  • Publication number: 20210289448
    Abstract: Methods and apparatuses are described herein for adapting clear channel assessment (CCA) thresholds with or without Transmit Power Control (TPC) are disclosed. An IEEE 802.11 station (STA) may dynamically calculate a STA specific transmit power control (TPC) value and a STA specific clear channel assessment (CCA) value based on a target TPC parameter and a target CCA parameter. The target TPC parameter and the target CCA parameter may be received from an IEEE 802.11 cluster head configured to control TPC and CCA for a plurality of STAs associated with the BSS. The target TPC parameter and the target CCA parameter also may be related. The STA may then determine whether a carrier sense multiple access (CSMA) wireless medium of a wireless local area network (WLAN) basic service set (BSS) is occupied or idle based on the STA specific CCA value.

  • Patent number: 11121815
    Abstract: Systems, methods and instrumentalities are disclosed for decoding data. For example, it may be determined, in a current slot, whether data received in a previous slot is decoded successfully. The data received in the previous slot may be included in a Physical Downlink Shared Channel (PDSCH). If the data received in the previous slot is not decoded successfully, preemptive multiplexing information may be detected in a first search space. The data received in the previous slot may be decoded, for example, using detected preemptive multiplexing information. The preemptive multiplexing information may be of a current slot. The preemptive multiplexing information may be comprised in a first DCI. A second search space of the current slot may be searched. For example, the second search space may be searched for a second DCI. The first DCI and the second DCI may be different.

  • Publication number: 20210243628
    Abstract: Device, systems, and/or techniques for using sub-channel signaling information between an access point and a first station are disclosed. An uplink trigger sent from the access point to the first station may be received. A map may be transmitted from the first station indicating at least one sub-channel that is available for spatial sharing by a second station. The first station may receive an acknowledgement from the access point that data was transmitted from the second station on the at least one sub-channel and/or received by the at least one access point. An OFDMA transmission having a sub-channel/sub-band available for transmitting data may be determined. An energy in the sub-channel/sub-band may be measured and/or compared to a dynamic and/or static threshold. Whether a sub-channel/sub-band is free or busy may be determined for example based on if the measured energy is, or is not, greater than the threshold.

  • Patent number: 11026187
    Abstract: Methods and apparatuses are described herein for determining a transmit power based on clear channel assessment (CCA) thresholds. A station (STA) associated with a first Basic Service Set (BSS) may receive, from an access point (AP) associated with the first BSS, a clear channel assessment (CCA) value for a group of STAs associated with a second BSS. The CCA value may indicate a minimum CCA threshold for a packet received from the second BSS. The STA may then determine, based on the CCA value, a STA specific CCA parameter and a target CCA parameter. The target CCA parameter may be greater than or equal to the STA specific CCA parameter. Based on the STA specific CCA parameter and the target CCA parameter, the STA may determine a target transmit power control (TPC) parameter of the STA, wherein the sum of target TPC parameter and target CCA parameter is constant.

  • Publication number: 20210152233
    Abstract: A WTRU may include a memory and a processor. The processor may be configured to receive beam grouping information from a gNB or transmission and reception point (TRP). The beam grouping information may indicate a group of beams that the WTRU may report using group-based reporting. The group-based reporting may be a reduced level of reporting compared to a beam-based reporting. The group-based report may include measurement information for a representative beam. The representative beam may be one of the beams in the group or represents an average of the beams in the group. Alternatively, the representative beam may be a beam that has a maximum measurement value compared to other beams in the group. The group-based report may include a reference signal received power (RSRP) for the representative beam and a differential RSRP for each additional beamin the beam group.

  • Publication number: 20210029658
    Abstract: Methods, systems, and devices for addressing timing advance (TA) in non-terrestrial network communication is disclosed herein. A wireless transmit and receive unit (WTRU) may receive system information from a base station attached to an airborne or spaceborne vehicle that indicates a physical random access channel (PRACH) resource. The WTRU may determine a timing offset based on a plurality of information, such as the location information and the system information. The WTRU may transmit a preamble using the timing offset via the PRACH resource. The base station may receive the preamble and send a random access response (RAR) that includes, for example, a TA command. The WTRU may receive the RAR including the TA command and combine the timing offset with the TA command to determine an actual TA, after which the WTRU may use the actual TA for uplink transmissions.
