Description

幾つかの実装形態によれば、方法は、第１のネットワークデバイスにより、ランクのグループのランクのためのそれぞれのポート番号の指示を第２のネットワークデバイスに送信することを含み得る。それぞれのポート番号を特定することは、使用可能なポートをポートの２つのグループにパーティションで区切ることを含み得る。 According to some implementations, the method may include sending, by the first network device, an indication of respective port numbers for ranks of the group of ranks to the second network device. Identifying each port number may include partitioning the available ports into two groups of ports.

コンピューター実装方法８００の８０２において、各ランクのために用いられるポート番号は、第１のネットワークデバイス（例えば、一次ネットワークデバイス）によって特定することができる。幾つかの実装形態によれば、各ランクのために用いられるポート番号を特定することは、利用可能なポートをポートの２つのグループにパーティションで区切ることを含み得る。情報は、コンピューター実装方法８００の８０４において、第２のネットワークデバイスと交換することができる。 At 802 of computer-implemented method 800, the port number used for each rank can be specified by a first network device (eg, primary network device). According to some implementations, identifying the port numbers to be used for each rank may include partitioning the available ports into two groups of ports. Information can be exchanged with a second network device at 804 of the computer-implemented method 800 .

コンピューター実装方法８００は、ＤＭＲＳシンボルへの干渉が最小化及び／又は低減されるように、ＴＲＰ間の準静的協調を容易にすることができる。本明細書中で検討するように、２つのＴＲＰ（例えば、第１のネットワークデバイス、第２のネットワークデバイス）は、各ランクのために用いられるポート番号を事前に特定することができる。例えば、２つ（以上）のＴＲＰは、干渉が最小化及び／又は低減されるように、使用可能なＤＭＲＳポートをパーティションで区切ることができる。加えて、ＴＲＰは、ＰＤＳＣＨが他のＴＲＰのリソース要素でスケジュール設定されないことに同意することができる（例えば、干渉を回避するため）。 Computer-implemented method 800 can facilitate semi-static coordination between TRPs such that interference to DMRS symbols is minimized and/or reduced. As discussed herein, two TRPs (eg, first network device, second network device) can pre-specify the port number to be used for each rank. For example, two (or more) TRPs can partition the available DMRS ports such that interference is minimized and/or reduced. Additionally, TRPs can agree that the PDSCH is not scheduled on resource elements of other TRPs (eg, to avoid interference).

コンピューター実装方法１０００は、第１のネットワークがランクのグループのランクのためのそれぞれのポート番号を特定する（例えば、分析構成要素９２４を介して）場合、１００２において開始する。一例において、それぞれのポート番号を特定することは、使用可能なポートをポートの２つのグループにパーティションで区切ることを含み得る。幾つかの実装形態によれば、ランクのグループのランクのためのそれぞれのポート番号の指示は、第２のネットワークデバイスに送信され得る。 Computer-implemented method 1000 begins at 1002 when a first network identifies respective port numbers for ranks of a group of ranks (eg, via analysis component 924). In one example, identifying each port number may include partitioning the available ports into two groups of ports. According to some implementations, an indication of respective port numbers for ranks of a group of ranks may be sent to the second network device.
