Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). According to various embodiments, a method performed by a Distributed Unit (DU) may include: generating configuration information for packets used in uplink data transmission of a plurality of Radio Units (RUs) providing a shared cell, and transmitting the configuration information for packets to an RU among the plurality of RUs through a fronthaul interface. The configuration information for packets may include information for indicating the number of per-packet Physical Resource Blocks (PRBs) for the uplink packets.

First claim

What is claimed is:

1 . A method performed by a Distributed Unit (DU), comprising:
generating configuration information for packets used in uplink data transmission of a plurality of Radio Units (RUs) providing a shared cell; and transmitting the configuration information for packets to an RU among the plurality of RUs through a fronthaul interface, wherein the configuration information for packets includes information for indicating the number of per-packet Physical Resource Blocks (PRBs) for the uplink packets.

2 . The method of claim 1 , wherein the number of per-packet PRBs is indicated by a range of the per-packet PRBs.

3 . The method of claim 1 , wherein the number of per-packet PRBs comprises the maximum number of PRBs usable for each packet based on the RU transmitting packets used in the uplink data transmission.

4 . The method of claim 1 ,
wherein the DU and the RU are coupled through a Fronthaul Multiplexer (FHM) or a different RU, and wherein the FHM and the different RU include the shared cell.

5 . The method of claim 1 , further comprising receiving capability information for the uplink data transmission of the RU, from the RU through the fronthaul interface.

6 . The method of claim 1 , further comprising:
determining the number of packets used in the uplink data transmission of the RU; and transmitting information on the determined number of packets to the RU.

7 . The method of claim 6 , wherein the number of packets is determined based on a bandwidth and Subcarrier Spacing (SCS) of a signal for transmitting uplink data.

8 . The method of claim 1 , further comprising:
determining a transmission order of packets used in the uplink data transmission of the RU; and transmitting information on the determined transmission order of packets to the RU.

9 . The method of claim 8 , wherein the transmission order of the packets is set in the order from a packet having a low PRB number to a packet having a high PRB number among the packets used for the uplink data transmission.

10 . A method performed by a Radio Unit (RU), comprising:
receiving configuration information for packets used in uplink data transmission of the RU, from a Distributed Unit (DU) through a fronthaul interface; and transmitting uplink data, based on the received configuration information for packets, wherein the configuration information for packets includes information indicating a number of per-packet Physical Resource Blocks (PRBs) for the uplink packets, and wherein the RU is included in a plurality of RUs providing a shared cell.

11 . The method of claim 10 , wherein the number of per-packet PRBs is indicated by a range of the per-packet PRBs.

12 . The method of claim 10 , wherein the number of per-packet PRBs includes the maximum number of PRBs usable for each packet based on the RU transmitting packets used in the uplink data transmission.

13 . The method of claim 10 ,
wherein the DU and the RU are coupled through a Fronthaul Multiplexer (FHM) or a different RU, and wherein the FHM and the different RU include the shared cell.

14 . The method of claim 10 , further comprising transmitting capability information for the uplink data transmission of the RU, to the DU through the fronthaul interface.

15 . The method of claim 10 , further comprising receiving information on the determined number of packets from the DU.

16 . The method of claim 15 , wherein the number of packets is determined based on a bandwidth and Subcarrier Spacing (SCS) of a signal for transmitting uplink data.

17 . The method of claim 10 , further comprising receiving information on the determined transmission order of packets from the DU.

18 . The method of claim 17 , wherein the transmission order of the packets is set in the order from a packet having a low PRB number to a packet having a high PRB number among the packets used for the uplink data transmission.

19 . A Distributed Unit (DU) comprising:
a transceiver; and at least one processor operatively coupled to the transceiver, wherein the at least one processor is configured to: generate configuration information for packets used in uplink data transmission of a plurality of Radio Units (RUs) providing a shared cell; and transmit the configuration information for packets to an RU among the plurality of RUs through a fronthaul interface, wherein the configuration information for packets includes information indicating a number of per-packet Physical Resource Blocks (PRBs) for the uplink packets.

20 . The DU of claim 19 , wherein the number of per-packet PRBs is indicated by a range of the per-packet PRBs.
