Abstract: Certain aspects of the present disclosure relate to methods and apparatus for limiting UE capability information reported in a network. For example, a method of wireless communications by a first base station may include transmitting a first set of initial access signals in different directions, receiving a second set of one or more signals from a user equipment (UE) in response to the first set of initial access signals, and initiating transmission of, or conveying configuration of, a third set of reference signals with an indication of their corresponding directions, based on reception of the second set of signals.

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.

Abstract: Certain aspects of the present disclosure provide procedures for new radio (NR) cell measurement. According to certain aspects, a method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving one or more downlink signals from a cell, wherein the cell is of a first cell type that supports a first set of functions or a second cell type that supports a second set of functions, wherein the second set of functions is different than the first set of functions; determining a cell type of the cell based on the one or more downlink signals; and communicating with the cell based on the determination.

Abstract: A non-geosynchronous satellite system, where each satellite has an antenna (perhaps a multi-element antenna) to form a beam pattern comprising a set of beams in the footprint of the satellite, where in one implementation each beam is substantially elliptical in shape having a minor axis and a major axis, where the minor axes are substantially collinear and the major axes are substantially oriented east to west. For a satellite, power is reduced or turned off for a subset of the set of beams, wherein each beam in the subset is reduced at or below a corresponding power level such that when a beam is powered above its corresponding power level an equivalent power flux-density (EPFD) exceeds a limit at some point on the Earth's surface.

Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems may support beamformed transmissions between devices (e.g., to improve coverage range). The beamformed transmissions may depend on discovery and maintenance of receive and transmit beams over which a given device may communicate with another device. Various receive and transmit beams for a given device may be compared using reference signals. As the number of devices attempting to access a cell increases, the number of reference signals to be transmitted may scale proportionally. Large numbers of reference signals may flood time-frequency resources of the system and/or require excessive processing at a mobile device. Scrambling sequences for reference signals may be employed to improve efficiency of resource usage. In aspects, the scrambling sequences may be implicitly determined (e.g., based on resources over which the access request was transmitted). Such an implicit association may reduce the need for additional signaling.
