Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a first asymmetric uplink carrier aggregation method according to the present invention, and as shown in fig. 1, the method of this embodiment may include:
s101, a base station decomposes N downlink carriers and M uplink carriers into a plurality of carrier aggregation clusters, wherein each carrier aggregation cluster comprises a downlink carrier and K uplink carriers, N is less than or equal to M, K is an integer greater than or equal to 1, one uplink carrier corresponding to the downlink carrier and the downlink carrier form a main carrier, and the rest K-1 uplink carriers are auxiliary carriers.
Specifically, for example, as shown in fig. 2, fig. 2 is a schematic diagram of N downlink carriers and M uplink carriers, fig. 3 is a schematic diagram of carrier aggregation decomposition, as shown in fig. 3, a base station decomposes N downlink carriers and M uplink carriers into a plurality of carrier aggregation clusters, each carrier aggregation cluster includes one downlink carrier and at least one uplink carrier, and fig. 4 is a schematic diagram of a primary carrier and a secondary carrier, as shown in fig. 4, when a decomposed carrier aggregation cluster includes one downlink carrier and K uplink carriers, one uplink carrier and one downlink carrier corresponding to the downlink carrier are defined to form the primary carrier, and the remaining K-1 uplink carriers are defined as the secondary carriers.
Wherein, the K uplink carriers contained in each carrier aggregation cluster are at least one of the following carriers: continuous carriers within the same frequency band; non-continuous carriers within the same frequency band; carriers in different frequency bands.
S102, the base station carries out carrier aggregation on the multiple carrier aggregation clusters.
Specifically, the carrier aggregation of a plurality of carrier aggregation clusters by the base station is actually the aggregation between the primary carriers. For multiple carrier aggregation clusters, each carrier aggregation cluster is a Cell (Cell), and the base station performs carrier aggregation on the multiple carrier aggregation clusters, which may be, for example: the method includes aggregating primary carriers of multiple carrier aggregation clusters, allocating multiple carrier aggregation clusters to each UE, designating one of the carrier aggregation clusters as a primary Cell (primary Cell, abbreviated as PCell) and the other carrier clusters as secondary cells (secondary cells, abbreviated as scells), and scheduling resources in the PCell/SCell through respective Physical Downlink Control Channels (PDCCHs) in the PCell/SCell during scheduling, or performing cross-Cell scheduling.
In the asymmetric uplink carrier aggregation method provided in this embodiment, a base station decomposes a downlink carrier and an uplink carrier into multiple carrier aggregation clusters, where each carrier aggregation cluster includes one downlink carrier and K uplink carriers, and then performs carrier aggregation on the multiple carrier aggregation clusters. Therefore, carrier aggregation with downlink carrier waves smaller than uplink carrier waves can be realized, and a scene that the uplink service requirement is larger than the downlink service requirement can be further met.
Further, due to the scarcity of spectrum resources, it is difficult to obtain an authorized uplink spectrum meeting the uplink service requirement when acquiring an authorized uplink carrier in asymmetric uplink carrier aggregation, and therefore, in the embodiment of the present invention, the base station selects an authorized frequency band as a main carrier, and selects a white spectrum as an auxiliary carrier. The actual utilization rate of the existing white spectrum frequency is very low, and a spectrum with small interference can be selected to be used as an uplink carrier aggregated by asymmetric uplink carriers through interference measurement. When the white spectrum is used as the uplink auxiliary carrier of the asymmetric carrier aggregation, because there is no base station transmission, only terminal transmission, lower terminal transmission power and shorter antenna frame height, the interference to the original system (such as Digital Television (DTV) and the like) after the white spectrum is introduced can be solved better.
Fig. 5 is a flowchart of a second asymmetric uplink carrier aggregation method according to the present invention, and as shown in fig. 5, the method of this embodiment may further include, on the basis of the method shown in fig. 1, before S101:
s103, the base station selects a downlink carrier and an uplink carrier as a main carrier from the authorized frequency band, and the base station selects an uplink carrier as an auxiliary carrier from the white spectrum.
The base station selects an uplink carrier serving as an auxiliary carrier from the white spectrum, and specifically may be:
and S1031, the base station carries out interference measurement on each narrow-band frequency point in the preset white-spectrum frequency band to obtain an interference measurement value of each narrow-band frequency point.
For example, for a wide white spectrum, assume that a relatively narrow-band frequency bin is contained: f. of0f1…fN-1. The base station needs to perform interference measurement on each narrowband frequency point in a preset frequency band to obtain an interference measurement value I of each narrowband frequency point0I1…IN-1。
S1032, the base station selects the frequency band with the minimum interference measurement value as the uplink carrier of the auxiliary carrier according to the obtained interference measurement value. Or,
and the base station selects a frequency band as the uplink carrier of the auxiliary carrier according to the obtained interference measurement value, the blocking characteristic and the interference characteristic.
Wherein, the blocking characteristic means that the selected auxiliary carrier frequency point needs to meet the blocking characteristic of the base station, and the interference characteristic means that: for some narrow-band strong interference, the base station may shield and avoid the interference through a Resource Block (RB), and at this time, the interference remaining after the shielding needs to be considered. Furthermore, compared with the method only considering the interference measurement value, the method is more accurate in the mode of comprehensively selecting the frequency band as the auxiliary carrier according to the interference measurement value, the blocking characteristic and the interference characteristic.
Specifically, for the uplink carrier selected as the secondary carrier from the white spectrum, the most important is interference measurement on the white spectrum, and the interference measurement accuracy determines the performance of asymmetric uplink carrier aggregation. The base station performs interference measurement on each narrowband frequency point in a preset white spectrum frequency band, which may include:
and the base station carries out periodic interference measurement on each narrowband frequency point in a preset frequency band according to the measurement period, the measurement length and the measurement starting time predefined by the base station.
In order to avoid the influence of interference in the system during interference measurement, the terminal is required to stop sending data at the measurement time, and the following two ways are adopted for the terminal to stop sending data at the measurement time: the base station does not schedule the end user any more during the measurement period determined by the measurement length and the measurement start time, or,
and the end user stops sending data in the measurement time period determined by the measurement length and the measurement starting time.
Specifically, before the base station performs periodic interference measurement on each narrowband frequency point in a preset frequency band according to a measurement period, a measurement length and a measurement start time predefined by the base station, the base station broadcasts and notifies the measurement period, the measurement length and the measurement start time to a terminal user, so that the terminal user stops sending data in a measurement time period determined by the measurement length and the measurement start time.
In the second way, the relevant interference measurement time information can be added to the broadcast channel: such as measurement period, measurement length, measurement start time, etc. The terminal receives the interference measurement time information, and can stop uplink transmission at the measurement time, and the base station can perform uplink interference measurement in the period of time and select a proper auxiliary carrier. When all base stations are configured with the same interference measurement time information, the base stations can be ensured to avoid receiving the interference of other cells when performing uplink interference measurement, thereby ensuring the accuracy of uplink interference measurement.
The interference of each base station is different, so that the center frequency points of the auxiliary carriers selected based on the white spectrum are also different. Since the frequency points of the white spectrum are only used for uplink, all measurements related to handover are still based on the downlink main carrier. Therefore, the switching is irrelevant to the selection of the auxiliary carrier and only relevant to the networking mode of the main carrier, if the main carrier adopts the same-frequency networking, the switching is the same-frequency switching based on the main carrier, and if the main carrier adopts the different-frequency networking, the switching is the different-frequency switching based on the main carrier.
The asymmetric uplink carrier aggregation method provided in this embodiment realizes that, in a scenario that an uplink service requirement is greater than a downlink service requirement, a base station selects a downlink carrier and an uplink carrier as a main carrier from an authorized frequency band, and the base station selects an uplink carrier as an auxiliary carrier from a white spectrum, thereby solving the problem of availability of the auxiliary carrier in uplink carrier aggregation. In addition, in the embodiment, the white spectrum is only used for the uplink, only the terminal transmits, the power of the terminal is low, and the overhead height is low, so that the problem of coexistence with other systems can be solved well. Further increasing the availability of white spectrum.
