Abstract
The present application provides a method and a device in a communication node for wireless communications. A communication node receives first information, second information and a first signaling, herein, only a former of the first information and the second information belongs to legacy SIB1; transmits a first message on a first radio resource, the first message comprises a random access preamble, the first radio resource belongs to a first resource set or the first radio resource belongs to a second resource set; herein, the first resource set depends on an indication of the legacy SIB1, and the first signaling is used to determine the second resource set. The scheme in the present application can reduce the random access delay of a legacy UE.
Claims20
A first node for wireless communications, comprising:
- a first receiver, receiving first information, second information and a first signaling, only a former of the first information and second information belonging to legacy SIB1;
- and
- a first transmitter, transmitting a first message on a first radio resource, the first message comprising a random access preamble, the first radio resource belonging to a first resource set or the first radio resource belonging to a second resource set;
- wherein the first resource set depends on an indication of the legacy SIB1, and the first signaling is used to determine the second resource set;
- for any radio resource in the first resource set, whether a candidate for the first radio resource comprises the radio resource depends on at least one of the following:
- whether reception quality of RS resources associated with the radio resource is greater than or not lower than a first threshold, and the first threshold depends on a configuration of the first information;
- whether a candidate for the first radio resource comprises radio resources of the second resource set;
- for any radio resource in the second resource set, whether a candidate for the first radio resource comprises the radio resources depends on whether reception quality of RS resources associated with the radio resource is greater than or not lower than a second threshold, and the second threshold depends on a configuration of the second information.

A second node for wireless communications, comprising:
- a second transmitter, transmitting first information, second information and a first signaling, only a former of the first information and second information belonging to legacy SIB1;
- and
- a second receiver, receiving a first message on a first radio resource, the first message comprising a random access preamble, the first radio resource belonging to a first resource set or the first radio resource belonging to a second resource set;
- wherein the first resource set depends on an indication of the legacy SIB1, and the first signaling is used to determine the second resource set;
- for any radio resource in the first resource set, whether a candidate for the first radio resource comprises the radio resource depends on at least one of the following:
- whether reception quality of RS resources associated with the radio resource is greater than or not lower than a first threshold, and the first threshold depends on a configuration of the first information;
- whether a candidate for the first radio resource comprises radio resources of the second resource set;
- for any radio resource in the second resource set, whether a candidate for the first radio resource comprises the radio resources depends on whether reception quality of RS resources associated with the radio resource is greater than or not lower than a second threshold, and the second threshold depends on a configuration of the second information.
