摘要： Different sequence resources can be allocated to a mobile device where the mobile device can exclusively uses the sequence resource with regard to a base station during a communication session. However, if another mobile device using another base station is assigned a matching sequence resource, then there can be interference if the mobile devices are relatively close enough together. Therefore, randomization of the sequence resources can take place—moreover, a cyclic shift result can be employed in sequence resource allocation to attempt to minimize interference.

摘要： User equipment (UE) associated with synchronous networks operate in a synchronous mode while UEs associated with asynchronous networks operate in an asynchronous mode. When operating in a synchronous mode, a UE can significantly improve performance of synchronization signal detection, data decoding, and tracking loop management by using the interference cancellation (IC) techniques that are not available in an asynchronous mode of operation. Obtaining synchronization indicators and determining the synchronization status of the current network by UE is disclosed. The determination may be based on the synchronization indicator, whether detected through signal detection, signal measurements, signal analysis, or the like.

摘要： Techniques are provided for single carrier optimization. For example, there is provided a method that involves, in a subframe of a radio spectrum, allocating a first set of resource elements (REs) for multimedia broadcast over a single frequency network (MBSFN) transmissions, each symbol corresponding to each RE of the first set having a first cyclic prefix (CP) type. The method may involve allocating a second set of REs for unicast transmissions, each symbol corresponding to each RE of second set having a second CP type. The method may involve determining whether the first CP type and the second CP type are the same. The method may involve, in response to the first CP type and the second CP type being the same, combining the MBSFN transmissions and the unicast transmissions in the subframe according to the allocated first and second sets of REs.

摘要： Providing for improved error control signaling in wireless communications is disclosed herein. By way of example, multiple transmissions can be conducted for a HARQ process prior to a scheduled feedback signal on the HARQ process, causing a receiving device to combine the multiple transmissions, rather than treat them as separate transmissions. In this manner, multiple transmissions can be employed to increase overall receive energy, without violating maximum transmit power constraints in a wireless communication. Further, these multiple transmissions can be configured based on prevailing signal strength at the receiving device, or based on processing capabilities of the receiving device, providing flexible protocols that can accommodate advanced as well as legacy UEs in wide range of wireless conditions.
摘要翻译：本文公开了在无线通信中提供改进的差错控制信令。作为示例，可以在HARQ过程之前的调度的反馈信号之前对HARQ进程进行多个传输，使得接收设备组合多个传输，而不是将其作为单独的传输。以这种方式，可以采用多个传输来增加总体接收能量，而不违反无线通信中的最大发射功率约束。此外，可以基于接收设备处的主要信号强度或基于接收设备的处理能力来配置这些多个传输，从而提供可在宽范围的无线条件下适应高级以及传统UE的灵活协议。

摘要： Carrier aggregation to enhance Evolved Multimedia Broadcast Multicast Service (eMBMS) includes transmitting unicast signaling for a unicast service on an anchor carrier to mobile entities, transmitting eMBMS signaling on a second carrier different from the anchor carrier to the mobile entities for use with the unicast signaling, and various techniques for practical application of carrier aggregation for eMBMS enhancement. In addition, allocating subframes used for MBMS on a Single Frequency Network (MBSFN) includes allocating at least a portion of one or more subframes otherwise reserved for unicast subframes on a mixed carrier to provide an increased allocation of subframes carrying MBSFN information, transmitting MBSFN signals on the increased allocation of subframes, and more detailed aspects.

摘要： Techniques for performing interference and power control in a wireless communication system are described. An asymmetric power control scheme adjusts the transmit power of a user equipment (UE) in an asymmetric manner, e.g., with different up and down step sizes. In one design, a parameter value may be determined based on received SINR of at least one Node B. Up and down steps may be determined based on the parameter value and may have different sizes. At least one overloading indicator from at least one neighbor Node B may be obtained. The transmit power of the UE may be adjusted based on the up and down steps and the at least one overloading indicator. For example, the transmit power may be increased by the up step if an overloading indicator from the strongest neighbor Node B is not received and may be decreased by the down step otherwise.

摘要： Systems and methods for setting parameters for transmissions of data from a mobile station to a base station in a wireless communications system. One embodiment comprises a method including a network detecting a mobile station entering or leaving soft handoff and responsively modifying a transmission parameter. The transmission parameter may comprise frame duration, wherein if the mobile station enters soft handoff, the frame duration is set to a larger value and if the mobile station leaves soft handoff, the frame duration is set to a smaller value. The network may determine whether the mobile station should enter or leave soft handoff based upon PSMMs and may send handoff direction messages (HDMs) to the mobile station, thereby causing the mobile station to enter or leave soft handoff and to set the transmission parameter accordingly.
