Abstract: Aspects of the present disclosure provide for the transmission of a cell identifier of a serving cell to a user equipment (UE). A Physical Cell Identification Channel (PCICH) is defined for carrying the cell identifier of the serving cell within an uplink-based mobility framework. In some examples, the PCICH may be transmitted in response to a trigger event that requires the user equipment to have knowledge of the cell identifier. For example, the UE may require the cell identifier to demodulate signals received from the serving cell and facilitate transmission and/or reception of user data traffic with the serving cell.

Abstract: Certain aspects of the present disclosure provide techniques for supporting UL-based mobility without DL zone signals. A DL zone signal may refer to a zone synchronization signal or a zone measurement reference signal. As described herein, a UE may perform certain operations upon power-up or RLF recovery, perform operations in each DRx cycle, and/or perform inter-zone handovers without relying on DL zone signals. Thus, aspects create a more user-centric environment and reduce and/or avoid transmission DL zone signals.

Abstract: Aspects of the disclosure relate to determination of bandwidth, frequencies, or a set one or more of subbands that carries a downlink control channel. In some examples, a set of one or more subbands that carries a downlink control channel may be determined based on a function of a predetermined reference resource location. The predetermined reference resource location may be a set of one or more subbands that carries one or more synchronization signals and a broadcast channel. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects of the present disclosure describe receiving synchronization signals in wireless communications. A block of synchronization signals can be received from a base station in a first time interval. A beam identifier and a redundancy version associated with the block of synchronization signals can be determined. A broadcast channel can be received based at least in part on a timing associated with the beam identifier. The broadcast channel can be descrambled based at least in part on a scrambling code associated with the redundancy version.

Abstract: Aspects of the present disclosure provide a scalable SIB bitmap structure. As described herein, a UE may generate and transmit, to an access network, a dual-layer system information block (SIB) request, wherein a first layer indicates a SIB category and a second layer indicates one or more groups within the SIB category. A base station in an access network may receive, from a UE, the dual-layer SIB request. The scalable, efficient bitmap structure may be shared by the UE and access network, thereby enabling SIB-on-Demand requests by the UE and responses to SIB-on-Demand requests by the access network.

Abstract: Aspects of the present disclosure provide apparatus and techniques that may be applied in systems for improving reliability of cell selection to ensure that a UE is capable of transmitting on the uplink in addition to receiving on the downlink upon mobility An exemplary method, performed by a user equipment (UE), generally includes receiving reference signals from one or more transmission reception points (TRPs) in a wireless communications network, pre-selecting, based on the received reference signals, a first TRP, of the one or more TRPs, from which to receive wireless service, transmitting an uplink (UL) signal to the first TRP, receiving, from the first TRP, feedback comprising information about the UL signal, and determining, based at least in part on the feedback, to select the first TRP from which to receive the wireless service.

Abstract: Systems and methods herein create unified synchronization to support various network deployments in which multiple UE states (e.g., idle, connected, etc) and multiple synchronization signal periodicities (5 ms, 20 ms, etc.) and standalone/non-standalone networks may exist. Unified synchronization may be achieved at least by designating transmit frames as being even or odd. With such a designation, when a network transmits synchronization signals (SS) comprising the most significant bits (MSB)s of a frame's system frame number (SFN), a UE of any state may receive the SS according to any periodicity and blind decode the SFN's least significant bits (LSBs) with less complexity as compared to traditional systems and methods due at least to the even or odd frame designations.

Abstract: Methods, systems, and devices for wireless communication are described that provide for synchronization signal (SS) blocks in which synchronization signals and broadcast channel transmissions may be transmitted. Broadcast channel transmissions may be demodulated using SS transmissions, reference signal transmissions, or combinations thereof. Broadcast channel transmissions may be transmitted in a subset of SS block time resources, and synchronization signals may be transmitted in another subset of SS block time resources. Reference signals may be transmitted using tones within the broadcast channel time resources, and may be transmitted at a higher density for portions of the broadcast channel transmission bandwidth that are outside of the SS transmission bandwidth. Waveforms for reference signal transmissions, and information provided by reference signal transmissions may be provided.

Abstract: Aspects of the present disclosure describe discovering physical cell identifiers in wireless communications. It can be determined to discover a physical cell identifier of one or more cells in a zone based at least in part on detecting a condition. A cell-specific signal can be received from at least one cell of the one or more cells in the zone. The cell-specific signal can be associated with one of a plurality of cell-specific signal hypotheses. The physical cell identifier of the at least one cell can be determined as one of a plurality of physical cell identifiers that corresponds to the one of the plurality of cell-specific signal hypotheses.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes receiving an indication of at least one receive capability of a network access device; transmitting a first message of a random access channel (RACH) procedure; receiving a random access response (RAR) message in response to transmitting the first message; and interpreting the RAR message according to a format based at least in part on the received indication. A method for wireless communication at a network access device includes transmitting an indication of at least one receive capability of the network access device; receiving, from a UE, a first message of a RACH procedure; and transmitting a RAR message to the UE in response to receiving the first message. The RAR message has a format based at least in part on the at least one receive capability of the network access device.
