Abstract: An extremely high-throughput (EHT) station (STA) is configured for transmission of a control response frame for rate selection. In response to a frame carried in an EHT PPDU soliciting a control response frame, the EHT STA may calculate a duration of a non-HT PPDU containing the control response frame sent at a primary rate, The EHT STA may also encode a high-efficient (HE) single-user (SU) PPDU (HE SU PPDU) for transmission to carry the solicited control response frame when a transmit time of the encoded HE SU PPDU is less than the calculated duration of the non-HT PPDU, or encode an EHT PPDU for transmission to carry the solicited control response frame when a transmit time of the encoded EHT PPDU is less than the calculated duration of the non-HT PPDU. A reduction in overhead may be achieved by using an HE SU PPDU or an EHT PPDU instead of a non-HT PPDU to carry a solicited control response frame.

Abstract: A system, method and non-transitory computer readable media for facilitating network connectivity in a split architecture fronthaul network (102) comprising a plurality of cells (118-1 to 118-5, 120-1 to 120-5) and one or more BBU hubs (108A, 108B), each hub comprising at least a BBU (110-N, 112-M). An example cell allocation process (400B, 500A) is configured to assign cells to the hubs sequentially, i.e., a hub must be completely full (e.g., with respect to certain predetermined capacity such as port utilization) before adding cells to any other hubs. Once a hub is full, the allocated cells are further assigned to the individual BBUs of the hub also sequentially (500B). An optimal cell allocation map (418) is thereby obtained, which may be used in (re)configuring the connectivity between the cells (118-1 to 118-5, 120-1 to 120-5) and the hubs/BBUs (110-N, 112-M).

Abstract: A display system for a vehicle includes: an application server including a switched outputter that switches between destinations to one of which the vehicle signal is to be outputted, and outputs the vehicle signal, and image generators that generate an image signal based on the vehicle signal; display clients that display an image based on the image signal; and a signal path determiner that determines a first signal path for transmission of the vehicle signal and the image signal among signal paths connecting the switched outputter, the image generators, and the display clients. When an anomaly occurs in at least one element among the image generators and the display clients, the signal path determiner changes a signal path for transmission of the vehicle signal and the image signal from the first signal path to a second signal path.

Abstract: This disclosure describes techniques for improving convergence of Protocol Independent Multicast assert state information in multicast groups. A method includes forwarding, by a router, a PIM join message originating from a destination host and stores distribution tree information based on the join message. The method further includes participating, by the router, in a Protocol Independent Multicast (“PIM”) assert election among a plurality of routers and storing, by the router, PIM assert state information based on an outcome of the PIM assert election. The method further includes acquiring, by the router, routing information base (“RIB”) convergence. The method further includes triggering by the router, or causing, by the router, another router to trigger, a PIM assert among the plurality of routers. The method further includes re-converging, by the router, with PIM assert states among the plurality of routers and storing, by the router, converged PIM assert state information.

Abstract: Apparatus and methods are provided for efficient bandwidth adaptation for wideband carrier. In one novel aspect, the UE starts a BWP timer upon detecting one or more BWP timer starting triggering events, resets the BWP timer upon detecting BWP resetting triggering events, and switches to the default BWP upon expiration of the BWP timer. The BWP timer starting triggering events comprises decoding a command to switch away from the default BWP, the detection of end of DL data transmission in DRX mode. In another novel aspect, the UE only decodes the DCI indication for active BWP switching in the first three OFDM symbols of a subframe or a slot. In yet another novel aspect, when the SPS is configured for the serving cell for a UE with multiple BWPs, the SPS is configured for all the BWPs accordingly.

Abstract: PDSCH resource allocations can be received. Different PDSCH resource allocations of the PDSCH resource allocations can be associated with different spatial filters for a user equipment. A pre-emption indication that indicates pre-empted resources can be received. A determination can be made as to whether the pre-emption indication is applicable to a first or second PDSCH resource allocation, both the first and the second PDSCH resource allocations, or no PDSCH resource allocation.

The pre-emption indication can be a first pre-emption indication with a first bit-field size and can be indicated in a DCI containing a second pre-emption indication with a second bit-field size different than the first bit-field size.

Abstract: Methods, systems, and apparatuses for discovering dynamic path maximum transmission unit (PMTU) between a sending computing device and a receiving computing device (e.g., a client device and a host device) are described herein. A sending computing device may iteratively transmit bursts of probe packets, each burst being defined by a search range between a maximum packet size and a minimum packet size. The sending computing device may iteratively update the search range based on the previous iteration until the search converges on the PMTU. When the PMTU is discovered, each of the computing devices may update their transport and presentation layer buffers based on the discovered PMTU without any other protocol level disruption. In a multi-path scenario, the computing device may discover PMTU for each of the paths and select a performance optimal path based on the individual PMTUs and other network characteristics such as loss, latency, and throughput.
