Description

A kind of user equipment that be used to wirelessly communicate, the method and apparatus in base station

Technical field

This application involves the transmission methods and device in wireless communication system, more particularly, in narrowband Internet of things system The method and apparatus of transmission.

Background technique

Traditional third generation cooperative partner program (3GPP -3rd Generation Partner Project) long term evolution In (LTE-Long Term Evolution) system, time division duplex (TDD-Time Division Duplex) system is defined Frame structure, the subframes of some distribution transmits uplink (Uplink, UL) link for uplink, other subframes are used for downlink The transmission of (Downlink, DL) link, the switching between downlink and uplink link occur in special subframe, which again may be used To be divided into, DwPTS (Downlink Pilot Time Slot, descending pilot frequency time slot), (Gurad Priod is protected a GP Shield interval) and a UpPTS (Uplink Pilot Time Slot, uplink pilot time slot).Although DwPTS is relative to conventional son The length of frame is shorter, but it can be used as a downlink subframe still substantially to carry out information transmission.

Narrowband Internet of Things (NB-IoT-Narrow Band Internet of Things) is that one of the field IoT is emerging Technology, NB-IoT are implemented in cellular network, only consume the bandwidth of about 180KHz, can be deployed directly into traditional network, with drop Small configuration cost realizes smooth upgrade.NB-IoT is at first in 3GPP (3rd Generation Partner Project, third For partner program) it introduces in Rel-13, the NB-IoT system of Rel-13 is enhanced in 3GPP Rel-14. The more functions of non-anchor Physical Resource Block are just to confer in Rel-14 in terms of critically important one enhancing, for example support paging channel Transmission, support the transmission etc. of random access channel, while introducing the function of positioning and multicast.It is right in 3GPP Rel-15 NB-IoT is further enhanced, including reduces power consumption, is enhanced the precision of measurement, is introduced special scheduling request etc..Especially , the support to TDD can be also introduced in Rel-15 version.

Summary of the invention

When carrying out NB-IOT communication under TDD scene, a problem to be solved is whether for DwPTS to be used for downlink biography It is defeated.In view of spectrum efficiency and NB-IOT are for the insensitivity of delay, it is clear that will be increased using DwPTS for downlink transfer The spectrum efficiency and handling capacity of adding system.However, when DwPTS is used for NPDCCH (Narrowband Physical Downlink Control Channel, narrowband Physical Downlink Control Channel) transmission when, how by NCCE (Narrowband Control Channel Element, narrowband control channel unit) it is mapped in RE included by a DwPTS and will be firstly the need of begging for By the problem of.In response to this problem, a simple solution is exactly to continue to use FDD (FDD-Frequency Division Duplex mapping rule), i.e., by an occupied RE of NB-IOT downlink subframe (Resource Element, resource particle) It is divided into two parts according to lower 6 subcarriers of frequency domain position and higher 6 subcarriers of frequency domain position, wherein any a part It is the occupied RE set of a NCCE, i.e. a NB-IOT downlink subframe includes two NCCE；And in a RE set, NCCE is mapped according to the sequence of the first time domain of frequency domain second.Above-mentioned FDD traditional scheme is advantageous in that, simplifies NCCE to RE Mapping rule, and the NCCE in different subframes can merge reception to realize merging gain.However, in DwPTS If the mode of FDD is continued to use in mapping, because the multicarrier symbol for including in DwPTS is not fixed, when the multicarrier symbol that DwPTS includes When number is less, it will lead to RE included by two NCCE in a DwPTS by the way of FDD and largely punched；Into And it will affect the decoding performance of NPDCCH.

It based on the above issues and analyzes, this application discloses a solution.In the absence of conflict, the application The feature in embodiment and embodiment in user equipment can be applied in base station, and vice versa.In the absence of conflict, Feature in embodiments herein and embodiment can be arbitrarily combined with each other.
