Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may use enhanced techniques for determining whether a transmission is scheduled to include new data when a mode for reporting acknowledgment feedback is disabled for one or more hybrid automatic repeat request (HARQ) processes used by the receiving device. An enhanced technique may include increasing a quantity of bits used to convey an indication of whether a scheduled data transmission includes new data. An enhanced technique may include monitoring a duration between transmissions scheduled by different control messages based on a timing parameter that indicates a maximum time between transmissions of a data set and corresponding transmission including the data set.

Abstract: Methods, systems, and devices for wireless communications are described. These wireless communications may include channel estimation procedures between communicating devices such as a base station and user equipment (UE). For example, the UE may receive, from the base station, a resource grant triggering a given reference signal configuration. Based at least in part on the type of reference signal configuration, the UE (e.g., and the base station) may determine a timing offset relative to the resource grant. The UE may transmit (and the base station may receive) the reference signal based at least in part on the timing offset. In some cases, the reference signal may be transmitted in a transmission opportunity of a set of transmission opportunities, where the set of transmission opportunities is determined based at least in part on the reference signal configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first synchronization signal for synchronizing with a cell, the first synchronization signal transmitted at a first periodicity by a base station serving the cell. The UE may then receive, subsequent to the synchronizing, a second synchronization signal for resynchronizing with the cell. In some cases, the second synchronization signal may be transmitted by the base station according to a second periodicity that is different from the first periodicity. In some cases, the second synchronization signal may include a plurality of repetitions of a first sequence that is based at least in part on a cell identifier of the cell. The UE may communicate over the cell with the base station based at least in part on the resynchronizing.

Abstract: Methods, systems, and devices for wireless communications are described to enable a base station to configure additional reference signals, which may be referred to as configured reference signals, to include in a transmission to a user equipment (UE). The UE may transmit a report to the base station, indicating a UE capability for supporting configured reference signals, and the base station may configure a pattern for the configured reference signals. The base station may transmit an indication of the pattern to the UE, where the indication may include one or more characteristics associated with the configured reference signals. The base station may transmit the configured reference signals to the UE according to the pattern, along with one or more baseline reference signals, within an associated transmission. The UE may use the configured reference signals and the baseline reference signals to receive a transmission from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. that support preconfigured uplink resources (PUR) in wireless communications. A base station may communicate that support for PUR is available, and may allocate PUR resources to a user equipment (UE) based on requests from the UE. The UE may receive an indication that the base station supports PUR, such as via a system information block (SIB), determine to request PUR, and transmit a PUR request message to the base station. A PUR response from the base station may indicate configuration, or reconfiguration of PUR allocation for the UE that may be used for uplink transmissions, or release of the PUR allocation.

Abstract: Methods, systems, and devices for wireless communications are described that provide for multiple-input multiple-output (MIMO) transmissions of control information using downlink control channel resources, such as physical downlink control channel (PDCCH) resources. The MIMO transmissions may provide control channel transmissions to multiple UEs using the same time-frequency resources. A base station may use a subset of control channel monitoring entities for MIMO control channel transmissions, and another subset of control channel monitoring candidates for non-MIMO control channel transmissions. Control channel monitoring entities for MIMO transmissions may be defined separately from non-MIMO or legacy control channel candidates.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, for a base station, a configuration message indicating a set of random access resources associated with monitoring by a relay node. The UE may transmit a random access message using the random access resources to the relay node and a timing advance associated with uplink data transmissions by the UE. The UE may then communicate with the base station via the relay node based on the random access message. In some examples, a UE may monitor for a relay reference signal from a relay node. The UE may determine a signal strength and a timing of the relay reference signal. The UE may determine whether an RSRP satisfies a threshold receive power, and may determine whether the timing of the relay reference signal is less than a timing threshold. The UE may transmit a downlink relay request to the base station to initiate relay communications.

Abstract: A base station may perform interleaving of parts of a plurality of transport blocks for a broadcast or multicast transmission across a plurality of time intervals. A size of a transport block of the plurality of transport blocks may be scaled by a scaling factor. The base station may transmit the interleaved parts in the plurality of time intervals.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a multicast service available for subscription by the UE or to which the UE is already subscribed. The UE may transmit a message, to a network node, that may include UE assistance information (UAI) indicating at least one of a UE capability to process multicast transmissions or a feedback scheme preference for reporting feedback for the multicast transmissions. The UAI may also include at least one of a multicast carrier preference, band or carrier measurement report, a multicast priority indication, or a measurement and reporting scheme preference for the multicast transmissions. The network node may receive the UAI and determine one or more parameters for multicast communications with the UE based on the UAI. The UE may receive the multicast transmissions from the network node in accordance with the UAI.
