摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether an uplink communication for a first radio access technology (RAT) has been dynamically scheduled or semi-statically configured, wherein the UE is in a dual connectivity mode using the first RAT and a second RAT. The UE may identify an uplink subframe for transmission of the uplink communication based at least in part on whether the uplink communication has been dynamically scheduled or semi-statically configured, and based at least in part on a downlink-reference uplink-downlink configuration. The UE may transmit the uplink communication in the identified uplink subframe. Numerous other aspects are provided.

摘要： Various arrangements for expediting sensor reporting in a wireless hybrid time division multiple access (TDMA) shared-medium network are presented. A TDMA channel allocation process for the wireless hybrid TDMA shared-medium network may be performed such that each sensor device of a plurality of sensor devices is assigned a different timeslot. Within each timeslot of the plurality of timeslots, a grant-free transmission window may be reserved. Any sensor device may be permitted to transmit data during any grant-free transmission window. In response to the sensor device determining the sensor data is to be transmitted, the sensor device may transmit a message indicative of the sensor data during a grant-free transmission window of a timeslot assigned to a different sensor device.

摘要： Wireless communications systems and methods related to channel access contention management in a shared radio frequency band are provided. A first wireless communication device communicates, with a second wireless communication device, a grant for communicating a first communication signal, the grant indicating a listen-before-talk (LBT) configuration. The first wireless communication device communicates, with the second wireless communication device, a LBT configuration modification after communicating the grant. The first wireless communication device communicates, with the second wireless communication device, the first communication signal based on the LBT configuration modification.

摘要： A wireless communication method includes transmitting, from a base station (BS), multiple downlink (DL) signals. The wireless communication method further includes receiving, with a user equipment (UE), two or more DL signals of the multiple DL signals, and notifying, with the BS, the UE of a number of the two or more DL signals. The two or more DL signals are associated with a Physical Random Access Channel (PRACH) resource.

摘要： A wireless device may receive at least one message comprising configuration parameters of a plurality of cells being in a cross-carrier scheduling group comprising a first cell and a second cell. The first cell identified by a first cell identifier may employ a first number of bits. The configuration parameters may indicate that the second cell is a cross-carrier scheduling cell for the first cell. The configuration parameters may comprise the first cell identifier and a first cell indicator field. The first cell indicator field may employ a second number of bits. The wireless device may receive downlink control information via a control channel of the second cell for a packet transmitted via the first cell. The downlink control information may comprise the first cell indicator field identifying the first cell. The wireless device may receive the packet on the first cell via radio resources identified by the downlink control information.

The method includes receiving, from a network node, a handover command, the handover command comprising at least one suitability threshold. Measurements of each of a plurality of beams detected by the wireless device are performed. The measurements of the plurality of beams are compared to the at least one suitability threshold. A particular beam is selected based on the comparison, and a random access procedure is initiated.
