Abstract: Examples herein include apparatus and methods for overriding a media access control module acknowledgment and non-acknowledgment scheme. In one example, a codec module determines if an error-corrected packet is acceptable in response to the detection by the media access module of an uncorrectable error in a received packet, and overrides the media access control module to prevent a non-acknowledgment response from being sent when the error-corrected packet is acceptable.

Abstract: A carrier scheduling method and apparatus. The method comprises determining search spaces of downlink control channels corresponding to at least two first transmission time units on a first carrier, where the at least two first transmission time units are scheduled in one second transmission time unit on a second carrier, and the downlink control channels are in a one-to-one correspondence with the first transmission time units; and obtaining, in the search spaces, the downlink control channels corresponding to the at least two first transmission time units. In this application, a plurality of transmission time units on another carrier are scheduled in a cross-carrier manner, thereby improving transmission resource utilization.

Abstract: Example data transmission methods and apparatus are described. One example method includes obtaining at least two signature sequences used to perform multiple access for at least two to-be-sent data packets by a user equipment. The user equipment processes the at least two data packets by respectively using corresponding signature sequences, to obtain at least two transmit sequences. The user equipment sends the at least two transmit sequences to a network device on a same time-frequency resource. Then the network device obtains the at least two signature sequences used by the user equipment to send the at least two transmit sequences, and separately detects a corresponding transmit sequence based on each signature sequence, to obtain the at least two data packets. The user equipment can transmit a plurality of data packets on a same time-frequency resource in a same slot.

Abstract: Systems and methods are provided to allow configuration of network devices via a Bluetooth® (or other short range wireless) configuration network using a mesh network implementation. This configuration mesh network may represent a mesh network independent of any active wired or production network within an enterprise computer system. For security of a network infrastructure for the enterprise computer system, wired ports on network infrastructure devices may be disabled prior to configuration via the configuration mesh network. New devices may be physically but not communicatively connected to the production network (e.g., cables may be connected to disabled ports) and then configuration may be performed via the configuration mesh network to allow the new devices to become active (e.g., join with production devices) within the network infrastructure. Run-time configurations for production devices may also be maintained using a separate configuration mesh network.

Abstract: A message transmission method and device relating to the field of communications technologies is disclosed, so as to improve an anti-interference capability in message transmission. The method includes: generating, by a base station, a scrambling code according to a first time parameter; then scrambling a system message according to the scrambling code; and finally sending the scrambled system message to a terminal on a physical broadcast channel. In this technical solution, because the first time parameter has different values at at least two different moments, scrambling codes determined at the at least two corresponding different moments are different. Therefore, a possibility at which the base station uses a same scrambling code to scramble a same system message repeatedly in a time period is reduced, so that an anti-interference capability in system message transmission is improved.

Abstract: Network equipment receives, from User Equipment (UE), information indicative of each of multiple UE locations in a wireless communication network. For each location, a respective antenna beam direction for communications between the network equipment and a UE at each location is determined. A Machine Learning (ML) module is trained using each location as an ML module input and the respective antenna beam direction for each location as an ML module output. The trained ML module is then used to provide beam predictions based on UE location. Based on the current location of a UE, one or more antenna beam directions for communications between the network equipment and the UE at the current location are obtained from the ML module. The UE location is input to the ML module, and the antenna beam direction(s) are then obtained from the ML module output(s).

The processor includes instructions which, when executed by the processor, cause the processor to receive a system notification of a local area network on which the network communication device is communicating, communicate with a target gateway on the local area network through the network communication device if the target gateway is communicating on the local area network, and communicate with the target gateway through a wide area network through the network communication device if the target gateway is not communicating on the local area network.

Abstract: Techniques are described to provide a peephole optimization for processing traffic for lightweight protocols at lower layers by executing them inside a virtual switch rather than using the network stack of a host node. In one example, a method includes determining by forwarding logic of a virtual switch that a received packet is associated with a query for one of domain information or address information. Based on such a determination, the virtual switch determines whether the query is contained within a single Ethernet frame and is answerable. Based on a positive determination for both, the virtual switch determines whether a response to the query can be transmitted in a single packet within a single Ethernet frame. Based on a positive determination of a single packet response, a response packet for the query is formed and injected into the forwarding logic for the virtual switch for transmitting to a destination.

In some aspects, the first wireless node may synchronize a timing configuration of the first wireless node to at least one of the second wireless node or a third wireless node based at least in part on the round-trip time timing advance indicator. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for per-station punctured transmissions. A wireless local area network (WLAN) device may determine available resource units (RUs) within a wireless channel that has a punctured frequency range. The WLAN device may allocate a plurality of RUs, from among the available RUs, for to include data for a same station. For example, a physical layer protocol data unit (PPDU) may include more than one RU for a first station. The RUs that are allocated to the first station may exclude the punctured frequency range. In some implementations, the plurality of RUs may be separated by at least the punctured frequency range. A signaling header in the PPDU may indicate which RUs are allocated to the first station. By allocating a plurality of RUs in a PPDU, a WLAN may support per-station puncturing within the PPDU.

Abstract: Embodiments provide a network access method and a device. In accordance with the method, a preamble sequence may be received by a second network device from a terminal device on a time-frequency resource occupied by the preamble sequence. A transmit beam may be determined for sending an access response message to the terminal device. The access response message can be sent to the terminal device using the transmit beam.

Therefore, a rate that the terminal device succeeds in accessing the second access device is improved.
