摘要： At least one preamble is dedicated for interference probing. An aggressor access node (macro eNB) sends a command to a user equipment (UE) to transmit the dedicated preamble on a physical random access channel (PRACH). A victim access node (pico eNB) detects the transmitted preamble, and if this UE is the source of uplink interference to the victim access node it informs that to the macro access node which may then use interference coordination and interference cancellation to mitigate further uplink interference. In some embodiments the victim access node decides what is the transmit power for the UE to use for the dedicated preamble on the PRACH, and informs it to the macro access node which instructs the UE of the transmit power to use. In one example embodiment the victim access node calculates an offset from SRS/PUSCH transit power and informs the macro access node of the offset.
摘要翻译：至少一个前置码专用于干扰探测。攻击者接入节点（宏eNB）向用户设备（UE）发送命令以在物理随机接入信道（PRACH）上发送专用前同步码。受害者接入节点（微微eNB）检测所发送的前导码，并且如果该UE是受害接入节点的上行链路干扰源，则向宏接入节点通知该接入节点，然后可以使用干扰协调和干扰消除来减轻进一步的上行链路干扰。在一些实施例中，受害者接入节点决定UE在PRACH上为专用前同步码使用的发射功率是多少，并将其通知指示UE使用发射功率的宏接入节点。在一个示例实施例中，受害者接入节点计算从SRS / PUSCH传递功率的偏移量，并向宏接入节点通知偏移量。

摘要： A user equipment (UE) conducting machine-type communication (MTC) attempts to blindly decode a message it received using a pre-arranged and finite set of transport formats; and sends on an uplink radio resource feedback about the message, wherein the feedback is based on a result of the blind decoding. Each transport format of the pre-arranged set comprises a unique combination of modulation and coding scheme, physical resource block set;, and number of transmit repetitions. Prior to the message the pre-arranged set may be indicated to the UE in wireless signaling, or it may be specified in a radio standard. The set may be designated for downlink messages and a second set designated for uplink messages. Various embodiments are described for the uplink radio resource on which the feedback is sent, and conventional HARQ feedback is adapted for MTC in these teachings.

摘要： A user equipment UE sends in a first message on a random access channel at least one instance of a cyclic prefix CP and a configurable number of N instances of a sequence (N>1); then searches for a second message that replies to the first in a window defined by the first message and implicitly linked to the number N used in the first message. N can be configured by the UE based on its estimate of coverage improvement, and/or by the network and signaled via broadcast SIB/MIB. In one embodiment the first message has one CP and N sequences; in another the CP and sequence are placed in each of N transmission time intervals TTIs. Transmission of the first message begins in a TTI that is a function of a) a system frame number and the number N; and/or b) a time and frequency radio resource based on the number N.

摘要： A process, apparatus, and computer program product for enhancing coverage enhancement for network node signals targeted to machine type communication (MTC) devices such as automated wireless meters for water, electric and gas usage measurement. Two enhanced master information block (MIB) formats are defined. A first format contains all critical system information for common user equipment (UE) while the second format contains the critical system information plus the system information specific to MTC users. The second format provides sufficient system information necessary for MTC user equipment to initialize random access channel procedure. UE determines the eMIB format based on the detected primary synchronization signal/secondary synchronization signal (PSS/SSS) scheme and decodes the eMIB accordingly.
