Description
Technical field
The present invention relates to wireless communication technology fields, in particular to support can dynamic under 5G NR consensus standard for one kind
Configure the method that the measurement resource for executing measurement is chosen by user equipment in the wireless communications environment of uplink downlink resource
And equipment and system corresponding to this method.
Background technique
In existing wireless communication technique, needs to execute communication process many indexes measurement, including but not limited to receive
Signal strength indicator (RSSI) measurement, Reference Signal Received Power (RSRP) measurement, Reference Signal Received Quality (RSRQ) are surveyed
Amount and radio link monitoring (RLM) measurement etc., execute as described above these measurement with to communication link quality carry out measure with
Evaluation, and the operations such as instruction execution such as, but not limited to carries out inter-cell soft handoff, link reconfigures in turn, so that channel radio
Believe that quality and performance are more excellent.
In executing measurement process as above, due to or there are interference between neighboring community or the same communication path
Interference between middle uplink downlink further is even further directed to not be statically configured or fix to uplink and downlink resource,
Therefore, suitable measurement resource how is chosen, accurately objectively to reflect that be measured is also in the prior art urgently to be resolved one
A technical problem.
In the prior art, a variety of methods for measuring have been had already appeared, such as application No. is WO2012KR11254
Document 1, which describe one kind, and dynamic to be supported to change the environment of the amount of uplink (UL) and downlink (DL) resource
The method that the measurement of user equipment (UE) is supported in wireless access system, in this method based in adjacent eNB same asset be
The measurement resource is determined for DL or UL, and this method further can also be only used for by the adjacent eNB
The measurement resource is configured in the subframe of DL transmission.Also for example application No. is WO2003IB01599 document 2, which describe one
Estimated signal quality is planted to avoid the communication means of uplink channel interference, signal strength can be same site (co-sited) load
The received signal strength indicator (RSSI) of the down link signal of wave.Also for example application No. is CN200910195249.1 document 3,
Which describe be a TDD (Time Divide Duplex: time division duplex) system and all TDD systems due to TD-LTE
Equally, uplink interference is not can avoid the problem of；During frequency sweep, terminal is in order to search for and identify network, it is necessary to
The continuous data for carrying out the long period receives；In the process, receive data be inevitably mixed into around other terminals it is upper
Row sends signal, is polluted so as to cause data are received；Therefore it is proposed: synchronizing information is obtained, with bandwidth
The data in predetermined time domain scale are received based on the synchronizing information in the frequency band of range, wherein in the predetermined time domain scale not
There are terminal uplink signals, carry out frequency-domain transform to data are received to obtain the sub-carrier frequency domain data in the frequency band, go forward side by side
And strength of carrier is calculated to help to realize frequency sweep.
The prior art as above or the configuration based on neighboring community and select the resource measured, to avoid from adjacent
The interference of the current resource to be measured of the link pair of cell, or consider the interference between uplink downlink and select in downlink
It is upper to execute measurement.However it is ascending resource and under which is which these prior arts, which do not consider how to select fully,
Row resource, especially uplink and downlink resource not be fixed setting in the case where, such as certain sign bits and be not known be
For uplink perhaps downlink or certain sign bits be set to can be changed/can configure/it is rewritable, in this case, with which kind of
Mode judges and selects the resource measured, is provided in particular in a kind of selection mechanism that expression effect is firm, this is also
The problems of in the prior art.

Carry out rssi measurement.Configurable measurement resource is relatively flexible, can indicate which time slot can be used for measuring and which when
Which symbol of gap can measure, but flexibility ratio is also limited, for example, 5G NR only indicates that 4 kinds of other resources of symbol level refer to
Show, is preceding 2 symbols, preceding 6 symbols, preceding 8 symbols and preceding 12 symbols in a time slot respectively.
However, the configurable measurement that the option and 5G NR of default measurement resource defined in 5G NR define at present
The configuration parameter of resource cannot evade the problem of relying on ascending resource to do rssi measurement completely, and basic reason is 5G NR
With flexible uplink and downlink resource distribution and flexible uplink and downlink resource rewrite method, so that by predefined resource or having
The mode of limit configuration resource is difficult to determine the rssi measurement resource of one group of exclusion ascending resource completely.For example, since 5G NR has
There are flexible uplink and downlink resource distribution and flexible uplink and downlink resource rewrite method, will lead to the portion in the measurement resource of RSSI
Slot or symbol (symbol for being especially in flexible state) is divided to be possible to scheduled or be rewritten as uplink
Symbol, as shown in Figure 1, the time slot characterization sign bit that can be changed of blank namely the sign bit of uncertain uplink and downlink in the Fig. 1.This
The measurement resource or configurable measurement resource defaulted a bit need to evade as much as possible introducing ascending resource and do RSSI survey for UE
Amount, otherwise will affect the performance of measurement, so that the problems such as bringing ambulant wrong choice.
The present invention uses following technical term:
UE: user equipment (User Equipment)
SMTC:RRM measures timing configuration (SS block based RRM measurement timing configuration)

The location information of character position and other ascending resources.
Since the embodiment of the present invention will weed out in the preset measurement resource information for measuring for uplink
The symbol of transmission, namely the sign bit for not selecting those to be used for uplink, therefore will be according to uplink in the embodiment of the present invention
Resource information has been used for uplink to orient which sign bit, and specifically, when uplink and downlink timeslot configuration, uplink
The common information for positioning ascending resource position can help to implement in domain character position, frequency domain symbol position, etc. this field
Method of the invention.Due to that can be configured, set or be rewritten for certain sign bits in 5G NR, it is therefore desirable to pass through this
It invents implemented method and knows which sign bit belongs to ascending resource in real time in time.
Step 3, it is rejected acquired in the user equipment in the preset measurement resource information for measuring
Know ascending resource information；
Step 4, the measurement resource information after being rejected based on execution in step 3 realizes measurement.
