Abstract: Various aspects described herein relate to techniques for synchronization channel design and signaling in wireless communications systems (e.g., a 5th Generation (5G) New Radio (NR) system). In an aspect, a method includes identifying a frequency band supported by a user equipment (UE), identifying one or more frequency locations based on the identified frequency band, and the one or more frequency locations are a subset of synchronization raster points used for synchronization signal transmission. The method further includes searching for at least one synchronization signal based on the one or more identified frequency locations.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a carrier aggregation (CA) configuration for communications on a set of cells. The UE may determine that signals transmitted on the set of cells may be spatially quasi co-located based on the CA configuration and a predetermined relationship rule. For example, the UE may determine that the signals are spatially co-located based on receiving multiple synchronization signal blocks (SSBs) that have a same SSB index, receiving a common SSB, assuming that an SSB and reference signals sourced by the SSB are spatially quasi co-located, receiving a signal from a particular cell of the set of cells, or receiving a common spatial QCL relationship during a configured period of time. Once the spatial QCL relationship is determined, the UE may receive the signals transmitted on the set of cells based on the spatial QCL relationship.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to reference signal (RS) designs that allow for tracking loop updates and paging of UEs using various RSs. One example method includes identifying reference signal (RS) monitoring occasions for a user equipment (UE) in an idle or inactive mode; and transmitting, to the UE, reference signals in the identified RS monitoring occasions, the RS monitoring occasions being associated with RS for tracking purposes and RS for an indication the UE is to wake up to process additional signaling.

Abstract: Systems and methods configured to provide size matching of downlink control information (DCI) formats to restrict a number of DCI format sizes for a set of DCI formats for concurrent use are described. In accordance with embodiments of the present disclosure, size matching at least two DCI formats of a set of DCI formats to restrict a number of DCI format sizes for the set of DCI formats for concurrent use is implemented. Restrictions with respect to the number of DCI format sizes for the set of DCI formats may correspond both to a first number of DCI sizes parameter based on a total number of DCI format sizes per wireless communication slot, and to a second number of DCI sizes parameter based on a total number of DCI format sizes for DCI formats used to carry DCI payload encoded using an identifier per wireless communication slot.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to random access channel (RACH) procedures in deployments where a RACH transmission may be sent on different UL carriers. An exemplary method performed by a base station includes receiving a random access (RA) preamble on a first component carrier (CC) of a plurality of CCs including at least one uplink (UL) CC and at least one supplemental uplink (SUL) CC and transmitting a response to the RA preamble, wherein the response indicates the first CC.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first hybrid automatic repeat request acknowledgement (HARQ-ACK) payload for a first component carrier (CC) set based at least in part on a first downlink assignment index (DAI). The UE may determine a second HARQ-ACK payload for a second CC set based at least in part on a second DAI. The UE may transmit the first HARQ-ACK payload for the first CC set and the second HARQ-ACK payload for the second CC set. Numerous other aspects are provided.

Abstract: Techniques are described herein for signaling procedures that use a hierarchical mobility, which may be applied when a user equipment (UE) is operating in a radio resource control (RRC) inactive state or the RRC idle state. A wireless communication system may be configured with a plurality of areas in which one or more networks are established for communicating certain types of signals. Examples of the areas associated with networks may include a tracking area (TA), a radio access network area code (RAN-AC), a radio access network based notification area (RNA). A synchronization signal or a paging signal may be transmitted using a first set of communication resources in a first area, while the synchronization signal or the paging signal may be transmitted using a second set of communication resources in a second area different than the first set of communication resources.

Abstract: Methods, systems, and devices for wireless communications are described that provide for allocation of control channel candidates for multiple component carriers (CCs) in carrier aggregation (CA) communications. A CA limit may correspond to a total number of configurable control channel candidates across multiple CCs. The control channel candidates may include blind decoding (BD) candidates or control channel element (CCE) candidates for channel estimation. A per-CC limit of control channel candidates may correspond to a number of configurable control channel candidates for each CC. An applied set of control channel candidates may be determined by allocating control channel candidates across the multiple CCs based on the CA limit and the per-CC limit. Such techniques may be used in cases where the CCs have a same numerology or mixed numerology, and may also be used for cross-carrier scheduling.

Abstract: Methods, systems, and devices for wireless communications are described. A network device such as a next generation (gNB) may identify control information for transmission on a downlink control channel e.g., a physical downlink control channel (PDCCH). The network device may identify a candidate set of decoding candidates to which the control information is able to be mapped. In some examples, each decoding candidate may include one or more control channel elements (CCEs). The network device may select, from the candidate set of decoding candidates, an actual set of decoding candidates to which the control information is to actually be mapped, and map the control information into the actual set of decoding candidates. Upon decoding the control information, the network device may transmit the control information within a search space including the actual set of decoding candidates to a user equipment (UE).

Abstract: Certain aspects of the present disclosure provide techniques for rate matching PDSCH around NZP CSI RS transmissions in multi-TRP scenarios. In some cases, a network entity may signal a rate matching behavior to a user equipment (UE) for processing a physical downlink shared channel (PDSCH) configured with a first quasi co-location association and transmitted from a first transmission reception point (TRP) that potentially collides with one or more types of non-zero power (NZP) reference signals (RS) configured with a second quasi co-location association and transmitted from a second TRP using one or more resource sets.
