Abstract: User Equipment (UE) receives, from a base station (BS), at least one resource block (RB). The RB includes at least one reference signal (RS) resource element (RE) of a first physical channel of the UE. The UE estimates a channel quality of a second physical channel of the UE as a function of the at least one RS RE. In some examples, the BS associates the transmission of a first physical channel reference signal (RS) and the transmission of a second physical channel RS. The BS then signals, BS to the UE, the association between the first physical channel reference signal and the second physical channel reference signal.

Abstract: Methods, systems, and devices for wireless communication are described. In some cases, due to blind decoding and channel estimation (CE) limits, one or more user equipment (UE) specific search sets may be pruned for blind decoding and/or CE purposes. For instance, after hashing a set of common decoding candidates to control channel elements (CCEs) within the control region, the UE specific search sets may be pruned so as to conform to the blind decode limitation, since a common search space has already occupied a portion of the total blind decode limit. Following pruning, the UE may hash the sets of UE-specific decoding candidates associated with the one or more UE specific search sets to CCEs within the control region. The UE may further prune UE specific search sets, based on CE limits, while reusing CE for overlapping hashed locations.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for a user equipment (UE) entering a dormant state with respect to a secondary cell group (SCG) of a node network (SN) having a primary serving cell (PSCell). In one aspect, the UE may maintain a parameter set for at least the PSCell while the UE is in the dormant state with respect to the SCG. For example, the UE may receive a parameter change message from either the SN or a master network (MN) and transmit a parameter change acknowledgment to either the SN or the MN. The parameter change message may be transmitted as one or both of a downlink control information (DCI) or media access control (MAC) control element (CE). The UE may transmit physical layer measurements to the SN based on the parameter set.

Abstract: A time-of-arrival (TOA) estimation method for multi-band orthogonal frequency division multiplexing (MB-OFDM) signals uses a simple equally-spaced channel model to recover the impulse response of the wireless channel, and locates the delay of the first channel path by minimizing the energy leakage from the first channel path. The TOA is estimated based on the delay. Such a method does not require channel information for TOA estimation at the receiver and does not require modification of the receiver structure. The method also avoids a sub-optimal solution known to occur in maximum likelihood (ML) estimation.
