METHOD AND DEVICE IN NODES USED FOR WIRELESS COMMUNICATION
Method and device in nodes used for wireless communication. A first node receives a first signaling, receives a second signaling, and transmits a first signal in a first radio resource block. The first signal comprises a second sub-signal; a value of a first field in the first signaling is used to indicate a first offset from a first offset set, a value of a first field in the second signaling is used to indicate a second offset from a second offset set, only the second offset is used to determine a number of Resource Element(s) (RE(s)) occupied by the second sub-signal in the first radio resource block; the first signaling is used to determine a first priority, the second signaling is used to determine a second priority, a signaling format of the first signaling is used to determine that the first offset set is related to the first priority.

The MCS is an MCS used for each of the plurality of channel sets, or an MCS used for each of the plurality of resource units.
Channel width, spatial streams, and short packet signaling
Methods, apparatuses, and computer readable media include an apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a legacy preamble of a physical layer (PHY) protocol data unit (PPDU), determine whether the legacy preamble comprises an indication that the PPDU is an extremely-high throughput (EHT) PPDU, and in response to the determination indicating the PPDU is the EHT PPDU, decode the EHT PPDU. Some embodiments determine a spatial stream resource allocation based on a row of a spatial configuration table, a row of a frequency resource unit table, a number of stations, and location of the station relative to the number of stations in user fields of an EHT-signal (SIG) field. To accommodate 16 spatial streams, some embodiments extend the length of the packet extension field, extend signaling of a number of spatial streams, and/or extend a number of EHT-SIG symbols.
Resource allocation and segmentation in wireless systems
Methods, systems, and devices for wireless communications are described that may enable a user equipment (UE) to transmit sidelink data within an interference avoidance resource scheduling scheme. For example, a UE may determine to segment a data packet for transmission in a vehicle-to-everything (V2x) system (e.g., to ensure that each segment fits within one transmission time interval (TTI)). In some cases, a UE may identify a data packet for transmission, may determine that the size of the data packet exceeds a threshold size, may segment the data packet to ensure each segment fits within one TTI, and may transmit the data packet segments (e.g., to additional UEs), where said transmissions may be discontinuous. In some examples, a UE may determine to segment the data packet and then encode the data packet. Additionally or alternatively, the UE may determine to encode the data packet and then segment the data packet.
Method for error handling of an interconnection protocol, controller, and storage device
A method for error handling of an interconnection protocol, a controller and a storage device are provided. The method for error handling of an interconnection protocol is for use in a first device that is linkable to a second device according to the interconnection protocol, the method comprising: during or after a power mode change of a link between the first device and the second device: a) triggering, by the first device, a first line reset signal to the second device; b) performing, by the first device, suppression of detected rate overlap errors; and c) stopping the suppression of detected rate overlap errors after the first device receives a second line reset signal from the second device.
Vector signaling code with improved noise margin
Methods are described allowing a vector signaling code to encode multi-level data without the significant alphabet size increase known to cause symbol dynamic range compression and thus increased noise susceptibility. By intentionally restricting the number of codewords used, good pin efficiency may be maintained along with improved system signal-to-noise ratio.
Messaging via low energy wireless transmissions
A protocol layer on top of the Bluetooth low energy (BLE) system of paired devices to provide transmission that allows arbitrary sizes of data to be sent. To guarantee transmissions, the transmissions may be validated and, if required, resent to replace data that was lost or corrupted. The protocol layer also supports Remote Procedure Calls to allow functions on either of two connected devices to be executed on one device on behalf of the other. A further protocol layer also allows high priority, short messages to temporarily interrupt the transmission of low priority, long messages.
Multi-stride packet payload mapping for robust transmission of data
Systems and methods for packet payload mapping for robust transmission of data are described. For example, methods may include receiving, using a network interface, packets that each respectively include a primary frame and one or more preceding frames from the sequence of frames of data that are separated from the primary frame in the sequence of frames by a respective multiple of a stride parameter; storing the frames of the packets in a buffer with entries that each hold the primary frame and the one or more preceding frames of a packet; reading a first frame from the buffer as the primary frame from one of the entries; determining that a packet with a primary frame that is a next frame in the sequence has been lost; and, responsive to the determination, reading the next frame from the buffer as a preceding frame from one of the entries.
