Abstract: Methods, systems, and apparatuses for wireless communication are disclosed. In one aspect, a user equipment (UE) determines to perform a synchronization procedure and receives at least one synchronization signal. The UE may generate a detection metric based at least in part on the at least one synchronization signal and compare the detection metric or detection metrics accumulated since determining to perform the synchronization procedure with a detection threshold. The detection threshold may be associated with the at least one synchronization signal utilized to determine whether the synchronization procedure can be terminated prior to receiving a predetermined number of synchronization signals. The UE may continue or terminate the synchronization procedure based at least in part on a result of the comparison.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communication system may support techniques for correlation-based hardware sequences for layered decoding. In some cases, a user equipment (UE) may partition layers of a submatrix associated with a parity check decoding procedure into a first set of layers and a second set of layers. The UE may sort each set of layers into a respective set of layer orders (e.g., a first set of layer orders and a second set of layer orders) based on an associated set of correlation values. The UE may combine the first set of layer orders and the second set of layer orders to obtain a set of combined layer orders and may select a decoding schedule from a set of decoding schedules used for decoding each of the combined layer orders based on respective schedule lengths for the set of decoding schedules.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE), such as a UE with reduced capabilities, may switch from a first bandwidth part (BWP) to a second BWP to receive system information for a carrier that includes the first and second BWPs. The UE may switch to the second BWP to receive system information based on a trigger (e.g., control signaling or an expiration of a timer) and then switch back to the first BWP without additional signaling to continue operation. In some examples, the UE may receive additional signaling (e.g., data, control signaling, reference signals) in the second BWP. In some examples, a BWP switching duration may include additional time to process the system information received in the second BWP, for example if the system information includes instructions to switch to a third BWP (e.g., rather than returning to the first BWP).

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support marking symbols and validation of non-cell-defining-synchronization signal block (NCD-SSB) and random access channel (RACH) occasions within 5G new radio (NR) networks. In a first aspect, a method of wireless communication includes the UE obtaining an uplink-downlink configuration for one or more slots, an NCD-SSB configuration identifying NCD-SSB transmissions, and a bandwidth configuration identifying a bandwidth part (BWP) allocated to the UE and a configuration for cell-defining-synchronization signal block (CD-SSB) transmissions. The UE can mark a configured flexible symbol as a downlink symbol in response to either an NCD-SSB symbol or a CD-SSB symbol overlapping with the flexible symbol. Other aspects and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for power savings for reduced capability devices. A method that may be performed by a user equipment (UE) includes receiving a shared bandwidth part (BWP) configuration and a group common BWP configuration. The group common BWP configuration indicates a group common BWP shared by a group of UEs, including the UE, having one or more common capabilities or a common UE type. The method includes communicating using the group common BWP based on the group common BWP configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may signal, to a base station, a capability of the UE relating to carrier aggregation for a particular category or class of the UE, such as for narrowband Internet of Things (NB-IoT) UEs. The UE may receive, from the base station, a configuration for carrier aggregation for the particular category or class of the UE based at least in part on the capability of the UE relating to carrier aggregation for the particular category or class of the UE. The UE may communicate with the base station using carrier aggregation based at least in part on the configuration for carrier aggregation for the particular category or class of the UE. Numerous other aspects are provided.

Abstract: Channel estimation performance depends on the amount of averaging performed by a channel impulse response coherent filter. For half-duplex UEs, which use a single phase locked loop (PLL) for both downlink transmissions and uplink transmissions, averaging may not be performed across downlink subframes before and after uplink subframes if the PLL's phase changes and locks to a random initial value when switching transmission directions. Techniques disclosed herein facilitate estimating the PLL's random initial phase and enable correcting the phase of symbols accordingly. By correcting the phase of the symbols, it is possible to average across symbols before and after a frequency re-tune and/or a transmission direction switch based on the phase correction. This may serve to improve the accuracy of channel estimation. Further techniques disclosed herein may improve the accuracy of Doppler estimations by enabling the inclusion of symbols before and after a frequency re-tuning when performing the Doppler estimation.

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. A frame, scheduling instance, scheduling period etc. may include a set of downlink subframes and a set of uplink subframes. At least one control message transmitted in a downlink subframe may schedule a set of data messages in the downlink subframes of the frame. The downlink subframe may also include data messages scheduled by a control message of a previous frame. Further, feedback timings for data messages of the frame may be determined based on the corresponding control messages (e.g., from the current frame and the previous frame). Feedback responses corresponding to the data messages may be transmitted in a bundled manner in the set of uplink subframes. Using this cross-frame scheduling technique, the resources of a frame may be efficiently utilized.
