Abstract: Aspects are provided which improve the effectiveness of conflict resolution between a scheduled uplink transmission and a carrier-switched sounding reference signal (SRS). A UE receives a physical downlink control channel (PDCCH) from a base station. The PDCCH schedules an uplink transmission on a first carrier. The UE determines whether to drop one of the uplink transmission or transmission of a SRS on a second carrier different than the first carrier based on a timing between a reception time of the PDCCH and a scheduled time for transmitting the SRS. By factoring the timing into determination, situations may be eliminated where the UE is unaware that an uplink transmission will be scheduled at the time of the carrier-switched SRS.

Abstract: A configuration to enable a base station to adjust an error rate for paging and to advertise such error rate to UEs, in order to optimize or reduce network paging resources. The apparatus determines a target miss rate for paging on a downlink narrowband control channel. The apparatus transmits an indication of the target miss rate to one or more UEs. The indication is transmitted in system information or a dedicated downlink channel.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable mediums for indicating carrier pairings in supplemental uplink (SUL) communications. A method that may be performed by a user equipment (UE) generally includes determining carrier groupings for SUL communications supported by the UE, each carrier grouping comprising at least one component carrier (CC) carried in an SUL band and at least one CC carried in a non-supplemental uplink (NSUL) band and providing signaling indicating the carrier groupings for a combination of at least three CCs jointly carried in at least one SUL band and at least one NSUL band.

Abstract: Methods, systems, and devices for wireless communications are described. In some non-terrestrial networks, the movement of satellites may result in the movement of cell coverage. A user equipment (UE) may experience changing cell coverage due to the movement of cell coverage, even if the UE is stationary. A UE may be configured to determine a cell is serving two or more earth-fixed tracking areas, determine whether to monitor paging resources of a first earth-fixed tracking area or a second earth-fixed tracking area, and monitor the selected paging resources. In some aspects, the UE may determine that a cell serves two or more earth-fixed tracking areas based on a received control message including multiple tracking area indicators. In some aspects, the UE may determine which paging resources to monitor based on a geographic position of the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information (DCI) message associated with scheduling uplink transmissions from the UE on a set of component carriers (CCs). The DCI message may indicate that a first uplink channel on a first CC of the set of CCs at least partially overlaps in time with a second uplink channel on a second CC of the set of CCs. The UE may multiplex, based on the first uplink channel at least partially overlapping in time with the second uplink channel, uplink control information (UCI) with an uplink data transmission on the first CC or the second CC. The UE may transmit the UCI and the uplink data transmission multiplexed on the first CC or the second CC based at least in part on the DCI message.

Abstract: Certain aspects of the present disclosure provide techniques for adjusting PDCCH processing or PDCCH DMRS processing, such as to avoid cell-specific reference signal (CRS) of long-term-revolution (LTE). For example, a UE may adjust at least one of physical downlink control channel (PDCCH) processing or PDCCH demodulation reference signal (DMRS) processing of a first radio access technology (RAT), such as LTE, based on whether one or more resource elements (REs) of a PDCCH candidate in a PDCCH monitoring occasion of the first RAT is configured as overlapping with one or more REs of a CRS of a second RAT, such as 5G new radio (NR). The UE then monitors PDCCH candidate in the PDCCH monitoring occasion based on the adjusting.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for pilot design for Narrow-Band Internet of Things (NB-IoT). In certain aspects, the method generally includes determining at least one binary code sequence to use as a demodulation reference signal (DMRS) for a channel transmitted across one or more subframes using one or more tones within a resource block (RB) allocated to the UE for narrowband communication, and transmitting the channel including the DMRS using the one or more tones and the determined binary code sequence. In certain aspects, the binary code sequence may be determined based on a binary random sequence, such as pseudo noise (PN) or Gold sequence.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information indicating an offset of an energy level of a resynchronization signal (RSS) of a neighbor cell relative to a cell-specific reference signal (CRS) of the neighbor cell; and perform a measurement based at least in part on the offset. Numerous other aspects are provided.

Abstract: An apparatus for wireless communications includes a processor, and a memory coupled with the processor and storing instructions operable, when executed by the processor, to cause the apparatus to output a pre-configured uplink resource (PUR) configuration information comprising a least significant bit (LSB) associated with a hyper system frame number (H-SFN). Execution of the instructions further cause the apparatus to obtain, from a user equipment (UE) at a PUR start time, a first message on a PUR associated with the PUR configuration information, the PUR start time associated with the H-SFN corresponding to the LSB.

Abstract: A central unit (CU) transmits synchronization timing information for a multicast broadcast service (MBS) single frequency network (SFN) data transmission in a synchronous manner to multiple distributed units (DUs). The CU transmits the MBS SFN data transmission to the multiple DUs for synchronous transmission to one or more user equipments (UEs). A DU receives synchronization timing information for a MBS SFN data transmission in a synchronous manner with at least one additional DU. The DU transmits the MBS SFN data transmission with a timing based on the synchronization timing information.
