Description
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a resource allocation method and apparatus, and a computer storage medium.
Background
In a Long Term Evolution (LTE) system, a period for a terminal to monitor a Physical Downlink Control Channel (PDCCH) is fixed, for example, the PDCCH is monitored once every subframe (i.e., 2 slots). The PDCCH monitoring time (PDCCH monitoring duration) is not settable.
In the technical discussion of 5G NR, the concept of Control Resource Set (CORESET) is introduced, in which PDCCH is transmitted. The time slot of the CORESET is configured by a PDCCH Monitoring period (PDCCH Monitoring periodicity) parameter- (Monitoring-periodicity-PDCCH-slot) and a PDCCH Monitoring offset (PDCCH Monitoring offset) parameter- (Monitoring-offset-PDCCH-slot). The smaller the CORESET monitoring periodicity is, the more frequent PDCCH monitoring can be realized, and the smaller the PDCCH receiving time delay can be realized.
Although the above scheme can adjust the density of the PDCCH Monitoring scheduling by adjusting the PDCCH Monitoring period, thereby balancing the relationship between the PDCCH Monitoring delay and the power consumption of the terminal, however, the Monitoring-offset-PDCCH-slot in each Monitoring period can only be the same, and the position of the PDCCH Monitoring scheduling in the Monitoring period cannot be flexibly adjusted, which greatly limits the resource configuration flexibility of the PDCCH, brings resource allocation fragments, and causes the waste of spectrum resources.

Detailed Description
So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.
Fig. 1 is a schematic diagram of a CORESET Monitoring period being 10 slots, and as shown in fig. 1, a Monitoring-periodicity-PDCCH-slot is configured to be 10 slots (slots), that is, a PDCCH is monitored once every 10 slots, and a Monitoring slot is located in a 4 th slot of each period, that is, a Monitoring-offset-PDCCH-slot is 3.
Fig. 2 is a schematic diagram of a CORESET Monitoring period having 5 slots, and as shown in fig. 2, 5 slots are configured in a Monitoring-periodicity-PDCCH-slot, and the Monitoring slot is located in the 4 th slot of each period, that is, 3 slots in the Monitoring-periodicity-PDCCH-slot.
The difference between fig. 2 and fig. 1 is that the monitoring period is shortened by half, which helps to obtain smaller PDCCH reception delay. However, the Monitoring-offset-PDCCH-slot in each Monitoring period can only be the same, and the position of the PDCCH Monitoring event in the Monitoring period cannot be flexibly adjusted, so that the resource configuration flexibility of the PDCCH is greatly limited, resource allocation fragments are brought, and the waste of spectrum resources is caused.
For example, in a multi-beam (multi-beam) system, a terminal receives a PDCCH only in a transmission time window of 1-2 beams, without monitoring the PDCCH in transmission time windows of other beams. In addition, different beams need different monitoring densities in one monitoring period due to different numbers of covered users. In this case, the use of a uniform PDCCH monitoring period may cause unnecessary additional complexity, power consumption of the terminal, and resource waste.
For another example, in order to maintain Forward compatibility (Forward compatibility), the system needs to reserve partial time domain resources (reserved resources), and in these time domain resources, the terminal also does not need to monitor the PDCCH. In this case, the use of a uniform PDCCH monitoring period also brings unnecessary extra complexity and terminal power consumption.
For another example, in a TDD wireless communication system with a flexibly configurable frame structure, with a conventional uniform PDCCH monitoring period, a PDCCH monitoring event is likely to be located in a time domain resource that cannot be used for downlink transmission, so that the PDCCH monitoring event cannot be used.
According to the technical scheme of the embodiment of the invention, the time domain monitoring time of the PDCCH can be configured through the bitmap with two levels of time slots and symbols, and the non-uniform PDCCH monitoring occasion can be indicated, so that the multi-beam transmission, forward compatible resource reservation and other scenes of the terminal can be supported, the complexity and the power consumption of the terminal are reduced, meanwhile, the resource configuration flexibility of the PDCCH is improved, and the utilization rate of spectrum resources is improved.

For example: the first cycle is 10 time slots and the first bitmap is 0001001000. assuming a bit value of 1 indicates that the corresponding time slot is the first time slot including the first resource, the first bitmap may indicate that the 4 th time slot and the 7 th time slot are the first time slot including the first resource. It should be understood that a bit value of 0 may also represent that the corresponding time slot is the first time slot comprising the first resource.
In an embodiment of the present invention, the second configuration information is used to configure a starting symbol position of the first resource in at least one of the first slots, and in an implementation, the second configuration information implements configuration of a starting symbol through a second bitmap, where the second bitmap is used to indicate a starting symbol position of the first resource in at least one of the first slots.

In a specific implementation, a slot includes 14 symbols, the position of the start symbol has 14 cases, and the second bitmap can be implemented by 4 bits, for example: 0000 represents the position of the start symbol as the first symbol, 0001 represents the position of the start symbol as the second symbol, 0010 represents the position of the start symbol as the third symbol, and so on.

In order to determine which configuration information to use for configuring the position of the first time slot including the first resource within the first period, the network device sends fifth configuration information to the terminal device, the fifth configuration information indicating whether to use the first configuration information or the third configuration information for indicating the position of the first time slot. Further, the fifth configuration information is any one of RRC signaling, system information, DCI, and MAC CE.
