摘要： A system and a method are disclosed for determining, by a targeted receiving User Equipment (UE), that a corresponding transmitting UE has a future reserved resource block. The receiving UE may perform a Listen Before Talk (LBT) sensing to identify a time period when an unlicensed channel is unoccupied and can be used by the corresponding transmitting UE for the future reserved sidelink transmission. The receiving UE may transmit a reservation signal for the unlicensed channel to the corresponding transmitting UE, during at least a portion of the time period when the unlicensed channel is unoccupied. Further, the receiving UE may, switch, to a receiving mode prior to or at a reserved slot boundary of the future reserved resource block.

摘要： A system and method for managing a Discovery Burst Transmission Window in a wireless communication system. In some embodiments, the method includes: receiving, by a User Equipment (UE), a first Signal Synchronization Block (SSB); decoding a first Physical Broadcast Channel (PBCH) from the first SSB; determining, from a Master Information Block (MIB) of the first PBCH, a first beam value; determining, from the first PBCH, a first candidate Synchronization Signal/Physical Broadcast Channel (SS/PBCH) block index; and calculating a first SS/PBCH block index as A mod Q, wherein A is the first candidate SS/PBCH block index and Q is the first beam value.

摘要： A system and method for channel access mode selection. In some embodiments, the method includes receiving, by a user equipment (UE), an interference measurement configuration from a network; performing, by the UE, a first interference measurement according to the interference measurement configuration; and implementing a first channel access mode. The implementing of the first channel access mode may include (i) identifying, by the UE, the first channel access mode based on the first interference measurement; or (ii) reporting, by the UE, a result of the first interference measurement, in order for the first channel access mode based on the first interference measurement to be identified.

摘要： A method for random access in a communication network may include detecting a first candidate beam at a UE, detecting a second candidate beam at the UE, transmitting, from the UE, one or more first messages of a random access procedure, and indicating, by the one or more first messages, the first candidate beam and the second candidate beam. Another method for random access in a communication network may include detecting a first candidate beam at a UE, detecting a second candidate beam at the UE, receiving, at the UE, traffic information for the first candidate beam and the second candidate beam, selecting the first candidate beam based on the traffic information, and transmitting, based on the selecting, a first message of a random access procedure using the first candidate beam. The traffic information comprises load information.

摘要： A system and a method are disclosed for beam refinement to enable inactive mode transmission in frequency range 2 for 3GPP RedCap devices. A RedCap device receives system information in a SIB1 from a wireless network in which the SIB1 includes information relating to an indication of resources used to transmit a SIB-x. The device receives the SIB-x, which includes an indication of at least one resource, at least one configuration for a Downlink-Reference Signal (DL-RS) transmission, and information relating to a measurement report relating to the beam-refinement measurement that is to be performed by a device. The device receives the DL-RS transmission from the wireless communication network, performs the beam-refinement measurement, and sends a measurement report to the wireless network. Subsequent to sending the measurement report, the device sends an enhanced transmission to the wireless network based on the measurement report.

摘要： A system and a method are disclosed for processing, by a user equipment (UE), a first automatic gain control (AGC) symbol at a first slot of a wireless transmission; receiving, by the UE, an indication of a number of AGC symbols for processing in the wireless transmission; and determining, by the UE and based on the indication received, whether to process at least a second AGC symbol of the wireless transmission. The indication may include information that at least the second AGC symbol exists in a subsequent slot of the wireless transmission and the UE may further processing, based on the determination and indication, at least a second AGC symbol. The UE may further send, to a separate transmitting (Tx) UE, a request to send the wireless transmission comprising multiple AGC symbols, wherein the indication is based on the request sent to the Tx UE.

摘要： A user equipment (UE) apparatus for wireless communication with a base station is provided. The UE includes a transceiver and a processor. The processor is configured to transmit, to the base station, via the transceiver, at least one uplink (UL) data packet in a radio resource control (RRC) inactive state, and in response to a UL transmission failure, fall back to a random access channel (RACH) transmission mode, and receive, from the base station, via the transceiver, a message indicating the UE to change from the RACH transmission mode to a configured grant-based transmission mode.
