摘要： A method and a system for scheduling requests generated for a plurality of mobile devices in a communication network (100) has been disclosed. The requests are generated for a transmission opportunity. The method includes computing a sort metric (302) for each request, based on an information update. A lead-time is then computed (304) with respect to a drop-dead time for each request, based on the sort metric for a time slice. The drop-dead time for a given time slice is the time before which scheduling has to be done so that data can be transmitted during the given time slice. Each request may be considered (306) for allocation in the time slice before the beginning of a next time slice, based on the lead-time.

摘要： A wireless communication system as described here employs control signaling for contention-based uplink access from user equipment devices to a base station. Contention-based access configuration is performed via physical downlink control channel signaling. Configuration data sent to the user equipment devices identifies multiple contention-based access zones, along with minimum power headroom values for each contention-based access zone. A probability factor may also be used to lower collision possibility by influencing whether the user equipment devices perform contention-based uplink access. An uplink grant message can be used to acknowledge contention-based transmission; contention resolution is achieved implicitly via the uplink grant.
摘要翻译：这里描述的无线通信系统采用从用户设备设备到基站的基于争用的上行链路接入的控制信令。基于竞争的接入配置通过物理下行链路控制信道信令进行。发送到用户设备设备的配置数据识别出基于争用的接入区域的多个基于争用的接入区域以及每个基于竞争的接入区域的最小功率余量值。也可以通过影响用户设备设备是否执行基于竞争的上行链路接入来降低碰撞可能性的概率因子。可以使用上行链路授权消息来确认基于竞争的传输; 通过上行链路授权隐含地实现争用解决。

摘要： A method, a system and an evolved nodeB (eNodeB) that enable user equipment (UE) to switch between carrier groups in a multi-carrier network. A carrier selection and switching (CSS) utility identifies a first and a second set of pre-configured groups of carrier frequencies that are subsequently assigned to a particular UE. The CSS utility notifies the UE of the assigned, pre-configured groups of carrier frequencies and provides the UE with system parameters associated with the first and second pre-configured groups of carrier frequencies. The CSS utility signals the UE to initiate communication via the first preconfigured group of carriers. Based on the occurrence of pre-established conditions, the CSS utility utilizes a switch signal to indicate via physical downlink control channel (PDCCH) to the UE (a) when to begin utilizing the second group of preconfigured carrier frequencies and (b) when to make subsequent switches between carrier groups.

摘要： A scheduler associated with a base station of a wireless communication network dynamically compensates for uplink bandwidth that has been re-assigned (stolen) by a mobile station (MS) to transmit a control message. The scheduler allocates a preset amount of bandwidth to the MS for data transmission. The scheduler detects bandwidth stealing activity and evaluates when bandwidth stealing is justified on he part of the MS. The scheduler provides additional bandwidth to appropriately compensate for the stolen bandwidth when bandwidth stealing is justified, in order to maintain the quality of service of the data traffic connection.

The method at a first node (102) of a plurality of nodes of the wireless communication network includes transmitting (304) a data frame to a second node (104) using a first transmit power level. The method further includes determining (306) whether an acknowledgement for the transmitted data frame is received from the second node. Further, the method includes determining (308) a cause of unsuccessful transmission when the acknowledgement is not received from the second node. Moreover, the method includes re-transmitting (310) the data frame to the second node using a second transmit power level when the cause of unsuccessful transmission is determined as a collision. Furthermore, the method includes setting (312) a transmit power level of the first node to a third transmit power level.

摘要： A method of allocating resources and signatures of a random access resource (RACH) (200) that includes dedicated (202) and non-dedicated (204) resources or sub-resources is disclosed. The network device determines if the dedicated resource is available for allocation. If the dedicated resource is available, the network device allocates the dedicated resource. If the dedicated resource is blocked, the network device allocates one of the non-dedicated resources. A message can be sent that indicates that allocated non-dedicated resource is being allocated as a dedicated resource.
