Abstract: Some embodiments include an apparatus, method, and computer program product for simultaneous multiple secondary cell (SCell) fast activation in a wireless communications system. Some embodiments include a user equipment (UE) that can simultaneously activate multiple SCells. In some embodiments, after receiving an activation command, the UE can receive two or more temporary reference signals (T-RSs) which are user equipment (UE) specific reference signals. The UE can use the T-RSs for fine time/frequency (T/F) tracking and Automatic Gain Control (AGC) adjustment of corresponding SCells resulting in reduced SCell activation latency compared to utilizing a Synchronization Signal (SS)/Physical Broadcast Channel (PBCH) Block Measurement Timing Configuration (SMTC).

Abstract: An approach is described for a dynamic off period of a base station within a wireless communication environment and a process for notifying a UE of the same. In a first scenario, the DCI message is modified with newly-defined values indicative of the different power saving states (i.e., “dynamic off states”) of the base station. These power saving states may defined as suspending one or both of downlink transmission and uplink reception. In another scenario, a new notification message is defined. In either case, the notification signal may also include cell and/or beam specific parameters as well as an application delay that defines a start time of the dynamic off period.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing channel state information (CSI) reporting that includes a stale CSI report. Based at least in part on a CSI reporting configuration, a user equipment (UE) performs CSI measurements during a current reference time period, and generates one or more CSI reports including at least a stale CSI report. A stale CSI report is generated based at least in part on CSI measurements performed prior to the current reference time period. The UE further generates an uplink message including the one or more CSI reports, and transmits the uplink message to the base station under a reporting setting determined by the CSI reporting configuration.

Abstract: Some embodiments include a system, method, and computer program product for radio resource management (RRM) scaling factor enhancement without measurement gaps (MGs) in an E-UTRA-New Radio (NR) Dual Connectivity (EN-DC) network. Some embodiments include a user equipment (UE) that receives from a Primary Node (PN), a first NR measurement object (MO) without MG associated with a frequency. The UE receives from a Secondary Node (SN), a second NR MO without MG associated with the same frequency. The UE allocates resources based on a Primary Secondary Component Carrier (PSCC) and determines a scaling factor for determining a total procedure period for obtaining measurements to satisfy the first and the second NR MO without MG. Some embodiments include combining counts of NR MO without MG at a same frequency. Some embodiments include coordination between the PN and the SN so that MOs without MG at a common frequency satisfy the merging rule.

Abstract: A user equipment (UE) is configured to operate as a relay UE between a remote UE and a base station. The relay UE receives, from an originating device, a data packet for relay to a recipient device, determines that the relay of the data packet to the recipient device has failed and sends, to the originating device, a transmission including the data packet, wherein the transmission comprises an indication that the data packet is being returned to the originating device.

Abstract: Systems, methods and devices can are provided, which can include configuring one or more bandwidth parts for a secondary cell (SCell) that is in communication with a user equipment (UE). A base station transmits to a UE a first radio resource control (RRC) message including one or more configuration parameters for a first bandwidth part (BWP) associated with a secondary cell (SCell). The UE communicates a first message with the SCell via the first SCell BWP. The UE receives a second RRC message indicating a change from the first SCell BWP to a second SCell BWP to be used for SCell communications. The UE communicates a second message with the SCell via the second SCell BWP.

Abstract: A next generation evolved Node B (gNB) configured to provide an unlicensed bandwidth for communications with a user equipment (UE) performs a listen-before-talk procedure to determine an occupation state of busy or idle for the unlicensed bandwidth. When the occupation state is determined by the gNB to be idle, the gNB signals the UE, via a downlink control indicator (DCI), to conduct a channel access measurement (CAM) on the unlicensed bandwidth, the measurement comprising at least one of an energy detection measurement or a signal quality measurement. A measurement report is received from the UE comprising an indication of the occupation state of the unlicensed bandwidth as determined by the UE.

Abstract: The exemplary embodiments relate to determining which instance of control information is to be used for transmitter beam selection. A user equipment may receive a medium access control (MAC) control element (CE) that includes first control information associated with transmitter beam selection, transmit an acknowledgement (ACK) to the network in response to receiving the MAC CE and receive a downlink signal over a physical downlink control channel (PDCCH) that schedules an uplink transmission. The downlink signal is received prior to an expiration of a predetermined duration relative to transmitting the ACK and includes second control information associated with transmitter beam selection. The UE may also transmit an uplink signal based on the scheduled uplink transmission. The UE selects a transmitter beam for the uplink signal based on one of the first control information or the second control information.

Abstract: A user equipment (UE) is configured for half-duplex operations with a network. The UE determines that half-duplex (HD) frequency division duplex (FDD) is enabled by a network with which the UE is communicating, wherein a guard period is configured for downlink and uplink switching when the HD FDD is enabled, performs a first uplink transmission at a first time and performs a first downlink reception at a second time, wherein the guard period represents a time duration between the first time and the second time during which the UE is not to perform a second different uplink transmission or a second different downlink reception.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing transmission of nominal repetitions of data over an unlicensed spectrum. One or more nominal repetitions of data are to be transmitted by a user equipment (UE) over an unlicensed spectrum used for both uplink and downlink transmissions. The one or more nominal repetitions of the data are segmented into multiple actual repetitions of portions of the data. The UE identifies an orphan symbol in an actual repetition of the multiple actual repetitions of portions of the data, and determines a filler symbol to replace the orphan symbol in the actual repetition. In addition, the UE transmits the multiple actual repetitions including the filler symbol in replacement of the orphan symbol to a base station over the unlicensed spectrum.
