Definitions

  • the present disclosure relates to the field of communication technology, and in particular to a method, terminal and network device for receiving and sending information.
  • multi-point coordination is still an important technical means in the NR system.
  • network deployment with a large number of distributed access points + baseband centralized processing will be more conducive to providing a balanced user experience rate, and significantly reducing the delay and signaling overhead caused by handover .
  • frequency bands increase, from the perspective of ensuring network coverage, relatively dense deployment of access points is also required. In the high frequency band, as the integration of active antenna equipment increases, modular active antenna arrays will be more inclined.
  • each TRP Transmission and Reception Point, transceiver node
  • the antenna array of each TRP can be divided into several relatively independent antenna panels, so the shape and number of ports of the entire array can be flexibly adjusted according to deployment scenarios and business requirements.
  • the antenna panels or TRPs can also be connected by optical fibers for more flexible distributed deployment. In the millimeter wave band, as the wavelength decreases, the blocking effect generated by obstacles such as human bodies or vehicles will become more significant. In this case, from the perspective of ensuring the robustness of the link connection, the cooperation between multiple TRPs or panels can also be used to transmit/receive multiple beams from multiple angles, thereby reducing the blocking effect. Negative Effects.
  • the coordinated multipoint transmission technology can be divided into two types: coherent and non-coherent transmission.
  • coherent transmission each data layer will be mapped onto multiple TRPs/panels through a weighted vector.
  • non-coherent transmission each data stream is only mapped to part of the TRP/panel.
  • Coherent transmission has higher requirements for the synchronization between transmission points and the transmission capacity of the backhaul link, so it is more sensitive to many non-ideal factors in actual deployment conditions. Relatively speaking, non-coherent transmission is less affected by the above factors, so it is a key consideration for multipoint transmission technology.
  • NC-JT transmission can use a single PDCCH (physical downlink control channel) to schedule a single PDSCH (physical downlink shared channel) (single-PDCCH), or multiple PDCCHs to schedule the corresponding PDSCH (multi-PDCCH) .
  • PDCCH physical downlink control channel
  • PDSCH physical downlink shared channel
  • multi-PDCCH multiple PDCCHs
  • a more ideal backhaul link is required to exchange CSI and control information.
  • a new codeword mapping method may be required. For example, consider using 2 codewords below 4 layers, and use independent MCS (modulation and coding scheme) to match the channel conditions of different transmission points/panels. You can even consider using a non-equal mapping method on the two codewords.
  • DM-RS modulation and demodulation reference signal
  • QCL quadrature co-location
  • TCI transmission control Information
  • the transmission of the two PDSCHs and the corresponding PDCCH is relatively independent, this mode is not sensitive to non-ideal factors such as the delay of the backhaul link.
  • each PDSCH can correspond to different transmission points/panels, independent transmission of multiple PDSCHs can avoid the complexity of codeword mapping, DMRS port grouping, TCI design, and DMRS port indication. It should be noted that although it is possible to consider using a completely flexible scheduling method among multiple PDSCHs, it is also necessary to consider quasi-static coordination between transmission points/panels to avoid interference between PDSCH or DM-RS ports.
  • a certain coordination mechanism and scheduling restrictions can be used to avoid partial overlap between PDSCHs to ensure the accuracy of receiver interference estimation and link adaptation performance.
  • the corresponding uplink and downlink control channel design and HARQ (Hybrid Automatic Repeat) scheme design are also content to be studied.
  • multi-point collaboration technology is of great significance for improving the reliability of URLLC (ultra-reliable low-latency communication) service transmission.
  • URLLC ultra-reliable low-latency communication
  • the cooperative transmission of multiple transmission points/panels can be used to reduce the probability of signal being blocked.
  • multiple transmission points/panels can be repeated or diversified to improve transmission reliability.

本申请主张在2019年4月30日在中国提交的中国专利申请号No.201910363888.8的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种信息的接收、发送方法、终端及网络设备。
背景技术
为了改善小区边缘的覆盖，在服务区内提供更为均衡的服务质量，多点协作在NR系统中仍然是一种重要的技术手段。从网络形态角度考虑，以大量的分布式接入点+基带集中处理的方式进行网络部署将更加有利于提供均衡的用户体验速率，并且显著的降低越区切换带来的时延和信令开销。随着频段的升高，从保证网络覆盖的角度出发，也需要相对密集的接入点部署。而在高频段，随着有源天线设备集成度的提高，将更加倾向于采用模块化的有源天线阵列。每个TRP(Transmission and Reception Point，收发节点)的天线阵可以被分为若干相对独立的天线面板，因此整个阵面的形态和端口数都可以随部署场景与业务需求进行灵活的调整。而天线面板或TRP之间也可以由光纤连接，进行更为灵活的分布式部署。在毫米波波段，随着波长的减小，人体或车辆等障碍物所产生的阻挡效应将更为显著。这种情况下，从保障链路连接鲁棒性的角度出发，也可以利用多个TRP或面板之间的协作，从多个角度的多个波束进行传输/接收，从而降低阻挡效应带来的不利影响。
根据发送信号流到多个TRP/面板上的映射关系，多点协作传输技术可以分为相干和非相干传输两种。其中，相干传输时，每个数据层会通过加权向量映射到多个TRP/面板之上。而非相干传输时，每个数据流只映射到部分的TRP/面板上。相干传输对于传输点之间的同步以及回程链路的传输能力有着更高的要求，因而对现实部署条件中的很多非理想因素较为敏感。相对而言， 非相干传输受上述因素的影响较小，因此是多点传输技术的重点考虑方案。
NC-JT传输可以采用单PDCCH(物理下行控制信道)调度单个PDSCH(物理下行共享信道)的方式(single-PDCCH)，也可以采用多个PDCCH，各自调度对应的PDSCH的方式(multi-PDCCH)。
对于single-PDCCH方式，由于传输点之间协作更紧密，需要更为理想的回传链路交互CSI和控制信息。考虑到传输点或面板之间信道条件的差异，可能需要新的码字映射方式。例如，可以考虑在4层以下使用2个码字，用独立的MCS(调制编码方案)分别匹配不同传输点/面板的信道条件。甚至可以考虑在两个码字上使用非对等的映射方式。针对不同的传输点/面板发送的信号，还需要根据QCL(准共址)关系对DM-RS(调制解调参考信号)端口进行分组，指示不同的QCL信息，并设计相应的TCI(传输控制信息)结构和控制信令。为了支持以上增强，可能还需要对DCI(下行控制信息)中的DM-RS分配方式进行重新设计。除此之外，也需要考虑对CSI上报方式的改进，以支持单点传输与协作传输之间的切换。
对于multi-PDCCH方式，由于两个PDSCH与相应的PDCCH的传输相对独立，因此这种方式对回传链路的时延等非理想因素不敏感。同时，由于每个PDSCH可对应于不同的传输点/面板，多个PDSCH的独立传输可以避免码字映射、DMRS端口分组、TCI设计、DMRS端口指示方面的复杂度。需要说明的是，尽管可以考虑在多个PDSCH之间使用完全灵活的调度方式，但是也需要考虑通过传输点/面板之间准静态的协调，以避免PDSCH或DM-RS端口之间的干扰。或者可以通过一定的协调机制及调度限制，避免PDSCH之间部分重叠的情况，以保证接收机干扰估计的准确性以及链路自适应性能。多PDSCH传输时，相应的上下行控制信道设计及HARQ(混合自动重传)方案设计也是需要研究的内容。
除了eMBB业务之外，多点协作技术对于提升URLLC(超可靠低时延通信)业务传输的可靠性具有很重要的意义。例如，在高频段，阻挡效应可能造成通信的暂时中断。这种情况下，可以通过多个传输点/面板的协作发送，降低信号被阻挡的概率。此外，还可以通过多个传输点/面板的重复或分集发送，提高传输的可靠性。
相关技术存在的问题是：无法确定DMRS端口的TCI状态与CDM组的对应关系。
