摘要： In accordance with one or more embodiments and corresponding disclosure thereof, various aspects are described in connection with providing shared scheduling request (SR) resources to devices for transmitting SRs. Identifiers related to the shared SR resources can be signaled to the devices along with indications of the shared SR resources in given time durations. Thus, devices can transmit an SR over shared SR resources related to one or more received identifiers for obtaining an uplink grant. This can decrease delay associated with receiving uplink grants since the device need not wait for dedicated SR resources before transmitting the SR. In addition, overhead can be decreased on control channels, as compared to signaling dedicated SR resources and/or uplink grants. Moreover, identifiers related to SR resources can correspond to a grouping of devices, such that a device can transmit over shared SR resources related to a group including the device.

摘要： Systems and methodologies are described that facilitate compressing headers for relay nodes. In particular, a robust header compression (RoHC) profile can be defined for general packet radio service (GPRS) tunneling protocol (GTP) headers. Upon receiving a packet with one or more GTP headers, an access point or relay node can determine whether the one or more GTP headers are compressible and can apply the RoHC profile to compress the one or more GTP headers. In addition, the packet can include a baseheader encapsulated by the one or more GTP headers, which can also be compressed according to a RoHC profile specific to the baseheader. Moreover, RoHC compressed headers can be decompressed according to the GTP RoHC profile.

摘要： This innovation relates to systems and methods for transmission of protocol data units, and more particularly to processing polling requests from a radio link control peer. A radio link control transmitter can poll a receiver to obtain a report regarding the status of a set of data packets, and the polls can be sent in-band with a data packet. The receiver can determine to wait before sending the status report based on one or more characteristics of the received data packets.

摘要： Systems and methodologies are described that facilitate employing a variety of medium access control (MAC) header formats in wireless communications. The MAC header formats can be specialized for a particular type of data included in a protocol data unit (PDU). In addition, the MAC headers can have a variable length to accommodate payloads of varying sizes without incurring unnecessary overhead. Further, mechanisms are provided to enable direct access and delivery of control PDUs to associated protocol layers to ensure better quality of service treatment.

摘要： 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.

摘要： Methods and apparatuses are provided that facilitate providing quality of service for similar priority logical channels at least in part by assigning dynamic priority levels to the logical channels to allow certain logical channels to be assigned resources before other logical channels. Dynamic priority levels can be assigned based at least in part on a total accumulated used bytes of a given logical channel scaled by a prioritized bit rate of the logical channel. Thus, logical channels with a lower number of total accumulated used bytes scaled by the prioritized bit rate can be assigned higher priority to ensure resources are assigned to the logical channels. Moreover, the dynamic priority levels can be normalized to align the dynamic priority levels within certain values so as not to interfere with other logical channels of different assigned priority.

摘要： Techniques are provided for efficiently reestablishing connection between peer-to-peer devices. For example, there is provided a method for peer-to-peer (P2P) connection reestablishment by a mobile device.

摘要： Systems and methodologies are described that facilitate packet discard restriction in a wireless communication system. As described herein, a discard prohibit counter and/or other similar mechanism can be employed to limit the number of consecutive packets that are discarded by a transmitter, even in the event that the delay bounds of those packets have been exceeded. A discard prohibit counter as described herein can be updated upon a packet transmission and reset upon a packet discard to ensure that an acceptable number of packets are transmitted before a packet can be discarded. An acceptable number of packets can be selected based on device specifications, requirements of a data packet flow and/or traffic associated with the flow, or other suitable factors, and can be constant or adaptable to changes in network conditions. As further described herein, multiple counters can be separately maintained and utilized for a plurality of corresponding packet flows.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided in which a difference between a previous power management maximum power reduction (P-MPR) and a current P-MPR is determined. The previous P-MPR is the P-MPR when an indication is communicated that a power backoff is applied due to the previous P-MPR. A power headroom report (PHR) is triggered when the difference is greater than a threshold and the current P-MPR is greater than a sum of a maximum power reduction (MPR) and an additional MPR (A-MPR). Moreover, an apparatus is provided in which whether and how a P-MPR has changed is indicated in a PHR, and the PHR is transmitted. An apparatus is also provided in which a request is received from an evolved Node B (eNodeB) to report a P-MPR, and a PHR is transmitted including information related to the
