摘要： Disclosed is a wireless communication terminal to communicate wirelessly. The wireless communication terminal includes: a first wireless transceiver configured to transmit and receive signals modulated by a first modulation method; a second wireless receiver configured to receive a signal modulated by a second modulation method different from the first modulation method; and a processor. The processor is configured to sequentially receive a plurality of fields of a wake-up radio (WUR) frame included in a WUR physical layer processing data unit (PPDU) transmitted by the second modulation method, and when a predetermined condition for the plurality of fields is satisfied, stop receiving the WUR frame without determining whether values of the plurality of fields are valid.

摘要： A wireless device may communicate with multiple base stations via multiple cells. The wireless device may indicate to at least one of the base stations a failure of a listen-before-talk (LBT) procedure. A base station may reconfigure another base station based on the failure of the LBT procedure.

摘要： The present specification proposes a new procedure of signal transmission or reception between STAs in a case of sensing measurement initiated by an STA rather than an AP. According to an embodiment of the present specification, proposed is a sensing measurement procedure performed by an AP in response to transmission of a sensing initiation frame to the AP by an STA rather than the AP. According to another embodiment of the present specification, according to an embodiment of the present specification, proposed is a procedure in which an STA rather than an AP transmits a sensing initiation frame to the AP, and then the AP requests respondent STAs to transmit NDP frames. According to yet another embodiment of the present specification, proposed is a method for configuring a frame transmitted or received in the above procedures.

摘要： Fallback procedures for user equipments (UEs) are described that provide efficient fallback to a four-step random access procedure from a two-step random access procedure. For example, after transmitting a first message of a two-step random access procedure, a UE may start a fallback timer or counter and monitor for a second message of the two-step random access procedure for the duration of the fallback timer or counter. At the expiration of the fallback timer or counter, the UE may fall back to a four-step random access procedure. In some cases, the UE may transmit multiple repetitions of the first message and monitor for responses after transmitting the repetitions or after each repetition. Additionally, or alternatively, the base station may transmit an explicit signal to the UE that may signal to the UE to perform a fallback procedure at a beginning or middle of a random access procedure.

摘要： A method of wireless communication includes determining, by a communication device, a value of a counter associated with a listen-before-talk (LBT) operation. The method further includes, after determining the value of the counter and during a first portion of a deferral interval associated with the LBT operation, performing a first measurement of a particular duration to determine a first energy value. The method further includes, during a second portion of the deferral interval subsequent to the first portion, performing a second measurement of the particular duration to determine a second energy value. The method also includes determining whether to initiate a contention interval associated with the LBT operation based on the first energy value and further based on the second energy value.

摘要： This document describes techniques and apparatuses for joint-transmission over an unlicensed frequency band using a user equipment (UE)-coordination set. In aspects, a first UE in a UE-coordination set acts as a coordinating UE. The coordinating UE receives, using a local wireless network connection, uplink data from a second UE in the UE-coordination set. The coordinating UE distributes, using the local wireless network connection, the uplink data to at least a third UE in the UE-coordination set. The coordinating UE receives, from at least one UE in the UE-coordination set, respective results of a clear channel assessment of the unlicensed frequency band. The coordinating UE determines a specified time to begin joint-transmission of the uplink data based on the results and coordinates the joint-transmission by directing the at least one UE to initiate the joint-transmission of the uplink data based on the specified time.

摘要： Proposed are a method and an apparatus for receiving a PPDU over a broadband in a wireless LAN system. Specifically, a receiving STA receives the PPDU from a transmitting STA through a broadband. The receiving STA decodes the PPDU. The broadband is a 320 MHz band or a 160+160 MHz band. The PPDU includes first and second SIG fields. The first SIG field includes information on a broadband bandwidth. The information on the broadband bandwidth consists of 3 bits or 4 bits.
