摘要： Various methods for wireless communication in a device with co-existed/co-located radios are provided. Multiple communication radio transceivers are co-existed/co-located in a user equipment (UE) having in-device coexistence (IDC) capability, which may result in IDC interference. For example, the UE is equipped with both LTE radio and some ISM band applications such as WiFi and Bluetooth modules. In a first method, the network identifies IDC capability by UE identification (e.g., UE ID). In a second method, the UE intentionally performs cell selection or reselection to cells in non-ISM frequency bands. In a third method, the UE signals the existence of ISM band applications via capability negotiation. In a fourth method, the UE signals the activation of ISM band applications by signaling messages (e.g., RRC message or MAC CE). Under the various methods, the UE and its serving eNB can apply FDM or TDM solutions to mitigate the IDC interference.

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： 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.
