Abstract:
Aspects of the present disclosure provide a method for wireless communications by a peer device. The method generates control information to schedule peer-to-peer communication. The control information includes a first portion with a first set of data and a second portion with a second set of data. The method then transmits the first portion of the control information in a first stage using first time and frequency resources. The first portion indicates a control information format of the second portion. The method further transmits the second portion of the control information in a second stage using second time and frequency resources and the indicated control information format.
Abstract:
Methods, systems, and devices for wireless communications are described. In some systems (e.g., sidelink systems, such as vehicle-to-everything (V2X) systems), wireless devices may perform dynamic resource reservations to schedule packet transmissions (e.g., data packet transmissions). Different packets may correspond to different priority levels. To support flexible resource reservation for high priority packets, wireless devices may implement techniques for preempting lower priority reservations. For example, a wireless device may identify reservations for transmitting different packets during a same transmission time interval (TTI). The device may determine whether a first or second packet has a higher relative priority and may communicate in the V2X system during the TTI according to the relative priorities. For example, a device that reserved the TTI for the lower priority packet may refrain from transmitting the packet during the TTI, while a device that reserved the TTI for the higher priority packet may transmit the packet.
Abstract:
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may utilize priority levels associated with packets or transmissions to determine whether to transmit feedback for a received transmission. The UE may compare priority levels between a transmission subject to a feedback condition and a transmission scheduled to be received when the feedback is scheduled to be transmitted to determine whether to send the feedback. The UE may communicate with the transmitting device according to the comparison and the determining. The UE may determine signal conditions causing a NAK and determine to send the NAK based on the signal conditions.
Abstract:
Various aspects are provided related to techniques for signal extension (SE) signaling. A signal extension (SE) duration for a data unit can be identified from a set of at least three possible SE durations. A single signaling bit in the data unit can be used to indicate the identified SE duration from the set of at least three possible SE durations to a receiver of the data unit. The data unit can be output for transmission to the receiver.
Abstract:
Methods and apparatus for single and multi-user signal extensions or padding are provided. In various aspects, a number of symbols required to transmit a plurality of data bits to each of a plurality of wireless communication devices and a fraction of useful bits in a final symbol of each of the plurality of data bits is determined. A signaling extension length may also be determined based at least in part on the fraction of useful bits and a modulation and coding scheme (MCS) of each of the plurality of wireless communication devices. A plurality of data packets for each of the plurality of wireless communication devices are generated, with each data packet comprising the corresponding data bits and the signaling extension after the final symbol of each of the plurality of data packets.
Abstract:
Methods, apparatuses, and computer readable media for resource allocation signaling in a high efficiency wireless local area network (WLAN) are disclosed. A transmitter may generate an indication that a first channel of a plurality of channels associated with a transmission frame has been punctured, the transmission frame including a WLAN signaling field. The transmitter may identify information associated with the WLAN signaling field corresponding to the punctured first channel. The transmitter may transmit the information associated with the WLAN signaling field in a second channel of the plurality of channels. The transmitter may transmit the indication that the first channel has been punctured in the second channel or in a second WLAN signaling field of the transmission frame.
Abstract:
Methods and apparatuses relating to wireless communication of a user equipment (UE) are provided including receiving downlink wireless communications from multiple cells in an active set, receiving at least one of scheduling information for one or more downlink transmissions or one or more non-serving resource grants from a first cell in the active set, and receiving one or more serving resource grants for uplink communications from a second cell in the active set. In the wireless network, a second cell can be assigned as an uplink serving cell for uplink communications with the UE that is different from a first cell assigned as a downlink serving cell for downlink communications with the UE, and downlink transmissions can be scheduled from the downlink serving cell to the UE, and/or one or more serving resource grants can be transmitted from the uplink serving cell to the UE.
Abstract:
Resource allocation signaling in a high efficiency wireless local area network (WLAN) is disclosed. An access point (AP) may generate a resource unit (RU) size indicator in a first WLAN signaling field, the RU size indicator decodable by a set of stations. The AP may also generate a common user field in a second WLAN signaling field, such that a size of the common user field may be based on the RU size indicator of the first WLAN signaling field. The AP may generate a station-specific field in the second WLAN signaling field, such that a position of the a station-specific field corresponds to one or more RUs associated with the a station-specific field. The AP may then transmit a WLAN preamble that includes the first WLAN signaling field followed by the second WLAN signaling field.
Abstract:
Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In some particular aspects, scheduling of the uplink MIMO transmissions may make a determination between single stream, rank=1 transmissions and dual stream, rank=2 transmissions based on various factors. Further, when switching between single and dual stream transmissions in the presence of HARQ retransmissions of failed packets, the scheduling function may determine to transmit the HARQ retransmissions on a single stream transmission or to transmit the HARQ retransmissions on one stream while transmitting new packets on the other stream.

A method that includes determining a multi-flow configuration for a multi-flow communication of a user equipment (UE), wherein the multi-flow configuration identifies whether a multi-frequency configuration is utilized and whether multiple-input multiple-output (MIMO) communication is configured for at least one cell in the multi-flow communication, determining one or more cell groups based on the multi-flow configuration, and determining at least one of a channel quality indicator (CQI) repetition rule or a hybrid automatic repeat request acknowledgment (HARQ-ACK) repetition rule for the multi-flow communication based on one or more of the multi-flow configuration or the one or more cell groups.
