Abstract: A communication system, a method, and one or more non-transitory computer-readable storage devices allowing joint a user equipment to perform initial access with terrestrial and non-terrestrial communication nodes of a service area. The service area is partitioned into terrestrial initial-access zones and non-terrestrial initial-access zones with each terrestrial initial-access zone associated with one or more of the terrestrial communication nodes and each non-terrestrial initial-access zone associated with at least one of the non-terrestrial communication nodes. The user equipment uses positioning reference signals from positioning anchors to determine its location, determine a zone from the terrestrial and non-terrestrial initial-access zones based on the location, select one of the terrestrial and non-terrestrial communication nodes based on the determined zone, and establishing communication with the selected communication node.

Abstract: A method that includes sensing, by a first user equipment (UE), a signal transmitted by a second UE indicating a resource reservation for a shared channel for a sidelink (SL) transmission by the second UE and a priority associated with the SL transmission; determining, by the first UE, a threshold based on a type of the SL transmission and the priority; and selecting, by the first UE, a resource in the shared channel to use for a SL transmission by the first UE based on the threshold.

Abstract: A method embodiment includes receiving, by a network device, a cooperation candidate set (CCS) and determining a cooperation active set (CAS). The CCS includes a plurality of potential cooperating user equipment (CUEs) for selection to the CAS, and the plurality of potential CUEs is selected from a plurality of user equipment (UEs) in the network. The CAS is a set of CUEs selected from the CCS. A target user equipment (TUE) and the set of CUEs form a virtual multipoint transceiver.

Abstract: Systems and methods for sidelink configuration are provided. A transmitting user equipment (UE) transmits configuration parameters relating to a sidelink transmission between the UE and a second UE via higher-layer signalling and then transmits the sidelink transmission to the second UE. The higher layer signalling is a layer above the sidelink transmission. The parameters may include feedback channel parameters or parameters for sidelink reference signal transmission by the second UE. The parameters may be selected by the transmitting UE, or they may be received initially from the network. The parameters may be part of a sidelink configured grant configuration (SL CG) signalled to the second UE. The sidelink transmission may be a configured-grant transmission to the second UE according to the SL CG configuration. The higher layer signalling may be PC5 signalling or RRC signaling.

Abstract: A New Radio (NR) control signal that indicates one or more Long Term Evolution (LTE) network parameters may be transmitted to NR UEs to enable the NR UEs to identify which resources carry LTE signal(s). The NR UEs may then receive one or more NR downlink signals over remaining resources in a set of resources without processing those resources that carry LTE signal(s). The NR downlink signals may have a zero power level, or otherwise be blanked, over resources that carry the LTE signal(s).

Abstract: In accordance with embodiments, methods for data communications are disclosed. A device obtains a forward error correction (FEC) encoded bit stream. The device maps the FEC encoded bit stream to produce a set of symbols according to a bit-to-symbol mapping rule. The bit-to-symbol mapping rule comprises a first mapper bit position associated with a first mapper error protection level and a second mapper bit position associated with a second mapper error protection level. The first mapper error protection level is greater than the second mapper error protection level. The device then transmits the set of symbols in the communications system.

Abstract: Resource usage information is determined at a first UE about usage of a first communication resource by other UEs based on signals received by the UE. The first communication resource is excluded from a set of candidate communication resources when the resource usage information exceeds a usage threshold. When the first communication resource is excluded, a second communication resource from the candidate communication resources remaining in the set is selected to use for a transmission by the UE.
