Abstract: Certain aspects of the present disclosure relate to methods and apparatus mapping virtual resource blocks (VRBs) to physical resource blocks (PRBs) and using the mapping in wireless communications, for example, in new radio (NR) technologies. An exemplary method includes determining a first interleaved mapping that maps a first interleaving unit of N consecutive first virtual resource blocks (VRBs) to N consecutive first physical resource blocks (PRBs), wherein each first PRB comprises a set of frequency resources during a period, transmitting a first grant allocating the first interleaving unit of first VRBs to a first user equipment (UE), and communicating with the first UE via the first PRBs mapped to the first VRBs of the first interleaving unit.

Abstract: Methods, systems, and devices for using a common physical downlink control channel (PDCCH) to indicate transmission beams to be used by a base station during a transmission opportunity or a periodicity to monitor search spaces are described. A user equipment (UE) may monitor a search space (in some cases, using a periodicity) for the common PDCCH to determine if transmission beams associated with the UE are to be used during the transmission opportunity. If so, the UE may wake-up during at least a portion of the transmission opportunity to receive additional information. If the common PDCCH indicates that no transmission beams associated with the UE are to be used during the transmission opportunity, the UE may enter or re-enter the sleep state. The UE may switch to a new periodicity for monitoring the search space based on the information transmitted within the common PDCCH.

Abstract: Methods, systems, and devices are described for wireless communications. A wireless communication device may switch between a distributed and a clustered transmission scheme for control information transmissions. In some cases, the base station may indicate to a UE that a clustered control information transmission scheme will be used and may also indicate a monitoring pattern informing the UE how to identify its own control information in a control information set. For instance, a base station may indicate to the UE that a preferred beam of the UE is correlated with a symbol position of the UE's control information in the control information set. In some cases, the base station may indicate to a UE that a distributed control information transmission scheme will be used.

Abstract: A combined symbol constellation may be selected from a uniform symbol constellation that is supported by a de-mapper to provide additional power split options while reducing modifications to the de-mapper. In some examples, a signal may be constructed according to a combined symbol constellation selected from a larger uniform symbol constellation based on a desired power-ratio. The signal may include a base-layer, used to communicate a first set of data, and an enhancement-layer, used to communicate a second set of data, in accordance with the selected combined symbol constellation. The signal may be received and de-mapped according to the combined symbol constellation at a de-mapper that supports a uniform symbol constellation that is larger than the combined symbol constellation.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may allocate resources for communication with a user equipment (UE). The resources may include one or more subframes, and each subframe may include one or more shortened transmission time intervals (sTTIs). Each sTTI may be assigned a transmission direction according to a time division duplex (TDD) pattern. Based on traffic needs and/or interference from other UEs and/or base stations, the base station may determine to modify the TDD pattern used for communication. Accordingly, a base station may transmit an indicator in a control message or control region of a TTI or sTTI, to indicate to users that a transmission direction of an sTTI in the TDD pattern is being changed. Subsequently, a user may communicate with the base station according to the reconfigured TDD pattern.

Abstract: Methods, systems, and devices for wireless communication are described. A network access device may select a search space configuration for transmission of group(s) of one or more control channel elements (CCEs) to convey a downlink control information (DCI) message. The search space configuration may include a cross-coreset configuration, such as a cross-control channel subband configuration, a cross-symbol configuration, and/or a cross-beam configuration. The network access device may transmit the DCI message according to the selected search space configuration. A user equipment (UE) may monitor, based on the search space configuration, the group(s) of one or more CCEs to detect DCI messages. The UE may detect a DCI message for it and decode the DCI message based on the monitoring. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A base station and a user equipment (UE) may communicate in a high reliability and low latency communications system (e.g., ultra-reliable low latency communications (URLLC)). The base station may signal a UE-specific scheduling request (SR) repetition configuration that the UE may utilize to transmit an instantaneous SR when a buffer status report (BSR) is triggered by a new data packet. The UE may repeatedly transmit the SR until a number of repetitions or a time period of repetitions is met or an uplink grant is received from the base station. The SR repetition configuration may include a number of parameters including a repetition setting, power settings, a resource allocation, and an acknowledgement/negative acknowledgment (ACK/NACK) procedure.

Abstract: The present disclosure describes various aspects of the implementation and design of Physical Downlink Control Channel (PDCCH) in 5G new radio (NR) applications. Aspects include methods, apparatuses, and computer-readable medium for one or more of multiple PDCCH search spaces, control resource block (CRB), irregular multiple slots or mini-slots grants, or fast control channel signaling for grant-free uplink (UL). For example, different scheduling entities can each have one or two search spaces defined (e.g., common and/or user equipment (UE)-centric search spaces). Also, CRBs can be used as units for PDCCH transmission instead of resource element groups/control channel elements (REGs/CCEs). In addition, irregularities in time domain, frequency domain, or both can be introduced in the granting of resource blocks (RBs) over multiple slots or mini-slots. Moreover, signaling can be used to indicate to a UE configured for grant-free UL the portion of the pool of resources available for grant-free UL.

Abstract: Certain aspects of the disclosure relate to techniques and apparatus for improving random access for SRS switching in a wireless network. Prior to transmitting a SRS, a UE may interrupt communication on a first carrier to switch from the first carrier to a second carrier to transmit a PRACH. To reduce interruption to the first carrier, the UE may use the beginning symbol(s) of a UpPTS on the second carrier to transmit the PRACH. In addition, to reduce interruption to the first carrier, the UE may monitor for another PDCCH order before transmitting another PRACH. Further, aspects of the present disclosure provide techniques and apparatus for jointly triggering SRS transmissions and performing power control for SRS transmissions. A BS may trigger SRS transmissions from multiple UEs, trigger SRS transmissions from multiple carriers from the same UE at the same time and/or perform power control separately for each carrier.

Abstract: Various aspects of the disclosure relate to power control for independent links. For example, power control at a device may be based on transmissions on multiple links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, power control for the first device may be based on power control commands received on multiple links. In some scenarios, a power control constraint may be met taking into account the transmission power on multiple links.
