摘要: This application provides a data transmission method and an apparatus. The method includes: receiving first information from a network device on a first frequency domain resource, where the first information indicates to switch to a second frequency domain resource; determining a first time unit based on the first information, where the first time unit includes a second time unit; and switching from the first frequency domain resource to the second frequency domain resource in the second time unit, and performing data transmission on the first frequency domain resource and/or the second frequency domain resource in a period of time other than the second time unit in the first time unit. According to the foregoing method, a terminal device may perform the data transmission in a period of time other than time for frequency domain resource switching in the first time unit, to improve a data throughput rate of the data transmission and reduce impact of frequency domain resource switching on the data transmission. In addition, fast switching between different frequency domain resources can be implemented, to obtain a higher frequency diversity or selective scheduling gain and faster avoidance of a high-priority service.

摘要: This application discloses a data transmission method and a communications apparatus, to reduce system overheads and improve retransmission efficiency. The method includes: receiving downlink control information DCI from a network device, where the DCI includes a first bit and a second bit, and the first bit and the second bit are respectively used to indicate two new data indicators NDIs associated with two transport blocks TBs scheduled in the DCI; and performing, based on the first bit and the second bit in the DCI, uplink data transmission or downlink data transmission in HARQ processes corresponding to the two TBs. The two NDIs associated with the two TBs scheduled in one piece of DCI are carried in the DCI, so that DCI overheads are not increased as much as possible. In addition, the first bit and the second bit in the DCI are respectively used to indicate the NDIs associated with the two TBs. In other words, different NDIs are independently indicated by using different bit indication bits. Therefore, a TB that needs to be retransmitted can be accurately distinguished, thereby improving retransmission efficiency. The method and device provided in the embodiments of this application improve network coverage capacity, and may be applied to an internet of things such as an MTC, an IoT, an LTE-M, or an M2M.

摘要: A resource configuration method and an apparatus are provided. A serial number N BWP start of a common resource block CRB corresponding to a start resource block RB of a BWP configured by a network device for a terminal device and a quantity L RBs of consecutive RBs occupied by the BWP meet one or more of the following conditions: N BWP start mod K=0; and N BWP start + L RBs mod K = 0 , where mod is a remainder operation, and K is a positive integer. Based on the foregoing method, during BWP configuration, it can be ensured that the serial number of the start CRB of the BWP and/or a serial number of a CRB corresponding to a last RB included in the BWP each are/is an integer multiple of K. In this way, it can be ensured that more RBs can be used in a CORESET, thereby increasing resource utilization.

摘要: This application provides a multi-antenna operation mode indication method and an apparatus, and relates to the communication field, to resolve a problem in the existing technology that increased power consumption and a resource waste are caused because a terminal device still operates in a multi-user multiple-input multiple-output MU-MIMO mode by default in a single-port transmission mode. The method includes: A network device sends indication information to a terminal device, to indicate that a multi-antenna operation mode of the terminal device is single-user multiple-input multiple-output SU-MIMO or multi-user multiple-input multiple-output NW-MIMO. The terminal device determines, based on the indication information from the network device, whether a demodulation reference signal DMRS port number corresponding to the terminal device and a DMRS port number not corresponding to the terminal device are allocated to another terminal device, to adjust the multi-antenna operation mode.

摘要: Embodiments of this application provide a resource allocation method, an apparatus, and a system, to reduce a waste of resources and improve resource utilization. In the method, after determining a BWP allocated to a terminal device, where the BWP includes a first BWP, and determining a first value, a network device sends first indication information to the terminal device, where the first indication information is used to indicate the first value. The terminal device determines the BWP allocated by the network device to the terminal device, where the BWP includes the first BWP, and receives the first indication information from the network device. Then, when the first value is used to indicate a resource block group RBG size corresponding to the first BWP, the RBG size corresponding to the first BWP is determined based on the first value. Alternatively, when the first value is used to determine a resource indication value RIV set corresponding to the first BWP, the RIV set corresponding to the first BWP is determined based on the first value.

摘要: A gap determining method and a device are provided. The gap determining method includes: A terminal device receives first configuration information and second configuration information from a network device. The terminal device receives scheduling information from the network device, where the scheduling information is used to schedule N transport blocks carried on a first channel. The terminal device determines a downlink gap of the first channel based on the first configuration information. The terminal device determines a first gap between the N transport blocks based on the second configuration information. When the terminal device determines that a preset condition is satisfied, the terminal device determines that a gap part that is included in the first gap and that overlaps with the downlink gap is postponed in time domain and that a gap part obtained through postponing does not overlap with the downlink gap, where the preset condition includes that the first gap includes the gap part that overlaps with the downlink gap; or when the first gap includes a gap part that overlaps with the downlink gap, the terminal device determines that the gap part that is included in the first gap and that overlaps with the downlink gap belongs to the downlink gap.

摘要: A communication method and apparatus are provided, where the method includes: determining, by a first device according to a first preset rule, a first resource in at least two preset resources corresponding to a same gap before a first paging occasion PO; and monitoring, by the first device, at least one wake-up signal sequence on the first resource. According to the foregoing method, the first resource used by the first device for monitoring the wake-up signal sequence is determined according to the first preset rule. Therefore, this avoids that the first device always monitors wake-up signal sequences on one resource, and is unnecessarily woken up because common wake-up signal sequences are often received, and consequently a false alarm probability that the first device is woken up is quite high.
