摘要： Systems and methodologies of reducing overhead by designating various fields in an optimized Radio Link Control header. Depending on communication type (e.g., VoIP, non-VoIP) such fields include a combination of a Segment Indicator (SI - which indicates presence of a whole SDU at beginning or at an ending), a Sequence Number (SN), a Length Indicator (LI - which indicates length of a service data unit); a length for the length indicator (LLI - to enable a variable size for the LI and notify a receiver regarding such varying size); a Segment Offset (SO - to designate resegmented packets for lost protocol data units); a length indicator for the SO (LSO - to enable a variable size for the SO); and Last Segment Flag (LSF - for resegmentation of RLC protocol data units).

摘要： Systems and methodologies are described that facilitate efficiently communicating a data packet related to a protocol layer within a wireless communication system. The systems and/or methods can provide cross-layer optimization by directly transporting or communicating data to a particular protocol layer. In general, a MAC header can include data that indicates a protocol layer to which such data is directed or targeted. The MAC header can allow a portion of data (e.g., PDUs, SDUs, etc.) to bypass at least one protocol layer above the MAC protocol layer for efficient and optimized processing of such data.

摘要： Techniques for performing in-order data delivery during handover in a wireless communication system are described. A user equipment (UE) may perform handover from a source base station to a target base station. The target base station may start a timer after a data path from a gateway to the UE has been switched from the source base station to the target base station. The target base station may receive forwarded packets for the UE from the source base station and may receive new packets for the UE from the gateway. The target base station may send the forwarded packets received prior to expiration of the timer to the UE before any new packets. The target base station may send the forwarded packets to the UE without waiting for the timer to expire and may send the new packets to the UE after the timer expires.

摘要： A method includes sending to a receiving device from a transmitting device a Radio Link Control (RLC) re-transmission scheme selected from a plurality of RLC re¬ transmission schemes, and using the selected and sent scheme at least at one of the receiving device and the transmitting device. In another exemplary non-limiting embodiment the method includes detecting, at the receiver, a gap in RLC Protocol Data Unit (PDU) sequence numbers, associating a timer with the gap, and starting the timer when the gap is detected. In still another exemplary non-limiting embodiment, the method includes detecting a gap in a RLC PDU sequence, monitoring a HARQ channel for a period of time to determine if a predetermined bit has changed, and determining if a transmission is lost.

摘要： To mitigate re-syncs, RLP sync control frames associated with a packet data session can be sequence numbered. A single sequence number can be assigned for an entire sync procedure associated with the initiation of a packet data session. For example, the sequence number can remains the same on all sync control frames (SYNC, SYNC/ACK, ACK) of a particular packet data session. When a sync frame is received out of order within a single sequence, it can be ignored under certain conditions. For example, if a SYNC frame with a sequence number 0 is received out of order after an ACK frame with sequence number 0 is received, the mobile station can ignore the out of order SYNC frame. Thus, an RLP re-sync is avoided due to out of order RLP sync packets.
摘要翻译：为了减轻重新同步，与分组数据会话相关联的RLP同步控制帧可以是序列号。可以为与分组数据会话的发起相关联的整个同步过程分配单个序列号。例如，序列号可以在特定分组数据会话的所有同步控制帧（SYNC，SYNC / ACK，ACK）上保持相同。当同步帧在单个序列内按顺序接收时，可以在某些条件下忽略同步帧。例如，如果在接收到序列号为0的ACK帧之后，如果接收到序列号为0的SYNC帧，则移动台可以忽略不合格的SYNC帧。因此，由于不期望的RLP同步分组，避免了RLP重新同步。

摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for coordinated scheduling of service periods (SPs). In some aspects, an access point (AP) may receive timing information indicating an SP associated with an overlapping basic service set (OBSS) and may transmit, to its associated STAs, coordinated timing information indicating the timing of the SP in relation to its timing synchronization function (TSF) timer. In some aspects, the AP may adjust the timing information to account for an offset between its TSF timer and a TSF timer associated with the OBSS. In some other aspects, the AP may synchronize its TSF timer with the TSF timer associated with the OBSS. The AP may further communicate with the STAs based on the coordinated timing information. For example, the AP may schedule communications with the STAs to be orthogonal to communications in the OBSS during the SP.

摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing data traffic in restricted target wake time (TWT) service periods (SPs). In some aspects, an access point (AP) may transmit a packet, at the beginning of a restricted TWT SP, that signals all non-member wireless stations (STAs) to defer access to the wireless medium for at least a threshold duration. Upon receiving the packet, any non-member STAs that are associated with the AP may set their network allocation vectors (NAVs) according to the duration indicated by a duration field of the received packet. In some implementations, low-latency STAs that are members of the TWT SP may not set their NAVs according to the duration field of the received packet. Instead, the low-latency STAs may access the wireless medium before the NAVs associated with the non-member STAs expire.

摘要： In some implementations, an access point (AP) establishes a restricted target wake time (TWT) session including at least one restricted TWT service period (SP) for peer-to-peer (P2P) communications. The AP admits a group of wireless stations (STAs) associated with P2P communications as members of the restricted TWT session, obtains a transmission opportunity (TXOP) on the wireless channel during the at least one restricted TWT SP, and transmits, on the wireless channel, a protection frame identifying one or more STAs of the group of STAs belonging to the restricted TWT session that are permitted to transmit or receive P2P communications on the wireless channel during the TXOP. The protection frame may also indicate to receiving devices other than the one or more identified STAs that the wireless channel is unavailable for at least a portion of the TXOP.

摘要： This disclosure provides methods, devices and systems for transmitting and receiving physical protocol data units (PPDUs) over multiple links. In some aspects, a wireless communication device may determine that first random back off (RBO) for a first channel of a first link has counted down to zero. A wireless communication device may determine, when the first RBO has counted down to zero, that a second RBO for a second channel of a second link has a count down remaining. A wireless communication device may optionally transmit a medium reservation message on the first link reserving a transmission opportunity (TXOP). A wireless communication device may determine whether to wait for the second RBO before transmitting on the first link. A wireless communication device may transmit at least a first PPDU on the first link during the TXOP.

摘要： This disclosure provides methods, devices and systems for sharing resources of a wireless medium. Particular implementations relate more specifically to coordinated AP (CAP) time-division-multiple-access (TDMA) and orthogonal-frequency-division-multiple access (OFDMA) techniques for sharing the time or frequency resources of a transmission opportunity (TXOP). According to such techniques, an AP that wins contention and gains access to the wireless medium for the duration of a TXOP may share its time or frequency resources with other selected APs. To share its resources, the winning AP may partition the TXOP into multiple time or frequency segments each including respective time or frequency resources representing a portion of the TXOP, and allocate each of the time or frequency segments to itself or to one of the selected APs.
