Abstract:
A method and apparatus are described for providing triggering services over multiple access networks. A triggering service server (TSS) architecture includes a triggering identity function (TIF) which maintains a database of device and application identifier mappings across multiple access networks, triggering capabilities and triggering preferences. The TSS also includes a triggering decision function (TDF) that uses information from the TIF and determines how triggers should be performed towards a device and/or an application hosted on a particular device. The TSS also includes triggering gateways (T-GWs) that perform triggering in different domains. A “not-registered-triggerable” state may be used to indicate whether an entity, such as a device, application or user can receive triggers although it is not registered in a specific access network. Methods and apparatus are also described for implementing various unassisted triggering and assisted triggering procedures using wireless transmit/receive units (WTRUs), application servers (ASs) and service capability servers (SCSs).

Abstract:
In NR, a slot structure of a UE may be dynamic due the number of symbols of PDCCH and whether the slot has UL data, among other considerations. Additionally, to support multi-TRP/multi-panel/multi-BWP operation, a UE may be configured with multiple TRSs, and when a UE needs to receive multiple TRSs in the same slot, efficient signaling of the TRSs is important because of the high overhead involved. During a transmission, a UE may need to do beam switching when there is a beam failure, but existing systems do not have mechanisms for the UE to synchronize time and frequency with a new beam. Further, when a UE switches to a new beam, the effect on scheduled TRS transmission for old beams is unclear. Fine frequency and time tracking may also be required during an initial access procedure. Existing NR systems do not address how a UE may perform time and frequency tracking during an initial access procedure. Additionally, URLLC data may need to be transmitted to a UE immediately in an NR system. Existing NR systems do not address sending a TRS to a UE with URLLC data. Embodiments described herein address these and other issues.

Abstract:
A first user equipment (UE) transmits, to a second UE, a transmission configuration indicating first timing information for a discontinuous reception (DRX) configuration for sidelink transmission from the first UE. The first UE transmits, to the second UE, a reception configuration indicating second timing information for the DRX configuration for sidelink reception by the first UE. The first UE receives a response from the second UE confirming or rejecting the DRX configuration.

Abstract:
PBCH design may affect timing indication in a wireless network and polar code interleaver design, among other things. Mechanisms may indicate half frame timing though de-modulation reference signal sequence initialization, de-modulation reference signal mapping order, or de-modulation reference signal resource element location.

Abstract:
Systems and methods for PDCCH reliability are disclosed. The PDCCH may be improved by introducing multi-TRP, multi-beam or repeated, PDCCH transmission and reception. In some methods and systems, PDCCH is transmitted on multiple CORESETs (Control Resource Set), where each CORESET is associated with a TCI state. In some cases, it is beneficial if a UE can determine that multiple received DCIs are duplicates, in order not to duplicate the corresponding UE action. Methods and systems for DCI duplication determination are disclosed. In some methods and systems, PDCCH is transmitted in a single CORESET, where the CORESET is associated with multiple TCI states. Various ways to apply the different TCI states to different disjoint frequency parts of the CORESET or the whole CORESET are proposed. Furthermore, the TCI state used for PDCCH may be used for subsequent PDSCH reception as well, in some cases. The disclosure also presents methods and systems on how to apply multiple TCI states of a received PDCCH to a subsequent PDSCH reception.

Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a user equipment (UE) may transmit, over an unlicensed carrier, an initial transmission of a transport block (TB) satisfying a condition and an indication that a retransmission of the TB will be communicated over a licensed carrier. The apparatus may retransmit the TB over the licensed carrier based at least in part on a failure of the transmission of the TB over the unlicensed carrier. Numerous other aspects are described.

International Classification:
H04W 52/02
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one of a transmission profile, of an application executing on the UE, that indicates whether sidelink discontinuous reception (DRX) is required, or a sidelink communication that indicates whether sidelink DRX is supported. The UE may communicate with one or more other UEs in accordance with a configuration for sidelink DRX, or with sidelink DRX disabled, based at least in part on the transmission profile or the sidelink communication. Numerous other aspects are described.

Abstract:
Methods and apparatuses are described herein for transmission priority, collisions, and sharing in the COT by frame based equipment (FBE). In accordance with one embodiment, a wireless communications device such as an FBE, may conduct two stage channel sensing to avoid collision between other FBEs nodes. The wireless communications device may adjust the energy threshold to reflect a channel access priority. The FBE may conducting continuous and non-continuous second stage channel sensing. The FBE may perform enhanced two stage channel sensing to exploit the remaining portion of the COT. The FBE may store a configuration for the second stage of channel sensing for both the downlink (DL) and uplink (UL).
