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.
摘要翻译：提供了一种支持In-Device共存干扰避免的隐式信令的方法。 UE向eNB发送IDC干扰指示。该指示表示由于共存干扰问题，服务频率变得不可用。该指示没有明确地指示不可用的服务频率的频率索引或频率位置。 eNB将服务频率以隐含的方式确定为不可用。 eNB还基于接收的IDC指示确定隐含的不可用频率区域。隐含的不可用频率区域在服务频率和ISM频带之间。在一个有利的方面，eNB配置UE的条件，使得除非满足条件，否则UE不会发送IDC干扰指示。

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： 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.

摘要： A method of dynamic resource transaction in wireless OFDMA systems is proposed. In macro-femto overlay network architecture, network and traffic condition varies dynamically. Dynamic resource transaction is a powerful mechanism to achieve effective interference mitigation and flexible radio resource management to enhance resource utilization as well as to improve link performance. Dynamic resource transaction can be performed by signaling or message exchange through backhaul network or air-interface connections. The signal or message through backhaul network can be directly exchanged among multiple base stations or be routed through a centralized self-organizing network (SON) server. In one embodiment, dynamic resource transaction is used to achieve adaptive reservation region configuration, a solution to avoid interference and frequent handover for high-speed mobile stations.

摘要： A unified synchronous ranging channel is provided. The unified synchronous ranging channel has a ranging cyclic prefix length that is the same as a cyclic prefix length of a data channel. The unified synchronous ranging channel is used for one of initial ranging, handover ranging, and periodic ranging between a mobile station and a femto base station. In one embodiment, the synchronous ranging channel spans over a two-dimensional radio resource region having a first number of subcarriers along frequency domain, a second number of OFDM symbols along time domain, and a third number of time-domain repetition. At the transmit side, a ranging code sequence is generated by applying a fixed time-domain cyclic shift per OFDM symbol to a root sequence. At the receive side, the ranging code sequence is decoded by using a summation module, a likelihood-combining module, and a modified peak test module that normalizes a peak value.

摘要： A method of failure event report correlation is proposed. A UE detects a failure event in a first cell served by a first base station, and the UE is assigned with a previous C-RNTI. The failure event may include a radio link failure, a handover failure, or a RACH failure. The UE then performs an RRC establishment procedure with a second base, and the UE is assigned with a new C-RNTI. After the RRC establishment, the UE transmits a failure event report along with the correlation information to the second base station. The second base station then forwards the failure event report and the previous C-RNTI to the first base station. The first base station can correlate the failure event report with the previous failure event based on the previous C-RNTI to avoid double bookkeeping and improve MRO decision for SON.
摘要翻译：提出了一种故障事件报告相关的方法。 UE检测由第一基站服务的第一小区中的故障事件，并且向UE分配先前的C-RNTI。故障事件可能包括无线电链路故障，切换故障或RACH故障。然后，UE执行具有第二基站的RRC建立过程，并且向UE分配新的C-RNTI。在RRC建立之后，UE将故障事件报告与相关信息一起发送到第二基站。第二基站然后将故障事件报告和先前的C-RNTI转发到第一基站。第一个基站可以根据先前的C-RNTI将故障事件报告与先前的故障事件相关联，以避免双重记录，并改善SON的MRO决策。

摘要： Various measurement configurations and s-Measure mechanism in multi-carrier OFDMA systems are provided. In one embodiment, a user equipment (UE) measures a first reference signal received power (RSRP) level in a primary serving cell (Pcell) over a primary component carrier (PCC). The UE also measures a second RSRP level in a secondary serving cell (Scell) over a secondary component carrier (SCC). The UE compares the first RSRP level with a first s-Measure value and compares the second RSRP level with a second s-Measure value. The UE then enables s-Measure mechanism and stops measuring neighbor cells over the PCC if the first RSRP level is higher than the first s-Measure value. The UE also enables s-Measure mechanism and stops measuring neighbor cells over the SCC if the second RSRP level is higher than the second s-Measure value. By having independent s-Measure mechanism and independent s-Measure value, maximum flexibility is achieved.
摘要翻译：提供了多载波OFDMA系统中的各种测量配置和s-Measure机制。在一个实施例中，用户设备（UE）通过主分量载波（PCC）测量主服务小区（Pcell）中的第一参考信号接收功率（RSRP）电平。 UE还通过辅助分量载波（SCC）测量辅助服务小区（Scell）中的第二RSRP级别。 UE将第一RSRP级别与第一s-Measure值进行比较，并将第二RSRP级别与第二s-Measure值进行比较。然后，如果第一RSRP电平高于第一s-Measure值，则UE然后启用s测量机制并停止通过PCC测量相邻小区。如果第二RSRP级别高于第二s-Measure值，则UE还启用s-Measure机制并停止在SCC上测量相邻小区。通过独立的s-Measure机制和独立的s-Measure值，实现了最大的灵活性。
