slot or sub-slot.

Abstract: In a wireless access node, a Protocol Data Convergence Protocol (PDCP) separates data into direct data and indirect data. The wireless access node wirelessly transfers the direct data to User Equipment (UE) and transfers the indirect data to a wireless support node. The wireless support node wirelessly transfers the indirect data to the UE. The PDCP estimates a transmission time difference between the direct data and the indirect data. The PDCP separates additional data into direct data and indirect data. The PDCP delays the additional direct and/or indirect data based on the time difference to synchronize delivery. The wireless access node wirelessly transfers the direct data to the UE and transfers the indirect data to the wireless support node. The wireless support node wirelessly transfers the indirect data to the UE.
