Abstract: Systems and methods are provided for determining which part or operation of one or more Secondary Cell (SCell) activation process (es) to defer or restart when an attempt to simultaneously perform multiple operations of the one or more SCell activation processes would cause interference. For example, radio frequency (RF) tuning and/or automatic gain control (AGC) settling for an SCell activation may be deferred until after a Hybrid Automatic Repeat Request (HARQ) for the SCell activation is sent by a UE to the SCell. In another example, RF tuning and/or AGC settling corresponding to the activation of a first SCell may be deferred until after RF tuning and/or AGC settling corresponding to the activation of a second SCell is complete.

IPC: H04W74/00

Abstract: The implementations disclosed provide apparatus, systems, and methods for channel structure construction for a two-step random access channel (RACH) using a new radio (NR) user equipment (UE) wireless device. The wireless device includes one or more computer processors configured to generate a physical RACH (PRACH) preamble mapped to a physical uplink shared channel (PUSCH) resource unit. The PRACH preamble is associated with a preamble group indicating a configuration of the PUSCH. The preamble group has a size indicated by radio resource control (RRC) signaling performed by the wireless device. A message is encoded including the PRACH preamble and a payload carried by the PUSCH. The configuration of the PUSCH includes parameters for decoding the message. The wireless device couples communicatively to a base station using the PUSCH. The message is transmitted to the base station. The base station decodes the message based on the parameters of the PUSCH configuration.

Abstract: A method performed by a user equipment (UE) is described. The method includes establishing a connection to a network that includes discontinuous reception (DRX) cycles, each DRX cycle including a scheduled OnDuration and a wake up signal (WUS) opportunity corresponding to each of the scheduled OnDurations, when a WUS is received in the WUS opportunity for one of the scheduled OnDurations, configuring the UE to utilize an active mode of processing during the one of the scheduled OnDurations and when a WUS is not received in the WUS opportunity for one of the scheduled OnDurations, configuring the UE to utilize a sleep mode of inactivity during the one of the scheduled OnDurations.

IPC: H04W8/24

Abstract: A wireless communication device (UE) may provide information pertaining to one or more operating capabilities of the UE to LTE and 5G-NR networks. The UE may transmit information to an LTE base station directly, and to a 5G-NR base station directly, or indirectly via the LTE base station. The information may include preferred values corresponding to any number of different operating parameters associated with wireless communications or wireless communication capabilities of the UE in both LTE and 5G-NR networks, to inform and/or request the LTE and 5G-NR networks to make provisions based on the transmitted information for the wireless communications of the UE on those networks. The UE may thereby provide assistance information to LTE and 5G-NR networks in a multi-radio-access-technology dual-connectivity setting to request the respective networks to adjust certain operating capabilities of the UE in order to alleviate one or more operating issues that may be affecting the UE.

Abstract: This disclosure relates to providing synchronization signal block index signaling in a cellular communication system. A cellular base station may provide synchronization signals according to a periodic pattern, including transmitting one or more synchronization signal bursts each including one or more synchronization signal blocks. A wireless device may detect a synchronization signal block. The wireless device may determine a synchronization signal block index of the detected synchronization signal block. The wireless device may provide an indication of the synchronization signal block index of the detected synchronization signal block to the cellular base station.

Abstract: This disclosure relates to performing cellular communication using modular control channel formats for uplink control information. A wireless device may determine a slot structure for uplink communication. The slot structure may be selected from multiple possible slot structures. Uplink control information may be transmitted via one or more uplink control channel modules during a slot. A number of uplink control channel modules on which uplink control information is transmitted during the slot may be selected based at least in part on the slot structure for uplink control communication.

Abstract: A wireless communication device (UE) may receive control indicator information (CII) indicating whether one or more candidate physical control channels (PCCs) are available to the UE for decoding. The UE may perform respective blind decoding if the CII indicates that the one or more candidate PCCs are available, to decode a respective PCC intended for the UE. The UE may receive the CII in the same slot in which PCCs are transmitted, or it may receive the CII in another slot, which may be a narrowband slot. The UE may receive the PCCs in the same slot in which corresponding physical data channels (PDCs) are transmitted, or it may receive the PCCs in another slot, e.g. a slot immediately preceding the slot in which the corresponding PDCs are transmitted. By eliminating unnecessary blind decoding and receiving the CII over narrowband, power consumption of the UE may be greatly reduced.
