摘要： Embodiments herein relate to a method in a mobile terminal for requesting access to a wireless communication system. The mobile terminal receives broadcasted system information directly indicating first access request preambles for a first contention based channel, and indirectly indicating second access request preambles for a second contention based channel based on the directly indicated first access request preambles. The mobile terminal further derives the second access request preambles from the first access request preambles. Additionally, the mobile terminal requests access using the second access request preambles or the first access request preambles to access the wireless communication system.

摘要： According to the invention data in a number of logical downlink intended for one or more mobile terminals are received in a first mapping unit, where at least a first High Speed Radio Network Temporary identity is allocated to these logical downlink channels addressing a group of mobile terminals for allowing transmission of channel data for reception by mobile terminals. A mobile terminal then reads, from a Broadcast Control Channel, necessary information including a High Speed Radio Network Temporary identity allocated to at least one logical downlink channel, where at least said first identity exists among possible identities. It then listens to a high speed shared control channel for the read identity. In case it detects the identity, the terminal follows a scheduling command, receives data on a high-speed downlink shared channel and processes said data.

摘要： A transmitter that may have marginal power availability is enabled to autonomously retransmit previously transmitted frames containing the same data. The transmitter sends an initial frame to a base transceiver station (BTS) and immediately retransmits the same frame without regard to any ACK/NAK transmission from the BTS. The retransmissions are accumulated in the receiver and decoded after a sufficient quantity of the frame is transmitted. After receiving the last retransmitted frame the BTS sends an ACK/NAK to the transmitter that is accepted.
摘要翻译：可以具有边缘功率可用性的发射机能够自主地重传包含相同数据的先前发送的帧。发射机向基站收发台（BTS）发送初始帧，并且立即重发相同的帧，而不考虑来自BTS的任何ACK / NAK传输。在传送足够量的帧之后，重传在接收机中累积并被解码。在接收到最后一个重传帧之后，BTS向被接收的发射机发送ACK / NAK。

摘要： In a wireless communication network where base stations receive protocol data units (PDUs) from mobile stations for decompression and deciphering for ordered, sequential transfer as service data units (SDUs) to an associated core network, the teachings presented herein provide a method of supporting seamless handover of a mobile station from a source base station to a target base station. By way of example, the teachings herein apply to a network based on the E-UTRA specifications, as promulgated by the 3GPP. However, that example is non-limiting, as the teachings herein apply to any network that employs in-sequence data delivery and duplicate data detection at handover. Broadly, the source base station forwards out-of-sequence SDUs and corresponding sequence number information to the target base station in support of seamless handover, and the target base station uses that information to request retransmissions as needed for packet reordering.

摘要： Methods, apparatus, and systems for measuring, on a per-QoS-class basis, the average number of user devices active on the uplink of a wireless communication system are disclosed. In an exemplary method, a number of mobile terminals with buffered data for transmission to a base station is estimated based on received buffer status reports. An estimated quantity of active mobile terminals is calculated, based on the received buffer status reports and a number of mobile terminals for which a semi-persistent scheduling grant has been granted. In some embodiments, the estimated quantity of active mobile terminals is estimated on a per-traffic-class basis, in which case the technique includes calculating first and second estimated quantities, corresponding to mobile terminals having active data bearers for first and second traffic classes, respectively, based on the received buffer status reports and the number of mobile terminals for which a semi-persistent scheduling grant has been granted.

The mobile terminal receives broadcasted system information that indicates a first available resource of a contention based channel. The mobile terminal derives a second available resource of the contention based channel based on the first available resource of the contention based channel. The mobile terminal further transmits an access request preamble mapped to the second available resource to access the wireless communication system.

摘要： A Level-1 (L1) signaling flag is mapped to unused (invalid) bit sequences in Part 1 of the HS-SCCH—that is, Part 1 bit encodings that are not defined in the UTRAN specifications—and a corresponding L1 command is encoded in Part 2. This allows UE (18) to detect early that the HS-SCCH is pure L1 signaling, and the UE (18) may avoid wasting power by not processing an accompanying HS-PDSCH. Alternatively, in CPC HS-SCCH-less mode, the UE (18) may blind decode the HS PDSCH. In one embodiment, a general DRX mode is defined and controlled via L1 signaling. In one embodiment, a UE (18) acknowledgement improves the L1 signaling accuracy. In one embodiment, a L1 signal and UE (18) acknowledgement protocol are utilized to “ping” a UE (18).
