Background
The 5G is used as a main technology of a next-generation wireless network and has the technical characteristics of supporting ultra wide band, large connection and the like. For the problem of insufficient Uplink coverage of 5G, a concept of SUL (supplemental Uplink) carrier is introduced into 3GPP Release 15, and a main idea of the concept is to use a carrier of a low frequency band as a supplemental carrier of an NR (New Radio, New air interface) high frequency band to solve the problem of insufficient Uplink coverage of NR.

Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only some embodiments of the present disclosure, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by one of ordinary skill in the art from the embodiments disclosed herein without making any creative effort, shall fall within the scope of protection of the present disclosure.
The present disclosure provides a communication method, which can flexibly configure PUCCH resources for a terminal, and is described below with reference to fig. 1.
Fig. 1 is a flow chart of some embodiments of the disclosed communication method. As shown in fig. 1, the method of this embodiment includes: steps S102 to S106.
In step S102, the base station receives capability report information sent by the terminal. The capability reporting information comprises the terminal supported frequency bands.
After accessing the network, the terminal can report the capability to the base station, carrying the frequency band information supported by the terminal. For example, NUL may employ the 3.5GHz band and SUL may employ the 2.1GHz band. The base station can determine which types of carriers are supported by the terminal according to the supported frequency bands reported by the terminal. The capability reporting information may also include an SUL frequency band combination capability, which indicates that the terminal can simultaneously support the NUL and SUL carriers.
In some embodiments, the capability reporting information may further include: and the PUCCH configuration indication identifier is used for indicating that the terminal can accept the configuration of PUCCH resources on a plurality of carriers supported by the terminal by the base station. And the base station determines the subsequent time-frequency resources of the multiple carriers according to the identifier to configure PUCCH resources for the terminal. For example, the capability field of the terminal includes a PUCCH configuration indication identifier, SulNulPUCCHconfig field, which may be an enumerated field, and when the field indicates supported, it indicates that the terminal supports PUCCH resource configuration on SUL and NUL carriers, so that a subsequent field performs PUCCH resource configuration on SUL and NUL carriers for the terminal according to the field.
In step S104, the base station configures PUCCH resources for the terminal in the time-frequency resources of multiple carriers according to the carrier corresponding to the frequency band supported by the terminal, and sends the configuration information to the terminal.
The configuration information includes, for example: information of the configured PUCCH resources, for example, an identifier of a time-frequency resource occupied by a plurality of configured PUCCH resources. The configuration information may be transmitted to the terminal through RRC (Radio Resource Control) configuration signaling. The configuration information may also include other information in the current standard, which is not described herein again.
The carriers disclosed herein include FDD carriers and TDD carriers with different subframe configurations, and the Numerology (parameter set) of each carrier may be the same or different. The carrier may be various combinations of uplink time slots and downlink time slots, and the carrier is not limited to bands (frequency bands) and includes various Band combinations.
In some embodiments, the base station selects time-frequency resources on multiple carriers to configure PUCCH resources for the terminal according to carriers corresponding to frequency bands supported by the terminal and at least one of load, coverage and delay of each carrier. The base station may select a carrier with a load lower than a load threshold as a carrier configured by the PUCCH resource according to a load condition of the carrier. The base station may select, for the terminal, a carrier that can cover the terminal as a carrier for PUCCH resource configuration according to the location of the terminal and the coverage of the carrier. The base station can select the carrier with the time delay lower than the time delay threshold value as the carrier configured by the PUCCH resource according to the transmission time delay of the carrier.
And the base station configures PUCCH resources for the terminal according to the information such as the load, the coverage area, the time delay and the like of each carrier. The load of each carrier can be balanced, and meanwhile, when the subsequent terminal carries out downlink scheduling feedback or uplink scheduling, PUCCH resources which are more timely and effective can be selected for the terminal.
In some embodiments, when the base station selects multiple carriers to configure PUCCH resources for the terminal, if the multiple carriers include two carriers, namely NUL and SUL, the slots of the PUCCH resources configured on the NUL and SUL by the base station do not overlap when the NUL and SUL are transmitted in a time division manner. Namely, when the base station configures the PUCCH resource, the uplink carrier concurrence can be avoided in a manner of time domain staggering of the PUCCH resource. The PUCCH resource concurrence may also be avoided through scheduling when a downlink scheduling feedback indication is subsequently sent to the terminal, which will be described later.
In step S106, the base station selects one or more configured PUCCH resources as a feedback resource for downlink scheduling, and indicates the selected PUCCH resources to the terminal, so that the terminal performs feedback for downlink scheduling.
The feedback of downlink scheduling by the terminal includes, for example, the terminal transmitting HARQ-ACK/NACK (hybrid automatic repeat request acknowledgement information) to the base station. HARQ-ACK/NACK may be carried in UCI (uplink control information). The base station may indicate the selected PUCCH resource to the terminal through information such as RRC or DCI (downlink control information) when performing downlink scheduling on each carrier. For example, the base station reuses an indicator bit of the UL/SUL indicator in DCI during downlink scheduling to indicate which SUL or NUL the PUCCH feedback of the current downlink scheduling is fed back on. The downlink scheduling indication information sent by the base station to the terminal may also carry other information besides the selected PUCCH resource, for example, PUCCH format, and the like, and may refer to information carried in the current standard, which is not described herein again
In some embodiments, the base station selects, as a feedback resource for downlink scheduling, an uplink time-frequency resource configured with a PUCCH resource after a downlink scheduling time slot and having a time difference with the downlink scheduling time slot within a preset range, where the feedback resource for downlink scheduling includes PUCCH resources on one or more carriers. Namely, the base station judges which uplink time slots after the current downlink scheduling time slot allocate PUCCH resources for the terminal, and selects PUCCH resources with the time difference with the current downlink scheduling time slot within a preset range from the PUCCH resources so as to improve the feedback efficiency. Further, the base station may select a PUCCH resource indicating terminal of the uplink slot with the smallest time difference with the current downlink scheduling slot to perform feedback on the PUCCH resource.
In some embodiments, the base station may select only one PUCCH resource as a feedback resource of the terminal, and the terminal only needs to perform feedback on the resource.
In some embodiments, in a case that the base station selects multiple configured PUCCH resources as a feedback resource for downlink scheduling, the terminal may select the feedback resource on a carrier with a short feedback time. Different carriers may have different feedback delays due to the transmission capability of the network device or whether the terminal needs to perform carrier switching, and the like, and the terminal selects a feedback resource on a carrier with short feedback time.
In some embodiments, when the base station selects a plurality of configured PUCCH resources as feedback resources for downlink scheduling, and the plurality of feedback resources are located in a NUL carrier and a supplemental uplink SUL carrier, respectively, the terminal selects one feedback resource from the plurality of feedback resources for uplink feedback for downlink scheduling, and the selection method includes: and selecting feedback resources on the NUL carrier, or selecting feedback resources on the carrier with short feedback time. If the feedback resources are respectively located in the NUL carrier and the SUL carrier, the terminal can preferentially select the NUL carrier for feedback, or select the carrier for feedback according to the feedback time. In this case, if the base station does not time-stagger PUCCH resources on the NUL and SUL carriers when performing PUCCH configuration, a situation that PUCCH resources on the NUL and SUL carriers overlap or partially overlap may occur, and the base station should avoid instructing the terminal to perform feedback on the NUL and SUL carriers simultaneously as much as possible.
As shown in fig. 2, an application scenario is that, when NUL and SUL are transmitted in a time division manner, a network side may flexibly indicate a downlink scheduling feedback time based on a UL/SUL indicator, a timeslot ratio of a NUL carrier is DDDSUDDSUU, a downlink feedback of Dslot may be transmitted in a closest uplink timeslot PUCCH on a SUL carrier of a 2.1G band (an arrow indicates an uplink feedback timeslot corresponding to a downlink timeslot), and a downlink feedback of S slot (a special timeslot) may be transmitted in a closest uplink timeslot PUCCH on a NUL carrier of a 3.5G band.
In some embodiments, the base station adjusts the configuration of the PUCCH resources according to at least one of the coverage or load of one or more carriers for which PUCCH resources have been configured. For example, when the coverage of the carrier cannot cover the position of the terminal, the PUCCH resource allocated on the carrier is released. Or, when the load of the carrier exceeds the load threshold, releasing the PUCCH resource configured on the carrier. Meanwhile, the base station can also configure PUCCH resources for the terminal by adding carriers meeting the coverage range and the load condition, and the base station can configure or release the PUCCH resources based on a setup-release mechanism in the protocol without the need of the terminal to perform random access again. And the visible terminal at the fuzzy period network side randomly adopts the original PUCCH resource configuration until the RRC configuration is completed.
In the method of the above embodiment, the base station configures PUCCH resources for the terminal in the time-frequency resources of multiple carriers according to the frequency band information supported by the terminal, and sends the configuration information to the terminal, and then the base station may select one of the multiple configured PUCCH resources of multiple carriers as a feedback resource for downlink scheduling. The base station can allocate timely and effective feedback resources to different terminals when indicating the feedback resources of downlink scheduling for the terminals, so that the terminals can timely and effectively perform downlink scheduling feedback, and meanwhile, the resource utilization rate of uplink time slots can be improved.
Further embodiments of the communication method of the present disclosure are described below in conjunction with fig. 3.
Fig. 3 is a flow chart of some embodiments of the disclosed communication method. As shown in fig. 3, the method of this embodiment includes: steps S302 to S308.
In step S302, the base station receives capability report information sent by the terminal. The capability reporting information comprises the terminal supported frequency bands.
In step S304, the base station configures PUCCH resources for the terminal in the time-frequency resources of multiple carriers according to the carrier corresponding to the frequency band supported by the terminal, and sends the configuration information to the terminal.
The base station may configure PUCCH resources for the terminal, where the PUCCH resources include PUCCH SR (uplink scheduling) resources.
In step S306, the base station receives an uplink scheduling request from the terminal, and allocates PUCCH uplink scheduling resources to the terminal.
In step S308, the terminal selects an uplink scheduling resource from PUCCH uplink scheduling resources configured for the terminal by the base station to transmit uplink information.
When the terminal initiates an uplink scheduling request by itself, the terminal can select PUCCH resources of SUL or NUL carriers to perform SR reporting based on PUCCH configuration of the network side by itself. At this time, the network side can schedule any uplink carrier.
