Description

A kind of configuration method, the network equipment and the user equipment of the co-located information of standard

Technical field

The present invention relates to field of communication technology more particularly to a kind of configuration method, the network equipment and the use of the co-located information of standard Family equipment.

Background technique

In the current design that the 5th generation (5 Generation, 5G) newly eats dishes without rice or wine (NR) mobile communication system, user equipment (UE) it needs to configure by search space, determines the tim e- domain detection position of control channel, and control can be associated in the configuration of search space Resource set (Control Resource set, CORESET) processed is configured with the frequency domain position of control channel appearance in CORESET, Bandwidth, transmission configuration indicate information such as (TCI).

TCI specifies co-located (Quasi Co-Location, the QCL) relationship of standard of CORESET and reference signal, in TCI It may include multiple QCL relationships, specific control channel can intervene control layer by media using which QCL relationship and control member Plain (MAC Control Element, MAC CE) configuration.

If the signal of two antenna ports meets QCL relationship, two signals emitted from the two antenna ports, Large scale characteristic experienced is similar.Large scale characteristic includes Doppler frequency shift (Doppler shift), doppler spread (Doppler spread), average delay (average delay), delay spread (delay spread), space receive parameter (Spatial Rx parameter) etc..Assuming that two antenna ports are QCL, be conducive to receiver processing, such as from one The channel estimation results obtained on antenna port can be used for another antenna port.Specifically, QCL type (QCL type) can Include:

QCL type A, quasi- co-located parameter includes: Doppler frequency shift, doppler spread, average delay and delay spread；

QCL type B, quasi- co-located parameter includes: Doppler frequency shift and doppler spread；

QCL Type C, quasi- co-located parameter includes: average delay and Doppler frequency shift；

QCL type D, quasi- co-located parameter include: that space receives parameter.

For passing through the search space and CORESET of high-rise wireless heterogeneous networks (RRC) signal deployment, used in transmitting and scheduling When the scheduling control information of the exclusive Traffic Channel in family, due to Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) QCL relationship can pass through RRC signaling combination MAC CE determine, therefore, user equipment and base station (gNB) The understanding that can reach an agreement.

For the CORESET#0 of Physical Broadcast Channel (Physical Broadcast Channel, PBCH) configuration, usually For transmit remaining minimum system information (RMSI) schedules control channels.When configuring CORESET#0, can use 8 bits in PBCH indicate the bandwidth of CORESET, the time domain money of time duration and PDCCH detection (monitoring) Source position.CORESET#0 can also be used to the schedules control channels of transmission paging (paging), OSI and RAR etc..Due to these Information is broadcast message, can be transmitted numbering in (SSB index) associated CORESET#0 with each SSB, therefore CORESET#0 can't usually specify QCL relationship.Here, in 5G NR, primary synchronization signal (PSS), secondary synchronization signal (SSS) It is collectively formed a SSB (SS/PBCH block) with PBCH, SSB occupies 4 OFDM symbols altogether in the time domain, and frequency domain occupies altogether 240 subcarriers (20 PRB).

But schedule unicast Physical Downlink Shared Channel (Physical Downlink is used for when transmitting in CORESET#0 Shared Channel, PDSCH) PDCCH when, if still will lead to base station and UE pairs without corresponding QCL relationship The cause that understands differently of CORESET#0.

For example, it is based on existing mechanism, high-level signaling is that UE is configured with the exclusive search space of user equipment, this Search space is associated with CORESET#0, and the type of search space is UE specific.I.e. user equipment will be examined in CORESET#0 The exclusive search space of user equipment is surveyed, the scheduling information of PDSCH is obtained.So, when the position of UE changes, user is received To the stronger SSB index of signal may have occurred variation, the corresponding time-domain resource position for receiving RMSI will become Change.Namely in this case, UE receive PDCCH position become with the associated position CORESET new SSB index, And current base station is not aware that, therefore just will appear transmission for dispatching the position PDCCH and the UE detection of unicast PDSCH The different situation in position, cause UE that can not receive control channel.
