摘要： A method for contention-based (CB) uplink transmission in a wireless communication network is provided. A base station (eNB) first transmits CB configuration information and CB grant to a user equipment (UE). The UE derives a plurality of transmission opportunities from the uplink CB grant and in response transmits uplink CB data via one of the transmission opportunities. The UE then receives an acknowledgment from the serving base station. If the uplink CB data is non-decodable by the eNB due to multiple contention UEs, then the UE retransmits the uplink data in response to a negative acknowledgment. In one novel aspect, the uplink transmission radio resource carriers both the uplink CB data and UE-selected signature information. In one embodiment, the UE-selected signature information is transmitted via pilot tones. By eliminating a separate phase of contention resolution, the overall latency of CB transmission is reduced and transmission efficiency is improved.
摘要翻译：提供了一种在无线通信网络中基于争用（CB）上行链路传输的方法。基站（eNB）首先向用户设备（UE）发送CB配置信息和CB授权。 UE从上行链路CB授权中导出多个传输机会，并且响应于传输机会中的一个发送上行链路CB数据。然后，UE从服务基站接收确认。如果上行CB数据由于多个争用UE而被eNB无法解码，则UE响应于否定确认重发上行链路数据。在一个新颖的方面，上行链路传输无线电资源承载上行链路CB数据和UE选择的签名信息。在一个实施例中，经由导频音发送UE选择的签名信息。通过消除争用解决的单独阶段，CB传输的总体延迟降低，传输效率提高。

摘要： A method of power management for a mobile station in a multi-carrier wireless network is provided. A primary connection between the mobile station and a serving base station is first established by performing initial ranging over a primary radio frequency (RF) carrier. A secondary connection between the mobile station and the base station is then established by performing periodic ranging over a secondary RF carrier. To achieve efficient power management, the mobile station performs Open Loop Power Control and obtains long-term link measurement (CSI) of the primary carrier. The mobile station then adjusts carrier-specific parameters based on the primary carrier CSI. For RF carriers that convey on-going data traffic, Close Loop Power Control is updated per RF carrier. When the mobile station enters sleep mode operation, it receives traffic indication messages on the primary RF carrier and then dynamically wakes up one or more corresponding RF carriers for data reception.

摘要： Two preamble partition schemes are provided for flexible network deployment and efficient utilization of limited cell identification resources in a wireless network. In a soft partition scheme, the entire preamble sequences are partitioned into several configurable non-overlapping subsets, and each subset is associated with a corresponding cell type. In a hybrid partition scheme, a combination of fixed and configurable subsets is used for preamble partition. The partitioning information is carried in a broadcasting channel broadcasted from base stations to mobile stations. In one embodiment, after a mobile station performs scanning and synchronization with a first base station, it derives the cell type of the first base station from cell identification and partitioning information. The mobile station completes ranging and network entry with the first base station if the cell type is preferred, and starts to perform scanning and synchronization with a second base station if the cell type is non-preferred.

摘要： A Femto Base Station (FBS) includes a communication functionality and a reliability functionality. A control entity within the reliability functionality detects an FBS reliability compromising event (for example, an unscheduled loss of external power to the FBS). As a result of detecting the FBS reliability compromising event, the control entity sends a message (an “FBS Reliability Compromising Event Compensation Message” or “FBSRCECM”) to the communication functionality. The FBSRCECM initiates an action that compensates for the FBS reliability compromising event. In many examples, the action is the initiating of a handover from the FBS to another base station. The reliability functionality typically includes a rechargeable battery that powers the FBS for a time until the handover is completed gracefully. By performing a graceful handover, cellular network reliability is improved as compared to situations in which a conventional FBS simply stops working and connections handled by the conventional FBS are broken.

摘要： Methods and systems for providing fast handoff in WLAN-like communications system construct a caching candidate set based upon a weighted handoff tendency coefficient. The weighted handoff tendency coefficient is based upon the handoff matrix and the weighting factor. The handoff matrix is an adaptive two-dimensional array that provides a list of nearby access points relative to a mobile station and the weighting factor is a value that prioritizes the nearby access points based upon a signal quality indication. A home access point, once it is triggered to initialize proactive caching, provides the caching candidate set with registration data of the mobile station before a transfer of a connection between the home access point and one of the access points on the caching candidate set.

摘要： This invention provides a method for power-efficient transmission supporting integrated service over WLAN. The said invention combines the polling-based and the contention-based mechanisms, named on-demand polling (ODP). In the ODP scheme, a voice station is in the polling list when it is in the active mode. During the idle mode, it is configured to operate in the sleep mode for saving power. Also, it adopts the contention-based mechanism to join the list again while returning from the idle mode. On the other hand, the data station adopts the contention-based mechanism to transmit its packets over WLAN. In addition, to achieve service differentiation, the said invention also employs a prioritized access probability for voice over data services. Simulation results show that the said invention can reduce the power consumption for voice stations and enhance the throughput for data stations.

摘要： A method of managing multiple timing advance (TA) groups, maintaining multiple TA timers, and performing UL synchronization in a multi-carrier wireless system is provided. When a new component carrier (CC) is configured, it is assigned to a TA group having a TA group identifier. The TA groups are managed statically or dynamically. The TA group identifier is used to uniquely identify the TA group in the operations of uplink (UL) timing synchronization. Multiple TA timers are assigned to multiple TA groups. The TA timers may have different values for different TA group. Different embodiments of UL timing adjustments for multiple TA groups are provided.

摘要： A method of establishing a sleep mode operation between a mobile station and its serving base station is provided in a wireless communications system. When sleep mode operation is active, the MS enters into a series of sleep cycle and each sleep cycle comprises a listening window followed by a sleep window. In one novel aspect, each sleep cycle is associated with a set of sleep cycle parameters including a Sleep Cycle Length and an adjustable Listening Window Length. Each set of sleep cycle parameters is determined based on a predefined traffic characteristic of a data communication flow between the MS and it serving BS. Different embodiments of sleep cycle parameters are provided for real-time traffic, non-real-time traffic, real-time and non-real-time mixed traffic, and multi-rate transmission traffic. By using sleep cycle-based parameters, the efficiency of sleep mode operation is improved.

摘要： In a Hybrid Automatic Repeat ReQuest (HARQ) communication system, a receiver receives from a transmitter a HARQ sub-burst. A retransmission counter (RE_TX_CNT) in the receiver is incremented if either: (i) the receiver cannot decode the sub-burst, or (ii) no retransmission of the sub-burst is received within a Predetermined Retransmission Delay (PRD) interval. If RE_TX_CNT reaches a Maximal Retransmission Count (MAX_RE_CNT), then information for the sub-burst that was previously stored for HARQ purposes in a soft combining buffer in the receiver is flushed. Parameters that set the PRD interval and the MAX_RE_CNT value are pre-negotiated between the transmitter and the receiver. In another embodiment, if a novel timer in the receiver indicates that a first threshold time has elapsed after receipt of an undecodable HARQ transmission then buffered information is marked, whereas if the timer indicates that a second threshold time has elapsed then the marked information is flushed.
