摘要： 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.

摘要： In a user equipment (UE) of a wireless communication network, the UE configured to operate in half duplex frequency division duplexing (HD-FDD) mode in the network the UE configures for one or more conditions under which the UE will transmit under HD-FDD mode in uplink (UL) to the network and not receive in downlink (DL) from the network during a Random Access Channel (RACH) procedure. The UE determines whether the configured one or more conditions obtain for a particular RACH procedure. Upon determining that the configured one or more conditions obtain for the particular RACH procedure, the UE transmits under HD-FDD mode in UL during the particular RACH procedure in accordance with the configured one or more conditions.

摘要： Certain aspects of the present disclosure provide techniques for slot format configuration. A method that may be performed by a user equipment (UE) includes sending a message to a base station (BS) with UE capability information indicating one or more capabilities of the UE. The method includes receiving signaling from the BS indicating a semi-static slot format configuration based on the UE capability information, the slot format configuration including one or more slot format patterns and a cyclic shift (CS) associated with one or more slot format patterns. The method includes communicating with the BS based on the semi-static slot format configuration and the CS.

摘要： The aspects described herein are directed to measurement and reporting procedures of an apparatus (e.g., a low-tier user-equipment (UE) or a regular UE) when a bandwidth part (BWP) of the apparatus includes one or both of a first type of synchronization signal block (SSB) (e.g., a cell-defining (CD-SSB)) and second type of SSB (e.g., a non-cell-defining SSB (NCD-SSB)). The apparatus measures at least one of the first type of SSB that is periodically transmitted to a first group of UEs, a second type of SSB that is periodically transmitted within a time window to a second group of UEs, or both the first type of SSB and the second type of SSB for an operation based on a configuration of the operation, and performs the operation based on a measurement of at least one of the first type of SSB, the second type of SSB, or a combination thereof.

摘要： 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.
