Random access method and apparatus and resource configuration method and apparatus
A random access method and apparatus and resource configuration method and apparatus. The random access apparatus includes: a third receiving unit configured to, on a physical random access channel resource, receive a random access preamble transmitted by a terminal equipment; wherein the random access preamble is used to indicate that the terminal equipment has sidelink data to be transmitted, and/or the physical random access channel resource is used to indicate that the terminal equipment has sidelink data to be transmitted; and a second transmitting unit configured to transmit a random access response to the terminal equipment. By indicating in the random access procedure to the network device that the terminal equipment has a sidelink MAC CE to be transmitted, it may be avoided that the network device does not learn that the terminal equipment has a sidelink MAC CE to be transmitted, so that the network device allocates resources for the sidelink, and resource consumption may be lowered.
1 . A scheduling request transmission apparatus, applicable to a terminal equipment side, wherein the apparatus comprises:
a memory; and
processor circuitry coupled to the memory and configured to:
trigger a scheduling request when the terminal equipment has sidelink CSI reporting to be transmitted and there exists no currently available sidelink resource;
transmit a scheduling request to a network device; and
cancel the scheduling request when the sidelink CSI reporting is outdated,
wherein the sidelink CSI reporting is outdated when maximum latency of the sicelink CSI reporting is exceeded,
wherein, when there exists a valid PUCCH resource in a scheduling request configuration, the processor circuitry is further configured to transmit the scheduling request by using the PUCCH resource in the scheduling request configuration, and
wherein,
the processor circuitry is further configured to receive scheduling request configuration corresponding to the sidelink CSI reporting transmitted by the network device via an RRC reconfiguration message, and
at most one PUCCH resource is configured per bandwidth part for the scheduling request to which the sidelink CSI reporting corresponds.
2 . The apparatus according to claim 1 , wherein the maximum latency of the sidelink data is exceeded when the transmission of the scheduling request exceeds the maximum latency of the sidelink data.
3 . The apparatus according to claim 1 , wherein the scheduling request is a pending scheduling request when the scheduling request is triggered.
4 . The apparatus according to claim 1 , wherein the maximum latency of the sidelink data is 4 to 20 milliseconds.
5 . A scheduling request reception apparatus, applicable to a network equipment side, wherein the apparatus comprises:
a memory; and
processor circuitry coupled to the memory and configured to:
receive a scheduling request transmitted by a terminal equipment after the scheduling request is triggered when the terminal equipment has sidelink CSI reporting to be transmitted and there exists no currently available sidelink resource; and
fail in receiving the scheduling request transmitted by the terminal equipment when the sidelink CSI reporting is outdated,
wherein the sidelink CSI reporting is outdated when maximum latency of the sidelink CSI reporting is exceeded, and
wherein, when there exists a valid PUCCH resource in a scheduling request configuration, the processor circuitry is further configured to receive the scheduling request by using the PUCCH resource in the scheduling request configuration,
wherein,
the processor circuitry is further configured to transmit scheduling request configuration corresponding to the sidelink CSI reporting via an RRC reconfiguration message, and
at most one PUCCH resource is configured per bandwidth part for the scheduling request to which the sidelink CSI reporting corresponds.
6 . The apparatus according to claim 5 , wherein the maximum latency of the sidelink data is exceeded when the transmission of the scheduling request exceeds the maximum latency of the sidelink data.
7 . The apparatus according to claim 5 , wherein the scheduling request is a pending scheduling request when the scheduling request is triggered.
8 . The apparatus according to claim 5 , wherein the maximum latency of the sidelink data is 4 to 20 milliseconds.
