Abstract: A first communications device including a transmitter, such as a base station or UE, identifies a first packet flow for which end to end packet retransmission is supported. The first communications device assigns said first packet flow to a Hybrid Automatic Repeat Request (HARQ) process which does not require generation of acknowledgements (ACKs) or negative acknowledgements (NAKs) from a device receiving data corresponding to said first packet flow; and transmits data corresponding to said first packet flow to a second communications device. In some embodiments, the HARQ process to which the first packet flow is assigned is a dedicated HARQ suppression process. In some embodiments, the HARQ process to which the first packet flow is assigned is a HARQ process which has been temporarily designated as a HARQ suppression process. HARQ suppression is applied for the first packet flow at a radio link layer and/or MAC layer.

Abstract: A user equipment has been allocated uplink resources, e.g. interlaced uplink channel resources, e.g. interlaced physical uplink shared channel (PUSCH) resources, and non-interlaced uplink channel resources. The UE receives cancellation indication (CI) information which rescinds the allocation for a portion of the previous granted resources. CI is communicated using different formats for resources which are in blocks and resources which are interlaced. The CI for the interlaced resources uses a more efficient format with less overhead to communicate frequency information corresponding to the cancellation for the interlaced channel.

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: Apparatus and methods for multi-carrier or multi-band utilization in an unlicensed wireless network. In one embodiment, the apparatus and methods provide enhanced wireless services which provide enhanced bandwidth capability to 5G NR-U entities such as gNodeB and UE devices across two heterogeneous unlicensed bands having different medium access mechanism and protocols. In one variant, LBT (listen before talk) protocols are used to detect the presence or absence of users within the respective bands of interest. When two or more unoccupied carriers or bands are identified, aggregated operation is used ti enhance the downlink/uplink (DL/UL) transmission bandwidth for the device(s).

Abstract: Apparatus and methods for streamlined cell activation in a wireless network. In one embodiment, the apparatus and methods provide enhanced wireless services which utilize bandwidth-efficient setup/configuration messaging and cell activation, including for very large numbers of cells, and which do not overwhelm data backhaul(s) associated with wireless nodes used for communication. In one embodiment, a message protocol is used wherein a prescribed number of cells of a given DU (e.g., all, a prescribed subset, etc.) are activated without having to enumerate or include specific data relating to the cells being activated. In one variant, this “global” activation is conducted using an Activate All Cells IE (Information Element) disposed with the F1SETUP RESPONSE message issued by a controlling CU entity within a 5G-NR infrastructure. In other variants, cells of multiple DUs can be controlled simultaneously, such as via distribution of a system-wide global activation IE.

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 unavailability 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 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.
