Abstract: Methods and apparatus are provided for Msg3 collision resolutions. In one embodiment, the UE obtains a set of DMRS seeds and randomly selecting one to generate a DMRS sequence for the Msg3. The set of DMRS seeds is either generated based on a received cell-specific parameter or are received from the network. In another embodiment, the eNB, upon detecting the collision in Msg3, indicates a lowered MCS level for the Msg3 transmission in the RAR after the preamble detection. In another embodiment, the early termination of Msg3 transmission is used upon determining the collision of Msg3. In one embodiment, the eNB responds an ACK to a failed Msg3 to suspend the re-transmission of the Msg3. In another embodiment, the eNB sends a flag to cancel the mac-ContentionResolutionTimer and terminate the Msg3 transmission. The termination indication is either embedded in the acknowledgement signaling or sent through PDCCH signaling.

Abstract: Methods for rate matching with soft buffer size setting at the transmitter and soft channel bits storage at the receiver for superposition coding are proposed. In the superposition coding scheme, a transport block intended to one UE needs to be decoded by another UE's receiver. However, the soft buffer sizes per code block of the two receivers may not be the same since the size depends on the UE category. The base station can signal the soft buffer size used at the transmitter for rate matching to the UEs for superposition decoding. A UE stores information bits associated with an interfering signal in its soft buffers in accordance with the soft buffer size used at the transmitter for rate matching. As a result, the UE can decode and subtract the interfering signal from the desired signal for superposition coding.
Abstract translation: 提出了在发射机处的软缓冲器大小设置的速率匹配方法和用于叠加编码的接收机处的软信道比特存储的方法。 在叠加编码方案中，用于一个UE的传输块需要被另一个UE的接收机解码。 然而，两个接收机的每个码块的软缓冲器大小可能不相同，因为该大小取决于UE类别。 基站可以将发送器使用的软缓冲区大小信号发送给UE进行叠加解码。 UE根据用于速率匹配的发送器使用的软缓冲器大小，将与干扰信号相关联的信息位存储在其软缓冲器中。 结果，UE可以从用于叠加编码的期望信号中解码和减去干扰信号。

Abstract: When the codeword level interference cancellation (CW-IC) is used at the receiver in conjunction with the superposition coding scheme at the transmitter, in order to guarantee the success of signal reception, restrictions of scheduling decisions in resource allocation of superposed transport blocks may occur. A method to mitigate the scheduling restrictions is proposed. For a low-geometry UE in NOMA operation, one sub-band is used as the basic scheduling unit. As a result, data in resource blocks scheduled for NOMA operation and data in resource blocks scheduled for other non-NOMA operation correspond to different transport blocks. Therefore, a high-geometric UE only needs to decode the data scheduled for NOMA. The base station does not need to impose additional scheduling restrictions and signaling overhead.
Abstract translation: 当在发射机处结合重叠编码方案在接收机处使用码字电平干扰消除（CW-IC）时，为了保证信号接收成功，可能发生重叠传输块的资源分配中的调度决策的限制 。 提出了一种减轻调度限制的方法。 对于NOMA操作中的低几何UE，使用一个子带作为基本调度单元。 结果，为NOMA操作调度的资源块中的数据和为其他非NOMA操作调度的资源块中的数据对应于不同的传输块。 因此，高几何UE仅需要解码为NOMA调度的数据。 基站不需要强加额外的调度限制和信令开销。

Abstract: A method of DRX operation enhancement in adaptive TDD systems is proposed. A UE configures and enters DRX operation in an LTE/LTE-A mobile communication network. The UE obtains adaptive TDD configuration information from a base station. The adaptive TDD configuration information comprises an actual TDD configuration and a reference TDD configuration. The UE performs DRX timer counting and HARQ timer counting based on the reference TDD configuration. The UE also synchronizes DRX status with the base station. With the reference TDD configuration, it can avoid the potential misunderstanding between eNB and UE regarding DRX and HARQ RTT timing when TDD configuration changes.

A UE establishes a radio resource control (RRC) connection with a base station in a mobile communication network. The UE obtains adaptive time division duplex (TDD) configuration information from the base station, wherein the adaptive TDD configuration information comprises an actual TDD configuration and/or a reference TDD configuration.

Abstract: A method for coordinating transmissions between different communications apparatuses in a communications system. The method obtains a sub-frame indicator carried in a first control signal transmitted in a control region of a first sub-frame received from an evolved node B (eNB), wherein the sub-frame indicator indicates resource allocation of one or more sub-frame following the first sub-frame. The method then determines whether a second sub-frame following the first sub-frame and received from the eNB is an almost blank sub-frame according to the sub-frame indicator. When the second sub-frame is not the almost blank sub-frame, obtaining information regarding a start position of a data region of the second sub-frame from a second control signal transmitted in a control region of the second sub-frame.

Abstract: A method of UE transmit power adjustment based on TPC command in adaptive TDD systems is proposed. A UE obtains TDD configuration information from a base station in an adaptive TDD system. The UE also obtains an HARQ reference configuration from the base station. The UE then receives a transmit power control (TPC) command in one or more previous subframes. The UE performs power adjustment in a subsequent subframe based on the TPC command. The location of the previous subframes is determined based on the HARQ reference configuration. In one embodiment, an UL HARQ reference configuration is applied for PUSCH power control. In another embodiment, a DL HARQ reference configuration is applied for PUCCH power control.

Abstract: A method of network-based positioning using sounding reference signal (SRS) is proposed. An eNodeB configures a number of parameters of a periodic SRS transmission for a user equipment (UE). The eNodeB then transmits SRS configuration data for SRS measurements performed by a location measurement unit (LMU). The SRS configuration data includes cell-specific SRS bandwidth configuration and UE-specific SRS bandwidth configuration. The SRS configuration data may further include a number of antenna ports for SRS transmission, SRS frequency hopping bandwidth configuration, information on whether SRS sequence-group hopping is enabled, and Δss when SRS sequence hopping is enabled. Upon receiving the SRS configuration data, the LMU is able to perform timing measurements over the received SRS signals from the UE. In one embodiment, the LMU detects SRS dropping to avoid performance degradation of the network-based positioning.
