Abstract: A method and apparatus can be configured to determine an uplink-downlink configuration. The method also transmits an indication of the uplink-downlink configuration. The transmitting the indication of the uplink-downlink configuration includes using physical layer signaling. The transmitting the indication of the uplink-downlink configuration also includes reusing an existing physical layer channel. The transmitting the indication of the uplink-downlink configuration is performed without extending physical layer associations

Abstract: A method and apparatus may include receiving, by a machine type communication user equipment, parameters for frequency hopping in downlink or uplink. The parameters comprise an “X,” ‘Y,” and “Z” parameters, “X” corresponds to a duration for which the same physical resource blocks are used for transmission. ‘Y” corresponds to a frequency hopping period, and “Z” corresponds to a frequency hopping pattern indication. The method may also include performing frequency hopping in accordance with the parameters.

Abstract: Various communication systems may benefit from techniques for handling inter-band carrier aggregation (CA). For example, systems of the third generation partnership project (3GPP) long term evolution (LTE) advanced (LTE-A) may benefit from a uplink (UL) downlink (DL) configuration zero handling, particularly in cases where there is no physical hybrid automatic repeat request (HARQ) indicator channel (PHICH). For example, certain embodiments may be applicable to inter-band CA having different UL/DL configuration in use. A method can include triggering in a downlink subframe a first physical uplink shared channel transmission in a first hybrid automatic repeat request process. The method can also include triggering in the downlink subframe a second physical uplink shared channel transmission in a second hybrid automatic repeat request process. The secondary cell can be configured with time division duplex uplink/downlink configuration number zero. The triggerings can be performed by means of a single uplink grant but without a hybrid automatic repeat request indicator.

Abstract translation: 各种通信系统可能受益于处理带内载波聚合（CA）的技术。 例如，第三代合作伙伴计划（3GPP）长期演进（LTE）高级（LTE-A）的系统可以受益于上行链路（UL）下行链路（DL）配置零处理，特别是在没有物理混合的情况下 自动重发请求（HARQ）指示符信道（PHICH）。 例如，某些实施例可以适用于在使用中具有不同UL / DL配置的带间CA。 一种方法可以包括在第一混合自动重复请求过程中在下行链路子帧中触发第一物理上行链路共享信道传输。 该方法还可以包括在第二混合自动重传请求过程中在下行链路子帧中触发第二物理上行链路共享信道传输。 辅助小区可以配置有时分双工上行链路/下行链路配置号零。 触发可以通过单个上行链路授权执行，但没有混合自动重发请求指示符。

Abstract: Systems, methods, apparatuses, and computer program products of PRACH selection and random access response (RAR) detection are provided. One method includes specifying, by a network node, a starting point for preamble repetition having a repetition level such that all user equipment (UEs) of the same repetition level start the preamble repetition on a same physical random access channel (PRACH) resource, determining when a series of the preamble repetition is over, and transmitting a random access response (RAR) when the repetition series is finished.

Abstract: Systems, methods, apparatuses, and computer program products for power control enhancement are provided. One method includes retrieving, by an eNB, subframe type information in connection with uplink (UL)/downlink (DL) configuration. The method then includes simultaneously indicating, using physical layer signaling, at least one of the subframe type information and/or corresponding power control parameter set to a user equipment. In one example, the subframe type information and/or the corresponding power control parameter set may be indicated in reused bits of a transmit power command (TPC).
