Method and apparatus for reduced capability terminal to perform random access using a plurality of PUCCH common configuration in mobile wireless communication system
A method and apparatus for accessing a NR cell in a mobile communication system are provided. Method for accessing a NR cell includes receiving in a first cell, by a terminal from a base station, a System Information Block1 and performing, by the terminal, random access procedure based on a timeAlignmnetTimer in the first uplink configuration and a second pucch-ConfigCommon in the second uplink configuration.
1. A method performed by a terminal, the method comprising:
receiving in a first cell, by a terminal from a base station, a system information, wherein the system information comprises at least a first uplink configuration;
determining, by the terminal, a presence of a second uplink configuration in the system information; and
performing in the first cell, by the terminal with the base station, a random access procedure based on a time alignment timer value in the first uplink configuration and a second Physical Uplink Control Channel (PUCCH) configuration in the second uplink configuration in case that the second uplink configuration is present in the system information,
wherein the first uplink configuration comprises the time alignment timer value and a first PUCCH configuration, and
wherein the second uplink configuration, which comprises the second PUCCH configuration, does not comprise the time alignment timer value.
2. The method of claim 1 ,
wherein the random access procedure is performed based on the time alignment timer value in the first uplink configuration and the first PUCCH configuration in the first uplink configuration in case that the second uplink configuration is not present in the system information.
3. The method of claim 1 ,
wherein the first PUCCH configuration includes a first PUCCH resource configuration and the second PUCCH configuration includes a second PUCCH resource configuration.
4. The method of claim 3 ,
wherein the performing the random access procedure further comprises:
applying by the terminal the time alignment timer value to a timer;
starting by the terminal the timer when a random access response is received; and
performing by the terminal a PUCCH transmission based on the second PUCCH resource configuration.
5. A terminal in a wireless communication system, the terminal comprising:
a transceiver configured to transmit and receive a signal; and
a controller configured to control the transceiver to:
receive in a first cell from a base station a system information, wherein the system information comprises at least a first uplink configuration;
determine a presence of a second uplink configuration in the system information; and
perform a random access procedure based on a time alignment timer value in the first uplink configuration and a second Physical Uplink Control Channel (PUCCH) configuration in the second uplink configuration in case that the second uplink configuration is present in the system information,
wherein the first uplink configuration comprises the time alignment timer value and a first PUCCH configuration, and
wherein the second uplink configuration, which information-comprises the second PUCCH configuration, does not comprise the time alignment timer value.
6. A method performed by a base station, the method comprising:
transmitting in a first cell, by a base station, a system information, wherein the system information comprises at least a first uplink configuration;
performing in the first cell, by the base station with a first type terminal, a random access procedure based at least in part on a time alignment timer value in the first uplink configuration and a first Physical Uplink Control Channel (PUCCH) configuration in the first uplink configuration; and
performing in the first cell, by the base station with a second type terminal, a random access procedure based at least in part on the time alignment timer value in the first uplink configuration and a second PUCCH configuration in a second uplink configuration,
wherein the first uplink configuration comprises the time alignment timer value and the first PUCCH configuration,
wherein the second uplink configuration, which comprises the second PUCCH configuration, does not comprise the time alignment timer value,
wherein the time alignment timer value in the first uplink configuration is applied to the first type terminal and the second type terminal, and
wherein the second PUCCH configuration is applied to the second type terminal.
