Abstract: According to one configuration, a wireless network includes first wireless stations and second wireless stations. The first wireless stations and second wireless stations support different wireless communication protocols and compete to use a wireless channel. Via monitoring of a control channel generated by a management resource associated with at least the first wireless stations, a given wireless station of the second wireless stations determines availability (unused time slots, frames, etc.) of the wireless channel via monitoring of the wireless channel itself and/or a control channel. In the latter instance, the control channel indicates scheduled usage of the shared wireless channel by at least the first wireless stations. In accordance with the scheduled usage as indicated by the control channel, the given wireless station transmits over the wireless channel during free slots, times, gaps, etc., to communicate with a remote wireless station of the second wireless stations.

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: A first communications device including a transmitter identifies a packet flow for which end to end packet retransmission is supported. The first wireless communications device transmits an explicit indication in a downlink message to a second wireless communications device, to skip Hybrid Automatic Repeat Request (HARQ) feedback for data, corresponding to the first packet flow, said data being directed to the second wireless communications device. In some embodiments, said explicit indication to skip Hybrid Automatic Repeat Request (HARQ) feedback for data is a predetermined value in a predetermined field of a downlink control information (DCI) scheduling message. In some embodiments, the predetermined field is a PDSCH-to-HARQ feedback timing indicator field. HARQ suppression is applied for the first packet flow at a radio link layer and/or MAC layer, e.g., by the second communications device in response to the predetermined value indicating HARQ suppression being recovered from the predetermined field.

Abstract: A network control device, e.g., a gNB, receives a message from a communications device, e.g. a UE, indicating that the communications device is experiencing an in-device coexistence (IDC) problem, e.g. in the 52.6 GHz-71 GHz frequency range with respect to NR-U and WiGig. The message is one of: i) an IDC assistance message indicating that the victim system is Wi-Gig or ii) an antenna panel switch message requesting that the network control device instruct the communications device to change the antenna panel that it uses for uplink NR signaling. The network control device generates and sends a response message to the communications device including: a selected new frequency to be used by the communications device for uplink NR signaling or a selected different antenna panel to be used by the communications device for uplink NR signaling. The communications device implements the change reducing or avoiding the IDC problem.

Abstract: A wireless station is allocated use of a time slot in a given direction, uplink or downlink, on a given channel. The wireless station monitors for presence of wireless energy during a portion of the time slot. Based on a detected level of the wireless energy in the time slot, the wireless station controls transmission of wireless communications in a direction opposite to the configured direction in a remaining part of the time slot.

Abstract: Methods and apparatus for managing system information message transmission in a distribution network (e.g., a wireless network such as one compliant with 3GPP 5G NR-U). In one embodiment, transmission of multiple SI (System Information) messages with overlapping SI-windows is enabled but with no soft-combining support. In another embodiment, transmission of multiple SI-messages with overlapping SI-windows is enabled with soft-combining support. In yet another embodiment, aperiodic OSI transmission is enabled. Moreover, the present disclosure provides mechanisms for notifying UE of an SI change.

Abstract: Methods and apparatus for supporting wireless medium sharing in wireless communications systems, e.g., various 802.11 wireless communications systems, are described. 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 improving coverage and/or power-saving in a wireless network. In one embodiment, the apparatus and methods provide mechanisms for wireless user device (such as e.g., a 3GPP-compliant UE) to utilize downlink transmissions related to a first access technology (e.g., LTE) to enhance the detection and reception of downlink transmissions from a second access technology (e.g., 5G NR). In one variant, transmissions relating both access technologies are multiplexed on a shared frequency channel; a UE trying to detect 5G NR transmissions from a gNB leverages the easier detection of certain LTE signals such as PSS to enhance detection of the 5G NR signals. Moreover, the location of the LTE PSS (or SSS) can be used to indirectly assist a UE with detection of the NR SSB, such as via reduction of the number of noise-only samples passed to the NR PSS/SSS autocorrelation detector.

Abstract: A user equipment (UE) receives time division duplexing (TDD) configuration information from a master node (MN), with which the UE is communicating using a first band of unlicensed spectrum and receives TDD configuration information from a secondary node (SN), which is being added to support communications with the UE using a second band of unlicensed spectrum. The UE compares the two TDD structures, identifying DL and UL slots in SN TDD structure which correspond to DL and UL time intervals in the MN TDD structure, designating at least some of those SN slots as preferred DL slots and preferred UL slots. The UE communicates information indicating its preferred DL slots and preferred UL slots in an assistance message to the SN. The SN using UE slot preference information, selects DL and UL slots to be used for UE communications and implements a TDD structure, which avoids an IDC problem.
