example 1

[0080]Example 1, the corresponding manner of extension order, and the number of TPC domains in the second TPC domain set is only related to the number of uplink carriers (or simply referred to as carriers) indicated in cc-IndexInOneCC-Set.

[0081] This example assumes that the sequence of uplink carriers indicated in cc-IndexInOneCC-Set is uplink carrier 1, uplink carrier 2, uplink carrier 3, uplink carrier 4, and uplink carrier 5. Then the first TPC domain set is TPC 1, TPC2, TPC3, TPC4, and TPC5, respectively corresponding to the first set cluster of uplink carrier 1 (in some subsequent examples, the SRS resource set cluster is referred to as set cluster for short), and the first set cluster of uplink carrier 2. , the first set of uplink carrier 3, the first set of uplink carrier 4, and the first set of uplink carrier 5.

[0082] After the extension order correspondence method is performed, the second TPC domain set is TPC 1-1, TPC 2-1, TPC 3-1, TPC4-1, and TPC 5-1, respect...

example 2

[0085] Example 2, the corresponding manner of extension order, and the number in the second TPC domain set is related to the number of uplink carriers and the number of set clusters indicated in cc-IndexInOneCC-Set.

[0086] This example assumes that the sequence of uplink carriers indicated in cc-IndexInOneCC-Set is uplink carrier 1, uplink carrier 2, uplink carrier 3, uplink carrier 4, and uplink carrier 5. Then the first TPC domain set is TPC 1, TPC2, TPC3, TPC4, and TPC5, which correspond to the first set of uplink carrier 1, the first set of uplink carrier 2, the first set of uplink carrier 3, and the first set of uplink carrier 4. cluster, the first set cluster of uplink carrier 5.

[0087] In this example, only two set clusters are configured on uplink carriers 2 and 5 of the terminal, and only one set cluster is configured on the other uplink carriers.

[0088] After the extension order correspondence method is performed, the second TPC domain set includes only TPC2-1...

example 3

[0091] Example 3, the interleaving sequence corresponds to the method, and the additional number in the TPC domain set is only related to the number of uplink carriers indicated in cc-IndexInOneCC-Set.

[0092] The corresponding assumptions in this example can refer to Example 1.

[0093] In this example, the order of TPCs in a type A block is as follows, TPC 1, TPC 1-1, TPC 2, TPC 2-1, TPC 3, TPC 3-1, TPC 4, TPC 4-1, TPC 5, TPC 5-1, corresponding to the first set of uplink carrier 1, the second set of uplink carrier 1, the first set of uplink carrier 2, the second set of uplink carrier 2, the first set of uplink carrier 3, and the first set of uplink carrier 3. Two sets of clusters, the first set of uplink carrier 4, the second set of uplink carrier 4, the first set of uplink carrier 5, and the second set of uplink carrier 5.

[0094] In other examples, it is assumed that two set clusters are not configured in uplink carrier 2 (that is, there is only one set cluster), the nu...

Abstract

The embodiment of the invention discloses an SRS power control indication method, a resource cluster division method and equipment, and can solve the problem that power control of an SRS with independent TRP cannot be realized in a multi-TRP scene. The method comprises: a terminal receiving downlink control information (DCI), the DCI comprising a target transmission power control (TPC) domain set, the target TPC domain set being used for indicating power control parameters respectively corresponding to a plurality of SRS resource set clusters in at least one uplink carrier; and sending the SRS according to the power control parameters. According to the embodiment of the invention, the independent power control of the SRS under each TRP can be realized in a multi-TRP scene, and the transmission efficiency of the SRS is improved.

Description

technical field [0001] The present application belongs to the field of communication technologies, and in particular relates to a sounding reference signal (Sounding Reference Signal, SRS) power control indication method, a resource cluster division method, and a device (the device may refer to a terminal or a network side device). Background technique [0002] As a fifth-generation mobile communication system, New Radio (NR) needs to support an unprecedented number of application scenarios, and also needs to support traditional frequency bands, new high frequency bands, and beam modes at the same time, which brings a lot to the design of power control. challenge. [0003] In the related art, only the power control of the Sounding Reference Signal (SRS) is supported in a single transmission receiver point (Transmission Receiver Point, TRP) scenario. With the development of technology, it is necessary to support multiple TRP scenarios. In a multi-TRP scenario, it becomes ne...
