Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for configuring an SR, a network side device, and a terminal side device.
Background
When a terminal side device, for example, a User Equipment (UE), has uplink traffic to send and does not have uplink shared channel (UL-SCH) resources, a Scheduling Request (SR) is sent to a base station to Request the UL-SCH. Since the SR is transmitted when there is no UL-SCH Resource, the SR is transmitted on a Physical Uplink Control Channel (PUCCH), and the SR can be transmitted only on a Resource configured for Radio Resource Control (RRC). In the prior art, the SR is configured in such a manner that an RRC configuration information is used to configure an SR period and an offset value for determining a resource location where the SR may be transmitted.
In a new air interface unpaired spectrum (NR)/Time Division Duplex (TDD) system, uplink and downlink transmission resources may be configured for a UE through semi-static (semi-static) downlink-uplink configuration (DL-UL configuration), and the UE cannot perform uplink transmission in resources configured in a downlink transmission direction. The UE obtains a slot (slot) for transmitting the SR and a symbol position in the slot according to RRC configuration information (including a period and an offset value) for configuring the SR and a PUCCH resource position for transmitting the SR, that is, an opportunity (opportunity) for transmitting the SR may be obtained, but the opportunity may not be available, and the UE needs to compare an uplink and downlink situation indicated by the position of the SR opportunity and Slot Format Information (SFI) to determine whether the SR can be transmitted in the configured SR opportunity, because the SR can only be transmitted on a symbol (symbol) indicated as UL and/or unknown (unknown) by the SFI, otherwise, the UE needs to wait for the next SR opportunity. When the SFI indicates that the configured SR opportunity is not available, the transmission of the SR needs to be postponed to the next possible transmission time, so that the delay of the SR transmission may be increased, and especially when the SR period itself is small, since the requirement of the UE on the service delay is high, the delay of transmitting the SR may greatly affect the performance of the UE.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In a New Radio (NR) system, the SR supports different cycle configurations, and specifically, the cycle of the SR may be 2 symbols, 7 symbols, one or more slots. The configuration of each SR is configured through RRC signaling, including period (periodicity) and t offset (offset) to indicate which slots and/or symbols can be used to transmit the SR. When the period of the SR is more than one slot, the parameter SR-offset configured by the RRC is a non-negative integer, the UE obtains which slot to transmit the SR in according to the period and the offset, and determines which symbols to transmit the SR on according to a starting symbol (starting symbol) and a symbol number (nrofSymbols) of a PUCCH resource for transmitting the SR in one slot; when the period of the SR is less than one slot, the SR-offset is 0, and the UE utilizes the start symbol of the PUCCH resource for transmitting the SR and the SR period configured by the RRC to pass through the formula
x＝stastartSymbolIndex mod SRperiodicity
And calculating to obtain the initial symbol position of the SR, and determining on which symbols the SR is transmitted by combining the nroflymbols of the PUCCH for transmitting the SR.
In an NR unpaired spectrum (unpaired spectrum)/TDD system, a base station may perform semi-static c DL/UL configuration for a UE through cell-specific high layer signaling (cell-specific high layer signaling). The base station may also perform semi-static DL/UL configuration for the UE through UE-specific high layer signaling (UE-specific high layer signaling). In addition, the base station may also perform dynamic DL/UL allocation for the UE through a dynamic (dynamic) SFI transmitted through a common-group (group-common) PDCCH. Each DL/UL configuration includes a plurality of DL slots/symbols, unswn slots/symbols, and UL slots/symbols, where DL slots/symbols can only be used for downlink transmission, UL slots/symbols can only be used for uplink transmission, and unswn slots/symbols are flexible slots/symbols and can be used for uplink transmission or downlink transmission. If the base station performs DL/UL configuration of semi-static to the UE, the dynamic SFI can only modify slots/symbols indicated as unknown in the semi-static SFI.
After the UE obtains the slot for transmitting the SR and the symbol position in the slot according to the RRC signaling for configuring the SR, the opportunity of the SR may be transmitted, but the opportunity is not necessarily available, and the UE needs to compare the position of the SR opportunity and the uplink and downlink conditions indicated by the SFI to determine whether the SR can be transmitted in the configured SR opportunity, because the SR can only be transmitted on the symbol indicated by the SFI as UL and/or unknown, otherwise, the UE needs to wait for the next SR opportunity. When the SFI indicates that the configured SR opportunity is not available, the transmission of the SR needs to be postponed to the next possible transmission time, so that the delay of the SR transmission may be increased, and especially when the SR period itself is small, since the requirement of the UE on the service delay is high, the delay of transmitting the SR may greatly affect the performance of the UE.
