Abstract
A method and an apparatus for configuring a channel carrier, user equipment and a base station are provided. The method of configuring a channel carrier includes: a message carrying channel carrier configuration information sent by a base station is received, where the channel carrier configuration information indicates at least one of numerology or TTI configuration information for a logical channel; and each carrier mapped to the logical channel and at least a numerology or a TTI configured for each carrier mapped to the logical channel are determined based on the channel carrier configuration information.
Claims22
A method comprising:
- receiving a first message, wherein the first message is a message carrying channel carrier configuration information sent by a base station, wherein the channel carrier configuration information indicates at least one of numerology or transmission time interval (TTI) configuration information for a logical channel;
- and
- determining at least one carrier mapped to the logical channel and at least a numerology or a TTI configured for at least one carrier mapped to the logical channel, based on the channel carrier configuration information;
- wherein receiving the first message comprises:
- receiving a Radio Resource Control (RRC) message carrying the channel carrier configuration information sent by the base station;
- and
- the method further comprises:
- when the RRC message is an RRC message instructing user equipment to switch to an inactive state, the RRC message further carries at least respective numerologies or TTIs configured for different carriers associated with the logical channel;
- determining a carrier for a cell when the user equipment in the inactive state resides in the cell;
- and
- determining at least a numerology or a TTI configured for the carrier for the cell with respect to the logical channel, based on the carrier for the cell.
8 more elements
A method comprising:
- generating a first message, wherein the first message is a message carrying channel carrier configuration information, wherein the channel carrier configuration information indicates at least one of numerology or transmission time interval (TTI) configuration information for a logical channel;
- and
- sending the first message to user equipment, wherein the first message is configured for the user equipment to determine at least one carrier mapped to the logical channel and at least a numerology or a TTI configured for at least one carrier mapped to the logical channel;
- wherein the first message comprises a Radio Resource Control (RRC) message;
- and
- wherein when the RRC message is an RRC message instructing user equipment to switch to an inactive state, the RRC message further carries at least respective numerologies or TTIs configured for different carriers associated with the logical channel, such that the user equipment determines a carrier for a cell when the user equipment in the inactive state resides in the cell, and determines at least a numerology or a TTI configured for the carrier for the cell with respect to the logical channel, based on the carrier for the cell.
3 more elements
User equipment, comprising:
- one or more processors;
- and
- non-transitory computer-readable storage medium storing instructions executable by the one or more processors;
- wherein the one or more processors are configured to:
- receive a first message, wherein the first message is a message carrying channel carrier configuration information sent by a base station, wherein the channel carrier configuration information indicates at least one of numerology or transmission time interval (TTI) configuration information for a logical channel;
- and
- determine at least one carrier mapped to the logical channel and at least a numerology or a TTI configured for at least one carrier mapped to the logical channel, based on the channel carrier configuration information;
- wherein receiving the first message comprises:
- receiving a Radio Resource Control (RRC) message carrying the channel carrier configuration information sent by the base station;
- and
- the one or more processors are further configured to:
- when the RRC message is an RRC message instructing user equipment to switch to an inactive state, the RRC message further carries at least respective numerologies or TTIs configured for different carriers associated with the logical channel;
- determine a carrier for a cell when the user equipment in the inactive state resides in the cell;
- and
- determine at least a numerology or a TTI configured for the carrier for the cell with respect to the logical channel, based on the carrier for the cell.
12 more elements
A base station, comprising:
- one or more processors;
- and
- a non-transitory computer-readable storage medium storing instructions executable by the one or more processors;
- wherein the one or more processors are configured to:
- generate a first message, wherein the first message is a message carrying channel carrier configuration information, wherein the channel carrier configuration information indicates at least one of numerology or TTI configuration information for a logical channel;
- and
- send the first message to user equipment, wherein the first message is configured for the user equipment to determine at least one carrier mapped to the logical channel and at least a numerology or a TTI configured for at least one carrier mapped to the logical channel;
- wherein the first message comprises a Radio Resource Control (RRC) message;
- and
- wherein when the RRC message is an RRC message instructing user equipment to switch to an inactive state, the RRC message further carries at least respective numerologies or TTIs configured for different carriers associated with the logical channel, such that the user equipment determines a carrier for a cell when the user equipment in the inactive state resides in the cell, and determines at least a numerology or a TTI configured for the carrier for the cell with respect to the logical channel, based on the carrier for the cell.
