Wireless communication system, mobile station, base station, and wireless communication method
A mobile station including: a communication unit that includes a first logical processing subject and a second logical processing subject that operates in association with the first logical processing subject and performs multiple communications with a first wireless communication apparatus and a second wireless communication apparatus; an accumulation unit that accumulates data received from the second wireless communication apparatus; and a notifying unit that notifies the first wireless communication apparatus of data receiving status in the accumulation unit.
CONFIGURING BEAM MANAGEMENT BASED ON SKIPPED TRANSMISSIONS OF SIGNALS ASSOCIATED WITH BEAM MANAGEMENT
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication regarding one or more signals associated with beam management, the indication indicating one or more future time periods for which the UE may not receive one or more transmissions of the one or more signals. The UE may configure a beam management configuration of the UE based at least in part on the indication. Numerous other aspects are described.
Vehicle-to-vehicle communication system, roadside communication apparatus, in-vehicle communication apparatus, and vehicle-to-vehicle communication method
A vehicle-vehicle communication system performs wireless communication between multiple vehicles each having an in-vehicle communication apparatus that transmits and receives information using a wireless signal. The vehicle-vehicle communication system includes a roadside communication apparatus including a roadside reception unit receiving information transmitted by the in-vehicle communication apparatus using a wireless signal and a roadside transmission unit transmitting the information received by the roadside reception unit using a wireless signal, and relays communication between multiple vehicles. The in-vehicle communication apparatus includes a vehicle-side reception unit that receives information wirelessly transmitted by an in-vehicle communication apparatus mounted in another vehicle and information wirelessly transmitted by a roadside communication apparatus; a determination unit determines whether or not the information received by the vehicle-side reception unit is needed; and an information processing unit performs information processing based on information determined by the determination unit as being needed.

Techniques for switching to fallback beam
Methods, systems, and devices for wireless communications are described. Wireless devices may communicate over a primary and fallback beam. To support communications over a primary and fallback beam, a preconfiguration procedure may be performed to communicate to a transmitting and receiving device the identity of the primary and fallback beam. A central scheduling node may assist in identifying the primary and fallback beam for the transmitting and receiving device. During communications, the transmitting and receiving device may switch to the fallback beam when an initial communication fails and may perform a retransmission that includes data from the initial communication over the fallback beam.
Triggering distributed MIMO communication in a wireless node cluster
Various aspects of the disclosure relate to distributed multiple-input multiple-output (MIMO) communication such as coordinated beamforming or Joint MIMO. In some aspects, distributed MIMO is used to support communication in a cluster of wireless nodes (e.g., access points). A distributed MIMO scheduling scheme as taught herein is used to schedule the wireless nodes (e.g., access points and/or stations) operating within the cluster. For example, selected stations may be triggered to communicate with respective access points.

Carrier interferometry transmitter
A transmitter in a wireless communication network comprises a Carrier Interferometry (CI) coder and a multicarrier modulator communicatively coupled to the CI coder. The CI coder encodes a plurality of data symbols with a plurality of CI codes to produce a plurality of CI symbol values, wherein each of the plurality of CI symbol values equals a sum of information-modulated CI code chips. Each information-modulated CI code chip equals a CI code chip multiplied by one of the plurality of data symbols. The modulator modulates each CI symbol value onto a different subcarrier frequency to produce a multicarrier signal.

UPLINK MULTI-USER EQUIPMENT (UE) COOPERATIVE TRANSMISSION
The present disclosure relates to uplink cooperative multi-User Equipment (UE) cooperative transmission such as Multiple-Input Multiple-Output (MIMO) transmission. Source data of a source UE that is to be transmitted via uplink cooperative transmission by multiple UEs, is transmitted to at least one cooperative UE over an SL. The source data is associated with an identifier for identifying the UE to the network equipment as a source of the source data. The multiple UEs transmit the source data and the identifier in an uplink direction to the network equipment. The network equipment receives the source data from the multiple UEs in a cooperative transmission such as cooperative MIMO transmission, and obtains the identifier for identifying the source UE as the source of the source data.
