  • Publication number: 20240188121
    Abstract: A configuration for transmission control for multi-relay based communication. The apparatus determines a priority of data transmission at each relay of a plurality of relays between the base station and at least one UE. The apparatus transmits a PDSCH comprising control information for the at least one UE and a priority indication instructing each relay of the plurality of relays which data is contained in the PDSCH. The PDSCH may include an indication indicating whether data corresponding to the at least one UE is contained in the PDSCH. The PDSCH may include a field that identifies data and a corresponding UE of the at least one UE that is contained in the PDSCH. The apparatus may transmit, to each relay of the plurality of relays, the priority of data transmission, wherein the priority of data transmission includes a priority for uplink and downlink transmissions.

  • Publication number: 20240147460
    Abstract: A configuration for resource allocation for PDCCH with multi-relay based communication. The apparatus determines a transmission time of a signal comprising a sequence of a plurality of PDCCHs to a target node. At least one relay is between the base station and the target node. The apparatus transmits, to each of the at least one relay, a relay configuration comprising scheduling information for each of the at least one relay to relay the signal. The scheduling information is based on a determination of the transmission time of the signal to the target node.

  • Patent number: 11956079
    Abstract: Aspects of the disclosure relate to rate-matching a stream of bits encoded using polar codes. An exemplary method generally includes determining a mother code size (N) for transmitting an encoded stream of bits based, at least in part, on a minimum supported code rate for transmitting the encoded stream of bits (Rmin), a control information size of the encoded stream of bits (K), a number of coded bits for transmission (E), and a maximum mother code size (Nmax), encoding a stream of bits using a polar code of size (N, K) and storing the encoded stream of bits in a circular buffer, and performing rate-matching on the stored encoded stream of bits based, at least in part, on a comparison among the mother code size (N), the control information size of the encoded stream of bits (K), and the number of coded bits for transmission (E).

  • Publication number: 20240107579
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate with multiple transmit receive points (TRPs) in a frame based equipment mode. A wireless node (e.g., the UE and/or one or more of the multiple TRPs) may determine, among the UE and the multiple TRPs, an initiating node that acquired a current channel occupancy time. The wireless node may determine a transmission pattern that includes one or more idle periods based at least in part on a fixed frame period structure associated with the initiating node that acquired the current channel occupancy time. The wireless node may refrain from transmitting during the one or more idle periods, wherein the one or more idle periods include at least an idle period associated with the wireless node. Numerous other aspects are described.

  • Publication number: 20230159694
    Abstract: The present disclosure discloses a waterborne epoxy resin for an anti-corrosion coating, and a preparation method and use thereof. In the preparation method, a strongly-hydrophilic polyethylene glycol (PEG) branch is introduced into a molecular chain of epoxy resin to realize the self-emulsification function of epoxy resin. Moreover, due to the short molecular chain, a solid content can reach up to 66.7% under the action of PEG. In addition, the waterborne emulsion can be prepared without adding any additional alcohol-soluble solvents and other high-boiling-point organic solvents, and a production process and a product use process both are very environmentally friendly. The waterborne epoxy resin can be mixed with a waterborne ammonia curing agent to form a film for corrosion protection.
