Abstract: A base station may configure a user equipment (UE) to perform sounding reference signal (SRS) transmissions using an SRS resource set. The SRS resource set may be configured for two or more functions, e.g., functions such as codebook-based SRS transmission, non-codebook-based SRS transmission, antenna port switching, beam management, etc. By enabling the use of such dual function (or multi-function) SRS resource sets, the average data rate associated with configuration transmissions to the UE may be reduced.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for Fifth Generation New Radio (5G NR) frequency range two (FR2) based communications beam management. The UE may configure, via communications with a base station, serving the UE, a group ID for PUCCH resources within a group of PUCCHs, e.g., for FR2 based communications. The UE may receive, from the base station, an update to one or more PUCCH resources within the group of PUCCHs via a medium access control (MAC) control element (CE) that may include one of a resource ID indicating an update to a PUCCH resource or the group ID to update the group of PUCCH resources. The UE may update, based on the MAC-CE, the one or more PUCCH resources within the group of PUCCHs.

Abstract: Apparatuses, systems, and methods for performing uplink transmissions during a dual active protocol stack handover. A wireless device may determine a propagation delay between the wireless device and each of a source cell and a target cell of a dual active protocol stack handover by the wireless device. The wireless device may provide an indication to the source cell of the propagation delay between the wireless device and the source cell, the propagation delay between the wireless device and the target cell, and a propagation delay difference handling capability of the wireless device. The cellular base station that provides the source cell may determine a time division multiplexing pattern for uplink communication for the wireless device during the dual active protocol stack handover based at least in part on the information provided by the wireless device.

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.

Abstract: In an example method, a user equipment (UE) device determines an offset length of time associated with transmitting or receiving data over a wireless network. The UE device transmits an indication of the offset length of time to the wireless network. The UE device transmits or receives, during a first time interval, a first portion of data to or from the wireless network though a first wireless link. The UE device transmits or receives, during a second time interval, a second portion of data to or from the wireless network though a second wireless link. An end of first time interval is offset from a beginning of the second time interval by the offset length of time.

Abstract: This disclosure relates to performing cellular communication using a control information monitoring framework. A wireless device may monitor a control channel for control information according to a first periodic pattern. According to the first periodic pattern, the wireless device may monitor the control channel in a specified slot during each period of the first periodic pattern. Each period of the first periodic pattern may include multiple slots. The wireless device may receive control information during a first slot. The first slot may be a specified slot according to the first periodic pattern. The control information received during the first slot may schedule a data communication. The wireless device may monitor the control channel for control information in at least one slot that is not specified according to the first periodic pattern based at least in part on receiving control information during a specified slot according to the first periodic pattern.

Abstract: Apparatuses, systems, and methods to dynamically indicate preference for self-contained slots and slot duration by a user equipment device (UE) in communication with a base station (e.g., a gNB) using a 5G NR radio access technology. A UE may determine to send an indication to a gNB indicating a preference for self-contained slots and slot duration for downlink and/or uplink communications utilizing one or more of the physical downlink control channel (PDCCH), the physical downlink shared channel (PDSCH), and/or acknowledgement messaging (ACK/NACK) for downlink communications, and utilizing one or more of the physical uplink control channel (PUCCH), the PDCCH, and/or the physical uplink shared channel (PUSCH) for uplink communications. The configuration of self-contained slots and slot duration for uplink and/or downlink may be based on one or more of average packet size, average packet rate, traffic type and UE processing capabilities.

Abstract: Apparatuses, systems, and methods for PDCCH enhancements for group-based paging indications. A user equipment device may be configured to receive, from a network, an indication of a paging occasion via a PG-RNTI and/or via at least 6 bits of a DCI. A value of the PG-RNTI may be associated with the paging occasion as well as a set of UEs, including the UE. The UE may be configured to monitor the paging occasion based on the value of the PG-RNTI and receive, during the paging occasion, a paging indication via at least six bits of a DCI, where each bit of the at least six bits may indicate a paging indication for a particular set of UEs and the particular set of UEs may be a subset of the set of UEs. The UE may also be configured to, in response to determining that the UE has a paging message, decode a corresponding PDSCH.

Abstract: Systems, apparatuses, and methods for coverage improvements in wireless communication devices. A wireless communication device may be configured to selectively receive one of a plurality of paging signals, or a portion thereof, based on measured or expected coverage quality of communications from a base station. In some scenarios, the wireless communication device may provide an indication to the base station of which paging signal the wireless communication device will attempt to receive, such that the base station may include paging information directed to that UE only in the indicated paging signal. In some scenarios, the base station may include paging information directed to that UE in a plurality of paging signals, each of the paging signals including a different number of repetitions of the paging information. In some scenarios, the UE may receive only a portion of a paging signal including a plurality of repetitions of the paging information.

Abstract: This disclosure relates to orthogonal frequency division multiple access (OFDMA) communication in wireless local area networks (WLANs). According to some embodiments, a downlink OFDMA frame may be transmitted. An uplink OFDMA frame including acknowledgements associated with the downlink OFDMA frame may be received. The uplink OFDMA frame may be processed, in some instances including determining which devices receiving the downlink OFDMA frame transmitted an acknowledgement associated with the downlink OFDMA frame in the uplink OFDMA frame.
