The aspects in- clude receiving a random access configuration at the UE includ- ing configuration for CFRA and CBRA. The UE will determine a first random access resource, wherein the first random access re- source maps to one or more beams from a target base station. The UE may initiate a random access request using the CFRA when the first random access resource is a contention-free resource, and initiate the random access request using the CBRA when the first random access resource is a contention-based resource.

    Abstract: Methods, systems, and devices for wireless communications are described for configuration aspects of a tracking reference signal in New Radio. A base station may select a first burst duration and a second burst duration for a tracking reference signal (TRS) burst, the first burst duration being different from the second burst duration, and may transmit configuration information indicating the first burst duration and the second burst duration to a user equipment (UE). The base station may transmit a first TRS burst having the first burst duration and a second TRS burst having the second burst duration. The UE may detect the first TRS burst having the first burst duration and the second TRS burst having the second burst duration based at least in part on the configuration information, and perform resource tracking based at least in part on the detected first TRS burst and the second TRS burst.

    Abstract: Various aspects described herein relate to techniques for signaling and using one or more virtual cell identifications (V-cell IDs) for single frequency network (SFN)-type of transmissions in wireless communications systems. A method, a computer-readable medium, and an apparatus are provided. In an aspect, the method may include performing, by a user equipment (UE), a cell search to obtain a cell ID, and decoding, by the UE, a message based on the cell ID, wherein the message includes a master information block (MIB). The method may further include identifying, by the UE, a virtual cell ID used for SFN-type transmissions based on information decoded from the message. The techniques described herein may apply to different communications technologies, including 5th Generation (5G) New Radio (NR) communications technology.

    Abstract: Aspects provide a way for RS in different sub-bands within the same OFDM symbol to have different RS placement designs, e.g., different dependence/independence on cell ID. A base station apparatus transmits a first RS in a first resource set using a first RS placement, wherein the first resource set comprises a first subband of an OFDM symbol. The apparatus also transmits a second RS in a second resource set using a second RS placement, wherein the second resource set comprises a second subband of the OFDM symbol. A UE apparatus identifies a first resource set comprising a first subband in a plurality of subbands of an OFDM symbol transmitted by base station, determines whether a RS tone location utilized with the first subband is dependent upon an identifier of the base station, and receives the RS based on a result of the determining.
