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： 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： Systems and Methods for supporting carrier aggregation with different TDD configurations are proposed. In a first novel aspect, corresponding apparatus structure is described. In a second novel aspect, aggregation constraint is discussed. In a third novel aspect, transceiving mechanisms over multiple component carriers in DL/UL overlapped subframes are proposed. For simultaneous DL/UL transceiving, band combination indication methods are proposed, and HARQ feedback mechanisms are proposed. For non-simultaneous DL/UL transceiving, transceiving configuration methods are proposed, and the same HARQ feedback mechanisms are proposed. In a fourth novel aspect, CQI/RLM/RRM measurement mechanisms are proposed. In a fifth novel aspect, UE capability signaling mechanisms are proposed. The objective is to support flexible aggregation, to enhance DL data throughout, and to improve UL transmit power efficiency.

摘要： A method of implicit signaling to support In-Device coexistence interference avoidance is provided. A UE sends an IDC interference indication to an eNB. The indication indicates that a serving frequency becomes unusable due to a coexistence interference problem. The indication does not explicitly indicate a frequency index or a frequency location of the unusable serving frequency. The eNB determines the serving frequency as unusable in an implicit manner. The eNB also determines an implied unusable frequency region based on the received IDC indication. The implied unusable frequency region is between the serving frequency and the ISM band. In one advantageous aspect, the eNB configures a condition for the UE, such that the UE is refrained from sending IDC interference indications unless the condition is satisfied.

摘要： A method of providing Local IP Access (LIPA) indication is proposed. In one novel aspect, an enhanced cell selection method is proposed using LIPA capability information. Based on LIPA capability related information, a UE is able to prioritize LIPA-capable cells and establish a corresponding packet data network (PDN) connection accordingly. In one embodiment, LIPA information is informed to the UE via Non Access Stratum (NAS) signaling. The UE stores LIPA capability information when receiving a NAS message from a mobility management entity (MME). Later on, when the UE performs cell selection or reselection in idle mode, the UE can use the stored LIPA capability information to prioritize LIPA-capable cells.

摘要翻译： 提出了一种提供本地IP访问（LIPA）指示的方法。 在一个新颖的方面，提出了使用LIPA能力信息的增强小区选择方法。 基于LIPA能力相关信息，UE能够优先考虑具有LIPA能力的小区并相应地建立对应的分组数据网络（PDN）连接。 在一个实施例中，通过非接入层（NAS）信令向UE通知LIPA信息。 当从移动性管理实体（MME）接收到NAS消息时，UE存储LIPA能力信息。 稍后，当UE在空闲模式下执行小区选择或重选时，UE可以使用存储的LIPA能力信息来优先考虑具有LIPA能力的小区。

摘要： A channel interleaver comprises a novel constellation-based permutation module. The channel interleaver first receives a plurality of sets of encoded bits generated from an FEC encoder. The encoded bits are distributed into multiple subblocks and each subblock comprises a plurality of adjacent bits. A subblock interleaver interleaves each subblock and outputs a plurality of interleaved bits. The constellation-based permutation module rearranges the interleaved bits and outputs a plurality of rearranged bits. The rearranged bits are supplied to a symbol mapper such that a plurality of consecutively encoded bits in the same set of the encoded bits generated from the FEC encoder is prevented to be mapped onto the same level of bit reliability of a modulation symbol. In addition, the plurality of adjacent bits of each subblock is also prevented to be mapped onto the same level of bit reliability to achieve constellation diversity and to improve decoding performance.
