摘要： A method of method of dynamic channel switching by a station (STA), including: receiving a resource unit (RU) allocation in an initial frame exchange; determining that the STA cannot operate in its operating BW covering a primary channel based upon the RU allocation; switching to secondary channel(s) per an RU allocated to it to carry out communication by the STA during a transmit opportunity (TXOP); carrying out the communication during the TXOP; and switching back to the primary channel no later than an end of the TXOP if detecting that an AP will not do the initial frame exchange with it in the secondary channel(s) within the TXOP.

摘要： There is provided mechanisms for multiplexed transmission of data packages towards a terminal device. A method is performed by a network node. The method comprises multiplexing, for the terminal device, at least one data package of a first service having a first QoS requirement with at least one of at least two duplicated data packages of a second service having a second QoS requirement, different from the first QoS requirement. The method comprises transmitting the multiplexed data packages towards the terminal device over at least two independent paths. The duplicated data packages are transmitted on mutually different ones of the at least two independent paths.

摘要： The present specification proposes a method of applying a preamble puncturing technique to MU-RTS and CTS frames, and a method including information related to the preamble puncturing technique by the MU-RTS and CTS frames. A station may transmit a first Physical Protocol Data Unit (PPDU) including a MU-RTS trigger frame through a first band, wherein the MU-RTS trigger frame includes preamble puncturing information, wherein the preamble puncturing information indicates a second band to which preamble puncturing is applied to the first PPDU within the first band.

摘要： Wireless communications systems and methods related to downlink (DL) control channel communications are provided. A wireless communication device identifies a search space set including a plurality of PDCCH candidate search spaces for a downlink control channel. The wireless communication device determines that a first resource associated with a first PDCCH candidate search space of the plurality of PDCCH candidate search spaces overlaps with a preconfigured resource. The wireless communication device monitors for a downlink control message over the downlink control channel by excluding monitoring in at least the first PDCCH candidate search space based on the determining.

摘要： A transmitter is provided. The transmitter includes: a Low Density Parity Check (LDPC) encoder configured to encode outer-encoded bits to generate an LDPC codeword including LDPC information bits and parity bits; a puncturer configured to puncture some of the parity bits included in the LDPC codeword; and a mapper configured to map the LDPC codeword except the punctured parity bits to symbols for transmission to a receiver, wherein the puncturer calculates a number of parity bits to be punctured among the parity bits included in the LDPC codeword based on a number of the outer-encoded bits, a number of the LDPC information bits, and a minimum number of parity bits to be punctured among the parity bits included in the LDPC codeword.

摘要： A dynamic channel switch for a transmit opportunity in wireless networks is described. In an example, a second wireless device has a transceiver configured to receive on a primary channel from a first device, a channel switch announcement from the first device. The second wireless device has a controller configured to perform a channel switch to a secondary channel at a beginning of a transmit opportunity (TXOP) for remaining frame exchanges within the TXOP in response to the channel switch announcement.

摘要： The present disclosure relates to transmitting transport blocks in subframes of a predefined length within a wireless communication system. A downlink control information including a resource grant comprising a predetermined modulation and a predetermined transport block size is received (user equipment is the transmitter) or generated (base station is the transmitter). Then transport block including channel coded data to be transmitted in a subframe with the predetermined modulation and the predetermined transport block size is generated. Sensing is performed in the subframes and based thereon, it is determined whether a partial subframe or a complete subframe is available for transmission of the generated transport block. Finally, the transport block is transmitted with a modified modulation different from the predetermined modulation if the partial rather than complete subframe is available. Correspondingly, at the receiver, the grant is received (user equipment is receiver) or generated (base station is the receiver), the size of the subframe in which the reception is expected is determined and then the transport block is received with a modified modulation if only the partial subframe is available.

摘要： Proposed are a method and apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The PPDU includes a control field and a data field. When the broadband is a 320/160+160 MHz band including first to fourth 80 MHz sub-channels, the first 80 MHz sub-channel includes a first 996 RU, the second 80 MHz sub-channel includes a second 996 RU, the third 80 MHz sub-channel includes a third 996 RU, and the fourth 80 MHz sub-channel includes a first 484 RU. The data field is received through a first multiple RU in which the first to third 996 RUs and the first 484 RU are aggregated.
