Abstract: A first communication device transmits a null data packet (NDP) to a second communication device as part of a multi-user beamforming training transmission sequence and receives a first packet from the second communication device responsive to transmitting the NDP. The first packet includes an aggregate media access control protocol data unit (A-MPDU) having a plurality of fragments of beamforming training information that was generated by the second communication device based on the NDP. The first communication device determines that one or more of the fragments were not correctly received by the first communication device and generates a bitmap to indicate a set of at least one fragment that is to be retransmitted by the second communication device. The first communication device transmits a second packet having the bitmap to the second communication device to prompt the second communication device to retransmit the set of at least one fragment.

Abstract: Aspects of the present disclosure provide techniques for end-to-end rate adaptation using radio access network (RAN) assisted rate adaptation. Particularly, when a user equipment (UE) risks operating at rates greater than the guaranteed bit rates (GBR), the UE may rely on rate adaptation mechanisms to indicate when it has exceeded the supported bandwidth such that the UE may reduce its rate accordingly. Specifically, in some examples, a network device (e.g., call session control function (CSCF) and/or policy and charging rules function (PCRF)) may configure endpoints in an end-to-end communication to operate at rates that exceed GBR based on determining that all endpoints support RAN assisted rate adaptation capability. In other examples, the network device may configure maximum bit rates (MBR) that exceed GBR for only the endpoint that supports RAN assisted rate adaptation capability.

Abstract: A wireless device initiates a random access procedure on an unlicensed cell. A listen-before-talk (LBT) procedure, for transmission of a preamble of the random access procedure, is performed. In response to the LBT procedure indicating a clear channel, the wireless device: transmits the preamble via a random access channel (RACH) of the unlicensed cell, and monitors a physical downlink control channel (PDCCH) for a random access response (RAR). In response to the LBT procedure indicating an LBT failure, the wireless device: does not monitor the PDCCH for the RAR, and performs a random access resource selection procedure.

Abstract: A method of communicating data between a radio network infrastructure and a terminal device in a wireless telecommunications network. The method comprises establishing at a radio network infrastructure element there is data available for communication between the radio network infrastructure and the terminal device and transmitting a paging message for the terminal device from the radio network infrastructure element. The paging message comprises an indication of an identifier for the terminal device and an indication of a network allocated resource for use in subsequently communicating the data between the radio network infrastructure element and the terminal device. In response to receiving the paging message the terminal device transmits to the radio network infrastructure element a paging response indicating the terminal device received the paging message, after which the data is communicated between the radio network infrastructure element and the terminal device using the network allocated resource.

A user terminal that communicates with a cell that uses at least a reduced TTI shorter than a period of a subframe includes: a reception section that receives from the cell a report request that triggers channel state information (CSI) reporting; and a control section that controls the CSI reporting in a subframe unit or a short TTI unit based on the report request.

Abstract: Methods and systems are provided in which a UE transmits sidelink (SL) control information comprising a scheduling assignment (SA) indicating an SL transmission resource for a SL data transmission to a target UE. The SL transmission resource is based on one or more occupied SL resources identified by the UE and the SL transmission resource includes resources for an initial transmission and one or more retransmissions. The UE then transmits the SL data transmission using the SL transmission resource according to the transmitted SL control information. This is done without receiving, in a downlink control information (DCI), a grant of communication resources.

Abstract: Systems, methods, and apparatus for operating RAN and CN nodes are disclosed. An example method of operating a RAN node includes receiving, from a CN node, a PDU for a wireless device that is in an inactive state. The RAN node pages the wireless device in response to receiving the PDU from the CN node. The RAN node sends a non-delivery message to the CN node in response to failure of the paging for the wireless device, where the non-delivery message includes an indication that the wireless device is in the inactive state. An example method of operating a CN node includes the CN node sending a PDU for a wireless device to a RAN node. The CN node then receives a non-delivery message from the RAN node, where the non-delivery message includes an indication that the wireless device is in an inactive state.

Abstract: In the examples described herein, a user equipment (UE) may identify multiple carriers configured for communications with a base station, and the UE may group the carriers into one or more preferred groups for synchronized scheduling at the base station. The preferred groups of carriers for synchronized scheduling may represent a recommendation that carriers within a preferred group are to be scheduled for communications with the base station on at least partially overlapping resources to maximize power savings at the UE. The UE may transmit an indication of the preferred groups of carriers to the base station, and the base station may identify an actual group of carriers for synchronized scheduling based on the indication received from the UE. The base station may then schedule communications with the UE based on the actual group of carriers.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, randomized shifts of a base sequence may be used for transmitting uplink control information. For example, a user equipment (UE) may identify a base sequence of an uplink control message. The UE may also receive signaling that indicates a UE-specific initial shift that may be applied to the base sequence. In some examples, the signaling that indicates the randomized shift may be explicit, implicit, or a combination thereof. After determining one or more shifted sequences based on the UE-specific initial shift, a payload of the uplink control message, and the base sequence, the UE may select a shifted sequence to be transmitted, where the selection is based on a payload of the uplink control message. For example, different shifted sequences may be selected for respective transmissions of scheduling requests, 1-bit acknowledgments (ACKs), 2-bit ACKs, and the like.
