Abstract: A method for operating a user equipment (UE) includes detecting a failure of a first link between the UE and an access node, and based thereon, detecting a second link between the UE and the access node, sending, to the access node, a beam failure recovery request (BFRQ) on one or more physical random access channel (PRACH) resources associated a third link conveying a reference signal, wherein the third link and the second link are quasi co-located (QCLed), wherein the BFRQ includes a group identifier associated with a UE group including the UE, and monitoring one or more PRACH response opportunities associated with the one or more PRACH resources for a beam failure recovery response (BFRP).

Abstract: An embodiment method defines a demodulation reference signal (DMRS) pattern for transmitting DMRSs for rank 3 or rank 4 transmissions. The DMRS pattern specifies 12 REs in total per physical resource block (PRB) for carrying DMRSs on three or four antenna ports in antenna ports 7-14 for rank 3 or rank 4 transmissions. DMRS settings for transmitting DMRS according to the DMRS pattern may be specified using a downlink control information table.

Abstract: A method for operating a user equipment (UE) includes detecting that a beam failure has occurred, and based thereon, transmitting a first beam failure recovery request (BFRR) message at a first transmit power level on a first channel resource in a channel with a transmit power control mechanism configured to set the first transmit power level different from a first non-BFRR transmit power level of a first non-BFRR message transmitted on the first channel resource in the channel.

Abstract: A method for scheduling multiple users for multi-user full duplex communications in a wireless network over a wireless channel. The scheduling may be based on base station beam indices, base station channel measurements, received UE capabilities, received UE measured channel conditions and/or received UE positional information. In another embodiment, the scheduling of the UE full duplex time slots may be updated based on base station channel interference measurements, received UE measured channel interference, the received UE measured channel conditions, and/or received UE positional information updates.

Abstract: A method is provided for radio link failure (RLF) operations based on link failure recovery (LR), beam failure recovery (BFR) and radio link monitoring (RLM), and for interactions between modules for RLF, BFR, and RLM, and for integration of indications. A device may measure a reference signal received over one or more communication paths of a radio link to estimate the link quality for radio link operations (BFR/LR) and RLM. Based on configured criteria, the device may generate RLM or BFR/LR indications based on an assessed link quality metric or a link recovery operation status, combine or filter the indications and metrics from multiple paths of each module or from multiple modules, and send the filtered or combined results from a physical layer of the device to assist the RLF operations.

Abstract: A method for operating a user equipment (UE) includes detecting that a first request type of a first request is not a beam failure recovery request (BFRQ) and based thereon, selecting a first random access resource for transmitting the first request, wherein the first random access resource is selected from a first subset of one or more random access resources, and wherein random access resources in the first subset are associated with a communications beam serving the UE, and transmitting, by the UE to an access node, the first request in the first random access resource.
