摘要： Aspects are provided to support payloads for msgA transmission in a two-step random access (RACH) procedure by providing a one-to-many mapping arrangement between preambles and physical uplink shared channel (PUSCH) resource units (PRUs). A preamble is determined by the UE which is mapped to one or more groups of PRUs to support piggybacking of uplink control information (UCI), frequency hopping on PUSCH, and multiple-slot repetition for msgA transmissions. By piggybacking UCI to a payload in msgA, flexibility may be provided in the selection of MCS and waveform as well as resource allocation for demodulation reference signals (DMRS) and PUSCH in PRUs. Moreover, by allowing a payload to hop to different frequencies on PUSCH during the transmission of msgA, a gain in frequency diversity and interference averaging may be provided, and by enabling a payload to repeat across multiple slots in msgA transmission, coverage enhancement and/or reliability may be increased.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a resource configuration for a random access (RA) procedure. The resource configuration may identify multiple sets of transmission resources corresponding to multiple radio resource control (RRC) states. The UE may identify an RRC state and may determine a set of transmission resources and/or a transport format based on the indication of the resource configuration, the identified RRC state, and/or a UE identifier (UE ID). The UE may transmit a first RA procedure message (e.g., a msgA) using the determined transmission resources and/or transport format. The base station may receive the message and may identify the RRC state of the UE based on the first message and transmitted indication of the resource configuration. The base station may transmit a second RA procedure message (e.g., a msgB), which the UE may receive.

摘要： Wireless communications systems and methods related to joint-carrier scheduling using a single downlink control information (DCI) signal. The user equipment (UE) receives from a base station (BS) of a first serving cell, a downlink control information (DCI) that indicates a joint-carrier scheduling scheme. Using the joint-carrier scheduling scheme in the DCI, the UE schedules first data for communication on a first shared channel associated with the first serving cell and second data for communication on a second shared channel associated with a second serving cell.

摘要： Certain aspects of the present disclosure provide techniques for uplink scheduling for communication on an uplink from a user equipment (UE) to a base station (BS). The uplink scheduling is based on uplink transmission (UL Tx) switching time and/or uplink data preparation time of the UE. The uplink data preparation time is calculated based on the UL Tx switching time. For example, a UE can report to a BS at least one of an indication of a UL Tx switching time and an uplink data preparation time of the UE. In return, the UE can receive an indication of uplink scheduling from the BS, which the UE can use to communicate with the BS.

摘要： Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may In support multiple component carriers that may be used to transmit uplink transmissions. One carrier may be used at a time such that the may switch between the carriers based on an uplink transmission schedule. In some cases, switching may be limited by a consecutive uplink switching rule or UE capability. In some cases, the gap between two consecutive uplink carrier switching operations may be limited to a resource (e.g., slot, symbol), such that the UE may expect to perform at most one switching operation per resource. In some implementations, the gap between two consecutive uplink carrier switching operations may be limited to a duration (e. g., 14 symbols, 4 symbols), such that the UE may expect to perform at most one switching operation per a duration less than or equal to a threshold.

摘要： Increased symbol length of uplink pilot time slots (UpPTS) in special subframes is disclosed in which a configuration of a first special subframe may be independent from configuration of a second special subframe in the same frame, such that the first UpPTS of the first special subframe is longer than the second UpPTS of the second special subframe. The second UpPTS of the second special subframe may also be longer than legacy UpPTS length in select configurations. A serving base station may select the special subframe configurations in order to balance sounding reference signal (SRS) capacity for compatible user equipments (UEs) and downlink throughput for legacy UEs. The selected special subframe configurations may be transmitted by the serving base stations. In additional aspects, compatible UEs may be configured with at least two separate SRS power control parameters for use in the additional and legacy UpPTS symbols.

摘要： Certain aspects of the present disclosure provide techniques for signaling quasi-coloration (QCL) information for demodulation reference signals (DM-RS) associated with multiple transmission-reception points (multi-TRP). An example method generally includes generating quasi-colocation (QCL) information indicating a first QCL assumption for a first group of demodulation reference signal (DM-RS) ports and a second QCL assumption for a second group of DM-RS ports; and transmitting the QCL information to at least one user equipment (UE) for use in processing one or more transmission associated with at least one of the first group of DM-RS ports and the second group of DM-RS ports.

摘要： Aspects of the present disclosure relate to techniques for non-codebook based UL transmission. In some cases, a UE may signal, to a network entity, capability information of the UE for non-codebook uplink transmissions. The UE may then receive, signaling, from the network entity, indicating a plurality of sounding reference signal (SRS) configurations based at least on the signaled capability information, wherein at least one configuration indicates at least one SRS resource and determine a plurality of precoding candidates, wherein each precoding candidate is associated with a configured SRS resource. The UE may then transmit the SRSs using the associated precoding candidates.
