Abstract: A user equipment (UE) may be scheduled as part of a group of UEs. The UE receives a radio network temporary identifier (RNTI) associated with the group of UEs that includes the UE. The UE receives a signal from one of a cell on which the UE is currently camped or a cell to which the UE is currently connected, the signal scrambled by the RNTI and including control information. The UE decodes the signal using the RNTI and performs an operation in response to the control information.

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) in multiple component carriers (CC). The UE determines if the UE is operating in carrier aggregation (CA) mode having a first CC in a first frequency band and a second CC in a second frequency band. When the UE is operating in CA with a first CC in the first frequency band and the second CC in the second frequency band, the UE determines a span pattern for PDCCH symbols being received on the first and second CC and selects a PDCCH monitoring type based on, at least, the span pattern. A UE also determines if a first CC and a second CC of a CA combination are collocated and selects a PDCCH monitoring type based on, at least, the determination of whether the first and second CC are collocated.

Abstract: User equipment (UE) operation in a single frequency network (SFN). The UE may receive one or more transmission configuration indication (TCI) states corresponding to one or more downlink resources, receive a demodulated reference signal (DMRS) wherein the DMRS is quasi co-located (QCLed) with one or more channel state information reference signal (CSI-RS) from multiple cells of a SFN and quasi co-location (QCL) information is included in the one or more TCI and determine a time and frequency offset corresponding to each of the multiple cells based on the CSI-RS.

Abstract: A user equipment (UE) communicates with a further UE via a sidelink and communicates with a cell of a network via an uplink. The UE receives a hybrid automatic repeat request (HARQ) acknowledgement (ACK) timing parameter from the network, generates a sidelink HARQ-ACK codebook based on a signaling exchange with the further UE, wherein the sidelink HARQ-ACK codebook is constructed in decreasing order of one or more physical sidelink shared channel (PSSCH) transmission slots associated with a configured physical sidelink feedback channel (PSFCH) occasion, and transmits an indication of the sidelink HARQ-ACK codebook to the cell of the network.

Abstract: Some embodiments include a system, method, and computer program product for managing beam switching at a higher subcarrier spacing (SCS) at millimeter wavelength (mmWave) frequencies in a 5G wireless communications system. A user equipment (UE) transmits a beam switching gap (BSG) capability to a 5G Node B (gNB). The UE receives a transmission configuration indicator (TCI) state from the gNB, and performs a beam switch to the TCI state corresponding to a first beam. The UE can receive a first control resource set (CORESET) on the first beam and a second CORESET on a second beam where the BSG occurs between the first CORESET and a second CORESET. The UE can perform beam switching within the BSG from the first beam to a second beam, and receive the second CORESET on the second beam. The UE can determine and transmit modified candidate values of beam switching parameters to the gNB.
