Resource indication method and apparatus and communication system
A resource indication method and apparatus and communication system. The resource indication method includes: receiving by a terminal equipment third indication information used for dynamically indicating time domain resources in a resource pool transmitted by a network device, and/or receiving by a terminal equipment first indication information used for indicating first time domain resources belonging to a resource pool and transmitted by a network device. By indicating by the indication information which time-domain resources in the semi-persistently configured and/or dynamically configured time-domain resources may be contained in the resource pool, the V2X terminal equipment may perform data transceiving by using the resources in the resource pool, thereby supporting V2X communication in a future communication system.
1. A resource indication apparatus, comprising:
a memory; and
processor circuity coupled to the memory and configured to:
receive first indication information, the first indication information being used for indicating at least one slot belonging to a resource pool;
wherein transmission directions of symbols in each of the at least one slot are configured by semi-persistent configuration information, and
wherein the first indication information is relevant to a slot that contains uplink symbols of a number more than or equal to a first predetermined number and the first indication is irrelevant to a slot that contains uplink symbols of a number not more than or less than the first predetermined number;
transmit sidelink data on uplink symbols within the first predetermined number of uplink symbols in the at least one slot belonging to the resource pool.
2. The apparatus according to claim 1 , wherein the first indication information is a bitmap.
3. The apparatus according to claim 1 , wherein the processor circuitry is further configured to:
receive the semi-persistent configuration information transmitted by a network device, the semi-persistent configuration information being used for configuring transmission direction types of the symbols in the slots; wherein the transmission direction types comprise uplink, downlink, and flexible.
4. A resource indication apparatus, comprising:
a memory; and
processor circuitry couple to the memory and configured to;
transmit semi-persistent configuration information; and
transmit first indication information, the first indication information being used for indicating at least one slot belonging to a resource pool,
wherein transmission directions of the symbols in each of the at least one slot are configured by the semi-persistent configuration information, and
wherein the first indication information is relevant to a slot that contains uplink symbols of a number more than or equal to a first predetermined number and the first indication information is irrelevant to a slot that contains uplink symbols of a number not more than or less than the first predetermined number.
