Method and device for configuring available HARQ process of logical channel
The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates. According to an embodiment of the present disclosure, a method performed by a terminal in a communication system is provided. The method performed by the terminal comprises the steps of: receiving, from a base station, logical channel configuration information that includes first information about an available hybrid automatic repeat request (HARQ) mode corresponding to a logical channel, and serving cell configuration information that includes second information about an available HARQ mode for each HARQ process ID; performing a logical channel prioritization procedure on the basis of the first information and the second information; and transmitting uplink data to the base station on the basis of the result of the logical channel prioritization procedure.
1 . A method of a terminal in a communication system, the method comprising:
receiving, from a base station, a radio resource control (RRC) message including configuration information on a logical channel and configuration information on a serving cell including information on a hybrid automatic repeat request (HARQ) type corresponding to HARQ process identifier (ID) of the serving cell;
identifying an uplink grant associated with the HARQ process ID;
if an allowed HARQ type for the logical channel is configured by the configuration information on the logical channel, selecting the logical channel allowed to use the HARQ type corresponding to the HARQ process ID, for logical channel prioritization, based on the information; and
transmitting, to the base station, uplink data of the selected logical channel based on the uplink grant,
wherein, if the allowed HARQ type for the logical channel is not configured by the configuration information on the logical channel, all HARQ processes of the serving cell are used for the logical channel without HARQ type restriction.
2 . The method of claim 1 , further comprising:
allocating a resource for the uplink grant based on the logical channel prioritization,
wherein the uplink data is transmitted in the allocated resource.
3 . The method of claim 2 , wherein the uplink grant is identified based on downlink control information (DCI) received from the base station.
4 . The method of claim 1 , wherein the allowed HARQ type is either a first mode or a second mode.
5 . A method of a base station in a communication system, the method comprising:
transmitting, to a terminal, a radio resource control (RRC) message including configuration information on a logical channel and configuration information on a serving cell including information on a hybrid automatic repeat request (HARQ) type corresponding to HARQ process identifier (ID) of the serving cell; and
if an allowed HARQ type for the logical channel is configured by the configuration information on the logical channel, receiving, from the terminal, uplink data of a selected logical channel based on an uplink grant associated with the HARQ process ID,
wherein the selected logical channel is allowed to use the HARQ type corresponding to the HARQ process ID, for logical channel prioritization, based on the information, and
wherein, if the allowed HARQ type for the logical channel is not configured by the configuration information on the logical channel, all HARQ processes of the serving cell are used for the logical channel without HARQ type restriction.
6 . The method of claim 5 ,
wherein the uplink data is received in a resource, allocated based on the logical channel prioritization, for the uplink grant.
7 . The method of claim 6 , wherein the uplink grant is identified based on downlink control information (DCI) transmitted to the terminal.
8 . The method of claim 5 , wherein the allowed HARQ type is either a first mode or a second mode.
9 . A terminal of a communication system, the terminal comprising:
a transceiver; and
a controller connected to the transceiver and configured to:
receive, from a base station, a radio resource control (RRC) message including configuration information on a logical channel and configuration information on a serving cell including information on a hybrid automatic repeat request (HARQ) type corresponding to HARQ process identifier (ID) of the serving cell,
identify an uplink grant associated with the HARQ process ID,
if an allowed HARQ type for the logical channel is configured by the configuration information on the logical channel, select the logical channel allowed to use the HARQ type corresponding to the HARQ process ID, for logical channel prioritization, based on the information, and
transmit, to the base station, uplink data of the selected logical channel based on the uplink grant,
wherein, if the allowed HARQ type for the logical channel is not configured by the configuration information on the logical channel, all HARQ processes of the serving cell are used for the logical channel without HARQ type restriction.
10 . The terminal of claim 9 , wherein the controller is further configured to
allocate a resource for the uplink grant with regard to data based on the logical channel prioritization, and
wherein the uplink data is transmitted in the allocated resource.
11 . The terminal of claim 10 , wherein the uplink grant is identified based on downlink control information (DCI) received from the base station.
12 . The terminal of claim 9 , wherein the allowed HARQ type is either a first mode or a second mode.
13 . A base station of a communication system, the base station comprising:
a transceiver; and
a controller connected to the transceiver and configured to:
transmit, to a terminal, a radio resource control (RRC) message including configuration information on a logical channel and configuration information on a serving cell including information on a hybrid automatic repeat request (HARQ) type corresponding to HARQ process identifier (ID) of the serving cell, and
if an allowed HARQ type for the logical channel is configured by the configuration information on the logical channel, receive, from the terminal, uplink data of a selected logical channel based on an uplink grant associated with the HARQ process ID,
wherein the selected logical channel is allowed to use the HARQ type corresponding to the HARQ process ID, for logical channel prioritization, based on the information, and
wherein, if the allowed HARQ type for the logical channel is not configured by the configuration information on the logical channel, all HARQ processes of the serving cell are used for the logical channel without HARQ type restriction.
14 . The base station of claim 13 , wherein the uplink data is received in a resource, allocated based on the logical channel prioritization, for the uplink grant.
15 . The base station of claim 14 , wherein the uplink grant is identified based on downlink control information (DCI) transmitted to the terminal.
16 . The base station of claim 13 , wherein the allowed HARQ type is either a first mode or a second mode.
