Example Embodiment

[0065] Example one:

[0066] Suppose that in the CA scenario, the network side equipment configures uplink resources for the primary cell PCell and the secondary cell set {SCell_1, SCell_2, SCell_3} through high-level signaling. Among them, the uplink resources of each cell are configured with multiple SRS resource sets, such as Table 1 shows. Assume that the periodic configuration of the SRS resource set on PCell / SCell_1 / SCell_2 / SCell_3 is T time slot, and the time slot offset is 0 / 1 / 2 / 3 respectively.

[0067] Table 1

[0068]

[0069] When high-level signaling configures SRS carrier switching transmission, the UE will select the SRS resource set for AntennaSwitching for transmission. Such as image 3 As shown, on the PCell, the UE will transmit SRS resource set 3 according to the period T and the slot offset is 0; on SCell_1, the UE will transmit SRS resource set 3 according to the period T and the slot offset is 1. ; On SCell_2, the UE will transmit SRS resource set 3 according...

Example Embodiment

[0070] Example two

[0071] Suppose that the UE receives the SRS configured by the high-level signaling from the network side device and adopts independent power control, adopts the first type of power increase or decrease command, and the SRS resource set includes 0, 1, 2, and 3. Assuming that the SRS power increase or decrease command in the DCI format is {1, -1, +1}, which respectively represent {SRS request field value, SRS set 0 power increase or decrease command, SRS set 1 power increase or decrease command}. The SRS request field value is 2 corresponding to the first SRS list, including SRS resource sets 0 and 1.

[0072] The definition of the SRS request field in the DCI format is shown in Table 2.

[0076] Example three

[0077] Suppose that the UE receives the SRS configured by the high-level signaling from the network side device and adopts independent power control, and adopts the second type of power increase or decrease command, and the SRS resource set includes 0, 1, and 2. Assuming that the SRS power increase or decrease commands in the DCI format are {'01', -1}, {'10', 0}, {'11', +1}, which respectively represent {SRS request field value, SRS aggregate N power Raise or lower commands}.

[0078] The definition of the SRS request field in the DCI format is shown in Table 3.

Abstract

The invention provides a sounding reference signal transmission method, a sounding reference signal configuration method, user equipment and network side equipment, and belongs to the technical fieldof communication. The sounding reference signal SRS transmission method is applied to the user equipment, and comprises the following steps: receiving uplink resources of at least one cell from network side equipment, the uplink resources of each cell comprising at least one SRS resource set; and selecting at least one SRS resource set on each cell to send according to a preset rule in a scene inwhich the SRS is switched and sent between carriers, the scene being configured for the network side device. According to the technical scheme of the invention, all channel state information can be efficiently obtained, and the system transmission rate is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a sounding reference signal transmission and configuration method, user equipment and network side equipment. Background technique [0002] In the fifth generation (5th Generation, 5G) mobile communication system, according to the different functions of Sounding Reference Signal (SRS), SRS can be used for beam management (Beam management), codebook-based transmission, non-code-based This (non-Codebook) transmission, antenna switching (Antenna Switching) transmission. A user equipment (User Equipment, UE) can obtain multiple SRS resource sets and configurations through high-layer signaling, and each SRS resource set configuration includes its use, period characteristics, and the like. [0003] In the carrier aggregation (Carrier Aggregation, CA) scenario, when high-level signaling configures multiple SRS resource sets for transmission, the SRS resource set used for...
