Abstract: Embodiments of a User Equipment (UE) to operate in accordance with a physical random access channel (PRACH) are disclosed herein. The UE may comprise hardware processing circuitry to determine a coverage enhancement category for the UE based on downlink channel statistics related to reception of downlink signals at the UE from an Evolved Node-B (eNB) and an uplink-downlink imbalance parameter related to uplink reception at the eNB. The hardware processing circuitry may be further to select, for use in a coverage enhancement mode, a PRACH preamble from a set of candidate PRACH preambles based on the determined coverage enhancement category for the UE. In some embodiments, at least some of the candidate PRACH preambles may span a different number of sub-frames.

Abstract: Configuring channel state information reference signal (CSI-RS) reporting at a network may include encoding a channel state information (CSI) reporting configuration communication for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) and a second TRP. The CSI reporting configuration may include a first group of CMR (Channel Measurement Resource) resources for the first TRP, and a second group of CMR resources for the second TRP. A CSI measurement communication received from the UE, may be measurements based on the CSI-RS reporting configuration communication. Based on the CSI measurement communication, one or more downlink data transmissions may be scheduled.

Abstract: A base station serving a user equipment (UE) may signal a transmission configuration indicator (TCI) state change for more than one control resource set (CORESET). The base station has one or more processors configured to configure, for the UE, a group of control resource sets (CORESETs), the CORESET group including a plurality of CORESETs, signal, to the UE, the CORESET group including the plurality of CORESETs and indicate, to the UE, a transmission configuration indicator (TCI) state change for one or more of the plurality of CORESETs in the CORESET group via a medium access control (MAC) control element (CE).

Abstract: Techniques discussed herein can facilitate listen before talk procedures for clear channel assessment signaling. One example aspect is a baseband processor of a user equipment (UE), including one or more processors configured to receive system information including a region indication for clear channel assessment (CCA) procedures. The CCA procedures are associated with a listen before talk (LBT) region configuration for one of a first region, a second region, or a third region. One or more processors are configured to receive a downlink control information (DCI) in a physical downlink control channel (PDCCH) message that includes a DCI CCA indication. Subsequently, the one or more processors are configured to perform an initial LBT procedure associated with the region indication and generate a random access channel (RACH) message after performing the initial LBT procedure. Finally, the one or more processors generate an uplink (UL) message according to the DCI CCA indication.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations for resource allocation for contiguous resource block transmission. In one aspect, the operations can include actions of identifying a set of sub-channels that are not suitable for serving as leading sub-channels for Physical Sidelink Control Channel (PSCCH) and Physical Sidelink Shared Channel (PSSCH) transmission, and excluding the identified set of sub-channels from a candidate set of resources.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing downlink transmission and interlace uplink transmission. For example, some aspects of this disclosure relate to a base station including a transceiver configured to communicate over a wireless network with a user equipment (UE) and a processor communicatively coupled to the transceiver. The processor divides a plurality of candidate Synchronization Signal Block (SSB) positions in a time window into a plurality of groups and communicates, using the transceiver, information associated with the plurality of groups of candidate SSB positions to the UE. The processor further performs a listen-before-talk (LBT) procedure. In response to the LBT procedure being successful, the processor determines a first group of the plurality of groups and transmits, using the transceiver, one or more SSBs on one or more candidate SSB positions of the first group to the UE.

Abstract: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may receive, from a base station, an indication of parameter settings of a port selection codebook. The port selection codebook includes a port selection matrix W1, a combinational coefficient matrix W2, and a frequency basis selection matrix Wf. Based at least in part on the parameter settings, the UE selects L CSI-RS ports, Mv frequency basis from a window of N consecutive frequency basis; and up to beta*L*Mv entries per layer, where beta is a percentage of the L*Mv entries per layer. The UE reports one or more of the port selection matrix W1, the up to beta*L*Mv entries in the combinational coefficient matrix W2 per layer, and the frequency basis selection matrix Wf to the base station.
