Abstract: A system and a method are disclosed for beam refinement to enable inactive mode transmission in frequency range 2 for 3GPP RedCap devices. A RedCap device receives system information in a SIB1 from a wireless network in which the SIB1 includes information relating to an indication of resources used to transmit a SIB-x. The device receives the SIB-x, which includes an indication of at least one resource, at least one configuration for a Downlink-Reference Signal (DL-RS) transmission, and information relating to a measurement report relating to the beam-refinement measurement that is to be performed by a device. The device receives the DL-RS transmission from the wireless communication network, performs the beam-refinement measurement, and sends a measurement report to the wireless network. Subsequent to sending the measurement report, the device sends an enhanced transmission to the wireless network based on the measurement report.

Abstract: A system and a method are disclosed relating to a transport block processing chain for a transmitter. A code block determination circuit may be configured to determine a size of a code block that maps across multiple slots of a wireless physical shared channel according to a Transport Block over Multiple Slots (TBoMS) configuration, and a rate matching circuit may be configured to rate match bits of the code block to a number of bits available in a transport block that spans the predetermined number of slots of the wireless physical shared channel. Additionally, an interleaver may be configured to interleave a continuous output of the rate matching circuit on a slot basis so that a code block that crosses a slot boundary between a first slot and a second slot is interleaved within the first slot and the second slot.

Abstract: A method may include sending a contention resolution message for a random access procedure from a user equipment (UE) through a physical uplink channel in a wireless communication network, and sending a repetition of the contention resolution message from the UE through the physical uplink channel. The physical uplink channel may include a physical uplink shared channel (PUSCH). The method may further include selecting a preamble from a first preamble group corresponding to a capability of the UE to send the repetition of the contention resolution message, and sending the preamble from the UE. Selecting the preamble from the first preamble group may include selecting a preamble from a first preamble sub-group corresponding to the capability of the UE to send the repetition of the contention resolution message.

Abstract: A system and a method are disclosed for improving resource selection schemes is provided. In an embodiment, Scheme 2 resource selection is improved by using a Sidelink Feedback Channel (PSFCH) resources to identify specific instances of conflicts in a periodic reservation of a resource. In an embodiment, Scheme 1 resource selection is improved by allowing a user equipment (UE) to include non-preferred resources in a candidate resource set based on one or more conditions and/or subject to one or more limitations. In an embodiment, condition triggered resource selection assistance is improved by restricting a UE from sending resource selection assistance information unless a second condition is satisfied.

Abstract: An apparatus and method are provided for performing a subband operation for cross division duplex (XDD) technology to enhance coverage in wireless communication systems. A method includes identifying, by a user equipment (UE), an uplink (UL) or downlink (DL) subband configuration provided from a gNB to the UE, and determining a priority between a UL transmission and a DL reception based on whether a collision between DL and UL operations occurs in a time domain, wherein the UE is a half-duplex UE which performs the UL transmission at different times than when the UE performs the DL reception.

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.
