Abstract: Methods, systems, and devices for transmission and reception of SPS communications are disclosed herein. User equipment (UE) is configured to receive, in a first subframe, a physical downlink control channel or enhanced physical downlink control channel (PDCCH/EPDCCH) corresponding to semi-persistent scheduling (SPS) activation. The PDCCH/EPDCCH conveys a value of nSCID. The UE configures, based on the SPS activation, a downlink (DL) assignment in a second subframe for receiving an SPS physical downlink shared channel (PDSCH) without a corresponding PDCCH/EPDCCH. The UE determines a reference signal sequence corresponding to the SPS PDSCH using nSCID derived from the PDCCH/EPDCCH corresponding to the associated SPS activation. The UE receives the SPS PDSCH in a second subframe. The UE processes the SPS PDSCH based on the reference signal sequence for the SPS PDSCH in the second subframe using the nSCID derived from the PDCCH/EPDCCH corresponding to the associated SPS activation. The UE is configured for transmission mode 10 (TM10).

Abstract: Embodiments of the present disclosure include methods, apparatuses, and instructions for receiving at a user equipment (UE) of a third generation partnership project (3GPP) network an offset value selected from a plurality of offset values in downlink control information. The UE also receives one or more enhanced control channel elements (eCCEs) of an enhanced physical downlink control channel (ePDCCH). The UE may then determine an allocation of an uplink resource for a transmission on a physical uplink control channel (PUCCH) based at least in part on the index of a first eCCE and the offset value.

Abstract: Methods for contention-based transmission with contention-free feedback for reduced latency in LTE Advanced networks and an enhanced PUCCH are generally disclosed herein. User equipment (UE) may transmit a contention sequence on a physical uplink control channel (PUCCH) to an enhanced-Node B (eNB) and may concurrently transmit data requesting uplink resources on a physical uplink shared channel (PUSCH) to the eNB. The contention sequence is transmitted on the PUCCH in accordance with a format that is assigned by the eNB. The contention sequence is either randomly selected by the UE or assigned by the eNB. When the contention sequence and data are not successfully received by the eNB, the UE may fall back to a more conventional random access channel (RACH) procedure for uplink resource allocation.

Abstract translation: 通常在此公开了用于LTE LTE网络和增强型PUCCH的减少等待时间的无争用反馈的基于争用的传输方法。 用户设备（UE）可以将物理上行链路控制信道（PUCCH）上的竞争序列发送到增强型节点B（eNB），并且可以在物理上行链路共享信道（PUSCH）上向eNB发送请求上行链路资源的数据。 根据由eNB分配的格式，在PUCCH上发送争用序列。 竞争序列由UE随机选择或由eNB分配。 当eNB没有成功地接收到争用序列和数据时，UE可以回退到用于上行链路资源分配的更常规的随机接入信道（RACH）过程。
