  • Publication number: 20200067680
    Abstract: A wireless transmit receive unit (WTRU) may be configured to transmit uplink control information such as Hybrid Automatic Retransmission Request (HARQ) Acknowledgement or Negative Acknowledgement (ACK/NACK) using a sequence. The HARQ ACK/NACK may comprise one bit or two bits of information, and the WTRU may use a cyclic shift of the sequence to transmit the HARQ ACK/NACK. The WTRU may use different cyclic shifts of the sequence to transmit different HARQ ACK/NACK values and the cyclic shifts may be separated from each other in a manner to facilitate the transmissions. The WTRU may be further configured to receive, from a physical downlink control channel (PDCCH), an indication of a resource block for transmitting the HARQ ACK/NACK.

  • Publication number: 20200067577
    Abstract: Methods and apparatus are described herein for dynamic allocation of multiple channels and data streams for multi-channel transmission and multiple-input and multiple-output (MIMO). For example, a station (STA) may receive an enhanced poll (EPoll) frame that includes a time offset, a channel offset and antenna/sector settings from an access point (AP). The STA may transmit, based on the received EPoll frame, an enhanced service period request (ESPR) frame that includes a MIMO control field and a multi-channel control field. The MIMO control field may indicate whether the STA supports MIMO transmission. The multi-channel control field may indicate whether the STA supports multi-channel transmission. Upon transmitting the ESPR frame, the STA may receive an enhanced grant frame from the AP. The enhanced grant frame may include an antenna configuration and a multi-channel allocation to enable the STA to perform the MIMO transmission and the multi-channel transmission.

  • Publication number: 20200059950
    Abstract: Systems, methods, and/or instrumentalities are disclosed for dynamic allocation (e.g. of communication channel time with an access point (AP)) to a plurality of wireless transmit/receive units (STA(s)/WTRUs) in dense mmWave networks. Dynamic allocation may be implemented in multiple (e.g. four) sub-phases, (e.g. a polling period sub-phase with polls, a polling period sub-phase with service period requests (SPRs), a grant sub-phase and/or a data transfer sub-phase). Multi-dimensional dynamic allocation may address multiple STAs simultaneously (e.g. using one or more different dimensions such as space, frequency, and/or code). Directional channel access may provide a contention-based uplink in which STAs compete (e.g. during an uplink request period) to send data requests. Efficient dynamic allocation may optimize signaling and/or operation in sub-phases (e.g. using grouped polling, grouped SPR and/or grouped grant frames).

  • Publication number: 20200059290
    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 beam in the beam group.

  • Publication number: 20200059342
    Abstract: A wireless transmit/receive unit (WTRU) may be configured to perform wake up radio (WUR) for one or more WUR receivers. For example, the WTRU may transmit a common preamble to a first WUR receiver using a first frequency range. The WTRU may transmit a first WUR packet to the WUR receiver, after the common preamble. The WTRU may transmit the common preamble to a second WUR receiver using a second frequency range. The WTRU may transmit a second WUR packet after the common preamble, The bandwidth associated with the second WUR packet and the bandwidth associated with the first WUR packet may be smaller than the bandwidth associated with the common preamble, which may avoid interference from other transmitters {e.g., 802.11 transmitters, 802.11 stations, and 802.11 radios). The bandwidth associated with the first WUR packet and the bandwidth associated with the second WUR packet may not be coextensive with one another.

  • Publication number: 20200052864
    Abstract: Interference for reference symbols in URLLC/eMBB multiplexing may be reduced. URLLC and/or eMBB reference signal (RS) interference may be reduced regardless whether the URLLC and eMBB reference signals and data are multiplexed and superimposed using the same numerology or different numerologies and/or regardless whether the URLLC and eMBB reference signals may be aligned or misaligned (e.g., may or may not use a common resource). An URLLC transmission may preempt an eMBB transmission. For the URLLC and eMBB transmissions using a same numerology, a RS reuse indication may be used. The RS reuse indication may indicate whether a RS in the preempted portion of the eMBB transmission may be reused. A channel estimation function set may be estimated, and channel estimation may be performed using the determined channel estimation function set. The eMBB transmission and the URLLC transmission may be decoded based on the performed channel estimation.

  • Publication number: 20200021419
    Abstract: A wireless transmit/receive unit (WTRU) may receive a PDCCH transmission comprising a CCE that is mapped to one or more REGs based on a CCE-to-REG mapping. The WTRU may receive the CCE-to-REG mapping that indicates a REG bundle corresponding to the CCE and use the CCE-to-REG mapping to identify the REGs for the SWTRU. Depending on whether the CCE-to-REG mapping is interleaving or noninterleaving, the CCE-to-REG mapping may be based on different parameters. If the CCE-to-REG mapping is interleaving, the CCE-to-REG mapping may be based on an index associated with the CCE and a number of REGs in the REG bundle. If the CCE-to-REG mapping is noninterleaving, the CCE-to-REG mapping may be based on the index of the CCE.

  • Patent number: 10511991
    Abstract: Systems and methods are provided for adapting communication parameters to a variety of link conditions, traffic types and priorities. For example, WiFi transmission parameters (e.g. retry limit, AIFS, CW size, MCS order and/or CCA threshold) may be adapted to channel congestion levels, channel errors and/or traffic priority levels. Parameter adaptation may be coordinated across layers (e.g. between MAC and PHY layer parameters). Congestion levels may be detected, for example, using a smoothed queue size and/or channel busy time. Traffic may be transmitted using adapted parameters, such as reduced retry limits for a high congestion level and increased retry limits for priority traffic in response to channel error. Feedback may support parameter adaptation. For example, feedback may be provided by a receiver and/or within a sender, such as a sender MAC and/or PHY layer or a parameter adapter providing feedback (e.g. spoofed NACK packet) to a sender application, transport and/or network layer.
