Abstract

Apparatuses, methods, and systems are disclosed for determining linked bandwidth parts. One method includes determining that a plurality of bandwidth parts is activated. The method includes determining that a scheduling resource is configured on the plurality of bandwidth parts, semi-persistent scheduling is configured on the plurality of bandwidth parts, or a combination thereof. The method includes determining a bandwidth part of the plurality of bandwidth parts to use for an uplink transmission.

First claim

1 . A method comprising:
determining that a plurality of bandwidth parts is activated; determining that a scheduling resource is configured on the plurality of bandwidth parts, semi-persistent scheduling is configured on the plurality of bandwidth parts, or a combination thereof; and determining a bandwidth part of the plurality of bandwidth parts to use for an uplink transmission.

2 . The method of claim 1 , wherein determining the bandwidth part to use for the uplink transmission comprises determining the bandwidth part of the plurality of bandwidth parts that is the earliest available in a time domain.

3 . The method of claim 1 , wherein determining the bandwidth part to use for the uplink transmission comprises determining the bandwidth part of the plurality of bandwidth parts that has a highest priority.

4 . The method of claim 1 , wherein determining the bandwidth part to use for the uplink transmission comprises determining the bandwidth part of the plurality of bandwidth parts that is a primary bandwidth part.

5 . An apparatus comprising:
a processor that:
determines that a plurality of bandwidth parts is activated;
determines that a scheduling resource is configured on the plurality of bandwidth parts, semi-persistent scheduling is configured on the plurality of bandwidth parts, or a combination thereof; and
determines a bandwidth part of the plurality of bandwidth parts to use for an uplink transmission.

6 . The apparatus of claim 5 , wherein the processor determines the bandwidth part to use for the uplink transmission by determining the bandwidth part of the plurality of bandwidth parts that is the earliest available in a time domain.

7 . The apparatus of claim 5 , wherein the processor determines the bandwidth part to use for the uplink transmission by determining the bandwidth part of the plurality of bandwidth parts that has a highest priority.

8 . The apparatus of claim 5 , wherein the processor determines the bandwidth part to use for the uplink transmission by determining the bandwidth part of the plurality of bandwidth parts that is a primary bandwidth part.

9 . The apparatus of claim 5 , further comprising a receiver, wherein the processor determining the bandwidth part to use for the uplink transmission comprises the receiver receiving information indicating the bandwidth part.

10 . The apparatus of claim 9 , wherein the information indicating the bandwidth part comprises an index value corresponding to the bandwidth part.

11 . A method comprising:
determining that a plurality of bandwidth parts is configured; determining that the plurality of bandwidth parts has configured random access channel resources; transmitting a first random access message on an uplink bandwidth part of the plurality of bandwidth parts; and receiving a second random access message on a downlink bandwidth part of the plurality of bandwidth parts.

12 . The method of claim 11 , wherein the uplink bandwidth part is linked to the downlink bandwidth part.

13 . The method of claim 11 , further comprising receiving information indicating the downlink bandwidth part.

14 . The method of claim 11 , further comprising receiving information indicating the uplink bandwidth part.

15 . The method of claim 11 , further comprising receiving information indicating a serving cell corresponding to the uplink bandwidth part.

16 . An apparatus comprising:
a processor that:
determines that a plurality of bandwidth parts is configured; and
determines that the plurality of bandwidth parts has configured random access channel resources;
a transmitter that transmits a first random access message on an uplink bandwidth part of the plurality of bandwidth parts; and a receiver that receives a second random access message on a downlink bandwidth part of the plurality of bandwidth parts.

17 . The apparatus of claim 16 , wherein the uplink bandwidth part is linked to the downlink bandwidth part.

18 . The apparatus of claim 16 , wherein the receiver receives information indicating the downlink bandwidth part.

19 . The apparatus of claim 16 , wherein the receiver receives information indicating the uplink bandwidth part.

20 . The apparatus of claim 16 , wherein the receiver receives information indicating a serving cell corresponding to the uplink bandwidth part.
