Abstract: Methods and apparatus for supporting transmission bursts in unlicensed spectrum are described. Different sets of sub-bands within a downlink bandwidth portion of unlicensed spectrum can be, and sometimes are, occupied during different DL transmission bursts depending on channel availability. A user device is configured with channel usage information, e.g. N bitmaps, each bitmap indicating a different control channel resource allocation that may be used for communication with the UE, and/or reference signal information. The UE determines the occupied sub-bands in a DL transmission burst over the bandwidth portion, and determines control channel resource information based on the determined occupied sub-channels. The UE determines CSI-RS measurement locations based on determined sub-band occupancy. In some embodiments, the UE performs in-sync and out-of-sync evaluations based BLER threshold scaling factors, which are based on sub-band occupancy.

Abstract: Methods and apparatus for supporting prioritized transmission opportunity (TXOP) sharing in wireless communications systems, e.g., various 802.11 wireless communications systems, are described. A wireless station may be allocated a transmission opportunity. A shared transmission type of trigger frame is implemented, which allows the wireless station, acting as a host station, to make available transmission resources, which have been acquired by the wireless station, to one or more guest stations. A trigger based (TB) frame, corresponding to the transmitted shared transmission type trigger frame, is used by the host station and one or more guest stations to transmit data to an access point. An access point transmits priority information, e.g., in management frames, to control the use of shared resources in TB frames corresponding to shared transmission type trigger frames.

A novel shared transmission type of trigger frame is implemented, which allows a wireless station, acting as a host station, to make available transmission resources, which have been acquired by the wireless station, to one or more guest stations. A shared transmission type of trigger frame, generated and transmitted by the host station communicates information identifying the attributes of a corresponding trigger based (TB) frame, information identifying resources of the TB frame to be used by the host station and information identifying one or more set of shared resources which may be used by guest station(s). The trigger based (TB) frame, corresponding to the transmitted shared transmission type trigger frame, is used by the host station and one or more guest stations to transmit data to an access point.

Abstract: Apparatus and methods for physical cell identification within one or more wireless networks. In one embodiment, conflicts in PCI values which may exist within two or more mobile networks (e.g., PLMNs) of respective different operators when unlicensed spectrum is utilized (e.g., according to 3GPP 5G NR-U technology) are resolved.

In one variant, the measurement reporting is configured to comply with 5G NR-U required “listen-before-talk” or LBT protocols; i.e., to measure parameters consistent with the LBT protocols to detect any such PCI-based conflicts.

Abstract: Radio Link Control ACK/NACK is conditionally suppressed. A first wireless communications device including a radio transmitter identifies a first packet flow for which end to end packet retransmission is supported. The first wireless communications device identifies a Packet Data Convergence Protocol (PDCP) packet corresponding to Radio Link Control Acknowledged Mode (RLC AM), said identified packet being included in the identified first packet flow. The first wireless communications device generates an Acknowledged Mode Protocol Data Unit (AM PDU) including a No RLC ACK Required (NRAR) indicator set to indicate RLC ACK is not required, and the radio transmitter in the first wireless communications device transmits the AM PDU, e.g., an AMD PDU, to a second wireless communications device. The second wireless communications device receives the transmitted AM PDU, recovers the NRAR indicator value, and based on the communicated value of the NRAR indicator, determines to suppress RLC ACK/NACK.
