Abstract: A user equipment (UE) and a base station exchange communications to enable the UE to switch beams. The UE receives a physical uplink control channel (PUCCH) resource configuration from the base station, wherein the PUCCH resource configuration includes a plurality of PUCCH resources, receives a signal from the base station based on which one of the plurality of PUCCH resources is activated, performs a beam switching operation to change a transmission beam to a beam corresponding to the activated PUCCH resource and transmits periodic uplink (UL) data using the beam corresponding to the activated PUCCH resource.

Abstract: A reduced capacity (redcap) device may perform initial uplink communications, including transmitting a redcap physical uplink control channel (R-PUCCH), over an initial uplink bandwidth part (BWP) shared with a second device, the initial uplink BWP having a bandwidth (BW) larger than a maximum BW supported by the redcap device and smaller than or equal to a maximum BW supported by the second device. Frequency hopping operation for the redcap device may be supported for the R-PUCCH transmission through frequency division multiplexing and/or time division multiplexing settings for the resources used for the R-PUCCH transmission, and for PUCCH transmission by the second device. Restrictions may be implemented to create a gap for redcap devices to perform RF retuning between a physical RACH transmission and a subsequent physical control channel (e.g. PDCCH) monitoring for random access reception when the frequency gap is larger than the maximum BW supported by the redcap device.

Abstract: Devices, systems, and methods for Random Access Channel (RACH) configuration in Layer 1 (L1)/Layer 2 (L2) mobility. A user equipment (UE) may obtain a downlink (DL) Transmission Configuration Indicator (TCI) list from a first Transmission and Reception Point (TRP). The DL TCI list may include DL beam information, RACH Occasion (RO) information, and initial Bandwidth Part (BWP) information associated with each DL TCI of a plurality of DL TCIs related to the first TRP and multiple TRPs adjacent to the first TRP. The UE may receive a handover command from the first TRP via Downlink Control Information (DCI) in Li or Media Access Control (MAC) Control Element (CE) in L2. The handover command indicates a handover from the first TRP to a second TRP of the multiple TRPs for the UE, and includes a specified DL TCI related to the second TRP. The UE may determine RACH information related to the second TRP, based at least partly on the specified DL TCI related to the second TRP included in the handover command and the DL TCI list. The UE may then perform random access to the second TRP based on the RACH information related to the second TRP. The RACH information may include uplink (UL) beam information, RO information and Bandwidth Part (BWP) information for the UE to perform random access to the second TRP.

Abstract: Enhancements for a physical downlink shared channel (PDSCH) antenna ports indications for demodulation reference signal (DMRS) Type 2 with frequency domain orthogonal cover code length 4 are disclosed herein. Various embodiments herein relate the use of additional and/or replacement DMRS ports (e.g., for PDSCH) in an enhanced wireless communication system as compared to DMRS ports that may be used in legacy wireless communication systems. Various applicable scenarios are discussed. Various mechanisms for determining the additional and/or replacement DMRS ports with respect to the various discussed circumstances are also discussed.

Abstract: Aspects are presented herein of apparatuses, systems, and methods for measurement gap configuration. A cellular network may establish communication with a UE using a first and second cell. The cellular network may configure bandwidth parts (BWPs) for the first and second cell, including a first and second BWP for the first cell and a third and fourth BWP for the second cell. A measurement gap configuration that specifies when the UE is to use a first measurement gap pattern may be provided to the UE. At a first time, the cellular network may communicate with the UE using the first BWP for the first cell and the third BWP for the second cell, based on the first measurement gap pattern. At a second time, the cellular network may communicate with the UE using the second BWP for the first cell based on a modification of the first measurement gap pattern.

Abstract: A base station and wireless communication (UE) may perform type II CSI-RS port selection based at least on partial reciprocity between an uplink path and a downlink path between the base station and the UE. The base station may identify dominant signal paths between the base station and the UE, based on measurements performed during uplink transmissions, and may transmit, to the UE, corresponding information indicative of CSI measurement and reporting configuration that may include a single measurement resource or multiple measurement resources. Each measurement resource may include multiple-port CSI-RS ports. The UE may indicate, to the base station, selection of a measurement resource when multiple measurement resources are configured, and may also report layer independent or layer common selection of a subset of CSI-RS ports included in the indicated single measurement resource or multiple measurement resources. Further enhancements include frequency domain compression enhancement and dynamic codebook parameter reconfiguration.

Abstract: A user equipment (UE) is configured to change a transmission configuration indicator (TCI) state. The receives, from the base station, a network flag indicating a transmission configuration indicator (TCI) state change configuration for the network, determines a time span for continuing to use a current TCI state prior to switching to a new TCI state based on the network flag and switches to the new TCI state after the time span.
