摘要： A method of operating a communications device in a wireless communications system that supports a random access procedure. The method comprises receiving, from an infrastructure equipment, a scheduling message comprising an indication of an allocation of radio resources to be used for a random access procedure message, selecting a transport block size (TBS) from a plurality of permitted TBS values for the transmission of the random access procedure message, and determining whether the selected TBS is lower than a maximum TBS of the plurality of permitted TBS values. If it is determined that the selected TBS is lower than the maximum TBS, the method comprises selecting a time for starting the transmission of the random access procedure message from a plurality of permitted starting transmission times, and transmitting the random access procedure message to the infrastructure equipment in the allocated communications resources using the selected TBS.

摘要： A method and apparatus for provision of random access channel (RACH) related information for connection failure detection in a new radio access technology (NR) is provided. For example, a first gNB receives, from a wireless device, random access channel (RACH) related information and cell information for a radio link failure (RLF), and transmits, to a second gNB, the RACH related information and the cell information for the RLF. For another example, a gNB central unit (gNB-CU) of a first gNB receives, from a second gNB, RACH related information and cell information for RLF, and transmits, to a gNB distributed unit (gNB-DU) of the first gNB, information for an RACH configuration based on the RACH related information and the cell information for the RLF.

摘要： Methods, systems, and devices for wireless communication are described. Signaling of a radio frequency (RF) band associated with a synchronization signal (SS) block detected by a user equipment (UE) may be transmitted to a base station. For example, a base station may transmit a set of SS blocks to multiple UEs, where the SS blocks are frequency division multiplexed such that each SS block is transmitted in a respective RF band. A UE may receive one or more of the transmitted SS blocks and determine a preferred SS block from the received SS blocks. The UE may in turn transmit an message to the base station that indicates the RF band of the preferred SS block. In some cases, the base station may optionally transmit a request to the UE to transmit the indication of the RF band.

摘要： Systems and methods of the present disclosure are directed to a method. The method includes transmitting a Radio Resource Control (RRC) request or Scheduling Request (SR) via a random access procedure. The method includes receiving a Radio Link Control (RLC) Protocol Data Unit (PDU) including a RLC header and a RRC message, wherein the RLC header has an indication of an instruction to transmit an RLC status report. The method includes, responsive to transmitting, making a determination that a Wireless Communication Device (WCD) is to refrain from transmitting a SR via the random access procedure. The method includes, responsive to making the determination, transmitting a SR on Physical Uplink Control Channel (PUCCH) resource(s) of the PUCCH resource(s) indicated in the RRC message to obtain an uplink grant to transmit the RLC status report for the RLC PDU.

摘要： Systems, methods, and instrumentalities are disclosed for concurrent link setup and downlink data retrieval, e.g., for high efficiency WLAN. An access point (AP) may send a trigger element that allocates a resource for pre-association transmissions with the AP. The trigger element may allocate the resource for random access and/or deterministic access. The AP may receive, from an unassociated STA, a first frame via one or more resource units (RUs) allocated in the trigger element. The AP may determine a pre-association identifier (PID) that identifies the unassociated STA. The AP may send the PID to the unassociated STA, for example, in the trigger element or in the multi-STA ACK. The AP may send a second frame associated with a multi-user (MU) transmission that includes the PID. The AP may send a trigger frame that includes the PID.
