Description
Technical Field
The invention relates to the technical field of communication, in particular to a configuration authorization method under a single subband scene in an LTE230 system.
Background
An LTE (Long Term Evolution) 230 system is a wireless private network communication system operating in a 230MHz frequency band. In the LTE230 system, in view of reducing cost and implementation complexity, a terminal (User Equipment, UE) supports a multi-subband and single-subband operation mode, that is, a terminal receiver supports receiving multiple or single subbands, and is not required to be able to receive all subbands in the LTE230 system. Depending on the hardware capabilities, the terminal may choose to operate on all or some of the subbands, where the simplest and least costly terminal may support operation on a single subband. The setting of the single sub-band working mode reduces the requirement on the receiver bandwidth of the terminal and also reduces the requirement of the LTE230 system on the hardware capability of the terminal.
For a single subband scenario, that is, an interaction scenario between a terminal and a base station under a single subband working model, a PDCCH (Physical Downlink Control Channel) and a PDSCH (Physical Downlink Shared Channel) are time division multiplexed. Due to the bandwidth limitation of the receiver of the single sub-band terminal, DCI (Downlink Control Information) carried on the PDCCH must be independently transmitted on each sub-band. Therefore, it is particularly important to make reasonable use of PDCCH resources.
The existing LTE230 system only supports a dynamic scheduling manner. Although dynamic scheduling can greatly optimize system resource allocation, each resource allocation requires a scheduling instruction to be sent on the PDCCH, introducing the overhead of the PDCCH. Especially, in consideration of periodic services, such as VoIP (Voice over Internet Protocol, Voice over IP) and the like, if such services employ a dynamic scheduling manner, each data packet needs to be scheduled separately by sending a PDCCH, a large PDCCH overhead will be introduced, and it is very likely that the terminal cannot be scheduled in time due to the limitation of PDCCH resources.

Fig. 1 is a schematic diagram of frequency resource distribution of an LTE230 system in the prior art, and as shown in fig. 1, a frequency spectrum of the LTE230 system is comb-shaped, and frequency resources can be divided into a plurality of sub-bands, where a sub-band at a lowest frequency point is 223.525MHz, and a sub-band at a highest frequency point is 231.65 MHz. The LTE230 system supports a power consumption information collection service that collects and analyzes power consumption information of residential users, industrial and commercial users, and specialized users (such as large factories). With the rapid advance of smart grid construction, the LTE230 system needs to provide services such as distribution automation and load management, emergency repair, overhaul, and mobile asset visualization management that support production command for distribution scheduling and distribution network.
The existing LTE230 system only supports a dynamic scheduling manner. Although dynamic scheduling can greatly optimize system resource allocation, when processing periodic traffic, each data packet needs to be separately transmitted in each scheduling, which will introduce a large PDCCH overhead. In a single subband scenario, due to the limitation of the receiver bandwidth of a single subband terminal, it is important to reasonably use the PDCCH resource. In view of the above, the embodiment of the present invention provides a method for configuring and authorizing in a single subband scenario in an LTE230 system.

The base station carries configuration authorization information through RRC signaling, and the configuration authorization information is used for configuring parameters related to uplink and downlink configuration scheduling. And the single subband terminal receives the RRC signaling sent by the base station and analyzes the configuration authorization information from the RRC signaling.
And step 220, configuring parameters related to configuration authorization based on the configuration authorization information.
Specifically, after parsing configuration authorization information from a received RRC signaling, the single subband terminal determines configuration parameters related to configuration authorization according to the configuration authorization information, and uses the configuration parameters in a single subband scenario.
According to the method provided by the embodiment of the invention, the configuration of the configuration authorization related parameters under the single subband scene is realized through the configuration authorization information carried in the RRC signaling, a base station is not required to repeatedly send DCI for resource configuration, the PDCCH overhead is saved, and the resource configuration of the PDCCH is optimized.
Based on the above embodiment, in the method, the configuration authorization information includes the CS-RNTI, and the downlink configuration authorization configuration and/or the uplink configuration authorization configuration.
The CS-RNTI is Configured Scheduling radio network temporary identity Configured Scheduling RNTI. And when the base station issues downlink control information for configuration authorization to the single subband terminal, the base station scrambles the PDCCH based on the CS-RNTI. The downlink configuration authorization configuration config configdl is used for configuring downlink transmission adopting a configuration authorization mode. The uplink configuration grant configuration config is used to configure uplink transmission using a configuration grant scheme.
It should be noted that the configuration authorization information may include a CS-RNTI and a downlink configuration authorization configuration, may also include a CS-RNTI and an uplink configuration authorization configuration, and may also include a CS-RNTI, a downlink configuration authorization configuration, and an uplink configuration authorization configuration, which is not specifically limited in this embodiment of the present invention.
Based on any of the above embodiments, in the method, the downlink configuration grant configuration includes a single subband downlink configuration grant scheduling period and the number of HARQ processes used for downlink configuration grant.
Specifically, the downlink configuration authorization configuration includes establishing or releasing the downlink configuration authorization configuration, and the established downlink configuration authorization configuration includes a single-subband downlink configuration authorization scheduling period and the number of HARQ processes used for downlink configuration authorization.
The single sub-band downlink configuration authorization scheduling period is used for indicating a period of downlink configuration authorization scheduling in a single sub-band working mode. The number of HARQ processes for the downlink configuration grant is used to indicate the number of HARQ (Hybrid Automatic Repeat Request) processes available in the downlink configuration grant.
It should be noted that the scheduling period of the downlink configuration grant of the single subband may be a specific time value, or may be a multiple of the period of the dedicated PDCCH of the terminal, and the corresponding scheduling period of the downlink configuration grant of the single subband may be obtained by the multiple.
Based on any of the above embodiments, in the method, the uplink configuration grant configuration includes a single subband uplink configuration grant scheduling period, the number of HARQ processes used for uplink configuration grant, a supported configuration grant P0 parameter, a configuration grant timer, and an uplink transmission indication of an uplink configuration grant implicitly releasing or skipping configuration grant.

The number of HARQ processes for the uplink configuration grant is used to indicate the number of HARQ processes available in the uplink configuration grant. The supported configuration grant P0 parameter is used to indicate the configuration of the uplink power control parameter P0 in the configuration grant manner. The configuration authorization timer is used for indicating the duration of the configuration authorization timer. The uplink sending instruction of the uplink configuration authorization implicit release is used for indicating the uplink configuration authorization implicit release condition, namely if a single sub-band terminal continuously sends a preset number of MAC PDUs which do not contain MAC SDUs, the uplink configuration authorization is automatically released; and the uplink sending indication for skipping the configuration authorization is used for indicating whether the terminal skips the configuration authorization when no data to be transmitted exists. For a single subband terminal, uplink sending indications of uplink configuration authorization implicit release and skip configuration authorization cannot be used simultaneously, and a base station can only select to configure one of the uplink sending indications of the uplink configuration authorization implicit release and the skip configuration authorization when configuring the uplink configuration authorization for the single subband terminal.
It should be noted that the single subband uplink configuration authorized scheduling period may be a specific time value, or may be a multiple of the dedicated PDCCH period of the terminal, and the corresponding single subband uplink configuration authorized scheduling period may be obtained by the multiple.

Specifically, after the base station completes the configuration of the authorization information for the single sub-band terminal, the base station sends the PDCCH scrambled by the CS-RNTI to activate, reactivate or release the actually allocated configuration authorization resources for the single sub-band terminal. Once the configuration authorization resource is activated, it will be valid periodically until released.
After configuring parameters related to configuration authorization based on the configuration authorization Information, the single sub-band terminal monitors the PDCCH in real time, and if the PDCCH scrambled by the CS-RNTI is received, the single sub-band terminal activates, reactivates or releases the configuration authorization resources according to Downlink Control Information (DCI) carried in the PDCCH scrambled by the CS-RNTI.
When the channel quality of the single subband terminal changes or other conditions that parameters such as the authorized resource, the MCS (Modulation and Coding Scheme), or the repetition number need to be adjusted to be allocated to the single subband terminal occur, the base station issues the DCI to reactivate the configuration authorization. Here, the operation of activating the configuration authorization is similar to the operation of activating the configuration authorization, and the details are not described below.
Based on any of the above embodiments, in the method, the activating, reactivating, or releasing the configuration grant resource based on DCI carried in the PDCCH scrambled based on the CS-RNTI specifically includes:
activating, reactivating or releasing configuration authorized resources based on a value of a designated domain in a format of DCI carried in a PDCCH scrambled by CS-RNTI;
the designated domain comprises a TPC domain, an uplink PID domain and a downlink PID domain, or comprises the TPC domain, the uplink PID domain, the downlink PID domain, First _ f, an uplink MCS, a PUSCH time domain repetition number, an uplink If, a downlink MCS, a PDSCH time domain repetition number and a downlink If.
Here, the configured authorized resources include uplink configured authorized resources and/or downlink configured authorized resources, and activation of the uplink configured authorized resources and the downlink configured authorized resources can be simultaneously achieved based on a value of a designated domain in a format of DCI carried in a PDCCH scrambled by CS-RNTI.
The DCI formats N1, N2, and N3 in the LTE230 system are respectively explained, where table 1 is a PDCCH designated domain setting table for activating authorized resources, and designated domains in the DCI format for activating and configuring authorized resources in table 1 include a TPC domain, an uplink PID domain, and a downlink PID domain:
table 1 activation of a PDCCH special domain for configuring granted resources
| DCI format N1 | DCI format N2 | DCI format N3 | |
| TPC field | Is provided to '00' | N/A | N/A |
| Upstream PID field (Process number) | Is provided as '0' | N/A | Is provided as '0' |
| Down PID field (Process number) | N/A | Is provided as '0' | Is provided as '0' |
When only uplink resource of single subband terminal configuration authorization is to be activated at a certain moment, the uplink resource can be activated
DCI format N1 in table 1, and when only downlink resources are to be activated, DCI format N2 in table 1 may be used for indication; when uplink resources and downlink resources of configuration grant of a single subband terminal need to be activated simultaneously, the uplink resources and the downlink resources may be indicated by DCI format N3 in table 1.
Table 2 is a table for setting a designated domain of PDCCH for releasing authorized resources, where the designated domain in the DCI format for releasing authorized resources in table 2 includes a TPC domain, an uplink PID domain, a downlink PID domain, First _ f, an uplink MCS, a PUSCH time domain repetition number, an uplink If, a downlink MCS, a PDSCH time domain repetition number, and a downlink If:
table 2 releasing the configured granted resource PDCCH special field
When only the uplink resource of the single subband terminal configured with the grant is to be released at a certain time and the downlink resource of the single subband terminal is not to be changed, the indication may be performed through DCI format N1 in table 2, and when only the downlink resource is to be released and the uplink resource is not to be changed, the indication may be performed through DCI format N2 in table 2; when it is necessary to release the uplink resource authorized by the single sub-band terminal configuration and activate the downlink resource authorized by the configuration, or it is necessary to release the downlink resource authorized by the single sub-band terminal configuration and activate the uplink resource authorized by the configuration, or it is necessary to release both the uplink resource and the downlink resource, it may be indicated by DCI format N3 in table 2, if one link direction needs to be released and the other link direction needs to be used normally, the link direction corresponding to the release of the authorized resource sets a special value in the relevant domain of the corresponding direction with reference to table 2, and the relevant domain of the normally used link direction does not set a special value. Based on the above setting, the operation of configuring the authorized resources for the uplink and the downlink simultaneously can be realized through one-time PDCCH, which is beneficial to reducing the data transmission processing time delay in the single sub-band working mode.
It should be added that DCI format N1 is used to schedule uplink resources for the terminal in the single subband operating mode; DCI format N2 is used to schedule downlink resources for a terminal in single subband operating mode; DCI format N3 is used to schedule uplink and downlink resources for a terminal in single subband operating mode. Specific DCI formats are shown in tables 3 to 5.

Based on any of the above embodiments, in the method, if the PDCCH scrambled by the CS-RNTI is received, the method further includes:
if NDI in DCI carried in PDCCH scrambled by CS-RNTI indicates retransmission, resolving HARQ process number in the DCI; and setting the HARQ process number for the authorization configuration as the sum of the HARQ process number in the DCI and the HARQ process number for the authorization configuration.
Specifically, since the LTE230 system cancels a PHICH (Physical Hybrid ARQ Indicator Channel), for uplink Data transmission, new transmission or retransmission is indicated by ndi (new Data indication) in DCI, so as to indirectly know feedback information. For example, for the dynamic scheduling mode, when the NDI field in the DCI is inverted, the DCI is a new transmission, and when the NDI field in the DCI is not changed, the DCI is a retransmission; for the configuration grant scheduling mode, when the value of the NDI field in the DCI is 1, retransmission is indicated. For the same HARQ process, if the NDI indicates retransmission, it indicates that the last transmission corresponding to the HARQ process is NACK (Non-ACKnowledgement), and if the NDI indicates new transmission, it indicates that the last transmission corresponding to the HART process is ack (ACKnowledgement). For the configuration authorization, the integrity of the data packet transmission on one HARQ process is maintained through a configuration authorization timer in the configuration authorization information. For a HARQ process, the configuration authorization timer is started/restarted after each transmission, when the configuration authorization timer is running, the single subband terminal waits for the retransmission scheduling of the process, and new transmission of the process is not allowed until the configuration authorization timer is overtime. And after the configuration authorization timer is overtime, the HARQ process can be used for new transmission. Each HARQ process maintains a configured grant timer.
In addition, when a Physical Uplink Shared Channel (PUSCH) associated with the configuration authorized resource conflicts with the radio resource or the synchronous radio frame occupied by the PUCCH in the scheduling period, the PUSCH skips the radio resource or the synchronous radio frame during resource mapping, and under the condition of repetition, the radio resource does not transmit data, but still needs to be recorded with the number of times of repeated transmission.
When downlink control information for configuring authorization is retransmitted, in a DCI format related to a scheduling single subband, the length of a process number PID field is 1 bit. Thus, only 2 HARQ processes can be indicated by the PID field. The length of the PID field in the DCI is extended, so that the PID field can indicate more HARQ processes, and the direct indication of the HARQ for the configuration authorization is realized. However, considering that the length of the DCI format is limited in a single subband scenario, and extending the length of the DCI format may affect PDCCH demodulation performance, the embodiment of the present invention provides a method for indicating a HARQ process number for grant configuration on the premise of not changing the DCI format:
when the base station generates DCI carried in PDCCH scrambled by CS-RNTI of retransmission, the HARQ process number in the DCI, namely the value of PID domain, is set as the difference value between the HARQ process number used for authorization configuration and the HARQ process number used for authorization configuration, and the DCI is issued.
Correspondingly, after receiving DCI carried in PDCCH scrambled by CS-RNTI, the single subband terminal judges whether the DCI is retransmission, and if so, the HARQ process number for authorization configuration is set as the sum of the HARQ process number in the DCI and the HARQ process number for authorization configuration. In this way, when the single subband terminal receives the retransmission DCI for the configuration authorization, the HARQ process ID may be calculated according to the value of the PID field in the DCI, so that it may be known which process corresponds to the data packet for retransmission.
When the base station generates DCI carried in PDCCH scrambled by C-RNTI, the HARQ process number in the DCI, namely the value of PID domain, is set as the HARQ process number for dynamic scheduling, and the DCI is issued.
Correspondingly, after receiving DCI carried in PDCCH scrambled by C-RNTI, the single subband terminal sets the HARQ process number used for dynamic scheduling as the HARQ process number in the DCI. In other words, for dynamic scheduling, the HARQ process ID corresponding to the initial transmission or retransmission is the value of the HARQ process PID field in the DCI.
In addition, the calculation is performed in the uplink and downlink directions according to the values of the PID fields in the corresponding DCI formats.
Further, the actual HARQ process number HARQ ID can be calculated by the following formula:
wherein, PID is the value of PID field in the downlink control information DCI, and N is the number of HARQ processes for authorization configuration.
Therefore, when receiving the retransmission PDCCH for configuration authorization, the single subband terminal can calculate the HARQ ID according to the value of the PID domain in the PDCCH, thereby knowing which process the corresponding data packet is retransmitted.
In addition, for a new transmission (i.e. initial transmission) with configured grant, its HARQ process ID is not indicated by the value PID of the PID field in the DCI format corresponding to its grant, but calculated by the following formula:
HARQID＝[floor(CURRENT_SFN*25/T)]modNHARQprocesses+NHARQprocesses
wherein, HARQ ID represents actual HARQ process ID, CURRENT _ SFN represents transmission starting radio frame number corresponding to configuration authorization, T is scheduling period of configuration authorization configured by RRC layer, N isHARQprocessesIs the number of HARQ processes configured by the RRC layer for configuration grants.
The method provided by the embodiment of the invention realizes the HARQ process number indication when the PDCCH scrambled by the CS-RNTI is retransmitted on the premise of not changing the format length of the downlink control information for configuring the authorization.
