Abstract: Systems and methodologies are described that facilitate providing flow control feedback for controlling downlink data transmission rates. Various schemes can be utilized to send the flow control feedback from an access terminal to a base station. For example, a control PDU (e.g., MAC control PDU, PDCP control PDU) can be generated based upon a level of resource utilization of the access terminal, and sent to the base station for controlling the downlink data transmission rate. Following this example, a type of control PDU, a value included within the control PDU, etc. can be selected as a function of the level of resource utilization. By way of another illustration, a CQI report that includes a value selected as a function of the level of resource utilization associated with the access terminal can be generated and transmitted to the base station for controlling the downlink data transmission rate.

Abstract: Systems and methodologies are described that facilitate utilizing timers in conjunction with transmitting buffer status reports (BSR). A prohibit timer can be utilized to determine when BSRs can be transmitted to an eNB. The prohibit timer can be initialized or restarted upon transmitting a BSR to an eNB. A BSR retransmit timer can be used to determine when to retransmit a BSR. The BSR retransmit timer can be initialized upon transmitting a BSR to an eNB and restarted each time an uplink resource allocation is received from the eNB. Once the timer expires, if an uplink transmission buffer contains data (e.g., size>0), the BSR can be retransmitted to the eNB. Control data feedback can additionally be used to determine when to retransmit the BSR. In addition, in either case, the timer duration values can be provided by the eNB.

Abstract: This disclosure provides methods, components, devices and systems for providing information with respect to co-existence conditions. Some aspects more specifically relate to providing co-existence condition information via response messages. In some examples, co-existence condition information provided via a response message may indicate that a wireless communication device is experiencing a co-existence condition, may include information regarding the co-existence condition, or a combination thereof. Response messages utilized in carrying co-existence condition information may include messages made in response to a message from a peer wireless communication device via an existing or otherwise prior established messaging channel established for messaging of information other than co-existence condition information.

Abstract: This disclosure provides methods, devices and systems for protecting latency-sensitive communications, during restricted target wake time (r-TWT) service periods (SPs), from non-legacy STAs that do not support r-TWT operation. Some implementations more specifically relate to preventing STAs that are not members of an r-TWT SP from acquiring transmit opportunities (TXOPs) that would otherwise overlap with the start of the r-TWT SP. In some implementations, the AP may require all non-legacy STAs associated with its basic service set (BSS) to support r-TWT operation. In some other implementations, the AP may attempt to capture a wireless channel associated with the r-TWT SP within a fixed period preceding the r-TWT SP. In some other implementations, the AP may require all associated STAs to transmit a request-to-send (RTS) frame when attempting to acquire a TXOP. Still further, in some implementations, the AP may limit the duration of TXOPs acquired by non-member STAs.

Abstract: This disclosure provides methods and devices for managing the allocation of resources for uplink (UL) and downlink (DL) transmissions associated with a scheduled time period. In some implementations, a wireless station (STA) transmits, to an access point (AP), a request frame indicating a bandwidth or a quantity of spatial streams (or both) for the UL transmissions, and indicating a bandwidth or a quantity of spatial streams (or both) for the DL transmissions. In some instances, the request frame also may indicate the STA's intention to transmit UL data as duplicates carried on different communication links. The STA receives a trigger frame indicating that the STA is scheduled to transmit or receive data during the time period. The STA transmits data to, or receives data from, one or more other devices during the time period.

Abstract: Various aspects of the techniques, methods and devices described in this disclosure relate generally to achieving coexistence between WLAN and P2P networks, and specifically, to coordinated D2D communications. Some aspects particularly involve extending the capabilities of TWT elements transmitted by APs to support periodic reserved access windows during which D2D-enabled wireless devices are permitted to transmit direct wireless communications. Some other aspects relate to sharing time and frequency resources via CAP TDMA or CAP OFDMA techniques, and specifically, to allocating at least some of the time and frequency resources specifically for D2D communications. Some other aspects relate to periodic coordinated access windows during which APs are scheduled to contend but during which D2D devices are not permitted to contend, and specifically, to scheduling a reserved access window within a periodic coordinated access window during which D2D devices may transmit direct communications to other D2D devices despite the permissions associated with the periodic coordinated access windows.

Abstract: This disclosure provides methods, components, devices and systems for wireless packet header protection. Some aspects more specifically relate to supporting header integrity checks to prevent processing of maliciously altered packet headers. In some examples, a wireless communication device may generate header integrity check information based on one or more fields of a header of a first data packet. The wireless communication device may generate, based on the header integrity check information, the first data packet or a second data packet. For example, the header of the first data packet may include the header integrity check information, or a value derived therefrom. Alternatively, the header integrity check information (or the derived value) may be included in a subsequently transmitted packet (e.g., the second data packet) A receiving device may use the received header integrity check information to perform a header integrity check before processing the header of the first data packet.

Abstract: This disclosure provides methods, devices and systems for communicating over multiple links, for example, indicating buffered units (BUs) per traffic identifier (TID) for transmission to multi-link devices (MLDs). One innovative aspect of the subject matter described in this disclosure can be implemented in a method for wireless communication. The method can be performed, for example, by a non-access point (non-AP) MLD. The non-AP MLD can receive an indication of an association identifier (AID) associated with the non-AP MLD, wherein the indication of the AID indicates whether an AP has BUs for the non-AP MLD, determine one or more links associated with one or more TIDs based on a mapping of a plurality of TIDs, including the one or more TIDs, to a plurality of links, including the one or more links, receive the BUs associated with the one or more TIDs from the AP on the determined links.

Abstract: This disclosure provides methods, components, devices and systems for link parameter recommendation in a wireless local area network. A first and second wireless communication device may communicate via one or more links. The second wireless communication device may use a first set of communication parameters to communicate with the first wireless communication device, and the first wireless communication device may determine that communication with the second wireless communication device using the first set of communication parameters fails to satisfy one or more criteria. Responsive to the determination, the first wireless communication device may transmit an indication for the second wireless communication device to use a second set of communication parameters for communicating with the first wireless communication device after which the first and second wireless communication device may communicate one or more frames.
