Abstract: Embodiments of this application provide a random access method, a communications apparatus, a chip, and a storage medium. A network device sends a first synchronization signal/PBCH block SSB on a first candidate SSB occasion, and/or sends a second SSB on a second candidate SSB occasion, where both the first candidate SSB occasion and the second candidate SSB occasion are associated with a first random access channel time-frequency-code resource.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) is configured such that sounding reference signal (SRS) is switched among a number of antennas on a number of carriers associated with a default data subscription (DDS). The UE is also configured to receive a signal, scheduled using discontinuous reception (DRX), and associated with a non-default data subscription using at least one of the antennas used by the DDS. The UE determines based on carrier characteristics which resource is used to receive the signal during a DRX cycle. In some aspects, the decision is based on avoiding a conflict between the SRS switching and DRX reception. In further aspects, the decision is based on selecting the carrier contributing least to downlink throughput.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a full-duplexing rule that indicates to refrain from using a transmission dropping rule for transmission direction conflicts that occur between uplink and downlink transmissions in a same symbol. The UE may receive a control message scheduling transmission of a message during a symbol, where a transmission direction conflict arises between a first transmission direction of the message and a second transmission direction of the symbol. For example, the UE may identify a transmission direction conflict between an uplink transmission direction of the message and a downlink transmission direction of the symbol. The UE may communicate the message during the symbol based on the full-duplexing rule. The described techniques may enable the UE to attain reduced latency and higher throughput based on reducing a number of transmissions dropped by the UE.

Abstract: A communication method and a communications apparatus are provided. A principle of the method is as follows. Currently, for downlink data transmitted in a semi-persistent scheduling manner, only 1-bit acknowledgment information can be fed back in one time unit. However, as a transmission periodicity P of the downlink data transmitted in the semi-persistent scheduling manner becomes smaller, multi-bit acknowledgment information may need to be fed back in one time unit. In view of this, this application provides a communication method and a communications apparatus to feed back multi-bit acknowledgment information in one time unit. First, multi-bit acknowledgment information to-be-sent in one time unit is determined; then N acknowledgment codebooks are generated, where the N acknowledgment codebooks are used to carry the multi-bit acknowledgment information; and finally, the N acknowledgment codebooks are sent in the time unit.
