Abstract: In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for determining, by a user equipment (UE), an evaluation time period based on a number of a plurality of reference signals that are quasi-co-located (QCL) within one or more measurement windows; measuring, by the UE, a signal quality value of one or more of reference signals within the evaluation time period; and determining, by the UE, whether the signal quality value of one or more of reference signals within the evaluation time period crosses an evaluation threshold.

Abstract: A base station maps code blocks of a transport block of a transport block size (TBS) for a channel using tone-level interleaving or resource element (RE)-level interleaving. Then, the base station can transmit the code blocks of the transport block of the TBS for the channel. A UE may receive the channel from the base station and de-interleave the received tones of the channel in a frequency domain to obtain the code blocks of the transport block having the TBS for the channel.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a User Equipment (UE). The UE receives a second random access message from the base station after transmitting a first random access message. The second random access message comprises a random access response (RAR) that indicates a narrowband to be used for receiving a fourth random access message. The apparatus determines whether to perform a measurement of the narrowband for the fourth random access message based on an amount of time between receiving the second random access message and transmitting a third random access message. The base station may determine whether the report comprises a measurement of the first narrowband or the second narrowband based on an amount of time between the second random access message and the third random access message or based on an indication in the third random access message.

Abstract: Disclosed are techniques related to wireless communications. In an aspect, a network entity determines whether a source reference signal transmitted from a first transmission-reception point (TRP) is a quasi-collocation (QCL) source of a target reference signal transmitted from a second TRP based, at least in part, on a first bandwidth (BW) portion occupied by the source reference signal and a second BW portion occupied by the target reference signal, the first BW portion having a first start frequency and a first BW size and the second BW portion having a second start frequency and a second BW size, and configures a user equipment (UE) with the source reference signal as the QCL source of the target reference signal when it is so determined.

Abstract: A measurement period in which a User Equipment (UE) can be configured to take Positioning Reference Signal (PRS) measurements may include receiving PRS resources of a plurality of Positioning Frequency Layers (PFLs). To do so, the UE may tune (RF) circuitry of the UE from an active Bandwidth Part (BWP) to a frequency band of the at least one PFL, receive a plurality of PRS resources of a plurality of PFLs from one or more network nodes, and subsequent to receiving the plurality of PRS resources, re-tune the RF circuitry of the UE to the active BWP. The UE can then determine PRS measurements based on the plurality of PRS resources.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a network node performs one or more positioning measurements of one or more types of positioning measurements of one or more reference signals, and reports, to a positioning entity, the one or more positioning measurements and one or more measurement quality values representing a measurement quality of the one or more positioning measurements, the one or more measurement quality values based on measurement quality reporting parameters, wherein the measurement quality reporting parameters comprise a minimum error value, a maximum error value, a number of bits used for the one or more measurement quality values, a scaling function or an identifier of the scaling function, or any combination thereof.

Abstract: Aspects of the disclosure relate to a wireless user equipment (UE) establishing and utilizing a reference timing for a carrier or cell with multiple transmission and reception points (TRPs). A UE may receive a downlink signal on each of a plurality of component carriers (CCs), and determine respective timing events (e.g., slot boundaries, subframe boundaries, etc.) corresponding to each of the plurality of CCs. The UE may then determine a reference time for a first CC of the plurality of CCs. This reference time corresponds to a function of two or more timing events corresponding to different TRPs utilizing the first CC. The UE then determines a relative timing difference between the plurality of CCs based on this determined reference time. Other aspects, embodiments, and features are also claimed and described, including determining and utilizing a reference time on an uplink CC.
