Abstract: The transmission and reception group delay in a front end structure of a mobile device may be determined using closed loop calibration. The closed loop may be a near field radiated closed loop between pairs of antennas in an antenna array of the mobile device. The delay based on time of transmission and time of reception may be measured for a plurality of pairs of antennas, from which the transmit and receive group delay within a single path may be determined. The propagation delay of the signal between antennas may be included in the group delay calibration for increased accuracy. In another implementation, a conducted closed loop in the transceiver or in a radio frequency switching network may be used to calibrate the group delay. Precharacterization of the delay caused by components between the closed loop and antennas may be included in the group delay calibration for increased accuracy.

Abstract: Aspects relate to provision of a control message, such as an extension data section, that includes an indication of the repeat of highest priority data sections. The control message may be generated in a distributed unit (DU) and conveyed to a radio unit (RU) via a fronthaul link. The control message may include either a flag or bits in a field of an extension data section allowing a RU to determine repeat of the highest priority data section based on reception of the flag or processing of the bit value in the field. Additionally, the indication of repetition of the highest priority section may be based on a section identifier transmitted by a DU, wherein an RU receiving the section identifier may determine repeat of the highest priority data section by tracking the received section identifier.

Abstract: Embodiments disclosed herein address the need in the art for an efficient multi-symbol deinterleaver. In one aspect, a plurality of memory banks are deployed to receive and simultaneously store a plurality of values, such as soft decision values determined from a modulation constellation, in accordance with a storing pattern. In another aspect, the storing pattern comprises a plurality of cycles, a selected subset of the plurality of memory banks and an address offset for use in determining the address for storing into the respective memory banks indicated for each cycle. In yet another aspect, the stored values may be accessed in order with a sequentially increasing index, such as an address. Various other aspects are also presented. These aspects have the benefit of allowing multiple symbol values to be deinterleaved in an efficient manner, thus meeting computation time constraints, and conserving power.
Abstract translation: 本文公开的实施例解决了本领域对于有效的多符号解交织器的需要。 在一个方面，多个存储体被部署以根据存储模式来接收并同时存储多个值，诸如从调制星座确定的软判决值。 在另一方面，存储模式包括多个周期，多个存储体的选定子集和用于确定用于存储到为每个周期指示的相应存储体中的地址的地址偏移。 在另一方面，可以按顺序增加的索引（诸如地址）按顺序访问所存储的值。 还提出了各种其他方面。 这些方面具有允许以有效的方式解码多个符号值的好处，从而满足计算时间限制并节省功率。
