Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may support multicast transmissions from a base station to multiple user equipments (UEs). Each UE may have uplink resources allocated for providing feedback to the base station regarding multicast transmissions. For example, a UE may not successfully decode one or more frames of a multicast transmission. When a UE does not successfully decode the one or more frames, the UE may transmit negative acknowledgment (NACK) feedback indicating the one or more frames that were not successfully received. A serving base station may store frames within a buffer for a transmission window and retransmit each of the frames indicated within the NACK feedback from the stored frames. In some cases, the serving base station may not retransmit frames that were not indicated within the NACK feedback (e.g., frames that may have been received successfully by the UE).

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for efficiently managing groups of stations (STAs) receiving simultaneous transmissions in a multiuser multiple-input multiple-output (MU-MIMO) scheme. One example method generally includes; for a first apparatus in a number of groups of apparatuses, allocating a first spatial stream position for each of at least one first group in the number of the groups; and transmitting a first unicast message to the first apparatus, wherein the first unicast message comprises an indication of the allocated spatial stream position for each of the at least one first group and, for each group in the number of the groups, an indication of a membership status, in the group, of the first apparatus.

Abstract: Various features pertain to mitigating interference on downlink/uplink channels caused by bursty traffic transmissions. A transmitting node encodes data into transport blocks, each including code blocks in which the data is encoded. The transport blocks are then wirelessly transmitted over a channel specific to a receiving node, where the code blocks of the transport blocks are transmitted without redundant parity code blocks or with a desired amount of redundant parity code blocks. The transmitting node then receives an indication from the receiving node of a number of failed data code blocks. The transmitting node generates an error correction code sufficient to recover all of the failed code blocks and transmits the error correction code within a new transport block along with new data.

Abstract: Devices and methods for synchronized group messaging in a wireless communication system are described. Multicast transmissions, such as those in a dense network, can cause significant medium usage because same multicast packet is likely sent by multiple APs at different time. Medium usage in such implementations may be redundant. As such, the transmission medium is not used optimally. Devices and methods which coordinate and align group messages (e.g., multicast packets) amongst APs are described. Each AP may be configured to transmit identical packets at the same time. Therefore, medium usage can be reduced, while the range can be extended due to accumulated energy from APs.

In one aspect, a first station discovers a second station capable of providing a service of interest to the first station. The second station is one of a plurality of stations participating in a NAN data link network that provides the service of interest and supports communication over a NAN data link channel without beaconing. The second station is discovered through communication over a NAN channel supported by a plurality of neighborhood stations forming a NAN network. The NAN channel has a beaconing operation that provides synchronization. After discovery of the second station, the first station communicates with the second station over the NAN data link channel, to obtain data corresponding to the service of interest.

Abstract: Methods, systems, and devices for wireless communication are described. Stations within a neighborhood awareness network (NAN) may determine when to transmit synchronization beacons during a wake-up time based on some priority (e.g., stations with more recent clock updates or earlier time stamps, stations communicating with a larger number of peers or associated with a larger number of NAN device links (NDLs), etc. may transmit beacons earlier in a wake-up window or with a higher probability). Other stations within the NAN may maintain clock synchronization based on the transmitted beacons (e.g., that include recently updated clock information). Additionally or alternatively, a station may signal other stations within a NAN when the station detects disappearance of synchronization beacons (e.g., or loss of clock synchronization). In some cases, the signaling may include requests for the one or more other stations to start or stop beacon transmissions as desired.

Abstract: A method includes sending, from a first transmitter to a first receiver, a request to send (RTS) message associated with a first transmit opportunity (TXOP). The RTS message requests the first receiver to indicate whether reuse of the first TXOP is permitted. The method further includes receiving, at the first transmitter from the first receiver, a clear to send (CTS) message responsive to the RTS message.

Abstract: A method, a user equipment, a 5G core network device, an apparatus, and a computer program product for wireless communication are provided. Battery life and network efficiency of the user equipment are improved through the usage of a polled-mode power saving technique, wherein the user equipment periodically awakens to poll the 5G core network device regarding whether a communication is available for the user equipment. If the communication is available, the user equipment receives the communication. If the communication is delayed, the user equipment performs discontinuous reception to save power until the communication is available. If the communication is unavailable, the user equipment resumes a sleep mode.

Abstract: A core network receives data from at least one of an Application Function (AF), a Data Network (DN), or a User Equipment (UE). A Session Management Function (SMF) processes the data for transport with a low overhead as a session management (SM) payload over a Non Access Stratum (NAS) protocol.

The data may be received as uplink data from a UE, e.g., in an SM payload. The SMF may processed the SM payload to obtain the data and may transport the data to the AF or DN. The SMF may perform IP header compression, data encryption based on an SMF encryption key, and/or buffering of data for a UE in an idle mode.
