Abstract: According to one configuration, a system includes a mobile communication device. The mobile communication device includes monitor hardware operative monitor for presence of a repetitive pattern present in received wireless communications present in a network environment. Depending on a magnitude of wireless energy of a portion of received wireless communications including the repetitive pattern, communication management hardware of the wireless station controls transmission of wireless communications from the wireless station. Thus, depending on a detected energy level of the monitored wireless signals having a particular signature (such as the repetitive pattern), the mobile communication device controls subsequent transmission of wireless communications from the mobile communication device in the network environment.

Abstract: According to one configuration, a system includes user equipment in communication with a wireless base station. The user equipment receives resource allocation information facilitating communication of wireless communications in a network environment. The user equipment is operable to: produce a first configured grant communication to include: i) first information specifying attributes (such as a first selected identifier value) of the first configured grant communication, and ii) second information specifying attributes (such as a second selected identifier value) of a second (buffered) configured grant communication to be communicated from the user equipment to the wireless base station after communication of the first configured grant communication to the wireless base station. The user equipment communicates the first configured grant communication to the wireless base station and then follows up with communication of the second configured grant communication to the wireless base station.

Abstract: A base station schedules a user equipment (UE) for uplink air link resources, e.g., unlicensed spectrum PUSCH resources, corresponding to one or more slots and, in some embodiments, at least one mini-slot. There may be, and sometimes are gaps between two scheduled slots and/or between a scheduled slot and a scheduled mini-slot. Different uplink air link resources corresponding to a schedule slot or mini-slot may, and sometimes do, use different set of frequencies. The base station generates and sends to the UE a single UL grant which grants uplink air link resources corresponding to the composite of resource allocations corresponding to the one or more slots and, in some embodiments, at least one mini-slot. The single UL grant may, and sometimes does, communicates gap information and frequency information.

Abstract: Methods and apparatus used to facilitate preparation of one or more target base stations for possible UE handoffs, e.g., conditional handoffs, which may or may not occur depending on whether or not various handoff conditions are satisfied are described. A handoff message, e.g., a conditional handoff message, including a validity time is generated and sent to each selected target base stations to which a UE may be handed off. The validity time indicates to the target base station a time window, e.g., a time duration for which the handoff target message is to be considered valid. In response to the handoff message, the target base station, receiving the handoff message, allocates resources to the UE and starts a countdown validity timer based on the indicated length of the validity time. When the validity timer expires without handoff to the target base station, the target base station releases the allocated resources.

Abstract: Efficient paging in a communications system including macro and small cell base stations is described. A macro cell base station receives, from a network node, a request to page a UE and determines a set of base stations including one or more small cell base stations, which are to attempt to page the UE. The macro cell base station communicates the paging request to the selected one or more small cell base stations. A small cell base station, using unlicensed spectrum, may fail in its paging attempt due to current unavailibity of the unlicensed spectrum (LBT fails to clear) resulting in no paging signal transmitted; the reason for failure is communicated from the small cell base station to the macro cell base station via a paging response message. The macro cell base station in turn communicates a paging response message to the network node communicating the reason for failure.

Abstract: Methods and apparatus for efficient paging in a communications system using unlicensed spectrum are described. A base station, which uses unlicensed spectrum, receives a paging request message from a network node and performs paging operations attempting to page the UE. The paging attempt may fail due to the base station being unable to transmit a paging signal to the UE because the unlicensed spectrum is currently unavailable or because the UE did not respond to a transmitted page. The base station generates and transmits a paging failure response message including a failure cause code indicating the reason that the paging attempt failed. The network node receives the paging failure response message, recovers the failure cause code, and implements a paging escalation strategy as a function of the recovered failure cause code.

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: 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. The priority information identifies which particular stations are authorized to be a guest station corresponding to a particular transmission opportunity.

Abstract: A first wireless communications device, e.g., a first UE, shares a second portion, e.g., a remaining unused portion, of its sidelink (SL) channel occupancy time (COT), corresponding to unlicensed spectrum, with a second wireless communications device. The first wireless communications device communicates SL COT sharing information to the second wireless communications device via sidelink control information (SCI) communicated over physical sidelink control channel (PSCCH) resources during a first portion of its SL COT. In some embodiments, the SL COT sharing information includes one or more of: i) a channel access priority class value, ii) a COT-sharing indicator value, or iii) a COT duration field value. The SL COT sharing information allows the second wireless communications device to identify the second portion of the COT, which the second wireless communications device is allowed to use for reverse transmission to the first wireless communications.
