Abstract

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.

Claims (14)

1 . A communication apparatus, comprising:

a receiver configured to receive first indication information, the first indication information being used for indicating at least one time domain resource belonging to a resource pool used for sidelink transmission; and

a transmitter configured to transmit sidelink data on uplink symbols in the at least one time domain resource belonging to the resource pool, wherein

transmission directions of symbols in each of the at least one time domain resource are configured by semi-persistent configuration information, and

the first indication information is relevant to a time domain resource that includes uplink symbols of a number more than or equal to a first predetermined number and the first indication information is irrelevant to a time domain resource that includes uplink symbols of a number not more than or less than the first predetermined number.

2 . The communication apparatus according to claim 1 , wherein the first indication information is a bitmap.

3 . The communication apparatus according to claim 1 , wherein the receiver 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 symbols in time domain resources, wherein the transmission direction types comprise uplink, downlink, and flexible.

4 . The communication apparatus according to claim 3 , wherein the first predetermined number of uplink symbols includes all the uplink symbols within a slot.

5 . The communication apparatus according to claim 1 , wherein the first indication information indicates the at least one time domain resource belonging to the resource pool such that the at least one time domain resource does not include downlink symbol(s) nor flexible symbol(s).

6 . A communication apparatus comprising:

a transmitter configured to transmit first indication information, the first indication information being used for indicating at least one time domain resource belonging to a resource pool used for sidelink transmission; and

a receiver configured to receive sidelink data on uplink symbols in the at least one time domain resource belonging to the resource pool, wherein

transmission directions of symbols in each of the at least one time domain resource are configured by semi-persistent configuration information, and

the first indication information is relevant to a time domain resource that includes uplink symbols of a number more than or equal to a first predetermined number and the first indication information is irrelevant to a time domain resource that includes uplink symbols of a number not more than or less than the first predetermined number.
