    Abstract: Systems and methods are provided for transmitting and receiving pre-emption indications. The pre-emption indication is transmitted every K symbols or slots, on a group-common physical downlink control channel. The pre-emption indication is in respect of a group of K symbols or slots preceding a symbol or slot containing the group-common pre-emption indication. The group-common pre-emption indication indicates, for the group of K symbols or slots, which resources are pre-empted. The base station schedules resources for first downlink traffic, and transmits the scheduled first downlink traffic subject to pre-emption, and transmits second downlink traffic by pre-empting resources for the first downlink traffic. On the UE side, the UE receives the pre-emption indication. The UE receives its scheduled traffic taking into account the pre-emption indication.

    Abstract: The method includes generating, by an access point (AP), signaling that includes an AP identifier (ID) field, a bandwidth (BW) field, a guard interval (GI) field, a cyclic redundancy check (CRC) field, and a tail field, the AP ID field is used to indicate an ID of the AP, the BW field is used to indicate bandwidth required for data transmission subsequent to the signaling, the GI is used to indicate a length of a cyclic prefix (CP) required for data transmission subsequent to the signaling, the CRC field is used to guard a field before the CRC field in the signaling, and the Tail field is used to empty an encoder and a decoder, where the CRC field and the Tail field are the last two fields of the signaling. The method also includes sending, by the AP, the signaling.

    Abstract: Methods and systems for access to unlicensed spectrum are described. Each of one or more transmit points (TPs), transmit over an unlicensed spectrum a downlink transmission starting at a downlink transmission starting time after a successful clear channel assessment (CCA) process of each of the one or more TPs. For each of the one or more TPs, the successful CCA process has a CCA process starting time enabling the successful CCA process to be completed at the downlink transmission starting time. The one or more TPs may be licensed assisted access (LAA) TPs, and the starting time corresponds to a starting time of a licensed spectrum subframe.

    Abstract: A resource indication method in a wireless local area network is provided, where the method includes generating, by an access point, a data frame that includes a preamble, where the preamble includes a signaling indication part B (SIG-B), the SIG-B includes a common part and a user part following the common part. The common part is used to indicate a quantity of scheduled stations, identification information of the scheduled station, and a location of communication resource information of the scheduled station in the user part, the user part is used to indicate the communication resource information of the scheduled station, and the communication resource information includes resource indication information, MCS information of a data part, spatial flow quantity information, or power control information; and sending the data frame.

    Abstract: Embodiments of the present invention provide a method and an apparatus for setting up an interface between access points, where a first AP receives measurement information reported by at least one station associated with the first AP, to learn an AP identifier of a second AP having a capability of supporting an AP2AP interface, determines an AP identifier of a candidate AP according to interface information in the measurement information, and sends, to the candidate AP by using an AC, a first request message requesting an IP address used for setting up a communications interface between APs, the candidate AP sends, by using the AC, a response message to the first AP according to the first request message, and the first AP determines, according to the response message, whether to set up an AP2AP communications interface with the candidate AP that sends the response message.

    Abstract: A method for dynamically dividing or consolidating sub-bands in-between Clear Channel Assessment (CCA) status measurements upon detection of a CCA bandwidth adjustment condition is provided. The method includes determining at least a single CCA status for at least a single sub-band during a first period, and detecting a CCA bandwidth adjustment condition for dividing the single sub-band into two or more separate sub-bands, where a combination of the two or more separate sub-bands occupies the same frequency band as the single sub-band. The method also includes determining a separate CCA status for each of the two or more separate sub-bands during a second period. An apparatus for performing this method is also provided.
