Abstract: A system and a method are provided in which a user equipment (UE) acquires, from a base station (BS), a first timing advance (TA) value for a first transmission and reception point (TRP) and a second TA value for a second TRP via random access channel (RACH) signaling based on an identifier. The UE manages the first TA value and the second TA value during multi-TRP transmission within a cell having the first TRP and the second TRP.

Abstract: A system and a method are disclosed to manage beams in a Multicast and Broadcast Services (MBS) wireless communication network. A first device receives a Physical Downlink Control Channel (PDCCH) and a Physical Downlink Shared Channel (PDSCH) for MBS communications in a Common Frequency Resource (CFR). The first device also receives a configuration sent by the second device that is for a MBS Beam Failure Detection Reference Signal (BFD-RS). The first device may then detect a MBS Beam Failure Incident (BFI) of a first MBS beam using the MBS BFD-RS configuration. In response to detecting the BFI, the first device may autonomously connect to a second MBS beam. Alternatively, the first device may communicate the BFI to the second device in order to recover a MBS beam. In one embodiment, the first device is a User Equipment (UE), and the second device is a Next Generation NodeB (gNB).

Abstract: A system and a method are disclosed. The method includes configuring the UE with a first UL subband configuration for communicating with an external device, wherein the first UL subband configuration designates a first set of one or more resource blocks (RBs) inside of a carrier for the UE to perform UL transmission, receiving a downlink (DL) signal indication, and overriding the first UL subband configuration with a second subband configuration based on the DL signal indication, wherein the second subband configuration designates a first communication configuration of the first set of one or more RBs inside of a subband and a second communication configuration of a second set of RBs outside of the subband.

Abstract: A system and a method are disclosed for PRACH for coverage enhancements. In some embodiments, the method includes: transmitting, by a User Equipment (UE), a first Physical Random Access Channel (PRACH) transmission in a first Random Access Channel Occasion (RO); and transmitting, by the UE, a second PRACH transmission in a second RO, the second PRACH transmission being a repetition of the first PRACH transmission, the second RO having an index differing from an index of the first RO by a set integer.

Abstract: A system and a method are disclosed for dynamic spectrum sharing. In some embodiments, the method includes: processing, by a User Equipment (UE), a first transmission overlapping, in an orthogonal frequency division multiplexing (OFDM) symbol and in a Resource Block (RB), a Long Term Evolution Cell Specific Reference Signal (LTE CRS) transmission, the first transmission including: a Physical Downlink Control Channel (PDCCH) Demodulation Reference Symbol (DMRS) transmission, or a Physical Downlink Shared Channel (PDSCH) DMRS transmission, or a PDCCH data transmission.

Abstract: A system and a method are disclosed for providing enhancements to Semi-Persistent Scheduling (SPS) to match traffic, while also providing power savings, resource utilization and HARQ enhancements related to traffic and SPS configurations. A SPS configuration may include one or more occasions in a Physical Downlink Shared Channel (PDSCH) of a wireless network for traffic for a wireless device. In response to the SPS configuration, the wireless device receives the traffic in the scheduled occasions. The SPS configuration may include one or more occasions in at least one time slot in a SPS period. At least one occasion may align with a target periodicity of the traffic. The SPS configuration may include different configuration states, and a Downlink Control Information (DCI) message may be used to indicate to a wireless device which SPS configuration state to use to receive the traffic.
