Abstract: Certain aspects of the present disclosure provide techniques for enhanced physical uplink control channel (PUCCH) transmission. In some cases, a UE obtains payload bits to be conveyed in a physical uplink control channel (PUCCH) transmission via an interlace of resource blocks (RBs), determines a group of the RBs available to the UE, and transmits the payload bits using the determined group of RBs, wherein the transmitting involves modulating different RBs of the group by at least one of different payload bits or sequences.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor a first control channel in a first frequency band. The UE may determine that a bandwidth capability of the UE supports communicating on the first frequency band and at least a second frequency band. The UE may perform a channel measurement procedure on the first frequency band and the second frequency band concurrently. The UE may transmit a channel feedback message including information associated with the channel measurement procedure.

Abstract: Disclosed embodiments facilitate UE location determination in systems with dense PRS configurations, reduced PRS periodicity, frequency hopping, and involving UE inter-frequency measurements. The techniques may be applied to Bandwidth reduced-Low complexity (BL) UEs, or enhanced Machine Type Communication (eMTC) UEs or Further enhanced MTC (FeMTC) UEs and/or in LTE-M systems. A method on a UE may comprise: receiving a Reference Signal Time Difference (RSTD) measurement request; transmitting, in response to the RSTD measurement request, a dedicated gap request comprising a requested configuration of dedicated gaps; and receiving, in response to the dedicated gap request, a message comprising a dedicated gap configuration. The dedicated gap request may comprise a request for dedicated measurement gaps and the message may comprise a dedicated measurement gap configuration. In some embodiments, the dedicated gap request may comprise a request for dedicated autonomous gaps and the message may comprise a dedicated autonomous gap configuration.

Abstract: A user equipment (UE) may employ an extended cyclic prefix, a postfix, or both for sounding reference signal (SRS) transmissions, such that gaps between SRS transmissions are long enough for UE antenna switching operations, but shorter in duration than any maximum channel vacancy time durations set by a wireless communications system. Further, UEs may transmit SRSs to base stations in accordance with an SRS configuration. For example, a base station may provide SRS configuration information to a UE that indicates, for example, information related to SRS scheduling, subband information, a cyclic prefix length, a cyclic postfix length, listen-before-talk (LBT) type information, an SRS trigger, an SRS cancellation procedure, or any combinations thereof. Based on such SRS configuration information, a UE may perform partial subband SRS techniques, subband selection techniques, SRS bandwidth adaptation techniques, LBT type configuration techniques, etc.

Abstract: Methods, systems, and devices for wireless communications are described to enable a user equipment (UE) to identify one or more missed downlink control messages. The UE may use indicators received with downlink control messages to order the downlink control messages and determine if a message is missing. Indicators in different downlink control messages may be transmitted using different numbers of bits, and the UE may use methods to compare the indicators with different bit sizes. The UE may compare all the indicators using the smallest indicator bit size or may compare indicators in sequential pairs, using a shared bit size for indicators having a same bit size and using a smallest bit size for indicators having different bit sizes. After comparing indicators and determining if one or more messages are missing, the UE may notify the base station of any missing downlink control messages using a feedback message.

Abstract: This disclosure provides systems, methods and apparatus, and computer programs encoded on computer storage media, for managing paging monitoring by a wireless device. In one aspect, the wireless device may receive a serving cell signal from a cell. The wireless device may determine a delay time based on the serving cell signal. The wireless device may monitor for the paging signal during the determined delay time. The wireless device may stop the monitoring for the paging signal upon or after expiration of the determined delay time. In some aspects, the wireless device may receive an indication of multiple paging signal monitoring occasions from the cell, which may include an indication of a number of synchronization signal blocks (SSBs) to be transmitted from the cell and a number of physical downlink control channel (PDCCH) monitoring occasions per SSB in a paging occasion.

Abstract: Wireless communications systems and methods related to improving multiplexing capability in a frequency spectrum are provided. A first wireless communication device obtains a configuration for communicating a communication signal in a frequency spectrum. The configuration is based on at least a number of wireless communication devices scheduled to communicate in a time period. The configuration indicates resources in the frequency spectrum over the time period and a frequency distribution mode of the resources. The first wireless communication device communicates, with a second wireless communication device, the communication signal in the frequency spectrum during the time period based on the configuration.
